3403 5891 d 13 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3203 5961 d 12 h svoboda /branches/dynload/ Move stuff related to running programs to a separate source file proc/program.c  
3191 5967 d 11 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3190 5967 d 11 h svoboda /branches/dynload/ Remove vestiges of loading code coming from trunk  
3155 5981 d 7 h svoboda /branches/dynload/ Make loader less chatty and let init use it, instead of loading binaries itself.  
3153 5981 d 10 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3150 5981 d 11 h svoboda /branches/dynload/ Merge trunk changes up to r3090 into dynload (still broken)

3004 6002 d 9 h svoboda /branches/dynload/ A crude task_spawn() libc function to run a program. A tiny command-line application 'cli' to test it.  
3001 6003 d 9 h svoboda /branches/dynload/kernel/generic/ Kernel support for running programs from userspace.  
2927 6013 d 14 h decky /branches/dynload/ added dynload branch  
2802 6053 d 13 h jermar /trunk/kernel/generic/ Fix initialization of answerbox->task in ipc_answerbox_init.
Contributed by Jiri Svoboda.
 
2745 6091 d 12 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2712 6117 d 10 h decky /trunk/kernel/ prettyprint output  
2632 6178 d 23 h decky /trunk/kernel/generic/src/proc/ try to kill the tasks fewer times by introducing a delay in iterations  
2504 6304 d 5 h jermar /trunk/kernel/generic/ Give the AVL tree walkers the possibility to take an argument.
Each walker is now supposed to return a bool value to support walk termination.

Switch over from the tasks_btree B+tree to tasks_tree AVL tree.
This makes the fix for ticket #48 complete.
 
2446 6362 d 8 h jermar /trunk/kernel/generic/ More efficient and simpler task termination.

Based on the assumption, that after its creation, only the task itself can create more threads for itself,
the last thread with userspace context to execute thread_exit() will perform futex and IPC cleanup. When
the task has no threads, it is destroyed. Both the cleanup and destruction is controlled by reference
counting.

As for userspace threads, even though there could be a global garbage collector for joining threads, it is
much simpler if the uinit thread detaches itself before switching to userspace.

task_kill() is now an idempotent operation. It just instructs the threads within a task to exit.

Change in the name of a thread state: Undead -> JoinMe.
 
2436 6364 d 4 h jermar /trunk/ Fix two memory leaks.

In kernel, kernel_uarg structure needs to be deallocated when a thread
with userspace context is destroyed.

In userspace, the return value of the SYS_THREAD_CREATE must be checked
for error conditions and in case of error, uarg and stack must be freed
up.
