Cygwin pathname handling fix. * ad/cygwin-no-backslashes-in-paths: cygwin: disallow backslashes in file names
10 dayscygwin: disallow backslashes in file namesAdam Dinwoodie
The backslash character is not a valid part of a file name on Windows. If, in Windows, Git attempts to write a file that has a backslash character in the filename, it will be incorrectly interpreted as a directory separator. This caused CVE-2019-1354 in MinGW, as this behaviour can be manipulated to cause the checkout to write to files it ought not write to, such as adding code to the .git/hooks directory. This was fixed by e1d911dd4c (mingw: disallow backslash characters in tree objects' file names, 2019-09-12). However, the vulnerability also exists in Cygwin: while Cygwin mostly provides a POSIX-like path system, it will still interpret a backslash as a directory separator. To avoid this vulnerability, CVE-2021-29468, extend the previous fix to also apply to Cygwin. Similarly, extend the test case added by the previous version of the commit. The test suite doesn't have an easy way to say "run this test if in MinGW or Cygwin", so add a new test prerequisite that covers both. As well as checking behaviour in the presence of paths containing backslashes, the existing test also checks behaviour in the presence of paths that differ only by the presence of a trailing ".". MinGW follows normal Windows application behaviour and treats them as the same path, but Cygwin more closely emulates *nix systems (at the expense of compatibility with native Windows applications) and will create and distinguish between such paths. Gate the relevant bit of that test accordingly.

2021-01-27test-lib: prevent '--stress-jobs=X' from being ignoredSZEDER Gábor
'./t1234-foo.sh --stress-jobs=X ...' is supposed to run that test script in X parallel jobs, but the number of jobs specified on the command line is entirely ignored if other '--stress'-related options follow. I.e. both './t1234-foo.sh --stress-jobs=X --stress-limit=Y' and './t1234-foo.sh --stress-jobs=X --stress' fall back to using twice the number of CPUs parallel jobs instead. The former has been broken since commit de69e6f6c9 (tests: let --stress-limit=<N> imply --stress, 2019-03-03) [1], which started to unconditionally overwrite the $stress variable holding the specified number of jobs in its effort to imply '--stress'. The latter has been broken since f545737144 (tests: introduce --stress-jobs=<N>, 2019-03-03), because it didn't consider that handling '--stress' will overwrite that variable as well. We could fix this by being more careful about (over)writing that $stress variable and checking first whether it has already been set. But I think it's cleaner to use a dedicated variable to hold the number of specified parallel jobs, so let's do that instead. [1] In de69e6f6c9 there was no '--stress-jobs=X' option yet, the number of parallel jobs had to be specified via '--stress=X', so, strictly speaking, de69e6f6c9 broke './t1234-foo.sh --stress=X --stress-limit=Y'.

With this the LIBPCRE2 test prerequisites is redundant to PCRE. But I'm keeping it for self-documentation purposes, and to avoid conflict with other in-flight PCRE patches. I'm also not changing all of our own "pcre2" names to "pcre", i.e. the inverse of 6d4b5747f0 (grep: change internal *pcre* variable & function names to be *pcre1*, 2017-05-25).

2021-01-21tests: remove support for GIT_TEST_GETTEXT_POISONÆvar Arnfjörð Bjarmason
This removes the ability to inject "poison" gettext() messages via the GIT_TEST_GETTEXT_POISON special test setup. I initially added this as a compile-time option in bb946bba761 (i18n: add GETTEXT_POISON to simulate unfriendly translator, 2011-02-22), and most recently modified to be toggleable at runtime in 6cdccfce1e0 (i18n: make GETTEXT_POISON a runtime option, 2018-11-08).. The reason for its removal is that the trade-off of maintaining it v.s. what it's getting us has long since flipped. When gettext was integrated in 5e9637c6297 (i18n: add infrastructure for translating Git with gettext, 2011-11-18) there was understandable concern on the Git ML that in marking messages for translation en-masse we'd inadvertently mark plumbing messages. The GETTEXT_POISON facility was a way to smoke those out via our test suite. Nowadays however we're done (or almost entirely done) with any marking of messages for translation. New messages are usually marked by their authors, who'll know whether it makes sense to translate them or not. If not any errors in marking the messages are much more likely to be spotted in review than in the the initial deluge of i18n patches in the 2011-2012 era. So let's just remove this. This leaves the test suite in a state where we still have a lot of test_i18n, C_LOCALE_OUTPUT etc. uses. Subsequent commits will remove those too. The change to t/lib-rebase.sh is a selective revert of the relevant part of f2d17068fd (i18n: rebase-interactive: mark comments of squash for translation, 2016-06-17), and the comment in t/t3406-rebase-message.sh is from c7108bf9ed (i18n: rebase: mark messages for translation, 2012-07-25).

2020-11-24maintenance: extract platform-specific schedulingDerrick Stolee
The existing schedule mechanism using 'cron' is supported by POSIX platforms, but not Windows. It also works slightly differently on macOS to significant detriment of the user experience. To allow for new implementations on these platforms, extract a method that performs the platform-specific scheduling mechanism. This will be swapped at compile time with new implementations on specialized platforms. As we add this generality, rename GIT_TEST_CRONTAB to GIT_TEST_MAINT_SCHEDULER. Further, this variable is now parsed as "<scheduler>:<command>" so we can test platform-specific scheduling logic even when not on the correct platform. By specifying the <scheduler> in this string, we will be able to test all three sets of Git logic from a Linux machine.

2020-10-23tests: start moving to a different default main branch nameJohannes Schindelin
To allow for an incremental conversion to a new default main branch name, let's introduce `GIT_TEST_DEFAULT_MAIN_BRANCH_NAME`. This environment variable can be set at the top of each converted test script, overriding the default main branch name to use when initializing new repositories (or cloning empty repositories). Note: the `GIT_TEST_DEFAULT_MAIN_BRANCH_NAME` is _not_ intended to be used manually; many tests require a specific main branch name and cannot simply work with another one. This `GIT_TEST_*` variable is meant purely for the transitional period while the entire test suite is converted to use `main` as the initial branch name by default. We also introduce the `PREPARE_FOR_MAIN_BRANCH` prereq that determines whether the default main branch name is `main`, and adjust a couple of test functions to use it. This prereq will be used to temporarily disable a couple test cases to allow for adjusting the test script incrementally. Once an entire test is adjusted, we will adjust the test so that it is run with `GIT_TEST_DEFAULT_MAIN_BRANCH_NAME=main`.

2020-10-22perl: check for perl warnings while running testsJeff King
We set "use warnings" in most of our perl code to catch problems. But as the name implies, warnings just emit a message to stderr and don't otherwise affect the program. So our tests are quite likely to miss that warnings are being spewed, as most of them do not look at stderr. We could ask perl to make all warnings fatal, but this is likely annoying for non-developers, who would rather have a running program with a warning than something that refuses to work at all. So instead, let's teach the perl code to respect an environment variable (GIT_PERL_FATAL_WARNINGS) to increase the severity of the warnings. This can be set for day-to-day running if people want to be really pedantic, but the primary use is to trigger it within the test suite. We could also trigger that for every test run, but likewise even the tests failing may be annoying to distro builders, etc (just as -Werror would be for compiling C code). So we'll tie it to a special test-mode variable (GIT_TEST_PERL_FATAL_WARNINGS) that can be set in the environment or as a Makefile knob, and we'll automatically turn the knob when DEVELOPER=1 is set. That should give developers and CI the more careful view without disrupting normal users or packagers. Note that the mapping from the GIT_TEST_* form to the GIT_* form in test-lib.sh is necessary even if they had the same name: the perl scripts need it to be normalized to a perl truth value, and we also have to make sure it's exported (we might have gotten it from the environment, but we might also have gotten it from GIT-BUILD-OPTIONS directly).

When using the --run flag to run just two or three tests from a test file which contains several dozen tests, having every skipped test print out dozens of lines of output for the test code for that skipped test (in addition to the TAP output line) adds up to hundreds or thousands of lines of irrelevant output that make it very hard to fish out the relevant results you were looking for. Simplify the output for skipped tests to remove this extra output, leaving only the TAP output line (i.e. the line reading "ok <number> # skip <test-description>", which already mentions that the test was "skip"ped).

Many of our test scripts have several "setup" tests. It's a lot easier to say ./t0050-filesystem.sh --run=setup,9 in order to run all the setup tests as well as test #9, than it is to track down what all the setup tests are and enter all their numbers in the list. Also, I often find myself wanting to run just one or a couple tests from the test file, but I don't know the numbering of any of the tests -- to get it I either have to first run the whole test file (or start counting by hand or figure out some other clever but non-obvious tricks). It's really convenient to be able to just look at the test description(s) and then run ./t6416-recursive-corner-cases.sh --run=symlink or ./t6402-merge-rename.sh --run='setup,unnecessary update' Add such an ability to test selection which relies on merely matching against the test description.

2020-09-25maintenance: add start/stop subcommandsDerrick Stolee
Add new subcommands to 'git maintenance' that start or stop background maintenance using 'cron', when available. This integration is as simple as I could make it, barring some implementation complications. The schedule is laid out as follows: 0 1-23 * * * $cmd maintenance run --schedule=hourly 0 0 * * 1-6 $cmd maintenance run --schedule=daily 0 0 * * 0 $cmd maintenance run --schedule=weekly where $cmd is a properly-qualified 'git for-each-repo' execution: $cmd=$path/git --exec-path=$path for-each-repo --config=maintenance.repo where $path points to the location of the Git executable running 'git maintenance start'. This is critical for systems with multiple versions of Git. Specifically, macOS has a system version at '/usr/bin/git' while the version that users can install resides at '/usr/local/bin/git' (symlinked to '/usr/local/libexec/git-core/git'). This will also use your locally-built version if you build and run this in your development environment without installing first. This conditional schedule avoids having cron launch multiple 'git for-each-repo' commands in parallel. Such parallel commands would likely lead to the 'hourly' and 'daily' tasks competing over the object database lock. This could lead to to some tasks never being run! Since the --schedule=<frequency> argument will run all tasks with _at least_ the given frequency, the daily runs will also run the hourly tasks. Similarly, the weekly runs will also run the daily and hourly tasks. The GIT_TEST_CRONTAB environment variable is not intended for users to edit, but instead as a way to mock the 'crontab [-l]' command. This variable is set in test-lib.sh to avoid a future test from accidentally running anything with the cron integration from modifying the user's schedule. We use GIT_TEST_CRONTAB='test-tool crontab <file>' in our tests to check how the schedule is modified in 'git maintenance (start|stop)' commands.

2020-07-14test-lib: set deterministic default author/committer dateJeff King
We always set the name and email for committer and author idents to make the test suite more deterministic, but not timestamps. Many scripts use test_tick to get consistent and sensibly incrementing timestamps as they create commits. But other scripts don't particularly care about the timestamp, and are happy to use whatever the current system time is. This non-determinism can be annoying: - when debugging a test, comparing results between two runs can be difficult, because the commit ids change - this can sometimes cause tests to be racy. E.g., traversal order depends on timestamp order. Even in a well-ordered set of commands, because our timestamp granularity is one second, two commits might sometimes have the same timestamp and sometimes differ. Let's set a default timestamp for all scripts to use. Any that use test_tick already will be unaffected (because their first test_tick call will overwrite our default), but it will make things a bit more deterministic for those that don't. We should be able to choose any time we want here. I picked this one because: - it differs from the initial test_tick default, which may make it easier to distinguish when debugging tests. I picked "April 1st 13:14:15" in the hope that it might stand out. - it's slightly before the test_tick default. Some tests create some commits before the first call to test_tick, so using an older timestamps for those makes sense chronologically. Note that this isn't how things currently work (where system times are usually more recent than test_tick), but that also allows us to flush out a few hidden timestamp dependencies (like the one recently fixed in t5539). - we could likewise pick any timezone we want. Choosing +0000 would have required fixing up fewer tests, but we're more likely to turn up interesting cases by not matching $TZ exactly. And since test_tick already checks "-0700", let's try something in the "+" zone range for variety. It's possible that the non-deterministic times could help flush out bugs (e.g., if something broke when the clock flipped over to 2021, our test suite would let us know). But historically that hasn't been the case; all time-dependent outcomes we've seen turned out to be accidentally flaky tests (which we fixed by using test_tick). If we do want to cover handling the current time, we should dedicate one script to doing so, and have it unset GIT_COMMITTER_DATE explicitly.

Instead; test for it using a previously added extension to test-tool and use that, together with a function that identifies when regcomp/regexec will be called with broken patterns to avoid any test that would otherwise rely on undefined behaviour. The description of the first test which wasn't accurate has been corrected, and the test rearranged for clarity, including a helper function that avoids overly long lines. Only the affected engines will have their tests suppressed, also including "fixed" if the PCRE optimization that uses LIBPCRE2 since b65abcafc7 (grep: use PCRE v2 for optimized fixed-string search, 2019-07-01) is not available.

2020-05-18tests: skip small-stack tests on hppa architectureGreg Price
On hppa these tests crash because the allocated stack space is too small, even after it was doubled in b9a190789 (and the data size doubled to match) to make it work on powerpc. For this arch just skip these tests, which is enough to make the whole suite pass.

662f9cf154 (tests: when run in Bash, annotate test failures with file name/line number, 2020-04-11), introduces a way to report the location (file:lineno) of a failed test case by traversing the bash callstack. The implementation requires bash and uses shell arrays and is therefore protected by a guard but NetBSD sh will still have to parse the function and therefore will result in: ** t0000-basic.sh *** ./test-lib.sh: 681: Syntax error: Bad substitution Enclose the bash specific code inside an eval to avoid parsing errors in the same way than 5826b7b595 (test-lib: check Bash version for '-x' without using shell arrays, 2019-01-03) Signed-off-by: Carlo Marcelo Arenas Belón <carenas@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2020-04-23t/test-lib.sh: make ULIMIT_FILE_DESCRIPTORS available to testsTaylor Blau
In t1400 the prerequisite 'ULIMIT_FILE_DESCRIPTORS' is defined and used to effectively guard the helper function 'run_with_limited_open_files' from being used on systems that do not satisfy this prerequisite. In the subsequent patch, we will introduce another test outside of t1400 that would benefit from using this prerequisite. So, move it to 'test-lib.sh' instead so that it can be used by multiple tests. Signed-off-by: Taylor Blau <me@ttaylorr.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2020-04-10tests: when run in Bash, annotate test failures with file name/line numberJohannes Schindelin
When a test fails, it is nice to see where the corresponding code lives in the worktree. Sadly, it seems that only Bash allows us to infer this information. Let's do it when we detect that we're running in a Bash. This will come in handy in the next commit, where we teach the GitHub Actions workflow to annotate failed test runs with this information.

2020-03-26tests: do not let lazy prereqs inside `test_expect_*` turn off tracingJohannes Schindelin
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.

2020-03-25test-lib: allow short options to be bundledMatheus Tavares
When debugging a test (or a set of tests), it's common to execute it with some combination of short options, such as: $ ./txxx-testname.sh -d -x -i In cases like this, CLIs usually allow the short options to be bundled in a single argument, for convenience and agility. Let's add this feature to test-lib, allowing the above command to be run as: $ ./txxx-testname.sh -dxi (or any other permutation, e.g. '-ixd') Note: Short options that require an argument can also be used in a bundle, in any position. So, for example, '-r 5 -x', '-xr 5' and '-rx 5' are all valid and equivalent. A special case would be having a bundle with more than one of such options. To keep things simple, this case is not allowed for now. This shouldn't be a major limitation, though, as the only short option that requires an argument today is '-r'. And concatenating '-r's as in '-rr 5 6' would probably not be very practical: its unbundled format would be '-r 5 -r 6', for which test-lib currently considers only the last argument. Therefore, if '-rr 5 6' were to be allowed, it would have the same effect as just typing '-r 6'. Note: the test-lib currently doesn't support '-r5', as an alternative for '-r 5', so the former is not supported in bundles as well.

2020-03-23tests(junit-xml): avoid invalid XMLJohannes Schindelin
When a test case is run in a subshell, we finalize the JUnit-style XML when said subshell exits. But then we continue to write into that XML as if nothing had happened. This leads to Azure Pipelines' Publish Test Results task complaining: Failed to read /home/vsts/work/1/s/t/out/TEST-t0000-basic.xml. Error : Unexpected end tag. Line 110, position 5. And indeed, the resulting XML is incorrect. Let's "re-open" the XML in such a case, i.e. remove the previously added closing tags.

2020-02-24t: use hash-specific lookup tables to define test constantsbrian m. carlson
In the future, we'll allow developers to run the testsuite with a hash algorithm of their choice. To make this easier, compute the fixed constants using test_oid. Move the constant initialization down below the point where test-lib-functions.sh is loaded so the functions are defined. Note that we don't provide a value for the OID_REGEX value directly because writing a large number of instances of "[0-9a-f]" in the oid-info files is unwieldy and there isn't a way to compute it based on those values. Instead, compute it based on ZERO_OID. Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
