Minutes of the 12th September 2022 Teleconference Austin-1254 Page 1 of 1 Submitted by Andrew Josey, The Open Group. 16th September 2022 Attendees: Don Cragun, IEEE PASC OR Mark Ziegast, SHware Systems Dev. Nick Stoughton, Logitech/USENIX, ISO/IEC JTC 1/SC 22 OR Eric Ackermann, HPI, University of Potsdam Geoff Clare, The Open Group Apologies: Eric Blake Andrew Josey Tom Thompson * General news This was a call dedicated to general bugs. Don took an action to submit a Mantis bug based on austin-group-l mail sequence #34789 about stty. * Current Business Bug 1122: POSIX should include gettext() and friends OPEN and https://posix.rhansen.org/p/gettext_draft Also https://austingroupbugs.net/file_download.php?file_id=64&type=bug Geoff has uploaded a new PDF and has applied the changes from it in the Issue8NewAPIs branch in gitlab, except for the global NLSPATH change. AJ and Geoff took an action to start work on preparing a company review draft within The Open Group for new APIs. Bug 1560: clarify wording of command substitution https://austingroupbugs.net/view.php?id=1560 Leave this and related bugs 1561 and 1564 open awaiting reviews/discussion. Bug 1273: glob()'s GLOB_ERR/errfunc and non-directory files OPEN https://austingroupbugs.net/view.php?id=1273 We will leave this open awaiting feedback. Bug 768: add "fd-private" POSIX locks to spec OPEN https://austingroupbugs.net/view.php?id=768 Linux has now had OFD locks for several years, and more code in the wild is starting to use it - so we have existing practice (see note 2508) https://www.gnu.org/software/libc/manual/html_mono/libc.html#Open-File-Description-Locks Starting point of resolution at https://posix.rhansen.org/p/bug768 AI to EricB - take the GNU documentation and turn it into a desired action Bug 739: CX requirements for strftime seem to conflict with ISO C OPEN https://austingroupbugs.net/view.php?id=739 Nick completed his action to liaise with the C committee on this issue. C23 is about to go to ballot, so the way to raise the issue would be as a ballot comment. This could be done either as a UK or US national body comment. Andrew confirmed with the UK C Panel that we can submit comments. Bug 728: Restrictions on signal handlers are both excessive and insufficient OPEN https://austingroupbugs.net/view.php?id=728 The alignment with C17 changes the requirements in this area. There is still no allowance for accessing const objects or string literals, so that is something we could consider adding as an extension to C. Or we could raise the issue with the C committee if we want to stay in sync with the C standard. Suggestion: raise it as a C23 ballot comment. Depending on the answer, we could implement what they plan to do, or diverge (or leave things as they are). AI Nick and Geoff: File ballot comments on C23 (through the US and/or UK national bodies to WG14). Bug 708: Make mblen, mbtowc, and wctomb thread-safe for alignment with C11 OPEN https://austingroupbugs.net/view.php?id=708 This was discussed with WG14: https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2148.htm#dr_498 DR 498 (URL above) seems to have an agreed wording change from April 2017, but it has not been applied. Nick asked the WG14 convenor what happened to that DR. It appears the item was discussed but in the end the C committee could not agree an acceptable change, and no alternate proposal was available. We will need to accept the C wording for now. Bug 700: Clarify strtoul's behaviour on strings representing negative numbers OPEN https://austingroupbugs.net/view.php?id=700 AI: Nick and Geoff to work together on a C23 ballot comment (against N3047 7.24.1.7 para 5). Bug 689: Possibly unintended allowance for stdio deadlock OPEN https://austingroupbugs.net/view.php?id=689 Change needs to be coordinated with C23. AI: Nick and Geoff to work together on a C23 ballot comment (against N3047 7.23.3 para 3). Bug 618: require isatty and friends to set errno on failure OPEN https://austingroupbugs.net/view.php?id=618 Action item to EricB: email to various lists to collect results for sample program (see bug 503 comment 1005 for starting point) for current errno behavior on various OS Bug 513: Add pattern rules (metarules) to make OPEN https://austingroupbugs.net/view.php?id=513 This was discussed and a note added to the bug but left open. We are leaning towards rejecting based on irreconcilable differences between existing implementations. However, the bug is being left open for now in case anyone wants to try to come up with a common subset of functionality that would be worth adding to the standard. Bug 512: Add macro functions to make Rejected https://austingroupbugs.net/view.php?id=512 This was discussed in the September 12th, 2022 teleconference. Although many of these functions are useful, the fact that they have been around so long and have not been duplicated in the BSD and SunPro make implementations implies that there hasn't been much user demand to add them. Therefore, this bug is rejected. Bug 465: is the list of special built-ins exhaustive (is "local" special)? OPEN https://austingroupbugs.net/view.php?id=465 We started on bug 465 and will continue on Thurs.
