Hello All!
This series introduces a way to check hashes prior to doing a download.
This is required for when upstream silently update their release tarballs
without renaming them, and the user is left with a stray locally cached
tarball that no longer match the hashes with have for that package.
In so doing, this series:
- moves the check for a cached file into the wrapper;
- moves the post-download check for hashes into the wrapper;
- adds a pre-download check for hashes in the wrapper.
Doing the pre-download checks in the Makefile, like the post-download
checks were done, made the Makefile a bit harder to read. On the other
hand, we have a download wrapper shell script, so it is easier to do
trickey stuff in there (shell syntax) than in the Makefile (make syntax
can become unreadable pretty fast).
This has a side effect of cleaning up the pkg-download.mk Makefile, too,
but that was not the goal.
Changes v1 -> v2:
- add options parsing to the wrapper (Thomas)
- typoes (Thomas)
- rename the wrapper to dl-wrapper so it looks better in the traces,
and it is not confused with another wrapper
Regards,
Yann E. MORIN.
