* nox/silent-rules-fixes/OTP-11351:
Fix two small silent rules omissions
|
|

config.h defines HAVE_SYSLOG_H whereas the sources are looking for
NO_SYSLOG to be undefined. As the logic of "if feature is available"
makes more sense than "if feature is not unavailable", I opted for the
config.h define.

* sverk/valgrind-single-core:
erts: Speed up valgrind with asynch threads
|
|
|
|
For applications where measurements show enhanced performance from the use
of a non-default number of emulator scheduler threads, having to accurately
set the right number of scheduler threads across multiple hosts each with
different numbers of logical processors is difficult because the erl +S
option requires absolute numbers of scheduler threads and scheduler threads
online to be specified.
To address this issue, add a +SP option to erl, similar to the existing +S
option but allowing the number of scheduler threads and scheduler threads
online to be set as percentages of logical processors configured and
logical processors available, respectively. For example, "+SP 50:25" sets
the number of scheduler threads to 50% of the logical processors
configured, and the number of scheduler threads online to 25% of the
logical processors available. The +SP option also interacts with any
settings specified with the +S option, such that the combination of options
"+S 4:4 +SP 50:50" (in either order) results in 2 scheduler threads and 2
scheduler threads online.
Add documentation for the +SP option.
Add tests for the +SP option to scheduler_SUITE.
Add tests and documentation for two existing features of the +S option: +S
0:0 resets the scheduler thread count and scheduler threads online count to
their defaults, and specifying negative numbers for +S results in those
values being subtracted from the default values for the host.

by only letting it run on one core. Valgrind only let one thread
at a time execute anyway.

* weisslj/run-erl-redirect-dev-null/OTP-11215:
run_erl: Redirect standard streams to /dev/null

|
* sze/to_erl/OTP-11206:
Fix changing terminal parameters in to_erl
|
|
One of our devices does not like 'to_erl' to be run over a serial port.
When to_erl is started, we see "Attaching to /tm<0xFF>" being printed
and the device then refuses to accept any input. Occasionally, we have
seen a linux kernel error message "serial8250: too much work for irq16"
simultaneously. After some debugging we found out that cause is a call
to tcsetattr() by to_erl, immediately preceeded by some printf().
The UART in our device doesn't like hardware parameters to be changed
while output is concurrently active. In fact, the GNU libc manual also
mentions that it might be dangerous to change UART hardware parameters
when a transmission is ongoing.
The patch attached to this e-mail changes the behaviour of to_erl to use
TCSADRAIN instead of TCSANOW when changing terminal parameters. This
makes the serial driver wait for the output queues to be empty before
applying the terminal parameter change.

Like in epmd and erlexec. Otherwise "run_erl" fails on some platforms
when called with the "-daemon" option, printing this error:
"Cannot dup"

+sfwi Interval
Set scheduler forced wakeup interval. All run queues will be scanned
each Interval milliseconds. While there are sleeping schedulers in
the system, one scheduler will be woken for each non-empty run queue
found. An Interval of zero disables this feature, which also is the
default.
This feature has been introduced as a temporary workaround for lengthy
executing native code, and native code that do not bump reductions
properly in OTP. When these bugs have be fixed the +sfwi flag will
be removed.

This is the base for implementing configurable

characters to view as actually printable in the shell and
by io_lib:format.

The following are deliberately left, as I have only a list of compiler
warnings and no system to test on:

With silent rules, the output of make is less verbose and compilation
warnings are easier to spot. Silent rules are disabled by default and
can be disabled or enabled at will by make V=0 and make V=1.

According to the documentation, if the second or third line in a
script starts with %%!, then escript will use the rest of the line
as emulator options. However, previously this was only the case
if the first line started with #!. This change removes that check,
and unconditionally uses the %%! line if present.
