Dear all,
I've found that ssh_cli.erl does not scan the input received from the
remote for occurrences of <CTRL>+C to signal the user's interrupt
requests to the group_leader of the CLI session. The patch attached to
this e-mail fixes the issue.
Kind regards,

Subject: [PATCH] [SSH-CLI] properly handle <CTRL>+C as shell interrupt
In ssh_cli.erl, check for the presence of <CTRL>+C in data received from
the remote. If detected, use the established mechanism (send an
'interrupt' exit signal to the group_leader) to signal an interrupt to
the shell.

The test cases nc_SUITE:decompress_roundtrip and
nc_SUITE:compress_roundtrip fails on some machines with
OutOfMemoryException. This commit sets the max heap size for the jvm
to 256M in nc_SUITE in order to get around this.

Running some valgrind memory checking showed the error below:
==18040== Thread 6:
==18040== Source and destination overlap in memcpy(0xf3f3f04, 0xf3f3f08, 52)

This occurred on Linux using R15B01 while the shell was emitting a prompt,
but the same problem is still present in R16B.
Change the memcpy on line 845 of ttsl_drv.c to memmove as valgrind
suggests. After the change, verify with valgrind that the error no longer
occurs.

In some circumstances, as when inlining code, when some optimization
passes are disabled or with hand-written but semantically correct Core
Erlang or BEAM assembly, a fresh reference may be live in more than one
register:
...
{allocate_zero,2,2}.
...
{call_ext,0,{extfunc,erlang,make_ref,0}}. % Ref in [x0]
...
{move,{x,0},{y,0}}. % Ref in [x0,y0]
{move,{y,1},{x,0}}. % Ref in [y0]
...
{move,{y,0},{x,0}}. % Ref in [x0,y0]
{move,{x,0},{y,1}}. % Ref in [x0,y0,y1]
{label,5}.
{loop_rec,{f,6},{x,0}}. % Ref in [y0,y1]
...
{loop_rec_end,{f,5}}.
{label,6}.
{wait,{f,5}}.
...
Pass beam_receive expects a single live register for the ref when it
encounters the loop_rec instruction and crashes with the following
reason:
$ erlc t.S
...
crash reason: {{case_clause,
{'EXIT',
{{case_clause,[{y,1},{y,0}]},
[{beam_receive,opt_recv,5,
[{file,"beam_receive.erl"},{line,154}]},
...]}}},
...}
This commit teaches beam_receive how to use a set of registers instead
of a single one when tracking fresh references, thus avoiding the crash.

* siri/cuddle-with-tests:
[common_test] Adjusted timers in ct_repeat_testrun_SUITE
[common_test] Extend timer in cover_SUITE for slow test host
[sasl] Remove compiler warning in release_handler_SUITE
[common_test] Kill slave nodes after test cases in cover_SUITE
[reltool] Remove erlang:port_close/1 for node port
|
|
This is to allow slower test hosts.
|
|
|
|
|
|
The test case cover_SUITE:slave_start_slave often fails on a test host
(windows) due to a hanging node from an earlier test run. In the first
test, the slave fails to start (boot_timeout?) and is never connected
to the test node. The attempt at cleaning up used nodes() to find
which slaves to kill - so in the case where the slave was never
connected it was never killed. This is no changed so each slave is
explicitly killed by name - no matter if it is pingable or not.
|
|
Test nodes are started with erlang:open_port/2, using the -detached
option to erl. -detached causes the port returned from open_port/2 to
be closed automatically. Some test cases failed occasionally with a
badarg when attempting to close the port with erlang:port_close/1. To
avoid this the call to port_close/1 is now removed.

* ak/fix-cpu-overhead-of-timer-server/OTP-11053:
fix excessive CPU consumption of timer_server
|
|
I've found stdlib's timer to burn CPU without good reason. Here's what
happens.
The problem is that it sleeps in milliseconds but computes time in
microseconds. And there is bug in code to compute milliseconds to
sleep. It computes microseconds difference between now and nearest
timer event and then does _truncating_ division by 1000. So on average
it sleeps 500 microseconds _less than needed_. On wakeup its checks do
I have timer tick that already occurred? No. Ok how much I need to
sleep ? It does that bad computation again and gets 0
milliseconds. So next gen_server timeout happens right away only to
find we're still before closest timer tick and to decide to sleep 0
milliseconds again. And again and again.
This commit changes division to pick ceiling of ratio rather than
floor. So that we always sleep not less then difference between now
and closest event time.
