bug#42162: gforge.inria.fr to be taken off-line in Dec. 2020

[Ludovic Courtès]

Hello!

The hosting site gforge.inria.fr will be taken off-line in December
2020.  This GForge instance hosts source code as tarballs, Subversion
repos, and Git repos.  Users have been invited to migrate to
gitlab.inria.fr, which is Git only.  It seems that Software Heritage
hasn’t archived (yet) all of gforge.inria.fr.  Let’s keep track of the
situation in this issue.

The following packages have their source on gforge.inria.fr:

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> ,pp packages-on-gforge
$7 = (#<package r-spams@2.6-2017-03-22 gnu/packages/statistics.scm:3931 
7f632401a640>
 #<package ocaml-cudf@0.9 gnu/packages/ocaml.scm:295 7f63235eb3c0>
 #<package ocaml-dose3@5.0.1 gnu/packages/ocaml.scm:357 7f63235eb280>
 #<package mpfi@1.5.4 gnu/packages/multiprecision.scm:158 7f632ee3adc0>
 #<package pt-scotch@6.0.6 gnu/packages/maths.scm:2920 7f632d832640>
 #<package scotch@6.0.6 gnu/packages/maths.scm:2774 7f632d832780>
 #<package pt-scotch32@6.0.6 gnu/packages/maths.scm:2944 7f632d8325a0>
 #<package scotch32@6.0.6 gnu/packages/maths.scm:2873 7f632d8326e0>
 #<package gf2x@1.2 gnu/packages/algebra.scm:103 7f6323ea1280>
 #<package gmp-ecm@7.0.4 gnu/packages/algebra.scm:658 7f6323eb4960>
 #<package cmh@1.0 gnu/packages/algebra.scm:322 7f6323eb4dc0>)
--8<---------------cut here---------------end--------------->8---

‘isl’ (a dependency of GCC) has its source on gforge.inria.fr but it’s
also mirrored at gcc.gnu.org apparently.

Of these, the following are available on Software Heritage:

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> ,pp archived-source
$8 = (#<package ocaml-cudf@0.9 gnu/packages/ocaml.scm:295 7f63235eb3c0>
 #<package ocaml-dose3@5.0.1 gnu/packages/ocaml.scm:357 7f63235eb280>
 #<package pt-scotch@6.0.6 gnu/packages/maths.scm:2920 7f632d832640>
 #<package scotch@6.0.6 gnu/packages/maths.scm:2774 7f632d832780>
 #<package pt-scotch32@6.0.6 gnu/packages/maths.scm:2944 7f632d8325a0>
 #<package scotch32@6.0.6 gnu/packages/maths.scm:2873 7f632d8326e0>
 #<package isl@0.18 gnu/packages/gcc.scm:925 7f632dc82320>
 #<package isl@0.11.1 gnu/packages/gcc.scm:939 7f632dc82280>)
--8<---------------cut here---------------end--------------->8---

So we’ll be missing these:

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> ,pp (lset-difference eq? $7 $8)
$11 = (#<package r-spams@2.6-2017-03-22 gnu/packages/statistics.scm:3931 
7f632401a640>
 #<package mpfi@1.5.4 gnu/packages/multiprecision.scm:158 7f632ee3adc0>
 #<package gf2x@1.2 gnu/packages/algebra.scm:103 7f6323ea1280>
 #<package gmp-ecm@7.0.4 gnu/packages/algebra.scm:658 7f6323eb4960>
 #<package cmh@1.0 gnu/packages/algebra.scm:322 7f6323eb4dc0>)
--8<---------------cut here---------------end--------------->8---

Attached the code I used for this.

Thanks,
