make check: grub-mkrescue fails missing unicode.pf2. Leftovers in /tmp

make check: grub-mkrescue fails missing unicode.pf2. Leftovers in /tmp

[Thomas Schmitt]

Hi,

i encountered some stumblestones after running "make check":

-------------------------------------------------------------------------
I see in file ./test-suite.log :

  FAIL: grub_func_test
  ====================

  xorriso 1.5.2 : RockRidge filesystem manipulator, libburnia project.
  ...
  xorriso : FAILURE : Cannot determine attributes of source file '[...]/unicode.pf2' : No such file or directory
  ...
  ./grub-mkrescue: error: `xorriso` invocation failed
  .
  FAIL grub_func_test (exit status: 1)

Instead of "[...]/" before "unicode.pf2" the log shows the absolute path
of the local git repository of GRUB.
I do not see a file unicode.pf2 anywhere in the repo tree after "make".

I ran "make check" as ordinary user. But it would be strange if the
existence of that file depends on superuser powers.

-------------------------------------------------------------------------
The /tmp directory is full of "grub" directories, like:

  drwx------ 2 thomas thomas      4096 Feb 10 09:54 grub-shell.0DW38c5CQP

They are mostly empty, except a few with sub-directory "netdir":

  /tmp/grub-shell.OS3deKSNYs:
  total 4
  drwxr-xr-x 3 thomas thomas 4096 Feb 10 10:25 netdir

and some with more content:

  /tmp/grub-shell.wi7ZdDgpLf:
  total 12
  -rw-r--r-- 1 thomas thomas  347 Feb 10 10:25 grub.cfg
  drwxr-xr-x 2 thomas thomas 4096 Feb 10 10:25 rom_directory
  -rw-r--r-- 1 thomas thomas   20 Feb 10 10:25 testcase.cfg

The timestamps of a group of data files in /tmp suggests that they stem
from the "make check: run, too:

  -rw-r--r-- 1 thomas thomas     17408 Feb 10 10:13 tmp.2XL4eFJ59j


(No .iso files are to see. I looked into /tmp after realizing that those
would not appear in the repo but in /tmp.)

-------------------------------------------------------------------------
And a noob question:

Is there a way to only run the iso9660_test with all surrounding code
of "make check" being in effect ?
(I looked into Makefile but got stuck when looking for the entrails of
target "check-recursive".)


Have a nice day :)

Look at the end of configure message. Is free type enabled? Was unifont
found?

So i would say "freetype2" yes, "unifont" no.

(The system is Debian 11 amd64.)


The test log says:
  FAIL grub_func_test (exit status: 1)
In ./grub_func_test i see

  # Increase memory as some of tests are high-resolution and need a lot of memory.
  out=`echo all_functional_test | ./grub-shell --timeout=3600 --files="/boot/grub/fonts/unicode.pf2"="./"unicode.pf2 --qemu-opts="-m $mem"`

I believe to see the grub-mkrescue invocation in tests/util/grub-shell.in

    exec_show_error "${builddir}/grub-mkrescue" "--output=${isofile}" \
        "--override-directory=${builddir}/grub-core" \
        --rom-directory="${rom_directory}" \
        --locale-directory="${srcdir}/po" \
        --themes-directory="${srcdir}/themes" \
        $mkimage_extra_arg ${mkrescue_args} \
        "/boot/grub/grub.cfg=${cfgfile}" "/boot/grub/testcase.cfg=${source}" \
        ${files} || exit $?

As proof i added a pathspec with an existing filename before ${files}:

-        ${files} || exit $?
+        /x=/home/thomas/x ${files} || exit $?

This file path then appears in the test failure message:

  Added to ISO image: file '/x'='/home/thomas/x'
  xorriso : FAILURE : Cannot determine attributes of source file '/home/thomas/projekte/grub_dir/grub/unicode.pf2' : No such file or directory

So i am sure that the xorriso run in grub-shell.in is the one which fails
and that the bad filename comes from ${files}.
I suspect that ${files} comes from the "--files=" argument that is given
to ./grub-shell by tests/util/grub-shell.in.

Hi,

i have to correct a confused statement of mine:

> I suspect that ${files} comes from the "--files=" argument that is given
> to ./grub-shell by tests/util/grub-shell.in.

The "--files=" argument is given by tests/grub_func_test.in.


Meanwhile i verified that this argument is the origin of the wish for
file unicode.pf2 by changing it from
  --files="/boot/grub/fonts/unicode.pf2"="@builddir@/"unicode.pf2
to
  --files="/x=/home/thomas/x /boot/grub/fonts/unicode.pf2"="@builddir@/"unicode.pf2

This yields again the name of my existing /home/thomas/x before the
xorriso error message about unicode.pf2:

  Added to ISO image: file '/x'='/home/thomas/x'
  xorriso : FAILURE : Cannot determine attributes of source file '/home/thomas/projekte/grub_dir/grub/unicode.pf2' : No such file or directory


Have a nice day :)

You have the package xfonts-unifont installed correct? You also don't
have the djvu fonts, but I don't think that's affecting this issue.

If you do have the unifonts installed, you may need to run configure
with shell tracing on to see whats really going on. You can do this
like:

  sh -x ./configure

If you don't see where the issue is, xz the output and send it here.

This is the recommended OS for running the test suite.

IIRC, grub-mkfont creates unicode.pf2 and puts it in the root of the
build directory. Since grub-mkfont is not being built, this generated
file will not be created.

Urm, no. (I have no desktop running. Just fvwm.)
Is the need for this package documented somewhere ?

Well, now it is installed. I do

  $ ./configure
  ...
  GRUB2 will be compiled with following components:
  ...
  With unifont from /usr/share/fonts/X11/misc/unifont.pcf.gz
  ...
  $ make

  $ make check

The complaints about the xorriso run do not appear any more.


Now grub_func_test fails with other log messages:

Those messages are outside my range of knowledge.
If i shall try to tackle them, i'd need exact instructions.

IIRC, xfonts-unifont is pulled in by the unifont package on Debian, but
it is the one with the files you need. No, its not documented, but then
not every single debian package name needed is documented because the
documentation is partially distribution agnostic. If it were documented
it would be in ./INSTALL, which does talk about needing unifonts. If
you'd like to modify that file to help other Debian users, I'm
supportive.

These are very old, well known, and expected failures. I would love for
someone to fix them, but there's little interest. Daniel Axten looked
into fixing them a couple years ago, but looks like a pain[1]. I think
we should either only checksum the part of the image that doesn't
contain the version number, or generate the checksums in
grub-core/tests/checksums.h at build time.

Unicode is mentioned two times in INSTALL.
Once for building "GRUB's graphical terminal (gfxterm)", once as
"Platform-agnostic tools and data".

There is also a section "Debian named packages required mostly for the
full suite of filesystem testing" which could host the name of the needed
package. Although it is not about filesystems the mentioning could be
justified by the word "mostly" in the headline.
Or it could be mentioned as own point one level higher under
"Prerequisites for make-check".


But actually the lack of unifont did not hamper building GRUB from git.
So i would expect that this tolerance is somewhat reflected by the tests.

How about putting in tests/grub_func_test.in a test for the existence of
/boot/grub/fonts/unicode.pf2 with an informative error message if it is
missing ?
Since we know that xorriso under grub-mkrescue will cause early failure if
the file is missing, there is no use in running grub-shell with the demand
for unicode.pf2.

I see that grub_func_test.in already has provisions to declare
"Functional test failure". Maybe the new code path could join that.
Or it could be declared as skipped. (I still have to find out how to
cause a SKIP message in the test log.)


Have a nice day :)

I meant "Unifont" and "unifont".

Yes, I like this. And in your case you got a test failure, when you
should get a test error, which indicates that the test could not
actually be run and so was not a true failure.

A SKIP is caused by exiting with code 77. However, that's not what
should be done in this case.

I'll send a patch for this soon based on these suggestions.

Yes, I think these are made by some of the test scripts. I think these
should be better named (like "grub-tmp.TEST_NAME.XXXXXXX").

You can change the tmp used via the TMPDIR envvar. It would be nice for
the grub-shell script to cleanup these empty grub-shell.*
temporary directories. Although there are reasons not to cleanup them
up, like for debug purposes or not test error.

Yes, I think these are made by some of the test scripts. I think these
should be better named (like "grub-tmp.TEST_NAME.XXXXXXX").

You can change the tmp used via the TMPDIR envvar. It would be nice for
the grub-shell script to cleanup these empty grub-shell.*
temporary directories. Although there are reasons not to cleanup them

Yes there is[1]. You can run them like: 

  make TESTS=iso9660_test SUBDIRS= check
