2017-04-12erts: Introduce struct binary_internalsSverker Eriksson
to replace macro ERTS_INTERNAL_BINARY_FIELDS as header in Binary and friends.
2017-04-11erts: Introduce erts_bin_releaseSverker Eriksson
2017-03-22Use ETS table id references on select_replaceGuilherme Andrade
2017-03-22Disable ets:select_replace/2 for bagsGuilherme Andrade
The existing implementation presented both semantic inconsistencies and performance issues.
2017-03-22ETS: Allow for matchspec-based replacementGuilherme Andrade
2017-03-22erts: Improve reduction count during table cleanupSverker Eriksson
2017-03-22erts: Cleanup table status bitsSverker Eriksson
2017-03-22erts: Remove now redundant 'id' from DbTableCommonRickard Green
'the_name' keeps name of all tables. 'type' & DB_NAMED_TABLE mark tables as named. table ref id is built from magic bin when needed.
2017-03-22erts: Remove meta_main_tabSverker Eriksson
\o/ O / \ Also removed the body for CHECK_TABLES enabled by HARDDEBUG. Removed quite useless check for hash, but kept dead check code for tree.
2017-03-22erts: Pass tid argument down to trapping functionsSverker Eriksson
to get rid of meta table lookup by integer (tb->common.id)
2017-03-22erts: Print table id as ref in crashdump and break menuSverker Eriksson
2017-03-22erts: Replace meta_pid_to{_fixed}_tab with linked listsSverker Eriksson
from process psd through all owned/fixed tables. As meta_pid_to{_fixed}_tab maps to slot in meta_main_tab which is planned for destruction. In this commit we no longer seize table lock while freeing the table (free_table_cont) as it's not needed and makes the code a bit simpler. Any concurrent operation on the table will only access lock, owner and status and then bail out.

2017-02-06Atomic reference count of binaries also in non-SMPRickard Green
NIF resources was not handled in a thread-safe manner in the runtime system without SMP support. As a consequence of this fix, the following driver functions are now thread-safe also in the runtime system without SMP support: - driver_free_binary() - driver_realloc_binary() - driver_binary_get_refc() - driver_binary_inc_refc() - driver_binary_dec_refc()

2016-11-17erts: Refactor crash dumping with cbprintfSverker Eriksson
Instead of passing around a file descriptor use a function pointer to facilitate more advanced backend write logic such as size limitation or compression.

- Termination of a process... - Modify trace flags of process... - Process info on process... - Register/unregister of name on process... - Set group leader on process... ... while it is executing a dirty NIF.

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).

* maint: Introduce time management in native APIs Introduce time warp safe replacement for safe_fixed option Introduce time warp safe trace timestamp formats Conflicts: erts/emulator/beam/erl_bif_trace.c erts/emulator/beam/erl_driver.h erts/emulator/beam/erl_nif.h erts/emulator/beam/erl_trace.c erts/preloaded/ebin/erlang.beam
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.
2015-11-18Refactor sharing preserved copy flagsBjörn-Egil Dahlberg
The TMPBUF option is no longer needed due to is_literal test and NONE was only used for initial debugging. So we remove the entire option.

2014-04-29Fix race between ETS table deletion and unfixationSverker Eriksson
Symptom: VM crash running mnesia_SUITE Scenario: Process A terminates while still having fixed table T and process B "at the same time" deletes table T with ets:delete/1 or by terminating. Problem: A table scheduled for deallocation do only have a valid 'common' part. The unfix-table-at-process-exit code tried to read the hash-specific part of such a table. Solution: Must back off if DB_DELETE flag is set. Since: R16B

2013-09-30erts: Refactor the ASSERT macroSverker Eriksson
Introduce unconditional ERTS_ASSERT and use that for both ASSERT and ASSERT_EXPR.
2013-09-24add system_info(ets_limit)Steve Vinoski
Add system_info(ets_limit) to provide a way to retrieve the runtime's maximum number of ETS tables. Add tests and documentation for it too. Also repair the alphabetical order of system_info/1 argument descriptions in the documentation and in the erlang.erl clauses. Add new preloaded erlang.erl due to that change. Also ensure all system_info/1 clauses are represented in the erlang.xml source documentation -- a couple had been inadvertently dropped in previous commits when other clauses were added.
