Description
See http://hole.tuziwo.info/stress-test-xwiki-for-subwikis-creation.html which led me to create this JIRA issue.
To reproduce:
- Download the XE standalone distribution (using HSQLDB)
- Create a page named WikiStressTestCode.FromRequest with the following content:
{{velocity}}
#set($wikiName = $!request.getParameter('wikiname'))
#set($wikiNumber = $!request.getParameter('wikinumber'))
#set($wikiId = "$!wikiName$!wikiNumber")
#if($wikiId.isEmpty())
#set($wikiName = 'Null')
#set($wikiNumber = 0)
#set($wikiId = 'null')
#end
#if($services.wiki.exists($wikiId))
#set($wiki = $services.wiki.getById($wikiId))
#else
#set($wiki = $services.wiki.createWiki($wikiId, $wikiId, 'xwiki:XWiki.Admin', true))
#end
#if($wiki)
#set($wikiPrettyName = "Wiki $wikiName #$wikiNumber ")
#set($discard = $wiki.setPrettyName($wikiPrettyName))
#set($wikiDescription = "Wiki $wikiName #$wikiNumber created for the stress test")
#set($discard = $wiki.setDescription($wikiDescription))
#set($discard = $services.wiki.saveDescriptor($wiki))
#else
#set($discard = $response.sendError(404, 'Error in creating the wiki'))
#end
{{/velocity}}
- Create another page (which can be used to remove all created wikis to try again) named WikiStressTestCode.DeleteWikis:
{{velocity}}
#foreach ($i in [1..300])
#set($discard = $services.wiki.deleteWiki("test${i}"))
#end
{{/velocity}}
- Create on the filesystem a file named create-wiki.sh in the directory where you start XWiki:
#!/bin/bash NUMBER=1 NAME=wiki if [ $# -ge 1 ] then NUMBER=$1 fi if [ $# -ge 2 ] then NAME=$2 fi curl \ --silent \ --show-error \ --user Admin:admin \ -F "wikiname="$NAME \ -F "wikinumber="$NUMBER \ -o data/$NAME.html \ http://localhost:8080/xwiki/bin/view/WikiStressTestCode/FromRequest
- Create a file named stress-test.sh next to it:
#!/bin/bash TEST_NUMBER=300 NAME=test LOG_FILE=stress-test-request.log if [ -f $LOG_FILE ] then rm $LOG_FILE fi if [ $# -ge 1 ] then TEST_NUMBER=$1 fi for num in `seq 1 $TEST_NUMBER` do echo "Creating wiki "$Name" #$num..." ./create-wiki.sh $num $NAME done
- Start XE
- Run stress-test.sh
- After some point you'll start to see permission errors. It can happen after 15 wikis have been created, after 80 or after 150. For me it happens regularly at around 50-60 wikis.
