In most cases, like math, we want C-semantics for floating point
numbers. In particular "." needs to be the decimal separator.
Instead, we pay the price in printf, which is currently the sole place
to output in locale-specific numbers and attempt to read them and
C-style ones.
- Only check for HAVE_CLOCK_GETTIME and HAVE_FUTIMENS on Linux, since
they are only used to implement a Linux-specific workaround related
to mtime precision.
- Make sure that hack is limited to Linux builds
- HAVE_SYS_SYSCTL_H was unused, but we should have been using it
- HAVE_TERMIOS_H was unused, remove it
The only functional change is that unix machines with clock_gettime
and futimens will not bother with a Linux-specific hack, and won't
waste time checking for either during cmake configuration either.
sphinx-build supports the -j option to use multiple processes. Start using
it. This reduces the time to build the docs on my Linux box from 11 seconds
to about 4.
Note this doesn't work on macOS since -j is ignored there (see sphinx-build
PR 6879).
This lets us run non-fish targets (such as `fish_tests`) under a clean
test environment without running into the fish-specific payload
configuration now carried out by `test_driver.sh` which expects a
`.fish` payload that it will run under a deterministically configured
instance of fish, running in an environment initialized by
`test_env.sh`.
This should fix the problem with in-tree builds leaving detritus behind
after a `make test` when `fish_tests` would be executed without
`test_driver.sh` - it is now executed under `test_env.sh` instead.
For littlecheck/pexpect this just unconditionally enables color.
I have no idea what happens if you run cmake outside of a terminal
, but the worst that can happen is that *errors* have color
escapes in them.
If someone figures out how to get cmake to tell us if it's running in
a terminal, we can add a check.
This means instead of printing at least two lines per successful test,
we overwrite one line again and again with the current status, and
for *failed* (i.e interesting) tests we print the output.
Makes test failures much more visible.
`test:foo` is not allowed by CMake ("reserved name") and `test/foo`
won't work since CMake doesn't allow targets to have a directory
separator in their name.
Even though we are using CMake's ctest for testing, we still define our
own `make test` target rather than use its default for many reasons:
* CMake doesn't run tests in-proc or even add each tests as an
individual node in the ninja dependency tree, instead it just bundles
all tests into a target called `test` that always just shells out to
`ctest`, so there are no build-related benefits to not doing that
ourselves.
* CMake devs insist that it is appropriate for `make test` to never
depend on `make all`, i.e. running `make test` does not require any
of the binaries to be built before testing.
* The only way to have a test depend on a binary is to add a fake test
with a name like "build_fish" that executes CMake recursively to
build the `fish` target.
* It is not possible to set top-level CTest options/settings such as
CTEST_PARALLEL_LEVEL from within the CMake configuration file.
* Circling back to the point about individual tests not being actual
Makefile targets, CMake does not offer any way to execute a named
test via the `make`/`ninja`/whatever interface; the only way to
manually invoke test `foo` is to to manually run `ctest` and specify
a regex matching `foo` as an argument, e.g. `ctest -R ^foo$`... which
is really crazy.
With this patch, it is now possible to execute any single test by name,
by invoking the build directly, e.g. to run the `universal.fish` check:
`cmake --build build --target universal.fish` or
`ninja -C build universal.fish`. Unfortunately, this is not integrated
into the Makefile wrapper, so `make universal.fish` won't work (although
this can potentially be hacked around).
Instead of compiling `fish_tests.cpp` dynamically with weakly-linked
symbols and asking it to print the list of all available tests, we
use a magic string `#define`'d as a no-op to allow CMake to regex search
for matching test groups. This speeds up configuration somewhat (by not
compiling anything), but more importantly, it's much less brittle and
doesn't involve and linker dark magic.
There's of course still no getting around the fact that it's really ugly.
* Remove safe_strerror, safe_perror and safe_append
This no longer works on new glibcs because they removed sys_errlist.
So just hardcode the relevant errno messages (and phrase them better).
Fixes#4183.

Cmake accepts both absolute and relative paths in CMAKE_INSTALL_DATADIR.
For the latter case CMAKE_INSTALL_PREFIX is being prepended
automatically. %{rel_datadir} is derived from CMAKE_INSTALL_DATADIR
which was assumed to be relative and otherwise causes issues in a .pc
file where prefix is being prepended unconditionally.
Make sure %{rel_datadir} is relative by calculating RELATIVE_PATH from
CMAKE_INSTALL_PREFIX to CMAKE_INSTALL_FULL_DATADIR which is known to be
absolute.
Fixes#8150
This has cheesy pattern matching that I'm not entirely sure adds
anything?
Surely if we add something to share/web_config that should be
installed *by default*?
Anyway, let's just add .theme to it
Previously, both fish.pc and libfish had generating the
FISH-BUILD-VERSION-FILE attached as a command. In principle they could
both try to run the command simultaneously and now CMake complains about
this with the Xcode generator.
Switch to having fish.pc depend on the CHECK-FISH-BUILD-VERSION-FILE as a
target instead of a command. This allows it to participate in dependency
resolution and CMake will succeed again.
Fixes#7838
When executing “make test -jX” (with X > 1) to build and run tests in a
build directory, there is a race condition between the
serial_test_low_level target and the test_prep target (a dependency of
serial_test_fishscript and serial_test_interactive).
As far as I can tell, these events happen in a serial build scenario
(“make test” with the “Unix Makefiles” CMake generator):
1. The fish_tests binary is built and executed.
2. The test_prep target (a dependency of serial_test_fishscript)
cleans up test directories.
3. Tests in test.fish are executed.
In a parallel build scenario, this often happens:
1. Build of the fish_tests binary is started.
2. The test_prep target cleans up test directories.
3. Build of the fish_tests binary is finished.
4. Execution of the fish_tests binary starts.
5. Execution of the fish_tests binary finishes.
6. Tests in test.fish are executed.
However, if building the fish_tests binary is fast enough but not
instant (e.g. when using ccache), this can happen:
1. Build of the fish_tests binary is started.
2. Build of the fish_tests binary is finished.
3. Execution of the fish_tests binary starts.
4. The test_prep target cleans up test directories.
5. fish_tests tests that depend on said test directories may,
depending on timing, fail because they are wiped by test_prep.
Fix this by making test_prep a dependency of serial_test_low_level so
that test_prep can’t interfere with fish_tests execution.
The only thing we know ever triggered this is old macOS versions,
there's no need to use it for everyone else.
Since this uses try_run it breaks when cross-compiling, which
shouldn't be a common thing on macOS.
Fixes#7737
This is far preferable to the per-test XDG overrides that we may or may
not remember to add the next time around.
Also rename all the directories so it is clear via which variable a file
made its way into that path.
This was a typo. CMake doesn't take comma-separated arguments, but if
you do add the comma it tends to work, because it just takes that
comma as part of the string. So if it takes a directory to work in,
that it will then create, and you pass
${CMAKE_CURRENT_BINARY_DIR},
well, that might just create a "build," directory.
fish wants to build with -mmacosx-version-min=10.9. This is important
because it ensures that we do not use functions or linker features which
which are not available on 10.9. However this collides with the fact
that fish also prefers to use a pcre2 package installed on the system,
which is typically built for that system.
Mac ld will (rightly) complain when it sees a 10.9-targeted binary
linking a 10.15-targeted dylib. This is an annoying warning that gets
emitted on every build.
We could fix this either having Mac builds prefer the vendored PCRE2
by default, or by having debug builds target the system version. But
we want to continue to default to system PCRE2 and we don't want to risk
losing compatibility with older Mac versions. So we will just suppress
all linker warnings in Mac debug builds.
It's not entirely clear why the existing check does not work, but it seems to pass on clang++ even without -latomic, but causes the fish build to fail later.
Confirmed that with this change, g++ does not use -latomic, while clang++ does, and fish builds fine with both.
When CMake's own curses logic fails to find curses/ncurses, we fall back to
pkg-config and manually link the required libraries. Some platforms (RHEL 6,
see #6587) require CURSES_EXTRA_LIBRARY=tinfo, so we link against libtinfo
if it's found but are happy to continue without it if it doesn't exist.
Closes#6587
This adds a new interactive test framework based on Python's pexpect. This
is intended to supplant the TCL expect-based tests.
New tests go in `tests/pexpects/`. As a proof-of-concept, the
pipeline.expect test and the (gnarly) bind.expect test are ported to the
new framework.
The CMake variable FISH_USE_SYSTEM_PCRE2 now controls whether fish uses
system PCRE2 or the bundled version. The default is to use the system
version, unless no such version is found, or unless it is a macOS build
with code signing. Note the default behavior has not changed.
Fixes#6952
This allows all variables to be set properly when the prefix or datadir changes.

Building on OS X versions prior to 10.13.6 fails at the very end when
running `codesign`.
The `-options runtime`-argument isn't available on these earlier
versions of the OS.
Simply running codesign without that argument (on OS X <10.13.6) seems
to produce a runnable binary with no security warnings.
- Define it before the headers so they can pick the variadic tparm
prototype.
- We need a TPARM_VARARGS define, add it to config_cmake.h.
- Move & adjust comment - put it near the code, and mentiont that
NetBSD curses doesn't need the kludge.
Now variadic tparm is used on NetBSD instead of the Solaris kludge.
Perform an ad-hoc code signing with the hardened runtime.
This ensures that these executables can pass notarization.
The code signing ID is controlled by the MAC_CODESIGN_ID CMake
cache variable.
This commit updates PCRE2 to 10.34, and we no longer include what's in their
tarball as-is. I've yanked out a lot of uneccessary stuff for the sake of the
size of our codebase.
original pcre2-10.34 dir: 11.5MB
pcre2 dir in this commit: 1.6MB
* Remove documentation, makefiles, test suites, etc. LICENSE remains.
* Disable building tests when configuring PCRE2
* Yard out JIT support: delete src/jit, src/pcre2_jit_*.c, and code doing
stuff to code->executable_jit that needs a jit header (it was already NULL
because we've always built with JIT disabled).
* Remove most .c and .h files not needed to compile: pcre2grep code,
pcre2test code, dftables.c, pcre2_printint.c, pcre2_fuzzsupport.c ...
* Remove FindBZip2, FindZLIB, FindReadline, FindEditline. These were used
only by pcre2grep and made CMake's report misleading with regard to
optional packages being used.
* Remove configure.ac except for version number and date which CMake checks
Next time we update PCRE2, refer to this commit message as well as a diff
between pcre2-10.34.tar.gz and ./pcre2-10.34/. Or better yet, cease including
pcre2.
$XDG_DATA_DIRS/vendor_{completions,conf,functions}.d
Additionally, CMake variables extra_{completions,conf,functions}dir are
appended, if they are not already contained in $XDG_DATA_DIRS.
If XDG_DATA_DIRS is not defined, we fall back to
$__fish_datadir/vendor_completions.d:${extra_completionsdir}
for completions. Same for conf and functions.
Two blocks of code were trying to do the same thing in different ways;
standardise on one, and only add the compile flags if CMake won't do it
itself (policy CMP0067).
Work around the issue in CMake where C++ standard doesn't get propagated
to CHECK_CXX_SOURCE_COMPILES. Also correctly check for std::make_unique;
the define was missing from the config.h header.
GCC 4.8 requires the use of `-std=gnu++11` or similar to enable atomic
features. However, older versions of CMake don't pick up the
project-wide target for C++11 when building the configure check targets.
Although CMake policy 0067 could be set to NEW to enable this, it only
exists on CMake 3.8 and newer, while many of our supported platforms are
on an older version.
780bac671f did not actually successfully
compile on any platforms, leading to -latomic always being added
(including on platforms it does not exist on).
Work on #5865.
This makes test_low_level, test_interactive, test_invocation, and
test_fishscript independent. This allows running a smaller subset of tests.
To prevent all tests running in parallel, we also have new targets
serial_test_low_level, serial_test_interactive, etc. which have the
dependency chain that enforces serial execution.
This adds support for .check files inside the tests directory. .check
files are tests designed to be run with littlecheck.
Port printf test to littlecheck and remove the printf.in test.
This adds an option --print-rusage-self to the fish executable. When set,
this option prints some getrusage stats to the console in a human-readable
way. This will be used by upcoming benchmarking support.
In tests we would like to arrange for an executable to invoke certain
system calls, e.g. to claim or relinquish control of the terminal. This is
annoying to do portably via e.g. perl. fish_test_helper is a little
program where we can add custom commands to make it act in certain ways.

That tried to fix problems with pkgconfig by not recreating it.
Instead, use the function we already have for not trying too hard to
create a directory.
Fixes#5735.
The compiler flag `-Werror=unguarded_availability` was hard-coded for
macOS, but is not supported by GCC on macOS 10.10 (Yosemite). Test for
support with CHECK_CXX_COMPILER_FLAG before forcing it.
This was broken in a8eb02f9f5 when the
detection was corrected for FreeBSD. This patch makes the detection work
for both Linux and FreeBSD instead of one or the other (tested).
CMake seems to have trouble finding libraries from multiarch packages
that do not have the compatibility symlink installed to the
arch-independent library directory. Users must either manually supply
the path to the library in question via command-line parameters or we
can fall back to CMake's alternate method of finding packages based off
of pkg-config rather than using the hard-coded `FindCurses` CMake module
specific to the CMake version/distribution installed.
Just sets locale to "C" (because that's the only one we need), does
wcstod and resets the locale.
No idea why uselocale(loc) failed for me, but it did.
Fixes#5407.
This fixes a variety of issues related to building the documentation
with CMake. In particular it cleans up the dependency management and
fixes some issues where the documentation build was using generated
files from the source directory.
fish's cmake install routines were attempting to create system
directories that already existed, an operation for which the permissions
to do so may not be available (e.g. /usr/local/share/pkgconfig)
This commit first checks if a directory exists before creating it.
Homebrew and other systems set the path for the extra completion,
function and configuration directories outside the writeable prefix.
Mirror the autotools build in trying to create these directories, but
not causing the whole install to fail if this operation in unsuccessful.
The custom command for fish.pc had a dependency on FBVF, but it appears
that the relative path to FBVF was incorrect and with CMake 3.10.1 under
FreeBSD this was consistently causing the build to fail if
../build_tools/git_version_gen.sh hadn't (coincidentally, I think?)
already run.
Explicitly set the dependency path for FBVF to the binary directory.
The custom command for fish.pc had a dependency on FBVF, but there was
no cmake rule for the generation of the FBVF file. With CMake 3.10.1
under FreeBSD, this was consistently causing the build to fail if
../build_tools/git_version_gen.sh hadn't (coincidentally, I think?)
already run.
The non-ncurses version of term.h requires that curses.h be first
included. Only very recent versions of CMake include a LANGUAGE
option to CHECK_INCLUDE_FILES, so we aren't using it and specifying
CXX here..
