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.

`ordsets:union/1` is not especially efficient when calculating the union of many ordsets. Rewrite it to use the highly optimized `lists:umerge/1`.

* kjell/stdlib/ets_ordered_set_slow_react/OTP-15906: ETS ordered_set: Improvements to the CA tree implementation
2019-06-18ETS ordered_set: Improvements to the CA tree implementationKjell Winblad
This commit only affects the implementation of ETS `ordered_set` tables with the `write_concurrency` option enabled. Such tables are implemented with a data structure that is called the contention adapting search tree (CA tree). This commit introduces the following changes: * This commit causes a join to be triggered in one randomly selected base node in about one of 1000 read unlock calls for base node locks. No such joins happened before this commit. Before this commit, operations that only acquired looks in read-mode never triggered any contention adaptation. Therefore, the CA tree could get stuck in a sub-optimal state in certain scenarios. This could happen, for example, when a CA tree is first populated with parallel inserts (which will cause splits of base nodes) and then only read-only operations are applied to the data structure. Benchmark results from the `ets_SUITE:lookup_catree_par_vs_seq_init_benchmark/0` benchmark function (which is included in this commit) shows that this change can improve the throughput of the CA tree in the scenario described above. * Read-only operations will now also increase values of statistics counters when they detect that they need to wait for other operations. Only write operation changed statistics counters before this commit. This improves the statistics that the adaptation heuristics is based on. * Additionally, this commit adds an upper and lower limit to the contention statistics variables in the base nodes. Such limits did not exist before this commit. This should, for example, make the CA tree more responsive to contention after long periods of low contention.

2019-05-03stdlib: Do not allow specs for functions in other modulesHans Bolinder
See also https://bugs.erlang.org/browse/ERL-845. [Kostis:] My suggestion is that the compiler refuses to compile modules that contain specs for functions that are not from this module. I do not remember when / why this `feature' was introduced, but thinking about it I see a lot of (ugly) semantics issues with it. For example, should one be allowed to declare in the foo module that lists:flatten/1 takes an integer() as an argument and returns a binary()? Should one be allowed to declare a spec in some module m1 for a function of m2 that is not defined in m2? There are all kinds of checks that will need to be added to dialyzer to protect itself from these semantics issues. The compiler already refuses to compile modules that contain specs for non-existing functions of the module. Similarly, it should refuse to compile modules that contain specs for functions of other modules - unless it can somehow check that these functions are indeed defined, but it is not how the compiler currently works.

2019-05-02Remove description of structure of opaque type `gb_trees:tree/2`.Brujo Benavides
Since it's an opaque type, its internal structure shouldn't be part of the docs. Otherwise it leads misguided devs to the assumption that they can pattern-match on it, when they shouldn't.
