cb9be091aa refactor: remove potential double free when managing WebContents (#15280)
* refactor: remove -new-contents-created event

Chromium expects us to take ownership of WebContents in AddNewContents,
we should not create V8 wrapper in WebContentsCreated, otherwise we
would have WebContents being managed by 2 unique_ptr at the same time.

* refactor: make CreateAndTake take unique_ptr

10db2bce4e fix: loading of devtools extensions on startup (#13844)
* Fix loading of devtools extensions on startup

The persisted DevTools Extensions were not being loaded correctly at startup. The `addDevToolsExtension` function was not defined when it was being called. An error was being thrown and ignored, so the whole thing would fail silently. I moved the code to load the extensions to the end of the event handler, so now it works.

* fixup: remove trailing spaces to unblock CI

* fixup: add logging when the Electron Enable Logging env var is set

* Fix linter error on undefined srcDirectory

* fixup: catch exception when loading extension

* Revert "fixup: catch exception when loading extension"

This reverts commit 42c2cf95bcaab8abfc5fbecbe4365d3adfe36d5b.

14ed71fa1b fix: use render client id to track deleted render process hosts (#14520)
* fix: use render client id to track deleted render process hosts

Instead of relying on OS process id, which may not be unique
when a process is reused, we rely on the renderer client id
passed by the content layer when starting the renderer process
which is guaranteed to be unique for the lifetime of the app.

* fix: store context id as int64_t

Ensuring that it doesn't wrap easily with a large number
of context creation on some malformed web pages.

 - use enum for error types
 - minor improvements

* refactor: use more meaningful name for an arg than just "arg"

10df019075 fix: can't load module error when app is packaged
due to change in node.js(https://github.com/nodejs/node/issues/17076)
internalModuleReadFile has been renamed to internalModuleReadJSON, and
in vendor/node/lib/internal/modules/cjs/loader.js it will call
internalModuleReadJSON and result in can't read the package.json file.

ab24a1e36d feat: netLog API for dynamic logging control (#13068)
* Introduce `net.{start|stop}Logging()`

- Slight regression right now as Electron won't automatically start logging net-logs at launch, will soon be fixed
- To implement callback for async controls

* Add `net.isLogging` & optional callback param for `net.stopLogging()`

* Fix small regression on --log-net-log

--log-net-log should work again

* Error on empty file path

* Only start with valid file path

* Remove unused var

* Allow setting log file path before URLRequestContextGetter starts logging

* Add net log tests

* Remove redundant checks

* Use brightray::NetLog

* Clean up code

* Should automatically stop listening

* 🎨 Attempt to fix styles

* Only run non-null callback

* Dump file to tmpdir

* Simplify net log spec

Spawned Electron process on Linux CI can fail to launch

* Separate netLog module

* Remove net logging test from net spec

* Add tests for netLog

* Fix header guard

* Clean up code

* Add netLog.currentlyLoggingPath

* Callback with filepath

* Add test for case when only .stopLogging() is called

* Add docs

* Reintroduce error on invalid arg

* Update copyright

* Update error message

6ff111a141 perf: don't use JSON to send the result of ipcRenderer.sendSync. (#8953)
* 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
