* bpo-45475: Revert `__iter__` optimization for GzipFile, BZ2File, and ↵Inada Naoki2021-10-191-4/+0
| | | | | LZMAFile. (GH-29016) This reverts commit d2a8e69c2c605fbaa3656a5f99aa8d295f74c80e.
* bpo-44439: BZ2File.write() / LZMAFile.write() handle buffer protocol ↵Ma Lin2021-06-221-4/+12
| | | | | | | correctly (GH-26764) No longer use len() to get the length of the input data. For some buffer protocol objects, the length obtained by using len() is wrong.
* bpo-43787: Add __iter__ to GzipFile, BZ2File, and LZMAFile (GH-25353)Inada Naoki2021-04-131-0/+4

* bpo-43785: Improve BZ2File performance by removing RLock (GH-25299)Inada Naoki2021-04-121-59/+44
| | | | | | Remove `RLock` from `BZ2File`. It makes `BZ2File` to thread unsafe, but gzip and lzma don't use it too. Co-authored-by: Gregory P. Smith <greg@krypto.org>
* bpo-43510: Implement PEP 597 opt-in EncodingWarning. (GH-19481)Inada Naoki2021-03-291-0/+1
| | | | | | | | | | | See [PEP 597](https://www.python.org/dev/peps/pep-0597/). * Add `-X warn_default_encoding` and `PYTHONWARNDEFAULTENCODING`. * Add EncodingWarning * Add io.text_encoding() * open(), TextIOWrapper() emits EncodingWarning when encoding is omitted and warn_default_encoding is enabled. * _pyio.TextIOWrapper() uses UTF-8 as fallback default encoding used when failed to import locale module. (used during building Python) * bz2, configparser, gzip, lzma, pathlib, tempfile modules use io.text_encoding(). * What's new entry
* bpo-40443: Remove unused imports in the stdlib (GH-19803)Victor Stinner2020-04-301-1/+0

* bpo-39357: Update bz2 docstring: remove buffering (GH-18036)Victor Stinner2020-01-171-2/+0
| | | Thanks Karthikeyan Singaravelan for the report ;-)
* bpo-39357: Remove buffering parameter of bz2.BZ2File (GH-18028)Victor Stinner2020-01-161-9/+1
| | | | | | | Remove the buffering parameter of bz2.BZ2File. Since Python 3.0, it was ignored and using it was emitting a DeprecationWarning. Pass an open file object to control how the file is opened. The compresslevel parameter becomes keyword-only.
* bpo-35128: Fix spacing issues in warning.warn() messages. (GH-10268)Pablo Aguiar2018-11-011-1/+1

* bpo-33487: improve BZ2File Deprecation and documentation. (GH-6785)Matthias Bussonnier2018-09-111-5/+9
| | | | Emit warning when None passed explicitly, list Python version since deprecation in warning message and docs.
* bpo-31370: Remove support for threads-less builds (#3385)Antoine Pitrou2017-09-071-5/+1
| | | | | | * Remove Setup.config * Always define WITH_THREAD for compatibility.

* Issue #23529: Limit the size of decompressed data when reading fromAntoine Pitrou2015-04-101-199/+38
| | | | | | | | 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.
