find sizes of installed packages

September 9th, 2006

Sometimes, especially when disk space is low (or when system backups grow unreasonably large), it's nice to know exactly how much space the biggest packages occupy. Obviously, OpenOffice is never above suspicion, but certain others can take up way more space than you would think.

I wrote a little script to print the size of all packages installed on the system. It uses the CONTENTS file for every installed ebuild to check the size of the files which belong to a package and give a sorted listing of packages by size.

pkgdb = "/var/db/pkg"


import os, string, stat
from operator import itemgetter

sizes = {}

cats = os.listdir(pkgdb)
for c in cats:
	cpath = os.path.join(pkgdb, c)
	if os.path.isdir(cpath):
		cat = os.listdir(cpath)
		for p in cat:
			size = 0
			
			cont = os.path.join(pkgdb, c, p, "CONTENTS")
			fd = open(cont, 'r')
			
			strings = fd.readlines()
			for s in strings:
				line = string.split(s, " ")
				if line[0] == "obj" and os.path.exists(line[1]):
					size += os.path.getsize(line[1])
			
			fd.close()
			
			sizes[os.path.join(c, p)] = size

pkglist = sorted(sizes.items(), key=itemgetter(1))

for i in pkglist:
	(size, pkg) = ( str(i[1]), i[0] )
	print string.rjust(size, 11), " ", pkg

The output looks like this:

          0   virtual/x11-7.0-r2
         66   kde-base/kde-env-3-r4
        393   kde-base/kdebase-pam-6
        889   sys-apps/coldplug-20040920-r1
...
      94217   net-ftp/ftp-0.17-r6
      94642   kde-base/kcminit-3.5.3
      95629   sys-process/psmisc-22.2
      95931   sys-apps/ivman-0.6.12
      97358   app-admin/gnomesu-0.3.1
...
  122593614   dev-java/sun-jdk-1.5.0.08
  132864794   dev-lang/ghc-6.4.2
  145477793   app-text/tetex-2.0.2-r8
  221943002   sys-kernel/gentoo-sources-2.6.17-r7
  340336824   app-office/openoffice-bin-2.0.3

Unsurprisingly, OpenOffice claims victory, but this is a small reminder about how big kernel sources are. Tetex and GHC aren't minimalistic either.

UPDATE: Paludis bug fixed.

    I have a bug (?!). paludis makes a symlink in /var/db/pkg (like this: world -> /var/lib/portage/world) and pkgsize.py fails with:
    File "./pkgsize.py", line 16, in ?
    cat = os.listdir(os.path.join(pkgdb, c))
    OSError: [Errno 20] Not a directory: '/var/db/pkg/world'

    That was unexpected, but I fixed the bug now.
