Aardvark Bug Reports

XSH ERN 204 regcomp OPEN
We need to investigate behaviors
Unless a test program is submitted this item will remain open.
XSH ERN 217 tcsetattr OPEN
XSH ERN 218 poll OPEN
XCU ERN 153 update (no change to current resolution)
Note Geoff had posted the changes to implement in version 7
in mail seq 10927 and we should hold those on file for merging
into the revision. Andrew has added a note to the aardvark report.
XCU ERN 163 update
s/full/role/; s/non matching/``non-matching''/
Andrew has applied the corrections to the aardvark report.
XCU ERN 164 dot Accept
XCU ERN 165 mv Accept
Send down the interpretations track.
The standard is clear, the standard is wrong , concerns
are being forwarded to the sponsor.
XCU ERN 166 mv Accept as marked below
Send down the interpretations track.
The standard is ambiguous, no conformance distinctions can be
made about different implementations , concerns
are being forwarded to the sponsor.
At line 25398, insert a new step 2:
2. If the source_file operand and destination path name the same
existing file, then the destination path shall not be removed, and one of
the following shall occur:
a. No change is made to source_file, no error occurs, and no
diagnostic is issued.
b. No change is made to source_file, a diagnostic is issued to
standard identifying the two names, and the exit status is affected.
c. If the source_file operand and destination path name distinct
directory entries, then the source_file operand is removed, no error
occurs, and no diagnostic is issued.
The mv utility shall do nothing more with
the current source_file, and go on to any remaining source_files.
Renumber the existing steps 2-6 into 3-7.
At line 25500, add a new paragraph to Application Usage:
The specification ensures that 'mv a a' will not alter the contents
of file 'a', and allows the implementation to issue an error that
a file cannot be moved onto itself. Likewise, when 'a' and 'b'
are hard links to the same file, 'mv a b' will not alter 'b', but
if a diagnostic is not issued, then it is unspecified whether 'a'
is left untouched (as it would be by the rename() function) or
unlinked (reducing the link count of 'b').
XCU ERN 57 mv Accept as marked below
Send down the interpretations track.
The standard is clear, concerns
are being forwarded to the sponsor.
After XCU page 655 line 25410 append this:
If the destination path exists and was created by a previous step it is
unspecified whether this will treated as an error or the
destination
path will be overwritten.
Change XCU page 268 line 10474 from this:
a. If dest_file exists, the following steps shall be taken:
to this:
a. The behavior is unspecified if dest_file exists and was
written by a previous step. Otherwise, if dest_file exists, the
following steps shall be taken:
Action: Andrew to send further rdvks down the interpretations track.
