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.

Fixed bug in slice which wrongly could return <<>> for non-utf8 binary input. Also give a better error reason when non-utf8 binaries are given as input to some functions.

2019-04-18Fix broken ETS test caseKjell Winblad
This commit fixes an ETS test case that tests the decentralized memory counter in tables of type ordered_set with the write_concurrency option turned on. The test case assumed that the memory consumption of the table would only grow monotonically when terms are inserted. However, this was not the case when the emulator was compiled in debug mode as random splits and joins of CA tree nodes could happen. This commit fixes the test case by disabling random splits and joins in the tested table.

2019-04-12stdlib: Let the Pretty Printer output more on one lineHans Bolinder
Atomic elements such as atoms, '{}', '[]', and '<<>>' are output on the same line in types, structs, lists, &c. In particular types can be more compact, and easier to read. A space is output after comma in tuples, to be more consistent.

2019-04-12stdlib: Add option 'quote_singleton_atom_types' to erl_ppHans Bolinder
The new option can be used by Dialyzer, which has traditionally quoted singleton atom types. The OTP team has decided not to use the convention in OTP documentation, at least not for now. That is why the option is needed. EDoc does not use the new option. Syntax Tools does not have a similar option.

2019-04-10Decentralized counters for ETS ordered_set with write_concurrencyKjell Winblad
Previously, all ETS tables used centralized counter variables to keep track of the number of items stored and the amount of memory consumed. These counters can cause scalability problems (especially on big NUMA systems). This commit adds an implementation of a decentralized counter and modifies the implementation of ETS so that ETS tables of type ordered_set with write_concurrency enabled use the decentralized counter. [Experiments][1] indicate that this change substantially improves the scalability of ETS ordered_set tables with write_concurrency enabled in scenarios with frequent `ets:insert/2` and `ets:delete/2` calls. The new counter is implemented in the module erts_flxctr (`erts_flxctr.h` and `erts_flxctr.c`). The module has the suffix flxctr as it contains the implementation of a flexible counter (i.e., counter instances can be configured to be either centralized or decentralized). Counters that are configured to be centralized are implemented with a single counter variable which is modified with atomic operations. Decentralized counters are spread over several cache lines (how many can be configured with the parameter `+dcg`). The scheduler threads are mapped to cache lines so that there is no single point of contention when decentralized counters are updated. The thread progress functionality of the Erlang VM is utilized to implement support for linearizable snapshots of decentralized counters. The snapshot functionality is used by the `ets:info/1` and `ets:info/2` functions. [1]: http://winsh.me/ets_catree_benchmark/flxctr_res.html

* hasse/stdlib/erl_pp_throw/OTP-15751: stdlib: Fix a bug concerning exception class 'throw'
2019-04-09Issue an error for improper use of record_info/2 in a funBjörn Gustavsson
`record_info/2` is a pseudo-function that requires literal arguments known at compile time. Therefore, the following usage is illegal: f() -> fun record_info/2. However, `erl_lint` did not issue a compilation error for this usage, and the compiler would crash in a later pass. https://bugs.erlang.org/browse/ERL-907
2019-04-08stdlib: Fix a bug concerning exception class 'throw'Hans Bolinder
Since the introduction of the stack trace variable, the Erlang Pretty Printer has left out the exception class 'throw' even when the stack trace variable cannot be left out, which is not correct Erlang code. The fix is to always include the exception class 'throw'. An alternative is to exclude 'throw' exactly when the stack trace variable is '_'.

An appliction outside of OTP may want to reuse then name of a module that was previously included in OTP. Therefore, there should be a way to suppress warnings for removed functions.

Fails sometimes on windows due to bad timer precision leading to division by zero. This is more a (bad) benchmark than a regression test.
