This was discussed and Jim took an action to provide further information. +Bug 0000598: OH shading and new interfaces OPEN http://austingroupbugs.net/view.php?id=598 Eric has an action to propose a new solution with self-contained headers. +Bug 0000517: EBNF support OPEN http://austingroupbugs.net/view.php?id=517 Action on Joerg to look at this. +Bug 0000633: SIGEV_THREAD delivery renders many signal interfaces unsafe OPEN http://austingroupbugs.net/view.php?id=633 We noted that feedback has settled down on the mailing list, and will discuss next session. +Bug 0000657: Conditions under which fmemopen() write a NUL to the buffer are insufficiently specified OPEN http://austingroupbugs.net/view.php?id=657 Eric has an action to propose wording to clarify the behavior for fmemopen(), and also to contact the glibc developers to get their feedback. +Bug 0000658: Undefined/unspecified behavior clauses in description of open have race conditions OPEN http://austingroupbugs.net/view.php?id=658 It was noted that there is some overlap with changes in TC1. 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. Jim to report back on whether pthread_cancelstate() is async-signal-safe on Solaris. Andrew to ask HP whether pthread_cancelstate() is async-signal-safe on HP-UX. Bug 622 left open pending resolution of 615. http://austingroupbugs.net/view.php?id=622 Bug 0000672: Necessary step(s) to synchronize filename operations on disk OPEN http://austingroupbugs.net/view.php?id=672 Geoff has a new proposed resolution in note 1618. Decided to solicit input from FS developers. Eric to go to Linux, Mark to AIX and Jim to Solaris. * Current Business Nick reported that he was still working on actions for bugs 700 and 701 Bug 0000696: either NAME_MAX shouldn't be optional, or readdir_r() needs clarification http://austingroupbugs.net/view.php?id=696 OPEN Don reported that he is still working on his action for this item. (to propose wording) Bug 0000697: Adding of a getdirentries() function OPEN http://austingroupbugs.net/view.php?id=697 Andrew has completed his action to pass this to The Open Group Base WG for attention. Bug 0000693: Clarification on export status of make variables Accepted As Marked http://austingroupbugs.net/view.php?id=693 This item is tagged for TC2-2008. An interpretation is required. Interpretation response: The standard does not speak to this issue, and as such no conformance distinction can be made between alternative implementations based on this. This is being referred to the sponsor. Rationale: None. Notes to the Editor (not part of this interpretation): At page 2942 line 97319 after: Before the makefile(s) are read, all of the make utility command line macro definitions (except the MAKEFLAGS macro or the SHELL macro) shall be added to the environment of make. Other implementation-defined variables may also be added to the environment of make. append: Macros defined by the MAKEFLAGS environment variable and macros defined in the makefile(s) shall not be added to the environment of make if they are not already in its environment. With the exception of SHELL (see below), it is unspecified whether macros defined in these ways update the value of an environment variable that already exists in the environment of make. At page 2953 line 97788 change: The environment is the same as the environment to make except that MAKEFLAGS and macros defined on the make command line are added. to: The environment is the same as the environment to make except that MAKEFLAGS and macros defined on the make command line are added, and except that macros defined by the MAKEFLAGS environment variable and macros defined in the makefile(s) may update the value of an existing environment variable (other than SHELL). At page 2954 line 97849 change FUTURE DIRECTIONS from: None. to: Some implementations of make include an "export" directive to add specified make variables to the environment. This may be considered for standardization in a future revision. Bug 0000704: Clarify interoperability of wordfree(3) Accepted as Marked http://austingroupbugs.net/view.php?id=704 This item is tagged for TC2-2008. An interpretation is required. Interpretation response The standard is unclear on this issue, and no conformance distinction can be made between alternative implementations based on this. This is being referred to the sponsor. Rationale: The standard is clear that wordfree() can be called after any wordexp() call, not just successful ones, and also states that pwordexp−>we_wordc and pwordexp−>we_wordv shall not be modified on success. (Lines 72184-72185 do not contain the word "successful"). Notes to the Editor (not part of this interpretation): On page 2281 line 72243, change: In other cases, they shall not be modified. to: In other error cases, if the WRDE_APPEND flag was specified, pwordexp->we_wordc and pwordexp->we_wordv shall not be modified. Add after page 2281 line 72230: The results are unspecified if WRDE_APPEND and WRDE_REUSE are both specified.
