Bug in -diff - missing differences

[ywzc]

I found a possible bug in the -diff option. It doesn't show all differences.

What I did:

Code Select Expand

exiftool -wm cg -@ iptc2xmp.args -IPTC:All= IMAGE.JPG
I than ran:

Code Select Expand

exiftool -s -a -u --System:All IMAGE.JPG -diff IMAGE.JPG_original
The output was:

Code Select Expand

> [File]          CurrentIPTCDigest               : 0cc2bded349bddded77246167d550ccf
< [XMP-dc]        Creator                         : Picasa 2.6But exiftool -s -G1 -IPTC:All IMAGE.JPG IMAGE.JPG_original shows:

Code Select Expand

======== IMAGE.JPG
======== IMAGE.JPG_original
[IPTC]          By-line                         : Picasa 2.6

Thanks for this report!

I can reproduce this problem and will post back when I know more.

I've found the problem, and ExifTool 13.16 will fix this issue.

It seems that one tag was dropped from the output for groups that exist in the diff file but not the source file.

Thanks again for the report.
