Use local registry in test fixtures to prevent collision in globally
shared models.
Fix issues discoverd in auth implementation where the global registry
was used instead of the correct local one.
*Re-mapping `updateAttributes` endpoint to use
`PATCH` and `PUT`(configurable) verb
*Exposing `replaceById` and `replaceOrCreate` via
`POST` and `PUT`(configurable) verb
Modify `Change.rectify` to look up the current checkpoint only when
there was actually some change made.
This should improve the performance of `rectifyAll` when called from a
regular timer and there were no changes made since the last call.
Before this commit, `rectifyAll` would perform N calls of
`Checkpoint.current` where N is the number of model instances. With
this commit in place, no call is made.
Modify `Change.rectify()` to not make any changes to the Change instance
(most notably to not modify the `checkpoint` field) when the tracked
model instance was not changed.
This should improve the performance of change replication as it reduces
the number of unnecessary replications.
For example, before this commit, every run of `rectifyAll` would
trigger a full sync of all clients, because all change instances would
be moved to the current checkpoint.
Fix `Application.resetKeys()` to reset instance id only if it is not
already set. This fixes a bug where each call of resetKeys created
a new instance.
Change the type of the "include" argument to "string array".
The type used to be "string" before and thus requests sending multiple
include items were technically incorrect.
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`.
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.
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.
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
});
}
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.
Express has recently deprecated `req.param()` to force developers
to be explicit about the source of the value. To avoid deprecation
warnings, this commit replaces all calls of `req.param()` with a
simplified inline version.
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.
Allow convenient URLs for curl and browsers such as:
- http://some-long-token@localhost:3000/
- http://token:some-long-token@localhost:3000/
Basic Auth specifies a 'Basic' scheme for the Authorization header
similar to how OAuth specifies 'Bearer' as an auth scheme.
Following a similar convention, extract the access token from the
Authorization header when it specifies the 'Basic' scheme, assuming
it is the larger of the <user>:<pass> segments.
This PR removes the instantiation of a new change model
as models return from Change.find are already
instances of Change. This solves the duplicate Id issue #649
Enable authentication for all User unit-tests to check that the ACLs are
correctly configured.
Fix the rule for `confirm` - the correct permission is `ALLOW`, not
`ACL.ALLOW`.
- Move core models `Model` and `PersistedModel` to `lib/`.
- Move `AccessContext` class to `lib/`, since it is not a model.
- Move all other built-in models to `common/models`.
This is a preparation for extracting model definitions to JSON files.
By splitting the change into multiple commits, git is able to keep track
of file moves (renames).
