2021-11-01leak tests: mark some rev-parse tests as passing with SANITIZE=leakLibravatar Ævar Arnfjörð Bjarmason1-0/+1
Mark some tests that match "*rev-parse*" as passing when git is compiled with SANITIZE=leak. They'll now be listed as running under the "GIT_TEST_PASSING_SANITIZE_LEAK=true" test mode (the "linux-leaks" CI target).

2021-01-11refs: allow @{n} to work with n-sized reflogLibravatar Denton Liu1-2/+2
This sequence works $ git checkout -b newbranch $ git commit --allow-empty -m one $ git show -s newbranch@{1} and shows the state that was immediately after the newbranch was created. But then if you do $ git reflog expire --expire=now refs/heads/newbranch $ git commit --allow=empty -m two $ git show -s newbranch@{1} you'd be scolded with fatal: log for 'newbranch' only has 1 entries While it is true that it has only 1 entry, we have enough information in that single entry that records the transition between the state in which the tip of the branch was pointing at commit 'one' to the new commit 'two' built on it, so we should be able to answer "what object newbranch was pointing at?". But we refuse to do so. Make @{0} the special case where we use the new side to look up that entry. Otherwise, look up @{n} using the old side of the (n-1)th entry of the reflog.

2020-11-19t[01]*: adjust the references to the default branch name "main"Libravatar Johannes Schindelin1-15/+15
Carefully excluding t1309, which sees independent development elsewhere at the time of writing, we transition above-mentioned tests to the default branch name `main`. This trick was performed via $ (cd t && sed -i -e 's/master/main/g' -e 's/MASTER/MAIN/g' \ -e 's/Master/Main/g' -e 's/naster/nain/g' -- t[01]*.sh && git checkout HEAD -- t1309\*) Note that t5533 contains a variation of the name `master` (`naster`) that we rename here, too. 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$/i\ GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\ export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\ ' t/t980[0167]*.sh t/t9811*.sh Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-11-10rev-parse: handle --end-of-optionsLibravatar Jeff King1-0/+13
We taught rev-list a new way to separate options from revisions in 19e8789b23 (revision: allow --end-of-options to end option parsing, 2019-08-06), but rev-parse uses its own parser. It should know about --end-of-options not only for consistency, but because it may be presented with similarly ambiguous cases. E.g., if a caller does: git rev-parse "$rev" -- "$path" to parse an untrusted input, then it will get confused if $rev contains an option-like string like "--local-env-vars". Or even "--not-real", which we'd keep as an option to pass along to rev-list. Or even more importantly: git rev-parse --verify "$rev" can be confused by options, even though its purpose is safely parsing untrusted input. On the plus side, it will always fail the --verify part, as it will not have parsed a revision, so the caller will generally "fail closed" rather than continue to use the untrusted string. But it will still trigger whatever option was in "$rev"; this should be mostly harmless, since rev-parse options are all read-only, but I didn't carefully audit all paths. This patch lets callers write: git rev-parse --end-of-options "$rev" -- "$path" and: git rev-parse --verify --end-of-options "$rev" which will both treat "$rev" always as a revision parameter. The latter is a bit clunky. It would be nicer if we had defined "--verify" to require that its next argument be the revision. But we have not historically done so, and: git rev-parse --verify -q "$rev" does currently work. I added a test here to confirm that we didn't break that. A few implementation notes: - We don't document --end-of-options explicitly in commands, but rather in gitcli(7). So I didn't give it its own section in git-rev-parse(1). But I did call it out specifically in the --verify section, and include it in the examples, which should show best practices. - We don't have to re-indent the main option-parsing block, because we can combine our "did we see end of options" check with "does it start with a dash". The exception is the pre-setup options, which need their own block. - We do however have to pull the "--" parsing out of the "does it start with dash" block, because we want to parse it even if we've seen --end-of-options. - We'll leave "--end-of-options" in the output. This is probably not technically necessary, as a careful caller will do: git rev-parse --end-of-options $revs -- $paths and anything in $revs will be resolved to an object id. However, it does help a slightly less careful caller like: git rev-parse --end-of-options $revs_or_paths where a path "--foo" will remain in the output as long as it also exists on disk. In that case, it's helpful to retain --end-of-options to get passed along to rev-list, s it would otherwise see just "--foo".

2016-10-10files_read_raw_ref: avoid infinite loop on broken symlinksLibravatar Jeff King1-0/+5
Our ref resolution first runs lstat() on any path we try to look up, because we want to treat symlinks specially (by resolving them manually and considering them symrefs). But if the results of `readlink` do _not_ look like a ref, we fall through to treating it like a normal file, and just read the contents of the linked path. Since fcb7c76 (resolve_ref_unsafe(): close race condition reading loose refs, 2013-06-19), that "normal file" code path will stat() the file and if we see ENOENT, will jump back to the lstat(), thinking we've seen inconsistent results between the two calls. But for a symbolic ref, this isn't a race: the lstat() found the symlink, and the stat() is looking at the path it points to. We end up in an infinite loop calling lstat() and stat(). We can fix this by avoiding the retry-on-inconsistent jump when we know that we found a symlink. While we're at it, let's add a comment explaining why the symlink case gets to this code in the first place; without that, it is not obvious that the correct solution isn't to avoid the stat() code path entirely.

2015-07-28tests: remove some direct access to .git/logsLibravatar David Turner1-6/+3
Alternate refs backends might store reflogs somewhere other than .git/logs. Change most test code that directly accesses .git/logs to instead use git reflog commands. There are still a few tests which need direct access to reflogs: to check reflog permissions, to manually create reflogs from scratch, to save/restore reflogs, to check the format of raw reflog data, and to remove not just reflog contents, but the reflogs themselves. All cases which don't need direct access have been modified. Signed-off-by: David Turner <dturner@twopensource.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-09-19refs: make rev-parse --quiet actually quietLibravatar David Aguilar1-0/+27
When a reflog is deleted, e.g. when "git stash" clears its stashes, "git rev-parse --verify --quiet" dies: fatal: Log for refs/stash is empty. The reason is that the get_sha1() code path does not allow us to suppress this message. Pass the flags bitfield through get_sha1_with_context() so that read_ref_at() can suppress the message. Use get_sha1_with_context1() instead of get_sha1() in rev-parse so that the --quiet flag is honored. Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2010-09-27t1503: Fix arithmetic expansion syntax error when using dashLibravatar Ramsay Jones1-2/+2
On systems which have dash as /bin/sh, such as Ubuntu, the final test (master@{n} for various n) fails with a syntax error while processing an arithmetic expansion. The syntax error is caused by using a bare name ('N') as a variable reference in the expression. In order to avoid the syntax error, we spell the variable reference as '$N' rather than simply 'N'.
