Package: debhelper
Version: 9.20150101
Severity: normal
I'm building packages using cowbuilder/pbuilder. Recently I also do this for
armhf using qemu. There it happens, that I run into problems with dh_fixperms
and dh_md5sums for packages with lots of files.
e.g. one package contains about 1459 files, wich makes an argument list of
about 140kB. `xargs --show-limits` reports:
Your environment variables take up 6150 bytes
POSIX upper limit on argument length (this system): 2088954
POSIX smallest allowable upper limit on argument length (all systems): 4096
Maximum length of command we could actually use: 2082804
Size of command buffer we are actually using: 131072
....and dh_md5sums causes a "/usr/bin/xargs: md5sum: Argument list too long"
To be honest, I couldn't figure out, why this only happens for my armhf builds
and not for i386 and amd64. `xargs --show-limits` reports always the same
values.
But I think at least the xarg-calls for md5sum and chown should be replaced
with something safer like "xargs -r0 -L10 md5sum" to avoid trouble with
packages containing a lot of files.
