I'm not sure if this is a bug or a feature but the question is should files have (some/any)
|
||||
explicit metadata set with `git-annex metadata` for them to be included in a view branch?
|
||||
I mean if you create a view with just path-based fields (say, restrict to a subdirectory
|
||||
with a criterion like 'subdir/=*'), do you expect files to match even if they don't have
|
||||
any metadata fields manually set? In release version 10.20230214 the behavior has changed
|
||||
in that files that don't have manual metadata set don't seem to be included in
|
||||
(directory-based) view branches. The inverse seems to be true of the unreleased version
|
||||
10.20230127-gc209e0f64 committed a week before.
|
||||
|
||||
In my opinion, this *could* be a feature if it's documented but it could also be construed
|
||||
as violating the principle of least surprise as not all users routinely tag all annexed files
|
||||
with metadata.
|
||||
|
||||
The following is a transcript that illustrates how the recent release version behaves. See
|
||||
how the file `subdir/c` is excluded from the view branch (my apologies for this being a
|
||||
PowerShell session on Windows):
