2017-11-27Merge branch 'sb/test-cherry-pick-submodule-getting-in-a-way'Junio C Hamano
The three-way merge performed by "git cherry-pick" was confused when a new submodule was added in the meantime, which has been fixed (or "papered over"). * sb/test-cherry-pick-submodule-getting-in-a-way: merge-recursive: handle addition of submodule on our side of history t/3512: demonstrate unrelated submodule/file conflict as cherry-pick failure

2017-11-15merge-recursive: handle addition of submodule on our side of historyElijah Newren
The code for a newly added path assumed that the path was a normal file, and thus checked for there being a directory still being in the way of the file. Note that since unpack_trees() does path-in-the-way checks already, the only way for there to be a directory in the way at this point in the code, is if there is some kind of D/F conflict in the merge. For a submodule addition on HEAD's side of history, the submodule would have already been present. This means that we do expect there to be a directory present but should not consider it to be "in the way"; instead, it's the expected submodule. So, when there's a submodule addition from HEAD's side, don't bother checking the working copy for a directory in the way.

A new option --ignore-cr-at-eol tells the diff machinery to treat a carriage-return at the end of a (complete) line as if it does not exist. Just like other "--ignore-*" options to ignore various kinds of whitespace differences, this will help reviewing the real changes you made without getting distracted by spurious CRLF<->LF conversion made by your editor program.

2017-09-08merge-recursive: change current file dir string_lists to hashmapKevin Willford
The code was using two string_lists, one for the directories and one for the files. The code never checks the lists independently so we should be able to only use one list. The string_list also is a O(log n) for lookup and insertion. Switching this to use a hashmap will give O(1) which will save some time when there are millions of paths that will be checked.

2017-09-06merge-recursive: remove return value from get_files_dirsKevin Willford
The return value of the get_files_dirs call is never being used. Looking at the history of the file and it was originally only being used for debug output statements. Also when read_tree_recursive return value is non zero it is changed to zero. This leads me to believe that it doesn't matter if read_tree_recursive gets an error. Since the debug output has been removed and the caller isn't checking the return value there is no reason to keep calculating and returning a value.

2017-01-30merge-recursive: make "CONFLICT (rename/delete)" message show both pathsMatt McCutchen
The current message printed by "git merge-recursive" for a rename/delete conflict is like this: CONFLICT (rename/delete): new-path deleted in HEAD and renamed in other-branch. Version other-branch of new-path left in tree. To be more helpful, the message should show both paths of the rename and state that the deletion occurred at the old path, not the new path. So change the message to the following format: CONFLICT (rename/delete): old-path deleted in HEAD and renamed to new-path in other-branch. Version other-branch of new-path left in tree. Since this doubles the number of cases in handle_change_delete (modify vs. rename), refactor the code to halve the number of cases again by merging the cases where o->branch1 has the change and o->branch2 has the delete with the cases that are the other way around. Also add a simple test of the new conflict message. Signed-off-by: Matt McCutchen <matt@mattmccutchen.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-12-07hold_locked_index(): align error handling with hold_lockfile_for_update()Junio C Hamano
Callers of the hold_locked_index() function pass 0 when they want to prepare to write a new version of the index file without wishing to die or emit an error message when the request fails (e.g. somebody else already held the lock), and pass 1 when they want the call to die upon failure. This option is called LOCK_DIE_ON_ERROR by the underlying lockfile API, and the hold_locked_index() function translates the paramter to LOCK_DIE_ON_ERROR when calling the hold_lock_file_for_update(). Replace these hardcoded '1' with LOCK_DIE_ON_ERROR and stop translating. Callers other than the ones that are replaced with this change pass '0' to the function; no behaviour change is intended with this patch. Signed-off-by: Junio C Hamano <gitster@pobox.com> --- Among the callers of hold_locked_index() that passes 0: - diff.c::refresh_index_quietly() at the end of "git diff" is an opportunistic update; it leaks the lockfile structure but it is just before the program exits and nobody should care. - builtin/describe.c::cmd_describe(), builtin/commit.c::cmd_status(), sequencer.c::read_and_refresh_cache() are all opportunistic updates and they are OK. - builtin/update-index.c::cmd_update_index() takes a lock upfront but we may end up not needing to update the index (i.e. the entries may be fully up-to-date), in which case we do not need to issue an error upon failure to acquire the lock. We do diagnose and die if we indeed need to update, so it is OK. - wt-status.c::require_clean_work_tree() IS BUGGY. It asks silence, does not check the returned value. Compare with callsites like cmd_describe() and cmd_status() to notice that it is wrong to call update_index_if_able() unconditionally.
2016-11-28merge-recursive.c: use string_list_sort instead of qsortNguyễn Thái Ngọc Duy
Merge-recursive sorts a string list using a raw qsort(), where it feeds the "items" from one struct but the "nr" and size fields from another struct. This isn't a bug because one list is a copy of the other, but it's unnecessarily confusing (and also caused our recent QSORT() cleanups via coccinelle to miss this call site). Let's use string_list_sort() instead, which is more concise and harder to get wrong. Note that we need to adjust our comparison function, which gets fed only the strings now, not the string_list_items. That's OK because we don't use the "util" field as part of our sort.

2016-11-18submodules: allow empty working-tree dirs in merge/cherry-pickDavid Turner
When a submodule is being merged or cherry-picked into a working tree that already contains a corresponding empty directory, do not record a conflict. One situation where this bug appears is: - Commit 1 adds a submodule - Commit 2 removes that submodule and re-adds it into a subdirectory (sub1 to sub1/sub1). - Commit 3 adds an unrelated file. Now the user checks out commit 1 (first deinitializing the submodule), and attempts to cherry-pick commit 3. Previously, this would fail, because the incoming submodule sub1/sub1 would falsely conflict with the empty sub1 directory. This patch ignores the empty sub1 directory, fixing the bug. We only ignore the empty directory if the object being emplaced is a submodule, which expects an empty directory.

One of the indirect callers of make_virtual_commit() passes the result of oid_to_hex() as the name, i.e. a pointer to a static buffer. Since the function uses that string pointer directly in building a struct merge_remote_desc, multiple entries can end up sharing the same name inadvertently.

2016-08-01merge-recursive: flush output buffer even when erroring outJohannes Schindelin
Ever since 66a155b (Enable output buffering in merge-recursive., 2007-01-14), we had a problem: When the merge failed in a fatal way, all regular output was swallowed because we called die() and did not get a chance to drain the output buffers. To fix this, several modifications were necessary: - we needed to stop die()ing, to give callers a chance to do something when an error occurred (in this case, flush the output buffers), - we needed to delay printing the error message so that the caller can print the buffered output before that, and - we needed to make sure that the output buffers are flushed even when the return value indicates an error. The first two changes were introduced through earlier commits in this patch series, and this commit addresses the third one.
