* kjell/stdlib/map_hash_bug/OTP-15707: Fix out of memory bug in the implementation of maps
2019-03-29Fix out of memory bug in the implementation of mapsKjell Winblad
This commit fixes a bug that could cause a crash or memory usage to grow until the machine ran out of memory when adding a key-value pair to a map. This could happen when inserting a new key-value pair with a key K1 containing a binary B1 into a map M having a key K2 with a binary B2 if the following conditions were met: * size(B1) >= 4294967296 * size(B2) >= 4294967296 * size(M) >= 32 * (size(B1) rem 4294967296) == (size(B2) rem 4294967296) * the first (size(B1) rem 4294967296) bytes are the same both in B1 and B2 * substituting B1 in K1 with B2 would result in a term with the same value as K2 The root cause of the bug is that the map implementation only hashed the first (X modulo 4294967296) bytes of binaries so that different binaries could get hashed to the same hash value independently of the hash seed.

2019-03-29ssl: Correct test caseIngela Anderton Andin
Optimization to concatenate small user data packages recived closely after each other has invalidated assumptions in the test case.

2019-03-29ssl: Remove basic test group from ssl_to_openssl_SUITEIngela Anderton Andin
This group has started to fail as our default has diverged from OpenSSL defaults and we are not really interested in testing OpenSSL defaults.

2019-03-28erl_tar: Use read_ahead when reading compressed tar filesJohn Högberg
Jumping around in a compressed file is nowhere near as cheap as for uncompressed files, as it requires reading and decompressing up until the desired position. Using read_ahead will improve performance slightly.
2019-03-28kernel: Fix performance regression on reading compressed filesJohn Högberg
An internal buffer size was too small, causing a considerable performance degradation compared to OTP 20.

2019-03-27erts: Remove unsafe bs_get_binary2 optimization from loaderJohn Högberg
A load-time optimization assumed that match contexts had no further uses when a bs_get_binary2 overwrote the match context's register, and figured it would be safe to reuse the match context's memory for the resulting binary. This is no longer safe as of OTP 22, as a match context may be reused after being passed to another function.

We walk through all signal queues in the system when clearing seq_trace, so we must be prepared to encounter all kinds of signals.

2019-03-26compiler: Fully disable no_return optimizations in try blocksJohn Högberg
Validation could fail when a function that never returned was used in a try block (see attached test case). It's possible to solve this without disabling the optimization as the generated code is sound, but I'm not comfortable making such a large change this close to the OTP 22 release.

2019-03-25erts: Include external msg in need of GCLukas Larsson
When many external messages suddenly appear in the mailbox the young gen size is adjusted accordingly but it was immediately shrunk as the data was not counted towards the shrink size. This commit includes the ext dist size in the shrink calculation which means that the decode of the external messages will not trigger as many GCs which means much better performance.
