More details on errors

[rgaudin]

Just realized that our fondamentaux ZIM was drastically smaller than it should (and previously was): 2.35 GB and 2.54 GB instead of 9.36 GB.
Those numbers were from three different runs a few days apart (Nov 4th – large one, Nov 6th and Nov 10th).

With an exit-code of 0, we had no idea those newer ZIMs were problematic.

Understanding we can't fail on every single error when scraping a generic website, we could still be a little smarter by recording and exposing the number of failed fetches so that our QA process can evaluate whether the output is OK or not.

@ikreymer, how realistic is adding a count of succeeded/failed fetches? I think the error count in stdout only regards the webpages, right ? Those runs didn't had any 1513 / 1513 (100.00%), errors: 0 (0.00%).
