Installation of 4.3.7 ME at All-Inkl not possible

[jscholtysik]

My system:

Provider: All- Inkl Premium PHP: 5.6.29-nmm1 (cli)

I made the following steps at All-Inkl:

1. Created a subdomain: contao4.domain.de

2. Installed Composer in the root directory with:

curl -sS https://getcomposer.org/installer | php

3. Installed Contao 4.3.7 with:

php composer.phar create-project contao/managed-edition contao

4. Changed the DocumentRoot to /contao/web:

The install.php is not reachable under sub.domain.de/install.php and the following error message appears:

Fatal error: Uncaught exception 'Symfony\Component\Filesystem\Exception\IOException' with message 'Using the Contao\ClassLoader class has been deprecated and will no longer work in Contao 5.0. Use the Composer autoloader instead.' in /www/htdocs/w016bce8/contao/vendor/symfony/symfony/src/Symfony/Component/Filesystem/LockHandler.php:86 Stack trace: #0 /www/htdocs/w016bce8/contao/vendor/contao/core-bundle/src/Command/AbstractLockedCommand.php(32): Symfony\Component\Filesystem\LockHandler->lock() #1 /www/htdocs/w016bce8/contao/vendor/symfony/symfony/src/Symfony/Component/Console/Command/Command.php(265): Contao\CoreBundle\Command\AbstractLockedCommand->execute(Object(Symfony\Component\Console\Input\ArgvInput), Object(Symfony\Component\Console\Output\BufferedOutput)) #2 /www/htdocs/w016bce8/contao/vendor/contao/installation-bundle/src/Controller/InstallationController.php(170): Symfony\Component\Console\Command\Command->run(Object(Symfony\Component\Console\Input\ArgvInput), Object(Symfony\Component\Console\Output\BufferedOutp in /www/htdocs/w016bce8/contao/vendor/symfony/symfony/src/Symfony/Component/Filesystem/LockHandler.php on line 86

Can you try sub.domain.de/contao/install instead, please?

[jscholtysik]

Using this path the following error is in /var/logs/prod.log:

[2017-04-19 15:30:50] request.INFO: Matched route "contao_install". {"route":"contao_install","route_parameters":{"_scope":"backend","_token_check":true,"_controller":"Contao\InstallationBundle\Controller\InstallationController::installAction","_route":"contao_install"},"request_uri":"http://contao4.bitsandmedia.de/contao/install","method":"GET"} [] [2017-04-19 15:30:50] app.CRITICAL: An exception occurred. {"exception":"[object] (Symfony\Component\Filesystem\Exception\IOException(code: 0): Using the Contao\RequestToken class has been deprecated and will no longer work in Contao 5.0.

Does the issue also occur if you download and install the .zip package from contao.org instead of using composer create-project?

[jscholtysik]

Yes, same error.

Did you try it with PHP 7 instead? I successfully installed C4 at All-Inkl some days ago - but I used PHP 7.

[jscholtysik]

No, I haven't tried it yet, but I think Contao 4.3 ME should run also on PHP 5.6 without any problems, because the system requirements specify a minimum of PHP 5.5.

Could you please try if the Contao check finds any problems with your webspace?

[jscholtysik]

I checked my webspace, no error appears in the Contao check 12.0:

I don't think this is something the Check would be able to detect. It appears the E_USER_DEPRECATED errors are thrown and then catched by Symfony's LockHandler for some reason and then thrown again as IOExceptions.

I think the problem is that in LockHandler.php:71-87 the fopen() call fails but error_get_last() doesn’t get the right error message.

Today I tried my installation of Contao 4 at All-Inkl once more with PHP 7.1 CGI/FPM: No problem and the install tool start page appeared. Then I tried PHP 5.5 CGI/FPM, also no problem and also here the install tool start page appeared. Then I tried again PHP 5.6 CGI/FPM. Now also this configuration worked flawlessly and also here the install tool worked... Very strange and without any changes of the configuration with PHP 5.6 CGI/FPM

Sorry and thanks for your efforts!

Since the problem occurred within the LockHandler, I suspect it was simply a (temporary) problem with the CGI handler on the webserver and not within PHP or Contao itself.
