There is (and it's been there for a few months already) a new version (5.1.60) of mariadb on the mariadb site. An ebuild (even in the overlay) would be nice. I don't know (and I can't check at the moment) if a simple rename would do the trick.

MariaDB 5.1.62 is now in the overlay.
A patch from mysql-extras needs a change so please use the updated info.

MariaDB 5.1.62 is now in official tree as unstable
RESOLVED FIXED?

Please run the testsuites. I'm not 100% happy with it.

Could it be because I have /var/tmp/portage on a tmpfs?

Nope, same errors on a real filesystem as well.

I've discovered that ma_test_all-t fails with -O2 or -Os in C(XX)FLAGS set.

They work fine if -O1 is set.

I've pointed this out on the MariaDB mailing list, but not sure if it's a MariaDB bug or gcc optimization issue.

@Robin: Do we need to force -O1 for tests only or should we always do it?

I get the same test failures but they are not new since I get exactly the same test cases failing with version 5.1.50.

Re: Aria unit tests fail at ma_test2 line 316
From what I see, ma_test2 has the array key3[5000], used in a loop which sets

n3=rnd(5000);
and then reads
key3[n3] == ...

while rnd(uint max_value) is
return (uint) ((rand() & 32767)/32767.0*max_value);

which means with some luck it can return max_value itself.

Luck happens, rnd returns 5000, key3[n3] reads something entirely wrong (in my case the value of 'silent' variable which is int and set to 1 as the unit test is launched with -s), the entire condition check with key3[n3] gets twisted, the bogus error occurs.

The following change fixes the problem for me, although maybe there are more elegant solutions.

Fix index errors in the ma_test2 unit test binary

This patch fixes the errors on ma_test2 during unit tests.
It appears randomly due to the rnd function returning a random number between and including 0 to 5000. Since there are 5000 entries in the array, if rnd() pulls 5000, it's out of bounds.

When applied, my test box passes all tests with the following parameters.
FEATURES="test userpriv -usersandbox" USE='-cluster -latin1 embedded extraengine perl ssl community'

This also applies and fixes on mariadb-5.2.12 and mariadb-5.3.6.

5.2.12 only 1 test fails (plugins.unix_socket) due to Portage stripping $USER.
5.3.6 has the same test failure due to Portage

Re: Aria unit tests fail at ma_test2 line 316
I've attached a patch which helped me resolve the random test failures.

There is a second spot for a possible index out of range that was not previously reported.

Patch is now InCVS and will ship with the next mysql-extras release.

Launchpad bug id: 986261

This was a bug in the test case (not aria); One array was one unit too small.

I will push this into 5.1, 5.2, 5.3 and 5.5

Fix pushed into 5.1
