## hledger release types

hledger major releases happen each quarter, normally at the start of the third month (see [past releases](relnotes.md)).
Bugfix releases follow those when needed, usually soon after.
Preview/nightly releases may happen any time.

After release, it's a good time for:

  - finance repo updates
  - hledger.org doc updates
  - pta.o doc updates

## How to..

More procedure notes.

### Check release readiness

- Any blocking open issues ? <https://bugs.hledger.org>
- Any blocking open PRs ? <https://prs.hledger.org>
- Any blocking items on <https://hledger.org/ROADMAP.html> ?
- Any blocking items in personal notes & backlogs ?

### Check tools are up to date
- Check for consistent stackage snapshot(s) and extra deps used in
  stack.yaml, Shake.hs, hledger-install.sh, bin scripts, tools scripts
- Shake binary is up to date
  `./Shake.hs`
- `hpack --version` matches the one in `stack --version`

### Run local tests
- `just test`
- `just doctest`
- `just haddocktest`

### Run CI tests
- push to a PR, wait for green
- or push to `ci` branch, wait for green at <https://ci.hledger.org>
- or `just push` (pushes to `ci`, then to `master`)

### Run release branch tests
- `just test`
- `stack exec -- hledger --version`, check version, hash, release date, no '+'
- `stack exec -- hledger help | tail`, check version, month matches release

### Update the Install page
In site repo:
- update `install.md`
  - query-replace OLD -> NEW in 
    - "current hledger release"
    - CI binaries badges/links, including linux-static-arm32v7 if built
    - "building from source"
    - stack install command
    - cabal install command
  - query-replace OLD-brightgreen -> OLD-red
  - only after release binaries are built (preferably after release is published):
    update --version outputs (version, hash, date, but not platform)
  - final output line from `hledger test` (run local build and in terminal for normal speed)
  - Total count from `make functest`
  - preview
  - commit: `install: NEW`

### Update hledger in stackage

- monitor packaging status in lts and nightly: <https://www.stackage.org/package/hledger>
- update <https://github.com/fpco/stackage/blob/master/build-constraints.yaml> as needed

### Update RELEASING.png
- edit RELEASING.canvas in obsidian
- CMD-p > Export as image, don't show logo
- commit

## Tips

- Release, or practice releasing, often to improve the process.

- Use and continually update RELEASING.md.
  Document procedures and gotchas to save time and enable automation in future.

- Also the diagram (RELEASING.canvas, made with Obsidian).

- But don't document prematurely or in too much detail.

- Make things a little better each time through: simpler, more reliable, better documented, more automated, easier, faster, cheaper, higher quality.

- Optionally save this file as RELEASING2.md and update notes there until after release, if it's interfering with git branch switching.

- Use and update scripts, in `Justfile`, `Shake.hs`, `tools/` etc.

- Do all releases from a release branch.

- Update dev changelogs frequently in master. Finalise changelogs in the release branch. Merge back to master after release.
  (Related older doc: [CHANGELOGS](CHANGELOGS.md))

- All release binaries should be built from the release-tagged commit.
  The binaries' --version output should match the release tag and release date.

- Try to do only full releases including all four main hledger packages; partial releases add complexity.

- Try to avoid pre-announcing a hard release date. 
  It will always take more time than you think,
  if you go late you might miss your intended date in many timezones,
  and there's no point adding unnecessary pressure.

- The biggest potential time sinks are:

  - reviewing/relearning the process/docs/infrastructure
  - updating/improving the process/docs/infrastructure
  - preparing changelogs
  - building binaries for all platforms
  - troubleshooting github workflow issues
  - followup work due to release mistakes, bugs in new features, or regressions

- Hard/risky/intensive tasks should happen without time pressure;
  during the final countdown, things should be easy.

## Release manager activities

These have complex interdependencies and sequencing constraints.
Chunk, separate, routinise, document and automate them as far as possible.

## Glossary

Some standard terminology, useful when precision is needed, eg in release scripts.

### General

**release**\
A snapshot of the software and related artifacts like executable binaries, which is named, tagged, documented, announced, and usually picked up by packaging systems on various platforms.

**version control system, VCS**\
A tool used for storing and sharing and viewing the history and different lines of development of a software project, or other set of files. hledger uses Git.

**repository, repo**\
A set of files being stored and managed by a VCS. Often published on a **repository hosting service**, such as Github.

**working copy, clone**\
A local copy of a repository's files. Typically each developer has one or more of these, and can share changes easily with the official public repository.

**branch**\
Some VCS's, including Git, can store multiple branching lines of development within one repository. A working copy can be quickly switched to a different branch to show its content.

**master, main**\
The main branch in a repo, usually named `master` or `main`. Pull requests are usually relative to this.

**pull request, PR**\
A request to merge a development branch with master, and any related discussion. On Github, these are kept alongside issues in the issue tracker.

**continuous integration, CI**\
Automated actions that run when new code is pushed to a shared repo, such as running tests or producing binaries. On Github this is called Github Actions and action scripts are called **workflows**.

**release engineering**\
<https://en.wikipedia.org/wiki/Release_engineering>

### hledger-specific

**package**\
A releasable unit of Haskell software. hledger has several core packages usually released together: hledger-lib, hledger, hledger-ui, hledger-web.

**hledger version number**\
A 2-4 part dotted number naming a hledger release or hledger package version: `MA.JOR[.MINOR[.FIXUP]]` or `MA.JOR.99[.PREVIEW]` where 99 means "unreleased (MAJOR+1)". See examples below.

**hledger version string**\
A line of text describing a hledger binary, shown by `--version`. It contains program name, version number, commit hash and date, machine architecture etc. Eg: `hledger 1.24.1-g7799d526b-20211210, mac-x86_64`

**Full release**\
A release of all four core hledger packages (hledger-lib, hledger, hledger-ui, hledger-web). Major and preview releases are always full releases.

**Partial release**\
A release of just some of the hledger packages. Bugfix and fixup releases are sometimes partial.

**Single-version release**\
A release where all packages have the same version. Major and preview releases are always single-version.

**Mixed-version release**\
A release where the packages have different versions, because of a previous partial release. Bugfix and fixup releases are sometimes mixed-version.

**changelog**\
A CHANGES.md file listing the release history and the changes in each release. There is one for each hledger package and one for the hledger project as a whole.

**release notes**\
The Release Notes page on the hledger website: the combined release history of the core hledger packages, showing user visible changes only.

### Releases and builds

**Major release**\
Major releases include new features and incompatible API changes, and normally happen at the start of each quarter's third month (3/1, 6/1, 9/1, 12/1). Example version number: `1.25`

**Bugfix release**\
Bugfix releases include only bug fixes, without API changes. These happen when needed, to fix significant bugs in the previous major release. Example version number: `1.25.2` (**"second bugfix release for 1.25"**)

**Fixup release**\
Fixup releases fix packaging errors, with no changes to the hledger software. Example version number: `1.25.0.1` or `1.25.2.1` (**"first fixup release for 1.25 / 1.25.2"**).
These should rare; we basically never do these.

**Preview release**\
A preview of the upcoming major release for testers/early adopters, and a test of the release process, published on Github. Not a formal hledger release, eg not published on Hackage, usually not packaged, no bugfix releases, no regression bounties, not shown in release notes. These typically appear in the quarter's first and second month if needed. Example version number: `1.25.99.1` (**"preview 1 of 1.26"**)

**CI binaries**\
Temporary downloadable binaries produced by a run of the `linux`/`mac`/`windows` workflows in the hledger repo. This may happen periodically, eg weekly. Downloading requires a Github login.

**Dev build**\
A local developer build of unreleased code. This is typically in `master` or a development/PR branch. Example version number: `1.25.99` (**"unreleased 1.26-dev"**)

### Repos and branches

**hledger repo**\
The `hledger` git repository, containing the hledger software, reference manuals, and developer docs. <https://github.com/simonmichael/hledger>

**site repo**\
The `hledger_website` git repository, containing most of the hledger website which appears at <https://hledger.org>. Usually checked out under the hledger repo as `site/`. <https://github.com/simonmichael/hledger_website>

**finance repo**\
The `hledger_finance` git repository, containing the hledger project's financial ledger. Usually checked out under the hledger repo as `finance/`. <https://github.com/simonmichael/hledger_finance>

**master**\
The branch named `master` in the hledger repo; the main line of hledger development. Pull requests are usually relative to this.

**release&nbsp;branch**\
Branches named `MA.JOR-branch` in the hledger repo, eg `1.25-branch`. Releases and release previews are always made from a release branch.
