* tee object is no longer subclassable
* independent iterators renamed to "itertools.tee_iterator"
* fixed doc string typo and added entry in the module doc string
* Fixed typo in docstring for 'failUnlessAlmostEqual()'
* Removed unnecessary use of 'float()' for time values.
* Removed apparently unnecessary import of unittest. At some point in
the distant past I believe it was necessary otherwise the 'TestCase'
that a module saw was not the same as the 'TestCase' seen within
'unittest', and the user's TestCase subclasses were not recognised as
subclasses of the TestCase seen within unittest. Seems not to be
necessary now.
charmaptranslate_makespace() allocated more memory than required for the
next replacement but didn't remember that fact, so memory size was growing
exponentially every time a replacement string is longer that one character.
This fixes SF bug #828737.
It works like the pure python verion except:
* it stops storing data after of the iterators gets deallocated
* the data queue is implemented with two stacks instead of one dictionary.
of the dispatcher object break. e.g. if you close() the object, it
tries to remove itself from the default map, not from the map the
dispatcher was created with.
The patch, from Stephane Ninin, records the map as an attribute of
the dispatcher instance.
2.3 bugfix candidate.
The patch was tweaked slightly. It's get a different mechanism for
generating the cnonce which uses /dev/urandom when possible to
generate less-easily-guessed random input.
Also rearrange the imports so that they are alphabetical and
duplicates are eliminated.
Add a few XXX comments about things left undone and things that could
be improved.
key provides C support for the decorate-sort-undecorate pattern.
reverse provide a stable sort of the list with the comparisions reversed.
* Amended the docs to guarantee sort stability.
* Added C coded getrandbits(k) method that runs in linear time.
* Call the new method from randrange() for ranges >= 2**53.
* Adds a warning for generators not defining getrandbits() whenever they
have a call to randrange() with too large of a population.
is None, the next row read is used as the fieldnames. In the common case,
this means the programmer doesn't need to know the fieldnames ahead of time.
The first row of the file will be used. In the uncommon case, this means
the programmer can set the reader's fieldnames attribute to None at any time
and have the next row read as the next set of fieldnames, so a csv file can
contain several "sections", each with different fieldnames.
db that is opened. DB_THREAD and DB_INIT_LOCK allow for multithreaded
access. DB_PRIVATE prevents the DBEnv from using the filesystem
(making it only usable by this process; and in this implementation
using one DBEnv per bsddb database)
why in a new comment. My home Win98SE box is one of the "real systems"
alluded to (my system "default sound" appears to have vanished sometime
in the last month, that's certainly not a Python bug, and the MS
PlaySound docs are correct in their explanation of what happens then).
Bugfix candidate. If someone can still sneak it into 2.3.1, that would
be good.
method (PyUnit issue 563882, thanks to Alexandre Fayolle)
- Ignore non-callable attributes of classes when searching for test
method names (PyUnit issue 769338, thanks to Seth Falcon)
- New assertTrue and assertFalse aliases for comfort of JUnit users
- Automatically discover 'runTest()' test methods (PyUnit issue 469444,
thanks to Roeland Rengelink)
- Dropped Python 1.5.2 compatibility, merged appropriate shortcuts from
Python CVS; should work with Python >= 2.1.
- Removed all references to string module by using string methods instead
features in BerkeleyDB not exposed. notably: the DB_MPOOLFILE interface
has not yet been wrapped in an object.
Adds support for building and installing bsddb3 in python2.3 that has
an older version of this module installed as bsddb without conflicts.
The pybsddb.sf.net build/packaged version of the module uses a
dynamicly loadable module called _pybsddb rather than _bsddb.
test_bad_address(): Recover from that VeriSign thought it would boost
its corporate coffers to start resolving http://www.sadflkjsasadf.com/.
Bugfix candidate -- although the bug is more VeriSign's than Python's!
Add support for the iterator and mapping protocols.
For Py2.3, this was done for shelve, dumbdbm and other mapping objects, but
not for bsddb and dbhash which were inadvertently missed.
1. Remove "idle" script, it lives in Tools/scripts/ now.
2. Remove shebang from idle.py, should be called explicitly.
3. Remove obsolete test code from rpc.py; needs unit test.
file_truncate(): C doesn't define what fflush(fp) does if fp is open
for update, and the preceding I/O operation on fp was input. On Windows,
fflush() actually changes the current file position then. Because
Windows doesn't support ftruncate() directly, this not only caused
Python's file.truncate() to change the file position (contra our docs),
it also caused the file not to change size.
Repaired by getting the initial file position at the start, restoring
it at the end, and tossing all the complicated micro-efficiency checks
trying to avoid "provably unnecessary" seeks. file.truncate() can't
be a frequent operation, and seeking to the current file position has
got to be cheap anyway.
Bugfix candidate.
random.sample() uses one of two algorithms depending on the ratio of the
sample size to the population size. One of the algorithms accepted any
iterable population argument so long as it defined __len__(). The other
had a stronger requirement that the population argument be indexable.
While it met the documentation specifications which insisted that the
population argument be a sequence, it made random.sample() less usable
with sets. So, the second algorithm was modified to coerce non-indexable
iterables and dictionaries into a tuple before proceeding.
quotes. Fixes SF bug #794466, with the essential patch provided by
Stuart D. Gathman. Specifically,
_parseparam(), _get_params_preserve(): Use the parsing function that
takes quotes into account, as given (essentially) in the bug report's
test program.
Backport candidate.
For smaller datasets, it is not always true the increasing the compression
level always results in better compression. Removed the test which made
this invalid assumption.

* Convert three test modules to unittest format.
* Expanded coverage in test_structseq.py.
* Raymond added a new test in test_sets.py
When the indents were set to longer than the width and long word breaking
was enabled, an infinite loop would result because the inner loop did not
assure that at least one character was stripped off on every pass.
platforms (e.g., Cygwin) that are "particular" about open files, this will
cause other regression tests that use the same temp file to fail:
$ ./python.exe -E -tt Lib/test/regrtest.py -l
test_largefile test_mmap test_mutants
test_largefile
test test_largefile failed -- got -1794967295L, but expected 2500000001L
test_mmap
test test_mmap crashed -- exceptions.IOError: [Errno 13] Permission denied: '@test'
test_mutants
test test_mutants crashed -- exceptions.IOError: [Errno 13] Permission denied: '@test'
This patch solves the problem by adding missing "try/finally" blocks. Note
that the "large" size of this patch is due to many white space changes --
otherwise, the patch is small.
I tested this patch under Red Hat Linux 8.0 too.
test_rfc2231_no_language_or_charset_in_boundary(),
test_rfc2231_no_language_or_charset_in_charset(): New tests for proper
decoding of some RFC 2231 headers.
Backport candidate (as was the Utils.py 1.25 change) to both Python
2.3.1 and 2.2.4 -- will do momentarily.
can be None, and what to do in that situation.
get_filename(), get_boundary(), get_content_charset(): Make sure these
handle RFC 2231 headers without a CHARSET field.
Backport candidate (as was the Utils.py 1.25 change) to both Python
2.3.1 and 2.2.4 -- will do momentarily.
* Relaxed the argument restrictions for non-operator methods. They now
allow any iterable instead of requiring a set. This makes the module
a little easier to use and paves the way for an efficient C
implementation which can take better advantage of iterable arguments
while screening out immutables.
* Deprecated Set.update() because it now duplicates Set.union_update()
* Adapted the tests and docs to include the above changes.
* Added more test coverage including testing identities and checking
to make sure non-restartable generators work as arguments.
Will backport to Py2.3.1 so that the interface remains consistent
across versions. The deprecation of update() will be changed to
a FutureWarning.
[ 784825 ] fix obscure crash in descriptor handling
Should be applied to release23-maint and in all likelyhood
release22-maint, too.
Certainly doesn't apply to release21-maint.
The default seed is time.time().
Multiplied by 256 before truncating so that fractional seconds are used.
This way, two successive calls to random.seed() are much more likely
to produce different sequences.
