-
-This document describes the new protocol APIs based on the [NetworkService](https://www.chromium.org/servicification).
-
-We don't currently have an estimate of when we will enable the `NetworkService` by
-default in Electron, but as Chromium is already removing non-`NetworkService`
-code, we will probably switch before Electron 10.
-
-The content of this document should be moved to `protocol.md` after we have
-enabled the `NetworkService` by default in Electron.
-
-> Register a custom protocol and intercept existing protocol requests.
-
-Process: [Main](../glossary.md#main-process)
-
-An example of implementing a protocol that has the same effect as the
-`file://` protocol:
-
-```javascript
-const { app, protocol } = require('electron')
-const path = require('path')
-
-app.whenReady().then(() => {
-  protocol.registerFileProtocol('atom', (request, callback) => {
-    const url = request.url.substr(7)
-    callback({ path: path.normalize(`${__dirname}/${url}`) })
-  })
-})
-```
-
-**Note:** All methods unless specified can only be used after the `ready` event
-of the `app` module gets emitted.
-
-## Using `protocol` with a custom `partition` or `session`
-
-A protocol is registered to a specific Electron [`session`](./session.md)
-object. If you don't specify a session, then your `protocol` will be applied to
-the default session that Electron uses. However, if you define a `partition` or
-`session` on your `browserWindow`'s `webPreferences`, then that window will use
-a different session and your custom protocol will not work if you just use
-`electron.protocol.XXX`.
-
-To have your custom protocol work in combination with a custom session, you need
-to register it to that session explicitly.
-
-```javascript
-const { session, app, protocol } = require('electron')
-const path = require('path')
-
-app.whenReady().then(() => {
-  const partition = 'persist:example'
-  const ses = session.fromPartition(partition)
-
-  ses.protocol.registerFileProtocol('atom', (request, callback) => {
-    const url = request.url.substr(7)
-    callback({ path: path.normalize(`${__dirname}/${url}`) })
-  })
-
-  mainWindow = new BrowserWindow({ webPreferences: { partition } })
-})
-```
-
-## Methods
-
-The `protocol` module has the following methods:
-
-### `protocol.registerSchemesAsPrivileged(customSchemes)`
-
-* `customSchemes` [CustomScheme[]](structures/custom-scheme.md)
-
-**Note:** This method can only be used before the `ready` event of the `app`
-module gets emitted and can be called only once.
-
-Registers the `scheme` as standard, secure, bypasses content security policy for
-resources, allows registering ServiceWorker and supports fetch API. Specify a
-privilege with the value of `true` to enable the capability.
-
-An example of registering a privileged scheme, that bypasses Content Security
-Policy:
-
-```javascript
-const { protocol } = require('electron')
-protocol.registerSchemesAsPrivileged([
-  { scheme: 'foo', privileges: { bypassCSP: true } }
-])
-```
-
-A standard scheme adheres to what RFC 3986 calls [generic URI
-syntax](https://tools.ietf.org/html/rfc3986#section-3). For example `http` and
-`https` are standard schemes, while `file` is not.
-
-Registering a scheme as standard allows relative and absolute resources to
-be resolved correctly when served. Otherwise the scheme will behave like the
-`file` protocol, but without the ability to resolve relative URLs.
-
-For example when you load following page with custom protocol without
-registering it as standard scheme, the image will not be loaded because
-non-standard schemes can not recognize relative URLs:
-
-```html
-<body>
-  <img src='test.png'>
-</body>
-```
-
-Registering a scheme as standard will allow access to files through the
-[FileSystem API][file-system-api]. Otherwise the renderer will throw a security
-error for the scheme.
-
-By default web storage apis (localStorage, sessionStorage, webSQL, indexedDB,
-cookies) are disabled for non standard schemes. So in general if you want to
-register a custom protocol to replace the `http` protocol, you have to register
-it as a standard scheme.
-
-### `protocol.registerFileProtocol(scheme, handler)`
-
-* `scheme` String
-* `handler` Function
-  * `request` ProtocolRequest
-  * `callback` Function
-    * `response` (String | [ProtocolResponse](structures/protocol-response.md))
-
-Registers a protocol of `scheme` that will send a file as the response. The
-`handler` will be called with `request` and `callback` where `request` is
-an incoming request for the `scheme`.
-
-To handle the `request`, the `callback` should be called with either the file's
-path or an object that has a `path` property, e.g. `callback(filePath)` or
-`callback({ path: filePath })`. The `filePath` must be an absolute path.
-
-By default the `scheme` is treated like `http:`, which is parsed differently
-from protocols that follow the "generic URI syntax" like `file:`.
-
-### `protocol.registerBufferProtocol(scheme, handler)`
-
-* `scheme` String
-* `handler` Function
-  * `request` ProtocolRequest
-  * `callback` Function
-    * `response` (Buffer | [ProtocolResponse](structures/protocol-response.md))
-
-Registers a protocol of `scheme` that will send a `Buffer` as a response.
-
-The usage is the same with `registerFileProtocol`, except that the `callback`
-should be called with either a `Buffer` object or an object that has the `data`
-property.
-
-Example:
-
-```javascript
-protocol.registerBufferProtocol('atom', (request, callback) => {
-  callback({ mimeType: 'text/html', data: Buffer.from('<h5>Response</h5>') })
-})
-```
-
-### `protocol.registerStringProtocol(scheme, handler)`
-
-* `scheme` String
-* `handler` Function
-  * `request` ProtocolRequest
-  * `callback` Function
-    * `response` (String | [ProtocolResponse](structures/protocol-response.md))
-
-Registers a protocol of `scheme` that will send a `String` as a response.
-
-The usage is the same with `registerFileProtocol`, except that the `callback`
-should be called with either a `String` or an object that has the `data`
-property.
-
-### `protocol.registerHttpProtocol(scheme, handler)`
-
-* `scheme` String
-* `handler` Function
-  * `request` ProtocolRequest
-  * `callback` Function
-    * `response` ProtocolResponse
-
-Registers a protocol of `scheme` that will send an HTTP request as a response.
-
-The usage is the same with `registerFileProtocol`, except that the `callback`
-should be called with an object that has the `url` property.
-
-### `protocol.registerStreamProtocol(scheme, handler)`
-
-* `scheme` String
-* `handler` Function
-  * `request` ProtocolRequest
-  * `callback` Function
-    * `response` (ReadableStream | [ProtocolResponse](structures/protocol-response.md))
-
-Registers a protocol of `scheme` that will send a stream as a response.
-
-The usage is the same with `registerFileProtocol`, except that the
-`callback` should be called with either a [`ReadableStream`](https://nodejs.org/api/stream.html#stream_class_stream_readable) object or an object that
-has the `data` property.
-
-Example:
-
-```javascript
-const { protocol } = require('electron')
-const { PassThrough } = require('stream')
-
-function createStream (text) {
-  const rv = new PassThrough() // PassThrough is also a Readable stream
-  rv.push(text)
-  rv.push(null)
-  return rv
-}
-
-protocol.registerStreamProtocol('atom', (request, callback) => {
-  callback({
-    statusCode: 200,
-    headers: {
-      'content-type': 'text/html'
-    },
-    data: createStream('<h5>Response</h5>')
-  })
-})
-```
-
-It is possible to pass any object that implements the readable stream API (emits
-`data`/`end`/`error` events). For example, here's how a file could be returned:
-
-```javascript
-protocol.registerStreamProtocol('atom', (request, callback) => {
-  callback(fs.createReadStream('index.html'))
-})
-```

-* `scheme` String
-* `handler` Function
-  * `request` ProtocolRequest
-  * `callback` Function
-    * `response` (String | [ProtocolResponse](structures/protocol-response.md))

+Subject: Allow focus to move into an editable combobox's listbox
+
+In bug 593646 (https://codereview.chromium.org/2024053003/) a rule was
+added, apparently similar to a rule in WebKit, that prevents
+aria-activedescendant on an editable combobox field from moving focus
+into its listbox. However, removing this condition fixes an issue where
+the first item is not read. It also improves the verbalization,
+providing the user with the positional info, e.g. "2 of 5".
+Removing this line also does not seem to break the example attached to
+bug 593646.

-Override MediaKeysListener::IsMediaKeycode to also listen for Volume Up, Volume Down,

-control events until it begins playing audio. This means that a media shortcut would not kick
-into effect until you, for example, began playing a YouTube video which sort of defeats the
-purpose of GlobalShortcuts.

-At the moment there is no upstream possibility for this; but perhaps Chromium may

+Date: Tue, 18 Aug 2020 18:42:09 +0000
+Subject: Counters: Only update ancestors if style boundary is crossed.
+
+This patch is an optimization patch that ensures that we only update
+ancestor counters if we have crossed a style containment boundary.
+
+The update is required since otherwise counters and content fields
+that are separated by a style boundary don't behave correctly (we
+elide updating counters if there is no content present; and then we
+stop updates when they cross a style boundary). However, this update
+is only needed on the other side of the containment boundary (and indeed
+if there is a style containment boundary).

-Subject: allow embedder to set crash upload url
-
-Currently //components/crash hard-codes the crash report URL to be a
-Google-specific target. This CL adds a hook which allows embedders to override
-this URL. Without it, this module isn't usable for non-Google embedders.

patches/chromium/disable_compositor_recycling.patch

@@ -6,10 +6,10 @@ Subject: fix: disabling compositor recycling
 Compositor recycling is useful for Chrome because there can be many tabs and spinning up a compositor for each one would be costly. In practice, Chrome uses the parent compositor code path of browser_compositor_view_mac.mm; the NSView of each tab is detached when it's hidden and attached when it's shown. For Electron, there is no parent compositor, so we're forced into the "own compositor" code path, which seems to be non-optimal and pretty ruthless in terms of the release of resources. Electron has no real concept of multiple tabs per window, so it should be okay to disable this ruthless recycling altogether in Electron.

+Subject: fix: swap global proxies before initializing the windows proxies
+
+Electron's Context Isolation implementation has a side-effect of initializing
+the isolated worlds WindowProxy during the initialization of the main world
+WindowProxy as a result of creating the isolated world inside the DidCreateScriptContext
+hook.  This results in an assertion failing in Chromium during a frame
+swap where it expects to be able to set a new global_proxy in the WindowProxy
+of the isolated world BEFORE it is initialized.
+
+To meet this assumption this patch splits SetGlobalProxy into two calls,
+SetGlobalProxyWithoutInitializing and InitializeIfNeeded which has the same
+resultant effect but means that all of the global_proxy objects are set
+BEFORE any WindowProxy's are initialized.
+
+This could probably be upstreamed as it doesn't affect the way Chromium works
+but also it has no benefit for them at this time.
