Guardrails / php

Composer requirements are constrained ​

php/dependencies-constrained@v1

Every package the manifest requires has a version constraint, instead of accepting whatever the registry serves.

Collectors ​

This guardrail doesn't gather anything itself. It relies on the collectors below, which the CLI runs once per build before any check, and reads what they found from GUARDRAIL_FACTS. If a collector collects nothing, this guardrail is skipped, not failed.

CollectorGathersInputs it is given
phpThe Composer project in the project directory: the package it declares, the PHP version and extensions it asks for, the packages it requires and which of them are pinned, and whether the lock file is committed.projectDir

The inputs above are this guardrail's own inputs, passed straight through to the collector. Setting one in buildnote.json changes what is collected, and two guardrails configured the same way share a single collection.

Configuration ​

json
{
  "guardrails": {
      "failOn": "error",
      "checks": [
          {
              "use": "php/dependencies-constrained@v1",
              "severity": "warning",
              "with": {
                  "projectDir": "."
              },
              "exemptions": []
          }
      ]
  }
}

How to fix ​

Give every requirement a constraint naming the major release it was written against:

json
{
  "require": {
    "symfony/console": "^7.0"
  }
}

A * requirement takes whatever the registry serves, including the next major release, so an upstream release can change what this project installs without any change in this repository.

More in php ​

  • php/lockfile-committed. The project commits composer.lock, so an install of the same commit resolves the same versions.
  • php/version-declared. The project declares the PHP version Composer resolves against, and that version is no older than the configured floor.
