First: in Documentation/diffcore.txt there is an example of broken pair diffcore-break: For Splitting Up "Complete Rewrites" ---------------------------------------------------- The second transformation in the chain is diffcore-break, and is controlled by the -B option to the git-diff-* commands. This is used to detect a filepair that represents "complete rewrite" and break such filepair into two filepairs that represent delete and create. E.g. If the input contained this filepair: ------------------------------------------------ :100644 100644 bcd1234... 0123456... M file0 ------------------------------------------------ and if it detects that the file "file0" is completely rewritten, it changes it to: ------------------------------------------------ :100644 000000 bcd1234... 0000000... D file0 :000000 100644 0000000... 0123456... A file0 ------------------------------------------------ Shouldn't the last block read for the modern git read: ------------------------------------------------ :100644 000000 bcd1234... 0123456... M99 file0 ------------------------------------------------ or is it only for '-B' togehter with '-M' or '-C'? Second: do you have per chance good examples of broken (and perhaps merged together) pair, such that it is affected by --diff-filter=B; with -B<num> or -B<num1>/<num2> parameters needed, if required. COPYING and Makefile are one good example, but do you have literal files with similar behavior? Third: Do "git diff --no-index" (filesystem diff) can show breaking / use dissimilarity? I couldn't make it work... -- Jakub Narebski Poland - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
