2018-11-29stdlib: Let calendar:system_time_to_rfc3339() keep fractionsHans Bolinder
RFC3339 mentions in paragraph 5.1 that if certain conditions are fulfilled, then sorting date and time strings results in a time-ordered sequence. One of the conditions is that the strings must have the same number of fractional second digits. This commits makes sure this is indeed the case.
2018-11-21Fix inadvertently suppressed warning for unused variableBjörn Gustavsson
An external fun could inadvertently suppress warnings for unused variables, such as in this example: bug() -> BugVar = foo(), if true -> fun m:f/1 end. There would be no warning that `BugVar` was unused. The bug was introduced in ff432e262e652, which was the commit that extended external funs to allow variables. https://bugs.erlang.org/browse/ERL-762

2018-11-05Optimize operator '--' and yield on large inputsJohn Högberg
The removal set now uses a red-black tree instead of an array on large inputs, decreasing runtime complexity from `n*n` to `n*log(n)`. It will also exit early when there are no more items left in the removal set, drastically improving performance and memory use when the items to be removed are present near the head of the list. This got a lot more complicated than before as the overhead of always using a red-black tree was unacceptable when either of the inputs were small, but this compromise has okay-to-decent performance regardless of input size.

beam_lib: Clarify the beam() type in code and documentation OTP-15378
2018-10-19beam_lib: Remove obsolete module() from the beam() typeBjörn Gustavsson
The type `beam()` in the `beam_lib` module is confusing: -type beam() :: module() | file:filename() | binary(). It says that the module name can be used to identify the BEAM module to be accessed, but passing in the module name only works if the BEAM file is located in the current working directory because the module is not searched for in the code path. The reason that it is allowed to pass in the module name as an atom is for backward compatibility. A long time ago, atoms instead of strings were used as filenames. For that reason, `filename` and `file` still accept atoms as filenames (although the practice is frown upon). `beam_lib` accepts an atom as the filename for the same reason. To remove the confusion, remove `module()` from the type and the mention of it in the documentation. Code that uses an atom as a filename will still work, but Dialyzer will issue a warning. https://bugs.erlang.org/browse/ERL-696

2018-09-17stdlib: Allow lists with binaries in the Format argumentHans Bolinder
As a consequence of some refactoring (OTP-14983, option 'chars_limit'), the Format argument of io_lib:format() no longer accepts binaries in lists in Erlang/OTP 21.0. Note that if Format is not of type io:format(), control sequences in Format are ignored. This can result in unpredictable behaviour if, for example, the output of io_lib:format() is used as Format: if the output happens to be a string(), then control sequences are interpreted, otherwise not. A check that Format is of type io:format() will likely be introduced in Erlang/OTP 22.0. That will probably mean work for some users, but considering how unpredictable io_lib:format() is, we should try to fix that.

2018-09-12[proc_lib] Improve crash reports for single line loggingSiri Hansen
2018-09-12[logger] Remove encoding option from logger_formatterSiri Hansen
The encoding option was introduced in commit 270d909696a753af022df72a404c73f2895b4a02, to allow report callbacks to format according to a given encoding. There was, however, no connection between this encoding option, and the encoding of the device to which the logger handler was writing. Since a formatter is defined to return unicode:chardata(), and in order to avoid mismatch with the encoding of the device, the encoding option is now removed from the formatter. The handler itself must make sure that it does not write illegal data to its device.

* siri/supervisor/warn-shutdown-race/ERL-724: [supervisor] Add warning about race condition
2018-09-07[supervisor] Add warning about race conditionSiri Hansen
ERL-724: "During a 'gentle' shutdown, supervisors unlink from their children before sending shutdown signals to them. This can lead to a race condition in supervision trees, when the timeout for gentle shutdown of a parent supervisor expires and it kills a child supervisor that has just unlinked from a child of its own, leaving the child supervisor's own child still running after its supervisor is killed." This commit adds a warning about this in the documentation.
