r11048: r10539@SERNOX: metze | 2005-09-27 14:59:47 +0200

 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
