waiting for a heap grow.
* Use that nogrow version in the VM code to avoid a deadlock with the address
space lock when a grow operation would try to create an area while a malloc
happened from such a function in the VM.
* When waiting for a grow to happen, notify the waiting thread from the grower
also if it failed to allocate a new heap. Otherwise a thread would just sit
there and wait until another thread requested growing too and that one
succeeded (or just forever in the worst case).
* Make the dedicated grow heap growable too. If the current grow heaps run low
on memory it will instruct the grower to allocate a new grow heap. This
reduces the likelyhood of running out of memory with no way to grow to a
minimum. As the growing is done asynchronously it is still possible to
happen, but it is highly unlikely as the grow heap is solely used to
allocate memory in the process of creating new heap areas and it will even
try using normal public memory if the dedicated memory has run out.
* Reduced the dedicated grow heap from 2 to 1MB. As it can now grow itself, it
doesn't need to last so long.
* Extract heap creation into it's own function that does area creation and heap
attach and use this function for growing normal and grow heaps.

and remove the then unneeded mutex_init() for them.
* Remove the workaround for allowing uninitialized mutexes on kernel startup.
As they are all initialized statically through the MUTEX_INITIALIZER() now
this is not needed anymore.
* An uninitialized mutex will now cause a panic when used to find possibly
remaining cases.
* Remove now unnecessary driver_settings_init_post_sem() function.

* Sort the available keymaps list in the config file and add 'dv'

keymap there too.
* Add a config header where one can select what KDL keymap should be used
(currently only 'us' and 'sg' are available though).
* Provide a third keymap that is used when the alt modifier is used (the swiss
german keymap is pretty useless without alt as all the useful keys like
backslash and curly braces use alt).
Our KDL is so powerful and nice to use, the only thing that bothered me was
that I always had to think about where some of the special keys are located in
the US keymap. So this simple compile-time keymap switching provided to be
helpful for me and might be for others too. Keymaps for other layouts obviously
have to be written before this becomes really useful.

* The VESA driver now supports gettings the EDID information as well; this
is necessary now, since the app_server no longer takes over the mode the
boot loader had chosen.

the kernel part again.

B_DEBUG_SPINLOCK_CONTENTION is defined to 1. It typedefs spinlock to a
structure (thus breaking BeOS binary compatibility), containing a
counter which is incremented whenever a thread has to wait for the
spinlock.
* Added macros for spinlock initialization and access and changed
code using spinlocks accordingly. This breaks compilation for BeOS --
the macros should be defined in the respective compatibility wrappers.
* Added generic syscall to get the spinlock counters for the thread and
the team spinlocks.

pipes in the shell, though the semantics is a little different: The
second command is invoked whenever the first command has written a
complete line. The line is passed as last argument to the second
command. The new command flag B_KDEBUG_PIPE_FINAL_RERUN causes the
second command to be invoked again (with NULL argument) after the
first command is done.
* Added kprintf_unfiltered() and kputs_unfiltered() which bypass the
pipe mechanism and directly print to the bluescreen/serial output.
* Moved most commands from debug.cpp to the new
debug_builtin_commands.cpp.
* B_KDEBUG_DONT_PARSE_ARGUMENTS commands don't get an argument anymore,
if it would consist of white space only.
* Added new debugger command return value B_KDEBUG_ERROR, which
indicates that executing the command failed. This return code will
abort a complete pipe.
* Since debugger commands can nest (i.e. one command can invoke another
one) the setjmp()/longjmp() mechanism to restore the stack after a
page fault in a command needs more than one jump buffer.
* Added abort_debugger_command(), which longjmp()s out of the currently
executed command. This will also abort the current pipe.
* When pagination is enabled pressing "a" will abort the running command
(as opposed to "q" which only disables the blue screen output, but
lets the command continue).
* Added debugger commands:
- "grep" which can be used to filter output by pattern. Removed the
"filter" command and the underlying mechanism that did that before.
- "head" which prints only the first lines of output of another
command.
- "wc" counts lines, words, and characters of another command's
output.

things a little.

* Moved devfs from fs/ to device_manager/, and separated the legacy driver
support from it.
* Removed fast_log module.
* There are a couple of (temporary) regressions, though:
- legacy SATA and ISA IDE support is disabled, the drivers haven't been
ported yet.
- The not yet used ATA bus manager hasn't been ported yet, either.
- AHCI changes have not been tested.
- the listdev command has been removed from the build (as it currently
doesn't work anymore).
- device manager generated IDs currently are not freed anymore when a device
node is removed.
- generic drivers can't yet use the new driver architecture.
- simple busses that do not support device types won't work yet.
- legacy driver publishing/unpublishing (ie. what USB needs) has not been
tested, and may be broken.

vm_page_write_modified_pages(), save that it only writes pages in the

facility to call BIOS interupt handlers. The function must only be called from
a user thread context because the lower 1MB of the address space is used.

Changed condition variables so that it is allowed to block (e.g. lock
mutexes etc.) between Add() and Wait(). This fixes#2059, since the
block writer used them this way and could thusly fail to wait for a
condition variable, causing a temporary stack object to be used past its
lifetime.

to contain headers shared by kernel and userland (mainly libroot).
* Moved quite a few private kernel headers to the new location. Split
several kernel headers into a shared part and one that is still kernel
private. Adjusted all affected Jamfiles and source in the standard x86
build accordingly. The build for other architectures and for test code
may be broken.
* Quite a bit of userland code still includes private kernel headers.
Mostly those are <util/*> headers. The ones that aren't strictly
kernel-only should be moved to some other place (maybe
headers/private/shared/util).

address space that is fully locked and marked B_KERNEL_AREA. It can
thus be accessed by the kernel without additional checks.
* For each userland thread we do create a user_thread structure in that
area. The structure is accessible from userland via TLS, using the
private get_user_thread() function.
* Introduced private userland functions [un]defer_signals(). They can be
used to cheaply disable/re-enable signal delivery. They use the
user_thread::defer_signals/pending_signals fields which are
checked/updated by the kernel.

by short/pretty/module name - since they should all be unique, I put them
in a single namespace, please complain if you don't like that :-)

new user thread.

* Changed the semantics of unnamed semaphores. Before parent and child
of a fork() would always share an earlier created semaphore. Now we do
that only, if the "shared" parameter of sem_init() was true. That's
still not quite the behavior Linux and Solaris have, but should be
perfectly fine with how reasonable code would use the API.
* There's a global table for shared unnamed semaphores now. ATM a
semaphore is leaked when no one explicitly destroys it (just as with
named sems).
* Enforce per-team and global semaphore number limits.

- Implemented BMediaFile::Copyright, which just calls Copyright() of the extractor. So this is just a simple pass through.
- Style cleanup (mostly whitespaces)
Problem is that our readers currently return the copyright of the source code, not the copyright of the MediaFile itself, like the BeBook documents. Thus, we might need to change all readers to return appropiate data or behave differently for Haiku readers.

* Trivial adjustments of code using mutexes. Mostly removing the
mutex_init() return value check.
* Added mutex_lock_threads_locked(), which is called with the threads
spinlock being held. The spinlock is released while waiting, of
course. This function is useful in cases where the existence of the
mutex object is ensured by holding the threads spinlock.
* Changed the two instances in the VFS code where an IO context of
another team needs to be locked to use mutex_lock_threads_locked().
Before it required a semaphore-based mutex implementation.

* Added cutex_init_etc() which has an additional "flags" parameter.
The only specifyable flag is CUTEX_FLAG_CLONE_NAME, which causes the
function to strdup() the given name and free() its copy in
cutex_destroy().
* cutex_destroy() does now unblock waiting threads.

name, couldn't resist :-P). It's semantically equivalent to a mutex,
but doesn't need a semaphore (it uses thread blocking and a simple
queue instead). Initialization can't fail. In fact it is ready to use
without initialization when living in the bss segment, also in the
early boot process. It's as fast as a benaphore in cases of low lock
contention, and faster otherwise. Only disadvantage is the higher
immediate memory footprint of 16 bytes.
* Changed how the "thread" and "threads" debugger commands list the
objects they are waiting for. Cutexes are also included.

* Made the pointers const.
* Changed how the ARP module maintains its arp_entry::request_buffer: it
now uses the atomic_pointer*() functions to make sure there is no race
condition, and it's deleted only once.
* Getting an ARP entry would return uninitialized data, if the entry hadn't
been resolved yet.

* Added "mode" parameter to set_paranoia_check(), which specifies
whether the check is supposed to already exist/not exist yet. This
allows for, as it turns out, very useful additional tests. Added
{ADD,UPDATE}_PARANOIA_CHECK macros that imply the used "mode"
parameter.
* PARANOIA_SLOT_COUNT was accidentally redefined in the source file.
* Fixed remove_paranoia_check(). It didn't remove anything.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25207 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added capture_tracing_stack_trace() which allocates space in the
tracing buffer and captures the stack trace according to the given
parameters.
* Added TraceOutput::PrintStackTrace() to print a stack trace thus
created.
* Added TraceEntry::DumpStackTrace() callback which is supposed to print
a stack trace for the entry, if it can do that.
* Added "--stacktrace" switch to the "traced" command, which causes the
stack traces for all entries that have one to be printed as well.

* Publish /dev/ptmx. Opening it will open a fresh pty master. In
principle /dev/pt/ is obsolete now, but I guess we keep it around for
compatibility with BeOS. Though there shouldn't be many applications
opening a pty, that we might be interested in...
* New ioctls B_IOCTL_GET_TTY_INDEX (returns the tty index) and
B_IOCTL_GRANT_TTY (grants tty slave access rights).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25133 a95241bf-73f2-0310-859d-f6bbb57e9c96

Init() on those, and add entries directly with the
ConditionVariable::Add() method.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25110 a95241bf-73f2-0310-859d-f6bbb57e9c96

that strings can be passed without casting. Passing a string could
maybe be made a convention for THREAD_BLOCK_TYPE_OTHER.

thread_block(), thread_unblock(),...) that allow a thread to wait for
something without needing a semaphore or condition variable. It can
simply block and another thread can unblock it. Supports timeouts and
interrupting. Both semaphores and condition variables use this
common mechanism, now.
* Semaphores:
- Some simplifications due to the thread blocking mechanism.
- Changed locking order to sem -> thread. It was the other way around
before and when introducing the wait_for_objects() support I had
also introduced a situation where the locking was reverse, which
could potentially cause a dead lock on SMP systems.
- Instead of queueing thread structures, a semaphore queues
queued_thread entries now, which are created on the stack. The
thread::sem structure could thus be removed.
- Added sem_entry::net_count, which is sem_entry::count plus the
acquisition count of all waiting threads. This number is needed in
remove_thread_from_sem() and instead of computing it there we
maintain it.
- Fixed remove_thread_from_sem(). It would not unblock threads, if
the sem count was <= 0.
- Made sem::last_acquirer unconditional. It is actually needed for
sem_info::latest_holder. Fixed fill_sem_info() accordingly.
- Added some optional tracing output, though only via ktrace_printf().
* Condition variables:
- Could be simplified significantly through the use of the thread
blocking mechanism. Removed a good deal of unnecessary code.
- Moved the ConditionVariableEntry "flags" parameter from Wait() to
Add(), and adjusted all places where condition variables are used
accordingly.
* snooze() uses thread_block_with_timeout() instead of a semaphore.
* Simplified thread interrupting in the signal and user debugger code.
Instead of separate functions for threads waiting on a semaphore or
condititon variable, we only have a single thread_interrupt(), now.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25099 a95241bf-73f2-0310-859d-f6bbb57e9c96
- If the hook of the timer we're cancelling is currently being
executed, we do now wait till it is finished. This is how the BeBook
specifies the function to behave.
- Periodic timers would not be cancelled, if their hook was being
invoked at the same time, since they weren't in the queue during
that time.
- Since we know the CPU on which the timer is scheduled (timer::cpu),
we don't have to look through any other CPU queue to find it.
- Fixed the return value. It should report whether the timer had
already fired, and was not always doing that.
* Added private add_timer() flag B_TIMER_ACQUIRE_THREAD_LOCK. It causes
the thread spinlock to be acquired before the event hook is called.
cancel_timer() doesn't wait for timers with the flag set. Instead we
check in the timer interrupt function after acquiring the thread
spinlock whether the timer was cancelled in the meantime. Calling
cancel_timer() with the thread spinlock being held does thus avoid any
race conditions and won't deadlock, if the event hook needs to acquire
the thread spinlock, too. This feature proves handy for some kernel
internal needs.
* The scheduler uses a B_TIMER_ACQUIRE_THREAD_LOCK timer now and
cancel_timer() instead of the no longer needed
_local_timer_cancel_event().

ones) for wait_for_child(), which is notified when any job control

* Only kept the userland_ipc.h header for now, to remember us about the
former userland server driver (that I also removed - it can always be
resurrected from SVN if needed).

* 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.

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.

- 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()
constants.
* 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.
* Moved non-shared vesa driver data into its own file vesa_private.h.

- 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.
* MediaNodes having such a ControlPanel are rarely used as parameterwebs should provide you everything. But for instance the vst MediaAddOn uses it and some others do as well.

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().

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 the feature of an animated boot screen (icons lighting up at
different boot stages).
* Added first version of new boot splash images, generated by the new
hsbg tool. (Also finally contains the "new" Haiku logo.)
changes by myself:
* Added Artur to the contributors list in About System.
* Fixed some left overs in the patch, kept tracing turned off.
TODO:
* Remove the need for hard coding the icon positions. (Maybe generate
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.

fork(), load_image(), and exec().
* Implemented the get[e]{u,g}id(), set[[r]e]{u,g}id() family for real.
* getgroups() also calls the kernel now, but only returns the effective
group ID. Supplementary groups support is still missing.

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.

of the resolved ToDo, but could probably be made more efficient. Instead of
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.

* Use the common 0xfffd character as a substitute for invalid characters
* 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

* driver_entry::api_version now stores the actual version instead of a
pointer to it.
* Renamed node_path_entry to path_entry and reused it for driver
reloading: handle_driver_events() will now also check for drivers to
add in the sDriversToAdd list.
* 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
it removable since we never get/put the node. We now do, and so the
node is actually removed as intended.
* Added "devfs_driver" KDL command.
* Minor cleanup.

workspaces view can now be any view in the hierarchy.
* Added private view flag kWorkspacesViewFlag that identifies such a
view - note though, that you must not remove a view before closing or
hiding its window for now (and that you still need to set the
kWorkspacesWindowFlag, too).
* Fixed Workspaces check for valid screen coordinates; after a crash, it
managed to open its window offscreen for me.
* Added a ViewLayer method FindView() that finds a view with the
specified flags set.

* Added team::flags. Currently only used for setting a flag when a team
has exec()ed.
* Some improvements of _user_setpgid():
- 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.

* 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).

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).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23794 a95241bf-73f2-0310-859d-f6bbb57e9c96
* 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.

* It now also serves as a generic GART manager and accepts bus modules as well
as custom modules of graphics drivers if they want to (could be used for the
Radeon PCI GART stuff, for example).
* Implemented GART support module for Intel i965 and G33 chipsets (the other
Intel chips will come later).
* Renamed agp bus manager to agp_gart to reflect its new functionality (even
though the AGP functionality is already outdated (due to PCIe), the GART
stuff remains current).
* Adapted existing users of the AGP bus manager to the API changes.
* Not very well tested yet...

For commands with this flag set, the parser won't parse the
arguments provided (it will only check for matching parentheses and
brackets), but will pass the unparsed argument list string to the

* Set the new flag for the "expr" command, so one doesn't have to quote
the expression to evaluate anymore (or put it in parentheses).
* Fixed tokenizing of quoted and unquoted strings in expression mode.

* Removed the public hash_grow() function again (at least for now, it's only
private).
* Removed the newSize argument from hash_grow(); it will compute the new size
automatically.
* The block cache is now using hash_insert_grow() instead of hash_insert()
which should make hash lookups much faster with some 10 thousand blocks,
also increased the initial table size from 32 to 1024...

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.
* kBufferSize is no longer one less than it could be.
* "traced" command:
- Use static variable for the iteration state rather then cluttering
