2015-05-14Speed up linting by not traversing filenames in erl_annoJosé Valim
Compilation on Erlang 18.0-rc2 is about 10% slower than in Erlang 17. After some debugging, we have noticed that linting is on average 30% to 50% slower being the main responsible for the performance reduction. Later profiling revealed is_filename/1 to be the biggest culprit. The change in this commit brings compilation times to about the same times as Erlang 17. Note this commit doesn't change the compiler behaviour compared to Erlang 17 because we didn't sanity check the value given to the file annotation in the past. I would say checking the filename is not worth it if it means compilation becomes 10% slower on average. After all, there are many places in the compiler where it will fail if we give it a malformed tree, I wouldn't then special case file annotation.
2015-05-14Cache nowarn_bif_clash functions in erl_lintJosé Valim
When compiling parser files, because they rely heavily on inline annotations, retrieving the nowarn_bif_clash information from the compiler options is expensive. This patch stores nowarn_bif_clash in the lint record. By using erlc +'{eprof,lint_module}' when compiling the erlang parser, we noticed the time spent on nowarn_function/2 reduced from 30% to 0.01%.

This commit adds a new function, ssl:connection_information/[1,2] to retrive the connection information from a SSLSocket. And also, this deprecates a function ssl:connection_info/1, and reimplements connection_info/1 with the new function.

2015-05-08digraph: export label typeDavid Kubecka
Together with vertex and edge, label is a core type of digraph module according to documentation and therefore should be exported as well.

2015-05-06Correct filename:split(<<"">>)Björn Gustavsson
filename:split("") returns [], while filename:split(<<"">>) returns [<<"/">>]. Since the support in the filename module for binary arguments is much more recent than support for strings, change filename:split(<<"">>) so that it returns []. Noticed-by: KOUCHANG

2015-04-30stdlib: Document and add normal distributed random value functionDan Gudmundsson
It is needed in various tests. It uses the Ziggurat algorithm, which is the fastest that I know.
2015-04-30Ensure that erl_anno is used when building the primary bootstrapBjörn Gustavsson
As the erl_anno module is used by the compiler, it must be included in the set of modules that are used when building the primary bootstrap.
2015-04-30stdlib: Silence some of qlc's warningsHans Bolinder
As long as the Erlang Compiler and qlc do not agree on the location of LC warnings, qlc's own warnings about patterns and filters that always fail have been silenced.
2015-04-30stdlib: Use module erl_annoHans Bolinder
2015-04-30stdlib: Add module erl_annoHans Bolinder
Introduce erl_anno, an abstraction of the second element of tokens and tuples in the abstract format. The convention that negative line numbers can be used for silencing compiler warnings will no longer work in OTP 19; instead the annotation 'generated' is to be used.
2015-04-29stdlib: Add new random functionality/moduleKenji Rikitake
The old random module contains an old algorithm which have flaws and the api requires the user to invoke seed and or checking if seed have been invoked, if a non constant seed is to be used. The api contains the following features: - The user can invoke rand:unform/[0|1] directly and get a non constant seeding. - The api is split in functional and non functional functions, i.e. usage of _s functions will not affect the process dictionary. - The api contains several algorithms with different characteristics and can be extended with new algorithms in the future. - Contains state of the art random number generators. - Default algorithm is taylor made for erlang to be fast on 64bits machines.

2015-04-22supervisor: Correct restart handlingBjörn Gustavsson
fbaa0bec replaced the use of now/0 with erlang:monotonic_time/1 but at the same time introduced a bug in inPeriod/3 so that it would always return 'true' (the subtraction Time - Now would always result in a non-positive number that would always be less than Period). The symptoms of the bug is that when a child has been restarted the maximum number of times allowed, the supervisor will terminate, regardless of how much time that elapses between the restarts. There was no test case that detected this problem. Add the missing test case to ensure that this bug stays killed. Reported-by: Rafał Studnicki
