Clustering: race condition may cause duplicate entries in search index
----------------------------------------------------------------------
Key: JCR-905
URL: https://issues.apache.org/jira/browse/JCR-905
Project: Jackrabbit
Issue Type: Bug
Components: core
Affects Versions: 1.3
Reporter: Martijn Hendriks
There seems to be a race condition that may cause duplicate search index
entries. It is reproducible as follows (Jackrabbit 1.3):
1) Start clusternode 1 that just adds a single node of node type
clustering:test.
2) Shutdown clusternode 1.
3) Start clusternode 2 with an empty search index.
4) Execute the query //element(*, clustering:test).
4) Print the result of the query (UUIDs of nodes in the result set).
When I just run clusternode 2, then there is one node in the resultset, as
expected. However, when I debug clusternode 2 and have a breakpoint (i.e., a
pause of a few seconds at line 306 of RepositoryImpl.java - just before the
clusternode is started), then the resultset contains two results, both with the
same UUID.
