2699 5960 d 8 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.
 
2694 5965 d 11 h jermar /trunk/uspace/lib/libc/ Add opendir(), rewinddir(), closedir() and some prototypes and stubs. Add dirent.h.  
2693 5965 d 18 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2688 5970 d 11 h jermar /trunk/uspace/ Make uspace rwlock API naming conventions consistent with kernel rwlock API.  
2684 5972 d 12 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).
 
2682 5972 d 18 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 5972 d 19 h jermar /trunk/uspace/ Turn the namespace futex into rwlock.  
2680 5972 d 19 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.
 
2678 5978 d 14 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 5978 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.
 
2676 5978 d 21 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 5979 d 10 h jermar /trunk/uspace/lib/libc/generic/ Actually use the nbyte argument in both read() and write().
Fix warnings in read() and write().
 
2674 5979 d 10 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.
 
2671 5979 d 11 h jermar /trunk/uspace/lib/libc/ Add VFS wrappers for VFS_MOUNT, VFS_OPEN and VFS_READ to libc.  
2670 5983 d 9 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 5983 d 10 h jermar /trunk/uspace/lib/libc/generic/io/ Remove file.c.  
2668 5983 d 10 h jermar /trunk/uspace/lib/libc/include/io/ Remove file.h.  
2663 5986 d 10 h jermar /trunk/uspace/ Reimplement VFS_READ using IPC_M_DATA_READ.  
2662 5986 d 10 h jermar /trunk/ Add support for IPC_M_DATA_READ calls.  
2660 5986 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().
