2773 5977 d 13 h cejka /trunk/uspace/lib/libc/ United headers using context_t in uspace.  
2771 5981 d 0 h jermar /trunk/uspace/lib/libc/generic/vfs/ Simplify the libc procedure needed to convert a user-supplied path to an
absolute canonical path.		  
2770 5981 d 1 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2763 5983 d 4 h jermar /trunk/uspace/ Support for rename().  
2762 5983 d 5 h jermar /trunk/uspace/lib/libc/include/ Add the definition of the EXDEV error code.  
2761 5984 d 10 h jermar /trunk/uspace/lib/libc/generic/vfs/ mkdir() and _unlink() should return the real return code.  
2760 5985 d 23 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2759 5985 d 23 h jermar /trunk/uspace/lib/libc/ Add hash_table_destroy().  
2758 5986 d 23 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.		  
2755 5989 d 21 h jermar /trunk/uspace/ Add support for relative paths: chdir() and getcwd().  
2754 5989 d 21 h jermar /trunk/uspace/lib/libc/ Add strcat().  
2753 5990 d 0 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2751 5991 d 5 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2750 5992 d 0 h jermar /trunk/uspace/lib/libfs/ Add a comment to libfs_lookup.  
2747 5993 d 23 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2745 5994 d 10 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2741 6000 d 1 h jermar /trunk/uspace/lib/libc/generic/ Prevent read() and write() from returning an uninitialized error return value.  
2735 6004 d 5 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 6004 d 7 h jermar /trunk/uspace/ Support for close().  
2733 6004 d 7 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2718 6018 d 4 h cejka /trunk/uspace/lib/libc/arch/ia32/ Added setjmp and longjmp functions for ia32 architecture.  
2710 6025 d 3 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2708 6025 d 5 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.  
2707 6025 d 7 h jermar /trunk/uspace/ Support for mkdir().  
2705 6025 d 23 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2700 6033 d 8 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 6033 d 22 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 6039 d 1 h jermar /trunk/uspace/lib/libc/ Add opendir(), rewinddir(), closedir() and some prototypes and stubs. Add dirent.h.  
2693 6039 d 8 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2688 6044 d 1 h jermar /trunk/uspace/ Make uspace rwlock API naming conventions consistent with kernel rwlock API.  
2684 6046 d 2 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 6046 d 8 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 6046 d 9 h jermar /trunk/uspace/ Turn the namespace futex into rwlock.  
2680 6046 d 9 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 6052 d 4 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 6052 d 5 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 6052 d 11 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 6053 d 0 h jermar /trunk/uspace/lib/libc/generic/ Actually use the nbyte argument in both read() and write().
Fix warnings in read() and write().		  
2674 6053 d 0 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 6053 d 1 h jermar /trunk/uspace/lib/libc/ Add VFS wrappers for VFS_MOUNT, VFS_OPEN and VFS_READ to libc.
