Personal PKGBUILD for Emacs giving error when running tests

I am trying to write my own PKGBUILD file for Emacs (with my own custom configuration), but I keep encountering a problem when `makepkg` runs the `check ()` function, which I have set as:

    check (){
            cd ${pkgname}-${pkgver}
            make -k check
    }

This is run after `build`, and results in one of the tests failing:

    FAILED  1/7  emacs-tests/bwrap/allows-stdout (1.676436 sec) at src/emacs-tests.el:175
    passed  2/7  emacs-tests/seccomp/absent-file (0.215495 sec)
    passed  3/7  emacs-tests/seccomp/allows-stdout (0.365716 sec)
    passed  4/7  emacs-tests/seccomp/empty-file (0.213629 sec)
    passed  5/7  emacs-tests/seccomp/file-too-large (0.435880 sec)
    passed  6/7  emacs-tests/seccomp/forbids-subprocess (1.323565 sec)
    passed  7/7  emacs-tests/seccomp/invalid-file-size (0.306250 sec)

    Ran 7 tests, 6 results as expected, 1 unexpected

    1 unexpected results:
    FAILED  emacs-tests/bwrap/allows-stdout

But if I build Emacs with my config flags by just running `./configure $confflags` (assume `$confflags` has my full list of options), running `make` and then doing `make -k check`, there is no problem with the test -- it passes:

    passed  1/7  emacs-tests/bwrap/allows-stdout (0.290183 sec)
    passed  2/7  emacs-tests/seccomp/absent-file (0.042133 sec)
    passed  3/7  emacs-tests/seccomp/allows-stdout (0.070669 sec)
    passed  4/7  emacs-tests/seccomp/empty-file (0.035593 sec)
    passed  5/7  emacs-tests/seccomp/file-too-large (0.053210 sec)
    passed  6/7  emacs-tests/seccomp/forbids-subprocess (0.362152 sec)
    passed  7/7  emacs-tests/seccomp/invalid-file-size (0.036310 sec)

    Ran 7 tests, 7 results as expected, 0 unexpected

This is my first time writing a proper `PKGBUILD` file so I'm probably doing something incorrect.
But is there some kind of permissions issue -- i.e. does `makepkg` need me to run `sudo make -k check` -- that has to be addressed before I can run the check?


FYI: The test in question is not particular relevant to me, but I'd like to understand why it is not passing. I understand that it involves using the audit framework but this is not something that I've enabled as a kernel parameter, and enabling/disabling `auditd.service` does not fix this.

Same as
https://forum.manjaro.org/t/building-em … ck/170360/
https://www.reddit.com/r/emacs/comments … or_failed/ ?

I don't think this has anything to o w/ the audit system - it's more likely that bwrap fails in the fakeroot environment.

Re: Personal PKGBUILD for Emacs giving error when running tests

Thanks -- is there something I can do to check or test this? I didn't see the message about entering fakeroot when running `makepkg` (which I sometimes see when AUR packages are built).

Re: Personal PKGBUILD for Emacs giving error when running tests

"fakeroot make -k checkI",  guess - but from the manpage check() isn't actually run under fakeroot…

Stupid question, what if you run make check in the build() function?

Re: Personal PKGBUILD for Emacs giving error when running tests

Huh ... running

fakeroot make -k check

in the existing `src/emacs-29.4` directory created by `makepkg` doesn't produce the `allow-stdout`/`bwrap` error above -- that test passes -- but now there is a different error from `bytecomp-tests.el`:

Ran 84 tests, 83 results as expected, 1 unexpected

1 unexpected results:
   FAILED  bytecomp-tests--dest-mountpoint

Stupid question, what if you run make check in the build() function?

Following your question, I added `make -k check` to the `build()` function and removed `check()` from the `PKGBUILD`. This still produces the same `bwrap` related test error from before.

Re: Personal PKGBUILD for Emacs giving error when running tests

In case the seccomp test for stdout gets skipped (absent seccomp) it might be really that.

make -k check  >&-

then probably fails? Do you still get output (on stderr)?

Re: Personal PKGBUILD for Emacs giving error when running tests

Sorry, not sure I understand. Are you saying that I should have

make -k check  >&-

in the `check()` function?

Also, I have been running all these commands with a `

|& tee foo.log

so that I can keep track of all the output after making changes, including from `stderr`.

Re: Personal PKGBUILD for Emacs giving error when running tests

The idea is that "make -k check  >&-" will fail outside the pkgbuild because you're closing the stdin.

Re: Personal PKGBUILD for Emacs giving error when running tests

I still wasn't sure what you meant for me to try, so here is what happens when I run `make -k check >&-` by hand:

  INFO     Scraping files for loaddefs...
  INFO     Scraping files for loaddefs...done
  INFO     Scraping files for loaddefs...
  INFO     Scraping files for loaddefs...done

SUMMARY OF TEST RESULTS
-----------------------
Files examined: 471
Ran 7038 tests, 6877 results as expected, 0 unexpected, 161 skipped

This is the same result as before -- no errors in the tests -- but now the output has been suppressed.


I also run `makepkg` with the `check` function defined as

check (){
	cd ${pkgname}-${pkgver}
	make -k check >&-
}

There is now less output when the `check` part of PKGBUILD is run, but I still get the original error, plus a new one that might be related to the suppression of `stdin`:

make[3]: *** [Makefile:293: src/emacs-module-resources/mod-test.so] Error 1
make[3]: Target 'src/emacs-module-tests.log' not remade because of errors.

This - and apparently it's not a closed stdout that's at fault (but breaks a different test)

You'll have to debug emacs-tests.el, ie. make it print more about what it does and what fails how.
Or do you get an error log for the original problem, too?

At this point, it might be worth just raising this as a bug on the Emacs mailing list.

Re: Personal PKGBUILD for Emacs giving error when running tests

Does 

export MAKEFLAGS="--jobs=$(nproc)"

or 

export MAKEFLAGS="--jobs=2"

  help with that?

Thanks, but no change in the error unfortunately.
