From d779be08c1fb20febb7dd9a695686be20b68b707 Mon Sep 17 00:00:00 2001 From: Adam Ruka Date: Tue, 6 Jul 2021 12:11:30 -0700 Subject: [PATCH] chore: new private 'cdk-release' tool for performing releases (#15331) Introduce a new repo-private tool called `cdk-release` that replaces `standard-version` in our 'bump' process. It's responsible for updating the version file with the new version, generating the Changelog based on on the commit history, and performing the commit that includes the two above files. It allows us to correctly handle edge cases that we had to work around previously with `standard-version`: * For patch releases, `standard-version` always generated the main header as H3, while we want H2. We always had to correct that manually, and we sometimes forgot. This tool does the correct thing for patch releases too. * We had to hack around when we wanted to change the heading 'BREAKING CHANGES' to 'BREAKING CHANGES TO EXPERIMENTAL FEATURES'. This tool now does it natively, no hacks needed. * In V2, `standard-version` couldn't figure out the tag to compare to, because we have tags for 2 major versions present in the repo. This tool handles this without the hacks of locally removing and then re-fetching the tags. * Also in V2, we want to strip the changes to experimental packages (as those are not included in `aws-cdk-lib`). With `standard-version`, we had to grep in the resulting Changelog, which was very fragile (for example, in `2.0.0-rc.7`, our Changelog includes breaking changes to `appmesh`, which is an experimental module). This tool handles this case natively, by filtering out commits, without the need for fragile Changelog grepping. To make sure we don't break our release process, allow passing the environment variable `LEGACY_BUMP` as truthy to fall back on `standard-version`. Once we make at least one successful release, in both major versions, using this new tool, I'll remove the old `standard-version` based code in a separate PR. In a subsequent PR, the tool will be enhanced with the capability to generate separate version bumps and Changelogs for experimental packages in V2. ---- *By submitting this pull request, I confirm that my contribution is made under the terms of the Apache-2.0 license* --- bump.sh | 6 +- scripts/bump.js | 51 +++-- tools/cdk-release/.eslintrc.js | 3 + tools/cdk-release/.gitignore | 15 ++ tools/cdk-release/.npmignore | 16 ++ tools/cdk-release/LICENSE | 201 ++++++++++++++++++ tools/cdk-release/NOTICE | 2 + tools/cdk-release/README.md | 21 ++ tools/cdk-release/jest.config.js | 10 + tools/cdk-release/lib/conventional-commits.ts | 138 ++++++++++++ tools/cdk-release/lib/defaults.ts | 32 +++ tools/cdk-release/lib/index.ts | 57 +++++ tools/cdk-release/lib/lifecycles/bump.ts | 122 +++++++++++ tools/cdk-release/lib/lifecycles/changelog.ts | 123 +++++++++++ tools/cdk-release/lib/lifecycles/commit.ts | 45 ++++ tools/cdk-release/lib/private/files.ts | 9 + tools/cdk-release/lib/private/print.ts | 23 ++ .../cdk-release/lib/private/run-exec-file.ts | 19 ++ tools/cdk-release/lib/types.ts | 64 ++++++ tools/cdk-release/lib/updaters/index.ts | 59 +++++ tools/cdk-release/lib/updaters/types/json.ts | 28 +++ .../lib/updaters/types/plain-text.ts | 12 ++ tools/cdk-release/package.json | 70 ++++++ tools/cdk-release/test/changelog.test.ts | 110 ++++++++++ tools/cdk-release/tsconfig.json | 21 ++ 25 files changed, 1239 insertions(+), 18 deletions(-) create mode 100644 tools/cdk-release/.eslintrc.js create mode 100644 tools/cdk-release/.gitignore create mode 100644 tools/cdk-release/.npmignore create mode 100644 tools/cdk-release/LICENSE create mode 100644 tools/cdk-release/NOTICE create mode 100644 tools/cdk-release/README.md create mode 100644 tools/cdk-release/jest.config.js create mode 100644 tools/cdk-release/lib/conventional-commits.ts create mode 100644 tools/cdk-release/lib/defaults.ts create mode 100644 tools/cdk-release/lib/index.ts create mode 100644 tools/cdk-release/lib/lifecycles/bump.ts create mode 100644 tools/cdk-release/lib/lifecycles/changelog.ts create mode 100644 tools/cdk-release/lib/lifecycles/commit.ts create mode 100644 tools/cdk-release/lib/private/files.ts create mode 100644 tools/cdk-release/lib/private/print.ts create mode 100644 tools/cdk-release/lib/private/run-exec-file.ts create mode 100644 tools/cdk-release/lib/types.ts create mode 100644 tools/cdk-release/lib/updaters/index.ts create mode 100644 tools/cdk-release/lib/updaters/types/json.ts create mode 100644 tools/cdk-release/lib/updaters/types/plain-text.ts create mode 100644 tools/cdk-release/package.json create mode 100644 tools/cdk-release/test/changelog.test.ts create mode 100644 tools/cdk-release/tsconfig.json diff --git a/bump.sh b/bump.sh index 73954148de7c6..b3c04198b50d3 100755 --- a/bump.sh +++ b/bump.sh @@ -15,5 +15,9 @@ set -euo pipefail scriptdir=$(cd $(dirname $0) && pwd) cd ${scriptdir} -yarn --frozen-lockfile +yarn install --frozen-lockfile +if [[ "${LEGACY_BUMP:-}" == "" ]];
