LANG property in startup script in standalone version
by Vincent Massol 10 Jul '08

10 Jul '08

Hi, Does anyone know why we have the following LANG property defined in our startup scripts: #!/bin/sh export LANG=fr_FR.ISO8859-1 JETTY_HOME=. JETTY_PORT=8080 JAVA_OPTS=-Xmx300m java $JAVA_OPTS -Dfile.encoding=iso-8859-1 -Djetty.port=$JETTY_PORT - Djetty.home=$JETTY_HOME -jar $JETTY_HOME/start.jar I think this is bad as it's french and I don't think we should set it for the user. That said, if it's there its probably because it was required in the past, hence my question here. To summarize: anyone sees any issue if I remove that "export LANG" line? Thanks -Vincent

Attaching an image from another document?
by Vincent Massol 22 May '08

22 May '08

Hi, I'd like to attach an image to the current document but the image is attached to another document. I couldn't find the answer in the FAQ. It would be great if the {image:} radeox macro allowed for this. Right now the only solution I'v found (which is a bit ugly) is to use an HTML <img> tag as in: <img src="/xwiki/bin/download/XWiki/Toolbar/image.gif" /> Any other solution I would have missed?

[Proposal] Document history storage
by Sergiu Dumitriu 27 Jul '07

27 Jul '07

Hi, Sometime ago, there was a discussion regarding how should the document history be stored in a better way. Right now, the complete history is stored as one field in the xwikidoc table. From my PoV, this has some major disadvantages: - loading an older version requires parsing all the history -> memory inefficiency - as the documents grow older, loading a document will take a lot of time -> time inefficiency - queries on archives cannot return just one version, but they match the whole document (somewhere in the history, there was a version containing "search term") The blocking issue with storing old version in a different table was, at that time, the fact that a document archive should contain all information needed for completely restoring the document, like content, metadata, objects. I don't think that is actually an issue. We are archiving document versions, but we're joining all versions in one large string. Why don't we archive the complete version, but one version per row? So, the archive table should look like: - document name - version number - language (for translations) - content - archived metadata (one field, or the same fields as in xwikidoc) - archived objects (one field) - attachment names and versions It is not like storing the version as a normal document is, with separate objects and properties, but at least it provides a better storage and retrieval mechanism, and it separates a bit the parts of a wikidocument - content, metadata, objects.

XWikiMessageTool refactoring
by Sergiu Dumitriu 16 Jul '07

16 Jul '07

Hi, I looked today over the XWikiMessageTool class, and I must say that I'm not quite satisfied with it. First, there was XWIKI-919, which I implemented. OK, I understand that files stored on disk should be charset independent, so only ASCII characters are supported by the ResourceBundle class (jvm) .But, when I can edit a wiki document for storing bundles, I expect it to accept all the characters the wiki supports (in my case, it was an UTF8 instance). I had some troubles fixing this, since the JavaDoc says that bundles accepts only ASCII characters, but it understands and parses unicode references ( \u0123 ). Maybe I did something wrong, but doing content.replaceAll("\u0139", "\\u0139") resulted in the string u0139 being displayed in the page. So I had to trick it into believing that the component bytes of the encoding are ASCII characters and manually restore the multibyte chars. Second, I don't like the fact that XWIKI-921 was not already implemented. Third, I don't like the cache refresh mechanism. It retrieves the XWikiProperties->documentBundles property for each request, and It retrieves the bundle documents for every request and checks if it must be refreshed or not. Why isn't the com.xpn.xwiki.notify package used? It allows registering callback handlers for specific document changes. How I see it: - at startup, register a handler for XWiki.XWikiPreferences (so that we know when the documentBundles property might change). - remember the list of document bundles, don't ask it for each request - also register handlers for the current bundle documents and load the strings from these documents - when XWikiPreferences is changed, if the documentBundle property is also changed, remove the unused bundles and build the new ones - when a undle document (or a translation for it) is changed, rebuild the bundle for that document This should speedup the code a bit, it makes use of a nice, but mostly unknown feature, it doesn't log an error for each request when a specified document is not found in the wiki, and it doesn't require so many variables (previousDates, docsToRefresh). Fourth, as I said above, if a document is specified in the documentBundles property, but it does not exist in the wiki, for each $msg.get call an error is logged. And there are a lot of calls for each request. Now, in my opinion this is a nice way to get in the core of XWiki for a newcomer, so does anybody want to write the changes I mentioned? Also, this is a good occasion to document the event notification mechanism, in JavaDoc and on www.xwiki.org Regards, Sergiu Dumitriu -- http://purl.org/net/sergiu

[Proposal] Some/All fields in the database should be longer
by Sergiu Dumitriu 08 Jul '07

08 Jul '07

There are many properties stored in VARCHAR(255) fields, which sometimes isn't enough. This already causes http://jira.xwiki.org/jira/browse/XWIKI-883 . Changing to variable length field doesn't have any major side effects, as I know. As pro arguments: 1. The size of the database will not increase 2. There are already some fields stored as mediumtext and longblob, so it's not something new in the database 3. The fewer limits there are, the better 4. Issues like XWIKI-883 will be fixed ... and maybe more Is there something I'm missing that prevents this? -- http://purl.org/net/sergiu

Hello. I have a strange bug then building xwiki-enterprise-database by maven2 indirectly (by pom <modules>): $ cd xwiki-product-enterprise $ mvn clean; mvn install result: database files in xwiki-product-enterprise/target/database but not in xwiki-product-enterprise/database/target/database so xwiki-enterprise-database-1.1-SNAPSHOT-hsqldb.zip is empty (if I directly building database (`cd xwiki-product-enterprise/database; mvn install;`) - all is fine) environment: maven-2.1-SNAPSHOT(29 june) sun-jdk-1.6 xwiki trank (29 june), unchanged gentoo linux all configs looks normally I looked all configs, looked at mvn -X and found nothing strange. I created simple m2 project like xwiki-product-enterprise but with only the database as m2 module - the same error. Why it can be? -- Artem Melentyev

$msg.get
by evelyne24＠gmail.com 04 Jul '07

04 Jul '07

Hello all, What is $msg variable, and where can I read more about it? (is not in xwikivars.vm...) And how does $msg.get() works? Please, I really need some help. I want to include support for languages in my datepicker and Sergiu told me to put the strings in ApplicationRessources.properties and now I'm trying to get them in a js file with $msg.get("core.datepicker.somethingdefinedbymehere"), but it seems that the server does not know how $msg is, but it knows who $xwiki, $context and all other are.... So please, please, I would like to know more about this variable or how to get the strings from ApplicatonRessources. I'd really appreciate some help because I'm stuck on this.... Thank you very much, Evelina

Hi Stephane, Maybe a quick word of what this is so that others know? Maybe a README dropped in there would be good too.

Hi All I am new to XWiki and want to set it up on my local workstation (using MySQL as the DB) , then modify the code and re-build it. I have the copy of the code taken from the following SVN URL:(**svn://svn.forge.objectweb.org/svnroot/xwiki/xwiki/trunk**) .Please suggest the methods for the following: 1. Ant targets for building XWiki (in all the modes) 2. deploy targets for XWiki 3. Changes in the code for MySQL other than the db properties in the hibernate config (if any). 4. any other suggestions/precautions Thanks Gaurav

[SVN] Create new externals and move current trunks-devs/users
by Vincent Massol 29 Jun '07

29 Jun '07

Hi, I think we need an easy way for everyone to build only the product he's working on. Thus I'd like to propose the creation of a new svn:externals for the platform only and to move externals in a specific dir: /svnroot/xwiki |_ externals/ |_ trunks-devs/ |_ trunks-users/ |_ trunks-platform-devs/ |_ trunks-platform-users/ This will achieve the following use cases: Use case 1: I'm working on product XX and I'm not making any change to the platform - checkout just the product's trunk. For example /svnroot/xwiki/xwiki- products/xwiki-watch/trunk Use case 2: I'm working on both the platform and XWiki Enterprise but not the other products - checkout /svnroot/xwiki/externals/trunks-platform-devs/ - checkout XWiki Enterprise: /svnroot/xwiki/xwiki-products/xwiki- enterprise/trunk Caveat: you can't build both at the same time but you can build each one with a single command. Use case 3: I'm working on everything - checkout /svnroot/xwiki/externals/trunks-devs/ Another option would be to create one externals per product but it's a little bit of a pain to maintain. It's possible though. Actually this would allow to fine tune the build to that only platform components required for the product are built. For example, only the plugin used by the product and only the applications built by the product would be built. Actually this probably makes sense. In that case we would have: /svnroot/xwiki |_ externals/ |_ trunks-devs/ |_ trunks-users/ |_ trunks-platform-devs/ |_ trunks-platform-users/ |_ trunks-enterprise-devs/ |_ trunks-enterprise-users/ |_ trunks-enterprise-manager-devs/ |_ trunks-enterprise-manager-users/ |_ trunks-watch-devs/ |_ trunks-watch-users/ |_ trunks-curriki-devs/ |_ trunks-curriki-users/ A last option would be to put the full platform under the same trunk/ but I don't think this is right as we should be able to release platform modules separately. WDYT? Thanks -Vincent
