If the file was larger than the OS send buffer the call would fail before this patch.

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: Make copy_literals more fail safeSverker Eriksson
* Same process must do enable-disable. * System process will force it and never get 'aborted'
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.

2016-01-11erts: 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

2015-12-21Do not allow aux work on dirty schedulersSteve Vinoski
The nature of aux work is such that dirty schedulers should not attempt to perform it. Modify the code to ensure that dirty schedulers avoid aux work. Also fix an incorrect assumption about the size of a Uint in the ErtsDirtySchedId type.
2015-12-20efile_drv: logic error in compressed file writeMikael Pettersson
Compiling OTP 18.2.1 with gcc-5.3 shows the following warning: drivers/common/efile_drv.c:1538:23: warning: logical not is only applied to the left hand side of comparison [-Wlogical-not-parentheses] The code in question is: if (! (status = erts_gzwrite((ErtsGzFile)d->fd, iov[i].iov_base, iov[i].iov_len)) == iov[i].iov_len) { d->errInfo.posix_errno = d->errInfo.os_errno = errno; /* XXX Correct? */ break; } If we hoist the assignment out of the if for clarity, it becomes: status = erts_gzwrite(..., iov[i].iov_len); if (! status == iov[i].iov_len) { ...; break; } iov_len is > 0 here, and status will equal iov_len if erts_gzwrite succeeded, but will be less than iov_len if an error occurred. "! status" is 0 or 1, which can only equal iov_len if iov_len is 1 and erts_gzwrite detected an error and returned 0. The effect of this mistake is that any error when iov_len >= 2 will skip the conditional code and break statement. In particular, partial writes (0 < status && status < iov_len) will not be flagged as errors. All releases since OTP R8B-0 are affected. The variable "status" is really a boolean, which is to be set to zero on error. The fix is to set status to 1 if erts_gzwrite() returned iov_len and 0 otherwise, and to change the condition to "if (! status) ...". I'm also hoisting the assignment out of the condition since it obscures the code while providing not benefit (the condition in a while or for loop would be a different matter).
