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
|

Cherry-pick: 3d7d66b84b69f3eb42e8bcd8dc510b6676e31cac
Without this fix asserts would trigger in debug build
but nothing else would break.

Jumping around in a compressed file is nowhere near as cheap as
for uncompressed files, as it requires reading and decompressing
up until the desired position. Using read_ahead will improve
performance slightly.

|
An internal buffer size was too small, causing a considerable
performance degradation compared to OTP 20.

This is a simplistic distribution protocol module for
encrypted distribution using a shared secret and only
the crypto module, and AEAD ciphers.
It is intended to be a benchmark reference for how fast
encrypted distribution may get.
How secure it would be and also how useful, for actual production use,
remains to be investigated.

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.

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.
