SVN UN-delete

If you want to recover any folder or file which was deleted accidentally  you can recover the same. First you need to figure out the revision number when it was deleted. Now use this command on server to get back file/folder .

Remember even if you perform delete operation in SVN nothing gets deleted it is just omitted from future checkout's and updates.


 svn cp -r 47 https://amit.example.com/svn/repos/test_repo/data/somefolder/Debug  https://amit.example.com/svn/repos/test_repo/data/somefPublish Postolder/

Code Freeze SVN

To implement Code freeze in SVN you can write pre-commit hook script. Here is a sample script which does this job on specified paths. You please remove all echo in case implementing on production.


REPOS="$1"
TXN="$2"

echo "value of REPOS is :$REPOS"  >> /svnroot/test_repo_precommit/hooks/precommit.log
echo "value of TXN is :$TXN"  >> /svnroot/test_repo_precommit/hooks/precommit.log

REPO_URL_TO_MATCH=(
                '/svnroot/test_repo_precommit/somepath1'
'/svnroot/test_repo_precommit/somepath2'
'/svnroot/test_repo_precommit/somepath2'
);

echo "printing REPO_URL_TO_MATCH array values : ${REPO_URL_TO_MATCH[@]}"  >> /svnroot/test_repo_precommit/hooks/precommit.log

for REPO_URL_TO_MATCH in ${REPO_URL_TO_MATCH[@]}
do

echo  "in for loop print REPO_URL_TO_MATCH :$REPO_URL_TO_MATCH" >> /svnroot/test_repo_precommit/hooks/precommit.log;

RESULT1=`svnlook dirs-changed "$REPOS" -t $TXN | grep -e "$REPO_URL_TO_MATCH"`;

echo " printing value of RESULT1 : $RESULT1"  >> /svnroot/test_repo_precommit/hooks/precommit.log;

for pattern in $RESULT1
do
 if [ ! -z "$pattern" ];
echo " Value of pattern is :$pattern " >> /svnroot/test_repo_precommit/hooks/precommit.log

then
echo "*** Your commit has been blocked because code is in freezed mode, Please contact repo administrator to remove code freeze from this path."
exit 1
fi
done
echo "Exit from Loop one " >> /svnroot/test_repo_precommit/hooks/precommit.log

done
echo `date` >> /svnroot/test_repo_precommit/hooks/precommit.log
echo "*********************This is end of script************************************" >> /svnroot/test_repo_precommit/hooks/precommit.log

Lives we are making Simple / Complicated

I have to go to office in morning and i am writing this post as i am not able to sleep :(


Have you ever thought that why we work.......other than Salary .. What value we are adding to this world by working. May be are trying to make things better and simpler, and in order to do that in most efficient (in term of cost\time ) we are making things more complex.

I am a System Admin, right now handling a Application support.  Application which supports developers to manage there code and help project manager to plan for projects.

These developers are writing code for their clients may be banking , telecom , those companies are again working to provide me better services and see what, indirectly am doing all for my comfort.

This circle made me understand a lot of things that if i will not give good service i am not going to get good service. 

But am i really in comfort am i actually enjoying life, am i really earn to live, seems like i am living to earn.
Life seems to be like an race, we humans are again living like animals prisoners to our schedule.

Some time i really think about life in past, we have been trying to make out lives better, are we successful enough to do this, are we living a better life, writing this blog sitting on my laptop gives me feel definitely things have changed and are much better from past, than why it happens that feeling of fulfillment is not there, there are something missing, something incomplete.

If only i was again a 6 Year old child and make excuse of stomach ace for not going to school. :(

Start a Political party

Here are the things which can be implemented to start a political party. I am writing this because of my low memory. Idea's flash in my mind and than they disappear as they were never there.  I as such don't have intention of starting a political party but i think things mentioned over here are surly going to work to win you at least one election later on all depends upon the work you do.

=> People are fed of system and 50% of India doesn't VOTE. NEVER ASK THEM TO VOTE FOR YOU rather ask them to just VOTE. Start a campaign in which ask people to VOTE, ask them to join you in movement to choose a right candidate and there should be a option of choosing NO candidate. Change and reforms in Elections is 1st thing, bring this in front of people. In your campaign publish 49-O as much as possible.

try to convince people not to give vote in influence of liquor or money offered.
=> Never made any promises, people don't have faith in promises.
=>Stand against reservation this will bring a big vote bank. tell them you will not give them bread but skills by which they can earn bread.
=>Publish bio-data of your candidates not the pictures, tell them how successful they already are in there lives, you need to convey that they are not in politics for money and power. Publish there wealth assets on your website.

=>ask for donation and funds to make them believe that you don't have corporate support with you.
=> Pitch for change in there social life conditions.
=> Bring issue that how politicians make rules and laws for common men which do not implement on them. Bring example of BRT corridor. Tell them your party workers will move in same lanes in which they are moving.
=> Justice delayed is Justice denied - tell them you are going to bring reforms in our courts. (THIS IS THE BIGGEST POINT TO CASH ON)
=>RTI will be available over phone.
=> your local constituency expenses made available to all in a form of news paper to all once in 6 months.
=>MCD complaints will handled over phone, all pit holes to filled in 48 hrs of reporting.
=> bring as much as local issues to pictures which effect the common men directly.
=>Common men (Middle class) people are the key to WIN elections.
=> Just don't tell what are you going to do tell people how you are going to do that. (People don;t believe un-realistic promises)

* You need to find people who can fund you for TV advertisement.
* You need to find people you will stand with you fight elections with you.
