0004354: Error installing Drupal 7 - $_SESSION is an undefined variable, 'PDOStatement' is an unknown class.

Notes
(0004993) aaron 01-23-11 20:37 edited on: 01-23-11 20:37	I can reproduce 0003971 on Resin 4.0.14, result is "false".

(0004997) domdorn 01-26-11 09:54	drush uses zend php, so the error about PDOStatement is probably not related to Querucs. If you managed to run drush through quercus, please provide information how you did it. @aaron: false is the correct result. In Quercus, as well as Zend PHP, $_SESSION is not defined if session_start() isn't called before. That's the reason for the NOTICEs above. I'm currently in the process of reproducing the error you're having. I'll keep you posted.

(0004998) aaron 01-26-11 10:53	Hi domdorn. While I downloaded Drupal via "drush dl" (as a matter of convenience; drush dl alone does not perform an install AFIAK), this is reproducible via a manual install. I only mentioned drush for completeness. Presumably if I manually downloaded drupal 6.20 it would be identical although I suppose I had better test that assumption.

(0004999) domdorn 01-26-11 10:55	aaron: are we talking about 6.20 or 7.0 here? I'm currently testing with 7.0 and can reproduce the errors you're receiving. which database are you going to use? mysql/postgresql/sqlite

(0005000) aaron 01-26-11 11:08 edited on: 01-26-11 11:13	Yes, I reproduced it with a manually downloaded drupal 7 archive: Roughly: [aaron@msi-cr620 tmp]$ wget http://ftp.drupal.org/files/projects/drupal-7.0.tar.gz [^] [aaron@msi-cr620 tmp]$ cp -pr /opt/software/resin-4.0.14/ resin [aaron@msi-cr620 tmp]$ mkdir -p resin/webapps/ROOT/WEB-INF/lib [aaron@msi-cr620 tmp]$ cp /opt/software/jdbc-drivers/mysql-connector-java-5.1.14/mysql-connector-java-5.1.14-bin.jar resin/webapps/ROOT/WEB-INF/lib/ [aaron@msi-cr620 tmp]$ cat > resin/webapps/ROOT/WEB-INF/resin-web.xml <<END <web-app xmlns="http://caucho.com/ns/resin"> [^] <welcome-file-list><welcome-file>index.php</welcome-file></welcome-file-list> <rewrite-dispatch> <dispatch regexp="\.(php\|gif\|css\|jpg\|png\|ico\|js\|html\|htm\|txt)"/> <forward regexp="^/" target="/index.php?q="/> </rewrite-dispatch> </web-app> END ... [aaron@msi-cr620 ROOT]$ tar -zxf ../../../drupal-7.0.tar.gz && mv drupal-7.0/* . [aaron@msi-cr620 resin]$ bin/resin.sh console (a correction: i've been running under the Sun VM 1.6.0_21-b06 FWIW)

(0005001) aaron 01-26-11 11:10 edited on: 01-26-11 11:18	6.20 works fine (well, at least install does, I think 6.x has been working on Quercus for a long time) I don't know why, but my uploaded screenshots appear to not be valid after download so I'm not sure if they are useful.

(0005002) aaron 01-26-11 11:34	To answer your last question, right now I was going to use mysql as I'm developing. However I have typically used postgres for production Drupal sites. (I have not tested Quercus/Drupal7/Postgres yet)

(0005003) domdorn 01-26-11 15:00	Ok, I just fixed most of the bugs in the installation procedure. However, Drupal 7 requires the filter extension, that we currently don't provide. I created an open Quercus module for it here: https://github.com/quercus/quercus-filter [^] but this will take some time to implement, so if you need Drupal urgently, better stick with version 6.20 for now.

(0005004) aaron 01-26-11 15:40	Thanks for looking into this! I'm checking out the Quercus src (svn://svn.caucho.com/resin/trunk/modules/quercus) [^] and perhaps I will be able to contribute towards this. Please let me know if there are any docs on Quercus/PHP extension implementation I should be looking at. It looks like each module supplies a class, named by convention, which implements the particular extension.

(0005005) domdorn 01-26-11 16:01	I pushed a basic mock implementation to https://github.com/quercus/quercus-filter [^] Still need to setup the test configuration, then we can start implementing it.

(0005020) wasay 02-03-11 16:00	I am very new in implementing Resin and I get this error Caucho\Resin\resin-4.0.14\webapps\drupal\includes\errors.inc:247: Notice: $_SESSION is an undefined variable [drupal_set_message] I just downloaded the resin like an hour ago and followed the installation and the hello world worked fine. Now the drupal installation is showing error and I don't want to go forward as I am not sure if there will be more errors. Please advice as to where I can find a solution; do I have to download some daily build to resolve this error? Please advice, Thanks.

(0005021) aaron 02-03-11 16:21	Hi wasay, are you using Drupal 7? It appears Drupal 7 (which is very new) is not yet fully supported. There are some newer PHP extensions which are used. Work has started on implementing these extensions (in the quercus-filter project on github noted in this issue). Until this is fully implemented I would advise using that last release of Drupal (6.20) which to my knowledge runs fine on Resin/Quercus.

(0005022) wasay 02-03-11 16:24	Okay, thanks aaron. I will use the previous release for now.

(0005475) timowest 08-29-11 01:41	Any chance to get all the Maven dependencies for quercus-filter to be available from the Quercus Maven repository?

(0005548) chx 10-06-11 21:53	Waste no time on implementing filter, it's trivial to reimplement the few things we use in userspace. Make sure PDO works. That's the challenge.

(0005902) nam 06-21-12 00:24	Fixed for 4.0.29. However, drupal_parse_info_format() needs to be patched in order for the install to work properly. It needs to return a completely new array. The underlying issue is PHP's reference counting, which Quercus does not support (Quercus instead uses the JVM's garbage collection).
