4377 5706 d 20 h svoboda /branches/tracing/ Merge latest trunk changes to tracing. (i.e. revs 3684:4374, huge). This time hopefully the real thing.  
3675 5863 d 18 h svoboda /branches/tracing/ Merge latest trunk changes to tracing.  
3425 5944 d 6 h svoboda /branches/tracing/ Merge latest trunk changes into tracing (broken)  
3424 5944 d 18 h svoboda /branches/tracing/ Merge trunk changes up to r3180 into tracing  
2925 6068 d 7 h svoboda /branches/tracing/ Merged latest trunk changes to tracing branch  
2787 6116 d 23 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2770 6132 d 19 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2766 6134 d 20 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 6134 d 23 h jermar /trunk/uspace/ Support for rename().  
2752 6142 d 1 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2742 6147 d 17 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 6155 d 23 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 6156 d 1 h jermar /trunk/uspace/ Support for close().  
2731 6156 d 2 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 6157 d 4 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2709 6176 d 23 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2707 6177 d 1 h jermar /trunk/uspace/ Support for mkdir().  
2704 6178 d 4 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2700 6185 d 2 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 6191 d 3 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2691 6194 d 20 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 6195 d 18 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 6195 d 19 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2684 6197 d 20 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 6197 d 23 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 6198 d 2 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 6198 d 3 h jermar /trunk/uspace/ Turn the namespace futex into rwlock.  
2680 6198 d 3 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 6201 d 19 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 6209 d 20 h jermar /trunk/uspace/srv/ VFS and TMPFS support for VFS_WRITE.  
2641 6220 d 22 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 6240 d 21 h jermar /trunk/uspace/srv/vfs/ VFS work.
Proto implementation of VFS_READ.
 
2596 6258 d 22 h jermar /trunk/uspace/srv/vfs/ VFS work.
Implement VFS node hash table management.
 
2593 6260 d 20 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 6261 d 23 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.
 
2589 6262 d 0 h jermar /trunk/uspace/srv/vfs/ VFS work.

Allocate the open filess array dynamically and protect access to it via a
per-connection futex. Defer its allocation until the client makes a first
VFS_OPEN request.

Actually call vfs_mount() and vfs_open(), respectively, when the VFS_MOUNT and
VFS_OPEN requests, respectively, are received from the client.
 
2587 6262 d 1 h jermar /trunk/uspace/srv/vfs/ VFS work.
Introduce the notion of VFS_PAIR which corresponds to a file system instance,
and VFS_TRIPLET, which corresponds to a file system node. Separate vfs_triplet_t
and vfs_node_t as the former one is the stateless counterpart of the latter.
 
2560 6296 d 22 h jermar /trunk/uspace/srv/vfs/ VFS work.
Start VFS_OPEN.
 
2552 6297 d 20 h jermar /trunk/uspace/srv/vfs/ VFS work.
This is a checkpoint commit.
It introduces initial, still incomplete, code for VFS-side VFS_MOUNT request.
