* saleyn/float_to_list_2/OTP-10837: Fix memory leak in error case Use macros instead of constants float_to_list/2 changed rounding and cosmetic cleanup
2013-02-13Use macros instead of constantsLukas Larsson
This is needed as C90 (and therefore the win32 compiler) does not allow constants to be calculations based on other constants.

Previous default was 5.
2013-02-11erts: Evict old cached segments for newer onesBjörn-Egil Dahlberg
2013-02-11Make prim_file skip invalid filenames in unicode modePatrik Nyblom
The fix affects list_dir and read_link. Raw filenames are now never produced, just consumed even if +fnu or +fna is used on Linux etc. This also adds the options to get error return or error handler warning messages with +fn{u|a}{i|w|e} as an option to erl. This is still not documented and there needs to be other versions of read_dir and read_link to facilitate reading of all types of filenames and links. A check that we will not change to an invalid directory is also needed.
2013-02-07erts: Refactor mseg cacheBjörn-Egil Dahlberg
Use double ended cache queues to evict oldest cache first
2013-02-07float_to_list/2 changed rounding and cosmetic cleanupSerge Aleynikov
Changed rouding to round half-way up instead of down. Cosmetic cleanup and error handling of additional edge cases.

2013-01-21Text representation of a float formatted using given options.Serge Aleynikov
This BIF solves a problem of float_to_list/1 that doesn't allow specifying the number of digits after the decimal point when formatting floats. float_to_list(Float, Options) -> string() Float = float() Options = [Option] Option = {decimals, Decimals::0..249} | {scientific, Decimals::0..249} | compact Returns a string which corresponds to the text representation of a `Float` formatted using given options. When decimals option is specified the returned value will contain at most `Decimals` number of digits past the decimal point. When `compact` option is provided the trailing zeros at the end of the list are truncated (this option is only meaningful together with the `decimals` option). When `scientific` option is provided, the float will be formatted using scientific notation with `Decimals` digits of precision. If `Options` is `[]` the function behaves like `float_to_list/1`. When using `decimals` option and the number doesn't fit in the static internal buffer of 256 bytes the function throws `badarg`.

2012-12-14erts: Do not cache segments that are misalignedBjörn-Egil Dahlberg
* SBC may realloc carriers to misaligned addresses which is perfectly fine. However, those segments may not be cached because MBC allocations might find them and MBC's *needs* correct alignment.

2012-12-14erts: Use aligned bits as constant in mseg_allocBjörn-Egil Dahlberg
HAVE_SUPER_ALIGNED_MB_CARRIERS is always true with mmap and thus aligned bits is a constant and so is "page" size for mmap. Conflicts: erts/emulator/sys/common/erl_mseg.h

2011-12-27Include wakeup pipe in /dev/poll poll-set also on non-SMPRickard Green
I/O events could potentially be delayed for ever when enabling kernel-poll on a non-SMP runtime system executing on Solaris. When also combined with async-threads the runtime system hung before completing the boot phase. This bug was introduced in erts-5.9/OTP-R15B.
