Adjust tests so that they won't scream when the default initial
branch name is changed to 'main'.
* js/default-branch-name-part-4-minus-1:
t1400: prepare for `main` being default branch name
tests: prepare aligned mentions of the default branch name
t9902: prepare a test for the upcoming default branch name
t3200: prepare for `main` being shorter than `master`
t5703: adjust a test case for the upcoming default branch name
t6200: adjust suppression pattern to also match "main"
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.

Platform dependent tweak to a test for HP-PA.
* gp/hppa-stack-test-fix:
tests: skip small-stack tests on hppa architecture
|
|
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
(grep: use PCRE v2 for optimized fixed-string search, 2019-07-01) is not
available.

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

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:

When a test fails, it is nice to see where the corresponding code lives

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.

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.

(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

With './t1234-foo.sh -r 5,6' we can run only specific test cases in a
test script, but our test framwork still evaluates all lazy prereqs
that the excluded test cases might depend on. This is unnecessary and
produces verbose and trace output that can be distracting. This has
been an issue ever since the '-r|--run=' options were introduced in
0445e6f0a1 (test-lib: '--run' to run only specific tests, 2014-04-30),
because that commit added the check of the list of test cases
specified with '-r' after evaluating the prereqs.
Avoid this unnecessary prereq evaluation by checking the list of test
cases specified with '-r' before looking at the prereqs.
Note that GIT_SKIP_TESTS has always been checked before the prereqs,
so prereqs necessary for tests skipped that way were not evaluated.

In many projects the number of contributors is low enough that users know
each other and the full email address doesn't need to be displayed.
Displaying only the author's username saves a lot of columns on the screen.
Existing 'e/E' (as in "%ae" and "%aE") placeholders would show the
author's address as "prarit@redhat.com", which would waste columns to show
the same domain-part for all contributors when used in a project internal
to redhat. Introduce 'l/L' placeholders that strip '@' and domain part from
the e-mail address.

CI updates.
* js/azure-pipelines-msvc:
ci: also build and test with MS Visual Studio on Azure Pipelines
ci: really use shallow clones on Azure Pipelines
tests: let --immediate and --write-junit-xml play well together
test-tool run-command: learn to run (parts of) the testsuite
vcxproj: include more generated files
vcxproj: only copy `git-remote-http.exe` once it was built
msvc: work around a bug in GetEnvironmentVariable()
msvc: handle DEVELOPER=1
msvc: ignore some libraries when linking
compat/win32/path-utils.h: add #include guards
winansi: use FLEX_ARRAY to avoid compiler warning
msvc: avoid using minus operator on unsigned types
push: do not pretend to return `int` from `die_push_simple()`

When the `--immediate` option is in effect, any test failure will
immediately exit the test script. Together with `--write-junit-xml`, we
will want the JUnit-style `.xml` file to be finalized (and not leave the
XML incomplete). Let's make it so.
This comes in particularly handy when trying to debug via Azure
Pipelines, where the JUnit-style XML is consumed to present the test
results in an informative and helpful way.
While at it, also handle the `error()` code path.
The only remaining code path that sets `GIT_EXIT_OK` happens whenever
the trash directory could not be set up, i.e. long before the JUnit XML
was written, therefore we should _not_ try to finalize that XML in that
case.
It is tempting to change the `immediate` code path to just hand off to
`error`, simplifying the code in the process. That would, however,
result in a change of behavior (an additional error message) in the test
suite, which is outside of the purview of the current patch series: its
goal is to allow building Git with Visual Studio and testing it with a
portable version of Git for Windows.

In many test scripts, there are bespoke definitions of the single quote
that are some variation of this:
SQ="'"
Define a common $SQ variable in test-lib.sh and replace all usages of
these bespoke variables with the common one.
This change was done by running `git grep =\"\'\" t/` and
`git grep =\\\\\'` and manually changing the resulting definitions and
corresponding usages.

The first line of verbose output from each test piece now carries
the test name and number to help scanning with eyeballs.
* sg/show-failed-test-names:
tests: show the test name and number at the start of verbose output
t0000-basic: use realistic test script names in the verbose tests

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.
So the dummy test above would start like this:
expecting success of 9999.1 'commit works':
echo content >file &&

Many GIT_TEST_* environment variables control various aspects of
how our tests are run, but a few followed "non-empty is true, empty
or unset is false" while others followed the usual "there are a few
ways to spell true, like yes, on, etc., and also ways to spell
false, like no, off, etc." convention.
* ab/test-env:
env--helper: mark a file-local symbol as static
tests: make GIT_TEST_FAIL_PREREQS a boolean
tests: replace test_tristate with "git env--helper"
tests README: re-flow a previously changed paragraph
tests: make GIT_TEST_GETTEXT_POISON a boolean
t6040 test: stop using global "script" variable
config.c: refactor die_bad_number() to not call gettext() early
env--helper: new undocumented builtin wrapping git_env_*()

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.
