1. All github events go in to web/index.php, which sends the event to
|
|
an exchange named for the full name of the repo (ex: nixos/nixpkgs)
|
|
in lower case. The exchange is set to "fanout"
|
|
2. build-filter.php creates a queue called build-inputs and binds it
|
|
to the nixos/nixpkgs exchange. It also creates an exchange,
|
|
build-jobs, set to fan out. It listens for messages on the
|
|
build-inputs queue. Issue comments from authorized users on
|
|
PRs get tokenized and turned in to build instructions. These jobs
|
|
are then written to the build-jobs exchange.
|
|
3. builder.php creates a queue called `build-inputs-x86_64-linux`, and
|
|
binds it to the build-jobs exchange. It then listens for build
|
|
instructions on the `build-inputs-x86_64-linux` queue. For each
|
|
job, it uses nix-build to run the build instructions. The status
|
|
result (pass/fail) and the last ten lines of output are then placed
|
|
in to the `build-results` queue.
|
|
4. poster.php declares the build-results queue, and listens for
|
|
messages on it. It posts the build status and text output on the PR
|
|
the build is from.

## Getting Started
|
|
|
|
- you'll need to create the `WORKING_DIR`
|
|
- nix-shell
|
|
- composer install
|
|
- php builder.php
|
|
|
|
The conspicuously missing config.php looks like:
|
|
|
|
|
|
|
|
```php
|
|
<?php
|
|
|
|
require_once __DIR__ . '/vendor/autoload.php';
|
|
use PhpAmqpLib\Connection\AMQPSSLConnection;
|
|
use PhpAmqpLib\Message\AMQPMessage;
|
|
|
|
define("NIX_SYSTEM", "x86_64-linux");
|
|
define("WORKING_DIR", "/home/grahamc/.nix-test");
|
|
|
|
function rabbitmq_conn() {
|
|
$connection = new AMQPSSLConnection(
|
|
'events.nix.gsc.io', 5671,
|
|
eventsuser, eventspasswordd, '/', array(
|
|
'verify_peer' => true,
|
|
'verify_peer_name' => true,
|
|
'peer_name' => 'events.nix.gsc.io',
|
|
'verify_depth' => 10,
|
|
'ca_file' => '/etc/ssl/certs/ca-certificates.crt'
|
|
)
|
|
);
|
|
|
|
return $connection;
|
|
}
|
|
|
|
/*
|
|
# Only leader machines (ie: graham's) need this:
|
|
function gh_client() {
|
|
$client = new \Github\Client();
|
|
$client->authenticate('githubusername',
|
|
'githubpassword',
|
|
Github\Client::AUTH_HTTP_PASSWORD);
|
|
|
|
return $client;
|
|
}
|
|
*/
|
|
```
|
|
|
|
|
|
## Getting started on the rust one...
|
|
|
|
```
|
|
cargo build
|
|
```
|
|
|
|
then copy config.example.json to config.json and edit its vars. Set
|
|
`nix.remote` to an empty string if you're not using the daemon.
|
|
|
|
Run
|
|
|
|
```
|
|
./target/debug/builder ./config.json
|
|
```
|
