2016-01-20Introduce time warp safe replacement for safe_fixed optionRickard Green
The new time warp safe option is safe_fixed_monotonic_time which gives erlang:monotonic_time(). The safe_fixed option was also slightly changed. It now gives erlang:timestamp() instead of erlang:now(). This has however not been documented, so it is considered a compatible change. The above effects both ets, and dets. This commit also include the bugfix OTP-13239 for dets:info(Tab, safe_fixed). The timestamp in the result returned by dets:info(Tab, safe_fixed) was unintentionally broken as a result of the time API rewrites in OTP 18.0.

New timestamp options for trace, sequential trace, and system profile: - monotonic_timestamp - strict_monotonic_timestamp

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).

2015-12-15Prevent down nodes going undetected in epmdAlexey Lebedeff
In the following (rare) case down node will be always registered in epmd: - client connects to epmd and sends ALIVE2 request - epmd reads this request and starts to process it - during that time client socket closes in such way that subsequent write(2) in epmd will result in error - at this point we have node that was registered in database, but as the connection struct has no 'keep' flag set, the do_read() closes connection and removes it from select fdset - and so there is no way for this node to be cleaned up later. We've seen several epmd instances in such state on our production systems. And while I'm not sure what was the exact sequence of events that leads to failed write(2), issue could be easily reproduced using SO_LINGER option for socket.
