This patch changes cursor type from caret to black box for both Hex and
Text modes, because right now the way how blinking caret looks like is
more closer to "insert" mode in similar editors, whereas the real
behavior of this cursor is more of a "replace" mode seen in similar
editors like GHex.
This stopped being called for anything without a navigable container
after 76a97d8, due to the early return. This broke SVG <use> elements
that reference elements defined later in the document.
This should allow us to eventually properly saturate high-bandwidth
network links when using TCP, once other nonoptimal parts of our
network stack are improved.
Instead of lying and claiming we always have space left in our receive
buffer, actually report the available space.
While this doesn't really affect network-bound workloads, it makes a
world of difference in cpu/disk-bound ones, like git clones. Resulting
in a considerable speed-up, and in some cases making them work at all.
(instead of the sender side hanging up the connection due to timeouts)
Previously we would incorrectly handle the (somewhat uncommon) case of
binding and then separately connecting a tcp socket to a server, as we
would register the socket during the manual bind(2) in the sockets by
tuple table, but our effective tuple would then change as the result of
the connect updating our target peer address. This would result in the
the entry not being removed from the table on destruction, which could
lead to a UAF.
We now make sure to update the table entry if needed during connects.
POSIX (rightfully so) specifies that the sendto address argument is
ignored in connection-oriented protocols.
The TCPSocket also assumed the peer address may not change post-connect
and would trigger a UAF in sockets_by_tuple() when it did.
This also removes the code for displaying `gemini://` documents. We
currently don't load documents from that protocol anyway - we hit
`attempt_to_create_a_non_fetch_scheme_document()` in `Navigable.cpp`
which is just a stub. It looks like we should be handling those
separately from regular "fetch" documents, so that's a task for a
future person.
(Apologies for bad commit title, it's hard to explain in such a short
space!)
We're going to need to call this for producing markdown and gemini
documents, both of which need a Document and Realm to fetch the entire
response body, so that they can then generate their HTML. So this
commit modifies `create_document_for_inline_content()` to take a lambda
instead of a fixed HTML string, to support these uses.
Also, we always return a nonnull pointer, so make that the return type.
This is a move and change in the same commit, (Sorry!) but all the
changes are to the function signature and step 6.
There's an unfortunate hack here. We have to load the media file's data
before we call `HTML::HTMLParser::the_end()` with our generated
document, otherwise the media element (`<img>`/`<audio>`/`<video>`)
never loads and that blocks the document's load event. The previous code
path also did this, which is perhaps why the bug was never noticed.
This is a little awkward: The spec requires when loading media documents
or ones that don't have a DOM, that we "act as if the user agent had
stopped parsing document" which means following this algorithm. Only a
few steps require an HTMLParser, but those that do, involve reaching
into its internals. The simplest solution I could think of (other than
duplicating this fairly hefty function) is making it static and taking
a Document and optional HTMLParser as parameters.
So far, we always call make_active() before update_readiness
(Complete), but this will soon not be the case once we implement the
spec document-loading algorithms.

This function is currently very ad-hoc. This commit adds comments which
are almost entirely FIXMEs, so that we can then start filling in the
details one step at a time.
There's no mention in the spec of this being optional, all the places
that call it always pass a NavigationParams directly, and we're
VERIFYing that it's got a value too!
Before this change, we would only cache and reuse Gfx::ScaledFont
instances for downloaded CSS fonts.
By moving it into Gfx::VectorFont, we get caching for all vector fonts,
including local system TTFs etc.
This avoids a *lot* of style invalidations in LibWeb, since we now vend
the same Gfx::Font pointer for the same font when used repeatedly.
We don't need to skip whitespace at the top level because that's already
done before we're called. But we do still have to skip it inside the
`add()` function
