2012-11-30erts: Change default of erl_crash.dumpBjörn-Egil Dahlberg
* Create an erl_crash.dump if no heart exists and no ERL_CRASH_DUMP_SECONDS is set (behaviour changed) * Don't create an erl_crash.dump if heart do exists and no ERL_CRASH_DUMP_SECONDS is set (behaviour not changed) This changes the behaviour back to the R15B02 default considering if a beam was running with no heart. The motivation is that we want a fast heart to fast restart erlang if it crashes but to be able to get non-truncated erl_crash.dumps via setting ERL_CRASH_DUMP_SECONDS if we so desire.

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.
2012-10-09crypto: Make unloading of crypto saferSverker Eriksson
Facts: crypto nif-lib registers callback functions that openssl uses for memory management and thread synchronization. The callback functions can only be set once, openssl does not allow changing the callback functions. Problem: If openssl is dynamicly linked to crypto, you might get s scenario where the crypto lib is unloaded while leaving openssl loaded with its old pointers to the unloaded crypto code intact. If crypto is then reloaded (by init:restart() for example), the crypto nif-lib might get relocated at a different address. crypto calls openssl which in turn calls the old invalid callback functions...kaboom. Solution: Break apart the callback functions into a separate dynamic lib that crypto loads with dlopen. When crypto is unloaded the callback lib is left in place to be reused if/when crypto is loaded again.

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.

Almost all uses of the 'long' datatype is removed from VM and tests Emulator test now runs w/o drivers crashing Nasty abs bug fixed in VM as well as type errors in allocator debug functions Still one allocator test that fails, domain knowledge is needed to fix that. Fix type inconsistency in beam_load causing crashes

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.
2011-06-14Use new atomic API in runtime systemRickard Green
All uses of the old deprecated atomic API in the runtime system have been replaced with the use of the new atomic API. In a lot of places this change imply a relaxation of memory barriers used.

2010-11-22ETS 'compressed' option.Sverker Eriksson
The compressed format is using a slighty modified variant of the extern format (term_to_binary). To not worsen key lookup's too much, the top tuple itself and the key element are not compressed. Table objects with only immediate non-key elements will therefor not gain anything (but actually consume one extra word for "alloc_size").

elib_malloc is an alternate memory allocator that is no longer possible to build.
2010-08-17erts: Remove stray pre-ISO-C compatibility macrosBjörn Gustavsson
A long time ago, the Erlang run-time system could be build with pre-ANSI/ISO-C (K&R) C compilers, but that is no longer possible. Remove the remaining uses of the compatibility macros that made it possible that possible.
2010-08-07Align trailing message data for all types of structuresRickard Green
Alignment of trailing data in messages has been adjusted. This in order to be able to pass data of any type as trailing data in the future.

The experimental Standalone Erlang (SAE) support based on Joe Armstrong's work has long been broken. Remove the remaining code and Makefile rules.
2010-05-20sys.h: Correct the get_int64() macroBjörn Gustavsson
The get_int64() macro has never been used (it was probably added for completeness at the same time that put_int64() was added), but it was not actually used and therefore it does not actually work.
