2013-11-18erts: Add erlang wrappers to binary_to_termSverker Eriksson
to not expose the trapping BIF in the stacktrace when it throws badarg.
2013-11-18Execution of system tasks in context of another processRickard Green
A process requesting a system task to be executed in the context of another process will be notified by a message when the task has executed. This message will be on the form: {RequestType, RequestId, Pid, Result}. A process requesting a system task to be executed can set priority on the system task. The requester typically set the same priority on the task as its own process priority, and by this avoiding priority inversion. A request for execution of a system task is made by calling the statically linked in NIF erts_internal:request_system_task(Pid, Prio, Request). This is an undocumented ERTS internal function that should remain so. It should *only* be called from BIF implementations. Currently defined system tasks are: * garbage_collect * check_process_code Further system tasks can and will be implemented in the future. The erlang:garbage_collect/[1,2] and erlang:check_process_code/[2,3] BIFs are now implemented using system tasks. Both the 'garbage_collect' and the 'check_process_code' operations perform or may perform garbage_collections. By doing these via the system task functionality all garbage collect operations in the system will be performed solely in the context of the process being garbage collected. This makes it possible to later implement functionality for disabling garbage collection of a process over context switches. Newly introduced BIFs: * erlang:garbage_collect/2 - The new second argument is an option list. Introduced option: * {async, RequestId} - making it possible for users to issue asynchronous garbage collect requests. * erlang:check_process_code/3 - The new third argument is an option list. Introduced options: * {async, RequestId} - making it possible for users to issue asynchronous check process code requests. * {allow_gc, boolean()} - making it possible to issue requests that aren't allowed to garbage collect (operation will abort if gc should be needed). These options have been introduced as a preparation for parallelization of check_process_code operations when the code_server is about to purge a module.

2013-09-24add system_info(ets_limit)Steve Vinoski
Add system_info(ets_limit) to provide a way to retrieve the runtime's maximum number of ETS tables. Add tests and documentation for it too. Also repair the alphabetical order of system_info/1 argument descriptions in the documentation and in the erlang.erl clauses. Add new preloaded erlang.erl due to that change. Also ensure all system_info/1 clauses are represented in the erlang.xml source documentation -- a couple had been inadvertently dropped in previous commits when other clauses were added.
2013-09-09Fix incorrect values returned by integer_to_binary/2Juan Jose Comellas
When integer_to_binary/2 receives 0 or a negative number as an argument with a base that is different from 10, it will return incorrect values (<<>> in the case of 0) or it will crash (with negative numbers). This commit fixes these problems and adds tests to cover these cases.

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.

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.

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.
