NOT READY: warcio test #66

wumpus · 2019-01-26T00:26:25Z

An opinionated WARC standards-conformance tool.

Ready for review - I have yet to work on test coverage.

$ warcio test test/data/*.warc.gz test/data/*.warc
test/data/example-bad-non-chunked.warc.gz
  saw exception 
    ERROR: non-chunked gzip file detected, gzip block continues
    beyond single record.

    This file is probably not a multi-member gzip but a single gzip file.

    To allow seek, a gzipped WARC must have each record compressed into
    a single gzip member and concatenated together.

    This file is likely still valid and can be fixed by running:

    warcio recompress <path/to/file> <path/to/new_file>
  skipping rest of file

The existing code did the bug fixup unconditionally, I'm preserving that default.

digest checking defaults off because it's expensive and @ikreymer prefers people remain in the dark as to how many invalid warcs there are :-)

@N0taN3rd has done a preliminary review, the main addition since then is some global checks.

At this point I think the code is feature-complete, well, for the things I'm planning for the first pass, and the main work remaining is coverage.
