Socket file path is too long

[sbelov]

If the maven module is built in a deep enough directory location, and <data/> configuration setting points to somewhere inside ${project.build.directory} (which is the default), MySQL will not start due to failure to open a Unix socket (see below).

A workaround is to point <data/> to a fixed location with a shorter path (say, under /tmp). But I'd still like to be able to have my data under ${project.build.directory}, so that all mysql files are properly deleted on executing mvn clean.

Proposed solution: socket file location should be a configuration option with a sensible default.

@sbelov take a look: #10 Does it help?

[sbelov]

I believe it should work for me - will try it out; I think adding a
socketFile configuration parameter to the plugin is still a reasonable idea
though.

Thanks!

yeah, totally agree. would you be interested to submit a pull request?

After moving mysql data under /tmp, following the advice in #10 , I found that Hibernate started giving errors like these:

WARN  [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (default task-50) SQL Error: 1146, SQLState: 42S02
ERROR [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (default task-50) Table 'root.HT_HDocument' doesn't exist
WARN  [org.hibernate.hql.spi.TemporaryTableBulkIdStrategy] (default task-50) unable to drop temporary id table after use [Unknown table 'HT_HDocument']
...
Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'root.HT_HDocument' doesn't exist

So I created a patch to let me put just the socket file under /tmp: #51.

I'm having trouble reproducing the temp table problem I mentioned above, so it might not have been related to putting mysql-data under /tmp. I'm not sure.

In any case, #51 has just been merged, for what it's worth. Thanks @yegor256

@seanf version 0.9 is in Maven Central already. many thanks for your contribution!

@sbelov please close the issue if the solution is good enough

@sbelov ping...

FWIW, I did see the temp table problem (#50 (comment)) again, but not since I started using the new <socket> parameter. Moving the data out of /tmp seems to have helped.
