New BIF os:unsetenv/1 which deletes an environment variable and
returns 'true'.
Does not change any old functionality.
Calls the libc function unsetenv(3) on UNIX and
SetEnvironmentVariableW(key, NULL) on Windows. The unicode support
is the same as for os:getenv and os:putenv.
|
|
Replaced the +MMscmgc switch with the +MMscrfsd switch. The old switch
didn't reflect what it controlled.

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.

files as delimiters.
While working on a tool that processes Erlang code and testing it against this repo,
I found out about those little sneaky 0xff. I thought it may be of help to other
people build such tools to remove non-conforming-to-standard characters.

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.

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.
