2019-07-01erts: Fix integer overflow in list subtractionJohn Högberg
CMP_TERM returned an `Sint`, which overflowed the `int` used in erl_rbtree for storing the comparison, causing list subtraction to behave strangely.

2019-03-07erts: Remove ets traversal yielding if heap fragmentSverker Eriksson
Many heap fragments do no longer make the GC slow. Even worse, we are not guaranteed that a yield will provoke a GC removing the fragments, which might lead to a one-yield-per-bucket scenario if the heap fragment(s) still remains after each yield.
2019-03-05stdlib: Correct and optimize pretty printing of stringsHans Bolinder
Avoid traversing all of the list/string when only part of it will be used. An explicit check that the list is flat is needed since string:slice() accepts deep lists and more.

Fix bug in binary:encode_unsigned causing a read of uninitialized memory
2019-01-31Optimize calendar:gregorian_days_to_date/1Stanislav Mayorov
This patch improves the performance of calendar:gregorian_days_to_date/1 by changing the algorithm for finding the year to log-logarithmic. The old implementation has linear complexity, which makes function too slow for large values. For example: There is an API that allows you to create events for future dates. There are users of this API who, for some reasons, choose dates very far in the future. In such conditions, function works very slow. New implementation based on interpolation search, takes 1 or 2 iterations at most cases and free from such a flaw. A unit test was also developed to illustrate the speed of a function at large values.

* dgud/stdlib/unicode-binary-bug/ERL-777/OTP-15428: unicode_util did not handle binary input data correctly
2018-11-29stdlib: Let calendar:system_time_to_rfc3339() keep fractionsHans Bolinder
RFC3339 mentions in paragraph 5.1 that if certain conditions are fulfilled, then sorting date and time strings results in a time-ordered sequence. One of the conditions is that the strings must have the same number of fractional second digits. This commits makes sure this is indeed the case.
2018-11-21Fix inadvertently suppressed warning for unused variableBjörn Gustavsson
An external fun could inadvertently suppress warnings for unused variables, such as in this example: bug() -> BugVar = foo(), if true -> fun m:f/1 end. There would be no warning that `BugVar` was unused. The bug was introduced in ff432e262e652, which was the commit that extended external funs to allow variables. https://bugs.erlang.org/browse/ERL-762

* john/erts/OTP-18.3.4/minusminus_trapping/OTP-15371: Optimize operator '--' and yield on large inputs
2018-11-05Optimize operator '--' and yield on large inputsJohn Högberg
The removal set now uses a red-black tree instead of an array on large inputs, decreasing runtime complexity from `n*n` to `n*log(n)`. It will also exit early when there are no more items left in the removal set, drastically improving performance and memory use when the items to be removed are present near the head of the list. This got a lot more complicated than before as the overhead of always using a red-black tree was unacceptable when either of the inputs were small, but this compromise has okay-to-decent performance regardless of input size.
