Bananymous f6b91578ae LibC: Enable backtrace dumping by default 
I'm not sure why I had turned this off

Bananymous e03a26cf01 LibC: Don't ASSERT in times 
Return the current process CPU time as user time. We don't have a way to
get system/user time separation or CPU times of child processes

Bananymous 2a3eca5b36 LibC: Implement POSIX binary search trees 
I used RB tree for this. The implementation is based on the code on
wikipedia about RB trees.

Bananymous 3148c28c3d userspace: Add basic find utility 
This is mostly working but is missing -exec and -ok support. It can
search files though :^)

Bananymous fa89645542 userspace: Implement simple sort utility 
This supports most(?) options except for the separate fields. Should
work for simple use cases

Also merge is currently just a wrapper around sort so its not optimized
:D

Bananymous 2e9f7077c9 TaskBar: Fix division by zero error 
If a CPU does not have updated stats to show, just display ??.??%

Bananymous 304f94f3b1 LibC: Implement __fpending 
Some gnu programs want this and I don't want to make FILE non-opaque

Bananymous 20392c6cc1 LibC: Add malloc.h with some GNU extension 
This adds `reallocarray`, `malloc_usable_size`, `mallinfo`, `mallinfo2`

Bananymous 896bb05073 LibC: Cleanup qsort implementation 
Remove random template and just make qsort be a wrapper around qsort_r

Recurse only into the smaller partition. This removes the possibility of
O(n) recursion in the worst case

Use insertion sort for ranges shorter than 16 elements.

Split qsort_swap into qsort_swap_fixed and qsort_swap_general
- fixed one handles 1, 2, 4 and 8 byte elements which can be done directly
with mov instructions
- general copies 64 bytes at a time followed by a single copy for the
  rest. the 64 byte chunk loop gets nicely optimized into sse

Bananymous eee0b7c3ff Kernel: Make ioctl take unsigned long instead of int 
this is what linux does :D

also fix one or two `return ioctl` instead of `return ioctl_impl`

Bananymous ea4e016b1e DynamicLoader: Fix TLS memory initialization 
I was reading the TLS data before performing relocations so any TLS
variables pointing to relocated objects would not get the correct data
 2026-07-05 13:53:20 +03:00
Bananymous 3e16e69602 LibC: Implement qsort_r 
This is not really required by anything but i've seen few ports
optionally use it if available. This was trivial to implement so why not
add it :^)
 2026-07-05 01:55:57 +03:00
Bananymous ac1fafedcc LibC: Cleanup and fix random functions 
I was getting the size of random state incorrectly and ended up with
double the size user gave us leading to OOB access :D

Also remove hardcoded type -> size mappings and just use a looup table

Bananymous 2957206718 LibC: Fix and cleanup stdio mode string parsing 
The code is now much cleaner andd we are not as strict with the mode
string. Also add support for new 'e' and 'x' modifiers

Bananymous 652e170da9 LibGUI: Ignore failing smo maps in resize event 
This can be caused by sending two back-to-back resize requests. When
handling the first, the server may have already replaced the smo key
with a new one.

Bananymous 63b2284324 Kernel/LibC: support RDTSCP based clock_gettime 
RDTSCP seems to be faster than LSL and it removes the need for getting
the current cpu twice to make sure TSC is read on the correct CPU
 2026-07-03 06:32:04 +03:00
Bananymous 917321eb5f LibC: Wait for thread before returning from pthread_create 
We now make sure the thread starts up and sets its id. There was a race
condition where a process could create a thread and immediately try to
join it. If the thread had not initialized itself the join would fail
with EINVAL as we passed -1 as its id.

Bananymous 0a8b03d349 LibAudio: Make AudioLoaders return float instead of double 
AudioBuffers already use floats internally so there is no need for
loaders to produces doubles
 2026-07-02 22:54:45 +03:00
Bananymous 4473ee4d49 LibAudio: Add an API to query free space in audio buffer

This adds support for pthread function for stack manipulation.

Also keep track of main threads stack in the uthread

Bananymous 7bdd9d19d0 LibC: Cleanup uthread initialization 
This is now done in a constructor function in pthread.cpp
 2026-07-02 20:02:24 +03:00
Bananymous b19b7f064a LibC: Make pthread_t pointer to uthread instead of a thread id 
This will allow getting info about other threads in userspace!
 2026-07-02 20:02:24 +03:00
Bananymous f449ca8161 Kenrel: Separate pthread API from kernel API 
It didn't really make sense for the syscalls to be named as the pthread
equivalents. Now the kernel just uses thread ids

Bananymous d241975ce1 Kernel: Remove SYS_SLEEP and cleanup SYS_NANOSLEEP 
`sleep` is now implemented in terms of `nanosleep`. `nanosleep` is now
more precise and handles overflow when calculating wakeup time. I don't
think anything was depending on this, but I could see a program sleeping
for max time to block until signal.
