@lexavtanke LGTM. What do you think of also providing a SHA256SUMS file so that the downloaded files can be tested against their checksums?

[lexavtanke]

@esteve Yes, make sense. I will switch it to draft for now and update.

[esteve]

@lexavtanke sorry I wasn't more specific. I meant adding a checksum file like this:

https://help.ubuntu.com/community/HowToSHA256SUM

so that users can check the files easily by running sha256sum -c SHA256SUMS, we might want to sign that file with GPG eventually as well.

[lexavtanke]

@esteve before I had started I also had this Idea because I wasn't sure. But I come to a conclusion that it will work for the first time and if user will update models manually one by one and will keep engines in the folders and run chechsum it can be confusing. After initial run of autoware user will have some additional files like trt engines.
Here is the example for lidar_centerpoint.

Do you think it will be better to push user to update all artifacts simultaneously? If so we will need to add a new playbook to ansible and modify setup-dev-env.sh or provide separate script for updating.

[esteve]

@lexavtanke I think it's fine if the models change because the user modifies them, but the first time they are downloaded it'd be useful for the user if they can verify the files easily (with sha2156 for example). Here's the SHA256SUMS file I generated locally:

I'm going to use it to update the ansible scripts so that all the files have a SHA256 sum (right now, some still a have an MD5 one)

[lexavtanke]

@esteve I've added SHA256SUM to README.

[esteve]

@lexavtanke I see, I meant a separate file, so that users can run sha256sum -c SHA256SUMS to check the integrity of the files. If they have to copy and paste the contents of README, they won't do it and it's also more difficult to automate.

[esteve]

The SHA256SUMS file can live in the same folder as the README, users can either download it so that it's in ~/autoware_data/SHA256SUMS or we can tell them to issue the following command:

$ cd ~/autoware_data/
$ wget -q -O - https://github.com/autowarefoundation/autoware/main/ansible/roles/artifacts/SHA256SUMS | sha256sum -c

@lexavtanke thank you so much for addressing my feedback 🙂
