# releng-scripts
---
This is an AGL job generation tool for [LAVA](https://staging.validation.linaro.org/static/docs/v2/).\
It is written in Python and uses jinja2 templates to generate yaml job files
following the LAVA specifications.
This tool **only** generates jobs. It does not provide a way for submitting jobs to a LAVA server.\
Please refer to the lava-tool [documentation](https://validation.linaro.org/static/docs/v2/lava-tool.html)
for submitting jobs.
## Prerequisites
- Python >= 2.7.1
- jinja >= 2.9
- You can check if a version is/was installed with pip using: ```pip show jinja2```
- If the version is too old, you can update it using: ```sudo pip install --upgrade jinja2```
## Usage instructions
The repo contains several tools that are located in the "./utils" folder.\
Following is a list of the available tools:
- `job-prereq.py` a tool that prints the binary packages needed to create a LAVA jobs
- `create-jobs.py` a tool for generating lava job templates from binary packages hosted on the web
### `job-prereq.py`
Command line tool that prints the packages needed by LAVA to execute a test job.
#### Required arguments:
- `--machine`
- Available machine names: ```{dra7xx-evm,qemux86-64,porter,m3ulcb,raspberrypi3}```
- For an up to date list of machine names run: ```./utils/create-jobs.py --help```
- `--build-type`
- Needs three arguments formatted as follow: `{build-type-name,branch,version}`.
- the build `build-type-name` must be one of: ci, daily, weekly, release.
- the build `branch` or `changeid` must be a branch name or changeid number.
- the build `version` or `patchset` must be the version or patchset number.
#### Optionnal arguments
- `--dtb`
- prints to stdout the needed `dtb` package name to create this specific LAVA job definition.
- `--kernel`
- prints to stdout the needed `kernel` package name to create this specific LAVA job definition.
- `--initrd`
- prints to stdout the needed `ramdisk` package name to create this specific LAVA job definition.
- `--nbdroot`
- prints to stdout the needed `root file system` package name to create this specific LAVA job definition.
Exception: if the machine is `qemux86-64` only `--kernel` and `--initrd` optionnal arguments are available. As qemu LAVA jobs do not need a `dtb` or `nbdroot`.
_Examples:_
```bash
./utils/job-prereq.py --machine qemux86-64 --build-type {ci,11524,2} --kernel --initrd
./utils/job-prereq.py --machine raspberrypi3 --build-type {release,eel,v4.9.3} --kernel --initrd --nbdroot --dtb
./utils/job-prereq.py --machine m3ulcb --build-type {daily,eel,v4.9.3} --kernel --dtb
./utils/job-prereq.py --machine dra7xx-evm --build-type {ci,11524,2} --initrd --nbdroot
./utils/job-prereq.py --machine porter --build-type {ci,11524,2} --kernel --initrd --nbdroot --dtb
```
### `create-jobs.py`
Command line tool to generate AGL jobs for LAVA.
##### Required arguments:
- ```./utils/create-jobs.py --machine machine-name```
- Available machine names: ```{dra7xx-evm,qemux86-64,porter,m3ulcb,raspberrypi3}```
- For an up to date list of machine names run: ```./utils/create-jobs.py --help```
##### Artifacts fetching from URL:
Amongst other things, this tool is used to generate URLs for fetching build artifacts from specific locations.\
The default location is: https://download.automotivelinux.org/AGL/\
The default build is dab version 4.0.2
The user can override these defaults using the command line:
- ```--url <release, daily, ci or http://my-custom-url....>```
- Available url options and their corresponding URL:
- release: https://download.automotivelinux.org/AGL/release/
- daily: https://download.automotivelinux.org/AGL/snapshots/
- ci: https://download.automotivelinux.org/AGL/upload/ci/
If using the url argument the user has to specify other arguments depending on the url:
- release: ```--branch and --version```
- daily: ```--branch and --version```
- ci: ```--changeid and --patchset```
If using a custom url these argument are not used and should not be set. The tool will suppose that the custom url points directly to build artifacts for the target machine.
_Examples:_
```bash
./utils/create-jobs.py --machine m3ulcb
./utils/create-jobs.py --machine qemux86-64
./utils/create-jobs.py --url release --branch eel --version 4.99.1 --machine m3ulcb
./utils/create-jobs.py --url release --branch eel --version 4.99.1 --machine qemux86-64
./utils/create-jobs.py --url daily --branch master --version latest --machine m3ulcb
./utils/create-jobs.py --url daily --branch master --version latest --machine raspberrypi3
./utils/create-jobs.py --url ci --changeid 11533 --patchset 2 --machine raspberrypi3
./utils/create-jobs.py --url ci --changeid 11533 --patchset 2 --machine m3ulcb
./utils/create-jobs.py --url http://baylibre.com/pub/agl/ci/raspberrypi3 --machine raspberrypi3
```
The full list of arguments with default values is available using the helper:\
`$ ./utils/create-jobs.py --help`
##### Add tests to a job
To add tests to a job description please refer to the specific documentation: [releng-scripts-folder]/doc/test-documentation.md
