* sv/isfinite/OTP-12268: Use isfinite() instead of finite() when available
2014-10-28Use isfinite() instead of finite() when availableAnthony Ramine
OS X Mavericks builds result in a number of warnings about finite() being deprecated, like these: beam/erl_arith.c:451:7: warning: 'finite' is deprecated: first deprecated in OS X 10.9 [-Wdeprecated-declarations] ERTS_FP_ERROR(p, f1.fd, goto badarith); ^ sys/unix/erl_unix_sys.h:319:33: note: expanded from macro 'ERTS_FP_ERROR' ^ sys/unix/erl_unix_sys.h:244:51: note: expanded from macro '__ERTS_FP_ERROR' ^ /usr/include/math.h:718:12: note: 'finite' has been explicitly marked deprecated here extern int finite(double) __OSX_AVAILABLE_BUT_DEPRECATED(__MAC_10_0, __MAC_10_9, __IPHONE_NA, __IPHONE_NA); Add checks to use isfinite() instead of finite() where available. Verified on OS X Mavericks 10.9.5 and Ubuntu 12.04.

2014-03-26ose: fix for packet_bytes in fd/spawn driver.Jonas Karlsson
2014-03-26ose: Fix bug when hunting for signal proxyLukas Larsson
Sometimes the wrong signal, i.e. a read reply, would be received from this non-selective receive.
2014-03-26ose: Implement tcp inet driver for OSELukas Larsson
The inet driver for OSE has to handle signals instead of selects and thus the wrappers for ready_input/output are a little bit different. However the majority of the inet code remains the same.

2014-03-26ose: erlang display goes to ramlog printfLukas Larsson
2014-03-26ose: Initiate stdin/stdout/stderrLukas Larsson
Needed to get std io to work in some OSE systems where stdio is not opened when the program starts.

* paulgray/dtrace_snprintf_fix/OTP-11816: Fix DTrace/SystemTap-related formatting
2014-03-25Fix DTrace/SystemTap-related formattingScott Lystig Fritchie
Thanks to Michał Ptaszek for bringing this embarrassing formatting error to my attention. Many DTrace/SystemTap trace strings are incorrectly truncated at 4/8 bytes, depending on the CPU word size. This patch expands the work from commit d032e097 by zheng siyao.

2014-03-23ose: Reset busy port when pdq emptyLukas Larsson
2014-03-23ose: Restore the owner of the signalAdrian Mangeac
As any scheduler process can consume any message we have to make sure that the message is owned by the scheduler before returning it in erl_drv_ose_get_signal.

2014-02-24ose: Thread priorities configurable from lmconfLukas Larsson
The pattern used for getting the priority from the lmconf is based on the name of the process created. The pattern is: ERTS_%%PROCESS_NAME%%_PRIO with the %%PROCESS_NAME%% replaced by the prefix of the process the priority applies to. eg: ERTS_SCHEDULER_PRIO=24 applies to processes with name SCHEDULER_1, SCHEDULER_2 etc.
2014-02-24ose: Cleanup POLL_SCHED_1 codeLukas Larsson
Now schedulers 2..N make sure to wake sched 1 if they find that all io has been consumed and sched 1 is sleeping. Before sched 1 was spinning in sys_schedule waiting for sched 2..N to finish consuming io jobs
2014-02-24ose: Added Enea copyright header to lcf files.Robert Paal
Also removed softkernel lcf files.
2014-02-24ose: Eliminating delays when trying to open filesRobert Paal
When opening filers on not mounted volumes the default timeout on OSE is quite big and since at startup we load something like 20 beam files this slows down startup by as much as 50 seconds.
2014-02-24ose: Update ddll interface after rebase to 17.0-rc1Lukas Larsson
Also deleted all the copy-paste stuff
2014-02-24ose: Add fair scheduling yieldsLukas Larsson
This is needed on OSs that do not do round robin scheduling of threads.
2014-02-24ose: Port run_erl and to_erlLukas Larsson
2014-02-24ose: Rewrite resolve_signal API for ose driversLukas Larsson
This new API has less impact on the check_io code and also removes the callback from ErlDrvEntry. The downside is that you have to give the resolve function when creating each event. Also the mode if the resolve was removed as this mimics the win32 code and decreases complexity.
2014-02-24ose: Fix starting with pm_createLukas Larsson
For some reason starting with pm_create offsets the input argument list by one, so we have to adjust them before calling erl_start.
2014-02-24ose: Update erl_assert_error after R16B03 api changeLukas Larsson
2014-02-24ose: OSE port related cleanup and fixesJonas Karlsson
Some OSE cross-chains have problems with system includes being used, so for atleast OSE specific parts we use "" instead of <>.

2014-02-24ose: Use spinlock as default heap lock mechanismJonas Karlsson
2014-02-24ose,erts: Specify name for tsd keysLukas Larsson
This simplified debugging on OSE and also limits the number of ppdata keys that are created when beam is restarted.

2014-02-24ose: Copied driver_int.h from unixLukas Larsson
2014-02-24ose: Add module that allows interaction with any OSE processLukas Larsson
The interface of this module is made to be as generic as possible in order for other IPC mechanisms to mimic it and allow porting of code between different os:es.
2014-02-24ose: Change start way to use arguments to beam.smp directlyLukas Larsson
The old way registered a shell command that needed to be executed. This way is more flexible as you can also use the lmconf file to set arguments there.
