Super excited for this! Thank you to everyone whose put in so much hard work to get it done!

One question: what is happening with the trac tickets mailing list? I imagine it’ll be going away, but for those of us that use it to keep track of things is there a recommended alternative?

The ghc-commits list will continue to work. The ghc-tickets list is a good question. I suspect that under gitlab there will be less need for this list but we may still want to continue maintaining it regardless for continuity's sake. Thoughts? Cheers, - Ben

Hi everyone,

Over the past few weeks we have been hard at work sorting out the last batch of issues in GHC's Trac-to-GitLab import [1]. At this point I believe we have sorted out the issues which are necessary to perform the final migration:

* We are missing only two tickets (#1436 and #2074 which will require a bit of manual intervention to import due to extremely large description lengths)

* A variety of markup issues have been resolved

* More metadata is now preserved via labels. We may choose to reorganize or eliminate some of these labels in time but it's easier to remove metadata after import than it is to reintroduce it. The logic which maps Trac metadata to GitLab labels can be found here [2]

* We now generate a Wiki table of contents [3] which is significantly more readable than GitLab's default page list. This will be updated by a cron job until underlying GitLab pages list becomes more readable.

* We now generate redirects for Trac ticket and Wiki links (although this isn't visible in the staging instance)

* Milestones are now properly closed when closed in Trac

* Mapping between Trac and GitLab usernames is now a bit more robust

As in previous test imports, we would appreciate it if you could have a look over the import and let us know of any problems your encounter.

If no serious issues are identified with the staging site we plan to proceed with the migration this coming weekend. The current migration plan is to perform the final import on gitlab.haskell.org on Saturday, 9 March 2019.

This will involve both gitlab.haskell.org and ghc.haskell.org being down for likely the entirety of the day Saturday and likely some of Sunday (EST time zone). Read-only access will be available to gitlab.staging.haskell.org for ticket lookup while the import is underway.

After the import we will wait at least a week or so before we begin the process of decommissioning Trac, which will be kept in read-only mode for the duration.

Do let me know if the 9 March timing is problematic.

Cheers,

- Ben
