-# Electron Dev on Codespaces
-
-Welcome to the Codespaces Electron Developer Environment.
-
-## Quick Start
-
-Upon creation of your codespace you should have [build tools](https://github.com/electron/build-tools) installed and an initialized gclient checkout of Electron.  In order to build electron you'll need to run the following commands.
-
-```bash
-e sync -vv
-e build
-```
-
-The initial sync will take approximately ~30 minutes and the build will take ~8 minutes.  Incremental syncs and incremental builds are substantially quicker.
-
-## Directory Structure
-
-Codespaces doesn't lean very well into gclient based checkouts, the directory structure is slightly strange.  There are two locations for the `electron` checkout that both map to the same files under the hood.
-
-```graphql
-# Primary gclient checkout container
-/workspaces/gclient/*
-  └─ src/* - # Chromium checkout
-     └─ electron - # Electron checkout
-# Symlinked Electron checkout (identical to the above)
-/workspaces/electron
-```
-
-## Goma
-
-If you are a maintainer [with Goma access](../docs/development/goma.md) it should be automatically configured and authenticated when you spin up a new codespaces instance.  You can validate this by checking `e d goma_auth info` or by checking that your build-tools configuration has a goma mode of `cluster`.
-
-## Running Electron
-
-You can run Electron in a few ways.  If you just want to see if it launches:
-
-```bash
-# Enter an interactive JS prompt headlessly
-xvfb-run e start -i
-```
-
-But if you want to actually see Electron you will need to use the built-in VNC capability.  If you click "Ports" in codespaces and then open the `VNC web client` forwarded port you should see a web based VNC portal in your browser.  When you are asked for a password use `builduser`.
-
-Once in the VNC UI you can open `Applications -> System -> XTerm` which will open a VNC based terminal app and then you can run `e start` like normal and Electron will open in your VNC session.
-
-## Running Tests
-
-You run tests via build-tools and `xvfb`.
-
-```bash
-# Run all tests
-xvfb-run e test
-
-# Run the main process tests
-xvfb-run e test --runners=main
-
-# Run the old remote tests
-xvfb-run e test --runners=remote
-```

@@ -12,63 +12,6 @@ This document uses the following convention to categorize breaking changes:
 * **Deprecated:** An API was marked as deprecated. The API will continue to function, but will emit a deprecation warning, and will be removed in a future release.
 * **Removed:** An API or feature was removed, and is no longer supported by Electron.
 
-## Planned Breaking API Changes (17.0)
-
-### Removed: `desktopCapturer.getSources` in the renderer
-
-The `desktopCapturer.getSources` API is now only available in the main process.
-This has been changed in order to improve the default security of Electron
-apps.
-
-If you need this functionality, it can be replaced as follows:
-
-```js
-// Main process
-const { ipcMain, desktopCapturer } = require('electron')
-
-ipcMain.handle(
-  'DESKTOP_CAPTURER_GET_SOURCES',
-  (event, opts) => desktopCapturer.getSources(opts)
-)
-```
-
-```js
-// Renderer process
-const { ipcRenderer } = require('electron')
-
-const desktopCapturer = {
-  getSources: (opts) => ipcRenderer.invoke('DESKTOP_CAPTURER_GET_SOURCES', opts)
-}
-```
-
-However, you should consider further restricting the information returned to
-the renderer; for instance, displaying a source selector to the user and only
-returning the selected source.
-
-## Planned Breaking API Changes (16.0)
-
-### Behavior Changed: `crashReporter` implementation switched to Crashpad on Linux
-
-The underlying implementation of the `crashReporter` API on Linux has changed
-from Breakpad to Crashpad, bringing it in line with Windows and Mac. As a
-result of this, child processes are now automatically monitored, and calling
-`process.crashReporter.start` in Node child processes is no longer needed (and
-is not advisable, as it will start a second instance of the Crashpad reporter).
-
-There are also some subtle changes to how annotations will be reported on
-Linux, including that long values will no longer be split between annotations
-appended with `__1`, `__2` and so on, and instead will be truncated at the
-(new, longer) annotation value limit.
-
-### Deprecated: `desktopCapturer.getSources` in the renderer
-
-Usage of the `desktopCapturer.getSources` API in the renderer has been
-deprecated and will be removed. This change improves the default security of
-Electron apps.
-
-See [here](#removed-desktopcapturergetsources-in-the-renderer) for details on
-how to replace this API in your app.

-# Creating a New Electron Browser Module
-
-Welcome to the Electron API guide! If you are unfamiliar with creating a new Electron API module within the [`browser`](https://github.com/electron/electron/tree/main/shell/browser) directory, this guide serves as a checklist for some of the necessary steps that you will need to implement.
-
-This is not a comprehensive end-all guide to creating an Electron Browser API, rather an outline documenting some of the more unintuitive steps.
-
-## Add your files to Electron's project configuration
-
-Electron uses [GN](https://gn.googlesource.com/gn) as a meta build system to generate files for its compiler, [Ninja](https://ninja-build.org/). This means that in order to tell Electron to compile your code, we have to add your API's code and header file names into [`filenames.gni`](https://github.com/electron/electron/blob/main/filenames.gni).
-
-You will need to append your API file names alphabetically into the appropriate files like so:
-
-```cpp title='filenames.gni'
-lib_sources = [
-    "path/to/api/api_name.cc",
-    "path/to/api/api_name.h",
-]
-
-lib_sources_mac = [
-    "path/to/api/api_name_mac.h",
-    "path/to/api/api_name_mac.mm",
-]
-
-lib_sources_win = [
-    "path/to/api/api_name_win.cc",
-    "path/to/api/api_name_win.h",
-]
-
-lib_sources_linux = [
-    "path/to/api/api_name_linux.cc",
-    "path/to/api/api_name_linux.h",
-]
-```
-
-Note that the Windows, macOS and Linux array additions are optional and should only be added if your API has specific platform implementations.
-
-## Create API documentation
-
-Type definitions are generated by Electron using [`@electron/docs-parser`](https://github.com/electron/docs-parser) and [`@electron/typescript-definitions`](https://github.com/electron/typescript-definitions). This step is necessary to ensure consistency across Electron's API documentation. This means that for your API type definition to appear in the `electron.d.ts` file, we must create a `.md` file. Examples can be found in [this folder](https://github.com/electron/electron/tree/main/docs/api).
-
-## Set up `ObjectTemplateBuilder` and `Wrappable`
-
-Electron constructs its modules using [`object_template_builder`](https://www.electronjs.org/blog/from-native-to-js#mateobjecttemplatebuilder).
-
-[`wrappable`](https://chromium.googlesource.com/chromium/src/+/refs/heads/main/gin/wrappable.h) is a base class for C++ objects that have corresponding v8 wrapper objects.
-
-Here is a basic example of code that you may need to add, in order to incorporate `object_template_builder` and `wrappable` into your API. For further reference, you can find more implementations [here](https://github.com/electron/electron/tree/main/shell/browser/api).
-
-In your `api_name.h` file:
-
-```cpp title='api_name.h'
-
-#ifndef SHELL_BROWSER_API_ELECTRON_API_{API_NAME}_H_
-#define SHELL_BROWSER_API_ELECTRON_API_{API_NAME}_H_
-
-#include "gin/handle.h"
-#include "gin/wrappable.h"
-
-namespace electron {
-
-namespace api {
-
-class ApiName : public gin::Wrappable<ApiName>  {
- public:
-  static gin::Handle<ApiName> Create(v8::Isolate* isolate);
-
-  // gin::Wrappable
-  static gin::WrapperInfo kWrapperInfo;
-  gin::ObjectTemplateBuilder GetObjectTemplateBuilder(
-      v8::Isolate* isolate) override;
-  const char* GetTypeName() override;
-} // namespace api
-} // namespace electron
-```
-
-In your `api_name.cc` file:
-
-```cpp title='api_name.cc'
-#include "shell/browser/api/electron_api_safe_storage.h"
-
-#include "shell/browser/browser.h"
-#include "shell/common/gin_converters/base_converter.h"
-#include "shell/common/gin_converters/callback_converter.h"
-#include "shell/common/gin_helper/dictionary.h"
-#include "shell/common/gin_helper/object_template_builder.h"
-#include "shell/common/node_includes.h"
-#include "shell/common/platform_util.h"
-
-namespace electron {
-
-namespace api {
-
-gin::WrapperInfo ApiName::kWrapperInfo = {gin::kEmbedderNativeGin};
-
-gin::ObjectTemplateBuilder ApiName::GetObjectTemplateBuilder(
-    v8::Isolate* isolate) {
-  return gin::ObjectTemplateBuilder(isolate)
-      .SetMethod("methodName", &ApiName::methodName);
-}
-
-const char* ApiName::GetTypeName() {
-  return "ApiName";
-}
-
-// static
-gin::Handle<ApiName> ApiName::Create(v8::Isolate* isolate) {
-  return gin::CreateHandle(isolate, new ApiName());
-}
-
-} // namespace api
-
-} // namespace electron
-
-namespace {
-
-void Initialize(v8::Local<v8::Object> exports,
-                v8::Local<v8::Value> unused,
-                v8::Local<v8::Context> context,
-                void* priv) {
-  v8::Isolate* isolate = context->GetIsolate();
-  gin_helper::Dictionary dict(isolate, exports);
-  dict.Set("apiName", electron::api::ApiName::Create(isolate));
-}
-
-}  // namespace
-```
-
-## Link your Electron API with Node
-
-In the [`typings/internal-ambient.d.ts`](https://github.com/electron/electron/blob/main/typings/internal-ambient.d.ts) file, we need to append a new property onto the `Process` interface like so:
-
-```ts title='typings/internal-ambient.d.ts'
-interface Process {
-    _linkedBinding(name: 'electron_browser_{api_name}', Electron.ApiName);
-}
-```
-
-At the very bottom of your `api_name.cc` file:
-
-```cpp title='api_name.cc'
-NODE_LINKED_MODULE_CONTEXT_AWARE(electron_browser_{api_name},Initialize)
-```
-
-In your [`shell/common/node_bindings.cc`](https://github.com/electron/electron/blob/main/shell/common/node_bindings.cc) file, add your node binding name to Electron's built-in modules.
-
-```cpp title='shell/common/node_bindings.cc'
-#define ELECTRON_BUILTIN_MODULES(V)      \
-  V(electron_browser_{api_name})
-```
-
-> Note: More technical details on how Node links with Electron can be found on [our blog](https://www.electronjs.org/blog/electron-internals-using-node-as-a-library#link-node-with-electron).
-
-## Expose your API to TypeScript
-
-### Export your API as a module
-
-We will need to create a new TypeScript file in the path that follows:
-
-`"lib/browser/api/{electron_browser_{api_name}}.ts"`
-
-An example of the contents of this file can be found [here](https://github.com/electron/electron/blob/main/lib/browser/api/native-image.ts).
-
-### Expose your module to TypeScript
-
-Add your module to the module list found at `"lib/browser/api/module-list.ts"` like so:
-
-```typescript title='lib/browser/api/module-list.ts'
-export const browserModuleList: ElectronInternal.ModuleEntry[] = [
-  { name: 'apiName', loader: () => require('./api-name') },
-];
-```

-## Using Playwright
-
-[Microsoft Playwright](https://playwright.dev) is an end-to-end testing framework built
-using browser-specific remote debugging protocols, similar to the [Puppeteer] headless
-Node.js API but geared towards end-to-end testing. Playwright has experimental Electron
-support via Electron's support for the [Chrome DevTools Protocol] (CDP).
-
-### Install dependencies
-
-You can install Playwright through your preferred Node.js package manager. The Playwright team
-recommends using the `PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD` environment variable to avoid
-unnecessary browser downloads when testing an Electron app.
-
-```sh npm2yarn
-PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1 npm install --save-dev playwright
-```
-
-Playwright also comes with its own test runner, Playwright Test, which is built for end-to-end
-testing. You can also install it as a dev dependency in your project:
-
-```sh npm2yarn
-npm install --save-dev @playwright/test
-```
-
-:::caution Dependencies
-This tutorial was written `playwright@1.16.3` and `@playwright/test@1.16.3`. Check out
-[Playwright's releases][playwright-releases] page to learn about
-changes that might affect the code below.
-:::
-
-:::info Using third-party test runners
-If you're interested in using an alternative test runner (e.g. Jest or Mocha), check out
-Playwright's [Third-Party Test Runner][playwright-test-runners] guide.
-:::
-
-### Write your tests
-
-Playwright launches your app in development mode through the `_electron.launch` API.
-To point this API to your Electron app, you can pass the path to your main process
-entry point (here, it is `main.js`).
-
-```js {5}
-const { _electron: electron } = require('playwright')
-const { test } = require('@playwright/test')
-
-test('launch app', async () => {
-  const electronApp = await electron.launch({ args: ['main.js'] })
-  // close app
-  await electronApp.close()
-})
-```
-
-After that, you will access to an instance of Playwright's `ElectronApp` class. This
-is a powerful class that has access to main process modules for example:
-
-```js {6-11}
-const { _electron: electron } = require('playwright')
-const { test } = require('@playwright/test')
-
-test('get isPackaged', async () => {
-  const electronApp = await electron.launch({ args: ['main.js'] })
-  const isPackaged = await electronApp.evaluate(async ({ app }) => {
-    // This runs in Electron's main process, parameter here is always
-    // the result of the require('electron') in the main app script.
-    return app.isPackaged
-  })
-  console.log(isPackaged) // false (because we're in development mode)
-  // close app
-  await electronApp.close()
-})
-```
-
-It can also create individual [Page][playwright-page] objects from Electron BrowserWindow instances.
-For example, to grab the first BrowserWindow and save a screenshot:
-
-```js {6-7}
-const { _electron: electron } = require('playwright')
-const { test } = require('@playwright/test')
-
-test('save screenshot', async () => {
-  const electronApp = await electron.launch({ args: ['main.js'] })
-  const window = await electronApp.firstWindow()
-  await window.screenshot({ path: 'intro.png' })
-  // close app
-  await electronApp.close()
-})
-```
-
-Putting all this together using the PlayWright Test runner, let's create a `example.spec.js`
-test file with a single test and assertion:
-
-```js title='example.spec.js'
-const { _electron: electron } = require('playwright')
-const { test, expect } = require('@playwright/test')
-
-test('example test', async () => {
-  const electronApp = await electron.launch({ args: ['.'] })
-  const isPackaged = await electronApp.evaluate(async ({ app }) => {
-    // This runs in Electron's main process, parameter here is always
-    // the result of the require('electron') in the main app script.
-    return app.isPackaged;
-  });
-
-  expect(isPackaged).toBe(false);
-
-  // Wait for the first BrowserWindow to open
-  // and return its Page object
-  const window = await electronApp.firstWindow()
-  await window.screenshot({ path: 'intro.png' })
-
-  // close app
-  await electronApp.close()
-});
-```
-
-Then, run Playwright Test using `npx playwright test`. You should see the test pass in your
-console, and have an `intro.png` screenshot on your filesystem.
-
-```console
-☁  $ npx playwright test
-
-Running 1 test using 1 worker
-
-  ✓  example.spec.js:4:1 › example test (1s)
-```
-
-:::info
-Playwright Test will automatically run any files matching the `.*(test|spec)\.(js|ts|mjs)` regex.
-You can customize this match in the [Playwright Test configuration options][playwright-test-config].
-:::

-:::tip Further reading
-Check out Playwright's documentation for the full [Electron][playwright-electron]
-and [ElectronApplication][playwright-electronapplication] class APIs.

-Subject: M99: Vulkan: Fix texture array level redefinition
-
-When a level of a texture is redefined, all staged updates to that level
-should be removed, not the ones specific to the new layers.  The bug
-fixed was that if the texture was redefined to have its number of layers
-changed, the staged higher-layer-count update to the image was not
-removed.

+Subject: Ignore the pixel unpack state for compressed textures.
+
+From OpenGL ES 3 spec: All pixel storage modes are ignored when decoding
+a compressed texture image
+This was causing a bad access when calling compressedTexImage3D
+with GL_UNPACK_IMAGE_HEIGHT greater than the image height.
