Bring the names of various boxes closer to spec language. This should
hopefully make things easier to understand and hack on. :^)
Some notable changes:
- LayoutNode -> Layout::Node
- LayoutBox -> Layout::Box
- LayoutBlock -> Layout::BlockBox
- LayoutReplaced -> Layout::ReplacedBox
- LayoutDocument -> Layout::InitialContainingBlockBox
- LayoutText -> Layout::TextNode
- LayoutInline -> Layout::InlineNode
Note that this is not strictly a "box tree" as we also hang inline/text
nodes in the same tree, and they don't generate boxes. (Instead, they
contribute line box fragments to their containing block!)
This makes most operations thread safe, especially so that they
can safely be used in the Kernel. This includes obtaining a strong
reference from a weak reference, which now requires an explicit
call to WeakPtr::strong_ref(). Another major change is that
Weakable::make_weak_ref() may require the explicit target type.
Previously we used reinterpret_cast in WeakPtr, assuming that it
can be properly converted. But WeakPtr does not necessarily have
the knowledge to be able to do this. Instead, we now ask the class
itself to deliver a WeakPtr to the type that we want.
Also, WeakLink is no longer specific to a target type. The reason
for this is that we want to be able to safely convert e.g. WeakPtr<T>
to WeakPtr<U>, and before this we just reinterpret_cast the internal
WeakLink<T> to WeakLink<U>, which is a bold assumption that it would
actually produce the correct code. Instead, WeakLink now operates
on just a raw pointer and we only make those constructors/operators
available if we can verify that it can be safely cast.
In order to guarantee thread safety, we now use the least significant
bit in the pointer for locking purposes. This also means that only
properly aligned pointers can be used.
...instead of maybe bitmap + a single mime type and its corresponding data.
This allows drag&drop operations to hold multiple different kinds of
data, and the views/applications to choose between those.
For instance, Spreadsheet can keep the structure of the dragged cells,
and still provide text-only data to be passed to different unrelated editors.
Now we (almost) verify all the sites we browse.
Certificate verification failures should not be unexpected, as the
existing CA certificates are likely not complete.
This API is only used for HttpRequest, but replicated in GeminiRequest
without an actual user, so remove it and construct the job like the rest
of the protocols.
The configuration key [DNS] Nameserver has been renamed to Nameservers
and accepts a comma-separated list of nameserver addresses, which will
be queried in the given order until a response has been received.
The new default value is still Cloudflare's 1.1.1.1 as well as their
secondary DNS server 1.0.0.1.
did_timeout is a bool& parameter of lookup() that used to be set when
the UDP connection timed out, but this behaviour was broken in e335d73.
I replaced it with a more useful 'did_get_response' parameter that is
being set after the UDP socket connected, sent its request and got a
response - it might still be bogus data but we know the communication
was successful.
This reverts my previous commit in WebServer and fixes the whole issue
in a much better way. Instead of having the MIME type guesser take a
URL (which we don't actually have in the WebServer at that point),
just take a path as a StringView.
Also, make use of the case-insensitive StringView::ends_with() :^)
When you GET a directory with an index.html file, we were using the
mime type guessing logic from LibCore on the "/" filename, which gave
us "text/plain". Force the mime type to "text/html" in these cases
so browsers actually interpret it as HTML. :^)
In the future all (normal) output should be written by any of the
following functions:
out (currently called new_out)
outln
dbg (currently called new_dbg)
dbgln
warn (currently called new_warn)
warnln
However, there are still a ton of uses of the old out/warn/dbg in the
code base so the new functions are called new_out/new_warn/new_dbg. I am
going to rename them as soon as all the other usages are gone (this
might take a while.)
I also added raw_out/raw_dbg/raw_warn which don't do any escaping,
this should be useful if no formatting is required and if the input
contains tons of curly braces. (I am not entirely sure if this function
will stay, but I am adding it for now.)
If we're sharing buffers, we only want to share trivial structures
as anything else could potentially share internal pointers, which
most likely is going to cause problems due to different address
spaces.
Fix the GUI::SystemTheme structure, which was not trivial, which
is now caught at compile time.
Fixes#3650
I could not test these changes because I could not get my telnet client
(on Linux) to connect to the telnet server running in Serenity.
I tried the follwing:
# Serenity
su
TelnetServer
# Linux
telnet localhost 8823
The server then immediatelly closes the connection:
Connection closed by foreign host.
In the debug logs the following message appears:
[NetworkTask(5:5)]: handle_tcp: unexpected flags in FinWait2 state
[NetworkTask(5:5)]: handle_tcp: unexpected flags in Closed state
[NetworkTask(5:5)]: handle_tcp: unexpected flags in Closed state
This seems to be an unrelated bug in the TCP implementation.
There is a window between windows disappearing (e.g. closing or crashes)
and the Taskbar process being notified. So it is entirely possible that
it may call SetWindowTaskbarRect() for a window and/or client id that no
longer exists. As the Taskbar process does not own these windows, this
should not be treated as a misbehaving application request. Instead, just
silently ignore the request. The Taskbar will be notified shortly after
that the window no longer exist and remove it from its list.
Fixes#3494
Instead of everyone overriding save_to() and set_property() and doing
a pretty asymmetric job of implementing the various properties, let's
add a bit of structure here.
Object properties are now represented by a Core::Property. Properties
are registered with a getter and setter (optional) in constructors.
I've added some convenience macros for creating and registering
properties, but this does still feel a bit bulky. We'll have to
iterate on this and see where it goes.
This patch introduces IPC::Connection which becomes the new base class
of ClientConnection and ServerConnection. Most of the functionality
has been hoisted up to the base class since almost all of it is useful
on both sides.
This gives us the ability to send synchronous messages in both
directions, which is needed for the WebContent server process.
Unlike other servers, WebContent does not mind blocking on a response
from its client.
When invalidating the frame we need to properly flag that so that
we trigger rendering the frame, even if "all" was flagged as being
invalidated. Otherwise it will only get rendered if anything else
happens to trigger it (such as focus change).
Fixes#3427
Do not fill the backing store mismatch area with the solid window
color if the window is transparent. This caused some minor flicker
when such a window is e.g. snapped to the left/right or maximized.
