Bug#886096: lintian: Emit warnings for Alioth URLs in packaging (migration to Salsa)

[Niels Thykier <niels@thykier.net>]

Axel Beckert:
> Package: lintian
> Version: 2.5.67
> Severity: wishlist
> 
> According to https://wiki.debian.org/Salsa/Doc all packaging projects
> hosted on Alioth need to be moved away, preferably to Salsa.
> 
> This at least affects:
> 
> * ${VCS}.debian.org and anonscm.debian.org in Vcs-* headers and
>   debian/upstream/metadata (with ${VCS} in at least git, svn, hg, bzr,
>   darcs, arch, and cvs).
> 
> * http(s)://*.alioth.debian.org/ in Homepage headers,
>   debian/upstream/metadata, and maybe also debian/copyright.
> 
> IMHO these should emit a tag at at least warning/normal level.
> 
> According to https://wiki.debian.org/Alioth/MailingListContinuation the
> urgency for changing Maintainer fields, etc. which point to Alioth
> mailing lists is lower. Hence for now, I suggest to also emit a
> (separate) tag for these, but with severity informational/minor:
> 
> * lists.alioth.debian.org in the Maintainer and Uploaders fields
> 
> * Maybe also lists.alioth.debian.org elsewhere in packaging,
>   e.g. Mailing list archives in debian/upstream/metadata,
>   debian/copyright or so.
> 
> Additionally, some currently emitted tags can be probably removed or
> replaced with according salsa.debian.org-based tags:
> 
> * vcs-field-not-canoncial
> 
> Then there's another set which might need updates, too:
> 
> * vcs-field-bitrotted
> * vcs-field-uses-not-recommended-uri-format
> * vcs-git-uses-invalid-user-uri
> 
> Feel free to clone this bug report in case these things won't be
> implemented at the same time.

My 2 cents: I do not think we should propose a mass-move until salsa is
out of the beta.  Given that the admins have not commited to not wiping
the database, nagging people to move seems counter productive
(especially if a wipe is performed later).
