* Add ActiveRecord::Base#with_lockOlek Janiszewski2012-01-181-1/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | Add a `with_lock` method to ActiveRecord objects, which starts a transaction, locks the object (pessimistically) and yields to the block. The method takes one (optional) parameter and passes it to `lock!`. Before: class Order < ActiveRecord::Base def cancel! transaction do lock! # ... cancelling logic end end end After: class Order < ActiveRecord::Base def cancel! with_lock do # ... cancelling logic end end end

* Allow to run migrations with given scope, with SCOPE=<scope>Piotr Sarnacki2011-12-091-0/+12
| | | | | | | | | | | Scope in migrations can be defined by adding suffix in filename, like: 01_a_migration.blog.rb. Such migration have blog scope. Scope is automatically added while copying migrations from engine, so if you want to revert all of the migrations from given engine, you can just run db:migrate with SCOPE, like: rake db:migrate SCOPE=blog
* removes the convenience instance version of AR::Base.silence_auto_explainXavier Noria2011-12-031-2/+2
| | | | | | | Rationale: As discussed with José and Jon, this convenience shortcut is not clearly justified and it could let the user thing the disabled EXPLAINs are related to the model instance rather than being globally disabled.

* implements AR::Relation#explainXavier Noria2011-11-051-0/+2
| | | | | | | | | | | | | | | | | | | 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.

* Convert CHANGELOGs to Markdown format.Jon Leighton2011-11-041-0/+6564
Reasons: * Markdown reads well as plain text, but can also be formatted. * It will make it easier for people to read on the web as Github formats the Markdown nicely. * It will encourage a level of consistency when people are writing CHANGELOG entries. The script used to perform the conversion is at https://gist.github.com/1339263
