2018-01-19erts: Add ERTS_RESTRICTSverker Eriksson
2018-01-19Optimize matching of an 'utf8' segment in the binary syntaxBjörn Gustavsson
Matching out an 8-bit integer is faster than matching out an utf8-encoded code point, even if the value of the code point is less than 128. The reason is that matching out an 8-bit integer is specially optimized to avoid a function call. Do a similar optimization for matching out an utf8 segment.

2018-01-17Fix slow hipe executionSverker Eriksson
particularly slow erlc when compiler is hipe compiled. hipe_unified_loader:load did not patch external call sites and instead caused a double hipe mode switch per call. hipe_unified_loader:load is only used for early modules first loaded as beam and by code:atomic_load and friends.

2018-01-15erts: Refactor and cleanup sys_double_to_chars_fastSverker Eriksson
Replace long long with Uint64
2018-01-15erts: Fix float_to_list(F, [{decimals,D}]).Sverker Eriksson
Example symptom: 1> float_to_list(0.145, [{decimals,1}]). "0.2" There were two problems in sys_double_to_chars_fast 1. Most serious was adding 0.55555555 / (10^D) instead of 0.5 / (10^D) which imposed a 5.5% risk of a faulty rounding up. 2. Using fixpoint for frac_part which lost significant bits if F < 0.5
2018-01-15erts: Fix buffer overflow bug in erts_printf %fSverker Eriksson
Sign character was not accounted for. Ex: float_to_list(-3.1265538967899625e+69, [{decimals,16}]).

2018-01-09stdlib: Improve erl_eval's stacktracesHans Bolinder
The call "erlang:get_stacktrace()" is not handled explicitly. If there are issues, they can probably be ignored since erlang:get_stacktrace/1 will be deprecated and removed.

2018-01-03Fail if ':' is passed to binary_to_integer/2Frank Hunleth
Before: 1> binary_to_integer(<<":">>, 16). 3 After: 1> binary_to_integer(<<":">>, 16). ** exception error: bad argument in function binary_to_integer/2 called as binary_to_integer(<<":">>,16) Prior to this change, both list_to_integer/2 and binary_to_integer/2 would convert strings with values between ASCII '9' up to '0'+base for base > 10. For example, when converting in base 16, you could pass ':', ';', '<', '=', '>', and '?' without getting an exception. This was due to a missing check in c2int_is_invalid_char(). This change adds the missing check and a regression test for passing ':'. It also simplifies the code and tightens up an out-of-bounds check to make it off-by-one rather than off-by-two.

Fix GC bug for HiPE primop bs_put_utf8

in order to detect incompatible changes in primop interface (which we just did for bs_put_utf8) and refuse hipe loading.
2018-01-03Fix bug in hipe primop bs_put_utf8Sverker Eriksson
by preventing it from doing GC, which generated code relies on.
2018-01-03Document that os:putenv/2 and putenv(3) modify different environmentsJohn Högberg
This is *ONLY* relevant for drivers/NIFs, so it's probably counter- productive to document it elsewhere.
2018-01-03Disallow NULs in filename-encoded stringsJohn Högberg
Previously we accepted trailing NULs, which was backwards compatible as such usage never resulted in misbehavior in the first place. The downside is that it prevented erts_native_filename_need from returning an accurate number of *actual characters*, needlessly complicating encoding-agnostic code like erts_osenv.
2018-01-03Alter erl_ddll:load dependency search path on WindowsJohn Högberg
The standard search order does not include the directory that the loaded DLL resides in, requiring dirty $PATH hacks to get things working, which is not an option now that os:putenv/2 is divorced from the OS environment.
2018-01-03Replace the libc environment with a thread-safe emulationJohn Högberg
putenv(3) and friends aren't thread-safe regardless of how you slice it; a global lock around all environment operations (like before) keeps things safe as far as our own operations go, but we have absolutely no control over what libc or a library dragged in by a driver/NIF does -- they're free to call getenv(3) or putenv(3) without honoring our lock. This commit solves this by setting up an "emulated" environment which can't be touched without going through our interfaces. Third-party libraries can still shoot themselves in the foot but benign uses of os:putenv/2 will no longer risk crashing the emulator.

It crashed due to recursive calls to alloc_util in carrier initialization test callback.
2017-12-20erts: Improve carrier pool searchSverker Eriksson
* Give back carrier to owner when put in pool with use of dd-queue. * Replace pooled_list with pooled_tree for more efficient search of all owned pooled carriers. * Remove traitor_list as it does not serve much purpose anymore. * Add HOMECOMING bit flag in crr->allctr atomic to (1) avoid double enqueue into dd-enqueue. (2) trigger read barrier in get_used_allctr for newly received carriers.
2017-12-20erts: Improve alloc_SUITE:migrationSverker Eriksson

2017-12-20erts: Refactor carrier dealloc migrationSverker Eriksson
by adding a dedicated 'homecoming_dd_block' to use in dd-queue. + Preparation for dd-queue-migration of non-empty carriers. + Get rid of ugly hack where blk->carrier pointer is overwritten by dd-queue and then have to be restored.
