erlexec adds $ROOT/erts-<vsn>/bin and $ROOT/bin first in $PATH on
startup, but didn't do so if they were in the $PATH already, which
meant that the bindir didn't point to the current release after a
downgrade.

|
The retry loop wasn't working anyway as it tested fd<0
instead of res.
So, there is no real semantic change here.

* lukas/erts/win_user_home_dir/OTP-14691:
erts: Use PROFILE dir as home on windows
|
|
* dgud/dot_erlang/OTP-14439:
fixup! Do not load .erlang from current dir
erlc: Do not load .erlang
escript: Do not load .erlang
dialyzer: Do not load .erlang
reltool: Add no_dot_erlang bootfiles
Enable usage of no_dot_erlang in bootstrap
Do not load .erlang from current dir

Instead of using C:\Windows we use the profile path as the
home path on windows. The profile path normally resolves
to C:\Users\%USERNAME%. This fixes an issue where the default
path to the .erlang.cookie was not the same for jinterface as
for erl.

to run beam with "rr record".

|
Use 'no_dot_erlang' start script for tools. Options and
paths should be stated on the command line, via a
Makefile, rebar.config etc.
|
|
Previously you could not opt out on loading .erlang, change the
default to not load the resource file. The escript author
can invoke c:erlangrc(PathList) to find and load .erlang if needed.

Use 'no_dot_erlang' start script for tools.
Options and paths should be stated on the command line.

This refactor was done using the unifdef tool like this:
for file in $(find erts/ -name *.[ch]); do unifdef -t -f defile -o $file $file; done
where defile contained:
#define ERTS_SMP 1
#define USE_THREADS 1
#define DDLL_SMP 1
#define ERTS_HAVE_SMP_EMU 1
#define SMP 1
#define ERL_BITS_REENTRANT 1
#define ERTS_USE_ASYNC_READY_Q 1
#define FDBLOCK 1
#undef ERTS_POLL_NEED_ASYNC_INTERRUPT_SUPPORT
#define ERTS_POLL_ASYNC_INTERRUPT_SUPPORT 0
#define ERTS_POLL_USE_WAKEUP_PIPE 1
#define ERTS_POLL_USE_UPDATE_REQUESTS_QUEUE 1
#undef ERTS_HAVE_PLAIN_EMU
#undef ERTS_SIGNAL_STATE

CFLAGS weren't updated to include the sys/common directory for this build
target.

* john/erts/runtime-lcnt:
Document rt_mask and add warnings about copy_save
Add an emulator test suite for lock counting
Break erts_debug:lock_counters/1 into separate BIFs
Allow toggling lock counting at runtime
Move lock flags to a common header
Enable register_SUITE for lcnt builds
Enable lcnt smoke test on all builds that have lcnt enabled
Make lock counter info independent of the locks being counted

The implementation is still hidden behind ERTS_ENABLE_LOCK_COUNT, and
all categories are still enabled by default, but the actual counting can be
toggled at will.

* rickard/escript-space-path-fix/OTP-14433:
escript: Do not split path to Erlang system into multiple words
|
|
Fix erlang system lookup from escript bug introduced in PR #1293
OTP-14201
|
|
* dgud/erts/revert-default-process-name:
Revert setting default argv0 name
|
|
escript failed to start Erlang systems with spaces in the
absolute path (when absolute path was used).
|
|
Erlang system found in PATH was used even when explicitly pointing out
the escript binary in another Erlang system.
|
|
Changing argv[0] from emu name to progname if ESCRIPT_NAME was not set
caused to many failing scripts, revert that part of the change.

* lukas/erts/etp-processes-ports-optimization:
erts: Optimize etp-processes and etp-ports
|
|
Not calculating the max, table and invalid addresses
each loop speeds up iterating through the processes list
by about 5x.

* rickard/ds-runqs:
Make statistics/1 aware of dirty run-queues and tasks
|

|

Add the option -emu_type to start an emulator of a certain
type. For exampe, "-emu_type lcnt" will start beam.lcnt.smp.
Any string will be accepted after -emu_type. If there is no
corresponding emulator, there will be an error similar to:
erlexec: The emulator '.../bin/x86_64-unknown-linux-gnu/beam.foo.smp' does not exist.
On Windows, there is an undocumented option "-debug". Remove
that option, because -emu_type can be used instead.
|
|
"./configure --enable-lock-counter" would modify the behavior
of the default emulator (usually SMP).
To make lock counting more accessible, change --enable-lock-counter
to build an additional emulator in the same way as:
(cd erts/emulator && make lcnt)
(The next commit will make it easier to start the built lock-counter
emulator.)

instead of beam[.smp].

* rickard/timer-improvements:
Fix of later timer wheel
Minimum timeout position in each timer wheel
Manage timers to trigger at once in a slot similar to other timers
Introduce timer slot range counters
Timer wheel divided into a "soon wheel" and a "later wheel"
Remove unnecessary cancel callback from timer-wheel timers
Rearrange timer struct fields in order to simplify
Use timer wheel for short BIF timers
Use magic refs for BIF timers
Remove accessor BIF timer implementation
Fix aux-work timer implementation

* bjorn/dialyzer/add-typer/OTP-14336:
Add smoke test for TypER
Add back TypEr to the main OTP repository
|
|
It turned out that the dependencies between Dialyzer
and TypEr makes it impractical to have TypEr in a
separate repository.
Add it back to the OTP repository, but put the Erlang
module 'typer' in the dialyzer application.
|
|
|
|
Minimum known timeout position is saved in bot far and near
wheel. This information is used to avoid scanning from current
position in the cases were we know the minimum timeout position.
