and defines the macros needed by them.
* Renamed syscall sys_vm_map_file() to _kern_map_file() and changed the
path to an FD parameter. Changed vm_map_file() accordingly and
adjusted the kernel ELF loader and the runtime loader.
* Added syscall _kern_unmap_memory().
* Added bool unmapAddressRange parameter to vm_create_anonymous_area()
and map_backing_store(). If true and the address specification is
B_EXACT_ADDRESS, all areas in the specified address range will be
deleted (unless an area is covered only partially).
* Introduced B_SHARED_AREA flag, which is set on areas that have been
created by {vm,_user}_map_file() with REGION_NO_PRIVATE_MAP. When
fork()ing those areas won't be copied CoW, but rather be cloned. This
is needed for mmap() MAP_SHARED.
* {vm,_user}_map_file() also accept an FD argument < 0, in which case an
anonymous area is created.
* Implemented mmap() and munmap(). Currently there's the restriction
that we can't partially unmap areas. Otherwise the functions should be
rather compliant. We also support the non-POSIX extension
MAP_ANONYMOUS.

net_buffer and for processing received ancillary data. Not sure, if that
is flexible enough for all kinds of ancillary data, but it is for

implement one of those) -- don't know any other types on other protocol

reason to check the flag at all, since we know we set it.

ATM.
* Changed common_fcntl() to also work for non-vnode-based FDs. Only the
operations that require a vnode do fail now. F_SETFL uses the new
fd_ops::set_flags() if available, falling back to the vnode respective
operation.
* Changed some direct accesses to file_descriptor::u::vnode. It was safe
in those cases, but might not be anymore if we ever change fd_vnode().
ftp can at least connect to servers again, now, but apparently we still
have a problem with syscall restarts -- downloads fail after one second,
when the timer goes off.

syscall_restart_ioctl_is_restarted() to syscall_restart_is_restarted,
IoctlSyscallFlagUnsetter to SyscallFlagUnsetter, and
IoctlSyscallRestartWrapper to SyscallRestartWrapper, as they are no
longer only used for ioctl().
* Removed unused syscall_restart_ioctl_handle_post().
* Made SyscallRestartWrapper a lot fancier. Instead of storing a
reference to the result value, it stores the value itself, and it
features all the interesting operators that make it appear like that
value. This simplifies the use of the class quite a bit.
* THREAD_FLAGS_SYSCALL is now set for all socket function and the
read[v](), write[v]() syscalls.
* Added is_syscall() function and net_stack hook to the net stack.
* Removed "kernel" parameter from all net_stack_interface and net_socket
module hooks. They aren't need any longer, since is_syscall() can be
used instead.

- The net_stack driver is no longer used. Instead we have a kernel
module which is directly used by syscall implementations in the
kernel. I.e. we no longer tunnel those functions through ioctls, but
have normal syscalls.
- Removed the superfluous net starter module.
- Implemented the FDTYPE_SOCKET type file_descriptors, that is sockets
are no longer vnode based.
- Adjusted libnetwork (the socket function implementations)
accordingly.
- Adjusted netstat accordingly.
* Socket module:
- Implemented socketpair().
- Added "kernel" parameter to the control hook. Quite a few more hooks
would actually need the parameter, but I didn't change those yet,
since that would probably also require changes to the protocol
module interface.

between the header and the (one) class. If someone has a better fitting name

Separated the usb_raw.h into usb_raw.h which defines the protocol and
usb_raw_private.h which holds the internal device structure for usb_raw. This
reduces the header dependencies.

- Moved most file_system_module_info hooks into separate structures.
Those that operate on mounted volumes to fs_volume_ops, those
operating on a vnode to fs_vnode_ops.
- Got rid of the fs_volume, fs_cookie, fs_vnode typedefs. We use void*
again.
- Instead of a void* volume and node cookie hooks are passed a
fs_volume and fs_vnode structure pointer, which contain the cookie
and an ops pointer (fs_volume a few more things).
- The VFS {new,publish,get,...}_vnode() functions take a fs_volume*
instead of the volume ID. So does vfs_get_fs_node_from_path().
- Added type and flags arguments to publish_vnode() and the
get_vnode() hook and removed the type argument from lookup() hook.
Added vnode::type using formerly unused bits to store the node type.
Simplified a few things in the VFS due to the now always available
node type.
- Added fs_volume_ops::{create,delete}_sub_vnode() and
fs_vnode_ops::get_super_vnode() hooks. They are used to support file
system layers, e.g. allowing to extend an FS not supporting BeOS
attribute with attribute support. Needs some more work in the VFS.
- Added fs_vnode_ops::create_special_node() hook for creating special
nodes (e.g. FIFOs).
* Adjusted the built-in file systems and BFS according to the interface
changes. Removed all other FSs from the image for the time being.
We'll see whether further API changes are necessary before porting
them.
* Adjusted the bfs_shell accordingly.
* Implemented create_special_node() in rootfs to support special nodes.
* Added support for FIFOs:
- Added syscall _kern_create_fifo() (used by mkfifo()), which creates
a special node (type S_IFIFO) in the respective file system.
- When a special node is published the VFS creates a respective sub
node. Currently only FIFOs are supported.
- Added a little support for FIFO subnodes by using functionality from
the pipefs.
- Added mkfifo to the image. It can create FIFOs in the rootfs, but
the FIFOs aren't really usable ATM, since they still work like
pipes, i.e. readers and writers need to have them open at the same
time.
* Some smaller changes in the VFS:
- Made the *_CALL macros nicer to use (vargs).
- Refactored FS entry lookup into new function lookup_dir_entry().
- create_vnode() no longer just calls the FS create() hook. First it
looks up the entry and uses open_vnode(), if it already exists. This
is necessary for two reasons: 1) The FS might not support create()
while still allowing to open() entries. 2) When the FS has other
layers on to of it (or the respective node) it might not be
responsible for opening the node.

* Implemented RLE compression for the boot splash images, resulting in
smaller kernel and boot loader.
* Only the boot loader contains the RLE compressed images, the decompressed
buffer for the icons is passed to the kernel via kernel args.

The dividing line is back although with a little more spacing. Also the icon
spacing is a little increased and I added a subtle outline as well as a little
brighter background for the active icon look. The placement logic is now not
independant of each other anymore, otherwise I couldn't center both images
as a unit. But only the vertical placement is affected.

* Added {Create|Delete}Device() analogous to {Create|Delete}FileDevice
* Added a small DeviceWatcher class that reacts to entry creation/removal
* Implemented a way to start/stop node monitoring
* Start watching for devices after the boot volume has been mounted and the
the second initial scan was run
The disk device manager now creates and scans a device when a "raw" node is
published and deletes the device on removal. This makes hot-plugging of disk
devices (for example memory sticks using usb_disk) work. Their partitions will
be scanned and published so they can be mounted. Somehow the removal of the
partitions does not yet work however, any insights are welcome.

* The boot loader and kernel now use the placement info that
generate_boot_screen now generates.
* Made the code that draws the images handle the case where any of the images
is larger than the frame buffer.
* All drawing functions need to know the image width (analogous for bytes per
row).

* Added quasi-standard getpwent_r() and getgrent_r().
* Added _SC_GETGR_R_SIZE_MAX and _SC_GETPW_R_SIZE_MAX sysconf()

* Moved initgroups() and getgrouplist() definition to grp.cpp. They use
the same backend as the <grp.h> functions.
* Set the permissions of files created by the build system to what they
should be on the image (executables: 755, others: 644). Otherwise only
root could do anything under Haiku.
* Added build system variables HAIKU_ROOT_USER_NAME and
HAIKU_ROOT_USER_REAL_NAME to customize name and real name of Haiku's
root user.
* Added build system rules AddUserToHaikuImage and AddGroupToHaikuImage
for adding additional users and groups (by default only root user and
group and a "users" group are created).
* Adjusted BIND port and coreutils config.h files according to what
features have become available.
* Fixed HAIKU_DOCUMENTATION_OBJECT_DIR definition. Untested, but it used
a wrong variable name before.

* The bios_ia32 video platform code now stores the available VESA modes in
the new vesa_modes kernel_args field.
* When configuring a VESA mode via settings file, it's no longer needed to
specify the exact mode - the closest available mode is now used. This should
help with bug #1962.
* frame_buffer_console_init() now also creates a boot_item for the VESA modes
in the kernel_args.
* The VESA accelerant now filters the mode list to only contain modes that
are actually supported.

- Added a "root" vnode to the io_context. It is used for resolving
paths and converting nodes to paths instead of sRoot. Some more
passing around of io_context structures was necessary.
- Introduced a new lock sIOContextRootLock to protect
io_context::root. The current uses of io_context::io_mutex
(put_vnode(), remove_vnode() while holding it) looked too suspicious
to use that mutex in vnode_path_to_vnode().
- Added _kern_change_root() syscall and chroot() libroot function.
- Added chroot coreutils program to the image. Funnily it seems to be
much easier to set up a little jail than under Linux (just copy
bash and libroot.so into respective subdirs; mount another pipefs
if you want pipe support).
With Haiku allowing direct access to directories via inode IDs
jailing is obviously not very secure at the moment.
- Added /var/empty to the image. It will be the chroot target for ssh.
* Changed vfs.cpp:get_cwd() so that the io_context::io_mutex is no
longer held when calling dir_vnode_to_path().

* Implemented BFileInterface class which was nearly empty so far. Added handling of messages passed to BFileInterface class.
* Added needed structs and message values to DataExchange.
* This is needed to get for instance the reader.media_addon to work. Usually one calls above functions to set a file to be decoded by the node. If the target is a consumer, they are used for setting the target for encoding data.

- The kernel stores the group IDs in the team structure. They are
correctly inherited on fork() and load_image_etc().
- Implemented getgroups() for real, i.e. it retrieves the groups
associated with the process.
- Implemented setgroups(), initgroups() and (the BSDish)
getgrouplist(). The latter two read the group information from the
"group database" /etc/group (if existing).
- Change the BIND port config, since we do have getgrouplist() now.
* The set-uid feature was broken when the path to the executable was
relative, since we used stat(), which, in the kernel, uses the kernel
IO context.

* implemented BControllable::StartControlPanel(). The behaviour is supposed to be the one documented in the BeBook, meaning that it first checks if the BControllable node has been instantiated over an BMediaAddOn. If so, we investigate where the addon is located and try to launch it. Thus media_addons which have a control panel need to be compiled as an Application, not as an Addon. See r24664 as an example.
* inside BControllable::HandleMessage() call StartControlPanel for the message.

finally created a solution to avoid that: Header files that contain
configuration settings (and nothing else) go to build/config_headers.
To change settings, create a directory build/user_config_headers (which
is ignored by svn), copy the respective header there and modify it at
your leisure. Currently only tracing_config.h has been moved to the new
location, but more files will follow eventually. It is also recommended
to move optional macro definitions in Jamfile (as for BFS) to a config
header instead; the build system will then automatically rebuild on
changes.

file system to not fill newly created space with zeros.
BFile::SetSize() now uses this, while [f]truncate() does not. This
is only a temporary work-around until BFS supports sparse files.
* Apps that want to reserve space to fill up later should use
BFile::SetSize() for now, as this will be a lot faster than
[f]truncate().
* cache_io() and the functions below now use a special mode when you
pass in a NULL buffer: for read access, the cache is only populated
(useful for prefetching), for write access, the file is filled with
zeros.

shared object to find out the GCC version it has been compiled with.
This is not an exact science, since we've got the version string for
every single object file that has been linked in, but my heuristic seems
to be good enough.
Having the gcc version at hand will allow for two features: Enabling
work-arounds for old executables (like the type info problem in BeOS
apps), and automatically selecting the right set of libraries in a mixed
gcc 2/gcc 4 environment.

but operates "read-only".
* Added FindKeyFrame() method to ReaderPlugin, see above.
* Reformated ReaderPlugin header. Added const qualifier to Source() method.
* Small cleanups in BMediaTrack::SeekToTime() and SeekToFrame(). Added TODOs
with regards to "seeking" in decoders, wich should IMHO be revised. (Codecs
cannot seek in the stream, they only get fed chunk data. The only thing they
can do is reset themselves in preparation for a discontinuity of the chunk
data...)
* Implemented BMediaTrack::FindKeyframeByXX() methods via the new
MediaExtractor::FindKeyFrame() method.
* Implemented Seek() and FindKeyFrame() methods in the Reader base class,
returning B_NOT_SUPPORTED. I think this makes sense and also I don't have
to adapt all existing Reader plugins for the new FindKeyFrame() call. :-)
* Implemeneted FindKeyFrame() in the avi_reader. The OpenDMLFile class
gets Seek() extended for a "read-only" mode. Currently the implementation
is broken (as before) with regards to keyframes. These were ignored before
and I have not changed them to actually support the seek flags with regards
to keyframes. That's the interesting TODO...
* Some reformatting here and there in avi_reader code, sorry for the mixup.
The only actual change is the support for the read-only flag to Seek().

* The boot splash code now checks wether debug screen output is enabled or not
using the above function.
* The boot splash code no longer maps it's own copy of the frame buffer, instead,
it will use the boot item feature as the VESA driver does. Also removed the
lock, as that's not needed at all.
* Renamed splash.cpp to boot_splash.cpp, and boot/splash.h to boot_splash.h
(it's not part of the boot loader, but the kernel).
* Removed dead code from boot_splash.cpp, added license. Replaced license
header in boot_splash.h to a style guide conforming one.

* Added Artur to the contributors list in About System.
* Fixed some left overs in the patch, kept tracing turned off.
TODO:

those from hsbg and put them into images.h? Have user provide icon
spacing/offsets at the command line for hsbg?)
* Rename the stages to something meaningful.
* Use hsbg as a build system tool and generate images.h during build
from PNGs provided in the artwork folder.

tested on BeOS.
* Removed stddef.h and stdarg.h. They are provided by the compiler.
* Adjusted size_t.h, wchar_t.h, and wchar.h accordingly.
* Made stdio.h avoid gcc 2.95.3's fixincludes hack stdio_va_list
* Added gcc 2.95.3 headers to the repository. They are used instead of
the headers of the gcc 2.95.3's we use to compile Haiku with. Should
avoid build problems with the BeOS native compiler.
For sake of personal recreation you can rebuild the cross gcc 2.95.3,
but the only thing that changed is its header directory
(lib/gcc-lib/.../include), which isn't used anymore. Replacing it with
headers/build/gcc-2.95.3 should have the same effect as rebuilding, BTW.

* Adjusted size_t.h, wchar_t.h, wchar.h accordingly. This should fix the
annoying "ssize_t redefined" warnings when compiling under Haiku.
* When building Haiku the gcc headers come first in the include
search path now, as it should be. The respective TODO suggested that
this might break the build depending on compiler version and host
platform. I've tested with Linux gcc 2 and gcc 4, which work fine.

still initializes it to 1. As Karsten pointed out, this is necessary to
preserve the "shareable" status of the private data.

the objective function summands are now stored using class Summand.
* Some method names are more BeOS compliant now: SetX instead of ChangeX.
* linprog test code now uses new AddConstraint methods.
* CalculateMinSize and CalculateMaxSize did not free the memory they
allocated.
* Removed inappropriate setter and getter methods.
* Memory allocated in class Constraint is freed now.

_ReplaceAtPositions(), and _DoCharacterEscape() (we don't need to preserve
it, though, as it must be 1).
* Factored out an _Alloc() method which is now always called when the private
data is allocated. It also takes care of correct initialization (and thus
fixes the above problem).
* This fix finally allows turning on reference counting again, thanks Karsten!
* Minor cleanup, renamed "oldAdr"/"newAdr" to "oldString", resp. "newString".

* Since that caused troubles (NetPositive now crashes when started), I
temporarily disabled references by letting _IsShareable() always return
false until the issue is resolved.
* _FreePrivateData() now sets the fPrivateData member to NULL, and is also
safe to be called when fPrivateData is NULL.
* Removed my comment about the threading problem in _Detach() and _DetachWith()
as that just couldn't happen.
* _Clone() must not use memcpy() as the string pointed to by "data" might not
be as long as "length".
* LockBuffer() now marks a string as unshareable.
* Minor cleanup.

the new sematic of transfer_area so a message area is transfered into the right
teams' address space and it does not need to be cloned there anymore. Passing
by area is only used for messages bigger than a certain size (currently
hardcoded to 40KB) which should be somehow bound to the max port message size.
This makes passing large messages (i.e. > the port limit) possible, so for
example copy&paste of long text, image data, etc. should now work.
Got rid of the fClonedArea member as it is not necessary with the new design,
renamed shared_area to message_area in the private message_header, avoid
an unnecessary allocation of the header for the copy constructors, check
allocations in a few more places and some minor cleanup.

transfering the area, the area is cloned into the target teams' address space
and the original is deleted. This generates a new area_id for the transfered
area (as suggested by the ToDo). Updated syscall prototypes according to the
status_t to area_id return type change.

- Major cleanup of Appearance prefs - colors are now dynamically
read from the app_server, and updating them also works, but
triggers a bug: the state of the current window somehow gets
confused, i.e. if I update the panel background color, for some
reason the color of the BButtons in the appearance pref change color
and also the textviews begin misbehaving. Have not yet tracked down
the cause of this, but newly created windows after making the change
do show up with the updated color and behave properly. Also vastly
simplified the pref and cleaned up some obsolete definitions.

* Corrected comment
This function is used by the app_server to convert the UTF8 strings to char
codes to feed FreeType. Using a non space substitute character at least for
now, as it makes it more obvious where invalid characters are present.
I tested this change with some UTF8 test files and it seems to work well.

still inside the same UTF8 glyph. I cannot really tell, I am hoping you don't

* Added new devfs_driver_added(), and devfs_driver_removed() functions
that trigger certain driver actions.
* Implemented notifying devfs on B_ENTRY_CREATED, B_ENTRY_REMOVED, and
B_ENTRY_MOVED events in probe.cpp. The watched directory inode numbers
are now stored in a hash for B_ENTRY_MOVED.
* unpublish_driver() did not actually delete the node, it only marked

* Renaming things in Tracker list mode no longer magically grows the text view.
* ScrollToOffset() is not supposed to depend on the existence of any scroll
bars, in R5 text views simply scroll to where they need to. This fixes
renaming things in Tracker when hitting the window bounds (text widget stops
growing and starts to autoscroll) and also the Text tool in WonderBrush.
* _ScrollToOffset() is therefor no longer needed.
* The insets of the text rect are not so interesting as the original width.
In auto resizing mode, the original width is important when there is no
container view. In this setup, the text rect auto resizing is mainly needed
for auto scrolling, but it should never shrink below the original size.
* Further improved auto scrolling for right aligned and center aligned text
views, it works like R5 now. Also take the line height into account when
checking for the bounds bottom. Removed extra spacing for vertical
scrolling.

* BFS now uses the B_STAT_INTERIM_UPDATE flag for sending updates to actively

* This makes us more compatible with BeOS again; if you only asked for
B_WATCH_STAT, you will now only receive a notification if the file in
question has been closed.
* Tracker now uses B_WATCH_INTERIM_STAT to always get all updates (ie.
downloading a file will update its size and modification time in Tracker
periodically during the download).
* Wether "needsTrimming" was true or not has no influence on wether or not
the size index needs to be updated in BFS - only the actual file size is
stored there, not the on-disk size.
* Added a TODO comment in Inode::WriteAt() that it would actually need to
update the size index when changing the file size, not when the file has
been closed (but that's probably too slow).

* Placed _BTextInput_ into BPrivate namespace.
* Made _BTextInput_::AlignTextRect() smarter, it centers the line vertically,
for the case that the BTextControl has a larger label font. Improved insets
for asthetics.
* Used _BTextInput_::AlignTextRect() consistently in BTextControl, no more
custom calls to SetTextRect(). Account for minimum vertical inset of 2
pixels in GetPreferredSize().
* Consistendly select all text when gaining focus in _BTextInput_.
* Override MouseDown() in case the control did not have focus before, or else
BTextView::MouseDown() will deselct the text again and place the cursor.
(in line with BeOS behavior)
* Removed unused fBool member from _BTextInput_ and other cleanup.
BTextView:
* Reimplemented BTextView::_AutoResize() so that it works well with
BTextControl and autoscrolling when the alignment is not B_ALIGN_LEFT.
I needed two new members for this, fLeftInset and fRightInset which are
the original insets from the fTextRects. It might currently be broken
for renaming things in Tracker, I will have to check. _AutoResize() no
longer messes up the fTextRect insets.
* Fixed stray carrets sometimes being left over, mostly when auto scrolling,
but I observed them in other cases as well.
* Prevent negative scrolling offsets when autoscrolling. Fixes weird scrolling
offsets when navigating to the left.
* Reset scrolling to B_ORIGIN when SetText() is called. Fixes for example
starting to type in the middle of the control in Vision when entering new
text and autoscrolling was triggered before.

- It failed incorrectly when the target process was a process group
leader. According to the standard it shall fail when the process is
a session leader. Moving a process group leader to another process
group is fine, even if that leaves the group leaderless.
- Fixed race conditions. We need to recheck the error conditions when
we hold the team spinlock. Otherwise the situation could change
while we allocated the new process group. This was one of the
reasons for bug #1799 -- after the shell fork()'s both parent and
child invoke setpgid() for the child.
- Fixed behavior for pid == pgid. It doesn't necessarily mean that a
new group has to be created.
- Fixed update of target process group orphaned state.
- Squashed TODO: setpgid() on a child is supposed to fail after the
child has exec()ed.

This eliminates the edge case where the grow thread would not be able to create
a new area because no memory could be allocated for the allocation of the area.
As this case cannot happen anymore, it is also not possible to deadlock in
memalign. Therefore the timeout (which would only have prevented the deadlock
but wouldn't have solved the edge case anyway) has been removed too.
Add options to dump the dedicated grow heap and to only print the current heap
count to the "heap" debugger command.

but there's a special handling for 0 us relative timeouts. Syscalls
usually return B_WOULD_BLOCK instead of B_TIMED_OUT in this case, and
callers might explicitely check for it. Hence we don't convert 0 us
timeouts anymore. gdb works again.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23989 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added syscall restart support for connect(), accept(), send(), recv(),
which are implemented via ioctl()s. The actual restart support is done
in the net stack driver's ioctl() hook. Lower layers need to correctly
deal with socket timeouts, though, for which the stack module provides
support functions.
* TCPEndpoint::_WaitForEstablished() does abort now when an error
occurred earlier, so that trying to connect to an unused port fails
immediately, as it should.
* Fixed and refactored TCP connection reset handling. The new
TCPEndpoint::_HandleReset() does the job. Got rid of
TCPEndpoint::fError.
* Fixed sequence numbers for SYNC/FINI packets.
* The former two fix the problem that connections wouldn't be closed
correctly and could even be reused when trying to connect again (as
was reproducible with svnserve + svn).
* Some style cleanup in CPEndpoint.h.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23984 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Implemented automatic syscall restarts:
- A syscall can indicate that it has been interrupted and can be
restarted by setting a respective bit in thread::flags. It can
store parameters it wants to be preserved for the restart in
thread::syscall_restart::parameters. Another thread::flags bit
indicates whether it has been restarted.
- handle_signals() clears the restart flag, if the handled signal
has a handler function installed and SA_RESTART is not set. Another
thread flag (THREAD_FLAGS_DONT_RESTART_SYSCALL) can prevent syscalls
from being restarted, even if they could be (not used yet, but we
might want to use it in resume_thread(), so that we stay
behaviorally compatible with BeOS).
- The architecture specific syscall handler restarts the syscall, if
the restart flag is set. Implemented for x86 only.
- Added some support functions in the private <syscall_restart.h> to
simplify the syscall restart code in the syscalls.
- Adjusted all syscalls that can potentially be restarted accordingly.
- _user_ioctl() sets new thread flag THREAD_FLAGS_IOCTL_SYSCALL while
calling the underlying FS's/driver's hook, so that syscall restarts
can also be supported there.
* thread_at_kernel_exit() invokes handle_signals() in a loop now, as
long as the latter indicates that the thread shall be suspended, so
that after waking up signals received in the meantime will be handled
before the thread returns to userland. Adjusted handle_signals()
accordingly -- when encountering a suspending signal we don't check
for further signals.
* Fixed sigsuspend(): Suspending the thread and rescheduling doesn't
result in the correct behavior. Instead we employ a temporary
condition variable and interruptably wait on it. The POSIX test
suite test passes, now.
* Made the switch_sem[_etc]() behavior on interruption consistent.
Depending on when the signal arrived (before the call or when already
waiting) the first semaphore would or wouldn't be released. Now we
consistently release it.
* Refactored _user_{read,write}[v]() syscalls. Use a common function for
either pair. The iovec version doesn't fail anymore, if anything could
be read/written at all. It also checks whether a complete vector
could be read/written, so that we won't skip data, if the underlying
FS/driver couldn't read/write more ATM.
* Some refactoring in the x86 syscall handler: The int 99 and sysenter
handlers use a common subroutine to avoid code duplication.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23983 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Tracing of allocations, reallocations and frees
* Leak checking infrastructure to dump allocations
The leak checking code records the team and thread id when an allocation is
made as well as stores the originally requested size. It also adds the
"allocations" debugger command that can dump all current allocations (usually
a huge list) or filter by either a team or thread id. This way it's easily
possible to find leftover allocations of no more active teams/threads.
Combined with the tracing support one might be able to track down the time and
reason of an allocation and possibly find the corresponding leak if it is one.
Note that kernel heap leak checking has to be enabled manually by setting the
KERNEL_HEAP_LEAK_CHECK define to 1.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23953 a95241bf-73f2-0310-859d-f6bbb57e9c96
and pages are now kept in lists as well. This allows to return free pages once
a bin does not need them anymore. Partially filled pages are kept in a sorted
linked list so that allocation will always happen on the fullest page - this
favours having full pages and makes it more likely lightly used pages will get
completely empty so they can be returned. Generally this now goes more in the
direction of a slab allocator.
The allocation logic has been extracted, so a heap is now simply attachable to
a region of memory. This allows for multiple heaps and for dynamic growing. In
case the allocator runs out of free pages, an asynchronous growing thread is
notified to create a new area and attach a new heap to it.
By default the kernel heap is now set to 16MB and grows by 8MB each time all
heaps run full.
This should solve quite a few issues, like certain bins just claiming all pages
so that even if there is free space nothing can be allocated. Also it obviously
does aways with filling the heap page by page until it overgrows.
I think this is now a well performing and scalable allocator we can live with
for quite some time. It is well tested under emulation and real hardware and
performs as expected. If problems come up there is an extensive sanity checker
that can be enabled by PARANOID_VALIDATION that covers most aspects of the
allocator. For normal operation this is not necessary though and is therefore
disabled by default.

defined flag: NET_PROTOCOL_ATOMIC_MESSAGES.
* socket_send() now honours NET_PROTOCOL_ATOMIC_MESSAGES and returns either
EMSGSIZE if the data to be send is larger than net_socket::send::buffer_size,
or divides the data in appropriately sized chunks.
* This fixes sending >=64K over a TCP socket at once (TCP would just have
returned an error in that case).
* TCP now overrides the default send buffer size (to 32768 for now).

* Fixed libutil.h I broke yesterday: it's thought to add functions only if

* Fixed warning in realhostname.c, and pidfile.c.

When specified it desigantes that the interrupt handler should not lock the
vector with a spinlock when executing the installed interrupt handlers. This
is necessary to allow the same interrupt vector to be handled in parallel on
different CPUs. And it is required for the CPU halt to work synchronously when
there is more than one AP CPU. Though the acquire_spinlock() should cause IPIs
to be processed, only this fixed the SMP_MSG_FLAG_SYNC problem for me.
Not locking is safe as long as it is guaranteed that no interrupt handler is
registered or removed while the interrupt handler is running. We can guarantee
this for the SMP interrupt handlers we install in arch_smp_init() as they are
never uninstalled. Probably this flag should be made private though.
Restored the SMP_MSG_FLAG_SYNC when entering the kernel debugger.

missed something).
* Added sys/file.h and the flock() system call.
* common_fcntl() could forget to put back the file descriptor on some error
conditions (I guess we should introduce and use a DescriptorGetter class).
* Cleaned up fcntl.h, moved the BSD extensions S_IREAD and S_IWRITE to
sys/stat.h where they belong, and added the missing S_IEXEC to them.

we now always only use the primary ring buffer.
* Removed secondary ring buffer allocation and member fields.
* Increased size of the primary ring buffer to 65536 bytes.
* The bytes per row register is computed differently for 9xx chips.
* On G33, the overlay does not need a physical address anymore, so we
don't pass B_APERTURE_NEED_PHYSICAL to the allocation anymore for that
device.
* intel_free_memory() accidently added the aperture base to the allocation
and would therefore never free any memory.
* INTEL_RING_BUFFER_SIZE_MASK was shifted one bit to the right, didn't
cause any harm with our buffer sizes, yet, though.
* With these changes, the driver runs stable on a G33 chipset (I have not
yet tested the hardware cursor, though, it might need some work, too).
The only known issue left is that overlay flickers a bit if its buffer
is partially backed up by reserved and allocated memory.

* Removed "physical" parameter of GART's bind_aperture() - I don't think this

* The kernel now opens up to 8 debugger modules (and puts them into an array;
maybe we'll want to switch to a doubly linked list when there is the need).
* Implemented an example debugger module that prints a stack trace of the
current thread when the kernel debugger is entered (not included in the
image).

* Now uses the AGP GART module for memory management. This greatly simplifies
the memory handling, and memory is now actually allocated on demand,
instead of a fixed size (stolen memory is not freed, though).
* The Intel GART module should now also work with older chipsets.
* No longer remove the GTT size from the stolen memory; this appears to have
been a mistake in the X driver. Not sure about the BIOS popup yet.
* The AGP module (in combination with the Intel GART module) is now mandatory
to use the Intel driver.
* Removed now superfluous settings (like memory size). Only enabling/disabling
the hardware cursor is still supported.

as custom modules of graphics drivers if they want to (could be used for the
Radeon PCI GART stuff, for example).

Intel chips will come later).
* Renamed agp bus manager to agp_gart to reflect its new functionality (even

For commands with this flag set, the parser won't parse the
arguments provided (it will only check for matching parentheses and

write code aligned to what one has written in the comment (or the
other way around).
* Made trace_entry structure doubly linked, by introducing a
previous_size member. By using bit fields, shrinking the flags field
to 4 bits, and not saving the lower two bits of size and previous_size
(which are always 0 due to alignment), the structure remains 4 byte
sized and can still address the same entry size.

* "traced" command:
- Use static variable for the iteration state rather then cluttering
the temporary debug variable name space.
- The <count> parameter can now be negative, in which case the entries
before (and including) <start> are printed.
- Added a new optional parameter, specifying the maximal number of
entries to be filtered. Filtered iteration is beautifully

num_blocks/sub_num_blocks fields of the old transaction. Even worse, it did

* get_writable_cached_block() did not correctly maintain the number of blocks

* write_cached_block() did not free the original_data of a block when it wrote
it back as part of a previous transaction.
* Changed "cookie" for cache_next_block_in_transaction() to "long", so it will
be 64 bits when needed.
* Improved the API for detaching sub transactions: you can now get the blocks

cache_block_in_main_transaction() function.
* BFS now flushes the log when there is no space left for the current
transaction.
* _WriteTransactionToLog() allocated a "vecs" array, but never freed it.
* _WriteTransactionToLog() now also supports detaching the current sub
transaction if the whole thing is getting too large (it will now also panic
if that doesn't work out).
* Removed a useless optimization: making the blocks available in the cache
isn't really needed, as all blocks in a transaction are locked into the
cache, anyway.
* Implemented Transaction::WriteBlocks().
* Minor cleanup, removed some dead code, fixed warnings in the fs_shell's
block_cache when compiled with debug output on.

- Persistent and temporary uint64 variables. The former kind is set
only by the user. The latter (those prefixed "_") can be set
automatically by commands, thus e.g. making it easier to access
members of a dumped structure. They are unset when the next command
is invoked. The special temporary variable "_" is defined as a
command's return value.
- Expressions can contain nested command invocations using brackets
("[ ... ]").
- Command lines are parsed by the expression parser, too. They can
contain command invocations (in brackets) and expressions (in
parentheses).
* Added debugger commands:
- expr: Evaluates the given expression and prints the result.
- unset: Undefines a variable.
- vars: Prints the values of all defined variables.
* Moved debugger command code into its own source file.

transaction ends or has been aborted.
* BFS now listens for transactions when it created an inode to see if
the transaction will be aborted without freeing the inode (in which
case it will panic for now).
* Started implementing tracing support, but it's not working yet.
* Minor cleanup.

As (our) gcc unfortunately uses atexit() to clean up lazily initialized static
variables inside functions we have to ensure that we do the right thing with
unloadable shared objects. In case a shared object was unloaded that installed
an atexit() hook the application would crash on exit. We now implement a
callback into libroot that is used to call all the atexit() hooks of a
component that is to be unloaded. Most prominently this fixes the media_server
crash at shutdown.

* Added function to allocate space in the buffer.
* Dump() now fills a buffer instead of printing its data directly.
* This allows the new "#pattern" argument of the "traced" command to
work. When you're using that, the index of the trace entry is printed
out, too, so that you can then get a full dump around the hits.
* Added an AddDump() method to the AbstractTraceEntry class so that
there is no need to call the inherited function anymore.
* Minor cleanup.

(ie. not compiling in tracing would have crashed if some module tried
to use it).
* Added total entries count to the KDL command output.
* Fixed computing the start index of the KDL command.

23139 into trunk, with roughly the following changes (for details svn
log the branch):
* The int 99 syscall handler is now fully in assembly.
* Added a sysenter/sysexit handler and use it on Pentiums that support
it (via commpage).
* Got rid of i386_handle_trap(). A bit of functionality was moved into
the assembly handler which now uses a jump table to call C functions
handling the respective interrupt.
* Some optimizations to get user debugger support code out of the
interrupt handling path.
* Introduced a thread::flags fields which allows to skip handling of
rare events (signals, user debug enabling/disabling) on the
common interrupt handling path.
* Got rid of the explicit iframe stack. The iframes can still be
retrieved by iterating through the stack frames.
* Made the commpage an architecture independent feature. It's used for
the real time data stuff (instead of creating a separate area).
* The x86 CPU modules can now provide processor optimized versions for
common functions (currently memcpy() only). They are used in the
kernel and are provided to the userland via commpage entries.
* Introduced build system feature allowing easy use of C structure
member offsets in assembly code.
Changes after merging:
* Fixed merge conflict in src/system/kernel/arch/x86/arch_debug.cpp
(caused by refactoring and introduction of "call" debugger command).

resized but still had dirty pages to be written back,
vm_cache_resize() (which is called with the inode lock being held)
deadlocked with the page writer.
* Now, I reintroduced busy_writing: it'll be set by everything that
writes back pages (vm_page_write_modified(), and the page writer),
and will be checked for in vm_cache_resize() - other functions are not
affected for now, AFAICT.
* vm_cache_resize() will clear that flag, and the writer will check it
again after it wrote back the page (which will fail when it's outside
the file bounds), and if it's cleared, it will get rid of the page
(if the file has been resized again in the mean time, writing it will
succeed then, and we'll keep the page around).

appear: when freeing a modified page, it wouldn't have a cache
anymore, but set_page_state_nolock() depended on it.
* To work around this, I added a vm_page_free() function, which the
caches that free modified pages have to call (but others may, too).
It will correctly maintain the sModifiedTemporaryPages counter in case
the cache has already been removed.

* Implemented mapping the GTT area for i9xx chips other than the i965. This should also fix the
driver working with these chips at all.
* The memory used by the driver now take the GTT area into account - before the GTT could be
overwritten theoretically...
* Added fix for some i965 quirks from the X driver.
* Added some overlay definitions for the i965.
* Started support for G33 overlay (not complete yet).

Replaced IDE_ADAPTER_IS_PRIMARY by IDE_ADAPTER_CHANNEL_INDEX to support more than 2 bus master channels,
and made ide_adapter aware of 3rd and 4th channel when calculating bus master dma address.
Fixed bus master DMA support in legacy_sata driver for tertiary and quaternary channel, channel 3 and 4
were using the DMA engine of primary and secondary channels (that might have destroyed your data).
Use PCI_address_io_mask instead of ~PCI_address_space (no functional change).

- do not use alpha cursor because it does not support inverting of source pixels.
- Fixed wrong usage of if-statement inside switch-statement
- Sync at end of SCREEN_TO_SCREEN_BLIT so that app_server does not write to frame buffer while accelerated operation is still running.

* improved naming of some private BView functions and used our underscore
prefix
* added a _DrawAfterChildren method to BView which does the necessary setup
and calls the DrawAfterChildren hook
* call the new _DrawAfterChildren method in the BWindow implementation, this
was easy since the view tokens are already hierachically sorted
* implement support for B_DRAW_ON_CHILDREN in the app_server's ViewLayer, it
simply means that children are ignored for the views clipping region, any
drawing methods will paint over children (therefor the B_DRAW_ON_CHILDREN
flag is even properly named)
With these changes, support for B_DRAW_ON_CHILDREN and the DrawAfterChildren()
hook are implemented and behave exactly as on R5 as far as I can tell, also
for the view background painting.

* Removed other (disabled) hyper threading code per the notes in the corresponding ToDo
* Limit the detected CPU count to 2 for now as I wasn't able to get it working in either emulation nor real hardware with more than 2 CPUs
* Added a reserved byte to the mp_config_table struct, it worked only by luck as the compiler did padding there to get to the same size

* Therefore, I've added an I/O control that let's it update the boot block
part of this block, so that makebootable can use it on a mounted volume

* Minor cleanup.

passes that information on to the kernel. This should fix wrong bytes per row with
certain resolutions and graphics cards.
* The boot loader now recognizes 15 bit modes that are advertised as 16 bit modes.
This should fix wrong colors in 16 bit modes on some cards.

device geometry.
* If SetTo() reports no media, and GetGeometry() fails, the device geometry
is now reset as well.
* KDiskDeviceManager::_ScanPartition() no longer unmarks the partition busy;
this is now done by the caller, and done independently from the outcome of
_ScanPartition(). This also fixes the problem that devices with no media
were never marked unbusy (and thus were ignored subsequently).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22912 a95241bf-73f2-0310-859d-f6bbb57e9c96

that can be used by file systems.
* Changed the way the file cache works: instead of reading/writing to the
underlying device directly, it can now be used for any data source, ie.
also network file systems.
* As a result, the former pages_io() moved to the VFS layer, and can now be
called by a file system via {read|write}_file_io_vec_pages() (naming
suggestions are always welcomed :-)). It now gets an FD, and uses that to
communicate with the device (via its fs_{read|write}_pages() hooks).
* The file_cache_{read|write}() functions must now be called without holding
an I/O relevant file system lock. That allows the file cache to prepare the
pages without colliding with the page writer, IOW the "mayBlock" flag can
go into the attic again (yay!).
* This also results in a much better performance when the system does I/O and
is low on memory, as the page writer can now finally write back some pages,
and that even without maxing out the CPU :)
* The API changes put slightly more burden on the fs_{read|write}_pages()
hooks, but in combination with the file_map it's still pretty straight
forward. It just will have to dispatch the call to the underlying device
directly, usually it will just call its fs_{read|write}_pages() hooks
via the above mentioned calls.
* Ported BFS and FAT to the new API, the latter has not been tested, though.
* Also ported the API changes to the fs_shell. I also completely removed its
file cache level page handling - the downside is that device access is no
longer cached (ie. depends on the host OS now), the upside is that the code
is greatly simplified.

K{Disk,File,Partitioning}System writing methods. It is now required
that the caller has marked the concerned partitions busy, hence we can
(read-)access them without needing a lock. The module interfaces will
will be changed to take advantage of the fact as well. The methods take a
disk_job_id instead of a KDiskDeviceJob* now, though I haven't quite
decided, whether we need it at all or just want to add a special
handling in the cases where notifications during the operation make
sense.
* Reimplemented the disk device write support syscalls (save
_user_move_partition() for which other module hooks are needed). They
call the KDiskSystem methods, now.

app server as well (ie. AS_GET_MONITOR_INFO).

* Fixed build under BeOS.

collection of no-op methods, which could as well be implemented in
BPartition itself. This makes the Delegate hierarchy unnecessary:
MutableDelegate becomes Delegate, and we save a few casts as a side
effect.

builds the object hierarchy, the second will (in case of MutableDelegate)
let the disk systems do their initialization. This way the disk systems
already find a fully functional object hierarchy they can work with.
* Child creation also takes a partition name as a parameter, now.
* Implemented BMutablePartition child creation/deletion.
* The BDiskSystemAddOn/BPartitionHandle::Validate*() methods return a
status_t instead of a bool, now.

the accelerant, as well as its EDID info. B_GET_PREFERRED_DISPLAY_MODE and
B_GET_EDID_INFO are both optional. The preferred mode will be taken from the
EDID info if only the latter hook is implemented, or the former returned an
error.
* Currently, the app_server should correctly set the preferred mode on start,
but no accelerant supports that yet, so it's not really tested.

to create their mode list. Once it's done, it should cover all possible cases,
and allow the base mode list to reside in the app_server (under Haiku, at least),
so that all drivers will benefit from an updated list.
Right now, it might already work to a degree, but it's not yet tested.

vm_page_reserve_pages() and vm_page_allocate_page() will now steal pages from
the inactive queue as needed.
* We currently never steal active pages anymore, but this might need to be
revised later (therefore, the page scanner never waits anymore, but uses
mutex_trylock() to lock a cache).
* The page scanner and writer now both run at normal priority - let's see how
that will work out.
* Introduced an inactive queue.
* Instead of shuffling pages around in the queue (and therefore destroying LRU)
the page stealing mechanism now uses a marker page to be able to release the
page lock without losing its position in the queue.
* The page writer now always grabs the whole release count of the semaphore, so
that there won't be a huge backlog to catch up with.
* vm_page_num_free_pages() now also includes the inactive queue as well as the
reserved pages (they are no longer regarded as free pages).
* Added a insert_page_after() function that inserts a page after another one,
needed by the marker code.
* clear_page() now gets a vm_page instead of a physical address which simplified
some code.
* Removed superfluous initialization of the queues (if those aren't zeroed on
start, we would have serious problems, anyway).
* Removed old and unimplemented dump_free_page_table() ("free_pages") KDL
command.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22506 a95241bf-73f2-0310-859d-f6bbb57e9c96
it intended to. That resulted in more writable pages where you wouldn't want
them (ie. allowing the area to change pages in lower caches).
* We were losing modified pages: vm_unmap_pages() sometimes has to preserve
the modified flag (eg. when called from page fault).
* Both of these were responsible that stealing active pages would crash
applications - even if less likely, this could also have happened when
stealing inactive pages. Therefore, I've activated stealing active pages
again.
* The page writer now pushes the pages of busy vnodes to the end of the queue,
so that it won't pick them up again too soon (the vnode destruction would
be in the process of writing those pages back, anyway).
* The page thief now triggers the page writer to run once it has to steal
active pages. This might be a bit too aggressive, though.

hence CancelInputMethod()), but it implements part of it. To avoid code
duplication, I added a private _SetRunArray() call, which does most of
the work, except cancelling the input method, and calling Refresh().
Removed some unneeded code from CancelInputMethod(), some small changes
in HandleInputMethodChanged.

busy vnodes.
* dir_create_entry_ref() used get_vnode() incorrectly (and could therefore
potentially prevent a file system from doing proper locking when called
from the kernel).
* The vnode_store now uses this for its acquire_unreferenced_ref()
implementation (and therefore for the page writer).
* read_into_cache() and write_to_cache() were still marked inline.
* The system will now wait 10 secs for a busy vnode before returning an error.
* It will also no longer panic in that case.

additional partition_data* child parameter now.
* _user_get_partitionable_spaces() doesn't need to copy the buffer into
the kernel, since it is no input parameter. It also copies back the
actual partitionable spaces count on error, now -- B_BUFFER_OVERFLOW
is returned when the buffer was too small, but then the count must be
returned too.
* Fixed several instances of syscall implementations that unloaded a disk
system, although they didn't load it in the first place. This screwed
up the load count with undesirable consequences.
* _user_create_child_partition() would set the size to the supplied
offset.
* Fixed broken loop in KPhysicalPartition::CreateShadowPartition().
* KPartition::RemoveChild() notified the listeners about the wrong
event.
* Intel partitioning module:
- The *_get_partitionable_spaces() correctly return B_BUFFER_OVERFLOW
now, if the supplied buffer is too small.
- Implemented a part of pm_shadow_changed(), which creates and updates
the PartitionMap, so that the validate_*() hooks have a chance to
work at all.

partition, if it exists.
* Added B_PARTITION_SHADOW[_CHILD] partition pseudo operation values for
the shadow_changed() hook, notifying a disk system, that a shadow
partition has been created.

interfere with the page thief, we always need to have reserved a page for
this upfront. I introduced a function to the vm_translation_map layer that
estimates how much pages a mapping might need at maximum. All functions that
map a page now call this and reserve the needed pages upfront.
It might not be a nice solution, but it works.
* The page thief could run into a panic when trying to call vm_cache_release_ref()
on a non-existing (NULL) cache.
* Also, it will now ignore wired active pages.
* There is still a race condition between the page writer and the vnode
destruction - writing a page back needs a valid vnode, but that might just
have been deleted.

system initialize() hooks. It's often the only info about the
partition one needs and thus locking the partition just to get it is
no longer necessary.
* intel partitioning system:
- Removed passing around block sizes. We require 512 byte sectors
anyway. In fact using the parent partition's block size was even
wrong.
- Simplified writing the partition map sector.
- Simplified and corrected the partition map initialization.
- We don't fail identifying a partition anymore, if the partition map
contains no partitions. We would never identify a freshly
initialized partition map before.
- Made pm_identify() more intelligent: It determines the priority to
return depending on whether the partition is the device itself and
whether we have recognized child partitions.

does no longer give partitioning systems precedence over file systems.
The one with the greater identification priority wins. ATM, if a file
system wins, we still mount the first file system that recognized the
partition at all, though.

the unmapped page.
* This is needed by everyone who calls this to make sure modifications to a
page aren't ignored. Namely, the page scanner and the page thief were
affected.
* Cleaned up locking the page's cache a bit in page_thief(); there is now
a helper class that takes care of everything.

* the page writer don't allow to block, while all other writers do. This fixes
bug #1509. The reason the page writer needs this is because it marks several
pages from different caches as busy.
* Fixed a warning about ASSERT being defined already in BFS, since
util/DoublyLinkedList.h now includes debug.h.

dprintf() with the exception that it doesn't write anything to the

vfs_select.h, respectively moved most of it into the new kernel
private header wait_for_objects.h.
* Added new experimental API functions wait_for_objects[_etc](). They
work pretty much like poll(), but also for semaphores, ports, and
threads.
* Removed the "ref" parameter from notify_select_events() and the
select_sync_pool functions as well as from fd_ops::fd_[de]select(). It
is no longer needed. The FS interface select() hook still has it,
though -- the VFS will always pass 0.
* de]select_fd() take a select_info* instead of a select_sync* + ref
pair, now. Added respective functions for semaphores, ports, and
threads.

and thread spinlock was reverse in Wait() and Notify(). The thread lock
is now the outer lock -- this way it is still possible to call Notify()
with the thread lock being held.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22401 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Reworked the select support:
- The io_context additionally stores a table of lists of select_infos,
which enables it to deselect events of a pending select() when
closing a FD. This prevents a race condition potentially causing a
write to stale memory.
- The opaque selectsync* passed to FSs is now actually a select_info*.
This was necessary, since the FDs deselect() hook (unlike the
select() hook) doesn't take a "ref" argument and deselecting a
single info (e.g. caused by a premature close()) was not possible.
The select() hook's "ref" argument has become superfluous.
- It should now be relatively easy to implement a poll_on_steroids()
that can also wait for objects other than FDs (e.g. semaphores,
ports, threads etc.).
* Set/reset the signal mask in common_select(). This makes pselect()
work as required.
* Reorganized vfs_resize_fd_table().

characters first, and then falls back to take everything. fTrigger is now
uint32 and works with all unicode characters; unlike in BeOS, the
MenuTriggerTest application now works correctly in Haiku.
* fTriggerIndex is now a character position, not a byte position of the label;
this allows BMenuItem::DrawContent() to draw the trigger at the correct
position, even if there are multi-byte UTF-8 characters.
* The above fixed bug #1506; triggers are still not working, though.
* Rewrote Menu.h header.
* Renamed all private methods (that are not called by BWindow) to have the
underscore prefix.
* Removed unused methods.
* Some minor cleanup.

components - now, we divide the initialization of that service into two parts
which allows this (before, most handlers were gone after boot).
* Added debugger command that dumps the low memory handlers.
* The slab allocator now registers its low memory handler with a higher
priority, so that it'll run before the potentially heavier ones.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22374 a95241bf-73f2-0310-859d-f6bbb57e9c96
* We now have a page writer that takes some pages from the modified queue
and writes it back every few seconds. It can be triggered by the page
scanner to do that more often, though. That mechanism can be greatly
improved once we have our I/O scheduler working.
* Removed vm_page_write_modified_page() again - it was all "eaten up" by
the page writer.
* Reworked vm_page_write_modified_pages() a bit: it now uses
vm_test_map_modification() and vm_clear_map_flags() instead of the
iterating over all areas which wouldn't even work correctly.
The code is much simpler now, too.
* You usually put something to the tail of a queue, and remove the contents
from the head, not vice versa - changed queue implementation to reflect this.
* Additionally, there is now a enqueue_page_to_head() if you actually want the
opposite.
* vm_page_requeue() allows you to move a page in a queue to the head or tail.
* Replaced vm_clear_map_activation() with vm_clear_map_flags() which allows
you to clear other flags than PAGE_ACCESSED.
* The page scanner dumps now some arguments with each run.
* Removed the old disabled pageout_daemon() from NewOS.
