6060 d 18 h
jermar
/trunk/uspace/srv/vfs/
Make VFS canonify path names on lookup.
2742
6066 d 11 h
jermar
/trunk/uspace/srv/
Separate creation of a TMPFS node and its linking in the file system name space.
Rename VFS_FREE to VFS_DESTROY and destroy_node() to unlink_node().
2735
6074 d 17 h
jermar
/trunk/uspace/
Support for rmdir(), unlink() and the respective VFS operations.
2734
6074 d 18 h
jermar
/trunk/uspace/
Support for close().
2731
6074 d 20 h
jermar
/trunk/uspace/srv/
Add the VFS_FREE operation. This operation frees up whatever resources used by
a file system node for which there is no name (i.e. an unlinked node).
Cleanup VFS operations enums and remove unneeded VFS operations.
2730
6075 d 22 h
jermar
/trunk/uspace/srv/
Introduce the notion of VFS node link counts.
2709
6095 d 16 h
jermar
/trunk/uspace/srv/vfs/
VFS_OPEN and VFS_WRITE now understand O_APPEND.
2707
6095 d 18 h
jermar
/trunk/uspace/
Support for mkdir().
2704
6096 d 21 h
jermar
/trunk/uspace/srv/vfs/
Additional VFS lookup flags.
2700
6103 d 19 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).
2693
6109 d 20 h
jermar
/trunk/uspace/
Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.
2691
6113 d 13 h
jermar
/trunk/uspace/srv/vfs/
Improve the API for converting (VFS triplets, size) to VFS nodes by introducing
a new type for results of vfs_lookup_internal().
2690
6114 d 11 h
jermar
/trunk/uspace/srv/
Make a distinction between VFS operations that are common to VFS and FS
implementations, operations that are VFS only and operations that are FS
implementations only.
2687
6114 d 13 h
jermar
/trunk/uspace/srv/
Management of the cached VFS node size.
2684
6116 d 14 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).
2683
6116 d 16 h
jermar
/trunk/uspace/srv/vfs/
Introduce the open file lock. Modify vfs_rdwr() to take this lock into account
when reading or writing from/to an open file.
2682
6116 d 19 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
6116 d 20 h
jermar
/trunk/uspace/
Turn the namespace futex into rwlock.
2680
6116 d 20 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.
2679
6120 d 13 h
jermar
/trunk/uspace/srv/vfs/
Rename unlink_futex to namespace_futex and introduce a new futex for serializing
concurrent access to a VFS node's contents by multiple clients.
