 2024-10-13 22:03:15 +03:00
Bananymous d36b64e0c8 LibImage: name color to u32 function to to_argb from to_rgba 
This is the actual format that it returns
 2024-10-13 22:01:46 +03:00
Bananymous 8adc97980a Shell: rewrite the whole shell to use tokens instead of raw strings

Bananymous 0b05e9827b BAN: Use memmove instead of memcpy on overlapping data 
I was accidentally using memcpy where memmove was needed
 2024-10-13 22:00:16 +03:00
Bananymous 1c1a76d6d7 BAN: Member function pointers now use references instead of pointers

 2024-10-13 22:00:16 +03:00
Bananymous df4f37d68d BAN: only define placement new operators for banan-os targets

Bananymous 2da6776451 BAN: Update {Byte}Span API with better constness 
const BAN::Span<int> is now allowed to modify its underlying data, but
the container itself is const.

BAN::Span<const int> can be used for spans over constant data.
 2024-10-10 21:53:23 +03:00
Bananymous a68f411024 BAN: Add requires clauses for Container::emplace{,_back} functions

support cursor position querying
 2024-10-07 18:01:32 +03:00
Bananymous f67cad326a Shell: Don't crash when there are no tab completions available :D 2024-10-07 14:26:07 +03:00

command with ctrl+c
 2024-10-07 04:10:25 +03:00
Bananymous 1824988b9a Shell: Add support for simple aliases

a good start.
 2024-10-07 04:09:38 +03:00
Bananymous c54d9b3f60 Shell: Implement simple tab completion for commands and files 2024-10-07 01:44:44 +03:00

 2024-10-07 01:44:44 +03:00
Bananymous 6f90974896 BAN: Fix StringView::starts_with 
I have no idea what i had been thinking when writing this code :D
 2024-10-06 06:23:25 +03:00
Bananymous 4f3c05851c Shell: Expand ~ to home if its at the start of non quoted argument 2024-10-06 01:38:43 +03:00
Bananymous 4b13055125 Shell: Make builtin exit command read exit value from argument

 2024-10-05 19:07:59 +03:00
Bananymous f709e88994 Shell: Cleanup argument handling and exiting 2024-10-04 17:54:01 +03:00

Bananymous 7223e581a2 WindowServer: Fix 32 bit compilation with -Werror 
There was a always false statement on 32 bit that the compliler was
warning about.
 2024-09-27 15:33:25 +03:00
Bananymous 2d11ce9669 Kernel: Fix interrupt system 
I had not understood how MSIs work and I was unnecessarily routing them
through IOAPIC. This is not necessary and should not be done :D

Also MSIs were reserving interrupts that IOAPIC was capable of
generating. Now IOAPIC and MSIs use different set of interrupts so
IOAPIC can use more interrupts if needed.
 2024-09-27 15:31:31 +03:00
Bananymous e4982a1a5c LibC: Fix printf with alternate format and zero values 2024-09-26 15:25:16 +03:00

This allows vim's visual selection to show up
 2024-09-26 15:08:11 +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

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 39802b56c1 Kernel: Allow SYS_EXEC to fail at any point 
This patch builds new executable image to another pml4 structure and
only after everything is validated will current context be replaced.
This allows exec to fail "late" where previously it would panic the
kernel or kill the process. This allows graceful handling of exec
failures in userspace!
 2024-09-24 16:29:38 +03:00
Bananymous ebb87ccdde Kernel: Add asserts for overflow checks with ms -> ns conversions 2024-09-24 16:28:44 +03:00
Bananymous f0e55938c1 Kernel: Allow initial binding of threads to specific processor 2024-09-24 16:27:40 +03:00
Bananymous 348d04f7f5 Kernel: Implement static Process::kill() 
This allows killing processes even when there does not exist a current
thread.
 2024-09-24 13:16:43 +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 d395cf38b7 Kernel: Binding to port 0 will always find unused port 2024-09-22 17:30:01 +03:00
Bananymous 57aec2a733 Kernel: Validate pointer's when printing stack trace 
There was an kernel panic if stack trace contained uncanonical
addresses.
 2024-09-22 17:16:01 +03:00
Bananymous ae89237453 Kernel: Disable warning when calling syscall 
This warning is only generated when compiling with UBSAN and I don't see
how the value would even be uninitialzed.
 2024-09-22 17:15:07 +03:00
Bananymous 60d5257678 Kenrel: Add __builtin_unreachable support for UBSAN 2024-09-22 17:14:36 +03:00
Bananymous d59463d11b Kernel: Fix TTY reading one keyevent after disabling input handling 2024-09-22 17:13:10 +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 23d6205659 Kernel: Move DEBUG_* macros to centralized Debug.h 
This makes toggling debug info much easier

Bananymous b8622f2b4b Kernel: Implement simple RTL8169 driver 
This allows me to use internet when running banan-os on my hardware!
 2024-09-19 22:58:03 +03:00
Bananymous 7f0c39fe91 Kernel: Don't crash the kernel if packet is smaller than ethernet hdr 2024-09-19 22:51:55 +03:00
Bananymous a489be0e05 Kernel: Allow parallel LAPIC timer initialization with HPET 
HPET supports reading LAPIC counter without locks, so it can be done in
parallel. This makes booting much faster. Previously initializing every
timer took 100 ms, so 16 CPUs took total of 1.6 seconds. This allows
doing it all in 100 ms.
 2024-09-19 14:41:59 +03:00
Bananymous 8e08046519 Kernel: Add asserts about having locked TTY's write lock 
This for some reason fixes booting on real hardware? :D
 2024-09-18 00:56:48 +03:00
Bananymous 999eb53364 Kernel: Release debug lock if its locked during kernel panic 
Also kernel panic now prints if it had lock
 2024-09-18 00:56:02 +03:00
Bananymous f7e549e412 Toolchain: Run strip after installing toolchain 
This drops installed toolchain size to around fifth :D
 2024-09-17 22:30:40 +03:00

Bananymous f1a4bbce53 Kernel/LibC: Implement all stat family functions with fstatat 
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
