The "test-parse-all-blobs" command:

Usage: fossil test-parse-all-blobs ?OPTIONS?

Parse all entries in the BLOB table that are believed to be non-data artifacts and report any errors. Run this test command on historical repositories after making any changes to the manifest_parse() implementation to confirm that the changes did not break anything.

Options:

--limit N

Parse no more than N artifacts before stopping

--wellformed

Use all BLOB table entries as input, not just those entries that are believed to be valid artifacts, and verify that the result the manifest_is_well_formed() agrees with the result of manifest_parse().
