2012-06-29s3:dbwrap_ctdb: fix fetch/fetch_locked when samba is built against old ctdbMichael Adam1-4/+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>
2012-06-27s3-param: Rename loadparm_s3_context -> loadparm_s3_helpersAndrew Bartlett2-2/+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.

2012-06-22dbwrap: remove get_flags().Rusty Russell1-8/+0
The flags returned were TDB-specific: this was only used for detecting the endianness of obsolete databases (the conversion code was put in in 2003, with reference to Samba 2.3). 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>
