Draft Status
---------------
Andrew noted that Keld Simonsen had raised a request to wait until the
completion of the ISO ballot before publication of TC2. No decision was
reached on the matter, and we'll leave it open for the moment. As far
as we know its just an up down ballot. We need
to determine if we get can get a timely response from ISO, the ballot is
due to close on April 14. Perhaps our ISO reps can report back on
what the letter ballot is (Andrew says he does not have sight of these
items at the ISO level).
Andrew reported that the TC2 document itself
is ready to publish now and is just awaiting an ISBN number from IEEE.
The editors will prepare the merged document incorporating TC2 during
the month of March.
No comments had been received on the draft Change History

Defect Report Processing
-------------------------
The group picked up on the latest batch of defect reports,
which are available at the following URL:
http://www.opengroup.org/austin/aardvark/latest/
XCU ERN 15 STDOUT format of the locale utility Accept as marked
The review group agreed that the standard is unclear about
LANG when it has no value. This should be raised as an interpretation
and forwarded to the sponsor for consideration in a future revision.
Proposed changes for a future revision are as follows:
Insert a new 1st para in STDOUT
The LANG variable shall be written first using the format
"LANG=%s\n", <value>
If LANG is not set or is an empty string the value is the
empty string.
Change the existing first para
from:
If locale is invoked without any options or operands, the names
and values of the LANG and LC_* environment variables described
in this volume of IEEE Std 1003.1-2001 shall be written to the
standard output, one variable per line, with LANG first, and
each line using the following format. Only those variables set
in the environment and not overridden by LC_ALL shall be written
using this format:

XCU ERN 16 cp -if vs cp -fi REJECT
The review group agreed that the standard is what it says.
The words "in effect" means appears on the command line,
there is no difference between cp -fi and cp -if, the details
are in step 3 of the actions to be taken for each
source_file in the DESCRIPTION section of the cp
manual page.
XCU ERN 17 removal of references to ctime in pax man page ACCEPT
The review group agreed that this was an editorial matter,
and that the references to the now removed ctime field,
which is removed in TC2, should be removed as noted
for consistency.
(note 2001 edition numbers below)
Page 703,722
On line 27120 change:
atime, ctime, and mtime extended header records
to:
atime and mtime extended header records
On line 27905 change:
-o listopt='(name)s\n%(ctime)T\n%T'
to:
-o listopt='(name)s\n%(atime)T\n%T'
(the editors should also check the rationale section for pax)
XSH ERN 33 ftruncate errors ACCEPT
The review group agreed with the defect report. It should be forwarded
to the sponsor as an interpretation request.
Proposed changes for a future revision (line nos 2001 edition):
1. Remove the XSI shading from the EFBIG error on lines 15060-15061.
2. Delete lines 15065-15066:
[EINVAL] The fildes argument references a file that was opened
without write permission.
3. Delete line 15067:
[EROFS] The named file resides on a read-only file system.
4. Add after line 15067:
The ftruncate() function may fail if:
[EINVAL] The fildes argument references a regular file and the
length argument is greater than the current size of the
file, and the implementation does not support the XSI
option.
XSH ERN 34 fopen/tmpfile umask ACCEPT
The review group agreed that this should be filed as an interpretation
request as suggested in the request.
"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."
In a future revision make the following changes:
Add to the existing CX shaded block in fopen() which states:
"If mode is w, wb, a, ab, w+, wb+, w+b, a+, ab+, or a+b, and the file
did not previously exist, upon successful completion, the fopen()
function shall mark for update the st_atime, st_ctime, and st_mtime
fields of the file and the st_ctime and st_mtime fields of the parent
directory."
Add (also CX shaded):
"If mode is w, wb, a, ab, w+, wb+, w+b, a+, ab+, or a+b, and the
file did not previously exist, the fopen() function shall create a
file as if it called the creat() function with a value appropriate
for the /path/ argument interpreted from /filename/ and a value of
S_IRUSR|S_IWUSR|S_IRGRP|S_IWGRP|S_IROTH|S_IWOTH for the mode argument"
A corresponding change is then also needed to tmpfile() to change
from:
"The file is opened as in fopen() for update (w+)"
to:
"The file is opened as in fopen() for update (w+), except implementations may restrict the permissions, either by clearing
the file mode bits or setting them to the value S_IRUSR|S_IWUSR"
Next Steps
-----------
Andrew will update the aardvark reports with the latest inbound
defect reports.
We still need to discuss what the strategy is post TC2.
There are a number of open action items outstanding:
1. Don Cragun Pathname Resolution proposal
2. Larry Dwyer system() and threads
3. Joerg Schilling wording for XCU ERN 1 pax
The next teleconference call is scheduled for March 11 2004
