2013-11-28Fix race condition in mnesia_monitorJonas Falkevik
Mnesia_monitor detect mnesia down using a remote process link and net_kernel nodeup to detect that a node are reacable again. If there is a short node communication problem. The node-down and node-up events can happen before the remotely linked process generates an 'EXIT'. When node-down and node-up events are recevied they are stored and later checked if the node came up just before mnesia flagged the node as down.
2013-11-25mnesia: Synchronize lock cleanup after mnesia downDan Gudmundsson
Bad timing could lead to hanging transactions after a mnesia down from a node with sticky locks. Excellent bug report from janchochol Situation: * node A and B have copies of table T * node A ows sticky of table T * node A goes down (e.g. crash) * node B tries to perform transactional operation on table T (e.g. mnesia:select) In this situation there is possibility that first (and maybe other) transaction on node B will hang indefinitely. This is caused by race condition, when transaction process send lock request operation to node A and waits for reply. When node A is down it will never send reply, so process on node B will be stuck forever. Reason is that message sent to mnesia_locker gen_server from mnesia_locker:mnesia_down can be received after mnesia_locker gen_server already replies to transaction processes with {switch, N, Req} and node N is down. Monitoring remote process when sending request to other node should be safe solution.

Fixed a race where some parts of a transaction could be added to the checkpoint. There are probably more races here but this improves the current testcases.

The previous commit contained a regression that would trigger a crash when attempting to add an index to an Mnesia table of type ordered_set.

2013-04-12Optimize index creation for Mnesia set tablesNick Marino
ETS bag tables have very poor performance on insertion if you have lots of rows with duplicate keys, since it has to check each existing record and make sure it's not inserting any duplicates. This can lead to some pretty drastic slowdowns when inserting lots of rows into an Mnesia table, IF you're introducing lots of duplicate values into an indexed column. As it turns out, we can fix this by switching to duplicate_bag tables for storing Mnesia indexes on tables of type 'set', and it ultimately makes no functional difference since we will never actually attempt to insert any duplicate records anyway. (We would have to make some bigger changes to make this work for Mnesia bag tables though, so that is left as a possible enhancement for the future.)
2013-04-11mnesia: Fixed bad data in tableDan Gudmundsson
If mnesia:cleartable/1 was called during a table_load an schema event with delete and write of that table is sent, which caused the table to contain the schema record instead of clearing the table.

* ao/fix_mnesia_overload_msg_format: Fix format of mnesia overload message OTP-10639
2012-10-11Fix format of mnesia overload messageAhmed Omar
Using ~p in mnesia overload message could lead to wrong messages. mnesia_tm overload message contains a list of two numbers (queue length) example: instead of: Mnesia is overloaded: {mnesia_tm,message_queue_len,[100,105]} it prints : Mnesia is overloaded: {mnesia_tm,message_queue_len,"di"} Replacing ~p with ~w fixes the problem as it doesn't try to detect lists of printable characters
2012-10-01mnesia: Use chained send_after instead of send_intervalJames Wheare
timer:send_interval behaves badly when resuming from sleep on some platforms. For example, if I sleep for 10 minutes, and have a send_interval running once per minute, when I resume, 10 messages will be sent immediately, eliminating the benefit of only running the work periodically. This is admittedly a separate bug with send_interval, but the workaround is straightforward, and also protects from messages piling up in the queue when the work takes longer than the interval. This patch fixes piled up error reports on resume from sleep: ** WARNING ** Mnesia is overloaded: {dump_log, write_threshold} You'll still be warned if mnesia is overloaded, just not repeatedly. Additionally, erlang:send_after is more efficient than using the timer module equivalent [1] [1] http://www.erlang.org/doc/efficiency_guide/commoncaveats.html#id57251
