DOCUMENT_ROOT not set correctly when VirtualDocumentRoot is used
Last modified: 2008-02-15 01:34:22 EST
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0 Description of problem: I am writing a php script that indexes directories (a "directory indexer"). I have configured apache to use the VirtualDocumentRoot directive so it is easier to set up virtual hosts. While troubleshooting a problem with directories not being displayed correctly, I noticed that $_SERVER["DOCUMENT_ROOT"] is not set correctly-- in fact, it is set to "/etc/httpd/htdocs" which does not exist. I have not tested in a "normal" virtual host environment, but I "assume" the problem does not exist there. Version-Release number of selected component (if applicable): httpd-2.0.51-1.6.legacy How reproducible: Always Steps to Reproduce: 1. configure apache using VirtualDocumentRoot 2. call phpinfo() and examine value for $_SERVER["DOCUMENT_ROOT"] 3. on my machine it is /etc/httpd/htdocs which does not exist, and it is invalid. Actual Results: wrong value for DOCUMENT_ROOT Expected Results: correct value for DOCUMENT_ROOT Additional info:
DOCUMENT_ROOT is just the value of the DocumentRoot setting; it's also not affected by Alias etc. (VirtualDocumentRoot is much like a clever Alias). Can you use SCRIPT_FILENAME or such instead?
in my case, SCRIPT_FILENAME is set to "/nfs/gate/common/directoryindex.php" which is the filesystem path to the directory indexer script. REQUEST_URI is set to, for example, "/projects". In order to access that directory on the filesystem, I would normally prepend DOCUMENT_ROOT, but since it does not have the right value I cannot do it that way. I looked through all of the $_SERVER variables to see if there was something I could prepend reliably to make this work, and DOCUMENT_ROOT is the only thing I could come up with. please let me know if you need more information-- I can attach httpd.conf and directoryindex.php if that will help.
Fedora Core 1 is maintained by the Fedora Legacy project for security updates only. If this problem is a security issue, please reopen and reassign to the Fedora Legacy product. If it is not a security issue and hasn't been resolved in the current FC5 updates or in the FC6 test release, reopen and change the version to match. Thanks! NOTE: Fedora Core 1 is reaching the final end of support even by the Legacy project. After Fedora Core 6 Test 2 is released (currently scheduled for July 26th), there will be no more security updates for FC1. Please use these next two weeks to upgrade any remaining FC1 systems to a current release.
I have long since upgraded the host in question to FC4, and it has the same issues with DOCUMENT_ROOT. DOCUMENT_ROOT *should* be set to '/nfs/zoidtechnologies.com/gate/<host>/<port>/html/', but instead it is '/var/www/html' I've changed the version information on this bug so it is accurate.
Fedora Core 4 is not maintained anymore. Setting status to "INSUFFICIENT_DATA". If you can reproduce this bug in the current Fedora release, please reopen this bug and assign it to the corresponding Fedora version.
