| Changes to `entries' management: |
| (for post-M2) |
| |
| 1. Directories will now have flags stored in *2* places: in THIS_DIR |
| and in its parent's subdir entry. |
| |
| As a rule, a subdir entry will never contain any info other than |
| the subdir's name and its flags. |
| |
| ==> We must change all code that adds/removes flags to manage dir |
| flags in both locations. (Mainly the merge_sync routines.) |
| |
| 2. When retrieving a hash full of entries, the hash will represent |
| *exactly* whatever information is available in the entries file. |
| We will *not* traverse up or down directories in search of extra |
| information. |
| |
| In particular, the only "inferences" of information allowed are |
| listed here: |
| |
| * a file entry is assumed to inherit it's revision and URL from |
| THIS_DIR, if none is specified. |
| |
| * all file and subdir entries implicitly inherit a 'delete' |
| flag from THIS_DIR, if one is present. |
| |
| ==> Change resolve_to_defaults to stop traversing up and down, and |
| only do the specific inferences above. |
| |
| ==> Change *ALL* callers of svn_wc_entries_read, and make sure |
| they understand that they're getting a hash with missing |
| information; teach them to fetch the info they need. This is a |
| *big* change. |
| |
| 3. The command 'svn rm dir' causes all subdirs of DIR to be |
| automatically marked for deletion. (And by inference rules, all |
| files anywhere in the subtree as well.) |
| |
| 4. The command 'svn add dir' only marks the one dir for addition. |
| In the future, maybe we can add a -R recursive flag to the add |
| command, or maybe people can just use 'svn import'. |
