There are use cases of webview where the container holding the webview is not
actually destroyed first, instead just webview gets removed from DOM, in such
situations the browser process map is not updated accordingly and holds reference
to stale guest contents, and any window operations like scroll, resize or keyboard
events that has to chain through browser embedder will lead to UAF crash.

* fix: disable remote host nodeIntegration warning for localhost
In warnAboutNodeWithRemoteContent(), add a check to see if the hostname
is "localhost" and prevent the warning message if it is.
* fix: disable loading insecure resources warning for localhost
In warnAboutInsecureResources(), filter out resources from localhost
since they are most likely not a threat.
* test: add tests for ignoring security warnings when using localhost
Add tests for ignoring warning messages for the following scenarios:
1. node integration with remote content from localhost
2. loading insecure resources from localhost
* test: fix insecure resource test
* test: pass nodeIntegration with remote test on did-finish-load
* test: maybe fix node integration test (error w/ conv circular struct)
* test: update test description
* test: use "load" event to check when nodeIntegration test has finished
Instead of relying on the "did-finish-load" event, which may result in
a race condition, add an "onload" handler that logs "loaded" to the
console. This will execute _after_ the nodeIntegration check, so it
can be safely used as a signal to indicate that the test is done.
* test: rename base-page-security-load-message.html
* fix: ignore enabled remote module warning for localhost
* refactor: add isLocalhost()
* 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
* fix: add boringssl backport to support node upgrade
* fix: Update node_includes.h, add DCHECK macros
* fix: Update node Debug Options parser usage
* fix: Fix asar setup
* fix: using v8Util in isolated context
* fix: make "process" available in preload scripts
* fix: use proper options parser and remove setting of _breakFirstLine
_breakFirstLine was being set on the process, but that has changed in node 12 and so is no longer needed. Node will handle it properly when --inspect-brk is provided
* chore: update node dep sha
* fix: process.binding => _linkedBinding in sandboxed isolated preload
* fix: make original-fs work with streams
* build: override node module version
* fix: use _linkedBinding in content_script/init.js
* chore: update node ref in DEPS
* build: node_module_version should be 73
* 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.
