The code introduced in + Git 2.17 timeframe failed to parse such a patch, but now it learned + to notice the situation and cope with it. + (merge f4d35a6b49 pw/add-p-recount later to maint). + + * The code to try seeing if a fetch is necessary in a submodule + during a fetch with --recurse-submodules got confused when the path + to the submodule was changed in the range of commits in the + superproject, sometimes showing "(null)".

The +# final line of a subshell may still break the &&-chain by using ";" internally +# to chain commands together rather than "&&", so "?!SEMI?!" is never removed +# from a line (even though "?!AMP?!" might be). +# +# Care is taken to recognize the last _statement_ of a multi-line subshell, not +# necessarily the last textual _line_ within the subshell, since &&-chaining +# applies to statements, not to lines. Consequently, blank lines, comment +# lines, and here-docs are swallowed (but not the command to which the here-doc +# is attached), leaving the last statement in the "hold" area, not the last +# line, thus simplifying &&-link checking. +# +# The final statement before "done" in for- and while-loops, and before "elif", +# "else", and "fi" in if-then-else likewise must not end with "&&", thus +# receives similar treatment. +# +# Swallowing here-docs with arbitrary tags requires a bit of finesse. When a +# line such as "cat <<EOF >out" is seen, the here-doc tag is moved to the front +# of the line enclosed in angle brackets as a sentinel, giving "<EOF>cat >out". +# As each subsequent line is read, it is appended to the target line and a +# (whitespace-loose) back-reference match /^<(.*)>\n\1$/ is attempted to see if +# the content inside "<...>" matches the entirety of the newly-read line. For +# instance, if the next line read is "some data", when concatenated with the +# target line, it becomes "<EOF>cat >out\nsome data", and a match is attempted +# to see if "EOF" matches "some data".

When a line consisting of only "EOF" (and possible whitespace) is +# encountered, it is appended to the target line giving "<EOF>cat >out\nEOF", +# in which case the "EOF" inside "<...>" does match the text following the +# newline, thus the closing here-doc tag has been found. The closing tag line +# and the "<...>" prefix on the target line are then discarded, leaving just +# the target line "cat >out". +# +# To facilitate regression testing (and manual debugging), a ">" annotation is +# applied to the line containing ")" which closes a subshell, ">>" to a line +# closing a nested subshell, and ">>>" to a line closing both at once.

Bad. +# 4: Keep neither file: Merging D1 & E1 reports the D/F add/add conflict. # -# Merging D & E1 requires we first create a virtual merge base X from -# merging A & B in memory. Now, if X could keep both 'a' and 'a/file' in -# the index, then the merge of D & E1 could be resolved cleanly with both -# 'a' and 'a/file' removed. Since git does not currently allow creating -# such a tree, the best we can do is have X contain both 'a~<unique>' and -# 'a/file' resulting in the merge of D and E1 having a rename/delete -# conflict for 'a'. (Although this merge appears to be unsolvable with git -# currently, git could do a lot better than it currently does with these -# d/f conflicts, which is the purpose of this test.) +# So 4 sounds good for this case, but if we were to merge D1 & E3, where E3 +# is defined as: +# Commit E3: Merge B & C, keeping modified a, and deleting a/ +# then we'd get an add/add conflict for 'a', which seems suboptimal. A little +# creativity leads us to an alternate choice: +# 5: Keep 'a' as 'a~$UNIQUE' and a/file; results: +# Merge D1 & E1: rename/delete conflict for 'a'; a/file silently deleted +# Merge D1 & E3 is clean, as expected. # -# Merge of D & E2 has similar issues for path 'a', but should always result -# in a modify/delete conflict for path 'a/file'. +# So choice 5 at least provides some kind of conflict for the original case, +# and can merge cleanly as expected with D1 and E3. It also made things just +# slightly funny for merging D1 and e$, where E4 is defined as: +# Commit E4: Merge B & C, modifying 'a' and renaming to 'a2', and deleting 'a/' +# in this case, we'll get a rename/rename(1to2) conflict because a~$UNIQUE +# gets renamed to 'a' in D1 and to 'a2' in E4. But that's better than having +# two files (both 'a' and 'a2') sitting around without the user being notified +# that we could detect they were related and need to be merged. Also, choice +# 5 makes the handling of 'a/file' seem suboptimal. What if we were to merge +# D2 and E4, where D2 is: +# Commit D2: Merge B & C, renaming 'a'->'a2', keeping 'a/file' +# This would result in a clean merge with 'a2' having three-way merged +# contents (good), and deleting 'a/' (bad) -- it doesn't detect the +# conflict in how the different sides treated a/file differently. +# Continuing down the creative route: +# 6: Keep 'a' as 'a~$UNIQUE1' and keep 'a/' as 'a~$UNIQUE2/'; results: +# Merge D1 & E1: rename/delete conflict for 'a' and each path under 'a/'. +# Merge D1 & E3: clean, as expected. +# Merge D1 & E4: rename/rename(1to2) conflict on 'a' vs 'a2'. +# Merge D2 & E4: clean for 'a2', rename/delete for a/file # -# We run each merge in both directions, to check for directional issues -# with D/F conflict handling. +# Choice 6 could cause rename detection to take longer (providing more targets +# that need to be searched). Also, the conflict message for each path under +# 'a/' might be annoying unless we can detect it at the directory level, print +# it once, and then suppress it for individual filepaths underneath. +# +# +# As of time of writing, git uses choice 5. Directory rename detection and +# rename detection performance improvements might make choice 6 a desirable +# improvement. But we can at least document where we fall short for now... +# +# +# Historically, this testcase also used: +# Commit E2: Merge B & C, deleting 'a' but keeping slightly modified 'a/file' +# The merge of D1 & E2 is very similar to D1 & E1 -- it has similar issues for +# path 'a', but should always result in a modify/delete conflict for path +# 'a/file'.

Later we added +# D1 & E3 +# D1 & E4 +# D2 & E4 +# for good measure, though we only ran those one way because we had pretty +# good confidence in merge-recursive's directional handling of D/F issues. +# +# Just to summarize all the intermediate merge commits: +# Commit D1: Merge B & C, keeping a and deleting a/ +# Commit D2: Merge B & C, renaming a->a2, keeping a/file +# Commit E1: Merge B & C, deleting a but keeping a/file +# Commit E2: Merge B & C, deleting a but keeping slightly modified a/file +# Commit E3: Merge B & C, keeping modified a, and deleting a/ +# Commit E4: Merge B & C, modifying 'a' and renaming to 'a2', and deleting 'a/' # test_expect_success 'setup differently handled merges of directory/file conflict' ' -
