2020-11-19t34*: adjust the references to the default branch name "main"Libravatar Johannes Schindelin1-5/+5
Carefully excluding t3404, which sees independent development elsewhere at the time of writing, we use `main` as the default branch name in t34*. This trick was performed via $ (cd t && sed -i -e 's/master/main/g' -e 's/MASTER/MAIN/g' \ -e 's/Master/Main/g' -- t34*.sh && git checkout HEAD -- t34\*) This allows us to define `GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main` for those tests.

2020-11-19tests: mark tests relying on the current default for `init.defaultBranch`Libravatar Johannes Schindelin1-0/+3
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>
2020-04-28rebase: save autostash entry into stash reflog on --quitLibravatar Denton Liu1-0/+20
In a03b55530a (merge: teach --autostash option, 2020-04-07), the --autostash option was introduced for `git merge`. Notably, when `git merge --quit` is run with an autostash entry present, it is saved into the stash reflog. This is contrasted with the current behaviour of `git rebase --quit` where the autostash entry is simply just dropped out of existence. Adopt the behaviour of `git merge --quit` in `git rebase --quit` and save the autostash entry into the stash reflog instead of just deleting it.

2020-02-16rebase: rename the two primary rebase backendsLibravatar Elijah Newren1-11/+11
Two related changes, with separate rationale for each: Rename the 'interactive' backend to 'merge' because: * 'interactive' as a name caused confusion; this backend has been used for many kinds of non-interactive rebases, and will probably be used in the future for more non-interactive rebases than interactive ones given that we are making it the default. * 'interactive' is not the underlying strategy; merging is. * the directory where state is stored is not called .git/rebase-interactive but .git/rebase-merge. Rename the 'am' backend to 'apply' because: * Few users are familiar with git-am as a reference point. * Related to the above, the name 'am' makes sentences in the documentation harder for users to read and comprehend (they may read it as the verb from "I am"); avoiding this difficult places a large burden on anyone writing documentation about this backend to be very careful with quoting and sentence structure and often forces annoying redundancy to try to avoid such problems. * Users stumble over pronunciation ("am" as in "I am a person not a backend" or "am" as in "the first and thirteenth letters in the alphabet in order are "A-M"); this may drive confusion when one user tries to explain to another what they are doing. * While "am" is the tool driving this backend, the tool driving git-am is git-apply, and since we are driving towards lower-level tools for the naming of the merge backend we may as well do so here too. * The directory where state is stored has never been called .git/rebase-am, it was always called .git/rebase-apply. For all the reasons listed above: * Modify the documentation to refer to the backends with the new names * Provide a brief note in the documentation connecting the new names to the old names in case users run across the old names anywhere (e.g. in old release notes or older versions of the documentation) * Change the (new) --am command line flag to --apply * Rename some enums, variables, and functions to reinforce the new backend names for us as well.

2019-07-08t3420: remove progress lines before comparing outputLibravatar Phillip Wood1-8/+11
Some of the tests check the output of rebase is what we expect. These were added after a regression that added unwanted stash output when using --autostash. They are useful as they prevent unintended changes to the output of the various rebase commands. However they also include all the progress output which is less useful as it only tests what would be written to a dumb terminal which is not the normal use case. The recent changes to fix clearing the line when printing progress necessarily meant making an ugly change to these tests. Address this my removing the progress output before comparing it to the expected output. We do this by removing everything before the final "\r" on each line as we don't care about the progress indicator, but we do care about what is printed immediately after it.

2019-06-27rebase: fix garbled progress display with '-x'Libravatar SZEDER Gábor1-2/+2
When running a command with the 'exec' instruction during an interactive rebase session, or for a range of commits using 'git rebase -x', the output can be a bit garbled when the name of the command is short enough: $ git rebase -x true HEAD~5 Executing: true Executing: true Executing: true Executing: true Executing: true) Successfully rebased and updated refs/heads/master. Note the ')' at the end of the last line. It gets more garbled as the range of commits increases: $ git rebase -x true HEAD~50 Executing: true) [ repeated 3 more times ] Executing: true0) [ repeated 44 more times ] Executing: true00) Successfully rebased and updated refs/heads/master. Those extra numbers and ')' are remnants of the previously displayed "Rebasing (N/M)" progress lines that are usually completely overwritten by the "Executing: <cmd>" lines, unless 'cmd' is short and the "N/M" part is long. Make sure that the previously displayed "Rebasing (N/M)" line is cleared by using the term_clear_line() helper function added in the previous patch. Do so only when not being '--verbose', because in that case these "Rebasing (N/M)" lines are not printed as progress (i.e. as lines with '\r' at the end), but as "regular" output (with '\n' at the end). A couple of other rebase commands print similar messages, e.g. "Stopped at <abbrev-oid>... <subject>" for the 'edit' or 'break' commands, or the "Successfully rebased and updated <full-ref>." at the very end. These are so long that they practically always overwrite that "Rebasing (N/M)" progress line, but let's be prudent, and clear the last line before printing these, too. In 't3420-rebase-autostash.sh' two helper functions prepare the expected output of four tests that check the full output of 'git rebase' and thus are affected by this change, so adjust their expectations to account for the new line clearing. Note that this patch doesn't completely eliminate the possibility of similar garbled outputs, e.g. some error messages from rebase or the "Auto-merging <file>" message from within the depths of the merge machinery might not be long enough to completely cover the last "Rebasing (N/M)" line. This patch doesn't do anything about them, because dealing with them individually would result in way too much churn, while having a catch-all term_clear_line() call in the common code path of pick_commits() would hide the "Rebasing (N/M)" line way too soon, and it would either flicker or be invisible.

2019-01-07rebase: implement --merge via the interactive machineryLibravatar Elijah Newren1-72/+6
As part of an ongoing effort to make rebase have more uniform behavior, modify the merge backend to behave like the interactive one, by re-implementing it on top of the latter. Interactive rebases are implemented in terms of cherry-pick rather than the merge-recursive builtin, but cherry-pick also calls into the recursive merge machinery by default and can accept special merge strategies and/or special strategy options. As such, there really is not any need for having both git-rebase--merge and git-rebase--interactive anymore. Delete git-rebase--merge.sh and instead implement it in builtin/rebase.c. This results in a few deliberate but small user-visible changes: * The progress output is modified (see t3406 and t3420 for examples) * A few known test failures are now fixed (see t3421) * bash-prompt during a rebase --merge is now REBASE-i instead of REBASE-m. Reason: The prompt is a reflection of the backend in use; this allows users to report an issue to the git mailing list with the appropriate backend information, and allows advanced users to know where to search for relevant control files. (see t9903) testcase modification notes: t3406: --interactive and --merge had slightly different progress output while running; adjust a test to match the new expectation t3420: these test precise output while running, but rebase--am, rebase--merge, and rebase--interactive all were built on very different commands (am, merge-recursive, cherry-pick), so the tests expected different output for each type. Now we expect --merge and --interactive to have the same output. t3421: --interactive fixes some bugs in --merge! Wahoo! t9903: --merge uses the interactive backend so the prompt expected is now REBASE-i. Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-08-22t3420-rebase-autostash: don't try to grep non-existing filesLibravatar SZEDER Gábor1-4/+4
Several tests in 't3420-rebase-autostash.sh' start various rebase processes that are expected to fail because of merge conflicts. These tests then run '! grep' to ensure that the autostash feature did its job, and the dirty contents of a file is gone. However, due to the test repo's history and the choice of upstream branch that file shouldn't exist in the conflicted state at all. Consequently, this 'grep' doesn't fail as expected, because it can't find the dirty content, but it fails because it can't open the file. Tighten this check by using 'test_path_is_missing' instead, thereby avoiding unexpected errors from 'grep' as well.

2013-05-29rebase: implement --[no-]autostash and rebase.autostashLibravatar Ramkumar Ramachandra1-0/+148
This new feature allows a rebase to be executed on a dirty worktree or index. It works by creating a temporary "dangling merge commit" out of the worktree and index changes (via 'git stash create'), and automatically applying it after a successful rebase or abort. rebase stores the SHA-1 hex of the temporary merge commit, along with the rest of the rebase state, in either .git/{rebase-merge,rebase-apply}/autostash depending on the kind of rebase. Since $state_dir is automatically removed at the end of a successful rebase or abort, so is the autostash. The advantage of this approach is that we do not affect the normal stash's reflogs, making the autostash invisible to the end-user. This means that you can use 'git stash' during a rebase as usual. When the autostash application results in a conflict, we push $state_dir/autostash onto the normal stash and remove $state_dir ending the rebase. The user can inspect the stash, and pop or drop at any time. Most significantly, this feature means that a caller like pull (with pull.rebase set to true) can easily be patched to remove the require_clean_work_tree restriction.
