Before that it actually didn't install all needed dependencies and failed after that when starting the compiler suite. WebKit also installs dependencies with apt, so it should be fine to install them on OS level.
- to read post data of requests, we have to read stream
- to restore the stream later on, we have to rewind it back
- however, if the stream is large enough, it cannot be rewound back
This patch starts cloning post data streams if possible to avoid
back-rewinding them later on.

After this roll, we no longer require our custom `onFrameLocationChanged` instrumentation
since gecko now fixed the `NOTIFY_LOCATION` behavior so that it works
for same-document navigations inside iframes.
browser(firefox): properly initialize debugging pipe on windows
Firefox on Windows has 2 launch modes:
- default: a special "launcher process" is used to start browser as a
sub-process
- non-default: browser process starts right away
Firefox has a logic to detect how successful was the use of the
launcher process to do self-recovery when things go wrong. Namely:
- when attempting to use launcher process, firefox records a timestamp
of the attempt beginning
- once the launcher process successfully launches browser sub-process,
firefox records another timestamp of the completion
On a new launch, firefox checks what timestamps are present. If there's
a timestamp that signifies start of launcher process, but no successful
timestamp, it decides that last "launcher process" use was not
successful and falls back to launching browser right away.
When launching 2 firefox processes right away, the first process
uses attempts to use launcher process and records the first timestamp.
At the same time, the second instance sees the first timestamp and
doesn't see the second timestamp, and falls back to launching browser
right away. Our debugging pipe code, however, does not support
non-launcher-process code path.
This patch adds support for remote debugging pipe in case of
non-launcher-process startup.
Drive-by:
- disable crashreporter altogether
- remove stray dcheck that breaks firefox debug compilation
- disable compilation of firefox update agent
- do not use WIN32_DISTRIB flag unless doing full builds since
it kills incremental compilation

**Preamble**
1. We're trying to setup a windows-based github self-hosted runner in the
playwright-internal repo.
1. Commands on Windows are mandated to have total arguments length
less then 32767 characters.
1. On windows, github self-hosted runner framework puts repository
checkout at `c:\w\playwright-internal\playwright-internal`
1. Our scripts create a checkout at
`c:\w\playwright-internal\playwright-internal\browser_patches\firefox\checkout`
1. One of the scripts in Firefox buildsystem tries to execute a command,
passing lots of absolute paths to various webidl's
1. The command fails due to restriction in (2)
**Problem**
Firefox build fails since checkout is deeply nested and hits max arg
size on windows.
**Solution**
This patch introduces a new variable `FF_CHECKOUT_PATH` that is
respected by all browser-related scripts. This way we'll be able
to checkout firefox to `c:\firefox` and avoid hitting long arguments
limit.
The `$PROGRAMFILES` variable is defined per the bitness of the
application: 32-bit shells get `C:\Program Files (x86)`, whereas
64-bit shells get `C:\Program Files`.
Visual Studio, however, has only 32-bit build and is always located in
the `C:\Program Files (x86)` folder.
This patch fixes `//browser_patches/firefox/build.sh` on 64-bit windows
shell.
browser(firefox): ensure detachedFromTarget is always sent
LinkedBrowser can throw when removing listeners in PageTarget.dispose,
and that prevents BrowserHandler from sending Browser.detachedFromTarget.
Using a try-catch seems good enough.
Currently, browser.version() returns `83.0`, whereas launching firefox
with `--version` flag returns `83.0b3`. This patch alings protocol's
`Browser.version()` with flag output.
Somehow, we get WebProgress state changes when worker is loaded
with a blob url. This messes up frame navigation detection.
Luckily, it's easy to filter out non-document state changes.
As Joel noticed recently, MessageManager in firefox doesn't guarantee
message delivery if the opposite end hasn't been initialized yet. In
this case, message will be silently dropped on the ground.
To fix this, we establish a handshake in SimpleChannel to make sure that
both ends are initialized, end buffer outgoing messages until this
happens.
Drive-by: serialize dialog events to only deliver *after* the
`Page.ready` protocol event. Otherwise, we deliver dialog events to the
unreported page.
We try to avoid closing firefox too early, fearing that this
might terminate clean shutdown sequence.
Usually we assume that `Browser.enable` is called before `Browser.close`
- however, this is not the case in certain tests. So we have to
ensure browser initialization in `Browser.close` as well.
In my local tests, this fixes the Firefox Pipe problem: it looks like
we were closing browser too quickly.
It looks like terminating browser when search service or addon manager is
not fully initialized results in a broken shutdown sequence. As of
today, this results in multiple errors in the browser STDERR. In future,
this might also result in browser stalling instead of terminating.
This starts awaiting search and addon manager termination.
References #3995
Using WebProgressListener events works in all cases. Currently
used `pageshow` event will stop being emitted in future when loading
was stopped with `window.stop()` api.
References #3995
This patch:
- moves `SimpleChannel` to synchronously dispatch buffered commands
instead of a `await Promise.resolve()` hack
- moves dialog & screencast handling from `PageHandler` to
`TargetManager`. This leaves `PageHandler` to be concerned solely about
protocol.
- removes `attach` and `detach` methods for worker channels: since
channels are buffering messages until the namespace registers, there's
no chance to loose any events.
- slightly simplifies `PageNetwork` class: it's lifetime is now
identical to the lifetime of the associated `PageTarget`, so a lot can
be simplified later on.
References #3995
In the current tip-of-tree Firefox, document channel is enabled by
default, so we have to enable it in order to roll further.
This patch:
1. Removes content disposition sniffing from content process since it
crashes renderer with document channel.
2. Merges all page-related handlers in a single `PageHandler` and
serializes network events wrt the `Page.frameAttached` event.
The serialization mentioned in (2) is necessary: frame attachment is
reported from the content process, and network events are reported from
the browsers process. This is an inherent race, that becomes exposed by
the document channel.
On a side note, (2) makes it possible to synchronously report all
buffered events in `SimpleChannel` (cc offline discussion with @dgozman
that highlighted an unsighty approach that we currently employ there: reporting
events in a subsequent microtask.)
References #3995
This patch:
1. Changes `SimpleChannel` to buffer messages to the namespace that
hasn't been registered yet. This allows us to create `SimpleChannel`
per target on the browser side right away.
2. Removes multisession support. Now there's only one `PageAgent` in the
content process, which talks to a single `PageHandler` on the browser
side. Both ends can be created as-soon-as-needed; thanks to
`SimpleChannel` bufferring, no messages will be lost and all messages
will be delivered in proper order. (This is currently the reason why
build 1178 flakes on windows).
3. Straightens up the target reporting. Targets are reported as soon
as they appear on the browser side.
**NOTE:** this doesn't yet remove sessions from protocol.
References #3995
We currently might double-attach to the target in `BrowserHandler` since we iterate over all targets, and then subscribe to the additional event when target is getting initialized.
This patch fixes this race condition and should unblock the roll to r1177.
References #3995
As of today, we create `PageTarget` instances whenever we get a
sync IPC from the content process. This, however, breaks an invariant
that `browserContext.pages` always has all pages (and *browsing contexts* - not to be confused with *browser contexts*), associated with browser context. This invariant will be especially important when we move
user agent emulation to browser-side.
This patch makes `PageTarget` lifecycle symmetrical:
- `PageTarget` instance is created when tab is opened
- `PageTarget` is destroyed when tab is crashed or closed
This should also fix a bunch of race conditions with persistent mode, since sometimes we arrive to the window after its
initialization.
Drive-by: straighten viewport management and put a nice descriptive comment.
Juggler code had a bug where we subscribed to window and tab
events, but did not iterate collections of current windows and tabs.
As a result, we were sometimes failing to set viewport size for the
initial window, and implemented an artificial promise to workaround
the problem.
This patch:
- starts calling `onOpenWindow` and `onOpenTabListener` callbacks
for *all* windows and tabs - current and future, eliminating the
race condition.
This worked too well and we started overriding window sizes that
were set by users with `window.open(url, 'width=300;height=400')` (we
have a test for this). To fix this, we now plumb `CHROME_WITH_SIZE`
flag from appWindow and override viewport iff this flag is not set.
After this patch, we will use the `onTabOpened` event to move user
agent emulation to the browser-side.
References #3995
BrowsingContextIDs are consistent across the processes, so we can use
them to target frames in both browser and content processes. This will
aid browser-side navigation.
As a nice side-effect, we can drop a round-trip to the content process
for every `requestWillBeSent` event since we *almost* always can
attribute all network events to the proper parent frames.
I say "almost", because we in fact **fail** to correctly attribute requests
from workers that are instantiated by subframes. This, however, is
not working in Chromium ATM, so I consider this to be a minor regression
that is worth the simplification.
browser(firefox): fix automatic http->https redirect
Sometimes, Firefox does an automatic http->https redirect without hitting
the network (e.g. for http://wikipedia.org). In this case, the http request
is very strange:
- it does not actually hit the network;
- it is never intercepted;
- we cannot access its response because there was no actual response.
So, we had a bug where:
- redirects inherited the original request's listener;
- that listener was throwing an error.
This lead to the error in the listeners onDataAvailable call chain,
and original listener that renders the response was never called,
resulting in an empty page.
This change:
- ignores the original request that did not hit the network;
- does not inherit the listener;
- adds try/catch around problematic calls.
Firefox will sometimes send multiple requests with the same http channel id. When a frame is loaded, the favicon is requested in the parent frame, but with the same channel id. This can cause the document request to report the wrong frame, causing the test 'should capture iframe navigation request' to fail. It fails consistently on my computer.
This patch adds the content policy type into the http channelId to better distinguish requests. Maybe there is something better we can do? It looks like we use channelId has request ids, so there might be more bugs with these favicon requests in playwright?
Otherwise if required version is not installed the build fails with a cryptic message like
`error: toolchain '1.45.0-x86_64-unknown-linux-gnu' does not support components`
`MediaFeatureValuesChanged` is what their devtools code uses to update the styles. I tried using their code directly, but it doesn't play nicely with navigations so I decided to stick with ours.
Firefox buildchain does not fixate `rust` and `cbindgen` versions,
so we want to fixate them on our end.
A table with matching rust version for every firefox version can
be found at [Rust Update Policy for Firefox](https://wiki.mozilla.org/Rust_Update_Policy_for_Firefox).
Additionally, there are checks in `mozbuild` for the minimum
rust version and minimum `cbindgen` version.
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`
