After the page does navigations, garbage collection can still happen in
the old context. This commit changes to store references to remote objects
by _pages_, instead of by _WebContents_.
* Make it possible to disable a module for a renderer
* Put DesktopCapturer API under a build flag
The name is "enable_desktop_capturer".
Enabled by default.
* 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.
* 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
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
