Doing the dump via rpc can introduce all kins of strange
timing issiues. So instead we dump 5ms after the exit has
been started.

Because of fragmentation of memory it is not always possible
to allocate enough 320 MB segments on 32-bit so we only sent
smaller packets there.

This commit fixes an ETS test case that tests the decentralized memory
counter in tables of type ordered_set with the write_concurrency
option turned on. The test case assumed that the memory consumption of
the table would only grow monotonically when terms are
inserted. However, this was not the case when the emulator was
compiled in debug mode as random splits and joins of CA tree nodes
could happen. This commit fixes the test case by disabling random
splits and joins in the tested table.

1) Improved time calculations
When measuring the time something takes,
use monitonic time instead (of os:timestamp()).
2) Make sure we do not hang when the node start
hangs. We start new (slave) nodes via a starter process.
The point of that is that it can be killed when it
takes to long.

The cmsg header (decode) problems on darwin was because the
CMSG_FIRSTHDR macro is "faulty" on old versions (of darwin).
I *think* it should return a NULL-pointer if there are no
cmsg headers (but it does not). So, instead of punishing all
platforms with an explicit test
(msg_controllen >= sizeof(struct cmsghdr)) we only do this
on darwin.

When an evaluator skips (issue a exit or throw skip),
we must make sure all the other also terminates, before
the TC can end.
This was not done which cause the TC to fail when one
of the other evaluators (tester) terminated later.

When building the (activate next) select message, used terms
from different environments, which is not allowed.
This was during cancel of one request, we tries to activate
next, and then building the select message (with terms from
different environments). Arg! Details...

Why can't we all just get along? Casting to shut the compiler up.

When setting (otp) debug to true, some debug printouts
could become "laaarge". Removed the data from those
printout to avoid problems.

Did the free and assign new acceptor in the wrong order,
thereby causing an (acceptor) environment leak.

Building on windows broken again:
* The 'inline' keywork needs som work on windows.
* Function was outside of if-def.
* Missing prototypes resulted in default prototypes.
In this case, the actual problem was missing if-defs
for win32 (that made functions exist on windows
when they should not). Not sure why it compiled just
fine on win32 but not win64 though.

Forgot about using 'otp_build update_preloaded --no-commit'
when updating the preloaded and compiled with plain erlc...
Caused problems for dyalizer...

Make use of the new select functions; enif_select_[read|write],
for read and write select. These functions allows us to construct
the select message ourseves:
{'$socket', Socket, select, Ref}
This is in preparations for when we introduce the 'nowait'
(or something similar) value for the timeout argument (in accept,
read and write funcions).
It also solves (we hope) the term leakage problems (it was difficult
to free the environment when there was only one/socket).

Firstly, make sure socket (and own) options manipulations
are safe by adding a mutex that we take in the setopt and
getopt functions.
Secondly, change type prefix of various types from
'Socket' to 'ESock' (for instance; SocketDescriptor ->
ESockDescriptor).

To increase readability the close function has been slightly
restructured.
|
|
To increase readability the recvmsg result check has been slightly
restructured. In this case we made use of the error case function
(fail) of the recv result check.
|
|
To increase readability the recvfrom result check has been slightly
restructured. In this case we made use pf the error case function
(fail) of the recv result check.
|
|
To increase readability the recv result check has been slightly
restructured.
|
|
To increase readability the send result check has been slightly
restructured.
|
|
The messages sent from the nif code to an erlang process
has been changed to:
{'$socket', Socket :: socket(), Tag :: atom(), Info :: term()}
This is in preparation for (using) the new enif select API.

During a garbage collection, there could have been an overflow
in the old virtual heap.

Make sure that the instruction pointer is correct for a garbing
process in a crash dump.

Wait a little after to make sure that fun holding process to
complete its termination.

According to the comment, this rule was only needed when communication
with R7B nodes was supported.
|
|
With the new compiler in OTP 22, we have to use more options to
turn off optimizations.
This commit also skips the match_huge_int/1 test case in the
unoptimized clone of the bs_match_int module because it could
crash on memory-constrained computers.
