Subject: [PATCH] Fix compression tests
Existing compression tests used tar with compiled-in defaults. However,
some of the defaults are sure to create archives that are not byte-to-byte
reproducible (e.g. DEFAULT_ARCHIVE_FORMAT=POSIX, because the name field
in posix extended headers uses PID of the creating process by default).
Moreover, some compressors (e.g. gzip) store current timestamp in
the file header when compressing from stdin, so that using cmp on the
two created archives as the tests did is error-prone. Another problem
is that the tests implicitly assumed that tar uses archive suffix to
recognize its format when extracting, which isn't the case. Finally,
there's hardly any reason in using sed to create m4 sources, when
everything can be achieved by m4 itself.
* tests/Makefile.am: Remove generation of compress-*.at files.
* tests/compress.at.in: Remove.
* tests/compress.m4: New file.
* tests/testsuite.at: Include compress.m4, use TAR_CHECK_COMPRESS to
check compression options.
