passed to kernel in which the hits are recorded. When the area is
full, the debugger is notified. For some reason that part doesn't work

Perhaps a private helper class could be refactored from these two controls
to avoid duplicating a lot of this code, although there are a few subtle
differences here and there.
These changes make a BTextControl behave properly in the layout management
frame work, in case CreateLabelLayoutItem() and CreateTextViewLayoutItem()

* Got rid of fSkipSetFlags member by simply calling the BView::SetFlags()
directly where fSkipSetFlags was supposed to prevent the custom

* The most important fix is that in BMenuField::_ValidateLayoutData(),
divider was calculated, but then never used. If the menu field was not
using the layout management, it should take the existing fDivider into
account, but never did. This caused #2728.
* Added some tracing that helped me debug this.
* Fixed a bunch of layouting inconsistencies. It will also improve some
unnecessary resizing of the menu bar.
Will test all of this some more. But in the test app I do have, the BMenuField
works more like in BeOS now.

* Add getter for active interface index and simplify the count operation as
it isn't misused to also get interface descriptors anymore.
* Refactor out some common code into helper functions.
* Adapt the USBKit to the changed/new interface.
* Change how alternate interfaces are exposed by USBKit by providing normal
BUSBInterface objects for alternate interfaces that can easily be examined
and used.
* Make BUSBInterface class aware of its alternate index and use the alternate
aware usb_raw functionallity to build the endpoint and descriptor lists.
* Add ActiveAlternateIndex() to find out what alternate is currently active.
* Style cleanup of the USBKit classes, use std::nothrow everywhere and check
all allocations. Simplify some code by removing optimization where the benefit
is questionable.

* Imported radix bitmap tree implementation from FreeBSD and adjusted it
for Haiku.
* Make use of the radix tree in the swap support implementation instead
of using simple bitmaps. This will allow for faster swap slot
allocations. ATM Haiku doesn't benefit that much, since we always
allocate single pages, but that will change eventually.

unscheduled was incorrect.
* Introduced _kern_analyze_scheduling() syscall. It requires scheduler
kernel tracing to be enabled. It uses the tracing entries for a given
period of time to do a similar analysis the "scheduler" debugger
command does (i.e. number of runs, run time, latencies, preemption
times) for each thread. Additionally the analysis includes for each
thread how long the thread waited on each locking primitive in total.
* Added kernel tracing for the creation of semaphores and initialization
of condition variables, mutexes, and rw locks. The enabling macro is
SCHEDULING_ANALYSIS_TRACING. The only purpose is to provide
_kern_analyze_scheduling() with more info on the locking primitives
(the name in particular).

vector at the end of the file will be aligned to the given value.
* BFS uses an alignment of 512 bytes (should be block size of the
underlying device or BFS block size, whatever is less), which should
be fine, since file data are only stored in BFS blocks. This totally
avoids any partial operations at the I/O scheduler level, thus saving
disk operations. Not that I could measure any performance difference.
Theoretically it should help a lot though, particularly when dealing
with lots of small files, since we avoid using bounce buffers, which
are (a) limited in number and (b) require copying of the data.

generate_boot_screen build tool. Only 4-bit screen support is missing now.
* Adopted images.h with the new results from generate_boot_screen.
This should fix black boot screens for graphics cards that don't support
true color modes for the native resolution. I've tried to find the ticket,
#2177 almost looks like the one, but it looks more like the mode is out
of range if I understand the ticket right.

Powel. The functionality was written by Jeff Prosise and Davide Pizzolato and

referencing iframe registers. Their prefix is "$". E.g. "$eax" refers to
the eax register of the current iframe. The features cooperates with the
"in_context" command, i.e. "in_context 92 $eip = 0" will set the eip
register of thread 92 to 0 (thus sealing its fate ;-)).

due to alignment padding before.
* Reorganized merging of caches a bit. Renamed MergeStore() to Merge()
and moved some more functionality into it. The method also moves the
pages from source to consumer, now. This is necessary, since
VMAnonymousCache needs to consider both physical pages and swap pages
at the same time. Before we first moved the physical pages and the
swap pages later, which was broken for two reasons: (1) A swap page in
the consumer cache shadows a physical page of the source cache, which
we ignored. (2) A source cache's physical page that also had a swap
page would lose the latter in the process when moved to the consumer
cache, i.e. if the page was not marked modified, it could be stolen
and its data would be lost.
These changes improve the situation when building Haiku with 256 MB RAM
in that jam doesn't crash anymore, but in my test the system became
totally unusable after about an hour or 7000 targets (GUI froze). For
some reason it didn't manage to free pages anymore although swapping
heavily.

of free objects an object cache should try to have ready. If the number
of free objects drops below the threshold, a new urgent priority thread
is asked to asynchronously resize the object cache (pretty similar to
the heap grower thread). Such a mechanism is necessary for code paths
that are supposed to free pages, but may need memory themselves (like
the swap support).

asynchronously. The base class version version falls back to the
synchronous Write(). Only VMVnodeCache implements WriteAsync() ATM,
VMAnonymousCache (swap support) still has to be adjusted accordingly.
* write_page() doesn't need to map the page anymore as it can write the
physical page directly.
* Modified the page writer to write pages asynchronously. This shouldn't
have any noticeable effect yet. It will though as soon as the I/O

- B_GET_ICON_NAME: returns the name of an icon. This will then be read from
a predefined location on disk (not yet implemented). This would also allow
to add specifiers like "-boot", or "-fat|bfs|ntfs|...", and have special
icons for those.
- B_GET_VECTOR_ICON: retrieves the vector icon of a device, if any.
* get_device_icon(BBitmap*, ...) now supports other color spaces than B_CMAP8.

variants that can also retrieve the icon data directly (like
BNodeInfo::GetIcon()).
* Reenabled the previous BPartition::GetIcon(), based on a patch by
Justin O'Dell - this fixes#1391.

we now have two local list, one per semaphore set and one per team

* The global BPathMonitor looper is now always used, no more optional looper
and no more BApplication looper usage. This way we know how the looper behaves
and PathHandler::Quit() can be synchronous. In the end, the bug I was
observing was not caused by the previous asynchronous node monitor stopping,
but this should be safer anyways. When BPathMonitor::StopWatching() returns,
you have really stopped watching and not some time later.
* Introduced "FileEntry" which is an entry_ref plus node id. This is now used
instead of the node_ref for the "watched files set". The whole point
is to really be able to add the "path" field to the B_PATH_MONITOR message.
Previously, the initial path that was passed to StartWatching() was added,
regardless if the message was for an entry somewhere down the hierarchy when
watching recursively. The downside of the new method is that it uses a lot
more RAM per entry. Another option would be to store the node id of the parent
directory and iterate the directory always when in need to construct the path.
* Watching a folder recursively now really adds all the existing subfolders
as well as all the files if not watching for folders only. The tests for the
old implementation only tested what happens when the watched folder was newly
created and then subfolders were created. Those where already added by the
code. Now it also adds the subfolders of folder that appear in a watched
folder.
TODO: Remove folders and files recursively when they dissappear. More testing
for B_ENTRY_MOVED. Optimizations are possible when some information is
retrieved twice. I am also planning to add a way for the BPathMonitor user to
filter the automatically watched files/folders in B_WATCH_RECURSIVELY mode.
I grepped the entire Haiku tree for usage of BPathMonitor. Only net_server
and Mail were using it, but both in a way that is not affected by these
changes. Anyways, TextSearch works more reliable now, even for entries in
subfolders.
Feedback very welcome! :-)

then be used for receiving node monitoring messages.
* Reenabled using be_app as default BLooper if the API user does not provide
one. I think the problem that Stefano needed to work aroung in r23995 was
actually caused by the incorrect locking (an never unlocking) of the looper
before calling PathHandler::Quit().
->If I understand correctly, this code as supposed to work around the possible
situation that the looper holding those PathHandlers may have already quit,
leaving stale PathHandler pointers behind. But that case was not prevented
by the old code anyways, since one would have had to access freed memory to
even get the stale BLooper pointer. The real fix would be to store the
BLooper pointer with each PathHandler so that the possible gone-ness of
those loopers could be checked independent of accessing the PathHandler
pointer. (The whole problem is that PathHandler adds itself to the BLooper
and if the looper quits, it will free all its attached handlers.)
* Introduced a global fallback BLooper for the case that no BApplication is
running, which resolves a TODO.
All this is yet untested, but should have a good chance of working.
(Famous last words...)

dedicated functions.
* Introduced gMappedPagesCount variable which counts the total number of
physical pages that are mapped.
* Added vm_page_get_stats() which fills in the memory related part of
the system_info structure. Used and cached pages are computed
differently, now. The "available" (== not committed) memory is no
longer used for the computation as it doesn't say anything about the
actually used/free pages (with swap support enabled it is even
less meaningful, since we first commit swap space when possible).
We do also consider the memory used by the block cache as cached
pages, now. All in all these changes should fix the memory statistics
reported by get_system_info(), IOW bug #2574.

architecture: for now, we do this on the lowest layer only, therefore all
requests are handled synchronously (ie. in the scheduler's thread).
* Instead of using the block_io module, scsi_disk (and scsi_cd) are now
exporting a device on their own, and use an I/O scheduler with an appropriate
DMA resource.
* There are still lots of TODOs, and it can easily panic - don't update if
you intend to demo Haiku.
* scsi_periph now only has an io() function that get an io_operation, instead
of the previous read/write functions, moved preferred CCB size from those
functions into the device registration.
* Changed all scsi_periph files to C++.
* scsi_cd ported, too, but untested.
* Removed block_io from image - it will be removed completely soon.
* Temporarily commented an ASSERT() in the ATA bus manager (in case you use
it); it's sometimes triggered by the code now, and I haven't yet looked into
the issue -- doesn't seem to harm, at least.

include the guard pages. Adjusted the kernel and boot loader code
accordingly -- the guard pages size is added/not removed respectively.
The stack size passed to _kern_spawn_thread() is now the actually usable
size, and it is no longer possible to specify a size smaller than or
equal to the guard pages size.
* vm_create_anonymous_area(): Precommit two pages maximum -- a stack with
only one page usable size obviously doesn't need two pages.

now a lot earlier.
* That makes it now possible to use modules pretty early in the kernel (like
before timer_init(), or int_init_post_vm()).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26790 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added file_map_set_mode() function that you can use to keep a whole file
cached. This is needed for the swap file support: FILE_MAP_CACHE_ALL will
not only precache all file_io_vecs when called, but it will also cause all
file_map_translate() calls to fail that would require further caching (ie.
if the file size had changed).
* Updated the fs_shell file map code to the latest one (with several bug fixes).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26785 a95241bf-73f2-0310-859d-f6bbb57e9c96
actual caching in the file cache, i.e. all reads and writes go directly
to the underlying device. The implementation is not quite complete,
since the VM can still add pages to the cache when the file is mmap()ed,
which can lead to inconsistencies.

and size of the double fault stack.
* is_kernel_stack_address() does now also check whether the given
address is on the double fault stack. This fixes stack traces on
double faults, which were broken (i.e. went only to the double fault
iframe) since we started checking whether the addresses are on the
kernel stack at all.

should really contain all permission bits.
* It now uses S_ISVTX instead of S_ISTXT - this is how it works in Linux as
well, while FreeBSD uses S_ISTXT there (but S_ISTXT and S_ISVTX have the
same value there, too).
* Also fixed the fs_shell this time.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26761 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Simplified the subpixel related methods for the AGG "pixel format" template
interface, the ones for the solid cover simply pass through the existing
methods, so only one subpixel blending function is left which does the actual
work (this removes a lot of the previously added code)
* Implemented a new rasterizer based on the original AGG rasterizer which
implements subpixel anti-aliasing for any generic AGG vector pipelines. It
is now optionally used in Painter and AGGTextRenderer (for vector fonts, ie
rotated, sheared or big enough fonts) depending on the global subpixel
setting.
* Put all subpixel variables into the new GlobalSubpixelSettings.h|cpp
* Simplified DesktopSettings related classes a bit and renamed previous
FontSubpixelAntialiasing to just SubpixelAntialiasing.
* The private libbe functions for subpixel related settings moved from Font.cpp
to InterfaceDefs.cpp where other such functions live. They are not related
to fonts only anymore.
* Removed the subpixel related settings again from the Fonts preflet and added
them to the Appearance preflet instead.
All of the above implements subpixel anti-aliasing on a global scale, which
to my knowledge no other OS is doing at the moment. Any vector rendering
can optionally use subpixel anti-aliasing in Haiku now. The bitmap cached fonts
are still affected by the Freetype complile time #define to enable the patented
subpixel rasterization (three times wide glyphs). Vector fonts and shapes are
not affected though at the moment.

when DUMP_FEATURE_STRING is defined to 1.

- Fixed deadlock in xsi_sem_undo - RecordUndo
- Fixed issue in xsi_sem_undo: if the semaphore set does not exist
anymore, ignore the request but do remove the process from the sUndoList,
which wasn't previously done.
- free() in ClearUndos was called with interrupts disabled
- when a semaphore set ends to exist, remove all it's sem_undo request as it's ID
will be reused in the future.

the environment would crash on Haiku. Added a small test application that
just checks every one of those.
* Fixed env locking (in userland, you better check against B_INTERRUPTED).
* Made our code safe against an environ of NULL.
* There is now an additional sManagedEnviron that points to the environment
our code actually managed; whenever an application overrides environ, we'll
get aware of it with the next *env() function invocation, and will handle
it adequately.
* Added non-POSIX clearenv() function.

reference.
* Changed put_vnode() to return an error in case the vnode couldn't be found.

partially (e.g. due to hitting the end of file). The respective
classes have grown new methods and attributes to deal with that. The
"finished" callbacks have got additional parameters to indicate
whether the transfer was only partial and how much has been
transferred. Other callbacks and functions have a size_t* in/out
parameter instead of a simple size_t, now.
* vfs_{read,write}_pages() do now use the I/O request framework instead
of the underlying FS's {read,write}_pages() hooks (those should be
unused now). Furthermore they've got an additional "flags" parameter,
which is passed to IORequest::Init(), i.e. it allows to specify that
the given vecs refer to physical addresses.
* The file cache's read_into_cache() reads directly into physical
pages, now.
* Fixed bug in DoIO::IO(): The offset was not adjusted, so that all
pages were incorrectly transferred from/to the same location.
* Fixed broken subrequest scheduling loop head in
do_iterative_fd_io_iterate().
* Adjusted the test driver and implemented its io() hook. Using this
driver I/O requests are passed all the way from the VFS/VM to the
driver and through the I/O scheduler. It even seems to work. :-)
* Added missing const to the iovec* parameter of the IORequest::Init()
methods.
* Disabled some debug output by default. Added new optional debug
output.

working when KDEBUG_RW_LOCK_DEBUG is defined to 1, the write assertion works
always.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26686 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added "syslog" command that dumps the contents of the syslog ring buffer into
KDL. Use the '-n' option to only show what hasn't been sent to the syslog
daemon yet.
* When entering the kernel debugger, the current thread ID and name are also
printed (not only the current CPU).

by myself:
* renamed xsi_do_undo() to xsi_sem_undo() (there is more to XSI than sems).
* Fixed coding style issues in sys/sem.h and xsi_sem.cpp.
* Added _kern_*() syscall prototypes to syscalls.h.
* Added a TODO in xsi_sem.cpp and xsi_semaphore.h about moving union semun to
a shared header.
* Made the team::xsi_sem_undo_requests int32 - due to padding, it would have
needed 4 bytes anyway; please always use specific types over int/short/long.
* xsi_sem_undo() now checks if it needs to do anything - the calls in team.cpp
no longer needs to do this.

const BBitmap* bitmap, BRect bitmapRect, BRect viewRect, uint32 options).
Only option so far is B_FILTER_BITMAP_BILINEAR.
* BView::DrawBitmap[Async](const BBitmap* bitmap, BRect viewRect) was accessing
the bitmap pointer without checking it. Would therefore crash when passing
NULL, unlike the other methods.
* The BPicture code already reserved room for the BBitmap flags, but did not
store the actual flags and neiter use them for anything. Since the bitmap
data is stored anyways, the bitmap creation flags do not matter. So I reused
this for the new bitmap drawing options.
* Rewrote Bitmap.h and removed the B_BITMAP_SCALE_BILINEAR flag again.
* Tried to optimize Painter::_DrawBitmapBilinearCopy32() a little by giving
the compiler better hints. There seems to be a marginal, possibly imagined
speed increase < 0.05 ms. ;-)

to provide asynchrounous (or only synchronous, if asynchronous is not
supported) I/O request support. It will eventually replace
{read,write}_pages(). None of the FS implementations implement them
yet.
* Implemented some support functions for request-based I/O. File system
implementations can use do_fd_io() which passes an I/O request to the
layer responsible for a given FD, and do_iterative_fd_io(), which
translates a request for a file to subrequests for the underlying
device and passes them on. Both fall back to synchrounous processing
when the io() hook is not supported.
Furthermore added vfs_synchronous_io() which should be handy for the
devfs to perform io_requests synchronously for devices that don't
support the io() hook.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26655 a95241bf-73f2-0310-859d-f6bbb57e9c96
* When drawing BBitmaps with scaling in the app_server, use a bilinear
filter when a bitmap has this flag set. (Hope nobody objects, otherwise
I can revert or improve this. Performance can certainly be improved, since
the AGG implementation is too generic. But that goes for the nearest
neighbor implementation as well.)
* Flags are uint32, fix app_server side code to declare them correctly. Use
appropriate link methods in BBitmap and ServerApp.
* Enable the BeOS compatibility mode for B_RGB32 (works just like B_RGBA32
in B_OP_ALPHA mode).

* Added "finished" callback to IORequest.
* IOOperation::Finish() no longer invokes its parent request's
ChunkFinished(). The finisher does this instead. ChunkFinished()
can optionally remove the chunk from the parent.
* Added IORequest::Wait() which waits for the completion of the request.
* Introduced IORequestChunk::ResetStatus() to make setting the status to
"pending" somewhat more explicit.
* Implemented the missing IOScheduler::SetCallback() methods.
* The NotifyAll() calls on the IOScheduler's condition variables were
missing, so it just waited forever.

It does its job by using part of libsupc++, with fake malloc and friends to make sure it won't double fault.
Works here, but cp-demangle must be extracted by hand from the lib, can't get the rule to work as I want, Ingo ?

introduces the following relevant changes:
* VMCache:
- Renamed vm_cache to VMCache, merged it with vm_store and made it a
C++ class with virtual methods (replacing the store operations).
Turned the different store implementations into subclasses.
- Introduced MergeStore() callback, changed semantics of Commit().
- Changed locking and referencing semantics. A reference can only be
acquired/released with the cache locked. An unreferenced cache is
deleted and a mergeable cache merged when it is unlocked. This
removes the "busy" state of a cache and simplifies the page fault
code.
* Added VMAnonymousCache, which will implement swap support (work by
Zhao Shuai). It is not integrated and used yet, though.
* Enabled the mutex/recursive lock holder asserts.
* Fixed DoublyLinkedList::Swap().
* Generalized the low memory handler to a low resource handler. And made
semaphores and reserved memory handled resources. Made
vm_try_resource_memory() optionally wait (with timeout), and used that
feature to reserve memory for areas.

though until we use ACPI for proper PCI IRQ routing through the IO APIC.
Therefore the IO APIC code path is not yet enabled and the IO APIC isn't used.
ISA interrupts would work though, as would PCI interrupts if you'd hardcode
them for your specific configuration.
Note that this change also modifies some parts in the bootloader and in the PIC
setup to make local APICs available even on non-SMP systems. This causes APIC
timers to be used instead the normal PIT if it is available (also on non-SMP
configurations).
Also fixes some general errors in SMP and PIC code as well as some code cleanup.

This allows drivers to lock the memory outside of the original team context.
* create_area_etc() got a struct team as first argument, but that should have
been a team_id.
* Removed delete_area_etc() - there is already vm_delete_area() doing the same

* Renamed vm_get_address_space_by_id() to vm_get_address_space(), as there is
no other method of getting an address space.

really makes no sense if the pointer belongs to the derived class and
only confuses). Note this change does not affect binary compatibility.
* Introduced a new MaxUpdateTextWidth() virtual method which is really
necessary to handle the update text correctly in the layout.
* Introduced a new UpdateTextChanged() method which can be called to
notify the control of a changed update text. Internally, SetValue()
also uses it.
* Handle the width or height of the UpdateText() correctly in the layout.
For horizontal layout, the width was forgotten to be included in
GetPreferredSize(), for vertical layout, it was completely broken before.
* Handle invalidation correctly when the UpdateText() changes.
* Remove the arbitrary insets for labels from the border the control. This
makes it easier to align the control's labels with other controls.

that specific volume) doesn't have one.

systems can get the partition they reside on easily.
* Updated TODO.

* adjust ui code to be more font sensitive
* add/ rename some of the utils message manipulation functions
* use ReadAttrString instead of ReadAttr to get the printer name

* rename private functions to use underscore
* rename some public functions to match the usual style
* adjust pdf/ preview driver to use the renamed functions
* we where leaking a single message in _ConstructGui, otherwise no functional change

struct sockaddr_in - the real culprits were BNetAddress::GetAddr(sockaddr_in&)
and BNetAddress::SetTo(const sockaddr_in&):
* moved check_r5_compatibility() into r5_compatibility.h to make that function
available to BNetAddress, too
* adjusted sockaddr_in-handling methods of BNetAddress to deal with R5-addresses
if in compatibility mode
* removed is_r5_sockaddr() again, since it is no longer needed
With this less hacky solution, Beam, NetPositive, NetworkTime and Vision still work. So, there's hope that the R5 compatibility layer is now complete.

disk system lists.
* Added module watching; on module changes, it will now automatically rescan
the disk systems.

* Extend the app_server protocol by configuration options to turn
subpixel font rendering on/off and also make the glyph hinting optional
(aligning of glyph shapes to the pixel grid).
* Implement the setting in the app_server and also handle the persistency.

* Prepared the AGG base_renderer code with two more functions needed to
handle subpixel scanline coverage values.

it clear when boot_splash_set_stage() must no longer be used.
* Free the memory associated with the kernel args before starting the
init process. Unlike the original TODO stated there are quite a few
more users of the kernel args (including the boot splash screen),
hence we can't really do that earlier, unless we decide to copy the
data over to the kernel heap.

when set, prevents any old mouse moved message discarding.
* BWindow::DispatchMessage(B_MOUSE_MOVED) checks the event time of the
message and discards too old events, but only if there is another event
in the queue and the view does not specify B_FULL_POINTER_HISTORY.
* BView::GetMouse() ignores the checkHistory flag passed to the function
in case the event mask specifies B_NO_POINTER_HISTORY.
B_FULL_POINTER_HISTORY on the other hand prevents the dropping of old
messages.

header.
* Added fields necessary to make it possible to retrieve more than one
dirent from the underlying file system.
* Unless some app creates a DIR on its own to it to feed readdir(), this
change should be binary compatible. If we find an application misbehaving,
we can still make it a GCC4 only thing.
* fs_attr/fs_index/fs_query now all use readdir() directly (as that one
contains the logic to iterate through a number of dirents in userspace).

It follows the semantics of the BFS R/W lock, though, that is, if you unlock
your write lock before the read locks, the read locks effectively become
write locks, too.
* Added a mutex_transfer_lock() function that will allow you to unlock a mutex
in a different thread than the one which locked it (only matters if KDEBUG
is enabled, though).

* fssh_auto_locker.h should probably better use an FS-Shell header instead of
stddef.h.

* Applied Korli's mutex_unlock() fix to block_cache.cpp.
* Removed block_cache_priv.h, as it's no longer needed (moved its definitions
into block_cache.cpp, as in the kernel file).
