I haven't read all the comments, but it seems like abstracting the core SimpleTest browser may be of interest to you. The code is quite far along and details can be seen http://drupal.org/node/366978. My plan was to port the code back to Drupal 6 as a module which seems like it might be useful for you. Jimmy

SQLite and Drupal 7 -- third coming
by Karoly Negyesi 05 Feb '09

05 Feb '09

Hi, Every morning, I am distilling the discussion. *) SQLite is not supported. If you have Drupal 5.2 and PDO which are already requirements then you have SQLite unless it's explicitly disabled and so far noone was able to answer the challenge at http://drupal4hu.com/node/177 . It's embedded into PHP so "supporting" it is like supporting the SimpleXML extension. Unlike MySQL where you need to run a separate server, here we have an embedded SQL engine right inside PDO. Also note that if we want (and I think we want) easier and more powerful install profiles then we will require SQLite for the install anyways. *) Deployment and rebuild. As it stands, now I believe that Drupal should be able to boot up enough to be able to copy the tables from MySQL to SQLite. I am not saying I am expecting it to be functional. After the tables are copied back into SQLite, it should either restart the bootstrap process or reload at the same URL. This solves deployment. *) Why do I want this? Once again, nicer code, especially for caching. Various pluggable subsystems (cache, session and path being the biggest wins here) will just work instead of ugly hacking. But in general, instead of trying to figure out during bootstrap coding "do we have a DB connection yet" the answer is always yes. Kind regards NK

This may be easiest to do with XMLRPC. See http://drupal.org/node/82114.

url as callback argument
by cooper Quintin 04 Feb '09

04 Feb '09

Hello all, I am writing a module and I am trying to use a url as a callback argument, but it does not work. Here is the code: $items[] = array( 'path' => 'admin/settings/featured-comments/feature', 'title' => t('featured comment'), 'callback' => 'feature_comment', 'callback_args' => $_GET['cid'], 'access' => user_access('administer comments'), 'type' => MENU_CALLBACK ); and the callback function: function feature_comment($cid) { $comment = _comment_load($cid); db_query("UPDATE {featured_comments} SET featured=1 WHERE cid=%d", $cid); drupal_goto("node/$comment->nid"); } going to an example url: http://example.com/admin/settings/featured-comments/feature?cid=10840 gives the following error: warning: Missing argument 1 for feature_comment() in /var/www/html/sites/all/modules/featured_comments/featured_comments.module on line 149. So my question is, what is the best way to use parts of the linked url as a callback argument for a function, because obviously it is not what I am doing!

SQLite and Drupal 7 -- let's try this again
by Karoly Negyesi 04 Feb '09

04 Feb '09

Hi, Apparently despite my intentions, I did not manage to express myself clearly so let's try this again. Drupal 7 has a very interesting new feature which we call the registry. The registry holds information about which function, class and interface lives in which file. This information never changes if you do not change your modules and themes. Drupal always had a system table which holds information on available themes and modules. This information never changes if you do not add new modules nor new themes. If we put these tables in an SQLite table then the only time this file changes is when your code changes. Therefore, when people with high performance sites deploy their new code, they can deploy the new database. There is no new procedure to be created, just one more file added to the roster. Now, if I ask this way, are people still against putting registry and system into an SQLite database? NK

Drupal API Page with Comments?
by Margie Roswell 04 Feb '09

04 Feb '09

Hi, I think it would be enormously helpful to drupal users if a core and contributed modules API site enabled comments. Something like this: http://us.php.net/manual/en/function.is-array.php Is there any reason this couldn't be done? Throwing the idea out there. Is this the right place to post this idea, or is it better discussed somewhere else? Any technical or social reasons we shouldn't do this? I think it would expose so much helpful code to struggling drupalers! There's always wheat and chaff, but people are pretty good at sorting out that stuff. For now, it's tough climbing the learning Drupal learning curve without an annotated functions page like the one on the PHP site. BTW, I'm a huge fan of the contributed module API site at http://api.freestylesystems.co.uk/ Best Regards, Margie

Drupal Module
by Kesavan, Prakash C 04 Feb '09

04 Feb '09

Hi , I was trying to implement a question bank , A customer need to choose questions from the bank for different streams like mysql,php,rhcs etc...and fill the mandatory part of it ,also they may need to add additional questions if they want and submit. I was tiring to do so with webform but I think it doesn't support to call from question bank. It just creates the multiple questions. I tried with taxonomy also but I could not integrate with the same and it doesn't work for me.. If there is any other module currently present ,it would be grate for me. or some help for how to create a module. I am new to Drupal. It will be grate if somebody provide me good document for developing a drupal module which came out of there real experience. +hp=everything is possible Thanks In Advance PrakashCKesavan RHCE,OCA,CSA Technology Consultant OpenSource And Linux HP GDAS +91 9972047746

node type not listed at node/add
by augustin (beginner) 04 Feb '09

04 Feb '09

Hello, With a module implementing its own node type, the said node type is not listed at node/add. Is this a feature or a bug? http://drupal.org/node/368924 Everywhere, it is said that the menu item is automatically created from hook_node_info() but having read the documentation and followed the tutorials, it just doesn't work for me. Thanks, Augustin.

SQLite and Drupal 7
by Karoly Negyesi 04 Feb '09

04 Feb '09

Hi, In case you do not know, SQLite is a one-file database which Drupal 7 supports. One thing we can do, and this is easy, to ship with Drupal install in a read-only SQLite database, say, in the Drupal root. This would allow install.php to become much cleaner and also make install profiles pretty much regular modules with an access to the whole Drupal system. This will make Drupal require SQLite, but I ran a poll, I ran a challenge and seemingly every site that has PHP 5.2 and PDO has SQLite as well. Now, there is more. We could SQLite as a sort of SQL cache. We could put the following tables into SQLite: a) system b) registry* c) menu_router d) variables e) some cache tables (caution: SQLite is not that good at concurrent writing. It works but only up to a certain point as it locks the whole database.) f) any other table that's read often and written not-so-often. The first two needs some security hardening but that's ongoing. The advantages are somewhat clear: very very early we have access to these things, in a standard, smooth SQL accessible way. On, say, registry rebuild or module enable, DBTNG could easily copy the relevant table from MySQL. There is a disadvantage, however on every site that uses multiple webfrontends against the same MySQL database. There are two kinds of these, high performance sites and development sites. Development sites can put the SQLite database on a network share -- this is neither performant nor safe because both Unix and Windows has bugs with shared FS file locks. But, it will do for development. We could say that for high performance sites you only change system or the registry when you deploy and thus the SQLite file is just one more to be deployed. Otherwise you will end up with a bad situation, where the frontend that handled the rebuild will have its SQLite databases properly updated while others wont. Of course, there are other ways. We can store a "table version number" in a MySQL table for the tables that sit in SQLite and on every request compare and if necessary, copy the table from MySQL to SQLite. if we happen to have a setup where you can serve cached pages from SQlite without touching MySQL then there might be a slight lag with this method. Questions are 1) Are we OK with making Drupal rely on SQLite for every request? 2) Do we want "deploy your SQLite table and be done"? 3) Do we want table versions? 4) Should I just shut up and go back into my corner?
