By moving this check to the content reader instantiation, the performance can be improved significantly, as now the payload data chunks only need to be fetched and decoded when actually accessing the file payloads. Changes since version 1: - Add previously missing check when accessing contents via the accessor instead of the decoder. - Add missing context and refactor file entry extraction branch in pxar extract according to suggestions pxar: Christian Ebner (4): format: add helper for payload header consistency checks format: add helper type ContentRange decoder: move payload header check for split input accessor: add payload checks for split archives src/accessor/aio.rs | 15 ++++++----- src/accessor/mod.rs | 60 +++++++++++++++++++++++++++++++++----------- src/accessor/sync.rs | 16 ++++++------ src/decoder/aio.rs | 4 +-- src/decoder/mod.rs | 56 +++++++++++++++++++++++------------------ src/decoder/sync.rs | 5 ++-- src/format/mod.rs | 32 +++++++++++++++++++++++ 7 files changed, 132 insertions(+), 56 deletions(-) proxmox-backup: Christian Ebner (1): client: pxar: fix fuse mount performance for split archives pbs-client/src/pxar/extract.rs | 62 ++++++++++++++++------------------ pbs-pxar-fuse/src/lib.rs | 14 ++++---- src/api2/tape/restore.rs | 2 +- 3 files changed, 37 insertions(+), 41 deletions(-) -- 2.39.2 _______________________________________________ pbs-devel mailing list pbs-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pbs-devel
