Bug 1016: race condition with set -C Accepted as Marked
http://austingroupbugs.net/view.php?id=1016
An interpretation is required
This item is tagged for Issue 8
Interpretation response:
The standard states the requirements for redirection with '>' when
set -C is in effect, and conforming implementations must conform
to this. However, concerns have been raised about this which are
being referred to the sponsor.
Rationale:
Historical shells just called stat() to check if a regular file
existed and then called creat(). The operation thus involved a race
condition which meant that it could not be used for reliable creation
of lock files or unique (often temporary) files. Modern shell
implementations are instead using open() with the O_CREAT and O_EXCL
flags set as one step in a multi-step process, although this makes
their behavior differ from the behavior required by the standard
in certain respects.
Notes to the Editor (not part of this interpretation):
Make the changes in Note: 0003485, choosing between option 1 and
option 2 during work on the Issue 8 drafts.
Bug 0001022: error indicator for encoding errors in fgetwc(3) OPEN
http://austingroupbugs.net/view.php?id=1022
Action: request Nick to raise with the C committee
Bug 1023: Behaviour of ls -R without -a under presence of directories beginning
with a dot Accepted as Marked
http://austingroupbugs.net/view.php?id=1023
An interpretation is required.
This item is tagged for Issue 8
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:
It seems that all implementations of ls, but one, have excluded
hidden directories when using ls -R without -A and without -a. The
standard developers believe that this is the correct or intended
behavior. However, the standard did not clearly specify this behavior.
Notes to the Editor (not part of this interpretation):
Change:
Recursively list subdirectories encountered.
to:
Recursively list subdirectories encountered. Subdirectories
with filenames beginning with a <period> ('.') shall be recursively
listed if and only if the subdirectory name was included in the
filenames listed for the containing directory.
Bug 1024: chmod() should be allowed to ignore S_ISVTX OPEN
http://austingroupbugs.net/view.php?id=1024
We started on this item and will continue next time.
