init_header error

[refreshmentshop]

We have a strange error with file permissions with our new zencart installation (v1.3.8)

Zencart is telling us that our configure.php is writeable despite the fact we have set permissions as 644 and confirmed they are set. (444 and 400 give the same result)

We even used the same check that zencart uses to display the warning (is_writeable) and added it to init_header.php to confirm our suspicions.

if(is_writeable($check_path))
{
echo ("$check_path is writeable");
}
else
{
echo ("$check_path is not writeable");
}

This tells us at the top of the page that configure.php IS NOT writeable, followed by the zencart warning that IT IS???

For now we have just disabled the warning (I know, I know), but it would be nice if we could get to the route of the problem.

Are you using is__writable (with 2 underscores) or just is_writable (just one underscore)?
v1.3.8 uses is__writable for the check, which actually attempts to open the file with the intent to write to it. If that attempt to open the file passes, it's reporting that the file is writable ... because it is.

If you don't believe it, that's your choice. Just turn off the warning and it won't bother you anymore.

Thanks DrByte, I can't believe someone would be stupid enough to make the difference between two commands, two underscores instead of one. Thats just asking for buggy code!

Any idea how I could make the file non-writable? The trouble is we are running i5/OS PASE on a IBM AS400 () and the shell tells us the permissions have been set. I'm wondering if zencart is just ignoring the permissions.

Perhaps Apache could be configured incorrectly, allowing php to modify write-protected files, is this even possible?

Thanks. There was very good reason behind that decision. The code's not buggy. It's actually being more thorough than most. :)

If you trust it, just turn off the warning.

Zen Cart relies on what PHP determines when it talks to the filesystem. It's the filesystem that allows or denies the write behavior.

Perhaps Apache could be configured incorrectly, allowing php to modify write-protected files, is this even possible?

If PHP is running with a higher level of permissions than Apache (perhaps as suPHP?), you could be getting more permissions than normally expected. In this case, the file is still writable according to the filesystem, unless you pare back the permissions even tighter ... but then you run the risk of PHP not being able to read the file at all.
In that case you are likely left with no choice but to disable the warning.

I didn't mean it was a bad idea to use the command, it's a very good idea. Just the way that command was written, you can't see the difference between one and two underscores, a different name for the new command, like can_write would have been better (Not zen's fault)

I guess we will just give up and disable the warning...

I'm not really a coder anyway, I'm a designer. Someone give me a Mac and a darkened room, I'm getting a headache.

Yes, definitely the best environment!
