Fuse mounts for split pxar archives currently greatly suffer from the
consistency check between metadata and payload data archives, as
these happen already during decoding of the payload reference entry
in the metadata archive. 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 2:
- Make helper and ContentRange pub(crate) only
- Fix typo in commit message
- Move incorrectly squashed cargo fmt patch into own patch
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 (5):
accessor: fix minor formatting issue
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
