2015-04-29merge: deprecate 'git merge <message> HEAD <commit>' syntaxLibravatar Junio C Hamano1-1/+1
We had this in "git merge" manual for eternity: 'git merge' <msg> HEAD <commit>... [This] syntax (<msg> `HEAD` <commit>...) is supported for historical reasons. Do not use it from the command line or in new scripts. It is the same as `git merge -m <msg> <commit>...`. With the update to "git merge" to make it understand what is recorded in FETCH_HEAD directly, including Octopus merge cases, we now can rewrite the use of this syntax in "git pull" with a simple "git merge FETCH_HEAD". Also there are quite a few fallouts in the test scripts, and it turns out that "git cvsimport" also uses this old syntax to record a merge. Judging from this result, I would not be surprised if dropping the support of the old syntax broke scripts people have written and been relying on for the past ten years. But at least we can start the deprecation process by throwing a warning message when the syntax is used. With luck, we might be able to drop the support in a few years.

2011-08-14merge-recursive: Fix sorting order and directory change assumptionsLibravatar Elijah Newren1-8/+18
We cannot assume that directory/file conflicts will appear in sorted order; for example, 'letters.txt' comes between 'letters' and 'letters/file'. Thanks to Johannes for a pointer about qsort stability issues with Windows and suggested code change.

2010-10-06test-lib: make test_expect_code a test commandLibravatar Ævar Arnfjörð Bjarmason1-1/+3
Change test_expect_code to be a normal test command instead of a top-level command. As a top-level command it would fail in cases like: test_expect_code 1 'phoney' ' foo && bar && (exit 1) ' Here the test might incorrectly succeed if "foo" or "bar" happened to fail with exit status 1. Instead we now do: test_expect_success 'phoney' ' foo && bar && test_expect_code 1 "(exit 1)" ' Which will only succeed if "foo" and "bar" return status 0, and "(exit 1)" returns status 1. Note that test_expect_code has been made slightly noisier, as it reports the exit code it receives even upon success. Some test code in t0000-basic.sh relied on the old semantics of test_expect_code to test the test_when_finished command. I've converted that code to use an external test similar to the TODO test I added in v1.7.3-rc0~2^2~3.

2010-09-29merge-recursive: Make room for directories in D/F conflictsLibravatar Elijah Newren1-1/+1
When there are unmerged entries present, make sure to check for D/F conflicts first and remove any files present in HEAD that would be in the way of creating files below the correspondingly named directory. Such files will be processed again at the end of the merge in process_df_entry(); at that time we will be able to tell if we need to and can reinstate the file, whether we need to place its contents in a different file due to the directory still being present, etc. Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-09-29handle_delete_modify(): Check whether D/F conflicts are still presentLibravatar Elijah Newren1-1/+1
If all the paths below some directory involved in a D/F conflict were not removed during the rest of the merge, then the contents of the file whose path conflicted needs to be recorded in file with an alternative filename.

2010-07-09merge_recursive: Fix renames across paths below D/F conflictsLibravatar Elijah Newren1-1/+1
The rename logic in process_renames() handles renames and merging of file contents and then marks files as processed. However, there may be higher stage entries left in the index for other reasons (e.g., due to D/F conflicts). By checking for such cases and marking the entry as not processed, it allows process_entry() later to look at it and handle those higher stages.

2009-07-29Add a reminder test case for a merge with F/D transitionLibravatar Alex Riesen1-0/+23
The problem is that if a file was replaced with a directory containing another file with the same content and mode, an attempt to merge it with a branch descended from a commit before this F->D transition will cause merge-recursive to break. It breaks even if there were no conflicting changes on that other branch. Originally reported by Anders Melchiorsen.
