2018-02-20erts,observer: Add dirty schedulers to crash dumpSverker Eriksson
2018-02-20erts: Add binary vheap sizes to crash dumpSverker Eriksson
2017-11-21Use base64 encoding in crash dumpsBjörn Gustavsson
This will reduce the size of crash dumps, especially if there are large binaries.
2017-10-18Bump version of crash dumps to 0.4Björn Gustavsson
2017-10-18Buffer writing of crash dumpsBjörn Gustavsson
Writing of crash dumps were done using unbuffered IO. This is slow since many small writes are done. Use a FILE* with an allocated buffer to obtain buffered IO. I wrote a small test program that created 50000 binaries of 200 bytes each and then created a crash dump. The crash dumping was an order of magnitude faster with buffered IO than without.

2017-04-18Timer wheel divided into a "soon wheel" and a "later wheel"Rickard Green
The old single wheel implementation handled about 65 seconds. The new dual wheel implementation handles more than 37 hours. The dual wheels have also been shrunk compared to the single wheel, so the total memory consumption for timer wheels have been cut in half.

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()

2016-10-12erts: Refactor out func_info into structLukas Larsson
This commit adds two new structs to be used to represent erlang code in erts. ErtsCodeInfo is used to describe the i_func_info header that is part of all Export entries and the prelude of each function. This replaces all the BeamInstr * that were previously used to point to these locations. After this change the code should never use BeamInstr * with offsets to figure out different parts of the func_info header. ErtsCodeMFA is a struct that is used to descripe a MFA in code. It is used within ErtsCodeInfo and also in Process->current. All function that previously took Eterm * or BeamInstr * to identify a MFA now use the ErtsCodeMFA or ErtsCodeInfo where appropriate. The code has been tested to work when adding a new field to the ErtsCodeInfo struct, but some updates are needed in ops.tab to make it work.

* dotsimon/gc-info-crashdump/PR-1026/OTP-13541: Print heap pointers for garbing processes during crashdump
2016-04-25Print heap pointers for garbing processes during crashdumpSimon Cornish
In an SMP emulator, print_garb_info doesn't do anything because the heap pointers could be invalid. However, when crashdumping there are no schedulers running so it's ok to print this additional information which could be useful when examining a core file.

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).

2015-11-12Fragmented young heap generation and off_heap_message_queue optionRickard Green
* The youngest generation of the heap can now consist of multiple blocks. Heap fragments and message fragments are added to the youngest generation when needed without triggering a GC. After a GC the youngest generation is contained in one single block. * The off_heap_message_queue process flag has been added. When enabled all message data in the queue is kept off heap. When a message is selected from the queue, the message fragment (or heap fragment) containing the actual message is attached to the youngest generation. Messages stored off heap is not part of GC.
