Bug#526471: pbuilder: pdebuild-internal fails to execute hook scripts

[Francesco Poli (t1000)]

Package: pbuilder
Version: 0.187
Severity: normal

Hi and thanks for maintaining pbuilder!

I have a problem with pdebuild in the use-pdebuild-internal mode of
operation.

With the following configuration file:

  $ cat ~/.pbuilder/sid.conf
  DISTRIBUTION="sid"
  COMPONENTS="main"
  MIRRORSITE="http://ftp.it.debian.org/debian"
  APTCACHE="${HOME}/var/cache/pbuilder/aptcache/${DISTRIBUTION}/"
  APTCACHEHARDLINK="no"
  BASETGZ="${HOME}/var/cache/pbuilder/${DISTRIBUTION}-base.tgz"
  BUILDPLACE="${HOME}/var/cache/pbuilder/build/"
  BUILDRESULT="${HOME}/var/cache/pbuilder/result/${DISTRIBUTION}/"
  HOOKDIR=""
  DEBBUILDOPTS="-i -I"
  BINDMOUNTS=""
  USE_PDEBUILD_INTERNAL="yes"
  DEBOOTSTRAPOPTS[0]="--variant=buildd"
  DEBOOTSTRAP="cdebootstrap"
  EXTRAPACKAGES="gnupg debian-archive-keyring"
  USEPROC="yes"
  USEDEVPTS="yes"
  USEDEVFS="no"
  REMOVEPACKAGES="lilo elilo grub grub2"
  BUILDSOURCEROOTCMD="fakeroot"
  PBUILDERROOTCMD="sudo"
  BUILDUSERID="9999"
  BUILDUSERNAME="pbuilder"
  export DEBIAN_FRONTEND="noninteractive"
  AUTO_DEBSIGN="yes"
  PKGNAME_LOGFILE="yes"
  PKGNAME_LOGFILE_EXTENTION=".buildlog"
  export debian_chroot="pbuild$$"

and with some hook scripts, such as:

  $ cat ~/.pbuilder/pdeb-hooks-sid/B95shell_pdeb 
  #!/bin/bash
  
  # invoke shell (from a pdebuild environment)
  apt-get install -y --force-yes vim less
  cd ${HOME}
  /bin/bash < /dev/tty > /dev/tty 2> /dev/tty

which do have execution permissions:

  $ if test -x ~/.pbuilder/pdeb-hooks-sid/B95shell_pdeb 
    then
        echo "yes, the hook script is executable..."
    fi
  yes, the hook script is executable...

I fail to get a shell, when building a package:

  $ pdebuild --configfile ~/.pbuilder/sid.conf --debbuildopts "-i -I" \
    -- --hookdir ~/.pbuilder/pdeb-hooks-sid

The package is correctly built and signed, but no hook script seems
to be executed.


Now the good news: I think I found out what's wrong, and I am right now
working on a patch.
Please stay tuned...  ;-)
