2758 5954 d 16 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 5957 d 13 h jermar /trunk/uspace/ Add support for relative paths: chdir() and getcwd().  
2754 5957 d 13 h jermar /trunk/uspace/lib/libc/ Add strcat().  
2753 5957 d 16 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2751 5958 d 21 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.
 
2750 5959 d 16 h jermar /trunk/uspace/lib/libfs/ Add a comment to libfs_lookup.  
2747 5961 d 15 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2745 5962 d 2 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2741 5967 d 17 h jermar /trunk/uspace/lib/libc/generic/ Prevent read() and write() from returning an uninitialized error return value.  
2735 5971 d 21 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 5971 d 23 h jermar /trunk/uspace/ Support for close().  
2733 5971 d 23 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2718 5985 d 20 h cejka /trunk/uspace/lib/libc/arch/ia32/ Added setjmp and longjmp functions for ia32 architecture.  
2710 5992 d 19 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2708 5992 d 21 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.  
2707 5992 d 23 h jermar /trunk/uspace/ Support for mkdir().  
2705 5993 d 15 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2700 6001 d 0 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 6001 d 14 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 6006 d 17 h jermar /trunk/uspace/lib/libc/ Add opendir(), rewinddir(), closedir() and some prototypes and stubs. Add dirent.h.  
2693 6007 d 0 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2688 6011 d 17 h jermar /trunk/uspace/ Make uspace rwlock API naming conventions consistent with kernel rwlock API.  
2684 6013 d 18 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 6014 d 0 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 6014 d 1 h jermar /trunk/uspace/ Turn the namespace futex into rwlock.  
2680 6014 d 1 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 6019 d 20 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 6019 d 21 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 6020 d 3 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 6020 d 16 h jermar /trunk/uspace/lib/libc/generic/ Actually use the nbyte argument in both read() and write().
Fix warnings in read() and write().
 
2674 6020 d 16 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 6020 d 17 h jermar /trunk/uspace/lib/libc/ Add VFS wrappers for VFS_MOUNT, VFS_OPEN and VFS_READ to libc.  
2670 6024 d 15 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 6024 d 16 h jermar /trunk/uspace/lib/libc/generic/io/ Remove file.c.  
2668 6024 d 16 h jermar /trunk/uspace/lib/libc/include/io/ Remove file.h.  
2663 6027 d 16 h jermar /trunk/uspace/ Reimplement VFS_READ using IPC_M_DATA_READ.  
2662 6027 d 16 h jermar /trunk/ Add support for IPC_M_DATA_READ calls.  
2660 6027 d 18 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().
 
2644 6034 d 20 h jermar /trunk/uspace/ Move incomplete fs interface from fat.h to libfs.  
2643 6034 d 21 h jermar /trunk/uspace/ VFS work.
Move FS registration code to libfs.
