2020-07-07test-lib-functions: restrict test_must_fail usageLibravatar Denton Liu1-0/+18
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.

2020-04-28t0000: disable GIT_TEST_FAIL_PREREQS in sub-testsLibravatar Jeff King1-0/+1
The test added by 477dcaddb6 (tests: do not let lazy prereqs inside `test_expect_*` turn off tracing, 2020-03-26) runs a sub-test script that traces a test with a lazy prereq, like: test_have_prereq LAZY && echo trace That won't work if GIT_TEST_FAIL_PREREQS is set in the environment, because our have_prereq will report failure, and we won't run the echo at all. We could work around this by avoiding the &&-chain, but we can fix this and any future tests at once by unsetting that variable for our sub-tests. These are meant to be controlled environments where we test the test-suite itself; the outer test snippet should be in charge of the sub-test environment, not whatever mode the user happens to be running in.

2020-03-26tests: do not let lazy prereqs inside `test_expect_*` turn off tracingLibravatar Johannes Schindelin1-0/+13
The `test_expect_*` functions use `test_eval_` and so does `test_run_lazy_prereq_`. If tracing is enabled via the `-x` option, `test_eval_` turns on tracing while evaluating the code block, and turns it off directly after it. This is unwanted for nested invocations. One somewhat surprising example of this is when running a test that calls `test_i18ngrep`: that function requires the `C_LOCALE_OUTPUT` prereq, and that prereq is a lazy one, so it is evaluated via `test_eval_`, the command tracing is turned off, and the test case continues to run _without tracing the commands_. Another somewhat surprising example is when one lazy prereq depends on another lazy prereq: the former will call `test_have_prereq` with the latter one, which in turn calls `test_eval_` and -- you guessed it -- tracing (if enabled) will be turned off _before_ returning to evaluating the other lazy prereq. As we will introduce just such a scenario with the GPG, GPGSM and RFC1991 prereqs, let's fix that by introducing a variable that keeps track of the current trace level: nested `test_eval_` calls will increment and then decrement the level, and only when it reaches 0, the tracing will _actually_ be turned off.

The test_must_fail function should only be used for git commands since we should assume that external commands work sanely. We use test_must_fail to test run_sub_test_lib_test() but that function does not invoke any git commands internally.

2019-11-23tests: add 'test_bool_env' to catch non-bool GIT_TEST_* valuesLibravatar SZEDER Gábor1-0/+34
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>
2019-11-21t0000: test multiple local assignmentLibravatar Denton Liu1-7/+8
According to POSIX enhancement request '0000767: Add built-in "local"'[1], dash only allows one variable in a local definition; it permits assignment though it doesn't document that clearly. however, this isn't true since t0000 still passes with this patch applied on dash 0.5.10.2. Needless to say, since `local` isn't POSIX standardized, it is not exactly clear what `local` entails on different versions of different shells. We currently already have many instances of multiple local assignments in our codebase. Ensure that this is actually supported by explicitly testing that it is sane.

The verbose output of every test looks something like this: expecting success: echo content >file && git add file && git commit -m "add file" [master (root-commit) d1fbfbd] add file Author: A U Thor <author@example.com> 1 file changed, 1 insertion(+) create mode 100644 file ok 1 - commit works i.e. first an "expecting success" (or "checking known breakage") line followed by the commands to be executed, then the output of those comamnds, and finally an "ok"/"not ok" line containing the test name. Note that the test's name is only shown at the very end. 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. Also print the test script and test case numbers, to help those poor souls who regularly have to scan through the combined verbose output of several test scripts.

2019-08-05t0000-basic: use realistic test script names in the verbose testsLibravatar SZEDER Gábor1-6/+6
Our test scripts are named something like 't1234-command.sh', but the script names used in 't0000-basic.sh' don't follow this naming convention. Normally this doesn't matter, because the test scripts themselves don't care how they are called. However, the next patch will start to include the test number in the test's verbose output, so the test script's name will matter in the two tests checking the verbose output. Update the tests 'test --verbose' and 'test --verbose-only' to follow out test script naming convention. Leave the other tests in 't0000' unchanged: changing the names of their test scripts would be only pointless code churn.

2019-06-21tests: make GIT_TEST_FAIL_PREREQS a booleanLibravatar Ævar Arnfjörð Bjarmason1-5/+5
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.

2019-05-14tests: add a special setup where prerequisites failLibravatar Ævar Arnfjörð Bjarmason1-5/+5
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>
2019-03-14test-lib: introduce 'test_atexit'Libravatar Johannes Schindelin1-0/+18
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'.

2018-11-09i18n: make GETTEXT_POISON a runtime optionLibravatar Ævar Arnfjörð Bjarmason1-1/+1
Change the GETTEXT_POISON compile-time + runtime GIT_GETTEXT_POISON test parameter to only be a GIT_TEST_GETTEXT_POISON=<non-empty?> runtime parameter, to be consistent with other parameters documented in "Running tests with special setups" in t/README. When I added GETTEXT_POISON in bb946bba76 ("i18n: add GETTEXT_POISON to simulate unfriendly translator", 2011-02-22) I was concerned with ensuring that the _() function would get constant folded if NO_GETTEXT was defined, and likewise that GETTEXT_POISON would be compiled out unless it was defined. But as the benchmark in my [1] shows doing a one-off runtime getenv("GIT_TEST_[...]") is trivial, and since GETTEXT_POISON was originally added the GIT_TEST_* env variables have become the common idiom for turning on special test setups. So change GETTEXT_POISON to work the same way. Now the GETTEXT_POISON=YesPlease compile-time option is gone, and running the tests with GIT_TEST_GETTEXT_POISON=[YesPlease|] can be toggled on/off without recompiling. This allows for conditionally amending tests to test with/without poison, similar to what 859fdc0c3c ("commit-graph: define GIT_TEST_COMMIT_GRAPH", 2018-08-29) did for GIT_TEST_COMMIT_GRAPH. Do some of that, now we e.g. always run the t0205-gettext-poison.sh test. I did enough there to remove the GETTEXT_POISON prerequisite, but its inverse C_LOCALE_OUTPUT is still around, and surely some tests using it can be converted to e.g. always set GIT_TEST_GETTEXT_POISON=. Notes on the implementation: * We still compile a dedicated GETTEXT_POISON build in Travis CI. Perhaps this should be revisited and integrated into the "linux-gcc" build, see ae59a4e44f ("travis: run tests with GIT_TEST_SPLIT_INDEX", 2018-01-07) for prior art in that area. Then again maybe not, see [2]. * We now skip a test in t0000-basic.sh under GIT_TEST_GETTEXT_POISON=YesPlease that wasn't skipped before. This test relies on C locale output, but due to an edge case in how the previous implementation of GETTEXT_POISON worked (reading it from GIT-BUILD-OPTIONS) wasn't enabling poison correctly. Now it does, and needs to be skipped. * The getenv() function is not reentrant, so out of paranoia about code of the form: printf(_("%s"), getenv("some-env")); call use_gettext_poison() in our early setup in git_setup_gettext() so we populate the "poison_requested" variable in a codepath that's won't suffer from that race condition. * We error out in the Makefile if you're still saying GETTEXT_POISON=YesPlease to prompt users to change their invocation. * We should not print out poisoned messages during the test initialization itself to keep it more readable, so the test library hides the variable if set in $GIT_TEST_GETTEXT_POISON_ORIG during setup. See [3]. See also [4] for more on the motivation behind this patch, and the history of the GETTEXT_POISON facility. 1. https://public-inbox.org/git/871s8gd32p.fsf@evledraar.gmail.com/ 2. https://public-inbox.org/git/20181102163725.GY30222@szeder.dev/ 3. https://public-inbox.org/git/20181022202241.18629-2-szeder.dev@gmail.com/ 4. https://public-inbox.org/git/878t2pd6yu.fsf@evledraar.gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-09-28t0000: do not get self-test disrupted by environment warningsLibravatar Junio C Hamano1-0/+4
The test framework test-lib.sh itself would want to give warnings and hints, e.g. when it sees a deprecated environment variable is in use that we want to encourage users to migrate to another variable. The self-test of test framework done in t0000 however do not expect to see these warnings and hints, so depending on the settings of environment variables, a running test may or may not produce these messages to the standard error output, breaking the expectations of self-test test framework does on itself. Here is what we see: $ TEST_GIT_INDEX_VERSION=4 sh t0000-basic.sh -i -v ... 'err' is not empty, it contains: warning: TEST_GIT_INDEX_VERSION is now GIT_TEST_INDEX_VERSION hint: set GIT_TEST_INDEX_VERSION too during the transition period not ok 5 - pretend we have a fully passing test suite The following quick attempt to work it around does not work, because some tests in t0000 do want to see expected errors from the test framework itself. t/t0000-basic.sh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/t/t0000-basic.sh b/t/t0000-basic.sh index 850f651e4e..88c6ed4696 100755 --- a/t/t0000-basic.sh +++ b/t/t0000-basic.sh @@ -88,7 +88,7 @@ _run_sub_test_lib_test_common () { ' # Point to the t/test-lib.sh, which isn't in ../ as usual - .

The final patch I came up with is probably the solution that is least bad. Set a variable to tell test-lib.sh that we are running a self-test, so that various pieces in test-lib.sh can react to keep the output stable. Signed-off-by: Junio C Hamano <gitster@pobox.com>

Document this format in a t/oid-info/README directory so that it's easier to use in the future. Add test_oid, which is used to specify look up a per-hash value (produced on standard output) based on the key specified as its argument. Usually the data to be looked up will be a hash-related constant (such as the size of the hash in binary or hexadecimal), a well-known or placeholder object ID (such as the all-zeros object ID or one consisting of "deadbeef" repeated), or something similar. For these reasons, test_oid will usually be used within a command substitution. Consequently, redirect the error output to standard error, since otherwise it will not be displayed. Add test_detect_hash, which currently only detects SHA-1, and test_set_hash, which can be used to set a different hash algorithm for test purposes. In the future, test_detect_hash will learn to actually detect the hash depending on how the testsuite is to be run. Use the local keyword within these functions to avoid overwriting other shell variables. We have had a test balloon in place for a couple of releases to catch shells that don't have this keyword and have not received any reports of failure. Note that the varying usages of local used here are supported by all common open-source shells supporting the local keyword. Test these new functions as part of t0000, which also serves to demonstrate basic usage of them. In addition, add documentation on how to format the lookup data and how to use the test functions. Implement two basic lookup charts, one for common invalid or synthesized object IDs, and one for various facts about the hash function in use. Provide versions of the data for both SHA-1 and SHA-256. Since we use shell variables for storage, names used for lookup can currently consist only of shell identifier characters. If this is a problem in the future, we can hash the names before use.

2018-08-21tests: use 'test_must_be_empty' instead of '! test -s'Libravatar SZEDER Gábor1-1/+1
Using 'test_must_be_empty' is preferable to '! test -s', because it gives a helpful error message if the given file is unexpectedly not empty, while the latter remains completely silent. Furthermore, it also catches cases when the given file unexpectedly does not exist at all. This patch was basically created by: sed -i -e 's/! test -s/test_must_be_empty/' t[0-9]*.sh with the following notable exceptions: - The '! test -s' check in '.gitmodules ignore=dirty suppresses submodules with untracked content' in 't7508-status.sh' is left as-is, because it's bogus and, therefore, it's subject of a dedicated patch. - The '! test -s' checks in 't9131-git-svn-empty-symlink.sh' and 't9135-git-svn-moved-branch-empty-file.sh' are immediately preceeded by a 'test -f' to ensure that the files exist in the first place. 'test_must_be_empty' ensures that as well, so those 'test -f' commands are removed as well. Signed-off-by: SZEDER Gábor <szeder.dev@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-01-02t0000: drop "known breakage" testLibravatar Jeff King1-3/+0
Having a simulated "known breakage" test means that the test suite will always tell us there is a bug to be fixed, even though it is only simulated. The right way to test this is in a sub-test, that can also check that we provide the correct exit status and output. Fortunately, we already have such a test (added much later by 5ebf89e). We could arguably get rid of the simulated success test immediately above, as well, as it is also redundant with the tests added in 5ebf89e. However, it does not have the annoying behavior of the "known breakage" test. It may also be easier to debug if the test suite is truly broken, since it is not a test-within-a-test, as the later tests are.

2014-01-02t0000: simplify HARNESS_ACTIVE hackLibravatar Jeff King1-9/+5
Commit 517cd55 set HARNESS_ACTIVE unconditionally in sub-tests, because that value affects the output of "--verbose". t0000 needs stable output from its sub-tests, and we may or may not be running under a TAP harness. That commit made the decision to always set the variable, since it has another useful side effect, which is suppressing writes to t/test-results by the sub-tests (which would just pollute the real results). Since the last commit, though, the sub-tests have their own test-results directories, so this is no longer an issue. We can now update a few comments that are no longer accurate nor necessary. We can also revisit the choice of HARNESS_ACTIVE. Since we must choose one value for stability, it's probably saner to have it off. This means that future patches could test things like the test-results writing, or the "--quiet" option, which is currently ignored when run under a harness.

2014-01-02t0000: set TEST_OUTPUT_DIRECTORY for sub-testsLibravatar Jeff King1-0/+2
Running t0000 produces more trash directories than expected and does not clean up after itself: $ ./t0000-basic.sh [...] $ ls -d trash\ directory.* trash directory.failing-cleanup trash directory.mixed-results1 trash directory.mixed-results2 trash directory.partial-pass trash directory.test-verbose trash directory.test-verbose-only-2 These scratch areas for sub-tests should be under the t0000 trash directory, but because TEST_OUTPUT_DIRECTORY defaults to TEST_DIRECTORY, which is exported to help sub-tests find test-lib.sh, the sub-test trash directories are created under the toplevel t/ directory instead. Because some of the sub-tests simulate failures, their trash directories are kept around. Fix it by explicitly setting TEST_OUTPUT_DIRECTORY appropriately for sub-tests. An alternative fix would be to pass the --root parameter that only specifies where to put the trash directories, which would also work. However, using TEST_OUTPUT_DIRECTORY is more futureproof in case tests want to write more output in addition to the test-results/ (which are already suppressed in sub-tests using the HARNESS_ACTIVE setting) and trash directories. This fixes a regression introduced by 38b074d (t/test-lib.sh: fix TRASH_DIRECTORY handling, 2013-04-14). Before that commit, the TEST_OUTPUT_DIRECTORY setting was not respected consistently so most tests did their work in a "trash" subdirectory of the current directory instead of the output dir.

2013-06-23test-lib: verbose mode for only tests matching a patternLibravatar Thomas Rast1-0/+24
With the new --verbose-only=<pattern> option, one can enable --verbose at a per-test granularity. The pattern is matched against the test number, e.g. ./t0000-basic.sh --verbose-only='2[0-2]' to see only the full output of test 20-22, while showing the rest in the one-liner format. As suggested by Jeff King, this takes care to wrap the entire test_expect_* block, but nothing else, in the verbose toggling. We can use the test_start/end functions from the previous commit for the purpose. This is arguably not *too* useful on its own, but makes the next patch easier to follow.

2013-06-23test-lib: self-test that --verbose worksLibravatar Thomas Rast1-1/+36
t0000 contains some light self-tests of test-lib.sh, but --verbose was not covered. Add a test. The only catch is that the presence of a test harness influences the output (specifically, the presence of some empty lines). So we need to unset TEST_HARNESS or set it to a known value. Leaving it unset leads to spurious test failures in the final summary, which come from the subtest. So we always set it.

2013-06-07t0000: use test_ln_s_add to remove SYMLINKS prerequisiteLibravatar Johannes Sixt1-29/+10
t0000-basic hard-codes many object IDs. To cater to file systems that do not support symbolic links, different IDs are used depending on the SYMLINKS prerequisite. But we can observe the symbolic links are only needed to generate index entries. Use test_ln_s_add to generate the index entries and get rid of explicit SYMLINKS checks. This undoes the special casing introduced in this test by 704a3143 (Use prerequisite tags to skip tests that depend on symbolic links, 2009-03-04).
