Nick Coghlan 3814a911aa Fix for bug 1705170 - contextmanager swallowing StopIteration (2.5 backport candidate) 2007-11-02 10:09:12 +00:00
Nick Coghlan afd5e63e24 Finish bringing SVN into line with latest version of PEP 343 by getting rid of all remaining references to context objects that I could find. Without a __context__() method context objects no longer exist. Also get test_with working again, and adopt a suggestion from Neal for decimal.Context.get_manager() 2006-05-03 13:02:47 +00:00
Guido van Rossum da5b701aee Get rid of __context__, per the latest changes to PEP 343 and python-dev
discussion.
There are two places of documentation that still mention __context__:
Doc/lib/libstdtypes.tex -- I wasn't quite sure how to rewrite that without
spending a whole lot of time thinking about it; and whatsnew, which Andrew
usually likes to change himself.

Tim Peters d845e53b5b Rev 45706 renamed stuff in contextlib.py, but didn't rename
uses of it in test_with.py.  As a result, test_with has been skipped
(due to failing imports) on all buildbot boxes since.  Alas, that's
not a test failure -- you have to pay attention to the

    1 skip unexpected on PLATFORM:
        test_with

kinds of output at the ends of test runs to notice that this got
broken.

It's likely that more renaming in test_with.py would be desirable.

Phillip J. Eby 9444bd51c4 Fix SF#1462485: StopIteration raised in body of 'with' statement suppressed 2006-04-03 20:05:05 +00:00
Guido van Rossum f669436189 Um, I thought I'd already checked this in.
Anyway, this is the changes to the with-statement
so that __exit__ must return a true value in order
for a pending exception to be ignored.
The PEP (343) is already updated.
2006-03-10 02:28:35 +00:00
Guido van Rossum 1a5e21e033 Updates to the with-statement:
- New semantics for __exit__() -- it must re-raise the exception
  if type is not None; the with-statement itself doesn't do this.
  (See the updated PEP for motivation.)

- Added context managers to:
  - file
  - thread.LockType
  - threading.{Lock,RLock,Condition,Semaphore,BoundedSemaphore}
  - decimal.Context

- Added contextlib.py, which defines @contextmanager, nested(), closing().

- Unit tests all around; bot no docs yet.

Guido van Rossum c2e20744b2 PEP 343 -- the with-statement.
This was started by Mike Bland and completed by Guido
(with help from Neal).

This still needs a __future__ statement added;
Thomas is working on Michael's patch for that aspect.

There's a small amount of code cleanup and refactoring
in ast.c, compile.c and ceval.c (I fixed the lltrace
behavior when EXT_POP is used -- however I had to make
lltrace a static global).
