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 4.4.12 + +
Improvements and New Features + + +

+ The documentation is now built with open source tools + (xsltproc and fop) that exists on most platforms. One + visible change is that the frames are removed.

+
Mnesia 4.4.11 + +
Improvements and New Features + + +

+ Fixed duplicate results with mnesia:index_read() on + ordered_set tables. Reported by Sam Bobroff.

+

+ Fixed locking in mnesia:index_read() which now grabs a read + table lock to ensure correctness, this may slow down the + operation or block other processes trying to reach the + same table.

+

+ Calling mnesia:dump_log() could crash mnesia, + Reported by Igor Ribeiro Sucupira.

+

+ Own Id: OTP-7585 Aux Id: seq11046

+ + +
+
+ +
Mnesia 4.4.5 +
Improvements and New Features + + +

+ mnesia:clear_table/1 does not require that all + replicas of the table are available anymore.

+

+ Own Id: OTP-7466 Aux Id: seq11015

+ + +
+
+ +
Mnesia 4.4.4 + +
Fixed Bugs and Malfunctions + + +

+ Mnesia did not garbage collect transaction decisions on + disk based nodes if no transactions where made on the + local node.

+

+ Own Id: OTP-7419

+ + +
+ +
+ +
Mnesia 4.4.3 + +
Fixed Bugs and Malfunctions + + +

+ Table referred to by foreign key did not have node_pool + properly cleaned up when a node was removed from the + schema. Thanks Paul Mineiro.

+

+ Own Id: OTP-7340

+ + +

+ Mnesia crashed and generated a core dump if a + schema_transaction was running when mnesia stopped.

+

+ Own Id: OTP-7378 Aux Id: seq10964

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

+ It is now possible to delete a db node even when other + disk resident nodes are down. Thanks Paul Mineiro.

+

+ Own Id: OTP-7383

+ + +
+ +
+ +
Mnesia 4.4.2 +
Fixed Bugs and Malfunctions + + +

+ Sticky locks could lead to hanging transactions.

+

+ Own Id: OTP-7205 Aux Id: seq10793

+ + +

+ mnesia:snmp_get_next_index/2 didn't work with + partial index keys. Argument checking is now done + according to documentation, in functions + mnesia:snmp_get_row/2, + mnesia:snmp_get_mnesia_key/2 and + mnesia:snmp_get_next_index/2. These functions now + require that RowIndex is a list.

+

+ + +
+
+ +
Mnesia 4.4.1 +
Fixed Bugs and Malfunctions + + +

+ Snmp index tables was not initialized correctly in + mnesia-4.4.

+

+ Own Id: OTP-7170 Aux Id: seq10870

+ + +
+
Known Bugs and Problems + + +

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

+

+ Own Id: OTP-6300

+ + +
+
+ +
Mnesia 4.4 +
Fixed Bugs and Malfunctions + + +

+ Mnesia ignored the module argument to + mnesia:restore/2. Thanks Paul Minerio.

+

+ Own Id: OTP-6981

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

+ Mnesia's snmp operations snmp_get_row/2, + snmp_get_next_index/2 and + snmp_get_mnesia_key/2 have been made context + aware, i.e. inside a transaction they will compensate for + table updates made in earlier in the same transaction. + This might cause a performance drop if a lot of updates + have been made before the invocation of these functions.

+

+ *** POTENTIAL INCOMPATIBILITY ***

+

+ Own Id: OTP-6856 Aux Id: seq10671

+ + +

+ Introduced erlang:phash/2 as new default for fragmented + tables. Already existing tables will continue to use + whatever hash function they where using.

+

+ Own Id: OTP-6923

+ + +

+ Introduced mnesia:is_transaction/0.

+

+ Own Id: OTP-6995 Aux Id: seq10812

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

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