fc3bfad2e0 Issue #8681: Make the zlib module's error messages more informative when
the zlib itself doesn't give any detailed explanation.

3843cd8e86 Issue #8571: Fix an internal error when compressing or decompressing a
chunk larger than 1GB with the zlib module's compressor and decompressor
objects.

dd96db63f6 This reverts r63675 based on the discussion in this thread:
http://mail.python.org/pipermail/python-dev/2008-June/079988.html

Python 2.6 should stick with PyString_* in its codebase.  The PyBytes_* names
in the spirit of 3.0 are available via a #define only.  See the email thread.

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

73f57b0c05 Revert r61779 - It undid correct code and caused test_zlib to fail on all
platforms with a 64-bit long.

The Alpha/Tru64 test problem is a problem in either tarfile or test_tarfile,
not zlib.

crc32 and adler32 return 32-bit values.  by using a long thats larger than
32-bits in these functions they were prevented from wrapping around to their
signed 32-bit value that we want them to return in python 2.x.

acbd6420e3 Fix test_tarfile failures on Alpha (Tru64). The problem was caused in r61449
which made the return value signed.  On the Alpha that also lost data
since sizeof(int) != sizeof(long) and apparently adler32/crc32 return
64 bits of data.  This change keeps the signedness and continues to store the
data in a long rather than an int as was the case before r61449.

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

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.

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

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.

62b1ab1b31 Replace DL_IMPORT with PyMODINIT_FUNC and remove "/export:init..." link
command line for Windows builds.  This should allow MSVC to import and
build the Python MSVC6 project files without error.

938ace69a0 staticforward bites the dust.
The staticforward define was needed to support certain broken C
compilers (notably SCO ODT 3.0, perhaps early AIX as well) botched the
static keyword when it was used with a forward declaration of a static
initialized structure.  Standard C allows the forward declaration with
static, and we've decided to stop catering to broken C compilers.  (In
fact, we expect that the compilers are all fixed eight years later.)

I'm leaving staticforward and statichere defined in object.h as
static.  This is only for backwards compatibility with C extensions
that might still use it.

XXX I haven't updated the documentation.
