2016-03-17mnesia: Send mnesia_down messages to waiting transactionsDan Gudmundsson
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.

'dumbbell/mnesia-hang-if-remote-stopped-after-proto-negotiation' into maint * dumbbell/mnesia-hang-if-remote-stopped-after-proto-negotiation: mnesia: Check nodes after protocol negotiation OTP-12473
2015-02-10mnesia: Check nodes after protocol negotiationJean-Sébastien Pédron
During Mnesia startup, after protocol negotiation, the list of connected nodes is written to "recover_nodes". This list is later used to merge the schema. If Mnesia was stopped on a remote node between the protocol negotiation and the moment the list is stored in "recover_nodes", the remote node is still considered running: the value of "recover_nodes" stored during mnesia_down/1 is overwritten. Therefore, this node may be used to acquire a write lock on the schema in order to perform the merge. In this case, the remote node never answers to the lock request and Mnesia hang forever (application:start(mnesia) never returns). To fix the problem, we check the list one last time and remove from it all nodes where Mnesia is stopped. And because there is still a chance for missing mnesia_down event, handle_cast({mnesia_down, ...}, ...) writes to recover_nodes again, in addition to mnesia_down/1.
