The database is then in state ** (S1+"remote"), where the exact state depends on any conflict ** resolution decisions (OMIT or REPLACE) made while applying "remote". ** Rebasing a changeset is to update it to take those conflict ** resolution decisions into account, so that the same conflicts ** do not have to be resolved elsewhere in the network. ** ** For example, if both the local and remote changesets contain an ** INSERT of the same key on "CREATE TABLE t1(a PRIMARY KEY, b)": ** ** local: INSERT INTO t1 VALUES(1, 'v1'); ** remote: INSERT INTO t1 VALUES(1, 'v2'); ** ** and the conflict resolution is REPLACE, then the INSERT change is ** removed from the local changeset (it was overridden). Or, if the ** conflict resolution was "OMIT", then the local changeset is modified ** to instead contain: ** ** UPDATE t1 SET b = 'v2' WHERE a=1; ** ** Changes within the local changeset are rebased as follows: ** ** <dl> ** <dt>Local INSERT<dd> ** This may only conflict with a remote INSERT.

If it conflicts ** with a DELETE, and the conflict resolution was OMIT, then the update ** is changed into an INSERT. Any undefined values in the new.* record ** from the update change are filled in using the old.* values from ** the conflicting DELETE.

And that ** modifications are made that move that database to state S1 and a ** changeset recorded (the "local" changeset). Then, a changeset based ** on S0 is received from another site (the "remote" changeset) and ** applied to the database. The database is then in state ** (S1+"remote"), where the exact state depends on any conflict ** resolution decisions (OMIT or REPLACE) made while applying "remote". ** Rebasing a changeset is to update it to take those conflict ** resolution decisions into account, so that the same conflicts ** do not have to be resolved elsewhere in the network. ** ** For example, if both the local and remote changesets contain an ** INSERT of the same key on "CREATE TABLE t1(a PRIMARY KEY, b)": ** ** local: INSERT INTO t1 VALUES(1, 'v1'); ** remote: INSERT INTO t1 VALUES(1, 'v2'); ** ** and the conflict resolution is REPLACE, then the INSERT change is ** removed from the local changeset (it was overridden). Or, if the ** conflict resolution was "OMIT", then the local changeset is modified ** to instead contain: ** ** UPDATE t1 SET b = 'v2' WHERE a=1; ** ** Changes within the local changeset are rebased as follows: ** ** <dl> ** <dt>Local INSERT<dd> ** This may only conflict with a remote INSERT. If the conflict ** resolution was OMIT, then add an UPDATE change to the rebased ** changeset. Or, if the conflict resolution was REPLACE, add ** nothing to the rebased changeset. ** ** <dt>Local DELETE<dd> ** This may conflict with a remote UPDATE or DELETE. In both cases the ** only possible resolution is OMIT. If the remote operation was a ** DELETE, then add no change to the rebased changeset. If the remote ** operation was an UPDATE, then the old.* fields of change are updated ** to reflect the new.* values in the UPDATE. ** ** <dt>Local UPDATE<dd> ** This may conflict with a remote UPDATE or DELETE. If it conflicts ** with a DELETE, and the conflict resolution was OMIT, then the update ** is changed into an INSERT. Any undefined values in the new.* record ** from the update change are filled in using the old.* values from ** the conflicting DELETE. Or, if the conflict resolution was REPLACE, ** the UPDATE change is simply omitted from the rebased changeset. ** ** If conflict is with a remote UPDATE and the resolution is OMIT, then ** the old.* values are rebased using the new.* values in the remote ** change. Or, if the resolution is REPLACE, then the change is copied ** into the rebased changeset with updates to columns also updated by ** the conflicting remote UPDATE removed. If this means no columns would ** be updated, the change is omitted. ** </dl> ** ** A local change may be rebased against multiple remote changes ** simultaneously. If a single key is modified by multiple remote ** changesets, they are combined as follows before the local changeset ** is rebased: ** ** <ul> ** <li> If there has been one or more REPLACE resolutions on a ** key, it is rebased according to a REPLACE. ** ** <li> If there have been no REPLACE resolutions on a key, then ** the local changeset is rebased according to the most recent ** of the OMIT resolutions. ** </ul> ** ** Note that conflict resolutions from multiple remote changesets are ** combined on a per-field basis, not per-row. This means that in the ** case of multiple remote UPDATE operations, some fields of a single ** local change may be rebased for REPLACE while others are rebased for ** OMIT. ** ** In order to rebase a local changeset, the remote changeset must first ** be applied to the local database using sqlite3changeset_apply_v2() and ** the buffer of rebase information captured.
