Junio C Hamano	dfc8f39e43	Allow "git-reset path" when unambiguous Resetting a selected set of index entries is done with "git reset -- paths" syntax, but we did not allow -- to be omitted even when the command is unambiguous. This updates the command to follow the general rule: * When -- appears, revs come before it, and paths come after it; * When there is no --, earlier ones are revs and the rest are paths, and we need to guess. When lack of -- marker forces us to guess, we protect from user errors and typoes by making sure what we treat as revs do not appear as filenames in the work tree, and what we treat as paths do appear as filenames in the work tree, and by erroring out if that is not the case. We tell the user to disambiguate by using -- in such a case. which is employed elsewhere in the system. When this rule is applied to "reset", because we can have only zero or one rev to the command, the check can be slightly simpler than other programs. We have to check only the first one or two tokens after the command name and options, and when they are: -- A: no explicit rev given; "A" and whatever follows it are paths. A --: explicit rev "A" given and whatever follows the "--" are paths. A B: "A" could be rev or path and we need to guess. "B" could be missing but if exists that (and everything that follows) would be paths. So we apply the guess only in the last case and only to "A" (not "B" and what comes after it). * As long as "A" is unambiguously a path, index entries for "A", "B" (and everything that follows) are reset to the HEAD revision. * If "A" is unambiguously a rev, on the other hand, the index entries for "B" (and everything that follows) are reset to the "A" revision.

Junio C Hamano	3af828634f	tests: do not use implicit "git diff --no-index" As a general principle, we should not use "git diff" to validate the results of what git command that is being tested has done. We would not know if we are testing the command in question, or locating a bug in the cute hack of "git diff --no-index". Rather use test_cmp for that purpose.

Johannes Schindelin	620a6cd42e	builtin-reset: avoid forking "update-index --refresh" Instead of forking update-index, call refresh_cache() directly. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>	17 years ago
Johannes Schindelin	cdf4a751fa	builtin-reset: do not call "ls-files --unmerged" Since reset is a builtin now, it can use the full power of libgit.a and check for unmerged entries itself.

Johannes Schindelin	2e7a9785c2	git-reset: do not be confused if there is nothing to reset The purpose of the function update_index_from_diff() (which is the callback function we give do_diff_cache()) is to update those index entries which differ from the given commit. Since do_diff_cache() plays games with the in-memory index, this function discarded the cache and reread it. Then, back in the function read_from_tree() we wrote the index. Of course, this broke down when there were no changes and update_index_from_diff() was not called, and therefore the mangled index was not discarded. The solution is to move the index writing into the function update_index_from_diff(). Noticed by Björn Steinbrink.

Carlos Rica	359048d6ec	Add tests for documented features of "git reset". This adds the new file t/t7102-reset.sh following the text and examples in "Documentation/git-reset.txt" in order to check the behaviour of the upcoming "builtin-reset.c", and be able to compare it with the original "git-reset.sh".
