Add recommended automation preferences to profile
setup when launching Firefox. This profile can be overridden
by using the `userDataDir` launch option, or individual prefs
can be overwritten with the `extraPrefsFirefox` option.
The preferences have been reviewed by peers at Mozilla
over at https://bugzilla.mozilla.org/show_bug.cgi?id=1596888

* feat: Set which browser to launch via PUPPETEER_PRODUCT
This change introduces a PUPPETEER_PRODUCT environment
variable as a first step toward using Puppeteer with
many different browsers. Setting PUPPETEER_PRODUCT=firefox, for
example, enables Firefox-specific Launcher settings.
The state is also exposed as `puppeteer.product` in the API
to support adding other product-specific behaviour as needed.
The bulk of the change is a refactoring in Launcher
to decouple generic browser start-up from product-specific
configuration.
Respecting the puppeteer-core restriction for PUPPETEER_
environment variables, lazily instantiate the Launcher
based on a `product` Puppeteer.launch option, if available.
* test: Distinguish Juggler unit tests from Firefox
The funit script is renamed to fjunit (j for Juggler, which is
used only by the experimental puppeteer-firefox package.
In contrast, the funit script now refers to running Puppeteer
unit tests against the main puppeteer package with Firefox.
To do so with Firefox Nightly, run:
`BINARY=path/to/firefox npm run funit`
A number of changes in this patch make it easier to run
Puppeteer unit tests in Mozilla's CI.
Node.js v6 was end-of-life'd in April, 2019, with AWS Lambda prohibiting updaets to the Node.js v6 runtime since June 30, 2019.
This makes it quite safe for us to remove the Node 6 support from the repository.
As someone who's new to the project, I read the contributing guide and spotted some things that confused me. Hopefully this patch helps to reduces the confusion for others!
We'd like to pass an abortion signal inside Helper.waitForEvent in order to interrupt it when browser/page closes. Several approaches have been considered:
1. Pass CDPSession instance as a another parameter to the helper method and listen to Disconnected event on it. It would introduce undesired dependency on the session object.
2. Listen to the CDPSession closure at the call sites (e.g. waitForRequest) and pass an abortion promise which would be fulfilled when such event is fired. The listeners would have to be removed from the session on successful completion of waitForEvent so we'd have to pass some kind of DisposablePromise which would be disposed during cleanup. Such parameter looked somewhat hairy.
3. Create DisconnectPromise on CDPSession. One potential risk with that is all chained promises would hang around until the event is fired which might inadvertently cause memory leaks. On the other hand, adding such promise to Promise.race will remove dependency as soon as the race is finished. So this is the approach we're taking with one tweak: the promise is created locally inside Page.
Ideally the disconnectPromise would throw when the session is closed but it may lead to uncaught promise errors if all chained promises are resolved, to avoid that the promise is resolved with an Error and Helper.waitForEvent throws it later.
Fix#4733
Our magical node6 transpiler can't handle object spreads :(
Drive-by: use "includes" instead of "startsWith" for devtools URL
since I remember that it used to be "chrome-devtools://", and somehow
I saw it as "devtools://" somewhere.
This roll includes:
- https://crrev.com/681997 - Turn on default SiteInstance by default.
The SiteInstance by default was breaking "devtools: true" option, so
there's a new feature we disable now by default.
This keeps pressuring us towards OOPIF support since that's an
inevitable future.
