Added more error checking to Connect() and Input/Output publishing.

of that list.
* Added a vfs_free_unused_vnodes() function that calls the low memory handler
directly.
* create_sem_etc() now calls the above function in case there are no semaphores
available anymore; this usually frees up to 2 semaphores per node (one from
the cache if there is a file cache attached, and eventually one from the
file system).

or vm_cache_ref couldn't be created, instead of cleaning up and returning
an appropriate error.
* vm_cache_ref_create() no returns a status_t instead of the vm_cache_ref
(as that's part of the vm_cache anyway).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16602 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added some comments
* Added some checking to avoid noop shifts
* Added buffer length checks
* Implemented (as Stephan suggested) a version of ConvertBits() that takes offsets.
This new version allows to move a region of the source into a region (possibly not at the same point) on the dest while converting colorspaces on the fly.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16592 a95241bf-73f2-0310-859d-f6bbb57e9c96
that put one or more full paths on the stack before, which could cause some
problems under certain conditions.
* Cleaned up KPath, ie. use size_t instead of int32 where appropriate, added
license.

* Shuffled functions in node_monitor.cpp around to clearly differentiate between
private, private kernel, and public kernel functions.

Colorspace conversion is not done yet so that it only works correct in 32bit modes.
Also drawCursor is not respected yet. Partially fixes bug 197.

resolution comes first). Doubled entries are automatically removed; this
fixes bug #192.

windows to front (or minimize them).
* Desktop::ActivateWindow() no longer crashes in case the window to be activated
is not on the current workspace - instead, it doesn't do anything at this
point. IOW it doesn't handle workspace activation at all, yet.
* Renamed ServerWindow::GetWindowLayer() to ServerWindow::Window().
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16550 a95241bf-73f2-0310-859d-f6bbb57e9c96
* AS_GET_STRING_WIDTHS now uses this method to send the strings to the app_server;
ie. it no longer sends the whole strings, and it saves sending the string length
separately.
* BFont::StringWidth() will now always return 0.0f in case of an error (instead of
some random value)
* Minor cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16525 a95241bf-73f2-0310-859d-f6bbb57e9c96
* all cursors owned by a team are visually different,
or (iaw) an already existing cursor is reused when
it is set by the client again
* changed various occurances of cursor data from "int8*"
to "uint8*"
* ServerCursors also remember the R5 data from which
they were created
* the reference counting and destruction of
ServerCursors changed: The cursor knows it is attached
to a CursorManager and one can simply use
ServerCursor::Acquire() and Release() and the reference
counting and everything is being taken care of
* destroying a ViewLayer will now correctly release a set
ServerCursor
* fixed a race condition when setting a cursor through
BView::SetViewCursor(): If the client code looks like this:
BCursor cursor(cursorData);
someView->SetViewCursor(&cursor, false);
there is a relatively high chance the BCursor destructor
told the ServerApp thread to destroy the cursor before
the ServerWindow thread got to "acquire" the cursor for
use by the view layer. The very same problem is likely the
reason that SetViewCursor works to unreliably on R5, even
when the "sync" flag is set to "true" (although it should
theoretically work in that case).
all these fixes make WonderBrush work fine again with the
new support of custom cursors.... coded by axeld and myself
(the joys of pair programming :-)

Sorry if I stepped on your toes Stephan, but I wanted these changes flushed before I leave for holidays :-).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16501 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Reordered some functions
* Area messages can now be unflattened instead of using the private _Reference and a special port code
Passing by area is now mostly working but it's not yet enabled. I will have to conduct performance tests first to see if and starting at what messagesize the overhead is reasonable.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16500 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added checksum generation and checking
The data itself is now checksummed too (unlike R5 where only the header gets a checksum). This might be a performance problem for larger messages. Opinions?
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16482 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Introduced a _SetStringValue() to avoid code duplication.
* The string types now check the original value, and don't write anything if the
contents stay unchanged (with the current exception of the sniffer rules).
* The monitor notfication methods no longer "clobber" the status result.
* Major cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16432 a95241bf-73f2-0310-859d-f6bbb57e9c96
all those error output from the app_server.
* AS_LAYER_DELETE now gets a token, no longer frightening choice of parent.
* Removed locking in RemoveChild(); it has to be called locked now.
* Removed AS_LAYER_DELETE_ROOT as it's no longer needed.
* Removed support from BView for being PR3 compatible.

Input server now saves keyboard typematic settings whenever they are modified,
instead of wating until it is shutdown (which never happens, either the
system will crash, or the input_server will stay active after a normal shut down)
Same problems might apply to mouse and keymap settings.
Input server shutdown handling should be reviewed.

what Be's implementation did wrong but instead of taking almost 30 seconds to
sort the MIME type database (roughly 1100 entries, and yes, that's why the
original FileTypes is that slow when it has to show the internal types), this
one needs only 4 ms for the same task (that's an amply 7500x speedup).
* Implemented some more missing functions - it's by no means complete yet, though.
* Rewrote OutlineListView.h, ListItem.h, and StringItem.h.
* Fixed some minor bugs, but there are probably a lot more.
* Major cleanup.

It might not work 100% correctly yet, but it works good enough to hide the Tracker

being called anymore in response to ResizeTo()

the device manager is initialized. For x86 it does nothing, but
for PPC it searches for a supported interrupt controller and
remembers it for later use.
arch_int_{enable,disable}_io_interrupt() are implemented as
well as handling of external exceptions (aka as I/O interrupts).
We'll see later how well that works.

traverse the device node tree without a node to start with.
* Fixed execution order problem in dm_get_next_child_node(). The

* Cleaned up TruncateString()
* Fixed a typo in moreUTF8.h

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16247 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Reworked functions like GetEscapements(), GetBoundingBoxesAsString() and GetGlyphShapes() completely
* Made the ServerFont functions uniform in their prototypes and cleaned out unnecessary arguments
* Added new UTF8 handling functions to moreUTF8.h that are now used by ServerFont
* Put the common transformations of the FT_Face into an own GetTransformedFace() to lessen code duplication
In other words, ServerFont is now cleaned and handles UTF8 pretty efficiently. Some ToDo's are still left though.

* You should no longer call HWInterface::SetCursor(), but the new Desktop::SetCursor()

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16238 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Fixed a myriad of bugs all over the place, ranging from locking errors to
deleting objects that don't belong to the one deleting them (hello HWInterface!)
* Almost all ServerWindow cursor stuff was broken; I've replaced all commands
to set a cursor with a single one AS_SET_CURSOR.
* Renamed some cursor commands.
* Changed the (broken) way ServerApp::fAppCursor was maintained - the application
cursor is now NULL as long as possible.
* Removed superfluous ServerCursor app signature stuff.
* The BApplication will no longer duplicate the default/I-beam cursors, it will
just reuse the default ones which now have fixed tokens.
* As a result, changing the cursor is now working as expected, closing bug #102.
* Rewrote Cursor.h, renamed private members to match our style guide.
* Minor cleanup.
What's still left to be done is reference counting the cursor objects to make them
work right and reliable.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16237 a95241bf-73f2-0310-859d-f6bbb57e9c96

time of the idle thread as a measure, we now compute the CPU activity on

* scheduler.c::sRunQueue::tail was not maintained at all; changed sRunQueue to

* Turns out we're monitoring CPU activity incorrectly when we've got more
than one CPU.
* Renamed the global CPU array from "cpu" to gCPU.

The test application lets run a thread at the highest priority that calls
yield all the time - the system stays responsible when it runs, so it seems

Changed the malloc implementation to use _kern_thread_yield() instead of

Minor fixes to the FD disconnection implementation:

code. The stack pointer was not adjusted, hence we were
overwriting the previous register value. But it looks like I
missed to check in the arch_cpu.h with the iframe structure
including the floating point registers anyway.
* Backported the ELF PPC relocation code from the boot loader to
the kernel.
* Fixed the PPC version of arch_thread_switch_kstack_and_call().
Apparently the signature had changed, but the assembly
implementation was not adjusted accordingly.
* sc prints more registers now (LR, CR, CTR, XER,...).
* Fixed several occurences of not-working fault handlers.
Apparently the compiler realized, that the "error" label was
never jumped to (by the code it knew), and optimized the
respective code away. Now we use a trick to make it think the
error label might actually be jumped to. I wonder whether the
x86 version has the same problem when being compiled with GCC4.
* Adopted the x86 page fault handling interrupt code.

in all drawing methods in case the parent window was
not in a "transaction" (fInTransaction). For ordinary
updates, nothing has changed, but if you call drawing
methods outside of an update, they will happen "immediately"
rather than when the link is sporadically full and auto
flushes. The effect is that the cursor in Terminal blinks
reliably, the selection in BTextViews follows the mouse
right on the spot (and so on). BWindow::BeginViewTransaction()
and EndViewTransaction() now have a meaning in Haiku too.

* Cloned iframe stack management from x86.
* Reimplemented arch_thread_{get,set}_current_thread(). The
thread structure is stored in SPRG2. It is set to NULL in
arch_cpu_preboot_init(), now. A non-null current thread
causes all kinds of undesired behavior in early boot code.
* We establish the address space mappings we know from the
Open Firmware as areas. At least those in kernel address
space. The ones in userland address space are tougher.
Fortunately on my Mac mini there aren't any save the
boot_loader stack, which is not needed any longer anyway.
* Added stack trace support to the kernel debugger. Mostly
cloned and adjusted the x86 code. Some bits are still
missing, like stack traces for other threads.

void after turning off BAT for the segment containing itself.
The monster macro for the exception vector code was not really
elegant besides being too long for the 32 byte performance
monitor exception slot. Furthermore wasting three of the SPRG*
registers as cheap scratch memory wasn't that nice either.
We now have a three-step approach: The exception vectors
themselves contain only five instructions which branch to common
code at the beginning of the same physical page. That one sets
up BAT for itself, turns address translation back on and jumps
into the kernel. There we turn off BAT again, dump an iframe,
and enter the actual exception handler (/dispatcher). Upon return
the registers are restored from the iframe and we get back to the
place where the exception occurred.

* fixed weird pointer conversion in SetStyle()
* fixed a potential mix up in operator=() in case the
other ServerFont has fStyle == NULL
ServerWindow:
* the WindowLayer fTopLayer cannot be deleted by
client request, just for safety reasons
* the link is flushed if there is no drawing engine,
but this case is theoretical only
* deleting the ServerWindow object syncs with the
client, so that when BBitmaps are deleted, they
can be sure there are no pending messages (which
would be executed in a nother thread)
* there is no timeout anymore when sending messages
to the client, which made absolutely no sense
AGGTextRenderer:
* renamed fFontManager to fFontCache, because that's
what it really is
* fLastFamilyAndStyle defaulted to the system plain
font and therefor that font was never loaded when
the font never changed meanwhile
DrawingMode:
* I'm not quite sure but I think there was the
potential of a division by zero, at least I
had crashes with "divide error"
HWInterface:
* fix update when the cursor shape changed in
double buffered mode
ViewLayer:
* since the top layer is never really deleted
before its time has come, it is not necessary
to set it to NULL in the ViewLayer destructor
ViewLayer/WindowLayer:
* added a function to collect the view tokens
that are affected by an update session
EventDispatcher:
* use the importance of the message for the timeout
in _SendMessage()
* drop mouse moved events in the server if we're
lagging behind more than 5 ms (Axel, maybe review)
View:
* there were some problems with the locking
of the BWindow looper in RemoveSelf(), since
this is called from the window destructor,
also of BWindows from BBitmaps, which have
never been run (this might need review), at
least I seem to have solved the crashing
problems introduced by actually deleting the
view hirarchy in the BWindow destructor
* fixed _Draw() for being used non-recursively,
temporarily disabled DrawAfterChildren, which
didn't work yet anyways (because views cannot
draw over children in the server yet)
Window:
* small cleanup when deleting shortcuts
* sync with the server when having send
AS_DELETE_WINDOW (see ServerWindow above)
* fixed locking in Begin/EndViewTransaction()
* removed folding of _UPDATE_ messages, since
there is only one ever in the queue
* set the fInTransaction flag during an update,
I plan to use this in BView later to
flush the link when drawing outside of an
update
* BView::_Draw() is now called by view token,
this gives the next leap forward in speed,
the overhead because of drawing clean views
was considerable

The time base conversion factor is the 32 bit value
2^32 * 1000000 / time base frequency,
so the system time can be computed by
system time = time base * conversion factor / 2^32.
The expression in system_time() looks more complicated now, but is
actually much faster (factor 2.5 on my Mac mini). I'm positively
surprised, how good the assembly looks, that GCC 4 generates. There's
not that much potential for optimization by hand-coding the function.

* The generic physical page mapper reserves the virtual address range
for the IO space now, so that noone can interfere until an area has
been created. The location of the IO space is no longer fixed; it
didn't look to me like it was necessary for x86, and we definitely
need to be flexible for PPC.

now run under BeOS as well (as long as they don't use any functions that are not
available under R5).
The solution is a bit messy, but we have to live with it :-)
The runtime loader now patches the __gRuntimeLoader symbol in libroot.so to point
to its exported structure instead of passing it to the init functions as an
argument.

device in the Open Firmware implementation of boot loader and
pass its path to the kernel, where it's opened and used for
getting/setting the real time. The expensive atomic_*64() on PPC
32-bit make things a bit more complicated. Moreover, missing
64 bit multiplication and division instructions won't really
allow system_time() to be anywhere near as fast as on x86. :-/

substructure now (that's the only member actually). The system time
offset is therefore accessed via architecture specific accessor
functions.
Note, that this commit breaks the PPC build. Since I want to rename at
least one file I've already changed, I can't avoid that.

* Fixed BShelf::_AddReplicant(), at least a bit. I managed to add the "ScreenChanger"
icon to the tray, although the icon was not drawn, and it was on the wrong
position.
* _AddReplicant() also did not reply to the waiting message source in case
of failure.

(year, month,...) representation out of the x86 specific code and put
respective support functions into real_time_clock.c. We'll need those
for the PPC specific part too.

Basically the architecture specific code is now responsible to
init and make use of the platform specific code, now. The reason
being that we have only one kernel per platform and thus cannot
decide at compile time, which platform to use (if any).
The PPC implementation features an abstract base class PPCPlatform
(implemented for all supported platforms) through which platform
support is provided.

bus, and time base frequency) in the PPC boot loader, and propagate
them to the kernel via kernel_args.
* Now we use the correct time base frequency for timer calculations.
* Implemented PPC specific system info stuff. Added a few PPC CPU
types to <OS.h>.

remapping stuff into separate functions and made them available to
others.
* Remap the exception handler space in arch_int_init_post_vm() into the
kernel address space (same issue as with the page table).

According to the spec we need to set it before taking over the MMU,
but we can't call it before arch_mmu_init(), since we need the OF
to allocate the page table. So we do it after we have allocated
the new page table.
* Added PPC specific kernel_args: The virtual address ranges we want
to keep in the kernel. We fill that in with the translations we
find when initializing the MMU stuff. We remove the memory the
boot loader occupies from those. Besides the stack for the boot
loader only the OF stuff remains.
* arch_mmu_allocate() now starts to search at KERNEL_BASE for a free
virtual address when no particular address is requested. This saves
us further trouble in the kernel, since those allocations would
need to be remapped otherwise.

brick wall collisions. Along the way I found a few defines that no longer
exist in Haiku - changed B_BEOS_VERSION_DANO to use Haiku versions (anyone
rebuilding under Dano might want to undo it). By the way, the BeOS version
number define system might be worth using, since it's a numerical compare
rather than #if defined(V1) || defined (V2) || defined (V3) and so on.
What sort of errors? Besides needing libzeta.so for some things, the
networking compatibility compile doesn't work (libbind and all that).
Some examples among many:

the fact that I couldn't find ptesync in an otherwise more complete
documentation I downloaded yesterday made me suspicious.
* arch_cpu_global_TLB_invalidate() uses tlbia now. The instruction is
optional, but so is tlbie (how I understood it is that both exist,
when the architecture implementation has a TLB). And the former loop
looked just scary.
* Implemented arch_cpu_user_TLB_invalidate(). It does just the same as
arch_cpu_global_TLB_invalidate().
* Some changes with respect to synchronization required on page table
and segment register updates.
* Some more minor renaming. Pulled a new function
remove_page_table_entry() out of unmap_tmap().
* In arch_vm_translation_map_init_post_area() we do now remap the page
table into the kernel address space, if it was without before. The
page table might actually be a good application for BAT, though.

{HAIKU,HOST,TARGET}_KERNEL_PIC_{CC,LINK}FLAGS which define the
compiler/linker flags specifying the kind of position independence
the kernel shall have. For x86 we had and still have -fno-pic, but the
PPC kernel has -fPIE (position independent executable) now, as we
need to relocate it.
* The boot loader relocates the kernel now. Mostly copied the relocation
code from the kernel ELF loader. Almost completely rewrote the PPC
specific relocation code, though. It's more correct and more complete now
(some things are still missing though).
* Added boot platform awareness to the kernel. Moved the generic
Open Firmware code (openfirmware.c/h) from the boot loader to the kernel.
* The kernel PPC serial debug output is sent to the console for the time
being.
* The PPC boot loader counts the CPUs now and allocates the kernel stacks
(made OF device iteration a bit more flexible on the way -- the search
can be restricted to subtree). Furthermore we really enter the kernel...
(Yay! :-) ... and crash in the first dprintf() (in the atomic_set()
called by acquire_spinlock()). kprintf() works, though.

* Less flickering when drawing the label: the area of the label is now
clipped, so there is no need to fill the background again.
* Consumed the last reserved member for the bounding box of the label.
* More or less rewrote the header.

as only the BitmapManager class is allowed to call them.

specifying whether only the exact supplied address is acceptable. If
false, the address is considered a hint only. It will be picked, if
available, otherwise a greater address is tried to be acquired, and
as last resort any address. This feature is only implemented for PPC.
It is needed since the preferred kernel text base address 0x80000000
might not be available (and actually isn't on my Mac mini).
* Fixed a bug in the PPC memory management code:
is_{virtual,physical}_allocated() were checking whether the given
range was completely contained by an existing range instead of
checking for intersection. As a consequence we could (and did) allocate
a range intersecting with already allocated ranges. The kernel segment
thus overwrote OF memory for instance.
* The ELF loader makes sure that it got both text and data segment of
the image to be loaded.
The PPC boot loader successfully loads kernel and modules now. Next
comes the hard part, I'm afraid.

IP, and UDP, as well as a home brewn UDP based protocol, "remote disk",
which provides random access to a single remote file/device. The Open
Firmware flavored boot loader automatically initializes the net stack,
searches for a remote disk, and tries to boot from it, if the boot
device is a network device (e.g. when loading the boot loader via
TFTP).
This is quite nice for developing with a two-machine setup, since one
doesn't even need to install Haiku on the test machine anymore, but can
serve it directly from the development machine. When the networking
support in the kernel is working, this method could even be used to
fully boot, not just for loading kernel and initial modules.
