To-do items from 1.50-PR2

[adrianlopezroche]

Old to-do list from fdupes 1.50-PR2. I'm removing the TODO file from the master branch, so I've copied the contents here. A few of these have already been implemented, others not. This list is only for reference and is not meant to preclude or discourage adding any of these issues to the issue tracker.

• A bug with -S shows wrong results.

• A bug causes the following behavior:

  $ fdupes --symlinks testdir testdir/with spaces b testdir/with spaces a

  testdir/zero_b testdir/zero_a

  testdir/symlink_two testdir/twice_one

  $ cp testdir/two testdir/two_again $ fdupes --symlinks testdir testdir/two_again testdir/two testdir/twice_one testdir/symlink_two

  testdir/with spaces b testdir/with spaces a

  testdir/zero_b testdir/zero_a

  ** This is not the desired behavior. Likewise:

  $ fdupes testdir testdir/with spaces b testdir/with spaces a

  testdir/zero_b testdir/zero_a

  testdir/twice_one testdir/two

  $ fdupes --symlinks testdir testdir/with spaces b testdir/with spaces a

  testdir/zero_b testdir/zero_a

  testdir/symlink_two testdir/twice_one

• Don't assume that stat always works.

• Add partial checksumming where instead of MD5ing whole files we MD5 and compare every so many bytes, caching these partial results for subsequent comparisons.

• Option -R should not have to be separated from the rest, such that "fdupes -dR testdir", "fdupes -d -R testdir", "fdupes -Rd testdir", etc., all yield the same results.

• Add option to highlight or identify symlinked files (suggest using --classify to identify symlinks with @ suffix... when specified, files containing @ are listed using @).

• Consider autodeletion option without user intervention.

• Consider option to match only to files in specific directory.

• Do a little commenting, to avoid rolling eyes and/or snickering.

• Fix problem where MD5 collisions will result in one of the files not being registered (causing it to be ignored).
