Q

Using a public key and a private key is known as what type of encryption?

The public key can be used to encrypt and the private key is used to decrypt.

Q

Explain how a JWT works and what the benefit of it is.

A

It works like a reverse asymmetric encryption. Appsec has a private key that they create a token with. Then, all apps can check the token against the public key which anyone can access to see if it is a valid token.

The benefit to this is that if appsec is down, previously generated tokens can still be checked with the public key to see if it is valid.

Q

Explain why a current months feature branch may be behind develop?

It could be behind develop because there may be long running feature work aka tier 1 work being pushed to develop and the current months feature branch wouldn’t have those changes yet.

Q

Explain how the hot fix process works.

A
  1. Branch off of master and call the branch release/X.X.1-lastReleasedMonth_WX.1

Note: The 1 should be an increase in the patch version.

  1. Branch off of that branch and call it bugfix/MPS-XXXXX-hotFix
  2. Once it is approved, merge your hotfix branch into the release/X.X.1-lastReleasedMonth_WX.1, which will automerge to any open month feature branches as well as develop.
  3. Merge the release/X.X.1-lastReleasedMonth_WX.1 branch into master.

Q

Explain all of the automatic merging situations that bitbucket does.

What is this all based on?

A

When you merge in to a monthly feature branch, it will be automatically merged into the next months feature branch, if it exists, and then to develop.

When you make a branch to do a hotfix off of, you will name it by increasing the patch version. When you merge your hotfix back into this branch, it will auto-merge to any open monthly release branches and then to develop.

It is all based on the versioning that is put into the branch names. Changes made to release branches with lower numbers in their name will auto-merge into any release branches that have higher version numbers in their name, as well as ultimately into develop.

Q

How many release branches will we have out at one time.

A

We don’t really want more than one out at a time but there may be two out at a time for a week or two.

For example, after FEB code freeze, we will make a MAR branch that we work off of while FEB is tested. We will only branch off of FEB if there is a bug fix that is needed.

Once FEB is released, the branch will be deleted and we will only have MAR open until the next code freeze.

If you have a problem with sourcetree not showing your local branch that you created from the terminal, what is the likely problem and solution?

A

You may have 2 different vehicle-android repos being tracked by sourcetree.

Quit it and come back into it and it should ask you what repo you want to look at. You want the one that has your current branch, so if you don’t need the other one, delete it.

26

First, make sure you are on the correct build variant.

Then try uninstalling all vehicle related apps via suite installer like condition, final check in, mCondition, etc. and then try to run.

Finally, you may try deleting all ehi apps via the suite installer and try again to run it.
