Package: emdebian-tools Version: 1.4.6 Severity: important During Extremadura, Wookey discovered a nasty bug in emdebian-tools whereby the chroot code would fail if /bin/sh was not a symlink to /bin/bash.
With the upcoming release of Lenny where this is now explicitly supported, this was a problem. I couldn't see my way through this problem whilst at Extremadura (possibly something to do with too much beer, too little air-conditioning and too many other problems to fix) but I think I have a solution now. The problem only arises because debootstrap calls exec within itself - mainly to redirect STDOUT and STDERR. debootstrap itself is POSIX shell so it is set to #!/bin/sh which is fine. However, during processing, debootstrap calls first_stage_install which is a function defined in the suite scripts. These suite scripts are sourced by debootstrap, not executed, so any shebang line is ignored. This means that if first_stage_install calls any bash code, debootstrap fails when /bin/sh is not linked to /bin/bash. Initially, I added a manpage warning and thought we might have to live with this bug for a while. The bash code involved comes not just from emdebian-tools but from pbuilder so it is unreasonable to expect pbuilder to change just because emdebian-tools happens to try and bring the two sets of libraries into play at the same time. The pbuilder code itself is the mountproc and related code - I'd rather not have to fork it with a non-bash version. However, I think there is a solution for this problem - the pbuilder code required for building a cross-building chroot is not needed when building a root filesystem chroot. empdebuild calls pbuilder functions only after second_stage_install and when using the built chroot for building packages etc. (when debootstrap has finished). By splitting empbuilderlib into two libraries, one bash and one POSIX, I can avoid trying to call pbuilder functions within first_stage_install when generated the root filesystem chroot as well. Moving all the first_stage_install routines into a new library, emrootfslib, and making that library POSIX only will allow the necessary isolation of the pbuilder code from first_stage_install. I'm taking the opportunity to also reorganise the directories - POSIX code will live in /usr/share/ and code that absolutely must rely on pbuilder code lives alongside pbuilder code in /usr/lib/. (If pbuilder eventually moves to /usr/share/pbuilder/, the pbuilder code will move to /usr/share/emdebian-tools/.) This problem exists in the version of emdebian-tools in Lenny and Sid - a fixed package will probably be backported along with other important changes, after Lenny is released. -- Package-specific info: -- System Information: Debian Release: lenny/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.26-1-amd64 (SMP w/2 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages emdebian-tools depends on: ii automake 1:1.10.1-3 A tool for generating GNU Standard ii automake1.9 1.9.6+nogfdl-3 A tool for generating GNU Standard ii cdbs 0.4.52 common build system for Debian pac ii dbs 0.45 Allows Debian source packages with ii debhelper 7.0.17 helper programs for debian/rules ii dpatch 2.0.30 patch maintenance system for Debia ii dpkg-dev 1.14.22 Debian package development tools ii emdebian-qa 1.4.6 emdebian quality assurance support ii emdebian-rootfs 1.4.6 emdebian root filesystem support ii fakeroot 1.9.6 Gives a fake root environment ii g++ 4:4.3.1-2 The GNU C++ compiler ii gcc 4:4.3.1-2 The GNU C compiler ii gettext 0.17-4 GNU Internationalization utilities ii libcache-apt-perl 0.12.3 object oriented apt cache perl bin ii libdebian-dpkgcross-perl 2.3.1 functions to aid cross-compiling D ii libemdebian-tools-perl 1.4.6 emdebian support library ii libsoap-lite-perl 0.710.08-1 Client and server side SOAP implem ii lsb-release 3.2-20 Linux Standard Base version report ii perl 5.10.0-13 Larry Wall's Practical Extraction ii quilt 0.46-6 Tool to work with series of patche ii subversion 1.5.1dfsg1-1 Advanced version control system ii sudo 1.6.9p17-1 Provide limited super user privile ii ucf 3.0010 Update Configuration File: preserv Versions of packages emdebian-tools recommends: ii less 418-1 Pager program similar to more Versions of packages emdebian-tools suggests: ii deb-gview 0.2.2 GNOME viewer for .deb package file ii debian-xcontrol 0.0.2~pre1+nmu2 Extended syntax for debian/control ii file-roller 2.22.4-2 an archive manager for GNOME ii meld 1.1.5.1-2 graphical tool to diff and merge f ii mutt 1.5.18-4 text-based mailreader supporting M ii reportbug 3.45 reports bugs in the Debian distrib ii wiggle 0.6-6 a program for applying patches wit -- debconf information: * emsource/svnusername: codehelp * emsetup/aptagent: true * emsource/targetsuite: unstable * emsource/workdir: /opt/emdebian/ emsetup/primary: -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
