| This experimental branch is intended to explore the idea of introducing a |
| svn_fs_node_t abstraction in the FS API. |
| |
| The branch should be maintained with catch-up merges from trunk. |
| |
| The branch is NOT going to be merged to trunk; I'm going to re-implement |
| everything in trunk in case we find the svn_fs_node_t API useful. |
| |
| STATUS |
| ====== |
| - Define svn_fs_node_t abstraction |
| - Implement compatibility shim implementation for svn_node_t |
| - Switch libsvn_repos code to the new API |
| - Natively implement svn_fs_node_t in FSFS |
| |
| PROBLEM |
| ======= |
| Currently, all FS API functions accept an svn_fs_root_t and a PATH as their |
| arguments. In order to find the actual node and to retrieve the requested |
| information from these arguments, the FS implementation has to perform a |
| DAG walk. |
| |
| PROPOSED SOLUTION |
| ================= |
| The idea is to introduce a svn_fs_node_t abstraction and use it in FS API |
| to access certain information about the nodes. Relevant FS functions will |
| be revved and will start returning svn_fs_node_t instances instead of node |
| paths. This should help to avoid DAG walks. |
