Bug #684 posix_fallocate() should be allowed to return ENOTSUP Accepted as Marked http://austingroupbugs.net/view.php?id=684 This item is tagged for Issue 8 An interpretation is required. The interpretation status has been reset back to pending. Interpretation response: The standard does not speak to this issue, and as such no conformance distinction can be made between alternative implementations based on this. This is being referred to the sponsor. Rationale: If a system conforms to the Advisory Information Option it must also provide a filesystem that will support that option (see XSH 2.1.5). However, such systems may also support other, non-conforming filesystems, and the standard currently requires an EINVAL error for these. ENOTSUP is preferred so that this error can be distinguished from the other EINVAL cases. Notes to the Editor (not part of this interpretation): On page 1425 line 47084 delete (from the EINVAL error): , or the underlying file system does not support this operation Add on page 1425 after line 47088 (to the "shall fail" errors): [ENOTSUP] The underlying file system does not support this operation. Add to APPLICATION USAGE (page 1426, after the sentence on 47096): Not all filesystems are capable of supporting posix_fallocate(), in which case the function will return ENOTSUP. However, if a system supports the option, there must be at least one filesystem that is capable of supporting this function and is available for use in conforming environments. pthread_kill discussion (based on mail seq austin-group-l:archive/latest/19899) pthread_kill() on a terminated but unjoined thread should behave equivalently to kill on a zombie process Action to Eric to file a bug Bug 0000747: Confusing erroneous text about address-of-array in pthread_once rationale Accepted http://austingroupbugs.net/view.php?id=747 This item is tagged for TC2-2008 Bug 0000748: pthread_mutexattr_setrobust() and thread termination cases Accepted http://austingroupbugs.net/view.php?id=748 This item is tagged for TC2-2008 Bug 0000749: pthread_cond_[timed]wait() immediate errors Accepted http://austingroupbugs.net/view.php?id=749 This item is tagged for TC2-2008 Minor grammar edits were made inline: "Except in the case of ... and" changed to "Except for ... and" Bug 0000750: Async list handling of SIGINT and SIGQUIT depends on job control Accepted http://austingroupbugs.net/view.php?id=750 This item is tagged for TC2-2008 Bug 0000751: Using trap to reset SIGINT/QUIT in an asynchronous subshell Accepted http://austingroupbugs.net/view.php?id=751 This item is tagged for TC2-2008 Bug 0000752: Problem with the order of entries in the sysconf() table Accepted http://austingroupbugs.net/view.php?id=752 This item is tagged for TC2-2008 Bug 0000753: duplocale example typo: '}' Accepted http://austingroupbugs.net/view.php?id=753 This item is tagged for TC2-2008 Bug #754 We will pick up on this next time.
