This is an alternative approach to #3698 that was setting up a custom
mapping between chromium revisions and our mirrored builds. For example, we were
taking chromium `792639` and re-packaging it to our CDN as Chromium 1000.
One big downside of this opaque mapping was inability to quickly
understand which Chromium is mirrored to CDN.
To solve this, this patch starts treating browser revision as a fractional number,
with and integer part being a chromium revision, and fractional
part being our build number. For example, we can generate builds `792639`, `792639.1`,
`792639.2` etc, all of which will pick Chromium `792639` and re-package it to our CDN.
In the Playwright code itself, there are a handful of places that treat
browser revision as integer, exclusively to compare revision with some particular
revision numbers. This code would still work as-is, but I changed these places
to use `parseFloat` instead of `parseInt` for correctness.
We used to do fetch() to decode the file buffer. However, this is
blocked by strict CSP policy. Instead, we can use explicit
string -> bytes conversion, and trade performance for CSP compliance.
As discussed offline, our testing scenarios assume running trusted
web content - so this warning is just a noise for this usecases.
When it comes to dealing with untrusted web content though, automation
authors need to make sure to not launch browsers under root in the first
place.
This is a large rework of selectors:
- Each BrowserContext now has a separate Selectors instance that has its own registrations.
Most of them share a single sharedSelectors instance, but contexts created for a connected
browser have their own instance.
- Connected browser now gets a RemoteBrowser object that encapsulates Selectors and Browser.
This Selectors object is registered with the api selectors.
- Public selectors.register api iterates over all registered Selectors channels
and registers in each of them.
- createSelector testing method migrated to ElementHandle._createSelectorForTest.
Sometimes I see "cannot call emit on the undefined" error on the bots.
This change adds some more logging, so we could potentially identify where
the issue comes from.
This introduces basic tracing enabled in our tests.
What is captured:
- network resources;
- snapshots at the start of most actions;
- snapshot after the test failure.
How this integrates with test runner:
- context fixture calls private method context._initSnapshotter() and uses Tracer to trace all events;
- all tests share a single test-results/trace-storage directory to store blobs;
- each test has its own trace file.
- npm run show-trace opens a bare-minimum trace viewer that renders snapshots.
Root index.js is only used for local development, so
assuming dev mode there is fine. This way we do not have
to worry about calling setUnderTest early enough.
One by one seems like a resonable minimum size for clicking.
It is not surprising to see a 1x1 native accessible control
that is covered by a custom control that handles input instead.
Due to wrong type usage, we ignored the origin while granting permissions.
Switching to generated types revealed this issue. We should follow up
with switching all dispatchers to the generated types.
This changes the behavior of slowmo to slow down user actions instead of every protocol command. This makes slowmo a lot more predictable. Without this, there is no way to set slowmo to a good value without incurring a huge delay at the start of your test when it sets things up.
This touches:
- noDefaultViewport;
- ignoreAllDefaultArgs;
- env;
- validateXYZ logic that was copying objects - we do not need that anymore;
- shuffles some converters closer to their usage.
This method waits for visible, hidden, stable or enabled state,
similar to the actionability checks performed before actions.
This gives a bit more control to the user. Some examples:
- Allows to wait for something to be stable before taking a screenshot.
- Allows to wait for the element to be hidden/detached after a specific action.
- Never write to console on the server side - we use stdout for
communication. This includes logPolitely and deprecate.
- Pass undefined instead of null in some BrowserContext methods.
- Use explicit _setFileChooserIntercepted instead of on/off magic.
This migrates Firefox to the protocol-based proxy implementation.
Benefits:
- supports secure web proxies (already supported by Chromium)
- unlocks support for SOCKS proxies with authentication
This starts downloading newer Chromium archives from our CDN, but
retains old endpoint for older Chromium revisions.
This backwards compatibility might help later on to implement
a browser bisecting tool.

Everywhere in our api, possibly missing properties are nullable.
However, to make things easier for everyone, we just default to an
empty url instead, so that users do not have to null-check it.
Make sure executable exists before launching it. If it doesn't and
we were launched without custom executable path, print a helpful
instruction to run `npm i playwright` and get browsers downloaded.
Note: there's already a test that makes sure bad executable paths
are treated fairly: 9132d23b2b/test/launcher.jest.js (L54-L59)
This doesn't test missing default browser installation which I think is
fine.
Fixes#3161
WebKit WPE assumes `libglesv2.so` is available on the host system
and uses `dlopen` to open it.
This patch starts using `ldconfig -p` to check if the library
exists on the system.

Renderer-based method DOM.getContentQuads and DOM.getBoxModel return
coordinates relative to the local root's viewport, but we need them relative
to the root viewport.
This adds one more protocol message __dispose__
to dispose a scope and all child objects.
Now, client side does not need a notion of scope anymore -
it just disposes the whole object subtree upon __dispose__.
Server, on the other hand, marks some objects as scopes
and disposes them manually, also asserting that all parents
are proper scopes.
This makes it easier to reason about our packages.
The only difference is what each package downloads.
When the browser is not downloaded, it will fail to launch.
Each browser gets a 'download' attribute in the browser.json file.
The original plan was to rnu some checks against libc version the
binary is compiled with, but these turn out to be a little complicated:
parsing out libc version from both static binary and host system
requires text processing, and it's hard to make sure it works reliably
across distributions.
Instead, let's start with a very particular check against running
Firefox on Ubuntu 16.04.

Before typing/pressing, we focus the target element. WebKit
sometimes selects the value in this case. To unify the behavior
between the browsers we behave similar to human:
- when the input is already focused, we just type;
- when the input is not focused, we focus it, move caret
to the start (like if user clicked at the start to focus the input)
and then type.
Note this only affects inputs with non-empty value.
This establishes a single naming for all our blobs with browser
builds that we upload to CDN: `<browser-name>-<os-version>`
- `<browser-name>` is either `firefox` or `webkit`.
- `os-version` is the OS that was used to produce the build.

This patch:
- specializes "linux" scripts into "Ubuntu 18.04" scripts
- renames all future linux blobs on CDN:
* `firefox-linux.zip => firefox-ubuntu-18.04.zip`
* `minibrowser-gtk.zip => minibrowser-gtk-ubuntu-18.04.zip`
* `minibrowser-wpe.zip => minibrowser-wpe-ubuntu-18.04.zip`
* `minibrowser-gtk-wpe.zip => minibrowser-gtk-wpe-ubuntu-18.04.zip`
- updates downloader to deal with the new names
