[xwiki-devs] WYSIWYG editor loading time
by Marius Dumitru Florea 18 Oct '10

18 Oct '10

Hi devs, I noticed today that the time spent by Hudson to run all the WYSIWYG selenium tests (274) has increased from 19 to 22 minutes although the number of tests didn't change much from XE 2.4 and neither the tests' code. I wanted to know if this was caused by an increased WYSIWYG editor loading time so I did a quick profiling using Firefox 3.6.10 and Firebug 1.5.4. The WYSIWYG editor loading time (alone, excluding other artifacts on the host page) has three components: (T1) time to interpret the WYSIWYG editor JavaScript code (~530KB) (T2) time to load the edited document in the in-line frame (T3) time to load the editor plugins and to initialize the UI (menu, tool bar) It seems that (T3) is: * XE 2.4 -> 219.128ms, 26753 calls * XE 2.5 -> 242.968ms, 28282 calls Next I checked with Firebug's Net tab the page loading time. In order to test the editor alone I created a simple velocity template (wysiwyg.vm) that includes only the editor (plus the JavaScript and stylesheets needed by the editor). XE 2.4 ------ 4.35s -> WYSIWYG edit mode with SmartClient 2.47s -> WYSIWYG edit mode without SmartClient 3.4s -> xpage=wysiwyg with SmartClient 1.7s -> xpage=wysiwyg without SmartClient XE 2.5 ------ 3.9s -> WYSIWYG edit mode with SmartClient 2s -> WYSIWYG edit mode without SmartClient 3.2s -> xpage=wysiwyg with SmartClient 1.3s -> xpage=wysiwyg without SmartClient So the overall page loading time in edit mode has decreased. Also note that SmartClient adds a lot of time and it is used only for the XWiki Explorer tree.. This means the increased time spent on WYSIWYG selenium tests is caused by something else. Thanks, Marius

[xwiki-devs] [VOTE] Stop supporting the Albatross skin
by Sergiu Dumitriu 18 Oct '10

18 Oct '10

Hi devs, I'd like to propose that we don't maintain the Albatross skin anymore, since it's time consuming to port all the UI improvements and fixes to it. The skin will not be removed from the distribution yet, since it's still the base skin on which Toucan and Colibri are built, although we should try to fix this dependency in the near future. -- Sergiu Dumitriu http://purl.org/net/sergiu/

[xwiki-devs] Create a trunks for enterprise/ in SVN
by Vincent Massol 17 Oct '10

17 Oct '10

Hi devs, I'd like to create svn externals for enterprise in enterprise/trunks that would build both platform and enterprise. I would put a pom.xml in trunks for doing that. The need is to have a single maven multi module project to run Clover on (otherwise it's more complex for setting up Clover). WDYT? Thanks -Vincent

[xwiki-devs] Remove com.xpn.xwiki.test.smtp package
by Vincent Massol 16 Oct '10

16 Oct '10

Hi, I'd like to remove this package which doesn't seem to be used and is something used for testing and thus has nothing to do in src/main/java. In addition for tests we now use Greenmail. Please let me know if you think this is used somewhere and I've missed it. Thanks -Vincent

[xwiki-devs] [proposal] Add public void setContent(InputStream is) throws IOException to c.x.x.doc.XWikiAttachment.
by Caleb James DeLisle 15 Oct '10

15 Oct '10

This is just a small API change proposal. Since my implementation changes for XWikiAttachment store the attachment content in a temp file rather than a byte array, there is no need to require the user to provide the length of the provided stream and in many cases (upload for instance) this number is very difficult to determine in advance. I propose we add: public void setContent(InputStream is) throws IOException In addition to the existing: public void setContent(InputStream is, int length) throws IOException WDYT? Caleb

[xwiki-devs] [discussion] The future of attachments and attachment versioning.
by Caleb James DeLisle 14 Oct '10

14 Oct '10

Hi, I have some changes to the attachment system which will allow XWiki to handle much larger attachments without memory exhaustion. I have found that there are some places where I cannot make any changes because the code is not in XWiki but rather in JRCS. XWiki versions attachments by creating a JRCS node for the XML version of each version of each attachment. This means that memory consumption improvements hit a hard wall at 2 * 2 * 1.3 * the size of the attachment. base-64 encoding for XML increases the size by 1.3 times, storage as a String (array of 16 bit chars) doubles the size and the need to copy the String doubles the size again. The second issue is that the database and JDBC do not handle multiple hundreds of megabytes in a single query well. If I try to attach a 500MB attachment with attachment versioning disabled, my changes allow the attachment to be streamed to the database but postgresql is not able to save it. I am able to attach a 256MB attachment but with 512MB of heap space, the attachment cannot be loaded from the database because JDBC lacks the necessary streaming functionality. An option which I am now considering is adding a binary table to the database schema. The table would contain a composite id made of the id of the data and the part number of that entry, and a data column slightly smaller than 1MB (default max_allowed_packet in mysql). All interaction with this table would go through a storage engine which would require InputStreams and OutputStreams and the streams would be written and read by the storage mechanism which would ID tag them and break them up into parts to be sent to the database individually. WDYT? Caleb

[xwiki-devs] [VOTE] Better release strategy
by Sergiu Dumitriu 14 Oct '10

14 Oct '10

Hi devs, I don't think that Monday is a good day for releases, since voting over the weekend is not a good thing. Thus, I propose to move the general release day to the Thursday of the week. The current release process doesn't really follow the VOTE rules, since the way it's done is: send vote mail at 10AM, wait a few hours, start the release around 1PM. The rule for VOTE emails is to wait for three days. Thus: - Send release VOTE on Monday - Prepare the release during the following three days (release plan, release notes) - Perform the maven release on Thursday, request tests for publishing the release (testing of the build) - Finalize the release on Friday (download, announcements, version update) -- Sergiu Dumitriu http://purl.org/net/sergiu/
