Re: [Kimchi-devel] [kimchi-devel][PATCHv3 5/6] Fix incomplete record when uploading

From: Royce Lv <lvroyce(a)linux.vnet.ibm.com&gt; When uploading an ISO file, the ISO distro record may be incomplete because uploading in progress. "call_stack":"Traceback (most recent call last): File \"./src/kimchi/model/storagevolumes.py\", line 304, in lookup iso_img = IsoImage(path) File \"./src/kimchi/isoinfo.py\", line 149, in __init__ self._scan() File \"./src/kimchi/isoinfo.py\", line 437, in _scan self._scan_el_torito(data) File \"./src/kimchi/isoinfo.py\", line 218, in _scan_el_torito ident, csum, key55, keyAA) = self._unpack(fmt, tmp_data) File \"./src/kimchi/isoinfo.py\", line 181, in _unpack return s.unpack(data[:s.size]) error: unpack requires a string argument of length 32\n" So wrap reading record with error handling so that error will not occur in uploading.
