[pve-devel] [PATCH v2 proxmox-perl-rs] move apt repositories module to common

Fabian Ebner f.ebner at proxmox.com
Thu Jul 7 12:38:42 CEST 2022


while introducing a 'product' parameter to the relevant functions and
adding wrappers for backwards-compatibility.

Suggested-by: Wolfgang Bumiller <w.bumiller at proxmox.com>
Signed-off-by: Fabian Ebner <f.ebner at proxmox.com>
---

Changes from v1:
    * Add wrappers, so we can defer the Breaks to later.
    * Drop unnecessary changes in Proxmox/Lib/Common.pm

libproxmox-perl-rs needs a depends/breaks+replaces with both
libpve-rs-perl and libpmg-rs-perl, because it now includes the
P{MG,VE}/APT/Repositories.pm file.

pve-manager and pmg-api depend and build-depend on libproxmox-rs-perl.
The depends/breaks cycle above then ensures that the new functionality
is available in the product-specific shared lib.
