Description Fred Riss 2004-01-12 14:45:06 UTC
[ Copy pasting from sourceforge tracker ]

 The directory selection dialog for directory diffs
could include a counter representing the recursivity of
the diff.

Currently it's very hard to diff the base of a very
deep tree because of the time scanning all the subtrees

============ Reply from steve ==============

Good idea - but I think it would be better to make the scanning
more intelligent than to specify some arbitrary limit.

How about: scan breadth first instead of depth first
Except if a user opens a directory then it is scanned
Comment 1 Fred Riss 2004-01-12 15:17:55 UTC
I think improving the scanning algorithm like you say is a good thing
and would maybe solve the problem when you do recursive diffs.
Nevertheless, I would really love to have an option to not recurse in
Comment 2 Mantas Kriaučiūnas 2004-06-16 22:47:14 UTC
Also it would be nice to have an option "Don't follow symlink", should I report
another bug ?
Comment 3 Stephen Kennedy 2004-06-17 08:08:28 UTC
Yes, please open a separate bug.
Comment 4 Björn Stenberg 2009-06-17 13:40:01 UTC
I too would like an option to disable recursive compare.

I have a tree with literally hundreds of thousands of files. I need to be able to compare a single level of this tree. Comparing the whole huge tree structure is useless, not to mention takes hours.
Comment 5 Stephen Kennedy 2009-07-11 13:14:02 UTC
If you'd like to have a look at this, see
The line containing todo.append is where the recursion is performed.
I suppose you could examine the number of "/" in the name at this point.

I'm working on a patch.
Functionality and UI is there, but I have no idea on where to save the max. recursion depth and on how to pass that the way down to _search_recursively_iter.
Comment 7 fcodvpt 2017-01-18 16:20:32 UTC
I would also really really appreciate an option to disable recursive diff for directory comparison. As proposed above, with this option enabled, a directory is scanned for diff only when it is opened.

Collapsing subfolders takes a long time when you just want to compare a known subset of the tree, and you have to do it again when you change an option (do not display identical files e.g).

See also bug 759683, bug 776828.
