* refactor: bundle the browser and renderer process electron code
* Bundles browser/init and renderer/init
* Improves load performance of main process by ~40%
* Improves load performance of renderer process by ~30%
* Prevents users from importing our "requiring" our internal logic such
as ipc-main-internal. This makes those message buses safer as they are
less accessible, there is still some more work to be done though to lock
down those buses completely.
* The electron.asar file now only contains 2 files, as a future
improvement maybe we can use atom_natives to ship these two files
embedded in the binary
* This also removes our dependency on browserify which had some strange
edge cases that caused us to have to hack around require-order and
stopped us using certain ES6/7 features we should have been able to use
(async / await in some files in the sandboxed renderer init script)
TLDR: Things are faster and better :)
* fix: I really do not want to talk about it
* chore: add performance improvements from debugging
* fix: resolve the provided path so webpack thinks it is absolute
* chore: fixup per PR review
* fix: use webpacks ProvidePlugin to keep global, process and Buffer alive after deletion from global scope for use in internal code
* fix: bundle worker/init as well to make node-in-workers work
* chore: update wording as per feedback
* chore: make the timers hack work when yarn is not used
* spec: clean up after a failed window count assertion
Previously when this assertion failed all tests that ran after the
failed assertion also failed. This ensure that the assertion fails for
the test that actually caused the issue but cleans up the left-over
windows so that future tests do not fail.
* fix: maintain a ref count for objects sent over remote
Previously there was a race condition where a GC could occur in the
renderer process between the main process sending a meta.id and the
renderer pulling the proxy out its weakmap to stop it being GC'ed.
This fixes that race condition by maintaining a "sent" ref count in the
object registry and a "received" ref count in the object cache on the
renderer side. The deref request now sends the number of refs the
renderer thinks it owns, if the number does not match the value in the
object registry it is assumed that there is an IPC message containing a
new reference in flight and this race condition was hit.
The browser side ref count is then reduced and we wait for the new deref
message. This guaruntees that an object will only be removed from the
registry if every reference we sent has been guarunteed to be unreffed.
* chore: make aliasify work on .ts files as well
* refactor: Port ipc-renderer-internal to TypeScript
* refactor: Correctly import internal ipcRenderer
* refactor: One more rename
* refactor: Fix one more lint issue
* refactor: Correctly reference ipcRendererInternal
* perf: use an internal module resolver instead of relative requires
* perf: memoize the results of getting exported Electron properties
* perf: make internal module changes consistent across sandboxed / bundled files
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_.
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
* 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.
