* Introduction to CodeQL
|
||||
1. [ ] describe the system using diagrams as reference point, with details from
|
||||
existing docs
|
||||
- https://github.com/hohn/codeql-visual-guides/blob/master/codeql-system.drawio.pdf,
|
||||
~/work-gh/codeql-visual-guides/
|
||||
|
||||
2. Update https://github.com/hohn/codeql-cli-end-to-end
|
||||
- [ ] Send setup instructions for windows / linux -- for the laptops, not
|
||||
VMs or Docker.
|
||||
- old:

|
||||
- octopuss deploy
|
||||
- progit for package management -- anito.
|
||||
- Actions for building

* CodeQL overview

- /Users/hohn/local/codeql-dataflow-sql-injection/CodeQL-workshop-overview-only.pdf
|
||||
|
||||
There are two identifyable tracks for codeql users: [[*CodeQL for Devops and Administrators][devops]] and [[*CodeQL for Query Writers][query writers]].
|
||||
The first one focuses on setup, deployment, and query selection; the second on
|
||||
query writing. There is significant overlap; the [[*CodeQL CLI Setup][CodeQL CLI Setup]] is needed by
|
||||
both.
