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 #847: open(O_CREAT), directories, and EISDIR Accepted as Marked
http://www.austingroupbugs.net/view.php?id=847
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:
The standard does not specify the behavior when open() is called
with O_CREAT|O_RDONLY (or O_CREAT|O_SEARCH) on an existing directory.
Additionally, some systems want to allow creation of directories
using the open() function. This should be an allowed, but not
required, extension.
Notes to the Editor (not part of this interpretation):
On page 238 line 7885 change:
O_DIRECTORY Fail if not a directory.
to:
O_DIRECTORY Fail if file is a non-directory file.
On page 1391 at line 45975 (open() description, O_CREAT), change:
Otherwise, the file shall be created
to:
Otherwise, if O_DIRECTORY is not set the file shall be created as a regular file
On page 1393 after line 46051 (open() description), insert a new paragraph:
If O_CREAT and O_DIRECTORY are set and the requested access
mode is neither O_WRONLY nor O_RDWR, the result is unspecified.
On page 1394 at line 46098 (open() errors, EISDIR), change:
The named file is a directory and oflag includes O_WRONLY or O_RDWR.
to:
The named file is a directory and oflag includes O_WRONLY or
O_RDWR, or includes O_CREAT without O_DIRECTORY.
Bug #848: make defaults CFLAGS to -O, but c99 requires a level Accepted as Marked
http://www.austingroupbugs.net/view.php?id=848
This item is tagged for TC2-2008
An interpretation is required.
Interpretation response:
The standard states that by default make shall achieve results that
are the same as CFLAGS=-O, and conforming implementations must
conform to this. However, concerns have been raised about this which
are being referred to the sponsor.
Rationale:
The specification for the c99 utility does not support -O without
an option-argument. In addition, if a subsequent argument is provided,
the argument will be (erroneously) interpreted as an optimization
level.
Notes to the Editor (not part of this interpretation):
On page 2945 line 97465 change:
CFLAGS=-O
to:
CFLAGS=-O 1
On page 2949 line 97621 change:
c99 −c −O $*.c
to:
c99 −c −O 1 $*.c
On page 2949 line 97624 change:
c99 −c −O $<
to:
c99 −c −O 1 $<
Bug #849: Normative and informative text on return value of pthread_create() are incompatible Accepted as Marked
http://www.austingroupbugs.net/view.php?id=849
This item is tagged for TC2-2008.
On Page: 1602 Line: 51480 Section: pthread_create()
In the APPLICATION USAGE section, change from:
through the return value of the pthread_create() function
to:
through the thread argument of the pthread_create() function
Bug #850: Standardize MAP_ANON OPEN
http://www.austingroupbugs.net/view.php?id=850
This was discussed during the call and a proposed response has been added
to the bug report, as bugnote 2281.
This will be continued on the next call.
