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.
2018-01-15erts: Fix buffer overflow bug in erts_printf %fSverker Eriksson
Sign character was not accounted for. Ex: float_to_list(-3.1265538967899625e+69, [{decimals,16}]).
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.

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.

A pool size of 4000 is too excessive for the common case. Change ERTS_TS_EV_ALLOC_DEFAULT_POOL_SIZE to 2048 Change ERTS_TS_EV_ALLOC_POOL_SIZE to 32

* 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.

2014-11-04erts: Make erts_printf work with non-blockingLukas Larsson
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.

Some win32 specific code does not compile with gcc (mingw-w64) since '__forceinline' is not supported by gcc. This can be avoided by defining a new macro ETHR_FORCE_INLINE similar to ETHR_INLINE.

This port has support for both non-smp and smp. It contains a new way to do io checking in which erts_poll_wait receives the payload of the polled entity. This has implications for all linked-in drivers.

2012-03-15erts: Fix memory corruption when reading topology infoSverker Eriksson
If the number of processors actually found while reading sysfs is lower than the configured value, we realloc() the cpuinfo array to the smaller size, but we then iterate it using the original configured size, thus corrupting memory beyond the allocated block.
