* sverker/erts/crash-dump-limit: erts: Add env variable ERL_CRASH_DUMP_BYTES erts: Add ErtsStrToSint64 erts: Refactor crash dumping with cbprintf erts: Add cbprintf for Callback Printing erts: Remove unused erl_crash_dump()
2016-11-22erts: Add env variable ERL_CRASH_DUMP_BYTESSverker Eriksson
to limit crash dump size
2016-11-17erts: Add ErtsStrToSint64Sverker Eriksson
for simplify string to 64-bit integer parsing.
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.

2016-10-27Merge branch 'sverker/purge-fix/OTP-13925' into maintSverker Eriksson
2016-10-26erts: Avoid delayed fun undef raceSverker Eriksson
Avoid suspending fun caller not just if purge is already done but also if purge of another module has started. Another purge of the same module again cannot happen as making current to old transition includes thread progress.

into maint * lukas/erts/tracing/fix_dead_tracer_check/ERL-274/OTP-13928: erts: Do tracer liveness check on current tracer

in Text part of error tuple, like {error, {load, "Library load-call unsuccessful (606)}}
2016-10-04erts: Do tracer liveness check on current tracerLukas Larsson
This fixes a fault introduced in 19.0 where an invalid tracer would block setting of a new tracer on a process.
2016-09-29Fix minor soft purge bugRickard Green
A process calling a fun from a module currently being soft-purged could race with failure of the soft purge. When this happened the call triggered loading of the module which erroneously would load new code for the module in the case no new generation was currently loaded.

2016-09-14Don't leak old code when loading a modules with an on_load functionBjörn Gustavsson
Normally, calling code:delete/1 before re-loading the code for a module is unnecessary but causes no problem. But there will be be problems if the new code has an on_load function. Code with an on_load function will always be loaded as old code to allowed it to be easily purged if the on_load function would fail. If the on_load function succeeds, the old and current code will be swapped. So in the scenario where code:delete/1 has been called explicitly, there is old code but no current code. Loading code with an on_load function will cause the reference to the old code to be overwritten. That will at best cause a memory leak, and at worst an emulator crash (especially if NIFs are involved). To avoid that situation, we will put the code with the on_load function in a special, third slot in Module. ERL-240

2016-09-05Fix erts_thr_progress_unmanaged_delay()Rickard Green
Thread progress leader update did not cache current unmanaged index when waiting for unmanaged threads. This caused erts_thr_progress_unmanaged_delay() to stop working until a new leader took over.

When running the signal handler, the errno has to be restored to its original value, otherwise code running in the same thread may misbehave.
