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.

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.)

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.

2010-05-11compiler test: Test optimization of receive statementsBjörn Gustavsson
We don't attempt to run the generated code, but use beam_disasm and check for the presence or absence (as appropriate) of the recv_mark/1 and recv_set/1 instructions.
2010-05-11Optimize selective receives in the presence of a large message queueBjörn Gustavsson
If a gen_server process has many messages in its message queue and calls another gen_server process, the selective receive in gen_server:call() will have to go through the entire message queue. Have the compiler generate the new mark_recv/1 and mark_recv/1 instructions that can avoid going through the entire message queue.
2010-05-11Introduce the new recv_mark/1 and recv_mark/1 instructionsBjörn Gustavsson
Make the recv_mark/1 and recv_mark/1 instructions known to the compiler and run-time system. For the moment, make the loader ignore any occurrences of those instructions in BEAM files. Also update hipe_beam_to_icode to ignore those instructions.

2010-05-06Merge branch 'sv/sasl-fix-get_status' into devErlang/OTP
* sv/sasl-fix-get_status: Prepare patch release fix sys:get_status backward compatibility for sasl release_handler_1 OTP-8619 sv/sasl-fix-get_status In R13B04 sys:get_status was modified to invoke format_status/2 in the callback module if the module exports that function. This resulted in a change to the term returned from calling sys:get_status on the supervisor module, since supervisor is a gen_server and gen_server exports format_status. The sasl release_handler_1 module had a dependency on the pre-R13B04 term returned by sys:get_status when invoked on a supervisor, so the R13B04 change broke that dependency. This problem has been fixed by change release_handler_1 to handle both the pre-R13B04 and R13B04 terms that sys:get_status can return from a supervisor.

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.

2010-05-05Adjust test of file:del_dir("..") to accept {error,einval}Björn Gustavsson
On FreeBSD, file:del_dir("..") will return {error,einval} rather than the expected {error,eexist}, and so will file:del_dir("../.."), and so on. It could be argued that we should change the implementation of file:del_dir/1 to remap the error code (as some other error codes are remapped to reduce the differences between different platforms), but the consistency gained does not seem to be worth the effort. Therefore, until we'll find a real-world use case where it is essential to have consistent error codes for file:del_dir("..") on all platforms, change the test case to accept both errors.

2010-05-05fix sys:get_status backward compatibility for sasl release_handler_1Steve Vinoski
In R13B04 sys:get_status was modified to invoke format_status/2 in the callback module if the module exports that function. This resulted in a change to the term returned from calling sys:get_status on the supervisor module, since supervisor is a gen_server and gen_server exports format_status. The sasl release_handler_1 module had a dependency on the pre-R13B04 term returned by sys:get_status when invoked on a supervisor, so the R13B04 change broke that dependency. Change release_handler_1 to handle both the pre-R13B04 and R13B04 terms that sys:get_status can return from a supervisor.

Packet handling was sort of broken but would mostly work as expected when socket was in binary mode. This has now been fixed.
