Dear Maintainer,

I'm trying to follow dgit-user(7) to build a modified version of a package.
I did:

$ dgit clone valgrind
$ cd valgrind
$ git apply ../my_special_patch.diff
$ git commit -m "Way better than vanilla!"
$ gbp dch -S --since=dgit/dgit/sid --ignore-branch --commit
$ git clean -xdf
$ sbuild -c buster-amd64 -A --no-clean-source --dpkg-source-opts='-Zgzip -z1 --format=1.0 -sn'

But this eventually fails with:


dpkg-buildpackage
-----------------

Command: dpkg-buildpackage -us -uc -rfakeroot

Hi.  This is a thing you should be able to do.
...

How sad.

There are two things wrong here.

One is that sbuild seems to be ignoring the --dpkg-source-opts, or
maybe the rune was always wrong.  I think I will have to investigate.
I *thought* we had a test for this rune but maybe not one involving
sbuild.

... yes, we do.  tests/tests/sbuild-gitish.  Obviously the test isn't
working right.

The other oddity, is that this complaint about
valgrind_3.15.0.orig.tar.* implies that there isn't a
valgrind_3.15.0.orig.tar.bz2 but when I tried dgit clone valgrind it
left me one in my "..".  I conjecture that you have a non-default
build-products dir for dgit but your sbuild doesn't have that
configured ?  This ought not to matter with the --format=1.0 -sn rune.
I don't think this is in your way but it would be nice to confirm that
there isn't another bug here.


Regards,
Ian.

Hi Ian,

Thanks for the quick response!

Yes, I have one too:

$ ls -d ../valgrind*
../valgrind/
../valgrind_3.15.0.orig.tar.bz2
../valgrind_3.15.0-1.debian.tar.xz
../valgrind_3.15.0-1.dsc
../valgrind_3.15.0-1.tar.gz
../valgrind_3.15.0-1_amd64.build@
../valgrind_3.15.0-1_amd64-2020-04-27T18:01:38Z.build
../valgrind_3.15.0-1_amd64-2020-04-27T18:05:35Z.build

../valgrind_3.15.0-2~1.gbpd4e99a_amd64-2020-04-27T18:06:33Z.build

I don't remember setting something like this, but I may have
forgotten. Where would I look for that?

I do not have a ~/.dgit*, nor is dgit mentioned in ~/.gitconfig.

Best,
-Nikolaus

I have been trying to repro this.  My main dev environment is running
stretch.  I ran

   dgit clone valgrind
   cd valgrind/
   sbuild -c build -A --no-clean-source --dpkg-source-opts='-Zgzip -z1 --format=1.0 -sn'

and it got as far as compiling a lot of C files.  The build failed
like this:

   In file included from libmpiwrap.c:116:
   libmpiwrap.c: In function 'showTy':
   /usr/lib/x86_64-linux-gnu/openmpi/include/mpi.h:322:57: error: expected expression before '_Static_assert'

I conjecture that this was the thing you were trying to fix...

I will try a repro from my sid chroot, but of course running sbuild
*inside* the chroot is going to be a bit complicated...

OK.  Good.

Ian.

Hi Ian,

FWIW, I have tried this on an AMD64 buster system with an AMD64 chroot. When compiling without schroot it works fine (I was trying to add support for the copy file range syscall, not fix a compile error)

(Sorry for the bad quote, replying from my phone since I won't be at a proper computer until tonight.)

Best,
Nikolaus

Nikolaus Rath writes ("Bug#958989: dgit-user(7): building instructions don't work"):

OK.  That's strange.  How recently was your chroot updated ?

For you, does it fall over from the dpkg-source error before or after
the actual build ?  Can you send me the whole build log please ?

No problem, thanks.

Ian.

Nikolaus Rath writes ("Re: Bug#958989: dgit-user(7): building instructions don't work"):

The FTBFS is real and already reported, it seems.

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=946329

I will try with those patches...

Ian.

I was good until here.

I replaced this with "apt build-dep valgrind"

This failed, because there is no such directory. I think you're assuming
that my current directory is bind-mounted into the chroot. I'm not sure
if this is supposed to happen, but previous sbuild incarnations from within
the same directory have worked with this configuration.

My schroot configuration is:

[buster-amd64]
description=Debian buster/amd64 autobuilder
type=btrfs-snapshot
btrfs-source-subvolume=/srv/chroot/buster-amd64
btrfs-snapshot-directory=/srv/chroot
groups=root,sbuild
root-groups=root,sbuild
source-groups=root,sbuild
profile=sbuild
command-prefix=eatmydata

/etc/schroot/sbuild/fstab says:

# fstab: static file system information for chroots.
# Note that the mount point will be prefixed by the chroot path
# (CHROOT_PATH)
#
# <file system>	<mount point>	<type>	<options>	<dump>	<pass>
/proc		/proc		none    rw,bind        0       0

/dev            /dev            none    rw,bind         0       0
/dev/pts	/dev/pts	none	rw,bind		0	0
tmpfs		/dev/shm	tmpfs	defaults	0	0
#/home           /home_host      none    rw,rbind     0   0
# Mount a large scratch space for the build, so we don't use up
# space on an LVM snapshot of the chroot itself.
#/var/lib/sbuild/build	/build	none	rw,bind	0	0
/var/cache/apt/archives /var/cache/apt/archives none rw,bind 0 0


For now, I have manually bind-mounted the directory into the chroot.

This worked.

Uhm. I feel pretty dumb, but what is the "958989" supposed to do?

$ sbuild -c buster-amd64 -b -n 958989
No distribution defined

Without that, I get:

I updated the chroot about an hour before I filed the bug.

The error occurrs before compilation started.

Will send you a full log tonight.

Best,
Nikolaus

Nikolaus Rath writes ("Re: Bug#958989: dgit-user(7): building instructions don't work"):

This is supposed to create a chroot session called "958989" made out
of a snapshot of your "buster-amd64".  But I wrote "sbuild" rather
than "schroot" !

Err, yes.

Sorry!

Ina

Nikolaus Rath writes ("Re: Bug#958989: dgit-user(7): building instructions don't work"):

This is getting quite odd.

In that case it is working for me.

Thanks.

Could I get you to do this:

 sbuild -c buster-amd64 -b -n 958989

 schroot -rc 958989 -u root
   apt install sbuild autopkgtest dgit
   apt install build-dep valgrind
   cd ..../valgrind
   mkdir ../aside
   mv ../valgrind_* ../aside
   sbuild --chroot-mode=autopkgtest --autopkgtest-virt-server=null -A \
     --no-clean-source --dpkg-source-opts='-Zgzip -z1 --format=1.0 -sn'

and send me the log ?

Thanks,
Ian.

Ian Jackson writes ("Re: Bug#958989: dgit-user(7): building instructions don't work"):

They don't seem to have fixed the FTBFS for me.

I ran this:

 sbuild --chroot-mode=autopkgtest --autopkgtest-virt-server=null -A \
 --no-clean-source --dpkg-source-opts='-Zgzip -z1 --format=1.0 -sn'

inside my sid chroot.

Nikolaus Rath writes ("Bug#958989: dgit-user(7): building instructions don't work"):

This is all quite mysterious to me and I'm not sure where to go next.

There are *two* things I don't understand:
(1) Why your sbuild with schroot rune fails but mine succeeds
(2) Why I get an FTBFS on the original valgrind from sid, when
   apparently you don't

Since you say the failure (1) occurs before the build starts, I think
these two things are unrelated, and it will hopefully be possible to
debug (1) without having to understand (2).  I'm hoping that (2) will
be fixed by an upload of valgrind to sid which fixes #946329 ...


So on with (1).  To recap, AIUI we now have a situation where in your
setup

(a)   sbuild -c buster-amd64 -A \
          --no-clean-source --dpkg-source-opts='-Zgzip -z1 --format=1.0 -sn'

gives the error from dpkg-source, but

(b)   schroot into the buster-amd64 chroot
      sbuild --chroot-mode=autopkgtest --autopkgtest-virt-server=null -A \
          --no-clean-source --dpkg-source-opts='-Zgzip -z1 --format=1.0 -sn'

works.

I think (a) will run dpkg-source to build the source pacakge outside
the chroot.  (b) obviously runs it inside it.  Maybe you have some
environment variable or a funny version of dpkg-dev or something ?

Can you send me the output of
   printenv | sort
and the version of dpkg-dev you have outside the chroot ?


Also I would like to try a repro that is smaller than valgrind :-).
I wonder if you would be willing to try using the test case from the
dgit test suite:

  # apt --no-install-recommends install dgit dgit-infrastructure
    devscripts debhelper fakeroot build-essential chiark-utils-bin \
    bc faketime liburi-perl sbuild man-db
  # ^ # from dgit/debian/tests/control, stanza for sbuild-gitish

  $ dgit clone dgit
  $ cd dgit
  $ DGIT_SCHROOT_CHROOT=buster-amd64 tests/tests/sbuild-gitish 2>&1 |tee log


Thanks for your help debugging this...

Ian.

Here's another datapoint:

$ dgit clone valgrind
$ cd vagrind; sbuild -c buster-amd64

works fine (i.e., if I don't apply any changes).

Yes - with the caveat that in the second case I manually bind-mounted
the directory that contained the .orig.gz and the git repo.

Hi.  I was looking at this again, perhaps with a clearer head than
before.

You wrote:

I don't think we should be trying to rebuild the source package at
this point.  Empirically, when invoked in a directory, sbuild runs
dpkg-source directly to build the source package, even before it
prints its banner line.  The source package ought not then to be
*re*built via dpkg-buildpackage.

The rune in dgit-user(7) is intended to cause the source package built
by sbuild's invocation of dpkg-source to be built as 1.0, to bypass
all of the things that can go wrong with `3.0 (quilt)`.  But the
example rune doesn't also have sbuild pass those options through
dpkg-buildpackage to the 2nd invocation of dpkg-source, becauwe it's
not expecting there to *be* a 2nd invocation.

In my test suite, where I test the rune out of the manpage, I see this
in the corresponding part of the sbuild logfile:

| dpkg-buildpackage

| Command: dpkg-buildpackage -us -uc -b -rfakeroot
| dpkg-buildpackage: info: source package example

| dh_clean: warning: Compatibility levels before 10 are deprecated (level 8 in use)
|  debian/rules build

Note the ddifference in dpkg-buildpacakge invocations:
| Command: dpkg-buildpackage -us -uc -b -rfakeroot

I don't seem to be able to find in this bug a complete sbuild logfile
from a repro of the original report, but:

RTFMing sbuild suggests that the "--source" option may be implicated -
especially, via the BUILD_SOURCE sbuild config variable.

Do you have this setting in your personal configuration ?

Thanks,
Ian.
