* hans/crypto/enable_aes_ctr/OTP-15829: crypto: Re-enable aes_ctr for openssl cryptolib < 1.0.1
2019-05-29stdlib: Fix a bug concerning io_lib option 'chars_limit'Hans Bolinder
See also https://bugs.erlang.org/browse/ERL-957.
2019-05-28Fix unsafe optimizations where guard tests could be removedBjörn Gustavsson
A repeated test could be optimized away. Example: bar(A) -> if is_bitstring(A) -> if is_binary(A) -> binary; true -> bitstring end; true -> other end. In the example, the `is_binary/1` test would be optimized away, basically turning the example into: bar(A) -> if is_bitstring(A) -> bitstring; true -> other end. Thanks user Marcus Kruse in the Elixir forum for noticing this bug.
2019-05-28Eliminate crash in the beam_ssa_dead compiler passBjörn Gustavsson
The compiler could crash in the beam_ssa_dead pass while compiling complex nested `case` expressions. See the added test case for an example and explanation. https://bugs.erlang.org/browse/ERL-956
2019-05-27Fix compiler crash in beam_exceptBjörn Gustavsson
The compiler would crash in `beam_except` while compiling this function: bar(Req) -> ok = case Req of "POST" -> {error, <<"BAD METHOD ", Req/binary>>, Req}; _ -> ok end. https://bugs.erlang.org/browse/ERL-954

2019-05-27Fix loading of Core Erlang code for extracting a map elementBjörn Gustavsson
The following Core Erlang code could not be loaded: 'f'/1 = fun (_1) -> case <_1> of <~{'foo':='foo'}~> when 'true' -> _1 end Loading would fail with the following message: beam/beam_load.c(2314): Error loading function example:f/1: op i_get_map_element_hash p x a u x: no specific operation found https://bugs.erlang.org/browse/ERL-955
2019-05-24Fix unsafe negative type inferenceBjörn Gustavsson
The type optimizer pass (`beam_ssa_type`) could make unsafe negative inferences. That is, incorrectly infer that a variable could *not* have a particular type. This bug was found when adding another optimization. It is not clear how write a failing test case without that added optimization.
2019-05-22crypto: Re-enable aes_ctr for openssl cryptolib < 1.0.1Hans Nilsson
It was accidently disabled in the crypto:supports/0 and /1. It worked however in the encrypt/decrypt functions.
2019-05-21Eliminate compiler crash when compiling complex receive statementsBjörn Gustavsson
Certain complex receive statements would result in an internal compiler failure. That would happen when the compiler would fail to find the common exit block following a receive. See the added test case for an example. https://bugs.erlang.org/browse/ERL-950
2019-05-20Fix non-terminating compilationBjörn Gustavsson
The compiler would not terminate while compiling the following code: foo(<<N:32>>, Tuple, NewValue) -> _ = element(N, Tuple), setelement(N, Tuple, NewValue). The type analysis pass would attempt to construct a huge list when attempting analyse the type of `Tuple` after the call to `setelement/3`. https://bugs.erlang.org/browse/ERL-948

TLS connections should not buffer too much application data if they want to benefit from TCP flow control. Certain applications may want to customize the value of internal_active_n as there is a tradeoff between buffering memory and throughput. Conflicts: lib/ssl/src/tls_connection.erl

2019-05-07kernel: Force synchronous port_commands in user/user_drvJohn Högberg
Banging data to a local port was always synchronous prior to Erlang/OTP R16, and these modules relied on that behavior to report that data had successfully been enqueued on the stdout port. This would cause data to be silently dropped if the command didn't run synchronously and the emulator halted before the port received the data. This was fairly rare in practice, but could be seen from time to time on Windows with escripts that ended with a call to io:format/2, such as the one used by the escript_SUITE:create_and_extract test. This is a minimal band-aid to make things reliable again. A more complete fix would add explicit synchronization with the port.

* dgud/mnesia/pr-2216/OTP-15084: Report stacktrace in non-transactions activity function errors.
2019-05-07Report stacktrace in non-transactions activity function errors.Daniil Fedotov
If an activity function fails with an error, the stacktrace is dropped in non_transaction function try/catch clause. This makes debuging of errors inside a transaction really hard. Transaction activities handle errors and exits differently, non-transaction activities should do the same. Adding the stacktrace to the exit reason when translating errors to exits.

A smallish selection of already existing tests, run with the indentation option.
2019-05-07dialyzer: Add an --no_indentation optionHans Bolinder
By default Dialyzer tries to improve the readability of warnings. Newlines are inserted before and inside types, signatures, and Erlang code. Sometimes the newlines look misplaced. The raw format (option --raw) is not affected. Use the new --no_indentation option get the old behavior (no inserted line breaks). A note on the implementation. The types &c present in the warning tuples are parsed, and then formatted using erl_pp, the Erlang Pretty Printer. The alternative, to create message tuples with formatted types, turned out to more complicated, and has no real benefits. Also notice that the fixes for binaries (commit 9db8a098) and union elements (commit a1e51d12) are required. As a consequence, messages created before these commits using the --raw option cannot always be indented.
