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.
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.
This bug continues elusive. The latest crash logs show us that, somehow, 1
script is being resolved from 2 transfer objects. This doesn't seem possible,
so I'm adding more properties to log the state of both transfers to try and
figure out how this is happening.
