#4851 (ok 4.4.3) PHP errors in login dialogue

[Alexander Schuch]

I have a multi-server setup, so I use "$cfg['ServerDefault'] = 0;" in my configuration file. This already lead to some problems, so I just want to make sure I mention this.

Reproduction:

• open phpMyAdmin "root" installation
• "General Settings" page is shown, the theme can be selected and a server can be selected
• select a server ("Replication Master" in my case)
• the actual login screen is shown along with an error - see attachment

Reproduction 2:

• open phpMyAdmin "root" installation in another tab
• "General Settings" page is shown, the theme can be selected and a server can be selected
• select the same server as in "reproduction"
• There is no login screen anymore, as the session is still valid.
• The PHP warnings are shown in the main window on the right. - Same warnings as before.

Cannot reproduce with 4.4.1.1 and ServerDefault set to 0.

Did you install your 4.4.1 in an empty directory, or did you overwrite a previous installation?

Which PHP version are you using?

[Alexander Schuch]

I reproduced the problem with phpMyAdmin 4.4.2 on another computer (but same server):

• Login to phpMyAdmin.
• All looks fine.
• I waited two hours. pma is configured using "$cfg['LoginCookieValidity'] = 8 * 3600; // 8 hours", so the two hours might mean nothing.
• I opened a new tab and loaded phpMyAdmin.
• I selected the server I logged in before.
• I saw the error, see attachment.

My installation work-flow is as follows:

• Download phpMyAdmin.
• Uncompress the archive; it creates a separate directory.
• Move the archive directory into a central directory "pma". This means that I collect previous versions there.
• Symlink "config.inc.php" from another central "config" location. There are separate configuration files for 4.2, 4.3 and 4.4.
• Update "htdocs" symlink to point to the new directory.

So in short, I never install an archive on top of another one - all into separate directories.

I am using a nearly stock Ubuntu 14.04 LTS installation.

PHP 5.5.9-1ubuntu4.7 (cli) (built: Mar 16 2015 20:47:39)
Copyright (c) 1997-2014 The PHP Group
Zend Engine v2.5.0, Copyright (c) 1998-2014 Zend Technologies
with Zend OPcache v7.0.3, Copyright (c) 1999-2014, by Zend Technologies

I am using Apache and mod_php5. I have a gut feeling that it possibly could be related to OPcache which possibly might not like me changing the "htdocs" symlink. I stopped and started again Apache, so the shared memory OPcache cache should be emptied. Still, I could reproduce the problem.

I have configured my browsers to remove the browser cache on each shutdown. So by tomorrow, I expect OPcache to have a new cache (Apache restart) and my browser to have a new cache as well (shutdown cleanup).

Besides that, I am out of ideas.

I've seen that this bug has been fixed already. Great!

Just for the sake of completeness, I can reproduce the issue with my very first reproduction steps.

As nothing changed at the server since yesterday, and my browser has an empty cache, I for the moment do not believe anymore that OPcache is the culprit. But I keep an eye on it, though.

Should be fixed with https://github.com/phpmyadmin/phpmyadmin/commit/fe3a103767bd5f68a89d2527c29ad1f2bcffc54a
