Package: dpkg-dev
Version: 1.18.1
Severity: minor
Hello,
I am trying to reproduce a build failure of boost1.54 in a m68k
emulator. While doing that, I noticed that the startup of each
dpkg-buildpackage spends many minutes without any useful task. Looking
at the top output or pstree, I see lots of repeating processes running
dpkg-architecture:
root 1495 0.0 0.2 2272 1612 pts/0 Ss 19:12 0:01 \_ -mksh
root 12001 0.9 1.0 8980 8176 pts/0 S+ 21:36 0:04 | \_
/usr/bin/perl /usr/bin/dpkg-buildpackage -us -uc -b

\_ sh -c LC_ALL=C make -Rrnpsf debian/rules debhelper-fail-me 2>/dev/null
root 12480 0.2 0.1 1832 1308 pts/0 S+ 21:44 0:00 |
\_ make -Rrnpsf debian/rules debhelper-fail-me
root 12511 0.0 0.5 4676 4024 pts/0 R+ 21:45 0:00 |
\_ /usr/bin/perl /usr/bin/dpkg-architecture -qDEB_HOST_ARCH
The -q string keeps chaning all the time but it seems to be still
dpkg-architecture that's called most of the times.
This reminds me on my own packages... after adding
include /usr/share/dpkg/architecture.mk
here and there, it suddenly took 2-3 seconds to start the build without
any visible activity. On the main system, that doesn't bother me much,
but in the slow emulator every wasted minute is bad.
Maybe someone should introduce some workaround to make it run faster,
maybe caching the output somewhere?
Regards,
Eduard.
