[drupal-devel] 4.5.2 Image module, PHP exec, SELinux problems
by Djun Kim 18 Apr '05

18 Apr '05

Hello all, is anyone else running Drupal on Fedora FC3 or any other system implementing targeted policy for Security Enhanced Linux? I'm having the following issue: image module execs the convert binary from the imagemagick package. Because this call passes command line arguments, PHP execs bash to process the command. The default SELinux policy does not allow httpd to execute bash, and I don't particularly want to open exec permissions on bash to anything run from httpd. Has anyone found a reasonable compromise for this situation? -- puregin(a)puregin.org http://www.puregin.org

[drupal-devel] [feature] Improve functionality of block generation for book module
by bomarmonk 18 Apr '05

18 Apr '05

Issue status update for http://drupal.org/node/14120 Project: Drupal Version: cvs Component: book.module Category: feature requests Priority: normal Assigned to: andremolnar Reported by: nysus Updated by: bomarmonk Status: patch This functionality seems crucial to completing the organizational website that I have developed with Drupal. Yet, I've applied the book.module and menu.inc patches to Drupal 4.6 and can't seem to get by book blocks to display on the front page. Why not? Is it because I'm using the front_page.module? I'm still using a themed drupal page for the front page. I definitely need help with this. bomarmonk Previous comments: ------------------------------------------------------------------------ December 9, 2004 - 06:12 : nysus Attachment: http://drupal.org/files/issues/book_19.patch (4.85 KB) Attached is a patch for the book module that does the following: 1) Allows book blocks to appear on any page at any time, not just when a node from the book is being viewed. 2) Allows multiple book blocks to appear on the same page. This functionality is achieved by the automatic creation of individual blocks for each book when the book is created. Simply enable the book's block to enjoy the benefits of 1 & 2 above. If the blocks are not enabled, the blocks will appear only when a node from that block is being viewed (the same way it works now). ------------------------------------------------------------------------ December 9, 2004 - 12:35 : andremolnar Attachment: http://drupal.org/files/issues/book_19_1.patch (4.84 KB) +1 This is great. A good many people have asked for something like this, and I think its a nice solution. But in the end this isn't up to me. One minor error in the patch... + $result = db_query('SELECT n.title, b.block, b.nid FROM {book} b INNER JOIN {node} n on n.nid = b.nid WHERE b.parent = 0'); b.block is not a valid field in this query. this updated patch removes reference to it. andre ------------------------------------------------------------------------ December 9, 2004 - 13:54 : nysus Glad you like it and thanks for fixing that up. It was left over from an older version of my patch. ------------------------------------------------------------------------ December 9, 2004 - 13:54 : andremolnar Steve, If I apply this patch, and I attempt to configure one of the newly created blocks. I noticed that for some reason the block.module is returning "true" at line 249 (of the block module)- and is creating a form for module-specific configuration. But all that shows up on the screen is the word "array". Can you trace this back to see why - and maybe update the patch. I can continue to test your changes - anything to help this patch make it into core. andre ------------------------------------------------------------------------ December 9, 2004 - 15:29 : nysus Hmmm...probably because I tested my patch on my version of Drupal, version 4.5.1. I'm having no problems. Are you using a cvs version of Drupal to test. If so, I'll set up cvs on my site and track this down. ------------------------------------------------------------------------ December 9, 2004 - 18:53 : drumm See http://drupal.org/node/12347 for information on how the block system has been updated. When I saw that the elseif ($op == 'view') was taken out I knew immedaitely that there was something weird about this patch. ------------------------------------------------------------------------ December 9, 2004 - 18:58 : nysus OK, thanks for the tip. Sorry for the confusion. Still kind of new to making open source contributions and it's easy for me to overlook some obvious stuff like this. I'll fix this up when I get a chance. ------------------------------------------------------------------------ December 9, 2004 - 19:06 : Dries Please do, because this being a new feature, it has no chance getting committed to the DRUPAL-4-5 branch. The DRUPAL-4-5 branch is in bugfix-mode. New features go into CVS HEAD. ------------------------------------------------------------------------ December 9, 2004 - 22:32 : Dries There is quite a bit of duplicated code in the patch. Maybe it can be simplified (using a function)? Either way, it is a little weird. I haven't tried the path, and I'm not sure I understood the description. It's somewhat vague. Is the book module exporting multiple blocks that are nearly identical, yet have different display behavior? If so, why not add a simple block configuration setting to the original book block? ------------------------------------------------------------------------ December 10, 2004 - 02:51 : nysus Dries, Yes, there is some code that can be factored out and some general cleaning up that can be done. It was a little tricky to write so I left it kind of ragged around the edges until I'm sure there are no bugs. It has worked very well on 4.5.1 but I obviously need to update it to work with cvs. I'll be on that soon. As far as what it does: 1) For every new book that a user creates, a new block is associated with it. So if you create "Book A", "Book B", "Book C", you will get three new blocks visible on the block administration page called "Book A", "Book B", "Book C". The original "Book Navigation" block is still there, too. The functionality of the "Book Navigation" block is not affected at all by this patch. 2) If Book A's block is enabled, the block containing its menu will appear not only when a node within Book A is viewed, but at all times (unless the user suppresses it on certain pages with the "path" feature). When any node is that is NOT in Book A is viewed, Book A's menu still appears but it is fully collapsed. When a node that DOES belong to Book A is viewed, Book A's Book menu expands accordingly. 3) The user can also enable Book B & C's block, and have their menus appear in a block at all times as well. 4) If none of the book's blocks are enabled by the user, the module will behave just as it did without the patch. That is, when the "Book Navigation" block is enabled, the only time any book menu will appear is when a book node is being viewed. 5) It's important to note (and this was the tricky part to write) that if both the "Book Navigation" block is enabled and "Book A" is enabled, they will play nice with each other and not do nasty things like create the same book menu twice. ------------------------------------------------------------------------ December 10, 2004 - 05:51 : nysus Attachment: http://drupal.org/files/issues/book_20.patch (5.37 KB) Andre, Attached is a new patch that will resolve the problem of the block-specific stuff showing on the block configuration form. Let me know if you spot any other bugs. If it looks good to you, I'll go to work making the code look leaner and prettier. ------------------------------------------------------------------------ December 10, 2004 - 07:26 : nysus Attachment: http://drupal.org/files/issues/book_21.patch (4 KB) Dries, Andre: Here is a new and improved streamlined version of the patch. Have a look if you get a chance. ------------------------------------------------------------------------ December 10, 2004 - 08:11 : nysus Attachment: http://drupal.org/files/issues/book_22.patch (4.15 KB) Found a bug in the last version that would cause the block to jump to a different location. I think this should do it. Everything appear to work well (famous last words). ------------------------------------------------------------------------ December 10, 2004 - 14:49 : andremolnar Steve: bugs appear to be gone, and I didn't run across any other errors. This is functioning exactly as described. everyone: I personally would encourage support for this functionality. Book is a powerful navigation building tool in a site, not only with its ability to move next and back through a hierarchy of pages - but also its ability to build the appropriate navigation block without further user intervention (unlike the admin features in the menu module or taxonomy). The most frequently cited complaint about the book module is its inflexibility when it comes to when and where the block shows up. I also frequently hear requests for the ability to show multiple book blocks at the same time. Up until now the best alternatives suggested required users to do a hack (e.g. build a custom block that calls such and such a hook). Most abandon their request at that point because its over their heads. With this patch all those requests are covered and more. Now all books can automatically have their own block and admins can easily decide when and where each of those individual blocks show up (left right, up down) and coupled with the new configuration features of the block module - its very easy for admins to decide on which individual pages a block will show up. I would be interested what other have to say about this feature. My only reservation (which is minor compared to the benefits of the functionality offered) is that there is no way to turn this functionality off. i.e. The default behaviour is to build individual blocks for each book. If there could be a way to toggle this feature on and off somewhere - it would be perfect. Still, AS IS - this is a major improvement and offers great flexibility to admins and site creators. andre ------------------------------------------------------------------------ December 10, 2004 - 15:04 : Anonymous Andre, Thanks for the feedback on the usefulness of this module. Glad I could pitch in and help. I agree about the inability to turn the feature on/off and I was thinking about that myself. I think it could easily be accomplished by creating a checkbox in the "book navigation" block individual configuration's settings. Call it "Enable individual book blocks." When enabled, the individual book blocks will appear on the block administration menu. One question: Where would the state of this checkbox get saved? Has Drupal moved away from serializing data in the data base? ------------------------------------------------------------------------ December 10, 2004 - 18:36 : Dries I'm afraid that 'Enable individual book blocks.' is not descriptive/clear at all. Are you suggesting a setting to toggle between 'show block on all pages' and 'show block on book pages only'? ------------------------------------------------------------------------ December 10, 2004 - 19:45 : nysus Dries, No. Andre and I suggest a setting within the "Book Navigation" cofiguration page, that would toggle whether or not individual books appear on the list of all blocks on the block administration page. Hence the name 'Enable individual book navigation blocks.' The help text for this checkbox might read something like: "By default, a book's navigation block is visible only when a page from that book is being viewed. Check this box if you want more control over where and when an book's navigation block is visible. You will then be able to control the book's navigation block location and visibility settings on the "admin/block" page." Hope this makes it pretty clear. ------------------------------------------------------------------------ December 10, 2004 - 20:08 : Dries I understand what you are trying to do, but not how you are trying to do it, or how the setting is supposed to work. I guess I'll have to try it when a new patch lands. ------------------------------------------------------------------------ December 11, 2004 - 09:52 : nysus Attachment: http://drupal.org/files/issues/book_23.patch (5.02 KB) Alright, fellas, I'm proud to unveil my crowning achievement in the open source development world (no big deal to most of you guys but pretty good for a hack like me). Thanks for all the input so far. It's been helpful. I've streamlined the heck out of it per Dries suggestion and I've created an option to turn this functionality on an off per Andre's suggestion. Does this look good to you guys? Anything else I have to fix or improve? Thanks. ------------------------------------------------------------------------ December 11, 2004 - 13:02 : Dries I tried the patch. It works great but to me, the 'Give books their own block' settings seems to be redundant. Why not export the current book navigation block, along with an additional block for each book? Looks a lot simpler to me. I think I spotted a bug: orphaned book pages (or possibly book pages that are unpublished) appear to be getting book navigation blocks. ------------------------------------------------------------------------ December 11, 2004 - 17:34 : nysus I'll see if I can fix the bug. Might be tricky. But I don't understand your recommendation to "export the current book navigation block, along with an additional block for each book". Can you expand on this thought? ------------------------------------------------------------------------ December 11, 2004 - 18:06 : nysus Dries, I am unable to duplicate the bug. I have three orphaned pages. I also tried unpublishing some pages. But as far as I can tell, the patch works as expected. ------------------------------------------------------------------------ December 11, 2004 - 19:00 : Dries If you can't reproduce the problem, chances are my node/book table is somewhat fubar. As for the configuration option. I suggest removing it and to always make these new blocks available on the /admin/block configuration screen. ------------------------------------------------------------------------ December 11, 2004 - 19:52 : moshe weitzman I am hoping that we maintain the option to keep the behavior where the appropriate book block only shows up when its book page viewed. this is a nice, tidy arrangement. ------------------------------------------------------------------------ December 11, 2004 - 20:03 : nysus Yes, if you don't enable any of the individual book blocks, the a book's block (i.e. navigation menu) will only appear when a page in a book is viewed. In other words, you have the option to have the book block act like this patch isn't even installed. ------------------------------------------------------------------------ December 11, 2004 - 20:54 : Dries I guess I'll have to try the patch again, because I don't understand why it works like this -- or at least, why it can't be made simpler. ------------------------------------------------------------------------ December 11, 2004 - 21:13 : nysus Can you be more specific? Why it works like what? ------------------------------------------------------------------------ December 11, 2004 - 21:24 : nysus Attachment: http://drupal.org/files/issues/book_24.patch (4.1 KB) This patch reverses a change made in the last patch which required a user to enable individual book block before they could enable any individual book blocks. ------------------------------------------------------------------------ December 11, 2004 - 21:41 : andremolnar As I mentioned earlier I am *fine* with either version of this patch as long as it makes it to core. But, as I said earlier, I clearly think the preference for admins would be to have the option to enable or disable this functionality. BTW - if this does make it in, I would be happy to create a Handbook page that describes the new features - something like "how to build robust site navigation using the book module". (on or after December 17th). andre ------------------------------------------------------------------------ December 12, 2004 - 12:11 : Anonymous I am not at all happy with these features. They are incosistant, confusing and should use exising methods and UIs. May main concern is the incosistancy: it is confusing, will require extra attention with each core code change, adds extra logic to the core, and is not re-useable. so here are my questions: 1) why do we not use the menu system and apis to build and adminster the trees? Saves code, does not add extra UIs, and gives users more power. 2) why do we need that extra showing logic? a book block should not get exeptional if clauses, it should use the existing path setting methods on block admin. extra logic is confusing for administrators (hey, i set the path so that the book-block should show up here, but it does not, why?) we should really not provide extra logic in the block hook, but should rather use default settings in block admin (the book could fill the bookblock sql cells with custom paths, for example) 3) we should avoid extra UIs. We already have far too much, and far too much different ones. Please rather improve the block admin, than add new separate interfaces. 4) why do book blocks need al these expeptions in the first place? If they are so exeptional, we could consider not using blocks, but something else, like in-line book layout (pages with the index etc) 5) why did you not choose for a general, standard, block gerneation API? that way modules, such as taxonomy, image gallery, weblinks, article, etc can reuse it and introduce block gernation. All that sayd, i like the idea of this functionality, but i fear for a great useability downfall if we start introducing all sorts of exeptions for all sorts of modules. Because now chances are very big that taxonomy, image gallery etc will need to introduce other UIs, other code, new methods and new documentation, if they too want some sort of better block handling. so a -1 from me. ------------------------------------------------------------------------ December 12, 2004 - 12:12 : Bèr Kessels ^^--- That was me (bèr kessels) forgot to log in..... ------------------------------------------------------------------------ December 12, 2004 - 12:34 : nysus I'm not going to pretend I can argue if my patch does or does not fit well into Drupal's larger architecture. My motivation for writing it is that I had an immediate need to create an easy way to make it easy for users to create menus. I'll let others decide whether or not the patch has merit from the big picture perspective. But if it doesn't, why not just use it for its immediate benefits and then throw it away when something better comes along? ------------------------------------------------------------------------ December 12, 2004 - 13:01 : Dries My summary is this: +1 on the functionality, -1 on the implementation. The code itself is good, but the usability/integration is not. ------------------------------------------------------------------------ December 12, 2004 - 13:13 : nysus When you say "usability" is that from the user's perspective or the code maintainers? I'm guessing it's the latter but I'm unsure. What about the idea of using the patch until a more permanent solution comes along? Yes, it's much better to live in a home with indoor plumbing but why not use the outhouse while you wait for a toilet to get installed? Or are there other considerations I'm overlooking that would make this a bad idea? ------------------------------------------------------------------------ December 12, 2004 - 13:20 : Goba nysus it is just generally against the Drupal philosophy to add improperly implemented functionality until something better comes along. There even used to be ocassions in Drupal releases, when some functionality was removed (not fixed) for a release, because its implementation was not adequate. ------------------------------------------------------------------------ December 12, 2004 - 13:55 : Dries Usability for the user. The extra setting on the block configuration page is both confusing and awkward. I don't understand why things must be configured/enabled that way (see my and Ber's previous comments on this issue). ------------------------------------------------------------------------ December 12, 2004 - 14:03 : nysus Well, just for the record, I reversed that functionality per your suggestion and uploaded the patch. The indiviudal book blocks now appear automatically. ------------------------------------------------------------------------ December 13, 2004 - 13:56 : Bèr Kessels Hi, I am sure you can make not only simpler, but better usefull for admins and users. All you need to do is use the menus for this. i.e. make a menu entry for each book page. For each book make a menu on level 0, without a parent. that way they become a seoprate menu, each with an own block. it saves code, makes things more consistent, and most important, uses drupal functionality where it should. ------------------------------------------------------------------------ December 13, 2004 - 14:50 : nysus Ber, Are you suggesting that for every single book page that a menu item be created? That's really not practical. That was my main motivation for writing this patch: to make it easy to put links, not necessarily related to one another, into a block. Any more pages than 10 and the sheer tedium of the job would prevent anyone from ever doing that. The menu.module is great, but adding new menu items is far from quick and painless. I just added about 10 to my menu for different taxonomies on my site and it wasn't fun. Plus, if you do as you suggest, there is also the problem of the book showing up twice. It will be generated by the menu and then it will be generated again by the book module which is programmed to design a block. You'd have to put some logic in the book.module _block hook to try to anticipate if a user has enabled a book in the menu. That wouldn't be pretty code. I'm all for putting automatic generation of book navigation blocks as part of the menu module. It does make more sense to have it there. But it forces me to ask the question: "Then why do we currently have code in the book module that generates a menu? Shouldn't that belong in the menu.module, too?" ------------------------------------------------------------------------ December 13, 2004 - 22:31 : killes(a)www.drop.org I think what Ber is trying to say is that you can write a contrib module that monitors the changes to the book table and creates menu items automatically. nodeapi is your friend. I would also prefer this solution. ------------------------------------------------------------------------ December 15, 2004 - 16:39 : Anonymous ""Then why do we currently have code in the book module that generates a menu? Shouldn't that belong in the menu.module, too?" " Because it's old code. It would be nice if book.module generated this block using its _menu hook, so that the admin would have a few options in terms of configuration. "Plus, if you do as you suggest, there is also the problem of the book showing up twice. It will be generated by the menu and then it will be generated again by the book module which is programmed to design a block. " No. The old code which manually builds a block in book.module would be removed. Book blocks would only be generated by the menu. This would also have the added benefit of allow the administrator to easily place a book in an appropriate spot in the menu tree, while still allowing the possibility of displaying it in a separate block. Because of menu caching, I don't expect a large performance hit for creating the menu items. "That was my main motivation for writing this patch: to make it easy to put links, not necessarily related to one another, into a block. " It sounds like instead of (mis)using book.module, your time would be better spent in a usability improvement to menu.module so it's easier to do this. ------------------------------------------------------------------------ December 16, 2004 - 06:55 : nysus Thanks for the feedback and input. I appreciate it. However, I would also appreciate if you took more care to avoid the condescending tone in your post: "It sounds like instead of (mis)using book.module, your time would be better spent in a usability improvement to menu.module so it's easier to do this. " It's really quite unnecessary and off-putting. Though it won't stop me from contributing to Drupal in the future, I'm sure others would be really turned off by such a patronizing comment and it could dissuade them. I'd like the Drupal community to be a welcoming and friendly place that will inspire people to contribute, not discourage them. Thanks. ------------------------------------------------------------------------ December 16, 2004 - 10:07 : Bèr Kessels nyesus, Please do not start /that/ discussion here. :) Drupal community is known fo being direct, maybe because of the big number of western-Europeans attending, maybe because of other reasons. No-one commented that you are wasting your time. But the commentor was telling you somthing likethis: "If you would follow the previous sugeestions, your added feature would be much better appreciated, and will probably work much better for you too". He/she was by no means telling you to stop your silly coding, or anything in that line. He/She only wanted to show you the obvious and better direction. We often deal with issues that add some feature, and a complete new UI, because the author does not like, or cannot use the existing UIs and features. This is nogt good, because if that same author would have spend his/her time on improving that existing functionality or UI (improving is not neccesarily the same as extending!!) that code and time would benefit all much better. Thats what the commentor tried to say. And so is it here: If you dislike the way the books handle the blocks, and if you do not want to use the menu, because you do not like its UI, then do not add another UI and more features, but rather merge these, and improve the parts (in the menu) you dislike. ------------------------------------------------------------------------ December 16, 2004 - 10:35 : Dries We can worry about the menu integration later. Let's focus on the new option's usability/interaction design first. ------------------------------------------------------------------------ December 16, 2004 - 14:51 : nysus I understand what the commenter was saying and like I said, I appreciate and understand it. I'm not upset and I'm not looking for an argument, I was just being direct as well. :) As part of the Drupal community (albeit a minor player), all I'm saying is that I would like to see folks not have a tin ear to the humanity in all of us. It will help make Drupal an even stronger community and attract even more talented developers. Human interaction is part of the development process. Whether we like it or not, we must cope and deal with it. ------------------------------------------------------------------------ December 18, 2004 - 09:54 : Dries I thought some more about this and am starting to believe that integration with the menu system should take priority. Here are common cool scenario's: I want to create a separate navigation block for the 'Drupal handbook'. I want to add a menu item called 'handbook' to the user block. That is, I want the book navigation to be part of the existing user navigation block. I want to add a menu item called 'handbook' to the top-level navigation menu. How would that work from a user's point of view? What do I have to click and where to configure this? ------------------------------------------------------------------------ December 21, 2004 - 18:47 : andremolnar I was actually thinking about the same thing last night (must have been something in the arctic air). / 2. I want to add a menu item called 'handbook' to the user block. That is, I want the book navigation to be part of the existing user navigation block. 3. I want to add a menu item called 'handbook' to the top-level navigation menu. / This is already possible (to a certain extent) with the current Book.module and Menu.module - A 'Books' menu item is created in the user navigation by having the Book.module enabled. Menu.module allows you to enable/disable this menu item. Menu.module also allows you to re-name this menu item. But, this only helps if you only intend to have 1 book (or else the name 'Handbook' is misleading if the user finds more than 1 book listed). - so this isn't good enough (or is it). /1. I want to create a separate navigation block for the 'Drupal handbook'./ This is what I was trying to figure out. Not just this, but a different way to do what Nysus was attempting. i.e. create a menu block for each and every book that is created. There is a way to write code that would (re)build a 'custom menu' on every add/edit/update to a book page - or book outline update. Custom menu's automatically have a block created for them. But, this I think would be a misleading use of the 'custom' menu - as the menu would not be custom if they are a part of core. So, I would think that two new constants could be added to the menu.inc file - MENU_BOOK_MENU - and MENU_BOOK_ITEM - each would behave as custom menu's, but would be reserved for books. These menu types should NOT show up in the Menu.module administration - because the administration of the book_menu items would be done by administering the book itself (adding an item, removing an item, moving an item up/down in the hierarchy, assigning parents etc.). However, the blocks that the book_menus would create would show up in the block administration (so users could enable/disable each block - and decide where on the site they show up). The existing book block logic would be removed. So the logic would be: If a creates a book in the book administration page - the Book.module automatically creates a new MENU_BOOK_MENU Any time a user adds to or updates or delets a book page - the entire book menu is deleted and recreated based on the hierarchy defined by the book itself. The blocks for each book would show up in block administration. Any thoughts - I know that this doesn't exactly address points 1 and 2 - but it could act as a first step. Is this approach a bad idea? It would add special conditions for the proposed book menu's - but books would be a special case. Even if people don't like this solution, maybe it will give someone a better idea. I'd love to hear them. andre ------------------------------------------------------------------------ December 21, 2004 - 22:55 : Boris Mann +1 to this andre I had promised to put down my thoughts on this matter, as it relates to 1) primary and secondary links and how they are managed and 2) auto-generation of primary/secondary navigation based on book outlines So, for 1), we currently have functional-but-not-very-usable plain textfields to manage primary and secondary links. I would like to see menu.module used to control all navigation links, whether it is the navigation block or primary/secondary links. What is needed: a) default system menus labelled "primary" and "secondary" which would store; this is where modules could insert navigation b) support for full URLs (e.g. http://myexternaldomain.com) instead of just path 2) if we got 1 working, and andre does his book menus, this could get taken care of automatically. Basically, for brochureware/business/etc. sites that have static content, you could have a root book as one of the primary navigation links, and then the secondary links are generated automatically. ------------------------------------------------------------------------ December 22, 2004 - 21:02 : Dries I agree with Andre that the book module's integration with the menu system needs to be worked on. I support any effort that makes it easier to structure pages and that makes it easy to link pages/nodes from within a menu. However, I'm opposed to putting book module specific names in the menu system (eg. MENU_BOOK_MENU and MENU_BOOK_ITEM). I can imagine a handful of modules that want to maintain a menu tree (or part thereof) so I'm in favor of generic names. I'd have to read up on the menu system code, but last time I checked there was a MENU_MODIFIABLE_BY_ADMIN flag. You could choose not to set this flag for the menu items generated by the book module. Maybe it's already possible to implement to implement Andre's suggestion without having to modify/extend the menu system. Are you exploring this path? ------------------------------------------------------------------------ December 24, 2004 - 10:01 : andremolnar I've had a few spare hours to work on this. I've started to cobble together a solution - but in doing so I discovered a bug in the menu module (for which I will submit a seperate issue - if one doesn't already exist). The principal I suggested works. I added some code to the book module that creates custom menu's (MENU_CUSTOM_MENU with MENU_CUSTOM_ITEMs) for each Book that exists in a site. This is just as a proof of concept - I chose this menu type to start with because they automatically have a block created for them in admin/block (which is ultimatly the functionality we want). I ran a test and the menus are created as expected - the blocks are also created. But when I tested the menu blocks by enabling them I ran into a problem. It seems as though the menu system does not expand/explode sub menu items if the node type is book. I'm not sure why this is, and I haven't traced the source code yet - I thought I would ask if anyone has intimate knowledge of the menu system if they can point me in the right direction. No patch attached because until that problem is fixed this proposed change won't fly :( andre ------------------------------------------------------------------------ December 24, 2004 - 11:11 : Dries Just a wild guess: maybe it doesn't work because the book module's URI scheme is not hierarchical? ------------------------------------------------------------------------ January 7, 2005 - 10:45 : andremolnar Attachment: http://drupal.org/files/issues/book_module_1.patch (5.1 KB) I finally took some time out to do some work on this. As mentioned in a post to dev the problem I was having with menus not expanding/contracting properly was some crud in my database. Once that was cleared up my changes worked fine. I am attaching a patch for comments and for the brave willing to give it a test drive. History: This thread and http://drupal.org/node/15198 and http://drupal.org/node/15153 node/15198 has a patch that is required for this patch to work. What this does: Pretty straight forward. Any time a user adds/updates/deletes book or book pages (including via outline) - a function is called to create a new menu for each book. Any existing book menus are wiped out and then the new book menus are inserted - and the system menu is rebuilt to reflect the changes. The menus created consist of type MENU_MODULE_MENU and MENU_MODULE_ITEM. These menus show up in the menu/admin page so that admins can be aware of them, but the menu types are not editable via menu/admin (all changes are handled by the book module). Since the menus are in the menu table, the menu_block() hook handles the creation of the blocks for each of them. The blocks can then be administered in the usual ways via the block/admin interface. KNOWN ISSUE: (suggested solutions welcome) Since the menu table is updated on every change to books - the blocks associated with the menus are also recreated with default settings (i.e. disabled, and with no path or throttle settings) requiring a user to take an extra step and re-configure the book blocks for viewing on their site. I think this is unacceptable. For the casual user of the book module that only has a single book that doesn't change often, this would not be a big deal. But, if anyone wanted to make use of book module to handle dynamic site navigation this would create more work than it saves. Looking forward: If the block generation issue can be solved in a tidy way, this patch could allow users to use book to handle all their site navigation generation needs. Also, this patch could allow for the removal of a large chunk of code in the book module dedicated to building its own block via the block system. I left it there for now because I suppose there may be those out there that want to have book.module work the way book.module always worked (only show the book block when viewing a book page). Even so, since each book would have its own block, an admin could specify when and where the block shows via admin/block. I would appreciate feedback. If nothing else I hope this gives someone some new ideas. I'll continue to work on the block regeneration issue. andre ------------------------------------------------------------------------ January 7, 2005 - 10:47 : andremolnar Attachment: http://drupal.org/files/issues/book_module_2.patch (4.98 KB) sorry - here's a patch with prefered line breaks. andre ------------------------------------------------------------------------ January 7, 2005 - 16:47 : nysus Andre, I've been meaning to give this a throrough look when I get a chance. Hopefully this weekend. ---Steve ------------------------------------------------------------------------ January 20, 2005 - 02:02 : andremolnar Attachment: http://drupal.org/files/issues/book_module_3.patch (6.66 KB) Here is an updated patch. Same comments as followup 51 - except that the known issue has been resolved. This changes book module so that any action taken on a book, including adding new books or book pages will create a menu in the menu system for that book - and thus create blocks for those menus that can be administered in the usual ways. This is my first attempt at a major patch to core - comments are welcome I will be happy to update documentation once revisions to the code have been taken care of. andre ------------------------------------------------------------------------ January 20, 2005 - 02:53 : andremolnar Attachment: http://drupal.org/files/issues/book_module_4.patch (6.17 KB) Sorry - would be nice if I removed some debugging code - ;-) also previous patch also would have introduced a need for a change to the menu table that isn't required yet. This patch is a correct version andre ------------------------------------------------------------------------ January 20, 2005 - 19:16 : Dries The menu is recreated every time a book page is updated. I believe this is unwanted behavior because it requires the book block to be reconfigured upon every update. ------------------------------------------------------------------------ January 20, 2005 - 19:32 : andremolnar The menu is indeed re-created with every book page edit - because if the book page title changes the menu needs to reflect this change. The book block re-configuration is not required by the user. The code stores this information and re-sets the block settings. I will see if I can test for 'title change' before forcing the re-build of the menu - It would save a bit of processing power. andre ------------------------------------------------------------------------ January 20, 2005 - 20:21 : andremolnar Took another at this - and it turns out that I already have a check to see if title or weight change (rather - they already existed in the module and I used them). andre ------------------------------------------------------------------------ January 24, 2005 - 02:22 : andremolnar Attachment: http://drupal.org/files/issues/book_module_6.patch (7.42 KB) Feedback received indicated that the original block generation code in this module should be removed - since this patch hands block generation off to the menu and block system. This patch removes that code. BUT - It should be noted, that in order to have book blocks only show up on pages of node type book - an additional patch found at http://drupal.org/node/16074 is required. andre ------------------------------------------------------------------------ January 24, 2005 - 18:36 : andremolnar Attachment: http://drupal.org/files/issues/book_module_7.patch (7.43 KB) Yet another patch: Brings this patch in line with - http://drupal.org/node/16074 (i.e. the column name change in {block} table) andre ------------------------------------------------------------------------ January 25, 2005 - 18:56 : andremolnar Attachment: http://drupal.org/files/issues/book_module_8.patch (7.53 KB) And another minor patch to cover coding style and variable names. Just to bring everyone up to speed: 1) Each book and its children pages have a menu created for them (on any add, edit, delete to a book or book page). 2) Those book menus automatically have a block created for them via menu_block hook. 3) Block settings are preserved any time there is a change to a book that requires the menu and its associated block to be re-built. 4) book_block hook is removed because it is redundant. 5) With the addition of the configuration option in blocks to only show blocks on certain node types (see: http://drupal.org/node/16074) administrators have full control over when and where a book block shows up (including maintaining the status quo of only having book blocks show up on book pages). 6) This patch does require http://drupal.org/node/15198 andre ------------------------------------------------------------------------ January 25, 2005 - 21:49 : Boris Mann +1!! Book-based automatic navigation for corporate/brochureware sites! Fantastic! Chris Messina, get in here and add a +1 to this. ------------------------------------------------------------------------ January 25, 2005 - 22:26 : Dries Boris, have you tested this patch extensively, or are you just giving this +1 based on what you've read? If you want to see this committed, take the time to review/test it. ------------------------------------------------------------------------ January 26, 2005 - 05:45 : andremolnar Yes - please - testers are welcome. Nysus (aka Steve) has already agreed to give this a test drive when he had a spare moment. I hope for some feedback in the near future. But if you have a moment Borris I would appreciate it. OR - If someone would just like to demo this: http://s92258948.onlinehome.us/greenbeach/ UN: drupaldev PW: drupaldev Don't mind the mess - it is my test environment and there is a lot of junk data and settings floating around - but this patch is running there along with the additional block configuration settings. andre ------------------------------------------------------------------------ January 31, 2005 - 19:12 : Boris Mann You got me, Dries... I have since spent time testing the module on andre's site, and it does everything I can foresee needing at this point, with no functional errors. This functionality alone will make creating standalone sites that are composed of mainly static pages very, very simple. ------------------------------------------------------------------------ February 3, 2005 - 08:58 : Dries The demo-site appears to be down. Bummer. ------------------------------------------------------------------------ February 3, 2005 - 22:59 : andremolnar Attachment: http://drupal.org/files/issues/book_module_9.patch (7.58 KB) Sorry - demo site was down while database was being cleaned and latest CVS modules were being installed (general site maintenence for testing). The site is up now with a fresh database and install of Drupal CVS. UN drupaldev PW drupaldev (has access to manage blocks, books, and menus to see this patch in action) Attached is an updated patch to make use of db_rewrite_sql (instead of node_rewrite_sql). Also fixes a minor bug that appeared if you were creating the first book in the site. andre ------------------------------------------------------------------------ February 3, 2005 - 23:13 : Anonymous This patch seems to modify the blocks and menu tables directly from within book.module. (in the new book_build_menu_module_menu function) This sets a terrible precedent for other modules. IMO, these tables should be modified by functions defined within the block module or menu module (or menu.inc). Modifying the tables randomly throughout many other points in the code makes changes to these tables difficult and makes troubleshooting problems much trickier. Let's not sacrafice code organization for the sake of making the patch as small as possible. ------------------------------------------------------------------------ February 4, 2005 - 06:25 : andremolnar With regard to the blocks - the block module is doing all the block building (with the call to _block_rehash) - the only thing that this code does is preserve block settings (the select sql) before the menu is updated - and then restores those block settings (with the update sql). "Modifying the tables randomly throughout... " While I appreciate the point you are making, I would hesitate to call this random. After all the menu items being added to the menu table 'belong' to book module. There is a little bit of a discussion about the best way to go about doing this sort of thing (i.e. allowing modules to build their own menus) over at http://drupal.org/node/15198 - which includes the patch required to make this patch work. Right now there is no existing hook or method of doing this. hook_menu does not have anything in place as of yet. I have suggested the introduction of a new hook (name yet to be determined) that would be in charge of these menu_module_menu type inserts. But, I haven't heard any feedback on whether that is a good idea - or if anyone has a better idea. Anyone else have thoughts on the approach taken here or suggestions for a different/better approach? I'm willing to write the code, I would just like a little bit of input. andre ------------------------------------------------------------------------ February 4, 2005 - 06:46 : Dries I added a test page and all book blocks dissapeared? I also got an SQL error (check your watchdog messages) upon pressing the 'Submit' button. ------------------------------------------------------------------------ February 5, 2005 - 07:31 : Steven Doesn't this patch still suffer from the inability to show the menu block only on the relevant book(s)? I know we can now restrict blocks per node type, but that still doesn't help with multiple books. By the way, big code style violation: $menu_block_settings[$menu_block->path][weight] "weight" should be surrounded by quotes. Right now it is being treated as an undefined constant. This is not a good idea. Other than that there's a bunch of missing spaces... if the code looks cramped, it usually violates the coding style. + $menu_block_settings[$result->path] = array('status'=>$result->status, 'weight'=>$result->weight, 'region'=>$result->region, 'throttle'=>$result->throttle, 'visibility'=>$result->visibility, 'pages'=>$result->pages, 'types'=>$result->types); + db_query('DELETE FROM {menu} WHERE type=%d OR type=%d', MENU_MODULE_MENU | MENU_MODIFIED_BY_MODULE, MENU_MODULE_ITEM | MENU_MODIFIED_BY_MODULE); //restore menu_module_menu block settings There are several more examples. Please pay attention to this. It's incredibly annoying to have to fix it later, and it makes the code harder to read as you cannot make certain assumptions about how it is layed out. ------------------------------------------------------------------------ February 5, 2005 - 22:56 : andremolnar I am fixing up the code as we speak. I actually made a bigger faux pas by not escaping my INSERT sql string properly - (There is a quick fix, but I understand 'addslashes' is not good enough for drupal ;-). (Thank you to Dries for catching this right away on his test of the demo site). As for multiple books - you actually have more flexibility to enable as many book menus as you like - not only based on type but also by path. e.g. Could allow for: drupal.org/handbook (with some general book menu blocks enabled) drupal.org/handbook/developer (with developer book menu blocks enabled) drupal.org/handbook/developer/theme (with theme developer book menu blocks enabled) etc. (the sky is the limit). I will resubmit a patch with all of the coding style fixes requested - and I will be more careful with the coding style in the future. andre ------------------------------------------------------------------------ February 6, 2005 - 00:05 : andremolnar Attachment: http://drupal.org/files/issues/book_module_10.patch (7.7 KB) Updated Patch, Implemented code style improvements as per Steven. Fixed unescaped sql INSERT string (turns out that addslashes is more than enough in this situation, because the 'title' string has already been valided and properly inserted into the database before any of this code ever runs - i.e. this isn't coming directly from user input, but rather from the drupal database). Demo site is once again live and welcomes all testers (Thank you again to those that have already tested this out). andre ------------------------------------------------------------------------ March 13, 2005 - 22:11 : killes(a)www.drop.org Still applies. Andre: Please create patches from the Drupal root directory. ------------------------------------------------------------------------ March 15, 2005 - 10:42 : Paul Iliano This is exactly the functionality I have been waiting for. As I can see many uses for showing a book menu on all pages, I never really understood why book menus could only be shown on book pages. I'm still at DP 4.5, but as soon as 4.6 is out I will install and try it out. I'd love to see this kind of functionality in core! ------------------------------------------------------------------------ March 18, 2005 - 07:43 : Steven Your visibility 'fix' requires that the entire handbook has clean, hierarchical URL aliasing. This is often not the case. I understand that for sites where the book is used to organise the main structure, you might want the block visible everywhere. But it is not good for sites where this isn't the case, like Drupal.org itself. ------------------------------------------------------------------------ April 3, 2005 - 17:12 : Paul Iliano As Steven says, for some type of sites (like perhaps drupal.org) it could not be desirable to show book menus on all pages. But for other sites it could be very much wanted. It seems to me a good solution would be to let administrators simply choose which node types they want book menus to appear on, like we currently can opt to switch off author/date info per node type. ------------------------------------------------------------------------ April 3, 2005 - 22:49 : factoryjoe In general, +1 on the auto-updating aspect of this. It does seem to be a welcome improvement to the book system, though I question Boris’ assertion that this is really a good solution for “brochure-ware” sites. For one thing, when I design a site, no matter who I am, I highly doubt that I would think “ah ha, make a book to contain the pages of my site... and the navigation will be generated from it!” While the functionality is pretty much spot-on, the name is not. So what we end up with is an overloaded book module or worse, a misnamed module. I also wonder about moving the book-generated menus around. For example, the way I would like this patch to work is for there to be top-level “chapters” (like sections of a website) and then book pages within each section, representing the individual pages. I would like to be able to put the “chapters” horizontally in the header of my site (like on OurMedia.org [1]) and then have the pages show up in the sidebar when you navigate to each section. I guess I just wonder about the flexibility of this approach and whether or not it will serve the functional needs that Boris thinks it might. What if I want the page titles to be different from the menu link titles? It doesn't seem that this is something I can control with the current partial menu integration. Anyway, with a specific eyes towards improving book navigation, I do agree that it functionally looks pretty good. I did find one serious bug and one major usability issue. It has to do with integration with the menu system. Andre will hate me for this, but I clicked through the “reset menus” command in the menu system. Doing so wiped out all the book navigation menus. If these menu items were really “locked”, then why were the book menu items wiped out? How do I restore them? As for the usability issue, it is unclear to me where I would go reorganize my book-generated navigation menus. I looked in menus, where it should logically exist, but everything was locked. Does this mean I have to go to each individual node to sort my content? [1] http://www.ourmedia.org/ ------------------------------------------------------------------------ April 5, 2005 - 23:24 : menesis >From what i see on demo site, there is no way to configure the site to act as it does now in case of multiple books - show book navigation block only for current book. I could only configure a block to show up on any book page, but it is shown while viewing other books, too. IMHO the preferred way to modify a module is to introduce new functionality while keeping it's behavior without any extra configuration. In this case, when creating a new book, a menu would be created, the block enabled, and configured to show up only on pages of that book. Visibility by path will not work, because all book pages have url like node/1653 by default, need a block setting for that (true="Show on any book's pages", false="Show only on current book's pages", false by default). The tricky part is that menu module, which provides the block and it's configuration, does not know which book is being displayed. ------------------------------------------------------------------------ April 17, 2005 - 21:38 : bobo For those of us without linux, can someone please add the latest patch to the Drupal 4.5 book.module. I would like to use it asap for a website I'm creating for an animal welfare group. This is really cool, I hope you guys find a way to get it put into the latest version of Drupal. It should be a core peice of code. It seems strange to me that an option to click wether or not you want a book to display on the main page doesn't exist... Bobo

[drupal-devel] [bug] Put revisions in their own table
by killes 18 Apr '05

18 Apr '05

Issue status update for http://drupal.org/node/7582 Project: Drupal Version: cvs Component: node system Category: bug reports Priority: normal Assigned to: killes(a)www.drop.org Reported by: killes(a)www.drop.org Updated by: killes(a)www.drop.org Status: patch Attachment: http://drupal.org/files/issues/revisions_24_0.patch (60.39 KB) Updated. killes(a)www.drop.org Previous comments: ------------------------------------------------------------------------ May 5, 2004 - 17:25 : killes(a)www.drop.org Currently all node revisions are stored in a serialized field in node.table and retrieved for _each_ page view although they are rarely needed. However, we have agreed that serializing data is bad and that we should try to keep the memory foot print pf Drupal small. Therefore I propose to create a separate revisions table which would be in principle identical to the node table, only that it could have several old copies of the same node. Extra data added by other modules could be added in a serialized field unless we find a better solution. ------------------------------------------------------------------------ May 5, 2004 - 18:06 : jhriggs I too think the serialized approach is less than desirable, but here's an alternative. This would likely take some considerable rework in core and contrib, but the following is how we handle similar types of situations in our databases at work. It is more elegant that a separate table, and avoids the (almost exact) duplication of a table. Instead of separate tables, keep all revisions of nodes in the node table as follows: * add field: active (0/1 or Y/N) * add field: revision * every revision of a node is stored in the node table; however, only one revision can be active at any given time * nid can no longer be unique -- primary/unique key becomes (nid, active) * any time a node is loaded, updated (without revision), etc., the active version is used. Thoughts? ------------------------------------------------------------------------ May 5, 2004 - 18:57 : killes(a)www.drop.org I am not opposed to your scheme, but I want to stress the following: * Duplicating a table's structure is not bad (IMHO) as long as the content is different. * having two tables will allow us to have a rather small node table. This is (maybe) a performance gain. ------------------------------------------------------------------------ May 5, 2004 - 19:37 : jhriggs I don't necessarily think that duplicating a table's structure is _bad_. It just seems to be wasteful and a pain to maintain. (Every change to the node table is made twice...easy to do, but also easy to miss perhaps.) As for performance, as long as nid and the active indicator are indexed, there shouldn't be any performance loss. Also, archiving an old version when making a new revision will be much simpler: just change the active indicator rather than copying an entire node to another table (and ensuring everything gets copied...again a potential maintainance issue). To be honest, I would just like to see the serialized data go away, regarless of what approach is taken. ------------------------------------------------------------------------ July 30, 2004 - 20:49 : Nick Nassar Attachment: http://drupal.org/files/issues/Drupal-Improved_Revision_Schema_07-30-2004.p… (10.47 KB) I'm interested in using Drupal for a large scale wiki-type project. In order to do this, I need revisions to be in their own table. Attached is a patch to do just that. Most of the changes are pretty self explanatory. Spreading out node data across two tables meant that I had to add database functions to do locking/transactions. Without this, race conditions in which the database becomes corrupted are possible. ------------------------------------------------------------------------ July 30, 2004 - 20:54 : Nick Nassar Oh yeah... The patch is a diff against Drupal CVS ------------------------------------------------------------------------ July 31, 2004 - 01:00 : Anonymous Gerhard speaking. Nick, thanks a lot for your nice patch! It saves me a great deal of labour. I looked through it and immediately liked it. You not only put the old revisions into a new table but also the current one. Do you have an estimate how much more expensive the additional join is? Besides a few minor coding style issues I found a major one: Just a few hours before you uploaded your patch JonBob's node access patch hit core. That means your patch won't apply anymore as all the queries you change have been changed. Can I bug you to update your patch? ------------------------------------------------------------------------ July 31, 2004 - 02:11 : Anonymous Also I think that your upgrade path loses existing revisions. ------------------------------------------------------------------------ July 31, 2004 - 03:39 : drumm I think this is the proper way to do things. No columns are duplicated, there is no serialized data, and only the fields that are logically revised are stored. Nothing jumped out at me as a way to have my node modules be able to keep a table of revisions of additional fields. I'm guessing this could be done within the confines of _insert and _update. Assuming the upgrade path works and modules can extend it I give it a +1. ------------------------------------------------------------------------ July 31, 2004 - 15:40 : Nick Nassar It figures that just as I finish a big patch, another patch comes along and breaks it. Oh well, it should be a pretty easy to fix. I'll work on it. Fixing the upgrade path to keep revisions should be fairly painless. I found another issue that needs to be fixed before this patch gets merged. There format of a node needs to be stored for each revision. Otherwise, for modules that store a format for the nodes, such as page and book, if you write one revision in PHP and the next in HTML, the PHP revision will be displayed as HTML. This is part of a larger issue of how node modules should store revisions of additional fields. I think each module that wants to do this should create another table with (nid, revid) as the primary key. Just as when they want to add fields to a node they create another table with nid as the primary key. As far as performance goes, for sites that make heavy use of revisions, an extra join on primary keys is going to be a lot faster than grabbing all of the revisions from that database everytime. We would need to run benchmarks to determine is the overall difference in speed is for an average site is a gain or a loss. I'm guessing it's very minor either way. ------------------------------------------------------------------------ August 23, 2004 - 14:55 : Nick Nassar Attachment: http://drupal.org/files/issues/Drupal-Improved_Revision_Schema_08-23-2004.p… (10.92 KB) Here's an updated patch against CVS that puts revisions in their own table, provides an upgrade path, and fixes the format related bugs in the last patch. Hopefully, this can make it into CVS as soon as the freeze is over. ------------------------------------------------------------------------ August 23, 2004 - 15:10 : moshe weitzman Interesting patch ... drumm's question is still outstanding. how do modules store revisions of their fields? Are they expected to manage this on their own? Thats not how it works today. As an aside, i am seeing profile_ fields in my node.revisions column. One could argue that those need not be saved. They pertain to the node author, not to the node itself. ------------------------------------------------------------------------ August 23, 2004 - 17:14 : Nick Nassar Having modules be responsible for storing revisions of their own fields is a side-effect of storing revision data in tables. There's really no way around it. However, revisions generally don't make sense for node types that don't have PHP/HTML content, such as polls. I think it's going to be a pretty rare scenario for a new node type to want another field to change per-revision, so it's a pretty good trade-off. Storing fields that shouldn't be part of revisions, such as the profile_ fields, is a side-effect of storing revisions as serialized objects. Applying this patch will free up that wasted space. :) ------------------------------------------------------------------------ August 23, 2004 - 18:20 : Anonymous There should be a hook that let's the module choose whether it supports history. This way a module author can prevent the user from doing something that may break his module or just cause undefined behavior. If the module doesn't support history then don't let the user/admin choose to add history to nodes of that type. Craig ------------------------------------------------------------------------ August 23, 2004 - 20:23 : Nick Nassar I agree, there should be an API change to make specifying support for revisions easier. In the interests of keeping patches small and keeping to one change per patch, I think the API change should be a separate issue. A sort of ad-hoc API to decide whether or not a module supports revisions by default already exists. Instead of having a hook, modules set the default value of the "Create new revision" field in the edit form. The admin can change this option in admin/node/configure/defaults. This patch doesn't change that. Revisions are broken for node types that have their own database structure, like polls, even when storing them as serialized objects. This patch doesn't change that, either. ------------------------------------------------------------------------ October 26, 2004 - 03:35 : moshe weitzman I'm guessing that someone is going to have to demonstrate that this patch performs as well as current drupal before it gets comitted. i think this patch is a few benchmarks from being comitted. ------------------------------------------------------------------------ October 27, 2004 - 02:04 : Nick Nassar Attachment: http://drupal.org/files/issues/Drupal-Improved_Revision_Schema_10-26-2004.p… (11 KB) I ran some really unscientific benchmarks, and it looks like this patch has a negligible affect on performance.

The command I used was: ab -n50 -C 'PHPSESSID=b01a9f92880ef215b0ed6f1314a5eba2' http://192.168.0.100/ An updated patch that should apply to CVS is attached. ------------------------------------------------------------------------ November 15, 2004 - 06:05 : elias1884 please overthink the revision system default workflow as well. don't look at the revision system as an isolated system but as a part of the whole workflow system! if you combine revisions with the moderation queue the most logic default workflow would be like that: auth user creates node (revision #0) admin approves the node (status = 1, moderation = 0) => node publicly available auth user finds typo and changes node (revision #1, status = 0, moderation = 1) ------- what happens at that point at the moment is, that the node is not accessible anymore at all until the new revision is approved by admin. of course the new revision should not go online until reviewed and approved, this is absolutely correct, but there is no reason to not take the old revision offline, since it was already approved and should therefore be online until the new revision is approved. it is not practical if a node disappears only because the author corrected a typo. ------- admin approves the node (status = 1, moderation = 0) eventhough I first thought a plain boolean active field would not be capable of providing that functionality if finally came to the conclusion, that it can. The only thing to do is to not set that bit, when a new revision is created, but when it is approved (in case moderation is activated under default workflow). Every revision should have its own moderation, status and active field and on approval they are set like this (status=1, moderation=0, active=Y). When you wanna rollback to an old revision, you can chose between all revisions that already have the moderation bit set back to 0 again and the published to 1. There should be an extra permission for rollback! another concern that I have about the default workflow is, that users can't see the content, they have just created, when moderation is enabled. Eventhough, there is a big fat "submission accepted" presented after submissions, unexperienced users tend to question the information those stupid tincans give them, if they can't find their content afterwards. Many users are really lazy bastards and they don't even read the status messages. The best feedback about whether his story was submitted successfully or not of course is, if he can find the story somewhere on the site, maybe with a status message on top of it, mentioning, that the content is currently not publicly available since it has not been approved yet. there should be a my content section under my account, like somebody is trying to do with the workspace module I guess. so my suggestion is to make (status=0, moderation=1) still available for the creator under a my content section somewhere! ------------------------------------------------------------------------ November 24, 2004 - 05:21 : Nick Nassar I agree. The current workflow for moderation queues and revisions needs to change, but this patch isn't the place for it. The patch is already too big, and it only does the backend stuff. Instead of adding more to this patch and making it take even longer to get into core, would you mind creating a new issue for your UI suggestions, so the those changes can be added as a separate patch? Thanks, Nick ------------------------------------------------------------------------ December 11, 2004 - 13:26 : Dries This patch is _much_ needed so I'd love to see someone revive it. In order for this patch to be accepted, the following needs to be done: Update this patch to CVS HEAD. Rename revid to vid. Rename node_rev to node_revisions. Rename node_rev.changed to node_revisions.timestamp. Rename $rnode to $revision. Fix the coding style to match Drupal's: proper spacing, single quotes where possible, proper variable names. Benchmark this patch with a large database with enough revisions. I'd be happy to benchmark this on my local copy of the drupal.org database. The book.log field should probably move to the node_revisions table. This can be done in a separate patch. Investigate whether transactions are well-supported. ------------------------------------------------------------------------ December 13, 2004 - 01:25 : killes(a)www.drop.org Attachment: http://drupal.org/files/issues/Drupal-Improved_Revision_Schema_10-26-2004-r… (11.02 KB) I've worked a bit on the patch (coding style issues as mentioned by Dries). One thing I noticed is that the patch uses REPLACE. IIRC this needs to be chagned to "UPDATE, if fail INSERT" for pgsql compatibility. Nick, are you still interested in working on that patch? I'd like to know how it works on your site and work on getting it into core. ------------------------------------------------------------------------ December 13, 2004 - 13:33 : Dries Gerhard: your patch does not apply. ------------------------------------------------------------------------ December 13, 2004 - 18:10 : killes(a)www.drop.org Yes, I know, that was the same version as I mailed to you earlier. ------------------------------------------------------------------------ December 13, 2004 - 22:02 : killes(a)www.drop.org Attachment: http://drupal.org/files/issues/revisions.patch (52.96 KB) Ok, upüdated the patch to cvs. ------------------------------------------------------------------------ December 14, 2004 - 09:58 : Dries Some more comments: db_begin_transaction() and db_end_transaction() do not belong in database.inc, but in database.mysql.inc and database.pgsql.inc respectively. The node module calls node_revisionsision_list() which is not defined. (Fxed that on my local copy.) Do db_begin_transaction() and db_end_transaction() deprecate Jeremy's table locking patch? The upgrade path assigns the wrong user ID to each revision. The upgrade path assigns the wrong date to each revision (that or a node's revision page shows the wrong usernames/dates). The coding style needs a bit of work, but we can worry about that later. ------------------------------------------------------------------------ December 14, 2004 - 18:34 : Nick Nassar If you need any help getting those things fixed, just let me know. ------------------------------------------------------------------------ December 14, 2004 - 18:50 : Nick Nassar How this relates to Jeremy's node locking patch: There was lots of discussion, and node locking was decided against because from an end user point of view you never want a node to be locked. He's now advocating for a much simpler patch that warns users if their changes will overwrite someone elses. That patch still has a race condition, which might be fixed using db_begin_transaction(). http://drupal.org/node/6025 ------------------------------------------------------------------------ December 14, 2004 - 23:26 : killes(a)www.drop.org Attachment: http://drupal.org/files/issues/revisions_0.patch (55.96 KB) Here is an updated patch that tries to address Dries concerns. ------------------------------------------------------------------------ December 15, 2004 - 09:32 : Dries Attachment: http://drupal.org/files/issues/revisions-bug.png (76.06 KB) It didn't fix the aforementioned bugs.

Dries and myself worked hart at it, so please have a look. what is still missing - database upgrades for the core modules with an own table - contrib modules need an upgrade too. - do we need nid and vid in both the node and the node_revisions table? - the amount of sql queries means a good stress testing for large databases. ------------------------------------------------------------------------ January 19, 2005 - 22:43 : killes(a)www.drop.org Attachment: http://drupal.org/files/issues/revisions_2.patch (49.49 KB) Here is an updated patch. We discussed to keep the current title in node module and also in the revisiosn table. This is content duplication but will save many joins as many queries only need the title of a node.

Maybe somebody else has an older db to try. @robertDouglass: The first effect you describe is due to drupaldevs running on PHP 5. I am unsure why the second thing does not work. In node_save() the node object has a nid although there is none in the form. Very strange. I've enabled display of db queries on the testsite. ------------------------------------------------------------------------ February 4, 2005 - 20:17 : dmjossel No results here on the query: select nid,type from node where type like '%/%'; On a database that was put in place prior to Drupal 4 and is now running on 4.5.2. ------------------------------------------------------------------------ February 4, 2005 - 21:44 : killes(a)www.drop.org @dmjossel: thanks. @all. The strange problem I reported was apparently php 5 related. After applying Steven's php 5 patch it went away. One error is remaining: If I create a new forum topic it will be shown as part of the book on preview. Hmm, that was due to a db that got corrupted during testing so that is fixed too. Please poke around at the test site and look if you find more errors. ------------------------------------------------------------------------ February 5, 2005 - 08:16 : Steven By the way, I just remembered that Drupal.org has some blogs lingering on in the database even though blog.module is not enabled. Perhaps this is causing troubles? ------------------------------------------------------------------------ February 5, 2005 - 12:22 : Anonymous I can't see why it would.

Changes from previous versions: - supports versioning for uploaded files. A problem is that if you delete a file, it will be gone for all revisions. - the log field is now in the node_revsions table, but each module has to decide whether to show it or not. I've implemented it for the page and the book type odes. Also, the field can be edited when adding non-book nodes to the book. The log is displayed on the revisions page and if a node is moderated. - the revisions are moved to an old_revisions table to a) get the node table smaller and b) still leave the mavailable for contrib modules that want to retreive old version data. The patch has been applied to killes.drupaldevs.org/revision where it can be tested by anybody (especially people who have "site admin" rights on drupal.org) The database is from drupal.org and you should b able to log in with your pass or simply mail yourself a new one.

The changes to node_save appear to be needed because recent patches (both 21 and 22) remove the field 'title' from table 'node'.

[drupal-devel] [feature] Enable multiple block regions (not just "left" and "right" sidebars)
by nedjo 18 Apr '05

18 Apr '05

Issue status update for http://drupal.org/node/16216 Project: Drupal Version: cvs Component: block.module Category: feature requests Priority: normal Assigned to: Anonymous Reported by: paragkenia Updated by: nedjo Status: patch Attachment: http://drupal.org/files/issues/block-dynamic-regions2.patch (13.39 KB) Here's a revised patch implementing some of the ideas so far. I've used the theme engine - rather than individual themes - to generate the list of available regions. I know this isn't ideal, but e.g. for xtemplate it's at present the only option--no logic is possible in the individual theme. region is changed to a varchar field from the current tinyint. I've roughed in several regions--really just for demo purposes. More thought and work would be needed to refine them (e.g., styling, etc.). But this maybe moves the conversation forward. nedjo Previous comments: ------------------------------------------------------------------------ January 26, 2005 - 06:27 : paragkenia I read the comparision discussion between *Drupal* and *Mambo*. In several messages it was outlined that Drupal can place blocks only in right and left and not flexible to put them on anywhere where one want. It will be great if this can be changed in upcoming versions. I am no pro at PHP, so don't know how much time this task will take, but I think it is very important. parag ------------------------------------------------------------------------ April 14, 2005 - 21:44 : nedjo This issue was apparently partially addressed in issue http://drupal.org/node/19694 [1]. [1] http://drupal.org/node/19694 ------------------------------------------------------------------------ April 16, 2005 - 20:24 : nedjo Attachment: http://drupal.org/files/issues/block-dynamic-regions.patch (8.17 KB) This much-requested functionality - to have the ability to place blocks in more than the two predefined regions - was partially addressed in issue http://drupal.org/node/19694. [2]. But "blocks" are still limited to the "left" and "right" sidebars (hard-coded in block.module). This patch is a first step designed to enable multiple (eventually, admin-definable) regions for blocks. I've moved the existing "left" and "right" block regions to a 'region' table (with ids of 0 and 1, as currently used in themes). Then all references to the regions are drawn dynamically from the table. This way, if further records are added, they will appear in the list of available regions for block placement. Doing this actually reduces some duplicated code, since it's no longer necessary to repeat code blocks for each of "left" and "right". As it stands, the patch doesn't add any new functionality--but I don't think it breaks anything either. New functionality would need (a) new regions defined, and (b) changes to themes. A simple first step might be, e.g., to add a "footer" region and then add a call in the footer generation to append any blocks assigned to the footer region there. I'm setting this to patch, but I'm aware that it needs some discussion and refining before it'll be ready to apply. [2] http://drupal.org/node/19694. ------------------------------------------------------------------------ April 16, 2005 - 21:05 : nedjo Attachment: http://drupal.org/files/issues/block_regions.png (5.65 KB) Here's a screenshot showing the block admin page, with drop-downs for region placement (the options are dynamically generated based on defined regions). ------------------------------------------------------------------------ April 16, 2005 - 22:57 : adrian The biggest problem with this is that you can have multiple themes, and each of these themes can have different regions available. Also, the method of defining which regions are available needs to be standardised. Some of the work that me and Vlado are working on for the install system would go towards solving that problem (ie: meta information for modules, themes and styles). This has been discussed to death, but the general consensus has been that we _want_ to do this, but we need to solve a few other problems properly first, the most pertinent being the interface issue. Chris (factoryjoe) recently did a whole mess of workflows for something related to this. ------------------------------------------------------------------------ April 17, 2005 - 00:09 : syscrusher The first paragraph of adrian [3]'s post is a point that occurred to me also, as I read this thread. One suggestion would be to separate the definition and configuration of blocks, on one hand, from the placement of those blocks, on the other hand. In other words, Drupal core provides a mechanism defining what blocks exist, which of these are on by default or off by default and user-selectable vs. which are forced on for all users, and the configuration (if applicable) of specialized blocks defined by particular modules. Each theme provides a standard hook function that returns an array of region names and help/description text, e.g., array('left'=>t('This vertical region is left of the main content area'), 'right'=>t('This vertical region is right of the main content area'), 'footer'=>t('The footer is below the left, right, and main content areas of the page')). The theme part of Drupal core (i.e., theme.module itself, not the individual themes) provides a standard UI that is displayed within config of *each theme* (but is one physical code base within theme.module) that allows the administrator to map blocks defined by Drupal core into regions defined by the theme, and storing that mapping as an theme-to-block_ID-to-region_ID (with weight) table in the database. From there, the actual page rendering is similar to what's being done now, but there is more of it. I guess what I'm trying to say is that the key to solving this problem is breaking it along its degrees of orthogonality, and there are three -- two in Drupal core and one in the individual theme. Scott [3] http://drupal.org//user/1517 ------------------------------------------------------------------------ April 17, 2005 - 03:14 : Dries Scott, is right. The theme should export its available regions. Then the administrator's task is to assign blocks to regions (not to setup regions). A theme could have configurable regions, but that internal to the theme. To me, the real challenge is the UI and the interaction design. Configuring blocks could easily become a real pain (while most themes continue to use 'left' and 'right'.) Of course, we can implement all the functionality, default everything to 'left' and 'right', and worry about the UI later. This should be fairly straightforward to implement and nedjo's patch looks like a first step in the right direction. ------------------------------------------------------------------------ April 17, 2005 - 17:09 : nedjo I agree with the suggested approach of themes registering their regions. I'd see this happening when a particular theme is activiated (or upgraded). Regions would be an array of names (e.g., 'left', 'right', 'footer'). New records would be created in the region table only for region names not previously registered. Some areas I'm not clear on, or that need further work: Table naming Should a new table be 'region' or 'regions' (I've used 'region')? I don't see a convention among existing table names, some of which are singular and others plural. Default values I've kept the existing '0' and '1' ids for regions (left and right, respectively), for backward compatibility. But this means we can't use autoincrement for the region id (rid), since autoincrements seem to begin with 1. Likely we should change to autogenerated ids. Initial records Using the INSERT INTO statements as I've done for the initial region entries is probably counterproductive, since sooner or later they'll have to be dynamically generated. I was hoping this could be a preliminary patch, with the main work coming later, but likely we need to solve region registration by themes before this patch is applied. I don't have a good idea of how region registration by themes would be implemented (a hook on theme activation?), and invite suggestions or implementations. Theme system changes Besides region registration, the other change I'm seeing that would be needed in the theme system is loading blocks by region name, rather than region id. This is because the ids currently used ('0' and '1') in theory might be diffferent on a particular install. ------------------------------------------------------------------------ April 17, 2005 - 17:18 : syscrusher Instead of having themes "register" their regions, why not just add a theme API hook called them_regions() that returns an associative array of $region_name=>t($region_helptext)? This would be in keeping with other similar API functions, such as those that return what permissions apply to a module or what node types are defined by a module. Most themes are going to define only a small number of regions (two being the typical case now, but I could see five or six in a complex theme), so returning a constant array will be faster than querying SQL to obtain an array of rows. There could be (optionally, at the discretion of whoever builds this thing) another API hook like theme_region_properties($region_name) that returns an associative array with detailed info for a given region, such as extended help text with recommended usage instructions for the region. Scott ------------------------------------------------------------------------ April 17, 2005 - 17:19 : syscrusher s/them_regions/theme_regions/g ------------------------------------------------------------------------ April 17, 2005 - 18:47 : adrian Because. The most common 'theme' is a phptemplate theme. And there needs to be a generic method for specifying the regions available, in a non hook_function format.. Themes get their names from the directory in which they are contained.. when copying the theme to another directory, there must be _no_ modifications necessary to allow normal usage. This is one of the tenets of the new template system I designed. You would need a standard way to define meta-information for themes, that does not need to be modified when copied to a new directory. We are working on this in the install system work, as you need a way external of Drupal to define the module dependencies and some other things. My approach would be to add a theme.dsc text file to the directory, which would allow you to specify meta-information. For instance : ---- regions: left, right, footer, center, mountie author: Johnny McAngstyPants ---- ------------------------------------------------------------------------ April 17, 2005 - 22:00 : syscrusher Adrian wrote: " Themes get their names from the directory in which they are contained.. when copying the theme to another directory, there must be _no_ modifications necessary to allow normal usage. This is one of the tenets of the new template system I designed. " A very good point. But region names don't have to be unique across different themes, so my hook function wouldn't have to be modified. The suggestion I made for the mapping metadata was three factors: theme ID or name, region ID or name, and block ID (plus one non-key weight value to order the blocks within a region, but this is not relevant here). I'm not familiar enough with PHP template to be able to respond to your comments on that one, so if you say it's not feasible to work with my schema, then I'll take your word for it. :-) Scott ------------------------------------------------------------------------ April 17, 2005 - 22:03 : syscrusher Oh, wait.....I see now what you mean! It's not the output of the function that is the problem, but the *name* of the function. Never mind. I concede your point. Scott ------------------------------------------------------------------------ April 18, 2005 - 03:44 : Jaza I'm probably jumping ahead a bit here... but something that this patch will have to eventually account for, is how to allow regions to be defined as inline. Allowing a theme to define a region's position as being anywhere on the edge of the page (i.e. top, left, right, bottom, corners, etc) is relatively easy. But what about having a region that's in the middle of a node's body, or somewhere else that's not the edge of the page? What I'm thinking of, is eventually allowing the custom region system to integrate with the CCK. Like I said, I admit that I'm jumping ahead into the future - the CCK still has a long way to go before it's ready. But ultimately, it would be cool if a theme could define a region as being after, say, the "rating" field in nodes of type "movie review". This would make the region (and the blocks in it) truly inline and in context with the actual content of the node. This would be a huge step forward compared to the current block system, which doesn't allow you to mix the presentation of blocks and nodes at all. In Drupal ATM, blocks and "the rest of the page" are totally separate, and really you have no choice but to display them as such. The result of this is that information in blocks that really should be displayed as part of a node, gets literally "pushed to the side", and always seems secondary to the actual content. Often the block has content that is just as important as the content of the node itself. Another option (of less merit, IMO - because of the extra maintenance work, and lack of enforced consistency) would be to have a region filter. You could then choose where to place an inline region on a per-node basis, by entering text such as [region:2] (example based on image_filter syntax) into the node body. Anyway, just thought I'd throw that idea into the open. I don't expect it will be implemented any time soon, but it's something to think about.

Re: [drupal-devel] Permissions aren't transparent

There is some PHP BB system that has something like this. I think it is PHPBB. At the bottom of the page, they state something such as: You *can* reply to topics in this forum You *cannot* post attachments in the forum ... Is this the direction that this is going to go in? While it is informative, from a usability perspective (in my opinion) that would be good, providing that you explain why you *cannot* perform an action. This raises the argument that the permission system (and where to display these permission for the end user) might become bulky and/or cluttered... Regards, Kobus > I think it is a good idea to have permission explained this way (it is > much more case sensitive then what we have now with some help texts > describing permissions). But if you would like to display this on the user > page, it needs to have different wording, like: > > You are able to create content of type foo.

Hi! I don't know if there are negative implications because of the proposed change, Iif there is, disregard my opinion, but I believe that this is 'n must-have +1. Regards, Kobus >>> killesreiter(a)physik.uni-freiburg.de 4/18/2005 2:09:59 PM >>> Hi there! One problem with Drupal is the way it handles user permissions. The permissions are attached to the user object but nobody really knows what they do. To find out what a particular permission allows you to do, you often need to have a look at the code. More important: The user does not know which permissions he has. I propose to change the structure of the _perm hook: foo_perm() { return array('create foo', 'admin foo'); } is the current structure. foo_perm() { return array('create foo' => t('Lets you create nodes of type foo.'), 'admin foo' => t('Lets you administer nodes of type foo.') ); } is the proposed structure. The idea is to not only display the additional blurb on the admin permission page, but also on a sub tab of the user profile pages (or directly on /user/n). Opinions? Cheers, Gerhard

[drupal-devel] [bug] file_check_location is not working on Windows 2000

Thanks. eric ec Previous comments: ------------------------------------------------------------------------ September 16, 2004 - 14:46 : ccourtne Currently file_check_location is always returning false when passed a file as the $source path. If a directory is passed in $soruce file_check_location works. I've tracked this down to realpath returning an empty string when passed a relative path which points to a file. This probably goes unnoticed if you are using the file.api's to construct relative paths to the druapl file directory since check_location failing just causes the durpal file directory to get added which is what you wanted in the first place. Replacing this line $source = realpath(dirname($source)); with this $source = realpath(dirname($source)); fixes it on my windows box using PHP 4.3.8. I don't have things set up to do patches on my windows boxes here at work yet.

[drupal-devel] [feature] Enable multiple block regions (not just "left" and "right" sidebars)

In several messages it was outlined that Drupal can place blocks only in right and left and not flexible to put them on anywhere where one want. It will be great if this can be changed in upcoming versions. I am no pro at PHP, so don't know how much time this task will take, but I think it is very important. parag ------------------------------------------------------------------------ April 15, 2005 - 03:44 : nedjo This issue was apparently partially addressed in issue http://drupal.org/node/19694 [1]. [1] http://drupal.org/node/19694 ------------------------------------------------------------------------ April 17, 2005 - 02:24 : nedjo Attachment: http://drupal.org/files/issues/block-dynamic-regions.patch (8.17 KB) This much-requested functionality - to have the ability to place blocks in more than the two predefined regions - was partially addressed in issue http://drupal.org/node/19694. [2]. But "blocks" are still limited to the "left" and "right" sidebars (hard-coded in block.module). This patch is a first step designed to enable multiple (eventually, admin-definable) regions for blocks. I've moved the existing "left" and "right" block regions to a 'region' table (with ids of 0 and 1, as currently used in themes). Then all references to the regions are drawn dynamically from the table. This way, if further records are added, they will appear in the list of available regions for block placement. Doing this actually reduces some duplicated code, since it's no longer necessary to repeat code blocks for each of "left" and "right". As it stands, the patch doesn't add any new functionality--but I don't think it breaks anything either. New functionality would need (a) new regions defined, and (b) changes to themes. A simple first step might be, e.g., to add a "footer" region and then add a call in the footer generation to append any blocks assigned to the footer region there. I'm setting this to patch, but I'm aware that it needs some discussion and refining before it'll be ready to apply.

Also, the method of defining which regions are available needs to be standardised. Some of the work that me and Vlado are working on for the install system would go towards solving that problem (ie: meta information for modules, themes and styles). This has been discussed to death, but the general consensus has been that we _want_ to do this, but we need to solve a few other problems properly first, the most pertinent being the interface issue. Chris (factoryjoe) recently did a whole mess of workflows for something related to this. ------------------------------------------------------------------------ April 17, 2005 - 06:09 : syscrusher The first paragraph of adrian [3]'s post is a point that occurred to me also, as I read this thread. One suggestion would be to separate the definition and configuration of blocks, on one hand, from the placement of those blocks, on the other hand. In other words, Drupal core provides a mechanism defining what blocks exist, which of these are on by default or off by default and user-selectable vs. which are forced on for all users, and the configuration (if applicable) of specialized blocks defined by particular modules. Each theme provides a standard hook function that returns an array of region names and help/description text, e.g., array('left'=>t('This vertical region is left of the main content area'), 'right'=>t('This vertical region is right of the main content area'), 'footer'=>t('The footer is below the left, right, and main content areas of the page')). The theme part of Drupal core (i.e., theme.module itself, not the individual themes) provides a standard UI that is displayed within config of *each theme* (but is one physical code base within theme.module) that allows the administrator to map blocks defined by Drupal core into regions defined by the theme, and storing that mapping as an theme-to-block_ID-to-region_ID (with weight) table in the database. From there, the actual page rendering is similar to what's being done now, but there is more of it. I guess what I'm trying to say is that the key to solving this problem is breaking it along its degrees of orthogonality, and there are three -- two in Drupal core and one in the individual theme. Scott [3] http://drupal.org//user/1517 ------------------------------------------------------------------------ April 17, 2005 - 09:14 : Dries Scott, is right. The theme should export its available regions. Then the administrator's task is to assign blocks to regions (not to setup regions). A theme could have configurable regions, but that internal to the theme. To me, the real challenge is the UI and the interaction design. Configuring blocks could easily become a real pain (while most themes continue to use 'left' and 'right'.) Of course, we can implement all the functionality, default everything to 'left' and 'right', and worry about the UI later. This should be fairly straightforward to implement and nedjo's patch looks like a first step in the right direction. ------------------------------------------------------------------------ April 17, 2005 - 23:09 : nedjo I agree with the suggested approach of themes registering their regions. I'd see this happening when a particular theme is activiated (or upgraded). Regions would be an array of names (e.g., 'left', 'right', 'footer'). New records would be created in the region table only for region names not previously registered. Some areas I'm not clear on, or that need further work: Table naming Should a new table be 'region' or 'regions' (I've used 'region')? I don't see a convention among existing table names, some of which are singular and others plural. Default values I've kept the existing '0' and '1' ids for regions (left and right, respectively), for backward compatibility. But this means we can't use autoincrement for the region id (rid), since autoincrements seem to begin with 1. Likely we should change to autogenerated ids. Initial records Using the INSERT INTO statements as I've done for the initial region entries is probably counterproductive, since sooner or later they'll have to be dynamically generated. I was hoping this could be a preliminary patch, with the main work coming later, but likely we need to solve region registration by themes before this patch is applied. I don't have a good idea of how region registration by themes would be implemented (a hook on theme activation?), and invite suggestions or implementations. Theme system changes Besides region registration, the other change I'm seeing that would be needed in the theme system is loading blocks by region name, rather than region id. This is because the ids currently used ('0' and '1') in theory might be diffferent on a particular install. ------------------------------------------------------------------------ April 17, 2005 - 23:18 : syscrusher Instead of having themes "register" their regions, why not just add a theme API hook called them_regions() that returns an associative array of $region_name=>t($region_helptext)? This would be in keeping with other similar API functions, such as those that return what permissions apply to a module or what node types are defined by a module. Most themes are going to define only a small number of regions (two being the typical case now, but I could see five or six in a complex theme), so returning a constant array will be faster than querying SQL to obtain an array of rows. There could be (optionally, at the discretion of whoever builds this thing) another API hook like theme_region_properties($region_name) that returns an associative array with detailed info for a given region, such as extended help text with recommended usage instructions for the region.

The most common 'theme' is a phptemplate theme. And there needs to be a generic method for specifying the regions available, in a non hook_function format.. Themes get their names from the directory in which they are contained.. when copying the theme to another directory, there must be _no_ modifications necessary to allow normal usage. This is one of the tenets of the new template system I designed. You would need a standard way to define meta-information for themes, that does not need to be modified when copied to a new directory. We are working on this in the install system work, as you need a way external of Drupal to define the module dependencies and some other things.

Scott ------------------------------------------------------------------------ April 18, 2005 - 09:44 : Jaza I'm probably jumping ahead a bit here... but something that this patch will have to eventually account for, is how to allow regions to be defined as inline. Allowing a theme to define a region's position as being anywhere on the edge of the page (i.e. top, left, right, bottom, corners, etc) is relatively easy. But what about having a region that's in the middle of a node's body, or somewhere else that's not the edge of the page? What I'm thinking of, is eventually allowing the custom region system to integrate with the CCK. Like I said, I admit that I'm jumping ahead into the future - the CCK still has a long way to go before it's ready. But ultimately, it would be cool if a theme could define a region as being after, say, the "rating" field in nodes of type "movie review". This would make the region (and the blocks in it) truly inline and in context with the actual content of the node. This would be a huge step forward compared to the current block system, which doesn't allow you to mix the presentation of blocks and nodes at all. In Drupal ATM, blocks and "the rest of the page" are totally separate, and really you have no choice but to display them as such. The result of this is that information in blocks that really should be displayed as part of a node, gets literally "pushed to the side", and always seems secondary to the actual content. Often the block has content that is just as important as the content of the node itself. Another option (of less merit, IMO - because of the extra maintenance work, and lack of enforced consistency) would be to have a region filter. You could then choose where to place an inline region on a per-node basis, by entering text such as [region:2] (example based on image_filter syntax) into the node body. Anyway, just thought I'd throw that idea into the open. I don't expect it will be implemented any time soon, but it's something to think about. Jeremy

Jeremy Jaza Previous comments: ------------------------------------------------------------------------ January 26, 2005 - 20:27 : paragkenia I read the comparision discussion between *Drupal* and *Mambo*. In several messages it was outlined that Drupal can place blocks only in right and left and not flexible to put them on anywhere where one want. It will be great if this can be changed in upcoming versions. I am no pro at PHP, so don't know how much time this task will take, but I think it is very important. parag ------------------------------------------------------------------------ April 15, 2005 - 11:44 : nedjo This issue was apparently partially addressed in issue http://drupal.org/node/19694 [1]. [1] http://drupal.org/node/19694 ------------------------------------------------------------------------ April 17, 2005 - 10:24 : nedjo Attachment: http://drupal.org/files/issues/block-dynamic-regions.patch (8.17 KB) This much-requested functionality - to have the ability to place blocks in more than the two predefined regions - was partially addressed in issue http://drupal.org/node/19694. [2]. But "blocks" are still limited to the "left" and "right" sidebars (hard-coded in block.module). This patch is a first step designed to enable multiple (eventually, admin-definable) regions for blocks. I've moved the existing "left" and "right" block regions to a 'region' table (with ids of 0 and 1, as currently used in themes). Then all references to the regions are drawn dynamically from the table. This way, if further records are added, they will appear in the list of available regions for block placement. Doing this actually reduces some duplicated code, since it's no longer necessary to repeat code blocks for each of "left" and "right". As it stands, the patch doesn't add any new functionality--but I don't think it breaks anything either. New functionality would need (a) new regions defined, and (b) changes to themes. A simple first step might be, e.g., to add a "footer" region and then add a call in the footer generation to append any blocks assigned to the footer region there. I'm setting this to patch, but I'm aware that it needs some discussion and refining before it'll be ready to apply.

Also, the method of defining which regions are available needs to be standardised. Some of the work that me and Vlado are working on for the install system would go towards solving that problem (ie: meta information for modules, themes and styles). This has been discussed to death, but the general consensus has been that we _want_ to do this, but we need to solve a few other problems properly first, the most pertinent being the interface issue. Chris (factoryjoe) recently did a whole mess of workflows for something related to this. ------------------------------------------------------------------------ April 17, 2005 - 14:09 : syscrusher The first paragraph of adrian [3]'s post is a point that occurred to me also, as I read this thread. One suggestion would be to separate the definition and configuration of blocks, on one hand, from the placement of those blocks, on the other hand. In other words, Drupal core provides a mechanism defining what blocks exist, which of these are on by default or off by default and user-selectable vs. which are forced on for all users, and the configuration (if applicable) of specialized blocks defined by particular modules. Each theme provides a standard hook function that returns an array of region names and help/description text, e.g., array('left'=>t('This vertical region is left of the main content area'), 'right'=>t('This vertical region is right of the main content area'), 'footer'=>t('The footer is below the left, right, and main content areas of the page')). The theme part of Drupal core (i.e., theme.module itself, not the individual themes) provides a standard UI that is displayed within config of *each theme* (but is one physical code base within theme.module) that allows the administrator to map blocks defined by Drupal core into regions defined by the theme, and storing that mapping as an theme-to-block_ID-to-region_ID (with weight) table in the database. From there, the actual page rendering is similar to what's being done now, but there is more of it. I guess what I'm trying to say is that the key to solving this problem is breaking it along its degrees of orthogonality, and there are three -- two in Drupal core and one in the individual theme. Scott [3] http://drupal.org//user/1517 ------------------------------------------------------------------------ April 17, 2005 - 17:14 : Dries Scott, is right. The theme should export its available regions. Then the administrator's task is to assign blocks to regions (not to setup regions). A theme could have configurable regions, but that internal to the theme. To me, the real challenge is the UI and the interaction design. Configuring blocks could easily become a real pain (while most themes continue to use 'left' and 'right'.) Of course, we can implement all the functionality, default everything to 'left' and 'right', and worry about the UI later. This should be fairly straightforward to implement and nedjo's patch looks like a first step in the right direction. ------------------------------------------------------------------------ April 18, 2005 - 07:09 : nedjo I agree with the suggested approach of themes registering their regions. I'd see this happening when a particular theme is activiated (or upgraded). Regions would be an array of names (e.g., 'left', 'right', 'footer'). New records would be created in the region table only for region names not previously registered. Some areas I'm not clear on, or that need further work: Table naming Should a new table be 'region' or 'regions' (I've used 'region')? I don't see a convention among existing table names, some of which are singular and others plural. Default values I've kept the existing '0' and '1' ids for regions (left and right, respectively), for backward compatibility. But this means we can't use autoincrement for the region id (rid), since autoincrements seem to begin with 1. Likely we should change to autogenerated ids. Initial records Using the INSERT INTO statements as I've done for the initial region entries is probably counterproductive, since sooner or later they'll have to be dynamically generated. I was hoping this could be a preliminary patch, with the main work coming later, but likely we need to solve region registration by themes before this patch is applied. I don't have a good idea of how region registration by themes would be implemented (a hook on theme activation?), and invite suggestions or implementations. Theme system changes Besides region registration, the other change I'm seeing that would be needed in the theme system is loading blocks by region name, rather than region id. This is because the ids currently used ('0' and '1') in theory might be diffferent on a particular install. ------------------------------------------------------------------------ April 18, 2005 - 07:18 : syscrusher Instead of having themes "register" their regions, why not just add a theme API hook called them_regions() that returns an associative array of $region_name=>t($region_helptext)? This would be in keeping with other similar API functions, such as those that return what permissions apply to a module or what node types are defined by a module. Most themes are going to define only a small number of regions (two being the typical case now, but I could see five or six in a complex theme), so returning a constant array will be faster than querying SQL to obtain an array of rows. There could be (optionally, at the discretion of whoever builds this thing) another API hook like theme_region_properties($region_name) that returns an associative array with detailed info for a given region, such as extended help text with recommended usage instructions for the region. Scott ------------------------------------------------------------------------ April 18, 2005 - 07:19 : syscrusher s/them_regions/theme_regions/g ------------------------------------------------------------------------ April 18, 2005 - 08:47 : adrian Because. The most common 'theme' is a phptemplate theme. And there needs to be a generic method for specifying the regions available, in a non hook_function format.. Themes get their names from the directory in which they are contained.. when copying the theme to another directory, there must be _no_ modifications necessary to allow normal usage. This is one of the tenets of the new template system I designed. You would need a standard way to define meta-information for themes, that does not need to be modified when copied to a new directory. We are working on this in the install system work, as you need a way external of Drupal to define the module dependencies and some other things. My approach would be to add a theme.dsc text file to the directory, which would allow you to specify meta-information.
