Instead rely on gnu make's pre-defined RM variable which should equal 'rm -f'

2018-02-13Fix size of fmt_double()'s format_str[] bufferMikael Pettersson
fmt_double() may write up to 8 characters into its format_str[] buffer, which however only has room for 7 characters. This case could be triggered by a call to erts_printf_format() with any floating-point format that also includes #, and + or a space, which may be uncommon, but a nif or driver could issue it.

2017-10-18Buffer writing of crash dumpsBjörn Gustavsson
Writing of crash dumps were done using unbuffered IO. This is slow since many small writes are done. Use a FILE* with an allocated buffer to obtain buffered IO. I wrote a small test program that created 50000 binaries of 200 bytes each and then created a crash dump. The crash dumping was an order of magnitude faster with buffered IO than without.

2016-06-22Improve accuracy of timeouts using premature timeoutsRickard Green
Improve accuracy of timeouts using a premature timeout then return to sleep with a shorter timeout just before requested timeout. This approach is only used on certain platforms where we know it improves the accuracy of the timeouts, e.g. MacOS X.

* maint: Add configure switch --disable-saved-compile-time Fix ethread events with timeout Improve choice of clock sources at build time
2015-08-27Fix ethread events with timeoutRickard Green
Lots of pthread platforms unnecessarily falled back on the pipe/select solution. This since we tried to use the same monotonic clock source for pthread_cond_timedwait() as used by OS monotonic time. This has been fixed on most platforms by using another clock source. Darwin can however not use pthread_cond_timedwait() with monotonic clock source and has to use the pipe/select solution. On darwin we now use select with _DARWIN_UNLIMITED_SELECT in order to be able to handle a large amount of file descriptors.

The OSE port is no longer supported and this commit removed it and any changes related to it. The things that were general improvements have been left in the code.

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.

* lukas/erts/non-blocking-shell: erts: Fix big-endian issue with printf_putc
2014-12-15erts: Fix big-endian issue with printf_putcLukas Larsson
On little-endian machines, doing &int will give the smallest byte which is what we want to give to write. But on big-endian it will give the highest byte, which will always be \000 here which results in write never doing any writes. So we have to cast c to an unsigned char before passing it to write.

Now that stdout can be set as non-blocking by the ttsl driver we can no longer use putc and friends for the stdout/stderr streams. Therefore we fallback on write. OTP-12239

Code incorrectly relied on undefined C behavior. Clang and gcc 4.9 do not behave as code expected. This affected cores and processors detection on FreeBSD.
