[pbs-devel] [PATCH v3 proxmox-backup 00/10] fix catalog dump and shell for split pxar archives

[Christian Ebner]

This patch series fixes the `catalog dump` and `catalog shell`
commands for snapshots created by setting the `change-detection-mode`
to either `data` or `metadata`, therefore using split pxar archive
encoding without encoding the dedicated catalog.

If no catalog file can be found in the snaphsots manifest, the fallback
behaviour is now to check if there are metadata archives present in the
manifest, and if so use the metadata archive accessor for either
dumping the contents in a format compatible to the catalog dump or to
interactively navigate and restore contents via the catalog shell.

Changes since version 2 (thanks to Fabian for the comments and
suggestions):
- Move and factor out helpers to pxar/tools submodule instead of using
  the tools module, which is for more generally client tools.
- Improve error handling in catalog shell by avoiding unwrap of missing
  directory stack entries, bail instead.
- fix issue with factoring out of `entry_path_with_prefix` helper
- Convert to `DirEntryAttribute` by implementing the `TryFrom` trait,
  replacing previous helper.

Changes since version 1:
- Implement also the `catalog shell` command for split pxar archives
- Factor out common functionality into dedicated helpers

Christian Ebner (10):
  client: tools: make tools module public
  client: pxar: move catalog lookup helper to pxar tools
  client: tools: move pxar root entry helper to pxar submodule
  client: make helper to get remote pxar reader reusable
  client: tools: factor out entry path prefix helper
  client: tools: factor out pxar entry to dir entry mapping
  client: add helper to dump catalog from metadata archive
  client: catalog: fallback to metadata archives for catalog dump
  client: helper to mimic catalog find using metadata archive
  client: catalog shell: fallback to accessor for navigation
