[drupal-devel] [bug] make standard roles translatable
by stefan nagtegaal 24 Aug '05

24 Aug '05

Issue status update for http://drupal.org/node/5570 Post a follow up: http://drupal.org/project/comments/add/5570 Project: Drupal Version: cvs Component: user system Category: bug reports Priority: normal Assigned to: Anonymous Reported by: stefan nagtegaal Updated by: stefan nagtegaal Status: patch (code needs work) Indeed Cvbge.. Even in the latest CVS version 24-08-2005 this is still an issue.. It's the last 2 strings which could not be properly translated which really frustrates me, and hopefully other users.. Probably we can fix this issue when adding id's to the roles? Or by defining them as constants? <?php DEFINE('ANONYMOUS_USER', t('Anonymous user')); DEFINE('AUTHENTICATED_USER', t('Authenticated user')); ?> The pro's of the defined constants method is that we can also get rid of the 'Anonymous user'-option on the settings page, because it becomes translatable.. What do you think, will this work? stefan nagtegaal Previous comments: ------------------------------------------------------------------------ Sun, 01 Feb 2004 18:03:37 +0000 : stefan nagtegaal There are several things that would need to be fixed before we are going to release drupal 4.4. One of that is proper translation.. - The basic roles 'Anonymous user'/'Anonymous' & 'Authenticated user' aren't translatable on the following places (admin >> users / admin >> users >> roles / admin >> users >> permission / ) ------------------------------------------------------------------------ Fri, 23 Jul 2004 17:19:35 +0000 : killes(a)www.drop.org Changing title. ------------------------------------------------------------------------ Wed, 06 Oct 2004 09:53:48 +0000 : stefan nagtegaal This is still a problem.. The default roles 'Anonymous user' and 'Authenticated user' can not be translated. ------------------------------------------------------------------------ Wed, 06 Oct 2004 12:55:38 +0000 : Axel But why this bug is critical? Drupal works on such manner long time. This bug don't prevent Drupal to work. I think priority of this bug must be set as 'normal', but not 'critical'. ------------------------------------------------------------------------ Wed, 03 Nov 2004 18:53:46 +0000 : com2 I would say either committed to multilingual / localization or not. Calling it a feature seems to say "translation has a low priority". When that is the case, why all the trouble to localize? Jus drop localization and make life easier! All depends on the chosen concept of Drupal. If you choose Drupal to be multilingual / localized, then this is definitely is a bug. You cannot expect a non-english speaker to understand these special users. What happens when I just translate them in table /role/? Would it break Drupal? ------------------------------------------------------------------------ Wed, 04 May 2005 13:48:34 +0000 : schalker As I can tell, standard roles still can not be translated. Is this correct? Is there a work-around or some plan to implement this? I'd agree with the former poster com2 that this is more a bug than a feature request: I love the locale module, but I cannot see a reason why almost everything is translateable, but not the standard roles. If there is no reason for this behaviour /from a user-point-of-view/, then this is a bug, I'd say. ------------------------------------------------------------------------ Wed, 04 May 2005 14:05:33 +0000 : schalker Sorry, it's me again. I searched on and on to find a similar bug report, but I haven't found one. So as two people think this is a bug, I change the category of this issue back to "bug report". ------------------------------------------------------------------------ Tue, 09 Aug 2005 19:40:42 +0000 : Cvbge Attachment: http://drupal.org/files/issues/translate_default_roles.diff (1.84 KB) Patch not tested, but it's quite simple. I'd like to hear some thoughts about t()ing default roles (anonymous and authenticated user). ------------------------------------------------------------------------ Tue, 09 Aug 2005 20:01:02 +0000 : Cvbge Ok, this won't work, because roles are selected from db when put on admin/access. The only way I see to solve this (although it's still not clean) is to a) make default roles editable (so user can change the 'anonymous user' to something else), but not deletable b) make sure anon user and auth user have static id c) do not check in code for name, but for role id Need to think about it...

[drupal-devel] [feature] move user-selected themes out of core
by drumm 24 Aug '05

24 Aug '05

Issue status update for http://drupal.org/node/26302 Post a follow up: http://drupal.org/project/comments/add/26302 Project: Drupal Version: cvs Component: theme system Category: feature requests Priority: normal Assigned to: TDobes Reported by: Torenware Updated by: drumm Status: patch (code needs review) +1 never thought of how easy this would be with $custom_theme. drumm Previous comments: ------------------------------------------------------------------------ Mon, 04 Jul 2005 01:50:45 +0000 : Torenware Attachment: http://drupal.org/files/issues/add-user-themable-option.diff (1.86 KB) >From the forum thread How To Prevent Users From Changing The Theme. I asked: " I'm working on a module that uses organic groups. I want to allow different groups to choose different themes, but I don't want individual users to have that capability. I'm assuming that this is easy to do, but I can't find a setting. Can anybody point me in the right direction? Thanks, Rob " At sepeck's suggestion, I'm submitting a patch to do this. It's against 4.6.0, and modifies theme.inc and system.module. It creates a variable 'configurable_user_themes' which defaults to "enabled" (4.6.0's current behavior), and if activated, makes system.module remove the UI for selected a theme, and also causes theme.inc to ignore any setting for $user->theme if it exists. ------------------------------------------------------------------------ Mon, 04 Jul 2005 01:54:40 +0000 : Torenware Attachment: http://drupal.org/files/issues/add-user-themable-option_0.diff (1.86 KB) Didn't set this to "patch" initially, so I'm including the patch again. Not sure what the procedure is just yet. ------------------------------------------------------------------------ Mon, 04 Jul 2005 05:07:44 +0000 : TDobes -1 -- sorry, but I feel that we should use a different method for this sort of thing. Any theme that is checked in the admin-> themes screen should be selectable by users. Modules should get their list of available themes from list_themes(), which provides a list of all available themes, not just those that are selected for use by users. ------------------------------------------------------------------------ Mon, 04 Jul 2005 09:21:57 +0000 : Bèr Kessels I think we should simply rename the "enabled" into "selecatble". Or any better term. For the only thing tha checkbox does is enable it for users to select. It does not enable or disable the theme at all. ------------------------------------------------------------------------ Mon, 04 Jul 2005 18:56:53 +0000 : Torenware A couple of comments: To TDobbs: for most applications, you're right. But for some applications where it's important to the site that user experience is well tested, letting individual users set the theme is something of a nightmare; a problem with the theme is perceived as a problem with the site. So for /those/ sites (such as the one I'm currently working on), letting the user set the theme was APITA. Still, for a community site, I agree that the current behavior is fine. So I made the current behavior the default. To Bèr Kessels: Let me see if I understand what you mean. Currently, I've coded the UI to say in its English default: User theme settings Configurable Themes: * Disabled * Enabled Enable or disable user-configurable themes. When enabled, users can set their own theme to override the site's default theme. Would you prefer: User theme settings Selectable Themes: * Disabled * Enabled Enable or disable user-selectable themes. When enabled, users can select their own theme to override the site's default theme. I don't really want to lose the "Disable"/"Enable" part, because if you look at the current UI in 4.6, all similar settings are done that way. So using a checkbox would be inconsistent with the rest of the page. How's that? Rob ------------------------------------------------------------------------ Mon, 04 Jul 2005 21:31:14 +0000 : Bèr Kessels Attachment: http://drupal.org/files/issues/theme.png (17.19 KB) you indeed misunderstood me. We have a "enable theme" checkbox in the theme overview. That checkbos *does not enable anything* it only gives users the opportunity to select that theme. Please se the screeny (sorry, Dutch locale enabled) for what I mean. Th e second comumn. That chackbox. Just investigte its use. You will its complete and utter cruft, that checkbox. Ber ------------------------------------------------------------------------ Mon, 04 Jul 2005 23:20:55 +0000 : Torenware Ber, I have a site that may well use themes set at the group level, so unactivating the theme via admin/theme is not a great solution for me. The problem with your solution is that if a theme is deactivated, it is not available for anyone. I need multiple themes available, but need to make the rather confusing UI that appears in user/n/edit to go away. Your options will not do that. ------------------------------------------------------------------------ Mon, 04 Jul 2005 23:28:27 +0000 : Torenware Ber, /Please se the screeny (sorry, Dutch locale enabled) for what I mean. Th e second comumn. That chackbox. Just investigte its use. You will its complete and utter cruft, that checkbox./ I'm not following you. Could you please explain a bit more? Thanks, Rob ------------------------------------------------------------------------ Mon, 04 Jul 2005 23:37:13 +0000 : TDobes /I have a site that may well use themes set at the group level, so unactivating the theme via admin/theme is not a great solution for me./ Sure it is! Deactivating themes in admin->theme removes them *ONLY* from the list of themes available for users to select. It should not remove them from the list of available themes for modules to use (via. the $custom_theme variable). If themes are disappearing from the modules' lists, these are bugs in the modules and should be reported elsewhere. I was under the impression that you were writing your own module, which is why I suggested you use the list_themes function. This function returns all available themes, not just those that are selected in admin->themes. Ber has mentioned that the term "enabled" is poorly chosen and should be replaced with something else, such as "user-selectable". I agree with him. /The problem with your solution is that if a theme is deactivated, it is not available for anyone./ This is completely false. It is not available to be chosen in the "my account" screen, but it is still very readily available for use by modules through the $custom_theme variable. /I need multiple themes available, but need to make the rather confusing UI that appears in user/n/edit to go away. Your options will not do that./ Yes they do. How are you determining the list of available themes in your module? If the themes are disappearing when you deselect them from admin->themes, then your module is working improperly. ------------------------------------------------------------------------ Mon, 04 Jul 2005 23:59:25 +0000 : Torenware OK, if I'm understanding you, then indeed the UI in admin/themes is bad done enough to fool a native English speaker. What y'all from Europe make of some of the terms, I can't even guess :-) I'll see if the UI disappears if all of the items are "deactivated" makes the UI go away (and doesn't break Organic Groups...). But it sounds like the real "bug" is in the documentation. This string: / Select which themes are available to your users and specify the default theme. To configure site-wide display settings, click the "configure" task above. Alternately, to override these settings in a specific theme, click the "configure" link for the corresponding theme. / needs changing. Perhaps something like "Choose a default theme for your site, and select which themes your users can choose to override the default." For the record: I do not have a clue what "Alternately, to override these settings in a specific theme, click the "configure" link for the corresponding theme.". If someone will tell me what that means, maybe some of us can translate it into English :-) Then someone can translate it into whatever else we need to support. ------------------------------------------------------------------------ Sat, 20 Aug 2005 05:22:53 +0000 : TDobes Please see the patch I've attached to this issue [1], which renames "enabled" to "user-selectable"... this should hopefully clear up a lot of confusion. [1] http://drupal.org/node/29002 ------------------------------------------------------------------------ Sat, 20 Aug 2005 07:52:28 +0000 : robertDouglass I'd like to propose a different solution; create a "can select own theme" permission for users. I agree that there are cases where some people should be able to choose their theme and others shouldn't. Personally, I don't make many sites where you get to "skin" the site just for fun. More likely, I use theme selection for development purposes (I develop the next version of a site's theme and can switch back and forth, and so can the developer, but nobody else). If we had a permission that could be given to roles, then og group administrators could be given this permission, if I'm not mistaken. Would this fit the bill, Torenware? ------------------------------------------------------------------------ Sat, 20 Aug 2005 17:30:29 +0000 : Bèr Kessels personally I am all for removing that option alltogether. "for development reasons" is simply not a reason to leave this in. What about getting rid of this "let users select their alternative theme". And focus more on sections/themeswitchers ? ------------------------------------------------------------------------ Sat, 20 Aug 2005 18:52:03 +0000 : robertDouglass I'm not for removing it. There are a lot of efforts going forward to do things like theme an individual's blog differently (blog_theme module, I think), and this is very interesting, especially if combined with some form of theme editor. The best interface we have for choosing themes is part of the user edit page. Let's not get rid of it. What's wrong with an permission to allow users to choose their own theme? ------------------------------------------------------------------------ Sun, 21 Aug 2005 08:56:32 +0000 : Bèr Kessels There is nothnig wrong witha permission. But with the options in your profile. * Does anyone actually allow his users to choose his or her theme in the profile? I have never come across a drupal site that does this. Never! * As you state, there are loads of much better uses of personal themes, like letting a user choose a theme for his blog. Or a print theme, or a theme for better visibility. Or even a theme special for bots. sections, admin themes, etc. None of these cases benefit from the in-profile theme choice. I think this is some odd *nuke ripoff feature, that is only there, because no-one took the time to remove it. Really, have you ever seen this being used on a site? So to conclude: IMO the in-profile theme choice should go. We should focus on writing or improving modules that do advanced themeswitching. ------------------------------------------------------------------------ Sun, 21 Aug 2005 09:07:02 +0000 : robertDouglass Ok, I agree that the in-profile theme changing stuff is cruft. Better would be a module that lets users do this. It could even show up in the same place, but at least it wouldn't be in core. ------------------------------------------------------------------------ Sun, 21 Aug 2005 09:13:59 +0000 : TDobes In response to Bèr: "* Does anyone actually allow his users to choose his or her theme in the profile? I have never come across a drupal site that does this. Never! " Well, I use the feature. In fact, it was the reason I got interested in the Drupal theming system to begin with. I was extremely frustrated by users' inability to switch between chameleon styles and xtemplate templates in Drupal prior the the last major theming patch. However, I tend to agree with you that this feature could be removed from core. This sort of functionality could be added to the user profile page by a contrib module and implemented by using the $custom_theme variable. ------------------------------------------------------------------------ Sun, 21 Aug 2005 21:37:56 +0000 : Dries Agreed. Let's move this to a contributed module and let's tidy up the theme configuration page (unless I'm mistaken, the enabled-checkboxes could probably be removed?). ------------------------------------------------------------------------ Sun, 21 Aug 2005 21:43:23 +0000 : killes(a)www.drop.org Moving to cvs. I am delighted about this change. This "feature" annoyed me right from when I started to use Drupal... ------------------------------------------------------------------------ Mon, 22 Aug 2005 04:14:48 +0000 : TDobes Attachment: http://drupal.org/files/issues/no_more_user_selectable_themes.patch (5.39 KB) I've attached a patch which removes the option for selecting themes from the _user hook and the special handling of $user->theme from init_theme. While I did consider removing the "enabled" field, I decided against it. When all themes are always enabled, the number of sub-tabs of "configure" can become unmanagable. drumm's recent usability improvement [2] to the theme admin involved hiding tabs for those themes which are not enabled. Additionally, contrib modules which manipulate $custom_theme should be obtaining their list of selections by using list_themes(). Therefore, they too would benefit by displaying only those themes which have been enabled by the site admin. For example, a site admin may wish to make only certain themes available to other site developers who have the ability to switch themes in certain sections of the site. [2] http://drupal.org/node/29002 ------------------------------------------------------------------------ Mon, 22 Aug 2005 04:19:12 +0000 : TDobes Attachment: http://drupal.org/files/issues/usertheme.module.txt (3.06 KB) Here's a quick copy-and-paste module containing the code removed from core... it allows users (whom are granted the appropriate permission) to switch the theme with which they view the site. I made it as a proof-of-concept that this same functionality can easily be recreated by a standalone module.

[drupal-devel] [feature] export book as xml for formatting
by Uwe Hermann 24 Aug '05

24 Aug '05

Issue status update for http://drupal.org/node/1482 Post a follow up: http://drupal.org/project/comments/add/1482 Project: Drupal Version: cvs Component: book.module Category: feature requests Priority: normal Assigned to: puregin Reported by: BenEng Updated by: Uwe Hermann Status: patch (code needs review) Attachment: http://drupal.org/files/issues/book_30.patch (15.89 KB) Rerolled patch to improve format (diff -u -p). Uwe Hermann Previous comments: ------------------------------------------------------------------------ Sat, 05 Apr 2003 21:38:33 +0000 : BenEng Export an entire collaborative book to xml (docbook) so that it can be formatted using xslt (e.g., to rtf or pdf) and printed. It would also be nice to be able to perform the reverse. That is to import a collaborative book from an xml (docbook) file that is uploaded. ------------------------------------------------------------------------ Thu, 03 Jun 2004 00:10:41 +0000 : moshe weitzman can someone suggest an xml schema for this? i think we need a general xml schema for nodes. after that, this becomes a simple matter of nesting node elements (I think) ------------------------------------------------------------------------ Tue, 01 Feb 2005 09:42:35 +0000 : Teto Hi, Is there any news about a such feature ? All i've found about a docbook schema is here : http://docbook.sourceforge.net/projects/schema/ It seems there isn't much in the docbook cvs about that. Teto. ------------------------------------------------------------------------ Sat, 14 May 2005 09:11:53 +0000 : puregin Here's a list of the Book publishing DTDs I know about: NameNotesRef ISO 12083:1998//DTD Book//EN - this includes ISO 12093:1993//DTD Mathematics//EN Committee standard - very general. Used e.g. by University of California Press. www.xmlxperts.com/bookdtd.htm [1] DocBook Applications - widely used by Computer book publishers, e.g. O'Reilly. Good support. docbook.org [2] TEI/TEI-Lite Applications - scholarly/historical/literary documents www.tei-c.org [3] MIL-STD-38784 (CALS) Applications - Military/Govt/Enterprise publishing http://xml.coverpages.org/mil-std-38784-a1-dtd.txt [4] I'd highly recommend DocBook as a useable, technically focused, XML DTD with strong toolset support. [1] http://www.xmlxperts.com/bookdtd.htm [2] http://docbook.org [3] http://www.tei-c.org/ [4] http://xml.coverpages.org/mil-std-38784-a1-dtd.txt ------------------------------------------------------------------------ Wed, 18 May 2005 08:37:53 +0000 : puregin I'd suggest we start with something very simple. The patch which I submitted for http://drupal.org/node/1898 wraps each node in <div> tags, with a level, and a node id attribute, for printer friendly output. We can't rely in general on the contents of a node being XHTML, even if we force output through an XHTML validator such as tidy. So our best bet is to encode the entire contents of a node as CDATA. This gives us hierarchy, and encapsulated contents (of any kind - later this could also be other kinds of data or markup) This output will be valid XML, with a pretty simple DTD. It is easy to take such a file and write simple XSLT based scripts on the the client side to explode this file into a directory tree of HTML, a single HTML file, or many other formats. Importing is trickier. It's relatively easy to import an exported file, and update the nodes of the book according to the hierarchy defined by the sectional <div> elements. Importing needs to take care of structure which has changed - child nodes added, deleted, or moved. It would also be nice to have some client-side scripts to import other formats into this nested sectional <div> based format - for example, to take a directory tree of HTML fragments, and make this into an importable file. ------------------------------------------------------------------------ Wed, 01 Jun 2005 10:33:12 +0000 : puregin Attachment: http://drupal.org/files/issues/xml-export.patch (14.06 KB) This patch enables export of books as XML documents. The XML is DocBook "at the level of structure", but node contents are wrapped as CDATA, since we can't be sure that the contents are valid XML. Several other bugs/feature requests are also addressed with this patch: - Fixes bugs http://drupal.org/node/1898 http://drupal.org/node/1482 http://drupal.org/node/8049 http://drupal.org/node/1899 Should go a long way towards implementing feature request http://drupal.org/node/2062 It should also be easy to extend this to produce OPML, for example. - Adds about 170 lines, of which more than 100 are comments - Added doxygen comments - Made doxygen comment format consistent; fixed minor grammatical slips - A proper Doctype and more informative HTML element is generated for printer-friendly HTML output. - Refactored book_print() to use book_recurse(). - Refactored book_recurse(). Applies 'visitor' callback functions to nodes during weight/title order tree-traversal. The parameterized visitor callbacks can be used to generate different kinds of output. There are many other kinds of operations on books which can be implemented by writing a pre-node/post-node pair of callback functions: word-count/ statistics gathering, comparison, copying, search and replace... - Introduced book_export() which uses book_recurse() to generate DocBook-like XML to export book contents in a structured form. An md5 hash is computed for each node to help import code to decide if a node needs to be updated or not. ------------------------------------------------------------------------ Fri, 03 Jun 2005 08:29:40 +0000 : puregin Attachment: http://drupal.org/files/issues/xml-export-01.patch (14.19 KB) This updated patch adds "weight" metadata, which I forgot to capture in the previous patch. I'm not sure how much other metadata I should include. ------------------------------------------------------------------------ Fri, 03 Jun 2005 09:06:17 +0000 : puregin Attachment: http://drupal.org/files/issues/explode2dir.php (6.64 KB) The attached command-line PHP script may be useful in testing the XML export patch supplied. Assuming your local version of PHP is built with CLI support and XML parser support, you should be able to run the script against an XML export file generated by the book module with my patch. After you have installed the patch, you can select a book page, click on the 'export XML' link, and save the result as a file, say 'test.xml'. Then run the script. On my system this looks like this: % ./export2dir.php test.xml This will produce output that looks something like this: ./explode2dir.php test.xml md5: 9e8ca98c6a8be35c21f31f7937608acc weight: 1 md5: 11a1956a1592feac37abee6b469e62c8 weight: 0 md5: ed4c91279d3bed28b56899b75ccaa9aa weight: 0 It will generate a directory hierarchy, with one directory per book node. Each directory contains a file containing the node contents and a file 'nid' containing the metadata. You can check, for example, that the md5 signature of the contents match the md5 signature recorded with the metadata. Djun ------------------------------------------------------------------------ Fri, 03 Jun 2005 18:46:15 +0000 : Dries I like the approach taken in this patch! Let's tidy up the menu structure. I suggest changing book/export (docbook) book/print (plain-text) to export/docbook export/text If we add OPML-support, it would then become: export/opmlSimilarly, I suggest renaming 'export XML' to 'export DocBook XML' (or something). ------------------------------------------------------------------------ Fri, 03 Jun 2005 18:53:17 +0000 : Dries Haven't tried it but how does DocBook handle CDATA? Does it come out OK? Read: does it make sense to do it this way? ------------------------------------------------------------------------ Fri, 03 Jun 2005 23:04:40 +0000 : puregin Dries, The output XML which I've implemented is only 'DocBook-like', not true DocBook. I've been dealing with structure at the top level (book, chapter, section). I've hidden away the actual content inside a CDATA section. The XML is really intended to provide a container for export. At this point I'm trying to focus on a relatively simple way to do an export/import round trip of the current content format (text/'loose' HTML). Most people would probably not edit this using an XML editor. I think I can generate a tar/gzip archive of the directory structure I described (output of explode2dir.php) directly on the server, either by calling an external pipeline, or by using the tar/gzip PEAR extension. So the XML format I described would be useful primarily as means to do the /import/, unless we can think of a better way to import such a directory structure (perhaps via the node_import module?) How the CDATA section is handled depends on the application. Most XML editors will display this as CDATA, allow the user to edit as CDATA, and to perform edit operations such as cut/paste to convert the CDATA to other XML elements. DocBook formatting applications could do various things - ignore the CDATA; format as 'preformatted', e.g., source listing; or try to do something clever, like attempting to parse and convert the CDATA into real DocBook before proceeding. To generate true DocBook, we would have to: * emit a document type declaration * decide if we want to export complete documents (i.e., top level elements such as books, articles, set) or document fragments. The real difficulty is dealing with the /content/: to convert this into DocBook, we'd have to attempt to map (possibly not well formed) text and/or HTML into well-formed DocBook XML. This would require guessing in many cases, since text/HTML doesn't directly encode the author's intent. A problem with this would be that the content might not be returned exactly as exported in an (export/import) 'round trip' . If we want to support true DocBook, it would probably be better to do this via an input filter, similar to the PHP input filter - definitely worth pursuing, but perhaps a separate issue? I will rewrite the patch to make sure that the exported XML validates as a DocBook fragment, and punt off to people who actually want to deal with real DocBook the problem of embedding and converting content. These folks would probably not so interested in round-trip import/export, until we have native DocBook nodes, at which point many of these issues vanish (I hope :) Regards, Djun ------------------------------------------------------------------------ Sat, 04 Jun 2005 00:01:57 +0000 : Amazon As an active member of the documentation team I would greatly appreciate any ability to export and import content to and from the documentation handbooks. Drupal is slow for editing, and has some usability issues that I will be following up on. Please consider accepting this as a incremental step to assisting the documentation team and other editors. Kieran ------------------------------------------------------------------------ Sat, 04 Jun 2005 07:28:06 +0000 : Dries If the goal is to generate books, DocBook-export is key. However, if the output is only DocBook-like, it is only going to be used by a handful of people. I think the code comments should mention that it is only DocBook-like. If the goal is to import/export books, OPML might be the better choice. I think book syndication (publish/subscribe) is going to be the more popular. Either way, let's clean up the URL scheme and extend the book_help() function a bit (if not already). ------------------------------------------------------------------------ Sun, 05 Jun 2005 11:00:28 +0000 : Dries I made some changes (URL scheme) and committed this patch to HEAD. Please update your tree before making more changes. - Can you update the issues affected by this commit? - I wonder why the release info (md5-sum) isn't stored at XML attributes so it can be parsed/extracted easily. Probably DocBook-specific. - Firefox did not recognize the XML document as being XML. I think we might have to send the proper headers: drupal_set_header('Content-Type: text/xml; charset=utf-8');.

Great work Djun. ------------------------------------------------------------------------ Mon, 06 Jun 2005 09:18:58 +0000 : puregin Attachment: http://drupal.org/files/issues/xml-export-03.patch (22.3 KB) Thanks, Dries. Here is a new patch, against revision r1.299. - now generate value DocBook XML (fragments). Level 0 nodes are exported as books; level 1 as chapters, and level 2 and higher as sections. Content is still wrapped as CDATA, for the moment. I am working on code to generate proper DocBook from HTML, but this will require 1) Tidy, HTMLCorrector or something of the sort, to ensure that the HTML is well-formed XHTML; and 2) XSLT support enabled for PHP. I assume that this will need to be a packaged as a contributed module? - generate OPML (titles only) - issue Content-type: text/xml headers for XML output (DocBook, OPML) - changed URL scheme (single callback for all exports, takes export type as 1st argument) - merged book_export_html and book_export_xml into a single function book_export with 'switch()' logic to handle different output formats, to support the above URL scheme. So for example, book/export/html/154 will generate printer friendly HTML, while book/export/docbook/154 generates DocBook. - added function _book_get_depth($nid) which computes the absolute depth of a node in a book hierarchy - printer-friendly HTML is now generated with the exported node embedded to its absolute depth (e.g., level 3 nodes will always be marked-up as level 3 nodes) - changed name book_node_visitor_print -> name book_node_visitor_html - added parameter depth to 'post-node' visitor function call - fixed incorrect parameter to node_invoke_nodeapi() - changed 'view' to 'print' so as to avoid rendering book navigation in printer friendly (or other export format) output. - Added the new admin/help documentation, updated to include the XML export functionality. ------------------------------------------------------------------------ Thu, 09 Jun 2005 01:08:17 +0000 : muralik when i patch, i get this error, any clues? failed at line 321 ------------------------------------------------------------------------ Thu, 09 Jun 2005 03:11:02 +0000 : puregin I'd guess you are applying the patch to the wrong version.

[drupal-devel] form API
by Dries Buytaert 23 Aug '05

23 Aug '05

As might have seen, Adrian made the new form API available at http:// drupal.org/node/29465. I'd like to see the new form API included in core so please take the time to review/test Adrian's patch. Ideally, apply the patch and update one or more core forms to take advantage of the new form API. Like that, you help test the patch, familiarize yourself with the code, contribute back some needed changes, and you'll be able to provide constructive suggestions. Please do. Thanks. -- Dries Buytaert :: http://www.buytaert.net/

Djun puregin Previous comments: ------------------------------------------------------------------------ Sat, 05 Apr 2003 21:38:33 +0000 : BenEng Export an entire collaborative book to xml (docbook) so that it can be formatted using xslt (e.g., to rtf or pdf) and printed. It would also be nice to be able to perform the reverse. That is to import a collaborative book from an xml (docbook) file that is uploaded. ------------------------------------------------------------------------ Thu, 03 Jun 2004 00:10:41 +0000 : moshe weitzman can someone suggest an xml schema for this? i think we need a general xml schema for nodes. after that, this becomes a simple matter of nesting node elements (I think) ------------------------------------------------------------------------ Tue, 01 Feb 2005 09:42:35 +0000 : Teto Hi, Is there any news about a such feature ? All i've found about a docbook schema is here : http://docbook.sourceforge.net/projects/schema/ It seems there isn't much in the docbook cvs about that. Teto. ------------------------------------------------------------------------ Sat, 14 May 2005 09:11:53 +0000 : puregin Here's a list of the Book publishing DTDs I know about: NameNotesRef ISO 12083:1998//DTD Book//EN - this includes ISO 12093:1993//DTD Mathematics//EN Committee standard - very general. Used e.g. by University of California Press. www.xmlxperts.com/bookdtd.htm [1] DocBook Applications - widely used by Computer book publishers, e.g. O'Reilly. Good support. docbook.org [2] TEI/TEI-Lite Applications - scholarly/historical/literary documents www.tei-c.org [3] MIL-STD-38784 (CALS) Applications - Military/Govt/Enterprise publishing http://xml.coverpages.org/mil-std-38784-a1-dtd.txt [4] I'd highly recommend DocBook as a useable, technically focused, XML DTD with strong toolset support. [1] http://www.xmlxperts.com/bookdtd.htm [2] http://docbook.org [3] http://www.tei-c.org/ [4] http://xml.coverpages.org/mil-std-38784-a1-dtd.txt ------------------------------------------------------------------------ Wed, 18 May 2005 08:37:53 +0000 : puregin I'd suggest we start with something very simple. The patch which I submitted for http://drupal.org/node/1898 wraps each node in <div> tags, with a level, and a node id attribute, for printer friendly output. We can't rely in general on the contents of a node being XHTML, even if we force output through an XHTML validator such as tidy. So our best bet is to encode the entire contents of a node as CDATA. This gives us hierarchy, and encapsulated contents (of any kind - later this could also be other kinds of data or markup) This output will be valid XML, with a pretty simple DTD. It is easy to take such a file and write simple XSLT based scripts on the the client side to explode this file into a directory tree of HTML, a single HTML file, or many other formats. Importing is trickier. It's relatively easy to import an exported file, and update the nodes of the book according to the hierarchy defined by the sectional <div> elements. Importing needs to take care of structure which has changed - child nodes added, deleted, or moved. It would also be nice to have some client-side scripts to import other formats into this nested sectional <div> based format - for example, to take a directory tree of HTML fragments, and make this into an importable file. ------------------------------------------------------------------------ Wed, 01 Jun 2005 10:33:12 +0000 : puregin Attachment: http://drupal.org/files/issues/xml-export.patch (14.06 KB) This patch enables export of books as XML documents. The XML is DocBook "at the level of structure", but node contents are wrapped as CDATA, since we can't be sure that the contents are valid XML. Several other bugs/feature requests are also addressed with this patch: - Fixes bugs http://drupal.org/node/1898 http://drupal.org/node/1482 http://drupal.org/node/8049 http://drupal.org/node/1899 Should go a long way towards implementing feature request http://drupal.org/node/2062 It should also be easy to extend this to produce OPML, for example. - Adds about 170 lines, of which more than 100 are comments - Added doxygen comments - Made doxygen comment format consistent; fixed minor grammatical slips - A proper Doctype and more informative HTML element is generated for printer-friendly HTML output. - Refactored book_print() to use book_recurse(). - Refactored book_recurse(). Applies 'visitor' callback functions to nodes during weight/title order tree-traversal. The parameterized visitor callbacks can be used to generate different kinds of output. There are many other kinds of operations on books which can be implemented by writing a pre-node/post-node pair of callback functions: word-count/ statistics gathering, comparison, copying, search and replace... - Introduced book_export() which uses book_recurse() to generate DocBook-like XML to export book contents in a structured form. An md5 hash is computed for each node to help import code to decide if a node needs to be updated or not. ------------------------------------------------------------------------ Fri, 03 Jun 2005 08:29:40 +0000 : puregin Attachment: http://drupal.org/files/issues/xml-export-01.patch (14.19 KB) This updated patch adds "weight" metadata, which I forgot to capture in the previous patch. I'm not sure how much other metadata I should include. ------------------------------------------------------------------------ Fri, 03 Jun 2005 09:06:17 +0000 : puregin Attachment: http://drupal.org/files/issues/explode2dir.php (6.64 KB) The attached command-line PHP script may be useful in testing the XML export patch supplied. Assuming your local version of PHP is built with CLI support and XML parser support, you should be able to run the script against an XML export file generated by the book module with my patch. After you have installed the patch, you can select a book page, click on the 'export XML' link, and save the result as a file, say 'test.xml'. Then run the script. On my system this looks like this: % ./export2dir.php test.xml This will produce output that looks something like this: ./explode2dir.php test.xml md5: 9e8ca98c6a8be35c21f31f7937608acc weight: 1 md5: 11a1956a1592feac37abee6b469e62c8 weight: 0 md5: ed4c91279d3bed28b56899b75ccaa9aa weight: 0 It will generate a directory hierarchy, with one directory per book node. Each directory contains a file containing the node contents and a file 'nid' containing the metadata. You can check, for example, that the md5 signature of the contents match the md5 signature recorded with the metadata. Djun ------------------------------------------------------------------------ Fri, 03 Jun 2005 18:46:15 +0000 : Dries I like the approach taken in this patch! Let's tidy up the menu structure. I suggest changing book/export (docbook) book/print (plain-text) to export/docbook export/text If we add OPML-support, it would then become: export/opmlSimilarly, I suggest renaming 'export XML' to 'export DocBook XML' (or something). ------------------------------------------------------------------------ Fri, 03 Jun 2005 18:53:17 +0000 : Dries Haven't tried it but how does DocBook handle CDATA? Does it come out OK? Read: does it make sense to do it this way? ------------------------------------------------------------------------ Fri, 03 Jun 2005 23:04:40 +0000 : puregin Dries, The output XML which I've implemented is only 'DocBook-like', not true DocBook. I've been dealing with structure at the top level (book, chapter, section). I've hidden away the actual content inside a CDATA section. The XML is really intended to provide a container for export. At this point I'm trying to focus on a relatively simple way to do an export/import round trip of the current content format (text/'loose' HTML). Most people would probably not edit this using an XML editor. I think I can generate a tar/gzip archive of the directory structure I described (output of explode2dir.php) directly on the server, either by calling an external pipeline, or by using the tar/gzip PEAR extension. So the XML format I described would be useful primarily as means to do the /import/, unless we can think of a better way to import such a directory structure (perhaps via the node_import module?) How the CDATA section is handled depends on the application. Most XML editors will display this as CDATA, allow the user to edit as CDATA, and to perform edit operations such as cut/paste to convert the CDATA to other XML elements. DocBook formatting applications could do various things - ignore the CDATA; format as 'preformatted', e.g., source listing; or try to do something clever, like attempting to parse and convert the CDATA into real DocBook before proceeding. To generate true DocBook, we would have to: * emit a document type declaration * decide if we want to export complete documents (i.e., top level elements such as books, articles, set) or document fragments. The real difficulty is dealing with the /content/: to convert this into DocBook, we'd have to attempt to map (possibly not well formed) text and/or HTML into well-formed DocBook XML. This would require guessing in many cases, since text/HTML doesn't directly encode the author's intent. A problem with this would be that the content might not be returned exactly as exported in an (export/import) 'round trip' . If we want to support true DocBook, it would probably be better to do this via an input filter, similar to the PHP input filter - definitely worth pursuing, but perhaps a separate issue? I will rewrite the patch to make sure that the exported XML validates as a DocBook fragment, and punt off to people who actually want to deal with real DocBook the problem of embedding and converting content. These folks would probably not so interested in round-trip import/export, until we have native DocBook nodes, at which point many of these issues vanish (I hope :) Regards, Djun ------------------------------------------------------------------------ Sat, 04 Jun 2005 00:01:57 +0000 : Amazon As an active member of the documentation team I would greatly appreciate any ability to export and import content to and from the documentation handbooks. Drupal is slow for editing, and has some usability issues that I will be following up on. Please consider accepting this as a incremental step to assisting the documentation team and other editors. Kieran ------------------------------------------------------------------------ Sat, 04 Jun 2005 07:28:06 +0000 : Dries If the goal is to generate books, DocBook-export is key. However, if the output is only DocBook-like, it is only going to be used by a handful of people. I think the code comments should mention that it is only DocBook-like. If the goal is to import/export books, OPML might be the better choice. I think book syndication (publish/subscribe) is going to be the more popular. Either way, let's clean up the URL scheme and extend the book_help() function a bit (if not already). ------------------------------------------------------------------------ Sun, 05 Jun 2005 11:00:28 +0000 : Dries I made some changes (URL scheme) and committed this patch to HEAD. Please update your tree before making more changes. - Can you update the issues affected by this commit? - I wonder why the release info (md5-sum) isn't stored at XML attributes so it can be parsed/extracted easily. Probably DocBook-specific. - Firefox did not recognize the XML document as being XML. I think we might have to send the proper headers: drupal_set_header('Content-Type: text/xml; charset=utf-8');. Haven't checked yet.

Hi Hendrik (CC to drupal-devel), I read your "imported some language name translations I found somewhere on the web" CVS comment. Please don't forget that all content in the Drupal contrib CVS repository must be GPL'd. Did you ask the person who created that translation whether he/she released it under the terms of the GPL? You cannot simply copy any stuff you find on the web and put it into the repository. If you don't know for sure what the license of those translations are, please remove them from CVS. If those are GPL, please disregard my email. ----- Forwarded message from drupal-cvs(a)drupal.org ----- From: drupal-cvs(a)drupal.org To: drupal-cvs(a)drupal.org Reply-To: drupal-devel(a)drupal.org Subject: [contributions(DRUPAL-4-6):heeckhau] /translations/nl locale-inc.po Date: 23 Aug 2005 06:41:25 -0000 User: heeckhau Branch: DRUPAL-4-6 Date: Tue, 23 Aug 2005 06:41:25 +0000 Modified files: /translations/nl locale-inc.po Log message: imported some language name translations I found somewhere on the web Links: http://cvs.drupal.org/diff.php?path=contributions/translations/nl/locale-in… -- [ Drupal cvs list | http://list.drupal.org/ ] ----- End forwarded message ----- Uwe. -- Uwe Hermann <uwe(a)hermann-uwe.de> http://www.hermann-uwe.de | http://www.crazy-hacks.org http://www.it-services-uh.de | http://www.phpmeat.org http://www.unmaintained-free-software.org | http://www.holsham-traders.de

[drupal-devel] [bug] Put revisions in their own table
by killes 23 Aug '05

23 Aug '05

Issue status update for http://drupal.org/node/7582 Post a follow up: http://drupal.org/project/comments/add/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 (ready to be committed) Attachment: http://drupal.org/files/issues/revisions_38.patch (52.26 KB) Karoly pointed out that node_save(&$node) is nicer. @Steef: nice that you write that, but a _really_ good coder would only have needed one revision. ;p killes(a)www.drop.org Previous comments: ------------------------------------------------------------------------ Wed, 05 May 2004 16:25:27 +0000 : 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. ------------------------------------------------------------------------ Wed, 05 May 2004 17:06:35 +0000 : 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? ------------------------------------------------------------------------ Wed, 05 May 2004 17:57:48 +0000 : 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. ------------------------------------------------------------------------ Wed, 05 May 2004 18:37:29 +0000 : 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. ------------------------------------------------------------------------ Fri, 30 Jul 2004 19:49:33 +0000 : 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. ------------------------------------------------------------------------ Fri, 30 Jul 2004 19:54:36 +0000 : Nick Nassar Oh yeah... The patch is a diff against Drupal CVS ------------------------------------------------------------------------ Sat, 31 Jul 2004 00:00:08 +0000 : 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? ------------------------------------------------------------------------ Sat, 31 Jul 2004 01:11:59 +0000 : Anonymous Also I think that your upgrade path loses existing revisions. ------------------------------------------------------------------------ Sat, 31 Jul 2004 02:39:12 +0000 : 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. ------------------------------------------------------------------------ Sat, 31 Jul 2004 14:40:15 +0000 : 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. ------------------------------------------------------------------------ Mon, 23 Aug 2004 13:55:49 +0000 : 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. ------------------------------------------------------------------------ Mon, 23 Aug 2004 14:10:39 +0000 : 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. ------------------------------------------------------------------------ Mon, 23 Aug 2004 16:14:39 +0000 : 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. :) ------------------------------------------------------------------------ Mon, 23 Aug 2004 17:20:57 +0000 : 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 ------------------------------------------------------------------------ Mon, 23 Aug 2004 19:23:29 +0000 : 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. ------------------------------------------------------------------------ Tue, 26 Oct 2004 02:35:06 +0000 : 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. ------------------------------------------------------------------------ Wed, 27 Oct 2004 01:04:09 +0000 : 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 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! ------------------------------------------------------------------------ Wed, 24 Nov 2004 04:21:18 +0000 : 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 ------------------------------------------------------------------------ Sat, 11 Dec 2004 12:26:02 +0000 : 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. ------------------------------------------------------------------------ Mon, 13 Dec 2004 00:25:40 +0000 : 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).

(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. ------------------------------------------------------------------------ Tue, 14 Dec 2004 17:34:44 +0000 : Nick Nassar If you need any help getting those things fixed, just let me know. ------------------------------------------------------------------------ Tue, 14 Dec 2004 17:50:30 +0000 : 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.

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'.

That is, by duplicating it, we save expensive joins on the node_revisions table. Due to this fact, this patch is actually a performance improvement. A note about updating contrib module: Strictly speaking they wouldn't need to be updated. They only need to if their authors decide that their info should be available for revisioning. The upgrade path for forum.module in my update.inc patch (+ the forum patch) should show you what needs to be done. I will write a note for the update page once the patch hits core. ------------------------------------------------------------------------ Sun, 24 Apr 2005 21:21:19 +0000 : killes(a)www.drop.org Attachment: http://drupal.org/files/issues/revisions_25.patch (60.38 KB) Updated to cvs. Dries: Based on some remarks in #drupal this is the last update I am going to do.

I've only started looking through it. I noticed one little typo, affecting updates. A patch to your last patch is attached. I'm running with the revision patch on my dev server now happily. I like the concept. What happens if you click 'stop' on your browser in the middle of a MySQL "transaction"? I assume that kills the connection to MySQL, and the lock is freed? But this then leaves changes only partially applied? What exactly does locking/unlocking the tables buy us in MySQL? I don't see anywhere that we detect if an apply fails part way through, and thus roll back...? What am I missing? ------------------------------------------------------------------------ Sat, 30 Apr 2005 07:11:28 +0000 : Dries Jeremy: many of us are worried about the performance ramifications this patch introduces. Early experiments showed a small performance improvement (while a performance regression might be expected). More performance reports from large sites like kerneltrap.org will certainly help this patch. Mind to do a quick performance comparision and to report back with some numbers? Thanks. ------------------------------------------------------------------------ Sat, 30 Apr 2005 12:38:02 +0000 : Jeremy(a)kerneltrap.org Dries: I'm not running HEAD on kerneltrap, so this really isn't a possibility. Furthermore, until I understand why we're locking tables, I don't like it. The idea of revisions in their own tables is great. The idea of locking tables to get (without any obvious benefit) there really worries me. ------------------------------------------------------------------------ Sat, 30 Apr 2005 14:16:01 +0000 : killes(a)www.drop.org @Jeremy: Thanks for looking at the patch! Also for catching the typo. :) Did you try to upgrade your database? If yes, how did it go? One of Dries' concerns is the complexity of the upgrade. How many nodes and revisions did the db have? About database locking: This part of the patch was created by Nick and I simply continued to use it. Maybe the code should rather be: if(db_begin_transaction(array('{node}', '{node_revisions}', '{watchdog}', '{sessions}', '{files}'))) { db_query($node_query, $node_table_values); db_query($revisions_query, $revisions_table_values); db_commit_transaction(); ... } The idea is probably to avoid two updates at the same time. I don't think the locking helps if you abort the script at an inconvenient time. Rollbacks aren't implemented in all mysql versions. We could omit the db locking if deemed inappropriate. Maybe Nick can explain his ideas behind this. @Dries: I wonder who the "many of us" are. They certainly haven't spoken to me. Moshe had some reservations about the upgrade path and project module, but the time that project module abused revisions to store issue updates was long ago and his reservations were resolved. Nobody else (besides you of course and now Jeremy) has voiced reservations in a way that was audible to me. If you grep through the patch you will notice that there are only four queries which have a join on the node_revisions table. Two of them are in node_load and in the other cases the join replaced a join on the node table. The two queries in node_load are the only ones that have both a join on the node and the revisions query. Thus, loading of individual nodes might become somewhat slower. All other queries will be faster since the node table is now much smaller. Also, node loading does not have to be slower, it depends on your node table. If you had a lot of revisions and thus a large table, then the new scheme will make your queries actually faster since we do not load the revisions on each and every node load anymore. If you didn't have many revisions your node_load migth be somewhat slower. WRT to the update script Karoly pointed out that we could use multiple insert queries instead one query per revision. This would probably make the update somewhat faster. I am willing to work on this iff you declare that you will commit the patch afterwards. I'd need to know if this will work on pgsql and on all supported mysql versions before I work on it. About locking: Database locking is dog slow, at least on mysql. I was using locks in an earlier version of the upgrade script but had to remove it for (serious!) performance reasons. ------------------------------------------------------------------------ Mon, 09 May 2005 15:07:34 +0000 : killes(a)www.drop.org Attachment: http://drupal.org/files/issues/revisions_26.patch (46.45 KB) Ok, another update, cause I need it myself. I've left out the transaction stuff for now. It is in principle unrelated to this patch and should be discussed elsewhere. This also makes the patch smaller and easier to review (hint, hint). ------------------------------------------------------------------------ Mon, 09 May 2005 20:32:09 +0000 : killes(a)www.drop.org The patch contained the update functions twice. ------------------------------------------------------------------------ Mon, 09 May 2005 20:32:26 +0000 : killes(a)www.drop.org Attachment: http://drupal.org/files/issues/revisions_27.patch (39.05 KB) The patch contained the update functions twice. ------------------------------------------------------------------------ Mon, 09 May 2005 21:23:06 +0000 : Dries Got one error during the upgrade path: ALTER TABLE {book} ADD PRIMARY KEY vid (vid) FAILED ------------------------------------------------------------------------ Mon, 09 May 2005 21:26:19 +0000 : killes(a)www.drop.org This had happend to me as well, when I tested this patch. The reason is that for some reason the vid is not unique. Most likely there are some entries with vid = 0 in there. Can you check which node types those have? it always was an error in the test database. See: http://drupal.org/node/7582#comment-20678 ------------------------------------------------------------------------ Mon, 09 May 2005 21:27:06 +0000 : Dries Actually, I got 2850 errors during the upgrade. Some of these: sprintf() [function.sprintf]: Too few arguments in drupal-cvs/includes/database.inc on line 154. Some of these: Query was empty query: in drupal-cvs/includes/database.mysql.inc on line 66. And this: Unknown table 'n' in field list query: SELECT n.nid, n.vid FROM node INNER JOIN files f ON n.nid = f.nid in drupal-cvs/includes/database.mysql.inc on line 66. :-) ------------------------------------------------------------------------ Mon, 09 May 2005 21:29:19 +0000 : Dries Or this: user error: Unknown column 'log' in 'field list' query: SELECT parent, weight, log FROM book WHERE nid = 1 in drupal-cvs/includes/database.mysql.inc on line 66 ------------------------------------------------------------------------ Mon, 09 May 2005 21:52:12 +0000 : Dries The time required to generate my main page went from 902 ms (before upgrade) to 2139 ms (after upgrade). The time required to generate a forum listing (?q=forum/x) went from 1872 ms (before upgrade) to 2874 ms (after upgrade). Maybe this is because my database is not consistent as the result of the upgrade errors (yet I don't see any errors on the pages I benchmarked). ------------------------------------------------------------------------ Tue, 10 May 2005 00:24:38 +0000 : killes(a)www.drop.org Attachment: http://drupal.org/files/issues/revisions_28.patch (53.47 KB) Ok, let me get to this from the bottom to the top: - my test runs indicated a different development wrt timing. If I had gotten your results, I had stopped working on this long ago. So your results are wrong for some reason. - user error: Unknown column 'log' in 'field list' Wasn't my day, the book patch got lost. It is contained now. First -R the old patch, then apply this one. - Unknown table 'n' in field list query: Walkah found this, but I forgot to fix it. Fixed now. - I've no idea where the other queries come from. I am hoping that either your test db is borken or they are follow ups from the other ones. If you let me have your test db, I'll try some debugging. Thanks for wasting your time, too. ------------------------------------------------------------------------ Tue, 10 May 2005 05:07:31 +0000 : Dries I double-checked and the numbers don't seem to lie. I'll test some more after work on another machine to make sure it is not platform-specific. ------------------------------------------------------------------------ Wed, 11 May 2005 03:32:47 +0000 : killes(a)www.drop.org Attachment: http://drupal.org/files/issues/revisions_29.patch (54.83 KB) Ok, here I am again. What I did: 1) Ask Dries to let me have drupal.org database 2) get 400MB of SQL inserts... 3) take 23 minutes to import said data 4) Remove all image and project nodes (don't want to install their modules), 11765 nodes left 5) back up data 6) take tests on non-cached /node page (as anonymous user). ab results: -c 1 -n 25: Requests per second: 1.29 [#/sec] (mean) Connection Times (ms) min mean[+/-sd] median max Total: 663 775 179.7 689 1264 7) Do the same for the tracker page: Requests per second: 0.83 [#/sec] (mean) Total: 1182 1199 7.4 1199 1217 8) Apply my patch (rev. 28). 9) run db update and hold breath 10) update times out... 11) play back backup from 5) 12) wait 13) getting annoyed and removing cache, watchdog, and accesslog before playing in backup. 14) wait again. Understand why Dries doesn't try this patch often. Maybe a smaller DB would do for testing? 15) wait more. get really annoyed. 16) Set time limit to 18000 in update.php 17) try again 18) fails again before the second update is completed. 19) curse. 20) delete search stuff from db. Ooops, sooo much smaller... 21) import again, below 2 minutes... 22) rewrite to use extended insert. Found a bug. 23) still does not complete. Mysql logging to the rescue! 24) tid = 0? Not good. 25) Well, the update works fine till node 10834. 5595 nodes done, 6136 to go. 26) Writing shell based update script. Discovery: 24MB aren't enough. Hopefully 64 are. Nope. extended inserts for revisions are apparently not the brightest idea: Huge memory consumption. Hmm, no, all updates got through. Selecting the revisions to put them into old_revisions table screwed it. Learned about CREATE TABLE old_revisions SELECT syntax. Yay! finally. 24 MB are just not enough the update.php script seems to still break. 27) Benchmarks! /node Requests per second: 1.54 [#/sec] (mean) Connection Times (ms) min mean[+/-sd] median max Total: 632 649 40.5 636 791 /tracker Requests per second: 0.86 [#/sec] (mean) Total: 1119 1165 65.8 1160 1461 Ok: So we get an improvement for many node_loads, but none for simple selects from node. More tests can be done. 28) roll new patch Ain't Drupal fun? ------------------------------------------------------------------------ Wed, 18 May 2005 13:38:05 +0000 : Dries I did another round of tests on _another_ machine and it is not looking good: Before upgrade After upgrade ?q= (main page) 218 ms/request 340 ms/request ?q=forum (forum overview) 754 ms/request 1520 ms/request ?q=about (book page) 375 ms/request 5400 ms/request The upgrade process itself gave me a number of 'query was empty' and 'sprintf(): too few arguments' reports. Everything seems to work fine though. Looking at the ?q=about page, I see that the following query is executed twice _and_ that each time, it take more than 2 seconds to complete: SELECT n.nid, n.title, b.parent, b.weight FROM node n INNER JOIN book b ON n.vid = b.vid WHERE n.status = 1 AND n.moderate = 0 ORDER BY b.weight, n.title; --8 SHOW INDEX FROM book; +-------+------------+-------------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+ | Table | Non_unique | Key_name | Seq_in_index | Column_name | Collation | Cardinality | Sub_part | Packed | Null | Index_type | Comment | +-------+------------+-------------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+ | book | 1 | book_parent | 1 | parent | A | 92 | NULL | NULL | | BTREE | | | book | 1 | nid | 1 | nid | A | 369 | NULL | NULL | | BTREE | | +-------+------------+-------------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+ 2 rows in set (0.00 sec) The book module does not appear to have a primary key? Sounds like a bad idea so I added one: mysql> ALTER TABLE book ADD PRIMARY KEY nid (nid); Query OK, 369 rows affected (0.02 sec) Records: 369 Duplicates: 0 Warnings: 0 Next, I wanted to make the vid column a unique key in all node tables: mysql> ALTER TABLE node ADD UNIQUE vid (vid); Query OK, 20392 rows affected (0.81 sec) Records: 20392 Duplicates: 0 Warnings: 0 mysql> ALTER TABLE book ADD UNIQUE vid (vid); ERROR 1062: Duplicate entry '0' for key 2 mysql> ALTER TABLE forum ADD UNIQUE vid (vid); Query OK, 10806 rows affected (0.10 sec) Records: 10806 Duplicates: 0 Warnings: 0 As you can see, it fails for the book table which makes me believe there is some inconsistent data ... I set out to fix that: mysql> SELECT nid, COUNT(nid) AS vids FROM book GROUP BY vid HAVING vids > 1; +-----+------+ | nid | vids | +-----+------+ | 871 | 2 | +-----+------+ 1 row in set (0.00 sec) mysql> SELECT title FROM node WHERE nid = 871; Empty set (0.00 sec) mysql> DELETE FROM book WHERE nid = 871; Query OK, 1 row affected (0.00 sec) mysql> ALTER TABLE book ADD UNIQUE vid (vid); Query OK, 368 rows affected (0.01 sec) Records: 368 Duplicates: 0 Warnings: 0 Looks like everything is well now. Ran some new benchmarks: Before upgrade After upgrade With indices ?q= (main page) 218 ms/request 340 ms/request 336 ms/request ?q=forum (forum overview) 754 ms/request 1520 ms/request 1531 ms/request ?q=about (book page) 375 ms/request 5400 ms/request 475 ms/request Unfortunately, we're still slower than the original code. ------------------------------------------------------------------------ Wed, 18 May 2005 21:53:31 +0000 : killes(a)www.drop.org Dries, thanks for testing it again. I do think the broken queries you observer have something to do with the bad performance after the update. Please log the queries any I will have a look at them. I've never seen any such queries. My update script also tries to create the appropriate indices, but it will of course fail if the database contains cruft. the indices for the forum are probably missing, too. I am still convinced that the patch is core worthy. ------------------------------------------------------------------------ Thu, 19 May 2005 04:36:09 +0000 : Dries It wouldn't hurt if more people would benchmark this patch. The patch's current performance worries me. Did you check your watchdog messages after upgrading the drupal.org database? Depending on your settings, errors might only be shown in the watchdog. I'll look into the remaining glitches as time permits. Thanks for your persistence in keeping this patch up-to-date. :) ------------------------------------------------------------------------ Thu, 19 May 2005 11:59:22 +0000 : killes(a)www.drop.org Dries: Can you please let me have your updated database? I want to have a look at it and try my own benchmarks with it. And yes, if I did learn something on this project is how to be persistant. ;) ------------------------------------------------------------------------ Fri, 24 Jun 2005 16:25:34 +0000 : killes(a)www.drop.org Here is an idea that occurred to me: The problem with the upgrade process is that keeping the existing revisions requires a lot of work to do. This generates a huge amount of sql queries for a large database and also requires a huge amount of memory. My suggestions is to let update.php only handle the basic upgrade, ie without old revisions. An additional module could be created that would implement a cron based approach to upgrading old revisions one node at a time. it could expose a hook to let contrib modules do their own upgrades. Dries, what do you think? (I am writing "Dries" because he seems to be the only one who is interested in getting this into core...) ------------------------------------------------------------------------ Fri, 24 Jun 2005 22:25:11 +0000 : Junyor Killes: I'm also interested in seeing this hit core. What about adding something to legacy.module to do it? ------------------------------------------------------------------------ Sun, 26 Jun 2005 21:14:54 +0000 : chx This is a sensible approach. Maybe this is the _only_ sensible approach. I have a little problem though: while the conversion is running somehow both revision handlers should be available. ------------------------------------------------------------------------ Sun, 26 Jun 2005 22:16:21 +0000 : killes(a)www.drop.org hehe, one only has to whine and bug enough and one gets some feedback. ;) @junyor: legacy.module would be a good place. my current idea is to auto-enable it in update.php and then disable it again in legacy_cron after all nodes are updated.. ;) @chx: When somebody wants to look at revisions of a node that node could be auto-updated. The only problem are contrib modules: they's need to have some hook in order to update their own data. When somebody looks at the revisions of a node than cannot be updated because the contrib module in question has no such hook, we can optionally let the user discard old revisions I guess. Dries, what do you think? ------------------------------------------------------------------------ Mon, 25 Jul 2005 16:48:51 +0000 : killes(a)www.drop.org Attachment: http://drupal.org/files/issues/revisions_30.patch (53.13 KB) Sooooo; I've updated this patch once again. Dries didn't like my idea of legacy updates so we will have an option to discard old revisions in case the update should prove difficult. Always keep a backup. ------------------------------------------------------------------------ Mon, 25 Jul 2005 17:31:12 +0000 : Bèr Kessels can we please accept and commit this patch? We can iron out any issues later. This patch is just far too big and complex to be perfect-at-once. ------------------------------------------------------------------------ Mon, 25 Jul 2005 19:22:50 +0000 : Dries @Ber: no, we can't commit this patch blindly. Data loss is a much bigger problem than a syntax error or other code glitch. We can break Drupal but we can't break their data. I've spent quite a bit of time testing the previous version of this patch and noticed significant performance degradation. Tell me, Ber, why can't you test this patch first? ------------------------------------------------------------------------ Mon, 25 Jul 2005 19:40:37 +0000 : Bèr Kessels I was not referring to not testing it. If it is just the upgrade path that proves to be cumbersome, then why can we not fix it afterwards, I.e. when everyone has had a good chance to look at it. Testing such a huge patch requires a lot of work. something no-one just does in his spare hours. We had discussions before to deal in a slightly different way with big changes; to commit them quicker and to leave the ironing out of any left overs for the community. I hooked into that discussion here. For two reasons. One is that Gerhard has spent numerous hours on maintaining this patch. The other one is that the community can be of help with ironing out issues in such a large change, much better than that Gerhard can do on his own. And yes, dataloss is very bad, but no-one should loose data, when he/she followed the instructions (backing up)... ------------------------------------------------------------------------ Mon, 25 Jul 2005 20:00:38 +0000 : Dries Ber: applying this patch takes 15 seconds. Whether I apply this patch for you, or whether you apply it yourself, it will hardly reduce the 'testing cost'. The problem is that data loss can be subtle; it might go unnoticed for a couple days. Make no mistake, I'd like to see this patch committed ASAP, but it warrants some testing. Let's test/benchmark it and commit it. ------------------------------------------------------------------------ Mon, 25 Jul 2005 20:55:03 +0000 : drumm The upgrade script already takes a long time to execute and does not provide feedback to the user about how it is doing. I plan on making the upgrade script able to spread the updates across multiple page views and give user feedback showing that progress is being made. This will hopefully make the speed of this update a moot point. I am working on this for my dayjob, CivicSpace, so it should get done "real soon now", but it should be expected to take awhile (smallish number of weeks). Please make comprimises if necessary. ------------------------------------------------------------------------ Wed, 27 Jul 2005 17:38:57 +0000 : killes(a)www.drop.org Attachment: http://drupal.org/files/issues/revisions_31.patch (48.78 KB) @drumm: the timeout isn't usually the problem. Memory consumption is. I'll look into doing the updates in chunks of 1000 nodes or so. Clousseau found a bug in the patch, updated. ------------------------------------------------------------------------ Thu, 28 Jul 2005 18:28:08 +0000 : moshe weitzman Even if the upgrade issues are resolved, we have to figure out why this patch is slowing down drupal (according to benchmarks posted here). ------------------------------------------------------------------------ Fri, 29 Jul 2005 07:51:45 +0000 : Dries We can't proceed without some additional benchmarking. I already benchmarked it on two machines (see comments above), and I'll benchmark it again after August 10. The performance impact of this patch worries me so if two other people could test and benchmark this patch extensively, that would come a long way. August 10 is close to the code freeze so some help is necessary. If Gerhard/killes reviewed/tested one of your patches, it is time to return the favor ... ------------------------------------------------------------------------ Fri, 29 Jul 2005 15:40:31 +0000 : Jose A Reyero After looking at the patch I'm not really surprised this slows down everything. I thought that the reason why we wanted revisions in their own table was in the first place to have a simpler -and faster- node table. But this patch: - Adds fields and complexity not only to the node table but also to all the main tables for data - Needs additional joins just to retrieve single nodes (which is done many times for a typical main page) - Does away with encapsulation of the revision functionality requiring other modules to handle revissions related data. So please, please, please: - Make revisions table only needed when actually using revisions - Keep that old nice thing of hiding revisions system from other modules - And what's so bad with serializing data anyway? I agree that usually there are better ways to store data. But this is one of the cases where serialization does make sense. Not the current huge serialized field, but only a new table with one serialized node per row. - In general, do it much simpler. This is way too complex and it removes more functionality than it adds. In just four words: keep it simple, please. ------------------------------------------------------------------------ Fri, 29 Jul 2005 21:25:26 +0000 : killes(a)www.drop.org Attachment: http://drupal.org/files/issues/revisions_32.patch (51.27 KB) Patch updated (v31 was buggy, and there was an update to updates.inc). I've had a discussion with Jose and he will maybe do some testing over the weekend. John is also doing some testing as we speak. ------------------------------------------------------------------------ Sat, 30 Jul 2005 16:06:59 +0000 : Nick Nassar It has been exactly one year since I first submitted this patch. You know what that means: *old patch party in IRC!* Virtual beers on me! w00t! ------------------------------------------------------------------------ Sat, 30 Jul 2005 16:08:33 +0000 : Jose A Reyero Hi again. I had a talk with killes -I have to say he enlightned me about this- and also did some testing. Sorry but I dont have a good set up to provide benchmarks. Here are my conclusions -and also some explanation for the varied results abt performance: - This is faster for simple node listings - This is slower for full node/load ....thus the performance increase/decrease for a given page should depend on the relation between the number of simple node listings (usually blocks) and the number of nodes displayed in the main page. I've also experienced some trouble with attachments -not re-created when creating a new revision- and book relations, same. I'm not sure I like this new "feature" of creating a new revision every time you rollback an old one -in Drupal 4.6 this seems not to happen. Besides these details, I think this patch is good enough -and quite a powerful approach actually- though I still feel it's bit too complex when simply dealing with nodes -without revisions-, which is what we do most of the time, and complexity will be even higher with contrib modules using still more tables, not to mention flexinode -versioning info will have to be scattered everywhere in the db. So this is not a +1 nor -1. On one side I think this is powerful. On the other side I feel this is too complex and really, it's more than I need. I would be happy with a 'revision' table having: nid, vid, data(serialized), that you can forget about when not using revisions. ------------------------------------------------------------------------ Sat, 30 Jul 2005 19:16:41 +0000 : Nick Nassar On a much more serious note that my last comment, unless I'm missing something, you've introduced a subtle bug into this patch since I left it. A and B are both updating revision 5 of a node. A calls db_next_id() and gets a revision id of 6 B calls db_next_id() and gets a revision id of 7 B updates the node's revision to 7 B adds revision 7 to the revision table A updates the node's revision to 6 A adds revision 6 to the revision table Now, you have a situation where the current revision (6) isn't actually the last revision(7). For some uses, that's not a big deal, but in the case of wikis, which is what I originally hoped to use this patch for, it creates problems. ------------------------------------------------------------------------ Mon, 01 Aug 2005 00:04:14 +0000 : killes(a)www.drop.org Attachment: http://drupal.org/files/issues/revisions_33.patch (51.27 KB) Updated the patch. updates.inc was changed and chx found a typo. @Nick: I don't think the issue is due to this patch. Drupal has currently no mechanism to not let people commit a new version of the same node, whether with or without revisions. drupal_next_id ensures that the revision IDs are unique and the later revisions will be the current one. Which revision is the current one does not depend on order of the version ID, btw. @Jose: what exactly were your problems with uploads? what do I need to do to reproduce? ------------------------------------------------------------------------ Mon, 01 Aug 2005 11:33:56 +0000 : Jose A Reyero Sorry, I dont know what I did the other day but I cannot reproduce it either :-) I applied this new patch. Problems I'm having now (Testing with "stories") - Book outline is gone after creating a new revision - I cannot delete attachments (not sure it is related to your patch or to something else) - Usage of the log message: Is that mensage intended for revisions or only for book outlines? Currently the field is displayed only for outlines but shown in the revision tab Btw, the db update failed for me in patch 32, so I did it manually. I didnt do a db update again after rolling back v32 and applying v33 -should I? ------------------------------------------------------------------------ Sun, 14 Aug 2005 16:03:41 +0000 : killes(a)www.drop.org Jose, thanks a lot for testing! "- Book outline is gone after creating a new revision" Sounds like a bug, it should not. "- I cannot delete attachments (not sure it is related to your patch or to something else)" Another bug "- Usage of the log message: Is that mensage intended for revisions or only for book outlines? Currently the field is displayed only for outlines but shown in the revision tab" Log messages are possible for nodes of type book and page as well as all nodes that are put into the book. Log messages can be added for any node type, the module author should implement those. "Btw, the db update failed for me in patch 32, so I did it manually. I didnt do a db update again after rolling back v32 and applying v33 -should I?" No, the db update should be the same. I will try to fix the bugs you found. WRT the db update I've got an announcement to make: I will not migrate old revisions. Why? 1) it is a rather complicated process that requires a lot of memory and is likely to give people on cheap hosting trouble. 2) testing it takes a lot of time. 3) I don't personally need it I will still move old revisions to an old_revisions table from where they can be converted by a later update or a custom script. ------------------------------------------------------------------------ Tue, 16 Aug 2005 21:34:43 +0000 : killes(a)www.drop.org Attachment: http://drupal.org/files/issues/revisions_34.patch (52.92 KB) Ok, here is incarnation No. 34 of this patch. Dries agrees with me that we can put the revision rescue operation into a later update, possible using Drumm's installer. The patch fixes the issue with the file uploads not being deletable, I could not reproduce the problem with the outlines. ------------------------------------------------------------------------ Sat, 20 Aug 2005 13:33:40 +0000 : killes(a)www.drop.org Attachment: http://drupal.org/files/issues/scripts.tar.gz (4.39 KB) I've started to do some performance testing. I created a script that creates nodes that have revisions according to the new system. A node has a 50% chance to have a revision and then an equal chance fro between 1 and 25 revisions. I've created a database with 50 nodes and 500 comments, 7 vocabs and 100 total taxo terms. I've also created a script to convert these revisions to the old format (much easier than the other way around). Initial tests didn't show a significant change for /node. I'll try with more nodes and /tracker. Attached are the two scripts in a tarball. They need to be run against the patched install. Also included are the two preliminary results. ------------------------------------------------------------------------ Sat, 20 Aug 2005 15:16:04 +0000 : killes(a)www.drop.org I've now created a databse which has 1000 nodes and each node has 50 or 51 revisions. I have no taxo terms assigned and no comments (those parts didn't change). I am only using stories and pages. I am now fairly confident that this patch is a performance improvement for this kind of setup. for the new patch on the /node page I get Requests per second: 0.27 [#/sec] (mean) Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.0 0 0 Processing: 3592 3648 56.9 3640 3985 Waiting: 3573 3626 55.1 3620 3949 Total: 3592 3648 56.9 3640 3985 for the old one I get: Requests per second: 0.23 [#/sec] (mean) Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.0 0 0 Processing: 4247 4297 64.0 4286 4657 Waiting: 4156 4263 65.3 4253 4624 Total: 4247 4297 64.0 4286 4657 For the tracker the results are even better: old: Requests per second: 2.00 [#/sec] (mean) new: Requests per second: 3.64 [#/sec] (mean) Anybody interested in obtaining this database can mail me. It is 60MB (gzipped). ------------------------------------------------------------------------ Sat, 20 Aug 2005 16:33:26 +0000 : killes(a)www.drop.org Ok, I've now deleted the revisions and only kept the current one. The initial tests showed that the performance of the patch was miserable. then I remembered that I had shreddered the revisions table and did a mysql optimization. Now the results are as follows: /node: Requests per second: 3.19 [#/sec] (mean) Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.0 0 0 Processing: 275 312 44.3 290 499 Waiting: 255 291 44.1 268 479 Total: 275 312 44.3 290 499 Requests per second: 3.18 [#/sec] (mean) Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.0 0 0 Processing: 274 314 42.4 292 407 Waiting: 255 294 42.0 273 388 Total: 274 314 42.4 292 407 The lower one is the new system, there is no difference considering statistics. /tracker old: Requests per second: 3.72 [#/sec] (mean) Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.0 0 0 Processing: 238 268 33.8 249 332 Waiting: 219 247 33.3 230 313 Total: 238 268 33.8 249 332 new: Requests per second: 3.77 [#/sec] (mean) Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.0 0 0 Processing: 240 264 29.8 250 324 Waiting: 221 244 29.0 229 305 Total: 240 264 29.8 250 324 Same applies, no real difference. So, as soon as somebody tests the upgrade path the patch should be committed. ------------------------------------------------------------------------ Sat, 20 Aug 2005 17:18:39 +0000 : killes(a)www.drop.org Attachment: http://drupal.org/files/issues/revisions_35.patch (55.51 KB) Ok, I coudl hear them in advance "1000 nodes without revisions are not sufficient". Well, here are results for 30000 nodes without revisions. /node new: Requests per second: 0.45 [#/sec] (mean) Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.0 0 0 Processing: 2162 2202 58.9 2188 2485 Waiting: 2143 2182 54.1 2169 2413 Total: 2162 2202 58.9 2188 2485 old: Requests per second: 0.43 [#/sec] (mean) Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.0 0 0 Processing: 2319 2346 77.6 2332 2761 Waiting: 2223 2324 79.0 2311 2742 Total: 2319 2346 77.6 2332 2761 One could argue that the new approach s slightly faster. I'd like to see mroe results to believe it, but it is pretty clear it isn't slower. /tracker new: Requests per second: 0.41 [#/sec] (mean) Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.0 0 0 Processing: 2330 2418 116.9 2403 3194 Waiting: 2302 2397 117.7 2382 3175 Total: 2330 2418 116.9 2403 3194 old: Requests per second: 0.39 [#/sec] (mean) Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.0 0 0 Processing: 2496 2548 50.1 2536 2841 Waiting: 2477 2528 50.0 2518 2822 Total: 2496 2548 50.1 2536 2841 Statistically insignificant differences. All those tests where done with ab and as user No 1. model name : Intel(R) Celeron(R) CPU 2.40GHz 512MB RAM Besides the differences for revisions the change in served pages with different configurations is interesting. A new version is attached. node_save now returns the complete node (not only the nid). ------------------------------------------------------------------------ Mon, 22 Aug 2005 20:13:52 +0000 : killes(a)www.drop.org Attachment: http://drupal.org/files/issues/revisions_36.patch (55.66 KB) Ok, here is version 36 which incorporates today's changes in cvs. It also changes the upgrade path. I was trying my old solution and had to up my php mem limit to 80 MB in order to get it to run through. I hope this one is better but it needs testing. ------------------------------------------------------------------------ Mon, 22 Aug 2005 22:46:38 +0000 : killes(a)www.drop.org Attachment: http://drupal.org/files/issues/revisions_37.patch (52.29 KB) Ok, I've now moved _all_ of the heavy lifting to mysql. pgsql need to catch up. No problems with either time out or memory limit anymore. Since pgsql plays catch-up all the time, I set it to "ready to be committed". ------------------------------------------------------------------------ Tue, 23 Aug 2005 11:45:59 +0000 : stefan nagtegaal I could apply the patch on my localhost, and did not seen any errors nor disfunctioning drupal features while creating, revising, editing or deleting nodes.. So, +1 for this patch qua implementation it makes sense. Unfortunatly I chaven't got a clue howto benchmark, so that's for another person. @Gerhard: I really think you are a great person by rewriting this patch over and over again, untill Dries decides it is good enough to get in to the trunk. I doubt about the fact if there are more persons in our community who are like you.. People who would revise their patch 37 times, and even after that still open for discussion.. Gerhard, I think you are a great example of how a real coder should do it.. I think we can all learn from you..

[drupal-devel] [bug] PG_QUERY ERROR - LOCK TABLES - IMPLEMENTATION FAULT.

Issue status update for http://drupal.org/node/22911 Post a follow up: http://drupal.org/project/comments/add/22911 Project: Drupal Version: cvs Component: database system Category: bug reports Priority: critical Assigned to: Anonymous Reported by: kinai Updated by: Cvbge Status: patch (ready to be committed) Attachment: http://drupal.org/files/issues/locks_1.diff (2.81 KB) Worked, yet not worked ... This version does not use <?php db_query("{$table}" ) ?> syntax. I promise I won't do that again! Cvbge Previous comments: ------------------------------------------------------------------------ Sun, 15 May 2005 14:34:48 +0000 : kinai I get this error : Warning: pg_query() [function.pg-query]: Query failed: ERROR: syntax error on or near "cache" at character 13 in /var/www/drupal/includes/database.pgsql.inc on line 45 Fatal error: ERROR: syntax error on or near "cache" at character 13 query: LOCK TABLES cache WRITE in /var/www/drupal/includes/database.pgsql.inc on line 62 Someone could solve this problem ? Thanks kinaï ------------------------------------------------------------------------ Sun, 15 May 2005 15:19:26 +0000 : kinai The SQL Command : LOCK TABLES like used in bootstrap.inc is only specified for MySQL, not for PostgreSQL. The UNLOCK TABLES SQL command is not implemented in PostgreSQL. Someone could solve this problem ? Thanks, Kinaï ------------------------------------------------------------------------ Sat, 28 May 2005 23:34:03 +0000 : bd_csmc this issue still exists, i've verified it on a fresh cvs install w/ pgsql 8 ------------------------------------------------------------------------ Sat, 28 May 2005 23:39:52 +0000 : bd_csmc i fixed the problem in my installation, by changing the syntax to: LOCK TABLE {cache} it's table, not tables. and i dropped the 'write' bit. furthermore, pgsql does not support the UNLOCK command, so i had to comment the unlock tables command. unless there are more lock/unlock commands elsewhere in the code, this works fine for me. according to pgsql docs, UNLOCK is automatically performed at transaction end, which is why there is no such command. ------------------------------------------------------------------------ Fri, 19 Aug 2005 11:29:25 +0000 : Cvbge Attachment: http://drupal.org/files/issues/locks.diff (2.91 KB) The patch adds two functions to lock and unlock tables. ------------------------------------------------------------------------ Tue, 23 Aug 2005 12:57:43 +0000 : Cvbge Attachment: http://drupal.org/files/issues/locks_0.diff (2.8 KB) Updated, without unnecessary changes. ------------------------------------------------------------------------ Tue, 23 Aug 2005 13:07:18 +0000 : chx Cvbge says he tested pgsql, I applied to a mysql one, saved system settings and looks OK.
