2016-02-02Better list_to_integerDmytro Lytovchenko
Now tries to use whole width of signed long (Sint) and this halves amount of multiplications needed to parse long integers. New code is 2-3 times faster than the old code for large inputs (tens and hundreds of digits), behavior should not change for small inputs. Test ran 10k times with GC forced between attempts. Was (R17): 720 el base 10: 0.14682 sec; base 16: 0.192722 sec; base 36: 0.337118 sec. 2800 el base 10: 1.794133 sec; base 16: 2.735106 sec; base 36: 4.761108 sec. 6500 el base 10: 9.316434 sec; base 16: 14.109469 sec; base 36: 25.319263 sec.

Added test for corner cases and sign bit corruption. Replaced macros with inline and hid it inside C file to not pollute global namespace Old bug in #define LG2_LOOKUP: Replaced with inline function and table recalculated for all bases 2 to 36 (was 2 to 64)

2016-01-20erl_prim_loader: Rename release_archives/0Björn Gustavsson
Rename release_archives/0 to purge_archive_cache/0 to make it clearer what it does and what it doesn't do. Also add a comment about its intended purpose. Note that release_archives/0 is not documented and is part of the experimental archive feature. Furthermore, the only uses I could find were in the test suite. I did not find any uses in the external applications relx and rebar3 applications that are known to use archives. Therefore, I think that the increased clarity is worth the small risk of breaking code.
2016-01-20erl_prim_loader: Correct timeout handling for efileBjörn Gustavsson
The timeout routine for efile was never called. While at it, eliminate the n_timeouts field and simplify the logic.
2016-01-20erl_prim_loader: Correct purging of the archive cacheBjörn Gustavsson
prim_do_release_archives/3 can't make up its mind whether the primary archive should be released or not. The key in the process dictionary is kept, while #prim_state.primary_archive is cleared. It seems that intent was the primary archive should be preserved, because the function was intended to be called by a timeout routine every sixth minute (it is not because of a bug in setting up the timeout). Therefore, rewrite the code to preserve the primary archive and simplify it while at it. Also, rename prim_release_archives/1 to prim_purge_cache/0 to make it clearer what it is doing.
2016-01-20erl_prim_loader: Remove unused 'cache' fieldBjörn Gustavsson
The #prim_state.cache' field is unused. The actual cache is kept in the process dictionary.

2016-01-13erts: Optimize erlang:check_process_codeSverker Eriksson
by ignoring literals. erts_internal:check_process_code will be called again anyway (with option {copy_literals, true}) before the module is actually purged. No need to check literals twice.
2016-01-13erts: Refactor check_process_code/3Sverker Eriksson
Move impl from erlang to erts_internal. Cut and paste.

2016-01-13erts: Move copy_literals/2 from erlang to erts_internalSverker Eriksson
as it's not a public interface.
2016-01-13erts: Make erlang:purge_module/1 safeSverker Eriksson
Problem: erlang:purge_module/1 is not safe in the sense that very bad things may happen if the code to be purged is still referred to by live processes. Introduce erts_internal:purge_module which is the same as the old erlang:purge_module BIF (except it returns false if no such old module). Implement erlang:purge_module in Erlang and let it invoke erts_code_purger for safe purging where all clogging processes first are killed.

2016-01-13erts: Refactor code:purge/1 and code:soft_purge/1Sverker Eriksson
by moving code from code_server to erts_code_purger. This is more or less a copy-paste from code_server.erl to erts_code_purger.erl. All the inner mechanics of code:purge/1 and code:soft_purge/1 are unchanged.

2016-01-11erts: Workaround memset bug in test caseSverker Eriksson
memset seen to fail with values larger than 255 on (armata) 32-bit ARM Debian with EGLIBC 2.13-38+rpi2+deb7u8 and gcc 4.6.3-14+rpi1.
2016-01-08erts: Allow -fvisibility=hidden for NIFs and driversSverker Eriksson
as is strongly recommended by gcc man page. We use __attribute__ ((visibility("default"))) to make sure the init functions are properly exported.
2016-01-08erts: Cleanup erl_driver.h for windowsSverker Eriksson
The comment is misleading and no need to "export" static windows drivers. DRIVER_INIT for dynamic windows drivers is defined in erl_win_dyn_driver.h
