[debian-mysql] Bug#842696: mariadb-10.0: FTBFS on hurd-i386: no hostpath(), but no socket path limitation

Source: mariadb-10.0
Version: 10.0.28-1
Severity: important
User: debian-hurd at lists.debian.org
Usertags: hurd

Hello,

mariadb-10.0 FTBFS on hurd-i386:

# Run testsuite
cd builddir/mysql-test && ./mtr --force --testcase-timeout=30 --suite-timeout=540 --retry=3 --parallel=1 --skip-test-list=unstable-tests  || exit 1 ;
Logging: /<<PKGBUILDDIR>>/mysql-test/mysql-test-run.pl  --force --testcase-timeout=30 --suite-timeout=540 --retry=3 --parallel=1 --skip-test-list=unstable-tests
Too long tmpdir path '/<<PKGBUILDDIR>>/builddir/mysql-test/var/tmp'  creating a shorter one...
 - using tmpdir: '/tmp/fe_74snTmP'

vardir: /<<PKGBUILDDIR>>/builddir/mysql-test/var
Removing old var directory...
Creating var directory '/<<PKGBUILDDIR>>/builddir/mysql-test/var'...
mysql-test-run: *** ERROR: Socket path '/tmp/fe_74snTmP' too long, it would be  truncated and thus not possible to use for connection to  MySQL Server. Set a shorter with --tmpdir=

This is because on GNU/Hurd, perl's $sock->hostpath() can't work since
the path is not recorded in the socket internals. GNU/Hurd doesn't have
any socket path limitation anyway, so the attached proposed patch just
skips the check.

Also, just like on kfreebsd, upstream mariadb didn't define symbols, so
the same workaround applies here, see patch2.

Having mariadb-10.0 built has become very important for the port since a
lot of packages now depend on it through default-libmysqlclient-dev.

Thanks for considering these patches,
Samuel
