Jeff King	814f7d902b	t3030: fix accidental success in symlink rename In this test, we have merge two branches. On one branch, we renamed "a" to "e". On the other, we renamed "a" to "e" and then added a symlink pointing at "a" pointing to "e". The results for the test indicate that the merge should succeed, but also that "a" should no longer exist. Since both sides renamed "a" to the same destination, we will end up comparing those destinations for content. But what about what's left? One side (the rename only), replaced "a" with nothing. The other side replaced it with a symlink. The common base must also be nothing, because any "a" before this was meaningless (it was totally unrelated content that ended up getting renamed). The only sensible resolution is to keep the symlink. The rename-only side didn't touch the content versus the common base, and the other side added content. The 3-way merge dictates that we take the side with a change. And this gives the overall merge an intuitive result. One side made one change (a rename), and the other side made two changes: an identical rename, and an addition (that just happened to be at the same spot). The end result should contain both changes.

Jonathan Nieder	a48fcd8369	tests: add missing && Breaks in a test assertion's && chain can potentially hide failures from earlier commands in the chain. Commands intended to fail should be marked with !, test_must_fail, or test_might_fail. The examples in this patch do not require that.

Schalk, Ken	8a1c0d322e	t3030: Add a testcase for resolvable rename/add conflict with symlinks `d5af510` (RE: [PATCH] Avoid rename/add conflict when contents are identical 2010-09-01) avoided erroring out in a rename/add conflict when the contents were identical. A simpler fix could have handled that particular testcase, but it would not correctly handle the case where a symlink is involved. Add another testcase using symlinks, to avoid breaking that case.

Schalk, Ken	d5af51053c	RE: [PATCH] Avoid rename/add conflict when contents are identical >Due to this this (and maybe all the tests) need to depend on the >SYMLINKS prereq. Here's a third attempt with no use of symlinks in the test: Skip the entire rename/add conflict case if the file added on the other branch has the same contents as the file being renamed. This avoids giving the user an extra copy of the same file and presenting a conflict that is confusing and pointless. A simple test of this case has been added in t/t3030-merge-recursive.sh.

Matthieu Moy	e6c111b4c0	unpack_trees: group error messages by type When an error is encountered, it calls add_rejected_file() which either - directly displays the error message and stops if in plumbing mode (i.e. if show_all_errors is not initialized at 1) - or stores it so that it will be displayed at the end with display_error_msgs(), Storing the files by error type permits to have a list of files for which there is the same error instead of having a serie of almost identical errors. As each bind_overlap error combines a file and an old file, a list cannot be done, therefore, theses errors are not stored but directly displayed.

Johannes Sixt	7d82b06d2b	merge-recursive: demonstrate an incorrect conflict with submodule When one side of a merge turns a directory into a submodule, and the other side does not touch that directory (but has other non-conflicting changes), then a merge should succeed. But currently, it does not; it rather fails with a file/directory conflict. Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>	15 years ago
Matthieu Moy	d38a30df7d	Be more user-friendly when refusing to do something because of conflict. Various commands refuse to run in the presence of conflicts (commit, merge, pull, cherry-pick/revert). They all used to provide rough, and inconsistant error messages. A new variable advice.resolveconflict is introduced, and allows more verbose messages, pointing the user to the appropriate solution. For commit, the error message used to look like this: $ git commit foo.txt: needs merge foo.txt: unmerged (c34a92682e0394bc0d6f4d4a67a8e2d32395c169) foo.txt: unmerged (3afcd75de8de0bb5076942fcb17446be50451030) foo.txt: unmerged (c9785d77b76dfe4fb038bf927ee518f6ae45ede4) error: Error building trees The "need merge" line is given by refresh_cache. We add the IN_PORCELAIN option to make the output more consistant with the other porcelain commands, and catch the error in return, to stop with a clean error message. The next lines were displayed by a call to cache_tree_update(), which is not reached anymore if we noticed the conflict. The new output looks like: U foo.txt fatal: 'commit' is not possible because you have unmerged files. Please, fix them up in the work tree, and then use 'git add/rm <file>' as appropriate to mark resolution and make a commit, or use 'git commit -a'. Pull is slightly modified to abort immediately if $GIT_DIR/MERGE_HEAD exists instead of waiting for merge to complain. The behavior of merge and the test-case are slightly modified to reflect the usual flow: start with conflicts, fix them, and afterwards get rid of MERGE_HEAD, with different error messages at each stage.

Clemens Buchacher	c8c562a238	refuse to merge during a merge The following is an easy mistake to make for users coming from version control systems with an "update and commit"-style workflow. 1. git pull 2. resolve conflicts 3. git pull Step 3 overrides MERGE_HEAD, starting a new merge with dirty index. IOW, probably not what the user intended. Instead, refuse to merge again if a merge is in progress.

Junio C Hamano	446247db78	merge: fix numerus bugs around "trivial merge" area The "trivial merge" codepath wants to optimize itself by making an internal call to the read-tree machinery, but it does not read the index before doing so, and the codepath is never exercised. Incidentally, this failure to read the index upfront means that the safety to refuse doing anything when the index is unmerged does not kick in, either. These two problem are fixed by using read_cache_unmerged() that does read the index before checking if it is unmerged at the beginning of cmd_merge(). The primary logic of the merge, however, assumes that the process never reads the index in-core, and the call to write_cache_as_tree() it makes from write_tree_trivial() will always read from the on-disk index that is prepared the strategy back-ends. This assumption is now broken by the above fix. To fix this issue, we now call discard_cache() before calling write_tree_trivial() when it wants to write the on-disk index as a tree. When multiple strategies are tried, their results are evaluated by reading the resulting index and inspecting it. The codepath needs to make a call to read_cache() for each successful strategy, and for that to work, they need to discard_cache() the one read by the previous round. Also the "trivial merge" forgot that the current commit is one of the parents of the resulting commit. Signed-off-by: Junio C Hamano <gitster@pobox.com>	17 years ago
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.

Junio C Hamano	885b981075	t3030: merge-recursive backend test. We have fairly extensive coverage of read-tree 3-way machinery, and many Porcelain-ish tests use git-merge front-end tests, but we did not have good basic test for merge-recursive, which made it very hard to hack on it. I used this during the recent work to teach D/F conflicts to merge-recursive. Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
