Subject: [pbs-devel] [RFC v2 pxar 06/36] encoder: move to stack based state tracking
Date: Tue,  5 Mar 2024 10:26:33 +0100	[thread overview]
Message-ID: <20240305092703.126906-7-c.ebner@proxmox.com> (raw)
In-Reply-To: <20240305092703.126906-1-c.ebner@proxmox.com>

In preparation for the proxmox-backup-client look-ahead caching,
where a passing around of different encoder instances with internal
references is not feasible.

Instead of creating a new encoder instance for each directory level
and keeping references to the parent state, use an internal stack.

This is a breaking change in the pxar library API.
