Mnesia should always use the local context if available OTP-15550
2019-01-22Optimise ext table dumpingDániel Szoboszlay
The original algorithm first grouped ops in a commit by ext engine type via folding over the list with orddict:append/3, that resulted in an O(n^2) algorithm. However, grouping the ops is not needed, the ops can be dispatched to insert_op/6 one-by-one, after looking up the storage semantics of their respective engine. This is a much cheaper algorithm, assuming looking up the storage semantics is cheap (which should be).

Do not read from (set | order_set) source table if the content is already in the transactional context (i.e., a previous write/delete).

Index records for bag tables with ram_copies was not deleted after "real" objects where deleted and thus a memory leak.

Allow to add replicas even if all other replicas are down when the other replicase are not stored on disk.
2018-08-08Do NOT disc_load from ram_copies when master_node is setDan Gudmundsson
Setting master_nodes to a node with ram_copies replica and that node had not loaded the table, could cause it load an empty table, even though (non master) nodes had disc_replicas. This meant that tables where unexpected empty after multiple failures happened. When this happen do not load the table and wait for user to force_load it on some node, preferably with a disk copy.

2018-07-03Fix delete_object and write convergence in transaction.Daniil Fedotov
Fix a bug, when delete_object was deleting the record if it was written in the same transaction even if it was written to a different value. To verify: %% Create a set table mnesia:create_table(foo, []). %% Write and delete_object in transaction mnesia:transaction(fun() -> mnesia:write({foo, bar, one}), mnesia:delete_object({foo, bar, not_one}) end). {atomic, [{foo, bar, one}]} = mnesia:transaction(fun() -> mnesia:read(foo, bar) end). Added a section to isolation tests to check for non-matching delete_object requests.

make erlang:process_info/1 not retrieve messages
2018-03-10make erlang:process_info/1 not retrieve messagesMikael Pettersson
process_info/1 retrieves a number of properties related to a process, including the list of messages in its mailbox. This is potentially unsafe if the target process has a large number of queued messages: - there is no a priori upper bound on the amount of memory being allocated to hold that list, and - the loop to retrieve the messages is uninterruptible, so the Erlang scheduler where this executes blocks for the duration We've seen process_info/1 bring down heavily loaded nodes on more than one occasion. At least once it appeared to have blocked the Erlang heart process from executing, causing the external heart to kill the VM. Consequently this removes 'messages' from the list of process_info tags to retrieve for process_info/1. Note that process_info/1 still retrieves 'message_queue_len', and process_info/2 can still retrieve 'messages' when asked to. A few places in the OTP libraries need minor adjustments, since they want 'message_queue_len' but compute it from the length of the list of messages.
