Update contribs

Backgrund

Due to dependencies, the installation of contribs requires very often the installation of rpms coming from other repositories.

Updating the installed contribs needs sometimes to update the dependencies or sometimes only the dependencies get updated.

In order to avoid serious problems of compatibility, it is very important that all the rpms get updated only from the repository they are installed from, instead of only taking the most recent release existing in all the repositories that are available.

Yum doesn't do this job in one command but small scripts must be used for this purpose.

Scripts

3 scripts are available at this time:

script 1

#!/bin/bash

echo "List of available repos beside SME:";
#list the disabled repos
for repo in $(yum repolist disabled |awk  '$1 !~ /id|Modules|repolist:/ {print $1}'); do

     echo $repo;

done
echo "";

# repo selection
index=0;
repos="";
proceed="proceed";

until [ "$repos" == "$proceed" ]; do

       repos[$index]=$repos;
       ((index=index+1));
       read -p 'Enter 1x repo name for selection or "proceed" to start the updating: ' repos;

done

# remove the repo "proceed"
repos=("${repos[@]:1}");


for repo in "${repos[@]}"; do
       echo "";
       echo "======================================";
       echo -e "\tUPDATE from repo: "$repo;
       echo "======================================";

       # generate the list of rpm installed from the repo
       for rpm in $(/sbin/e-smith/audittools/newrpms |awk -v repo_awk=@$repo 'repo_awk==$3 {print $1}'); do

               rpms=$rpm' '$rpms

       done

	# updating
       yum --enablerepo=$repo update $rpms;

done

exit 0

Using this script is very easy:

• you get the list of all available repositories
• enter 1 by 1 the name of the repo you want to update from
• enter 'proceed' after the last repo
• for each repo, yum show the list of rpms that could be updated and ask (Y/N) before starting

eg.:

List of available repos beside SME:
centosplus
contrib
epel
extras
fasttrack
fws
remi
smecontribs
smedev
smetest
smeupdates-testing
sogo3

Enter 1x repo name for selection or "proceed" to start the updating: epel
Enter 1x repo name for selection or "proceed" to start the updating: fws
Enter 1x repo name for selection or "proceed" to start the updating: proceed

script 2

This script is much shorter, runs faster and doesn't require to enter the name of the several repos:

#!/bin/bash

for repo in $(/sbin/e-smith/audittools/newrpms |grep \@ |awk ' {print $3}' |sort -u |sed s/@//); do

       # generate the list of rpm installed from the repo
       for rpm in $(/sbin/e-smith/audittools/newrpms |awk -v repo_awk=@$repo 'repo_awk==$3 {print $1}'); do
               rpms=$rpm' '$rpms
       done

       echo -e "\n\n===";
       echo -e "Repo: "$repo;
       echo -e "\nIncludePkgs: "$rpms;
       echo "===";
       # updating
       yum --enablerepo=$repo --setopt="$repo.includepkgs='$rpms'" update

done

exit 0

The script

• runs 'newrpms' to get all repos that have been used to install non-standard packages
• creates a list of rpms for each such repo
• uses "--setopts" to specify "includepkgs" for each repo during update
• asks for Y/N and runs the update

script 3

This is similar to script 2, but modified to

• accept arguments
• default to "check-update -q"
• be less verbose

#!/bin/bash
if [ -z ${1+x} ]; then
        YUMCMD="check-update -q"
else
        YUMCMD="$*"
fi
for repo in $(/sbin/e-smith/audittools/newrpms |grep \@ |awk ' {print $3}' |sort -u |sed s/@//); do

        # generate the list of rpm installed from the repo
        for rpm in $(/sbin/e-smith/audittools/newrpms |awk -v repo_awk=@$repo 'repo_awk==$3 {print $1}'); do
                rpms=$rpm' '$rpms
        done

        if [[ ${YUMCMD} != *"-q"* ]]; then
                echo -e "\n\n===";
                echo -e "Repo: "$repo;
                echo -e "\nIncludePkgs: "$rpms;
                echo "===";
        fi
        # updating
        yum --enablerepo=$repo --setopt="$repo.includepkgs='$rpms'" $YUMCMD

done

exit 0

Notes:

• Using the default settings will list updates from the enabled repositories multiple times (once for each disabled repo with installed packages)
• Since this command starts from the output of /sbin/e-smith/audittools/newrpms, it is possible to get errors. That is, if you configure a repository, install a package from it, then remove the configuration, this script will error.
• Examples (assuming you have created /usr/local/bin/yumcheck.sh containing this script and made it executable)

yumcheck.sh

Check for updates for all packages installed from non-standard repos. Output info for packages that need updates

yumcheck.sh update

Run in verbose mode, do the updates, prompt the user after checking each repo if updates are pending

yumcheck.sh update -q -y

Show only those items to be updated, do the updates, and answer 'yes' to each suggested update.
