For various reasons (see discussion at [1]) we would like an alternative
to `prove` for running test suites (including the unit tests) on
Windows.
This series extends the existing `test-tool run-command testsuite` to
support running unit tests. In addition, it includes some small
cleanups: we move t-basic out of the unit-tests directory, and add a
test wrapper script to allow unit tests and the shell test suite to run
in a single `prove` process.
Some known remaining bits of work:
* We need to filter out cmake *.pdb files when running with `test-tool`.
* We should investigate switching the Windows CI to use `test-tool`
instead of prove.
* We should determine whether it is confusing or otherwise harmful to
people's workflow to have the unit tests run in parallel with shell
tests when using prove as the default test target.

While t/unit-tests/t-basic.c uses the unit-test framework added in
e137fe3b29 (unit tests: add TAP unit test framework, 2023-11-09), it is
not a true unit test in that it intentionally fails in order to exercise
various codepaths in the unit-test framework. Thus, we intentionally
exclude it when running unit tests through the various t/Makefile
targets. Instead, it is executed by t0080-unit-test-output.sh, which
verifies its output follows the TAP format expected for the various
pass, skip, or fail cases.
As such, it makes more sense for t-basic to be a helper item for
t0080-unit-test-output.sh, so let's move it to t/t0080/t-basic.c and
adjust Makefiles and .gitignores as necessary.
This has the additional benefit that test harnesses seeking to run all
unit tests can find them with a simple glob of "t/unit-tests/bin/t-*",
with no exceptions needed. This will be important in a later patch where
we add support for running the unit tests via a test-tool subcommand.

Teach the testsuite runner in `test-tool run-command testsuite` how to
run unit tests, by adding two new flags:
First, "--(no-)run-in-shell" allows the test-tool to exec the unit-test
binaries directly, rather than trying to interpret them as shell
scripts.
Second "--(no-)require-shell-test-pattern" bypasses the check that the
test filenames match the expected t####-*.sh pattern.
With these changes, you can now use test-tool to run the unit tests:
$ make
$ cd t/unit-tests/bin
$ ../../helper/test-tool run-command testsuite --no-run-in-shell \
--no-require-shell-test-pattern
This should be helpful on Windows to allow running tests without
requiring Perl (for `prove`), as discussed in [1] and [2].

In the previous commit, we added support in test-tool for running
collections of unit tests. Now, add rules in t/Makefile for running in
this way.
This new rule can be executed from the top-level Makefile via
`make DEFAULT_UNIT_TEST_TARGET=unit-tests-test-tool unit-tests`, or by
setting DEFAULT_UNIT_TEST_TARGET in config.mak.
NEEDS WORK: we need to exclude .pdb files generated by cmake [see
0df903d402 (unit-tests: do not mistake `.pdb` files for being
executable, 2023-09-25)]

Add a wrapper script to allow `prove` to run both shell tests and unit
tests from a single invocation. This avoids issues around running prove
twice in CI, as discussed in [1].
Additionally, this moves the unit tests into the main dev workflow, so
that errors can be spotted more quickly.
NEEDS WORK: as discussed in previous commits in this series, there's a
desire to avoid `prove` specifically and (IIUC) unnecessary
fork()/exec()ing in general on Windows. This change adds an extra exec()
for each shell and unit test execution, will that be a problem for
Windows?

... this conclusion. I somehow thought that t-basic part would be a
good test-tool subcommand, as it is run from the suite of shell
scripts for end-to-end testing CLI interaction.
Do we have any precedent to place programs placed under t/tXXXX/ and
get them compiled?

And this motivation is very much understandable, and for that, as
long as it is outside t/unit-tests/, it would be good. I just did
not expect it to hang under t/t0080/, inviting more unit test pieces
that are triggerable from the numberd shell scripts to hang under
random t/t[0-9][0-9][0-9][0-9]/ directories.

This one I am not so sure. Do we still have situations where
erroring out when fed a non t[0-9][0-9][0-9][0-9]-*.sh script is
problematic? IOW, do we need to keep it as conditional?
... goes and looks ...
Ah, this variable/option is misnamed and that is what invited the
above nonsense question out of me. The logic this option disables
does not "require" (and error out if the requirement is not met); it
is used in a loop over "ls *" and "filtering" files out that are not
the numbered scripts.
But that confusion makes me wonder if non-script side of tests would
also want some filtering in the longer run, even if the directory we
feed to "test-tool run" happens to contain nothing but what we want
to run right now. I wonder if we instead want a variable that holds
a pattern used to match programs readdir() discovers and skip those
that do not match the pattern? Its default value may be something
like "t[0-9][0-9][0-9][0-9]-*.sh" but alternatively you can give,
say, "*" to pass everything, or something like that.

This makes me wonder why we want to do the readdir() loop ourselves.
Instead of saying --no-require-shell-test-pattern there, wouldn't it
be simpler to say "*" right there, and have testsuite() run the test
programs named from the command line?
But that is orthogonal to the enhancement we have here.

It is probably confusing especially given that the testsuite() thing
does its own parallel spawning of tests while prove does its own.
Is there a reason to choose unit-tests-test-tool Makefile target on
prove-capable platforms (other than for testing the test-tool)?
Thanks for an entertaining read.

This may be a stupid question, but do we even need the current "push
'sh' to the strvec"? If our executable shell scripts run just fine
without, then this may not have to be conditional.

Heh, I was about to ask the same thing.
In particular...
> Do we have any precedent to place programs placed under t/tXXXX/ and

...no, I don't think we do. And quite often I exclude those directories
when grepping around the code base, because there is often code there
that is purely used as a data fixture. E.g., t4256 contains a copy of
mailinfo.c which it uses as input for some of the tests. That code also
happens to have out-of-bounds memory reads which we have since fixed in
the real mailinfo.c, but of course "grep" finds them both. :)
So I would prefer a rule like "no buildable code in t/t[0-9]*". Barring
that, maybe we could avoid using things that look too much like real Git
code in our tests (though we sometimes do need fake code for things like
funclines, and even that might end up creating false positives).

It is necessary for the same reason that the indirection provided by
patch 4 is necessary: the test scripts are supposed to be run by
TEST_SHELL_PATH, even if they may say "#!/bin/sh" in their header.
But the "testsuite" helper just hard-codes "sh", which is wrong. It's
somewhat academic for Windows where "sh" is already bash, and that's the
only reasonable thing anybody would set TEST_SHELL_PATH to anyway. But
if the point is to be a drop-in replacement for the existing flow, it
should be checking getenv("TEST_SHELL_PATH"). And perhaps the Makefile
might need to correctly export the variable.

Ack. I've moved this to a test-tool subcommand for V2, which I hope to
send out soon.

It's speculation on my part, but I wonder if it has something to do with
the number of shell tests? Google tells me that on Windows, the maximum
command line length is 8191 characters. Which is actually a fair bit
smaller than expanding the shell test list:
$ echo t????-*.sh | wc -c

The original implementation and this series both still allow passing
additional patterns on the command line. Only tests matching the
hardcoded t[0-9][0-9][0-9][0-9]-*.sh pattern plus all the command-line
patterns will be run. The new flag just bypasses the hardcoded pattern.
Given that V2 will already be changing in non-backwards-compatible ways,
I think it makes the most sense to just delete the hardcoded pattern and
require callers to provide it if they want it.

Actually, I misspoke here. The test must match the hardcoded pattern
plus at least one of the command-line patterns (if any were provided).

Given that it sounds like the testsuite functionality is not really used
at the moment, I still feel OK with changing the pattern matching logic
here for V2.

Please note: this series has been rebased onto jk/unit-tests-buildfix.
For various reasons (see discussion at [1]) we would like an alternative
to `prove` for running test suites (including the unit tests) on
Windows.
This series extends the existing `test-tool run-command testsuite` to
support running unit tests. In addition, it includes some small
cleanups:
* move t-basic out of the unit-tests directory
* don't hardcode the shell for running tests in `test-tool ... testsuite`
* don't hardcode a test name filter in `test-tool ... testsuite`
* add a test wrapper script to allow unit tests and the shell test suite
to run in a single `prove` process
Some known remaining bits of work:
* We should investigate switching the Windows CI to use `test-tool`
instead of prove. However, Windows CI seems broken on
jk/unit-tests-buildfix, and I haven't had time to determine why.
* We should determine whether it is confusing or otherwise harmful to
people's workflow to have the unit tests run in parallel with shell
tests when using prove as the default test target.
[1] https://lore.kernel.org/git/pull.1613.git.1699894837844.gitgitgadget@gmail.com/
Changes in V2:
* Patch 1: move t-basic to a test-tool subcommand rather than a new
executable under t/t0080/
* New patch 2: get the shell path from TEST_SHELL_PATH in
`test-tool run-command testsuite`
* New patch 3: remove the hardcoded filename filter in
`test-tool run-command testsuite`
* Patch 4 (previously 2): simplified now that we no longer need to add
any command-line flags to support unit tests

test-tool run-command testsuite: support unit tests
Teach the testsuite runner in `test-tool run-command testsuite` how to
- run unit tests, by adding two new flags:
+ run unit tests: if TEST_SHELL_PATH is not set, assume that we're running
+ the programs directly from CWD, rather than defaulting to "sh" as an
+ interpreter.
- First, "--(no-)run-in-shell" allows the test-tool to exec the unit-test
- binaries directly, rather than trying to interpret them as shell
- scripts.
-
- Second "--(no-)require-shell-test-pattern" bypasses the check that the
- test filenames match the expected t####-*.sh pattern.
-
- With these changes, you can now use test-tool to run the unit tests:
+ With this change, you can now use test-tool to run the unit tests:
$ make
$ cd t/unit-tests/bin
- $ ../../helper/test-tool run-command testsuite --no-run-in-shell \
- --no-require-shell-test-pattern

This should be helpful on Windows to allow running tests without
requiring Perl (for `prove`), as discussed in [1] and [2].
+ This again breaks backwards compatibility, as it is now required to set
+ TEST_SHELL_PATH properly for executing shell scripts, but again, as

While t/unit-tests/t-basic.c uses the unit-test framework added in
e137fe3b29 (unit tests: add TAP unit test framework, 2023-11-09), it is
not a true unit test in that it intentionally fails in order to exercise
various codepaths in the unit-test framework. Thus, we intentionally
exclude it when running unit tests through the various t/Makefile
targets. Instead, it is executed by t0080-unit-test-output.sh, which
verifies its output follows the TAP format expected for the various
pass, skip, or fail cases.
As such, it makes more sense for t-basic to be a helper item for
t0080-unit-test-output.sh, so let's move it to
t/helper/test-example-tap.c and adjust Makefiles as necessary.
This has the additional benefit that test harnesses seeking to run all
unit tests can find them with a simple glob of "t/unit-tests/bin/t-*",
with no exceptions needed. This will be important in a later patch where
we add support for running the unit tests via a test-tool subcommand.

When running tests through `test-tool run-command testsuite`, we
currently hardcode `sh` as the command interpreter. As discussed in [1],
this is incorrect, and we should be using the shell set in
TEST_SHELL_PATH instead.
Add a shell_path field in struct testsuite so that we can pass this to
the task runner callback. If this is non-null, we'll use it as the
argv[0] of the subprocess. Otherwise, we'll just execute the test
program directly.
When setting up the struct testsuite in testsuite(), use the value
of TEST_SHELL_PATH if it's set, otherwise default to `sh`.

`test-tool run-command testsuite` currently assumes that it will only be
running the shell test suite, and therefore filters out anything that
does not match a hardcoded pattern of "t[0-9][0-9][0-9][0-9]-*.sh".
Later in this series, we'll adapt `test-tool run-command testsuite` to
also support unit tests, which do not follow the same naming conventions
as the shell tests, so this hardcoded pattern is inconvenient.
Since `testsuite` also allows specifying patterns on the command-line,
let's just remove this pattern. As noted in [1], there are no longer any
uses of `testsuite` in our codebase, it should be OK to break backwards
compatibility in this case. We also add a new filter to avoid trying to

directory can do so without specifying a pattern.

Teach the testsuite runner in `test-tool run-command testsuite` how to
run unit tests: if TEST_SHELL_PATH is not set, assume that we're running
the programs directly from CWD, rather than defaulting to "sh" as an
interpreter.
With this change, you can now use test-tool to run the unit tests:
$ make
$ cd t/unit-tests/bin
$ ../../helper/test-tool run-command testsuite
This should be helpful on Windows to allow running tests without
requiring Perl (for `prove`), as discussed in [1] and [2].
This again breaks backwards compatibility, as it is now required to set
TEST_SHELL_PATH properly for executing shell scripts, but again, as
noted in [2], there are no longer any such invocations in our codebase.

In the previous commit, we added support in test-tool for running
collections of unit tests. Now, add rules in t/Makefile for running in
this way.
This new rule can be executed from the top-level Makefile via
`make DEFAULT_UNIT_TEST_TARGET=unit-tests-test-tool unit-tests`, or by
setting DEFAULT_UNIT_TEST_TARGET in config.mak.

Add a wrapper script to allow `prove` to run both shell tests and unit
tests from a single invocation. This avoids issues around running prove
twice in CI, as discussed in [1].
Additionally, this moves the unit tests into the main dev workflow, so
that errors can be spotted more quickly.
NEEDS WORK: as discussed in previous commits in this series, there's a
desire to avoid `prove` specifically and (IIUC) unnecessary
fork()/exec()ing in general on Windows. This change adds an extra exec()
for each shell and unit test execution, will that be a problem for
Windows?

Thanks to Dscho who figured this out, the jk/unit-tests-buildfix
topic in my tree has been updated to pass "win test (n)" jobs.

I do not know much about "confusing" thing, but if the user
allocates, say, 16 jobs to run tests in parallel, and one of them
drives the "unit test suite runner" that wants to do its own
parallelism, we'd easily end up busting the resource limit the
end-user desires. It does not necessarily mean that we should limit
the parallelism of "unit test suite runner" to 1 under prove, though.

Judging from the last patch in this series it seems likely that we'll
want to run unit tests and integration tests parallel. In which case it
might be better to look at the filename extension to decide whether to
sh as an interpreter so that we can avoid having to use a wrapper
script. Then
cd t
helper/test-tool run-command testsuite 't[0-9]*.sh' 'unit-tests/bin/*'
would run the integration tests via "sh" and the unit-tests directly.
We'd need to figure out how to look for tests in both directories as
well though...
Best Wishes

Hmph. It sounds more like "the run-command testsuite subcommand
only runs programs in the current directory", not "assume" (which
implies there is a way to override the assumption). Not that the
limitation would hurt us in any way, though.

It sounds more like "If TEST_SHELL_PATH is not given, then we run
them in the current directory.".
It is perfectly fine, because ...

... this "prefixing" is done to a path discovered by readdir() from
a directory handle obtained by opendir("."). If there were a way to
pass paths to executables directly, possibly as absolute paths, the
unconditional prefixing of "./" would have been a problem, but we do
not have such a facility, so this should be OK.

This limits us to the tests that the Makefile knows about, which is
good. Of course, we might bust the command line length limit some
day when we have too many unit test executables, but for now this is
simple, clean, and readable.

Hmph. This penalizes the non-unit tests by doing an extra "exec",
once per program?
Of course we cannot run two $(PROVE) invocations serially, one for
doing $(T) and the other for doing $(UNIT_TESTS)?

As the first thing both of these headers include is
"git-compat-util.h", so the ordering should be safe either way,
because everybody else in the directory seems to include
"test-tool.h" before including headers that are specific to the
subsystem it is testing, and "t/unit-tests/test-lib.h" in this case
is the header that is specific to the unit-test subsystem being
tested, it may raise fewer eyebrows if we swapped the order of the
inclusion here.
Other than that, looks good to me.
Thanks.

That sounds nice in theory, but ...

... this done in the testsuite() function, doesn't suite.shell_path
always gets some non-NULL value? Perhaps in a later step we will
add a mechanism to allow suite.shell_path to be NULL when we know
we are running an executable, or something?
Leaving readers in a bit of suspense may, especially in a series
that is short like this, be a good technique to entice them to keep
reading, perhaps, but anyway, if that is what is intended, a simple
"this feature is not used in this step, but we will take advantage
of it soon in a later step" would be a good idea.

As we discussed in Peff's Makefile change that enumerates "which are
the unit-test programs?" Generally, $(wildcard) and readdir() to
slurp everything in a directory, including stuff that is an
untracked cruft, is not an excellent idea.
This is not an end-user facing program and we are in full control of
its input (most notably, "which ones should we be running?"), I do
not think it would be a huge issue, though.

The first one seems to have been resolved. The latter can happen

It does, but IMHO that is not likely to be a problem. It's once per
top-level script (so ~1000), and each of those scripts spawns hundreds
or thousands of sub-commands. I didn't do any measurements, though.
You can extend "prove" with extra perl modules so that it makes the
distinction internally without the extra shell invocation. But when I
tried to do it, I found it rather baroque and complicated (I can't
remember if I succeeded but found it too gross, or just gave up halfway
through trying).
> Of course we cannot run two $(PROVE) invocations serially, one for

Not if they share the same command-line options. If you use something
like "--state=slow,save", then the first run will write the list of all
tests to ".prove", and then the second will run every test mentioned in
.prove (in addition to the unit-tests provided on the command-line).
You should be able to work around it by passing "--statefile". I _think_
it might be OK to just do that unconditionally. Something like:
prove --exec $(TEST_SHELL_PATH $(GIT_PROVE_OPTS) $(T) :: $(GIT_TEST_OPTS)
prove --statefile=.prove-unit-tests $(GIT_PROVE_OPTS) $(UNIT_TESTS) :: $(GIT_TEST_OPTS)
and then it's just a noop if GIT_PROVE_OPTS doesn't use --state. But I
haven't played with it myself.

Is this last paragraph still accurate? I think in this rebased version
of the series, we'll continue to use $(UNIT_TESTS) derived from the
source list rather than a glob in bin/.

This drops the intermediate UNIT_TEST_PROGRAMS, which makes sense. It
was only used to keep the long lines a bit more readable. But it also
drops the $(sort) call. Do we need to keep it?
Certainly I'd think we want the contents of $(UNIT_TESTS) to be in a
deterministic order. Does the $(wildcard) function already return things
in sorted order? I can't find any mention in the documention. It seems
to do so for me in a simple test, but aae5239be2 (t/Makefile: Use $(sort
...) explicitly where needed, 2011-09-04) argues otherwise.
So I think we probably want to keep it (or possibly move it onto the
UNIT_TEST_SOURCES line, which keeps it close to the wildcard call).

I do not think it warrants such complexity. The wrapper script is
fine.

I see this line in the docs [1]: "As with wildcard expansion in rules,
the results of the wildcard function are sorted". GNU Make has restored
the sorted behavior of $(wildcard) since 2018 [2]. I'll leave the sort
off for now, but if folks feel like we need to support older versions of
`make`, I'll add it back.

At the moment, I'm not planning on trying to make unit tests and shell
tests run under the same test-tool process. If that is a valuable
change, hopefully the Windows / CI experts can use this series as a
starting point to make additional test-tool changes. However, I will
probably not spend any further time on this area.

Thanks for digging. I thought I was certain that woldcard is sorted
and stable and was quite perplexed when I could not find the mention
in a version of doc I had handy ("""This is Edition 0.75, last
updated 19 January 2020, of 'The GNU Make Manual', for GNU 'make'
version 4.3.""").

Would you prefer if I remove the default behavior of "run everything in
the CWD" and require passing in at least one filename filter?

The current `prove` helper script does not do any separate parallelism,
so we are fine in that case, and the new test-tool runner does not
currently support running both unit tests and shell tests in the same
process, so we should be OK in either case.

No preference either way at all.

Likewise (mine is the latest version in Debian unstable). The change to
sort comes from their[1] eedea52a, which was in GNU make 4.2.90. But the
matching documentation change didn't happen until 5b993ae, which was
4.3.90 in late 2021. So that explains the mystery.
Those dates imply to me that we should keep the $(sort), though. Six
years is not so long in distro timescales, especially given that Debian
unstable is on a 4-year-old version. (And if we did want to get rid of
it, certainly we should do so consistently across the Makefile in a
separate patch).

I am stuck on 4.2.1 and cannot get to 4.3.90 any time soon. Can you want on this? It will take us out unless we can suppress the $(sort)

Sounds sensible. The topic is expecting a reroll so I'll make sure
I won't touch it until I see an update.

Makes sense, thanks for investigating. I've restored the $(sort) in V3.

Hi Randall,
I'm not sure I follow here. The change in 4.2.90 is that wildcard
expansion becomes sorted by default again. So adding the $(sort) back
shouldn't cause any problems in 4.2.1. Or did I misunderstand your
point?

I thought you were referring to a new ${sort} behaviour in 4.2.90. My bad.

Please note: this series has once again been rebased onto the latest
jk/unit-tests-buildfix.
For various reasons (see discussion at [1]) we would like an alternative
to `prove` for running test suites (including the unit tests) on
Windows.
[1] https://lore.kernel.org/git/pull.1613.git.1699894837844.gitgitgadget@gmail.com/
This series extends the existing `test-tool run-command testsuite` to
support running unit tests. In addition, it includes some small
cleanups:
* move t-basic out of the unit-tests directory
* don't hardcode the shell for running tests in `test-tool ... testsuite`
* don't hardcode a test name filter in `test-tool ... testsuite`
* add a test wrapper script to allow unit tests and the shell test suite
to run in a single `prove` process
Changes in V3:
* Added new patch (#7) to use the new test-tool runner for unit tests in
Windows CI.
* Restored the explicit sort call in t/Makefile, for backwards
compatibility with older GNU Make versions.
* Rebased the series on the latest jk/unit-tests-buildfix branch.
* Fixed header include order in patch #1.
* Removed a paragraph in patch #1's commit message that is obsolete now
that we're building the list of test files from the sources rather
than by globbing.
* Added a note in patch #2 that setting a NULL suite.shell_path will be
used in a later commit.
* Clarified up some sloppy wording in commit messages and comments in
t/helper/test-run-command.c.
Changes in V2:
* Rebased the series on the latest jk/unit-tests-buildfix branch.
* Patch 1: move t-basic to a test-tool subcommand rather than a new
executable under t/t0080/
* New patch 2: get the shell path from TEST_SHELL_PATH in
`test-tool run-command testsuite`
* New patch 3: remove the hardcoded filename filter in
`test-tool run-command testsuite`
* Patch 4 (previously 2): simplified now that we no longer need to add
any command-line flags to support unit tests
* Patch 5 (previously 3): avoid trying to run cmake *.pdb files by using
the unit test list built in the makefile in jk/unit-tests-buildfix.

@@ Commit message
t0080-unit-test-output.sh, so let's move it to
t/helper/test-example-tap.c and adjust Makefiles as necessary.
- This has the additional benefit that test harnesses seeking to run all
- unit tests can find them with a simple glob of "t/unit-tests/bin/t-*",
- with no exceptions needed. This will be important in a later patch where
- we add support for running the unit tests via a test-tool subcommand.

While t/unit-tests/t-basic.c uses the unit-test framework added in
e137fe3b29 (unit tests: add TAP unit test framework, 2023-11-09), it is
not a true unit test in that it intentionally fails in order to exercise
various codepaths in the unit-test framework. Thus, we intentionally
exclude it when running unit tests through the various t/Makefile
targets. Instead, it is executed by t0080-unit-test-output.sh, which
verifies its output follows the TAP format expected for the various
pass, skip, or fail cases.
As such, it makes more sense for t-basic to be a helper item for
t0080-unit-test-output.sh, so let's move it to
t/helper/test-example-tap.c and adjust Makefiles as necessary.

When running tests through `test-tool run-command testsuite`, we
currently hardcode `sh` as the command interpreter. As discussed in [1],
this is incorrect, and we should be using the shell set in
TEST_SHELL_PATH instead.
Add a shell_path field in struct testsuite so that we can pass this to
the task runner callback. If this is non-null, we'll use it as the
argv[0] of the subprocess. Otherwise, we'll just execute the test
program directly. We will use this feature in a later commit to enable
running binary executable unit tests.
However, for now when setting up the struct testsuite in testsuite(),
use the value of TEST_SHELL_PATH if it's set, otherwise keep the
original behavior by defaulting to `sh`.

`test-tool run-command testsuite` currently assumes that it will only be
running the shell test suite, and therefore filters out anything that
does not match a hardcoded pattern of "t[0-9][0-9][0-9][0-9]-*.sh".
Later in this series, we'll adapt `test-tool run-command testsuite` to
also support unit tests, which do not follow the same naming conventions
as the shell tests, so this hardcoded pattern is inconvenient.
Since `testsuite` also allows specifying patterns on the command-line,
let's just remove this pattern. As noted in [1], there are no longer any
uses of `testsuite` in our codebase, it should be OK to break backwards
compatibility in this case. We also add a new filter to avoid trying to
execute "." and "..", so that users who wish to execute every test in a
directory can do so without specifying a pattern.

Teach the testsuite runner in `test-tool run-command testsuite` how to
run unit tests: if TEST_SHELL_PATH is not set, run the programs directly
from CWD, rather than defaulting to "sh" as an interpreter.
With this change, you can now use test-tool to run the unit tests:

This should be helpful on Windows to allow running tests without
requiring Perl (for `prove`), as discussed in [1] and [2].
This again breaks backwards compatibility, as it is now required to set
TEST_SHELL_PATH properly for executing shell scripts, but again, as
noted in [2], there are no longer any such invocations in our codebase.

In the previous commit, we added support in test-tool for running
collections of unit tests. Now, add rules in t/Makefile for running in
this way.
This new rule can be executed from the top-level Makefile via
`make DEFAULT_UNIT_TEST_TARGET=unit-tests-test-tool unit-tests`, or by
setting DEFAULT_UNIT_TEST_TARGET in config.mak.

Add a wrapper script to allow `prove` to run both shell tests and unit
tests from a single invocation. This avoids issues around running prove
twice in CI, as discussed in [1].
Additionally, this moves the unit tests into the main dev workflow, so
that errors can be spotted more quickly. Accordingly, we remove the
separate unit tests step for Linux CI. (We leave the Windows CI
unit-test step as-is, because the sharding scheme there involves
selecting specific test files rather than running `make test`.)

Although the previous commit changed t/Makefile to run unit tests
alongside shell tests, the Windows CI still needs a separate unit-tests
step due to how the test sharding works.
We want to avoid using `prove` as a test running on Windows due to
performance issues [1], so use the new test-tool runner instead.

Folks, what's the status of this one? I just checked the RFC thread
and this last one (more than a month ago) and the issues seems to
have been addressed, but I prefer positive acks rather than "we've
seen it already, take our silence as the sign of endorsement".
Thanks.

An earlier step required that runs via "test-tool run-command" have
TEST_SHELL_PATH set correctly. So defaulting to /bin/sh here is
pointless, I'd think? This is used only for the in-Makefile "prove"
invocation, so running individual tests or even a manual "prove" outside
of the Makefile (where the user might not have set TEST_SHELL_PATH)
would not apply.
It obviously is not hurting anything, but I wonder if you'd want to have
it complain loudly to catch any instance where your assumption is not
true.

It is not a topic I am really interested in, so I was not following
closely. But I think my earlier issues were addressed, and from a quick
read now it looks OK to me. (I left one small comment, but I don't think
it's a big deal either way).

Actually, I think the "manual prove outside of the Makefile" situation
is worth keeping this. I know I sometimes copy commands from Makefiles
and run them manually when debugging issues, so it could be annoying for
folks if we remove the default here.

Hmm, by "manually running prove" I meant running:
prove t0001-init.sh
and so on. Or even "prove --state=failed" to re-run failed tests. But
neither of those would even use this script, because there's no --exec
option.
But it sounds like you mean literally cutting and pasting the "prove
--exec" line from the Makefile. That seems to me like a weird thing to
want to do, but OK, I'll try not to judge your workflow. ;)
But if you are worried about making debugging more confusing, it seems
like silently defaulting to /bin/sh might make things worse. It is not
necessarily what "make test" did, and complaining loudly might be more
helpful than trying to run with an alternate shell.
I don't feel too strongly about it, though. I'd generally just run
single tests as "./t0001-init.sh", which runs into the same issue. I've
been working on Git long enough that I know it is one of the possible
gotchas when a test failure does not reproduce. :)

Alright, fixed in V4. We now set TEST_SHELL_PATH when running `prove`,
and we error out in run-test.sh if TEST_SHELL_PATH is not set.

For various reasons (see discussion at [1]) we would like an alternative
to `prove` for running test suites (including the unit tests) on
Windows.
[1] https://lore.kernel.org/git/pull.1613.git.1699894837844.gitgitgadget@gmail.com/
This series extends the existing `test-tool run-command testsuite` to
support running unit tests. In addition, it includes some small
cleanups:
* move t-basic out of the unit-tests directory
* don't hardcode the shell for running tests in `test-tool ... testsuite`
* don't hardcode a test name filter in `test-tool ... testsuite`
* add a test wrapper script to allow unit tests and the shell test suite
to run in a single `prove` process
Changes in V4:
* Set TEST_SHELL_PATH when running the `prove` test target, and error
out of run-test.sh if TEST_SHELL_PATH is not set.
Changes in V3:
* Added new patch (#7) to use the new test-tool runner for unit tests in
Windows CI.
* Restored the explicit sort call in t/Makefile, for backwards
compatibility with older GNU Make versions.
* Rebased the series on the latest jk/unit-tests-buildfix branch.
* Fixed header include order in patch #1.
* Removed a paragraph in patch #1's commit message that is obsolete now
that we're building the list of test files from the sources rather
than by globbing.
* Added a note in patch #2 that setting a NULL suite.shell_path will be
used in a later commit.
* Clarified up some sloppy wording in commit messages and comments in
t/helper/test-run-command.c.
Changes in V2:
* Rebased the series on the latest jk/unit-tests-buildfix branch.
* Patch 1: move t-basic to a test-tool subcommand rather than a new
executable under t/t0080/
* New patch 2: get the shell path from TEST_SHELL_PATH in
`test-tool run-command testsuite`
* New patch 3: remove the hardcoded filename filter in
`test-tool run-command testsuite`
* Patch 4 (previously 2): simplified now that we no longer need to add
any command-line flags to support unit tests
* Patch 5 (previously 3): avoid trying to run cmake *.pdb files by using
the unit test list built in the makefile in jk/unit-tests-buildfix.

While t/unit-tests/t-basic.c uses the unit-test framework added in
e137fe3b29 (unit tests: add TAP unit test framework, 2023-11-09), it is
not a true unit test in that it intentionally fails in order to exercise
various codepaths in the unit-test framework. Thus, we intentionally
exclude it when running unit tests through the various t/Makefile
targets. Instead, it is executed by t0080-unit-test-output.sh, which
verifies its output follows the TAP format expected for the various
pass, skip, or fail cases.
As such, it makes more sense for t-basic to be a helper item for
t0080-unit-test-output.sh, so let's move it to
t/helper/test-example-tap.c and adjust Makefiles as necessary.

When running tests through `test-tool run-command testsuite`, we
currently hardcode `sh` as the command interpreter. As discussed in [1],
this is incorrect, and we should be using the shell set in
TEST_SHELL_PATH instead.
Add a shell_path field in struct testsuite so that we can pass this to
the task runner callback. If this is non-null, we'll use it as the
argv[0] of the subprocess. Otherwise, we'll just execute the test
program directly. We will use this feature in a later commit to enable
running binary executable unit tests.
However, for now when setting up the struct testsuite in testsuite(),
use the value of TEST_SHELL_PATH if it's set, otherwise keep the
original behavior by defaulting to `sh`.

`test-tool run-command testsuite` currently assumes that it will only be
running the shell test suite, and therefore filters out anything that
does not match a hardcoded pattern of "t[0-9][0-9][0-9][0-9]-*.sh".
Later in this series, we'll adapt `test-tool run-command testsuite` to
also support unit tests, which do not follow the same naming conventions
as the shell tests, so this hardcoded pattern is inconvenient.
Since `testsuite` also allows specifying patterns on the command-line,
let's just remove this pattern. As noted in [1], there are no longer any
uses of `testsuite` in our codebase, it should be OK to break backwards
compatibility in this case. We also add a new filter to avoid trying to
execute "." and "..", so that users who wish to execute every test in a
directory can do so without specifying a pattern.

Teach the testsuite runner in `test-tool run-command testsuite` how to
run unit tests: if TEST_SHELL_PATH is not set, run the programs directly
from CWD, rather than defaulting to "sh" as an interpreter.
With this change, you can now use test-tool to run the unit tests:
$ make
$ cd t/unit-tests/bin
$ ../../helper/test-tool run-command testsuite
This should be helpful on Windows to allow running tests without
requiring Perl (for `prove`), as discussed in [1] and [2].
This again breaks backwards compatibility, as it is now required to set
TEST_SHELL_PATH properly for executing shell scripts, but again, as
noted in [2], there are no longer any such invocations in our codebase.

In the previous commit, we added support in test-tool for running
collections of unit tests. Now, add rules in t/Makefile for running in
this way.
This new rule can be executed from the top-level Makefile via
`make DEFAULT_UNIT_TEST_TARGET=unit-tests-test-tool unit-tests`, or by
setting DEFAULT_UNIT_TEST_TARGET in config.mak.

Add a wrapper script to allow `prove` to run both shell tests and unit
tests from a single invocation. This avoids issues around running prove
twice in CI, as discussed in [1].
Additionally, this moves the unit tests into the main dev workflow, so
that errors can be spotted more quickly. Accordingly, we remove the
separate unit tests step for Linux CI. (We leave the Windows CI
unit-test step as-is, because the sharding scheme there involves
selecting specific test files rather than running `make test`.)

Although the previous commit changed t/Makefile to run unit tests
alongside shell tests, the Windows CI still needs a separate unit-tests
step due to how the test sharding works.
We want to avoid using `prove` as a test running on Windows due to
performance issues [1], so use the new test-tool runner instead.

Style.
As an empty string is not a reasonable value for this variable (and
you do not quote ${TEST_SHELL_PATH} when you use it in "exec" below),
if test -z "${TEST_SHELL_PATH:+set}"
then
echo >&2 "ERROR: TEST_SHELL_PATH is not set or empty"
may be what we want here.

Other than that, the update in this iteration looks reasonable to
me.
Thanks.

For various reasons (see discussion at [1]) we would like an alternative
to `prove` for running test suites (including the unit tests) on
Windows.
[1] https://lore.kernel.org/git/pull.1613.git.1699894837844.gitgitgadget@gmail.com/
This series extends the existing `test-tool run-command testsuite` to
support running unit tests. In addition, it includes some small
cleanups:
* move t-basic out of the unit-tests directory
* don't hardcode the shell for running tests in `test-tool ... testsuite`
* don't hardcode a test name filter in `test-tool ... testsuite`
* add a test wrapper script to allow unit tests and the shell test suite
to run in a single `prove` process
Changes in V5:
* Style fix in t/run-test.sh
Changes in V4:
* Set TEST_SHELL_PATH when running the `prove` test target, and error
out of run-test.sh if TEST_SHELL_PATH is not set.
Changes in V3:
* Added new patch (#7) to use the new test-tool runner for unit tests in
Windows CI.
* Restored the explicit sort call in t/Makefile, for backwards
compatibility with older GNU Make versions.
* Rebased the series on the latest jk/unit-tests-buildfix branch.
* Fixed header include order in patch #1.
* Removed a paragraph in patch #1's commit message that is obsolete now
that we're building the list of test files from the sources rather
than by globbing.
* Added a note in patch #2 that setting a NULL suite.shell_path will be
used in a later commit.
* Clarified up some sloppy wording in commit messages and comments in
t/helper/test-run-command.c.
Changes in V2:
* Rebased the series on the latest jk/unit-tests-buildfix branch.
* Patch 1: move t-basic to a test-tool subcommand rather than a new
executable under t/t0080/
* New patch 2: get the shell path from TEST_SHELL_PATH in
`test-tool run-command testsuite`
* New patch 3: remove the hardcoded filename filter in
`test-tool run-command testsuite`
* Patch 4 (previously 2): simplified now that we no longer need to add
any command-line flags to support unit tests
* Patch 5 (previously 3): avoid trying to run cmake *.pdb files by using
the unit test list built in the makefile in jk/unit-tests-buildfix.

While t/unit-tests/t-basic.c uses the unit-test framework added in
e137fe3b29 (unit tests: add TAP unit test framework, 2023-11-09), it is
not a true unit test in that it intentionally fails in order to exercise
various codepaths in the unit-test framework. Thus, we intentionally
exclude it when running unit tests through the various t/Makefile
targets. Instead, it is executed by t0080-unit-test-output.sh, which
verifies its output follows the TAP format expected for the various
pass, skip, or fail cases.
As such, it makes more sense for t-basic to be a helper item for
t0080-unit-test-output.sh, so let's move it to
t/helper/test-example-tap.c and adjust Makefiles as necessary.

When running tests through `test-tool run-command testsuite`, we
currently hardcode `sh` as the command interpreter. As discussed in [1],
this is incorrect, and we should be using the shell set in
TEST_SHELL_PATH instead.
Add a shell_path field in struct testsuite so that we can pass this to
the task runner callback. If this is non-null, we'll use it as the
argv[0] of the subprocess. Otherwise, we'll just execute the test
program directly. We will use this feature in a later commit to enable
running binary executable unit tests.
However, for now when setting up the struct testsuite in testsuite(),
use the value of TEST_SHELL_PATH if it's set, otherwise keep the
original behavior by defaulting to `sh`.

`test-tool run-command testsuite` currently assumes that it will only be
running the shell test suite, and therefore filters out anything that
does not match a hardcoded pattern of "t[0-9][0-9][0-9][0-9]-*.sh".
Later in this series, we'll adapt `test-tool run-command testsuite` to
also support unit tests, which do not follow the same naming conventions
as the shell tests, so this hardcoded pattern is inconvenient.
Since `testsuite` also allows specifying patterns on the command-line,
let's just remove this pattern. As noted in [1], there are no longer any
uses of `testsuite` in our codebase, it should be OK to break backwards
compatibility in this case. We also add a new filter to avoid trying to
execute "." and "..", so that users who wish to execute every test in a
directory can do so without specifying a pattern.

Teach the testsuite runner in `test-tool run-command testsuite` how to
run unit tests: if TEST_SHELL_PATH is not set, run the programs directly
from CWD, rather than defaulting to "sh" as an interpreter.
With this change, you can now use test-tool to run the unit tests:
$ make
$ cd t/unit-tests/bin
$ ../../helper/test-tool run-command testsuite
This should be helpful on Windows to allow running tests without
requiring Perl (for `prove`), as discussed in [1] and [2].
This again breaks backwards compatibility, as it is now required to set
TEST_SHELL_PATH properly for executing shell scripts, but again, as
noted in [2], there are no longer any such invocations in our codebase.

In the previous commit, we added support in test-tool for running
collections of unit tests. Now, add rules in t/Makefile for running in
this way.
This new rule can be executed from the top-level Makefile via
`make DEFAULT_UNIT_TEST_TARGET=unit-tests-test-tool unit-tests`, or by
setting DEFAULT_UNIT_TEST_TARGET in config.mak.

Add a wrapper script to allow `prove` to run both shell tests and unit
tests from a single invocation. This avoids issues around running prove
twice in CI, as discussed in [1].
Additionally, this moves the unit tests into the main dev workflow, so
that errors can be spotted more quickly. Accordingly, we remove the
separate unit tests step for Linux CI. (We leave the Windows CI
unit-test step as-is, because the sharding scheme there involves
selecting specific test files rather than running `make test`.)

Although the previous commit changed t/Makefile to run unit tests
alongside shell tests, the Windows CI still needs a separate unit-tests
step due to how the test sharding works.
We want to avoid using `prove` as a test running on Windows due to
performance issues [1], so use the new test-tool runner instead.

I am OK to see it outside the scope of this series, but we would
need unit tests supported by the GIT_SKIP_TESTS mechanism (or an
alternative mechanism written), given that I hear "migrate tests to
unit-test framework" every once in a while, which means we would
accumlate more and more tests that ignore GIT_SKIP_TESTS mechansim.
I did spot one potential problem (rather, "we'd want to fix it as we
are changing it with this reroll anyway"), but other than that I did
not see anything wrong in the other patches.
Thanks. Will queue.

If we are using ":+" to handle the empty string, I think just:
if test -z "$TEST_SHELL_PATH"
is sufficient, no?
(not that the other is incorrect, but whenever I see something like
":+set" I wonder if something more clever is going on, and of course I
get nightmare flashbacks to looking at generated autoconf code).

For various reasons (see discussion at [1]) we would like an alternative
to `prove` for running test suites (including the unit tests) on
Windows.
[1] https://lore.kernel.org/git/pull.1613.git.1699894837844.gitgitgadget@gmail.com/
This series extends the existing `test-tool run-command testsuite` to
support running unit tests. In addition, it includes some small
cleanups:
* move t-basic out of the unit-tests directory
* don't hardcode the shell for running tests in `test-tool ... testsuite`
* don't hardcode a test name filter in `test-tool ... testsuite`
* add a test wrapper script to allow unit tests and the shell test suite
to run in a single `prove` process
Changes in V4:
* Set TEST_SHELL_PATH when running the `prove` test target, and error
out of run-test.sh if TEST_SHELL_PATH is not set.
Changes in V3:
* Added new patch (#7) to use the new test-tool runner for unit tests in
Windows CI.
* Restored the explicit sort call in t/Makefile, for backwards
compatibility with older GNU Make versions.
* Rebased the series on the latest jk/unit-tests-buildfix branch.
* Fixed header include order in patch #1.
* Removed a paragraph in patch #1's commit message that is obsolete now
that we're building the list of test files from the sources rather
than by globbing.
* Added a note in patch #2 that setting a NULL suite.shell_path will be
used in a later commit.
* Clarified up some sloppy wording in commit messages and comments in
t/helper/test-run-command.c.
Changes in V2:
* Rebased the series on the latest jk/unit-tests-buildfix branch.
* Patch 1: move t-basic to a test-tool subcommand rather than a new
executable under t/t0080/
* New patch 2: get the shell path from TEST_SHELL_PATH in
`test-tool run-command testsuite`
* New patch 3: remove the hardcoded filename filter in
`test-tool run-command testsuite`
* Patch 4 (previously 2): simplified now that we no longer need to add
any command-line flags to support unit tests
* Patch 5 (previously 3): avoid trying to run cmake *.pdb files by using
the unit test list built in the makefile in jk/unit-tests-buildfix.

While t/unit-tests/t-basic.c uses the unit-test framework added in
e137fe3b29 (unit tests: add TAP unit test framework, 2023-11-09), it is
not a true unit test in that it intentionally fails in order to exercise
various codepaths in the unit-test framework. Thus, we intentionally
exclude it when running unit tests through the various t/Makefile
targets. Instead, it is executed by t0080-unit-test-output.sh, which
verifies its output follows the TAP format expected for the various
pass, skip, or fail cases.
As such, it makes more sense for t-basic to be a helper item for
t0080-unit-test-output.sh, so let's move it to
t/helper/test-example-tap.c and adjust Makefiles as necessary.

When running tests through `test-tool run-command testsuite`, we
currently hardcode `sh` as the command interpreter. As discussed in [1],
this is incorrect, and we should be using the shell set in
TEST_SHELL_PATH instead.
Add a shell_path field in struct testsuite so that we can pass this to
the task runner callback. If this is non-null, we'll use it as the
argv[0] of the subprocess. Otherwise, we'll just execute the test
program directly. We will use this feature in a later commit to enable
running binary executable unit tests.
However, for now when setting up the struct testsuite in testsuite(),
use the value of TEST_SHELL_PATH if it's set, otherwise keep the
original behavior by defaulting to `sh`.

`test-tool run-command testsuite` currently assumes that it will only be
running the shell test suite, and therefore filters out anything that
does not match a hardcoded pattern of "t[0-9][0-9][0-9][0-9]-*.sh".
Later in this series, we'll adapt `test-tool run-command testsuite` to
also support unit tests, which do not follow the same naming conventions
as the shell tests, so this hardcoded pattern is inconvenient.
Since `testsuite` also allows specifying patterns on the command-line,
let's just remove this pattern. As noted in [1], there are no longer any
uses of `testsuite` in our codebase, it should be OK to break backwards
compatibility in this case. We also add a new filter to avoid trying to
execute "." and "..", so that users who wish to execute every test in a
directory can do so without specifying a pattern.

Teach the testsuite runner in `test-tool run-command testsuite` how to
run unit tests: if TEST_SHELL_PATH is not set, run the programs directly
from CWD, rather than defaulting to "sh" as an interpreter.
With this change, you can now use test-tool to run the unit tests:
$ make
$ cd t/unit-tests/bin
$ ../../helper/test-tool run-command testsuite
This should be helpful on Windows to allow running tests without
requiring Perl (for `prove`), as discussed in [1] and [2].
This again breaks backwards compatibility, as it is now required to set
TEST_SHELL_PATH properly for executing shell scripts, but again, as
noted in [2], there are no longer any such invocations in our codebase.

In the previous commit, we added support in test-tool for running
collections of unit tests. Now, add rules in t/Makefile for running in
this way.
This new rule can be executed from the top-level Makefile via
`make DEFAULT_UNIT_TEST_TARGET=unit-tests-test-tool unit-tests`, or by
setting DEFAULT_UNIT_TEST_TARGET in config.mak.

Add a wrapper script to allow `prove` to run both shell tests and unit
tests from a single invocation. This avoids issues around running prove
twice in CI, as discussed in [1].
Additionally, this moves the unit tests into the main dev workflow, so
that errors can be spotted more quickly. Accordingly, we remove the
separate unit tests step for Linux CI. (We leave the Windows CI
unit-test step as-is, because the sharding scheme there involves
selecting specific test files rather than running `make test`.)

Although the previous commit changed t/Makefile to run unit tests
alongside shell tests, the Windows CI still needs a separate unit-tests
step due to how the test sharding works.
We want to avoid using `prove` as a test running on Windows due to
performance issues [1], so use the new test-tool runner instead.

Ack. I think the current GIT_SKIP_TESTS system should be fine. I'll put
it on my TODO but can't promise that it will be a priority yet.
