test_description="recursive merge with directory renames"

# includes checking of many corner cases, with a similar methodology to:
|
|
# t6042: corner cases with renames but not criss-cross merges
|
|
# t6036: corner cases with both renames and criss-cross merges
|
|
#
|
|
# The setup for all of them, pictorially, is:
|
|
#
|
|
# A
|
|
# o
|
|
# / \
|
|
# O o ?
|
|
# \ /
|
|
# o
|
|
# B
|
|
#
|
|
# To help make it easier to follow the flow of tests, they have been
|
|
# divided into sections and each test will start with a quick explanation
|
|
# of what commits O, A, and B contain.
|
|
#
|
|
# Notation:
|
|
# z/{b,c} means files z/b and z/c both exist
|
|
# x/d_1 means file x/d exists with content d1. (Purpose of the
|
|
# underscore notation is to differentiate different
|
|
# files that might be renamed into each other's paths.)

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