From e827633a5d7d627eb1170b2d0c71e944d0d56faf Mon Sep 17 00:00:00 2001 From: Rene Scharfe Date: Tue, 24 Oct 2006 01:01:57 +0200 Subject: Built-in cherry This replaces the shell script git-cherry with a version written in C. The behaviour of the new version differs from the original in two points: it has no long help any more, and it is handling the (optional) third parameter a bit differently. Basically, it does the equivalent of ours=`git-rev-list $ours ^$limit ^$upstream` instead of ours=`git-rev-list $ours ^$limit` Signed-off-by: Rene Scharfe Signed-off-by: Junio C Hamano diff --git a/Makefile b/Makefile index 66c8b4b..2b53747 100644 --- a/Makefile +++ b/Makefile @@ -157,7 +157,7 @@ BASIC_LDFLAGS = SCRIPT_SH = \ git-bisect.sh git-branch.sh git-checkout.sh \ - git-cherry.sh git-clean.sh git-clone.sh git-commit.sh \ + git-clean.sh git-clone.sh git-commit.sh \ git-fetch.sh \ git-ls-remote.sh \ git-merge-one-file.sh git-parse-remote.sh \ @@ -210,7 +210,7 @@ PROGRAMS = \ EXTRA_PROGRAMS = BUILT_INS = \ - git-format-patch$X git-show$X git-whatchanged$X \ + git-format-patch$X git-show$X git-whatchanged$X git-cherry$X \ git-get-tar-commit-id$X \ $(patsubst builtin-%.o,git-%$X,$(BUILTIN_OBJS)) diff --git a/builtin-log.c b/builtin-log.c index 9d1ceae..fc5e476 100644 --- a/builtin-log.c +++ b/builtin-log.c @@ -437,3 +437,109 @@ int cmd_format_patch(int argc, const char **argv, const char *prefix) return 0; } +static int add_pending_commit(const char *arg, struct rev_info *revs, int flags) +{ + unsigned char sha1[20]; + if (get_sha1(arg, sha1) == 0) { + struct commit *commit = lookup_commit_reference(sha1); + if (commit) { + commit->object.flags |= flags; + add_pending_object(revs, &commit->object, arg); + return 0; + } + } + return -1; +} + +static const char cherry_usage[] = +"git-cherry [-v] [] []"; +int cmd_cherry(int argc, const char **argv, const char *prefix) +{ + struct rev_info revs; + struct diff_options patch_id_opts; + struct commit *commit; + struct commit_list *list = NULL; + const char *upstream; + const char *head = "HEAD"; + const char *limit = NULL; + int verbose = 0; + + if (argc > 1 && !strcmp(argv[1], "-v")) { + verbose = 1; + argc--; + argv++; + } + + switch (argc) { + case 4: + limit = argv[3]; + /* FALLTHROUGH */ + case 3: + head = argv[2]; + /* FALLTHROUGH */ + case 2: + upstream = argv[1]; + break; + default: + usage(cherry_usage); + } + + init_revisions(&revs, prefix); + revs.diff = 1; + revs.combine_merges = 0; + revs.ignore_merges = 1; + revs.diffopt.recursive = 1; + + if (add_pending_commit(head, &revs, 0)) + die("Unknown commit %s", head); + if (add_pending_commit(upstream, &revs, UNINTERESTING)) + die("Unknown commit %s", upstream); + + /* Don't say anything if head and upstream are the same. */ + if (revs.pending.nr == 2) { + struct object_array_entry *o = revs.pending.objects; + if (hashcmp(o[0].item->sha1, o[1].item->sha1) == 0) + return 0; + } + + get_patch_ids(&revs, &patch_id_opts, prefix); + + if (limit && add_pending_commit(limit, &revs, UNINTERESTING)) + die("Unknown commit %s", limit); + + /* reverse the list of commits */ + prepare_revision_walk(&revs); + while ((commit = get_revision(&revs)) != NULL) { + /* ignore merges */ + if (commit->parents && commit->parents->next) + continue; + + commit_list_insert(commit, &list); + } + + while (list) { + unsigned char sha1[20]; + char sign = '+'; + + commit = list->item; + if (!get_patch_id(commit, &patch_id_opts, sha1) && + lookup_object(sha1)) + sign = '-'; + + if (verbose) { + static char buf[16384]; + pretty_print_commit(CMIT_FMT_ONELINE, commit, ~0, + buf, sizeof(buf), 0, NULL, NULL, 0); + printf("%c %s %s\n", sign, + sha1_to_hex(commit->object.sha1), buf); + } + else { + printf("%c %s\n", sign, + sha1_to_hex(commit->object.sha1)); + } + + list = list->next; + } + + return 0; +} diff --git a/builtin.h b/builtin.h index f71b962..285d98f 100644 --- a/builtin.h +++ b/builtin.h @@ -19,6 +19,7 @@ extern int cmd_archive(int argc, const char **argv, const char *prefix); extern int cmd_cat_file(int argc, const char **argv, const char *prefix); extern int cmd_checkout_index(int argc, const char **argv, const char *prefix); extern int cmd_check_ref_format(int argc, const char **argv, const char *prefix); +extern int cmd_cherry(int argc, const char **argv, const char *prefix); extern int cmd_commit_tree(int argc, const char **argv, const char *prefix); extern int cmd_count_objects(int argc, const char **argv, const char *prefix); extern int cmd_diff_files(int argc, const char **argv, const char *prefix); diff --git a/git-cherry.sh b/git-cherry.sh deleted file mode 100755 index 8832573..0000000 --- a/git-cherry.sh +++ /dev/null @@ -1,91 +0,0 @@ -#!/bin/sh -# -# Copyright (c) 2005 Junio C Hamano. -# - -USAGE='[-v] [] []' -LONG_USAGE=' __*__*__*__*__> - / - fork-point - \__+__+__+__+__+__+__+__> - -Each commit between the fork-point (or if given) and is -examined, and compared against the change each commit between the -fork-point and introduces.
