2013-01-15Implement ./otp_build configure --enable-silent-rulesAnthony Ramine
With silent rules, the output of make is less verbose and compilation warnings are easier to spot. Silent rules are disabled by default and can be disabled or enabled at will by make V=0 and make V=1.

* 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

2012-06-18Prevent index from being corrupted if a nonexistent item is deletedBartlomiej Puzon
We have to ensure that we actually delete the last object with a given (key, index) pair before removing the index.

2012-01-31[Mnesia] More optimizationsDan Gudmundsson
If a transaction releases a write, it can be deleted directly since no read locks or other write locks can be present

2012-01-31[Mnesia] First try with ordered_set instead of bagDan Gudmundsson
Switch to ordered_set so match_object matches partially bound keys, more efficient.
2011-12-31Fixes value returned by mnesia_loader:do_get_disc_copy2/4Uwe Dauernheim
Returns the same value for `mnesia_loader:disc_load_table/2' as `mnesia_loader:net_load_table/4' if a table copy can not be found. This patch was stuck as a pull request in GitHub (authored by Uwe Dauernheim): https://github.com/erlang/otp/pull/16

2011-12-07Use the synchronous log_terms instead of alog_terms in mnesia_log:ets2dcd()Richard Carlsson
This avoids the situation where mnesia could dump a very large ets table in its entirety into the message queue of the disk_log process, causing memory blowup and choking the disk logger.
2011-12-07[mnesia] Read record from correct nodeDan Gudmundsson
Read from where_to_read otherwise bad data may read during move_table, where where_to_write is updated before where_to_read and the table is available.
2011-12-06[mnesia] Fixed sticky read lock bugDan Gudmundsson
wread on locks stuck at non-local node could return unexpected value. Thanks to Magnus Henoch who posted a nice testcase showing the bug.

* dgud/mnesia/leaking-log/OTP-9551: [mnesia] Use api to log decisions.
2011-09-19[mnesia] Use dedicated api for clearing tablesDan Gudmundsson
Mainly to correctly clear dets tables. It may also be faster to use the dedicated functions.
2011-09-19[mnesia] Use api to log decisions.Dan Gudmundsson
Instead of just appending decisions to the log, use mnesia_log:log(Decision), it will increment the counter which causes the log to be dumped even if no actual commits are stored on this node. This fixed a bug where the LATEST.log would grow forever on a node which had the schema on disc, but where not involved in any commits.

2011-09-15[mnesia] Mnesia schema merge tested with 2 nodes, r13b04 -> r14b (dev)Ulf Wiger
The do_merge_schema function now converts cstructs from a remote node when it detects that they are different. In order to be compatible the other way around, mnesia_controller:get_cstructs() detects a remote caller, and converts the cstructs before sending them.

2011-08-16emulator: Add a fourth element in exception stacktracesBjörn Gustavsson
This commit is a preparation for introducing location information (filename/line number) in stacktraces in exceptions. Currently a stack trace looks like: [{Mod1,Function1,Arity1}, . . . {ModN,FunctionN,ArityN}] Add a forth element to each tuple that can be used indication the filename and line number of the source file: [{Mod1,Function1,Arity1,Location1}, . . . {ModN,FunctionN,ArityN,LocationN}] In this commit, the fourth element will just be an empty list, and we will change all code that look at or manipulate stacktraces.
