Very few lines of code to create the new node type and possibly assign a node title based on the file name. There is sample code in docs, but it is overcomplicated, since it does more work. I'm not sure if you won't be able to get away with mostly a custom .info file. Haven't looked carefully at d6 yet. If you base it around standard nodes, you don't need cck. views is automatic. Theming as well, unless you want a custom look, which is sightly more complicated, but quite straight forward. The docs team has done a good job, really. > >> That way files can be commented on, searched for and > >> can have notes on versions > > Only if you can extract text from the files.

You need something to extract them from your files - doc, pdf, whatever.... Drupal by default doesn't know anything but their name and size and that is not in the search table. I would be happy to update docs, but i will possibly have a week or so free(ish) towards the middle of July. Before that it is busy, busy, busy. If anyone wants to help out with the module or become a co-maintainer/maintainer, just shout. We can sync via email and irc. Cheers, Vlado

5/6: cache_clear_all(), custom items, and no cache_lifetime > failure
by Morbus Iff 23 Jun '08

23 Jun '08

Michelle ran into it long ago in her Advanced Forum module, and I ran into it a while back in regards to blocks. I just ran into it again today in a non-block scenario. In short: http://www.lullabot.com/articles/a_beginners_guide_to_caching_data will only work if you have a "Minimum cache lifetime" set. Cache expiration, for items with a custom expiration, will never automatically occur, as cache_clear_all('', 'cache') is never called. This happens in Drupal 5 and 6. There are three ways that cache can be expired: 1) you manually expire your own entry. 2) cache_clear_all() is called with the right parameters. 3) cache_get() is called, with a minimum cache_lifetime set. For now, let's safely ignore 1) since the explanation of cache_set() suggests that setting your own expiration timestamp treats the item as CACHE_TEMPORARY, and that it'll be flushed in the next general clear. Also ignore #3 - let's assume no minimum cache lifetime was set. If we take a look at cache_clear_all(): http://api.drupal.org/api/function/cache_clear_all/5 http://api.drupal.org/api/function/cache_clear_all/6 we can see the helpful comment of "No minimum cache lifetime, flush all temporary cache entries now." To get this code to run, however, the $cid must be empty *and $table must be set to 'cache'*. If both cid and table are empty, then the function defaults to clearing cache_block and cache_page. But, if you grep for "cache_clear_all()" in core, you'll never find an instance of "cache_clear_all(NULL, 'cache')". You'll see lots of "cache_clear_all()"s with no parameters, and lots of specific clearing, but nothing that specifically clears out temporary items in 'cache'. You won't even see a "destroy everything" cache_clear_all(*, 'cache', TRUE). I consider this a bug: * garbage collection should happen automatically - else, why would a calling module tell cache_set() about the expiry date if it's the module's responsibility to clean it up? * "Minimum cache lifetime" is a performance tweak, and should not be required to properly clear CACHE_TEMPORARY items. How to fix the bug? Honestly, I don't know - one would, presumably, add a cache_clear_all(NULL, 'cache') to a hook_cron implementation, but I'm not the one to know the best location for that. Suggestions? And, naturally, if my reasoning is all wrong, lemme know too. -- Morbus Iff ( if god is my witness, god must be blind ) Technical: http://www.oreillynet.com/pub/au/779 Enjoy: http://www.disobey.com/ and http://www.videounderbelly.com/ aim: akaMorbus / skype: morbusiff / icq: 2927491 / jabber.org: morbus

Re: [development] module_exists vs. functions_exists?

Ah, thanks. Keeping it simple... ----- Original Message ----- From: "Daniel F. Kudwien" <news(a)unleashedmind.com> To: development(a)drupal.org Sent: Monday, June 23, 2008 8:53:52 AM GMT -05:00 US/Canada Eastern Subject: Re: [development] module_exists vs. functions_exists? > $foo = module_invoke('module_name', 'api_function', $bar); ...without module_exists() is sufficient. module_invoke() invokes module_hook(), which in turn checks for function_exists(). Also, module_invoke() is not limited to Drupal hooks / API callbacks. If the returned results of call_user_func_array() work for your particular implementation, this is the best approach for each module that wants to integrate with another, optionally installed module in contrib. @see http://api.drupal.org/api/function/module_invoke/5 @see http://api.drupal.org/api/function/module_hook/5 Daniel

DrupalCon Szeged registration

I had to share this: I just completed my DrupalCon Szeged registration. The conference organization and the registration system on the website are truly remarkable. Keep up the great work! (If you haven't registered yet for DrupalCon Szeged, now is the time as the conference will become more expensive at the end of the week.) -- Dries Buytaert :: http://buytaert.net

Is it possible to serialize the output of a custom block and unserialize the value in a page.tpl.php ?
by Juan Rodriguez 18 Jun '08

18 Jun '08

Hello, I am trying to serialize the output of a block, which is received in a page.tpl with the $content variable. It seems it does not work, but I don't know why, because I can output the serialized string (using $content) in a page.tpl.php file but if I try to unserialize it and afterwards try to print_r the result, it shows nothing. Does anybody have any clue? It seems quite weird to me...

Help with hook_search
by Ron Parker 17 Jun '08

17 Jun '08

I just submitted an issue here: http://drupal.org/node/271604. The Drupal 5.x and 6.x hook_search documentation is incorrect. I just want to add another tab to the search form that, for right now, just does another regular search. Not specialized in any way (at least right now). Just a normal search, but the api documentation is incorrect and I can't find any examples anywhere of how to do this. Can someone point me in the right direction, or show me the hook_search api code that *does* work? Thanks! -ron -- Ron Parker Software Creations http://www.scbbs.com Self-Administration Web Site http://saw.scbbs.com SDSS Subscription Mgmt Service http://sdss.scbbs.com Central Ave Dance Ensemble http://www.centralavedance.com R & B Salsa http://www.randbsalsa.com
