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 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 0000789: Add set -o pipefail OPEN http://austingroupbugs.net/view.php?id=789 * Current Business 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. Andrew has now completed his action to request Donn Terry to check the resolution to Bug 226 - updates on the awk grammar. Bug 0000835: file descriptor allocation by pipe() unclear Accepted http://austingroupbugs.net/view.php?id=835 This item is tagged for TC2-2008 It was noted that in Issue 8, we should move this new section 2.13 closer to section 2.5. Bug 0000834: definition of file mode Accepted as Marked http://austingroupbugs.net/view.php?id=834 It was discussed whether this bug duplicates 732, however it was decided that it is a subset applicable to TC2 as editorial while 732 is a proposal for a new interface in Issue 8. This item is tagged for TC2-2008 Change XBD 3.168 from An object containing the file mode bits and file type of a file. to An object containing the file mode bits and some information about the file type of a file. Bug 0000833: SOCK_* flags in getaddrinfo hints->ai_socktype http://austingroupbugs.net/view.php?id=833 During the call, it was determined that the intent of 0000411 is that the two new SOCK_ flags are for use only when opening an fd (socket(), socketpair(), accept4()). An application can recover the current state of the flags via fcntl() F_GETFL and F_GETFD - but that state may be different than what was originally passed in when opening the socket if intervening fcntl() F_SETFL or F_SETFD have been used. Therefore, the flags should NOT be used in other interfaces that are referring to a socket type. Thus, getaddrinfo() should fail with EAI_SOCKTYPE if the caller includes either flag in the hints, and getsockopt() with SO_TYPE should return the type with the flags masked out. In the original poster's description, only the second code snippet is valid. This item is left open, as we need proposed wording to build upon requirements added by bug 411.
