[Fedora-directory-devel] Please review: [Bug 171081] ldapsearch hung at browsing index creation

[Noriko Hosoi]

Summary: ldapsearch hung at browsing index creation

https://bugzilla.redhat.com/show_bug.cgi?id=171081


This bug was introduced while fixing another bug: deleting a vlv index while it's being created makes the server crash.

cvs diff ldif2ldbm.c vlv.c

Files: ldapserver/ldap/servers/slapd/back-ldbm/ldif2ldbm.c
					       vlv.c

Fix Description:
1. instead of covering all the reindexing loop, set vlv lock just around
vlv_update_index, where vlv update is executed.
2. actually, lock is not meant to use for excluding the operation against vlv
reconfiguration.  This ldbm_back_ldbm2index function first calls
instance_set_busy_and_readonly and protects the backend from the operations done
by other threads.  vlv delete call was just ignoring the busy/readonly setting. 
Thus, changed the vlv code to respect the setting.  Found the backend is busy,
deleting a vlv index fails and returns.
3. cleaned up the instance_set_busy_and_readonly function not to leak memory.
4. fixed minor memory leak.


Thanks,
