+qemu-img convert is freezing for some DMG files.
+
+Recently, I created a file using hdiutil from MacOS (using Zlib compression):
+
+$ hdiutil create -volname MyVolName -srcfolder /path/to/my/vol/ -ov -format UDZO myvolname.dmg
+
+But, when I try to convert this volume using qemu-img convert, this command is freezing.
+
+I'm using the upstream version to test it.
+
+It is freezing inside the binary search method to retrieve the chunk.
+
+But, I still don't know why.
+
+I'm attaching the file as an example.
+
+It can be mounted using MacOS or other Linux apps like hfsleuth and darling-dmg.
+
+
+
+I have submitted a patch to prevent hanging in binary search.
+See: http://lists.nongnu.org/archive/html/qemu-devel/2018-12/msg05453.html?fbclid=IwAR0ObsaZ4kVMVv6MWIdq0ZCAN5tGhDsd9GmFv8_v7HBTl94Cu5EkRZ3z4n4

+Thanks,

+
+I'm almost sure that we need other improvements beyond fixing binary search deadlock.
+
+It is returning read errors when you apply your patch.
+
+Because of lacking zero chunk table, reading zero sector will return EIO.
+I have submitted a series to fix this problem.
+
+Please refer to this series: http://lists.nongnu.org/archive/html/qemu-devel/2018-12/msg05637.html

+
+Hi Yu-Chen.
+
+The series looks good. It fixed the problems related to zero chunk. Nice work!
+
+I added a comment that I reviewed your patch considering my scenarios here. At least, It contributes to merge your changes.
+
+Additional info: tested with version 3.0.0. So, before pushing my commits. Conclusion: This is not a new bug.
+
+Since QEMU 4.0 has been released now, I assume we can close this ticket as "Fix released"? Or is there still anything left to do here?
+
+I re-test the dmg img with QEMU 4.0 again, and it works.
+
+In my opinion, the bug can be closed as "Fix released".
+
+Thanks.
+
+
+
+Thanks for testing. So I'm marking this now as "Fix released".
