2013-03-05erts: Fix refactor error in msegBjörn-Egil Dahlberg
Faulty number of arguments to mseg_dealloc. Problem arises if we try to compile halfword on operating system which do not have mremap. Not a supported case.

2013-02-18Add +pc {latin1|unicode} switch and io:printable_range/0Patrik Nyblom
This is the base for implementing configurable ~tp printouts, so that the user can define which characters to view as actually printable in the shell and by io_lib:format. The functionality is neither documented nor used in this commit

* 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.

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.

2013-02-07float_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.

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

2012-11-30erts: Change default of erl_crash.dumpBjörn-Egil Dahlberg
* Create an erl_crash.dump if no heart exists and no ERL_CRASH_DUMP_SECONDS is set (behaviour changed) * Don't create an erl_crash.dump if heart do exists and no ERL_CRASH_DUMP_SECONDS is set (behaviour not changed) This changes the behaviour back to the R15B02 default considering if a beam was running with no heart. The motivation is that we want a fast heart to fast restart erlang if it crashes but to be able to get non-truncated erl_crash.dumps via setting ERL_CRASH_DUMP_SECONDS if we so desire.
