* dsdb: Do not refresh the schema using the wrong event contextAndrew Bartlett2014-06-111-2/+0
| | | | | | | | | | | | | | | | What we now do is have the refresh function and module be on a seperate object to the schema, only referring to the data and not excuting on the original ldb and event loop. That is, we never use another ldb context when calling the refresh function, by binding the refresh handler to the ldb and not the schema.

* dsdb: Do not store a struct ldb_dn in struct schema_dataAndrew Bartlett2014-06-111-8/+0
| | | | | | | | | | | | The issue is that the DN contains a pointer to the ldb it belongs to, and if this is not kept around long enough, we might reference memory after it is de-allocated.

* dsdb-schema: make deduplication of class and schema possible (bug #8680)Matthieu Patou2013-05-231-5/+67
| | | | | | | | | | | | | | When a class or an attribute is replicated it might already exists in the existing schema, so while replicating the new version of this object we want to get rid of the old version of the object is the current validating schema so that we don't end up having duplicates.

* s4-dsdb: Do not use a possibly-old loadparm context in schema reloadAndrew Bartlett2012-08-231-12/+14
| | | | | | | | The loadparm context on the schema DB might have gone away already. Pre-cache the schema refresh interval at load time to avoid worrying about this. Andrew Bartlett
* s4-dsdb: Add mem_ctx argument to samdb_ntds_settings_dnAndrew Bartlett2012-08-141-1/+1
| | | | | | | | | | | | | | As this value is calculated new each time, we need to give it a context to live on. If the value is the forced value during provision, a reference is taken. This was responsible for the memory leak in the replication process. In the example I was given, this DN appeared in memory 13596 times!

* s4-dsdb_schema: Copy info needed for Schema refresh in dsdb_schema_copy_shallowKamen Mazdrashki2010-12-181-0/+4
| | | | | | | | Just 'refresh_fn' and 'loaded_from_module' are copied. I left 'reload_seq_number' set to 0 intentionally, so that this Schema cache will looks like a very old one to ,refresh_fn'. This way, if this shallow copy is attached to LDB, it will be refreshed as soon as possible by 'refresh_fn'.

* s4-dsdb: use ldb_operr() in the dsdb codeAndrew Tridgell2010-07-071-5/+4
| | | | | | | this replaces "return LDB_ERR_OPERATIONS_ERROR" with "return ldb_operr(ldb)" in places in the dsdb code where we don't already explicitly set an error string. This should make is much easier to track down dsdb module bugs that result in an operations error.
* s4:dsdb Fix possible schema segfaults for DRS-replication based schemaAndrew Bartlett2010-06-301-17/+13
| | | | | | | | | The problem here is that if the schema has been modified on the source domain, there may be attributes that appear over DRS with 0 values (to indicate that any existing values on the target should be deleted). This would confuse the previous version of this macro. Andrew Bartlett
* s4:dsdb Use the schema from our local provision to decode the schemaAndrew Bartlett2010-06-151-367/+0
| | | | | | | | | | | | | | This works on the assumption that the schema partition can only contain schema objects. We may need to pass down some kind of 'relax' to the DRS -> LDB conversion code, so that it allows incomplete conversions, so that we don't fail if a new attribute is present, and we can't decode it. This would then be resolved the second time we do the conversion. Andrew Bartlett Signed-off-by: Kamen Mazdrashki <kamenim@samba.org>

* s4:dsdb Load objectGUID and extended DN defaultObjectCategory into the schemaAndrew Bartlett2009-11-171-35/+25
| | | | | | | | | | | | | | The load of defaultObjectCategory as an extended DN means we need to use the common parsing functions I just split out, rather than the GET_DS_DN macro. The objectGUIDs are loaded so that we can create the extended DN when we load from LDIF (and are loaded for the other cases for consistency). Also adapt callers to API changes needed for common parsing code Andrew Bartlett
