Bug #75721
closedUpdating extension list fails in Typo3 6.2.21
100%
Description
Steps to reproduce:
1. Log in the backend
2. Click on Admin Tools -> Extension Manager
3. Select "Get Extensions"
4. Click on "Update Now"
Actual result:
A pop-up appears: "Update Extension List error(Internal Server Error):"
(see attached screenshot)
Expected result:
Extension list is updated.
Note: The issue started after upgrading from Typo3 6.2.19 to 6.2.21. Downgrading to 6.2.19 again and retesting showed that updating the extension list works again. Hence, assuming a regression in 6.2.20 or 6.2.21 here.

Can you take a look at the server logs please? The error.log should contain more info.

Here's the related Apache log entry:
PHP Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 39583744 bytes) in /var/www/typo3/typo3_src/typo3/sysext/extensionmanager/Classes/Utility/Parser/ExtensionXmlPullParser.php on line 59, referer: http://luke1410.de/typo3/typo3/mod.php?M=tools_ExtensionmanagerExtensionmanager&moduleToken=af02d9ff8b0c8071512e8b76bc1d537efe584142&tx_extensionmanager_tools_extensionmanagerextensionmanager%5Baction%5D=ter&tx_extensionmanager_tools_extensionmanagerextensionmanager%5Bcontroller%5D=List

I had the same issue on one installation.
The memory_limit was set to 64M in php.ini - increasing it to suggested 100M solved the issue for me.

I think, I have a similar issue with 6.2.21:
When I try to upload my extension list, I get the following message:
Unable to parse file resource compress.zlib:///kunden/homepages/39/d71054028/htdocs/myWebpage/typo3temp/1.extensions.xml.gz.
The Typo3 log shows three errors:
Core: Error handler (BE): PHP Warning: XMLReader::XML(): Unable to load source data in /homepages/39/d71054028/htdocs/myWebpage/typo3_src/typo3/sysext/extensionmanager/Classes/Utility/Parser/ExtensionXmlPullParser.php line 59 Core: Error handler (BE): PHP Warning: XMLReader::XML(): Memory allocation failed : growing buffer in /homepages/39/d71054028/htdocs/myWebpage/typo3_src/typo3/sysext/extensionmanager/Classes/Utility/Parser/ExtensionXmlPullParser.php line 59 Core: Error handler (BE): PHP Warning: XMLReader::XML(): Memory allocation failed : growing buffer in /homepages/39/d71054028/htdocs/myWebpage/typo3_src/typo3/sysext/extensionmanager/Classes/Utility/Parser/ExtensionXmlPullParser.php line 59My PHP Settings:
- PHP 5.6.20
- memory_limit 256MB
- xml support enabled
- zlib registered
Unfortunately, I do not have access to the server error log files...
A downgrade to 6.2.19 solves the problem.

Interesting... the error in issue #75022 was "unable to open source data", the report here is "unable to load source data".
- https://github.com/php/php-src/blob/PHP-5.6.20/ext/xmlreader/php_xmlreader.c#L893
- https://github.com/php/php-src/blob/PHP-5.6.20/ext/xmlreader/php_xmlreader.c#L1118
The reader
is initialized using libxml2 functions:
- https://github.com/GNOME/libxml2/blob/master/xmlreader.c#L2070 (xmlNewTextReader)
- https://github.com/GNOME/libxml2/blob/master/xmlreader.c#L5401 (xmlReaderForFile)
So, in general... the issue we tried to solve in #75022 is still present and the work-around only works for parts.
From my point of view, it makes sense to upgrade libxml2 on the systems where this happens.
Updated by Stephan Großberndt over 8 years ago
As stated in https://forge.typo3.org/issues/75022 there are cases where libxml 2.9.1 does work and 2.9.2 doesn't - so I don't think this will help.

In my case, I am using libxml 2.7.8 and it doesn't work.

I have the same Problem with 7.6.6
Memory allocation failed : growing buffer in ... ExtensionXmlPullParser.php line 60
The site is hosted by 1&1

I'm also using 1&1 as hosting provider. But until now, I never faced any problems with my TYPO3 and 1&1...

Just updated to 6.2.22: Same issue:
Core: Error handler (BE): PHP Warning: XMLReader::XML(): Unable to load source data in ...typo3_src/typo3/sysext/extensionmanager/Classes/Utility/Parser/ExtensionXmlPullParser.php line 59 Core: Error handler (BE): PHP Warning: XMLReader::XML(): Memory allocation failed : growing buffer in ...typo3_src/typo3/sysext/extensionmanager/Classes/Utility/Parser/ExtensionXmlPullParser.php line 59 Core: Error handler (BE): PHP Warning: XMLReader::XML(): Memory allocation failed : growing buffer in ...typo3_src/typo3/sysext/extensionmanager/Classes/Utility/Parser/ExtensionXmlPullParser.php line 59
Memory limit is 256M, System environment check shows all green...
Any suggestions or ideas?

Hi,
I have the same problem with TYPO3 6.2.2 on a Mittwald Hosting. The "System environment check" is OK. Our TYPO3 6.2.2 systems on own webservers works correct. Very strange.
Best wishes
Björn

Hi Björn,
what is your php memory limit? I'm facing this problem with 256M RAM but according to the documentation, TYPO3 6.2 should work with only 64M.
Articles and posts about similar issues recommend increasing the limit which is unfortunately not possible in case of shared hosting providers.
Maybe someone with a Typo3 6.2 installation and root access (or at least write access to the php.ini) can try reducing the memory limit to 256M and test if the update of the extension list still works. If yes -> should be something else. If no, either the required memory limit for Typo3 should be increased or the function causing the problems should be rewritten / replaced.
Or am I wrong? Comments?
Best regards,
Jens

I looks like we should revert the change for #75022 to solve the regression with memory limits as a first step.
Then we need to focus (again) on the problems with libxml and possibly the compressed input stream.
