Errors when ingesting these files #245
Comments
|
Update... these errors are NOT from EPUBCheck 5. Details: pub-foreign_bad-fallback pub-foreign_json-spine these are errors specific to the VST ingestion workflow, not EPUBCheck. Essentially if there's a spine item, we expect it to be HTML/XHTML, and if we are trying to parse files like DMG and JSONs in there, these files will never ingest into our system. Is this expected behavior? |
|
Several of the tests involve deliberately-invalid EPUBs in order to test aspects of the specification. Some of the deliberate errors are quite extreme, for example to test what happens in fallback chains. I fully expect some of these files to not work in various reading systems--in fact I hope they don't. |

should those we expect to fail be identified in the contributing guide for testing? At least the tester could know to look for other options (like side loading) for testing |

I agree. I would think that a very explicit statement should be present in the 'description' field in the package file (which is then taken over on the test description). @dauwhe, as far as I could see, these are your tests, could you add such descriptions to the metadata? I am afraid if I do those, I may misunderstand the exact goals of the tests... |

@dauwhe, if you can't do it I will do something... sometimes in the coming days. |
I have looked at these. I have created PR #246 adding a remark in the package file of the first two cases, whereby an RS may reject the respective EPUB document altogether. In my view, the RS does pass the test in that case. I do have a problem with the third case, though. What happens there is that the spine item is a JSON file but a fallback is also specified for it to a bona fide HTML file. In my view, this is a correct EPUB document per spec, but it is based on the assumption that the RS implements the fallback. Put it another way, the RS error message shows that the RS does not implement fallbacks, which means that the test should fail. Cc-ing the other testers here, too, to check whether my view is correct... |

I was also looking at the other three cases ( I think this falls under a situation we have already discussed elsewhere; these tests are aimed at RS-s that allow sideloading, and they should react in some proper way to those errors. On the other hand, it is understood that some RS-s are solely based on an ingestion flow that includes epubcheck; this is one of the situations for which we introduced lately the "n/a" (for "non-applicable") case in the test report. I guess this is exactly your case for those tests, @rickj. |
|
Finishing up our testing, and applying 'n/a' for files that fail epubcheck, however, for files that pass epubcheck but do not open in a reading system, is 'n/a' the appropriate test result also? |
|
Are these the cases when the test relies on fallback but they do not open because fallback is not implemented? If that is the case then, I am afraid, the tests fail due to missing functionalities... |
Possibly. We will do more testing for these as side loaded and update where needed. Right now not passing epubcheck prevents them from even getting to the reading system |
Ah. That was not clear to me. Based on what you told before, that would mean a "n/a" then, because your implementation does not have side loading and everything is filtered through epubcheck... |
When ingesting all of the tests, and using EPUBCheck 5.0.0 beta, these errors were observed:
