Based on the date this bug was created, it appears to have been reported against rawhide during the development of a Fedora release that is no longer maintained. In order to refocus our efforts as a project we are flagging all of the open bugs for releases which are no longer maintained. If this bug remains in NEEDINFO thirty (30) days from now, we will automatically close it. If you can reproduce this bug in a maintained Fedora version (7, 8, or rawhide), please change this bug to the respective version and change the status to ASSIGNED. (If you're unable to change the bug's version or status, add a comment to the bug and someone will change it for you.) Thanks for your help, and we apologize again that we haven't handled these issues to this point. The process we're following is outlined here: http://fedoraproject.org/wiki/BugZappers/F9CleanUp We will be following the process here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping to ensure this doesn't happen again. This bug has been in NEEDINFO for more than 30 days since feedback was first requested. As a result we are closing it. If you can reproduce this bug in the future against a maintained Fedora version please feel free to reopen it against that version. The process we're following is outlined here: http://fedoraproject.org/wiki/BugZappers/F9CleanUp This problem is still present in rawhide/F9.
To reproduce:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
dd if=/dev/zero of=somefile bs=1024 count=1024
n=$(sudo /sbin/losetup -f -s somefile)
sudo /sbin/mke2fs $n
sudo /sbin/losetup -d $n
mkdir mntpoint
sudo mount somefile mntpoint -o loop
sudo chown -R $(id -u):$(id -g) mntpoint
dd if=/dev/zero of=mntpoint/full bs=1024 count=1024
while touch mntpoint/f$RANDOM; do :; done
cat > t.c <<EOF
#include <stdio.h>
int main(void) {
puts ("hello world");
return 0;
}
EOF
strace -E TMPDIR=mntpoint gcc -c t.c
sudo umount mntpoint
rm somefile
rmdir mntpoint
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If the compiler fails to proceed press C-c to interrupt it.
Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Created attachment 312263 [details]
Do not loop for TMP_MAX times, it takes ages. Output proper error messages before aborting when mkstemps fails.
It actually does not loop infinitely, it loops "only" 238328 times (on my
machine), after which it aborts without explaining why. Patch fixes both
issues.
Sample output:
Cannot create temporary file in /vda/srcdevel/gcc/testdir/: Permission denied
./z.sh: line 13: 22173 Aborted TMP=$PWD/testdir gcc -o t t.c

Updated patch (style fixes)
Submitted the patch upstream, it should appear here today: http://sources.redhat.com/ml/libc-alpha/2008-09/ The patch has been committed over a month ago and is in gcc-4.3.1-6 and above. |
Description of problem: Running the compiler to link an executable results in an endless loop if /tmp is full. Version-Release number of selected component (if applicable): gcc-4.1.1-18.x86_64 How reproducible: always Steps to Reproduce: 1.fill up /tmp 2.compile any toy program 3. Actual results: strace output like this: 2419 open("/tmp/ccbEA47Z.c", O_RDWR|O_CREAT|O_EXCL, 0600) = -1 ENOSPC (No space left on device) 2419 open("/tmp/ccCFC47Z.c", O_RDWR|O_CREAT|O_EXCL, 0600) = -1 ENOSPC (No space left on device) 2419 open("/tmp/cc3GE47Z.c", O_RDWR|O_CREAT|O_EXCL, 0600) = -1 ENOSPC (No space left on device) 2419 open("/tmp/ccuIG47Z.c", O_RDWR|O_CREAT|O_EXCL, 0600) = -1 ENOSPC (No space left on device) Expected results: Error message about full filesystem Additional info:
