Git: Pushing to other fork

Objective:

You clone someone else fork and wants to push in your fork

I created a fork (let’s call it myrepo) of another repository (let’s call it orirepo) on GitHub. Later, I cloned orirepo.

git clone https://github.com/original/orirepo.git

I modified about 20 files, then I staged my change and made a commit

git add
git commit

However, when I tried to push

git push

I got this error:

remote: Permission to original/orirepo.git denied to mylogin.
fatal: unable to access 'https://github.com/original/orirepo.git/': The requested URL returned error: 403

 

Solution:

By default, when you clone a repository

• that resides at https://github.com/original/orirepo.git,
• whose current branch is called master,

then

• the local config of the resulting clone lists only one remote called origin, which is associated with the URL of the repository you cloned;
• the local master branch in your clone is set to track origin/master.

Therefore, if you don’t modify the config of your clone, Git interprets

git push

as

git push origin master:origin/master

In other words, git push attempts to push your local master branch to the master branch that resides on the remote repository (known by your clone as origin). However, you’re not allowed to do that, because you don’t have write access to that remote repository.

You need to

1. either redefine the origin remote to be associated with your fork, by running

   git remote set-url origin https://github.com/RemiB/myrepo.git
   

2. or, if you want to preserve the original definition of the origin remote, define a new remote (called myrepo, here) that is associated to your fork:

   git remote add myrepo https://github.com/RemiB/myrepo.git
   

   Then you should be able to push your local master branch to your fork by running

   git push myrepo master
   

   And if you want to tell Git that git push should push to myrepo instead of origin from now on, you should run

   git push -u myrepo master
   

instead.

Python: Quick script to create directory

Here is simple python code to smartly create a folder if it does not exisit

 

import os

def createFolder(directory):
    try:
        if not os.path.exists(directory):
            os.makedirs(directory)
    except OSError:
        print ('Error: Creating directory. ' +  directory)
        

# Example
createFolder('./data/')
# Creates a folder in the current directory called data

Python: printing on the same line (progress indicator)

In Java we have print which allow to print in same line
and println allow us to print on new line

But in python print always prints on new line, that makes it to difficult to print progress.

 

sys.stdout.write will print without return carriage

import sys
sys.stdout.write("progressing xxx")

Code running which needs to show progress
     sys.stdout.write(".")

QE: Cost of fixing bug

Python: Check if all elements in a list are equal

# Pythonic ways of checking if all
# items in a list are equal:

>>> lst = ['a', 'a', 'a']

>>> len(set(lst)) == 1
True

>>> all(x == lst[0] for x in lst)
True

>>> lst.count(lst[0]) == len(lst)
True

# I ordered those from "most Pythonic" to "least Pythonic" 
# and  "least efficient" to "most efficient". 
# The len(set()) solution is idiomatic,  but constructing 
# a set is less efficient memory and speed-wise.

Git: Combining the commits

To squash the last 3 commits into one:

git reset --soft HEAD~3
git commit -m "New message for the combined commit"

Pushing the squashed commit

If the commits have been pushed to the remote:

git push origin +name-of-branch

The plus sign forces the remote branch to accept your rewritten history, otherwise you will end up with divergent branches

If the commits have NOT yet been pushed to the remote:

git push origin name-of-branch

Certificate : Loopback course completion

Loopback is a very power api development framework on node.js. It allows you to build your entire api system with live api documentation ( swagger ) in a very fast and secure way. I finished this course and exposed few apis for some of my clients project.

Investing time and efforts is worth in this. Go for it.

 

This certificate above verifies that Aseem Jain successfully completed the course Node.js : Rest Apis Development Using Loopback on April 27, 2018 as taught by Haider Malik on Udemy. The certificate indicates the entire course was completed as validated by the student.
