Update preloaded
add system_info(ets_limit)
Conflicts:
erts/preloaded/ebin/erlang.beam
|
|
Add system_info(ets_limit) to provide a way to retrieve the runtime's
maximum number of ETS tables. Add tests and documentation for it too.
Also repair the alphabetical order of system_info/1 argument descriptions
in the documentation and in the erlang.erl clauses. Add new preloaded
erlang.erl due to that change. Also ensure all system_info/1 clauses are
represented in the erlang.xml source documentation -- a couple had been
inadvertently dropped in previous commits when other clauses were added.

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.

Clear the "enabled" flag for scheduling statistics when disable is
specified.

When integer_to_binary/2 receives 0 or a negative number as an argument
with a base that is different from 10, it will return incorrect values
(<<>> in the case of 0) or it will crash (with negative numbers). This
commit fixes these problems and adds tests to cover these cases.

* maint:
add erl option to set schedulers by percentages
|
|
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.

begin_port_cleanup can be called from a non-scheduler thread, this
means that there is no esdp available and thus erts_schedule_thr_prgr_later_op
segfaults.

The actual port id is used to create a key from the
pointer value which is the ErlDrvPort. To do this
a new driver api function driver_async_port_key is
added and the driver API minor version is updated.
The documentation is updated and the faulty description of
how to spread ports over async threads is updated to
use the new API.
Testcase also added.

The bug manifests so that initialization of an automatic variable
happens after a pointer to the variable is dereferenced, causing
build_exec_return to take the wrong branch by default.
The bug is verified to happen even outside the VM and
is reported to FreeBSD as trouble ID gnu/181328.
The workaround is a slight code rewrite which is optimized differently.
Also removed two warnings about dereferencing type-punned
pointers, which did not affect the bug.
|
|
This is needed as some gcc versions seems to optimize this undefined
behaviour in a way which breaks this code.

Just some clarifying comments to future progremmers to keep the relation
between error returns from the two functions.

Added to re:run and sets the corresponding fields in 'extra' struct
for the PCRE match engine. The result can be viewed by also
setting 'report_errors' when matching.
Some housekeeping was also done...
The offset option also did not properly check for offset's >= 0.
Change nomatch to BADARG when pre-compiled mp() is faked:
By constructing a 5-tuple with faked content but the right data types,
you could do a re:run which returned nomatch when in fact the mp() was
bad. The cheapest solution is to check the return from pcre_exec
better.
Remove unreachable code in erts_bif_re.c:
Replaced tests for things that logically simply
cannot happen with ASSERT.
