I used tags for ZODB until I gave in to complaints about that, and
switched to using revision numbers. The real complaint about using a
tagged external is that when the tag changes, SVN isn't smart enough
to do an incremental update. Instead, when you update after an
external tag changes:
[Andreas]
What do you mean with when the tag changes?
Not what I said: I said [when] an /external/ tag changes. I mean
when you change an external tag _in_ project A _referencing_ the
external tagged project B. Here A=Zope and B=ZODB, and the external
tags in question are the ones referencing ZODB from within the
svn:externals properties of various Zope directories.
I am still not completely sure about the problem. Yesterday I created a
tag for for ZODB 3.6.2 as ../ZODB/tags/3.6.2 and I updated the
svn:externals
for the ZODB on the Zope 2.9 branch to this new tag. When releasing 2.9.4
2.9.4 will be tagged as Zope/tags/2.9.4so what will be the problem...
both tags should never be touched...am I missing a particular usecase?
Tim is talking about the effect on an existing sandbox when the
developer (or somebody else) changes the 'svn:external'. He alleges (I
have no reason to doubt him, but haven't observed it myself) that
changing from one tag to another (e.g., from $ZSVN/ZODB/tags/3.6.3 to
$ZSVN/ZODB/tags/3.6.4) is more disruptive to those sandboxes than
shifting the revision number, but keeping the branch the same.
I think for *development* purposes that we can afford to leave the
externals pointing at branch+revision; however, for making releases, I
think we need to manage the external dependencies such that we trigger
at least the internal checkpoint release of externals.
I *really* wish that there SVN supported something like 'svn ln -r 12345
$ZSVN/foobar/branches/3.5 $ZSVN/foobar/tags/3.5.6' (such that the link
that got created was equivalent to branch + revision.
