Cache permissions, dreamhost and fastcgi

Hello all, i’m running a modx install (0.9.6.2 rev 4077) on dreamhost: Apache/2.2.9 (Unix) PHP/4.4.9 mod_ssl/2.2.11 OpenSSL/0.9.8c mod_fastcgi/2.4.6

For some reason some cache files are being generated with: -------- (blank) permissions resulting in this kind of an error:



what weird about this is that most of the cache files are generated with the correct permissions 644 and about 30% of the files with blank ones.

I tried clearing the cache, changing the file permissions in the file manager, but nothing helps. Is there a work around for FastCGI servers or there is something else going on here?

I also noticed this:
My File Manager Path: /home/thatguysocrates/DOMAIN.com/ but my Resource path: /mnt/local/home/thatguysocrates/DOMAIN.com/assets/
Can it cause the issue?

Thanks for any help!

Got a reply from dreamhost:

As far as the sessions, you’re on a standard webserver with local
storage, so I’m not sure why you’d be seeing issues. We used to actually
mount customer storage over NFS, but we’ve phased that out...so there
shouldn’t be any weirdness there. I would suggest contacting the
developer and asking what might cause the software to write files with
those permissions. We’ll be happy to share any info about our server
configuration.

Which file is responsible for generating the cache files?
Can i hard code the permissions in there somehow?

Thanks!

Ok seems like the resource path should be: /home/thatguysocrates/DOMIAN.com/ without /mnt/local/ - how can i fix it? The path is generated automatically...

Analogy problem

Check file permissions; sounds like the umask for the user running PHP (in fastcgi, this would be the same as your account that you use for ftp) may not be set properly so files are written without proper default permissions (e.g. 0644).

Hi It’s one year now. But then i managed to solve problem by little hacking..

postProcess() function in document.parser.class.inc, line 596

function postProcess() {
// if the current document was generated, cache it!
if ($this->documentGenerated == 1 && $this->documentObject[’cacheable’] == 1 && $this->documentObject[’type’] == ’document’ && $this->documentObject[’published’] == 1) {
$basepath= $this->config["base_path"] . "assets/cache";
// invoke OnBeforeSaveWebPageCache event
$this->invokeEvent("OnBeforeSaveWebPageCache");
if ($fp= @ fopen($basepath . "/docid_" . $this->documentIdentifier . ".pageCache.php", "w")) {
// get and store document groups inside document object. Document groups will be used to check security on cache pages
$sql= "SELECT document_group FROM " . $this->getFullTableName("document_groups") . " WHERE document=’" . $this->documentIdentifier . "’";
$docGroups= $this->db->getColumn("document_group", $sql);

// Attach Document Groups and Scripts
if (is_array($docGroups)) $this->documentObject[’__MODxDocGroups__’] = implode(",", $docGroups);

$docObjSerial= serialize($this->documentObject);
$cacheContent= $docObjSerial . "<!--__MODxCacheSpliter__-->" . $this->documentContent;
fputs($fp, "<?php die(’Unauthorized access.’); ?>$cacheContent");
fclose($fp);
}
}

// Useful for example to external page counters/stats packages
if ($this->config[’track_visitors’] == 1) {
$this->invokeEvent(’OnWebPageComplete’);
}
// end post processing
}

i changed to:

function postProcess() {
// if the current document was generated, cache it!
if ($this->documentGenerated == 1 && $this->documentObject[’cacheable’] == 1 && $this->documentObject[’type’] == ’document’ && $this->documentObject[’published’] == 1) {
$basepath= $this->config["base_path"] . "assets/cache";
// invoke OnBeforeSaveWebPageCache event
$this->invokeEvent("OnBeforeSaveWebPageCache");

// get and store document groups inside document object. Document groups will be used to check security on cache pages
$sql= "SELECT document_group FROM " . $this->getFullTableName("document_groups") . " WHERE document=’" . $this->documentIdentifier . "’";
$docGroups= $this->db->getColumn("document_group", $sql);

// Attach Document Groups and Scripts
if (is_array($docGroups)) $this->documentObject[’__MODxDocGroups__’] = implode(",", $docGroups);

$docObjSerial= serialize($this->documentObject);
$cacheContent= $docObjSerial . "<!--__MODxCacheSpliter__-->" . $this->documentContent;

file_put_contents($basepath . "/docid_" . $this->documentIdentifier . ".pageCache.php", "<?php die(’Unauthorized access.’); ?>" . $cacheContent);
if(!is_readable($basepath . "/docid_" . $this->documentIdentifier . ".pageCache.php"))
unlink($basepath . "/docid_" . $this->documentIdentifier . ".pageCache.php");

}

// Useful for example to external page counters/stats packages
if ($this->config[’track_visitors’] == 1) {
$this->invokeEvent(’OnWebPageComplete’);
}
// end post processing
}

So now the function checks if just created file is readable - if not removes it. There will be no errors in the frontent about inaccessable cache files.

I still dont know why that was but the error occured becaouse SOMETIMES newly created files had premissions "---" (yes ---) not "664".

Solutions worked for me
