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.

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

Without this fix asserts would trigger in debug build
but nothing else would break.

* john/erts/remove-destructive-bs_get_binary2/ERL-901:
erts: Remove unsafe bs_get_binary2 optimization from loader
|
|
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.

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.
|
|
|
|
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.
|
|
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.
|
|
|
|
|
|
Setting the hole marker in debug on the entire heap is very slow
so instead we do it in erts_produce_heap.

This needs to be done in order for automatic fd leak checking
to work properly.
|

|
|
|
|
|
|
When the calling process is trapping exits a stray message
will end up in the mailbox which is problematic. This change
uses a monitor instead.
