Script to migrate all mcz packages to git?
Hi, I think I have seen something but can't find it right now. I would like to move to git but preserve the history (and my commit messages and the commit date/time). Is there a script that goes through all versions of a package and copies them to git repository? Will it be able to preserve the original commit date? thank you holger
There is this script from Peter Uhnak https://www.peteruhnak.com/blog/2016/03/02/moving-project-from-smalltalkhub-... but it will not be able to preserve commit date. Preserving commit dates... I think it could only be possible in metadata-ful git repositories, which I would not recommend. On Tue, Aug 2, 2016 at 12:10 PM, Holger Freyther <holger@freyther.de> wrote:

At the time of the (post) writing it did preserve commit dates, but there was no metadata-less yet. In any case, I don't see a reason why it shouldn't preserve commit dates with metadata-less â it goes mcz by mcz and recommits it with given date, no? Peter

No it doesn't set the commit date. I'm not even sure git would allow you to set commit dates in the past, but I may be wrong (this is probably what git-cvs does). I'd say that the procedure is to make a copy on a metadata-full repository, to preserve all versions (for archeology), and then now or later switch the repository to metadata-less mode. GitFileTree has an api for carrying over a committer name in a mcz to an author name into git, by preloading a map of mcz author -> git author. Thierry

git doesn't prohibit modification of history in any way, so you can do whatever you want. In fact this is how gitfiletree DID behave when I was moving last year, but I don't know whether this particular change was removed, or never integrated (i.e. just my local change). I did make mention of date when I was moving to Git http://forum.world.st/moving-to-git-and-preserving-monticello-history-td4806... Peter

Yes, Peter is right, it can be done. I intend to build a migration into the next version of Iceberg, I will pay attention on keeping date/authors.

I have modified >>#basicStoreVersion: to pass the --date option to git and now date/time is preserved. I am copying multiple related packages into the same git repository and would like to "interleave" (based on date) the different packages. In your script you first have: filesSorted := fileBlocks asSortedCollection: sortBlock. files := (filesSorted collect: [ :x | x first ]) asArray. to select which files to actually copy (as Gofer allResolved has a lot more). but after the: goSource fetch. "downloads all mcz on your computer" I would like to mix the different packages based on their date. Would you know which Gofer(?) API I can use to get a version info (?) so I can access the date? holger
Holger, It looks like Frank Shearar tackled this problem a while ago[1]. His solution is based on using gitocello[2], but it could possibly be adapted for GitFileTree ... Thierry would be able to tell ... Dale [1] http://www.lshift.net/blog/2012/08/20/monticello-git/ [2] https://github.com/timfel/gitocello On 08/02/2016 03:10 AM, Holger Freyther wrote:
