git push to upload commits - Step-by-Step Execution

Process Flow - git push to upload commits

Make local commits

↓

Run 'git push'

↓

Connect to remote repo

↓

Upload commits

↓

Update remote branch

↓

Confirm success or error

This flow shows how local commits are sent to the remote repository using 'git push'.

Execution Sample

Git

git add .
git commit -m "Add new feature"
git push origin main

This sequence stages changes, commits them locally, then pushes to the remote 'main' branch.

Process Table

Step	Action	Evaluation	Result
1	git add .	Stage all changes	All changes staged for commit
2	git commit -m "Add new feature"	Create local commit	New commit created locally
3	git push origin main	Connect to remote 'origin' and branch 'main'	Connection established
4	git push origin main	Upload local commits to remote	Commits uploaded
5	git push origin main	Update remote branch pointer	Remote 'main' branch updated
6	git push origin main	Confirm push success	Push completed successfully

💡 Push stops after commits are uploaded and remote branch is updated successfully

Status Tracker

Variable	Start	After Step 1	After Step 2	After Step 4	Final
Staged Changes	none	all changes staged	none	none	none
Local Commits	none	none	1 new commit	1 new commit	1 new commit
Remote Branch	at old commit	at old commit	at old commit	updated to new commit	updated to new commit

Key Moments - 3 Insights

Why do I need to commit locally before pushing?

Because 'git push' only uploads commits that exist locally. Without a local commit, there is nothing to push (see execution_table steps 2 and 4).

What happens if the remote branch has new commits I don't have?

The push will be rejected until you pull and merge those commits locally. This is not shown here but is important to avoid conflicts.

Does 'git push' upload all my changes automatically?

'git push' uploads only committed changes. Unstaged or uncommitted changes are not pushed (see variable_tracker for staged vs committed).

Visual Quiz - 3 Questions

Look at the execution table, what is the result after step 3?

A Local commits are uploaded

B Remote branch pointer is updated

C Connection to remote repository is established

D Push completed successfully

💡 Hint

Check the 'Result' column for step 3 in the execution_table

At which step does the remote branch get updated?

A Step 4

B Step 5

C Step 2

D Step 6

💡 Hint

Look at the 'Action' and 'Result' columns in the execution_table for when the remote branch pointer changes

If you skip 'git commit', what will happen when you run 'git push'?

A Push will fail because there are no new commits

B Push will upload previous commits only

C Push will upload all unstaged changes

D Push will create a new commit automatically

💡 Hint

Refer to key_moments about the need for local commits before pushing

Concept Snapshot

git push uploads local commits to a remote repository.
Syntax: git push <remote> <branch>
You must commit changes locally before pushing.
Push updates the remote branch pointer.
If remote has new commits, pull first to avoid conflicts.

Full Transcript

This visual execution shows how 'git push' works step-by-step. First, changes are staged with 'git add'. Then a local commit is created with 'git commit'. When 'git push' runs, it connects to the remote repository and uploads the new commits. Finally, the remote branch pointer updates to the latest commit. The push ends successfully after these steps. Remember, only committed changes are pushed. If the remote has new commits you don't have, the push will be rejected until you pull and merge. This trace helps beginners see the exact flow and state changes during a push.

Practice

1. What does the git push command do in Git?

easy

A. Uploads your committed changes to a remote repository

B. Downloads changes from a remote repository

C. Creates a new branch locally

D. Deletes files from your local repository

Solution

1. Step 1: Understand the purpose of git push

   The git push command sends your committed changes from your local repository to a remote repository, like GitHub.

2. Step 2: Differentiate from other commands

   Commands like git pull download changes, and git branch manages branches, so they do not upload commits.

3. Final Answer:

   Uploads your committed changes to a remote repository -> Option A

4. Quick Check:

   git push uploads commits [OK]

Hint: Push sends commits to remote repo, pull downloads from it [OK]

Common Mistakes:

• Confusing push with pull
• Trying to push uncommitted changes
• Using push to create branches

2. Which of the following is the correct syntax to push your current branch to the remote named origin?

easy

A. git push origin current_branch

B. git push origin

C. git push origin HEAD

D. git push current_branch origin

Solution

1. Step 1: Understand default push behavior

   Running git push origin HEAD pushes the current branch to the remote named origin explicitly by referencing HEAD.

2. Step 2: Analyze other options

   git push origin current_branch requires you to replace current_branch with the actual branch name; git push origin pushes the current branch but may depend on configuration; git push current_branch origin is incorrect order.

3. Final Answer:

   git push origin HEAD -> Option C

4. Quick Check:

   Explicitly push current branch with HEAD [OK]

Hint: Use git push origin HEAD to push current branch explicitly [OK]

Common Mistakes:

• Swapping remote and branch names
• Using HEAD without understanding
• Omitting remote name

3. Given the following commands run in order:

git add file.txt
git commit -m "Update file"
git push origin main

What will happen after the last command?

medium

A. An error occurs because the branch name is missing

B. The changes in file.txt are uploaded to the remote main branch

C. The changes are saved locally but not uploaded

D. The remote repository deletes file.txt

Solution

1. Step 1: Confirm commit preparation

   git add stages the file, and git commit saves the changes locally in a commit.

2. Step 2: Understand git push origin main

   This command uploads the committed changes to the remote repository's main branch.

3. Final Answer:

   The changes in file.txt are uploaded to the remote main branch -> Option B

4. Quick Check:

   Commit then push uploads changes [OK]

Hint: Commit first, then push to upload changes [OK]

Common Mistakes:

• Pushing without committing first
• Using wrong branch name
• Expecting push to stage files

4. You run git push origin main but get the error: error: failed to push some refs to 'origin'. What is the most likely cause?

medium

A. Your local repository is empty

B. You have uncommitted changes locally

C. You typed the remote name incorrectly

D. The remote main branch has new commits you don't have

Solution

1. Step 1: Understand the error meaning

   This error usually means your local branch is behind the remote branch because the remote has new commits you haven't pulled yet.

2. Step 2: Identify the fix

   You need to run git pull origin main to update your local branch before pushing again.

3. Final Answer:

   The remote main branch has new commits you don't have -> Option D

4. Quick Check:

   Push fails if remote has newer commits [OK]

Hint: Pull before push if remote has new commits [OK]

Common Mistakes:

• Ignoring need to pull first
• Assuming uncommitted changes cause push failure
• Mistyping remote name without checking

5. You want to push your local branch feature to the remote origin and set it to track the remote branch. Which command should you use?

hard

A. git push -u origin feature

B. git push feature origin -u

C. git push origin -u feature

D. git push origin feature

Solution

1. Step 1: Understand tracking branches

   Using -u or --set-upstream sets the local branch to track the remote branch, making future pushes easier.

2. Step 2: Identify correct command syntax

   The correct syntax is git push -u origin feature, where -u comes before the remote and branch names.

3. Final Answer:

   git push -u origin feature -> Option A

4. Quick Check:

   Use -u before remote to set tracking [OK]

Hint: Use git push -u origin branch to set tracking [OK]

Common Mistakes:

• Placing -u after remote or branch
• Forgetting to set upstream for new branches
• Mixing order of arguments
