Adds a not-documented "wpt" mode to --dump which outputs a formatted
report.cases.
This is meant to make working on a single WPT test case easier, particularly
with some coding tool. Claude recommended this output for its own use.
Instead of telling claude to start the browser in serve mode, then run the
wptrunner, and merge the two outputs (and then stop the server), you can do:
zig build run -- fetch --dump wpt "http://localhost:8000/dom/nodes/CharacterData-appendChild.html"
(you still need the wpt server up)
I'm not sure what the correct behavior is, but this fixes a WPT crash:

The issue is iframe-specific as, with an iframe, you document.write can be
called during parsing when there's no document._current_script (because it's
being executed from the parent).
Follow up to https://github.com/lightpanda-io/browser/pull/1646 applies the
same change to XHR URLs.
Following specs, ignores unknown/invalid parameters of the Content-Type when
parsing the MIME (rather than rejecting the entire header).
I think this code comes from some serialization tweak from when everything was
an std.Uri and by switch to [:0]const u8 everywhere not only was the tweak
unecessary, it was also wrong - possibly resulting in the generation of
invalid JSON.
Was looking at, what I thought was a related issue, and started to extract this
code to re-use it (in DataURIs). Realized it could be written without the
intermediate allocation. Then I realized the dataURI issue is something else,
but wanted to keep this improvement.
After looking at a handful of websites, the # of Text and Commend nodes
that are small (<= 12 bytes) is _really_ high. Ranging from 85% to 98%. I
thought that was high, but a lot of it is indentation or a sentence that's
broken down into multiple nodes, eg:
<div><b>sale!</b> <span class=price>$1.99</span> buy now<div>
So what looks like 1 sentence to us, is actually 3 text nodes.
On a typical website, we should see thousands of fewer allocations in the
page arena for the text in text nodes.
Most importantly, this allows the Selector.List to be self-contained with
an arena from the ArenaPool. Selector.List can be both relatively large
and relatively common, so moving it off the page.arena is a nice win.
Also applied this to ChildNodes, which is much smaller but could also be
called often.
I was initially going to hook into the v8::Object's internal fields to store
the referencing v8::Object. So the v8::Object representing the Iterator
would store the v8::Object representing the NodeList inside of its internal
field - which the GC would trace/detect/respect. And that is probably the
fastest and most v8-ish solution, but I couldn't come up with an elegant
solution. The best I had was having a "afterCreate" callback which passed
the v8 object (this is similar to the old postAttach callback we had, but
used for a different purpose). However, since "acquireRef" was recently
added to events, re-using that was much simpler and worked well.
Shutdown on MacOS doesn't work properly. The process appears to shutdown, but
will continue to run in the background. It can run infinitely if it's stuck in
a JS loop. To help it along, Client.stop now force-terminates the isolate.
I also don't think shutdown is working as intended on Linux, but the problem
seems less serious there. On Linux, it appears to properly kill the process
(which is the important thing), but I don't think it necessarily does a clean
shutdown.
Since we already rely on github for builds, this removes a point of failure.
Also curl.se consistently fails from a VPS machine for me - not sure if
they're blocking IP ranges, but it works fine on github.
