3150 5863 d 12 h svoboda /branches/dynload/ Merge trunk changes up to r3090 into dynload (still broken)  
3149 5863 d 12 h svoboda /branches/dynload/ Merge trunk changes up to r3071 into dynload (broken)  
3004 5884 d 10 h svoboda /branches/dynload/ A crude task_spawn() libc function to run a program. A tiny command-line application 'cli' to test it.  
3001 5885 d 10 h svoboda /branches/dynload/kernel/generic/ Kernel support for running programs from userspace.  
2927 5895 d 15 h decky /branches/dynload/ added dynload branch  
2907 5898 d 10 h jermar /trunk/kernel/generic/src/proc/ Improve comment for thread_create().  
2802 5935 d 14 h jermar /trunk/kernel/generic/ Fix initialization of answerbox->task in ipc_answerbox_init.
Contributed by Jiri Svoboda.		  
2790 5941 d 15 h jermar /trunk/kernel/generic/src/proc/ Fix typo ALV tree vs. AVL tree.  
2765 5962 d 5 h jermar /trunk/kernel/generic/src/proc/ tasklet.c needs to include config.h  
2746 5973 d 8 h decky /trunk/kernel/ start merging tasklets (more or less a rewrite)  
2745 5973 d 13 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2712 5999 d 11 h decky /trunk/kernel/ prettyprint output  
2632 6061 d 0 h decky /trunk/kernel/generic/src/proc/ try to kill the tasks fewer times by introducing a delay in iterations  
2504 6186 d 6 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 6186 d 11 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 6213 d 7 h jermar /trunk/kernel/generic/src/proc/ Kernel stack address was printed twice.  
2470 6232 d 4 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 6241 d 5 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2446 6244 d 9 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.		  
2440 6245 d 4 h jermar /trunk/kernel/generic/ Fix the problem with sys_thread_create() by splitting the create and attach functionality of
thread_create(). Now it is possible to specify a flag that will cause thread_create() to only allocate and
initialize the thread structure. A call to thread_attach() will make the thread visible to the system.
This arrangement makes it easier to undo creation of a thread in case of a failure in sys_thread_create().
