pacfix

Pierluigi · 2007-02-06 19:40:04

A script to list all the packages currently installed, according to /var/log/pacman.log

it can help in case of a broken/lost pacman database (/var/lib/pacman)

Remember that packages installed during arch setup are not logged in /var/log/pacman.log, so they are found by this script only if they were upgraded later.

#!/usr/bin/env python
#
# pacfix.py: a script by pierluigi to list all the packages currently installed according to /var/log/pacman.log


pkg=[]

logfile = open("/var/log/pacman.log","r")
log=logfile.readlines()
for myline in log:
    myarray = myline.strip("\n").split(" ")
    if (myarray[2]=="installed" or myarray[2]=="upgraded"):
        if (pkg.count(myarray[3])==0):
            pkg.append(myarray[3])
    if (myarray[2]=="removed"):
        if (pkg.count(myarray[3])!=0):
            pkg.remove(myarray[3])
pkg.sort()
for p in pkg:
    print p

Available also in "pactools" @ AUR

It doesn't work for me:

$ pacfix.py | wc -l
665

$ pacman -Q | wc -l
530

pacfix shows some removed packages

well that's a bit strange. this script has been tested on my system and by a couple of italian users.

i will investigate what it can be...

noriko · 2007-02-06 21:02:27

umm, this isn't reliable ... why not use /var/lib/pacman/local ?

i wrote this script some time ago .. it's on this forum somewhere with other scripts that do more or less same thing...

#!/usr/bin/python

import os


pd = '/var/lib/pacman/'
total = 0

def okd(prfx,dr):
    if os.path.isdir(prfx+dr) and dr[0] != '.' and dr != 'local':
        return True
    else:
        return False    

sep = '--------------------------------------'

print 'Misc. Stats on Packages in Pacman DBs.\n'+sep


for db in os.listdir(pd):
    if okd(pd,db):
        count = 0
        for pk in os.listdir(pd+db):
            if okd(pd+db+'/',pk):count += 1
        print 'Packages in ['+db+'] Repo. :'+str(count)
        total += count
        
installed = 0
for ix in os.listdir(pd+'/local'):
            if okd(pd+'/local/',ix):installed += 1
            
print sep+'\nThere are '+str(total)+' Packages in Total,\n\
of which '+str(installed)+' are Installed.\n'+sep

because i wrote it to help an user who accidentally removed his pacman database (/var/lib/pacman/local).

I know that should be better backing up the DB, but this script may help when no backup is available and you want to know which packages have been installed.

Nice script, for me it was very accurate, here's a diff below

$ comm -3 <(pacman -Q|cut -d' ' -f1) <(python pacfix.py)
    beryl-plugins
    control-center
    inside
unifdef

I checked the pacman.log file, and well its not the scripts fault, pacman just didn't log the removal of some of those files *shrug*.
Anyways, one of them was a mistake 'inside', here's the line where it got it from.

[2008-03-01 17:31] installed inside a Guest Computer to improve its performance and
[2008-03-01 17:31] cooperation with the rest of the Product. In addition to and independent

"Whatever can go wrong, will go wrong" - Murphy's law
Anywho, I guess a quick check for # of fields would fix this.

EDIT: For those of you that don't have python (I assume this is less than a handfull), here's an awk solution.

awk 'NF>7{next} $3~/installed|upgraded/{a[$4]} $3~/removed/{delete a[$4]} END {for (x in a){print x}}' /var/log/pacman.log |sort

The 'awk' script by 'sabooky' is very neat and worked well.

The 'python' script by 'Pierluigi' was also good, but failed because my "pacman.log" has some lines with only two words. Here's a slightly modified version:

#!/usr/bin/env python
#
# pacfix.py: a script by pierluigi to list all the packages currently installed according to /var/log/pacman.log
#            2008-07-04: Modified by Chris Giles to prevent failure when "pacman.log" has lines with only two words


pkg=[]

logfile = open("/var/log/pacman.log","r")
#logfile = open("./pacman.log","r")
log=logfile.readlines()
for myline in log:
    myarray = myline.strip("\n").split(" ")
    if len(myarray) >= 3 :
        if (myarray[2]=="installed" or myarray[2]=="upgraded"):
            if (pkg.count(myarray[3])==0):
                pkg.append(myarray[3])
        if (myarray[2]=="removed"):
            if (pkg.count(myarray[3])!=0):
                pkg.remove(myarray[3])
pkg.sort()
for p in pkg:
    print p
