2015-05-12ssl: add ssl:connection_information/[1,2]Qijiang Fan
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

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: 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

2015-04-20zip: Suppress a dialyzer warning for an unmatched returnBjörn Gustavsson
A warning for an unmatched return was introduced in aaa7c917. The caller of openzip_close/1 ignores the return value, which could be an error tuple. In this situation, handling a fatal error, it is OK to ignore the return value; thus, we only need to make it explicit that we are ignoring the return value.

2015-04-15Document the new {badmap,Term} and {badkey,Key} exceptionsBjörn Gustavsson
2015-04-15Raise more descriptive error messages for failed map operationsBjörn Gustavsson
According to EEP-43 for maps, a 'badmap' exception should be generated when an attempt is made to update non-map term such as: <<>>#{a=>42} That was not implemented in the OTP 17. José Valim suggested that we should take the opportunity to improve the errors coming from map operations: http://erlang.org/pipermail/erlang-questions/2015-February/083588.html This commit implement better errors from map operations similar to his suggestion. When a map update operation (Map#{...}) or a BIF that expects a map is given a non-map term, the exception will be: {badmap,Term} This kind of exception is similar to the {badfun,Term} exception from operations that expect a fun. When a map operation requires a key that is not present in a map, the following exception will be raised: {badkey,Key} José Valim suggested that the exception should be {badkey,Key,Map}. We decided not to do that because the map could potentially be huge and cause problems if the error propagated through links to other processes. For BIFs, it could be argued that the exceptions could be simply 'badmap' and 'badkey', because the bad map and bad key can be found in the argument list for the BIF in the stack backtrace. However, for the map update operation (Map#{...}), the bad map or bad key will not be included in the stack backtrace, so that information must be included in the exception reason itself. For consistency, the BIFs should raise the same exceptions as update operation. If more than one key is missing, it is undefined which of keys that will be reported in the {badkey,Key} exception.

2015-04-10Speed up timer_simple_SUITE:timer_perf/1Björn Gustavsson
In big_test/1, there is 9 seconds sleep before spawning any timers. Why? Before the sleep nrev processes are started, but they are likely to finish running before the 9 seconds have elapsed. Since I see no reason at all for the sleep, I will remove it.
2015-04-10Speed up timer_SUITEBjörn Gustavsson
The single test case in timer_SUITE is annoyingly slow. On average, its running time is about 4 minutes (estimated by a back-of-the-envelope calculation). Scale down the delay times in the main loop and the length of timers started. The running average time should now be around 80 seconds.
2015-04-10Optimize gen_server_SUITE:hibernate/1Björn Gustavsson
The running time for gen_server_SUITE:hibernate/1 is about 12 seconds because of 1000 ms sleeps in the test case. Introduce a helper function to avoid sleeping more than necessary. While we are it, also remove all ?line macros in the test case.

The running time for gen_event_SUITE:hibernate/1 is about 20 seconds because of 1000 ms sleeps in the test case. Introduce helper functions to avoid sleeping more than necessary. While we are it, also remove all ?line macros in the test case.
