2012-10-16erts: Change ERL_CRASH_DUMP_SECONDS behaviourBjörn-Egil Dahlberg
Not setting ERL_CRASH_DUMP_SECONDS will now terminate beam immediately on a crash without writing a crash dump file. Setting ERL_CRASH_DUMP_SECONDS to 0 will also terminate beam immediately on a crash without writing a crash dump file, i.e. same as not setting ERL_CRASH_DUMP_SECONDS environment variable. Setting ERL_CRASH_DUMP_SECONDS to a negative value will let the beam wait indefinitely on the crash dump file being written. Setting ERL_CRASH_DUMP_SECONDS to a positive value will let the beam wait that many seconds on the crash dump file being written. A positive value will set both an alarm in beam AND a heart timeout for restart if heart is running. This is due to the change of 'heart' behavior when 'heart' is listening for a crash.
2012-10-15erts, heart: Ensure erl_crash.dump is writtenBjörn-Egil Dahlberg
When a crash dump is about to be written and we have heartbeat enabled on a system. We need time to write it before heart explicitly kills the beam.

2012-09-05Make sure io is flushed when driver is closedLukas Larsson
Sometime when executing an tty io operation just before the emulator terminated, the io message would get lost. This commit makes sure that there is no io in the fd driver before shutting down.

2012-08-14Make get/putenv and erlexec understand UnicodePatrik Nyblom
Putenv and getenv needs to convert to the proper environment strings in Unicode depending on platform and user settings for filename encoding. Also erlexec needs to pass environment strings in an appropriate way for kernel to pick up. All environment strings on the command line, as well as home directory, is now passed in UTF8 on windows and in whatever encoding you have on Unix, kernel tries to convert all parameters and environments from UTF8 before making strings.
2012-07-31erlsrv: gracefully stop emulator on Windows shutdownJan Kloetzke
Windows will send the SERVICE_CONTROL_SHUTDOWN event to the service control handler when shutting down the system. Instead of ignoring the event, erlsrv will now invoke the stop action. Likewise, the Erlang emulator (and it's port drivers) must not quit upon reception of the CTRL_SHUTDOWN_EVENT event in the console control handler.

2011-12-27Include wakeup pipe in /dev/poll poll-set also on non-SMPRickard Green
I/O events could potentially be delayed for ever when enabling kernel-poll on a non-SMP runtime system executing on Solaris. When also combined with async-threads the runtime system hung before completing the boot phase. This bug was introduced in erts-5.9/OTP-R15B.

2011-11-13Use critical sections as mutex implementation on WindowsRickard Green
Windows native critical sections are now used internally in the runtime system as mutex implementation. This since they perform better under extreme contention than our own implementation.
2011-11-13Use generic lock-free queue for async threadsRickard Green
Queues used for communication between async threads and scheduler threads have been replaced with lock-free queues. Drivers using the driver_async functionality are not automatically locked to the system anymore, and can be unloaded as any dynamically linked in driver. Scheduling of ready async jobs is now also interleaved in between other jobs. Previously all ready async jobs was performed at once.
2011-11-13Replace system block with thread progress blockRickard Green
The ERTS internal system block functionality has been replaced by new functionality for blocking the system. The old system block functionality had contention issues and complexity issues. The new functionality piggy-backs on thread progress tracking functionality needed by newly introduced lock-free synchronization in the runtime system. When the functionality for blocking the system isn't used there is more or less no overhead at all. This since the functionality for tracking thread progress is there and needed anyway.
