4.0.3 - error after installation

[lionel-m]

I have installed Contao 4.0.3 with Composer. No problem until the creation of a new user in the install tool.

Error:

 FatalErrorException in localconfig.php line 3: Parse Error: syntax error, unexpected '<'

In the localconfig.php file, there are two <?php:

<?php

<?php

### INSTALL SCRIPT START ###
$GLOBALS['TL_CONFIG']['licenseAccepted'] = true;
$GLOBALS['TL_CONFIG']['installPassword'] = '***';
$GLOBALS['TL_CONFIG']['adminEmail'] = '***';
### INSTALL SCRIPT STOP ###

I assume you have already tried removing the local configuration file and repeating the installation process?

[lionel-m]

I have removed the second <?php manually...

But after that I removed the maintenance mode and it does not add the php opening tag. Only during the installation. I will reinstall to see if I can reproduce a second time.

PS: The back end displays 4.0.2

I have reproduced this issue.

And there is a problem with the debugger (?)

I have stumbled upon the same issue just now. Wasen't able to understand why though…

Here is another user with this problem: https://community.contao.org/de/showthread.php?59085-Contao-4-0-3-verf%FCgbar&p=384873&viewfull=1#post384873

Same problem here, tried with composer installation and install tool using PHP 5.6.13 and nginx 1.8

[Toflar]

Confirmed. Same here.

I have added a workaround in contao/installation-bundle@696acfd.

The underlying problem obviously is the Config class writing twice into the same file. The two persistConfig() calls were so close behind each other that it led to a race condition.

However, I thought we had fixed this potential issue a long time ago? @contao/developers /cc

[Toflar]

I cannot recall but I would've used the LockHandler to work around this :)

[leofeyer]

Turned out it was not a race condition. Fixed in e6bc7ad.

[aschempp]

So this would also be a bug in Contao 3 right? If one saved the localconfig twice it would happen?

[leofeyer]

No, Contao 3 is not affected, because of this line, which has only been added in Contao 4 to solve the issue that you can only call Config::save() once in Contao 3.

Ah, thanks for the info.
