2022-03-17fetch+push tests: use "test_hook" and "test_when_finished" patternLibravatar Ævar Arnfjörð Bjarmason1-103/+88
Change the "t5516-fetch-push.sh" test code to make use of the new "test_hook" helper, and to use "test_when_finished" to have tests clean up their own state, instead of relying on subsequent tests to clean the trash directory. Before this each test would have been responsible for cleaning up after a preceding test (which may or may not have run, e.g. if --run or "GIT_SKIP_TESTS" was used), now each test will instead clean up after itself. In order to use both "test_hook" and "test_when_finished" we need to move them out of sub-shells, which requires some refactoring. While we're at it split up the "push with negotiation" test, now the middle of the test doesn't need to "rm event", and since it delimited two halves that were testing two different things the end-state is easier to read and reason about. While changing these lines make the minor change from "-fr" to "-rf" as the "rm" argument, some of them used it already, it's more common in the test suite, and it leaves the end-state of the file with more consistency.

2022-03-17bugreport tests: tighten up "git bugreport -s hooks" testLibravatar Ævar Arnfjörð Bjarmason1-11/+15
Amend a test added in 788a776069b (bugreport: collect list of populated hooks, 2020-05-07) to "test_cmp" for the expected output, instead of selectively using "grep" to check for specific things we either expect or don't expect in the output. As noted in a preceding commit our .git/hooks directory already contains *.sample hooks, so we have no need to clobber the prepare-commit-msg.sample hook in particular. Instead we should assert that those *.sample hooks are not included in the output, and for good measure let's add a new "unknown-hook", to check that we only look through our own known hooks. See cfe853e66be (hook-list.h: add a generated list of hooks, like config-list.h, 2021-09-26) for how we generate that data. We're intentionally not piping the "actual" output through "sort" or similar, we'd also like to check that our reported hooks are sorted.

2022-03-17tests: assume the hooks are disabled by defaultLibravatar Ævar Arnfjörð Bjarmason3-5/+1
Stop moving the .git/hooks directory out of the way, or creating it during test setup. Instead assume that it will contain harmless *.sample files. That we can assume that is discussed in point #4 of f0d4d398e28 (test-lib: split up and deprecate test_create_repo(), 2021-05-10), those parts of this could and should have been done in that change. Removing the "mkdir -p" here will then validate that our templates are being used, since we'd subsequently fail to create a hook in that directory if it didn't exist. Subsequent commits will have those hooks created by a "test_hook" wrapper, which will then being doing that same validation.

2022-03-17test-lib-functions: add and use a "test_hook" wrapperLibravatar Ævar Arnfjörð Bjarmason13-43/+97
Add a "test_hook" wrapper similar to the existing "test_config" wrapper added in d960c47a881 (test-lib: add helper functions for config, 2011-08-17). This wrapper: - Will clean up the hook with "test_when_finished", unless --setup is provided. - Will error if we clobber a hook, unless --clobber is provided. - Takes a name like "update" instead of ".git/hooks/update". - Accepts -C <dir>, like "test_config" and "test_commit". By using a wrapper we'll be able to easily change all the hook-related code that assumes that the template-created ".git/hooks" directory is created by "init", "clone" etc. once another topic follows-up and changes the test suite to stop creating trash directories using those templates. In addition this will make it easy to have the hooks configured using the "configuration-based hooks" topic, once we get around to integrating that. I.e. we'll be able to run the tests in a mode where we sometimes create a .git/hooks/<name>, and other times create a script in another location, and point the relevant configuration snippet to it.

2022-03-16fetch: fetch unpopulated, changed submodulesLibravatar Glen Choo1-2/+266
"git fetch --recurse-submodules" only considers populated submodules (i.e. submodules that can be found by iterating the index), which makes "git fetch" behave differently based on which commit is checked out. As a result, even if the user has initialized all submodules correctly, they may not fetch the necessary submodule commits, and commands like "git checkout --recurse-submodules" might fail. Teach "git fetch" to fetch cloned, changed submodules regardless of whether they are populated. This is in addition to the current behavior of fetching populated submodules (which is always attempted regardless of what was fetched in the superproject, or even if nothing was fetched in the superproject). A submodule may be encountered multiple times (via the list of populated submodules or via the list of changed submodules). When this happens, "git fetch" only reads the 'populated copy' and ignores the 'changed copy'. Amend the verify_fetch_result() test helper so that we can assert on which 'copy' is being read.

2022-03-15cat-file: skip expanding default formatLibravatar John Cai1-0/+12
When format is passed into --batch, --batch-check, --batch-command, the format gets expanded. When nothing is passed in, the default format is set and the expand_format() gets called. We can save on these cycles by hardcoding how to print the information when nothing is passed as the format, or when the default format is passed. There is no need for the fully expanded format with the default. Since batch_object_write() happens on every object provided in batch mode, we get a nice performance improvement. git rev-list --all > /tmp/all-obj.txt git cat-file --batch-check </tmp/all-obj.txt with HEAD^: Time (mean ± σ): 57.6 ms ± 1.7 ms [User: 51.5 ms, System: 6.2 ms] Range (min … max): 54.6 ms … 64.7 ms 50 runs with HEAD: Time (mean ± σ): 49.8 ms ± 1.7 ms [User: 42.6 ms, System: 7.3 ms] Range (min … max): 46.9 ms … 55.9 ms 56 runs If nothing is provided as a format argument, or if the default format is passed, skip expanding of the format and print the object info with a default format.

2022-03-14stash: make internal resets quiet and refresh indexLibravatar Victoria Dye1-0/+33
Add the options '-q' and '--refresh' to the 'git reset' executed in 'reset_head()', and '--refresh' to the 'git reset -q' executed in 'do_push_stash(...)'. 'stash' is implemented such that git commands invoked as part of it (e.g., 'clean', 'read-tree', 'reset', etc.) have their informational output silenced. However, the 'reset' in 'reset_head()' is *not* called with '-q', leading to the potential for a misleading printout from 'git stash apply --index' if the stash included a removed file: Unstaged changes after reset: D <deleted file> Not only is this confusing in its own right (since, after the reset, 'git stash' execution would stage the deletion in the index), it would be printed even when the stash was applied with the '-q' option. As a result, the messaging is removed entirely by calling 'git status' with '-q'. Additionally, because the default behavior of 'git reset -q' is to skip refreshing the index, but later operations in 'git stash' subcommands expect a non-stale index, enable '--refresh' as well.

2022-03-14reset: introduce --[no-]refresh option to --mixedLibravatar Victoria Dye1-7/+66
Add a new --[no-]refresh option that is intended to explicitly determine whether a mixed reset should end in an index refresh. Starting at 9ac8125d1a (reset: don't compute unstaged changes after reset when --quiet, 2018-10-23), using the '--quiet' option results in skipping the call to 'refresh_index(...)' at the end of a mixed reset with the goal of improving performance. However, by coupling behavior that modifies the index with the option that silences logs, there is no way for users to have one without the other (i.e., silenced logs with a refreshed index) without incurring the overhead of a separate call to 'git update-index --refresh'. Furthermore, there is minimal user-facing documentation indicating that --quiet skips the index refresh, potentially leading to unexpected issues executing commands after 'git reset --quiet' that do not themselves refresh the index (e.g., internals of 'git stash', 'git read-tree'). To mitigate these issues, '--[no-]refresh' and 'reset.refresh' are introduced to provide a dedicated mechanism for refreshing the index. When either is set, '--quiet' and 'reset.quiet' revert to controlling only whether logs are silenced and do not affect index refresh.

2022-03-14repack: add config to skip updating server infoLibravatar Patrick Steinhardt1-0/+18
By default, git-repack(1) will update server info that is required by the dumb HTTP transport. This can be skipped by passing the `-n` flag, but what we're noticably missing is a config option to permanently disable updating this information. Add a new option "repack.updateServerInfo" which can be used to disable the logic. Most hosting providers have turned off the dumb HTTP protocol anyway, and on the client-side it woudln't typically be useful either. Giving a persistent way to disable this feature thus makes quite some sense to avoid wasting compute cycles and storage.

By default, git-repack(1) runs `update_server_info()` to generate info required for the dumb HTTP protocol. This can be disabled via the `-n` flag, which then sets the `no_update_server_info` flag. Further down the code this leads to some double-negation logic, which is about to become more confusing as we're about to add a new config which allows the user to permanently disable generation of the info. Refactor the code to avoid the double-negation and add some tests which verify that the flag continues to work as expected.

2022-03-13name-rev: use generation numbers if availableLibravatar Jacob Keller1-0/+118
If a commit in a sequence of linear history has a non-monotonically increasing commit timestamp, git name-rev might not properly name the commit. This occurs because name-rev uses a heuristic of the commit date to avoid searching down tags which lead to commits that are older than the named commit. This is intended to avoid work on larger repositories. This heuristic impacts git name-rev, and by extension git describe --contains which is built on top of name-rev. Further more, if --all or --annotate-stdin is used, the heuristic is not enabled because the full history has to be analyzed anyways. This results in some confusion if a user sees that --annotate-stdin works but a normal name-rev does not. If the repository has a commit graph, we can use the generation numbers instead of using the commit dates. This is essentially the same check except that generation numbers make it exact, where the commit date heuristic could be incorrect due to clock errors. Since we're extending the notion of cutoff to more than one variable, create a series of functions for setting and checking the cutoff. This avoids duplication and moves access of the global cutoff and generation_cutoff to as few functions as possible. Add several test cases including a test that covers the new commitGraph behavior, as well as tests for --all and --annotate-stdin with and without commitGraphs.

2022-03-09clone: fail gracefully when cloning filtered bundleLibravatar Derrick Stolee1-0/+12
Users can create a new repository using 'git clone <bundle-file>'. The new "@filter" capability for bundles means that we can generate a bundle that does not contain all reachable objects, even if the header has no negative commit OIDs. It is feasible to think that we could make a filtered bundle work with the command git clone --filter=$filter --bare <bundle-file> or possibly replacing --bare with --no-checkout. However, this requires having some repository-global config that specifies the specified object filter and notifies Git about the existence of promisor pack-files. Without a remote, that is currently impossible. As a stop-gap, parse the bundle header during 'git clone' and die() with a helpful error message instead of the current behavior of failing due to "missing objects". Most of the existing logic for handling bundle clones actually happens in fetch-pack.c, but that logic is the same as if the user specified 'git fetch <bundle>', so we want to avoid failing to fetch a filtered bundle when in an existing repository that has the proper config set up for at least one remote. Carefully comment around the test that this is not the desired long-term behavior of 'git clone' in this case, but instead that we need to do more work before that is possible.

In order to have a valid pack-file after unbundling a bundle that has the 'filter' capability, we need to generate a .promisor file.

Use the 'git index-pack --promisor=<message>' option to create this .promisor file. Add "from-bundle" as the message to help anyone diagnose issues with these promisor packs.

A previous change allowed Git to parse bundles with the 'filter' capability. Now, teach Git to create bundles with this option. Some rearranging of code is required to get the option parsing in the correct spot. There are now two reasons why we might need capabilities (a new hash algorithm or an object filter) so that is pulled out into a place where we can check both at the same time. The --filter option is parsed as part of setup_revisions(), but it expected the --objects flag, too. That flag is somewhat implied by 'git bundle' because it creates a pack-file walking objects, but there is also a walk that walks the revision range expecting only commits. Make this parsing work by setting 'revs.tree_objects' and 'revs.blob_objects' before the call to setup_revisions().

2022-03-09list-objects: handle NULL function pointersLibravatar Ævar Arnfjörð Bjarmason1-0/+12
If a caller to traverse_commit_list() specifies the options for the --objects flag but does not specify a show_object function pointer, the result is a segfault. This is currently visible by running 'git bundle create --objects HEAD'. We could fix this problem by supplying a no-op callback in builtin/bundle.c, but that only solves the problem for one builtin, leaving this segfault open for other callers. Replace all callers of the show_commit and show_object function pointers in list-objects.c to call helper functions show_commit() and show_object() which check that the given context has non-NULL functions before passing the necessary data. One extra benefit is that it reduces duplication due to passing ctx->show_data to every caller. Test that this segfault no longer occurs for 'git bundle'.

2022-03-09index-pack: document and test the --promisor optionLibravatar Derrick Stolee1-1/+3
The --promisor option of 'git index-pack' was created in 88e2f9e (introduce fetch-object: fetch one promisor object, 2017-12-05) but was untested. It is currently unused within the Git codebase, but that will change in an upcoming change to 'git bundle unbundle' when there is a filter capability. For now, add documentation about the option and add a test to ensure it is working as expected.

2022-03-08gitweb: remove invalid http-equiv="content-type"Libravatar Jason Yundt1-0/+13
Before this change, gitweb would generate pages which included: <meta http-equiv="content-type" content="application/xhtml+xml; charset=utf-8"/> When a meta's http-equiv equals "content-type", the http-equiv is said to be in the "Encoding declaration state". According to the HTML Standard, The Encoding declaration state may be used in HTML documents, but elements with an http-equiv attribute in that state must not be used in XML documents. Source: <https://html.spec.whatwg.org/multipage/semantics.html#attr-meta-http-equiv-content-type> This change removes that meta element since gitweb always generates XML documents.

2022-03-07t5526: create superproject commits with test helperLibravatar Glen Choo1-50/+45
A few tests in t5526 use this pattern as part of their setup: 1. Create new commits in the upstream submodules (using add_upstream_commit()). 2. In the upstream superprojects, add the new submodule commits from the previous step. A future commit will add more tests with this pattern, so reduce the verbosity of present and future tests by introducing a test helper that creates superproject commits. Since we now have two helpers that add upstream commits, rename add_upstream_commit() to add_submodule_commits().

2022-03-07t5526: stop asserting on stderr literallyLibravatar Glen Choo1-61/+56
In the previous commit message, we noted that not all of the "git fetch" stderr is relevant to the tests. Most of the test setup lines are dedicated to these details of the stderr: 1. which repos (super/sub/deep) are involved in the fetch 2. the head of the remote-tracking branch before the fetch (i.e. $head1) 3. the head of the remote-tracking branch after the fetch (i.e. $head2) 1. and 3. are relevant because they tell us that the expected commit is fetched by the expected repo, but 2. is completely irrelevant. Stop asserting on $head1 by replacing it with a dummy value in the actual and expected output. Do this by introducing test helpers (write_expected_*()) that make it easier to construct the expected output, and use sed to munge the actual output.

2022-03-07t5526: introduce test helper to assert on fetchesLibravatar Glen Choo1-55/+84
Tests in t/t5526-fetch-submodules.sh are unnecessarily noisy: * The tests have extra logic in order to reproduce the expected stderr literally, but not all of these details (e.g. the head of the remote-tracking branch before the fetch) are relevant to the test. * The expect.err file is constructed by the add_upstream_commit() helper as input into test_cmp, but most tests fetch a different combination of repos from expect.err. This results in noisy tests that modify parts of that expect.err to generate the expected output. To address both of these issues, introduce a verify_fetch_result() helper to t/t5526-fetch-submodules.sh that asserts on the output of "git fetch --recurse-submodules" and handles the ordering of expect.err. As a result, the tests no longer construct expect.err manually. Tests still consider the old head of the remote-tracking branch ("$head1"), but that will be fixed in a later commit.

2022-03-07rev-list simplify tests: don't ignore "git" exit codeLibravatar Ævar Arnfjörð Bjarmason1-5/+7
Change a fragile test pattern introduced in 65347030590 (Topo-sort before --simplify-merges, 2008-08-03) to check the exit code of both "git name-rev" and "git log". This test as a whole would fail under SANITIZE=leak, but we'd pass several "failing" tests due to hiding these exit codes before we'd spot git dying with abort(). Now we'll instead spot all of the failures. Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2022-03-07apply tests: don't ignore "git ls-files" exit code, drop sub-shellLibravatar Ævar Arnfjörð Bjarmason1-1/+2
Fix code added in 969c877506c (git apply --directory broken for new files, 2008-10-12) so that it doesn't invoke "git ls-files" on the left-hand-side of a pipe, instead let's use an intermediate file. Since we're doing that we can also drop the sub-shell that was here to group the two. There are a lot of these sorts of patterns in the test suite, and there's no particular reason to fix this one other than in a preceding commit all similar patterns except this one were fixed in "t/t4128-apply-root.sh", so let's fix this one straggler as well.
