|
* This file is part of the CernVM File System |
| 3 |
|
|
* |
| 4 |
|
|
* This tool figures out the changes made to a cvmfs repository by means |
| 5 |
|
|
* of a union file system mounted on top of a cvmfs volume. |
| 6 |
|
|
* We take all three volumes (namely union, overlay and repository) into |
| 7 |
|
|
* account to sync the changes back into the repository. |
| 8 |
|
|
* |
| 9 |
|
|
* On the repository side we have a catalogs directory that mimics the |
| 10 |
|
|
* shadow directory structure and stores compressed and uncompressed |
| 11 |
|
|
* versions of all catalogs. The raw data are stored in the data |
| 12 |
|
|
* subdirectory in zlib-compressed form. They are named with their SHA-1 |
| 13 |
|
|
* hash of the compressed file (like in CVMFS client cache, but with a |
| 14 |
|
|
* 2-level cache hierarchy). Symlinks from the catalog directory to the |
| 15 |
|
|
* data directory form the connection. If necessary, add a .htaccess file |
| 16 |
|
|
* to allow Apache to follow the symlinks. |
