Until you commit the source code to the public branch of AGL (Automotive Grade Linux)
Purpose
This is a memorandum until you commit the source code to the public branch of AGL (Automotive Grade Linux).
Please refer to the following website for AGL.
Last time I launched the public binary of AGL on Raspberry Pi, This time I tried to commit the source code.
Launch AGL UCB 8.0.0 announced on August 22, 2019 with Raspberry Pi 3B +
Preparation
The source code of AGL is open to the public, and anyone can become a Contributor.
First, do the following as described in the Guideline above.
-
- Create an account for linuxfoundation.org
- Join the mailing list
-
- Create Gerrit account
Prerequisites
- Create an account on identity.linuxfoundation.org to get started.
- Join the mailing list.
- Setup your Gerrit account, as described in the Gerrit Tutorial from mediawiki
Next, get the source code as follows and read the contents in various ways. Since it is difficult to add functions suddenly, we will check from the perspective of whether we can contribute by fixing expired links or building warnings.
The Easy Way for Commit is also introduced below.
Use-Regression-Testing-to-Make-AGL-Better Easy Way I: • Update outdated documents. Easy Way II: • Remove build error and warning. AGL-REGRESSION-TEST-TEMPLATE
Code acquisition
Repo sync referring to the following.
Repo sync the source code
I was able to get the source code in the following 3 steps. (* Subject to change, please be sure to refer to the above link for details)
1. Define Your Top-Level Directory
$ export AGL_TOP=$HOME/workspace_agl
$ mkdir -p $AGL_TOP
2. Download the repo Tool and Set Permissions
$ mkdir -p ~/bin
$ export PATH=~/bin:$PATH
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo
3. Download the AGL Source Files:
$ cd $AGL_TOP
$ repo init -u https://gerrit.automotivelinux.org/gerrit/AGL/AGL-repo
$ repo sync
Code creation for commit
It is difficult to add functions suddenly, so check from the perspective of whether you can contribute something by fixing expired links or building warnings.
For example, the following is an example of correcting an expired link. ~ 2. There seems to be.
-
- Prepare a script to check for broken URL links.
Create a python script to check if the link at the specified URL is valid
- Get the character string starting with https from the text file on the source code as shown below, Check if the link is broken. You may find broken links in such cases.
$ cd agl-halibut-8.0.1
$ grep -rn "https:" * > out.txt
$ cat out.txt | cut -d '=' -f 2 | cut -d ' ' -f 2 | cut -d '"' -f 2 | grep "https" | grep -v "meta" | grep -v "]" > out2.txt
Preparation for commit
During the AGL code release You will commit to CIAT, a continuous integration rating system.
The following is detailed about CIAT.

Gerrit is a review system, and commits are finally merged with Expert Member approval. It also performs an automatic evaluation. On Gerrit, it is described as follows.
CR : Code review
V : Verified
CIB : ci-image-build
CIBT : ci-image-boot-test
commit procedure
As described in the Contributor Guidelines, proceed with the commit of the difference code by referring to the following.
--Prepare to push changes in Gerrit chapter in Contributor Guidelines --Push changes for review to Gerrit chapter in Contributor Guidelines

Contributor Guidelines Push changes for review to Gerrit
You have successfully approved the commit
When I committed a simple URL link correction, After successfully completing the review, it became a Merged Status.
Commit message
It's important to write a Commit message that is a way to tell the other person what changes you have made. It is especially important to communicate your intentions to someone you have never interacted with remotely. How to Write a Git Commit Message
Impressions
While the AGL code is widely available, I think it's great to have a system in place to thoroughly review quality. Also, committing to open source, not just AGL code, will help you broaden your insights. First of all, I think we should gradually contribute from the possible parts.
Error countermeasures
We don't know where your gerrit is. Please manually create a remote
gerrit public key, ssh config
To ssh://gerrit.automotivelinux.org:29418/AGL/meta-agl-devel
![remote rejected] HEAD -> refs/publish/master (commit dc81699: not Signed-off-by author/committer/uploader in message footer)
error: failed to push some refs to
You need to register your public key with gerrit.automotivelinux.org.
Also, please note that if you do not git commit signed off, an error will occur during git review.
