Description
Add support for MariaDB to Stash
Currently Stash supports MySQL as described in the Supported platforms. However, Stash is not tested against variants of MySQL like Percona and MariaDB. For support, you should switch to a normal MySQL installation as per the document's description.
This issue intends to engage us on a research about the viability of adding full support to MariaDB.
Currently we mapped two scenarios:
Scenario 1
When trying to upload to a Git repository, the following error is displayed:
[xxx@attlasin_server git_project]# git push origin master
Password:
Counting objects: 21183, done.
Delta compression using up to 3 threads.

remote:
remote: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Specified key was too long; max key length is 767 bytes
Workaround for Scenario 1
- Find query in the log:
2013-10-25 16:55:01,169 ERROR [threadpool:thread-7] marek.knappe 1014x21271x1 1vmdfi9 122.99.118.175 "POST /scm/cg/compass-gateway.git/git-receive-pack HTTP/1.1" net.java.ao.sql Exception executing SQL update <CREATE INDEX index_ao_6978bb_res847341420 ON AO_6978BB_RESTRICTED_REF(REF_VALUE)>
- Execute the query manually:
MariaDB [ecc_stash]> CREATE INDEX index_ao_6978bb_res847341420 ON AO_6978BB_RESTRICTED_REF(REF_VALUE); Query OK, 0 rows affected, 1 warning (0.06 sec) Records: 0 Duplicates: 0 Warnings: 1
- Probable root cause:
It's likely that 1 warning part is the culprit. The JDBC driver probably doesn't differentiate between warnings and errors, so either is probably treated as the SQL statement failing.
Scenario 2
"An error occurred" pops up on all repo pages. The details state "An error occurred while processing the request. Check the server logs for more information."

Workaround for Scenario 2
At the moment the immediate workaround is to disable the Ref Syncing plugin that is affected by this error. To do that, go to Administration -> Manage Add-ons and select 'Show all' in the drop-down for filtering plugins. Find a plugin named Atlassian Stash Repository Ref Synchronizer and disable that plugin. This should cause the error to disappear from your repository pages.
