3153 5926 d 5 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3150 5926 d 5 h svoboda /branches/dynload/ Merge trunk changes up to r3090 into dynload (still broken)  
3149 5926 d 6 h svoboda /branches/dynload/ Merge trunk changes up to r3071 into dynload (broken)  
3004 5947 d 3 h svoboda /branches/dynload/ A crude task_spawn() libc function to run a program. A tiny command-line application 'cli' to test it.  
3001 5948 d 4 h svoboda /branches/dynload/kernel/generic/ Kernel support for running programs from userspace.  
2927 5958 d 9 h decky /branches/dynload/ added dynload branch  
2907 5961 d 3 h jermar /trunk/kernel/generic/src/proc/ Improve comment for thread_create().  
2802 5998 d 8 h jermar /trunk/kernel/generic/ Fix initialization of answerbox->task in ipc_answerbox_init.
Contributed by Jiri Svoboda.		  
2790 6004 d 9 h jermar /trunk/kernel/generic/src/proc/ Fix typo ALV tree vs. AVL tree.  
2765 6024 d 23 h jermar /trunk/kernel/generic/src/proc/ tasklet.c needs to include config.h  
2746 6036 d 2 h decky /trunk/kernel/ start merging tasklets (more or less a rewrite)  
2745 6036 d 7 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2712 6062 d 5 h decky /trunk/kernel/ prettyprint output  
2632 6123 d 18 h decky /trunk/kernel/generic/src/proc/ try to kill the tasks fewer times by introducing a delay in iterations  
2504 6248 d 23 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.		  
2502 6249 d 5 h jermar /trunk/kernel/generic/ Replace the threads_btree B+tree with an AVL tree. The new variable is called
threads_tree. For printing list of threads, use the new AVL tree walker
mechanism.

This solves half of ticket #48.		  
2487 6276 d 0 h jermar /trunk/kernel/generic/src/proc/ Kernel stack address was printed twice.  
2470 6294 d 21 h jermar /trunk/ Fix a double-free recently introduced in revision r2436.
Add a comment clarifying the life-cycle of the kernel_uarg structure.

Comment out the freeing of userspace thread stack while still running on it.
This should be fixed by implementing userspace version of thread_join().		  
2451 6303 d 23 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2446 6307 d 3 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.
