* s3:dbwrap_ctdb: fix fetch/fetch_locked when samba is built against old ctdbMichael Adam2012-06-291-4/+3
| | | | | | | | | | | | The introduction of read only copies has broken the algorithm for deteting whether we can use the local record copy for fetch_locked and fetch: For fetch locked the new code always uses the local copy if there is one... This patch re-establish the original algorithm for the build against a ctdb without read only record copies. Reported-by: Gregor Beck <gbeck@sernet.de>
* s3-param: Rename loadparm_s3_context -> loadparm_s3_helpersAndrew Bartlett2012-06-272-2/+2
| | | | | | | | | | | | | | | | | This helps clarify the role of this structure and wrapper function. The purpose here is to provide helper functions to the lib/param loadparm_context that point back at the s3 lp_ functions. This allows a struct loadparm_context to be passed to any point in the code, and always refer to the correct loadparm system. If this has not been set, the variables loaded in the lib/param code will be returned. As requested by Michael Adam.

It's easier to remove it than to translate the NTDB flags to TDB flags, and it's a really weird thing to ask for anyway. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
