Description
Monty is to start the merge of InnoDB into MariaDB 10.0.
Note that there is 5.6.5 m8 (http://dev.mysql.com/downloads/mysql/5.6.html) currently available as well as the spring labs release code-named G5 I guess that differs from what is available in 5.6.5 m8 (http://blogs.innodb.com/wp/2012/04/innodb-2012-spring-labs-release/). There are some features in the labs release that aren't in 5.6.5 m8 (like online DDL, more scalability improvements, etc - see the linked blog post). There is source (http://labs.mysql.com/) but maybe no public tree

10.0 tree is here:
https://code.launchpad.net/~maria-captains/maria/10.0-monty
TODO for the tree regarding InnoDB, performance schema and some general things can be found here:
http://bazaar.launchpad.net/~maria-captains/maria/10.0-monty/view/head:/TODO
Status report:
- Current tree is pushed as 10.0-monty.
- All InnoDB tests and most other test pass.
- Performance schema tests fails (that is what I am working on now).
- In this tree there is a TODO file that explains the current state. From the TODO:
----------
State of MERGE between MariaDB 5.5 and MySQL 5.6.5
Featured copied/merged
- storage/innodb/*
- storage/perfschema
- sql/share/errmsg-utf8.txt
- All CF_XXX states in sql_class.h.
- handler error messages.
- Removed timestamp handling from all handler::write and handler::update
methods. - Added PSI_CALLS to handler.cc
Features recoded
- Better error messages
- Added support of timestamps to ha_write and ha_update.
Fetures half done:
- Support for TRANSACTION READ ONLY | READ WRITE
- CF_XXX states added to init_update_queries() but not otherwise used.
Short time TODO:
- Add support for TRANSACTION READ ONLY | READ WRITE in sql_yacc.yy
(support for variable tx_read_only)
- merge hostname.cc / hostname.h
- add support for host_error()
- Enable performance_schema.host_cache in scripts/mysql_system_tables.sql
- Add full support for timestamp. (remove timestamp handling from ha_write())
---------
Adjusting timeline
maria-call 2012-08-12 08:11 < montywi> 10.0 merge is almost done; now only tests failing are some performance schema tables. Should be able to fix that tomorrow.
