@ -17,10 +17,21 @@ The bridge
==========
`"Golden Gate" <https://searchfox.org/mozilla-central/source/services/sync/golden_gate>`_
was previously used to help bridge any Rust implemented Sync engines with desktop,
but most of that logic has been removed. The integration of `UniFFI <https://github.com/mozilla/uniffi-rs>`_-ed components
made the Golden Gate bridge code obsolete. Currently Golden Gate contains the
logging logic for the components and the bridged engines exist in application
services within the respective sync components. For instance, these are bridged
engines for `tabs <https://github.com/mozilla/application-services/blob/main/components/tabs/src/sync/bridge.rs>`_ and
`webext-storage <https://github.com/mozilla/application-services/blob/main/components/webext-storage/src/sync/bridge.rs>`_.
is a utility to help bridge any Rust implemented Sync engines with desktop. In
other words, it's a "rusty bridge" - get it? Get it? Yet another of Lina's puns
that live on!
One of the key challenges with integrating a Rust Sync component with desktop
is the different threading models. The Rust code tends to be synchronous -
most functions block the calling thread to do the disk or network IO necessary
to work - it assumes that the consumer will delegate this to some other thread.
So golden_gate is this background thread delegation for a Rust Sync engine -
gecko calls golden-gate on the main thread, it marshalls the call to a worker
thread, and the result is marshalled back to the main thread.
It's worth noting that golden_gate is just for the Sync engine part - other
parts of the component (ie, the part that provides the functionality that's not
sync related) will have its own mechanism for this. For example, the
`webext-storage bridge <https://searchfox.org/mozilla-central/source/toolkit/components/extensions/storage/webext_storage_bridge/src>`_
uses a similar technique `which has some in-depth documentation <../../toolkit/components/extensions/webextensions/webext-storage.html>`_.

//! **Golden Gate** 🌉 was created to bridge Desktop Sync to our suite of
//! Rust sync and storage components. But the UniFFI-cation of our
//! components made much of Golden Gate's logic obsolete. It is now mainly
//! a means to access LogSink, the logger for our components.
//! **Golden Gate** 🌉 is a crate for bridging Desktop Sync to our suite of
//! Rust sync and storage components. It connects Sync's `BridgedEngine` class
//! to the Rust `BridgedEngine` trait via the `mozIBridgedSyncEngine` XPCOM
//! interface.
//!
//! Due to limitations in implementing XPCOM interfaces for generic types,
//! Golden Gate doesn't implement `mozIBridgedSyncEngine` directly. Instead,
//! it provides helpers, called "ferries", for passing Sync records between
//! JavaScript and Rust. The ferries also handle threading and type
//! conversions.
//!
//! Here's a step-by-step guide for adding a new Rust Sync engine to Firefox.
//!
//! ## Step 1: Create your (XPCOM) bridge
//!
//! In your consuming crate, define a type for your `mozIBridgedSyncEngine`
//! implementation. We'll call this type the **brige**. The bridge is
//! responsible for exposing your Sync engine to XPIDL [^1], in a way that lets
//! JavaScript call it.
//!
//! For your bridge type, you'll need to implement an xpcom interface with the
//! `#[xpcom(implement(mozIBridgedSyncEngine), nonatomic)]` attribute then
//! define `xpcom_method!()` stubs for the `mozIBridgedSyncEngine` methods. For
//! more details about implementing XPCOM methods in Rust, check out the docs in
//! `xpcom/rust/xpcom/src/method.rs`.
//!
//! You'll also need to add an entry for your bridge type to `components.conf`,
//! and define C++ and Rust constructors for it, so that JavaScript code can
//! create instances of it. Check out `NS_NewWebExtStorage` (and, in C++,
//! `mozilla::extensions::storageapi::NewWebExtStorage`) and
//! `NS_NewSyncedBookmarksMerger` (`mozilla::places::NewSyncedBookmarksMerger`
//! in C++) for how to do this.
//!
//! [^1]: You can think of XPIDL as a souped-up C FFI, with richer types and a
//! degree of type safety.
//!
//! ## Step 2: Add a background task queue to your bridge
//!
//! A task queue lets your engine do I/O, merging, and other syncing tasks on a
//! background thread pool. This is important because database reads and writes
//! can take an unpredictable amount of time. Doing these on the main thread can
//! cause jank, and, in the worst case, lock up the browser UI for seconds at a
//! time.
//!
//! The `moz_task` crate provides a `create_background_task_queue` function to
//! do this. Once you have a queue, you can use it to call into your Rust
//! engine. Golden Gate takes care of ferrying arguments back and forth across
//! the thread boundary.
//!
//! Since it's a queue, ferries arrive in the order they're scheduled, so
//! your engine's `store_incoming` method will always be called before `apply`,
//! which is likewise called before `set_uploaded`. The thread manager scales
//! the pool for you; you don't need to create or manage your own threads.
//!
//! ## Step 3: Create your Rust engine
//!
//! Next, you'll need to implement the Rust side of the bridge. This is a type
//! that implements the `BridgedEngine` trait.
//!
//! Bridged engines handle storing incoming Sync records, merging changes,
//! resolving conflicts, and fetching outgoing records for upload. Under the
//! hood, your engine will hold either a database connection directly, or
//! another object that does.
//!
//! Although outside the scope of Golden Gate, your engine will also likely
//! expose a data storage API, for fetching, updating, and deleting items
//! locally. Golden Gate provides the syncing layer on top of this local store.
//!
//! A `BridgedEngine` itself doesn't need to be `Send` or `Sync`, but the
//! ferries require both, since they're calling into your bridge on the
//! background task queue.
//!
//! In practice, this means your bridge will need to hold a thread-safe owned
//! reference to the engine, via `Arc<Mutex<BridgedEngine>>`. In fact, this
//! pattern is so common that Golden Gate implements `BridgedEngine` for any
//! `Mutex<BridgedEngine>`, which automatically locks the mutex before calling
//! into the engine.
//!
//! ## Step 4: Connect the bridge to the JavaScript and Rust sides
//!
//! On the JavaScript side, you'll need to subclass Sync's `BridgedEngine`
//! class, and give it a handle to your XPCOM bridge. The base class has all the
//! machinery for hooking up any `mozIBridgedSyncEngine` implementation so that
//! Sync can drive it.
//!
//! On the Rust side, each `mozIBridgedSyncEngine` method should create a
//! Golden Gate ferry, and dispatch it to the background task queue. The
//! ferries correspond to the method names. For example, `ensureCurrentSyncId`
//! should create a `Ferry::ensure_current_sync_id(...)`; `storeIncoming`, a
//! `Ferry::store_incoming(...)`; and so on. This is mostly boilerplate.
//!
//! And that's it! Each ferry will, in turn, call into your Rust
//! `BridgedEngine`, and send the results back to JavaScript.
//!
//! For an example of how all this works, including exposing a storage (not
//! just syncing!) API to JS via XPIDL, check out `webext_storage::Bridge` for
//! the `storage.sync` API!

Note: The general mechanism described below is also used for other Rust components from the
app-services team - for example, "dogear" uses a similar mechanism, and the sync engines
too (but with even more complexity) to manage the threads. Unfortunately, at time of writing,
no code is shared and it's not clear how we would, but this might change as more Rust lands.
The app-services component `lives on github <https://github.com/mozilla/application-services/blob/main/components/webext-storage>`_.
There are docs that describe `how to update/vendor this (and all) external rust code <../../../../build/buildsystem/rust.html>`_ you might be interested in.
We use UniFFI to generate JS bindings for the components. More details about UniFFI can be found in `these docs <https://searchfox.org/mozilla-central/source/docs/writing-rust-code/uniffi.md>`_.

This class/module has complexity for things like migration from the earlier Kinto-based backend,
but importantly, code to adapt a callback API into a promise based one.
Overview of the API
###################
@ -34,3 +57,171 @@ The semantics of the API are beyond this doc but are
As you will see in those docs, the API is promise-based, but the rust implementation is fully
synchronous and Rust knows nothing about Javascript promises - so this system converts
the callback-based API to a promise-based one.
xpcom as the interface to Rust
##############################
xpcom is old Mozilla technology that uses C++ "vtables" to implement "interfaces", which are
described in IDL files. While this traditionally was used to interface
C++ and Javascript, we are leveraging existing support for Rust. The interface we are
exposing is described in `mozIExtensionStorageArea.idl <https://searchfox.org/mozilla-central/source/toolkit/components/extensions/storage/mozIExtensionStorageArea.idl>`_
The main interface of interest in this IDL file is `mozIExtensionStorageArea`.
This interface defines the functionality - and is the first layer in the sync to async model.
For example, this interface defines the following method:
.. code-block:: rust
interface mozIExtensionStorageArea : nsISupports {
...
// Sets one or more key-value pairs specified in `json` for the
// `extensionId`...
void set(in AUTF8String extensionId,
in AUTF8String json,
in mozIExtensionStorageCallback callback);
As you will notice, the 3rd arg is another interface, `mozIExtensionStorageCallback`, also
defined in that IDL file. This is a small, generic interface defined as:
.. code-block:: cpp
interface mozIExtensionStorageCallback : nsISupports {
// Called when the operation completes. Operations that return a result,
// like `get`, will pass a `UTF8String` variant. Those that don't return
// anything, like `set` or `remove`, will pass a `null` variant.
void handleSuccess(in nsIVariant result);
// Called when the operation fails.
void handleError(in nsresult code, in AUTF8String message);
};
Note that this delivers all results and errors, so must be capable of handling
every result type, which for some APIs may be problematic - but we are very lucky with this API
that this simple XPCOM callback interface is capable of reasonably representing the return types
from every function in the `mozIExtensionStorageArea` interface.
(There's another interface, `mozIExtensionStorageListener` which is typically
also implemented by the actual callback to notify the extension about changes,
but that's beyond the scope of this doc.)
*Note the thread model here is async* - the `set` call will return immediately, and later, on
the main thread, we will call the callback param with the result of the operation.
So under the hood, what happens is something like:
.. mermaid::
sequenceDiagram
Extension->>ExtensionStorageSync: call `set` and give me a promise
ExtensionStorageSync->>xpcom: call `set`, supplying new data and a callback
ExtensionStorageSync-->>Extension: your promise
xpcom->>xpcom: thread magic in the "bridge"
xpcom-->>ExtensionStorageSync: callback!
ExtensionStorageSync-->>Extension: promise resolved
So onto the thread magic in the bridge!
webext_storage_bridge
#####################
The `webext_storage_bridge <https://searchfox.org/mozilla-central/source/toolkit/components/extensions/storage/webext_storage_bridge>`_
is a Rust crate which, as implied by the name, is a "bridge" between this Javascript/XPCOM world to
the actual `webext-storage <https://github.com/mozilla/application-services/tree/main/components/webext-storage>`_ crate.
lib.rs
------
Is the entry-point - it defines the xpcom "factory function" -
an `extern "C"` function which is called by xpcom to create the Rust object
implementing `mozIExtensionStorageArea` using existing gecko support.
area.rs
-------
This module defines the interface itself. For example, inside that file you will find:
.. code-block:: rust
impl StorageSyncArea {
...
xpcom_method!(
set => Set(
ext_id: *const ::nsstring::nsACString,
json: *const ::nsstring::nsACString,
callback: *const mozIExtensionStorageCallback
)
);
/// Sets one or more key-value pairs.
fn set(
&self,
ext_id: &nsACString,
json: &nsACString,
callback: &mozIExtensionStorageCallback,
) -> Result<()> {
self.dispatch(
Punt::Set {
ext_id: str::from_utf8(&*ext_id)?.into(),
value: serde_json::from_str(str::from_utf8(&*json)?)?,
},
callback,
)?;
Ok(())
}
Of interest here:
* `xpcom_method` is a Rust macro, and part of the existing xpcom integration which already exists
in gecko. It declares the xpcom vtable method described in the IDL.
* The `set` function is the implementation - it does string conversions and the JSON parsing
on the main thread, then does the work via the supplied callback param, `self.dispatch` and a `Punt`.
* The `dispatch` method dispatches to another thread, leveraging existing in-tree `moz_task <https://searchfox.org/mozilla-central/source/xpcom/rust/moz_task>`_ support, shifting the `Punt` to another thread and making the callback when done.
Punt
----
`Punt` is a whimsical name somewhat related to a "bridge" - it carries things across and back.
It is a fairly simple enum in `punt.rs <https://searchfox.org/mozilla-central/source/toolkit/components/extensions/storage/webext_storage_bridge/src/punt.rs>`_.
It's really just a restatement of the API we expose suitable for moving across threads. In short, the `Punt` is created on the main thread,
then sent to the background thread where the actual operation runs via a `PuntTask` and returns a `PuntResult`.
There's a few dances that go on, but the end result is that `inner_run() <https://searchfox.org/mozilla-central/source/toolkit/components/extensions/storage/webext_storage_bridge/src/punt.rs>`_
gets executed on the background thread - so for `Set`:
.. code-block:: rust
Punt::Set { ext_id, value } => {
PuntResult::with_change(&ext_id, self.store()?.get()?.set(&ext_id, value)?)?
}
Here, `self.store()` is a wrapper around the actual Rust implementation from app-services with
various initialization and mutex dances involved - see `store.rs`.
ie, this function is calling our Rust implementation and stashing the result in a `PuntResult`
The `PuntResult` is private to that file but is a simple struct that encapsulates both
the actual result of the function (also a set of changes to send to observers, but that's
beyond this doc).
Ultimately, the `PuntResult` ends up back on the main thread once the call is complete
and arranges to callback the JS implementation, which in turn resolves the promise created in `ExtensionStorageSync.sys.mjs`
End result:
-----------

* `components.conf` has two classes:
* `@mozilla.org/extensions/storage/internal/sync-area;1` and

*
* The `storage/internal/sync-area;1` class is implemented in Rust, and can be
* instantiated using `createInstance` and `Components.Constructor`. It's not
* a singleton, so creating a new instance will create a new `storage.sync`
* area, with its own database connection. It's useful for testing, but not
* meant to be used outside of this module.
*
* The `storage/sync;1` class is implemented in this file. It's a singleton,
* ensuring there's only one `storage.sync` area, with one database connection.
* The service implements `nsIInterfaceRequestor`, so callers can access the
* storage interface like this:
*
* let storageSyncArea = Cc["@mozilla.org/extensions/storage/sync;1"]
* .getService(Ci.nsIInterfaceRequestor)
* .getInterface(Ci.mozIExtensionStorageArea);

#![allow(non_snake_case)]
//! This crate bridges the WebExtension storage area interfaces in Firefox
//! Desktop to the extension storage Rust component in Application Services.
//!
//! ## How are the WebExtension storage APIs implemented in Firefox?
//!
//! There are three storage APIs available for WebExtensions:
//! `storage.local`, which is stored locally in an IndexedDB database and never
//! synced to other devices, `storage.sync`, which is stored in a local SQLite
//! database and synced to all devices signed in to the same Firefox Account,
//! and `storage.managed`, which is provisioned in a native manifest and
//! read-only.
//!
//! * `storage.local` is implemented in `ExtensionStorageIDB.sys.mjs`.
//! * `storage.sync` is implemented in a Rust component, `webext_storage`. This
//! Rust component is vendored in m-c, and exposed to JavaScript via an XPCOM
//! API in `webext_storage_bridge` (this crate). Eventually, we'll change
//! `ExtensionStorageSync.sys.mjs` to call the XPCOM API instead of using the
//! old Kinto storage adapter.
//! * `storage.managed` is implemented directly in `parent/ext-storage.js`.
//!
//! `webext_storage_bridge` implements the `mozIExtensionStorageArea`
//! (and, eventually, `mozIBridgedSyncEngine`) interface for `storage.sync`. The
//! implementation is in `area::StorageSyncArea`, and is backed by the
//! `webext_storage` component.
