bfs: Update old modified time if index is missing.

* This is required to avoid spurious last modified time change
notifications on file systems without index.
* This closes ticket #9834.

bfs: Use the QueryParserUtils instead of its own copy.

* Ingo copied the methods into a shared location, and then obviously
"forgot" to let BFS use them. As a side note for Ingo: the complete
error GCC reported was "std::fssh_size_t" not defined with the macro
wrapper as code location. The actual problem was a "using std::size_t"
in some C++ header that accidentally got included after the wrapper.
* The shared Query code is not yet used. That'll be done another time.
* Renamed BFS_SHELL define to FS_SHELL, such that QueryParserUtils can be
used in any file system shell, not just the bfs_shell.

Move B_MIME_STRING_TYPE to <TypeConstants.h>

Move B_MIME_STRING_TYPE to <TypeConstants.h>

* Got rid of the type == 0 feature in Update(); it does not really serve any
purpose anymore, and was just confusing.
* Minor cleanup.

* Replaced the Inode::GetTree() method with a simple getter - the tree is
always created for directories since quite some time now.

* Cleanup of how the time is converted between bfs_inode and the outside world:
there is now a couple of conversion functions, and I changed the type from
bigtime_t to int64, as it's not what a bigtime_t would usually contain, but
some shift magic in order to make duplicate index entries less likely.
* We now correctly fill in the timespec in struct stat as good as possible; the
12 of the 16 possible bits are used for the nano second value. The lower 8
bits are used to avoid the duplicate index entries. Only if the nano second
time is 0, the lower 12 bits are used to achieve that.

* Some index updating functions did not take into account that not all nodes
are put into all indices. For example, symlinks aren't part of the size
index. This fixes bug #2704.
* Also, Inode::NeedsTrimming() now ignores symlinks that have no data stream,
it's const now, too.
* Added helper methods Inode::In{Name|Size|LastModified}Index(), and use it
where appropriate.
* Clarified Inode::Create() description with regards to name vs. parent.

* Coding style cleanups, no functional changes.

* Changed the inode write locking to be held as long as the transaction is
running - this fixes several cases where someone could see outdated data
when a transaction had to be reverted (the time between unlocking the inode
and actually reverting the blocks). For that, Inodes can now be put into a
singly linked list.
* Added a TODO in Inode::WriteAt() which explains why it cannot use the above
method: seems that our VFS/VM locking model isn't really that good.
* Fixed a possible deadlock in Attribute::_Truncate() where the inode write
lock was held before starting the transaction.
* Added an InodeReadLocker convenience class, that should be used instead
of ReadLocker - Inode::Lock() only still exists because of the needs of
bfs_io().
* Moved the bfs_io() callback hooks out of the exported module API region,
and removed their bfs_ prefix.
* Added a Volume::IsInitializing() method that should be used rather than
checking if Volume::ID() is >= 0.
* Removed the MultiInodeLocker again, as it's pretty much superfluous now.
* Moved openModeToAccess() to the Utility.h header.
* Minor cleanup.

First round of locking fixes:
* Moved locking the data stream out of the BPlusTree methods; this fixes at
least two locations where another thread could have seen outdated/incorrect
data.
* Removed some superfluous code in bfs_rename(): we don't have to revert to the
previous situation, the transaction does this for us automatically.
* Added a simple MultiWriteLocker, even though it's not really necessary anymore
(since we always hold the transaction lock first when we lock more than one
inode at a time).
* Inode::Create() called InodeAllocator::Keep() a bit too early, the file cache
and map wasn't created and assigned yet.
* InodeAllocator now keeps the inode write locked.

* Replaced BFS's ReadWriteLock implementation with the kernel's rw_lock.
* The BlockAllocator now uses the new mutex_transfer_lock() function instead
of clobbering the mutex directly.
* Removed Lock.h - it's no longer needed.
* Minor white space cleanup.

* 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.

* Inode::Create() now has a "_created" parameter that will be set to true in case a
node has been created - this is now used in bfs_create() to suppress the new entry
notification in case the file already existed.
* Implemented parameter parsing in bfs_initialize() - does not work in the new bfs_shell
though, as it currently misses driver_settings functionality.
* Attribute::Create() and Attribute::Open() will now honour O_TRUNC correctly.
* Note: Inode::WriteAttribute() still follows R5 semantics for small_data attributes
in this regard and must be fixed (I've opened ticket #1242 for this).
* Some cleanup.

* Prepared the BFS sources to be used with the new FS shell:
- Moved all inclusions of system headers into a new
system_dependencies.h header, which conditionally either includes
these or the FS shell headers.
- Fixed compiler warnings related to printf-like functions (int32 is
int, not long on non-BeOS platforms).
* Build a new bfs_shell. Compiles and links, but does nothing ATM.

* Changed Inode::WriteAttribute() so that it no longer reads from the old
attribute when its size was 0 - this also fixes calling Index::Update()
with invalid values, and therefore bug #1178.
* Style cleanup: honour 80 column limit a bit more, use doxygen style comments.

We don't want to drop into the kernel debugger for that right now
(FATAL() would be okay, but it's currently configured to panic).

Big update while moving over completely to the Haiku kernel:
- Ported over BFS to the new cache API
- Inode no longer inherits from CachedBlock, and therefore, no longer
keeps the whole inode block in memory. It now has a copy of the bfs_inode
structure in memory instead. This has a number of advantages but also some
disadvantages, so it might be reverted later, even if it's unlikely.
- Added a NodeGetter class that can be used whenever the real block needs
to be accessed (ie. for attributes)
- Changed *transaction to &transaction where possible
- Removed support for KEEP_WRONG_DIRENT_RECLEN
- Removed support for uncached file access since that's no longer needed
- Fixed some endian issues in bfs_write_stat()
- Removed the install BFS rules, since they don't make any sense anymore
(unless you are running Haiku ;-))

Note, logged streams are not supported anymore right now. Also, the
transaction code is pretty simple and slow - it will be improved later
on. Attribute code is pretty much untested in the new environment.

It's now <util/kernel_cpp.h> rather than <kernel_cpp.h>.
Forgot to commit that...


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7442 a95241bf-73f2-0310-859d-f6bbb57e9c96

Switched from direct get_vnode() usage to the Vnode class.
Now acquires the volume lock always before get_vnode() is called as long
as UNSAFE_GET_VNODE is defined (which now is by default).
May cause some unwanted side-effects; it still has to be thorougly tested.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6424 a95241bf-73f2-0310-859d-f6bbb57e9c96

Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6404 a95241bf-73f2-0310-859d-f6bbb57e9c96

Switched to kernel_cpp.h/cpp.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6291 a95241bf-73f2-0310-859d-f6bbb57e9c96

We forgot about the B_MIME_STRING_TYPE when creating indices and the BEOS:APP_SIG index was failing to be created. It looks the registrar calls the index creation with that type although it is not directly available in the command line tool mkindex, for example.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6274 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed queries a bit more (maybe even completely...). In several situations,
the old attribute value wasn't evaluated at all.
Also, Index::Update() got a type code of zero, instead of the real value
in situations where this didn't make any sense.
Minor cleanup in kernel_interface.cpp.
New method Volume::CheckForLiveQuery() that checks if there is a live query
depending on the specified attribute - not yet implemented, but already used;
always returns "true" right now, which doesn't cause any harm but reducing
the speed lightly.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3394 a95241bf-73f2-0310-859d-f6bbb57e9c96

Index::SetTo() now sets fName even if the index initialization failed (for
whatever reason).
Index::Update() is now allowed to be called for those indices - in this case
it will just update all live queries.
Added some comments.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3329 a95241bf-73f2-0310-859d-f6bbb57e9c96

Style clean-ups *and* Index::Update() now correctly converts B_MIME_STRING_TYPE
to B_STRING_TYPE for the lower layers - should probably find a better solution
to handle this.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2166 a95241bf-73f2-0310-859d-f6bbb57e9c96

Switched from Inode::IsDirectory() to Inode::IsContainer() where necessary.
Now makes use of the changed Inode::Create() logic.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2031 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed a bug that could lead to the wrong last_modified time in an inode;
bfs_close() updated the last_modified time & index, but it didn't write
the inode back to disk.
Furthermore, bfs_write() should have already updated the last_modified
time, not bfs_close.

* Replaced BFS's ReadWriteLock implementation with the kernel's rw_lock.
* The BlockAllocator now uses the new mutex_transfer_lock() function instead
of clobbering the mutex directly.
* Removed Lock.h - it's no longer needed.
* Minor white space cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26317 a95241bf-73f2-0310-859d-f6bbb57e9c96

* 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

* 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.

* Build a new bfs_shell. Compiles and links, but does nothing ATM.

* Changed Inode::WriteAttribute() so that it no longer reads from the old
attribute when its size was 0 - this also fixes calling Index::Update()
with invalid values, and therefore bug #1178.
* Style cleanup: honour 80 column limit a bit more, use doxygen style comments.

Added some ASSERTs that the Index::Update*/Insert*/Remove*() methods are used
only for inodes that maintain those indices.

fix for changes in revision 16498, pointed by Marcus


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16502 a95241bf-73f2-0310-859d-f6bbb57e9c96

added error tracing to help on bug #106

We don't want to drop into the kernel debugger for that right now
(FATAL() would be okay, but it's currently configured to panic).

Big update while moving over completely to the Haiku kernel:
- Ported over BFS to the new cache API
- Inode no longer inherits from CachedBlock, and therefore, no longer
keeps the whole inode block in memory. It now has a copy of the bfs_inode
structure in memory instead. This has a number of advantages but also some
disadvantages, so it might be reverted later, even if it's unlikely.
- Added a NodeGetter class that can be used whenever the real block needs
to be accessed (ie. for attributes)
- Changed *transaction to &transaction where possible
- Removed support for KEEP_WRONG_DIRENT_RECLEN
- Removed support for uncached file access since that's no longer needed
- Fixed some endian issues in bfs_write_stat()
- Removed the install BFS rules, since they don't make any sense anymore
(unless you are running Haiku ;-))

Note, logged streams are not supported anymore right now. Also, the
transaction code is pretty simple and slow - it will be improved later
on. Attribute code is pretty much untested in the new environment.

It's now <util/kernel_cpp.h> rather than <kernel_cpp.h>.
Forgot to commit that...


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7442 a95241bf-73f2-0310-859d-f6bbb57e9c96

Switched from direct get_vnode() usage to the Vnode class.
Now acquires the volume lock always before get_vnode() is called as long
as UNSAFE_GET_VNODE is defined (which now is by default).
May cause some unwanted side-effects; it still has to be thorougly tested.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6424 a95241bf-73f2-0310-859d-f6bbb57e9c96

Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6404 a95241bf-73f2-0310-859d-f6bbb57e9c96

Switched to kernel_cpp.h/cpp.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6291 a95241bf-73f2-0310-859d-f6bbb57e9c96

We forgot about the B_MIME_STRING_TYPE when creating indices and the BEOS:APP_SIG index was failing to be created. It looks the registrar calls the index creation with that type although it is not directly available in the command line tool mkindex, for example.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6274 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed queries a bit more (maybe even completely...). In several situations,
the old attribute value wasn't evaluated at all.
Also, Index::Update() got a type code of zero, instead of the real value
in situations where this didn't make any sense.
Minor cleanup in kernel_interface.cpp.
New method Volume::CheckForLiveQuery() that checks if there is a live query
depending on the specified attribute - not yet implemented, but already used;
always returns "true" right now, which doesn't cause any harm but reducing
the speed lightly.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3394 a95241bf-73f2-0310-859d-f6bbb57e9c96

Index::SetTo() now sets fName even if the index initialization failed (for
whatever reason).
Index::Update() is now allowed to be called for those indices - in this case
it will just update all live queries.
Added some comments.

Style clean-ups *and* Index::Update() now correctly converts B_MIME_STRING_TYPE
to B_STRING_TYPE for the lower layers - should probably find a better solution
to handle this.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2166 a95241bf-73f2-0310-859d-f6bbb57e9c96

Switched from Inode::IsDirectory() to Inode::IsContainer() where necessary.
Now makes use of the changed Inode::Create() logic.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2031 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed a bug that could lead to the wrong last_modified time in an inode;
bfs_close() updated the last_modified time & index, but it didn't write
the inode back to disk.
Furthermore, bfs_write() should have already updated the last_modified
time, not bfs_close.
