Gregory P. Smith 79e42a0e08 Fix zlib crash from zlib.decompressobj().flush(val) when val was not positive.
It tried to allocate negative or zero memory.  That fails.

Gregory P. Smith 88440960f9 A stab in the dark attempt to fix the alpha/tru64 buildbot problem and add more
test coverage of valid inputs to zlib.crc32.

Gregory P. Smith c856fa811d Add a test to make sure zlib.crc32 and binascii.crc32 return the same thing.
Fix a buglet in binascii.crc32, the second optional argument could previously
have a signedness mismatch with the C variable its going into.

Gregory P. Smith f48f9d38c0 Force zlib.crc32 and zlib.adler32 to return a signed integer on all platforms
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

Neal Norwitz 6e73aaab47 Patch #1503046, Conditional compilation of zlib.(de)compressobj.copy
copy is only in newer versions of zlib.  This should allow zlibmodule
to work with older versions like the Tru64 buildbot.

Georg Brandl 8d3342b489 Patch #1435422: zlib's compress and decompress objects now have a
copy() method.

Andrew M. Kuchling 3b585b30c0 [Bug #1083110] calling .flush() on decompress objects causes a segfault due to an uninitialized pointer: fixes the problem and adds a test case 2004-12-28 20:10:48 +00:00
Neil Schemenauer 6412b121f6 Remove a number of tests that differ only in input data size. It seems
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.

Raymond Hettinger 6d362b25c5 SF bug #785222: zlib monotonic test
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.

Walter Dörwald 21d3a32b99 Combine the functionality of test_support.run_unittest()
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.

Guido van Rossum 7d9ea5013f - Thanks to Scott David Daniels, a subtle bug in how the zlib
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.

Guido van Rossum a6fa0e6f2e Portable way of producing unsigned 32-bit hex output to print the
CRCs.
2002-08-12 15:26:05 +00:00
Barry Warsaw 04f357cffe Get rid of relative imports in all unittests. Now anything that
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. :)

Jeremy Hylton 511e2cacc4 [ #403753 ] zlib decompress; uncontrollable memory usage
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.

Andrew M. Kuchling fcfc8d5c0e Patch #441091 from Finn Bock: the more advanced flush options are not
available in java, so only use the advanced flush options if they
  are defined in the zlib module.

Andrew M. Kuchling dca7e00fd5 Added simple test for the flush() method of compression objects, trying the
different flush values Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FULL_FLUSH.

Guido van Rossum 446898ff4a Use hex() when outputting the various checksums so the test output is the
same on 32 and 64 bit machines.
