2020-11-06tests: consolidate the `file_size` function into `test-lib-functions.sh`Libravatar Johannes Schindelin1-0/+4
In 8de7eeb54b6 (compression: unify pack.compression configuration parsing, 2016-11-15), we introduced identical copies of the `file_size` helper into three test scripts, with the plan to eventually consolidate them into a single copy. Let's do that, and adjust the function name to adhere to the `test_*` naming convention.

2020-09-17maintenance: create basic maintenance runnerLibravatar Derrick Stolee1-0/+33
The 'gc' builtin is our current entrypoint for automatically maintaining a repository. This one tool does many operations, such as repacking the repository, packing refs, and rewriting the commit-graph file. The name implies it performs "garbage collection" which means several different things, and some users may not want to use this operation that rewrites the entire object database. Create a new 'maintenance' builtin that will become a more general- purpose command. To start, it will only support the 'run' subcommand, but will later expand to add subcommands for scheduling maintenance in the background. For now, the 'maintenance' builtin is a thin shim over the 'gc' builtin. In fact, the only option is the '--auto' toggle, which is handed directly to the 'gc' builtin. The current change is isolated to this simple operation to prevent more interesting logic from being lost in all of the boilerplate of adding a new builtin. Use existing builtin/gc.c file because we want to share code between the two builtins. It is possible that we will have 'maintenance' replace the 'gc' builtin entirely at some point, leaving 'git gc' as an alias for some specific arguments to 'git maintenance run'. Create a new test_subcommand helper that allows us to test if a certain subcommand was run. It requires storing the GIT_TRACE2_EVENT logs in a file. A negation mode is available that will be used in later tests.

2020-08-13drop vcs-svn experimentLibravatar Jeff King1-1/+1
The code in vcs-svn was started in 2010 as an attempt to build a remote-helper for interacting with svn repositories (as opposed to git-svn). However, we never got as far as shipping a mature remote helper, and the last substantive commit was e99d012a6bc in 2012. We do have a git-remote-testsvn, and it is even installed as part of "make install". But given the name, it seems unlikely to be used by anybody (you'd have to explicitly "git clone testsvn::$url", and there have been zero mentions of that on the mailing list since 2013, and even that includes the phrase "you might need to hack a bit to get it working properly"[1]). We also ship contrib/svn-fe, which builds on the vcs-svn work. However, it does not seem to build out of the box for me, as the link step misses some required libraries for using libgit.a. Curiously, the original build breakage bisects for me to eff80a9fd9 (Allow custom "comment char", 2013-01-16), which seems unrelated. There was an attempt to fix it in da011cb0e7 (contrib/svn-fe: fix Makefile, 2014-08-28), but on my system that only switches the error message. So it seems like the result is not really usable by anybody in practice. It would be wonderful if somebody wanted to pick up the topic again, and potentially it's worth carrying around for that reason. But the flip side is that people doing tree-wide operations have to deal with this code. And you can see the list with (replace "HEAD" with this commit as appropriate): { echo "--" git diff-tree --diff-filter=D -r --name-only HEAD^ HEAD } | git log --no-merges --oneline e99d012a6bc.. --stdin which shows 58 times somebody had to deal with the code, generally due to a compile or test failure, or a tree-wide style fix or API change. Let's drop it and let anybody who wants to pick it up do so by resurrecting it from the git history. As a bonus, this also reduces the size of a stripped installation of Git from 21MB to 19MB.

2020-08-09test_cmp: diagnose incorrect argumentsLibravatar Eric Sunshine1-2/+14
Under normal circumstances, if a test author misspells a filename passed to test_cmp(), the error is quickly discovered when the test fails unexpectedly due to test_cmp() being unable to find the file. However, if the test is expected to fail, as with test_expect_failure(), a misspelled filename as argument to test_cmp() will go unnoticed since the test will indeed fail, but for the wrong reason. Make it easier for test authors to discover such problems early by sanity-checking the arguments to test_cmp(). To avoid penalizing all clients of test_cmp() in the general case, only check for missing files if the comparison fails. While at it, make test_cmp_bin() sanity-check its arguments, as well.

2020-07-30t: add test_oid option to select hash algorithmLibravatar brian m. carlson1-1/+11
In some tests, we have data files which are written with a particular hash algorithm. Instead of keeping two copies of the test files, we can keep one, and translate the value on the fly. In order to do so, we'll need to read both the source algorithm and the current algorithm, so add an optional flag to the test_oid helper that lets us look up a value for a specified hash algorithm. This should not cause any conflicts with existing tests, since key arguments to test_oid are allowed to contains only shell identifier characters.

2020-07-07test-lib-functions: restrict test_must_fail usageLibravatar Denton Liu1-0/+47
In previous commits, we removed the usage of test_must_fail() for most commands except for a set of pre-approved commands. Since that's done, only allow test_must_fail() to run those pre-approved commands. Obviously, we should allow `git`. We allow `__git*` as some completion functions return an error code that comes from a git invocation. It's good to avoid using test_must_fail unnecessarily but it wouldn't hurt to err on the side of caution when we're potentially wrapping a git command (like in these cases). We also allow `test-tool` and `test-svn-fe` because these are helper commands that are written by us and we want to catch their failure. Finally, we allow `test_terminal` because `test_terminal` just wraps around git commands. Also, we cannot rewrite `test_must_fail test_terminal` as `test_terminal test_must_fail` because test_must_fail() is a shell function and as a result, it cannot be invoked from the test-terminal Perl script. We opted to explicitly list the above tools instead of using a catch-all such as `test[-_]*` because we want to be as restrictive as possible so that in the future, someone would not accidentally introduce an unrelated usage of test_must_fail() on an "unapproved" command.

2020-03-29test-lib-functions: simplify packetize() stdin codeLibravatar Jeff King1-5/+4
The code path in packetize() for reading stdin needs to handle NUL bytes, so we can't rely on shell variables. However, the current code takes a whopping 4 processes and uses a temporary file. We can do this much more simply and efficiently by using a single perl invocation (and we already rely on perl in the matching depacketize() function).

2020-03-27test-lib-functions: make packetize() more efficientLibravatar Jeff King1-7/+16
The packetize() function takes its input on stdin, and requires 4 separate sub-processes to format a simple string. We can do much better by getting the length via the shell's "${#packet}" construct. The one caveat is that the shell can't put a NUL into a variable, so we'll have to continue to provide the stdin form for a few calls. There are a few other cleanups here in the touched code: - the stdin form of packetize() had an extra stray "%s" when printing the packet - the converted calls in t5562 can be made simpler by redirecting output as a block, rather than repeated appending Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2020-02-14t5310: factor out bitmap traversal comparisonLibravatar Jeff King1-0/+27
We check the results of "rev-list --use-bitmap-index" by comparing it to the same traversal without the bitmap option. However, this is a little tricky to do because of some output differences (see the included comment for details). Let's pull this out into a helper function, since we'll be adding some similar tests. While we're at it, let's also try to confirm that the bitmap output did indeed use bitmaps. Since the code internally falls back to the non-bitmap path in some cases, the tests are at risk of becoming trivial noops. This is a bit fragile, as not all outputs will differ (e.g., looking at only the commits from a fully-bitmapped pack will end up exactly the same as the normal traversal order, since it also matches the pack order). So we'll provide an escape hatch by which tests can disable this check (which should only be used after manually confirming that bitmaps kicked in).

When 'test_commit_bulk' is invoked in an empty test repository, it prints a "fatal: Needed a single revision" error, but still does what it's supposed to do. A test helper function displaying a fatal error and still succeeding is always suspect to be buggy, but luckily that's not the case here: that error comes from a 'git rev-parse --verify HEAD' command invoked in a condition, which doesn't have anything to verify in an empty repository.

2019-11-23tests: add 'test_bool_env' to catch non-bool GIT_TEST_* valuesLibravatar SZEDER Gábor1-1/+29
Since 3b072c577b (tests: replace test_tristate with "git env--helper", 2019-06-21) we get the normalized bool values of various GIT_TEST_* environment variables via 'git env--helper'. Now, while the 'git env--helper' command itself does catch invalid values in the environment variable or in the given --default and exits with error (exit code 128 or 129, respectively), it's invoked in conditions like 'if ! git env--helper ...', which means that all invalid bool values are interpreted the same as the ordinary 'false' (exit code 1). This has led to inadvertently skipped httpd tests in our CI builds for a couple of weeks, see 3960290675 (ci: restore running httpd tests, 2019-09-06). Let's be more careful about what the test suite accepts as bool values in GIT_TEST_* environment variables, and error out loud and clear on invalid values instead of simply skipping tests. Add the 'test_bool_env' helper function to encapsulate the invocation of 'git env--helper' and the verification of its exit code, and replace all invocations of that command in our test framework and test suite with a call to this new helper (except in 't0017-env-helper.sh', of course). $ GIT_TEST_GIT_DAEMON=YesPlease ./t5570-git-daemon.sh fatal: bad numeric config value 'YesPlease' for 'GIT_TEST_GIT_DAEMON': invalid unit error: test_bool_env requires bool values both for $GIT_TEST_GIT_DAEMON and for the default fallback Signed-off-by: SZEDER Gábor <szeder.dev@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-11-21t: teach test_cmp_rev to accept ! for not-equalsLibravatar Denton Liu1-4/+15
In the case where we are using test_cmp_rev() to report not-equals, we write `! test_cmp_rev`. However, since test_cmp_rev() contains r1=$(git rev-parse --verify "$1") && r2=$(git rev-parse --verify "$2") && `! test_cmp_rev` will succeed if any of the rev-parses fail. This behavior is not desired. We want the rev-parses to _always_ be successful. Rewrite test_cmp_rev() to optionally accept "!" as the first argument to do a not-equals comparison. Rewrite `! test_cmp_rev` to `test_cmp_rev !` in all tests to take advantage of this new functionality. Also, rewrite the rev-parse logic to end with a `|| return 1` instead of &&-chaining into the rev-comparison logic. This makes it obvious to future readers that we explicitly intend on returning early if either of the rev-parses fail.

With '-x' tracing enabled and/or in longer tests the verbose output might be several screenfulls long, making it harder than necessary to find where the output of the test with a given name starts (especially when the outputs to different file descriptors are racing, and the "expecting success"/command block arrives earlier than the "ok" line of the previous test). Print the test name at the start of the test's verbose output, i.e. at the end of the "expecting success" and "checking known breakage" lines, to make the start of a particular test a bit easier to recognize.

2019-07-02test-lib: introduce test_commit_bulkLibravatar Jeff King1-0/+123
Some tests need to create a string of commits. Doing this with test_commit is very heavy-weight, as it needs at least one process per commit (and in fact, uses several). For bulk creation, we can do much better by using fast-import, but it's often a pain to generate the input. Let's provide a helper to do so. We'll use t5310 as a guinea pig, as it has three 10-commit loops. Here are hyperfine results before and after: [before] Benchmark #1: ./t5310-pack-bitmaps.sh --root=/var/ram/git-tests Time (mean ± σ): 2.846 s ± 0.305 s [User: 3.042 s, System: 0.919 s] Range (min … max): 2.250 s … 3.210 s 10 runs [after] Benchmark #1: ./t5310-pack-bitmaps.sh --root=/var/ram/git-tests Time (mean ± σ): 2.210 s ± 0.174 s [User: 2.570 s, System: 0.604 s] Range (min … max): 1.999 s … 2.590 s 10 runs So we're over 20% faster, while making the callers slightly shorter. We added a lot more lines in test-lib-function.sh, of course, and the helper is way more featureful than we need here. But my hope is that it will be flexible enough to use in more places.

2019-07-01t: add helper to convert object IDs to pathsLibravatar brian m. carlson1-0/+6
There are several places in our testsuite where we want to insert a slash after an object ID to make it into a path we can reference under .git/objects, and we have various ways of doing so.

2019-06-24t0001: fix on case-insensitive filesystemsLibravatar Johannes Schindelin1-0/+15
On a case-insensitive filesystem, such as HFS+ or NTFS, it is possible that the idea Bash has of the current directory differs in case from what Git thinks it is. That's totally okay, though, and we should not expect otherwise. On Windows, for example, when you call cd C:\GIT-SDK-64 in a PowerShell and there exists a directory called `C:\git-sdk-64`, the current directory will be reported in all upper-case. Even in a Bash that you might call from that PowerShell. Git, however, will have normalized this via `GetFinalPathByHandle()`, and the expectation in t0001 that the recorded gitdir will match what `pwd` says will be violated. Let's address this by comparing these paths in a case-insensitive manner when `core.ignoreCase` is `true`. Reported by Jameson Miller.

2019-06-21tests: make GIT_TEST_FAIL_PREREQS a booleanLibravatar Ævar Arnfjörð Bjarmason1-2/+2
Change the GIT_TEST_FAIL_PREREQS variable from being "non-empty?" to being a more standard boolean variable. I recently added the variable in dfe1a17df9 ("tests: add a special setup where prerequisites fail", 2019-05-13), having to add another "non-empty?" special-case is what prompted me to write the "git env--helper" utility being used here. Converting this one is a bit tricky since we use it so early and frequently in the guts of the test code itself, so let's set a GIT_TEST_FAIL_PREREQS_INTERNAL which can be tested with the old "test -n" for the purposes of the shell code, and change the user-exposed and documented GIT_TEST_FAIL_PREREQS variable to a boolean.

2019-06-21tests: replace test_tristate with "git env--helper"Libravatar Ævar Arnfjörð Bjarmason1-49/+7
The test_tristate helper introduced in 83d842dc8c ("tests: turn on network daemon tests by default", 2014-02-10) can now be better implemented with "git env--helper" to give the variables in question the standard boolean behavior. The reason for the "tristate" was to have all of false/true/auto, where "auto" meant either "false" or "true" depending on what the fallback was. With the --default option to "git env--helper" we can simply have e.g. GIT_TEST_HTTPD where we know if it's true because the user asked explicitly ("true"), or true implicitly ("auto"). This breaks backwards compatibility for explicitly setting "auto" for these variables, but I don't think anyone cares. That was always intended to be internal. This means the test_normalize_bool() code in test-lib-functions.sh goes away in addition to test_tristate(). We still need the test_skip_or_die() helper, but now it takes the variable name instead of the value, and uses "git env--bool" to distinguish a default "true" from an explicit "true" (in those "explicit true" cases we want to fail the test in question).

2019-05-14tests: add a special setup where prerequisites failLibravatar Ævar Arnfjörð Bjarmason1-0/+20
As discussed in [1] there's a regression in the "pu" branch now because a new test implicitly assumed that a previous test guarded by a prerequisite had been run. Add a "GIT_TEST_FAIL_PREREQS" special test setup where we'll skip (nearly) all tests guarded by prerequisites, allowing us to easily emulate those platform where we don't run these tests. As noted in the documentation I'm adding I'm whitelisting the SYMLINKS prerequisite for now. A lot of tests started failing if we lied about not supporting symlinks. It's also unlikely that we'll have a failing test due to a hard dependency on symlinks without that being the obvious cause, so for now it's not worth the effort to make it work. 1. https://public-inbox.org/git/nycvar.QRO.7.76.6.1905131531000.44@tvgsbejvaqbjf.bet/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2019-04-05t: move 'hex2oct' into test-lib-functions.shLibravatar Taylor Blau1-0/+6
The helper 'hex2oct' is used to convert base-16 encoded data into a base-8 binary form, and is useful for preparing data for commands that accept input in a binary format, such as 'git hash-object', via 'printf'. This helper is defined identically in three separate places throughout 't'. Move the definition to test-lib-function.sh, so that it can be used in new test suites, and its definition is not redundant. This will likewise make our job easier in the subsequent commit, which also uses 'hex2oct'. Signed-off-by: Taylor Blau <me@ttaylorr.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-03-14test-lib: introduce 'test_atexit'Libravatar Johannes Schindelin1-0/+28
When running Apache, 'git daemon', or p4d, we want to kill them at the end of the test script, otherwise a leftover daemon process will keep its port open indefinitely, and thus will interfere with subsequent executions of the same test script. So far, we stop these daemon processes "manually", i.e.: - by registering functions or commands in the trap on EXIT to stop the daemon while preserving the last seen exit code before the trap (to deal with a failure when run with '--immediate' or with interrupts by ctrl-C), - and by invoking these functions/commands last thing before 'test_done' (and sometimes restoring the test framework's default trap on EXIT, to prevent the daemons from being killed twice). On one hand, we do this inconsistently, e.g. 'git p4' tests invoke different functions in the trap on EXIT and in the last test before 'test_done', and they neither restore the test framework's default trap on EXIT nor preserve the last seen exit code. On the other hand, this is error prone, because, as shown in a previous patch in this series, any output from the cleanup commands in the trap on EXIT can prevent a proper cleanup when a test script run with '--verbose-log' and certain shells, notably 'dash', is interrupted. Let's introduce 'test_atexit', which is loosely modeled after 'test_when_finished', but has a broader scope: rather than running the commands after the current test case, run them when the test script finishes, and also run them when the test is interrupted, or exits early in case of a failure while the '--immediate' option is in effect. When running the cleanup commands at the end of a successful test, then they will be run in 'test_done' before it removes the trash directory, i.e. the cleanup commands will still be able to access any pidfiles or socket files in there. When running the cleanup commands after an interrupt or failure with '--immediate', then they will be run in the trap on EXIT. In both cases they will be run in 'test_eval_', i.e. both standard error and output of all cleanup commands will go where they should according to the '-v' or '--verbose-log' options, and thus won't cause any troubles when interrupting a test script run with '--verbose-log'.

2019-02-19tests: teach the test-tool to generate NUL bytes and use itLibravatar Johannes Schindelin1-7/+1
In cc95bc2025 (t5562: replace /dev/zero with a pipe from generate_zero_bytes, 2019-02-09), we replaced usage of /dev/zero (which is not available on NonStop, apparently) by a Perl script snippet to generate NUL bytes. Sadly, it does not seem to work on NonStop, as t5562 reportedly hangs. Worse, this also hangs in the Ubuntu 16.04 agents of the CI builds on Azure Pipelines: for some reason, the Perl script snippet that is run via `generate_zero_bytes` in t5562's 'CONTENT_LENGTH overflow ssite_t' test case tries to write out an infinite amount of NUL bytes unless a broken pipe is encountered, that snippet never encounters the broken pipe, and keeps going until the build times out. Oddly enough, this does not reproduce on the Windows and macOS agents, nor in a local Ubuntu 18.04. This developer tried for a day to figure out the exact circumstances under which this hang happens, to no avail, the details remain a mystery. In the end, though, what counts is that this here change incidentally fixes that hang (maybe also on NonStop?). Even more positively, it gets rid of yet another unnecessary Perl invocation.

2019-02-11test-lib: fix non-portable pattern bracket expressionsLibravatar SZEDER Gábor1-1/+1
Use a '!' character to start a non-matching pattern bracket expression, as specified by POSIX in Shell Command Language section 2.13.1 Patterns Matching a Single Character [1]. I used '^' instead in three places in the previous three commits, to verify that the arguments of the '--stress=' and '--stress-limit=' options and the values of various '*_PORT' environment variables are valid numbers. With certain shells, at least with dash (upstream and in Ubuntu 14.04) and mksh, this led to various undesired behaviors: # error message in case of a valid number $ ~/src/dash/src/dash ./t3903-stash.sh --stress=8 error: --stress=<N> requires the number of jobs to run # not the expected error message $ ~/src/dash/src/dash ./t3903-stash.sh --stress=foo ./t3903-stash.sh: 238: test: Illegal number: foo # no error message at all?! $ mksh ./t3903-stash.sh --stress=foo $ echo $? 0 Some other shells, e.g. Bash (even in posix mode), ksh, dash in Ubuntu 16.04 or later, are apparently happy to accept '^' just as well.
