| | | | | | | | | | decompressobj().flush(). Additionally, fix a bug where a MemoryError in allocating a bytes object could leave the decompressor object in an invalid state (with its unconsumed_tail member being NULL). Patch by Serhiy Storchaka.

| | | | | chunk larger than 1GB with the zlib module's compressor and decompressor objects.
* Issue #8193: Fix test_zlib failure with zlib 1.2.4.Antoine Pitrou2010-04-061-1/+1

* convert usage of fail* to assert*Benjamin Peterson2009-06-301-6/+6
|
* Change more tests to use import_module for the modules thatR. David Murray2009-03-301-1/+2
| | | | | should cause tests to be skipped. Also rename import_function to the more descriptive get_attribute and add a docstring.
* Fix zlib crash from zlib.decompressobj().flush(val) when val was not positive.Gregory P. Smith2008-04-091-0/+5
| | | | It tried to allocate negative or zero memory. That fails.

| | | | test coverage of valid inputs to zlib.crc32.
* Add a test to make sure zlib.crc32 and binascii.crc32 return the same thing.Gregory P. Smith2008-03-181-0/+6
| | | | | Fix a buglet in binascii.crc32, the second optional argument could previously have a signedness mismatch with the C variable its going into.
* Force zlib.crc32 and zlib.adler32 to return a signed integer on all platformsGregory P. Smith2008-03-171-0/+9
| | | | | | | | | regardless of the native sizeof(long) used in the integer object. This somewhat odd behavior of returning a signed is maintained in 2.x for compatibility reasons of always returning an integer rather than a long object. Fixes Issue1202 for Python 2.6

* Patch #1503046, Conditional compilation of zlib.(de)compressobj.copyNeal Norwitz2006-06-121-57/+59
| | | | | copy is only in newer versions of zlib. This should allow zlibmodule to work with older versions like the Tru64 buildbot.

* Remove a number of tests that differ only in input data size. It seemsNeil Schemenauer2004-06-051-161/+59
| | | | | | no bug motivated their inclusion and the chance of them triggering a problem seems unlikely. Refactor to reduce code duplication. Rename 'hamlet_scene' to 'HAMLET_SCENE'. Test is much faster now. Closes #960995.
* Remove lots of magic constants.Neil Schemenauer2004-06-051-23/+38

* SF bug #785222: zlib monotonic testRaymond Hettinger2003-08-311-11/+0
| | | | | | 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.
* Combine the functionality of test_support.run_unittest()Walter Dörwald2003-05-011-12/+12
| | | | | | | | | | and test_support.run_classtests() into run_unittest() and use it wherever possible. Also don't use "from test.test_support import ...", but "from test import test_support" in a few spots. From SF patch #662807.

| | | | | | | | extension implemented flush() was fixed. Scott also rewrite the zlib test suite using the unittest module. (SF bug #640230 and patch #678531.) Backport candidate I think.

* Get rid of relative imports in all unittests. Now anything thatBarry Warsaw2002-07-231-1/+1
| | | | | | | | | | | imports e.g. test_support must do so using an absolute package name such as "import test.test_support" or "from test import test_support". This also updates the README in Lib/test, and gets rid of the duplicate data dirctory in Lib/test/data (replaced by Lib/email/test/data). Now Tim and Jack can have at it. :)
* Fix SF #544995 (zlib crash on second flush call)Jeremy Hylton2002-04-191-0/+6
| | | | | | Bug fix by mhammond. Bug fix candidate for 2.2, not present in 2.1.

* [ #403753 ] zlib decompress; uncontrollable memory usageJeremy Hylton2001-10-161-0/+30
| | | | | | | | | | | | | Mostly by Toby Dickenson and Titus Brown. Add an optional argument to a decompression object's decompress() method. The argument specifies the maximum length of the return value. If the uncompressed data exceeds this length, the excess data is stored as the unconsumed_tail attribute. (Not to be confused with unused_data, which is a separate issue.) Difference from SF patch: Default value for unconsumed_tail is "" rather than None. It's simpler if the attribute is always a string.
* Patch #441091 from Finn Bock: the more advanced flush options are notAndrew M. Kuchling2001-08-101-15/+20
| | | | | available in java, so only use the advanced flush options if they are defined in the zlib module.
