2781 5988 d 11 h cejka /trunk/ Unified context saving/restoring macros in ppc32.  
2780 5988 d 12 h cejka /trunk/ Fixed broken context_offset.h symlinks for mips32eb and ia32xen.  
2779 5988 d 12 h cejka /trunk/ Context saving/restoring macros used for mips32.  
2778 5988 d 13 h jermar /trunk/uspace/lib/libc/arch/ia32/src/ Fix jmp_buf vs. context structure in comment.  
2777 5988 d 14 h cejka /trunk/ Unified context handling code for amd64.  
2776 5988 d 14 h cejka /trunk/uspace/lib/libc/arch/ia32/src/ Context saving/restoring code replaced with macro.  
2773 5988 d 15 h cejka /trunk/uspace/lib/libc/ United headers using context_t in uspace.  
2771 5992 d 3 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 5992 d 4 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2763 5994 d 7 h jermar /trunk/uspace/ Support for rename().  
2762 5994 d 7 h jermar /trunk/uspace/lib/libc/include/ Add the definition of the EXDEV error code.  
2761 5995 d 12 h jermar /trunk/uspace/lib/libc/generic/vfs/ mkdir() and _unlink() should return the real return code.  
2760 5997 d 2 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2759 5997 d 2 h jermar /trunk/uspace/lib/libc/ Add hash_table_destroy().  
2758 5998 d 2 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 6001 d 0 h jermar /trunk/uspace/ Add support for relative paths: chdir() and getcwd().  
2754 6001 d 0 h jermar /trunk/uspace/lib/libc/ Add strcat().  
2753 6001 d 3 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2751 6002 d 7 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.
 
2750 6003 d 2 h jermar /trunk/uspace/lib/libfs/ Add a comment to libfs_lookup.  
2747 6005 d 1 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2745 6005 d 12 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2741 6011 d 3 h jermar /trunk/uspace/lib/libc/generic/ Prevent read() and write() from returning an uninitialized error return value.  
2735 6015 d 8 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 6015 d 9 h jermar /trunk/uspace/ Support for close().  
2733 6015 d 10 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2718 6029 d 7 h cejka /trunk/uspace/lib/libc/arch/ia32/ Added setjmp and longjmp functions for ia32 architecture.  
2710 6036 d 5 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2708 6036 d 8 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.  
2707 6036 d 9 h jermar /trunk/uspace/ Support for mkdir().  
2705 6037 d 2 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2700 6044 d 11 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 6045 d 0 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 6050 d 4 h jermar /trunk/uspace/lib/libc/ Add opendir(), rewinddir(), closedir() and some prototypes and stubs. Add dirent.h.  
2693 6050 d 11 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2688 6055 d 3 h jermar /trunk/uspace/ Make uspace rwlock API naming conventions consistent with kernel rwlock API.  
2684 6057 d 5 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 6057 d 10 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 6057 d 11 h jermar /trunk/uspace/ Turn the namespace futex into rwlock.  
2680 6057 d 11 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.
