Minutes of the 11 April 2013 Teleconference Austin-604 Page 1 of 1 Submitted by Andrew Josey, The Open Group. 12th April 2013 Attendees Don Cragun, PASC OR Andrew Josey, The Open Group Eric Blake, Red Hat Nick Stoughton, USENIX, ISO/IEC OR Jim Pugsley, Oracle Mark Brown, IBM, TOG OR Joerg Schilling, Fraunhofer Society Richard Hansen, BBN Geoff Clare, The Open Group * General News We are still targeting the merged 2013 edition document to be published with IEEE on 19 April 2013. Andrew has a request into the ISO secretariat on their publication schedule. Andrew had announced a preview of the html edition during the week. A number of cosmetic presentation changes have been made so far based on feedback received. With the publication of the merged document we will be closing bugs in the Mantis bug tracker, now that they have been applied . This will trigger a number of emails in the system. There are 280 bugs with the tc1-2008 tag. The bugs can be closed in a small number of operations, by selecting them in a filtered list, clicking "Select All" at the bottom left and then select "Close" from the drop-down and click OK. We agreed that this will happen on April 16th at 8am Austin time. Mantis will be unavailable for a short time while the changes are made. Andrew will post a notice before and after the downtime. Andrew will also post a list of the bugs. * Old Business +Bug 0000561: NUL-termination of sun_path in Unix sockets OPEN http://austingroupbugs.net/view.php?id=561 Eric has an action to update the proposal. +Bug 0000573: Please add '+' to the portable filename character set OPEN http://austingroupbugs.net/view.php?id=573 Joerg has an action to prepare a proposed change. +Bug 0000592: consistent use of struct timespec OPEN http://austingroupbugs.net/view.php?id=592 This item needs further investigation of existing implementations. Mark reported that AIX does not have a problem with this. Jim notes he is still looking at this. +Bug 0000598: OH shading and new interfaces OPEN http://austingroupbugs.net/view.php?id=598 Eric has an action to propose a new solution with self-contained headers. Bug 0000576: No format specifiers for several types OPEN http://austingroupbugs.net/view.php?id=576 Bug 0000599: Reserved "no thread" value for pthread_t A/M Issue 8 Bug 0000517: EBNF support OPEN http://austingroupbugs.net/view.php?id=517 It was agreed that we need Joerg's input on this item and have left it open for now. Andrew took an action on the 12 September call to notify Joerg (completed after the meeting). * Current Business Bug 0000633: SIGEV_THREAD delivery renders many signal interfaces unsafe OPEN http://austingroupbugs.net/view.php?id=633 This item was again left open pending further feedback. Bug 0000657: Conditions under which fmemopen() write a NUL to the buffer are insufficiently specified OPEN http://austingroupbugs.net/view.php?id=657 Eric has an action to propose wording to clarify the behavior for fmemopen(), and also to contact the glibc developers to get their feedback. Bug 0000656: Clearly allow or forbid thread-local storage for "static" buffers OPEN http://austingroupbugs.net/view.php?id=656 Don has an action to propose wording changes to all of the same places that bug 75 modified. Bug 0000654: unclear behavior of in-line variable assignments preceding functions, special built-ins OPEN http://austingroupbugs.net/view.php?id=654 Richard has volunteered to take an action to draft some words. Bug 0000658: Undefined/unspecified behavior clauses in description of open have race conditions OPEN http://austingroupbugs.net/view.php?id=658 It was noted that there is some overlap with changes in TC1. Eric took an action to update the proposal to resolve the overlaps appropriately. We will pick up with this one next time. A reminder for next week is to look at bug 573 (if Joerg has completed his action) Bug 0000663: Specification of str[n]casecmp is ambiguous ReOPENed http://austingroupbugs.net/view.php?id=663 It was agreed to postpone discussion of this item until next week as Mark needs to followup with his contact who has not been available this week. Bug 0000675: fcntl(fd, F_SETOWN, pid) error returns Accepted as Marked http://austingroupbugs.net/view.php?id=675 This item is tagged for TC2-2008 An interpretation is required. 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: Known existing implementations use ESRCH for this error. Notes to the Editor (not part of this interpretation): (Using page and line numbers from TC1-d3): At page 816 after line 27394 add: [ESRCH] The cmd argument is F_SETOWN and no process or process group can be found corresponding to that specified by pid. At page 817 after line 27398 add: [EINVAL] The cmd argument is F_SETOWN and the value of the argument is not valid as a process or process group identifier. Bug 0000669: mkdtemp/mkstemp handling of template with more than 6 'X's should be clarified Accepted as Marked http://austingroupbugs.net/view.php?id=669 This item is tagged for TC2-2008 An interpretation is required. 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: None. Notes to the Editor (not part of this interpretation): After applying the TC1 edits, change: The string provided in template shall be a pathname ending with six trailing 'X's. The mkdtemp() function shall replace each 'X' with a character from the portable filename character set. to: The application shall ensure that the string provided in template is a pathname ending with at least six trailing 'X's. The mkdtemp() function shall replace six or more 'X's at the end of the pathname with the same number of characters from the portable filename character set. At line 42430, after applying the TC1 edits, change: The string in template should look like a pathname with six trailing 'X's; mkstemp() replaces each 'X' with a character from the portable filename character set. to: The application shall ensure that the string provided in template is a pathname ending with at least six trailing 'X's. The mkstemp() function shall replace six or more 'X's at the end of the pathname with the same number of characters from the portable filename character set. At line 42476 in the APPLICATION USAGE section change: The mkdtemp() and mkstemp() functions need not check to determine whether the filename part of template exceeds the maximum allowable filename length. to: Portable applications should pass exactly six trailing 'X's in the template and no more; implementations may treat any additional trailing 'X's as either a fixed or replaceable part of the template. To be sure of only passing six, a fixed string of at least one non-'X' character should precede the six 'X's. Since 'X' is in the portable filename character set, some of the replacement characters can be 'X's, leaving part (or even all) of the template effectively unchanged. Bug 0000670: references to "time_" prefix should be "timer_" Accepted http://austingroupbugs.net/view.php?id=670 This item is tagged for TC2-2008 Bug 0000671: aio_fsync() EBADF and "open for writing" Accepted as Marked http://austingroupbugs.net/view.php?id=671 This item is tagged for TC2-2008 An interpretation is required. Interpretation response: The standard states that aio_fsync() shall fail on a read-only file descriptor, and conforming implementations must conform to this. However, concerns have been raised about this which are being referred to the sponsor. Rationale: The access mode of the file descriptor does not affect whether there are pending I/O operations on the underlying file. Notes to the Editor (not part of this interpretation): Make the changes in the Desired Action. Bug 0000672: Necessary step(s) to synchronize filename operations on disk OPEN http://austingroupbugs.net/view.php?id=672 Further discussion is needed, this item is left open until next week.
