I'm currently running tests with a bunch of different tools, to see
which looks best. Right now, it looks like cvs2git is best when we
want the keywords included. And yes, I'll definitely post the exact
options as soon as I've finished the testruns.

What's the tool that is being used now?  Can you keep us up to date on
the options etc. you plan to use?

There are/were some games being played with the key words, so this
effect sounds plausible to me.

Well, we are planning to remove these tags in git anyway, and I don't
think anyone cares about those tags not being consistent.

To clarify with what Bruce said on IM to me, the situation is when the
workflow is to manually copy a file from one repo to another before
committing (a working one vs the committer one for example), it may
not be up to date on the version id. Personally this never happens
because I move files by making "cvs diff" in one and applying in the
other, not copying the files.

For one thing, this showed up in a lot of .po files for 8.1.0RC1.
Peter, can you comment on if this coincides with the tools you use to
do those things?


> so it is possible, and can be ignored.

Yeah, but do we want to? It means a git checkout of the branch tip
will be slightly different - in keywords only - from the previous
checkout in cvs.

I have reproduced this by modifying just the CVS tag:

$PostgreSQL: pgsql/src/backend/catalog/README,v 1.15 2010/07/20
18:38:53 momjian Exp $

so it is possible, and can be ignored.

Hmmm...  I quick check of CVS documentation indicates that 1.1.1 is
reserved for the "vendor branch" created by an import.  New vendor
versions can be imported and will bump 1.1.1.1 to 1.1.1.2 and so on.
 When you commit a modification to a vendor branch file, it goes
onto the trunk.  So, either there was something which *looked* like
a modification to CVS which got massaged out (whitespace or some
such), or someone independently imported the file and someone
(possibly a different someone) committed the file independently of
the import.  I think the latter is probably more likely, but the
former seems within the realm of possibility.
 
Where they are identical, unless the imported version is included in
any tag or PostgreSQL branch, I would eliminate it and keep the
"normal" copy.  Short of maintaining a coherent history, I don't see
the point of keeping two separate but identical revisions of a file.

Yeah, something like that. But why do we for the file above have one
"initial revision" and one "vendor branch", whereas for other files we
don't? (and there's no difference betweenthem)

Or rather, we do have two for example for md.c - but the second one is
not listed as being on vendor branch.

I believe revision 1.1.1.1 is normally seen only for file brought in
through the "cvs import" command.  "vendor branch" would make some
sense as a commit message for an import.
