John Ericson 9b9ecdee34 Simplify RapidCheck configure
No more `RAPIDCHECK_HEADERS`!
2024-01-15 08:05:05 -05:00
John Ericson 2cea88dbc8 Improve build sytem support for readline instead of editline
Changes:

- CPP variable is now `USE_READLINE` not `READLINE`

- `configure.ac` supports with new CLI flag

- `package.nix` supports with new configuration option

- `flake.nix` CIs this (along with no markdown)

Remove old Ubuntu 16.04 stop-gap too, as that is now quite old.

Motivation:

- editline does not build for Windows, but readline *should*. (I am
  still working on this in Nixpkgs at this time, however. So there will
  be a follow-up Nix PR removing the windows-only skipping of the
  readline library once I am done.)

- Per
  https://salsa.debian.org/debian/nix/-/blob/master/debian/rules?ref_type=heads#L27
  and #2551, Debian builds Nix with readline. Now we better support and
  CI that build configuration.

This is picking up where #2551 left off, ensuring we test a few more
things not merely have CPP for them.

John Ericson 7feabf7d44 Split --disable-tests, fix cross builds
It might seem obnoxious to have yet more configure flags, but I found
controlling both the unit and functional tests with one flag was quite
confusing because they are so different:

- unit tests depending on building, functional tests don't (e.g. when
  we test already-built Nix)

- unit tests can be installed, functional tests cannot

- unit tests neeed extra libraries (GTest, RapidCheck), functional
  tests need extra executables (jq).

- unit tests are run by `make check`, functional tests are run by `make
  installcheck`

Really on a technical level, they seem wholly independent. Only on a
human level ("they are both are tests") do they have anything in common.

I had messed up the logic in cross builds because of this. Now I
split the flag in two (and cleaned up a few other inconsistencies), and
the logic fixed itself.

John Ericson e13fc0bbdb Fix sys/xattr.h check
I wrote the `configure.ac` wrong, and so we just got no builds
supporting ACLs.

Also, it needs to be more precise because Darwin puts other stuff in
that same header, evidently.

John Ericson a7115a47ef Improve ACL clearing support (fixing FreeBSD build)
The problem was that f880469173 forgot
that the `#include <sys/xattr.h>` was guarded by an `#ifdef __linux__`.

However, the build failure was only on FreeBSD --- turns out other
platforms have this header too!

The fix therefore uses a new configure check so we properly clear ACLs
on more platforms.

John Ericson 6c8f4ef350 Allow installing unit tests
Closes #9343

See that issue for motivation.

Installing these is disabled by default, but we enable it (and the
additional output we want isntall these too so as not to clutter the
existing ones) to use in cross builds and dev shells.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80431

(test is adapted from issue, test does not test for GCC-specific
behavior but rather absence of bug, so test is good with other compilers
too.)

John Ericson 47b3508665 Use positive source filtering for the standalone functional tests job
Additionally this skipping of the building is reimplemented to be a bit
more robust and use the same idioms as the functionality for skipping
the tests. In particular, it will now work even if the source files
exist, so we can do this during development too.

John Ericson 6910f5dcb6 Generate API docs with Doxygen
The motivation is as stated in issue #7814: even though the the C++ API
is internal and unstable, people still want it to be well documented for
sake of learning, code review, and other purposes that aren't predicated
on it being stable.

Fixes #7814

Robert Hensing 8648ebc2cc Add ./configure --disable-tests option
Building without tests is useful for bootstrapping with a smaller footprint
or running the tests in a separate derivation. Otherwise, we do compile and
run them.

This isn't fine grained as to allow picking `check` but not `installcheck`
or vice versa, but it's good enough for now.

I've tried to use Nixpkgs' `checkInputs`, but those inputs weren't discovered
properly by the configure script. We can emulate its behavior very well though.

John Ericson 16fa8c2e0e Fix configure.ac rapidcheck tests
- `AC_LANG_PUSH(C++)` is needed for the header check

- The library check is hopeless (without lots of third-party macros I
  don't feel like getting) because name mangling

Pkg-config would make all this easier. I previously opened
https://github.com/emil-e/rapidcheck/issues/302, I should write a PR
too.

Théophane Hufschmitt d1cda07ce4 Don't use -load_all on darwin
That flag breaks `-lc++fs` (introducing a duplicate symbol for some
reason). Besides, it was apparently needed for bzip2, but we're not using bzip2
anymore.

Eelco Dolstra 925b975224 Embed the sandbox shell into the statically linked 'nix' binary
With this, Nix will write a copy of the sandbox shell to /bin/sh in
the sandbox rather than bind-mounting it from the host filesystem.
This makes /bin/sh work out of the box with nix-static, i.e. you no
longer get

configure.ac: check for sandbox-shell's FEATURE_SH_STANDALONE
See also: https://bugs.archlinux.org/task/73998. Busybox's
FEATURE_SH_STANDALONE feature causes other busybox applets to
leak into the sandbox, where system() calls will start preferring
them over tools in $PATH. On arch, this even includes `ar`.

Let's check for this evil feature and disallow using this as a
sandbox shell.

Federico Pellegrin e9dbba0fc7 configure: explicit dependency on lowdown library
This dependency is used from quite a long time (now in libcmd) but
was not explicitly stated in the configure phase, possibly leading
to quite late build failures if that was not met (ie. building it
outside the .nix files provided). This MR adds it in the configure
phase so the failure is early and error is much more explicit.

Daniël de Kok 2de232d2b3 Add x86_64 compute levels as additional system types
When performing distributed builds of machine learning packages, it
would be nice if builders without the required SIMD instructions can
be excluded as build nodes.

Since x86_64 has accumulated a large number of different instruction
set extensions, listing all possible extensions would be unwieldy.
AMD, Intel, Red Hat, and SUSE have recently defined four different
microarchitecture levels that are now part of the x86-64 psABI
supplement and will be used in glibc 2.33:

https://gitlab.com/x86-psABIs/x86-64-ABI
https://lwn.net/Articles/844831/

This change uses libcpuid to detect CPU features and then uses them to
add the supported x86_64 levels to the additional system types. For
example on a Ryzen 3700X:

$ ~/aps/bin/nix -vv --version | grep "Additional system"
Additional system types: i686-linux, x86_64-v1-linux, x86_64-v2-linux, x86_64-v3-linux
