2017-11-09Fix deflateParams on zlib 1.2.11John Högberg
1.2.11 started bailing when avail_out==0 regardless of whether there's anything to flush or not, and there's no point in adapting the old method since it was vulnerable to bugs in other zlib versions which updated the deflate parameters even on failure. The api_deflateParams test has been expanded accordingly, and two white-box cases in zip_usage has been updated to make fewer assumptions about the output; the validity of the compressed data is what matters, not whether it's exactly the same as the test vector.

2017-11-07Emasculate writable binaries on entering an iovecJohn Högberg
The lack of this caused serious data corruption when a binary was altered after entering the queue. This went unnoticed because it was never used without erlang:iolist_to_iovec, which always emasculates binaries.

which was replaced by 'is_unicode' in 5369e34a892bfd8ab5aa98df330e3bbf19497b71 but kept for ABI compatibility in OTP-20.*.

2017-11-05fix output formatting in hipe_bifs:show_heap/1Mikael Pettersson
When the code switches from printf() to erts_printf() the output becomes garbled. Fixed by fflush()ing stdout first. Fixed formatting of the "H E A P" banner for 64-bit systems.

Fix hipe bug in binary <<X/utf32>> construction
2017-11-03Fix bug in hipe for <<X/utf32>>Sverker Eriksson
by introducing new primop 'is_unicode' with no exception (ab)use and no GC. Replaces bs_validate_unicode which is kept for backward compat for now.
2017-11-03Prevent hipe_bs_validate_unicode from doing GCSverker Eriksson
Fix for x86_64 only. The calling native code can not handle a GC as it has a raw pointer where to write the binary data. If a GC happens the data (utf32) will be written to the old deallocated heap.

* maint: erl_process_dump: Don't assume that literals can be found Remove one superfluous closing parenthesis in oam_intro.xml
2017-10-30erl_process_dump: Don't assume that literals can be foundBjörn Gustavsson
Native code does not register its literals in the code header for the loaded code. Therefore, a literal created by native code can not be found by mark_literal(). Ignore literals that can't be found instead of crashing (the crasdump_viewer will report such literals as incomplete heap data, but will not crash).

2017-10-27Correct erlang:is_builtin/3 for apply/2 and yield/0Björn Gustavsson
erlang:is_builtin(erlang, M, F) returns false for apply/2 and yield/0. The documentation for erlang:is_builtin/3 says that it returns true for BIFs that are implemented in C. apply/2 and yield/0 are implemented in C (as BEAM instructions), and therefore the correct return value is true. Also see a similar argument that was made for apply/3 in the past: http://erlang.org/pipermail/erlang-bugs/2015-October/005101.html https://bugs.erlang.org/browse/ERL-500
2017-10-25sctp: change connect to only return connect errorsJonas Falkevik
gen_sctp:connect_init/4 could return error even though the connect are in progress. I.e. connect on socket returned "in progress". The error can come from packet_inet_output() which is checking the socket for errors. The issue here is that from erlang you don't think the connect is still ongoing. But you will receive a sctp_assoc_change message later on.

2017-10-23erts: Fix so that bind correct schedulersLukas Larsson
When the cpu ids and scheduler ids don't match, the end schedulers could end up not being bound when they should be. example: > taskset -c 1-3 erl +S 4 +sbts > erlang:system_info(scheduler_bindings). {1,2,3,unbound} This fix makes it so that all cores are used to bind schedulers.

* bjorn/compiler/match-literals: Optimize instructions for comparing a register with a literal Optimize matching of literals for single-valued types
2017-10-21Optimize instructions for comparing a register with a literalBjörn Gustavsson
We can avoid calling eq() from the is_eq_exact_literal/3 and is_ne_exact_literal/3 instructions if the source operand is an immediate (since a literal is either a boxed or a list, never an immediate).
