/system/servers, now.
* Got rid of the dispatcher application. It was the entity the kernel module
talked to when mounting a yet unknown FS. It started the client FS server
applications. Now the kernel module starts them directly. They use
respectively named ports, so the kernel module can find them when already
running.

* The I/O context related vfs_*() functions have io_context* instead of void*
parameters/return values, now.
* vfs_new_io_context(): Lock the parent I/O context before getting its table
size. Otherwise the table size could change until we do.
* vfs_resize_fd_table(): Fixed use of MutexLocker. We created only a temporary
object, not one with function scope.
* Renamed load_image_etc() to load_image_internal() and added a parameter for
specifying the parent team of the one to create.
* Introduced a kernel private load_image_etc() with a few more arguments than
load_image().

* Split the FSCapabilities bit mask into three bit masks for the FS, the
volume, and the vnodes, since we have three independent FS interface
structures, now. The latter is not supported in the kernel add-on, yet.
* Server:
- Temporarily removed some things from the build (the BeOS interface
and the cache implementations).
- Some WIP in HaikuKernelVolume and [haiku_]kernel_emu.{h,cpp}.
- Added HaikuKernelNode, which wraps fs_vnode for the client FS.
The server is still quite a bit away from being buildable again.

* Extended the debugger message for B_DEBUGGER_MESSAGE_HANDED_OVER by the
causing thread.
* Also send B_DEBUGGER_MESSAGE_HANDED_OVER to the debugger to which the team
was handed over. The message will be the very first one the debugger gets
from the team in question.
* Some harmless refactoring (added thread_hit_serious_debug_event()).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29302 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added debugger commands to resolve usb_ids to pipes.
* Adjusted the physical memory allocator to be usable in a slimmed down mode
when running inside the kernel debugger.
* Implemented USB keyboard support for KDL through a kernel debugger add-on.
* Added kgetc() and made use of it where previously individual methods were used
to ensure that reading characters always goes through the kernel debugger
add-ons and the other methods.
This has some preconditions to meet though:
1) The keyboard must be in the boot protocol (currently the case but needs to
be revisited once we have a full usb_hid).
2) The keyboard must be attached to a UHCI root port (i.e. not use EHCI or OHCI,
also not through hubs unless those are USB 1.1).
3) the usb_hid driver has to be opened for this to work. This means that for the
time between initializing USB and when usb_hid is opened by the input_server
there is no keyboard support.
Also note that this has no way of detecting hot-plug, meaning that you can't
re-attach your USB keyboard from the hub to the root port once in KDL.
On the bright side of things, since this is a non-destructive mechanism it is
possible to enter and leave KDL without loosing the USB state.
Tested OK in QEMU, not tested on real hardware yet, will see in a few minutes.

the changes to the other filesystems.

It causes the interrupt handler to be inserted at the very end of the list
instead of at the top. It is intended to be used as a workaround when a
interrupt handler cannot know if it actually handled the interrupt. This
should never be used by native drivers. Also if we know that the result is
not valid because of this flag we won't disable the vector in case we count
many unhandled interrupts as those numbers are then unreliable.
* Moved B_NO_LOCK_VECTOR to be a private flag as well.
* Made the interrupt handler list a simple manually maintaned singly linked list
instead of the doubly linked one used with insque and remque as it greatly
simplifies things for such an easy use case and is more compact.

node. That is needed for a layered filesystem to be able to construct a full
fs_vnode out of a volume/inode pair.
* Adapt places where get_vnode is used. Sadly this is a C API and we can't just
use a default NULL for that argument.
* Introduce a flag B_VNODE_WANTS_OVERLAY_SUB_NODE that can be returned in the
flags field of a fs get_vnode call. A filesystem can use this flag to indicate
that it doesn't support the full set of fs features (attributes, write support)
and it'd like to have unsupported calls emulated by an overlay sub node.
* Add a perliminary overlay filesystem that emulates file attributes using files
on a filesystem where attributes aren't supported. It does currently only
support reading attributes/attribute directories though. All other calls are
just passed through to the super filesystem.
* Adjust places where a HAS_FS_CALL() is taken as a guarantee that the operation
is supported. For the overlay filesystem we may later return a B_UNSUPPORTED,
so make sure that in that case proper fallback options are taken.
* Make the iso9660 filesystem request overlay sub nodes. This can be fine tuned
later to only trigger where there are features on a CD that need emulation
at all.
If you happened to know the attribute file format and location you could build
an iso with read-only attribute support now. Note that this won't be enough to
get a bootable iso-only image as the query and index support is yet missing.

* Replaced the use of offsetof() for structs that aren't PODs. Add a
offset_of_member() macro to util/khash.h because that's what it's used for
in our cases.
* Change the signature of add_debugger_command()/remove_debugger_command() on
GCC > 2 to avoid the depricated conversion from string constants to char *.
* Adding some "suggested" parenthesis. I know that not everyone likes that, but
it pointed out at least one bug that is fixed here as well.

This is a very welcome addition.
* There are a few issues, and maybe questionable decisions (like the dependence
on ACPI), but I see no reason why it shouldn't be added in its current form
already.

not supported; will see if I can find a supported hardware, though.

old invalid user listeners yet, though (ie. if a team dies).
* Implemented userland network monitor functions.
* Added a few notifications to the network stack, even though this part isn't
complete yet (especially notify_interface_changed()).
* Added optional debug output to the notifications module.
* Added the module to the image, it basically works now (tested).

notifications are put into a separate module, so that the network stack can
be unloaded without losing connection, IOW user applications will continue
to retrieve notifications when the stack is loaded again.

* The DesktopSettings class is now using that to send the new
AS_SYSTEM_FONT_CHANGED message to all windows.
* The ServerWindow now propagates font changes to its decorator, causing it
to update its drawing. That means changing the bold font in the "Fonts"
preferences application will instantly change all window titles.
* Factored out a _RebuildAndRedrawAfterWindowChange() out of several Desktop
methods, simplifying some code.
* The DefaultDecorator no longer calls _DoLayout() twice (through SetLook()),
but instead calls the new _UpdateFont() method now also called by
FontsChanged(), and SetLook().
* BWindow::GetDecoratorSettings() now also includes "tab frame" BRect with the
exact footprint of the tab, allowing apps to know the size of the tab to
position itself accordingly.
* Automatic white space cleanup.

the per-root-image breadth-first sorted image array. Instead we have a
per-image hook function to resolve the symbols. The default function
uses the sLoadedImages list directly, which is breadth-first sorted
anyway. There's also a BeOS function for old-style symbol resolution
and one for add-ons, which lacks a proper implementation yet (just
uses old-style ATM).
* Made the dl*() functions POSIX compliant:
- dlopen() does no longer use load_add_on(), but loads the object as a
library. It also properly supports a NULL name, now -- the previous
"_APP_" work-around did only work, if this soname was set on the
program (unlikely for programs using this API).
- Implemented RTLD_{GLOBAL,LOCAL}.
- dlsym() looks up symbols properly now, i.e. not just in the given
image, but breadth-first for an actual image or in load order for
the global scope. It also supports the not-quite POSIX RTLD_DEFAULT
and RTLD_NEXT extensions. Our RTLD_NEXT finds more symbols than in
Linux (also in later dlopen()ed libraries), but that should be fine.

gWidthBuffer.
* Tracker PoseView now uses BPrivate::gWidthBuffer instead of it's own
instance.
* TextView.h and PoseView.h are now a little cleaner.
* InterfaceDefs.cpp now deletes gWidthBuffer in _fini_interface_kit_().
* Added binary compatibility support for NetPositive in WidthBuffer.h and .cpp.
Obviously it kind of defeats the purpose of having WidthBuffer neatly tucked
away in the BPrivate namespace, but Haiku should run NetPositive, I guess.

This is not necessary, since userland teams' page directories also
contain the kernel mappings, and avoids unnecessary TLB flushes. To make
that possible the vm_translation_map_arch_info objects are reference

scheduler_set_thread_priority(). Setting the thread priority was the
only situation in which it was used.
* Renamed scheduler.cpp to scheduler_simple.cpp.
* The scheduler functions are no longer called directly. Instead there's
an operation vector now, which is initialized at kernel init time.
This allows for picking the most suitable scheduler for the machine

added vm_memcpy_from_physical() and vm_memcpy_physical_page(), and
added respective functions to the vm_translation_map operations. The
architecture specific implementation can now decide how to implement
them most efficiently. Added generic implementations that can be used,
though.
* Changed vm_{get,put}_physical_page(). The former no longer accepts
flags (the only flag PHYSICAL_PAGE_DONT_WAIT wasn't needed anymore).
Instead it returns an implementation-specific handle that has to be
passed to the latter. Added vm_{get,put}_physical_page_current_cpu()
and *_debug() variants, that work only for the current CPU,
respectively when in the kernel debugger. Also adjusted the
vm_translation_map operations accordingly.
* Made consequent use of the physical memory operations in the source
tree.
* Also adjusted the m68k and ppc implementations with respect to the
vm_translation_map operation changes, but they are probably broken,
nevertheless.
* For x86 the generic physical page mapper isn't used anymore. It is
suboptimal in any case. For systems with small memory it is too much
overhead, since one can just map the complete physical memory (that's
not done yet, though). For systems with large memory it counteracts
the VM strategy to reuse the least recently used pages. Since those
pages will most likely not be mapped by the page mapper anymore, it
will keep remapping chunks. This was also the reason why building
Haiku in Haiku was significantly faster with only 256 MB RAM (since
that much could be kept mapped all the time).
Now we're using a different strategy: We have small pools of virtual
page slots per CPU that are used for the physical page operations
(memset_physical(), memcpy_*_physical()) with CPU-pinned thread.
Furthermore we have four slots per translation map, which are used to
map page tables.
These changes speed up the Haiku image build in Haiku significantly. On
my Core2 Duo 2.2 GHz 2 GB machine about 40% to 20 min 40 s (KDEBUG
disabled, block cache debug disabled). Still more than factor 3 slower
than FreeBSD and Linux, though.

* Introduced flag "invoke_scheduler" in the per CPU structure. It is
evaluated in hardware_interrupt() (x86 only ATM).
* Introduced SMP_MSG_RESCHEDULE_IF_IDLE message, which enters the
scheduler when the CPU currently runs an idle thread.
* Don't do dprintf() "CPU x halted!" when handling a SMP_MSG_CPU_HALT
ICI message. It uses nested spinlocks and could thus potentially
deadlock itself (acquire_spinlock() processes ICI messages, so it
could already hold one of the locks). This is a pretty likely scenario
on machines with more than two CPUs, but is also possible when the
panic()ing thread holds the threads spinlock. Probably fixes#2572.
* Reworked the way the kernel debugger is entered and added a "cpu"
command that allows switching the CPU once in KDL. It is thus possible
to get a stack trace of the thread not on the panic()ing CPU.
* When a thread is added to the run queue, we do now check, if another
CPU is idle and ask it to reschedule, if it is. Before this change, the
CPU was continuing to idle until the quantum of the idle thread
expired. Speeds up the libbe.so build about 8% on my machine (haven't
tested the full Haiku image build yet).
* When spinlock debugging is enabled (DEBUG_SPINLOCKS) we also record
the spinlock acquirer on non-smp machines. Added "spinlock" debugger
command to get the info.
* Added debugger commands "ici" and "ici_message", printing info on
pending ICI message respectively on a given one.
* Process not only a single ICI message in acquire_spinlock() and other
places, but all pending ones.
* Also process ICI messages when waiting for a free one -- avoids a
potential deadlock.
* Mask out non-existing CPUs in send_multicast_ici(). panic() instead of
just returning when there's no target CPU left.

* Fixed a general problem with respect to overriding of the reserved
virtual function slots: instead of statically invoking the method
that corresponds to the reserved slot on the class that contains the
slot, we now invoke the virtual Perform() method. Perform() then dispatches
the method invocation to the "proper" class, i.e. the highest class in the
hierarchy that actually implements the requested method.
This fixes a crash in apps that use liblayout's MSlider class and
should fix one or other spurious bug with old apps or libraries, too.
* added new header folder 'binary_compatibility' that contains files that
define the method codes and data structures required by Perform()
* looked for and implemented all used reserved virtual slot functions to
invoke Perform() where necessary or to pass on the method call statically
(for slots that were already maintained by Be)

* Implemented BGradient, BGradientLinear, BGradientRadial,
BGradientDiamond, BGradientConic and BGradientRadialFocus
new Interface Kit classes.
* Implemented all the (AGG-based) backend necessary in
the app_server to render gradients (Painter, DrawingEngine)
* app_server/View can convert a BGradient layout to screen
coordinates.
* Added BGradient methods of the Fill* methods in BView.
* Implemented a test app and added it to the image as a
demo.
* Adopted Icon-O-Matic and libs/icon in order to avoid
clashing with the new BGradient class. Re-use some
parts where possible.
Awesome work, Artur! Thanks a lot. Now a more modern
looking GUI has just become much easier to implement! :-)
TODO:

in struct stat.
* Instead, I followed Marcus' great idea and added a compatibility check in
the runtime loader: now, R5 binaries (also shared libraries) are detected,
and they get special versions for stat(), fstat(), and lstat() that return
the smaller stat struct.
* However, I've disabled (in src/system/libroot/posix/sys/stat.c) using the
larger stat field for now, as this breaks some of our optional packages.
So until we rebuild them all, this shouldn't be enabled.
* This should now also be used for BeOS compatibility in libnetwork.so.

arch_vm_aspace_swap().
* The x86 implementation does now maintain a bit mask per
vm_translation_map_arch_info indicating on which CPUs the address
space is active. This allows flush_tmap() to avoid ICI for user
address spaces when the team isn't currently running on any other CPU.
In this context ICI is relatively expensive, particularly since we map
most pages via vm_map_page() and therefore invoke flush_tmap() pretty
much for every single page.
This optimization speeds up a "hello world" compilation about 20% on
my machine (KDEBUG turned off, freshly booted), but interestingly it
has virtually no effect on the "-j2" haiku build time.

buffer format, the buffer can now also contain other events than just
stack traces. ATM these are only references to the image events
(created/deleted). Therefore we no longer have to flush the profiling
buffer after such an event, since the debugger can exactly match the
samples. Since we couldn't flush when the profiling timer hit while the
thread was in the kernel, that wasn't working that well anyway.
"profile -f" fails to translate stack trace addresses only very rarely,
now.

been mounted, before anyone could try to load any modules from it.
Also pass it a flag whether the boot volume is where the boot loader
pre-loaded the modules from.
* module_init_post_boot_device() changes the pre-loaded module image
paths to normalized boot volume paths, now. Got rid of the code in
register_preloaded_module_image() which tried something like this.
* Changed module image ref counting. A referenced module has single
reference to its image, which is released when the module becomes
unreferenced.
* get_module() for a reference module will not try to re-get and re-set
the module's image anymore. That could lead to a similar module (from
different paths) being loaded at the same time. A module from a new
file can only be loaded when the old one has been put completely.
* Simplified B_KEEP_ALIVE module handling a bit. When the module is
initialized, we add another reference, which we'll never free. Thus
the module remains loaded without special handling. Removed
module_image::keep_loaded. A B_KEEP_ALIVE module remains referenced
and thus its image remains referenced, too.
* Removed module::file, a cached path to the module's image. An
optimization that wouldn't work with multiple root directories for
modules (/boot/beos/..., /boot/common/...) or when module files were
moved. get_module() does now always search the image file, when the
module is still unreferenced. This should be a bit slower than before,
but I didn't notice any difference in VMware at least. If it turns out
to be a problem we could introduce a more intelligent cache that stays
up to date by using node monitoring.

* Extended the profiling API by an option to record a variable number of
samples per tick. The stack depth is used as a maximum.
* Added new option "-f" to the "profile" tool. When specified it
increments the hit counts of all symbols in the full available caller
stack. I.e. the resulting hit counts will approximate the total time
spent in each function or any function directly or indirectly called
by it. Thus "_start" and "main" will usually get 100% and leaf
functions only what time has actually been spent in them.

buffer during a timer event that interrupted a kernel function: We do
now flush the buffer as soon as it is 70% full, *if* we didn't interrupt
a kernel function. When the buffer runs full and we still haven't hit a
user function, we drop the tick. The number of dropped ticks is recorded
and sent to the debugger with the next update message.
Reverted the previous partial solution (the temporary disabling of
profiling while in debugger support code).

sent with several debugger messages.
* Track the image event counter that is used when samples are added to
the profiling buffer. If the current team counter differs, we flush
the buffer first (sending an update message to the debugger), so that
the debugger has a chance to match the addresses to the correct images.
* Disable profiling for a thread while it runs in the debugger support
code. This fixes potential deadlocks which could occur when a
profiling timer event occurred that would require the buffer to be
flushed while the thread was just sending something to the debugger or
waiting for a command. As it turns out, this is not sufficient either,
since we should never try to flush the buffer when the timer event
occurred in the kernel, since the thread might hold a lock that the
debugger thread could try to acquire. Will implement a more general
solution later.

BTextView classes:
* Declared the directly used BTextView helper classes as private BTextView
classes and changed all affected files.
* Realized that Tracker's BPoseView was (accidentally?) using what used to
be _BWidthBuffer_. It had declared it's own class with the same name and
same members/size in headers/private/tracker/TextViewSupport.h, but the
implementation was nowhere to be found. I can only explain this that
the BTextView implementation was then actually linked and used. But the big
problem was that it was used without locking (unlike in BTextView)! When
many Tracker windows opened during system startup or later and they happened
to each request characters not yet in the cache, I imagine things could have
gone bad and corrupted memory. Anyways, since I can see the usefulness of
the cache, BPoseView uses BTextView::WidthBuffer on purpose now. And I moved
the locking inside BTextView::WidthBuffer::StringWidth().
* Adjusted InterfaceDefs.cpp accordingly.
* TODO: Move subsequent classes into BTextView namespace as well, ie derived
classes that BTextView doesn't directly know about. All stuff in src/kits/
inteface/textview_support/
* Added preliminary and not yet implemented layout friendly BTextView
constructors.
* I will try to handle the insets imposed by BTextView::fTextRect a bit
differently when used inside the new layout management framework. For this,
I added BTextView::SetInsets() and GetInsets(). SetInsets() doesn't do
anything yet.
So far, everything seems to work still... ;-)

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).

* 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.

of range if I understand the ticket right.
Thanks a lot, David, and sorry it took so very long to apply your patch!

Powel. The functionality was written by Jeff Prosise and Davide Pizzolato and
has been cleaned up and adopted to the Haiku coding style by David Powell and
myself. The class can perform a color quantization for generating the optimal
color index palette (with given maximum size) from a given RGBA image.

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.

* The "in_context" command does now set the currently debugged thread
respectively.

debug_{get,set}_debugged_thread(). By default the currently debugged
thread is the thread that dropped into the kernel debugger, but commands
like "in_context" can change it.

mainly supposed to be used for resizing allocations asynchrounously.

don't wait for memory or pages to become available. They fail
immediately instead.

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).

given only the allocation for the specified heap are considered.

be passed on to the IORequest. Most relevantly physical pages can now
be written directly by passing B_PHYSICAL_IO_REQUEST.
* Added VMCache::WriteAsync() which is supposed to write pages
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
scheduler reorders I/O operations.

- 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.
* Added get_device_icon(), BPartition::GetIcon(), and BVolume::GetIcon()
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.
* Tracker's MountMenu class now uses B_RGBA32 icons, instead of B_CMAP8.
* Added vector icon to scsi_disk, and scsi_cd. The former doesn't have any
special removable icon, though.
* Header cleanup, added/updated license, whitespace cleanup.
* Marked deprecated/obsolete driver ioctls in Drivers.h.
* Removed OpenBeOS namespace in the headers I touched that still had them.

Ingo suggestions: instead of having one global sem_undo list,
we now have two local list, one per semaphore set and one per team
which is held in its xsi_sem_context structure, along with a mutex.
A mutex has also been added to the semaphore set class in order to
protect the local list, but also in order to (hopefully) improve
concurrency.

wait_for_timer() function.
* Moved the internal Fifo class into utility.cpp - we should probably just
remove it again.
* Fixed uninit_timers() so that it would even work in combination with the
timer thread if there are timers left to be scheduled.
* Minor cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26980 a95241bf-73f2-0310-859d-f6bbb57e9c96
our dma_restrictions structure (but we're using blocks instead of bytes,
since unlike the block size, the restrictions attributes are constant).
* We might want to use blocks for the dma_restrictions structure as well in
the future...
* Fixed another bug in the device_node variant of DMAResource::Init(): the max
segment size was specified in blocks as well.
* Removed the "hardcode" block_io module and header.

* Made heap_class, heap_create_allocator(), heap_memalign(), heap_free()
public, so that a specialized allocator can be used elsewhere in the
kernel.

return 0x4.

get_window_order() will retrieve the application respectively window order
on the selected workspace.
* Moved private BeOS compatible functions (as used by the Deskbar) into the
private WindowInfo.h header.
* Whitespace cleanup.

* 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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26819 a95241bf-73f2-0310-859d-f6bbb57e9c96

* 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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26775 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.

- 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.

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.

* Added ASSERT_{READ|WRITE}_LOCKED_RW_LOCK() macros. The read assertion is only
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.

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.

- Fix PincodeWindow to send the pincode commands dissapear after clicking
- Improve the debug output of bluetooth_server
- Handle all needed events for the pairing
- Simple request could send and receive the event before adding the request to the events wanted list. Inverted the order of this sequence.

- rewrote early_query() to use the TT0 mapping to remove the page_hole stuff.
- fixed natfeat, using a page set up from the bootloader for now as it wants physical address. At least it's enough to see from the debugger:

* As this was the last user of the READ_COUNT/WRITE_COUNT definitions in
vm_priv.h, I removed those as well.

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 ?
Maybe using it directly without malloc hack would be ok with 16KB buffer, but I'm not sure of that.

fs_vnode_ops::write_pages() to be called with fsReenter = true. Since
this is no longer the case, the argument has become superfluous. For
read_pages() it always was. Removed the argument from the functions
and all functions that propagated it.
* Some whitespace at the end of lines was removed.

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.

* move libprint headers into libs headers folder accordingly
* merge all shared folders sources into kits print, we might build later on a
real print kit, propably also to access cups from an nicely API, atm static
* move all shared headers into private print, also pr_server.h from interface
* adjust build to work with the changed folder layout

bootloader's smp init and into its own unit.
ACPI tables can now generally be found with acpi_find_table(signature).

- bitfield definitions of page dirs were reversed... 040 is still wrong though.

- move part of mmu handling to mmu-dependant files and extend ops
- implemented 040 mmu init. doing so I spotted a bug in ARAnyM which ignored [ID]TT0. Linux likely doesn't use them but I was too lazy touse temporary page tables. I also noticed bitfields were in wrong order, to be fixed.

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

* Removed the superfluous "flags" parameter from ConditionVariable::Add()
that we forgot there when we moved the flags field from
ConditionVariableEntry::Add() to Wait().
* Using this method was therefore not a good idea - only UnixFifo did, though.

* 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.

* 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.
