* General business
We confirmed the calendar for upcoming meetings, the next meeting
is July 24th.
Andrew reminded attendees of the links to the procedures of the Austin Group,
and the three bodies now present in the etherpad.
Regarding news of Don Cragun, Andrew reported he had contacted Roger Martin,
but Roger has also not heard from Don recently. Roger will let us know
if he hears of any news.
* Carried Forward
Bug 1927: Add sponge utility
https://www.austingroupbugs.net/view.php?id=1927
[Action to Eric B] Start a 30-day request for comments on whether The Open
Group should sponsor the addition of this interface.
glibc realloc() behavior
[Action to Eric B] - respond to the thread and invite Alejandro to
open a bug against POSIX if we still need to address wording issues
Update 2025-06-26: discussion on mailing lists is still ongoing;
EricB or Alejandro will open a bug soon
* New Business
Bug 1930: Add flock(1) utility to manage locks from shell scripts
https://www.austingroupbugs.net/view.php?id=1930
Existing implementations create flock(2) locks, which are associated
with a file description. Since the standard does not have flock(2),
if we add the utility, we would specify it as creating the new
fcntl() file description based locks, not the old process-owned
fcntl() locks. It is assumed that any implementation that has
flock(2) and also the new fcntl() file description based locks would
have them interact.
Action: Eric B to ask The Open Group if they will sponsor this.
Bug 1931: Behavior of scandir() when no entries are selected
https://www.austingroupbugs.net/view.php?id=1931
Accepted-as-marked, resolved, tc1-2024 tag
Change lines 21757-21763 from:
The scandir( ) function shall scan the directory dir, calling
the function referenced by sel on each directory entry. Entries
for which the function referenced by sel returns non-zero shall
be stored in strings allocated as if by a call to malloc( ),
and sorted as if by a call to qsort( ) with the comparison
function compar, except that compar need not provide total
ordering. The strings are collected in array namelist which
shall be allocated as if by a call to malloc( ). If sel is a
null pointer, all entries shall be selected. If the comparison
function compar does not provide total ordering, the order in
which the directory entries are stored is unspecified.
to:
The scandir( ) function shall scan the directory dir, calling
the function referenced by sel on each directory entry. Entries
for which the function referenced by sel returns non-zero shall
be stored in dirent structures allocated as if by a call to
malloc( ), and sorted as if by a call to qsort( ) with the
comparison function compar, except that compar need not provide
total ordering. The dirent structures are collected in the array
pointed to by namelist which shall be allocated as if by a call
to malloc( ) if at least one entry is selected by sel; if no
entries are selected, it is unspecified whether the array is
allocated as if by a call to malloc or the value pointed to by
namelist is set to a null pointer. If sel is a null pointer,
all entries shall be selected. If the comparison function compar
does not provide total ordering, the order in which the directory
entries are stored is unspecified.
Change the example lines 21799-21815 to:
#include <dirent.h>
#include <stdio.h>
#include <stdlib.h>
...
struct dirent **files;
int i,n;
n = scandir(".", &files, NULL, alphasort);
if (n < 0)
perror("scandir");
else {
for (i = 0; i < n; i++) {
printf("%s\n", files[i]->d_name);
free(files[i]);
}
}
if (files)
free(files);
...
Page 615 lines 21826-21828, change:
For functions that allocate memory as if by malloc( ), the
application should release such memory when it is no longer
required by a call to free( ). For scandir( ), this is namelist
(including all of the individual strings in namelist).
to:

Bug 1932: termios: should cfsetospeed(B0) trigger SIGHUP?
https://www.austingroupbugs.net/view.php?id=1932
Accepted-as-marked, resolved, tc1-2024 tag
On page 209 line 7522 section 11.2.4 Control Modes, change:
For pseudo-terminals, the input and output baud rates set in
the termios structure need not affect the speed of data
transmission through the terminal interface.
to:
For pseudo-terminals, the input and output baud rates set in
the termios structure need not affect the speed of data
transmission through the terminal interface and setting the
output baud rate to B0 need not cause a modem disconnect.
Bug 1933: make: example 7 contains text for two separate topics
https://www.austingroupbugs.net/view.php?id=1933 OPEN
We will start on this item next time.
* Next Steps
