This document describes the changes made to the Mnesia system + from version to version. The intention of this document is to + list all incompatibilities as well as all enhancements and + bugfixes for every release of Mnesia. Each release of Mnesia + thus constitutes one section in this document. The title of each + section is the version number of Mnesia.

+ +
Mnesia 4.3.7 +
Fixed Bugs and Malfunctions + + +

+ Removed a memory leak on ram-only nodes, introduced in + mnesia-4.3.6.

+

+ + +
+
+ Known Bugs and Problems + + +

+ + +
+ +
+ + +
+ Mnesia 4.3.6 + +
Fixed Bugs and Malfunctions + + +

+ A bug causing lots of records to be lost at startup from + an installed fallback has been fixed. The bug did however + not show up when a backup file generated with + mnesia:backup/1 or + mnesia:backup_checkpoint/2 was installed as + fallback. In order to trigger the bug, the items in the + backup file had to be rearranged in such an order that + records from different tables were interleaved with each + other.

+

+ Own Id: OTP-6903 Aux Id: seq10763

+ + +

+ Mnesia sometimes failed to commit schema operations on + all nodes, this have been seen on smp machines but could + happen on single processor as well with some bad timing.

+

+ Own Id: OTP-6904

+ + +

+ mnesia:select/1 failed to return all matches on + remote nodes if something was written to the table + earlier in the same transaction.

+

+ Mnesia 4.3.5 + +
+ Fixed Bugs and Malfunctions + + +

The internal index tables on bag tables where not always + cleaned correctly. Thanks Christopher Faulet and Salazard + Remy.

+

Own Id: OTP-6587

+ + +

Changing the copy type with + mnesia:change_table_copy/3 on a node which was down + was not handled correctly, that caused an eternal table + lock on the alive nodes. Thanks Hal Snyder.

+ Known Bugs and Problems + + +

Rearranging fragmented tables is an O(N^2) + operation.

+
+ +
+ Mnesia 4.3.4 + +
+ Fixed Bugs and Malfunctions + + +

Adding fragments to ram_copies tables was allowed on + nodes that where down.

+

Own Id: OTP-6367

+ + +

Mnesia leaked transaction decisions (memory and disk + space).

+

Own Id: OTP-6464

+ + +

dirty_update_counter/3 did not work properly on + disc tables when the counter was not initiated (Thanks to + Sebastien Saint-Sevin).

+

Own Id: OTP-6545

+ + +

Chunked mnesia:select on fragmented tables could + crash (Thanks to Primanathan Reddy).

+

Own Id: + OTP-6548

+ + +
+ +
+ Improvements and New Features + + +

Introduced a new configure parameter dc_dump_limit.

+

Removed dead code (dialyzer warnings) and debugging + features that called interpreter commands.

+

Minor + performance increase when a lot of simultaneous + transactions where active.

+

Thank you Scott Lystig + Fritchie for debugging and bug reports.

+
+ +
+ Mnesia 4.3.2 + +
+ Fixed Bugs and Malfunctions + + +

Mnesia sometimes failed to remove [d]ets table fixation, + when using mnesia:first/1,mnesia:next/2 or + qlc this could cause that deleted records are not + actually deleted in the [d]ets table and that + mnesia:[dirty_]first/1 reported the wrong key.

+

Own Id: OTP-6193 Aux Id: seq10376

+ + +
+
+ +

+ Improvements and New Features + + +

Added parallel table loaders to increase startup + performance when the system have many small tables. The + configuration variable no_table_loaders configures + the number of loaders, default is two.
