3 | test_description="recursive merge with directory renames" | |
4 | # includes checking of many corner cases, with a similar methodology to: | |
5 | # t6042: corner cases with renames but not criss-cross merges | |
6 | # t6036: corner cases with both renames and criss-cross merges | |
7 | # | |
8 | # The setup for all of them, pictorially, is: | |
9 | # | |
10 | # A | |
11 | # o | |
12 | # / \ | |
13 | # O o ? | |
14 | # \ / | |
15 | # o | |
16 | # B | |
17 | # | |
18 | # To help make it easier to follow the flow of tests, they have been | |
19 | # divided into sections and each test will start with a quick explanation | |
20 | # of what commits O, A, and B contain. | |
21 | # | |
22 | # Notation: | |
23 | # z/{b,c} means files z/b and z/c both exist | |
24 | # x/d_1 means file x/d exists with content d1. (Purpose of the | |
25 | # underscore notation is to differentiate different | |
26 | # files that might be renamed into each other's paths.) | |

742 | # SECTION 4: Partially renamed directory; still exists on both sides of merge | |
743 | # | |
744 | # What if we were to attempt to do directory rename detection when someone | |
745 | # "mostly" moved a directory but still left some files around, or, | |
746 | # equivalently, fully renamed a directory in one commmit and then recreated | |
747 | # that directory in a later commit adding some new files and then tried to | |
748 | # merge? | |
749 | # | |
750 | # It's hard to divine user intent in these cases, because you can make an | |
751 | # argument that, depending on the intermediate history of the side being | |
752 | # merged, that some users will want files in that directory to | |
753 | # automatically be detected and renamed, while users with a different | |
754 | # intermediate history wouldn't want that rename to happen. | |
755 | # | |
756 | # I think that it is best to simply not have directory rename detection | |
757 | # apply to such cases. My reasoning for this is four-fold: (1) it's | |
758 | # easiest for users in general to figure out what happened if we don't | |
759 | # apply directory rename detection in any such case, (2) it's an easy rule | |
760 | # to explain ["We don't do directory rename detection if the directory | |
761 | # still exists on both sides of the merge"], (3) we can get some hairy | |
762 | # edge/corner cases that would be really confusing and possibly not even | |
763 | # representable in the index if we were to even try, and [related to 3] (4) | |
764 | # attempting to resolve this issue of divining user intent by examining | |
765 | # intermediate history goes against the spirit of three-way merges and is a | |
766 | # path towards crazy corner cases that are far more complex than what we're | |
767 | # already dealing with. | |
768 | # | |
769 | # Note that the wording of the rule ("We don't do directory rename | |
770 | # detection if the directory still exists on both sides of the merge.") | |
771 | # also excludes "renaming" of a directory into a subdirectory of itself | |
772 | # (e.g. /some/dir/* -> /some/dir/subdir/*). It may be possible to carve | |
773 | # out an exception for "renaming"-beneath-itself cases without opening | |
774 | # weird edge/corner cases for other partial directory renames, but for now | |
775 | # we are keeping the rule simple. | |

777 | # This section contains a test for a partially-renamed-directory case. | |

1523 | # SECTION 7: More involved Edge/Corner cases | |
1524 | # | |
1525 | # The ruleset we have generated in the above sections seems to provide | |
1526 | # well-defined merges. But can we find edge/corner cases that either (a) | |
1527 | # are harder for users to understand, or (b) have a resolution that is | |
1528 | # non-intuitive or suboptimal? | |
1529 | # | |
1530 | # The testcases in this section dive into cases that I've tried to craft in | |
1531 | # a way to find some that might be surprising to users or difficult for | |
1532 | # them to understand (the next section will look at non-intuitive or | |
1533 | # suboptimal merge results). Some of the testcases are similar to ones | |
1534 | # from past sections, but have been simplified to try to highlight error | |
1535 | # messages using a "modified" path (due to the directory rename). Are | |
1536 | # users okay with these? | |
1537 | # | |
1538 | # In my opinion, testcases that are difficult to understand from this | |
1539 | # section is due to difficulty in the testcase rather than the directory | |
1540 | # renaming (similar to how t6042 and t6036 have difficult resolutions due | |
1541 | # to the problem setup itself being complex). And I don't think the | |
1542 | # error messages are a problem. | |
1543 | # | |
1544 | # On the other hand, the testcases in section 8 worry me slightly more... | |

1843 | # to y/, so maybe everything should move not from x/ to z/, but | |
1844 | # from x/ to z/ to y/. Doing so might make sense from the logic so | |

1918 | # SECTION 8: Suboptimal merges | |
1919 | # | |
1920 | # As alluded to in the last section, the ruleset we have built up for | |
1921 | # detecting directory renames unfortunately has some special cases where it | |
1922 | # results in slightly suboptimal or non-intuitive behavior. This section | |
1923 | # explores these cases. | |
1924 | # | |
1925 | # To be fair, we already had non-intuitive or suboptimal behavior for most | |
1926 | # of these cases in git before introducing implicit directory rename | |
1927 | # detection, but it'd be nice if there was a modified ruleset out there | |
1928 | # that handled these cases a bit better. | |

2177 | # delete) are both coming from commit A, which is illogical. Conflicts | |

2480 | # NOTE: x/f and x/g may be slightly confusing here. The rename from w/f to | |
2481 | # x/f is clear. Let's look beyond that. Here's the logic: | |
2482 | # Commit B renamed x/ -> z/ | |
2483 | # Commit A renamed z/ -> y/ | |
2484 | # So, we could possibly further rename x/f to z/f to y/f, a doubly | |
2485 | # transient rename. However, where does it end? We can chain these | |
2486 | # indefinitely (see testcase 9d). What if there is a D/F conflict | |
2487 | # at z/f/ or y/f/? Or just another file conflict at one of those | |
2488 | # paths? In the case of an N-long chain of transient renamings, | |
2489 | # where do we "abort" the rename at? Can the user make sense of | |
2490 | # the resulting conflict and resolve it? | |
2491 | # | |
2492 | # To avoid this confusion I use the simple rule that if the other side | |
2493 | # of history did a directory rename to a path that your side renamed | |
2494 | # away, then ignore that particular rename from the other side of | |
2495 | # history for any implicit directory renames. | |

3313 | # SECTION 11: Handling dirty (not up-to-date) files | |
3314 | # | |
3315 | # unpack_trees(), upon which the recursive merge algorithm is based, aborts | |
3316 | # the operation if untracked or dirty files would be deleted or overwritten | |
3317 | # by the merge. Unfortunately, unpack_trees() does not understand renames, | |
3318 | # and if it doesn't abort, then it muddies up the working directory before | |
3319 | # we even get to the point of detecting renames, so we need some special | |
3320 | # handling. This was true even of normal renames, but there are additional | |
3321 | # codepaths that need special handling with directory renames. Add | |
3322 | # testcases for both renamed-by-directory-rename-detection and standard | |
3323 | # rename cases. | |
