* gh-107811: tarfile: treat overflow in UID/GID as failure to set it (#108369)Petr Viktorin2023-08-231-1/+2

* gh-107396: tarfiles: set self.exception before _init_read_gz() (GH-107485)balmeida-nokia2023-08-211-1/+1
| | | | | | | | | | | In the stack call of: _init_read_gz() ``` _read, tarfile.py:548 read, tarfile.py:526 _init_read_gz, tarfile.py:491 ``` a try;except exists that uses `self.exception`, so it needs to be set before calling _init_read_gz().

* bpo-26253: Add compressionlevel to tarfile stream (GH-2962)Yaron de Leeuw2022-06-251-9/+13
| | | | | | `tarfile` already accepts a compressionlevel argument for creating files. This patch adds the same for stream-based tarfile usage. The default is 9, the value that was previously hard-coded.

* bpo-45863: tarfile: don't zero out header fields unnecessarily (GH-29693)Joshua Root2022-02-091-6/+15
| | | | | | | | | | Numeric fields of type float, notably mtime, can't be represented exactly in the ustar header, so the pax header is used. But it is helpful to set them to the nearest int (i.e. second rather than nanosecond precision mtimes) in the ustar header as well, for the benefit of unarchivers that don't understand the pax header. Add test for tarfile.TarInfo.create_pax_header to confirm correct behaviour.

| | | | | | | * during tarfile parsing, a zlib error indicates invalid data * tarfile.open now raises a descriptive exception from the zlib error * this makes it clear to the user that they may be trying to open a corrupted tar file

* bpo-39717: [tarfile] update nested exception raising (GH-23739)Ethan Furman2020-12-121-32/+33
| | | | - `from None` if the new exception uses, or doesn't need, the previous one - `from e` if the previous exception is still relevant

* bpo-41316: Make tarfile follow specs for FNAME (GH-21511)Artem Bulgakov2020-09-071-0/+2
| | | | | | | | | | tarfile writes full path to FNAME field of GZIP format instead of just basename if user specified absolute path. Some archive viewers may process file incorrectly. Also it creates security issue because anyone can know structure of directories on system and know username or other personal information. RFC1952 says about FNAME: This is the original name of the file being compressed, with any directory components removed. So tarfile must remove directory names from FNAME and write only basename of file. Automerge-Triggered-By: @jaraco
* bpo-39017: Avoid infinite loop in the tarfile module (GH-21454)Rishi2020-07-151-0/+2
| | | | | Avoid infinite loop when reading specially crafted TAR files using the tarfile module (CVE-2019-20907).
* bpo-18819: tarfile: only set device fields for device files (GH-18080)William Chargin2020-02-121-2/+10
| | | | | | The GNU docs describe the `devmajor` and `devminor` fields of the tar header struct only in the context of character and block special files, suggesting that in other cases they are not populated. Typical utilities behave accordingly; this patch teaches `tarfile` to do the same.
* bpo-39430: Fix race condition in lazy imports in tarfile. (GH-18161)Serhiy Storchaka2020-01-241-10/+8
| | | Use `from ... import ...` to ensure module is fully loaded before accessing its attributes.
* bpo-29435: Allow is_tarfile to take a filelike obj (GH-18090)William Woodruff2020-01-231-1/+6
| | | `is_tarfile()` now supports `name` being a file or file-like object.
* Add missing docstrings for TarInfo objects (#12555)Raymond Hettinger2019-03-271-7/+46

* bpo-34043: Optimize tarfile uncompress performance (GH-8089)INADA Naoki2018-07-061-18/+12
| | | | | | | | | | | tarfile._Stream has two buffer for compressed and uncompressed data. Those buffers are not aligned so unnecessary bytes slicing happens for every reading chunks. This commit bypass compressed buffering. In this benchmark [1], user time become 250ms from 300ms. [1]: https://bugs.python.org/msg320763
* bpo-34010: Fix tarfile read performance regression (GH-8020)hajoscher2018-07-041-9/+11
| | | | During buffered read, use a list followed by join instead of extending a bytes object. This is how it was done before but changed in commit b506dc32c1a.

| | | | | | tarfile and zipfile now sort directory listing to generate tar and zip archives in a more reproducible way. See also https://reproducible-builds.org/docs/stable-inputs/ on that topic.
