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>

rev-list: make empty --stdin not an error When we originally did the series that contains 7ba826290a (revision: add rev_input_given flag, 2017-08-02) the intent was that "git rev-list --stdin </dev/null" would similarly become a successful noop. However, an attempt at the time to do that did not work[1]. The problem is that rev_input_given serves two roles: - it tells rev-list.c that it should not error out - it tells revision.c that it should not have the "default" ref kick (e.g., "HEAD" in "git log") We want to trigger the former, but not the latter. This is technically possible with a single flag, if we set the flag only after revision.c's revs->def check. But this introduces a rather subtle ordering dependency. Instead, let's keep two flags: one to denote when we got actual input (which triggers both roles) and one for when we read stdin (which triggers only the first). This does mean a caller interested in the first role has to check both flags, but there's only one such caller. And any future callers might want to make the distinction anyway (e.g., if they care less about erroring out, and more about whether revision.c soaked up our stdin). In fact, we already keep such a flag internally in revision.c for this purpose, so this is really just exposing that to the caller (and the old function-local flag can go away in favor of our new one).

revision: set rev_input_given in handle_revision_arg() Commit 7ba826290a (revision: add rev_input_given flag, 2017-08-02) added a flag to rev_info to tell whether we got any revision arguments. As explained there, this is necessary because some revision arguments may not produce any pending traversal objects, but should still inhibit default behaviors (e.g., a glob that matches nothing). However, it only set the flag in the globbing code, but not for revisions we get on the command-line or via stdin. This leads to two problems: - the command-line code keeps its own separate got_rev_arg flag; this isn't wrong, but it's confusing and an extra maintenance burden - even specifically-named rev arguments might end up not adding any pending objects: if --ignore-missing is set, then specifying a missing object is a noop rather than an error. And that leads to some user-visible bugs: - when deciding whether a default rev like "HEAD" should kick in, we check both got_rev_arg and rev_input_given. That means that "--ignore-missing $ZERO_OID" works on the command-line (where we set got_rev_arg) but not on --stdin (where we don't) - when rev-list decides whether it should complain that it wasn't given a starting point, it relies on rev_input_given. So it can't even get the command-line "--ignore-missing $ZERO_OID" right Let's consistently set the flag if we got any revision argument. That lets us clean up the redundant got_rev_arg, and fixes both of those bugs (but note there are three new tests: we'll confirm the already working git-log command-line case). A few implementation notes: - conceptually we want to set the flag whenever handle_revision_arg() finds an actual revision arg ("handles" it, you might say). But it covers a ton of cases with early returns. Rather than annotating each one, we just wrap it and use its success exit-code to set the flag in one spot. - the new rev-list test is in t6018, which is titled to cover globs. This isn't exactly a glob, but it made sense to stick it with the other tests that handle the "even though we got a rev, we have no pending objects" case, which are globs. - the tests check for the oid of a missing object, which it's pretty clear --ignore-missing should ignore. You can see the same behavior with "--ignore-missing a-ref-that-does-not-exist", because --ignore-missing treats them both the same. That's perhaps less clearly correct, and we may want to change that in the future. But the way the code and tests here are written, we'd continue to do the right thing even if it does.
