* Make weak references subclassable:Fred Drake2004-07-021-22/+3
| | | | | | | | | | | | | | | | | | | | | | - weakref.ref and weakref.ReferenceType will become aliases for each other - weakref.ref will be a modern, new-style class with proper __new__ and __init__ methods - weakref.WeakValueDictionary will have a lighter memory footprint, using a new weakref.ref subclass to associate the key with the value, allowing us to have only a single object of overhead for each dictionary entry (currently, there are 3 objects of overhead per entry: a weakref to the value, a weakref to the dictionary, and a function object used as a weakref callback; the weakref to the dictionary could be avoided without this change) - a new macro, PyWeakref_CheckRefExact(), will be added - PyWeakref_CheckRef() will check for subclasses of weakref.ref This closes SF patch #983019.
* Adds support for DB.pget and DBCursor.pget methods.Gregory P. Smith2004-06-281-3/+198

* SF patch / bug #967763Gregory P. Smith2004-06-271-43/+76
| | | | | | | | | | | | Fix memory leaks revealed by valgrind and ensuing code inspection. In the existing test suite valgrind revealed two memory leaks (DB_get and DBC_set_range). Code inspection revealed that there were many other potential similar leaks (many on odd code error paths such as passing something other than a DBTxn object for a txn= parameter or in the face of an out of memory error). The most common case that would cause a leak was when using recno or queue format databases with integer keys, sometimes only with an exception exit.

* SF patch 876130: add C API to datetime module, from Anthony Tuininga.Tim Peters2004-06-201-0/+30
| | | | | | The LaTeX is untested (well, so is the new API, for that matter). Note that I also changed NULL to get spelled consistently in concrete.tex. If that was a wrong thing to do, Fred should yell at me.

* Bug 975996: Add _PyTime_DoubleToTimet to C APITim Peters2004-06-202-12/+20
| | | | | | | | | | | New include file timefuncs.h exports private API function _PyTime_DoubleToTimet() from timemodule.c. timemodule should export some other functions too (look for painful bits in datetimemodule.c). Added insane-argument checking to datetime's assorted fromtimestamp() and utcfromtimestamp() methods. Added insane-argument tests of these to test_datetime, and insane-argument tests for ctime(), localtime() and gmtime() to test_time.
* Raise ValueError when value being stored in a time_t variable will result inBrett Cannon2004-06-191-5/+40
| | | | | | | | | | | more than a second of precision. Primarily affects ctime, localtime, and gmtime. Closes bug #919012 thanks to Tim Peters' code. Tim suggests that the new funciton being introduced, _PyTime_DoubletoTimet(), should be added to the internal C API and then used in datetime where appropriate. Not being done now for lack of time.

* SF patch #969180, hotshot incorrectly computes elapsed time by JasonNeal Norwitz2004-06-131-5/+7
| | | | | | | | | | | | | | | | | Beardsley. If the seconds are different, we still need to calculate the differences between milliseconds. Also, on a Gentoo Linux (2.6.5) dual Athlon MP box with glibc 2.3, time can go backwards. This probably happens when the process switches the CPU it's running on. Time can also go backwards when running NTP. If we detect a negative time delta (ie, time went backwards), return a delta of 0. This prevents an illegal array access elsewhere. I think it's safest to *not* update prev_timeofday in this case, so we return without updating. Backport candidate.

* Ensure path is initialized to prevent freeing random memoryNeal Norwitz2004-06-091-4/+2

* Valgrind was reporting an uninitialized read for bad input.Neal Norwitz2004-06-061-1/+2
| | | | | | | | | This fixes the problem and the test passes. I'm not sure the test is really correct though. It seems like it would be better to raise an exception. I think that wasn't done for backwards compatability. Bugfix candidate.

* SF patch #872326: Generator expression implementationRaymond Hettinger2004-05-191-6/+115
| | | | | | | | | | | | | | (Code contributed by Jiwon Seo.) The documentation portion of the patch is being re-worked and will be checked-in soon. Likewise, PEP 289 will be updated to reflect Guido's rationale for the design decisions on binding behavior (as described in in his patch comments and in discussions on python-dev). The test file, test_genexps.py, is written in doctest format and is meant to exercise all aspects of the the patch. Further additions are welcome from everyone. Please stress test this new feature as much as possible before the alpha release.
