Bananymous b6e040dfc2 Kernel/Shell: Fix backspace and delete key byte sequences 2024-10-04 04:14:47 +03:00
Bananymous 7223e581a2 WindowServer: Fix 32 bit compilation with -Werror

warning about.
 2024-09-27 15:33:25 +03:00
Bananymous e4982a1a5c LibC: Fix printf with alternate format and zero values 2024-09-26 15:25:16 +03:00

Bananymous 57ae74f908 Terminal: Implement more ANSI escape handling 
This patch adds L and M codes for inserting and deleting lines and SGR 7
for inverting colors
 2024-09-26 15:07:08 +03:00
Bananymous 1a6804b4b4 Terminal: Make Terminal::handle_csi() return invalidated rectangle 
When I updated Terminal to only do a single invalidation after all of
input text was printed, I forgot to change handle_csi
 2024-09-26 15:05:11 +03:00
Bananymous 82e6a3582d LibGUI: cleanup Window::shift_vertical and add copy_horizontal_slice 2024-09-26 15:00:14 +03:00

Bananymous 50a3533322 LibInput: Add value for ESC in key_to_utf8_ansi 
This allows exiting vim when using this function for key mappings :D
 2024-09-24 18:08:34 +03:00
Bananymous 4e9f39384a LibC: Initialize libc only once 
This was breaking stuff with dynamic loader initializing libc and main
executable reinitializing it later :D
 2024-09-24 17:56:12 +03:00
Bananymous 1b0086217c Terminal: Do scrolling in putchar if necessary 
I overlooked that handling *newline* scrolls would be enough. You can
definitely scroll more if printing a lot of text which wraps to the next
line.
 2024-09-23 15:00:47 +03:00
Bananymous 1280528e4e BuildSystem: Use -O2 for all libraries 
I don't know why I had not specified optimization level for libraries.
Only LibImage was using explicit -O3. LibImage doesn't need O3 anymore
as O2 seems to be around the same speed.
 2024-09-20 20:04:49 +03:00
Bananymous fbb99de728 ls: Show symlink target with `-l` 2024-09-17 19:12:34 +03:00
Bananymous a6b973003b WindowServer: chmod the correct file 2024-09-17 18:35:27 +03:00

This patch gets rid of 2 unnecessary syscalls!
 2024-09-17 16:38:01 +03:00
Bananymous 708a720d9d Kernel: Remove SYS_OPEN 
This can be done with SYS_OPENAT with fd set to AT_FDCWD
 2024-09-17 16:16:47 +03:00
Bananymous 7177da7d62 LibC: Implement dummy get_rusage 
One port seems to use this function. This dummy just reports no used CPU
time for current process nor children
 2024-09-17 15:59:22 +03:00
Bananymous d88ee5c9ee Kernel/LibC: Implement `creat` with `open` 
This allows getting rid of unnecessary SYS_CREATE. Directory creation
still has its own syscall, but I could combine it with SYS_OPEN also.
 2024-09-17 15:55:53 +03:00
Bananymous a084f83f4c Kernel: Rework kernel-side ELF loading 
ELFs are now loaded as MemoryRegions so they don't need special handling
anywhere. This also allows file backed COW optimizations to work. This
was not the case before.

This patch removes now obsolete LoadableELF and unused ELF files from
LibElf.
 2024-09-15 23:57:34 +03:00
Bananymous 1a24d1839f LibInput: KeyEvent to ansi string now handles delete key 
This allows Terminal emulator to also handle delete key.

The value of `\0x7F` may be wrong as qemu's serial console seems to be
sending `\e[3~`
 2024-09-15 03:13:21 +03:00
Bananymous c3040a04a3 Terminal: Optimize printing a lot 
Terminal used to run `yes` at around 400 lines per second

This patch pumps that to over 100'000 lines per second!

There are 2 optimizations done:
  1. only invalidate window once after rendering is done
  2. if printing more than `rows()` newlines skip prior data
 2024-09-15 03:12:26 +03:00

for WindowServer
 2024-09-12 19:34:25 +03:00
Bananymous bf01b935bd WindowServer: Start Terminal with Super+Enter

 2024-09-11 22:18:08 +03:00
Bananymous 98c011e6a6 WindowServer: Open all fds as CLOEXEC

Bananymous 8da2f12ba6 Kernel: Only load program headers of interpreter if its present 
I was loading program headers of both executable and interpreter but
that is incorrect. The interpreter will itself load the program headers
of the executable.
 2024-08-28 21:19:37 +03:00

- openlog
- syslog

For some reason some ports include these files even when they detect
that they are not available
 2024-08-22 14:47:59 +03:00

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