When the dialect argument is a string, -it identifies one of the dialects previously registered with the module. -If it is a class or instance, the attributes of the argument are used as -the settings for the reader or writer: - - class excel: - delimiter = ',' - quotechar = '\"' - escapechar = None - doublequote = True - skipinitialspace = False - lineterminator = '\\r\\n' - quoting = QUOTE_MINIMAL - -SETTINGS: - - * quotechar - specifies a one-character string to use as the - quoting character. It defaults to '\"'. - * delimiter - specifies a one-character string to use as the - field separator. It defaults to ','. - * skipinitialspace - specifies how to interpret whitespace which - immediately follows a delimiter. It defaults to False, which - means that whitespace immediately following a delimiter is part - of the following field. - * lineterminator - specifies the character sequence which should - terminate rows. - * quoting - controls when quotes should be generated by the writer. - It can take on any of the following module constants: - - csv.QUOTE_MINIMAL means only when required, for example, when a - field contains either the quotechar or the delimiter - csv.QUOTE_ALL means that quotes are always placed around fields. - csv.QUOTE_NONNUMERIC means that quotes are always placed around - fields which do not parse as integers or floating point - numbers. - csv.QUOTE_NONE means that quotes are never placed around fields. - * escapechar - specifies a one-character string used to escape - the delimiter when quoting is set to QUOTE_NONE. - * doublequote - controls the handling of quotes inside fields. When - True, two consecutive quotes are interpreted as one during read, - and when writing, each quote character embedded in the data is - written as two quotes. -""" - -__version__ = "1.0" - -QUOTE_MINIMAL, QUOTE_ALL, QUOTE_NONNUMERIC, QUOTE_NONE = range(4) -_dialects = {} -_field_limit = 128 * 1024 # max parsed field size -

-What's new in PyPy2.7 5.10+
-===========================
-
-.. this is a revision shortly after release-pypy2.7-v5.10.0
-.. startrev: 6b024edd9d12
-
-.. branch: cpyext-avoid-roundtrip
-
-Big refactoring of some cpyext code, which avoids a lot of nonsense when
-calling C from Python and vice-versa: the result is a big speedup in
-function/method calls, up to 6 times faster.
-
-.. branch: cpyext-datetime2
-
-Support ``tzinfo`` field on C-API datetime objects, fixes latest pandas HEAD
-
-
-.. branch: mapdict-size-limit
-
-Fix a corner case of mapdict: When an instance is used like a dict (using
-``setattr`` and ``getattr``, or ``.__dict__``) and a lot of attributes are
-added, then the performance using mapdict is linear in the number of
-attributes. This is now fixed (by switching to a regular dict after 80
-attributes).
-
-
-.. branch: cpyext-faster-arg-passing
-
-When using cpyext, improve the speed of passing certain objects from PyPy to C
-code, most notably None, True, False, types, all instances of C-defined types.
-Before, a dict lookup was needed every time such an object crossed over, now it
-is just a field read.
-
-
-.. branch: 2634_datetime_timedelta_performance
-
-Improve datetime + timedelta performance.
-
-.. branch: memory-accounting
-
-Improve way to describe memory
-
-.. branch: msvc14
-
-Allow compilaiton with Visual Studio 2017 compiler suite on windows
-
-.. branch: winapi
-
-Update _winapi and internal _winbase_cffi (via _winbase_build) for python 3 
-
-.. branch: refactor-slots
-
-Refactor cpyext slots.
-
-
-.. branch: call-loopinvariant-into-bridges
-
-Speed up branchy code that does a lot of function inlining by saving one call
-to read the TLS in most bridges.
-
-.. branch: rpython-sprint
-
-Refactor in rpython signatures
-
-.. branch: cpyext-tls-operror2
-
-Store error state thread-locally in executioncontext, fixes issue #2764
-
-.. branch: cpyext-fast-typecheck
-
-Optimize `Py*_Check` for `Bool`, `Float`, `Set`. Also refactor and simplify
-`W_PyCWrapperObject` which is used to call slots from the C-API, greatly
-improving microbenchmarks in https://github.com/antocuni/cpyext-benchmarks
-
-
-.. branch: fix-sre-problems
-
-Fix two (unrelated) JIT bugs manifesting in the re module:
-
-- green fields are broken and were thus disabled, plus their usage removed from
-  the _sre implementation
-
-- in rare "trace is too long" situations, the JIT could break behaviour
-  arbitrarily.
-
-.. branch: jit-hooks-can-be-disabled
-
-Be more efficient about JIT hooks. Make it possible for the frontend to declare
-that jit hooks are currently not enabled at all. in that case, the list of ops
-does not have to be created in the case of the on_abort hook (which is
-expensive).
-
-
-.. branch: pyparser-improvements
-
-Improve speed of Python parser, improve ParseError messages slightly.
-
-.. branch: ioctl-arg-size
-
-Work around possible bugs in upstream ioctl users, like CPython allocate at
-least 1024 bytes for the arg in calls to ``ioctl(fd, request, arg)``. Fixes
-issue #2776
-
-.. branch: cpyext-subclass-setattr
-
-Fix for python-level classes that inherit from C-API types, previously the
-`w_obj` was not necessarily preserved throughout the lifetime of the `pyobj`
-which led to cases where instance attributes were lost. Fixes issue #2793
-
-
-.. branch: pyparser-improvements-2
-
-Improve line offsets that are reported by SyntaxError. Improve error messages
-for a few situations, including mismatched parenthesis.

+
+Speed up branchy code that does a lot of function inlining by saving one call
+to read the TLS in most bridges.
+
+.. branch: rpython-sprint
+
+Refactor in rpython signatures
+
+.. branch: cpyext-tls-operror2
+
+Store error state thread-locally in executioncontext, fixes issue #2764
+
+.. branch: cpyext-fast-typecheck
+
+Optimize `Py*_Check` for `Bool`, `Float`, `Set`. Also refactor and simplify
+`W_PyCWrapperObject` which is used to call slots from the C-API, greatly
+improving microbenchmarks in https://github.com/antocuni/cpyext-benchmarks
+
+
+.. branch: fix-sre-problems
+
+Fix two (unrelated) JIT bugs manifesting in the re module:
+
+- green fields are broken and were thus disabled, plus their usage removed from
+  the _sre implementation
+
+- in rare "trace is too long" situations, the JIT could break behaviour
+  arbitrarily.
+
+.. branch: jit-hooks-can-be-disabled
+
+Be more efficient about JIT hooks. Make it possible for the frontend to declare
+that jit hooks are currently not enabled at all. in that case, the list of ops
+does not have to be created in the case of the on_abort hook (which is
+expensive).
+
+
+.. branch: pyparser-improvements
+
+Improve speed of Python parser, improve ParseError messages slightly.
+
+.. branch: ioctl-arg-size
+
+Work around possible bugs in upstream ioctl users, like CPython allocate at
+least 1024 bytes for the arg in calls to ``ioctl(fd, request, arg)``. Fixes
+issue #2776
+
+.. branch: cpyext-subclass-setattr
+
+Fix for python-level classes that inherit from C-API types, previously the
+`w_obj` was not necessarily preserved throughout the lifetime of the `pyobj`
+which led to cases where instance attributes were lost. Fixes issue #2793
+
+
+.. branch: pyparser-improvements-2
+
+Improve line offsets that are reported by SyntaxError. Improve error messages
+for a few situations, including mismatched parenthesis.
+
+.. branch: issue2752
+
+Fix a rare GC bug that was introduced more than one year ago, but was
+not diagnosed before issue #2752.
+
+.. branch: gc-hooks
+
+Introduce GC hooks, as documented in doc/gc_info.rst
+
+.. branch: gc-hook-better-timestamp
+
+Improve GC hooks
+
+.. branch: cppyy-packaging
+
+Update backend to 0.6.0 and support exceptions through wrappers

    the same works for the other two macros.  Py_DEBUG implies them,
    but not the other way around.
 
-   The implementation is messy (issue #350): on Windows, with _MSC_VER,
-   we have to define Py_LIMITED_API even before including pyconfig.h.
-   In that case, we guess what pyconfig.h will do to the macros above,
-   and check our guess after the #include.
-
-   Note that on Windows, with CPython 3.x, you need virtualenv version
-   >= 16.0.0.  Older versions don't copy PYTHON3.DLL.  As a workaround
-   you can remove the definition of Py_LIMITED_API here.
-
-   See also 'py_limited_api' in cffi/setuptools_ext.py.
+   Issue #350 is still open: on Windows, the code here causes it to link
+   with PYTHON36.DLL (for example) instead of PYTHON3.DLL.  A fix was
+   attempted in 164e526a5515 and 14ce6985e1c3, but reverted: virtualenv
+   does not make PYTHON3.DLL available, and so the "correctly" compiled
+   version would not run inside a virtualenv.  We will re-apply the fix
+   after virtualenv has been fixed for some time.  For explanation, see
+   issue #355.  For a workaround if you want PYTHON3.DLL and don't worry
+   about virtualenv, see issue #350.  See also 'py_limited_api' in

    the same works for the other two macros.  Py_DEBUG implies them,
    but not the other way around.
 
-   The implementation is messy (issue #350): on Windows, with _MSC_VER,
-   we have to define Py_LIMITED_API even before including pyconfig.h.
-   In that case, we guess what pyconfig.h will do to the macros above,
-   and check our guess after the #include.
-
-   Note that on Windows, with CPython 3.x, you need virtualenv version
-   >= 16.0.0.  Older versions don't copy PYTHON3.DLL.  As a workaround
-   you can remove the definition of Py_LIMITED_API here.
-
-   See also 'py_limited_api' in cffi/setuptools_ext.py.
+   Issue #350 is still open: on Windows, the code here causes it to link
+   with PYTHON36.DLL (for example) instead of PYTHON3.DLL.  A fix was
+   attempted in 164e526a5515 and 14ce6985e1c3, but reverted: virtualenv
+   does not make PYTHON3.DLL available, and so the "correctly" compiled
+   version would not run inside a virtualenv.  We will re-apply the fix
+   after virtualenv has been fixed for some time.  For explanation, see
+   issue #355.  For a workaround if you want PYTHON3.DLL and don't worry
+   about virtualenv, see issue #350.  See also 'py_limited_api' in
+   setuptools_ext.py.

    the same works for the other two macros.  Py_DEBUG implies them,
    but not the other way around.
 
-   The implementation is messy (issue #350): on Windows, with _MSC_VER,
-   we have to define Py_LIMITED_API even before including pyconfig.h.
-   In that case, we guess what pyconfig.h will do to the macros above,
-   and check our guess after the #include.
-
-   Note that on Windows, with CPython 3.x, you need virtualenv version
-   >= 16.0.0.  Older versions don't copy PYTHON3.DLL.  As a workaround
-   you can remove the definition of Py_LIMITED_API here.
-
-   See also 'py_limited_api' in cffi/setuptools_ext.py.
+   Issue #350 is still open: on Windows, the code here causes it to link
+   with PYTHON36.DLL (for example) instead of PYTHON3.DLL.  A fix was
+   attempted in 164e526a5515 and 14ce6985e1c3, but reverted: virtualenv
+   does not make PYTHON3.DLL available, and so the "correctly" compiled
+   version would not run inside a virtualenv.  We will re-apply the fix
+   after virtualenv has been fixed for some time.  For explanation, see
+   issue #355.  For a workaround if you want PYTHON3.DLL and don't worry

-determine which block you are in.  This extension implements a pane at the top
-of each IDLE edit window which provides block structure hints.  These hints are
-the lines which contain the block opening keywords, e.g. 'if', for the
-enclosing block.  The number of hint lines is determined by the numlines
-variable in the codecontext section of config-extensions.def. Lines which do
-not open blocks are not shown in the context hints pane.

+# A private copy of 3.7.0a1 pyclbr for use by idlelib.browser
+"""Parse a Python module and describe its classes and functions.
+
+Parse enough of a Python file to recognize imports and class and
+function definitions, and to find out the superclasses of a class.
+
+The interface consists of a single function:
+    readmodule_ex(module, path=None)
+where module is the name of a Python module, and path is an optional
+list of directories where the module is to be searched.  If present,
+path is prepended to the system search path sys.path.  The return value
+is a dictionary.  The keys of the dictionary are the names of the
+classes and functions defined in the module (including classes that are
+defined via the from XXX import YYY construct).  The values are
+instances of classes Class and Function.  One special key/value pair is
+present for packages: the key '__path__' has a list as its value which
+contains the package search path.
+
+Classes and Functions have a common superclass: _Object.  Every instance
+has the following attributes:
+    module  -- name of the module;
+    name    -- name of the object;
+    file    -- file in which the object is defined;
+    lineno  -- line in the file where the object's definition starts;
+    parent  -- parent of this object, if any;
+    children -- nested objects contained in this object.
+The 'children' attribute is a dictionary mapping names to objects.
+
+Instances of Function describe functions with the attributes from _Object.
+
+Instances of Class describe classes with the attributes from _Object,
+plus the following:
+    super   -- list of super classes (Class instances if possible);
+    methods -- mapping of method names to beginning line numbers.
+If the name of a super class is not recognized, the corresponding
+entry in the list of super classes is not a class instance but a
+string giving the name of the super class.  Since import statements
+are recognized and imported modules are scanned as well, this
+shouldn't happen often.

    the same works for the other two macros.  Py_DEBUG implies them,
    but not the other way around.
 
-   The implementation is messy (issue #350): on Windows, with _MSC_VER,
-   we have to define Py_LIMITED_API even before including pyconfig.h.
-   In that case, we guess what pyconfig.h will do to the macros above,
-   and check our guess after the #include.
-
-   Note that on Windows, with CPython 3.x, you need virtualenv version
-   >= 16.0.0.  Older versions don't copy PYTHON3.DLL.  As a workaround
-   you can remove the definition of Py_LIMITED_API here.
-
-   See also 'py_limited_api' in cffi/setuptools_ext.py.
+   Issue #350 is still open: on Windows, the code here causes it to link
+   with PYTHON36.DLL (for example) instead of PYTHON3.DLL.  A fix was
+   attempted in 164e526a5515 and 14ce6985e1c3, but reverted: virtualenv
+   does not make PYTHON3.DLL available, and so the "correctly" compiled
+   version would not run inside a virtualenv.  We will re-apply the fix
+   after virtualenv has been fixed for some time.  For explanation, see
+   issue #355.  For a workaround if you want PYTHON3.DLL and don't worry
+   about virtualenv, see issue #350.  See also 'py_limited_api' in

 Here are a few examples of where buffer() would be useful:
 
 -  use ``file.write()`` and ``file.readinto()`` with
    such a buffer (for files opened in binary mode)
 
--  use ``ffi.buffer(mystruct[0])[:] = socket.recv(len(buffer))`` to read

+-  overwrite the content of a struct: if ``p`` is a cdata pointing to
+   it, use ``ffi.buffer(p)[:] = newcontent``, where ``newcontent`` is
+   a bytes object (``str`` in Python 2).
 
 Remember that like in C, you can use ``array + index`` to get the pointer
 to the index'th item of an array.  (In C you might more naturally write
 ``&array[index]``, but that is equivalent.)
