dim-0.5.5-pb3
Fixed a bug in update_sum() for symlinks.
To find regular file changes, we use the following expression:
find versiondir -type f '(' -cnewer scanfile -o -links 1 ')'
The empty file scanfile stores the time of the last scan.
The version directory is maintained by 'dim add|del'.
Files in the version directory are hard linked to the
corresponding file in the clone directory. After the user
changes the contents of a file in the clone, either
1. the hard link is preserved, and the change is detected by
-cnewer scanfile
2. or the hard link is broken, and the change is detected by
-links 1
For symlinks, we cannot use the hard link trick, because
hardlinking symlinks is not portable. We have to use an
absolute scan each time:
find versiondir -type l
Work in progress - Do not use this version!
