Re: Is label support in future release?

I don't know that the effort of creating a label would be any less...
but some common manipulations might be.

1) moving a label means removing the old and recreating it - no need
for history since a label is a point in history. Moving a tag is a
delete and a recopy which does turn up in history.

2) listing logs between two labels (since they're revision aliases) is
trivial. Doing the same from tags is non-trivial requiring two logs
with stop on copy to get the revisions in question.

Perhaps if we were to list all of the expected uses of labels, then
for each use discuss what the existing facilities provide for in the
way of solutions. We then need to postulate as to how labels would
either better facilitate these processes and perhaps what
functionality labels might give beyond what is practical using
existing facilities.

I expect such a formal approach will be the only means by which you
convince existing developers (or draw in new developers) to add this
feature.

I'll start with the obvious simple case.

1. Labels provide a contextual and memorable alias for a revision number.

A tag can do this as well. You create the tag and then when you need
the revision number it refers to you must execute a log 'stop on copy'
command on the tag URL.

A label on the other-hand is an explicit alias for a revision number
and could be used directly.

svn label -rN pre_import_checkpoint
...
svn log -rpre_import_checkpoint:HEAD ...
