Add end-to-end unit-tests verifying enforcement of access control during
conflict resolution.
Implement two facade methods providing REST API for Change methods used
by conflict resolution:
PersistedModel.findLastChange
GET /api/{model.pluralName}/{id}/changes/last
PersistedModel.updateLastChange
PUT /api/{model.pluralName}/{id}/changes/last
By providing these two methods on PersistedModel, replication users
don't have to expose the Change model via the REST API. What's even
more important, these two methods use the same set of ACL rules
as other (regular) PersistedModel methods.
Rework `Conflict.prototype.changes()` and `Conflict.prototype.resolve()`
to use these new facade methods.
Implement a new method `Conflict.prototype.swapParties()` that provides
better API for the situation when a conflict detected in Remote->Local
replication should be resolved locally (i.e. in the replication target).
1) Add integration tests running change replication over REST to verify
that access control at model level is correctly enforced.
2) Implement a new access type "REPLICATE" that allows principals
to create new checkpoints, even though they don't have full WRITE
access to the model. Together with the "READ" permission, these
two types allow principals to replicate (pull) changes from the server.
Note that anybody having "WRITE" access type is automatically
granted "REPLICATE" type too.
3) Add a new model option "enableRemoteReplication" that exposes
replication methods via strong remoting, but does not configure
change rectification. This option should be used the clients
when setting up Remote models attached to the server via the remoting
connector.
- `loopback.registry` is now a true global registry
- `app.registry` is unique per app object
- `Model.registry` is set when a Model is created using any registry method
- `loopback.localRegistry` and `loopback({localRegistry: true})` when set to `true` this will create a `Registry` per `Application`. It defaults to `false`.
Refactor the core implementation of current context from
server/middleware/context.js into server/current-context.js.
Expose new public API:
- loopback.runInContext
- loopback.createContext
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.
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
});
}
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.
Make the "redirect" parameter optional. When the parameter is not
specified, the server responds with an empty response (204). This allows
API clients to call the method without the need to handle redirects
and HTML responses.
Even when the "redirect" parameter is included, the builtin afterRemote
hook still calls next(), so that user-provided afterRemote hooks
are executed too.
Add unit-tests to verify that all DAO methods correctly create change
records.
Rework the change detection to use the new operation hooks, this fixes
the bugs where operations like "updateOrCreate" did not update change
records.
The patch strongloop/loopback-datasource-juggler#436 changed the way
how `Model.extend` works, which broke one loopback test relying on the
old behaviour.
This commit fixes the failing test. The test is checking now that
the model base was not changed, instead of checking that the base
is undefined.
Enhance the error objects with a `code` property containing
a machine-readable string code describing the error, for example
INVALID_TOKEN or USER_NOT_FOUND.
Also improve 404 error messages to include the model name.
