2010-05-21Merge branch 'sv/format_status_error_info' into devErlang/OTP
* sv/format_status_error_info: Add support for the format_status callback to gen_event Extend format_status for gen_server/gen_fsm termination error logging OTP-8630 sv/format_status_error_info When a gen_server, gen_fsm process, or gen_event terminates abnormally, sometimes the text representation of the process state can occupy many lines of the error log, depending on the definition of the state term. A mechanism to trim out parts of the state from the log has been added (using a format_status/2 callback). See the documentation.

2010-05-12Add support for the format_status callback to gen_eventSteve Vinoski
The gen_server and gen_fsm behaviors support the format_status callback to allow developers to specialize how callback module state appears within the return value of sys:get_status and within logged output resulting from abnormal process termination. This patch adds similar support to gen_event. Event handlers that export a format_status/2 function, which is an optional callback, and are registered with an event manager will now have their format_status callbacks invoked when sys:get_status is called on the event manager. The term returned from format_status for this case replaces the default handler state in the sys:get_status return value. This patch also extends gen_event to call an event handler's format_status function (if it exports one) should the handler terminate abnormally. The term returned from format_status is logged in place of the handler's state. This is intended to allow developers to control how much output is logged in the case of abnormal termination. The documentation is appropriately extended and new unit tests are added to cover the new gen_event format_status functionality.
2010-05-12Extend format_status for gen_server/gen_fsm termination error loggingSteve Vinoski
When a gen_server or gen_fsm process terminates abnormally, sometimes the text representation of the process state can occupy many lines of the error log, depending on the definition of the state term. Developers sometimes would like a way to trim out parts of the state from the log if those parts don't contribute to documenting the circumstances of the error, thereby helping to reduce the amount of logged output. Since the format_status callback can already format and specialize gen_server and gen_fsm state for inclusion in the term returned from sys:get_status, this patch extends format_status in a backward-compatible way to also be able to specialize the state logged for abnormal gen_server and gen_fsm termination, and includes new unit tests to verify the new functionality. This patch also eliminates the previous restriction that the status returned by format_status must be a list. It can now be any term. The documentation is extended to cover the new usage for format_status, and it's been improved to recommend a form for the normal case that allows the returned status to fit well with the rest of the term returned by sys:get_status. The documentation is clear that this form is only recommended, not required.

* bg/opt-receive: Test that gen_server:call/2,3 are fast even with a huge message queue erts: Add tests for the receive optimization Update primary bootstrap erts: Implement recv_mark/1 and recv_set/1 for real compiler tests: Cover the error handling code in beam_receive compiler test: Test optimization of receive statements Optimize selective receives in the presence of a large message queue Introduce the new recv_mark/1 and recv_mark/1 instructions Compile tests that communicate with R12 nodes with the r12 option Move p_run/2 to test_lib gen: Inline wait_resp_mon/2 to help the compiler optimize OTP-8623 bg/opt-receive reveive statements that can only read out a newly created reference are now specially optimized so that it will execute in constant time regardless of the number of messages in the receive queue for the process. That optimization will benefit calls to gen_server:call(). (See gen:do_call/4 for an example of a receive statement that will be optimized.)
2010-05-11Merge branch 'bg/beam_lib' into devErlang/OTP
* bg/beam_lib: Remove redundant includes Make beam_lib:cmp/2 stricter OTP-8625 bg/beam_lib The beam_lib:cmp/2 function now compares BEAM files in stricter way. The BEAM files will be considered different if there are any changes except in the compilation information ("CInf") chunk. beam_lib:cmp/2 used to ignore differences in the debug information (significant for Dialyzer) and other chunks that did not directly change the run-time behavior.

2010-05-10gen: Inline wait_resp_mon/2 to help the compiler optimizeBjörn Gustavsson
We are about to introduce a new optimization that requires the creation of a monitor and the following receive statement to be in the same function.
2010-05-06Remove redundant includesBjörn Gustavsson
2010-05-06Make beam_lib:cmp/2 stricterBjörn Gustavsson
The beam_lib:cmp/2 function only compares the executable parts of the BEAM files, not attributes or abstract code. Since the types and specs (used by Dialyzer) are contained in the abstract code, beam_lib:cmp/2 will return 'ok' if the only difference between two BEAM file are in the types or specs. If an Erlang/OTP system is installed in a revision control system, and beam_lib:cmp/2 is used to avoid committing unchanged but newly compiled BEAM files, BEAM files with no other changes than in types or specs may not get updated, which can problems if Dialyzer or the debugger is run. To avoid that problem, change beam_lib:cmp/2 to compare all chunks *except* for the "CInf" chunk. The "CInf" chunk contains the compilation time, compiler options, and compiler version.

2010-04-20Support nested record field access without parenthesesTuncer Ayaz
Original patch from YAMASHINA Hio posted to erlang-patches@ on Tue Jun 12 11:27:53 CEST 2007: http://www.erlang.org/pipermail/erlang-patches/2007-June/000182.html http://fleur.hio.jp/pub/erlang/record2.patch Only had to do minor changes to port the patch to the current R14A development tree. Also added compiler/record_SUITE:nested_access/2 to test nested record access with or without parentheses. With this change the following will work. -record(nrec0, {name = <<"nested0">>}). -record(nrec1, {name = <<"nested1">>, nrec0=#nrec0{}}). -record(nrec2, {name = <<"nested2">>, nrec1=#nrec1{}}). nested_access() -> N0 = #nrec0{}, N1 = #nrec1{}, N2 = #nrec2{}, <<"nested0">> = N0#nrec0.name, <<"nested1">> = N1#nrec1.name, <<"nested2">> = N2#nrec2.name, <<"nested0">> = N1#nrec1.nrec0#nrec0.name, <<"nested0">> = N2#nrec2.nrec1#nrec1.nrec0#nrec0.name, <<"nested1">> = N2#nrec2.nrec1#nrec1.name, <<"nested0">> = ((N2#nrec2.nrec1)#nrec1.nrec0)#nrec0.name, N1a = N2#nrec2.nrec1#nrec1{name = <<"nested1a">>}, <<"nested1a">> = N1a#nrec1.name, N2a = N2#nrec2.nrec1#nrec1.nrec0#nrec0{name = <<"nested0a">>}, N2b = ((N2#nrec2.nrec1)#nrec1.nrec0)#nrec0{name = <<"nested0a">>}, <<"nested0a">> = N2a#nrec0.name, N2a = N2b, ok.
