Since Erlang/OTP 21 "//" can be opened for writing on Windows, but
writing to the file causes file_io_server to crash.

ssl: Correct test case
ssl: Remove test cases from ssl_basic_SUITE
ssl: Remove basic test group from ssl_to_openssl_SUITE

Optimization to concatenate small user data packages recived
closely after each other has invalidated assumptions in the test case.
|
|
The test are moved to ssl_cipher_suite_SUITE
|
|
This group has started to fail as our default has diverged from OpenSSL
defaults and we are not really interested in testing OpenSSL defaults.

* john/erts/seq_trace-sigq-clearing/OTP-15704:
erts: Handle all signal types when clearing seq_trace token
|
|
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.

Fix unsafe optimization made by the loader
|
|
We walk through all signal queues in the system when clearing
seq_trace, so we must be prepared to encounter all kinds of
signals.

Fix the unsafe load-time optimization introduced in 07bdbb3a1edc.

This reverts commit 3a8047fcd347a30b0340839437cf367e5b9be339.
|
|
Validation could fail when a function that never returned was used
in a try block (see attached test case). It's possible to solve
this without disabling the optimization as the generated code is
sound, but I'm not comfortable making such a large change this
close to the OTP 22 release.

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.

FreeBSD recently switched from using ld.lld instead of ld.bfd
for linking, which means that ld does not work as it did. So
we use cc to link all dynamic libraries. We also assume that
dragonfly and netbsd will follow.

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