From 47c8c5a99d61fb0137ec7d31d5e3f2086d7c449f Mon Sep 17 00:00:00 2001 From: Paul-Sebastian Ungureanu Date: Thu, 20 Dec 2018 21:44:17 +0200 Subject: [PATCH 01/30] sha1-name.c: add `get_oidf()` which acts like `get_oid()` Compared to `get_oid()`, `get_oidf()` has as parameters a pointer to `object_id`, a printf format string and additional arguments.

Converting all at once proved hard to review, so starting with just apply lets conversion get started without the other commands being finished. The helper is being implemented as a drop in replacement for stash so that when it is complete it can simply be renamed and the shell script deleted. Delete the contents of the apply_stash shell function and replace it with a call to stash--helper apply until pop is also converted.

For example, `git stash push -u` would call at some points the following functions: * `check_changes()` (inside `do_push_stash()`) * `do_create_stash()`, which calls: `check_changes()` and `get_untracked_files()` Note that `check_changes()` also calls `get_untracked_files()`. So, `check_changes()` is called 2 times and `get_untracked_files()` 3 times. The old function `check_changes()` now consists of two functions: `get_untracked_files()` and `check_changes_tracked_files()`. These are the call chains for `push` and `create`: * `push_stash()` -> `do_push_stash()` -> `do_create_stash()` * `create_stash()` -> `do_create_stash()` To prevent calling the same functions over and over again, `check_changes()` inside `do_create_stash()` is now placed in the caller functions (`create_stash()` and `do_push_stash()`). This way `check_changes()` and `get_untracked files()` are called only one time. https://public-inbox.org/git/20180818223329.GJ11326@hank.intra.tgummerer.com/ Signed-off-by: Paul-Sebastian Ungureanu Signed-off-by: Junio C Hamano --- builtin/stash--helper.c | 55 +++++++++++++++++++++++------------------ 1 file changed, 31 insertions(+), 24 deletions(-) diff --git a/builtin/stash--helper.c b/builtin/stash--helper.c index dc4ed52c96..d3c7748fd9 100644 --- a/builtin/stash--helper.c +++ b/builtin/stash--helper.c @@ -886,18 +886,18 @@ static int get_untracked_files(struct pathspec ps, int include_untracked, } /* - * The return value of `check_changes()` can be: + * The return value of `check_changes_tracked_files()` can be: * * < 0 if there was an error * = 0 if there are no changes. * > 0 if there are changes. */ -static int check_changes(struct pathspec ps, int include_untracked) + +static int check_changes_tracked_files(struct pathspec ps) { int result; struct rev_info rev; struct object_id dummy; - struct strbuf out = STRBUF_INIT; /* No initial commit. */ if (get_oid("HEAD", &dummy)) @@ -925,16 +925,28 @@ static int check_changes(struct pathspec ps, int include_untracked) if (diff_result_code(&rev.diffopt, result)) return 1; - if (include_untracked && get_untracked_files(ps, include_untracked, - &out)) { - strbuf_release(&out); - return 1; - } - - strbuf_release(&out); return 0; } +/* + * The function will fill `untracked_files` with the names of untracked files + * It will return 1 if there were any changes and 0 if there were not. + */ + +static int check_changes(struct pathspec ps, int include_untracked, + struct strbuf *untracked_files) +{ + int ret = 0; + if (check_changes_tracked_files(ps)) + ret = 1; + + if (include_untracked && get_untracked_files(ps, include_untracked, + untracked_files)) + ret = 1; + + return ret; +} + static int save_untracked_files(struct stash_info *info, struct strbuf *msg, struct strbuf files) { @@ -1143,7 +1155,7 @@ static int do_create_stash(struct pathspec ps, struct strbuf *stash_msg_buf, head_commit = lookup_commit(the_repository, &info->b_commit); } - if (!check_changes(ps, include_untracked)) { + if (!check_changes(ps, include_untracked, &untracked_files)) { ret = 1; goto done; } @@ -1168,8 +1180,7 @@ static int do_create_stash(struct pathspec ps, struct strbuf *stash_msg_buf, goto done; } - if (include_untracked && get_untracked_files(ps, include_untracked, - &untracked_files)) { + if (include_untracked) { if (save_untracked_files(info, &msg, untracked_files)) { if (!quiet) fprintf_ln(stderr, _("Cannot save " @@ -1254,20 +1265,15 @@ static int create_stash(int argc, const char **argv, const char *prefix) 0); memset(&ps, 0, sizeof(ps)); - strbuf_addstr(&stash_msg_buf, stash_msg); - ret = do_create_stash(ps, &stash_msg_buf, include_untracked, 0, &info, - NULL, 0); + if (!check_changes_tracked_files(ps)) + return 0; - if (!ret) + strbuf_addstr(&stash_msg_buf, stash_msg); + if (!(ret = do_create_stash(ps, &stash_msg_buf, 0, 0, &info, NULL, 0))) printf_ln("%s", oid_to_hex(&info.w_commit)); strbuf_release(&stash_msg_buf); - - /* - * ret can be 1 if there were no changes.

In order to do that, `create` and `push` were adapted to work without `stash.sh`. For example, before this commit, `git stash create` called `git stash--helper create --message "$*"`. If it called `git stash--helper create "$@"`, then some of these changes wouldn't have been necessary. This commit also removes the word `helper` since now stash is called directly and not by a shell script.

Let's end users a way out when they discover a bug in the builtin command: `stash.useBuiltin`. As the file name `git-stash` is already in use, let's rename the scripted backend to `git-legacy-stash`. To make the test suite pass with `stash.useBuiltin=false`, this commit also backports rudimentary support for `-q` (but only *just* enough to appease the test suite), and adds a super-ugly hack to force exit code 129 for `git stash -h`.

This is needed to spot that we're not introducing any regressions in the legacy stash version while we're carrying both it and the new built-in version. This imitates the equivalent treatment for the built-in rebase in 62c23938fae5 (tests: add a special setup where rebase.useBuiltin is off, 2018-11-14).

A state for which the built-in stash was not prepared, as it failed to initialize the `rev` structure in that case before using `&rev.pending`. If `reset_tree()` returns a non-zero value, `stash_working_tree()` calls `object_array_clear()` with `&rev.pending`. If `rev` is not initialized, this causes a segmentation fault. Prevent this by initializing `rev` before calling `reset_tree()`. This fixes https://github.com/git-for-windows/git/issues/2006.
