2014-12-19Merge branch 'lukas/erts/crashdump_improvements/OTP-12377'Lukas Larsson
* lukas/erts/crashdump_improvements/OTP-12377: erts: Make main thread safe from pipe closed event erts: Improve crash dumps erts: Rename sys_sigset to sys_signal erts: Introduce thread suspend functions erts: Remove usage of QUANTIFY signal erts: Add support for thread names ets: Increase data available in crash dumps and ets:info erts: Start compilation of beam_emu earlier
2014-12-19erts: Improve crash dumpsLukas Larsson
This commit improves crash dumps in several ways: * Suspends schedulers to get a current snapshot * Dumps information about scheduler * Dumps stack trace of current running process (including Garbing processes)
2014-12-19erts: Introduce thread suspend functionsLukas Larsson
These functions allow any thread to suspend any other thread immediately and then resume all threads. This is useful when doing a crash dump in order to get a more accurate picture of what state the system is in.

2014-12-10Introduce a 64-bit atomic ops APIRickard Green
The 64-bit atomic ops API is implemented by * native word size atomic ops on 64-bit architectures, and * native double word size atomic ops on 32-bit architectures when available. When native double word size atomic is not available, the fallback using modification counters is used.

2014-11-04Fix gc-related problem with dirty NIFsSteve Vinoski
Ensure that the return value from a dirty NIF call is made part of the GC rootset. Add a new regression test to nif_SUITE. Thanks to Daniel Goertzen for reporting the error and providing a test case, and to Sverker Eriksson for making test case reproducible and finding the fix.

2014-11-02Expose NIF versionPeter Lemenkov
This patch allows checking for NIF API version in a way similar to driver version. E.g. by calling erlang:system_info(nif_version). Signed-off-by: Peter Lemenkov <[email protected]>
2014-10-29erts: Fix bug in beam_rangesSverker Eriksson
Symptom: VM on OSX (darwin11.4.2) with +Meamin running sasl tests, crashing when init:reboot() does erlang:purge_module(installer). Problem: Off-by-one bug in beam_ranges:find_range, returning the wrong range if the 'end' of one module is the 'start' of the next. This is only possible if using sys_alloc (+Meamin) as our own allocators always put block headers between allocated payload data.

2014-10-28Use isfinite() instead of finite() when availableAnthony Ramine
OS X Mavericks builds result in a number of warnings about finite() being deprecated, like these: beam/erl_arith.c:451:7: warning: 'finite' is deprecated: first deprecated in OS X 10.9 [-Wdeprecated-declarations] ERTS_FP_ERROR(p, f1.fd, goto badarith); ^ sys/unix/erl_unix_sys.h:319:33: note: expanded from macro 'ERTS_FP_ERROR' ^ sys/unix/erl_unix_sys.h:244:51: note: expanded from macro '__ERTS_FP_ERROR' ^ /usr/include/math.h:718:12: note: 'finite' has been explicitly marked deprecated here extern int finite(double) __OSX_AVAILABLE_BUT_DEPRECATED(__MAC_10_0, __MAC_10_9, __IPHONE_NA, __IPHONE_NA); Add checks to use isfinite() instead of finite() where available. Verified on OS X Mavericks 10.9.5 and Ubuntu 12.04.
