checkout $tree $path: do not clobber local changes in $path not in $tree Checking paths out of a tree is (currently) defined to do: - Grab the paths from the named tree that match the given pathspec, and add them to the index; - Check out the contents from the index for paths that match the pathspec to the working tree; and while at it - If the given pathspec did not match anything, suspect a typo from the command line and error out without updating the index nor the working tree. Suppose that the branch you are working on has dir/myfile, and the "other" branch has dir/other but not dir/myfile. Further imagine that you have either modified or removed dir/myfile in your working tree, but you have not run "git add dir/myfile" or "git rm dir/myfile" to tell Git about your local change. Running $ git checkout other dir would add dir/other to the index with the contents taken out of the "other" branch, and check out the paths from the index that match the pathspec "dir", namely, "dir/other" and "dir/myfile", overwriting your local changes to "dir/myfile", even though "other" branch does not even know about that file. Fix it by updating the working tree only with the index entries that was read from the "other" tree. Signed-off-by: Junio C Hamano <gitster@pobox.com>

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>

checkout: fix "branch info" memory leaks The "checkout" command is one of the main sources of leaks in the test suite, let's fix the common ones by not leaking from the "struct branch_info". Doing this is rather straightforward, albeit verbose, we need to xstrdup() constant strings going into the struct, and free() the ones we clobber as we go along. This also means that we can delete previous partial leak fixes in this area, i.e. the "path_to_free" accounting added by 96ec7b1e708 (Convert resolve_ref+xstrdup to new resolve_refdup function, 2011-12-13). There was some discussion about whether "we should retain the "const char *" here and cast at free() time, or have it be a "char *". Since this is not a public API with any sort of API boundary let's use "char *", as is already being done for the "refname" member of the same struct. The tests to mark as passing were found with: rm .prove; GIT_SKIP_TESTS=t0027 prove -j8 --state=save t[0-9]*.sh :: --immediate # apply & compile this change prove -j8 --state=failed :: --immediate I.e. the ones that were newly passing when the --state=failed command was run. I left out "t3040-subprojects-basic.sh" and "t4131-apply-fake-ancestor.sh" to to optimization-level related differences similar to the ones noted in[1], except that these would be something the current 'linux-leaks' job would run into. 1. https://lore.kernel.org/git/cover-v3-0.6-00000000000-20211022T175227Z-avarab@gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

The command's behavior now is modified slightly: unmerged entries that match $path, but not updated by $tree, are now NOT touched. Although this should be considered a bug fix, not a regression. A new test is added for this change. And while at there, free ps_matched after use. The following command is tested on webkit, 215k entries. The pattern is chosen mainly to make match_pathspec sweat: git checkout -- "*[a-zA-Z]*[a-zA-Z]*[a-zA-Z]*" before after real 0m3.493s 0m2.737s user 0m2.239s 0m1.586s sys 0m1.252s 0m1.151s Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

checkout $tree: do not throw away unchanged index entries When we "git checkout $tree", we pull paths from $tree into the index, and then check the resulting entries out to the worktree. Our method for the first step is rather heavy-handed, though; it clobbers the entire existing index entry, even if the content is the same. This means we lose our stat information, leading checkout_entry to later rewrite the entire file with identical content. Instead, let's see if we have the identical entry already in the index, in which case we leave it in place. That lets checkout_entry do the right thing. Our tests cover two interesting cases: 1. We make sure that a file which has no changes is not rewritten. 2. We make sure that we do update a file that is unchanged in the index (versus $tree), but has working tree changes. We keep the old index entry, and checkout_entry is able to realize that our stat information is out of date. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

checkout.c: unstage empty deleted ita files It is possible to delete a committed file from the index and then add it as intent-to-add. After `git checkout HEAD <pathspec>`, the file should be identical in the index and HEAD. The command already works correctly if the file has contents in HEAD. This patch provides the desired behavior even when the file is empty in HEAD. `git checkout HEAD <pathspec>` calls tree.c:read_tree_1(), with fn pointing to checkout.c:update_some(). update_some() creates a new cache entry but discards it when its mode and oid match those of the old entry. A cache entry for an ita file and a cache entry for an empty file have the same oid. Therefore, an empty deleted ita file previously passed both of these checks, and the new entry was discarded, so the file remained unchanged in the index. After this fix, if the file is marked as ita in the cache, then we avoid discarding the new entry and add the new entry to the cache instead. This change should not affect newly added ita files. For those, inside tree.c:read_tree_1(), tree_entry_interesting() returns entry_not_interesting, so fn is never called.

checkout $tree $path: do not clobber local changes in $path not in $tree Checking paths out of a tree is (currently) defined to do: - Grab the paths from the named tree that match the given pathspec, and add them to the index; - Check out the contents from the index for paths that match the pathspec to the working tree; and while at it - If the given pathspec did not match anything, suspect a typo from the command line and error out without updating the index nor the working tree. Suppose that the branch you are working on has dir/myfile, and the "other" branch has dir/other but not dir/myfile. Further imagine that you have either modified or removed dir/myfile in your working tree, but you have not run "git add dir/myfile" or "git rm dir/myfile" to tell Git about your local change. Running $ git checkout other dir would add dir/other to the index with the contents taken out of the "other" branch, and check out the paths from the index that match the pathspec "dir", namely, "dir/other" and "dir/myfile", overwriting your local changes to "dir/myfile", even though "other" branch does not even know about that file. Fix it by updating the working tree only with the index entries that was read from the "other" tree. Signed-off-by: Junio C Hamano <gitster@pobox.com>
