Bug#964550: clang-10: Version handling/naming for RC releases

[Sedat Dilek]

Package: clang-10
Version: 1:10.0.1~+rc3-1
Severity: wishlist

Dear Maintainer,

as reported in LLVM bug #38998 "llvm-toolchain: Include Debian version string like for gcc"
the version handling (naming) looks uncommon to me.

In comment #23 I listed all "rc" packages I have installed on my Debian/testing (sid) AMD64 system:

root# dpkg -l | grep 'rc[0-9]' | grep -v dileks | awk '/^ii/ {print $1 " " $2 " " $3}' | column -t

ii  asciidoc-base               9.0.0~rc2-1
ii  asciidoc-common             9.0.0~rc2-1
ii  clang-10                    1:10.0.1~+rc3-1
ii  libclang-common-10-dev      1:10.0.1~+rc3-1
ii  libclang-cpp10              1:10.0.1~+rc3-1
ii  libclang1-10                1:10.0.1~+rc3-1
ii  libllvm10:amd64             1:10.0.1~+rc3-1
ii  libpython3.8:amd64          3.8.4~rc1-1
ii  libpython3.8-minimal:amd64  3.8.4~rc1-1
ii  libpython3.8-stdlib:amd64   3.8.4~rc1-1
ii  libspeex1:amd64             1.2~rc1.2-1.1
ii  libspeexdsp1:amd64          1.2~rc1.2-1.1
ii  lld-10                      1:10.0.1~+rc3-1
ii  llvm-10                     1:10.0.1~+rc3-1
ii  llvm-10-runtime             1:10.0.1~+rc3-1
ii  lua-socket:amd64            3.0~rc1+git+ac3201d-4
ii  python3.8                   3.8.4~rc1-1
ii  python3.8-minimal           3.8.4~rc1-1

So it looks like "common sense" to have "upstream-version" plus "~rcX" followed by "-debian-revision".

More correct to me looks a version-string (here: "1:10.0.1~+rc3-1"):

(1:)10.0.1~rc3-1 (dropping "+" after "~")

To be read:
upstream-version: 10.0.1
"rc" release-no:  rc3
debian-revision:  1

As pointed out by Sylvestre in [3] he is trying to keep packages in the Debian repositories
in balance with <apt.llvm.org>.

As I am interested in having the best packages in Debian I am reporting here not upstream.

Thanks.
