2734 6111 d 5 h jermar /trunk/uspace/ Support for close().  
2733 6111 d 5 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2718 6125 d 2 h cejka /trunk/uspace/lib/libc/arch/ia32/ Added setjmp and longjmp functions for ia32 architecture.  
2710 6132 d 0 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2708 6132 d 3 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.  
2707 6132 d 4 h jermar /trunk/uspace/ Support for mkdir().  
2705 6132 d 21 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2700 6140 d 6 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 6140 d 20 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 6145 d 23 h jermar /trunk/uspace/lib/libc/ Add opendir(), rewinddir(), closedir() and some prototypes and stubs. Add dirent.h.  
2693 6146 d 6 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2688 6150 d 23 h jermar /trunk/uspace/ Make uspace rwlock API naming conventions consistent with kernel rwlock API.  
2684 6153 d 0 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 6153 d 5 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 6153 d 6 h jermar /trunk/uspace/ Turn the namespace futex into rwlock.  
2680 6153 d 6 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 6159 d 2 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 6159 d 3 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 6159 d 9 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 6159 d 22 h jermar /trunk/uspace/lib/libc/generic/ Actually use the nbyte argument in both read() and write().
Fix warnings in read() and write().
