4605 5609 d 18 h decky /branches/snapshot/ add task snapshoting branch  
4586 5613 d 13 h jermar /trunk/uspace/ Add libfs_stat() and let FAT and TMPFS use it.  
4584 5613 d 18 h jermar /trunk/uspace/ Separate the VFS input and output protocols.  
4484 5638 d 12 h decky /trunk/uspace/lib/libfs/ add libfs_open_node() helper function
cleanup		  
4429 5650 d 13 h jermar /trunk/uspace/ Add fs_handle argument to libfs_mount() needed to recognize homogenous mounts.  
4423 5651 d 14 h jermar /trunk/uspace/lib/libfs/ Answer VFS_MOUNT with return values obtained from VFS_MOUNTED.  
4414 5652 d 1 h decky /trunk/uspace/lib/libfs/ cstyle  
4409 5653 d 10 h jermar /trunk/uspace/ Rudimentary support for non-root mounts.  
4370 5663 d 10 h jermar /trunk/uspace/ Streamline TMPFS and fix its design so that it properly supports hardlinks.
libfs operation unlink() is now passed also the name of the component being
unlinked.		  
4368 5663 d 23 h jermar /trunk/uspace/ Lookup a node's parent lexically rather than using the broken L_PARENT flag of
VFS_LOOKUP.		  
4357 5667 d 10 h jermar /trunk/uspace/ Introduce the concept of FS nodes. A FS node is a typed abstraction of
file-system-specific node type. It replaces the void * in libfs interfaces
and is suitable for holding various information such as mount point data.		  
3625 5830 d 19 h jermar /trunk/uspace/ libfs operation link() should return standard error code instead of mere
true/false.		  
3575 5844 d 11 h jermar /trunk/uspace/ libfs create operation should take the device handle as argument.  
3521 5857 d 15 h jermar /trunk/uspace/ Move libfs_blockread(), block_get() and block_put() to libblock.  
3254 5937 d 17 h jermar /trunk/uspace/ Stop using fixed size BLOCK_SIZE in the ramdisk task and allow each client to negotiate its own
maximum block size. Allow the individual transfers to use block sizes smaller and equal to the
negotiated maximum block size.		  
3252 5938 d 11 h jermar /trunk/uspace/ Add a comment to libfs_blockread() and change type from size_t to off_t at
various places.		  
3251 5938 d 13 h jermar /trunk/uspace/ Move tmpfs_blockread() to libfs and rename it to libfs_blockread().
Add one argument to specify block size.		  
3048 6003 d 19 h decky /trunk/uspace/lib/libfs/ fix typo  
3003 6012 d 12 h jermar /trunk/uspace/lib/libfs/ More of the preivous commit.  
3002 6012 d 12 h jermar /trunk/uspace/lib/libfs/ Optimize conditions in libfs_lookup(). Perform primitive comparisons in the
left-hand subexpression and potentially expensive calls to libfs operations in
the right-hand subexpression.		  
2863 6047 d 21 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2857 6053 d 5 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2852 6054 d 3 h jermar /trunk/uspace/ Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.		  
2847 6055 d 5 h jermar /trunk/uspace/lib/libfs/ Reset the component length variable only prior collecting a new component.  
2846 6055 d 5 h jermar /trunk/uspace/lib/libfs/ Improve libfs_lookup() so that has_children() is not called for each character
in the pathname component.		  
2844 6055 d 9 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2831 6058 d 3 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2792 6065 d 12 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 6068 d 9 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2770 6087 d 11 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2763 6089 d 15 h jermar /trunk/uspace/ Support for rename().  
2760 6092 d 9 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 6093 d 10 h jermar /trunk/uspace/ No need to keep the parent pointer in the TMPFS node. Moreover, other file
systems won't have it either. Finally, if TMPFS is to support hardlinks, there
can be multiple parents.		  
2751 6097 d 15 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2750 6098 d 10 h jermar /trunk/uspace/lib/libfs/ Add a comment to libfs_lookup.  
2747 6100 d 9 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2678 6158 d 15 h jermar /trunk/uspace/ The IPC_M_SHARE_* and IPC_M_DATA_* calls pass through 3 stages. Rename the send,
receive and deliver wrappers to names ending with 'start', 'receive' and
'finalize', respectively. This should make it clearer for dummies.		  
2677 6158 d 15 h jermar /trunk/ Rename IPC_M_AS_AREA_SEND to IPC_M_SHARE_OUT. Rename IPC_M_AS_AREA_RECV to
IPC_M_SHARE_IN. Provide user-friendly wrappers for these methods so that even
dummies can get it right. Some applications using simpler protocols still use
these methods directly.		  
2660 6166 d 12 h jermar /trunk/ Rename IPC_M_DATA_SEND to IPC_M_DATA_WRITE. Now, when we also add
IPC_M_DATA_READ, it will not clash and cause confusion with userspace wrappers
such as ipc_data_receive(). Rename the forementioned wrappers to
ipc_data_write_send(), ipc_data_write_receive() and ipc_data_write_deliver().		  
2643 6173 d 16 h jermar /trunk/uspace/ VFS work.
Move FS registration code to libfs.
