The decision which Promise implementation to use should be made by
LoopBack user, not by the framework.
This commit moves Bluebird reference from lib/utils.js to
test/support.js.
Modify `app.enableAuth` to automaticaly setup all required models
that are not attached to the app nor a datasource.
Users wishing to use this option must provide the name of the
data-source to use for these models.
Example usage:
var app = loopback();
app.dataSource('db', { connector: 'memory' });
app.enableAuth({ dataSource: 'db' });
app.use(loopback.rest());
app.listen(3000);
When creating an application with a local registry, the default
behaviour is to define only two core models Model & PersistedModel.
The new flag `loadBuiltinModels` modifies this behaviour and instructs
loopback to define all builtin models in the local registry too.
Process `settings.methods` and `config.methods` as a key-value map
where the key is the method name and the value is an object describing
the method in the format expected by strong-remoting.
Example: a static method `Model.create`
"methods": {
"create": {
"isStatic": true,
"accepts": {
"arg": "data", "type": "Car",
"http": { "source": "body" }
},
"returns": { "arg": "data", "type": "Car", "root": true }
}
}
This patch is based on the code proposed by @mrfelton in #1163.
This patch fixes the method Model.getApp() that started to report
the following error after b61fae5 was landed:
assert.js:88
throw new assert.AssertionError({

Fix a regression introduced by b917075 where two loopback projects,
each one using a different instance of loopback module, were
sharing the global registry and thus not working correctly.
The issue was discovered by unit-tests in loopback-workspace.
The commit b917075 accidentally removed a couple of properties,
this commit is bringing them back:
- loopback.modelRegistry
- loopback.defaultDataSources
A unit-test was added to prevent this kind of regressions in the future.
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).
Correctly handle the case when the model is attached multiple times
during the lifecycle, this happens because `loopback.createModel`
always makes an attempt to auto-attach.
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`.
Modify the files to export a model factory function accepting
a `registry` argument. This is a preparation step for per-application
models - see #1212.
Deprecate `Change.handleError`, it was used inconsistenly for a subset
of possible errors only. Rework all `Change` methods to always report
all errors to the caller via the callback.
Rework `PersistedModel` to report change-tracking errors via the
existing method `PersistedModel.handleChangeError`. This method
can be customized on a per-model basis to provide different error
handling.
The default implementation emits `error` event on the model class,
users can attach an event listener that can provide a custom error
handler.
NOTE: Unhandled `error` events crash the application by default.
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
Use the recently added context property `ctx.instance` to improve
the accuracy of the algorithm detecting whether a single or
multiple models were deleted.
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.)
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.
