Bananymous a5a097fa4a Kernel/LibC: Add initial pseudo terminal support 
This patch implements posix_openpt() and ptsname()

for lookup.
 2024-08-09 16:55:52 +03:00
Bananymous 0c8cae4cc3 LibC: Move ioctl to <sys/ioctl.h>

that the stack actually exists
 2024-08-09 15:58:56 +03:00
Bananymous 2a659a9d03 BuildSystem: Fix enable sse definition

 2024-08-07 17:01:35 +03:00
Bananymous fe94d6cf89 LibC: Implement dummy rename() so vim can save files 
vim calls rename when saving a file. This patch adds dummy
implementation that only works for regular files and does a copy instead
of proper rename.
 2024-08-05 20:16:05 +03:00

 2024-08-05 00:55:03 +03:00
Bananymous e7a06979ec LibC: Implement usleep() 
This is not a POSIX function, but some ports seem to be using it either
way

Bananymous edc30cd71d LibC: Compile without exceptions 
This allows libc to not require __gxx_personality_v0. I can maybe add
C++ back to libc... :D I don't know why I did not research earlier what
this symbols was used for
 2024-07-31 23:33:41 +03:00
Bananymous 10ce03a1e7 LibC: Implement ctime() and asctime() 2024-07-31 23:26:10 +03:00

Bananymous e52dac3b25 LibC: Implement tmpnam() 
This implementation is not really spec compliant as rand() does not
guarantee TMP_MAX different outputs + seeding
 2024-07-30 12:02:30 +03:00
Bananymous 62db9a8ef3 LibC: Implement C++ static guards 2024-07-30 12:02:05 +03:00

 2024-07-30 11:10:43 +03:00
Bananymous e00efca170 Userspace: Pprogram template and loadfont mark install as optional 2024-07-21 17:41:40 +03:00
Bananymous 3ab1214012 LibC: Fix _toupper and _tolower definitions

Bananymous a5cb4057f9 Kernel: Implement unified input files for device hot-plugging support 
/dev/keyboard and /dev/mouse can be read for events from any attached
keyboard or mouse respectively. This makes device hot-plugging support
pretty much automatic for TTY, GUI, and whatever takes input.
 2024-07-15 22:11:15 +03:00
Bananymous 442ea8a692 BAN: Remove Optional emplace constructor 
This was kind breaking some initializations. Emplacing is still possible
through Optional::emplace
 2024-07-14 01:53:50 +03:00
Bananymous a97a574718 Kernel: Rewrite the whole input system 
PS/2 code is now kind of messed up, but it works. Keyboards and mice are
now an abstract class that is automatically exposed to userspace. This
will make adding USB input much nicer.
 2024-07-14 01:53:50 +03:00
Bananymous 8ddab05ed3 BuildSystem: Cleanup userspace directory layout 
userspace programs are now in userspace/programs
userspace tests are now in userspace/tests

This makes listing userspace projects much cleaner. Libraries were
already separated to their own directory, so other programs should also.
 2024-07-03 09:18:02 +03:00
Bananymous 5dc441c4af Kernel/userspace: Implement KD_LOADFONT and loadfont program 2024-07-03 09:02:49 +03:00
Bananymous d58a569660 WindowServer: Limit msync to 60 Hz and only sync necessary pages

60 Hz.
 2024-06-29 19:00:58 +03:00
Bananymous 0c645ba867 LibGUI: Window now uses double buffering 
This allows data in shared memory object be always up to date. With this
change window server can update lazily, and not necessarily on all
invalidate calls
 2024-06-27 00:39:59 +03:00
Bananymous f538dd5276 test-tcp: Fix printing of "connection reset" when tcp connection closed 2024-06-27 00:39:22 +03:00

http-server now implements basic static content from a specified
directory.
 2024-06-25 19:36:10 +03:00
Bananymous af4b138094 Kernel/LibC: Implement realpath 
realpath is implemented as a syscall. This is not really required but it
was the easiest way to get it working as there is already path
canonicalization at kernel level.
 2024-06-25 19:32:40 +03:00
Bananymous 95681a7a05 LibImage: Cleanup bicubic calculations 2024-06-25 11:04:03 +03:00

elevate the permissions.
 2024-06-24 15:00:08 +03:00
Bananymous 20aa7c79d1 BuildSystem: Fix crt file installation 
crt files should be installed always before userpace programs are
linked.
 2024-06-22 17:30:00 +03:00
Bananymous 22548a3f4a BuildSystem: Fix crt file installation 
crt files for userspace are now a dependency of libc, which means that
everytime libc gets installed, crt files will also install.

This fixes the problem when building libc
 2024-06-21 17:10:58 +03:00
Bananymous 9e1b5cbaab BuildSystem: Cleanup CMake code to allow libc only installation 
There was no way to just install libc which is required for stdlibc++
 2024-06-21 01:45:14 +03:00
Bananymous 1488ec5a03 Userspace: Implement the most basic http server 
This server just responds with static http "hello world" to every
incoming request
 2024-06-20 13:29:01 +03:00
Bananymous ad6d95ba52 BuildSystem: Rework the whole cmake build system 
Now files are installed using the install() command instead of manually
copying files to their destinations. This allows automatic recompilation
of headers that did not work previously
 2024-06-19 09:40:03 +03:00
Bananymous 318ce5dec8 All: Fix a lot of compiler warnings from header files 
While reworking build system, header files started to report warnings.
 2024-06-18 23:02:10 +03:00
Bananymous c69919738b BuildSystem: Move all userpace libraries under the userspace directory 
As the number of libraries is increasing, root directory starts to
expand. This adds better organization for libraries
 2024-06-18 13:14:35 +03:00
Bananymous aaf7a249c6 image: Add nicer error message if image could not be parsed 2024-06-17 22:58:59 +03:00
Bananymous dd64e2060e WindowServer: Add support for background images 
WindowServer now looks in _$HOME/.config/WindowServer.conf_ for a
configuration file that can specify a background image.

Also add default background image /usr/share/images/sample.ppm to the
base sysroot provided in the git repo.
 2024-06-16 00:28:09 +03:00
Bananymous 157e05f57c image: Implement --scale argument to scale image to framebuffer 
Also fix bug where red and blue channels were flipped
 2024-06-15 17:24:01 +03:00
Bananymous 672ce40618 LibImage: Move userspace image parsing to its own library

own.

Bananymous 843a6851c4 Userspace: Start work on a terminal emulator

support.

Shell's builtin start-gui now launches a Terminal instead of test
windows.

Bananymous c2b6ba0d5a Userspace: Start work on GUI and WindowServer 
Current implementation can create custom windows and each window has
its own framebuffer. When window wants to write its framebuffer to the
screen it will send a message to the WindowServer using unix sockets.
 2024-05-29 16:00:54 +03:00
Bananymous 8bc6c2eb20 Kernel: Move KeyEvent/MouseEvent from kernel to LibInput 2024-05-28 23:30:08 +03:00

family set and address in the storage field.
 2024-02-08 12:06:30 +02:00
Bananymous 2424f38a62 Userspace: Implement super simple DNS resolver in userspace 
You connect to this service using unix domain sockets and send the

I added -Wall -Wextra -Werror as public compile flags to libc. Now

necessary changes to allow compilation to work.

Only exception is execvp which has a large stack usage. Maybe it
should use malloc for the buffer but posix allows ENOMEM only when
kernel is out of memory... This can be fixed when fexecve is
implemented and there is no need for absolute path.

have it in kernel side, but for simplicity's sake I'm moving it
to libc for now :)

Bananymous b0ec0f1a1a Kernel: We add FixedWidthAllocators on demand 
On SYS_ALLOC we will add a new FixedWidthAllocator if the old ones
are already full or we don't have one with proper size. This allows
arbitary number of allocations as long as you have enough memory
available :)

Next I will be writing a general allocator for allocations larger
than 4096 bytes which should make SYS_ALLOC syscall complete :)
