XML parsing error after deleting a version from the history
-----------------------------------------------------------
Key: XWIKI-1948
URL: http://jira.xwiki.org/jira/browse/XWIKI-1948
Project: XWiki Platform
Issue Type: Bug
Components: Storage
Affects Versions: 1.2 RC1
Reporter: Sergiu Dumitriu
Fix For: 1.2 RC2
Scenario:
- Create a document with several versions in an 1.1 wiki
- Update to 1.2
- Delete a revision from the middle of the history
Trying to view older versions will throw an XML exception, while newer versions
are displayed successfully.
This is caused by the fact that during the upgrade the old rcs is preserved,
meaning that the history is stored as a diff on the old XML export. When
deleting the intermediary version, the new diff is computed not on the original
XMLs, but on the re-exported XMLs of the documents, which are different because
of the new <isMinorEdit> line. So, while the old rcs diff show a change at line
23, the new rcs diff shows a change at line 24, which is applied on an XML
where the changed line should actually be 23.
