2019-04-01efile_SUITE: Fix proc_zero_sized_files on systems with empty /procJohn Högberg
This test would fail on some versions of FreeBSD because /proc was present but empty. This commit makes the test fail if and only if a known zero-sized file is found and turns out to be empty empty.

2019-03-29Fix out of memory bug in the implementation of mapsKjell Winblad
This commit fixes a bug that could cause a crash or memory usage to grow until the machine ran out of memory when adding a key-value pair to a map. This could happen when inserting a new key-value pair with a key K1 containing a binary B1 into a map M having a key K2 with a binary B2 if the following conditions were met: * size(B1) >= 4294967296 * size(B2) >= 4294967296 * size(M) >= 32 * (size(B1) rem 4294967296) == (size(B2) rem 4294967296) * the first (size(B1) rem 4294967296) bytes are the same both in B1 and B2 * substituting B1 in K1 with B2 would result in a term with the same value as K2 The root cause of the bug is that the map implementation only hashed the first (X modulo 4294967296) bytes of binaries so that different binaries could get hashed to the same hash value independently of the hash seed.

There's no way to create the file in question, so we may as well skip the test.

returning incorrect result as * current process might not be RUNNING in which case REDS_IN is actually used as def_arg_reg[5] * FCALLS might not have been swapped out * the SAVED_CALLS case was wrong and returned number of reds left
2019-03-28erts: Use ptr_val for pointer in gc msg copySverker Eriksson
Cherry-pick: 3d7d66b84b69f3eb42e8bcd8dc510b6676e31cac Without this fix asserts would trigger in debug build but nothing else would break.

2019-03-27erts: Remove unsafe bs_get_binary2 optimization from loaderJohn Högberg
A load-time optimization assumed that match contexts had no further uses when a bs_get_binary2 overwrote the match context's register, and figured it would be safe to reuse the match context's memory for the resulting binary. This is no longer safe as of OTP 22, as a match context may be reused after being passed to another function.

2019-03-27erts: Handle all signal types when clearing seq_trace tokenJohn Högberg
We walk through all signal queues in the system when clearing seq_trace, so we must be prepared to encounter all kinds of signals.

2019-03-25erts: Include external msg in need of GCLukas Larsson
When many external messages suddenly appear in the mailbox the young gen size is adjusted accordingly but it was immediately shrunk as the data was not counted towards the shrink size. This commit includes the ext dist size in the shrink calculation which means that the decode of the external messages will not trigger as many GCs which means much better performance.
2019-03-25erts: Include dist header in return from dist_ctrl_get_dataLukas Larsson
2019-03-25erts: Fix so that exit/down terms stay aliveLukas Larsson
When the GC is run or the link/monitor node is deleted, the terms associated with it will also be deallocated so we have to make sure that we don't do any GCs and that all link/monitor nodes are copied onto the heap before the node is deallocated.
2019-03-25erts: Pending signals can be for free processesLukas Larsson
Since we no schedule free processes multiple times, pending signals can be from free as well as current processes.

When interacting with jinterface and erl_interface the old dist messages are used and they incorrectly used the external data.

2019-03-25erts: erts_factory_proc_init should not set hole markerLukas Larsson
Setting the hole marker in debug on the entire heap is very slow so instead we do it in erts_produce_heap.
