opam-repository compatibility with opam 1.1.1

[edwintorok]

I first thought that my .opam got corrupted and reported an opam bug: https://github.com/ocaml/opam/issues/1605. But creating a fresh .opam has the same problem: opam wants to install ocamlfind again even though it was just installed.

$ rm -rf ~/.opam
$ opam --version
1.1.1
$ opam init
[...]
$ opam install lwt
The following actions will be performed:
 - install base-threads.base [required by lwt]
 - install ocamlfind.1.5.2 [required by lwt]
 - install base-unix.base [required by lwt]
 - install camlp4.4.01.0 [required by lwt]
 - install lwt.2.4.5
[..]

$ opam list
Installed packages for system:
base-bigarray    base  Bigarray library distributed with the OCaml compiler
base-threads     base  Threads library distributed with the OCaml compiler
base-unix        base  Unix library distributed with the OCaml compiler
camlp4         4.01.0  Camlp4 is a system for writing extensible parsers for programming languages
lwt             2.4.5  A cooperative threads library for OCaml
ocamlfind       1.5.2  A library manager for OCaml

The beta version doesn't have this problem (opam_1.1.99+SNAPSHOT20140813-1ppa2~stable_amd64.deb), but I think the repository should be kept compatible with the stable version too ...

really weird... never had an issue like that before, and I can't see how the repo would be in cause ; OPAM debug output does correctly contain:

Could you try with --cudf <file> and join the generated <file>-1.cudf ?

Thanks !

(didn't manage to reproduce on debian testing using this version)

I was able to install Lwt and utop previously with opam from Debian, in fact they were both installed but then something broke. Besides 'opam update' is there anything else that might've changed in Debian unstable to cause this?

OPAM debug output does correctly contain:

00:00.045 018228 STATE INSTALLED : { base-bigarray.base, base-threads.base, base-unix.base, camlp4.4.01.0, lwt.2.4.5, ocamlfind.1.5.2 } 00:00.045 018228 STATE ROOTS : { base-bigarray.base, base-threads.base, base-unix.base, lwt.2.4.5 }

Could you try with |--cudf | and join the generated |-1.cudf| ?

Attached.

Apparently the comment got truncated, here is a gist:

https://gist.githubusercontent.com/edwintorok/bbf5eaaacdcd07387af3/raw/8c1195865d0e6e297fe8a5997a739f51ca25d89b/file-1.cudf

I just tested with an older opam repository an opam 1.1.1 with ocamlfind.1.4.1, and even there it installed ocamlfind twice, except it probably went unnoticed because the duplicate install worked.

It looks like this got broken by adding ocamlfind.1.5.1 to the repository, which introduced the 'bytes' package, so running 'make install' on ocamlfind twice started to fail now, because the package already existed.

The question is why would opam 1.1.1 install ocamlfind again (without at least uninstalling the old one first), when running 'opam list' and 'opam install ocamlfind' both say that it is already installed.

I thought I would bisect to find out where this got fixed, but checking out and building 1.1.1 from the upstream git repo works, it is only 1.1.1 from Debian thats broken. There aren't any signifcant patches on the Debian side, except its built differently: it uses the system versions of dose3/cudf/etc., instead of the embedded ones.

If I check-out the upstream repository for opam 1.1.1 and use the Debian buildsystem I can confirm that its broken (using the upstream buildsystem works), so it probably has to do something with the version of those external libraries, more investigation is needed to figure out which library got broken ...

[edwintorok]

Looks like it is the dose.3.1.2 -> dose.3.2.2 transition that broke both opam 1.1.1 and opam 1.1.2. The beta version of opam 1.2.0 works with dose.3.2.2 though. At the time opam was added to the Debian repo initially dose was still at 3.1.2, but then it got upgraded, opam rebuilt (hence the +B1 in the version: 1.1.1-1+b1), and now opam is broken in Debian. Anyway, not a bug in the repository, so closing this bug.
