This update fixes the problem with generic printouts in the html log file not having special characters escaped. Printouts made with io:format/2 and ct:pal/2 will now get special characters escaped automatically. Common Test will not attempt to escape characters printed with ct:log/2 since it is assumed that the user may want to print html tagged data using this function. A new function, ct:log/5, has been added, which offers optional escaping of characters. The latter function may also be used to print text to the log without headers and CSS class wrapping (analogue to io:format/2).

Application(s):

common_test

Commit 4cf832f1ad163f5b25dd8a6f2d314c169c23c82f erroneously removed logging of open and close of netconf connections. This is now corrected.

OTP-13388

Application(s):

common_test, test_server

The directory to which nodes started with test_server:start_node/3 writes their erl_crash.dump is changed. The crashdumps were earlier written to the directory of test_server.beam, but in later versions of Microsoft Windows this is no longer writable (even for administrators). The framework (common_test) log directory is now used instead.

The call_time tracing functionality internally used a time based on OS system time in order to measure call time which could cause erroneous results if OS system time was changed during tracing.

This functionality now use Erlang monotonic time in order to measure time. Besides fixing the erroneous results due to OS system time being used, the results are often also better since Erlang monotonic time often has better accuracy and precision.

OTP-13272

Application(s):

hipe

Fix various binary construction inconsistencies for hipe compiled code.

-- Passing bad field sizes to binary constructions would throw badarith rather than badarg. Worse, in guards, when the unit size of the field was 1, the exception would leak rather than failing the function clause match.

-- Passing bignums as field sizes to binary constructions would always fail (and always with badarg).

-- A bug in bs_init_bits that cased binary constructions to fail with system_limit if they were at least 1/8th of the actual limit.

-- Compiler crashes when matches against an integer literal whose size fits an unsigned word, but not a signed word or matches against an integer literal that whose size is larger than the largest allowed bignum.

-- Very large binary constructions that should fail with system_limit could instead fail with badarg or even succeed with a faulty result.

-- Add missing check for unit size match when inserting a binary. For example, a faulty expression like >/binary>> would succeed.

Time warp safety improvements.

Introduced the options monotonic_timestamp, and strict_monotonic_timestamp to the trace, sequential trace, and system profile functionality. This since the already existing timestamp option is not time warp safe.

Introduced the option safe_fixed_monotonic_time to ets:info/2 and dets:info/2. This since the already existing safe_fixed option is not time warp safe.
