[issue8601] bz2.BZ2File should support "with" protocol per PEP 343

[Matt Wartell]

New submission from Matt Wartell :

As the bz2.BZ2File object claims to be a file-like object it should conform to 
PEP 343 "The 'with' statement" by implementation of the __enter__ and __exit__ 
methods.


boring, substantiating detail follows:

[issue8602] documentation of bz2 module mildly erroneous

[Matt Wartell]

New submission from Matt Wartell :

This is related to http://bugs.python.org/issue8601 "bz2.BZ2File should support 
"with" protocol per PEP 343"

The documentation at http://docs.python.org/library/bz2.html states:

   "This module provides a comprehensive interface for the bz2 compression 
library. It implements a complete file interface,..." 

although bz2.BZ2File does not support the __enter__ and __exit__ methods so 
arguably doesn't implement the "complete file interface". If issue8601 is 
declined then the documentation should probably note this exception.

Sorry for the dup, and thanks for the patch. 

My patch for Module/bz2module.c was almost done - I learned a lot in the 
process, but foremost to check better for dups, first ;)

[issue8602] documentation of bz2 module mildly erroneous

[Matt Wartell]

Matt Wartell  added the comment:

Per request, I have attached a context diff for both bz2.txt and 3.0.txt 
suitable for http://docs.python.org/library/bz2.html and 
http://docs.python.org/release/3.0.1/whatsnew/3.0.html respectively. 

The modification in bz2.txt may border on redundant and overly verbose and 
should be reviewed for style consistency.

I have sanity-checked the modified files with sphinx-build html which generates 
clean, consistent markup.
