* update-ref: add test cases for bare repositoryCornelius Weig2017-01-31
| | | | | | | | | | | | | | | The default behavior of update-ref to create reflogs differs in repositories with worktree and bare ones. The existing tests cover only the behavior of repositories with worktree. This commit adds tests that assert the correct behavior in bare repositories for update-ref. Two cases are covered: - If core.logAllRefUpdates is not set, no reflogs should be created - If core.logAllRefUpdates is true, reflogs should be created Signed-off-by: Cornelius Weig <cornelius.weig@tngtech.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* refs: add option core.logAllRefUpdates = alwaysCornelius Weig2017-01-31
| | | | | | | | | | | | | | | | | | | | | | | When core.logallrefupdates is true, we only create a new reflog for refs that are under certain well-known hierarchies. The reason is that we know that some hierarchies (like refs/tags) are not meant to change, and that unknown hierarchies might not want reflogs at all (e.g., a hypothetical refs/foo might be meant to change often and drop old history immediately). However, sometimes it is useful to override this decision and simply log for all refs, because the safety and audit trail is more important than the performance implications of keeping the log around. This patch introduces a new "always" mode for the core.logallrefupdates option which will log updates to everything under refs/, regardless where in the hierarchy it is (we still will not log things like ORIG_HEAD and FETCH_HEAD, which are known to be transient).

| * refs: resolve symbolic refs firstMichael Haggerty2016-06-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before committing ref updates, split symbolic ref updates into two parts: an update to the underlying ref, and a log-only update to the symbolic ref. This ensures that both references are locked correctly during the transaction, including while their reflogs are updated. Similarly, if the reference pointed to by HEAD is modified directly, add a separate log-only update to HEAD, rather than leaving the job of updating HEAD's reflog to commit_ref_update(). This change ensures that HEAD is locked correctly while its reflog is being modified, as well as being cheaper (HEAD only needs to be resolved once). This makes use of a new function, lock_raw_ref(), which is analogous to read_raw_ref(), but acquires a lock on the reference before reading it. This change still has two problems: * There are redundant read_ref_full() reference lookups. * It is still possible to get incorrect reflogs for symbolic references if there is a concurrent update by another process, since the old_oid of a symref is determined before the lock on the pointed-to ref is held. Both problems will soon be fixed. Signed-off-by: David Turner <dturner@twopensource.com> Signed-off-by: Junio C Hamano <gitster@pobox.com> Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> WIP

* | tests: use test_i18n* functions to suppress false positivesVasco Almeida2016-06-17
|/ | | | | | | | | | | | | | | | | The test functions test_i18ncmp and test_i18ngrep pretend success if run under GETTEXT_POISON. By using those functions to test output which is correctly marked as translatable, enables one to detect if the strings newly marked for translation are from plumbing output. If they are indeed from plumbing, the test would fail, and the string should be unmarked, since it is not seen by users. Thus, it is productive to not have false positives when running the test under GETTEXT_POISON. This commit replaces normal test functions by their i18n aware variants in use-cases know to be correctly marked for translation, suppressing false positives.

Non-atomic updates ================== The atomicity of the reference transaction depends on all pre-checks being done in the first loop, before any changes have started being committed in the second loop. The problem is that write_ref_to_lockfile() (previously part of write_ref_sha1()), which is called from the second loop, contains two more checks: * It verifies that new_sha1 is a valid object * If the reference being updated is a branch, it verifies that new_sha1 points at a commit object (as opposed to a tag, tree, or blob). If either of these checks fails, the "transaction" is aborted during the second loop. But this might happen after some reference updates have already been permanently committed. In other words, the all-or-nothing promise of "git update-ref --stdin" could be violated. So these checks have to be moved to the first loop. File descriptor exhaustion ========================== The old code locked all of the references in the first loop, leaving all of the lockfiles open until later loops. Since we might be updating a lot of references, this could result in file descriptor exhaustion. The solution ============ After this patch, the code looks like for update in updates: acquire locks and check old_sha if changing value: write_ref_to_lockfile() else: close_ref() for update in updates: if changing value: commit_ref_update() for update in updates: if deleting value: unlink() rewrite packed-refs file for update in updates: if reference still locked: unlock_ref() This fixes both problems: 1. The pre-checks in write_ref_to_lockfile() are now done in the first loop, before any changes have been committed. If any of the checks fails, the whole transaction can now be rolled back correctly. 2. All lockfiles are closed in the first loop immediately after they are created (either by write_ref_to_lockfile() or by close_ref()). This means that there is never more than one open lockfile at a time, preventing file descriptor exhaustion. To simplify the bookkeeping across loops, add a new REF_NEEDS_COMMIT bit to update->flags, which keeps track of whether the corresponding lockfile needs to be committed, as opposed to just unlocked. (Since "struct ref_update" is internal to the refs module, this change is not visible to external callers.) This change fixes two tests in t1400.

* update-ref: fix "verify" command with missing <oldvalue>Michael Haggerty2014-12-11
| | | | | | | | | | | | | | | | | | | | | | | | If "git update-ref --stdin" was given a "verify" command with no "<newvalue>" at all (not even zeros), the code was mistakenly setting have_old=0 (and leaving old_sha1 uninitialized). But this is incorrect: this command is supposed to verify that the reference doesn't exist. So in this case we really need old_sha1 to be set to null_sha1 and have_old to be set to 1. Moreover, since have_old was being set to zero, *no* check of the old value was being done, so the new value of the reference was being set unconditionally to the value in new_sha1. new_sha1, in turn, was set to null_sha1 in the expectation that that was the old value and it shouldn't be changed. But because the precondition was not being checked, the result was that the reference was being deleted unconditionally. So, if <oldvalue> is missing, set have_old unconditionally and set old_sha1 to null_sha1.

The new interface means that the calling functions, parse_cmd_*(), don't have to interpret the result differently based on the line_termination mode that is in effect.

But in fact, the definition of the input format requires arguments to be terminated by SP or NUL, so *this* argument is already erroneous and parse_arg() should diagnose the problem. So teach parse_arg() to verify that C-quoted arguments are terminated correctly. If not, emit a more specific error message. There is no corresponding error case of a non-C-quoted argument that is not terminated correctly, because the end of a non-quoted argument is *by definition* a space or NUL, so there is no way to insert other junk between the "end" of the argument and the argument terminator.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old version was passing (among other things) update SP refs/heads/c NUL NUL 0{40} NUL to "git update-ref -z --stdin" to test whether the old-value check for c is working. But the <newvalue> is empty, which is a bit off the beaten track. So, to be sure that we are testing what we want to test, provide an actual <newvalue> on the "update" line.

| * t1400: fix name and expected result of one testMichael Haggerty2014-04-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The test stdin -z create ref fails with zero new value actually passes an empty new value, not a zero new value. So rename the test s/zero/empty/, and change the expected error from fatal: create $c given zero new value to fatal: create $c missing <newvalue> Of course, this makes the test fail now, because although "git update-ref" tries to distinguish between these two errors, it does not succeed in this situation. Fixing it is more than a one-liner, so mark the test test_expect_failure for now. The failure will be fixed later in this patch series.

* Fix failure to delete a packed ref through a symrefJohan Herland2012-10-21
| | | | | | | | | | | | | | When deleting a ref through a symref (e.g. using 'git update-ref -d HEAD' to delete refs/heads/master), we would remove the loose ref, but a packed version of the same ref would remain, the end result being that instead of deleting refs/heads/master we would appear to reset it to its state as of the last repack. This patch fixes the issue, by making sure we pass the correct ref name when invoking repack_without_ref() from within delete_ref().

| | | | | | | | | | | | | | | | | | | | | | | | As t/README explains: When a gitcommand dies due to a segfault, test_must_fail diagnoses it as an error; "! git <command>" treats it as just another expected failure, which would let such a bug go unnoticed.

| | | | | | | | | | | | Several old tests were written before test_cmp was introduced, convert these to test_cmp. If were are at it, fix the order of the arguments where necessary to make expected come first, so the command shows how the test result deviates from the correct output.

* update-ref --no-deref -d: handle the case when the pointed ref is packedMiklos Vajna2008-10-31
| | | | | | | | | | | | In this case we did nothing in the past, but we should delete the reference in fact. The problem was that when the symref is not packed but the referenced ref is packed, then we assumed that the symref is packed as well, but symrefs are never packed.

* t/: Use "test_must_fail git" instead of "! git"Stephan Beyer2008-07-13
| | | | | | | | | | | | | | | This patch changes every occurrence of "! git" -- with the meaning that a git call has to gracefully fail -- into "test_must_fail git". This is useful to - make sure the test does not fail because of a signal, e.g. SIGSEGV, and - advertise the use of "test_must_fail" for new tests.
