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.

2014-10-26Fix "-smp disable" for emulator with dirty schedulersSteve Vinoski
Running "erl -smp disable" on an emulator built with dirty scheduler support caused problems such as segmentation violations and emulator status line outputs containing garbage. For example: $ erl -smp disable Segmentation fault (core dumped) and: $ erl -smp disable Erlang/OTP 17 [DEVELOPMENT] [erts-6.2] [source] [64-bit] [ds:10:4297895689:4299948152] [async-threads:280] This problem also caused the emulator smoke_test_SUITE to hit these same problems if run in an emulator started with the "-smp disable" option. Fix this segmentation violation by ensuring that dirty scheduler information is printed in the status line only when the emulator is compiled with ERTS_SMP enabled. With this fix in place, the smoke_test_SUITE now passes when the "-smp disable" option is used, and the emulator status line prints correctly for both "-smp enable" and "-smp disable": $ erl -smp enable Erlang/OTP 17 [DEVELOPMENT] [erts-6.2] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:10] [kernel-poll:false] and: $ erl -smp disable Erlang/OTP 17 [DEVELOPMENT] [erts-6.2] [source] [64-bit] [async-threads:10] [kernel-poll:false]

2014-10-20erts: Fix bug causing mbc to be deleted from cpool before it was insertedSverker Eriksson
Set IN_POOL flag _after_ mbc has been actually inserted. Earlier it did not matter if IN_POOL was set early as it was not possible to find a carrier before is was fully inserted. Now when searching pooled_list and traitor_list we must make sure a found carrier has been fully inserted into cpool before removing it.
2014-10-16erts: Make writing to non-tty fds non-blockingLukas Larsson
If the fd_driver is given non-tty fds it will now use an async thread instead of doing a blocking write. An example of a non-tty fd is the fd used by stderr, but could be anything handed down to the driver.

2014-10-06erts: Fix bug causing mbc removed from cpool to be used at pool entranceSverker Eriksson
Clear both IN_POOL and BUSY flags when empty carrier is removed is removed from pool to be destroyed. Earlier it was enough to leave BUSY flag set but now with pooled_list we must clear IN_POOL to avoid using it as cpool_entrance in cpool_fetch().

2014-10-03erts: Fix bug when delayed deallocated carrier is reused by cpool_fetchSverker Eriksson
The delayed dealloc queue destroyes one word but cpool_fetch() is expected to return healthy carriers. So we restore that overwritten word with a little bit of hackish code.

In the ERL_NIF_INIT macro, add a missing static initializer for the new options field which was added to the ErlNifEntry struct for 17.3. This fix prevents compile-time errors in NIFs when the compiler is instructed to treat missing field initializers as errors.
2014-09-30erts: Fix race between port_set_data, port_get_data and port terminationSverker Eriksson
Always update prt->data with atomic xchg-op. Check for NULL data to detect racing port terminator. Use NULL, as THE_NON_VALUE can be a valid pointer on debug VM.

enif_schedule_nif() put LAST of the unconditional functions to keep the order which is vital for ABI compatibility on Windows. The conditional dirty scheduler stuff moved down at the end of the list to keep them out of the way. We don't want them mess things up then they become unconditional some day.
