Comparing 2 blobs This Python script would be simple and fairly efficient in the common case (assuming Zope Fileish objects): ##parameters=file1, file2 return file1.get_size() == file2.get__size() or str(file1) == str(file2) It would only be inefficient for large files that were exactly the same size, which would be uncommon methinks. To make that case efficient, you would need to precompute a checksum at upload time and store it as a property for comparison. On Friday 28 March 2003 03:33 pm, Bobb wrote:
Does anyone know of a "reliable" way to compare blobs in python / zope... I'm looking a either comparing the first # of characters, or crc check or something.
TIA
