* End-to-end example of CLI use
This document describes a complete cycle of the MRVA workflow. The steps
included are
1. aquiring CodeQL databases
2. selection of databases
3. configuration and use of the command-line client
4. server startup
5. submission of the jobs
6. retrieval of the results
7. examination of the results
* Database Aquisition
General database aquisition is beyond the scope of this document as it is very specific
to an organization's environment.
For this demo, the data is preloaded via container. To inspect it:
#+BEGIN_SRC sh
# On host, run
docker exec -it dbstore /bin/bash
# In the container
ls -la /data/dbstore-data/
ls /data/dbstore-data/qldb/ | wc -l
#+END_SRC
Here we use a small sample of an example for open-source
repositories, 23 in all.
* Repository Selection
When using all of the MRVA system, we select a small subset of repositories
available to you in [[*Database Aquisition][Database Aquisition]]. For this demo we include a small
collection -- 23 repositories -- and here we further narrow the selection to 12.
The full list

The selection of 12 repositories, from an initial collection of 6000 was made
using a collection of Python/pandas scripts made for the purpose, the [[https://github.com/hohn/mrvacommander/blob/hohn-0.1.21.2-improve-structure-and-docs/client/qldbtools/README.md#installation][qldbtools]]
package. The resulting selection, in the format expected by the VS Code
extension, follows.
#+BEGIN_SRC text
cat /data/qldbtools/scratch/vscode-selection.json

This selection is deceptively simple. For a full explanation, see [[file:cli-end-to-end-detailed.org::*Repository Selection][Repository
Selection]] in the detailed version of this document.
** Optional: The meaning of the names
The repository names all end with =ctsj= followed by 6 hex digits like
=ctsj4cc9a2=.
The information critial for selection of databases are the columns
1. owner
2. name
3. language
4. "sha"
5. "cliVersion"
6. "creationTime"
There are others that may be useful, but they are not strictly required.
The critical ones deserve more explanation:
1. "sha": The =git= commit SHA of the repository the CodeQL database was
created from. Required to distinguish query results over the evolution of
a code base.
2. "cliVersion": The version of the CodeQL CLI used to create the database.
Required to identify advances/regressions originating from the CodeQL binary.
3. "creationTime": The time the database was created. Required (or at least
very handy) for following the evolution of query results over time.
There is a computed column, CID. The CID column combines
- cliVersion
- creationTime
- language
- sha
into a single 6-character string via hashing. Together with (owner, repo) it
provides a unique index for every DB.
For this document, we simply use a pseudo-random selection of 11 databases via
#+BEGIN_SRC sh
./bin/mc-db-generate-selection -n 11 \
scratch/vscode-selection.json \
scratch/gh-mrva-selection.json \
< scratch/db-info-3.csv
#+END_SRC
Note that these use pseudo-random numbers, so the selection is in fact
deterministic.
* Starting the server
Clone the full repository before continuing:
#+BEGIN_SRC sh
mkdir -p ~/work-gh/mrva/
git clone git@github.com:hohn/mrvacommander.git
#+END_SRC
Make sure Docker is installed and running.
With docker-compose set up and this repository cloned, we just run
#+BEGIN_SRC sh
cd ~/work-gh/mrva/mrvacommander
docker-compose -f docker-compose-demo.yml up -d
#+END_SRC
and wait until the log output no longer changes.
Should look like
#+BEGIN_SRC text
docker-compose -f docker-compose-demo.yml up -d

The content is prepopulated in the =dbstore= container.
** Optional: Inspect the Backing Store
As completely optional step, you can inspect the backing store:
#+BEGIN_SRC sh
docker exec -it dbstore /bin/bash
ls /data/qldb/
# 'BoomingTech$Piccoloctsj6d7177.zip' 'mawww$kakounectsjc54fab.zip'
# 'KhronosGroup$OpenXR-SDKctsj984ee6.zip' 'microsoft$node-native-keymapctsj4cc9a2.zip'
# ...
#+END_SRC
** Optional: Inspect the MinIO DB
Another completely optional step, you can inspect the minio DB contents if you
have the minio cli installed:
#+BEGIN_SRC sh
# Configuration
MINIO_ALIAS="qldbminio"
MINIO_URL="http://localhost:9000"
MINIO_ROOT_USER="user"
MINIO_ROOT_PASSWORD="mmusty8432"
QL_DB_BUCKET_NAME="qldb"
# Check for MinIO client
if ! command -v mc &> /dev/null
then
echo "MinIO client (mc) not found."
fi
# Configure MinIO client
mc alias set $MINIO_ALIAS $MINIO_URL $MINIO_ROOT_USER $MINIO_ROOT_PASSWORD
# Show contents
mc ls qldbminio/qldb
#+END_SRC
* Running the gh-mrva command-line client
The first run uses the test query to verify basic functionality, but it returns
no results.
XX: mrvacommander-client-ghmrva-1
** Run MRVA from command line
1. Install mrva cli
#+BEGIN_SRC sh
mkdir -p ~/work-gh/mrva && cd ~/work-gh/mrva
git clone https://github.com/hohn/gh-mrva.git
cd ~/work-gh/mrva/gh-mrva && git checkout mrvacommander-end-to-end
# Build it
go mod edit -replace="github.com/GitHubSecurityLab/gh-mrva=$HOME/work-gh/mrva/gh-mrva"
go build .
# Sanity check
./gh-mrva -h
#+END_SRC
2. Set up the configuration
#+BEGIN_SRC sh
mkdir -p ~/.config/gh-mrva
cat > ~/.config/gh-mrva/config.yml <<eof
# The following options are supported
# codeql_path: Path to CodeQL distribution (checkout of codeql repo)
# controller: NWO of the MRVA controller to use. Not used here.
# list_file: Path to the JSON file containing the target repos
# XX:

controller: not-used/mirva-controller
list_file: $HOME/work-gh/mrva/gh-mrva/gh-mrva-selection.json

#+END_SRC
3. Submit the mrva job
#+BEGIN_SRC sh
cp ~/work-gh/mrva/mrvacommander/client/qldbtools/scratch/gh-mrva-selection.json \
~/work-gh/mrva/gh-mrva/gh-mrva-selection.json

./gh-mrva submit --language cpp --session mirva-session-1360 \
--list mirva-list \
--query ~/work-gh/mrva/gh-mrva/FlatBuffersFunc.ql
#+END_SRC
4. Check the status
#+BEGIN_SRC sh
cd ~/work-gh/mrva/gh-mrva/
# Check the status
./gh-mrva status --session mirva-session-1360
#+END_SRC
5. Download the sarif files, optionally also get databases. For the current
query / database combination there are zero result hence no downloads.
#+BEGIN_SRC sh
cd ~/work-gh/mrva/gh-mrva/
# Just download the sarif files
./gh-mrva download --session mirva-session-1360 \
--output-dir mirva-session-1360
# Download the sarif files and CodeQL dbs
./gh-mrva download --session mirva-session-1360 \
--download-dbs \
--output-dir mirva-session-1360
#+END_SRC
** Write query that has some results
First, get the list of paths corresponding to the previously selected
databases.
#+BEGIN_SRC sh
cd ~/work-gh/mrva/mrvacommander/client/qldbtools
./bin/mc-rows-from-mrva-list scratch/gh-mrva-selection.json \
scratch/db-info-3.csv > scratch/selection-full-info
csvcut -c path scratch/selection-full-info
#+END_SRC
Use one of these databases to write a query. It need not produce results.
#+BEGIN_SRC sh
cd ~/work-gh/mrva/gh-mrva/
code gh-mrva.code-workspace
#+END_SRC
In this case, the trivial =findPrintf=:
#+BEGIN_SRC java
/**

,* @description find calls to plain fprintf
,* @kind problem
,* @id cpp-fprintf-call
,* @problem.severity warning
,*/
import cpp
from FunctionCall fc
where
fc.getTarget().getName() = "fprintf"
select fc, "call of fprintf"
#+END_SRC
Repeat the submit steps with this query
1. --

6. Use the [[https://marketplace.visualstudio.com/items?itemName=MS-SarifVSCode.sarif-viewer][SARIF Viewer]] plugin in VS Code to open and review the results.
Prepare the source directory so the viewer can be pointed at it
#+BEGIN_SRC sh
cd ~/work-gh/mrva/gh-mrva/mirva-session-1480
unzip -qd BoomingTech_Piccoloctsj6d7177_1_db BoomingTech_Piccoloctsj6d7177_1_db.zip
cd BoomingTech_Piccoloctsj6d7177_1_db/codeql_db/
unzip -qd src src.zip
#+END_SRC
Use the viewer
#+BEGIN_SRC sh
code BoomingTech_Piccoloctsj6d7177_1.sarif
# For lauxlib.c, point the source viewer to
find ~/work-gh/mrva/gh-mrva/mirva-session-1480/BoomingTech_Piccoloctsj6d7177_1_db/codeql_db/src/home/runner/work/bulk-builder/bulk-builder -name lauxlib.c

#+END_SRC
7. (optional) Large result sets are more easily filtered via
dataframes or spreadsheets. Convert the SARIF to CSV if needed; see [[https://github.com/hohn/sarif-cli/][sarif-cli]].
