Tizen Development Workflow (1/3) SKKU Embedded Software Lab. 5 75
Tizen Development Workflow (2/3) 1. Local works by Developers 1. Setting up Tizen development environment 2. Cloning the source code 3. Changing and verifying local source code through local build 2. Review 1. Submission : Developer submits patches to review server for stakeholders to review 2. Verification : Tizen backend service and reviewers verify the patches through testing process and then vote based on the quality of the patches. 3. Approval and Merge : Maintainers approve the patches and then merge code changes to the review server’s repository. SKKU Embedded Software Lab. 6 75
Tizen Development Workflow (3/3) 7 3. Release – 1. 2. 3. 4. Tizen backend service activates pre-release and normal release processes at the same time. Submission on OBS : Maintainers/Developers submit packages to the OBS by using gbs submit command. Pre-release : Tizen images that incorporates specific packages are created and submitted to release engineers to review. Final review : Release engineers accept or reject submissions based on the quality of the packages. Accepted source code is merged into the OBS repository. Release : the normal release process takes over and publishes repos together with Tizen images. SKKU Embedded Software Lab. 75
SCM Tools (1/3): Git 8 • A revision control and source management tool • Features – – – Free and open source(GNU GPL v 2) Smaller and faster than other SCM tools Distributed Branching and merging Data assurance Staging area • Git in Tizen – All source code repositories of Tizen packages are managed by git. SKKU Embedded Software Lab. 75
SCM Tools (2/3): Repo 9 75 • Repository management tool built top of Git on – Originally used in Android project – Used for managing many git repositories – Automate parts of development workflow • Repo in Tizen – Tizen platform is composed of the hundreds of projects. – Each projects are managed as a git repository. – Repo is used for managing Tizen platform repositories in batched manner. • ex. Cloning git repositories of entire Tizen platform packages SKKU Embedded Software Lab.
SCM Tools (3/3): GBS 10 75 • Git Build System • A developer command line tool that supports Tizen package development • Functions – – Builds a repository or repositories and make package files(*. rpm) Generates tarballs based on Git repositories Does local test buildings Submits source code to OBS(Tizen’s main build service) SKKU Embedded Software Lab.
Centralized SCM System • Gerrit ( review. tizen. org ) – A Web-based code review system • OBS(Open Build System; build. tizen. org ) – A distributed development platform that makes developers to easily release open source software for various Linux distributions on different hardware architectures. SKKU Embedded Software Lab. 11 75
Packaging Tools: RPM and MIC 12 75 • RPM(Red Hat Package Manager) – A tool to manage software packages • build, install, query, verify, update and erase software packages – RPM in Tizen • Each Tizen platform package is represented in *. rpm form and managed by RPM. • MIC(Moblin Image Creator) – A tool to create platform images to be flashed on target device’s storage – Requires: • Tizen platform packages (*. rpm) • Kickstart file: it defines how to make image of target device – Output: platform images(system. img, userdata. img, ums. img) SKKU Embedded Software Lab.
13 75 1. Tizen Development Environment A. Tizen Development Overview B. Tizen Source Code Management C. Installation SKKU Embedded Software Lab.
Tizen Source Code Workflow 1. Git: manages source code versions 2. GBS: builds source code of git repository → makes package file(RPM) 3. Install package file on ODROID-U 3 SKKU Embedded Software Lab. 14 75
Git: Key Concepts • Working directory – Source code in work – “add” command: adds files/directories to staging area • Staging area(index) – Source code to be committed – “commit” command: makes a new version in repository • Repository(HEAD) – Source code already committed – Files or directories are stored as contentaddressable objects identifiable by hash value. SKKU Embedded Software Lab. 15 75
Version Management (1/2) • Add a source code, ‘hello. cpp’ 1. Add hello. c to staging area 1. $ git add hello. c 2. Make a new version 1. $ git commit -m “commit message” • Add all of the source code 1. $ git add --all 2. Make a new version 1. $ git commit -m “commit message” • Display staging area’s status 1. $ git status SKKU Embedded Software Lab. 16 75
Version Management (2/2) 17 75 • Display the commit log 1. $ git log – Each commit’s hash value, author information, date, message commit 783 c 82 ff 64 eda 9 f 03401834 de 906 eca 77 d 01 f 691 Author: Gyeonghwan Hong <redcarrottt@gmail. com> Date: Mon Sep 22 10: 37: 44 2014 +0900 2 nd version commit: hello. c is added commit 712943 bb 31 bf 85430 e 1 a 027 abe 197 e 5 b 88 a 26110 Author: Gyeonghwan Hong <redcarrottt@gmail. com> Date: Thu Aug 28 12: 08: 17 2014 +0900 1 st version commit: hello. h is added • Return to a previous version 1. git checkout <commit’s hash value> – ex. git checkout 712943 bb 31 bf 85430 e 1 a 027 abe 197 e 5 b 88 a 26110 SKKU Embedded Software Lab.
Local & Remote Repository (1/2) • “Commit” – Make a new version on local repository • “Push” – Upload commits in local repository to remote repository • “Pull” – Download commits in remote repository to local repository SKKU Embedded Software Lab. 18 75
Local & Remote Repository (2/2) • Upload to remote repository 1. $ git push <remote name> <remote branch> – ex. $ git push origin master • Download from remote repository 1. $ git pull SKKU Embedded Software Lab. 19 75
Branch Management (1/3) • Check the branch list of local repository 1. $ git branch --list • Check the branch list of remote repository 1. $ git branch --remote * master feature_x • Move to another branch 1. $ git checkout <branch name> – ex. $ git checkout feature_x SKKU Embedded Software Lab. 20 75
Branch Management (2/3) • Develop a new feature by making a new branch 1. Make a new branch ‘feature_x’ 1. $ git branch feature_x 2. $ git checkout feature_x 2. Edit and commit source code 3. Merge ‘feature_x’ branch to original branch 1. $ git checkout master 2. $ git merge feature_x SKKU Embedded Software Lab. 21 75
Branch Management (3/3) 22 • Conflict – When merging feature_y branch to master branch, ‘hello. h’ in version 2 -x and 2 -y have different changes each other. – This situation is called as ‘conflict ’. – The conflict should be resolved by ‘conflict resolution’ process. 1. $ git mergetool • http: //git-scm. com/book/en/v 2/Git-Branching-Basic-Branching-and.
