However, as discussed at [2], planning the migration of the repository is quite a delicate matter ; this doesn't have to be done at the same time as the release itself, but some confusion may arise if we advertise a new workflow that leads to packages that get refused from the main repo because they're not 1.1 compatible.</div><div style="margin: 0px; text-indent: 0px;">> > </div><div style="margin: 0px; text-indent: 0px;">> > We tried to improve compatibility for the next release, but for 1.2 there are just too many changes and opam 1.1 _won't_ nicely handle them. So here is how I have been preparing:</div><div style="margin: 0px; text-indent: 0px;">> > </div><div style="margin: 0px; text-indent: 0px;">> > - a batch conversion of the existing repo [7]: not required but useful for 1.2 (adding dev repos for archives held on github, setting ocamlfind deps as build-only, turning depopts constraints to conflicts [3]...). This is useful as a starting point for repo extension and example, and done using scripts in `admin-scripts/` [4]</div><div style="margin: 0px; text-indent: 0px;">> > </div><div style="margin: 0px; text-indent: 0px;">> > - a `admin-scripts/to_1_1.ml` script in opam [5] that can convert a package back to 1.1 format. I successfully tested it on the above repo and with opam 1.1 ; there may be corner cases on new 1.2 opam files that this didn't get into, but these can be caught by Travis before they break.</div><div style="margin: 0px; text-indent: 0px;">> > </div><div style="margin: 0px; text-indent: 0px;">> > - updated admin scripts on the 11-bridge branch of <a href="http://opam.ocaml.org">opam.ocaml.org</a> [6]. The new scripts create a duplicate of the repo at <a href="http://opam.ocaml.org/1.1/">opam.ocaml.org/1.1/</a>, branch version-triggered redirects between the two, and apply the above script to the 1.1 repo mirror at every update. This should make it transparent whichever opam version is used.</div><div style="margin: 0px; text-indent: 0px;">> > </div><div style="margin: 0px; text-indent: 0px;">> > - tested the <a href="http://opam.ocaml.org">opam.ocaml.org</a> scripts on a local mirror I set up, and they seem to work fine (after _a lot_ of tweaking) ; note that these can be pushed live beforehand, they'll set up the redirects but the translation script doesn't change opam files with `opam-version` < "1.2" so it won't cause any user-visible changes until we actually accept 1.2 opam files in the repo (except for the "permanently redirected" message)</div><div style="margin: 0px; text-indent: 0px;">> > </div><div style="margin: 0px; text-indent: 0px;">> > What remains to do:</div><div style="margin: 0px; text-indent: 0px;">> > </div><div style="margin: 0px; text-indent: 0px;">> > - setup the opam-repository travis scripts to apply the 1.1 rewrite before testing, for opam versions < 1.2. Only tricky part is to get hold of a recent enough opam-lib to run the script (maybe we could cheat and put a standalone bytecode exe on opam-repository for that ; well one for 4.01 and one for 4.02 since the format changed...). This way PRs to opam-repo containing 1.2 opam files will be correctly tested, as well as the rewrite.</div><div style="margin: 0px; text-indent: 0px;">> > </div><div style="margin: 0px; text-indent: 0px;">> > - release !</div><div style="margin: 0px; text-indent: 0px;">> > </div><div style="margin: 0px; text-indent: 0px;">> > </div><div style="margin: 0px; text-indent: 0px;">> > Finally, note that I'll be moving across the globe next week, and won't be available for two weeks or so.
