OTP-13251 * sverk/halt-INT_MIN: erts: Make erlang:halt() accept bignums as Status erts: Change erl_exit into erts_exit kernel: Remove calls to erl_exit

2016-02-24erts: Make erlang:halt() accept bignums as StatusSverker Eriksson
Just mask away the high bits to get a more tolerant erlang:halt that behaves the same on 32 and 64 bit architectures.
2016-02-24erts: Change erl_exit into erts_exitSverker Eriksson
This is mostly a pure refactoring. Except for the buggy cases when calling erlang:halt() with a positive integer in the range -(INT_MIN+2) to -INT_MIN that got confused with ERTS_ABORT_EXIT, ERTS_DUMP_EXIT and ERTS_INTR_EXIT. Outcome OLD erl_exit(n, ) NEW erts_exit(n, ) ------- ------------------- ------------------------------------------- exit(Status) n = -Status <= 0 n = Status >= 0 crashdump+abort n > 0, ignore n n = ERTS_ERROR_EXIT < 0 The outcome of the old ERTS_ABORT_EXIT, ERTS_INTR_EXIT and ERTS_DUMP_EXIT are the same as before (even though their values have changed).

This commit implements erts_internal:system_check(schedulers) with the intent of a basic responsiveness test check of the schedulers.

2016-01-28erts: Fix bug concerning line information for hipe modulesSverker Eriksson
Line table was left uninitialized for hipe (stub) modules causing process_info(OtherPid, current_location) to crash.

* rickard/test-fix: Fix HL timer hard debug implementation Fix stack alignment problem in ethread test on arm Skip time_SUITE:timestamp on timewarp test
2016-01-21Introduce time management in native APIsRickard Green
2016-01-20Introduce time warp safe replacement for safe_fixed optionRickard Green
The new time warp safe option is safe_fixed_monotonic_time which gives erlang:monotonic_time(). The safe_fixed option was also slightly changed. It now gives erlang:timestamp() instead of erlang:now(). This has however not been documented, so it is considered a compatible change. The above effects both ets, and dets. This commit also include the bugfix OTP-13239 for dets:info(Tab, safe_fixed). The timestamp in the result returned by dets:info(Tab, safe_fixed) was unintentionally broken as a result of the time API rewrites in OTP 18.0.
2016-01-20Introduce time warp safe trace timestamp formatsRickard Green
New timestamp options for trace, sequential trace, and system profile: - monotonic_timestamp - strict_monotonic_timestamp

2015-12-21Do not allow aux work on dirty schedulersSteve Vinoski
The nature of aux work is such that dirty schedulers should not attempt to perform it. Modify the code to ensure that dirty schedulers avoid aux work. Also fix an incorrect assumption about the size of a Uint in the ErtsDirtySchedId type.

2015-12-04Remove ERTS_PRINT_INVALID from erts_print()Rickard Green
ERTS_PRINT_INVALID prevented file descriptor 0 to be used which could cause an empty crash dump.
2015-12-03erts: Fix bug in heap_factory_undo for FACTORY_HEAP_FRAGS modeSverker Eriksson
Make sure a heap fragment is not deallocated before all off_heap terms have been cleared. The fix assumes/asserts that the off_heap-lists of all additional heap fragments are empty. I think this bug has been harmless as hashmap nodes, which is only ones (?) that can cause a factory to produce more heap, are not linked in off_heap-list.
2015-12-02beam: Fix overflow bug in i_bs_add_jIdMagnus Lång
The test whether the result would fit in a smallnum could overflow into a negative number that would fit a smallnum. A test that reproduces the issue was added to bs_construct_SUITE.

Decoding a term with a large (HAMT) map in an small (FLAT) map could cause a critical error if the external format was not produced by beam.
