Subject: 28.0.50; comp-tests suite creates a /nonexistent directory
Date: Sun, 14 Mar 2021 17:59:14 +0200

Running test/src/comp-tests.el causes creation of the directory
/nonexistent/.emacs.d/eln-cache/ and puts there *.eln files it
generates.  I think the test (or test/Makefile) should be modified to
direct the eln cache to some temporary directory that should be
deleted after the test completes.  Otherwise the files in this eln
cache could affect future test runs.

Hi Eli,

just a question: how are you invoking the tests in comp-tests.el?

Thanks

Like this:

  $ cd test
  $ make src/comp-tests SELECTOR='(not comp-tests-bootstrap)'

Is /nonexistent... really created in the root?  AFAICS on my system the
usual 'native-lisp' directory is used for these compilations.  Might be
this Windows specific?

Yes.  (Well, no, because MinGW maps "/" to some place else, but that's
an internal detail of how MinGW and MSYS work with Posix file names.)

> AFAICS on my system the usual 'native-lisp' directory is used for

Really? that's peculiar, because test/Makefile says:

  # Set HOME to a nonexistent directory to prevent tests from accessing
  # it accidentally (e.g., popping up a gnupg dialog if ~/.authinfo.gpg
  # exists, or writing to ~/.bzr.log when running bzr commands).
  TEST_HOME = /nonexistent
  ...
  %.log: %.elc
	$(AM_V_at)${MKDIR_P} $(dir $@)
	$(AM_V_GEN)HOME=$(TEST_HOME) $(emacs) \
	  -l ert ${ert_opts} -l $(testloadfile) \
	  $(TEST_RUN_ERT)

Does Emacs on GNU/Linux ignore a nonexistent home directory, and uses
the original one instead?  That'd mean the above trick isn't working.

> Might be this Windows specific?

I hope not.

I see, the target directory for a newly compiled .eln is the first entry
in `comp-eln-load-path', so HOME is not accounted and the trick didn't
applied.

Okay af739863b0 when running the testsuite is adding in front of
`comp-eln-load-path' a temporary directory such that now all native
compilations tests are deposed and loaded there.  Does is look like a
good solution?

Thanks

Right, makes sense.

Yes, I think so.  But please add a note in test/Makefile.in, where
this /nonexistent trick is set up, that if the name is changed,
startup.el should be changed as well.

However, I've run the test suite after updating from Git, and that
/nonexistent directory is still being created, with files
comp-test-funcs, comp-test-funcs-dyn, comp-test-45603, and a few
subr--trampoline* files.  The rest of the *.eln files created by the
test are going to the temporary directory, but there's no
emacs-testsuite-NNN subdirectory there.  Any ideas what could be
causing that?

Thanks.

Hard-coding a check in startup.el based on a setting for HOME that
happens to be used by the test-suite doesn't look like a good solution
to me. I'm not familiar with the native compilation branch, so I won't
try to suggest an alternative. Also, the Emacs tests generally try to
clean up when they exit, and it looks like nothing ever deletes this
temporary directory?

Hi Glenn,

if we have a better idea on how to detect we are running the testsuite
we can use that in place.  Maybe defining a dedicated env variable
during the build?

Thanks

Right, ec12cdd197 does that, in case we'll find a more elegant way for
the future I'll clean this up.

Mmhh no, not really.  These native compilations are triggered from the
"comp-tests.el" top-level but they should still obey to
`comp-eln-load-path' that we set earlier.

On my system these are create in the temporary dir, I'll think about but
we may need to debug this it sounds strange.

Howe about EMACS_ELN_PATH, similar to EMACS_LOADPATH?  Then the test
Makefile could set it for the src/comp-tests test.

That's an idea but how can we create a temporary directory to set into
EMACS_ELN_PATH from the build system?

I was thinking more to an env far to check for to replace the

(equal (getenv "HOME") "/nonexistent")

we have in `normal-top-level' with:

(getenv "TESTSUITE_RUN")

Thanks

It looks like this now works OK in Emacs 29 (except for the number of
temp files that's dumped in /tmp, but I've opened a new bug report for
that).

Eli, does this work for you too (on the trunk)?

The /nonexistent directory is no longer created.  But there are a lot
of freefn-XXXXX.eln directories in /tmp.

Yes, and I've opened a new bug report for that.  So I'm closing this bug
report, then.
