i would check the permissions of the parent directories.
also, if you happen to be writeing to a samba or sharity share permissions tend to get wacky from time to time.
being it happens at a semi regular intervel. (look like every 6-7 hours or so)
is it always the same upload directory you are haveing any errors? or is it always a random user in a random directory?
implamenting a new function to chmod the file in perl should just be adding a new function that accepts 1 paramerter and that should be the fullpath to the file.
at a command prompt umask -S should show you the current umask perms in a more readable format.
Code:
use@host$ perldoc -f umask
umask EXPR
umask Sets the umask for the process to EXPR and returns
the previous value. If EXPR is omitted, merely
returns the current umask.
The Unix permission "rwxr-x---" is represented as
three sets of three bits, or three octal digits:
0750 (the leading 0 indicates octal and isn't one of
the digits). The "umask" value is such a number
representing disabled permissions bits. The
permission (or "mode") values you pass "mkdir" or
"sysopen" are modified by your umask, so even if you
tell "sysopen" to create a file with permissions
0777, if your umask is 0022 then the file will
actually be created with permissions 0755. If your
"umask" were 0027 (group can't write; others can't
read, write, or execute), then passing "sysopen"
0666 would create a file with mode 0640 ("0666 &~
027" is 0640).
Here's some advice: supply a creation mode of 0666
for regular files (in "sysopen") and one of 0777 for
directories (in "mkdir") and executable files. This
gives users the freedom of choice: if they want
protected files, they might choose process umasks of
022, 027, or even the particularly antisocial mask
of 077. Programs should rarely if ever make policy
decisions better left to the user. The exception to
this is when writing files that should be kept
private: mail files, web browser cookies, .rhosts
files, and so on.
If umask(2) is not implemented on your system and
you are trying to restrict access for yourself
(i.e., (EXPR & 0700) > 0), produces a fatal error at
run time. If umask(2) is not implemented and you
are not trying to restrict access for yourself,
returns "undef".
Remember that a umask is a number, usually given in
octal; it is not a string of octal digits. See also
"oct", if all you have is a string.
Thanks for the advice. To answer your question, it's always a random user in a random directory. We're about half-way through changing our scripts to manually chmod the uploaded file, so I think I'm going to just let this problem go. I have one last thing to post; maybe this will be the secret ingredient needed to figure out this problem. We ran into the problem consistently again (which makes it roughly every 3 hours now), so I did
Code:
ps -ef > psbad.txt
and restarted apache. We had tried this a couple of weeks ago and it fixed the problem then. Again, it fixed the problem. So I did
Code:
ps -ef > psgood.txt
I'll load those files zipped in case anyone wants to look at it to see if they can figure out what the problem is. It looks to me like the same processes are running at both times, which makes me all the more confused. Thanks everyone for helping me out with this.
No, we don't get errors with those scripts. I've always been curious why they occasionally come up as scriptname <defunct>, but have never really payed attention to it because they always work.
So I started roaming around looking for apache httpd bugs and found one that says
Quote:
mod_cgid in Apache before 2.0.48, when using a threaded MPM, does not properly handle CGI redirect paths,
which could cause Apache to send the output of a CGI program to the wrong client
We're running apache 2.0.40. Does that mean that when these files are being uploaded they could be given the umask of a user that doesn't exist, which in turn would give the file the 600 permissions?
since the snipit specificly says that STDOUT can goto the wrong client when useing a redirect i would lean toward no i dont think this would be the problem. But it would be unwise to rule it all out.
I used the following code, which I found on the internet to upload files.

<form enctype="multipart/form-data" action="upload2.php" method="POST">
