2016-05-24mnesia: Fix index match return patternsDan Gudmundsson
When building match result patterns the tuples they must qouted with { }, which causes a problem with variable patterns. Use element(1, Match) instead of trying to build the two tuple.

2016-05-09mnesia_ext: Create table/data containers from mnesia monitor not temporary ↵Dan Gudmundsson
processes Tables or data containers should be owned and monitored by mnesia_monitor and should thus be created by that process. Always create_table before loading it We need to create tables for ram_copies at least before loading them as they are intermittent. It is also needed to get mnesia monitor as the parent and supervisor of the data storage.
2016-05-09mnesia_ext: Implement ext copies indexUlf Wiger
Make ram_copies index always use ordered_set And use index type as prefered type not a implementation requirement, the standard implmentation will currently ignore the prefered type.

Mnesia didn't forward mnesia_down to transactions which where already decided to be aborted, but that could lead to hanging transactions still waiting for messages from the node which had stopped.

* maint: mnesia: let loader check if tablelock is needed mnesia: Avoid deadlock possibility in mnesia:del_table_copy schema
2016-02-09mnesia: let loader check if tablelock is neededDan Gudmundsson
move_table_copy needs the lock that was set previously in del_table_copy. This doesn't work on old nodes, so bump protocol version and check it. Remove old protocol conversion code, which have been around since OTP-R15. Checking if lock is needed requires rpc communication via mnesia_gvar ets table to be backwards compatible.
2016-02-05mnesia: Avoid deadlock possibility in mnesia:del_table_copy schemaDan Gudmundsson
del_table_copy grabs a write lock in a new process in prepare_op/3 to change 'where_to_read' when a table copy is updated. When del_table_copy(schema, Node) is called all copies located on Node are deleted, and thus many locks are taken. Since this was done outside of the schema-transaction, mnesia's deadlock prevention algorithms was sidestepped and a deadlock could occur. Fix by always grabbing write-locks for all changed tabs early and in the same transaction, this might slow done the operation some but it must be done and it also cleans up the code.

2015-09-10mnesia: Improve index updatesDan Gudmundsson
There is no need to update the index table if a record is updated in non indexed field. This removes one timing glitch where dirty_index_read would return an empty list for records that where updated. There is still an issue with dirty_index_read when updates are made to the index field, it have been reduced but the real table updates are made after the index table references have been added. Originally reported by Nick Marino in erl-questions mailing list, thanks.

2015-05-31mnesia: don't delete log file on emfile errorMikael Pettersson
If the VM runs into the process' file descriptor limit when mnesia tries to open (not create) a disk_log file, the open fails with an emfile error. Mnesia misinterprets this as a corrupt file, deletes it, tries to create a new empty disk_log file, which also fails. The end result is a corrupt database on disk. Check for emfile errors and error out immediately without deleting the file in those cases.
