Minutes of the 3rd April 2014 Teleconference Austin-650 Page 1 of 1 Submitted by Andrew Josey, The Open Group. 5 April 2014 Attendees: Mark Ziegast, SHware Systems Nick Stoughton, USENIX, ISO/IEC JTC 1/SC 22 OR Andrew Josey, The Open Group Don Cragun, IEEE PASC OR Geoff Clare, The Open Group David Clissold, IBM Richard Hansen, BBN Joerg Schilling FOKUS Fraunhofer Mark Brown, Canonical Eric Blake, Red Hat Martin Rehak, Oracle, The Open Group OR Apologies: David Wheeler, IDA * General news On the issues forwarded (794/800) to the Base Working Group, Andrew is progressing this towards a conclusion with the Base WG. He will report back the status at next weeks call. On TC2 development, Andrew reported he has completed the initial processing of 173 bugs - and that he was now starting to work on an additional 26 bugs. There was some discussion about early access to working copies of the TC2 bugs, and it was agreed to try this out using a subversion repository. https://svn.opengroup.org/websvn/listing.php?repname=POSIX This is a readonly view. Access is role based - for now please contact Andrew if you need access. We will discuss write access on the next call. Andrew reported there was no progress on hearing back from the IEEE staff liaison on the matter of access to historical draft standards. Mark Ziegast accepted an action to examine Open bugs for suitable Action Items for TC2 that haven't been noted as Assigned, or have been non-responsive about completion. * Outstanding actions +Bug 0000251: Forbid newline, or even bytes 1 through 31 (inclusive), in filenames OPEN http://austingroupbugs.net/view.php?id=251 Don has an action to produce a proposal. +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 Jim had provided additional information in bugnote 1627.

Eric took an action to update the proposal to resolve the overlaps appropriately. +Bug 0000615: pthread_setcancelstate should be async-signal-safe OPEN http://austingroupbugs.net/view.php?id=615 We now have reports on AIX and Apple.

Decided to solicit input from FS developers. Eric to go to Linux, David to AIX and Jim to Solaris. Jim has completed his action (see bugnote 1691). Andrew should chase HP and Apple for input. +Bug 0000663: Specification of str[n]casecmp is ambiguous reopened http://austingroupbugs.net/view.php?id=663 Action on David to follow up with the IBM developers about the EBCDIC collation sequence. Bug 696 either NAME_MAX shouldn't be optional, or readdir_r() needs clarification http://www.austingroupbugs.net/view.php?id=696 Don has an action to propose a resolution. Bug 0000721: Internal storage vs static storage OPEN http://austingroupbugs.net/view.php?id=721 This item is still open. Bug 0000375: Extend test/[...] conditionals: ==, <, >, -nt, -ot, -ef OPEN http://austingroupbugs.net/view.php?id=375 This is still left open due to discussions pending on the reflector.

Bug #0000800: Add support for the recursive printf() format %r OPEN http://austingroupbugs.net/view.php?id=800 Joerg has an action to write a new proposal. Martin has also forwarded this to The Open Group Base Working group for their consideration. * Current Business Eric has an action on fnmatch() with FNM_PATHNAME whichis still open. Bug #811: precondition for mutex destruction unclear; example contradicts normative text OPEN http://www.austingroupbugs.net/view.php?id=811 We have left this item open pending further input from Dave Butenhof on supplying a new example. Bug #829 Change XSH/TC1/D5/0017 [74] removed the corresponding normative text Accepted http://austingroupbugs.net/view.php?id=829 This item is tagged for TC2-2008 Bug#830: not clear that dirname() is purely a string operation Accepted http://www.austingroupbugs.net/view.php?id=830 This item is tagged for TC2-2008. An interpretation is required. Interpretation response: The standard clearly states that basename() and dirname() can be used together to parse strings that are in the form of a pathname, and conforming implementations must conform to this. Rationale: There is no requirement that the strings processed by basename() and dirname() refer to existing pathnames. Notes to the Editor (not part of this interpretation): Make the changes suggested in the Desired Action. Bug #831: How to allocate memory for readdir_r is unclear. Dup of 696 http://www.austingroupbugs.net/view.php?id=831 This is a duplicate of 696 Bug #617: add ffsl() and ffsll() Accepted http://austingroupbugs.net/view.php?id=617 This item is tagged for Issue 8 Bug #226: Questions on awk grammar OPEN http://austingroupbugs.net/view.php?id=226 We looked again at this item. https://collaboration.opengroup.org/platform/single_unix_specification/protected/mailarch.php?soph=N&action=show&archive=austin-group-l&num=16591 Proposed comment text: The consensus is that the grammar should be changed to permit: awk '{print} {print}' and: awk '/foo/; {print}' To resolve this issue we need explicit text changing the grammar. Any input would be appreciated. If desired, the grammar can be modified to reject actionless BEGIN and END; although we are also fine with the current situation of a semantic check rejecting something the grammar allows. Regarding ';;' as a terminator, POSIX awk was based on nawk, which accepts this. The mawk and gawk implementations do not accept ';;', which we consider to be an implementation bug. Action to contact mawk and gawk maintainers to inquire whether ';;' bug will be addressed. Eric did this for gawk.
