From: Linus Torvalds Date: Thu, 26 May 2005 01:29:09 +0000 (-0700) Subject: git-rev-list: add "end" commit and "--header" flag X-Git-Tag: v0.99~455 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=a6f68d4767835d5720cff61785b93eaf99376241;p=git.git git-rev-list: add "end" commit and "--header" flag The "end" commit is just faking it right now, it's sorting things purely by date, so this is _not_ a reachability analysis. Some day. The "--header" flag causes the commit message to be printed out, with a NUL character separator after it for parseability. This allows you to do things like use "grep -z" to grep for certain authors etc. --- diff --git a/rev-list.c b/rev-list.c index 94e52d2ed..93bee1962 100644 --- a/rev-list.c +++ b/rev-list.c @@ -1,45 +1,70 @@ #include "cache.h" #include "commit.h" +static const char rev_list_usage[] = + "usage: git-rev-list [OPTION] commit-id \n" + " --max-count=nr\n" + " --max-age=epoch\n" + " --min-age=epoch\n" + " --header"; + int main(int argc, char **argv) { - unsigned char sha1[20]; + int nr_sha; + unsigned char sha1[2][20]; struct commit_list *list = NULL; - struct commit *commit; - char *commit_arg = NULL; - int i; + struct commit *commit, *end; + int i, verbose_header = 0; unsigned long max_age = -1; unsigned long min_age = -1; int max_count = -1; + nr_sha = 0; for (i = 1 ; i < argc; i++) { char *arg = argv[i]; if (!strncmp(arg, "--max-count=", 12)) { max_count = atoi(arg + 12); - } else if (!strncmp(arg, "--max-age=", 10)) { + continue; + } + if (!strncmp(arg, "--max-age=", 10)) { max_age = atoi(arg + 10); - } else if (!strncmp(arg, "--min-age=", 10)) { + continue; + } + if (!strncmp(arg, "--min-age=", 10)) { min_age = atoi(arg + 10); - } else { - commit_arg = arg; + continue; } + if (!strcmp(arg, "--header")) { + verbose_header = 1; + continue; + } + + if (nr_sha > 2 || get_sha1(arg, sha1[nr_sha])) + usage(rev_list_usage); + nr_sha++; } - if (!commit_arg || get_sha1(commit_arg, sha1)) - usage("usage: git-rev-list [OPTION] commit-id\n" - " --max-count=nr\n" - " --max-age=epoch\n" - " --min-age=epoch\n"); + if (!nr_sha) + usage(rev_list_usage); - commit = lookup_commit(sha1); + commit = lookup_commit_reference(sha1[0]); if (!commit || parse_commit(commit) < 0) - die("bad commit object"); + die("bad starting commit object"); + + end = NULL; + if (nr_sha > 1) { + end = lookup_commit_reference(sha1[1]); + if (!end || parse_commit(end) < 0) + die("bad ending commit object"); + } commit_list_insert(commit, &list); do { struct commit *commit = pop_most_recent_commit(&list, 0x1); + if (commit == end) + break; if (min_age != -1 && (commit->date > min_age)) continue; if (max_age != -1 && (commit->date < max_age)) @@ -47,6 +72,8 @@ int main(int argc, char **argv) if (max_count != -1 && !max_count--) break; printf("%s\n", sha1_to_hex(commit->object.sha1)); + if (verbose_header) + printf("%s%c", commit->buffer, 0); } while (list); return 0; }
