2012-11-30erts: Change default of erl_crash.dumpBjörn-Egil Dahlberg
* Create an erl_crash.dump if no heart exists and no ERL_CRASH_DUMP_SECONDS is set (behaviour changed) * Don't create an erl_crash.dump if heart do exists and no ERL_CRASH_DUMP_SECONDS is set (behaviour not changed) This changes the behaviour back to the R15B02 default considering if a beam was running with no heart. The motivation is that we want a fast heart to fast restart erlang if it crashes but to be able to get non-truncated erl_crash.dumps via setting ERL_CRASH_DUMP_SECONDS if we so desire.

* egil/fix-crash_dump-lc-assert: erts: Suppress lock assertion when dumping a crash
2012-11-22Teach erts_bs_append not to dump corePatrik Nyblom
When erts_bs_append() calls the garbage collector, it has set the PB_ACTIVE_WRITER flag in the ProcBin for the binary object is about to be appended to. Therefore, it is expected that the garbage collector should neither move nor shrink the binary object. But if the garbage collector does a minor collection (thereby clearing the PB_ACTIVE_WRITER flag in the ProcBin) and there is still not enough heap space, there will be a second major garbage collection. During the major collection (since the the PB_ACTIVE_WRITER flag was cleared), the binary object may be shrunk or moved (depending on sizes and how many other writable binaries there are in the process). Avoid the problem by clearing the PB_ACTIVE_WRITER flags in a separate pass after the garbage collection(s). Thanks to Denis Titoruk for helping us find this bug.

2012-11-05Fix binary append exceptionsBjörn Gustavsson
Code such as the following should cause an exception: Bin = <<0:1>>, <<Bin/binary,...>> (Because the "binary" type implies that the binary must have a size in bits that is a multiple of 8.) Depending on the binary, either no exception was thrown or the wrong exception was thrown (because c_p->freason was not set). Noticed-by: Adam Rutkowski

2012-10-16erts: Change ERL_CRASH_DUMP_SECONDS behaviourBjörn-Egil Dahlberg
Not setting ERL_CRASH_DUMP_SECONDS will now terminate beam immediately on a crash without writing a crash dump file. Setting ERL_CRASH_DUMP_SECONDS to 0 will also terminate beam immediately on a crash without writing a crash dump file, i.e. same as not setting ERL_CRASH_DUMP_SECONDS environment variable. Setting ERL_CRASH_DUMP_SECONDS to a negative value will let the beam wait indefinitely on the crash dump file being written. Setting ERL_CRASH_DUMP_SECONDS to a positive value will let the beam wait that many seconds on the crash dump file being written. A positive value will set both an alarm in beam AND a heart timeout for restart if heart is running. This is due to the change of 'heart' behavior when 'heart' is listening for a crash.

2012-08-27make_preload: Don't fail if Perl's default file encoding is UTF-8Björn Gustavsson
Setting Perl's default encoding for files to UTF-8, for example like this: PERL_UNICODE=DS make would crash the build with a message similar to: form size 1413 greater than size 1237 of module at utils/make_preload line 175, <FILE> chunk 1. Tell Perl to interpret the data in BEAM files as binary by using the binmode() function. The binmode() function existed before Unicode support was added to Perl, which means that make_preload should work even in old versions of Perl. Noticed-by: Aaron Harnly
