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. |

Previous commit was toxic. When emulating gaps, zero out the reallocated buffer, not the original one. |

TMPFS must handle file gaps. |

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

Introduce the open file lock. Modify vfs_rdwr() to take this lock into account
when reading or writing from/to an open file. |
|

/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. |
|

Turn the namespace futex into rwlock. |

/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. |
|

/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. |
|

/trunk/uspace/lib/libc/generic/ |
Actually use the nbyte argument in both read() and write().
Fix warnings in read() and write(). |
|
2674 |
6072 d 2 h |
jermar |
/trunk/uspace/ |
Add libc VFS wrapper for VFS_WRITE. Fix a small bug in read(). Place open(),
read() and write() declarations in their respective headers according to SUSv3. |
|

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

/trunk/uspace/app/tester/vfs/ |
Use libc's VFS wrappers instead of direct communication with VFS. |
|
2671 |
6072 d 3 h |
jermar |
/trunk/uspace/lib/libc/ |
Add VFS wrappers for VFS_MOUNT, VFS_OPEN and VFS_READ to libc. |

Move the open(), read() and write() provided by streams.c away so that
these functions won't clash with the real open(), read() and write(), which are
soon to be provided by a libvfs library. Applications can now use open_stdin(),
open_stdout(), read_stdin() and write_stdout(). Later, there might be an option
of providing a custom console file system, which will work similarly to how
streams' open(), read() and write() worked. |
