to disregard consumed virtual reductions
which are not aggregated into p->reds
and if included may cause reduction count go backwards.
|

No need to pre-allocate a buffer before name length calculation.

* kjell/emulator/persistent_term_yield/OTP-15615:
Make persistent_term:put/2 and persistent_term:erase/1 yield
|
|
* rickard/dist-system-limit/OTP-15708:
Fail when we cannot encode term in binary
|
|
Prior to this commit, the functions put/2 and erase/1 in the
persistent_term module did not yield even if the persistent term table
was large (the persistent term table is copied every time put/2 or
erase/1 is called). Furthermore, a call to put/2 or erase/1 did only
consume a single reduction. This commit fixes these problems.

erts: Fix cerl -rr to use correct etp file
erts: Fix etp-process-info to print exiting and free processes
tools: Adjust instrument abort tc to better trigger faults
erts: Fix cleanup of message factory undo
erts: Make dump_SUITE:free_dump not dump via rpc
erts: Add extra debugging to dist frag testcases
erts: Run smaller dist frag test to 32 bit machines

otp: make top Makefile app target respect TYPE variable
vxworks: Make vxworks configure use environment CFLAGS
erts: Make erts_free debug failure easier to diagnose
erts: Fix gcc warning in to_erl

Before this fix the process would continue to process
more distributed down or exit messages until it
ran out of reductions instead of being suspended
immediately.
|
|
|
|
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.

When building the (recv) select message, used terms
from different environments, which is not allowed.

When building the (accept) select message, used terms
from different environments, which is not allowed.

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.

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.

* bjorn/cuddle-with-tests:
crash dump: Fix printing of "OldBinVHeap unused"
crash dump: Include correct IP for a garbing process
fun_SUITE: Make refc/1 test more reliable
Remove redundant rule from Emakefile
Turn off more optimizations for no_opt modules
test_server_node: Bump compiler compatibility version to OTP 20
erts_test_utils: Bump compiler compatibility version to OTP 20

bs_construct_SUITE: Remove troublesome test huge_binary/1
bs_construct_SUITE: Remove incorrect purpose line
|
|
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.

|
Communication with OTP R16b has not been supported for a while.
|
|
The test case tests that the bs_append instruction tests for overflow.
Make that clear by renaming the test case.
While at it, also add a few explicit garbage_collection/0 calls to
make it more likeley to run successfully in tight memory situations.
|
|
This test case can fail for the wrong reason (swapping
followed by a timetrap timeout). It is unlikely to fail because
of a real bug.
