/trunk/uspace/srv/vfs/ |
VFS_OPEN and VFS_WRITE now understand O_APPEND. |
|
| 2707 |
6122 d 9 h |

/trunk/uspace/ |
Support for mkdir(). |

Additional VFS lookup flags. |
|

6130 d 10 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). |

Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS. |
|
| 2691 |
6140 d 4 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(). |
|

6141 d 2 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. |

/trunk/uspace/srv/ |
Management of the cached VFS node size. |
|
| 2684 |
6143 d 4 h |

/trunk/ |
Add libc and VFS implementation of lseek(), VFS_SEEK resp.
Add the size member to the VFS node structure (not yet initialized). |
|

6143 d 7 h |

/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 |
6143 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 |
6143 d 10 h |

/trunk/uspace/ |
Turn the namespace futex into rwlock. |
|
| 2680 |
6143 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. |

Rename unlink_futex to namespace_futex and introduce a new futex for serializing
concurrent access to a VFS node's contents by multiple clients. |
|
| 2666 |
6155 d 4 h |

/trunk/uspace/srv/ |
VFS and TMPFS support for VFS_WRITE. |

VFS work.
During VFS_REGISTER, use strncmp() instead of strcmp().
Add one excessive convenience byte to vfs_info.name to support the
above-mentioned change. In case the fs name spans all available
characters, make sure this convenience byte is zero. |

VFS work.
Proto implementation of VFS_READ. |
|

VFS work.
Implement VFS node hash table management. |
|

6206 d 4 h |
jermar |
/trunk/uspace/srv/vfs/ |
A lot of more VFS prototyping.
VFS_OPEN gets reasonably complete, fix a limitation that prevented file
structures from being shared by multiple file descriptors, add functions for
file descriptor management, introduce unlink_futex and two new VFS operations
VFS_UNLINK and VFS_RENAME. |

VFS work.
Start implementing VFS side of VFS_OPEN.
Add vfs_node.c to contain VFS node related internal functions. |
