"When I run mnesia:first on an empty fragmented table, it tries to access the fragment with the number one beyond the maximum. In the sample code below, I create a table with two fragments, 'foo' and 'foo_frag2', but mnesia tries to access 'foo_frag3':"

That caused a 'log_header' entry to added to the disc_copies tables.
2010-11-15Call chmod without the "-f" flagHolger Weiß
"-f" is a non-standard chmod option which at least SGI IRIX and HP UX do not support. As the only effect of the "-f" flag is to suppress warning messages, it can be safely omitted.

2010-08-18Remove ticket numbers from all vsn.mk filesBjörn Gustavsson
Some application's vsn.mk files contained a list of the ticket numbers fixed in each version. Since that information can be obtained from the notes.xml file or from the merge commits in the git repository (provided that the branch name includes the ticket number), there is no reason to manually maintain that information in the vsn.mk files.

Only real program files should be installed with INSTALL_PROGRAM while scripts should be installed with INSTALL_SCRIPT and data files with INSTALL_DATA.

2010-06-02remove debug printout and accidental variable name reuseUlf Wiger
2010-06-02Allow a user_defined function to wrap mnesia_schema:merge_schema()Ulf Wiger
Mnesia currently notifies the user if it detects a partitioned network, but the options for resolving the situation are limited. In practice, the only safe options are: - set master_nodes and restart one of the affected 'islands' - restart the entire system from backup This patch introduces a way to resolve the situation without restarting any nodes. The key to doing this safely is to lock affected tables and run the merge function inside the same transaction that merges the schema. Otherwise, one transaction will merge the schema, after which writes to the database will be replicated across the (potentially) inconsistent copies; the transaction triggered by the asynchronous inconsistency event will have to race to be the first to access the tables. The normal call to merge the schema is done from mnesia_controller. Previously, this was mnesia_schema:merge_schema(). The new function is merge_schema(UserFun), with the following behaviour: merge_schema(UserFun) -> schema_transaction( fun() -> UserFun(fun(Arg) -> do_merge_schema(Arg) end) end). Where do_merge_schema(LockTabs) will execute the schema merge as before, but also lock all tables in the list LockTabs which have copies on the affected nodes (that is, everywhere the schema table is locked). The effect of this is to allow a wrapper function that calls the merge and, if successful, continues to resolve the inconsistency on the tables, knowing that they have now been locked on all affected nodes. The function that is actually called by the deconflict function is mnesia_controller:connect_nodes(Nodes, UserFun), as in: Tables = tables_to_deconflict(Node), mnesia_controller:connect_nodes( [Node], fun(MergeF) -> case MergeF(Tables) of {merged,_,_} -> deconflict(Tables, Node); Other -> Other end). In the case where the merge fails, it is probably wise to restart from a backup... I have not run the mnesia test suite, as it is not available. I have not updated documentation, as these functions are not documented in the first place.
2010-05-09Enable continuous monitoring of mnesia overload statusUlf Wiger
Mnesia currently issues an event whenever it detects an overload condition. It recognizes two different types of overload: - whenever the message queue of mnesia_tm process grows large - when a log dump interval triggers before the previous dump is done These events could be used to trigger a load regulation mechanism to reduce the load until the condition seizes. The missing piece is that there is no facility to ask mnesia whether the overload condition still exists. This patch implements a couple of functions in mnesia_lib that can be used to sample the overload status. It has been tested in a load regulator component being developed by Erlang Solutions. No mnesia test suites have been run, since they are not available. No documentation has been updated. The functions in mnesia_lib are at any rate undocumented (as are all other functions in that module). A decision would have to be made about whether to provide a documented API on top of these functions. The internal state record of mnesia_recover has been modified. For this reason, a code change hook has been provided.
2010-03-30Merge branch 'mh/doc-loose-lose' into devErlang/OTP
* mh/doc-loose-lose: Fix spelling: "loose" is not a verb
2010-03-30Merge branch 'bd/mnesia-activity-subscription' into devErlang/OTP
* bd/mnesia-activity-subscription: Add mnesia activity subscription message
2010-03-30Add mnesia activity subscription messageBernard Duggan
A process that calls mnesia:subscribe(activity) will receive the message: {mnesia_activity_event, ActivityID, complete} when any activity that caused a change to a database has finished committing its changes. This allows a subscriber to collect messages already available through the mnesia:subscribe({table, ...}) system to group them as completed transactions.
2010-03-26Fix spelling: "loose" is not a verbMagnus Henoch
"Lose" means not "not win", but "loose" means "not tight". Change "loose" to "lose" where appropriate.
