Modify `Change.diff()` to include current data revision in each
delta reported back. The current data revision is stored in
`delta.prev`.
Modify `PersistedModel.bulkUpdate()` to check that the current data
revision matches `delta.prev` and report a conflict if a third party
has modified the database under our hands.
Fix `Change` implementation and tests so that they are no longer
attempting to create instances with duplicate ids.
(This used to work because the memory connector was silently
converting such requests to updateOrCreate/findOrCreate.)
This commit adds the ability for the developer to use a custom token generator function for the user.verify(...) method. By default, the system will still use the crypto.randomBytes() method if no option is provided.
Add tests covering typical replication scenarios that happen
in the setup where multiple clients are synchronizing changes
against a single server (database).
Rework the Change model to merge changes made within the same
Checkpoint.
Rework `replicate()` to run multiple iteration until there were no
changes replicated. This ensures that the target model is left in
a clean state with no pending changes associated with the latest
(current) checkpoint.

* Config option to disable legacy explorer routes Setting legacyExplorer to false in the loopback config will disable the routes /routes and /models made available in loopback.rest. The deprecate module has been added to the project with a reference added for the legacyExplorer option as it is no longer required by loopback-explorer. Tests added to validate functionality of disabled and enabled legacy explorer routes. (Ron Edgecomb)

Extend `PersistedModel.replicate` to pass the newly created checkpoints
as the third callback argument.
The typical usage of these values is to pass them as the `since`
argument of the next `replicate()` call.
global.since = -1;
function sync(cb) {
LocalModel.replicate(
since,
RemoteModel,
function(err, conflicts, cps)
if (err) return cb(err);
if (!conflicts.length) {
since = cps;
return cb();
}
// resolve conflicts and try again
});
}
Before this change, in the case of a one-way replication, the remote
checkpoint was never updated, thus the "diff" step had to check
all changes made through the whole history.
This commit fixes the problem by creating a new remote checkpoint
at the same time when a local checkpoint is created.
It is important to create the new checkpoint before the replication is
started to prevent a race condition where a remote change can end up
being associated with an already replicated checkpoint.
Rework the "replicate()" to create a new source checkpoint as the first
step, so that any changes made in parallel will be associated with
the next checkpoint.
Before this commit, there was a race condition where a change might
end up being associated with the already-replicated checkpoint and thus
not picked up by the next replication run.
Modify `PersistedModel.replicate` to allow consumers to provide
different "since" values to be used for the local and remote changes.
Make the "since" filters consistent and include the "since" value
in the range via `gte`. Before this commit, the local query used
`gt` and the remote query used `gte`.
Setting legacyExplorer to false in the loopback config will disable
the routes /routes and /models made available in loopback.rest.
The deprecate module has been added to the project with a reference
added for the legacyExplorer option as it is no longer required by
loopback-explorer. Tests added to validate functionality of disabled
and enabled legacy explorer routes.
Fix all test models that are tracking changes so that they have
a generated unique string id.
Make model names unique where possible to prevent tests reusing
the same model which causes unintented side effects.
