Build dependency around unit tests has been fixed.
* jk/unit-tests-buildfix:
t/Makefile: say the default target upfront
t/Makefile: get UNIT_TESTS list from C sources
Makefile: remove UNIT_TEST_BIN directory with "make clean"
Makefile: use mkdir_p_parent_template for UNIT_TEST_BIN
|
|
The priority queue test has been migrated to the unit testing
framework.
* cp/unit-test-prio-queue:
tests: move t0009-prio-queue.sh to the new unit testing framework
|
|
The Makefile often had to say "-L$(path) -R$(path)" that repeats
the path to the same library directory for link time and runtime.
A Makefile template is used to reduce such repetition.
* jc/make-libpath-template:
Makefile: simplify output of the libpath_template
Makefile: reduce repetitive library paths
|
|
When we take a library package we depend on (e.g., LIBPCRE) from a
directory other than the default location of the system, we add the
same directory twice on the linker command like, like so:
EXTLIBS += -L$(LIBPCREDIR)/$(lib) $(CC_LD_DYNPATH)$(LIBPCREDIR)/$(lib)
Introduce a template "libpath_template" that takes the path to the
directory, which can be used like so:
EXTLIBS += $(call libpath_template,$(LIBPCREDIR)/$(lib))
and expand it into the "-L$(DIR) $(CC_LD_DYNPATH)$(DIR)" form.
Hopefully we can reduce the chance of typoes this way.

We remove $(UNIT_TEST_PROGS), but that leaves the automatically
generated "bin" dir they reside in. And once we start cleaning that,
there is no point in removing the individual programs, as they'll by
wiped out by the recurse "rm".

We build the UNIT_TEST_BIN directory (t/unit-tests/bin) on the fly with
"mkdir -p". And so the recipe for UNIT_TEST_PROGS, which put their
output in that directory, depend on UNIT_TEST_BIN to make sure it's
there.
But using a normal dependency leads to weird outcomes, because the
timestamp of the directory is important. For example, try this:
$ make
[...builds everything...]
[now re-build one unit test]
$ touch t/unit-tests/t-ctype.c
$ make
SUBDIR templates
CC t/unit-tests/t-ctype.o
LINK t/unit-tests/bin/t-ctype
So far so good. Now running make again should build nothing. But it
doesn't!
$ make
SUBDIR templates
LINK t/unit-tests/bin/t-basic
LINK t/unit-tests/bin/t-mem-pool
LINK t/unit-tests/bin/t-strbuf
Er, what? Let's rebuild again:
$ make
SUBDIR templates
LINK t/unit-tests/bin/t-ctype
Weird. And now we ping-pong back and forth forever:
$ make
SUBDIR templates
LINK t/unit-tests/bin/t-basic
LINK t/unit-tests/bin/t-mem-pool
LINK t/unit-tests/bin/t-strbuf
$ make
SUBDIR templates
LINK t/unit-tests/bin/t-ctype
What happens is that writing t/unit-tests/bin/t-ctype updates the mtime
of the directory t/unit-tests/bin. And then on the next invocation of
make, all of those other tests are now older and so get rebuilt. And
back and forth forever.
We can fix this by making the directory as part of the build recipe for
the programs, using the template from 0b6d0bc924 (Makefiles: add and use
wildcard "mkdir -p" template, 2022-03-03).

To prevent bitrot, we would like to regularly exercise the fuzz tests in
order to make sure they still link & run properly. We already compile
the fuzz test objects as part of the default `make` target, but we do
not link the executables due to the fuzz tests needing specific
compilers and compiler features. This has lead to frequent build
breakages for the fuzz tests.
To remedy this, we can add a CI step to actually link the fuzz
executables, and run them (with finite input rather than the default
infinite random input mode) to verify that they execute properly.
Since the main use of the fuzz tests is via OSS-Fuzz [1], and OSS-Fuzz
only runs tests on Linux [2], we only set up a CI test for the fuzzers
on Linux.

When we originally added the fuzz tests in 5e47215080 (fuzz: add basic
fuzz testing target., 2018-10-12), we went to some trouble to create a
Makefile rule that allowed linking the fuzz executables without pulling
in common-main.o. This was necessary to prevent the
fuzzing-engine-provided main() from clashing with Git's main().
However, since 19d75948ef (common-main.c: move non-trace2 exit()
behavior out of trace2.c, 2022-06-02), it has been necessary to link
common-main.o due to moving the common_exit() function to that file.
Ævar suggested a set of compiler flags to allow this in [1], but this
was never reflected in the Makefile.
Since we now must include common-main.o, there's no reason to pick and
choose a subset of object files to link, so simplify the Makefile rule
for the fuzzer executables to just use libgit.a. While we're at it,
include the necessary linker flag to allow multiple definitions
directly in the Makefile rule, rather than requiring it to be passed on
the command-line each time. This means the Makefile rule as written is
now more compiler-specific, but this was already the case for the
fuzzers themselves anyway.

In the recent codebase update (8bf6fbd00d (Merge branch
'js/doc-unit-tests', 2023-12-09)), a new unit testing framework was
merged, providing a standardized approach for testing C code. Prior to
this update, some unit tests relied on the test helper mechanism,
lacking a dedicated unit testing framework. It's more natural to perform
these unit tests using the new unit test framework.
This commit migrates the unit tests for C character classification
functions (isdigit(), isspace(), etc) from the legacy approach
using the test-tool command `test-tool ctype` in t/helper/test-ctype.c
to the new unit testing framework (t/unit-tests/test-lib.h).
The migration involves refactoring the tests to utilize the testing
macros provided by the framework (TEST() and check_*()).

Memory pool allocations that require a new block and would fill at
least half of it are handled specially. Before 158dfeff3d (mem-pool:
add life cycle management functions, 2018-07-02) they used to be
allocated outside of the pool. This patch made mem_pool_alloc() create
a bespoke block instead, to allow releasing it when the pool gets
discarded.
Unfortunately mem_pool_alloc() returns a pointer to the start of such a
bespoke block, i.e. to the struct mp_block at its top. When the caller
writes to it, the management information gets corrupted. This affects
mem_pool_discard() and -- if there are no other blocks in the pool --
also mem_pool_alloc().
Return the payload pointer of bespoke blocks, just like for smaller
allocations, to protect the management struct.
Also update next_free to mark the block as full. This is only strictly
necessary for the first allocated block, because subsequent ones are
inserted after the current block and never considered for further
allocations, but it's easier to just do it in all cases.
Add a basic unit test to demonstrate the issue by using
mem_pool_calloc() with a tiny block size, which forces the creation of a
bespoke block.

When building executables we may end up with both `foo` and `foo.exe` in
the project's root directory. This can cause issues on Cygwin, which is
why we unlink the `foo` binary (see 6fc301bbf68 (Makefile: remove $foo
when $foo.exe is built/installed., 2007-01-10)). This step is skipped if
either:
- `foo` is a directory, which can happen when building Git on
Windows via MSVC (see ade2ca0ca9f (Do not try to remove
directories when removing old links, 2009-10-27)).
- `foo` is a hardlink to `foo.exe`, which can happen on Cygwin (see
0d768f7c8f1 (Makefile: building git in cygwin 1.7.0, 2008-08-15)).
These two conditions are currently chained together via `test -o`, which
is discouraged by our code style guide. Convert the recipe to instead
use an `if` statement with `&&`'d conditions, which both matches our
style guide and is easier to ready.

As of recent, Git also builds executables in `t/unit-tests/`. For
technical reasons, when building with CMake and Visual C, the
dependencies (".dll files") need to be copied there, too, otherwise
running the executable will fail "due to missing dependencies".
The CMake definition already contains the directives to copy those
`.dll` files, but we also need to adjust the `artifacts-tar` rule in
the `Makefile` accordingly to let the `vs-test` job in the CI runs
pass successfully.

This patch contains an implementation for writing unit tests with TAP
output. Each test is a function that contains one or more checks. The
test is run with the TEST() macro and if any of the checks fail then the
test will fail. A complete program that tests STRBUF_INIT would look
like
#include "test-lib.h"
#include "strbuf.h"
static void t_static_init(void)
{
struct strbuf buf = STRBUF_INIT;
check_uint(buf.len, ==, 0);
check_uint(buf.alloc, ==, 0);
check_char(buf.buf[0], ==, '\0');
}
int main(void)
{
TEST(t_static_init(), "static initialization works);
return test_done();
}
The output of this program would be
ok 1 - static initialization works
1..1
If any of the checks in a test fail then they print a diagnostic message
to aid debugging and the test will be reported as failing. For example a
failing integer check would look like
# check "x >= 3" failed at my-test.c:102
# left: 2
# right: 3
not ok 1 - x is greater than or equal to three
There are a number of check functions implemented so far. check() checks
a boolean condition, check_int(), check_uint() and check_char() take two
values to compare and a comparison operator. check_str() will check if
two strings are equal. Custom checks are simple to implement as shown in
the comments above test_assert() in test-lib.h.
Tests can be skipped with test_skip() which can be supplied with a
reason for skipping which it will print. Tests can print diagnostic
messages with test_msg(). Checks that are known to fail can be wrapped
in TEST_TODO().
There are a couple of example test programs included in this
patch. t-basic.c implements some self-tests and demonstrates the
diagnostic output for failing test. The output of this program is
checked by t0080-unit-test-output.sh. t-strbuf.c shows some example
unit tests for strbuf.c
The unit tests will be built as part of the default "make all" target,
to avoid bitrot. If you wish to build just the unit tests, you can run
"make build-unit-tests". To run the tests, you can use "make unit-tests"
or run the test binaries directly, as in "./t/unit-tests/bin/t-strbuf".

The index file has room only for lower 32-bit of the file size in
the cached stat information, which means cached stat information
will have 0 in its sd_size member for a file whose size is multiple
of 4GiB. This is mistaken for a racily clean path. Avoid it by
storing a bogus sd_size value instead for such files.

t: add a test helper to truncate files
|
|
In a future commit, we're going to work with some large files which will
be at least 4 GiB in size. To take advantage of the sparseness
functionality on most Unix systems and avoid running the system out of
disk, it would be convenient to use truncate(2) to simply create a
sparse file of sufficient size.
However, the GNU truncate(1) utility isn't portable, so let's write a
tiny test helper that does the work for us.

On Windows, there are two kinds of executables, console ones and
non-console ones. Git's executables are all console ones.
When launching the former e.g. in a scheduled task, a CMD window pops
up. This is not what we want for the tasks installed via the `git
maintenance` command.
To work around this, let's introduce `headless-git.exe`, which is a
non-console program that does _not_ pop up any window. All it does is to
re-launch `git.exe`, suppressing that console window, passing through
all command-line arguments as-are.

A long term (but rather minor) pet-peeve of mine was the name
ll-merge.[ch]. I thought it made it harder to realize what stuff was
related to merging when I was working on the merge machinery and trying
to improve it.
Further, back in d1cbe1e6d8a ("hash-ll.h: split out of hash.h to remove
dependency on repository.h", 2023-04-22), we have split the portions of
hash.h that do not depend upon repository.h into a "hash-ll.h" (due to
the recommendation to use "ll" for "low-level" in its name[1], but which
I used as a suffix precisely because of my distaste for "ll-merge").
When we discussed adding additional "*-ll.h" files, a request was made
that we use "ll" consistently as either a prefix or a suffix. Since it
is already in use as both a prefix and a suffix, the only way to do so
is to rename some files.
Besides my distaste for the ll-merge.[ch] name, let me also note that
the files
ll-fsmonitor.h, ll-hash.h, ll-merge.h, ll-object-store.h, ll-read-cache.h
would have essentially nothing to do with each other and make no sense
to group. But giving them the common "ll-" prefix would group them. Using
"-ll" as a suffix thus seems just much more logical to me. Rename
ll-merge.[ch] to merge-ll.[ch] to achieve this consistency, and to
ensure we get a more logical grouping of files.

Note that compat/fsmonitor/fsm-path-utils-darwin.c previously got
away with violating the rule that all files must start with an include
of git-compat-util.h (or a short-list of alternate headers that happen
to include it first). This change exposed the violation and caused it
to stop building correctly; fix it by having it include

accent which is rendered as ' in ASCII, but as ´ in utf-8.
This started a cascade of bug reports in git [2], debian [3], Arch Linux
[4], docbook itself [5], and probably many others.
A solution was to use the correct groff character: \(aq, which is always
rendered as ', but the problem is that such character doesn't work in
other troff programs.
A portable solution required the use of a conditional character that is
\(aq in groff, but ' in all others:
.ie \n(.g .ds Aq \(aq
.el .ds Aq '
The proper solution took time to be implemented in docbook, but in 2010
they did it [6]. So the docbook man page stylesheets were broken from
1.73 to 1.76.
Unfortunately by that point many workarounds already existed. In the
case of git, GNU_ROFF was introduced, and in the case of Arch Linux
a mapping from \' to ' was added to groff's man.local. Other
distributions might have done the same, or similar workarounds.
Since 2010 there is no need for this workaround, which is fixed
elsewhere, not just in docbook, but other layers as well.
Let's remove it.

Since [1] first released with Git v2.37.0 the built-in version of "add
-i" has been the default. That built-in implementation was added in
[2], first released with Git v2.25.0.
At this point enough time has passed to allow for finding any
remaining bugs in this new implementation, so let's remove the
fallback code.
As with similar migrations for "stash"[3] and "rebase"[4] we're
keeping a mention of "add.interactive.useBuiltin" in the
documentation, but adding a warning() to notify any outstanding users
that the built-in is now the default. As with [5] and [6] we should
follow-up in the future and eventually remove that warning.

Newer regex library macOS stopped enabling GNU-like enhanced BRE,
where '\(A\|B\)' works as alternation, unless explicitly asked with
the REG_ENHANCED flag. "git grep" now can be compiled to do so, to
retain the old behaviour.

Remove "git env--helper" and demote it to a test-tool subcommand.
* ab/test-env-helper:
env-helper: move this built-in to "test-tool env-helper"

Since [1] there has been no reason for keeping "git env--helper" a
built-in. The reason it was a built-in to begin with was to support
the GIT_TEST_GETTEXT_POISON mode removed in that commit. I.e. unlike
the rest of "test-tool" it would potentially be called by the
installed git via "git-sh-i18n.sh".
As none of that applies since [1] we should stop carrying this
technical debt, and move it to t/helper/*. As this mostly move-only
change shows this has the nice bonus that we'll stop wasting time
translating the internal-only strings it emits.
Even though this was a built-in, it was intentionally never
documented, see its introduction in [2]. It never saw use outside of
the test suite, except for the "GIT_TEST_GETTEXT_POISON" use-case
noted above.
