Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules. |
|
| 2693 |
5966 d 23 h |
jermar |
/trunk/uspace/ |
Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS. |
|
| 2691 |
5970 d 17 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 |
5971 d 15 h |

/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. |
|
| 2689 |
5971 d 16 h |
jermar |
/trunk/uspace/srv/vfs/ |
Merge all VFS operations into one file. |
|

/trunk/uspace/ |
Make uspace rwlock API naming conventions consistent with kernel rwlock API. |
|
| 2687 |

/trunk/uspace/srv/ |
Management of the cached VFS node size. |
|
| 2684 |
5973 d 17 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 |
5973 d 20 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 |
5973 d 22 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 |
5973 d 23 h |

/trunk/uspace/ |
Turn the namespace futex into rwlock. |
|
| 2680 |
5974 d 0 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. |

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 |
5979 d 20 h |

/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. |

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. |
|

5985 d 16 h |

VFS and TMPFS support for VFS_WRITE. |
|
| 2663 |
5987 d 15 h |
jermar |
/trunk/uspace/ |
Reimplement VFS_READ using IPC_M_DATA_READ. |
|
| 2660 |
5987 d 17 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(). |

After VFS_READ, update the position pointer in the open file. |
