 Do I have to rewrite my programs in RPython?
 --------------------------------------------
 
-No.  And you shouldn't try.  PyPy always runs your code in its own interpreter, which is a
-full and compliant Python 2.7 interpreter.  RPython is only the
-language in which parts of PyPy itself are written and extension
-modules for it.  Not only is it not necessary for you to rewrite your
-code in RPython, it probably won't give you any speed improvements if you 
-try.
+No.  And you shouldn't try.  First and foremost, RPython is a language
+that is designed to write interpreters in.  It is a restricted subset of
+Python.  If you program is not an interpreter but tries to do "real
+things", like use *any* part of the standard Python library or *any*
+3rd-party library, then it is not RPython to start with.  You should
+only look at RPython if you try to `write your own interpreter`__.
+
+.. __: `how do I compile my own interpreters`_
+
+If your goal is to speed up Python code, then look at the regular PyPy,
+which is a full and compliant Python 2.7 interpreter (which happens to
+be written in RPython).  Not only is it not necessary for you to rewrite
+your code in RPython, it might not give you any speed improvements even
+if you manage to.
+
+Yes, it is possible with enough effort to compile small self-contained
+pieces of RPython code doing a few performance-sensitive things.  But
+this case is not interesting for us.  If you needed to rewrite the code
+in RPython, you could as well have rewritten it in C for example.  The
+latter is a much more supported, much more documented language `:-)`

 Environment variables can be used to fine-tune the following parameters:
 
- PYPY_GC_NURSERY        The nursery size.  Defaults to '4MB'.  Small values

- PYPY_GC_MAJOR_COLLECT  Major collection memory factor.  Default is '1.82',
-                        which means trigger a major collection when the
-                        memory consumed equals 1.82 times the memory
-                        really used at the end of the previous major
-                        collection.
+ PYPY_GC_NURSERY_CLEANUP The interval at which nursery is cleaned up. Must
+                         be smaller than the nursery size and bigger than the
+                         biggest object we can allotate in the nursery.
 
- PYPY_GC_GROWTH         Major collection threshold's max growth rate.
-                        Default is '1.4'.  Useful to collect more often
-                        than normally on sudden memory growth, e.g. when
-                        there is a temporary peak in memory usage.

- PYPY_GC_MAX            The max heap size.  If coming near this limit, it

-                        RPython MemoryError, and if that is not enough,

 Do I have to rewrite my programs in RPython?
 --------------------------------------------
 
-No.  And you shouldn't try.  PyPy always runs your code in its own interpreter, which is a
-full and compliant Python 2.7 interpreter.  RPython is only the
-language in which parts of PyPy itself are written and extension
-modules for it.  Not only is it not necessary for you to rewrite your
-code in RPython, it probably won't give you any speed improvements if you 
-try.
+No.  And you shouldn't try.  First and foremost, RPython is a language
+that is designed to write interpreters in.  It is a restricted subset of
+Python.  If you program is not an interpreter but tries to do "real
+things", like use *any* part of the standard Python library or *any*
+3rd-party library, then it is not RPython to start with.  You should
+only look at RPython if you try to `write your own interpreter`__.
+
+.. __: `how do I compile my own interpreters`_
+
+If your goal is to speed up Python code, then look at the regular PyPy,
+which is a full and compliant Python 2.7 interpreter (which happens to
+be written in RPython).  Not only is it not necessary for you to rewrite
+your code in RPython, it might not give you any speed improvements even
+if you manage to.
+
+Yes, it is possible with enough effort to compile small self-contained
+pieces of RPython code doing a few performance-sensitive things.  But
+this case is not interesting for us.  If you needed to rewrite the code
+in RPython, you could as well have rewritten it in C for example.  The
+latter is a much more supported, much more documented language `:-)`

 Do I have to rewrite my programs in RPython?
 --------------------------------------------
 
-No.  And you shouldn't try.  PyPy always runs your code in its own interpreter, which is a
-full and compliant Python 2.7 interpreter.  RPython is only the
-language in which parts of PyPy itself are written and extension
-modules for it.  Not only is it not necessary for you to rewrite your
-code in RPython, it probably won't give you any speed improvements if you 
-try.
+No.  And you shouldn't try.  First and foremost, RPython is a language
+that is designed to write interpreters in.  It is a restricted subset of
+Python.  If you program is not an interpreter but tries to do "real
+things", like use *any* part of the standard Python library or *any*
+3rd-party library, then it is not RPython to start with.  You should
+only look at RPython if you try to `write your own interpreter`__.
+
+.. __: `how do I compile my own interpreters`_
+
+If your goal is to speed up Python code, then look at the regular PyPy,
+which is a full and compliant Python 2.7 interpreter (which happens to
+be written in RPython).  Not only is it not necessary for you to rewrite
+your code in RPython, it might not give you any speed improvements even
+if you manage to.
+
+Yes, it is possible with enough effort to compile small self-contained
+pieces of RPython code doing a few performance-sensitive things.  But
+this case is not interesting for us.  If you needed to rewrite the code
+in RPython, you could as well have rewritten it in C for example.  The
+latter is a much more supported, much more documented language `:-)`

 NumPy status update #6

-Hello.

-This is the last two months update of the activities on the NumPyPy project.
+This is status report on PyPy's NumPyPy project.
 
 First the update:
 
 * **dtype support** - NumPy on PyPy now supports all the numeric dtypes in numpy,
   including non-native storage formats, longdouble, clongdouble and friends.
 
-* **missing ndarray attributes** - work has been made toward supporting the attributes
+* **missing ndarray attributes** - work has been made toward supporting the

   on ndarrays. We are progressing alphabetically, and have made it to d.
+  Unsupported attributes, and unsupported arguments to attribute calls
+  will raise a NotImplementedException.
 
 * **pickling support for numarray** - hasn't started yet, but next on the list
 
-* There has been some work on exposing FFT routines into numpypy.
+* There has been some work on exposing FFI routines in numpypy.
 
 More importantly, we're closing on being able to run the pure-python part of
 numpy without modifications. This is not getting us close to passing all

 To translate full RPython programs, there is the script ``translate.py`` in
-``translator/goal``. Examples for this are a slightly changed version of
+``rpython/translator/goal``. Examples for this are a slightly changed version of
 Pystone::
 
-    cd pypy/translator/goal
+    cd rpython/translator/goal
     python translate.py targetrpystonedalone
 
 This will produce the executable "targetrpystonedalone-c".

-       Waiting for connection on port 8888
-

 Do I have to rewrite my programs in RPython?
 --------------------------------------------
 
-No.  And you shouldn't try.  PyPy always runs your code in its own interpreter, which is a
-full and compliant Python 2.7 interpreter.  RPython is only the
-language in which parts of PyPy itself are written and extension
-modules for it.  Not only is it not necessary for you to rewrite your
-code in RPython, it probably won't give you any speed improvements if you 
-try.
+No.  And you shouldn't try.  First and foremost, RPython is a language
+that is designed to write interpreters in.  It is a restricted subset of
+Python.  If you program is not an interpreter but tries to do "real
+things", like use *any* part of the standard Python library or *any*
+3rd-party library, then it is not RPython to start with.  You should
+only look at RPython if you try to `write your own interpreter`__.
+
+.. __: `how do I compile my own interpreters`_
+
+If your goal is to speed up Python code, then look at the regular PyPy,
+which is a full and compliant Python 2.7 interpreter (which happens to
+be written in RPython).  Not only is it not necessary for you to rewrite
+your code in RPython, it might not give you any speed improvements even
+if you manage to.
+
+Yes, it is possible with enough effort to compile small self-contained
+pieces of RPython code doing a few performance-sensitive things.  But
+this case is not interesting for us.  If you needed to rewrite the code
+in RPython, you could as well have rewritten it in C for example.  The
+latter is a much more supported, much more documented language `:-)`

+ndarray, dtypes, ufuncs, and binfuncs. It has no linalg module, and
+lots is missing or incomplete.
 
-The branch will be complete when it is possible to run
-pypy -c 'import numpy;numpy.test()' and most tests pass.
+The strategy for completing this branch is:
+1. Find missing functionality or a failing test 
+2. Fix and test
 
-The strategy for completing the branch is:
-1. Set up pypy and cpython
-2. Find missing functionality or a failing test 
-3. Fix and test
+And in more detail (asusming you already can run tests on untranslated pypy:
+1a. download a nightly default branch version of pypy
+1a. copy the pypy executable into pypy/bin
+1c. update to this branch
+1d. run 'pypy/bin/pypy -c "import numpy; numpy.test(verbose=2)"
+2a. if the failure is pure python, update it on this branch.
+2b. if the failure is deeper, the failing part of the test probably
+    belongs in pypy/module/micronumpy/tests. Transplant the test there
+    and submit a patch to pypy
+Let us know you are planning to work on this, usually a note on IRC will be sufficient.
 
-Currently, 'import numpy' fails, since we are missing the
-c-level multiarray module.
+It may be possible to run on an untranslated pypy, the command line to do this is
+python pypy/bin/pyinteractive.py --withmod-micronumpy --withmod-struct --withmod-binascii --withmod-itertools --withmod-rctime --withmod-signal
+I didn't have much luck, even something as simple as 
+>>>import numpy as np
+>>>x = np.array([np.nan, np.inf])
+>>>print x
+failed, where a translated pypy succeeded, but ymmv
 
-So what we need in the short-term is to implement a python version of
-multiarray, work has been begun and it lives in lib_pypy/numpypy/multiarray.py
 
-And in more detail:
-1a. Get a recent trunk version of numpy
-1a. Install numpy into python, for extra points use virtualenv, by running 'python setup.py install' in the numpy trunk
-1c. Get the source tree for this branch of pypy
-1d. Download a nightly build of pypy and put the binary into the source tree, preferably at pypy/translator/goal/pypy. Alternatively, translate pypy
-2a. Run 'pypy/translator/goal/pypy -c 'import numpy;numpy.test()'
-2b. Something will fail. Poke around to see what the missing function or import is supposed to do. Hint: try http://docs.scipy.org/doc/numpy/reference/index.html
-2c. Let us know you are planning to work on this, usually a note on IRC will be sufficient.
-2c. Write a test for the missing functionality. For instance, tests for multiarray live in lib_pypy/numpypy/test/test_multiarray.py Try to think of corner cases: inappropriate arguments, missing defaults, and other wierd combination of arguments.
-3a. Try to find where numpy implemented it and stare at that till it makes sense.
-3b. Write some code
-3c. Test under pypy, python, and then think again about the tests, did you miss a corner case? Testing is done by:
- pypy/translator/pypy pytest.py lib_pypy/numpypy/test
-as well as
- python pytest.py lib_pypy/numpypy/test
-3d. Rerun 2a to make sure you accomplished what you set out to do
-3e. Commit and push your changes, if you are working on a fork let us know what you have done.

 * *New in version 0.4:* FILE.  You can declare C functions taking a
   ``FILE *`` argument and call them with a Python file object.  If needed,
   you can also do ``c_f = ffi.cast("FILE *", fileobj)`` and then pass around
   ``c_f``.

 be completed by a call to ``verify()``.
 
+.. versionadded:: 0.6
+   The standard type names listed above are now handled as *defaults*

+   If your ``cdef`` contains an explicit typedef that redefines one of
+   the types above, then the default described above is ignored.  (This

Log:	Enhance the dotviewer.
	- include Droid fonts (under Apache license)
	- allow for unicode by sending UTF-8 over the wire and force unicode
	decode on the other end
	- Make all text antialiased. It was already enabled unconditionally
	for the status bar and is now for the normal text, too.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,

+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the

+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.

+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the

+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

Log:	Tweak _getregkey(). The essential part is that for StackLocs it
	should return the ebp_offset, so that jump.py detects (on 32-bit)
	that some position is partially overlapping with a float because
	_getregkey() returned the previous value + WORD.

+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,

+
+      "Work" shall mean the work of authorship, whether in Source or

+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the

+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+    Stack arrays in sequence depth wise (along third axis).
+
+    Takes a sequence of arrays and stack them along the third axis
+    to make a single array. Rebuilds arrays divided by `dsplit`.
+    This is a simple way to stack 2D arrays (images) into a single
+    3D array for processing.
+
+    Parameters
+    ----------
+    tup : sequence of arrays
+        Arrays to stack. All of them must have the same shape along all
+        but the third axis.
+
+    Returns
+    -------
+    stacked : ndarray
+        The array formed by stacking the given arrays.
+
+    See Also
+    --------
+    vstack : Stack along first axis.
+    hstack : Stack along second axis.
+    concatenate : Join arrays.
+    dsplit : Split array along third axis.
+
+    Notes
+    -----
+    Equivalent to ``np.concatenate(tup, axis=2)``.
+
+    Examples
+    --------
+    >>> a = np.array((1,2,3))
+    >>> b = np.array((2,3,4))
+    >>> np.dstack((a,b))

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+   END OF TERMS AND CONDITIONS

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

    Now supported: the common GCC extension of anonymous nested
    structs/unions inside structs/unions.
 
+.. versionadded:: 0.6
+   Enum types follow the GCC rules: they are defined as the first of
+   ``unsigned int``, ``int``, ``unsigned long`` or ``long`` that fits
+   all numeric values.  Note that the first choice is unsigned.  In CFFI
+   0.5 and before, it was always ``int``.

+   `(****)` Supports simple slices as well: ``x[start:stop]`` gives another
+   cdata object that is a "view" of all items from ``start`` to ``stop``.
+   It is a cdata of type "array" (so e.g. passing it as an argument to a
+   C function would just convert it to a pointer to the ``start`` item).
+   As with indexing, negative bounds mean really negative indices, like in

+   of items or another array-like cdata object, but the length must match.

+   versions, you would get the enum's value as a string.  Now we follow the C
+   convention and treat them as really equivalent to integers.  To compare
    their value symbolically, use code like ``if x.field == lib.FOO``.
    If you really want to get their value as a string, use
    ``ffi.string(ffi.cast("the_enum_type", x.field))``.

+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

Log:	Moving the determination of the base integer type of an enum out of
	C code, into the 'cffi' package. This is work in progress; it
	should eventually permit the new test to fully pass. For now wrote
	a warning in the doc.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

Subject: [pypy-commit] lang-smalltalk default: (cfbolz,
 lwassermann around): stop using unwrapped strings as values and just
Message-ID: <20130222105143.ABBC31C01BF@cobra.cs.uni-duesseldorf.de>

Author: Carl Friedrich Bolz <cfbolz at gmx.de>
Branch: 
Changeset: r84:235293a3b353
Date: 2013-02-21 15:44 +0100
http://bitbucket.org/pypy/lang-smalltalk/changeset/235293a3b353/

Log:	(cfbolz, lwassermann around): stop using unwrapped strings as values
	and just compare them by identity, which Squeak guarantees to be
	unique.

	this actually makes the behaviour more correct, because now doing
	nasty stuff like manually changing the symbol won't break method
	dicts.

Subject: [pypy-commit] pypy missing-os-functions: Correctly detects the
 presence of fchmod and fchown.
Message-ID: <20130222155753.746091C4763@cobra.cs.uni-duesseldorf.de>

Author: Amaury Forgeot d'Arc <amauryfa at gmail.com>
Branch: missing-os-functions
Changeset: r61614:5e890c5dac82
Date: 2013-02-22 16:57 +0100
http://bitbucket.org/pypy/pypy/changeset/5e890c5dac82/

Log:	Correctly detects the presence of fchmod and fchown. Tests run and
	pass even with an old pypy which does (yet) not provide the
	functions.

	os.fchmod and os.fchown are not used anymore, they could probably be
	removed from ll_os.py

Subject: [pypy-commit] lang-smalltalk default: huge refactoring: remove the
 storage of the current frame on the interpreter.
Message-ID: <20130223114545.761151C0327@cobra.cs.uni-duesseldorf.de>

Author: Carl Friedrich Bolz <cfbolz at gmx.de>
Branch: 
Changeset: r92:91aa1165c8e2
Date: 2013-02-23 12:45 +0100
http://bitbucket.org/pypy/lang-smalltalk/changeset/91aa1165c8e2/

Log:	huge refactoring: remove the storage of the current frame on the
	interpreter. instead, just hand it around as an argument/result
	everywhere. this is a bit annoying in places, but makes the
	generated JIT code much better.

	 - the bytecode implementations now return the new frame, if they
	set one up
	 - the primitives now get and return a frame

+    Takes a sequence of arrays and stack them along the third axis
+    to make a single array. Rebuilds arrays divided by `dsplit`.
+    This is a simple way to stack 2D arrays (images) into a single
+    3D array for processing.
+
+    Parameters
+    ----------
+    tup : sequence of arrays
+        Arrays to stack. All of them must have the same shape along all
+        but the third axis.
+
+    Returns
+    -------
+    stacked : ndarray
+        The array formed by stacking the given arrays.
+
+    See Also
+    --------
+    vstack : Stack along first axis.
+    hstack : Stack along second axis.
+    concatenate : Join arrays.
+    dsplit : Split array along third axis.
+
+    Notes
+    -----
+    Equivalent to ``np.concatenate(tup, axis=2)``.
+
+    Examples
+    --------
+    >>> a = np.array((1,2,3))
+    >>> b = np.array((2,3,4))
+    >>> np.dstack((a,b))
+    array([[[1, 2],
+            [2, 3],
+            [3, 4]]])
+
+    >>> a = np.array([[1],[2],[3]])
+    >>> b = np.array([[2],[3],[4]])
+    >>> np.dstack((a,b))
+    array([[[1, 2]],
+           [[2, 3]],

-RPython
-=================
-
-RPython Definition
-------------------
-
-RPython is a restricted subset of Python that is amenable to static analysis.
-Although there are additions to the language and some things might surprisingly
-work, this is a rough list of restrictions that should be considered. Note
-that there are tons of special cased restrictions that you'll encounter
-as you go. The exact definition is "RPython is everything that our translation
-toolchain can accept" :)
-
-.. _`wrapped object`: coding-guide.html#wrapping-rules
-
-Flow restrictions
--------------------------
-
-**variables**
-
-  variables should contain values of at most one type as described in
-  `Object restrictions`_ at each control flow point, that means for
-  example that joining control paths using the same variable to
-  contain both a string and a int must be avoided.  It is allowed to
-  mix None (basically with the role of a null pointer) with many other
-  types: `wrapped objects`, class instances, lists, dicts, strings, etc.
-  but *not* with int, floats or tuples.
-
-**constants**
-
-  all module globals are considered constants.  Their binding must not
-  be changed at run-time.  Moreover, global (i.e. prebuilt) lists and
-  dictionaries are supposed to be immutable: modifying e.g. a global
-  list will give inconsistent results.  However, global instances don't
-  have this restriction, so if you need mutable global state, store it
-  in the attributes of some prebuilt singleton instance.
-
-
-
-**control structures**
-
-  all allowed, ``for`` loops restricted to builtin types, generators
-  very restricted.
-
-**range**
-
-  ``range`` and ``xrange`` are identical. ``range`` does not necessarily create an array,
-  only if the result is modified. It is allowed everywhere and completely
-  implemented. The only visible difference to CPython is the inaccessibility
-  of the ``xrange`` fields start, stop and step.
-
-**definitions**
-
-  run-time definition of classes or functions is not allowed.
-
-**generators**
-
-  generators are supported, but their exact scope is very limited. you can't
-  merge two different generator in one control point.
-
-**exceptions**
-
-+ fully supported
-+ see below `Exception rules`_ for restrictions on exceptions raised by built-in operations
-
-
-Object restrictions
--------------------------
-
-We are using
-
-**integer, float, boolean**
-
-  works.
-
-**strings**
-
-  a lot of, but not all string methods are supported and those that are
-  supported, not necesarilly accept all arguments.  Indexes can be
-  negative.  In case they are not, then you get slightly more efficient
-  code if the translator can prove that they are non-negative.  When
-  slicing a string it is necessary to prove that the slice start and
-  stop indexes are non-negative. There is no implicit str-to-unicode cast
-  anywhere. Simple string formatting using the ``%`` operator works, as long
-  as the format string is known at translation time; the only supported
-  formatting specifiers are ``%s``, ``%d``, ``%x``, ``%o``, ``%f``, plus
-  ``%r`` but only for user-defined instances. Modifiers such as conversion
-  flags, precision, length etc. are not supported. Moreover, it is forbidden
-  to mix unicode and strings when formatting.
-
-**tuples**
-
-  no variable-length tuples; use them to store or return pairs or n-tuples of
-  values. Each combination of types for elements and length constitute
-  a separate and not mixable type.
-
-**lists**
-
-  lists are used as an allocated array.  Lists are over-allocated, so list.append()
-  is reasonably fast. However, if you use a fixed-size list, the code
-  is more efficient. Annotator can figure out most of the time that your
-  list is fixed-size, even when you use list comprehension.
-  Negative or out-of-bound indexes are only allowed for the
-  most common operations, as follows:
-
-  - *indexing*:
-    positive and negative indexes are allowed. Indexes are checked when requested
-    by an IndexError exception clause.
-  
-  - *slicing*:
-    the slice start must be within bounds. The stop doesn't need to, but it must
-    not be smaller than the start.  All negative indexes are disallowed, except for
-    the [:-1] special case.  No step.  Slice deletion follows the same rules.
-    
-  - *slice assignment*:
-    only supports ``lst[x:y] = sublist``, if ``len(sublist) == y - x``.
-    In other words, slice assignment cannot change the total length of the list,
-    but just replace items.
-
-  - *other operators*:
-    ``+``, ``+=``, ``in``, ``*``, ``*=``, ``==``, ``!=`` work as expected.
-
-  - *methods*:
-    append, index, insert, extend, reverse, pop.  The index used in pop() follows
-    the same rules as for *indexing* above.  The index used in insert() must be within
-    bounds and not negative.
-
-**dicts**
-
-  dicts with a unique key type only, provided it is hashable. Custom
-  hash functions and custom equality will not be honored.
-  Use ``rpython.rlib.objectmodel.r_dict`` for custom hash functions.
-
-
-**list comprehensions**
-
-  May be used to create allocated, initialized arrays.
-
-**functions**
-
-+ statically called functions may use defaults and a variable number of
-  arguments (which may be passed as a list instead of a tuple, so write code
-  that does not depend on it being a tuple).
-
-+ dynamic dispatch enforces the use of signatures that are equal for all
-  possible called function, or at least "compatible enough".  This
-  concerns mainly method calls, when the method is overridden or in any
-  way given different definitions in different classes.  It also concerns
-  the less common case of explicitly manipulated function objects.
-  Describing the exact compatibility rules is rather involved (but if you
-  break them, you should get explicit errors from the rtyper and not
-  obscure crashes.)
-
-**builtin functions**
-
-  A number of builtin functions can be used.  The precise set can be
-  found in `rpython/annotator/builtin.py`_ (see ``def builtin_xxx()``).
-  Some builtin functions may be limited in what they support, though.
-
-  ``int, float, str, ord, chr``... are available as simple conversion
-  functions.  Note that ``int, float, str``... have a special meaning as
-  a type inside of isinstance only.
-
-**classes**
-
-+ methods and other class attributes do not change after startup
-+ single inheritance is fully supported
-+ simple mixins work too, but the mixed in class needs a ``_mixin_ = True``
-  class attribute
-
-+ classes are first-class objects too
-
-**objects**
-
-  Normal rules apply. Special methods are not honoured, except ``__init__``,
-  ``__del__`` and ``__iter__``.
-
-This layout makes the number of types to take care about quite limited.
-
-
-Integer Types
--------------------------
-
-While implementing the integer type, we stumbled over the problem that
-integers are quite in flux in CPython right now. Starting with Python 2.4,
-integers mutate into longs on overflow.  In contrast, we need
-a way to perform wrap-around machine-sized arithmetic by default, while still
-being able to check for overflow when we need it explicitly.  Moreover, we need
-a consistent behavior before and after translation.
-
-We use normal integers for signed arithmetic.  It means that before
-translation we get longs in case of overflow, and after translation we get a
-silent wrap-around.  Whenever we need more control, we use the following
-helpers (which live in `rpython/rlib/rarithmetic.py`_):
-
-**ovfcheck()**
-
-  This special function should only be used with a single arithmetic operation
-  as its argument, e.g. ``z = ovfcheck(x+y)``.  Its intended meaning is to
-  perform the given operation in overflow-checking mode.
-
-  At run-time, in Python, the ovfcheck() function itself checks the result
-  and raises OverflowError if it is a ``long``.  But the code generators use
-  ovfcheck() as a hint: they replace the whole ``ovfcheck(x+y)`` expression
-  with a single overflow-checking addition in C.
-
-**intmask()**
-
-  This function is used for wrap-around arithmetic.  It returns the lower bits
-  of its argument, masking away anything that doesn't fit in a C "signed long int".
-  Its purpose is, in Python, to convert from a Python ``long`` that resulted from a
-  previous operation back to a Python ``int``.  The code generators ignore
-  intmask() entirely, as they are doing wrap-around signed arithmetic all the time
-  by default anyway.  (We have no equivalent of the "int" versus "long int"
-  distinction of C at the moment and assume "long ints" everywhere.)
-
-**r_uint**
-
-  In a few cases (e.g. hash table manipulation), we need machine-sized unsigned
-  arithmetic.  For these cases there is the r_uint class, which is a pure
-  Python implementation of word-sized unsigned integers that silently wrap
-  around.  ("word-sized" and "machine-sized" are used equivalently and mean
-  the native size, which you get using "unsigned long" in C.)
-  The purpose of this class (as opposed to helper functions as above)
-  is consistent typing: both Python and the annotator will propagate r_uint
-  instances in the program and interpret all the operations between them as
-  unsigned.  Instances of r_uint are special-cased by the code generators to
-  use the appropriate low-level type and operations.
-  Mixing of (signed) integers and r_uint in operations produces r_uint that
-  means unsigned results.  To convert back from r_uint to signed integers, use
-  intmask().
-

-Exception rules
----------------------
-
-Exceptions are by default not generated for simple cases.::
-
-    #!/usr/bin/python
-
-        lst = [1,2,3,4,5]
-        item = lst[i]    # this code is not checked for out-of-bound access
-
-        try:
-            item = lst[i]
-        except IndexError:
-            # complain
-
-Code with no exception handlers does not raise exceptions (after it has been
-translated, that is.  When you run it on top of CPython, it may raise
-exceptions, of course). By supplying an exception handler, you ask for error
-checking. Without, you assure the system that the operation cannot fail.
-This rule does not apply to *function calls*: any called function is
-assumed to be allowed to raise any exception.
-
-For example::
-
-    x = 5.1
-    x = x + 1.2       # not checked for float overflow
-    try:
-        x = x + 1.2
-    except OverflowError:
-        # float result too big
-
-But::
-
-    z = some_function(x, y)    # can raise any exception
-    try:
-        z = some_other_function(x, y)
-    except IndexError:
-        # only catches explicitly-raised IndexErrors in some_other_function()
-        # other exceptions can be raised, too, and will not be caught here.
-
-The ovfcheck() function described above follows the same rule: in case of
-overflow, it explicitly raise OverflowError, which can be caught anywhere.
-
-Exceptions explicitly raised or re-raised will always be generated.
-
-PyPy is debuggable on top of CPython
-------------------------------------
-
-PyPy has the advantage that it is runnable on standard
-CPython.  That means, we can run all of PyPy with all exception
-handling enabled, so we might catch cases where we failed to
-adhere to our implicit assertions.

+RPython
+=======
+
+RPython Definition
+------------------
+
+RPython is a restricted subset of Python that is amenable to static analysis.
+Although there are additions to the language and some things might surprisingly
+work, this is a rough list of restrictions that should be considered. Note
+that there are tons of special cased restrictions that you'll encounter
+as you go. The exact definition is "RPython is everything that our translation
+toolchain can accept" :)
+
+
+Flow restrictions
+-------------------------
+
+**variables**
+
+  variables should contain values of at most one type as described in
+  `Object restrictions`_ at each control flow point, that means for
+  example that joining control paths using the same variable to
+  contain both a string and a int must be avoided.  It is allowed to
+  mix None (basically with the role of a null pointer) with many other
+  types: wrapped objects, class instances, lists, dicts, strings, etc.
+  but *not* with int, floats or tuples.
+
+**constants**
+
+  all module globals are considered constants.  Their binding must not
+  be changed at run-time.  Moreover, global (i.e. prebuilt) lists and
+  dictionaries are supposed to be immutable: modifying e.g. a global
+  list will give inconsistent results.  However, global instances don't
+  have this restriction, so if you need mutable global state, store it
+  in the attributes of some prebuilt singleton instance.
+
+**control structures**
+
+  all allowed, ``for`` loops restricted to builtin types, generators
+  very restricted.
+
+**range**
+
+  ``range`` and ``xrange`` are identical. ``range`` does not necessarily create an array,
+  only if the result is modified. It is allowed everywhere and completely
+  implemented. The only visible difference to CPython is the inaccessibility
+  of the ``xrange`` fields start, stop and step.
+
+**definitions**
+
+  run-time definition of classes or functions is not allowed.
+
+**generators**
+
+  generators are supported, but their exact scope is very limited. you can't
+  merge two different generator in one control point.
+
+**exceptions**
+
++ fully supported
++ see below `Exception rules`_ for restrictions on exceptions raised by built-in operations
+
+
+Object restrictions
+-------------------------
+
+We are using
+
+**integer, float, boolean**
+
+  works.
+
+**strings**
+
+  a lot of, but not all string methods are supported and those that are
+  supported, not necesarilly accept all arguments.  Indexes can be
+  negative.  In case they are not, then you get slightly more efficient
+  code if the translator can prove that they are non-negative.  When
+  slicing a string it is necessary to prove that the slice start and
+  stop indexes are non-negative. There is no implicit str-to-unicode cast
+  anywhere. Simple string formatting using the ``%`` operator works, as long
+  as the format string is known at translation time; the only supported
+  formatting specifiers are ``%s``, ``%d``, ``%x``, ``%o``, ``%f``, plus
+  ``%r`` but only for user-defined instances. Modifiers such as conversion
+  flags, precision, length etc. are not supported. Moreover, it is forbidden
+  to mix unicode and strings when formatting.
+
+**tuples**
+
+  no variable-length tuples; use them to store or return pairs or n-tuples of
+  values. Each combination of types for elements and length constitute
+  a separate and not mixable type.
+
+**lists**
+
+  lists are used as an allocated array.  Lists are over-allocated, so list.append()
+  is reasonably fast. However, if you use a fixed-size list, the code
+  is more efficient. Annotator can figure out most of the time that your
+  list is fixed-size, even when you use list comprehension.
+  Negative or out-of-bound indexes are only allowed for the
+  most common operations, as follows:
+
+  - *indexing*:
+    positive and negative indexes are allowed. Indexes are checked when requested
+    by an IndexError exception clause.
+  
+  - *slicing*:
+    the slice start must be within bounds. The stop doesn't need to, but it must
+    not be smaller than the start.  All negative indexes are disallowed, except for
+    the [:-1] special case.  No step.  Slice deletion follows the same rules.
+    
+  - *slice assignment*:
+    only supports ``lst[x:y] = sublist``, if ``len(sublist) == y - x``.
+    In other words, slice assignment cannot change the total length of the list,
+    but just replace items.
+
+  - *other operators*:
+    ``+``, ``+=``, ``in``, ``*``, ``*=``, ``==``, ``!=`` work as expected.
+
+  - *methods*:
+    append, index, insert, extend, reverse, pop.  The index used in pop() follows
+    the same rules as for *indexing* above.  The index used in insert() must be within
+    bounds and not negative.
+
+**dicts**
+
+  dicts with a unique key type only, provided it is hashable. Custom
+  hash functions and custom equality will not be honored.
+  Use ``rpython.rlib.objectmodel.r_dict`` for custom hash functions.
+
+**list comprehensions**
+
+  May be used to create allocated, initialized arrays.
+
+**functions**
+
++ statically called functions may use defaults and a variable number of
+  arguments (which may be passed as a list instead of a tuple, so write code
+  that does not depend on it being a tuple).
+
++ dynamic dispatch enforces the use of signatures that are equal for all
+  possible called function, or at least "compatible enough".  This
+  concerns mainly method calls, when the method is overridden or in any
+  way given different definitions in different classes.  It also concerns
+  the less common case of explicitly manipulated function objects.
+  Describing the exact compatibility rules is rather involved (but if you
+  break them, you should get explicit errors from the rtyper and not
+  obscure crashes.)
+
+**builtin functions**
+
+  A number of builtin functions can be used.  The precise set can be
+  found in `rpython/annotator/builtin.py`_ (see ``def builtin_xxx()``).
+  Some builtin functions may be limited in what they support, though.
+
+  ``int, float, str, ord, chr``... are available as simple conversion
+  functions.  Note that ``int, float, str``... have a special meaning as
+  a type inside of isinstance only.
+
+**classes**
+
++ methods and other class attributes do not change after startup
++ single inheritance is fully supported
++ simple mixins work too, but the mixed in class needs a ``_mixin_ = True``
+  class attribute
+
++ classes are first-class objects too
+
+**objects**
+
+  Normal rules apply. Special methods are not honoured, except ``__init__``,
+  ``__del__`` and ``__iter__``.
+
+This layout makes the number of types to take care about quite limited.
+
+
+Integer Types
+-------------------------
+
+While implementing the integer type, we stumbled over the problem that
+integers are quite in flux in CPython right now. Starting with Python 2.4,
+integers mutate into longs on overflow.  In contrast, we need
+a way to perform wrap-around machine-sized arithmetic by default, while still
+being able to check for overflow when we need it explicitly.  Moreover, we need
+a consistent behavior before and after translation.
+
+We use normal integers for signed arithmetic.  It means that before
+translation we get longs in case of overflow, and after translation we get a
+silent wrap-around.  Whenever we need more control, we use the following
+helpers (which live in `rpython/rlib/rarithmetic.py`_):
+
+**ovfcheck()**
+
+  This special function should only be used with a single arithmetic operation
+  as its argument, e.g. ``z = ovfcheck(x+y)``.  Its intended meaning is to
+  perform the given operation in overflow-checking mode.
+
+  At run-time, in Python, the ovfcheck() function itself checks the result
+  and raises OverflowError if it is a ``long``.  But the code generators use
+  ovfcheck() as a hint: they replace the whole ``ovfcheck(x+y)`` expression
+  with a single overflow-checking addition in C.
+
+**intmask()**
+
+  This function is used for wrap-around arithmetic.  It returns the lower bits
+  of its argument, masking away anything that doesn't fit in a C "signed long int".
+  Its purpose is, in Python, to convert from a Python ``long`` that resulted from a
+  previous operation back to a Python ``int``.  The code generators ignore
+  intmask() entirely, as they are doing wrap-around signed arithmetic all the time
+  by default anyway.  (We have no equivalent of the "int" versus "long int"
+  distinction of C at the moment and assume "long ints" everywhere.)
+
+**r_uint**
+
+  In a few cases (e.g. hash table manipulation), we need machine-sized unsigned
+  arithmetic.  For these cases there is the r_uint class, which is a pure
+  Python implementation of word-sized unsigned integers that silently wrap
+  around.  ("word-sized" and "machine-sized" are used equivalently and mean
+  the native size, which you get using "unsigned long" in C.)
+  The purpose of this class (as opposed to helper functions as above)
+  is consistent typing: both Python and the annotator will propagate r_uint
+  instances in the program and interpret all the operations between them as
+  unsigned.  Instances of r_uint are special-cased by the code generators to
+  use the appropriate low-level type and operations.
+  Mixing of (signed) integers and r_uint in operations produces r_uint that
+  means unsigned results.  To convert back from r_uint to signed integers, use
+  intmask().
+
+
+Exception rules
+---------------------
+
+Exceptions are by default not generated for simple cases.::
+
+    #!/usr/bin/python
+
+        lst = [1,2,3,4,5]
+        item = lst[i]    # this code is not checked for out-of-bound access
+
+        try:
+            item = lst[i]
+        except IndexError:
+            # complain
+
+Code with no exception handlers does not raise exceptions (after it has been
+translated, that is.  When you run it on top of CPython, it may raise
+exceptions, of course). By supplying an exception handler, you ask for error
+checking. Without, you assure the system that the operation cannot fail.
+This rule does not apply to *function calls*: any called function is
+assumed to be allowed to raise any exception.
+
+For example::
+
+    x = 5.1
+    x = x + 1.2       # not checked for float overflow
+    try:
+        x = x + 1.2
+    except OverflowError:
+        # float result too big
+
+But::
+
+    z = some_function(x, y)    # can raise any exception
+    try:
+        z = some_other_function(x, y)
+    except IndexError:
+        # only catches explicitly-raised IndexErrors in some_other_function()
+        # other exceptions can be raised, too, and will not be caught here.
+
+The ovfcheck() function described above follows the same rule: in case of
+overflow, it explicitly raise OverflowError, which can be caught anywhere.
+
+Exceptions explicitly raised or re-raised will always be generated.
+
+
+PyPy is debuggable on top of CPython
+------------------------------------
+
+PyPy has the advantage that it is runnable on standard
+CPython.  That means, we can run all of PyPy with all exception
+handling enabled, so we might catch cases where we failed to
+adhere to our implicit assertions.

-The RPython translation tool chain
-===================================
-
-------------------------------------------------
-Can RPython compile normal Python programs to C?
-------------------------------------------------
-
-No, RPython is not a Python compiler.
-
-In Python, it is mostly impossible to *prove* anything about the types
-that a program will manipulate by doing a static analysis.  It should be
-clear if you are familiar with Python, but if in doubt see [BRETT]_.
-
-If you want a fast Python program, please use the PyPy JIT_ instead.
-
-.. _JIT: jit/index.html
-
-.. [BRETT] Brett Cannon,
-           Localized Type Inference of Atomic Types in Python,
-           http://citeseer.ist.psu.edu/viewdoc/summary?doi=10.1.1.90.3231
-
-.. _`PyPy's RPython`: 
-
-------------------------------
-What is this RPython language?
-------------------------------
-
-RPython is a restricted subset of the Python language.   It is used for 
-implementing dynamic language interpreters within the PyPy toolchain.  The
-restrictions ensure that type inference (and so, ultimately, translation
-to other languages) of RPython programs is possible. 
-
-The property of "being RPython" always applies to a full program, not to single
-functions or modules (the translation toolchain does a full program analysis).
-The translation toolchain follows all calls
-recursively and discovers what belongs to the program and what does not.
-
-RPython program restrictions mostly limit the ability
-to mix types in arbitrary ways. RPython does not allow the binding of two
-different types in the same variable. In this respect (and in some others) it
-feels a bit like Java. Other features not allowed in RPython are the use of
-special methods (``__xxx__``) except ``__init__`` and ``__del__``, and the
-use of reflection capabilities (e.g. ``__dict__``).
-
-You cannot use most existing standard library modules from RPython.  The
-exceptions are
-some functions in ``os``, ``math`` and ``time`` that have native support.
-
-To read more about the RPython limitations read the `RPython description`_.
-
-.. _`RPython description`: coding-guide.html#restricted-python
-
----------------------------------------------------------------
-Does RPython have anything to do with Zope's Restricted Python?
----------------------------------------------------------------
-
-No.  `Zope's RestrictedPython`_ aims to provide a sandboxed 
-execution environment for CPython.   `PyPy's RPython`_ is the implementation
-language for dynamic language interpreters.  However, PyPy also provides 
-a robust `sandboxed Python Interpreter`_. 
-
-.. _`sandboxed Python Interpreter`: sandbox.html
-.. _`Zope's RestrictedPython`: http://pypi.python.org/pypi/RestrictedPython
-
-------------------------------------------------------
-What's the ``"NOT_RPYTHON"`` I see in some docstrings?
-------------------------------------------------------
-
-If you put "NOT_RPYTHON" into the docstring of a function and that function is
-found while trying to translate an RPython program, the translation process
-stops and reports this as an error. You can therefore mark functions as
-"NOT_RPYTHON" to make sure that they are never analyzed.
-
-
--------------------------------------------------------------------
-Couldn't we simply take a Python syntax tree and turn it into Lisp?
--------------------------------------------------------------------
-
-It's not necessarily nonsense, but it's not really The PyPy Way.  It's
-pretty hard, without some kind of type inference, to translate this
-Python::
-
-    a + b
-
-into anything significantly more efficient than this Common Lisp::
-
-    (py:add a b)
-
-And making type inference possible is what RPython is all about.
-
-You could make ``#'py:add`` a generic function and see if a given CLOS
-implementation is fast enough to give a useful speed (but I think the
-coercion rules would probably drive you insane first).  -- mwh
-
---------------------------------------------
-Do I have to rewrite my programs in RPython?
---------------------------------------------
-
-No, and you shouldn't try.  First and foremost, RPython is a language
-designed for writing interpreters. It is a restricted subset of
-Python.  If you program is not an interpreter but tries to do "real
-things", like use *any* part of the standard Python library or *any*
-3rd-party library, then it is not RPython to start with.  You should
-only look at RPython if you try to `write your own interpreter`__.
-
-.. __: `how do I compile my own interpreters`_
-
-If your goal is to speed up Python code, then look at the regular PyPy,
-which is a full and compliant Python 2.7 interpreter (which happens to
-be written in RPython).  Not only is it not necessary for you to rewrite
-your code in RPython, it might not give you any speed improvements even
-if you manage to.
-
-Yes, it is possible with enough effort to compile small self-contained
-pieces of RPython code doing a few performance-sensitive things.  But
-this case is not interesting for us.  If you needed to rewrite the code
-in RPython, you could as well have rewritten it in C for example.  The
-latter is a much more supported, much more documented language `:-)`
-
----------------------------------------------------
-Which backends are there for the RPython toolchain?
----------------------------------------------------
-
-Currently, there are backends for C_, the CLI_, and the JVM_.
-All of these can translate the entire PyPy interpreter.
-To learn more about backends take a look at the `translation document`_.
-
-.. _C: translation.html#the-c-back-end
-.. _CLI: cli-backend.html
-.. _JVM: translation.html#genjvm
-.. _`translation document`: translation.html
-
-------------------
-Could we use LLVM?
-------------------
-
-In theory yes.  But we tried to use it 5 or 6 times already, as a
-translation backend or as a JIT backend --- and failed each time.
-
-In more details: using LLVM as a (static) translation backend is
-pointless nowadays because you can generate C code and compile it with
-clang.  (Note that compiling PyPy with clang gives a result that is not
-faster than compiling it with gcc.)  We might in theory get extra
-benefits from LLVM's GC integration, but this requires more work on the
-LLVM side before it would be remotely useful.  Anyway, it could be
-interfaced via a custom primitive in the C code.
-
-On the other hand, using LLVM as our JIT backend looks interesting as
-well --- but again we made an attempt, and it failed: LLVM has no way to
-patch the generated machine code.
-
-So the position of the core PyPy developers is that if anyone wants to
-make an N+1'th attempt with LLVM, he is welcome, and he will receive a
-bit of help on the IRC channel, but he is left with the burden of proof
-that it works.

-
----------------------------------------------------------
-Can RPython modules for PyPy be translated independently?
----------------------------------------------------------
-
-No, you have to rebuild the entire interpreter.  This means two things:
-
-* It is imperative to use test-driven development.  You have to exhaustively
-  test your module in pure Python, before even attempting to
-  translate it.  Once you translate it, you should have only a few typing
-  issues left to fix, but otherwise the result should work out of the box.
-
-* Second, and perhaps most important: do you have a really good reason
-  for writing the module in RPython in the first place?  Nowadays you
-  should really look at alternatives, like writing it in pure Python,
-  using ctypes if it needs to call C code.  Other alternatives are being
-  developed too (as of summer 2011), like a Cython binding.
-
-In this context it is not that important to be able to translate
-RPython modules independently of translating the complete interpreter.
-(It could be done given enough efforts, but it's a really serious
-undertaking.  Consider it as quite unlikely for now.)
-
-----------------------------------------------------------
-Why does PyPy draw a Mandelbrot fractal while translating?
-----------------------------------------------------------
-
-Because it's fun.

-=============================
-lib_pypy/distributed features
-=============================
-
-The 'distributed' library is an attempt to provide transparent, lazy
-access to remote objects. This is accomplished using
-`transparent proxies`_ and in application level code (so as a pure
-python module).
-
-The implementation uses an RPC-like protocol, which accesses
-only members of objects, rather than whole objects. This means it
-does not rely on objects being pickleable, nor on having the same
-source code available on both sides. On each call, only the members
-that are used on the client side are retrieved, objects which
-are not used are merely references to their remote counterparts.
-
-As an example, let's imagine we have a remote object, locally available
-under the name `x`. Now we call::
-
-    >>>> x.foo(1, [1,2,3], y)
-
-where y is some instance of a local, user-created class.
-
-Under water, x.\_\_getattribute\_\_ is called, with argument 'foo'. In the
-\_\_getattribute\_\_ implementation, the 'foo' attribute is requested, and the
-remote side replies by providing a bound method. On the client this bound
-method appears as a remote reference: this reference is called with a remote
-reference to x as self, the integer 1 which is copied as a primitive type, a
-reference to a list and a reference to y. The remote side receives this call,
-processes it as a call to the bound method x.foo, where 'x' is resolved as a
-local object, 1 as an immutable primitive, [1,2,3] as a reference to a mutable
-primitive and y as a reference to a remote object. If the type of y is not
-known on the remote side, it is faked with just about enough shape (XXX?!?) to
-be able to perform the required operations.  The contents of the list are
-retrieved when they're needed.
-
-An advantage of this approach is that a user can have remote references to
-internal interpreter types, like frames, code objects and tracebacks. In a demo
-directory there is an example of using this to attach pdb.post\_mortem() to a
-remote traceback. Another advantage is that there's a minimal amount of data
-transferred over the network. On the other hand, there are a large amount of
-packages sent to the remote side - hopefully this will be improved in future.
-
-The 'distributed' lib is uses an abstract network layer, which means you
-can provide custom communication channels just by implementing
-two functions that send and receive marshallable objects (no pickle needed!).
-
-Exact rules of copying
-----------------------
-
-- Immutable primitives are always transferred
-
-- Mutable primitives are transferred as a reference, but several operations
-  (like iter()) force them to be transferred fully
-
-- Builtin exceptions are transferred by name
-
-- User objects are always faked on the other side, with enough shape
-  transferred
-
-XXX finish, basic interface, example, build some stuff on top of greenlets
-
-Related work comparison
------------------------
-
-There are a lot of attempts to incorporate RPC mechanism into
-Python, some of them are listed below:
-
-* `Pyro`_ - Pyro stands for PYthon Remote Objects, it's a mechanism of
-  implementing remotely accessible objects in pure python (without modifying
-  interpreter). This is only a remote method call implementation, with
-  all limitations, so:
-
-  - No attribute access
-
-  - Arguments of calls must be pickleable on one side and unpickleable on
-    remote side, which means they must share source code, they do not
-    become remote references
-
-  - Exported objects must inherit from specific class and follow certain
-    standards, like \_\_init\_\_ shape.
-
-  - Remote tracebacks only as strings
-
-  - Remote calls usually invokes new threads
-
-* XMLRPC - There are several implementations of xmlrpc protocol in Python,
-  one even in the standard library. Xmlrpc is cross-language, cross-platform
-  protocol of communication, which implies great flexibility of tools to
-  choose, but also implies several limitations, like:
-
-  - No remote tracebacks
-
-  - Only simple types to be passed as function arguments
-
-* Twisted Perspective Broker
-
-  - involves twisted, which ties user to network stack/programming style
-
-  - event driven programming (might be good, might be bad, but it's fixed)
-
-  - copies object (by pickling), but provides sophisticated layer of
-    caching to avoid multiple copies of the same object.
-
-  - two way RPC (unlike Pyro)
-
-  - also heavy restrictions on objects - they must subclass certain class

-     or not.  Assumes no partial sharing in the chained lists.  Works by
-     trying to search forward with S1, starting from G1, if it reaches
-     G2; and conversely with S2, starting from G2, if it reaches G1. */
-  gcptr S1 = G1, S2 = G2;
+  /* This is a mess, because G1 and G2 can be different pointers to "the
+     same" object, and it's hard to determine that.  Description of the
+     idealized problem: we have chained lists following the 'h_revision'
+     field from G1 and from G2, and we must return True if the chained
+     lists end in the same object G and False if they don't.
+
+     It's possible that G1 != G2 but G1->h_revision == G2->h_revision.
+     This occurs because of random updates done by PossiblyUpdateChain().
+
+     But the real mess comes from other threads doing concurrent
+     updates.  They can be either done by PossiblyUpdateChain() from
+     other threads, changing 'h_revision' without warning to point to
+     what used to be 'h_revision-> ... -> h_revision'.  Alternatively,
+     they can be adding new objects to the so-far root of the tree:
+     consider the G that used to be the end of both chained lists.  Its
+     'h_revision' used to be not-a-pointer.  But it can suddenly
+     suddenly turns into a LOCK value, and then later to a pointer to
+     some new object, making the chained list longer.  Worse, once the
+     list is longer, a PossiblyUpdateChain() might make shortcuts in
+     it...
+
+     So it means even the following algorithm is flawed: "follow
+     h_revisions from G1 until we reach G; then follow h_revisions from
+     G2, and return True/False if we reach/do not reach the same G".
+
+     For now we go with: try to move forward G1 and G2 alternatively,
+     until we failed three times to move forward one of these.  Let's
+     say the last three steps were "G1 is already at the end", "G2 is
+     already at the end", "G1 is already at the end".  Then we can
+     return (G1 == G2).  This is because we know that G1 was at the end
+     of the chained list for the whole time during which we checked G2.

+     WARNING: THIS ONLY WORKS ON THE X86 MEMORY MODEL, AND NOT ON WEAKER

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the

+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

Log:	Merge kill-flowobjspace (ronan):

	This is a basically just a bunch of random cleanups. Despite the
	name, it doesn't kill FlowObjSpace, but it does hide it from public
	view.

	Highlights:

	 replaces FlowObjSpace().build_flow(func) with just
	build_flow(func)

	 cleans up the ArgumentsForTranslation mess in flowspace

	 moves ArgumentsForTranslation to rpython.annotator, since it's
	not used in flowspace any more

+   On these operating systems, nl_langinfo(CODESET) announces an alias of the
+   ASCII encoding, whereas mbstowcs() and wcstombs() functions use the
+   ISO-8859-1 encoding. The problem is that os.fsencode() and os.fsdecode() use
+   locale.getpreferredencoding() codec. For example, if command line arguments
+   are decoded by mbstowcs() and encoded back by os.fsencode(), we get a
+   UnicodeEncodeError instead of retrieving the original byte string.
+
+   The workaround is enabled if setlocale(LC_CTYPE, NULL) returns "C",
+   nl_langinfo(CODESET) announces "ascii" (or an alias to ASCII), and at least
+   one byte in range 0x80-0xff can be decoded from the locale encoding. The
+   workaround is also enabled on error, for example if getting the locale
+   failed.
+
+   Values of locale_is_ascii:
+
+       1: the workaround is used: _Py_wchar2char() uses
+          encode_ascii_surrogateescape() and _Py_char2wchar() uses

Log:	Change the hack: instead of passing None for NULL pointers, we pass
	0. This is more compatible with C. Also accept 0 at other places
	that expect a pointer.

+"From a software engineering perspective, 10 years is indistinguishable
+from infinity, so I don't care what happens 10 years from now -- as
+long as you don't blame me. :-)" - Guido van Rossum, Python creator.
+
+10 years is indeed a long time. PyPy was created approximately 10 years ago,
+with the exact date being lost in the annals of the version control system.
+We've come a long way during those 10 years, from a "minimal Python" that
+was supposed to serve mostly as an educational tool, through to a vehicle for
+academic research to a high performance VM for Python and beyond.
+
+Some facts from the PyPy timeline:
+
+* In 2007, at the end of the EU funding period, we promised the JIT was just around the corner.
+  It turned out we misjudged it pretty badly -- the first usable PyPy was released in 2010.
+
+* At some point we decided to have a JavaScript backend so one could compile RPython programs
+  to JavaScript and run them in a browser. Turned out it was a horrible idea.
+
+* Another option for using RPython was to write CPython C extensions. Again, turned out RPython
+  is a bad language and instead we made a fast JIT, so you don't have to write C extensions.
+
+* We made N attempts to use LLVM.  Seriously, N is 4 or 5.  But we haven't fully given up yet :-)
+  They all run into issues one way or another.
+
+* We were huge fans of ctypes from the beginning. Up to the point where we tried to make
+  a restricted subset with static types, called rctypes for RPython. Turned out to be horrible.
+  Twice.
+
+* We were very hopeful about JIT generator from the beginning. But the first one failed miserably,
+  generating too much assembler. The second failed too. The third first burned down and then failed.
+  However, we managed to release a working JIT in 2010, against all odds.
+
+* Martijn Faassen used to ask us "how fast is PyPy" so we decided to name an option enabling all
+  optimizations --faassen. --no-faassen was added automatically doing nothing. Then we
+  decided to grow up and renamed it to -O2 and -Ojit.
+
+Cheers,
+fijal, arigo and the pypy team.

+* At one sprint someone proposed a new software development methodology: 'Terminology-Driven Programming' means to pick a fancy name, then discuss what it could mean, then implement it. Examples: timeshifter, rainbow interpreter, meta-space bubble, hint annotations (all but one of these really existed).
+
+* There is a conspiracy theory that the reason why translation is so slow is because time is stored away during it, which is later retrieved when an actual program runs to make them appear faster
+
 Overall, it was a really long road.  However, 10 years later we are in
 good shape.  A quick look on the immediate future: we are approaching
-PyPy 2.0, the support for Python 3 is taking shape, non-standard
+PyPy 2.0 with stackless+JIT and cffi support,
+the support for Python 3 is taking shape, non-standard
 extensions like STM are slowly getting ready (more soon), and there are
-several non-Python interpreters around the corner (Topaz and more).
