Long Repo Sync

Ever had to do a very loooooong repo sync?

What if it breaks in the middle by network problems?

Created a little script to help you with that.

It will download 1 project at a time minimizing errors.
It logs every project synced in a "log.txt" with a status beside each one.

If you have errors , just re-execute the script , it will read the "log.txt" and try to resync bad projects.

All you need to do is run the script in the folder where .repo was created.


#!/bin/bash

FILE=".repo/manifest.xml"

if [ -e "./log.txt" ] ; then
        cat ./log.txt | grep Error >> newlog.txt
        while read line ; do
                check=`echo $line | grep "Error"`
                if [ ! -z "$check" ] ; then
                        name=`echo $line | awk '{ print $2 }'`
                        echo "Resyncing project=$name"
                        repo sync $name > output.txt 2>&1
                        check=`cat output.txt | grep "From ssh:"`
                        if [ ! -z "$check" ] ; then
                                end=`cat output.txt  | grep "fatal"`
                                if [ -z "$end" ] ; then
                                        echo "Project= $name Status=Done" >> log.txt
                                else
                                        echo "Project= $name Status=Error" >> log.txt
                                fi
                        else
                                echo "Project= $name Status=Already Synced" >> log.txt
                        fi

                fi
        done < ./newlog.txt
        rm -f ./log.txt ./newlog.txt

        if [ ! -z  "$PROJECT" ] ; then
