as reported in ocaml/opam-repository#25690 (comment), 3.15.1 breaks ocaml-protoc-plugin.

The offending set of changes seems to be #10432 / #10382. I reverted that change in the 3.15 branch and the cycle disappeared.

• I haven't been able to finish testing out the changes between Dune 3.12.1 and 3.15.0 because of an unrelated block in the latest opam beta. If possible, would be nice if I can finish my DkML distribution testing before 3.15.1 goes out the door; it has a bunch of tests that Dune and Opam CI will not cover. I don't anticipate the opam beta blocker taking more than a day or two to resolve. I'll comment here when it is done, or just ping me.

So there's indeed a regression on ocaml-protoc-plugin, including the last version. It looks like we were ignoring the cycle before, and now it's causing an issue. I filed #10447 for this but it any case that can't be fixed in a patch release so I'll cut 3.15.2 without it.

@jonahbeckford 3.15.1 has already been tagged, but your input is valuable for 3.15.2 which I'll prepare today. Let me know if you have any feedback about it.

(amending what I said above, the fix will be to backport #10442)

[Leonidas-from-XIV]

However, given 3.15.1 is not merged, I think we should close that PR and replace it with 3.15.2.

[emillon]

yes, I'll do that when the changelog etc have been merged

[jonahbeckford]

Thanks. I have long test cycles so I'm stuck testing Dune 3.15.0 for the time being. And since I haven't found any Windows blockers (yet) I'll probably ship DkML 2.1.1 with Dune 3.15.0.

I don't have the resources to increase the cadence, so (in hindsight) it is better just keeping with the status quo.

[emillon]

OK, thanks. Note that 3.15.1 includes a fix for gcc 4.8.5.
