[pbs-devel] [PATCH v6 proxmox-backup 0/4] fix #2996: client: allow optional match patterns for restore

[Christian Ebner]

This patches implement the api types to allow input validation for
pathpatterns and reuse them in the pxar-bin, the catalog shell as
well as the newly exposed optional restore patterns to the backup
clients restore command.

Patterns are parsed and passed along to the preexisting restore
logic via the `PxarExtractOptions`.

To correctly work also with split pxar archives, this patches depend
on the following patch being applied to the pxar repo first:
https://lore.proxmox.com/pbs-devel/20240918150047.485551-1-c.ebner@proxmox.com/

changes since version 5:
- rebased onto current master

changes since version 4:
- rebased onto current master
- fixed passing patterns via cli for pxar extract

changes since version 3:
- s/matches/patterns for bail message, thanks for testing and
  catching this Gabriel!

changes since version 2:
- added API types as suggested
- reuse same API types for proxmox-backup-client catalog shell and
  restore as well as the pxar extract
- use simple reference instead of `as_slice()` when passing vector of
  patterns

[pbs-devel] [PATCH v6 proxmox-backup 1/4] api-types: implement dedicated api type for match patterns

[Christian Ebner]

Introduces a dedicated api type `PathPattern` and the corresponding
format and input validation schema. Further, add a `PathPatterns`
type for collections of path patterns and implement required traits
to be able to replace currently defined api parameters.

In preparation for using this common api type for all api endpoints
exposing a match pattern parameter.

[pbs-devel] [PATCH v6 proxmox-backup 4/4] fix #2996: client: allow optional match patterns for restore

[Christian Ebner]

When the user is only interested in a subset of the entries stored in
a file-level backup, it is convenient to be able to provide a list of
match patterns for the entries intended to be restored.

The required restore logic is already in place. Therefore, expose it
for the `proxmox-backup-client restore` command by adding the optional
array of patterns as command line argument and parse these before
passing them via the pxar restore options to the archive extractor.

[Fabian Grünbichler]

Consider this

Reviewed-by: Fabian Grünbichler <f.gruenbichler@proxmox.com>
Tested-by: Fabian Grünbichler <f.gruenbichler@proxmox.com>

but I'd like to add the following on-top, unless you object:

Subject: [PATCH proxmox-backup] api types: replace PathPatterns with Vec<PathPattern>

PathPatterns is hard to distinguish from PathPattern, so would need to be
renamed anyway.. but there isn't really a reason to define a separate API type
just for this.
