WebContent: Start work on browser process separation :^) The "WebContent" service provides a very restricted instance of LibWeb running as an unprivileged user account. This will be used to implement process separation in Browser, among other things. This first cut of the service only spawns a single WebContent process when someone connects to /tmp/portal/webcontent. We will soon switch this over to spawning a new process for each connection. Since this feature is very immature, we'll be bringing it up inside of Demos/WebView as a separate demo program. Eventually this will become a reusable widget that anyone can embed and easily get out-of-process web content in their GUI. This is pretty, pretty cool! :^)

LibWeb+WebContent: Add abstraction layer for generic font families Instead of hard-coding the names of system fonts to use for the CSS generic fonts (like "sans-serif", "monospace", etc.) we now call out to a Platform::FontPlugin and ask for the generic names.

LibWeb+LibWebView+WebContent: Add Web::Platform::ImageCodecPlugin This replaces the previous Web::ImageDecoding::Decoder interface. While we're doing this, also move the SerenityOS implementation of this interface from LibWebView to WebContent. That means we no longer have to link with LibImageDecoderClient in applications that use a web view.

LibCore+LibSystem: Move syscall wrappers from LibSystem to LibCore With this change, System::foo() becomes Core::System::foo(). Since LibCore builds on other systems than SerenityOS, we now have to make sure that wrappers work with just a standard C library underneath.
2021-11-23 06:59:50 -03:00
#include <LibCore/System.h>
LibIPC: Add IPC::take_over_accepted_client_from_system_server<Client>() This is an encapsulation of the common work done by all of our single-client IPC servers on startup: 1. Create a Core::LocalSocket, taking over an accepted fd. 2. Create an application-specific ClientConnection object, wrapping the socket. It's not a huge change in terms of lines saved, but I do feel that it improves expressiveness. :^)

LibWeb: Abstract the LibProtocol ResourceLoader connection This is the final component that required LibProtocol as a dependency of LibWeb. With this, we can now remove the dependency, and LibWeb no longer requires IPC to work :^)

#include <LibWeb/Loader/ResourceLoader.h>
LibWeb+WebContent: Add abstraction layer for event loop and timers Instead of using Core::EventLoop and Core::Timer directly, LibWeb now goes through a Web::Platform abstraction layer instead. This will allow us to plug in Qt's event loop (and QTimer) over in Ladybird, to avoid having to deal with multiple event loops.

LibWeb+WebContent: Move Serenity EventLoop and Font plugins into LibWeb These are exactly what's wanted by headless-browser too, so this saves us some duplication. LibWeb already links LibCore so it should not cause any issues for Ladybird.

Userland: Link directly against LibUnicodeData where needed This is partially a revert of commits: 10a8b6d4116c6a627a6c189154af032f69b29c21 561b67a1add82538502ef2f5733f1d86718898ad Rather than adding the prot_exec pledge requried to use dlopen(), we can link directly against LibUnicodeData in applications that we know need that library. This might make the dlopen() dance a bit unnecessary. The same purpose might now be fulfilled with weak symbols. That can be revisted next, but for now, this at least removes the potential security risk of apps like the Browser having prot_exec privileges.
