Hi,
As explained in [1] an exception is thrown when accessing the pubisher and
store apps.
When these are accessed for the first time, an SQL resource is added to the
location
"/repository/components/org.wso2.carbon.registry/queries/tag-summary" of
the config space.
Within the publisher app, following code is used to obtain the related
registry space;
Registry configRegistry =
ServiceReferenceHolder.getInstance().getRegistryService().getConfigSystemRegistry();
As observed following takes place in the registry side, after calling the
configRegistry.put method;
1. Since the inserted resource is marked as an SQL media type, at a
pointSQLQueryHandler.putis called.
2.The location of the resource is identified as a non existing one,
therefore it gets created level by level.
3.The new location gets created by addEmptyCollection method in
Repositoryclass, which is recursively called until an existing
parentResourceID is
found.
4. Once it reaches an existing parentResourceID (in this case it is
/_system/local/repository/), the immediate child collection (components) is
created in the underlying database by resourceDAO.add method.
5. This subsequently calls to createAndApplyResourceID in JDBCResourceDAO,
which ultimately calls to createResourceID.
6. The problem originates when executing the block;
JDBCDatabaseTransaction.ManagedRegistryConnection conn =
JDBCDatabaseTransaction.getConnection();
JDBCPathCache pathCache = JDBCPathCache.getPathCache();
int pathID = pathCache.getPathID(conn, path);
if (pathID == -1) {
pathID = pathCache.addEntry(path, parentPathID);
}
"conn" variable points to the database where local space is stored, meaning
that the pathID is first fetched from the local_space (which is the
expected behaviour).
The call to pathCache.addEntry, subsequently invokes
dataAccessManager =
CurrentSession.getUserRegistry().getRegistryContext().getDataAccessManager();
to get a datasource (the new collection 'components' gets actually stored
here). But this datasource actually points to the database where config
space is mounted.
The problem in short is path is retrieved from one location, but it is
stored to another.
Has this to do anything with the way the registry space is obtained?
