Switch to a 64-bit time_t everywhere except 32-bit x86.

Thus, BeOS compatibility is preserved (and there is no risk of
breaking GCC5<->GCC2 interoperation on hybrid builds.)

This commit only makes the actual change, the build fixes are
in the next commit.


# 6f7fc220 07-Mar-2016 Axel Dörfler <axeld@pinc-software.de>

NodeMonitor: Added B_WATCH_CHILDREN flag.

* Added a directory argument for notify_{stat/attribute}_changed().
* This allows to watch only a directory, and get the notifications for
all of its files, not just add/remove entry notifications.


# efb0a3a8 17-Aug-2015 Michael Lotz <mmlr@mlotz.ch>

EntryCache: Add entry_cache_add_missing() for negative caching.

It provides a way for filesystems to cache a lookup failure and
therefore prevents repeated lookups of missing entries. This is a
common scenario for example in command lookup and compiling, where
each directory in PATH or each include directory is searched for the
given entry.


# 98731302 14-Jan-2015 PulkoMandy <pulkomandy@pulkomandy.tk>

fssh_api_wrapper: fix build on non-Haiku.

* I'm not sure why strings.h needs to be included before <new>, but it
wouldn't work otherwise.


# 50d274f7 25-Oct-2014 Axel Dörfler <axeld@pinc-software.de>

fs_shell: Added missing new permission check function.

* Fixes the build.


# dec78bb2 20-Jun-2014 Ingo Weinhold <ingo_weinhold@gmx.de>

Add new error codes B_PARTIAL_{READ,WRITE}


# 29a84508 04-Aug-2013 Axel Dörfler <axeld@pinc-software.de>

Added B_TRIM_DEVICE ioctl.


# 077c84eb 05-Nov-2013 Pawel Dziepak <pdziepak@quarnos.org>

kernel: atomic_*() functions rework

* No need for the atomically changed variables to be declared as
volatile.
* Drop support for atomically getting and setting unaligned data.
* Introduce atomic_get_and_set[64]() which works the same as
atomic_set[64]() used to. atomic_set[64]() does not return the
previous value anymore.


# 1674a53a 30-Mar-2012 Axel Dörfler <axeld@pinc-software.de>

Added recursive_lock_transfer_lock() to the fs_shell.


# a54f7dc2 08-Jul-2011 Ingo Weinhold <ingo_weinhold@gmx.de>

Move B_MIME_STRING_TYPE to <TypeConstants.h>


# 3e292446 08-Jul-2011 Ingo Weinhold <ingo_weinhold@gmx.de>

Move B_MIME_STRING_TYPE to <TypeConstants.h>


# 4a5a077f 24-Oct-2010 Clemens Zeidler <clemens.zeidler@googlemail.com>

Add a private B_ATTR_CHANGE_NOTIFICATION flag to the open query syscall to tell the query to send notifications when an entry attribute changed and the entry stays in the query. Previously you only get created and removed messages, now you can also get updated messages. Only implement it for bfs.
Fix copy right.

# 4a57f843 02-Jun-2010 Ingo Weinhold <ingo_weinhold@gmx.de>

Introduced types [__haiku_]generic_{addr,size}_t which are wide enough for
virtual and physical addresses.

# 9d570af7 24-May-2010 Ingo Weinhold <ingo_weinhold@gmx.de>

Changed the type of the "op" parameter of the fs_vnode_ops::ioctl() hook and
the _kern_ioctl() syscall from ulong to uint32.

# d34daac8 24-May-2010 Ingo Weinhold <ingo_weinhold@gmx.de>

* config/{HaikuConfig.h,types.h}:
- Added macro __HAIKU_ARCH_BITS specifying the architecture bitness (32/64)
(might be more convenient to use than __HAIKU_ARCH_{32,64}_BIT).
- Added macros __HAIKU_ARCH_PHYSICAL_BITS, __HAIKU_ARCH_PHYSICAL_{32,64}_BIT,
and the types __haiku_phys_[s]addr_t. The intention is to use separate
macros and types for virtual and physical addresses, since for some
architectures (e.g. x86 with PAE) those actually differ.
* sys/types.h, BeBuild.h, SupportDefs.h:
- Added types phys_[s]addr_t and respective printf() format macros.
- Added public macros B_HAIKU_BITS, B_HAIKU_PHYSICAL_BITS,
B_HAIKU_PHYSICAL_{32,64}_BIT.

Might break the build under older Haiku installations. Will test next.

# aec945c9 26-Nov-2009 Axel Dörfler <axeld@pinc-software.de>

* Removed the O_* modes that we currently don't and probably won't support
(O_MOUNT, O_EXLOCK, and O_SHLOCK). I only left the non-standard O_TEMPORARY
for the time being (as it shouldn't fool anyone).
* Fixed libutil that already used O_EXLOCK, even though it did not do anything.
* Moved O_NOCACHE, and O_NOFOLLOW to the section with implemented modes.
* Added O_DIRECTORY.

# 318cb33f 26-Nov-2009 Ingo Weinhold <ingo_weinhold@gmx.de>

Undefine B_HAIKU_{32,64}_BIT macros before defining them. Fixes warning when
building on Haiku, since those will be defined already -- by way of the host
platform's <BeBuild.h>, which currently is included by the POSIX headers..

# cf844822 24-Nov-2009 Ingo Weinhold <ingo_weinhold@gmx.de>

* Added B_PRIdTIME and B_PRIiTIME macros (for time_t).
* Added FSSH_[S]SIZE_MAX to headers/private/fs_shell/fssh_types.h.
* Fixed various 64 bit compiler warnings. Nothing too serious, though.

# 2222d055 24-Nov-2009 Ingo Weinhold <ingo_weinhold@gmx.de>

* Introduced new header directory "config", which ATM contains HaikuConfig.h
and types.h. The idea is to provide a basic architecture/compiler
abstraction by defining types and macros that allow the posix/ and os/
headers to be mostly architecture/compiler agnostic.
* Adjusted the posix/ and os/ headers accordingly.
* <SupportDefs.h>: Introduced B_PRI* and B_SCN* macros similar to the PRI*
and SCN* macros defined in <inttypes.h>, just for the BeOS/Haiku [u]int*
types and some POSIX types (e.g. off_t, dev_t, ino_t) that don't have POSIX
macros. Also the B_PRI* and B_SCN* macros are available unconditionally,
unlike the <inttypes.h> macros, which require __STDC_FORMAT_MACROS to be
defined in C++ mode.

# 5b812019 04-Nov-2008 Axel Dörfler <axeld@pinc-software.de>

* Added function block_cache_discard() that flushes blocks from the block cache,
discarding their changes. This functionality currently only works correctly
when no transactions are used.
* Started test application for the block cache, doesn't do anything yet.

# 057f999d 13-Oct-2008 Axel Dörfler <axeld@pinc-software.de>

* Added a flag B_DISK_SYSTEM_SUPPORTS_WRITING to determine whether or not a
file system can write to files before mounting.
* Set the flag for all file systems that actually can write.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28055 a95241bf-73f2-0310-859d-f6bbb57e9c96


# b2ec044c 30-Sep-2008 Axel Dörfler <axeld@pinc-software.de>

* Added stat::st_blocks field as required by POSIX. This also closes ticket
#2261.
* Made at least BFS report it more or less correctly (the attributes are
ignored, though).

# ee1a1571 07-Sep-2008 Ingo Weinhold <ingo_weinhold@gmx.de>

Implemented a simple directory entry cache to speed up path resolution.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27366 a95241bf-73f2-0310-859d-f6bbb57e9c96


# 3c1a3047 04-Aug-2008 Axel Dörfler <axeld@pinc-software.de>

* Added file_cache_is_enabled() function.
* Added file_map_set_mode() function that you can use to keep a whole file
cached. This is needed for the swap file support: FILE_MAP_CACHE_ALL will
not only precache all file_io_vecs when called, but it will also cause all
file_map_translate() calls to fail that would require further caching (ie.
if the file size had changed).
* Updated the fs_shell file map code to the latest one (with several bug fixes).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26785 a95241bf-73f2-0310-859d-f6bbb57e9c96


# 7491000f 03-Aug-2008 Ingo Weinhold <ingo_weinhold@gmx.de>

Added functions file_cache_{disable,enable}(). They allow to disable
actual caching in the file cache, i.e. all reads and writes go directly
to the underlying device. The implementation is not quite complete,
since the VM can still add pages to the cache when the file is mmap()ed,
which can lead to inconsistencies.

# 9f6ae76f 01-Aug-2008 Axel Dörfler <axeld@pinc-software.de>

* Added acquire_vnode() call that you can use to get another reference to an
inode - unlike get_vnode() the busy flag won't prevent you from getting that
reference.
* Changed put_vnode() to return an error in case the vnode couldn't be found.

# f9ae4297 31-Jul-2008 Axel Dörfler <axeld@pinc-software.de>

* Replaced our SinglyLinkedList with one that has a similar interface as the
DoublyLinkedList. Not yet tested.

# 37de5a0d 30-Jul-2008 Axel Dörfler <axeld@pinc-software.de>

* The rw_lock now behaves just like a recursive locker if KDEBUG_RW_LOCK_DEBUG
is defined to 1; this allows asserting the read lock case, too.
* Added ASSERT_{READ|WRITE}_LOCKED_RW_LOCK() macros. The read assertion is only
working when KDEBUG_RW_LOCK_DEBUG is defined to 1, the write assertion works
always.

# 7e3c2024 28-Jul-2008 Ingo Weinhold <ingo_weinhold@gmx.de>

Added fssh_volume_for_vnode() and fssh_do[_iterative]_fd_io() to the
FS shell. The latter two lack an implementation yet, though.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26670 a95241bf-73f2-0310-859d-f6bbb57e9c96


# 78b32dd0 08-Jul-2008 Axel Dörfler <axeld@pinc-software.de>

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

# 589f1a91 07-Jul-2008 Axel Dörfler <axeld@pinc-software.de>

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

# 7ffafac8 05-Apr-2008 Ingo Weinhold <ingo_weinhold@gmx.de>

* Reorganized the FS interface a little:
- 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.

# 16d8ff2d 02-Apr-2008 Axel Dörfler <axeld@pinc-software.de>

* Added a TRANSACTION_IDLE notification that is sent when the transaction
hasn't been used for more than 2 seconds.
* Replaced the block_cache::lock benaphore with a recursive lock, so that
you can call cache functions from within the notification listeners.

# a121b8c8 24-Mar-2008 Axel Dörfler <axeld@pinc-software.de>

* Added a new flag for write stat: B_STAT_SIZE_INSECURE that allows a
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.
* Implemented BFS's Inode::FillGapWithZeros() using this method now.
* Removed extraneous white space.

# 5e2ef462 23-Mar-2008 Axel Dörfler <axeld@pinc-software.de>

the former ones).
* Removed extraneous white space.
* net_server settings are now also updated when the size of the
file changed.

# 5d0afa4e 18-Jan-2008 Axel Dörfler <axeld@pinc-software.de>

* cache_detach_sub_transaction() didn't really work: it did not put all needed
blocks into the new transaction, but it would set that transaction on all
blocks of the old transaction, too. Also, it did not correctly update the
num_blocks/sub_num_blocks fields of the old transaction. Even worse, it did
return B_OK instead of the ID of the new transaction...
* get_writable_cached_block() did not correctly maintain the number of blocks
in the sub transaction.
* 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
of only the main (parent) transaction as well, added new
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.

# 4fc4f2c8 13-Jan-2008 Axel Dörfler <axeld@pinc-software.de>

* Added a transaction listener mechanism to be notified when a
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.

# 21885de2 08-Dec-2007 Axel Dörfler <axeld@pinc-software.de>

* BFS now always writes back the whole block when it writes the super block.
* 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
(this will probably be moved into a disk system API later).
* Added user_memcpy() to the fs_shell.
* Minor cleanup.

# 3d268eda 10-Nov-2007 Axel Dörfler <axeld@pinc-software.de>

* Extracted file_map API out of the file cache - it's now an optional service
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.

# 8c8f8c84 04-Oct-2007 Ingo Weinhold <ingo_weinhold@gmx.de>

Added scan_partition() function which can be used by disk systems (e.g.
in *_initialize()) to save some work.

# 76a8ec23 22-Aug-2007 Ingo Weinhold <ingo_weinhold@gmx.de>

* Added disk system flags for whether a partition name and partition
content name are supported.
* Added file_system_module_info::flags (analogously to
partition_module_info::flags) which indicate which disk device
features the FS supports.
* Replaced the
file_system_module_info/partition_module_info::supports_*()
hooks by a get_supported_operations() hook and for partitioning
systems additionally a get_supported_child_operations() hook.
* Updated file and partitioning systems accordingly.
* Updated fs_shell accordingly.
* Updated the DDM accordingly. The syscall interface remains unchanged,
though.
* _user_supports_initializing_partition() also checks whether the parent
partitioning system is content now.

# a38a92c9 26-Apr-2007 Ingo Weinhold <ingo_weinhold@gmx.de>

Beginnings of a new, better portable FS shell with Haiku FS interface.
Doesn't do anything ATM, but already provides the required system
interface (VFS, caches, POSIX functions).

# efb0a3a853557e69ecf2bc88adc9a69ed08d1514 17-Aug-2015 Michael Lotz <mmlr@mlotz.ch>

EntryCache: Add entry_cache_add_missing() for negative caching.

It provides a way for filesystems to cache a lookup failure and
therefore prevents repeated lookups of missing entries. This is a
common scenario for example in command lookup and compiling, where
each directory in PATH or each include directory is searched for the
given entry.

kernel: atomic_*() functions rework

* No need for the atomically changed variables to be declared as
volatile.
* Drop support for atomically getting and setting unaligned data.
* Introduce atomic_get_and_set[64]() which works the same as
atomic_set[64]() used to. atomic_set[64]() does not return the
previous value anymore.

Add a private B_ATTR_CHANGE_NOTIFICATION flag to the open query syscall to tell the query to send notifications when an entry attribute changed and the entry stays in the query. Previously you only get created and removed messages, now you can also get updated messages. Only implement it for bfs.
Fix copy right.

# d34daac82a58a31e54a076f121c2bbb0cea60447 24-May-2010 Ingo Weinhold <ingo_weinhold@gmx.de>

* config/{HaikuConfig.h,types.h}:
- Added macro __HAIKU_ARCH_BITS specifying the architecture bitness (32/64)
(might be more convenient to use than __HAIKU_ARCH_{32,64}_BIT).
- Added macros __HAIKU_ARCH_PHYSICAL_BITS, __HAIKU_ARCH_PHYSICAL_{32,64}_BIT,
and the types __haiku_phys_[s]addr_t. The intention is to use separate
macros and types for virtual and physical addresses, since for some
architectures (e.g. x86 with PAE) those actually differ.
* sys/types.h, BeBuild.h, SupportDefs.h:
- Added types phys_[s]addr_t and respective printf() format macros.
- Added public macros B_HAIKU_BITS, B_HAIKU_PHYSICAL_BITS,
B_HAIKU_PHYSICAL_{32,64}_BIT.

Might break the build under older Haiku installations. Will test next.

(O_MOUNT, O_EXLOCK, and O_SHLOCK). I only left the non-standard O_TEMPORARY
for the time being (as it shouldn't fool anyone).

Undefine B_HAIKU_{32,64}_BIT macros before defining them. Fixes warning when

* Introduced new header directory "config", which ATM contains HaikuConfig.h
and types.h. The idea is to provide a basic architecture/compiler
abstraction by defining types and macros that allow the posix/ and os/
headers to be mostly architecture/compiler agnostic.
* Adjusted the posix/ and os/ headers accordingly.
* <SupportDefs.h>: Introduced B_PRI* and B_SCN* macros similar to the PRI*
and SCN* macros defined in <inttypes.h>, just for the BeOS/Haiku [u]int*
types and some POSIX types (e.g. off_t, dev_t, ino_t) that don't have POSIX
macros. Also the B_PRI* and B_SCN* macros are available unconditionally,
unlike the <inttypes.h> macros, which require __STDC_FORMAT_MACROS to be
defined in C++ mode.

* Added file_cache_is_enabled() function.
* Added file_map_set_mode() function that you can use to keep a whole file
cached. This is needed for the swap file support: FILE_MAP_CACHE_ALL will
not only precache all file_io_vecs when called, but it will also cause all
file_map_translate() calls to fail that would require further caching (ie.
if the file size had changed).
* Updated the fs_shell file map code to the latest one (with several bug fixes).

# 7491000f2098a73772a5914dc4c4bd62ffd616da 03-Aug-2008 Ingo Weinhold <ingo_weinhold@gmx.de>

Added functions file_cache_{disable,enable}(). They allow to disable
actual caching in the file cache, i.e. all reads and writes go directly
to the underlying device. The implementation is not quite complete,
since the VM can still add pages to the cache when the file is mmap()ed,
which can lead to inconsistencies.

* The rw_lock now behaves just like a recursive locker if KDEBUG_RW_LOCK_DEBUG
is defined to 1; this allows asserting the read lock case, too.
* Added ASSERT_{READ|WRITE}_LOCKED_RW_LOCK() macros. The read assertion is only
working when KDEBUG_RW_LOCK_DEBUG is defined to 1, the write assertion works
always.

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

# 7ffafac8d76aa50ea68667e61038022220a90256 05-Apr-2008 Ingo Weinhold <ingo_weinhold@gmx.de>

* Reorganized the FS interface a little:
- 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.

hasn't been used for more than 2 seconds.

you can call cache functions from within the notification listeners.

* Added a new flag for write stat: B_STAT_SIZE_INSECURE that allows a
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.
* Implemented BFS's Inode::FillGapWithZeros() using this method now.
* Removed extraneous white space.

* Removed extraneous white space.
* net_server settings are now also updated when the size of the
file changed.

Forgot to commit these; this fixes building the fs_shell, thanks Jerome!

* cache_detach_sub_transaction() didn't really work: it did not put all needed
blocks into the new transaction, but it would set that transaction on all
blocks of the old transaction, too. Also, it did not correctly update the
num_blocks/sub_num_blocks fields of the old transaction. Even worse, it did
return B_OK instead of the ID of the new transaction...
* get_writable_cached_block() did not correctly maintain the number of blocks
in the sub transaction.
* 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
of only the main (parent) transaction as well, added new
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.

# 4fc4f2c8aeefd8548dc95f51af64beabc07a4ec5 13-Jan-2008 Axel Dörfler <axeld@pinc-software.de>

* Added a transaction listener mechanism to be notified when a
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.

* BFS now always writes back the whole block when it writes the super block.
* 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
(this will probably be moved into a disk system API later).
* Added user_memcpy() to the fs_shell.
* Minor cleanup.

* Extracted file_map API out of the file cache - it's now an optional service
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.

Added scan_partition() function which can be used by disk systems (e.g.
in *_initialize()) to save some work.

* Added disk system flags for whether a partition name and partition
content name are supported.
* Added file_system_module_info::flags (analogously to
partition_module_info::flags) which indicate which disk device
features the FS supports.
* Replaced the
file_system_module_info/partition_module_info::supports_*()
hooks by a get_supported_operations() hook and for partitioning
systems additionally a get_supported_child_operations() hook.
* Updated file and partitioning systems accordingly.
* Updated fs_shell accordingly.
* Updated the DDM accordingly. The syscall interface remains unchanged,
though.
* _user_supports_initializing_partition() also checks whether the parent
partitioning system is content now.

Beginnings of a new, better portable FS shell with Haiku FS interface.
Doesn't do anything ATM, but already provides the required system
interface (VFS, caches, POSIX functions).
