[C++-sig] Bugs with Pyste and vector_indexing_suite.

[Prabhu Ramachandran]

Hi,

Three bugs.

  1. The issue with vector_indexing_suite and exposing
     std::vector<bool> still remains.  I've patched my local copy with
     the fix that Joel posted but this is not yet in CVS.  Would
     appreciate if this could be fixed in CVS.  Thanks!

  2. Pyste from CVS has problems I have not had the time to track it
     down and reduce it to a small problem but the problem is with the
     declarations.py.  Some of the methods do not appear to have the
     'throws' attribute.  I get errors like this:

Traceback (most recent call last):
  File "/usr/local/bin/pyste.py", line 5, in ?
    pyste.main()
  File "/usr/local/stow/pyste/lib/python2.2/site-packages/Pyste/pyste.py", line 
367, in main
    status = Begin()
  File "/usr/local/stow/pyste/lib/python2.2/site-packages/Pyste/pyste.py", line 
213, in Begin
    return GenerateCode(parser, module, out, interfaces, multiple)
  File "/usr/local/stow/pyste/lib/python2.2/site-packages/Pyste/pyste.py", line 
334, in GenerateCode
    export.GenerateCode(codeunit, exported_names)
  File "/usr/local/stow/pyste/lib/python2.2/site-packages/Pyste/Exporter.py", li
ne 45, in GenerateCode
    self.Export(codeunit, exported_names)        
  File "/usr/local/stow/pyste/lib/python2.2/site-packages/Pyste/ClassExporter.py
", line 88, in Export
    self.InheritMethods(exported_names)
  File "/usr/local/stow/pyste/lib/python2.2/site-packages/Pyste/ClassExporter.py
", line 116, in InheritMethods
    pointers = [x.PointerDeclaration(True) for x in self.class_ if isinstance(x,
 Method)]
  File "./declarations.py", line 313, in PointerDeclaration

  File "./declarations.py", line 213, in Exceptions
AttributeError: 'Method' object has no attribute 'throws'

    I quietly fixed them (without looking for the cause) by changing
    this in declarations.py:

     212     def Exceptions(self):
     213         if self.throws is None:
     214             return ""

    to:
   
     212     def Exceptions(self):
     213         if not hasattr(self, 'throws') or self.throws is None:
     214             return ""

    It seems to work fine with this.  Sorry, I can't give you a
    specific test case.

  3. Pyste also has problems with Include and Import used together.  I
     again don't have a small test case but perhaps Nicodemus will be
     able to figure this one out.  Essentially if I add an
     Include(...) after an Import(...) nothing gets included.  However
     if I place the Include before the Import, everything seems to
     work OK.


Thanks and sorry for the lack of specific test cases.  I'm really
short on time now.

cheers,
