GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main
tests: mark tests relying on the current default for `init.defaultBranch` In addition to the manual adjustment to let the `linux-gcc` CI job run the test suite with `master` and then with `main`, this patch makes sure that GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME is set in all test scripts that currently rely on the initial branch name being `master by default. To determine which test scripts to mark up, the first step was to force-set the default branch name to `master` in - all test scripts that contain the keyword `master`, - t4211, which expects `t/t4211/history.export` with a hard-coded ref to initialize the default branch, - t5560 because it sources `t/t556x_common` which uses `master`, - t8002 and t8012 because both source `t/annotate-tests.sh` which also uses `master`) This trick was performed by this command: $ sed -i '/^ *\. \.\/\(test-lib\|lib-\(bash\|cvs\|git-svn\)\|gitweb-lib\)\.sh$/i\ GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\ export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\ ' $(git grep -l master t/t[0-9]*.sh) \ t/t4211*.sh t/t5560*.sh t/t8002*.sh t/t8012*.sh After that, careful, manual inspection revealed that some of the test scripts containing the needle `master` do not actually rely on a specific default branch name: either they mention `master` only in a comment, or they initialize that branch specificially, or they do not actually refer to the current default branch. Therefore, the aforementioned modification was undone in those test scripts thusly: $ git checkout HEAD -- \ t/t0027-auto-crlf.sh t/t0060-path-utils.sh \ t/t1011-read-tree-sparse-checkout.sh \ t/t1305-config-include.sh t/t1309-early-config.sh \ t/t1402-check-ref-format.sh t/t1450-fsck.sh \ t/t2024-checkout-dwim.sh \ t/t2106-update-index-assume-unchanged.sh \ t/t3040-subprojects-basic.sh t/t3301-notes.sh \ t/t3308-notes-merge.sh t/t3423-rebase-reword.sh \ t/t3436-rebase-more-options.sh \ t/t4015-diff-whitespace.sh t/t4257-am-interactive.sh \ t/t5323-pack-redundant.sh t/t5401-update-hooks.sh \ t/t5511-refspec.sh t/t5526-fetch-submodules.sh \ t/t5529-push-errors.sh t/t5530-upload-pack-error.sh \ t/t5548-push-porcelain.sh \ t/t5552-skipping-fetch-negotiator.sh \ t/t5572-pull-submodule.sh t/t5608-clone-2gb.sh \ t/t5614-clone-submodules-shallow.sh \ t/t7508-status.sh t/t7606-merge-custom.sh \ t/t9302-fast-import-unpack-limit.sh We excluded one set of test scripts in these commands, though: the range of `git p4` tests. The reason? `git p4` stores the (foreign) remote branch in the branch called `p4/master`, which is obviously not the default branch. Manual analysis revealed that only five of these tests actually require a specific default branch name to pass; They were modified thusly: $ sed -i '/^ *\. \.\/lib-git-p4\.sh$/i\ GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\ export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\ ' t/t980[0167]*.sh t/t9811*.sh Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

rebase --skip: clean up commit message after a failed fixup/squash During a series of fixup/squash commands, the interactive rebase builds up a commit message with comments. This will be presented to the user in the editor if at least one of those commands was a `squash`. In any case, the commit message will be cleaned up eventually, removing all those intermediate comments, in the final step of such a fixup/squash chain. However, if the last fixup/squash command in such a chain fails with merge conflicts, and if the user then decides to skip it (or resolve it to a clean worktree and then continue the rebase), the current code fails to clean up the commit message. This commit fixes that behavior. The fix is quite a bit more involved than meets the eye because it is not only about the question whether we are `git rebase --skip`ing a fixup or squash. It is also about removing the skipped fixup/squash's commit message from the accumulated commit message. And it is also about the question whether we should let the user edit the final commit message or not ("Was there a squash in the chain *that was not skipped*?"). For example, in this case we will want to fix the commit message, but not open it in an editor: pick <- succeeds fixup <- succeeds squash <- fails, will be skipped This is where the newly-introduced `current-fixups` file comes in real handy. A quick look and we can determine whether there was a non-skipped squash. We only need to make sure to keep it up to date with respect to skipped fixup/squash commands. As a bonus, we can even avoid committing unnecessarily, e.g. when there was only one fixup, and it failed, and was skipped. To fix only the bug where the final commit message was not cleaned up properly, but without fixing the rest, would have been more complicated than fixing it all in one go, hence this commit lumps together more than a single concern. For the same reason, this commit also adds a bit more to the existing test case for the regression we just fixed. The diff is best viewed with --color-moved.

rebase: don't override --no-reschedule-failed-exec with config Fix a bug in how --no-reschedule-failed-exec interacts with rebase.rescheduleFailedExec=true being set in the config. Before this change the --no-reschedule-failed-exec config option would be overridden by the config. This bug happened because of the particulars of how "rebase" works v.s. most other git commands when it comes to parsing options and config: When we read the config and parse the CLI options we correctly prefer the --no-reschedule-failed-exec option over rebase.rescheduleFailedExec=true in the config. So far so good. However the --reschedule-failed-exec option doesn't take effect when the rebase starts (we'd just create a ".git/rebase-merge/reschedule-failed-exec" file if it was true). It only takes effect when the exec command fails, at which point we'll reschedule the failed "exec" command. Since we only wrote out the positive ".git/rebase-merge/reschedule-failed-exec" under --reschedule-failed-exec, but nothing with --no-reschedule-failed-exec we'll forget that we asked not to reschedule failed "exec", and would happily re-read the config and see that rebase.rescheduleFailedExec=true is set. So the config will effectively override the user having explicitly disabled the option on the command-line. Even more confusingly: Since rebase accepts different options based on its state there wasn't even a way to get around this with "rebase --continue --no-reschedule-failed-exec" (but you could of course set the config with "rebase -c ..."). I think the least bad way out of this is to declare that for such options and config whatever we decide at the beginning of the rebase goes. So we'll now always create either a "reschedule-failed-exec" or a "no-reschedule-failed-exec file at the start, not just the former if we decided we wanted the feature. With this new worldview you can no longer change the setting once a rebase has started except by manually removing the state files discussed above. I think making it work like that is the the least confusing thing we can do. In the future we might want to learn to change the setting in the middle by combining "--edit-todo" with "--[no-]reschedule-failed-exec", we currently don't support combining those options, or any other way to change the state in the middle of the rebase short of manually editing the files in ".git/rebase-merge/*". The bug being fixed here originally came about because of a combination of the behavior of the code added in d421afa0c66 (rebase: introduce --reschedule-failed-exec, 2018-12-10) and the addition of the config variable in 969de3ff0e0 (rebase: add a config option to default to --reschedule-failed-exec, 2018-12-10).
