Rev 6799 can't add or modify snapin, blank page

[Claude Girard]

Hi

When I want to add or modify a snapin, I see a blank page.
In apache error log I have these lines:

[Fri Mar 18 09:54:19.887823 2016] [:error] [pid 2559] [client 172.20.40.1:55816] PHP Fatal error: Call to a member function chdir() on null in /var/www/html/fog/lib/fog/fogbase.class.php on line 73, referer: http://crim-fog.pu-pm.univ-fcomte.fr/fog/management/index.php?node=snapin&sub=list

I have been unable to replicate this issue. First, the chdir function isn’t used during a snapin list/search page. The error you’re seeing appears that the FTP Connection is not existing, but it’s requesting data from an area that it has NO reason to be asking for to begin with. While I don’t think the error is while you’re listing/searching snapins, it’s just odd to see the “referer” part state so. With all of that said, can you verify your server’s FTP information?

I was able to fix the issue with the second error you see (FOGPageManager::$FOGSubMenu), but that is unlikely the thing causing your blank screen.

I also can not use snapins now after updating, if i select an existing snapin i get server error 500

[Tom Elliott]

@theWizard What have you tried? Do you have anything in error logs?

@Tom-Elliott
I’m not sure what to try except checking permissions and fog credentials which seemed ok, log consists of the following entries

Can you update and see if this is still happening? I found the line 80 issue and fixed that as well.

I have a similar problem. Clicking at “Create New Snapin” brings a sever error 500.
Apache log show the following error:

[Fri Mar 18 14:53:59.605058 2016] [:error] [pid 17646] [client 10.xx.xx.xx:52947] PHP Fatal error:  Call to a member function chdir() on null in /var/www/html/fog/lib/fog/fogbase.class.php on line 73, referer: http://10.xx.xx.xx/fog/management/index.php?node=snapin

I did not created any snapins so i can not test if “List All Snapins” brings a error 500 too.
(Without snapins “List All Snapins” is working so far)

Running latest Version 6811.
What i noticed since a few updates: When i follow the instructions during the update i get no possibility to update the db schema.
I only get the normal log screen. Is this correct?

 * You still need to install/update your database schema.
 * This can be done by opening a web browser and going to:

   http://10.xx.xx.xx/fog/management

 * Press [Enter] key when database is updated/installed.

[Tom Elliott]

@jayphizzle It will only show a database update screen if there’s a database update to be performed. The warning you see there is just to ensure that you check the browser. You can just add the -y argument to the installer and it will do everything without prompting you (including updating db if there is a db update.)

[Tom Elliott]

Please update again and let me know if things are any better. I moved the ftpfilesonly function to the snapin management page. When it’s called it should have it’s proper variables set then.

@Tom-Elliott
Confirmed i can now access the snapins to edit, thank you very much

It is working for me too!

Thx @tom-elliot for another quick fix!

[Claude Girard]

Yes it’s ok for me too.

But I don’t know if you wanted that, now when I create or modify a snapin, I have no more choice box, for choosing what file present on server I want to use.
I can only upload.
so I can’t create a snapin from another one without downloading file, then reuploading it

[Tom Elliott]

@Claude-Girard Does the file actually exist on the node master that it’s uploaded too?

[Claude Girard]

@Tom-Elliott Yes. It exist.
On this screen capture is what I can see.
And when I create or update the snapin, if I download the file on my computer, and choose it for re-upload, on my server group owner for this file become “fog”, before it was “www-data”

[Tom Elliott]

I may have made a bit of regression into this issue. I only state this because I’m trying to maintain the list and make the functions that handle it work properly.

[Tom Elliott]

Fairly sure this is still fixed, and with the added benefit of properly getting the snapins from all nodes within.

Sorry but Rev 6885, again blank page in create snapin and edit snapin.

Apache error log (same error in crating or in editing snapin):
