Problem with upgrading - related to exec()?

Hi,

I've seen a similar post recently regarding exec() and upgrading to G1 v1.44. I've just this evening started to upgarde to 1.44 from a 1.44-rc2, and I now get the "serious error" relating to exec() function when running the configuration wizard.

Has something changed in the code? all was working well in the rc2, and the upgrade wen't like clock work. I'll mail my hosting provider (www.hosting-unlimited.net) but I would hope that they would mail me when there was to be a change as major as this.

Appreciate any assistance.

Thanks,

Stuart

Hi,

I've been using G1 for many many months now, and I still continue to do so with the 1.44-rc2. This can be seen at www.crump.co.uk/gallery

However, as I said I upgraded to the gold version of 1.44 and it no longer works, well it no longer allows me to complete the config wizard after uploading the new G1 files/code.

The results from the php statement listed in the FAQ are:

system, shell_exec, popen

So does that mean exec() is disabled? and if so how is gallery installed and working up till now?

Stuart

I should be able to run the config wizard. Where can I get the new code? will it be in the CVS library?

Many thanks for being v.responsive.

tomcat76, if you just upgraded from a previously operational Gallery, you should be able to ignore the message. (Unless your host disabled something at the same time you upgraded.)

If exec is disabled, Gallery would have never worked, so if you have a working installation, it's probably safe to ignore. It's probably a false positive by the script accidentically catching "shell_exec" for "exec"

Just ignore the error. The error doesn't cause setup to do anything differently... it just tells you that it probably won't work.

On step 4?

Locate the error in red.. what is it?

Sorry.. yes. You can replace a bit of code.

Find

        if (!empty($disabled) && eregi("exec", $disabled)) {
                $fail["fail-exec"] = 1;
        }
        else {
                $success[] = _("<b>exec()</b> is not disabled on this server.");
        }

in the "check_exec" function of setup/functions.inc

and replace it with

        if (!empty($disabled)) {
                foreach(explode(',', $disabled) as $disabled_func) {
                        if(eregi('^exec$', $disabled_func)) {
                                $fail["fail-exec"] = 1;
                        }
                }
        }
        
        if (empty($fail['fail-exec'])) {
                $success[] = _("<b>exec()</b> is not disabled on this server.");
        }

I've changed the code in functions.inc as noted in the discussion but how will that affect any further upgrades? Can I assume that this code change is now incorporated in the 1.x code stream?

Again, thanks for jumping on this one for me and for others.

Please look out for a PayPal donation, your doing a top notch job.

My fresh install was doing exactly that... and the above code change cured that, it did for me and allowed me to complete the installation.

I concur with what you are saying...

If you change the code and it works in G1 1.44 then exec() was a false positive, essentially exec() is actually enabled on your hosting companys system and it's just G1 reporting this incorrectly. Now, if you change this in the code and it still doesn't work then your web hosting company has this exec() function disabled for security reasons.

I hope this is clear.

So, it works, or it doesn't work...?

Let me try to clarify:

1. My webhost Lunarpages has disabled EXEC.

2. Until the recent version 1.4.4 of Gallery, I did get errors during installation but it did complete.

3. When installation was finished, I changed the fs_unix.php file to use the PASSTHRU command and not EXEC... AND I have been running many versions of Gallery, and right now on two galleries on version 1.4.3pl2... on my Lunarpages host... that has EXEC disabled.!

(I use Gallery Remote for uploading)

So for years I have been running Gallery (slightly modified) on a host with EXEC disabled.

4. NOW, from version 1.4.4 the script not only reports error during installation.... BUT completely stops without any way of getting everything installed... and modifying it as before.

5. SO back to initial question.... how do I get the installation script to run despite the errors..... ???

6. Seems only option is to leave Gallery at 1.4.3 or leave Gallery for good, as it has become almost impossible to use this great script unless you host your own environment.

Hello Signe,

Are you referring to your earlier help with modifying functins.inc?....

I did try to modify it, but the install script still stops after the exec check..

So I guess it will take some more to disable it completely.

About the PASSTHRU command, it's actually just one line in fs_unix that is changed.... and after that Gallery has been working very great.

Since Gallery is the best script found, it would really be great with a workaround, since many many hosts now have stopped EXEC... so more and more people have problems running Gallery....

Will G2 have same problem?

I changed the check for exec() to passthru, and together with the change in fs_unix.php I know run Gallery 1.4.4 on a system with exec() disabled.

So it can be done.... even if there is still a warning when running the config wizard...

But I know have a fully functional Gallery... :lol: so why bother that it is not supposed to work.... :D

peh - What should the syntax be for the new passthru line? I changed exec to passthru to get through the config, but it's giving me an incorrect number of arguments error when I try to upload images.

NEVERMIND!!!! I found it here>
