gg_multi_maintain

English | Deutsch

Runs maintenance tasks like SDK, DNA and dependency upgrades in all ocean repos in parallel and publishes every changed repo.

Motivation

A gg workspace holds a hundred repos in its ocean. Raising the Dart SDK, pulling in a new DNA layer or upgrading the dependencies used to mean a ticket per repo, or one huge ticket whose dependency hull dragged every repo in. gg do maintain does such routine work for the whole ocean in one call:

• every repo gets its own fresh clone and branch, the ocean stays as it is
• the repos run in parallel, but a repo waits for the repos it depends on, so an upgrade sees the versions the same run just released
• every changed repo is committed and published on its own with gg one do publish, with all checks and tests of gg one do commit
• a failing repo only stops the repos that depend on it

Installation

gg do maintain comes with gg:

dart pub global activate gg

Usage

Run it at the root of a gg workspace and choose at least one task:

gg do maintain --upgrade-sdk                 # Dart SDK and Node constraints
gg do maintain --upgrade-dna                 # the DNA layers, then regenerate
gg do maintain --upgrade-deps                # compatible dependency upgrades
gg do maintain --upgrade-deps --major        # also across major versions
gg do maintain --all --org ggsuite --dry-run # see what would change

Option	Meaning
--upgrade-sdk	Raises environment: sdk: to the installed Dart and engines.node to the installed Node
--upgrade-deps	Upgrades the dependencies to the newest compatible versions
--major	With --upgrade-deps: allows major version jumps
--upgrade-dna	Upgrades the DNA layers and the helix engine, then regenerates the DNA
--all	All tasks above
-j, --jobs	How many repos run at the same time, default 4
--org, --repo	Limit the run, e.g. --org tssuite or --repo 'gg_*'
--version-increment	patch, minor or major for every repo
--no-pana	Skip pana before publishing Dart packages
-n, --dry-run	Apply the tasks and report the changes, without commit and publish

The example prints the help of the command:

import 'package:args/command_runner.dart' show CommandRunner;
import 'package:gg_multi_maintain/gg_multi_maintain.dart';

Future<void> main() async {
  final runner = CommandRunner<void>('gg', 'Maintains the ocean.')
    ..addCommand(DoMaintain(ggLog: print));
  await runner.run(['help', 'maintain']);
}

At the end, the command prints a summary like this:

Published (2):
  ggsuite/gg_hash: 3.1.5
  ggsuite/gg_json: 2.4.1
Unchanged (1):
  ggsuite/gg_log
Skipped (1):
  ggsuite/testproject_gg_1: a test project

Limitations

• Test projects, private packages and repos without a remote are skipped. A package that was never published is skipped too, because its first version is published by hand.
• npm publishes may ask for a one-time password, so they run one at a time. pnpm's minimum release age can hold back a version that the same run has just published.
• Only lock files or gg's state in .gg/ changed? Then the repo counts as unchanged and is not published.

How it works

Each run gets a folder <workspace>/.maintain/<run id>/<org>/<repo>. The pipeline of a repo is: clone, skip it if it was never published, create the branch maintain_<run id>, install, run the tasks, detect the changes, gg one do commit, gg one do publish, delete the clone. The version increment is minor when a regular dependency jumps across its old constraint, otherwise patch. A failed clone stays in the run folder with its log.

Status

Before 1.0 — the options may change between minor versions.
