2014-12-19erts: Make main thread safe from pipe closed eventLukas Larsson
2014-12-19erts: Improve crash dumpsLukas Larsson
This commit improves crash dumps in several ways: * Suspends schedulers to get a current snapshot * Dumps information about scheduler * Dumps stack trace of current running process (including Garbing processes)
2014-12-19erts: Rename sys_sigset to sys_signalLukas Larsson
Also removed old legacy fallback that is no longer used
2014-12-19erts: Introduce thread suspend functionsLukas Larsson
These functions allow any thread to suspend any other thread immediately and then resume all threads. This is useful when doing a crash dump in order to get a more accurate picture of what state the system is in.

2014-12-02erts: Fix finite warning for clangLukas Larsson
clang aka llvm claims to be __GNUC__ and thus we have to explicitly check that it is not used.

2014-11-24erts: Use finite instead of isfinite with gccLukas Larsson
Turns out that isfinite emits a function call and not an instruction in gcc, this makes estone float arith about 50-75% slower. finite emits the instruction so we use that instead.

2014-10-30erts: Fix hanging in fd_stop on windowsLukas Larsson
When reaping ports the flushReplyEvent is not signalled and therefore an errornous loop check caused the emulator to hang forever during shutdown.

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.

2014-10-20Merge branch 'lukas/erts/non-blocking-shell'Lukas Larsson
* lukas/erts/non-blocking-shell: Fix io:columns/0 timeout when invoked via user kernel,ssh: Add synchronous user_drv protocol erts: Make writing to non-tty fds non-blocking erts: Make tty driver non-blocking
2014-10-16erts: Make writing to non-tty fds non-blockingLukas Larsson
If the fd_driver is given non-tty fds it will now use an async thread instead of doing a blocking write. An example of a non-tty fd is the fd used by stderr, but could be anything handed down to the driver.
2014-10-16erts: Make tty driver non-blockingLukas Larsson
Instead of using blocking call to fwrite, the tty driver now uses non-blocking calls to writev and queues any output data that cannot be written into the driver queue. Without this change an stdout write could block an entire scheduler if for some reason the pseudo tty on the other side does not consume the output of the Erlang shell. OTP-12239

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.

* 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.

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.
