2927 5858 d 11 h decky /branches/dynload/ added dynload branch  
2821 5895 d 19 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2770 5923 d 0 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2766 5925 d 1 h jermar /trunk/uspace/srv/vfs/ Grab the nodes_futex when manipulating node link counts in rename() and
_unlink().

Fix VFS futex definitions and declarations by replacing atomic_t by futex_t.
 
2763 5925 d 3 h jermar /trunk/uspace/ Support for rename().  
2752 5932 d 6 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2742 5937 d 22 h jermar /trunk/uspace/srv/ Separate creation of a TMPFS node and its linking in the file system name space.
Rename VFS_FREE to VFS_DESTROY and destroy_node() to unlink_node().
 
2735 5946 d 4 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 5946 d 6 h jermar /trunk/uspace/ Support for close().  
2731 5946 d 7 h jermar /trunk/uspace/srv/ Add the VFS_FREE operation. This operation frees up whatever resources used by
a file system node for which there is no name (i.e. an unlinked node).

Cleanup VFS operations enums and remove unneeded VFS operations.
 
2730 5947 d 9 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2709 5967 d 4 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2707 5967 d 6 h jermar /trunk/uspace/ Support for mkdir().  
2704 5968 d 9 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2700 5975 d 7 h jermar /trunk/uspace/ Introduce the notion of lflag (i.e. lookup flags) to support the ability to
limit the scope of VFS node types that can be opened by open() and opendir(). In
the future, lflag will also specify actions for VFS_LOOKUP handlers that will be
carried out in situations such as the VFS node is not found (e.g. implementation
of mkdir() and open() with O_CREAT in oflag).
 
2693 5981 d 7 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2691 5985 d 1 h jermar /trunk/uspace/srv/vfs/ Improve the API for converting (VFS triplets, size) to VFS nodes by introducing
a new type for results of vfs_lookup_internal().
 
2690 5985 d 23 h jermar /trunk/uspace/srv/ Make a distinction between VFS operations that are common to VFS and FS
implementations, operations that are VFS only and operations that are FS
implementations only.
 
2687 5986 d 0 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2684 5988 d 1 h jermar /trunk/ Add libc and VFS implementation of lseek(), VFS_SEEK resp.
Add the size member to the VFS node structure (not yet initialized).
 
2683 5988 d 4 h jermar /trunk/uspace/srv/vfs/ Introduce the open file lock. Modify vfs_rdwr() to take this lock into account
when reading or writing from/to an open file.
 
2682 5988 d 7 h jermar /trunk/uspace/ Fix type in declaration of VFS node rwlock.
Introduce a dedicated type for futexes. Make the existing futex code use this
newly introduced type and fix formatting in futex.c.
 
2681 5988 d 8 h jermar /trunk/uspace/ Turn the namespace futex into rwlock.  
2680 5988 d 8 h jermar /trunk/uspace/ Add basic rwlock API for uspace so that VFS can be designed/implemented using
this API. So far, the implementation of this API merely wraps futexes into
rwlocks. Real rwlocks are wanted by ticket #54.

Using the new rwlock API, replace the VFS node content futex with an rwlock.
Lock the contents rwlock as reader on reads and as writer on writes.
 
2679 5992 d 0 h jermar /trunk/uspace/srv/vfs/ Rename unlink_futex to namespace_futex and introduce a new futex for serializing
concurrent access to a VFS node's contents by multiple clients.
 
2666 6000 d 1 h jermar /trunk/uspace/srv/ VFS and TMPFS support for VFS_WRITE.  
2641 6011 d 3 h jermar /trunk/uspace/srv/vfs/ VFS work.
During VFS_REGISTER, use strncmp() instead of strcmp().
Add one excessive convenience byte to vfs_info.name to support the
above-mentioned change. In case the fs name spans all available
characters, make sure this convenience byte is zero.
 
2625 6031 d 2 h jermar /trunk/uspace/srv/vfs/ VFS work.
Proto implementation of VFS_READ.
 
2596 6049 d 3 h jermar /trunk/uspace/srv/vfs/ VFS work.
Implement VFS node hash table management.
 
2593 6051 d 1 h jermar /trunk/uspace/srv/vfs/ A lot of more VFS prototyping.
VFS_OPEN gets reasonably complete, fix a limitation that prevented file
structures from being shared by multiple file descriptors, add functions for
file descriptor management, introduce unlink_futex and two new VFS operations
VFS_UNLINK and VFS_RENAME.
 
2590 6052 d 3 h jermar /trunk/uspace/srv/vfs/ VFS work.
Start implementing VFS side of VFS_OPEN.
Add vfs_node.c to contain VFS node related internal functions.
