* 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.

The documentation of lists:keysort/2 states that the sort is stable.
|
|
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.

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.)
|
|
* 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.
|
|
|
|
R12 nodes cannot load code that use the optimized receive that
we are about to implement.
|
|
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.
|
|
|
|
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.

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.
