There's no point in creating a repository or directory only to decide
right afterwards that we're skipping all the tests. We can save
ourselves the redundant "git init" or "mkdir" and "rm -rf" in this
case.
We carry around the "$remove_trash" variable because if the directory
is unexpectedly gone at test_done time we'll still want to hit the
"trash directory already removed" error, but not if we never created
the trash directory. See df4c0d1a792 (test-lib: abort when can't
remove trash directory, 2017-04-20) for the addition of that error.
So let's partially revert 06478dab4c (test-lib: retire $remove_trash
variable, 2017-04-23) and move the decision about whether to skip all
tests earlier.
Let's also fix a bug that was with us since abc5d372ec (Enable
parallel tests, 2008-08-08): we would leak $remove_trash from the
environment. We don't want this to error out, so let's reset it to the
empty string first:
remove_trash=t GIT_SKIP_TESTS=t0001 ./t0001-init.sh
I tested this with --debug, see 4d0912a206 (test-lib.sh: do not barf
under --debug at the end of the test, 2017-04-24) for a bug we don't
want to re-introduce.
While I'm at it, let's move the HOME assignment to just before
test_create_repo, it could be lower, but it seems better to set it
before calling anything in test-lib-functions.sh

Remove the last uses of the C_LOCALE_OUTPUT prerequisite as well as
the prerequisite itself. This is a follow-up to d162b25f956 (tests:
remove support for GIT_TEST_GETTEXT_POISON, 2021-01-20), as well as
the preceding commit where we removed the simpler uses of
C_LOCALE_OUTPUT.
Here I'm slightly refactoring a test added in 21e5ad50fc5 (safecrlf:
Add mechanism to warn about irreversible crlf conversions,
2008-02-06), as well as getting rid of another "test_have_prereq
C_LOCALE_OUTPUT" use.
I'm not leaving the prerequisite itself in place for in-flight changes
as there currently are none that introduce new tests that rely on it,
and because C_LOCALE_OUTPUT is currently a noop on the master branch
we likely won't have any new submissions that use it.

'./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'.

Remove support for using version 1 of the PCRE library. Its use has
been discouraged by upstream for a long time, and it's in a
bugfix-only state.
Anyone who was relying on v1 in particular got a nudge to move to v2
in e6c531b808 (Makefile: make USE_LIBPCRE=YesPlease mean v2, not v1,
2018-03-11), which was first released as part of v2.18.0.
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). I don't see the point, and
it makes the history/blame harder to read. Maybe if there's ever a
PCRE v3...

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).

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.

Adjust tests so that they won't scream when the default initial

tests: start moving to a different default main branch name
t9801: use `--` in preparation for default branch rename
fmt-merge-msg: also suppress "into main" by default
|
|
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`.

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.

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.

Currently, the SHA1 prerequisite depends on the output of git
hash-object. However, in order for that to produce sane behavior, we
must be in a repository. If we are not, the default will remain SHA-1,
and we'll produce wrong results if we're using SHA-256 for the testsuite
but the test assertion starts when we're not in a repository.
Check the environment variable we use for this purpose, leaving it to
default to SHA-1 if none is specified.

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.

|
7187c7bbb8 (t4210: skip i18n tests that don't work on FreeBSD, 2019-11-27)
adds a REG_ILLSEQ prerequisite, and to do that copies the common branch in
test-lib and expands it to include it in a special case for FreeBSD.
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

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)

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.

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.

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.

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.

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.

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.

Testfix.
* js/test-write-junit-xml-fix:
tests: fix --write-junit-xml with subshells
|
|
In t0000, more precisely in its `test_bool_env` test case, there are two
subshells that are supposed to fail. To be even _more_ precise, they
fail by calling the `error` function, and that is okay, because it is in
a subshell, and it is expected that those two subshell invocations fail.
However, the `error` function also tries to finalize the JUnit XML (if
that XML was asked for, via `--write-junit-xml`. As a consequence, the
XML is edited to add a `time` attribute for the `testsuite` tag. And
since there are two expected `error` calls in addition to the final
`test_done`, the `finalize_junit_xml` function is called three times and
naturally the `time` attribute is added _three times_.
Azure Pipelines is not happy with that, complaining thusly:
##[warning]Failed to read D:\a\1\s\t\out\TEST-t0000-basic.xml. Error : 'time' is a duplicate attribute name. Line 2, position 82..
One possible way to address this would be to unset `write_junit_xml` in
the `test_bool_env` test case.
But that would be fragile, as other `error` calls in subshells could be
introduced.
So let's just modify `finalize_junit_xml` to remove any `time` attribute
before adding the authoritative one.
