Some recent changes to allow arm64 environments (including M1 macs) to
launch a chromium installation successfully before arm-compatible builds
were downloadable prevented the usage of PUPPETEER_EXECUTABLE_PATH in
some environments. Currently, when the platform is not darwin and the
arch is arm64, an executable cannot be specified using the environment
variable.
Generally speaking, environment variables have highest precedence for
options such as this since they depend on system configuration.
These change:
1. allow the ENV variable to always be used when defined and not
specified in LaunchOptions (and when not puppeteer-core)
2. Retain the existing behavior of assuming /usr/bin/chromium-browser on
platforms like Ubuntu (exact if-conditions preserved to avoid any
breaking changes)
3. Add some tests for this particular portion of the code.
When using a custom Firefox profile for Puppeteer the modified
preferences as present in prefs.js need to be reset once the
profile is no longer needed by Puppeteer. If not done this could
cause side-effects when the profile is used next time outside
of Puppeteer.
As ride-along fix the "--foreground" argument for Firefox will
only be used on MacOS because that's the only supported platform.
In some situations, Puppeteer is left in an invalid state because protocol errors that could have been handled by the user where just hidden from them. This patch removes some of these cases and also makes sure that unhandled promise rejections lead to a test failure in mocha.
This change adds a new `channel` parameter to `puppeteer.launch`. When specified, Puppeteer will search for the locally installed release channel of Google Chrome and use it to launch. Available values are `chrome`, `chrome-beta`, `chrome-canary`, `chrome-dev`. This parameter is mutually exclusive with `executablePath`.
We're seeing odd failures with Prettier on some CI branches; my hunch is that they are installing different versions of the package and therefore getting formatting conflicts. This PR updates them all and pins them to specific versions - something we should probably consider generally, or remove our `package-lock.json` from the gitignore.
The existing behavior is expected to be unchanged as the value defaults to true.
Adding such option would allow user to skip the initial wait.
Issue: #3630
The `Puppeteer` class had two concerns:
* connect to an existing browser
* launch a new browser
The first of those concerns is needed in all environments, but the
second is only needed in Node.
https://github.com/puppeteer/puppeteer/pull/6484 landing enabled us to
pull the `Puppeteer` class apart into two:
1. `Puppeteer` which hosts the behaviour for connecting to existing
browsers.
2. `PuppeteerNode`, which extends `Puppeteer` and also adds the ability
to launch a new browser.
This is a non-breaking change, because Node users will still get an
instance of a class with all the methods they expect, but it'll be a
`PuppeteerNode` rather than `Puppeteer`. I don't expect this to cause
people any issues.
We also now have new files that are effectively the entry points for
Puppeteer:
* `node.ts`: the main entry point for Puppeteer on Node.
* `web.ts`: the main entry point for Puppeteer on the web.
* `node-puppeteer-core.ts`: for those using puppeteer-core (which only
exists in Node, not on the web).
Launching headless with a relative `userDataDir` hangs on Windows. Fix by calling `path.resolve` (idempotent) to add an absolute path instead in `defaultArgs`.
Issues: #3453
* chore: vendor Mitt into src/common/third-party
As discussed in #6203 we need to vendor our common dependencies in so
that when we ship an ESM build all imports point to file paths and do
not rely on Node resolution (e.g. a browser does not understand `import
mitt from 'mitt'`).
* chore: enforce file extensions on imports
To make our output agnostic it should include file extensions in the
output, as per the ESM spec. It's a bit odd for Node packages but makes
it easier to publish a browser build.
* chore: remove `installAsyncStackHooks` helper
This code was written when browsers/Node didn't support errors in async
functions very well. They now do a much better job of this, so we can
lose the additonal complexity from our codebase and leave it to the host
environment :)
* lazy launcher is private
* remove async stack test
The headful one I'm permanently skipping as I don't know what the issue is and I can't debug without getting my hands on a Windows machine. If anyone has one or is able to help, that'd be great!
The other I'm deferring another month and will ping the FF folks :)
This CL migrates all the tests to TypeScript. The main benefits of this is that we start consuming our TypeScript definitions and therefore find errors in them. The act of migrating found some bugs in our definitions and now we can be sure to avoid them going forwards.
You'll notice the addition of some `TODO`s in the code; I didn't want this CL to get any bigger than it already is but I intend to follow those up once this lands. It's mostly figuring out how to extend the `expect` types with our `toBeGolden` helpers and some other slight confusions with types that the tests exposed.
