AW: AW: [OpenAFS] Can anyone reproduce this under LINUX (was: temporaryreference files do not disappear)

[Rubino Geiß]

Hi!

Sorry but I cannot reproduce the issue (with a simple program; see
below). I even modified the code not to close the file: but still no
.__afsXXX remains. The only thing I can see is, that a file remains
there for say 10 to 60 sec. after the program has terminated and the
disappears. I tested it on FileServer 1.2.3 and 1.2.4 and i386 RedHat
7.2 and 7.3.

I have no idea what kind of code is triggering the issue... but what
happens if the connection to the server is killed during the .__afsXXX
is alive? In last weeks we had one issue with our routers (network
outage for 20 min or so).

With a tick you can do it: "./close ; ls -la ; unlog ; ls -la"

The second ls -la result in a permission denied, but if you log in again
on a different or the same workstation, die .__afs file is still there!
In my opinion this can happen if a network fails, the workstation fails
or most likely X is dieing or killed. The token becomes invalid
immediately, can someone do something against it? 

By the way, it appears that these files reside only in cache dirs of
browsers and in .gconf/. Their creation time is spread wide and there
size is not always 0. 

Bye, Ruby

PS: I reported a serious problem on my site, too. I this case help is
almost a case of death a live. So please help me. Thanx.

I wrote a short program (RH7.1) but I cannot reproduce this problem. The
program creates a file, unlinks it, prints a message, sleeps for 60
seconds, and then closes the file.  While it's sleeping I get this:

~> ls -l
total 18
drwxrwxr-x    2 warlord  mit          2048 Jun 14 18:14 .
drwxr-xr-x  104 warlord  root        16384 Jun 14 18:14 ..
-rw-rw-r--    1 warlord  mit             0 Jun 14 18:14 .__afsDA45
[7]    Done                          /tmp/test
~> ls -l
ls: .__afsDA45: No such file or directory
total 18
drwxrwxr-x    2 warlord  mit          2048 Jun 14 18:14 .
drwxr-xr-x  104 warlord  root        16384 Jun 14 18:14 ..
~> ls -l
total 18
drwxrwxr-x    2 warlord  mit          2048 Jun 14 18:15 .
drwxr-xr-x  104 warlord  root        16384 Jun 14 18:14 ..

This is the program I used.  Can you send a similarly-short program that
reliably shows the problem?

-derek

#include <stdio.h>

main ()
{
  FILE *fp;

  fp = fopen ("test", "w+");
  if (!fp) {
    perror ("fopen");
    return -1;
  }
  unlink ("test");
  printf ("test unlinked...\n");
  sleep (60);
  fclose (fp);
}
