This was only synchronous since WindowServer managed the ID allocation.
Doing this on the client side instead allows us to make create_menu()
an asynchronous IPC call, removing a bunch of IPC stalls during
application startup.
Previously accept() would copy the listener socket's cloexec and
non-blocking flag. With that fixed however TCPServer and LocalServer
now leak file descriptors into child processes and are blocking.
Unlike accept() the new accept4() system call lets the caller specify
flags for the newly accepted socket file descriptor, such as
SOCK_CLOEXEC and SOCK_NONBLOCK.
Previously struct sockaddr was used which isn't guaranteed to be
large enough to hold the socket address get{sock,peer}name() returns.
Also, the addrlen argument was initialized incorrectly and should
instead use the address length specified by the caller.
This changes Core::File::open() to specify O_CLOEXEC by default
so that we don't leak file descriptors into child processes. The
new behavior can be overriden by specifying OpenMode::KeepOnExec.
This commit adds support for the various ECHO* lflags and fixes some
POSIX conformance issues around newline handling. Also included are
error messages when setting not implemented settings.
Problem:
- Clang ToT reports an error because `digest_size` cannot be evaluated
at compile-time.
Solution:
- Change from using the member function to the `static` shadow of the
NTTP.
Because we don't parse ACPI AML yet, If we are not able to shut down
the machine with "hacky" emulation methods - halt and print this state
to the users so they know they can shutdown the machine by themselves.
This fixes a bug that was reported on this discord server by
@ElectrodeYT - due to the confusion of passing arguments in different
orders, we messed up and triggered a page fault due to faulty sizes.
This is not only easier to comprehend code-wise and avoids some function
overloads, but also makes resizing the board while preserving game state
*a lot* easier. We now no longer have to allocate a new board on every
resize, we just grow/shrink the individual row vectors.
Also fixes a crash when clicking the board widget outside of the drawn
board area.
These all looked out of place both when used on a regular button (e.g.
in the SoundPlayer application) and a toolbar action button (e.g. in the
GameOfLife application). This makes them a bit smaller (hand-drawn, not
scaled down).
If we create a VGACompatibleAdapter object with a preset framebuffer,
Always assign the console so we can use it.
This is useful for modesetting done by a Multiboot loader, like GRUB.
The current code is factored such that reads to the entirety of the last
byte should be dropped. This was relying on the fact that last would be
one past the end in that case. Instead of actually reading that byte
when it's completely out of bounds of the bitmask, just skip reads that
would be invalid. Add more tests to make sure that the behavior is
correct for byte aligned reads of byte aligned bitmaps.
As we removed the support of VBE modesetting that was done by GRUB early
on boot, we need to determine if we can modeset the resolution with our
drivers, and if not, we should enable text mode and ensure that
SystemServer knows about it too.
Also, SystemServer should first check if there's a framebuffer device
node, which is an indication that text mode was not even if it was
requested. Then, if it doesn't find it, it should check what boot_mode
argument the user specified (in case it's self-test). This way if we
try to use bochs-display device (which is not VGA compatible) and
request a text mode, it will not honor the request and will continue
with graphical mode.
Also try to print critical messages with mininum memory allocations
possible.
In LibVT, We make the implementation flexible for kernel-specific
methods that are implemented in ConsoleImpl class.
