* 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.
