2699 6042 d 17 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.
 
2698 6042 d 22 h jermar /trunk/uspace/srv/vfs/ Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules.
 
2694 6047 d 20 h jermar /trunk/uspace/lib/libc/ Add opendir(), rewinddir(), closedir() and some prototypes and stubs. Add dirent.h.  
2693 6048 d 3 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2691 6051 d 21 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 6052 d 19 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.
 
2689 6052 d 19 h jermar /trunk/uspace/srv/vfs/ Merge all VFS operations into one file.  
2688 6052 d 20 h jermar /trunk/uspace/ Make uspace rwlock API naming conventions consistent with kernel rwlock API.  
2687 6052 d 20 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2686 6052 d 21 h jermar /trunk/uspace/srv/fs/tmpfs/ Previous commit was toxic. When emulating gaps, zero out the reallocated buffer, not the original one.  
2685 6052 d 21 h jermar /trunk/uspace/srv/fs/tmpfs/ TMPFS must handle file gaps.  
2684 6054 d 21 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 6055 d 0 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 6055 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 6055 d 3 h jermar /trunk/uspace/ Turn the namespace futex into rwlock.  
2680 6055 d 4 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 6058 d 20 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.
 
2678 6060 d 23 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 6061 d 0 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.
 
2676 6061 d 6 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.
 
2675 6061 d 19 h jermar /trunk/uspace/lib/libc/generic/ Actually use the nbyte argument in both read() and write().
Fix warnings in read() and write().
 
2674 6061 d 19 h jermar /trunk/uspace/ Add libc VFS wrapper for VFS_WRITE. Fix a small bug in read(). Place open(),
read() and write() declarations in their respective headers according to SUSv3.
 
2673 6061 d 19 h jermar /trunk/uspace/srv/fs/tmpfs/ Rename variable from 'size' to 'len'.  
2672 6061 d 19 h jermar /trunk/uspace/app/tester/vfs/ Use libc's VFS wrappers instead of direct communication with VFS.  
2671 6061 d 19 h jermar /trunk/uspace/lib/libc/ Add VFS wrappers for VFS_MOUNT, VFS_OPEN and VFS_READ to libc.  
2670 6065 d 18 h jermar /trunk/uspace/ Move the open(), read() and write() provided by streams.c away so that
these functions won't clash with the real open(), read() and write(), which are
soon to be provided by a libvfs library. Applications can now use open_stdin(),
open_stdout(), read_stdin() and write_stdout(). Later, there might be an option
of providing a custom console file system, which will work similarly to how
streams' open(), read() and write() worked.
 
2669 6065 d 19 h jermar /trunk/uspace/lib/libc/generic/io/ Remove file.c.  
2668 6065 d 19 h jermar /trunk/uspace/lib/libc/include/io/ Remove file.h.  
2667 6066 d 16 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 6066 d 20 h jermar /trunk/uspace/srv/ VFS and TMPFS support for VFS_WRITE.  
2665 6068 d 18 h jermar /trunk/uspace/app/tester/vfs/ The vfs1 test now reads a file on a TMPFS file system.  
2664 6068 d 18 h jermar /trunk/uspace/srv/fs/tmpfs/ Fix two bugs in TMPFS-side VFS_READ.  
2663 6068 d 19 h jermar /trunk/uspace/ Reimplement VFS_READ using IPC_M_DATA_READ.  
2662 6068 d 19 h jermar /trunk/ Add support for IPC_M_DATA_READ calls.  
2660 6068 d 21 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().
 
2659 6069 d 17 h jermar /trunk/uspace/srv/vfs/ After VFS_READ, update the position pointer in the open file.  
2658 6069 d 18 h jermar /trunk/uspace/srv/ VFS work.
Foundation for TMPFS-side VFS_READ and fixes in VFS-side VFS_READ.
 
2657 6069 d 20 h jermar /trunk/uspace/ VFS work.
Cleaner VFS_MOUNT protocol.
 
2656 6073 d 0 h jermar /trunk/uspace/app/tester/ Add a simple test of VFS_MOUNT and VFS_OPEN to tester.  
2655 6073 d 0 h jermar /trunk/uspace/srv/fs/tmpfs/ TMPFS work.
VFS_LOOKUP implemented.
