[pve-devel] [PATCH v3 proxmox-perl-rs] move apt repositories module to common

Fabian Ebner f.ebner at proxmox.com
Fri Jul 8 13:55:53 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 v2:
    * Turn Rust side into wrappers rahter than adding Perl wrappers.
    * Avoid moving files between packages.

pve-manager (respectively pmg-api) depends and build-depends on
libproxmox-rs-perl and libpve-rs-perl (respectively libpmg-rs-perl).
Both are needed, because just upgrading libproxmox-rs-perl doesn't
make the new functionality available in the product-specific shared
lib.
