Autoloader not working? about selfoss

[aurora]

Puh ... strange things going on here ... i managed to track this down to a strange issue with "glob" in environments, where "open_basedir" is set. apparently 'glob' returns 'false' here instead of an empty array, even though the path it's trying to glob is valid compared to the "open_basedir" settings. I've turned "open_basedir" off, for this single host, but the autoloader still fails to locate / load the class. the new error message is:

Undefined class helpers\Logger

#0 /var/www/clients/client2/web75/web/libs/f3/base.php:1698 F3::error(500,'Undefined class helpers\\Logger')

Are there any known issues with f3 on shared hosting environments? I was not able to dig anything up in the f3 forum regarding this ... :-(

Thats curious, I use selfoss also on a shared environment (PHP 5.3.6) and it works fine. I have no idea what the reason could be. Its hard without debugging :/

[aurora]

Mmmm ... i somehow expected this to be your answer. I will try to debug this and probably it turns out to be no issue with selfoss. I did not have any similar issues with any other PHP based software on this machine, though, and i am running quite a lot of different stuff on it. This is really strange ...

[aurora]

YES!!! seems i found the problem, and indeed it had nothing to do with selfoss nor f3. The bug can be closed. Sorry for bothering you with this, Tobi. But maybe other users of selfoss are running into the same issues than me, and so here are my conclusions:

1. There seems to be a serious problem with glob and open_basedir. The problem is, that with open_basedir enabled glob will return false instead of an empty directory, if no files are found regarding search-pattern and glob settings. This problem was already reported to php dev-team in 2009 but was closed as "bogus" [sic!]: https://bugs.php.net/bug.php?id=47358 -- that was the reason for the first error i got (Invalid argument supplied for foreach()). Maybe a solution would be to prevent f3 to use E_STRICT for error-reporting (see: libs/f3/base.php, line 1687)

2. "Undefined class helpers\Logger" -- if you are using ISPConfig as managment software for your server, the following might be the problem, why helper classes are not found. ISPConfig seems to apply some strange rights for the the document-root of the virtual host:

   drwx--x--- 13 web75 client2 4,0K 2011-10-04 23:48 web
   

   It's not clear to me, why ISPConfig does not apply the right for reading the directory for the group (client2). After adding it

   chmod g+r web
   

   f3 autoloader has no further issue locating classes found in a subdirectory of document-root (like the helper classes).

Well, I sorted it out as well. Posting what I changed here in case someone its the same trouble:

On ISPConfig (with this it works for me)

SuExec - Checked
PHP - ModPHP

Then, on Options, Apache Directives:

php_admin_value open_basedir none
