Hi, Here goes version 5. I decided to start with a very very minimal working version that is only 124 lines of code, then slowly but steadily introduce all the fancy features. I also tweaked the defaults so they give more meaninful results (IMO). I also fixed the parsing of diffs so that it tackles corner case Junio mentioned. This script allows you to get a list of relevant persons to Cc when sending a patch series. % git related v1.8.1.6^^1..v1.8.1.6^^2 Junio C Hamano <gitster@xxxxxxxxx> (signer: 92%, author: 7%) Nguyễn Thái Ngọc Duy <pclouds@xxxxxxxxx> (author: 38%) Michael Haggerty <mhagger@xxxxxxxxxxxx> (author: 15%) It finds people that might be interesting in a patch, by going back through the history for each single hunk modified, and finding people that reviewed, acknowledged, signed, or authored the code the patch is modifying. It does this by running 'git blame' incrementally on each hunk, and then parsing the commit message. After gathering all the relevant people, it groups them to show what exactly was their role when the participated in the development of the relevant commit, and on how many relevant commits they participated. They are only displayed if they pass a minimum threshold of participation. The code finds the changes in each commit in the list, runs 'git blame' to see which other commits are relevant to those lines, and then adds the author and signer to the list. Finally, it calculates what percentage of the total relevant commits each person was involved in, and if it passes the threshold, it goes in. You can also choose to show the commits themselves: % git related --commits v1.8.1.6^^1..v1.8.1.6^^2 9db9eec attr: avoid calling find_basename() twice per path 94bc671 Add directory pattern matching to attributes 82dce99 attr: more matching optimizations from .gitignore 593cb88 exclude: split basename matching code into a separate function b559263 exclude: split pathname matching code into a separate function 4742d13 attr: avoid searching for basename on every match f950eb9 rename pathspec_prefix() to common_prefix() and move to dir.[ch] 4a085b1 consolidate pathspec_prefix and common_prefix d932f4e Rename git_checkattr() to git_check_attr() 2d72174 Extract a function collect_all_attrs() 8cf2a84 Add string comparison functions that respect the ignore_case variable. 2c5b011 dir.c: Fix two minor grammatical errors in comments 377d9c4 Makefile: update the default build options for AIX But wait, there's more: you can also specify a list of patch files, which means this can be used for 'git send-emails' --cc-cmd option. I don't know about you, but I've found this script incredibly useful.
