Package: sbuild Version: 0.59.0-1 Severity: normal
When using schroot, sbuild runs 'schroot --list' to get a list of all chroots on the machine, and then runs 'schroot --info' separately on each one. While this is fine for machines with a small number of chroots, this results in a startup time that scales quadratically with the number of chroots on the machine (since schroot has to read in every configuration file each time it starts up). In the extreme case, on my machine with hundreds of build chroots, sbuild takes over three minutes to start up: $ time schroot -l | while read c; do schroot --info $c >/dev/null; done real 3m10.275s user 2m45.626s sys 0m21.637s Instead, sbuild should probably run 'schroot --all --list' and extract information about every chroot from the one listing. This operation is fast even with huge numbers of chroots. $ time schroot --all --list > /dev/null real 0m0.128s user 0m0.108s sys 0m0.016s -- System Information: Debian Release: 5.0.3 APT prefers stable APT policy: (600, 'stable'), (300, 'unstable'), (300, 'testing'), (200, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 2.6.26-2-xen-amd64 (SMP w/8 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages sbuild depends on: ii adduser 3.110 add and remove users and groups ii libsbuild-perl 0.59.0-1 Tool for building Debian binary pa ii perl 5.10.0-19lenny2 Larry Wall's Practical Extraction ii perl-modules 5.10.0-19lenny2 Core Perl modules Versions of packages sbuild recommends: ii debootstrap 1.0.10lenny1 Bootstrap a basic Debian system ii fakeroot 1.11 Gives a fake root environment Versions of packages sbuild suggests: pn deborphan <none> (no description available) ii wget 1.11.4-2 retrieves files from the web -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
