fix the build for changes from SAMBA_4_0 branch metze r10541@SERNOX: metze | 2005-09-27 15:05:33 +0200 use a transaction when we allocate a new version metze r10549@SERNOX: metze | 2005-09-27 18:58:37 +0200 - add first start of wins pull replication - we not yet apply records to our database but we fetch them correct form our partners (we need conflict handling for this) - we also need to filter out our own records! metze r10568@SERNOX: metze | 2005-09-28 11:33:04 +0200 move composite helpers to a seperate file, create a a seperate file for the conflict resolving logic metze r10571@SERNOX: metze | 2005-09-28 12:00:17 +0200 add forward declarations...to fix the build metze r10612@SERNOX: metze | 2005-09-29 16:11:06 +0200 we have a nbt_name now, and don't need to parse it metze r10614@SERNOX: metze | 2005-09-29 16:38:35 +0200 filter out our own records metze r10620@SERNOX: metze | 2005-09-29 18:07:08 +0200 - handle mutliple addresses in WREPL_REPL_SEND_REPLY - make strings always valid talloc pointers metze r10621@SERNOX: metze | 2005-09-29 18:09:41 +0200 use debug level 2 metze r10622@SERNOX: metze | 2005-09-29 18:48:05 +0200 - add one more debug message when we reply no record - fix min max logic metze r10623@SERNOX: metze | 2005-09-29 20:49:06 +0200 build fixes... metze r10629@SERNOX: metze | 2005-09-30 00:11:41 +0200 - use seperate attributes for type, state, nodetype, is_static ... the winserver.c code needs some more updates to correctly, create special group and multihomed registrations... metze r10640@SERNOX: metze | 2005-09-30 04:07:34 +0200 - add some short path for the composite helper functions they will be used in the next commit metze r10642@SERNOX: metze | 2005-09-30 06:29:06 +0200 fix the build metze r10655@SERNOX: metze | 2005-09-30 17:36:49 +0200 - implement the WREPL_REPL_UPDATE* and WREPL_REPL_INFORM* this includes the connection fliping into a client connection for WREPL_REPL_UPDATE* NOTE: I not yet found out how to get the w2k server to use INFORM against samba4 it uses inform against w2k and w2k3 but UPDATE against nt4 and samba4 what's left now is to be able to initiate INFORM and UPDATE requests to notify our pull partners metze r10727@SERNOX: metze | 2005-10-05 14:11:05 +0200 fix the build metze r10770@SERNOX: metze | 2005-10-06 16:56:01 +0200 - move the table filling to a seperate function, will be reused later - fix the build, wrepl_nbt_name fixes - remove state -> update_state metze r10771@SERNOX: metze | 2005-10-06 17:04:48 +0200 add a function to create a wreplsrv_in_connection from a client connection metze r10772@SERNOX: metze | 2005-10-06 17:13:51 +0200 - make the connection code more generic to handle the pull cached connection, push cached connection or given connections - when we don't use a cached connection, disconnection when a pull_cycle is done - fix the build and use the configured source ip metze r10773@SERNOX: metze | 2005-10-06 17:18:49 +0200 - add composite functions for push notification metze r10774@SERNOX: metze | 2005-10-06 17:23:46 +0200 - use periodic push notifycation, this is just for now as it needs to be configurable and and be triggered when the local database has changes since the last notify - I also need to work out how to decide if the partner supports persistent connections and WREPL_REPL_INFORM* messages metze r10923@SERNOX: metze | 2005-10-12 16:52:34 +0200 fix the build becuse of conflicts with main SAMBA_4_0 tree metze (This used to be commit 6d97dd6e50423758d081459ec551f4e04dfd818d)
