(The apply +backend used to known as the 'am' backend, but the name led to +confusion as it looks like a verb instead of a noun. Also, the merge +backend used to be known as the interactive backend, but it is now +used for non-interactive cases as well. Both were renamed based on +lower-level functionality that underpinned each.) There are some +subtle differences in how these two backends behave: Empty commits ~~~~~~~~~~~~~ -The am backend drops any "empty" commits, regardless of whether the -commit started empty (had no changes relative to its parent to -start with) or ended empty (all changes were already applied -upstream in other commits). +The apply backend unfortunately drops intentionally empty commits, i.e. +commits that started empty, though these are rare in practice. It +also drops commits that become empty and has no option for controlling +this behavior. -The interactive backend drops commits by default that -started empty and halts if it hits a commit that ended up empty. -The `--keep-empty` option exists for the interactive backend to allow -it to keep commits that started empty. +The merge backend keeps intentionally empty commits. Similar to the +apply backend, by default the merge backend drops commits that become +empty unless -i/--interactive is specified (in which case it stops and +asks the user what to do). The merge backend also has an +--empty={drop,keep,ask} option for changing the behavior of handling +commits that become empty. Directory rename detection ~~~~~~~~~~~~~~~~~~~~~~~~~~ -Directory rename heuristics are enabled in the merge and interactive -backends. Due to the lack of accurate tree information, directory -rename detection is disabled in the am backend. +Due to the lack of accurate tree information (arising from +constructing fake ancestors with the limited information available in +patches), directory rename detection is disabled in the apply backend. +Disabled directory rename detection means that if one side of history +renames a directory and the other adds new files to the old directory, +then the new files will be left behind in the old directory without +any warning at the time of rebasing that you may want to move these +files into the new directory. + +Directory rename detection works with the merge backend to provide you +warnings in such cases. + +Context +~~~~~~~ + +The apply backend works by creating a sequence of patches (by calling +`format-patch` internally), and then applying the patches in sequence +(calling `am` internally). Patches are composed of multiple hunks, +each with line numbers, a context region, and the actual changes. The +line numbers have to be taken with some fuzz, since the other side +will likely have inserted or deleted lines earlier in the file. The +context region is meant to help find how to adjust the line numbers in +order to apply the changes to the right lines. However, if multiple +areas of the code have the same surrounding lines of context, the +wrong one can be picked. There are real-world cases where this has +caused commits to be reapplied incorrectly with no conflicts reported. +Setting diff.context to a larger value may prevent such types of +problems, but increases the chance of spurious conflicts (since it +will require more lines of matching context to apply). + +The merge backend works with a full copy of each relevant file, +insulating it from these types of problems. + +Labelling of conflicts markers +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +When there are content conflicts, the merge machinery tries to +annotate each side's conflict markers with the commits where the +content came from. Since the apply backend drops the original +information about the rebased commits and their parents (and instead +generates new fake commits based off limited information in the +generated patches), those commits cannot be identified; instead it has +to fall back to a commit summary. Also, when merge.conflictStyle is +set to diff3, the apply backend will use "constructed merge base" to +label the content from the merge base, and thus provide no information +about the merge base commit whatsoever. + +The merge backend works with the full commits on both sides of history +and thus has no such limitations. + +Hooks +~~~~~ + +The apply backend has not traditionally called the post-commit hook, +while the merge backend has. However, this was by accident of +implementation rather than by design. Both backends should have the +same behavior, though it is not clear which one is correct. + +Interruptability +~~~~~~~~~~~~~~~~ + +The apply backend has safety problems with an ill-timed interrupt; if +the user presses Ctrl-C at the wrong time to try to abort the rebase, +the rebase can enter a state where it cannot be aborted with a +subsequent `git rebase --abort`. The merge backend does not appear to +suffer from the same shortcoming. (See +https://lore.kernel.org/git/20200207132152.GC2868@szeder.dev/ for +details.) + +Miscellaneous differences +~~~~~~~~~~~~~~~~~~~~~~~~~ + +There are a few more behavioral differences that most folks would +probably consider inconsequential but which are mentioned for +completeness: + +* Reflog: The two backends will use different wording when describing + the changes made in the reflog, though both will make use of the + word "rebase". + +* Progress, informational, and error messages: The two backends + provide slightly different progress and informational messages. + Also, the apply backend writes error messages (such as "Your files + would be overwritten...") to stdout, while the merge backend writes + them to stderr. + +* State directories: The two backends keep their state in different + directories under .git/ include::merge-strategies.txt[] diff --git a/builtin/rebase.c b/builtin/rebase.c index 6154ad8..ffa467a 100644 --- a/builtin/rebase.c +++ b/builtin/rebase.c @@ -44,14 +44,22 @@ static GIT_PATH_FUNC(merge_dir, "rebase-merge") enum rebase_type { REBASE_UNSPECIFIED = -1, - REBASE_AM, + REBASE_APPLY, REBASE_MERGE, - REBASE_INTERACTIVE, REBASE_PRESERVE_MERGES }; +enum empty_type { + EMPTY_UNSPECIFIED = -1, + EMPTY_DROP, + EMPTY_KEEP, + EMPTY_ASK +}; + struct rebase_options { enum rebase_type type; + enum empty_type empty; + const char *default_backend; const char *state_dir; struct commit *upstream; const char *upstream_name; @@ -77,7 +85,6 @@ struct rebase_options { const char *action; int signoff; int allow_rerere_autoupdate; - int keep_empty; int autosquash; char *gpg_sign_opt; int autostash; @@ -92,6 +99,8 @@ struct rebase_options { #define REBASE_OPTIONS_INIT { \ .type = REBASE_UNSPECIFIED, \ + .empty = EMPTY_UNSPECIFIED, \ + .default_backend = "merge", \ .flags = REBASE_NO_QUIET, \ .git_am_opts = ARGV_ARRAY_INIT, \ .git_format_patch_opt = STRBUF_INIT \ @@ -110,6 +119,9 @@ static struct replay_opts get_replay_opts(const struct rebase_options *opts) replay.allow_rerere_auto = opts->allow_rerere_autoupdate; replay.allow_empty = 1; replay.allow_empty_message = opts->allow_empty_message; + replay.drop_redundant_commits = (opts->empty == EMPTY_DROP); + replay.keep_redundant_commits = (opts->empty == EMPTY_KEEP); + replay.quiet = !(opts->flags & REBASE_NO_QUIET); replay.verbose = opts->flags & REBASE_VERBOSE; replay.reschedule_failed_exec = opts->reschedule_failed_exec; replay.gpg_sign = xstrdup_or_null(opts->gpg_sign_opt); @@ -329,8 +341,8 @@ static int do_interactive_rebase(struct rebase_options *opts, unsigned flags) argv_array_pushl(&make_script_args, "", revisions, NULL); if (opts->restrict_revision) - argv_array_push(&make_script_args, - oid_to_hex(&opts->restrict_revision->object.oid)); + argv_array_pushf(&make_script_args, "^%s", + oid_to_hex(&opts->restrict_revision->object.oid)); ret = sequencer_make_script(the_repository, &todo_list.buf, make_script_args.argc, make_script_args.argv, @@ -359,7 +371,7 @@ static int do_interactive_rebase(struct rebase_options *opts, unsigned flags) return ret; } -static int run_rebase_interactive(struct rebase_options *opts, +static int run_sequencer_rebase(struct rebase_options *opts, enum action command) { unsigned flags = 0; @@ -367,7 +379,6 @@ static int run_rebase_interactive(struct rebase_options *opts, git_config_get_bool("rebase.abbreviatecommands", &abbreviate_commands); - flags |= opts->keep_empty ?
