2013-11-09Add os:unsetenv/1Martin Hässler
New BIF os:unsetenv/1 which deletes an environment variable and returns 'true'. Does not change any old functionality. Calls the libc function unsetenv(3) on UNIX and SetEnvironmentVariableW(key, NULL) on Windows. The unicode support is the same as for os:getenv and os:putenv.

2013-10-18erts: Fix segfaulting crashdump writingBjörn-Egil Dahlberg
Crashdumps initiated by out-of-memory on spawn could cause the beam to segfault during crashdump writing due to invalid pointers. The pointers are invalid since the process creation never finished. This commit remedies this problem by removing the process from crashdump printout.

2013-10-10Fix bsr bugLars Hesel Christensen
Fix bsr bug occurring when shifting a huge number a huge number of bits to the right. The bug can occur if Sint is 64 bits and int is 32 bits, causing a truncation in the big.c:I_lshift function.
2013-10-10Add bsr test data showing bug when shifting large numbersLars Hesel Christensen
Add test data demonstrating that bsr is broken when shifting a large number a huge number of bits to the right.

2013-09-25Implement platform specific aligned sys_alloc and use when supportedRickard Green
erts_sys_aligned_alloc() is currently implemented using posix_memalign if it exist, or using _aligned_malloc on Windows. If erts_sys_aligned_alloc() exist allocators will create sys_alloc carriers similar to how this was done pre-R16.
2013-09-24add system_info(ets_limit)Steve Vinoski
Add system_info(ets_limit) to provide a way to retrieve the runtime's maximum number of ETS tables. Add tests and documentation for it too. Also repair the alphabetical order of system_info/1 argument descriptions in the documentation and in the erlang.erl clauses. Add new preloaded erlang.erl due to that change. Also ensure all system_info/1 clauses are represented in the erlang.xml source documentation -- a couple had been inadvertently dropped in previous commits when other clauses were added.
2013-09-20Check all pattern arguments passed to binary:matches/2Mike Sassak
Including an empty binary as one of multiple patterns passed to binary:matches/2 would crash BEAM with: "Cannot reallocate 1342177280 bytes of memory (of type "tmp")". This ensures each pattern is valid before trying to match.
2013-09-12Remove ^L characters hidden randomly in the code. Not those used in text ↵Pierre Fenoll
files as delimiters. While working on a tool that processes Erlang code and testing it against this repo, I found out about those little sneaky 0xff. I thought it may be of help to other people build such tools to remove non-conforming-to-standard characters.
2013-09-11Fix syslog definesMatt Lewandowsky
config.h defines HAVE_SYSLOG_H whereas the sources are looking for NO_SYSLOG to be undefined. As the logic of "if feature is available" makes more sense than "if feature is not unavailable", I opted for the config.h define.

2013-09-10fix system_flag(scheduling_statistics,disable)Steve Vinoski
Clear the "enabled" flag for scheduling statistics when disable is specified.
2013-09-09Fix incorrect values returned by integer_to_binary/2Juan Jose Comellas
When integer_to_binary/2 receives 0 or a negative number as an argument with a base that is different from 10, it will return incorrect values (<<>> in the case of 0) or it will crash (with negative numbers). This commit fixes these problems and adds tests to cover these cases.
