1595 6626 d 10 h palkovsky /kernel/trunk/ Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.
 
1594 6626 d 16 h jermar /kernel/trunk/generic/src/mm/ Never ever walk a B+tree as you destroy it. Or vice versa.  
1593 6626 d 17 h jermar /kernel/trunk/generic/src/synch/ When interrupted from sleep, pending timeouts must be unregistered.  
1591 6626 d 19 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1589 6626 d 22 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6626 d 23 h jermar /kernel/trunk/generic/src/ In task_kill(), remove the task from the tasks_btree before proceeding.
Thus, when the kernel finds the task in the tasks_btree and locks it before
releasing tasks_lock, it is guaranteed that the task will not be destroyed
until the lock is held. If the kernel needs to unlock the task, do some operation
and lock it again, it should increase its refcount before doing so. In that case,
when releasing the lock, it must decrement the refcount and if it reaches
zero, it must call task_destroy().
 
1587 6627 d 0 h jermar /kernel/trunk/ task_destroy() implementation, fixes in as_destroy() and task_kill().
This is the first version of HelenOS that would perform complete cleanup leading from thread to destruction of address space.
 
1586 6627 d 3 h jermar /kernel/trunk/generic/src/synch/ futex_cleanup() implementation.  
1585 6627 d 3 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6627 d 6 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1582 6627 d 7 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1581 6627 d 9 h jermar /kernel/trunk/generic/src/ Detach kmp thread after joining it.
Extend assertion in thread_destroy() to not panic when threads are destroyed in their Unded state.
 
1580 6627 d 9 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6627 d 19 h jermar /kernel/trunk/generic/ Framework for task_kill().
Some pieces (e.g. implementation of ktask_cleanup() kernel thread and
task_destroy() function) are missing.
Changed locking order for task lock, threads_lock and thread lock from
threads_lock, thread lock, task lock to task lock, threads_lock, thread lock.
 
1576 6627 d 21 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.
 
1573 6628 d 0 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.
 
1571 6628 d 0 h jermar /kernel/trunk/generic/ thread_join_timeout() and thread_detach() implementation.
Needs more thorough testing.
 
1570 6628 d 0 h vana /kernel/trunk/arch/ia64/src/ski/ Ia64 keyboard extension  
1568 6628 d 1 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.
 
1554 6628 d 19 h jermar /kernel/trunk/generic/src/mm/ Improve comment in slab.c.
