[debian-mysql] Fwd: [JIRA] (MDEV-5707) MTR fails on kfreebsd

[Otto Kekäläinen]

Hello James,

I've reported the build fail issues on different archs to upstream. I
got this request below to temporarily apply a patch and re-build to
get debugging info.

Did you as DD have access to the build machines and have possibility
to do this kind of test runs?
Or should I just apply this to git head and wait until you upload
5.5.35-2 or something?

---------------------------------------

I don't see anything obvious in MTR that could cause the difference
between MySQL and MariaDB, the fragments of code that do the check for
socket path length are identical.
If you could apply (temporarily!) the patch below, we might gather
more information about what is going on. The patch itself cannot fix
anything, it just adds more logging.

> As seen at https://buildd.debian.org/status/package.php?p=mariadb-5.5 the Debian MariaDB packages do not build on architecture kfreebsd (both i386 and amd64). Builds fail with the error:
> {noformat}
> mysql-test-run: *** ERROR: Socket path '/tmp/0rfd4fI37_' too long, it would be  truncated and thus not possible to use for connection to  MySQL Server. Set a shorter with --tmpdir=<path> option
> {noformat}
> Equivalent MySQL packages build successfully as seen on https://buildd.debian.org/status/package.php?p=mysql-5.5
> Maybe there are some patches in MySQL that could be imported into MariaDB?
