2017-02-03Store messages for 'rex' and 'error_logger' off heapBjörn Gustavsson
Performance for processes that receive huge amounts of messages can be increased by storing the incoming messages outside the heap (that avoids copying the message in a garbage collection). Two OTP processes that are known to receive many messages are 'rex' (used by 'rpc') and 'error_logger'.

2016-11-29Improve caching in disk_logRichard Carlsson
Avoid starting timers for flushing when the written data is empty or larger than the max cache size. Previously, a single huge write to an empty cache would be put in the cache until the next write or the timer event. Also increase the cache size from 16K to 64K.

These functions use the MD5 beam/native checksum to determine whether the code for a module has changed on disk and is a candidate for loading.

2016-11-21Remove vestiges of watchdog support in heartMagnus Henoch
Hardware watchdog support was removed from heart in R13A, but there were still some vestiges in the code and the documentation. - Remove mentions of the HW_WD_DISABLE variable, as it's no longer used. - Remove the HEART_BEAT_BOOT_DELAY variable, as it was only used for the hardware watchdog.

* sverker/kernel-erts-dependency: kernel: Add lost dependency to erts-8.1
2016-10-31kernel: Add lost dependency to erts-8.1Sverker Eriksson
In OTP-19.1 (c70ca686fe269db6079a2ca1c7e09cdfc0cfa903) erts_code_purger:finish_after_on_load/2 was added and called by code_server.erl.
2016-10-27controlling_process can return {error, badarg}Péter Gömöri
For gen_tcp, gen_udp and gen_sctp controlling_process/2 can return badarg if erlang:port_connect/2 fails with badarg. This can easily happen if the new owner is not alive but in some race condition also when the socket is closed right before port_connect/2 (and after the previous socket function) This commit documents this behaviour.

2016-10-18Code cleanup to remove confusing assertionKostis Sagonas
The code of add_ref/6 contained an assertion that somehow appeared twice. Also, a recent commit (2b2de61) suppressed an unmatched return warning in a non-optimal way. By changing the return type of hipe_bifs:add_ref/2 to be 'ok' instead of [] the code can be cleaned up and simplified. While at it, fixed the wrong indentation of some nearby code.

2016-10-14erts: Move new hipe ref and sdesc lists to loader stateSverker Eriksson
2016-10-14Add a loader state for HiPE code loadingMagnus Lång
Just like the BEAM loader state (as returned by erlang:prepare_loading/2), the HiPE loader state is contained in a magic binary. Eventually, we will separate HiPE loading into a prepare and a finalise phase, like the BEAM loader, where the prepare phase will be implemented by hipe_unified_loader and the finalise phase be implemented in C by hipe_load.c and beam_load.c, making prepare side-effect free and finalise atomic. The finalise phase will be exposed through the erlang:finish_loading/1 API, just like the BEAM loader, as this will allow HiPE and BEAM modules to be mixed in the same atomic "commit". The usage of a loader state makes it easier to keep track of all resources allocated during loading, and will not only make it easy to prevent leaks when hipe_unified_loader crashes, but also paves the way for proper, leak-free, unloading of HiPE modules.
