* Make connection pool fair with respect to waiting threads.Patrick Mahoney2012-05-251-1/+1
| | | | | | | | | | | | | | | The core of this fix is a threadsafe, fair Queue class. It is very similar to Queue in stdlib except that it supports waiting with a timeout. The issue this solves is that if several threads are contending for database connections, an unfair queue makes is possible that a thread will timeout even while other threads successfully acquire and release connections. A fair queue means the thread that has been waiting the longest will get the next available connection. This includes a few test fixes to avoid test ordering issues that cropped up during development of this patch.

| | | | | | | | | | | | This reverts commit d2901f0fc4270a765717ad572d559dc49a56b3a8, reversing changes made to 525839fdd8cc34d6d524f204528d5b6f36fe410c. Conflicts: activerecord/test/cases/connection_pool_test.rb Reason: This change broke the build (http://travis-ci.org/#!/rails/rails/builds/1391490) and we don't have any solution until now. I asked the author to try to fix it and open a new pull request.

| | | | RUNNING_UNIT_TESTS file for details, but essentially you can now configure things in test/config.yml. You can also run tests directly via the command line, e.g. ruby path/to/test.rb (no rake needed, uses default db connection from test/config.yml). This will help us fix the CI by enabling us to isolate the different Rails versions to different databases.
