This commit initializes the LibVideo library and implements parsing
basic Matroska container files. Currently, it will only parse audio
and video tracks.
This changes the RequestClient::start_request() method to take a URL
object instead of a URL string as argument. All callers of the method
already had a URL object anyway, and start_request() in turn parses the
URL string back into a URL object. This removes this unnecessary
conversion.
After marking a thread for death we might end up finalizing the thread
while it still has code to run, e.g. via:
Thread::block -> Thread::dispatch_one_pending_signal
-> Thread::dispatch_signal -> Process::terminate_due_to_signal
-> Process::die -> Process::kill_all_threads -> Thread::set_should_die
This marks the thread for death. It isn't destroyed at this point
though.
The scheduler then gets invoked via:
Thread::block -> Thread::relock_process
At that point we still have a registered blocker on the stack frame
which belongs to Thread::block. Thread::relock_process drops the
critical section which allows the scheduler to run.
When the thread is then scheduled out the scheduler sets the thread
state to Thread::Dying which allows the finalizer to destroy the Thread
object and its associated resources including the kernel stack.
This probably also affects objects other than blockers which rely
on their destructor to be run, however the problem was most noticible
because blockers are allocated on the stack of the dying thread and
cause an access violation when another thread touches the blocker
which belonged to the now-dead thread.
Fixes#7823.
This adds test pages for border-radius, CSS custom properties and
flexboxes to the default page in the Browser.
I used those files to develop said features and they can be of use
when debugging in the future or just to showcase those features.
By moving the logic to determine what window areas (shadow, frame,
content) into WindowFrame::opaque/transparent_render_rects we can
simplify the occlusion calculation and properly handle more
arbitrary opaque/transparent areas.
This also solves the problem where we would render the entire
window frame as transparency only because the frame had a window
shadow.
I have no idea *why*, but this stopped working suddenly:
return { { .code_point = '-', .is_character_class = false } };
Fails with:
error: could not convert ‘{{'-', false}}’ from
‘<brace-enclosed initializer list>’ to
‘AK::Optional<regex::CharClassRangeElement>
Might be related to 66f15c2 somehow, going one past that commit makes
the build work again, however reverting the commit doesn't. Not sure
what's up with that.
Consider this patch a band-aid until we can find the reason and an
actual fix...
Compiler version:

This is a fairly small change; removed the statement "Pointer and
reference types in C++ code" as it does not provide any additional
knowledge that contributors are or will be aware of after further
reading into the "Pointers and References" section. It seems
unnecessary and redundant given the sentence adjacent to it.
This patch removes some FIXMEs from the StyleResolver, specifically
adding the proper float-parsing to the flex: shorthand. The
functionality was already there it just didn't get plumbed in before.
The line history is unavailable if the alternate screen buffer is
currently enabled. However, since TerminalWidget uses the history size
to offset its line numbers when rendering, it will try to render
inaccessible lines once the history is not empty anymore.
When attempting to write to a socket that is not connected or - for
connection-less protocols - doesn't have a peer address set we should
return EPIPE instead of blocking the thread.
Previously, AK::Function would accept _any_ callable type, and try to
call it when called, first with the given set of arguments, then with
zero arguments, and if all of those failed, it would simply not call the
function and **return a value-constructed Out type**.
This lead to many, many, many hard to debug situations when someone
forgot a `const` in their lambda argument types, and many cases of
people taking zero arguments in their lambdas to ignore them.
This commit reworks the Function interface to not include any such
surprising behaviour, if your function instance is not callable with
the declared argument set of the Function, it can simply not be
assigned to that Function instance, end of story.
According to the definition at https://sqlite.org/lang_expr.html, SQL
expressions could be infinitely deep. For practicality, SQLite enforces
a maxiumum expression tree depth of 1000. Apply the same limit in
LibSQL to avoid stack overflow in the expression parser.
