Antw: Re: Q: "git diff" using tag names

Hello Alexey,

thank you very much for your reply. I felt I did something wrong, but couldn't find out what it was. Actually it turned out that I had just mistyped one tag name.

Also it seems that both syntaxes work:
git diff v0.4..v0.5
git diff v0.4 v0.5

The question is: How does git disambiguate between tag names, commits and file names? (All may start with a letter)
This seems to work automagically, and I was desparately looking for an option like "--" to separate revisions from file names. I found "SPECIFYING REVISIONS" in git-rev-parse(1), so you don't really have to answer.

Regards,
Ulrich

Nachricht [ref]:

Tag is a pointer to a commit (if to say simply)

e.g. in my repo
$ git show-ref --tags --abbrev=7
-->8--
676f194 refs/tags/v2.6.7
b23c481 refs/tags/v2.6.8
-->8--

so

$ git diff v2.6.7..v2.6.8
is equivalent to
$ git diff 676f194..b23c481

etc

Hi,

when using a somewhat older git (of SLES11 SP1 SDK), I could not find
a way to "git diff" between two tag names; I can only diff between
two commit numbers. I can display a changeset using "git show", but
that's not what I wanted. Is it possible to get the diff I want using
older versions, and is such a feature implemented in the current
version? If so, since when?

As I'm not subscribed to the list, I'd appreciate CC'ed replies.
Thank you.

Greeting
Ulrich
