2017-10-30erl_process_dump: Don't assume that literals can be foundBjörn Gustavsson
Native code does not register its literals in the code header for the loaded code. Therefore, a literal created by native code can not be found by mark_literal(). Ignore literals that can't be found instead of crashing (the crasdump_viewer will report such literals as incomplete heap data, but will not crash).

2017-10-27Correct erlang:is_builtin/3 for apply/2 and yield/0Björn Gustavsson
erlang:is_builtin(erlang, M, F) returns false for apply/2 and yield/0. The documentation for erlang:is_builtin/3 says that it returns true for BIFs that are implemented in C. apply/2 and yield/0 are implemented in C (as BEAM instructions), and therefore the correct return value is true. Also see a similar argument that was made for apply/3 in the past: http://erlang.org/pipermail/erlang-bugs/2015-October/005101.html https://bugs.erlang.org/browse/ERL-500
2017-10-25sctp: change connect to only return connect errorsJonas Falkevik
gen_sctp:connect_init/4 could return error even though the connect are in progress. I.e. connect on socket returned "in progress". The error can come from packet_inet_output() which is checking the socket for errors. The issue here is that from erlang you don't think the connect is still ongoing. But you will receive a sctp_assoc_change message later on.

This fixes statistics_SUITE:msacc when dirty schedulers are used during the test.

2017-10-23erts: Fix so that bind correct schedulersLukas Larsson
When the cpu ids and scheduler ids don't match, the end schedulers could end up not being bound when they should be. example: > taskset -c 1-3 erl +S 4 +sbts > erlang:system_info(scheduler_bindings). {1,2,3,unbound} This fix makes it so that all cores are used to bind schedulers.

* bjorn/compiler/match-literals: Optimize instructions for comparing a register with a literal Optimize matching of literals for single-valued types
2017-10-21Optimize instructions for comparing a register with a literalBjörn Gustavsson
We can avoid calling eq() from the is_eq_exact_literal/3 and is_ne_exact_literal/3 instructions if the source operand is an immediate (since a literal is either a boxed or a list, never an immediate).

2017-10-18Dump literals separately to avoid incomplete heap dataBjörn Gustavsson
When a literal was used from several processes, the literal would be dumped in only one of the processes. The other processes that referenced the literals would have incomplete heap data.
2017-10-18Implement dumping of maps in crash dumpsBjörn Gustavsson
Maps would be dumped as the atom 'undefined', which is not very informative.
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.

The Linux real-time signal is better used on Linux for suspending schedulers during shutdown as it doesn't collide with SIGUSR2 usage of other applications.

2017-10-11Don't allow null chars in various stringsRickard Green
Various places that now reject null chars inside strings - Primitive file operations reject it in filenames. - Primitive environment variable operations reject it in names and values. - os:cmd() reject it in its input. Also '=' characters are rejected by primitive environment variable operations in environment variable names. Documentation has been updated to document null characters in these types of data as invalid. Currently these operations accept null chars at the end of strings, but that will change in the future.
