2013-04-04Consistent definition of priority levelsKostis Sagonas
In the specs and the documentation of the spawn_opt family of functions there is the following definition of priority levels: Level = low | normal | high However, the process_flag/1 function in that module reads: process_flag(Flag :: priority, Level) -> OldLevel Types: Level = OldLevel = priority_level() priority_level() = low | normal | high | max This is clearly inconsistent. Change specs to use the process_level() type declaration instead of re-defining it in various places.

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`.

2012-02-21Break apart erlang:load_module/2 into two separate BIFsBjörn Gustavsson
Introduce two new BIFs, erlang:prepare_loading/2 and erlang:finish_loading/1, and re-implement erlang:load_module/2 in Erlang code. We have two reasons for doing this: * To facilitate suspending a process if another process is already doing code loading. * In the future, we can implement parallel and atomic loading of several modules. Atomic loading works except for modules with on_load handlers. Because of that issue, erlang:finish_loading/2 will currently only accept a list with a single magic binary.

2012-02-07Reintroduce sensitive BIFs in erl_bif_typesPatrik Nyblom
This involves exception BIF's, guar BIF's and some other complicated BIF's Also some minor corrections to documentation and specs in erlang.erl Added comment for each spec in erlang.erl shadowed by erl_bif_types. Dialyzer test should now run well except for one or two cases.
2012-02-07Correct dializer errors in erlang.erl and othersPatrik Nyblom
New errors found when adding specs to erlang.erl and removing them from erl_bif_types are examined and corrected. Some errors was due to faulty specs, while others were actual errors in the code using BIF's.

aa_mem_data/2 is only called by aa_mem_data/1 and itself. aa_mem_data/1 called with the argument 'notsup' will never call aa_mem_data/2. aa_mem_data/2 will only call itself with a #memory{} record as the first argument. QED. Noticed-by: Dialyzer.

2011-11-13Optimize memory allocationRickard Green
A number of memory allocation optimizations have been implemented. Most optimizations reduce contention caused by synchronization between threads during allocation and deallocation of memory. Most notably: * Synchronization of memory management in scheduler specific allocator instances has been rewritten to use lock-free synchronization. * Synchronization of memory management in scheduler specific pre-allocators has been rewritten to use lock-free synchronization. * The 'mseg_alloc' memory segment allocator now use scheduler specific instances instead of one instance. Apart from reducing contention this also ensures that memory allocators always create memory segments on the local NUMA node on a NUMA system.
2011-07-06Remove deprecated concat_binary/1Björn Gustavsson
concat_binary/1 was deprecated in R13B04, but already in the R10B-2 release, the documentation recommends using list_to_binary/1 instead.

An incorrect spec, rpc:yield/1, has been fixed.
