opam 2.0 beta 3 update is not working correctly #2993

Closed bikallem closed 7 years ago

bikallem commented 7 years ago

I am using opam version 2.0.0~beta3. After issuing opam update I get the following text,

=-=- Updating package repositories =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
[default] no changes from https://opam.ocaml.org/2.0
[WARNING] Errors in /home/usr1/.opam/repo/default/repo, some fields have been ignored:
            - At /home/usr1/.opam/repo/default/repo:10:0:
              Invalid field stamp

[WARNING] Errors in /home/usr1/.opam/repo/default/repo, some fields have been ignored:
            - At /home/usr1/.opam/repo/default/repo:10:0:
              Invalid field stamp

Now run 'opam upgrade' to apply any package updates.

After issuing opam upgrade it asks me recompile all of my installed packages. Excerpt shown below,

....
  - recompile ppx_metaquot            v0.9.0            [upstream changes]
  - recompile ppx_let                 v0.9.0            [upstream changes]
  - recompile ppx_here                v0.9.1            [upstream changes]
  - recompile fieldslib               v0.9.0            [upstream changes]
  - recompile odig                    0.0.2             [upstream changes]
  - recompile core                    v0.9.1            [upstream changes]
===== 108 to recompile =====
Do you want to continue ? [Y/n]

The issue is that opam asks me to upgrade and then recompile every time I do opam update. This is clearly not tenable.

opam config report returns the following,

# opam config report
# opam-version    2.0.0~beta3

The first error on update is due to a just-added field, and should be harmless. The second is clearly a bug, all packages haven't been changed every time. Could you provide me with the output of opam upgrade -vvv --debug ?

Thanks !

Do you want to continue ? [Y/n]

Hmm, so opam did detect changes in all of your installed packages. This normally happens only if the hash for their sources changed, or the package definition changed in a meaningful way (e.g. build instructions, but not maintainer).

00:00.335  STATE                   Detected changed packages (marked for reinstall): { alcotest.0.7.2, asetmap.0.8.1, astring.0.8.3, base.v0.9.3, base-bytes.base, base-num.base, base64.2.2.0, bin_prot.v0.9.0, bos.0.1.6, cmdliner.1.0.0, conf-m4.1, conf-perl.1, conf-which.1, configurator.v0.9.1, core.v0.9.1, core_kernel.v0.9.0, depext.1.0.4, doc-ock.1.1.1, doc-ock-html.1.1.1, doc-ock-xml.1.1.0, fieldslib.v0.9.0, fmt.0.8.3, fpath.0.7.2, jane-street-headers.v0.9.0, jbuilder.1.0+beta10, js_of_ocaml.3.0, js_of_ocaml-compiler.3.0, jsonm.1.0.1, lambda-term.1.11, logs.0.6.2, merlin.2.5.5, mtime.1.1.0, num.0, ocaml-compiler-libs.v0.9.0, ocaml-manual.4.04.0, ocaml-migrate-parsetree.1.0.1, ocamlbuild.0.11.0, ocamlify.0.0.1, ocp-indent.1.6.0, ocp-index.1.1.5, ocp-index-top.0.4.1, octavius.1.1.0, odig.0.0.2, odoc.1.1.1, opam-core.2.0.0~beta3.1, opam-format.2.0.0~beta3.1, ppx_assert.v0.9.0, ppx_ast.v0.9.1, ppx_base.v0.9.0, ppx_bench.v0.9.1, ppx_bin_prot.v0.9.0, ppx_compare.v0.9.0, ppx_core.v0.9.0, ppx_custom_printf.v0.9.0, ppx_deriving.4.1, ppx_driver.v0.9.1, ppx_enumerate.v0.9.0, ppx_expect.v0.9.0, ppx_fail.v0.9.0, ppx_fields_conv.v0.9.0, ppx_hash.v0.9.0, ppx_here.v0.9.1, ppx_inline_test.v0.9.1, ppx_jane.v0.9.0, ppx_js_style.v0.9.0, ppx_let.v0.9.0, ppx_metaquot.v0.9.0, ppx_optcomp.v0.9.0, ppx_optional.v0.9.0, ppx_pipebang.v0.9.0, ppx_sexp_conv.v0.9.0, ppx_sexp_message.v0.9.0, ppx_sexp_value.v0.9.0, ppx_traverse.v0.9.0, ppx_traverse_builtins.v0.9.0, ppx_type_conv.v0.9.0, ppx_typerep_conv.v0.9.0, ppx_variants_conv.v0.9.0, react.1.2.1, result.1.2, rresult.0.5.0, sexplib.v0.9.1, spawn.v0.9.0, stdio.v0.9.0, topkg.0.9.0, tuareg.2.0.10, typerep.v0.9.0, uchar.0.0.1, user-setup.0.6, utop.2.0.1, uutf.1.0.1, variantslib.v0.9.0, webbrowser.0.6.1, xmlm.1.3.0, zed.1.5 }

That might be due to changes in the way the 1.2⇒2.0 repository rewrite is done (what repository do you use ?), but surely the reinstalls shoud be done only once.

You can check and manage pending reinstalls using:

opam reinstall --pending
opam reinstall --list-pending
opam reinstall --forget-pending

Indeed, these commands seem to have fixed the issue. Thanks.

opam reinstall --pending opam reinstall --list-pending opam reinstall --forget-pending Thanks.
