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:unique_integer/1 instead.
2015-04-10Eliminate use of deprecated now/0 for measuring timeBjörn Gustavsson
Use erlang:monotonic_time/1 instead of now/0.
2015-04-10Eliminate use of deprecated now/0 for random number generationBjörn 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.

Symptom: ASSERT(segtab[seg_ix] == NULL) in alloc_seg() fails. Remedy: Make sure we set segment pointer to NULL in free_seg() even when we switch to smaller segtab.

2015-03-26Optimize binary_module:random_ref_comp/1Björn Gustavsson
The most expensive part of random_ref_comp/1 is do_matches_loop_comp/4. The running time was reduced from roughly 80 seconds to roughly 40 seconds on my computer when I modified the caller to pre-compile the pattern.
2015-03-26Optimize io_proto_SUITE:unicode_options_gen/1Björn Gustavsson
The time to run io_proto_SUITE:unicode_options_gen/1 on my computer was about 110 seconds. After modifying the test case so that it does several file operations in parallel the time was reduced to about 60 seconds.

2015-03-20Replace usage of erlang:now() with usage of new APIRickard Green
2015-03-20Introduce a new time APIRickard Green
The old time API is based on erlang:now/0. The major issue with erlang:now/0 is that it was intended to be used for so many unrelated things. This tied these unrelated operations together and unnecessarily caused performance, scalability as well as accuracy, and precision issues for operations that do not need to have such issues. The new API spreads different functionality over multiple functions in order to improve on this. The new API consists of a number of new BIFs: - erlang:convert_time_unit/3 - erlang:monotonic_time/0 - erlang:monotonic_time/1 - erlang:system_time/0 - erlang:system_time/1 - erlang:time_offset/0 - erlang:time_offset/1 - erlang:timestamp/0 - erlang:unique_integer/0 - erlang:unique_integer/1 - os:system_time/0 - os:system_time/1 and a number of extensions of existing BIFs: - erlang:monitor(time_offset, clock_service) - erlang:system_flag(time_offset, finalize) - erlang:system_info(os_monotonic_time_source) - erlang:system_info(time_offset) - erlang:system_info(time_warp_mode) - erlang:system_info(time_correction) - erlang:system_info(start_time) See the "Time and Time Correction in Erlang" chapter of the ERTS User's Guide for more information.

2015-03-17ssl: Add TLS-ALPN supportLoïc Hoguin
This commit adds support for RFC7301, application-layer protocol negotiation. ALPN is the standard based approach to the NPN extension, and is required for HTTP/2. ALPN lives side by side with NPN and provides an equivalent feature but in this case it is the server that decides what protocol to use, not the client. When both ALPN and NPN are sent by a client, and the server is configured with both ALPN and NPN options, ALPN will always take precedence. This behavior can also be found in the OpenSSL implementation of ALPN. ALPN and NPN share the ssl:negotiated_protocol/1 function for retrieving the negotiated protocol. The previously existing function ssl:negotiated_next_protocol/1 still exists, but has been deprecated and removed from the documentation. The tests against OpenSSL require OpenSSL version 1.0.2+.

2015-03-10Make the scanned form of the io_lib format strings available for processingRichard Carlsson
This adds three new functions to io_lib - scan_format/2, unscan_format/1, and build_text/1 - which expose the parsed form of the format control sequences to make it possible to easily modify or filter the input to io_lib:format/2. This can e.g. be used in order to replace unbounded-size control sequences like ~w or ~p with corresponding depth-limited ~W and ~P before doing the actual formatting.
