Previously RS handled all the requests in an event loop, leading to
issues with connections being started in the middle of other connections
being started (and potentially blowing up the stack), ultimately causing
requests to be delayed because of other requests.
This commit reworks the way we handle these (specifically starting
connections) by first serialising the requests, and then performing them
in multiple threads concurrently; which yields a significant loading
performance and reliability increase.
This URL library ends up being a relatively fundamental base library of
the system, as LibCore depends on LibURL.
This change has two main benefits:
* Moving AK back more towards being an agnostic library that can
be used between the kernel and userspace. URL has never really fit
that description - and is not used in the kernel.
* URL _should_ depend on LibUnicode, as it needs punnycode support.
However, it's not really possible to do this inside of AK as it can't
depend on any external library. This change brings us a little closer
to being able to do that, but unfortunately we aren't there quite
yet, as the code generators depend on LibCore.
It's no change in application behavior to have these objects owned by
the function-scope static map in Protocol.cpp, while allowing us to
remove some ugly FIXMEs from time immemorial.
Now we will only load resources from $build/share/Lagom. On macOS, we
load from the bundle directory Contents/Resources instead. This
simplifies the commands and environment variables needed to execute
Ladybird from the build directory, and makes our install setup less
awkward for distributions and packagers.
Add a RequestServerService class that uses the LadybirdServiceBase class
added previously. Bind to it from the WebContentService's service_main()
during startup.
This template app from Android Studio should hopefully be more fun to
work on than the Qt wrapped application we were using before. :^)
It currently builds the native code using gradle rules, and has a stub
WebViewImplementationNative class that will wrap a c++ class of the same
name that inhertis from WebView::ViewImplementation. Spawning helper
processes and creating proper views in Kotlin is next on the list.
Ladybird's RequestServer needs to depend on its generated IPC header
files to ensure they are generated before RequestServer is compiled,
which we currently bundle into LibWebView.
LibTLS still can't access many parts of the web, so let's hide this
behind a flag (with all the plumbing that entails).
Hopefully this can encourage folks to improve LibTLS's algorithm support
:^).
