* Don't use JSON to send the result of `ipcRenderer.sendSync`.
- Change the return type of AtomViewHostMsg_Message_Sync from `base::string16`
to `base::ListValue`
- Adjust lib/browser/api/web-contents.js and /lib/renderer/api/ipc-renderer.js
to wrap/unwrap return values to/from array, instead of
serializing/deserializing JSON.
This change can greatly improve `ipcRenderer.sendSync` calls where the return
value contains Buffer instances, because those are converted to Array before
being serialized to JSON(which has no efficient way of representing byte
arrays).
A simple benchmark where remote.require('fs') was used to read a 16mb file got
at least 5x faster, not to mention it used a lot less memory. This difference
tends increases with larger buffers.
* Don't base64 encode Buffers
* Don't allocate V8ValueConverter on the heap
* Replace hidden global.sandbox with NodeBindings::IsInitialized()
* Refactoring: check NodeBindings::IsInitialized() in V8ValueConverter
* Refactor problematic test to make it more reliable
* Add tests for NaN and Infinity
Use a single synchronous IPC call to retrieve data required by early
sandbox scripts. This has two purposes:
- Optimize preload script initialization by:
- Using one synchronous IPC call to retrieve preload script,
webContentsId (more on that later), process.{platform,execPath,env}
- Lazy loading as many modules as possible.
- Fix#12316 for sandbox. @MarshallOfSound addressed the issue in
#12342, but it was still present in sandbox mode. By loading
webContentsId very early and skipping remote module at early
startup, we fix it for sandbox.
When the Chrome Extension has too many content scripts (above default
10 counts), there will be a warning: possible EventEmitter memory leak
detected. 11 listeners added.
* add did-frame-navigate event to WebContents, pass http response code to it and did-navigate
* docs for frame routing id related api changes on WebFrame and WebContents
* expose WebFrame#routingId and pass it to WebContents frame specific events along with frameProcessId; add WebContets.did-start-navigation event
* fix compilation error on ia32 Windows
* add cause property to exception in callFunction
* update exceptionToMeta function
* add sender argument
* and cause property to return value
* update exception convert in metaToValue function
* add from and cause properties to the exception error
* unit test for remote exception
* Add a screen_api_id parameter to the desktopCapturer API.
When using the DirectX capturer on Windows, there was previously no way
to associate desktopCapturer/getUserMedia and electron.screen API
screens. This new parameter provides the association.
* Fix non-Windows build.
* Fix Mac.
* Fix Mac harder.
* JS lint
* clang-format C++ code.
* IWYU
* display_id, Linux comment, better test
* lint
* Fix tests on Linux.
* Add display_id documentation.
* Remove the race condition between new process creation and old process releasing remote context
Previously there was a race condition where the getId() method would return the new context ID even
though the release was for the old context. This changes it to send the "initial" context ID with
the release message to ensure there is no race.
* fetch context ID from remote in sandbox mode
* Persist defaults to webPreferences object to JS land can read the inferred values instead of just user defined values
* Test inherited default propogation
* Refactor to remove coupling from fetching values and defaults
* Test description type
* Fix up tests
* This is to enable more browser-like behavior so that users who run third-party code
will not be DOS'ed with alerts and confirms. This is already handled like this
in most major browsers so this will greatly help these developers
* 🔧 Add security issue detection (and logs)
* 🔧 Check for it on load

Chromium already includes the necessary plumbing to manage the
visibility properties and `visibilitychange` event so this gets rid of
most of our custom logic for `BrowserWindow` and `BrowserView`.
Note that `webview` remains unchanged and is still affected by the issues
listed below.
User facing changes:
- The `document` visibility properties and `visibilitychange` event are
now also updated/fired in response to occlusion changes on macOS. In
other words, `document.visibilityState` will now be `hidden` on macOS
if the window is occluded by another window.
- Previously, `visibilitychange` was also fired by *both* Electron and
Chromium in some cases (e.g. when hiding the window). Now it is only
fired by Chromium so you no longer get duplicate events.
- The visiblity state of `BrowserWindow`s created with `{ show: false }`
is now initially `visible` until the window is shown and hidden.
- The visibility state of `BrowserWindow`s with `backgroundThrottling`
disabled is now permanently `visible`.
This should also fix#6860 (but not for `webview`).
In addition to listening for "render-view-deleted", listen for
"ELECTRON_BROWSER_CONTEXT_RELEASE" synchronous message, which is sent by the
remote module when the page is about to be navigated.
This is required to allow child windows running in the same renderer to
correctly manage remote object references, since `render-view-deleted` is only
called when the renderer exits.
Close#9387
