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.

2015-04-13v3_codegen: Don't sort map keys in map creation/updateBjörn Gustavsson
It is no longer necessary to sort the keys, since the loader does the sorting.
2015-04-13beam_validator: No longer require strict literal term orderBjörn Gustavsson
The BEAM loader will now sort keys for maps during loading, so beam_validator should not require the keys to be ordered any order. However, we must still ensure that literals keys are unique (which was implicitly guaranteed by the strict ordering requirement).
2015-04-13map_SUITE: Add tests of is_map/1 with literal mapsBjörn Gustavsson
To be sure that the compiler and BEAM virtual machine correctly handles literals maps, we must test it.

2015-04-10Eliminate deprecated now/0 used as timestampBjörn Gustavsson
Rewrite the code to measure and print elapsed time instead of just printing timestamps for the start and stop of each operation.
2015-04-10Eliminate use of now/0 for creating a unique filenameBjörn Gustavsson

Use erlang:timestamp/0 instead now/0 when seeding the random number generator.
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.
2015-04-10Optimize gen_event_SUITE:hibernate/1Björn Gustavsson
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.
2015-04-10Optimize gen_fsm_SUITE:hibernate/1Björn Gustavsson
The running time for gen_fsm_SUITE:hibernate/1 is almost 30 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.
2015-04-10Optimize unicode_SUITE:ex_binaries_errors* test casesBjörn Gustavsson
Refactor the code so that the error test cases for utf16 can share the code for big and little endian. Do the same for utf32. The major optimization is the observation that the following code: byte_size(unicode:characters_to_binary(List, unicode, {utf16,big}) can be replaced with: 2*length(List) which is much faster. (That optimization is not safe in general, but for the lists used in the error tests cases, it is.)
2015-04-10Optimize unicode_SUITE:binaries_errors/1Björn Gustavsson
unicode_SUITE:binaries_errors/1 is the slowest test case in unicode_SUITE. Its running time is about 50 seconds on my computer. Break apart unicode_SUITE:binaries_errors/1 into several test cases that can run in parallel.
2015-04-10binary_module_SUITE: Remove unnecessary calls to the binref moduleBjörn Gustavsson
The compile_pattern/1 function in the binref module is a dummy function. Therefore, calling binref:match/2 once with the plain pattern and once with a "pre-compiled" pattern will take twice as long, but will not help us find more errors. I shaved off one fourth of the running time for random_ref_comp/1 by eliminating the unnecessary calls to the binref module.
2015-04-09crypto: Fix undefined symbol EVP_CIPHER_CTX_newSverker Eriksson

2015-04-07ssh: fix loop bug for zero maximum_packet_size.Hans Nilsson
A channel could be opened with the 'max packet size' set to 0. The behaviour is not defined in the ssh rfc:s, and openssh does not handle that case in some special way besides looping. The introduced solution just "keep quiet" but removes the eternal loop that caused Erlang to core dump.

2015-04-07ssh: Add {active, false} to ssh listen socketIngela Anderton Andin
The ssh acceptor process listens for connections and spawns a process to handle each new connection that it accepts. The ownership of the accepted socket will be transfered to the new process that will handle the incomming messages. Before the ownership is transfered the socket should be in {active, false} or the acceptor process may receive data aimed for the connection. As the accept socket inherits the listen options we set {active, false} there.
