Bug 0000721: Internal storage vs static storage OPEN http://austingroupbugs.net/view.php?id=721 This item is still open. * Current Business On the outstanding actions above we request all that have actions to take a look to see whether they can resolve any bugs that might be suitable for inclusion in TC2. Bug 0000375: Extend test/[...] conditionals: ==, <, >, -nt, -ot, -ef OPEN http://austingroupbugs.net/view.php?id=375 David has completed his action from the previous meeting. There have been some further comments received and he plans a further update. Geoff noted that the comments in bugnote 1945 should be taken into account for the update. ACTION: David A. Wheeler to make a further update on the proposal. Bug 0000770: Add support for .ONESHELL in make OPEN http://austingroupbugs.net/view.php?id=770 This item is still open with the action carried forward below from the previous meeting. ACTION:David A. Wheeler to propose a new set of changes that add .ONESHELL just as a per-rule feature, not global. Bug #772 New time zone conversion specifier character Rejected http://austingroupbugs.net/view.php?id=772 The group decided to reject this request based on Note: 0001905 and the fact that the requested feature does not have any current implementations. (bugnote 1905 text:) Timezone names of the requested form are already supported. As explained in XRAT A.8.3: TZ The quoted form of the timezone variable allows timezone names of the form UTC+1 (or any name that contains the character plus ('+'), the character minus ('-'), or digits), which may be appropriate for countries that do not have an official timezone name. It would be coded as +1, which would cause std to have a value of UTC+1 and dst a value of UTC+2, each with a length of 5 characters. Example: $ TZ="+3" date Tue Oct 15 12:53:11 UTC+04 2013 Bug #773 Summary: Add \+, \?, and \| to Basic Regular Expressions (BREs) OPEN http://austingroupbugs.net/view.php?id=773 The group agreed on the concept but feel there is a need to check into precedence, esp. \| with anchoring (^ and $). ACTION: David A. Wheeler to take action to review precedence on existing systems. Bug #774 Summary: Addition of a POSIX_VERSION shell variable OPEN http://austingroupbugs.net/view.php?id=774 The general consensus that this is a bad idea, and to reject. ACTION Don to do the actual reject update in Mantis, adding additional rationale. Bug #776 incorrect use of the term "symbolic constant" in several headers Rejected http://austingroupbugs.net/view.php?id=776 This item was rejected. The quoted bullet item from XBD 3.374 is preceded by introductory text which says "Unless stated otherwise, the following shall apply to every symbolic constant". It is entirely intentional that some headers define non-integer symbolic constants. The type stated in the header overrides the integer default from XBD 3.374. Bug #777 leading zeros in IPv6 address text forms Accepted as marked http://austingroupbugs.net/view.php?id=777 This item is tagged for TC2-2008 The group believe the standard already requires this behavior, but agree that it should be spelled out explicitly. Change: The preferred form is "x:x:x:x:x:x:x:x", where the ’x’ s are the hexadecimal values of the eight 16-bit pieces of the address. Leading zeros in individual fields can be omitted, but there shall be at least one numeral in every field. on P1125 L37792-37794 to: The preferred form is "x:x:x:x:x:x:x:x", where the ’x’ s are the hexadecimal values of the eight 16-bit pieces of the address. Leading zeros in individual fields can be omitted, but there shall be one to four hexadecimal digits in every field. Bug #779 Add "ignore case" flag to sed's "s": s/old/new/I Accepted as Marked http://austingroupbugs.net/view.php?id=779 This item is tagged for Issue 8 After line 106510, add: i Match the regular expression in a case-insensitive way. Add new para to APPLICATION USAGE after line 106550: Note that some implementations of sed also support an 'I' flag for the 's' command as an alias for the lower case 'i' flag.
