* [3.13] gh-126565: Skip `zipfile.Path.exists` check in write mode (GH-126576) ↵Miss Islington (bot)2024-11-101-1/+1
| | | | | | | | | | | | | | | | | | (#126642) gh-126565: Skip `zipfile.Path.exists` check in write mode (GH-126576) When `zipfile.Path.open` is called, the implementation will check whether the path already exists in the ZIP file. However, this check is only required when the ZIP file is in read mode. By swapping arguments of the `and` operator, the short-circuiting will prevent the check from being run in write mode. This change will improve the performance of `open()`, because checking whether a file exists is slow in write mode, especially when the archive has many members.

* gh-113971: Make `zipfile.ZipInfo._compresslevel` public as `.compress_level` ↵Gregory P. Smith2024-01-121-9/+18
| | | | | | | | | | | (#113969) Make zipfile.ZipInfo.compress_level public. A property is used to retain the behavior of the ._compresslevel. People constructing zipfile.ZipInfo instances to pass into existing APIs to control per-file compression levels already treat this as public, there was never a reason for it not to be. I used the more modern name compress_level instead of compresslevel as the keyword argument on other ZipFile APIs is called to be consistent with compress_type and a general long term preference of not runningwordstogether without a separator in names.

* gh-103861: Fix Zip64 extensions not being properly applied in some cases ↵Carey Metcalfe2023-05-161-15/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (#103863) Fix Zip64 extensions not being properly applied in some cases: Fixes an issue where adding a small file to a `ZipFile` object while forcing zip64 extensions causes an extra Zip64 record to be added to the zip, but doesn't update the `min_version` or file sizes in the primary central directory header. Also fixed an edge case in checking if zip64 extensions are required: This fixes an issue where if data requiring zip64 extensions was added to an unseekable stream without specifying `force_zip64=True`, zip64 extensions would not be used and a RuntimeError would not be raised when closing the file (even though the size would be known at that point). This would result in successfully writing corrupt zip files. Deciding if zip64 extensions are required outside of the `FileHeader` function means that both `FileHeader` and `_ZipWriteFile` will always be in sync. Previously, the `FileHeader` function could enable zip64 extensions without propagating that decision to the `_ZipWriteFile` class, which would then not correctly write the data descriptor record or check for errors on close. If anyone is actually using `ZipInfo.FileHeader` as a public API without explicitly passing True or False in for zip64, their own code may still be susceptible to that kind of bug unless they make a similar change to where the zip64 decision happens.

* GH-92184: Convert os.altsep to '/' in filenames when creating ZipInfo ↵Carey Metcalfe2023-05-111-0/+2
| | | | | | | | | objects (#92185) This causes the zipfile module to also consider the character defined by `os.altsep` (if there is one) to be a path separator and convert it to a forward slash, as defined by the zip specification. A logical no-op on all known platforms today as os.altsep is currently only set to a meaningful value on Windows (where it is "/").
