[Xenomai-core] Misleading git tags

[Xenomai-core] Misleading git tags

[Wolfgang Denk]

Dear Gilles,

I noticed that "git describe" does not provide helpful information for
the Xenomai repository.

For the current code (tagged as v2.5.4) I still get:

	-> git describe
	v2.5.1-349-gf8fa381

Only with the "--tags" option I get the expected result:

	-> git describe --tags
	v2.5.4

The behaviour changes from version to version:

	-> git describe v2.5.0
	fatal: No annotated tags can describe 'fddf7831dc53cce70b7196314cbd0b3aec028350'.
	However, there were unannotated tags: try --tags.
	-> git describe v2.5.1
	v2.5.1
	-> git describe v2.5.2
	v2.5.1-142-g6b3e8f2
	-> git describe v2.5.3
	v2.5.1-232-g55bf2d3
	-> git describe v2.5.4
	v2.5.1-349-gf8fa381


My recommendation is to always annotate release tags to avoid such
confusion.  Thanks.

Best regards,

Wolfgang Denk

Ok. I annotated 2.5.1 and asked Philippe about it, he told me that he
never annotated 2.4 releases, so I stopped annotating them. In fact
annotating 2.5.1 was the real mistake, but I guess you are right, I
should annotate all of them. Can we change the annotation afterwards?

Anyway, thanks for the remark. If you wonder why I pushed 2.5.4 and did
not announced it, the announce will come tonight.

Actually the 2.4 branch is annotated, except for the two last releases.

2.4 was automatically annotated in the process of migrating from svn to
git.

Not without changing the whole history, which you really don't want
to do.

I did not wonder, I just happened to notice it :-)
