2857 6023 d 14 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2852 6024 d 12 h jermar /trunk/uspace/ Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.

2844 6025 d 19 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2831 6028 d 12 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2792 6035 d 22 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 6038 d 19 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2770 6057 d 21 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2763 6060 d 0 h jermar /trunk/uspace/ Support for rename().  
2760 6062 d 19 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 6063 d 19 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.
 
2757 6063 d 21 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 6063 d 22 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2747 6070 d 19 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 6072 d 19 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().
 
2739 6078 d 19 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 6080 d 21 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 6081 d 1 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2733 6081 d 3 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 6081 d 3 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 6081 d 4 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 6082 d 6 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 6086 d 19 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 6101 d 22 h jermar /trunk/uspace/ Remove the debugging hack from tmpfs_init(), which created several files and
directories on the filesystem. TMPFS is now self-sufficient enough to be able
to create its content via the standard VFS interface.
 
2710 6101 d 23 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2707 6102 d 3 h jermar /trunk/uspace/ Support for mkdir().  
2706 6102 d 7 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.
 
2705 6102 d 19 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2700 6110 d 4 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).
 
2699 6110 d 18 h jermar /trunk/uspace/ Finish implementation of readdir(). Functions from this family are implemented
via using file descriptors for directories. For example, readdir() is
implemented as read() from an open directory. Of course, FS implementations
must understand that they are asked to read a directory and behave accordingly.
 
2693 6116 d 4 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2690 6120 d 20 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 6120 d 21 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2686 6120 d 22 h jermar /trunk/uspace/srv/fs/tmpfs/ Previous commit was toxic. When emulating gaps, zero out the reallocated buffer, not the original one.  
2685 6120 d 22 h jermar /trunk/uspace/srv/fs/tmpfs/ TMPFS must handle file gaps.  
2678 6129 d 0 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.
 
2676 6129 d 7 h jermar /trunk/ Simplify the IPC_M_DATA_WRITE protocol. Do not pass the source address space
virtual address to the recipient. This feature was not used anyway. Now
IPC_M_DATA_WRITE and IPC_M_DATA_READ are feature-aligned.
 
2673 6129 d 20 h jermar /trunk/uspace/srv/fs/tmpfs/ Rename variable from 'size' to 'len'.  
2667 6134 d 17 h jermar /trunk/uspace/srv/fs/tmpfs/ The previous commit was not entirely sane.
Handle VFS_WRITE correctly when the file doesn't grow.
Handle it correctly also when the file grows.
 
2666 6134 d 21 h jermar /trunk/uspace/srv/ VFS and TMPFS support for VFS_WRITE.  
2664 6136 d 19 h jermar /trunk/uspace/srv/fs/tmpfs/ Fix two bugs in TMPFS-side VFS_READ.
