There are more details I can get with the files like the 7z exit
code(s) and results from other test tools, but thanks for the info.
Both finds were exactly what I was looking for in outside testing.
A basic test adding a comment via "zip -z" tested file with 7z:
=============================================================================
Type = zip
Physical Size = 40819112
Comment =
{"ComicBookInfo/1.0":{"publicationYear":1985,"genre":"Superhero","volume":1,"series":"Fantastic
Four","issue":"274","rating":0,"publisher":"Marvel","publicationMonth":1,"country":"United
States","language":"English","title":"Fantastic Four 274 (c2c)"},"app
ID":"ComicBookLover/1291","lastModified":"2013-04-30 15:41:05 +0000"}
Everything is Ok
Folders: 1
Files: 55
Size: 40901027
Compressed: 40819112
==============================================================================
Looks like ComicBookLover screwed up the zip comment.
I did some further testing with the two "corrupt" files you posted. I'm
beginning to think there is a bug in rar/unrar (v5.70, latest
non-beta). WINRAR reports both archives as OK (same as 7x using the
unrar dll). The fact that the GUI app (which is the grandaddy of all
rar) says the archives are OK strongly indicates that the phantom
errors (no details) from rar/unrar are bogus.
So change of plans. I'll amend the test_archive code to disregard the
"errors" when all items test as OK. And add a check for data at the end
of zip archives that begin with '{"ComicBookInfo'.
