Victor Stinner 049e509a9f Issue #22207: Fix "comparison between signed and unsigned integers" warning in 
test checking for integer overflow on Py_ssize_t type: cast explicitly to
size_t.

Larry Hastings 581ee3618c Issue #20326: Argument Clinic now uses a simple, unique signature to 
annotate text signatures in docstrings, resulting in fewer false
positives.  "self" parameters are also explicitly marked, allowing
inspect.Signature() to authoritatively detect (and skip) said parameters.

Issue #20326: Argument Clinic now generates separate checksums for the
input and output sections of the block, allowing external tools to verify
that the input has not changed (and thus the output is not out-of-date).

Nadeem Vawda e6514f533e #19395: Raise exception when pickling a (BZ2|LZMA)(Compressor|Decompressor). 
The underlying C libraries provide no mechanism for serializing compressor and
decompressor objects, so actually pickling these classes is impractical.
Previously, these objects would be pickled without error, but attempting to use
a deserialized instance would segfault the interpreter.

Victor Stinner b7f1f65f1c Issue #18227: "Free" function of bz2, lzma and zlib modules has no return value (void) 2013-07-07 17:10:34 +02:00
Victor Stinner 5064a52bcb Issue #18227: Use PyMem_RawAlloc() in bz2, lzma and zlib modules 2013-07-07 16:50:27 +02:00
Nadeem Vawda a425c3d5a2 Make lzma.{encode,decode}_filter_properties private. 
These functions were originally added to support LZMA compression in the zipfile
module, and are not of interest for the majority of users.

They can be made public in 3.4 if there is user interest, but in the meanwhile,
I've opted to present a smaller, simpler API for the module's initial release.

Martin v. Löwis d1b7f3993a Silence VS 2010 warning on loss of precision (_int64 -> _int32). 
This is safe because the actual value is already range-checked.
