rezip 0.5.0

Repack ZIP archives

Repack ZIP archives with the possibility to update metadata, e.g., Unix access right bits. Rezip can be used to fix Windows generated ZIP archives (e.g., Python wheel packages) so that the archives members have suitable access rights for usage on Linux.

Using rezip

Usage:

rezip [--inplace]
      [--glob|-g]
      [--normalize-access-rights] [--date-time DATETIME]
      [--output|-o OUTPUT]
      INPUT [INPUT]...

--inplace

Repack in place. This is done by writing to a temporary file and then replace the original input file with the temporary output file. On Posix systems an atomic move is used for the replacement of the original input file by the temporary output file.

More than one INPUT file can be specified if --inplace is used.

Note: The --inplace option is mutual exclusive with the --output option.

--glob | -g

Treat the input file names as shell glob patterns.

--normalize-access-rights

Normalize the Unix access right bits. Access rights of regular non-executable files are modified to 0o644. Access rights of executable files are modified to be 0o755. Rezip considers files that already have any executable bit set and files that are identified as ELF programs or ELF dynamic libraries as executable.

Identification as an ELF file is done by looking if the file starts with the ELF magic bytes b"\x7fELF" and then reading the e_type field of the ELF header. As this is in the end only a heuristic, wrong executable-identifcations may happen.

--date-time DATETIME

Set the date time of all files in the ZIP archive to DATETIME. The date time DATETIME must be a Unix timestamp or a date time in ISO format that is understood by datetime.datetime.fromisoformat.

INPUT

The ZIP archive to read

More than one INPUT file can be specified if --inplace is used. Otherwise, only one INPUT file is allowed.

--output | -o

The ZIP archive to create and write to.

Note: The --output option is mutual exclusive with the --inplace option.

Changelog history

v0.5.0 (2019-05-26)

• Set zipfile.ZipInfo.create_system (PKZIP 4.4.2 version made by) to 3 (Unix) when modifying zipfile.ZipInfo.external_attr to set Unix permissions. Unix permissions stored in zipfile.ZipInfo.external_attr are not correctly restored by zipfile or Info-ZIP if zipfile.ZipInfo.create_system is 0 (FAT).

v0.4.1 (2019-05-21)

• Updated README.

v0.4.0 (2019-05-21)

• New --glob (or -g) option to treat input file names as shell glob patterns.

• Allow multiple input files when using --inplace.

• New --output (or -o) option to specify the output file.
