* Revert "Merge pull request #7983 from georgebrock/bug7950-squashed"Carlos Antonio da Silva2013-01-151-6/+1
| | | | | | | | | | | This reverts commit 88a296dccc401da143d90cad54b693ff06bf2b58, reversing changes made to 666a7e34f553cef4c8878362eafc79c7e3f310c3. Conflicts: activerecord/CHANGELOG.md Reason: this has been resulting in some hard to track bugs and is introducing a possible breackage in a stable version.

* implements a much faster auto EXPLAIN, closes #3843 [José Valim & Xavier Noria]Xavier Noria2011-12-041-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | This commit vastly reduces the impact of auto explain logging when enabled, while keeping a negligible cost when disabled. The first implementation was based on the idea of subscribing to "sql.active_record" when needed, and unsubscribing once done. This is the idea behind AR::Relation#explain. Subscribe, collect, unsubscribe. But with the current implementation of notifications unsubscribing is costly, because it wipes an internal cache and that puts a penalty on the next event. So we are switching to an approach where a long-running subscriber is listening. Instead of collecting the queries with a closure in a dedicated subscriber, now we setup a thread local. If the feature is disabled by setting the threshold to nil, the subscriber will call a method that does nothing. That's totally cheap.

* implements automatic EXPLAIN logging for slow queriesXavier Noria2011-12-021-16/+29
|
* add the query to AR::Relation#explain outputXavier Noria2011-11-251-2/+3
| | | | | | | Rationale: this is more readable if serveral queries are involved in one call. Also, it will be possible to let AR log EXPLAINs automatically in production mode, where queries are not even around.
* implements AR::Relation#explainXavier Noria2011-11-051-0/+16
| | | | | | | | | | | | | | | | | | | This is a first implementation, EXPLAIN is highly dependent on the database and I have made some compromises. On one hand, the method allows you to run the most common EXPLAIN and that's it. If you want EXPLAIN ANALYZE in PostgreSQL you need to do it by hand. On the other hand, I've tried to construct a string as close as possible to the ones built by the respective shells. The rationale is that IMO the user should feel at home with the output and recognize it at first sight. Per database. I don't know whether this implementation is going to work well. Let's see whether people like it.

* Raise error on unknown primary key.Jon Leighton2011-10-051-3/+3
| | | | | If we don't have a primary key when we ask for it, it's better to fail fast. Fixes GH #2307.
