2014-11-03Merge branch 'sverk/yielding-distr-send/OTP-12232'Sverker Eriksson
* sverk/yielding-distr-send/OTP-12232: erts: Add constant TERM_TO_BINARY_MEMCPY_FACTOR erts: Optimize some repeated calls to {E,W}STACK_PUSH erts: Yield in term_to_binary when encoding big maps erts: Remove unnecessary goto for fun encoding erts: Yield in term_to_binary while copying large binaries erts: Implement yielding for distributed send of large messages
2014-09-04erts: Refactor binary allocation interface to also initialize BinarySverker Eriksson
except the reference counter 'refc', as different callers have different strategies regarding the lifetime of the binary.
2014-08-29erts: Implement yielding for distributed send of large messagesSverker Eriksson
Use same mechanism as term_to_binary to yield while encoding large messages for distributed send.
2014-03-12Pass full strings to DTrace probesMichal Ptaszek
Whenever string is passed as an argument to a DTrace probe, its length should be properly computed. Until now in order to get length of the input buffer size_of(char *) was used - which evalutes to 4 or 8 (depending on the architecture). To get a proper length, size_of(DTRACE_CHARBUF_NAME(buffer_name)) should be used.

2013-09-30erts: Refactor the ASSERT macroSverker Eriksson
Introduce unconditional ERTS_ASSERT and use that for both ASSERT and ASSERT_EXPR.
2013-05-16Change rwlock to rlock where possibleLukas Larsson
Having rwlock could cause high unneccesary contention on the dist table when calling erlang:nodes() from many schedulers at the same time.

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.

2012-03-22Add user tag spreading functionality to VM and use in filePatrik Nyblom
User tags in a dynamic trace enabled VM are spread throughout the system in the same way as seq_trace tokens. This is used by the file module and various other modules to get hold of the tag from the user process without changing the protocol.

2011-11-17external.c: Remove the option to create over-sized heap binariesBjörn Gustavsson
Since refc binaries are now supported in literal pools, there is no longer any need to allow the creation of over-sized heap binaries.
2011-11-13Merge branch 'rickard/thr-progress-block/OTP-9631'Rickard Green
* rickard/thr-progress-block/OTP-9631: Replace system block with thread progress block
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.
2011-10-26Use the proper macros in all BIFsBjörn Gustavsson
As a preparation for changing the calling convention for BIFs, make sure that all BIFs use the macros. Also, eliminate all calls from one BIF to another, since that also breaks the calling convention abstraction.
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.
