Michal Schorm c9a1954897 Implement running of the minimal testsuite
Once the full testsuite has been run for the particular MySQL release; execute just the "main" suite on subsequent runs for that release.

The implementation default to running of the whole testsuite, as until now, if the maintainer won't set the flag that running of the minimal testsuite is enough for this release.

This feature aims to help with faster and more stable package builds when adding small fixes on top of already tested release;
and to ease the life of Fedora Linux Release Engineers during (mass) rebuilds.

Avoid errors like:
| Path length (109) is longer than maximum supported length (108) and will be truncated at /usr/lib64/perl5/vendor_perl/Socket.pm line 880, <GEN16094> line 1.
| worker[2] mysql-test-run: *** ERROR: Socket path '/builddir/build/BUILDROOT/mysql-8.0.24-1.fc35.s390x/usr/share/mysql-test/var/tmp/2' too long,
| it would be truncated and thus not possible to use for connection to MySQL Server. Set a shorter with --tmpdir=<path> option
===
On Fedora 32:
| $ grep -e "PATH" /usr/include/linux/limits.h
| #define PATH_MAX 4096 /* # chars in a path name including nul */
===
Thus setting the maximum path length on Fedora to 108 characters is just too short.
BTW on the modern filesystems you can easily create path longer than PATH_MAX.
The PATH_MAX constant is unsafe.

The question is why haven't I encountered this issue until recently ?
After the recent tweaks to the testsuite (between 8.0.24 and 8.0.25 release), the generated --tmpdir path changed from
| --tmpdir=/builddir/build/BUILD/mysql-8.0.24/x86_64-redhat-linux-gnu/mysql-test/var/tmp/
to
| --tmpdir=/builddir/build/BUILDROOT/mysql-8.0.24-1.fc35.x86_64/usr/share/mysql-test/var/tmp/
===
The whole setup changed as follows:

===
The likely cause is the added
| cd %{buildroot}%{_datadir}/mysql-test
which was not originally present in the SPECfile.
However the MariaDB implementation does not have this issue, even though it has the same SPECfile %check phase code.
===
In the extended log, you can see '/tmp/XfTFAis2Jl' being created and deleted short after.
Even though the script warns about the path length, tries to workaround it; it destroyes that workaround short after and use the too-long path instead.
I'm not sure whether the output is synchronous, but even if it wasn'tit still looks weird.
