RPM-PAYLOADFLAGS(7) Miscellaneous Information Manual RPM-PAYLOADFLAGS(7)
rpm-payloadflags - RPM payload flags
w[FLAGS].TYPE
The payload flags determine how the payload of an RPM package is
compressed when the package is built. The flags are stored in the
Payloadcompressor and Payloadflags tags of the package header,
which are used to determine how to uncompress the payload contents
during installation.
The peculiar syntax is directly inherited from librpm's Fopen() IO
API, where w means opening a file for writing.
The following compression types are supported, but availability
may vary depending on how RPM was compiled.
┌────────┬───────────────────────────────────────────────────────┐
│ TYPE │ Description │
├────────┼───────────────────────────────────────────────────────┤
│ ufdio │ uncompressed │
├────────┼───────────────────────────────────────────────────────┤
│ gzdio │ gzip (aka zlib) │
├────────┼───────────────────────────────────────────────────────┤
│ bzdio │ bzip2 │
├────────┼───────────────────────────────────────────────────────┤
│ xzdio │ xz │
├────────┼───────────────────────────────────────────────────────┤
│ lzdio │ legacy lzma │
├────────┼───────────────────────────────────────────────────────┤
│ zstdio │ zstd │
└────────┴───────────────────────────────────────────────────────┘
The compression FLAGS must be listed in the following order and
can be any of:
┌────────┬───────────────────────────────────────┬───────────────┐
│ FLAGS │ Description │ Types │
├────────┼───────────────────────────────────────┼───────────────┤
│ <0-9> │ compression level │ all (ufdio │
│ │ │ ignores) │
├────────┼───────────────────────────────────────┼───────────────┤
│ T[0-N] │ number of threads (no number or 0 = │ xzdio, zstdio │
│ │ autodetect) │ │
├────────┼───────────────────────────────────────┼───────────────┤
│ L<0-9> │ window size(see --long in zstd(1)) │ zstdio │
└────────┴───────────────────────────────────────┴───────────────┘
If a flag is omitted, the compressor's default value will be used.
A higher compression level generally means better compression
ratio at the cost of increased resource use and compression times.
T is equivalent to T0 and causes the number of threads to be
automatically detected. Note that while using threads can speed up
compression considerably, it typically causes the compression
ratio to go down, and make the output less predictable.
┌──────────────┬─────────────────────────────────────────────────┐
│ Mode │ Description │
├──────────────┼─────────────────────────────────────────────────┤
│ w9.gzdio │ gzip level 9, default for package payload │
├──────────────┼─────────────────────────────────────────────────┤
│ w9.bzdio │ bzip2 level 9, bzip2's default │
├──────────────┼─────────────────────────────────────────────────┤
│ w.xzdio │ xz default level │
├──────────────┼─────────────────────────────────────────────────┤
│ w7T16.xzdio │ xz level 7 using 16 threads │
├──────────────┼─────────────────────────────────────────────────┤
│ w7T0.xzdio │ xz level 7, autodetect no. of threads │
├──────────────┼─────────────────────────────────────────────────┤
│ w6.lzdio │ lzma (legacy) level 6, lzma's default │
├──────────────┼─────────────────────────────────────────────────┤
│ w19T8.zstdio │ zstd level 19 using 8 threads │
├──────────────┼─────────────────────────────────────────────────┤
│ w7T.zstdio │ zstd level 7, autodetect no. of threads │
├──────────────┼─────────────────────────────────────────────────┤
│ w.ufdio │ uncompressed │
└──────────────┴─────────────────────────────────────────────────┘
