| Description: |
It seem that sometime when we call the livedata rest API we don't have a consistent result when we do some call currently concurrently .
We can see the consequence by , for example on this issue: https://jira.xwiki.org/browse/BVERSION-106
It's not an easy bug to reproduce manually, I was able to reproduce it but it happen randomly, not in all case.
So to have a better way to reproduce this issue I made this following bash script:
{code:java}
for ((i=0; i<10; i++)); do
(
versionClassNb=$(curl -s -u Admin:admin 'http://localhost:8080/xwiki/rest/liveData/sources/liveTable/entries?sourceParams.className=XWiki.XWikiUsers' -H 'Accept: application/json, text/javascript, */*; q=0.01' | jq .count)
sleep 0.2
echo "Number of users: $versionClassNb"
) &
proc1Nb=$!
(
pageStatusClassNb=$(curl -s -u Admin:admin 'http://localhost:8080/xwiki/rest/liveData/sources/liveTable/entries?sourceParams.className=XWiki.XWikiRights' -H 'Accept: application/json, text/javascript, */*; q=0.01' | jq .count)
sleep 0.3
echo "Number of rights $pageStatusClassNb"
) &
proc2Nb=$!
wait $proc1Nb
wait $proc2Nb
done
{code}
When I run this script on a clean xwiki instance on 16.10.1 I've this result:
{code:java}
Number of users: 1
Number of rights 1
Number of users: 3
Number of rights 3
Number of users: 1
Number of rights 1
Number of users: 1
Number of rights 1
Number of users: 3
Number of rights 3
Number of users: 3
Number of rights 3
Number of users: 3
Number of rights 3
Number of users: 1
Number of rights 1
Number of users: 1
Number of rights 3
Number of users: 1
Number of rights 1
{code}
Normally we expect that we have always:
{code:java}
Number of users: 1
Number of rights 3
{code} |
