[3.9] bpo-41069: Make TESTFN and the CWD for tests containing non-ascii characters. (GH-21035). (GH-21156)

William Chargin eab3b3f1c6 bpo-39389: gzip: fix compression level metadata (GH-18077)
As described in RFC 1952, section 2.3.1, the XFL (eXtra FLags) byte of a
gzip member header should indicate whether the DEFLATE algorithm was
tuned for speed or compression ratio. Prior to this patch, archives
emitted by the `gzip` module always indicated maximum compression.

guoci 0e7497cb46 bpo-34898: Add mtime parameter to gzip.compress(). (GH-9704)
Without setting mtime, time.time() will be used as the timestamp which will
end up in the compressed data and each invocation of the compress() function
will vary over time.

Berker Peksag 03020cfa97 Issue #28227: gzip now supports pathlib
Patch by Ethan Furman.

Serhiy Storchaka 5f1a5187f7 Use sequence repetition instead of bytes constructor with integer argument. 2016-09-11 14:41:02 +03:00
Martin Panter e99e97762c Issue #25626: Change zlib to accept Py_ssize_t and cap to UINT_MAX
The underlying zlib library stores sizes in “unsigned int”. The corresponding
Python parameters are all sizes of buffers filled in by zlib, so it is okay
to reduce higher values to the UINT_MAX internal cap. OverflowError is still
raised for sizes that do not fit in Py_ssize_t.

Sizes are now limited to Py_ssize_t rather than unsigned long, because Python
byte strings cannot be larger than Py_ssize_t. Previously this could result
in a SystemError on 32-bit platforms.

This resolves a regression in the gzip module when reading more than UINT_MAX
or LONG_MAX bytes in one call, introduced by revision 62723172412c.

Antoine Pitrou 2dbc6e6bce Issue #23529: Limit the size of decompressed data when reading from
GzipFile, BZ2File or LZMAFile.  This defeats denial of service attacks
using compressed bombs (i.e. compressed payloads which decompress to a huge
size).

Patch by Martin Panter and Nikolaus Rath.
