of tuple) that provides incremental decoders and encoders (a way to use
stateful codecs without the stream API). Functions
codecs.getincrementaldecoder() and codecs.getincrementalencoder() have
been added.
Since it's never intended that this script be run by
regrtest.py, it shouldn't have been named with a "test_"
prefix to begin with. A consequence is that we shouldn't
see useless:
test_hashlib_speed skipped -- not a unit test (stand alone benchmark)
lines in regrtest output anymore.
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.
an error code, this let `self` leak. This is a disaster
on Windows, since `self` already points to a newly-opened
file object, and it was impossible for Python code to
close the thing since the only reference to it was in a
blob of leaked C memory.
test_hotshot test_bad_sys_path(): This new test provoked
the C bug above. This test passed, but left an open
"@test" file behind, which caused a massive cascade of
bogus test failures in later, unrelated tests on Windows.
Changed the test code to remove the @test file it leaves
behind, which relies on the change above to close that
file first.
The failure definitely seems timing related. This change *seems* to work.
Since the failure isn't doesn't occur consistently, it's hard to tell.
Running these tests on Solaris in this order:
test_urllibnet test_operator test_cgi \
test_isinstance test_future test_ast test_logging
generally caused a failure (about 50% of the time) before the sleep.
I couldn't provoke the failure with the sleep.
This should really be cleaned up by using threading.Events or something
so it is not timing dependent and doesn't hang forever on failure.
test_codecmaps_tw test_importhooks test_socket_ssl
I don't completely understand the cause, but there's a lot of import magic
going on and this is the smallest change which fixes the problem.
want to wait forever if we don't receive the last message. But we also
don't want the test to fail if we shutdown too quickly. I can't reliably
reproduce this failure, so I'm kinda guessing this is the problem.
We'll see if this band-aid helps.
The culprit was an expression-less yield -- the first apparently in
the standard library. I added a unit test for this.
Also removed the hack to force compilation of test_with.py.
added message attribute compared to the previous version of Exception. It is
also a new-style class, making all exceptions now new-style. KeyboardInterrupt
and SystemExit inherit from BaseException directly. String exceptions now
raise DeprecationWarning.
Applies patch 1104669, and closes bugs 1012952 and 518846.
- 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.
