/trunk/uspace/srv/fs/tmpfs/ |
Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup. |
|

/trunk/uspace/ |
More elegant, flexible and complete version of tmpfs_lookup. |
|

Additional VFS lookup flags. |

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). |

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. |

/trunk/uspace/srv/vfs/ |
Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules. |
|

/trunk/uspace/lib/libc/ |
Add opendir(), rewinddir(), closedir() and some prototypes and stubs. Add dirent.h. |
|
| 2693 |
6004 d 1 h |

/trunk/uspace/ |
Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS. |
|
| 2691 |
6007 d 18 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(). |
|

6008 d 16 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. |

/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. |

/trunk/uspace/srv/fs/tmpfs/ |
Previous commit was toxic. When emulating gaps, zero out the reallocated buffer, not the original one. |
|

6008 d 18 h |

/trunk/uspace/srv/fs/tmpfs/ |
TMPFS must handle file gaps. |
|
| 2684 |
6010 d 18 h |

/trunk/ |
Add libc and VFS implementation of lseek(), VFS_SEEK resp.
Add the size member to the VFS node structure (not yet initialized). |
|
| 2683 |
6010 d 21 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 |
6011 d 0 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 |
6011 d 1 h |
jermar |
/trunk/uspace/ |
Turn the namespace futex into rwlock. |
|
| 2680 |
6011 d 1 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. |
