Symlinks as Document roots are breaking the cache
Added by Frederik Vosberg about 10 years ago.
Updated almost 6 years ago.
Description
Hi there,
my hoster uses symlinks to the document root to resolve the domain to the document root.
- If there is a host-specific pseudo-DocumentRoot, use it instead of the default one
RewriteCond %{REQUEST_URI} !^/f?cgi-bin/
RewriteCond /var/www/virtual/julia/%{HTTP_HOST} -d
RewriteRule (.*) /var/www/virtual/julia/%{HTTP_HOST}$1
That causes errors when trying to load file paths with GeneralUtility::getFileAbsFileName() because the PATH_typo3 constant contains the current document root. (the current domain of this request).
But the cache holds absolute paths to the symlink document root of the request which triggered the caching.
So the getFileAbsFileName returns empty filePaths, because the absolute file paths passed to it didnt start wih the PATH_typo3.
So we have to realpath them before checking.
Im going to push a patch to gerrit, give me a minute it is my first time ;)

Can you point out which cache entries are written with realpath and describe in which context GeneralUtility::getFileAbsFileName() fails?
Hello Helmut,
we have similar problems on our servers. Apache runs on a symlink /www -> /kunden and if you are logged in by SSH "pwd" shows you /kunden.
So, if TYPO3 Cache was deleted and the next call comes from scheduler/CLI the Cacheentries will be created with /kunden.
If you then try to call Login screen of TYPO3 Backend the whole CSS is broken. The path to these files are wrong. To create relative paths the Core removes the amount of letters of PATH_site from the absolute paths in Cache. In our case we have a difference of 2 letters.
After clearing the cache and call BE again it works.

This issue you describe is resolved with https://review.typo3.org/#/c/31565/ and is included since 6.2.5
Thank you Helmut for searching this ticket. I just have created a new instance with current master and you're right. It works now.
