2019-05-02erts: Fix so that non-oneshot pollset on OpenBSD worksLukas Larsson
The poll code for kevent on OpenBSD and NetBSD had not been fixed to work properly when disabling events in the scheduler poll-set. Because they use ONESHOT the delete operation was built into the trigger and thus a lot of code was not needed when doing oneshot, however it is needed when doing non-oneshot.

2019-05-02erts: Remove dead cpu info code in erlexecLukas Larsson
This was previously used when erlexec needed to decide whether to run the smp or non-smp emulator.

* lukas/erts/distr-frag-fixes: Update run-dialyzer script to be more generic and aggressive erts: Fix memory leak for down/exit message
2019-05-02erts: Fix PGO configure test for gccLukas Larsson
The problem was that some on some platforms -fprofile-generate does not imply -lgcov which means that it will not link.

2019-04-30[net] Improvements (ahum) when --disable-esockMicael Karlberg
The net module uses socket, but when the system has been built with --disable-esock, there is no socket...

2019-04-30[socket|net] Fixed beamsMicael Karlberg
Forgot about using 'otp_build update_preloaded --no-commit' when updating the preloaded and compiled with plain erlc... Caused problems for dyalizer... OTP-15658
2019-04-30[socket|net] Preloaded now built with latest compilerMicael Karlberg
OTP-15658
2019-04-30[socket|net] Final prepMicael Karlberg
The config options --[en|dis]able-esock now works as expected.
2019-04-30[socket] Preloaded (erts) app fileMicael Karlberg
The optional socket module is now not included in the app file if esock is not enabled. OTP-15658
2019-04-30[socket] Preliminary - make socket configurableMicael Karlberg
Preliminary work to make socket configurable (enable and disable). OTP-15658

2019-04-30erts: Fix memory leak for down/exit messageLukas Larsson
When a fragmented down/exit is sent to a non-existing process the message would just be dropped without being deallocated.
2019-04-29erts: Fix bug in timer wheel at cancel during bump yieldSverker Eriksson
Symptom: Failed debug assert in find_next_timeout ERTS_TW_ASSERT(tiw->yield_slot == ERTS_TW_SLOT_INACTIVE); Problem: If remove_timer() was called in between yielding erts_bump_timers() tiw->true_next_timeout_time could be set to 0 leading to find_next_timeout() being called before all bumping is done. Solution: Don't clear tiw->true_next_timeout_time in remove_timer() if tiw->yield_slot is active. Does not seem this bug could cause other more harmful symptoms, but not sure.

* rickard/dist-system-limit/OTP-15708: Fail when we cannot encode term in binary
2019-04-18Make persistent_term:put/2 and persistent_term:erase/1 yieldKjell Winblad
Prior to this commit, the functions put/2 and erase/1 in the persistent_term module did not yield even if the persistent term table was large (the persistent term table is copied every time put/2 or erase/1 is called). Furthermore, a call to put/2 or erase/1 did only consume a single reduction. This commit fixes these problems.

2019-04-18erts: Yield correctly when iterating over distr exit messagesLukas Larsson
Before this fix the process would continue to process more distributed down or exit messages until it ran out of reductions instead of being suspended immediately.

2019-04-18erts: Make dump_SUITE:free_dump not dump via rpcLukas Larsson
Doing the dump via rpc can introduce all kins of strange timing issiues. So instead we dump 5ms after the exit has been started.
2019-04-18erts: Add extra debugging to dist frag testcasesLukas Larsson
2019-04-18erts: Run smaller dist frag test to 32 bit machinesLukas Larsson
Because of fragmentation of memory it is not always possible to allocate enough 320 MB segments on 32-bit so we only sent smaller packets there.
2019-04-18Fix broken ETS test caseKjell Winblad
This commit fixes an ETS test case that tests the decentralized memory counter in tables of type ordered_set with the write_concurrency option turned on. The test case assumed that the memory consumption of the table would only grow monotonically when terms are inserted. However, this was not the case when the emulator was compiled in debug mode as random splits and joins of CA tree nodes could happen. This commit fixes the test case by disabling random splits and joins in the tested table.
2019-04-17[socket|test] Timing and node startsMicael Karlberg
1) Improved time calculations When measuring the time something takes, use monitonic time instead (of os:timestamp()). 2) Make sure we do not hang when the node start hangs. We start new (slave) nodes via a starter process. The point of that is that it can be killed when it takes to long.
