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. |

Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules. |
|
| 2693 |
6024 d 19 h |

/trunk/uspace/ |
Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS. |
|

/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(). |
|

/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 |
6029 d 11 h |
jermar |
/trunk/uspace/srv/vfs/ |
Merge all VFS operations into one file. |

Make uspace rwlock API naming conventions consistent with kernel rwlock API. |

Management of the cached VFS node size. |

/trunk/uspace/srv/fs/tmpfs/ |
Previous commit was toxic. When emulating gaps, zero out the reallocated buffer, not the original one. |
|
| 2685 |
6029 d 12 h |
jermar |
/trunk/uspace/srv/fs/tmpfs/ |
TMPFS must handle file gaps. |
|
| 2684 |

/trunk/ |
Add libc and VFS implementation of lseek(), VFS_SEEK resp.
Add the size member to the VFS node structure (not yet initialized). |
|
| 2683 |
6031 d 15 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 |
6031 d 18 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 |
6031 d 19 h |
jermar |
/trunk/uspace/ |
Turn the namespace futex into rwlock. |
|
| 2680 |
6031 d 19 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. |
|

/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. |
|
| 2678 |

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 |
6037 d 15 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 |
6037 d 22 h |

/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. |
|
| 2673 |
6038 d 11 h |

/trunk/uspace/srv/fs/tmpfs/ |
Rename variable from 'size' to 'len'. |

The previous commit was not entirely sane.
Handle VFS_WRITE correctly when the file doesn't grow.
Handle it correctly also when the file grows. |
|

VFS and TMPFS support for VFS_WRITE. |

/trunk/uspace/srv/fs/tmpfs/ |
Fix two bugs in TMPFS-side VFS_READ. |
|
| 2663 |
6045 d 10 h |
jermar |
/trunk/uspace/ |
Reimplement VFS_READ using IPC_M_DATA_READ. |
|
| 2660 |
6045 d 12 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(). |

Start TMPFS.
Not loaded during boot as there is a reproducible kernel panic which occurs when
both tmpfs and fat are loaded. |

Move incomplete fs interface from fat.h to libfs. |

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. |
