2018-01-05stdlib: Let filelib:find_source() search subdirsHans Bolinder
The Design Principles states that an application can have Erlang source files one level below the "src" directory, and now filelib:find_source() by default searches one level below "src". The same applies to "esrc". That directory is only mentioned in filename(3).
2017-12-20stdlib: Make ets_SUITE memory check try againSverker Eriksson
as memory stats do not guarantee consistency. A typical ETS test case ends by a lot of deallocating that may now trigger homecoming carrier migration, that in turn can cause quite large inconsistencies in memory stats when same carrier is accounted for twice or not at all. And that's my theory why I now sometimes see transient discrepancies between before and after memory stats.

In OTP-20, c:c/1,2 started using the directory of the source file as default output directory. For backwards compatibility reasons this is now reversed so the current directory is used instead.

2017-06-22Support arbitrary crash report in proc_lib.Daniil Fedotov
The `error_logger_format_depth` variable is `unlimited` by default. This can cause errors when logging crash reports using sasl logger, because `io_lib:format("~P"...` does not support `unlimited` as a depth parameter. Use formatter string "~p" for unlimited depth. A way to reproduce the error: Start erl with sasl logger: erl -boot start_sasl -sasl errlog_type error -sasl sasl_error_logger tty Report arbitrary error: error_logger:error_report(crash_report, [fake_crash_report, foo]).
2017-06-12stdlib: Evaluate expressions in fun2ms bodiesHans Bolinder
The ms_transform module, used by ets:fun2ms/1 and dbg:fun2ms, evaluates constant arithmetic expressions. This is necessary since the Erlang compiler, which normally evaluates constant expressions, does not recognize the format generated by ms_transform.

2017-06-09stdlib: Add more checks of module names to the linterHans Bolinder
Unicode atoms are handled better by the Erlang code linter. Module names are checked for character codes greater than 255. This means that modules invoked after the linter can assume that module names have only Latin-1 characters.

erl_tar: Fix handling of date and time
2017-05-29erl_tar: Fix handling of date and timeBjörn Gustavsson
Since aa0c4b0df7cdc, erl_tar would write the local time (instead of the POSIX time) into the tar header for the archived files. When extracting the tar file, the extracted file could be set to a future time (depending on the time zone). We could do a minimal fix, but this seems to be a good time to rewrite the time handling to use the new features that allow file info to be read and written in the POSIX time format. First reported here: https://github.com/erlang/rebar3/issues/1554

Return error tuple on unicode normalization functions
2017-05-22Return error tuple on unicode normalization functionsJosé Valim
Prior to this patch, the normalization functions in the unicode module would raise a function clause error for non-utf8 binaries. This patch changes it so it returns {error, SoFar, Invalid} as characters_to_binary and characters_to_list does in the unicode module. Note string:next_codepoint/1 and string:next_grapheme had to be changed accordingly and also return an error tuple.

Warn for potentially unsafe use of get_stacktrace/0
2017-05-15Do not discard stacktraces on gen_server exitsJosé Valim
Prior to this patch, the stacktrace of an error or exit in a callback would always be discarded in crash reports. For example, an exit(crashed) in handle_call/3 would emit: =CRASH REPORT==== 10-May-2017::14:15:50 === crasher: initial call: gen_server_SUITE:init/1 pid: <0.201.0> registered_name: [] exception exit: crashed in function gen_server:terminate/8 (src/gen_server.erl, line 828) Note that the stacktrace is pointing to the gen_server internal terminate implementation that calls exit/1. This patch uses erlang:raise/3 so the stacktrace is not lost, allowing proc_lib to show the class, reason and stacktrace coming from the user implementation (in this case gen_server_SUITE): =CRASH REPORT==== 10-May-2017::14:16:44 === crasher: initial call: gen_server_SUITE:init/1 pid: <0.197.0> registered_name: [] exception exit: crashed in function gen_server_SUITE:handle_call/3 (gen_server_SUITE.erl, line 1529) This change is completely backwards compatible as using erlang:raise/3 will still emit the same exit reason to any linked process and monitor as before.
