-This library provides extensions to Rails' ActiveRecord adapters.
+AdapterExtensions add extra abilities to Rails ActiveRecord adapters, including:
-As of version 0.9.5, adapter_extensions has dependencies on ActiveSupport and ActiveRecord 2.1.x or higher.
+* bulk load
+* truncate table
+* copy table
+* add select into table
+
+### Compatibility matrix
-### How to test
+See Travis for up-to-date info: [](http://travis-ci.org/activewarehouse/adapter_extensions)
-Currently tested on MySQL and Postgres.

-#### Testing on MySQL
+### Important notes on MySQL support
-see `test/connection/mysql/connection.rb` and tweek if needed, then:
+#### Security warning
- mysql -u root -p -e "create database adapter_extensions_unittest"
- rake test
-
-One test should fail with 'known issue with MySQL' (see commit 75da4b08).
+Be sure to first read and understand the [security implications](http://dev.mysql.com/doc/refman/5.0/en/load-data-local.html) of `LOAD DATA LOCAL INFILE`. In particular, having this enabled on a web app is probably not a good idea.
-#### Testing on Postgresql
+#### v0.9.5
-see `test/connection/postgresql/connection.rb` and tweek if needed, then:
+v0.9.5 will always use `LOAD DATA LOCAL INFILE` for bulk load - this is not configurable.
- createdb adapter_extensions_unittest
- rake test DB=postgresql
+#### v1.0.0.rc1
+
+This version should by default use `LOAD DATA INFILE` for safer defaults.
+
+You can override this by passing `:local_infile => true` though.
+
+#### Troubleshooting LOCAL INFILE
+
+If you enable `:local_infile => true` and meet the following error, then you'll have to work it around.
+
+```
+The used command is not allowed with this MySQL version: LOAD DATA LOCAL INFILE
+```
+
+For mysql2 with AR >= 3.1:
+
+- use [this fork](https://github.com/activewarehouse/mysql2) until [this pull-request](https://github.com/brianmario/mysql2/pull/242) is merged
+- add `local_infile: true` to your database.yml
+
+For mysql2 with AR < 3.1:
+
+- no current easy solution afaik
+
+For mysql:
+
+- try this [untested patch](https://github.com/activewarehouse/adapter_extensions/issues/7)
+
+### Notes on SQLServer support
+
+v0.9.5 had a broken support for SQLServer.
+
+v1.0.0.rc1 has a work-in-progress bulk import using `freebcp`. More tweaking needed.
+
+### Running the tests
+
+You may have to tweak the Rakefile and database.yml a bit, but roughly:
+
+```
+rake ci:create_db
+rake "ci:run_one[mysql2,test/config/gemfiles/Gemfile.rails-3.2.x]"
+```
+
+You can also run a matrix of tests using:
+
+```
+rake ci:run_matrix
+```
