Bug #25292
closed
Exception "tx_em_Parser_MirrorXmlPushParser: Unable to create XML parser" when updating extension list
100%
Description
This happens both when clicking on the Retrieve/Update button in the new extension manager and when using the Update Extension List task in T3 4.5.2 (Side note: I had to fix the requireOnce() call in class.tx_em_parser_mirrorxmlabstractparser.php first, but this is already removed in SVN).
In tx_em_Repository_Utility->updateExtList(), isExtListUpdateNecessary() is called which calls getRemoteExtHashFile(). After this fetchExtListFile() is called which calls getRemoteExtListFile(). Both getRemoteExtHashFile() and getRemoteExtListFile() call getMirrors(TRUE) which result in tx_em_Import_MirrorListImporter->getMirrors() and tx_em_Parser_MirrorXmlPushParser->parseXML() calls.
And here is the source of the problem: The XML parser (objXML member) is created in the constructor of the tx_em_Parser_MirrorXmlPushParser class, but freed at the end of the parseXML() method. Therefore, in the second call to parseXML() objXML is not a resource any more and the exception is thrown.
My current solution is to move the following lines from tx_em_Parser_MirrorXmlPushParser __construct() to the beginning of method parseXML():
if ($this->isAvailable()) {
$this->objXML = xml_parser_create();
xml_set_object($this->objXML, $this);
}

The bug is still present in TYPO3 4.5.3 and can be solved in the same way.
But it might not appear on many systems since most users will run PHP >= 5.1.0. Then, tx_em_Parser_MirrorXmlPullParser is available which runs without problems.
In our case, PHP was compiler without xmlreader, which is necessary for the pull parser. Therefore, the push parser was used - with the effects described above.

I also ran into this. It turns out that the PHP used is also compiled without xmlreader.

I also ran into this bug on Typo3 4.5.4. But the fix above works.

Had the same Problem with TYPO3 4.6.1
After installing xmlreader for php it works.

Why did you change "Done" to 100%? It's not done - if the push parser is used because xmlreader is not present the problem still occurs!
Either fix it or remove the whole push parser. I switch this back to 0%...

What version of PHP? Why is xmlreader not available?
Updated by Stanislas Rolland about 12 years ago
I am not able to reproduce this issue with TYPO3 4.6.4. Please explain how to reproduce.

I had this error as well for a couple of months on a server, however, I didn't have much time or need to fix it until now.
It affected TYPO3 version 4.5.4 - 4.5.11 on my system, although, a missing php component is really to blame ..
In TYPO3 Log
Core: Error handler (BE): PHP Warning: filemtime(): stat failed for /opt/www/www.domain.com/html/typo3temp/extensions.xml.gz in /opt/www/TYPO3/typo3_src-4.5.11/typo3/sysext/em/classes/index.php line 2466
With Centos 6 / RHEL 6, I believe the default Php build comes with xmlreader disabled, the only thing I had to do was to install the php-xml package on my server.
Here's a quick how to for federa/centos/red-hat servers, assuming you have the right repositories set up.
sudo yum install php-xml.x86_64

I have Fedora 16 installed in a VM and just tried to update the extension list - same error. I also had to install php-xml manually. But it would be better if the push parser was working...

I could this reproduce only with TYPO3 4-5 branch (4.5.25). (not with TYPO3 4-7)
Looks like this is originally is caused by an ExtDirect issue. However, the pushed patch to Gerrit resolves the issue by adjusting the Parser class.
