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.

2012-05-10Remove stale code for hybrid heap and incremental GCBjörn Gustavsson
The hybrid heap emulator was last working in the non-SMP R11B run-time system. When the constant pools were introduced in R12B, the hybrid heap emulator was not updated to handle them. At this point, the harm from reduced readability of the code is greater than any potential usefulness of keeping the code.

2011-12-02Mend the non-SMP emulatorBjörn Gustavsson
Commit 8781932b3b8769b6f208ac7c00471122ec7dd055 broke erlang:system_info(system_version) in the non-SMP emulator so that it would typically dump core. "rq:%d" was removed from the format string for erts_printf(), but the corresponding argument in the argument list was not removed, which ultimately caused "kernel-poll:%s" to be passed an integer (typically 0).

2011-12-01Remove common run-queue in SMP caseRickard Green
The common run-queue implementation is removed since it is unused, untested, undocumented, unsupported, and only complicates the code. A spinlock used by the run-queue management sometimes got heavily contended. This code has now been rewritten, and the spinlock has been removed.

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The ERTS internal system block functionality has been replaced by new functionality for blocking the system.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.
2011-11-13Optimize memory allocationRickard Green
A number of memory allocation optimizations have been implemented. Most optimizations reduce contention caused by synchronization between threads during allocation and deallocation of memory. Most notably: * Synchronization of memory management in scheduler specific allocator instances has been rewritten to use lock-free synchronization. * Synchronization of memory management in scheduler specific pre-allocators has been rewritten to use lock-free synchronization. * The 'mseg_alloc' memory segment allocator now use scheduler specific instances instead of one instance. Apart from reducing contention this also ensures that memory allocators always create memory segments on the local NUMA node on a NUMA system.
