4013 5588 d 3 h svoboda /trunk/kernel/generic/ Didn't need strrcpy() afterall. Also remove strcpy() since strncpy() is better.  
4011 5588 d 5 h svoboda /trunk/kernel/ String functions should be declared in string.h (and implemented in string.c) in the kernel.  
3988 5589 d 4 h svoboda /trunk/kernel/generic/src/proc/ Fix misaligned columns (whoops).  
3987 5589 d 5 h svoboda /trunk/kernel/ Read command line for multiboot modules on ia32 and copy it to task name. Other arches will need to initialize task names in the init structure to an empty string.  
3983 5589 d 11 h svoboda /trunk/ task_set_name() syscall so that we can have names (for userspace-loaded) tasks again.  
3908 5602 d 7 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3620 5687 d 15 h svoboda /trunk/kernel/generic/ Move stuff related to kbox to a separate struct.  
3566 5702 d 16 h svoboda /trunk/ Set meaningful names for loaded programs. Now 'tasks' kconsole command is much less obscure.  
3438 5754 d 14 h svoboda /trunk/ Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.  
3359 5778 d 15 h jermar /trunk/kernel/generic/src/proc/ Improve comments in task.c  
3222 5825 d 10 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3186 5840 d 8 h jermar /trunk/kernel/ Support for active mutexes. Active mutexes implement busy waiting, pretty much
in the same way as spinlocks, but can be passed to condition variables, which is
the motivation for this enhancement.		  
3137 5849 d 14 h jermar /trunk/kernel/generic/src/proc/ Maintain cache coherence after sys_task_spawn() copies ELF image from user space.  
3063 5860 d 11 h decky /trunk/kernel/generic/src/proc/ support for SYS_SPAWN syscall
proper printf formatting
change the way init tasks are created		  
2802 5919 d 15 h jermar /trunk/kernel/generic/ Fix initialization of answerbox->task in ipc_answerbox_init.
Contributed by Jiri Svoboda.		  
2745 5957 d 14 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2712 5983 d 12 h decky /trunk/kernel/ prettyprint output  
2632 6045 d 1 h decky /trunk/kernel/generic/src/proc/ try to kill the tasks fewer times by introducing a delay in iterations  
2504 6170 d 7 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 6228 d 10 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.
