* Speed improvements
* Crash fixers
* Significant overhaul to escape handling based on extensive use of the
new serial console and a remote connection to a Linux box.
* Updated included terminfo file to accurately reflect terminal
behavior.
Some fun facts:
* vim runs great on a remote console (though the serial line slows a lot
of things down, it still runs rather smoothly)
* going to fix GNU screen, maybe in next commit, dunno
* tested with htop, less, and a bunch of other stuff
* fix some terminal bugs (some, not all)
* add a serial device to the VFS
* fix up serial so it works better
* add a serial-console application
* fix a bug in some other stuff relating to allocations
* change size of the terminal described by toaru.terminfo
* adds a new system call
Kernel driver sends raw scancodes, compositor or terminal handle the
rest. Support for F* keys will be added soon, in the mean time userspace
applications can know about the status of modifiers (control, shift,
alt, and super).
Compositor actions have been changed to Alt+Left Click for move and
Alt+Middle Click for resize. I'll work on adding more mouse events once
I get them to be faster (they're annoyingly slow at the moment... I want
more accuracy and less latency).
Also add functionality to the terminal to toggle it on and off.
There's a small, but nice-to-have performance increase from disabling
alpha transparency in the terminal.
Also, the display server sets DISPLAY=... to the shmem endpoint for the
compositor, so if getenv("DISPLAY") returns a pointer, you can assume
you are in a graphical environment, instead of having to rely on things
like arguments. Good for those applications that want to be able to run
both full-screen and windowed.
* Patched crt0 to support a pre_main
* pre_main sets up environment variables, can do other things later,
but then just jumps to main with the same arguments.
* Updated a bunch of apps to pass environment variables around.
The compositor itself still needs work, but the compositing engine
within now does full blitting and is faster than the old method.
Transparency is now supported properly, though telling the compositor to
use it on a window will degrade performance. One terminal is usually
okay, and everything runs faster than it did before; two terminals is
pushing it; three will make you very sad. The stacking logic has also
been updated. Presumably, alpha blitting for transparent windows could
be done with SIMD instructions and be extremely fast.
All graphics libraries have also been updated to (hopefully) work
properly with alpha bits.
* Fresh new wallpaper as a PNG from gnome-look:
http://gnome-look.org/content/show.php/Echo?content=137142
(By user hyperdude111, released as "do whatever you want")
* Terminal bug fix for --geometry option, which was derping on height
vs. width.
* Compositor bug fix for wallpaper app not showing up at the bottom.
Fixed by doing a better job of reordering the windows on a REORDER
call (which we weren't actually doing).
It's an editor, but it is incomplete. For example, write is not
supported yet, so you can open existing files and make modifications,
but you can not save them. Use it as a fun little scratchpad, I guess.
\033[1003z will stuff them into stdin like 80,24.
This is a hack, just like the "disable local echo" hack used for
passwords and it should, ideally, be replaced with a proper system as
defined in POSIX for terminal control, but for, it works, and that's
pretty cool because it means `ls` can stop being stupid.
* Some applications now support UTF-8 text through the use of a very
simple decoder.
* The terminal uses a slow, but accurate method to determine the width
of a character the first time it is printed to the screen. Characters
are now stored in the terminal in two bytes, rather than one, and may
in the future be increased to 3 or 4 bytes to ensure support for
Unicode supplemental planes.
* A simple font-fallback method is employed in the applications that
support unicode that will make use of the VL Gothic fonts if the
DejaVu font does not have a character. No guarantees are made for
support of writing systems other than extended Latin and Japanese.
* Finally bring syscall.h up to speed and include all syscalls in the
syscall module of the C library.
* Remove the third-party obfuscated C demos (we have nyancat, good
enough)
* Fix userspace apps to build without complaining about undeclared
strtok_r by disable __STRICT_ANSI__
* Fix .eh_frame by including the proper stuff with libgcc.
- Can now register a userspace file descriptor as the output for kernel
print statements through kprintf()
- Can set logging levels for debug print messages, which are separate
from kernel log events and meant to be more readily visible. Log
events are recorded in a buffer to be viewed later, though nothing
actually using logging at the moment.
- Serial output is disabled by default now. You can enable it yourself
by appending the logtoserial argument to the kernel on boot.
This is an automated system by which we boot qemu headless and use the
serial line to capture output from a testing application that is started
on bootup, running with the VGA terminal shell. This might be expanded
to boot to the graphical display within VNC and perform more advanced
tests with the Python shim using a VNC module for Python; we'll see.
All graphics library commands now take a gfx_context_t pointer, which
points to a simple datastructure describing a rendering context (width,
height, depth, total size, front buffer, backbuffer; where backbuffer =
front buffer when not in double-buffering mode, thus we always render to
backbuffer except on a flip). This may have caused a minor speed
reduction, but I don't really care as it's far more important that we
support multiple graphics contexts.
TODO:
- Shared Memory Fonts library (there are a couple of apps that use these
so-called "shmem fonts" on their own; we need a dedicated library for
them)
- Break off "TTK" GUI toolkit into its own library. Since it's just a
callback-based button framework, this shouldn't be too hard right now.
Also, with the previous tick, I'll be able to put labels on controls
and start using text in more places.
We know longer accept DAMAGE and REDRAW commands. Instead, we just loop
and redraw everything anyway (efficiently, mind you). Pipes still have
issues when closed and various other different things.
