Epubcheck misses error

exaltedwombat · 09-24-2019, 04:56 AM

How is this possible? (I'd just run Epubcheck).

Flightcrew detects the error.

How is it possible we'd be able to investigate with the info given?

In general, I'd say it's NOT possible. EpubCheck isn't going to miss a tag mismatch. So something else must be going on. A flush to disk not happening, a stale file, etc... . Without a reproducible sample, there's no way to diagnose.

New epub file. I enter this code. I save the file, refusing the offer to fix it. Preview catches the error. FlightCrew catches the error. EpubCheck returns 'No problem found'.

Windows 10. Sigil 0.9.18. EpubCheck 4.22.

Code:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"

Solved by re-installing EpubCheck. Still shows as EpubCheck 4.22 when running, but the wrapper version in Manage Plugins has updated to 0.4.2.

I'm running an older version of the epubcheck plugin (0.4.1.2) and can't duplicate the issue. EpubCheck flags the mismatch every time.

What version Sigil is being used where epubcueck failed?

Perhaps if you read the thread.....

Sorry, I didn't go back and check.

Yes, if epubcheck fails to run due to java issues or throws an exception, it will come back with "no problems found".

If you enable the epubcheck json preference to copy the output to the clipboard, you can paste it into any text editor to see the exact exception thrown.

Perhaps we can work with Doitsu to return a -1 from his plugin if any exceptions are thrown.

Currently, the plugin only checks for Stack Overflow errors:

Code:

    # check for StackOverflowError error
    if stderr.find('java.lang.StackOverflowError') != -1:
        print('EPUBCheck Java error.\n', stderr)
        return -1

What other common Java error messages should I check for and how did you trigger them for testing purposes?

KevinH · 09-24-2019, 03:54 PM

I had too old a version of java installed (1.6) and epubcheck threw an exception. I will try to recreate that and get you a copy.

KevinH · 09-24-2019, 03:56 PM

How hard would it be to search stderr for the words exception or error and report back all it finds to be safe?

KevinH · 09-24-2019, 04:02 PM

Here is a report that looks identical to what I found in the clipboard after running epubcheck:
