That's the closest I can come to think of. The trouble with --decorate is that you have to manually find the decorated commit that is closest. That can be hard if you have a lot of commits. There is also --source, which will transmit the source name down from parent to child. So if you do: git log --all --source each tip will be painted with its ref name, and will pass that to its ancestors as we walk the graph. Of course ancestors that have multiple children (e.g., something that got merged) will only show one source, but that painting will never cross an actual branch boundary (so if branch A merged branch B, the commits that are in B will still get painted as B). The big downside is that you are now traversing _all_ refs, instead of just the ones you wanted. We could fix that by letting you specify a set of refs to paint. For example, with the patch below, you can do: git log --source=refs/heads and see only commits in HEAD, but painted by their source in refs/heads/*. I'm not planning to work on it further anytime soon, but if somebody wants to pick it up and run with it, feel free. I think before inclusion one would want to consider: 1. Calling it --contains instead of --source, since it is not really about the source anymore. 2. Moving the storage out of commit-util into a commit-slab. This would prevent it from conflicting with --source (for that matter, it would be nice if --source used a slab, too). 3. Rather than showing one arbitrary way of getting to the commit, keep track of _all_ of them. Unfortunately this is not quite a true list of which refs contain the commit, as we might show the commit before its parent paints down to it (this can happen if the commit timestamps are out of order, I think). We could get around that by using --topo-order. 4. Make the output less ugly (probably more like --decorate, with colors and parentheses). --- diff --git a/builtin/log.c b/builtin/log.c index a7ba211..8ad7b46 100644 --- a/builtin/log.c +++ b/builtin/log.c @@ -25,6 +25,7 @@ #include version.h #include mailmap.h #include gpg-interface.h +#include refs.h /* Set a default date-time format for git log (log.date config variable) */ static const char *default_date_mode = NULL; @@ -116,16 +117,61 @@ static void cmd_log_init_defaults(struct rev_info *rev) rev-diffopt.touched_flags = 0; } +struct source_opt { + struct string_list refs; + int enabled; +}; + +static int parse_opt_source(const struct option *opt, const char *arg, int unset) +{ + struct source_opt *source = opt-value; + + if (unset) { + source-enabled = 0; + string_list_clear(source-refs, 0); + } else { + source-enabled = 1; + if (arg) + string_list_append(source-refs, arg); + } + + return 0; +} + +static int paint_source_ref(const char *refname, const unsigned char *sha1, + int flags, void *data) +{ + const char *prefix = data; + struct commit *c = lookup_commit_reference_gently(sha1, 1); + + if (c !c-util) { + struct strbuf buf = STRBUF_INIT; + strbuf_addstr(buf, prefix); + strbuf_addstr(buf, refname); + c-util = strbuf_detach(buf, NULL); + } + return 0; +} + +static int paint_source_refs_in(struct string_list_item *it, void *data) +{ + for_each_ref_in(it-string, paint_source_ref, it-string); + return 0; +} + + static void cmd_log_init_finish(int argc, const char **argv, const char *prefix, struct rev_info *rev, struct setup_revision_opt *opt) { struct userformat_want w; - int quiet = 0, source = 0, mailmap = 0; + struct source_opt source = { STRING_LIST_INIT_DUP, 0 }; + int quiet = 0, mailmap = 0; static struct line_opt_callback_data line_cb = {NULL, NULL, STRING_LIST_INIT_DUP}; const struct option builtin_log_options[] = { OPT__QUIET(quiet, N_(suppress diff output)), - OPT_BOOL(0, source, source, N_(show source)), + { OPTION_CALLBACK, 0, source, source, N_(refs), N_(show source), + PARSE_OPT_OPTARG, parse_opt_source }, OPT_BOOL(0, use-mailmap, mailmap, N_(Use mail map file)), { OPTION_CALLBACK, 0, decorate, NULL, NULL, N_(decorate options), PARSE_OPT_OPTARG, decorate_callback}, @@ -164,8 +210,10 @@ static void cmd_log_init_finish(int argc, const char **argv, const char

I have not tried that command. Note I mentioned named refs, so nameless branches I'm not worried about. Even if I merge branch A into branch B, branch A is still closest in terms of number of steps to get to the commit, because to get to the commit through B you have to cross over a merge commit. Basically the priority should be directness and distance. The more direct a branch is (i.e. the lesser number of merge commits it goes through to get to the commit) the more relevant it is. As a second condition, distance would be used in cases where the directness of it is the same. Sorting this in the log graph and seeing it visually (I could even use --simplify-by-decoration) would help me understand the topography of git's history relative to the commit(s) I specify. -- To unsubscribe from this list: send the line unsubscribe git in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
