2018-02-27merge-recursive: ensure we write updates for directory-renamed fileElijah Newren1-3/+1
When a file is present in HEAD before the merge and the other side of the merge does not modify that file, we try to avoid re-writing the file and making it stat-dirty. However, when a file is present in HEAD before the merge and was in a directory that was renamed by the other side of the merge, we have to move the file to a new location and re-write it. Update the code that checks whether we can skip the update to also work in the presence of directory renames.

2018-02-27merge-recursive: avoid spurious rename/rename conflict from dir renamesElijah Newren1-2/+2
If a file on one side of history was renamed, and merely modified on the other side, then applying a directory rename to the modified side gives us a rename/rename(1to2) conflict. We should only apply directory renames to pairs representing either adds or renames. Making this change means that a directory rename testcase that was previously reported as a rename/delete conflict will now be reported as a modify/delete conflict.

2018-02-14merge-recursive: when comparing files, don't include treesElijah Newren1-6/+21
get_renames() would look up stage data that already existed (populated in get_unmerged(), taken from whatever unpack_trees() created), and if it didn't exist, would call insert_stage_data() to create the necessary entry for the given file. The insert_stage_data() fallback becomes much more important for directory rename detection, because that creates a mechanism to have a file in the resulting merge that didn't exist on either side of history. However, insert_stage_data(), due to calling get_tree_entry() loaded up trees as readily as files. We aren't interested in comparing trees to files; the D/F conflict handling is done elsewhere. This code is just concerned with what entries existed for a given path on the different sides of the merge, so create a get_tree_entry_if_blob() helper function and use it.

This populates a set of directory renames for us. The set of directory renames is not yet used, but will be in subsequent commits. Note that the use of a string_list for possible_new_dirs in the new dir_rename_entry struct implies an O(n^2) algorithm; however, in practice I expect the number of distinct directories that files were renamed into from a single original directory to be O(1).

2018-02-14merge-recursive: introduce new functions to handle rename logicElijah Newren1-10/+33
The amount of logic in merge_trees() relative to renames was just a few lines, but split it out into new handle_renames() and cleanup_renames() functions to prepare for additional logic to be added to each. No code or logic changes, just a new place to put stuff for when the rename detection gains additional checks. Note that process_renames() records pointers to various information (such as diff_filepairs) into rename_conflict_info structs. Even though the rename string_lists are not directly used once handle_renames() completes, we should not immediately free the lists at the end of that function because they store the information referenced in the rename_conflict_info, which is used later in process_entry().

2018-01-19merge-recursive: fix logic ordering issueElijah Newren1-1/+1
merge_trees() did a variety of work, including: * Calling get_unmerged() to get unmerged entries * Calling record_df_conflict_files() with all unmerged entries to do some work to ensure we could handle D/F conflicts correctly * Calling get_renames() to check for renames. An easily overlooked issue is that get_renames() can create more unmerged entries and add them to the list, which have the possibility of being involved in D/F conflicts. So the call to record_df_conflict_files() should really be moved after all the rename detection. I didn't come up with any testcases demonstrating any bugs with the old ordering, but I suspect there were some for both normal renames and for directory renames. Fix the ordering.

2018-01-09merge-recursive: do not look at the index during recursive mergeJunio C Hamano1-1/+1
When merging another branch into ours, if their tree is the same as the common ancestor's, we can declare that our tree represents the result of three-way merge. In such a case, the recursive merge backend incorrectly used to create a commit out of our index, even when the index has changes. A recent fix attempted to prevent this by adding a comparison between "our" tree and the index, but forgot that this check must be restricted only to the outermost merge. Inner merges performed by the recursive backend across merge bases are by definition made from scratch without having any local changes added to the index. The call to index_has_changes() during an inner merge is working on the index that has no relation to the merge being performed, preventing legitimate merges from getting carried out. Fix it by limiting the check to the outermost merge. Signed-off-by: Junio C Hamano <gitster@pobox.com>

builtin/merge.c contains this important requirement for merge strategies: /* * At this point, we need a real merge.

However, merge_trees() has a special check for the merge branch exactly matching the merge base; when it detects that situation, it returns early without calling unpack_trees(), because it knows that the HEAD commit already has the correct result. Unfortunately, it didn't check that the index matched HEAD, so after it returned, the outer logic ended up creating a merge commit that included something other than HEAD.

2017-11-27merge-recursive: ignore_case shouldn't reject intentional removalsElijah Newren1-1/+1
In commit ae352c7f3 (merge-recursive.c: fix case-changing merge bug, 2014-05-01), it was observed that removing files could be problematic on case insensitive file systems, because we could end up removing files that differed in case only rather than deleting the intended file -- something that happened when files were renamed on one branch in a way that differed only in case. To avoid that problem, that commit added logic to avoid removing files other than the one intended, rejecting the removal if the files differed only in case. Unfortunately, the logic it used didn't fully implement that condition as stated above; instead it merely checked that a case-insensitive lookup of the file that was requested resulted in finding a file in the index at stage 0, not that the file found in the index actually differed in case. Alternatively, one could view the implementation as making an implicit assumption that the file we actually wanted to remove would never appear in the index with a stage of 0, and thus that if we found a file with our lookup, that it had to be a different file (but different in case only). The net result of this implementation is that it can ignore more requests than it should, leaving a file around in the working copy that should have been removed. Make sure that the file found in the index actually differs in case before silently ignoring the request to remove the file.

2017-11-15merge-recursive: handle addition of submodule on our side of historyElijah Newren1-2/+3
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.

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.

2017-09-06merge-recursive: fix memory leakKevin Willford1-3/+9
In merge_trees if process_renames or process_entry returns less than zero, the method will just return and not free re_merge, re_head, or entries. This change cleans up the allocated variables before returning to the caller. Signed-off-by: Kevin Willford <kewillf@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-08-23treewide: correct several "up-to-date" to "up to date"Martin Ågren1-1/+1
Follow the Oxford style, which says to use "up-to-date" before the noun, but "up to date" after it. Don't change plumbing (specifically send-pack.c, but transport.c (git push) also has the same string). This was produced by grepping for "up-to-date" and "up to date". It turned out we only had to edit in one direction, removing the hyphens. Fix a typo in Documentation/git-diff-index.txt while we're there.
