2013-12-02Compile in_heapfrag() only in debug modeAnthony Ramine
2013-12-02erts: Remove unused file winsock_func.hSverker Eriksson
2013-12-02Silence a warning in erl_poll about an empty loop bodyAnthony Ramine
The warning is: sys/common/erl_poll.c:2513:72: warning: for loop has empty body [-Wempty-body] for (prev_ps = pollsets; ps != prev_ps->next; prev_ps = prev_ps->next);
2013-12-02Fix erts_check_off_heap2 assertionAnthony Ramine
The test needs to be false to fail, not true. This was noticed with the following warning, where marking erl_assert_error as non-returning didn't help: beam/erl_gc.c:2772:2: warning: variable 'refc' is used uninitialized whenever switch default is taken [-Wsometimes-uninitialized] default: ^~~~~~~ beam/erl_gc.c:2775:26: note: uninitialized use occurs here ERTS_CHK_OFFHEAP_ASSERT(refc >= 1); ^~~~ beam/erl_gc.c:2738:11: note: expanded from macro 'ERTS_CHK_OFFHEAP_ASSERT' if (!(EXP)) \ ^ beam/erl_gc.c:2759:18: note: initialize the variable 'refc' to silence this warning erts_aint_t refc; ^ = 0
2013-12-02Properly mark erl_assert_error as non-returningAnthony Ramine
2013-12-02Remove uninitialized use of new_crr in erl_alloc_utilAnthony Ramine
When the offending code is reached, new_crr is either uninitalized or have been set to NULL. This patch removes the following warning: beam/erl_alloc_util.c:3510:6: warning: variable 'new_crr' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized] if (!(flags & CFLG_FORCE_MSEG)) { ^~~~~~~~~~~~~~~~~~~~~~~~~~ beam/erl_alloc_util.c:3567:23: note: uninitialized use occurs here DEBUG_SAVE_ALIGNMENT(new_crr); ^~~~~~~ beam/erl_alloc_util.c:674:51: note: expanded from macro 'DEBUG_SAVE_ALIGNMENT' UWord algnmnt__ = sizeof(Unit_t) - (((UWord) (C)) % sizeof(Unit_t));\ ^ beam/erl_alloc_util.c:3510:2: note: remove the 'if' if its condition is always true if (!(flags & CFLG_FORCE_MSEG)) { ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ beam/erl_alloc_util.c:3438:23: note: initialize the variable 'new_crr' to silence this warning Carrier_t *new_crr, *old_crr; ^ = NULL

2013-11-27erts: Fix invalid read when appending binaries during call traceSverker Eriksson
Found by valgrind. Probably safe on opt-VM due to CHICKEN_PAD.
2013-11-26erts: Optimize comparison for bitstrings with byte aligned startSverker Eriksson
2013-11-26erts: Fix invalid read in bitstring comparisonSverker Eriksson
Valgrind complained that erts_cmp_bits sometimes read one byte too much from bitstrings. The byte was never used and the invalid read is safe in opt-VM due to padding in binary allocation (CHICKED_PAD).

2013-11-15Add sync option to file:open/2Joseph Blomstedt
The sync option adds the POSIX O_SYNC flag to the open system call on platforms that support the flag or its equivalent, e.g., FILE_FLAG_WRITE_THROUGH on Windows. For platforms that don't support it, file:open/2 returns {error, enotsup} if the sync option is passed in. The semantics of O_SYNC are platform-specific. For example, not all platforms guarantee that all file metadata are written to the disk along with the file data when the flag is in effect. This issue is noted in the documentation this commit adds for the sync option. Add a test for the sync option. Note however that the underlying OS semantics for O_SYNC can't be tested automatically in any practical way, so the test assumes the OS does the right thing with the flag when present. For manual verification, dtruss on OS X and strace on Linux were both run against beam processes to watch calls to open(), and file:open/2 was called in Erlang shells to open files for writing, both with and without the sync option. Both the dtruss output and the strace output showed that the O_SYNC flag was present in the open() calls when sync was specified and was clear when sync was not specified.

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.

Replaced the +MMscmgc switch with the +MMscrfsd switch. The old switch didn't reflect what it controlled.
