No it's /not/ the end of the story. The essential part of the
story is
how Monticello remains compatible and interoperable between
dialects. I
haven't seen you account for how you maintain that
compatibility. As
far as I can tell, you propose replacing the Monticello metadata
with
that from git. How do I, as a Squeak user with Monticello, ever
get to
look at your package again? As I understand it, moving the
metadata
from Monticello commit time to git means that the metadata is
in a
format that git determines, not Monticello.
Yes. See below why.
So I don't understand how on the one hand you can say "The
Monticello
metadata in a git repository is redundant and leads to
unnecessary
commit conflicts -- end of story ....", which implies you
want to
eliminate the Monticello metadata, and on the other hand you say
you're
keeping the Monticello metadata. I'm hopelessly confused. How
does the
Monticello metadata get reconstituted if it's been thrown away?
What happens to the metadata in the following workflow?
load package P from Monticello repository R into an image
change P, commit via git to local git repository G
load P from G into an image
store P to R via Monticello
It's not a scenario I've specifically worked on, but all the tech is
implemented / implementable to do that perfectly.
The only thing that is problematic there is that the only safe
history is the one generated from git... there are so many MC
packages with broken history that, on mcz packages, you have to
admit that it's not safe to base things on their history.
I'm sorry but I don't accept that. In the Squeak trunk we have history
in our mczs that is correct. Certainly in VMMaker.oscog I have history
that goes back a long time. If bugs have broken history then efforts
should be made to repair that history. But you can't just write off
Monticello history like that.
I don't. You presuppose.
I write tools that work with Monticello repositories, not just yours.
I have to do with what is given to me. On a general level, as a mcz
user, I'll just have to consider that you are as susceptible to be
trusted as with any other mcz producer. This means not much...
... And this is the reason why I am inclined to favor option 3, which
records the package version history as it existed at the point it was
copied into a git repo. When copied back out from the git universe,
create a version history that starts with the original version history
and generates a history of the package in git ....
Correct or not, the Monticello version history should be preserved ....
