Development Notes about git and ways to stay up to date of source code changes

Branches[edit]

Introduction[edit]

While the project is small adrelanos thinks it is best not to make a too difficult policy.

Compare[edit]

Upstream git issue. Currently not easy to compare tags in a superproject while showing what changed in the submodules.

git log -p --submodule=log 15.0.0.3.3-stable..15.0.0.3.7-developers-only

master[edit]

  • Adrelanos's progress of work.
  • Not calling it unstable, because the changes will most likely never make it unstable but it is just not tested if it still builds.
  • Branching model, project readme, information, gpg...

signed git tags[edit]

Releases will be tagged and gpg signed.

Link to Source Code[edit]

https://github.com/Kicksecure/derivative-makerarchive.org

subscribe to code changes[edit]

git[edit]

Git clone githubarchive.org.

A git specific work flow could be: 

git fetch

every (few) day(s) and then git diff(tool), merge, etc.

rss feed notification[edit]

https://github.com/Kicksecure/derivative-maker/commits/master.atomarchive.org

manually in your browser[edit]

Check every now and then https://github.com/Kicksecure/derivative-maker/commits/masterarchive.org.

Search the Source Code[edit]

Introduction[edit]

greping (search for keywords inside files) or finding files the Kicksecure source code can be useful when looking for certain keywords or files. However, a common grep -r or find . will show lots of irrelevant search results due to changelog files, license files and git history. The following is a suggestions on how to securely acquire Kicksecure source code as well as on greping or finding the Kicksecure with relevant only relevant search results.

Get the Source Code[edit]

Get the Signing Key[edit]

Info This step is recommended for better security, but is not strictly required. (See Trust.)

Get the Kicksecure Signing Key and import it.

Get the Source Code[edit]

FREE

Note: By proceeding, you acknowledge that you have read, understood and agreed to our Terms of Service and License Agreement.

1. Install git.

sudo apt update && sudo apt install git

2. Get the source code including git submodules. [1] [2]

Note: Replace 17.2.0.1-stable with the actual tag you want to build.

git clone --depth=1 --branch 17.2.0.1-stable --jobs=4 --recurse-submodules --shallow-submodules https://github.com/Kicksecure/derivative-maker.git

3. Check if above command succeeded.

If there have been errors such as: 

fatal: unable to access 'https://github.com/.../': Could not resolve host: github.com

Or. 

fatal: unable to access 'https://github.com/.../': gnutls_handshake() failed: The TLS connection was non-properly terminated.

Then the download probably failed.

Checking if the download failed or succeeded can be done by checking the exit code.

Choose your shell.

Zsh in Kicksecure or Derivatives

If the last line contains something such as the following. 

zsh: exit 1

Then do not proceed and see footnote. [3]

bash and other Shells

Show the exit code.

echo $?

Output should show. 

0

If any other exit code is shown, do not proceed and see footnote. [3]

4. Done.

Git repository cloning has been completed.

OpenPGP Verify the Source Code[edit]

This chapter is recommended for better security, but is not strictly required. (See Trust.)

  • Digital signatures: A tool enhancing download security. Commonly used across the internet.
  • Learn more: Curious? Learn more about digital software signatures.
  • Optional: Digital signatures are optional. If you've never used them before, there might be no need to start now.
  • No worries: New to digital software signatures? It's okay, no need to worry.
  • Not a requirement: Not mandatory for using Kicksecure, but an extra security measure for advanced users.

1. Verify the chosen tag to build.

Note: Replace with tag you want to build.

git verify-tag 17.2.0.1-stable

The output should look similar to this. 

gpg: Signature made Mon 11 Mar 2024 01:51:56 PM EDT
gpg:                using RSA key 6E979B28A6F37C43BE30AFA1CB8D50BB77BB3C48
gpg:                issuer "adrelanos@whonix.org"
gpg: Good signature

warning Remember to check the GPG signature timestamp. For instance, if you previously saw a signature from 2023 and now see one from 2022, this could indicate a potential rollback (downgrade) or indefinite freeze attack.[4]

2. Verify the git commit to build. [5]

Note: Replace 17.2.0.1 with the actual git tag being verified.

git verify-commit 17.2.0.1-stable^{commit}

The output should look similar to this. 

gpg: Signature made Mon 11 Mar 2024 01:51:56 PM EDT
gpg:                using RSA key 6E979B28A6F37C43BE30AFA1CB8D50BB77BB3C48
gpg:                issuer "adrelanos@whonix.org"
gpg: Good signature

3. Done.

Choose Version[edit]

1. Retrieve a list of available git tags.

git --no-pager tag

2. Use git checkout to select the preferred version to build.

Note: Replace 17.2.0.1-stable with the actual version chosen for the build: the stable, testers-only or developers version. Common sense is required when choosing the right version number. For example, the latest available version number is not necessarily the most stable or suitable. Follow the Kicksecure News Blog as it might contain information.

git checkout --recurse-submodules 17.2.0.1-stable

3. Digital signature verification.

Optional. If you choose to perform digital signature verification above, you could verify the currently chosen commit ("HEAD") yet again for extra security.

git verify-commit HEAD

4. Done.

Version selection has been completed.

Check Git[edit]

1. Check if you really got the version you want.

git describe

The output should show.

17.2.0.1-stable

2. Check if source folder is pristine.

git status

Output should be the following.

  • A)

HEAD detached at 17.2.0.1-stable
nothing to commit, working tree clean
or,

  • B)
Not currently on any branch.
nothing to commit, working tree clean

If it shows something else, do not continue.

3. Done.

Find Keywords[edit]

1. Create folder ~/bin.

mkdir -p ~/bin

2. Create a file ~/bin/mygrep.

3. Paste the following content.

#!/bin/bash set -x grep \ --exclude=README.md \ --exclude=GPLv2 \ --exclude=GPLv3 \ --exclude=COPYING \ --exclude=changelog.upstream-old1 \ --exclude-dir=mnt \ --exclude-dir=qubes-src/linux-template-builder/mnt \ --exclude=changelog.upstream \ --exclude-dir=".git" \ --exclude-dir=chroot-debian \ --exclude-dir=chroot-buster "$@"

4. Save.

5. Make executable.

chmod +x ~/bin/mygrep

6. Reboot required.

7. You need to be inside the source code folder. If not already, change directory.

cd derivative-maker

8. Search for a textual string (keyword).

For example grub-pc. Replace grub-pc with the actual keyword.

mygrep -r -i grub-pc

Find Files[edit]

1. Create folder ~/bin.

mkdir -p ~/bin

2. Create a file ~/bin/myfind.

3. Paste the following.

#!/bin/bash set -x find \ "$@" \ -type f \ -not -iwholename '*.git*'

4. Save.

5. Make executable.

chmod +x ~/bin/myfind

6. You need to be inside the source code folder. If not already, change directory.

cd derivative-maker

7. Search for a file name.

For example /etc/apparmor.d.

myfind . | grep --color -i /etc/apparmor.d

Compiled Code[edit]

find . -name '*.c' -not -iwholename '*.git*' 

./sdwdate/usr/lib/sdwdate/sclockadj.c
./bindp/usr/lib/bindp.c
./kloak/src/main.c
./kloak/src/keycodes.c
./kloak/src/eventcap.c

Put folder under Git Version Control[edit]

Operating System Software and Updates

sudo apt update

Install git.

sudo apt install --no-install-recommends git

Unless you want to use git for pushing changes to remotes which you probably won't in a testing VM you can use the following git config without using any real names or pseudonyms. (These are the git suggested defaults. [6])

git config --global user.email "you@example.com"

git config --global user.name "Your Name"

Desalinize git in current folder or cd to any folder you want to put under git version control. Can even be done for /home/user folder which is very useful.

git init

Add all files to be added for next commit.

git add -A

Actually commit to git.

git commit -a -m .

Check git status of that folder.

git status

No changes registered yet to the folder since just now committed all to git. 

On branch master
nothing to commit, working tree clean

Create a test file or do some activity such as starting a browser or e-mail client.

touch test-file

Check again git status of that folder.

git status

Now git will show what changed. 

On branch master
Untracked files:
  (use "git add <file>..." to include in what will be committed)

	test-file

nothing added to commit but untracked files present (use "git add" to track)

Goodies[edit]

Optional. Just sharing. Like it or not.

screenshotarchive.org

apt source[edit]

You need to enable deb-src in /etc/apt/sources.list.d/derivative.list! 

sudo apt update

There is nothing in these repositories and it does not limit functionality in any way. This is an inconvenient message but it will not be fixed since it was only raised once in that last five years.

apt source is fully functional. 

apt source sandbox-app-launcher

Footnotes[edit]

  1. ↑ Optional git parameters:
    • --depth=1: Used to speed up the download.
    • --branch 17.2.0.1-stable: Usability. Used to speed up the download.
    • --jobs=4: Used to speed up the download.
    • --recurse-submodules --shallow-submodules: Usability.
    Knowledgeable git users are free to drop any of these optional parameters.
  2. ↑ Alternatively, this can be achieved with the following commands in several steps. This is useful if network issues arise.
    • Over HTTPS:
      • git clone --depth=1 --branch 17.2.0.1-stable https://github.com/Kicksecure/derivative-maker.git
    • Over SSH.
      • Might work better over slow networks but requires a GitHub account and a configured SSH public key at GitHub. See footnote [A] below.
      • git clone --depth=1 --branch 17.2.0.1-stable git@github.com:Kicksecure/derivative-maker.git
    cd derivative-maker git submodule update --init --recursive --progress --jobs=4

    [A] GitHub SSH public key setup.

    1. You need to create an SSH public key.

    Undocumented.

    2. You view your your SSH public key.

    cat ~/.ssh/id_ed25519.pub

    3. Copy it.

    4. And paste your the SSH public key on GitHub.

    https://github.com/settings/keysarchive.org

  3. ↑ 3.0 3.1 Delete the derivative-maker source code folder and retry. 
    sudo rm -r derivative-maker
  4. ↑ As defined by TUF: Attacks and Weaknesses:
  5. ↑ It is advisable to verify the signature of the git commit as well. By convention, git tags should point to signed git commits. Beginning from git tag 9.6 and above. (forum discussionarchive.org)
  6. ↑ 
    git commit -a -m .

*** Please tell me who you are.

Run

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

fatal: empty ident name (for <(null)>) not allowed
