Hi,
I've been looking at the refspecs for git fetch, and noticed that
globs are partially supported. I wanted to use something like:
refs/tags/some-prefix-*:refs/tags/some-prefix-*
as a refspec, so that I can fetch only tags which have a specific
prefix. I know that I could use namespaces to separate tags, but
unfortunately, I am unable to fix the tag format. The specific
repository in question is also generating several tags which are not
relevant to me, in formats that are not really useful for human
consumption. I am also not able to fix this less than useful practice.
However, I noticed that refspecs only support * as a single component.
The match algorithm works perfectly fine, as documented in
abd2bde78bd9 ("Support '*' in the middle of a refspec")
What is the reason for not allowing slightly more arbitrary
expressions? Obviously no more than one *...
It seems like the "strict" requirements, as in the above commit, but i
an unable to find what these requirements are, and why they can't
allow more expressions.
It's possible that users might not expect it to work, but maybe it
could be configured behind an extra option to prevent accidental use?
I think it's quite intuitive though.
Maybe because it allows some shenanagins to rename tags, but... that's
really the user's fault... Another reason for putting this behind an
option possibly?
Personally I would like to be able to use this as it allows much more
fine grained control over what I fetch, and lets me stick with the
un-namespaced tags which are something I can't change.
If this isn't something that can be done I would appreciate a good
explanation of what it might break and why it's a bad idea...
Regards,
Jake
