Add floating version tag actions and the release workflow that uses them - #3

Conversation
House rule 2 has consumers pin `@v1`, so a published release has to move v<major> and v<major>.<minor> onto the released commit. Nothing did that yet. The flow is adapted from the tag half of stellarwp/changelogger's publish.yml. Its other half does not apply here: there is no build output to commit, so the release tag already names the commit consumers should get. Four things work differently from the version it was taken from. It writes the minor tag as well as the major, which is what lets a repo pin a line rather than only a major. A floating tag moves only when the release being published is the newest one that tag covers. Moving it unconditionally points v1 at older code as soon as a patch lands on an older line: publishing 1.2.4 after 1.3.0 is out. Each tag is compared only against releases in its own line, so a newer major does not hold a lower one back, and someone pinned to @v1 still receives a backported patch. Prereleases are skipped on two separate signals, because either can occur alone. A suffixed tag such as 1.3.0-rc.1 fails the X.Y.Z pattern on its own. A plain 1.3.0 marked as a prerelease on GitHub does not, so the release event's prerelease flag is passed in as an input. A tag ref's existence is checked before it is written, rather than trying a PATCH and falling back to a POST on failure. A PATCH also fails for a token without permission or for a protected tag, and the fallback would report those as a successful creation. The check uses git/ref (singular), which 404s on a missing ref. The plural git/refs/tags/v1 matches by prefix, so it answers 200 whenever a v1.0.0 tag exists even with no v1 to update. Split across two actions so either half can be used alone. resolve-floating-tags works out which tags a version should own and writes nothing; move-git-tags writes any tag names it is handed and knows nothing about versions, so it also moves a stable or latest pointer. Release tags are accepted as 1.2.3 or v1.2.3, since the brands being merged here do not agree on the prefix. The floating tags always carry the v, because that is what a `uses:` line resolves.

Four changes to how a release resolves its floating tags. The require-newest input is gone and the check it governed always runs. It was never optional in practice: v1 means the newest 1.x, so pointing it at an older release is wrong whether or not a caller asked for the check. Publishing 1.1.1 while v1 points at 1.2.0 now moves v1.1 and leaves v1 alone. Dropping the flag also drops the caveat about repos that publish no Releases, which the existing fallback already covers. The is-prerelease input is gone too. The release list this action already reads carries isPrerelease, so the flag comes from there rather than from the caller, and it no longer depends on what triggered the workflow. allow-prereleases replaces it, off by default. It lets a prerelease own a floating tag whose line has had no stable release yet, and nothing more. Publishing 1.4.0-rc.1 while 1.3.0 is the newest stable release resolves v1.4 and leaves v1 on 1.3.0, so @v1.4 is how someone opts into testing the line before it ships while @v1 keeps handing everyone else a released version. Each rc replaces the one before it on v1.4, and 1.4.0 then takes the tag off the last rc. Once 1.4.0 has shipped, no later 1.4 prerelease can take either tag. Only stable releases are counted when finding the newest release of a line. That is what lets one rc replace another, and it keeps an outstanding rc from holding a stable release back. Prereleases of one version are not ordered against each other, so republishing an earlier rc moves the minor tag back to it; ordering them would mean comparing prerelease identifiers by semver precedence, which sort -V does not do. Build metadata is no longer read as a prerelease. Only a `-` suffix is one, so 1.4.0+build.7 is a stable 1.4.0 and owns what a stable 1.4.0 owns. The release list is normalised the same way the released tag is, so a release carrying metadata or a suffix compares as its own version instead of being invisible to the comparison and losing to an older release. A fourth version part is read as another release of the same minor line rather than a line of its own, which is what a hotfix is. Publishing 1.2.3.1 moves v1.2 because it is the newest release of the 1.2 line, and re-publishing 1.2.3 afterwards moves nothing. A repo that adds a fourth part only when a hotfix exists needs no configuration for it, and there is no third floating tag: a v1.2.3 tag would collide with the release tag of the same name on a v-prefixed repo.
Sentences telling the reader how to regard a fact, rather than stating it: "That is the case to know about", "That is what makes the flag useful rather than dangerous", "This is also what makes publishing out of order safe", "is the whole test". Also two idioms, "swallowed the error" and "takes the tag off". The no-Releases section keeps its own heading. The release list decides the line comparison for stable releases too, not only prereleases, and a repo without it loses the comparison outright: a floating tag there follows whatever was published most recently rather than whatever is newest.

`gh release list` is ordered by publication date and capped by --limit. On a repo with more releases than the cap, a high version published long ago sits past the end of the list. The comparison then found nothing newer than the release being published and moved the tag backwards onto it: with 300 releases and a 1.5.0 old enough to fall past a 200 cap, publishing 1.2.5 moved v1 from 1.5.0 to 1.2.5, and said nothing about it. Raising the limit moves the cliff rather than removing it, so the version lines now come from the repository's tags through matching-refs with --paginate, which has no cap. Tags also exclude drafts without asking, since a draft release has no tag, and each name is normalised the way the tag input is so a tag carrying build metadata compares as its own version. The Releases API is still needed for one thing, whether the release being published is marked as a prerelease, and that is now asked with `gh release view` on that one tag instead of by listing releases. A consequence: a tag whose name is a plain version counts as a released version even when the release behind it is marked as a prerelease, since tag names do not carry the flag. A suffixed tag never counts. This decides only which version is the newest of a line, and it errs toward leaving a floating tag where it is. The release being published is exempt, because its own tag would otherwise be the released version that blocks it: a 1.3.0 marked as a prerelease resolves v1.3 and leaves v1, rather than resolving nothing. Also name the `tag` input where the docs said "this release", which did not say which release was meant.

The two actions were one long bash script each, nested inside YAML. Reading them meant reading through sed, awk and grep pipelines, and testing them meant extracting the script out of the manifest and putting a fake `gh` on PATH. actions/github-script supplies a Node runtime and an Octokit already authenticated with the token input, so resolve.js and move.js run as they are. Nothing is installed and nothing is built: nodeNN actions need a committed dist/, github-script does not. The scripts are loaded by path rather than inlined, because github-script's require resolves against the workspace of the repository being built rather than the action's own directory; the path comes from github.action_path. Inputs arrive through process.env rather than being interpolated into the script, so a tag name is data and cannot become part of the program. This fixes a bug the bash carried. Publishing 1.4.0-rc.1 after a released 1.4.0 resolved v1.4 and moved it off the release. The exclusion that keeps a release from blocking itself matched on the core version, so it removed the released 1.4.0 rather than only the tag being published. It now matches the published tag's own name, and the released 1.4.0 blocks the rc as it should. Two more things fall out of Octokit. A failed write is told apart by status, so only a 404 from the existence check means "does not exist" and a 403 from a protected tag fails the job instead of being retried as a creation. And the version line test is now a part-by-part comparison rather than an anchored regex, which is what kept 122.3.4 out of the 1.2 line. Both scripts export their pure functions, so tests/ covers every rule in the two READMEs with no API and no shell: 28 cases over the line comparison, hotfix versions, prereleases, build metadata, level handling, rejected tags, tag name validation and the degraded paths. tests/ mirrors the action layout, so tests/actions/<action>/<script>.test.js sits opposite .github/actions/<action>/<script>.js. Adds a Tests workflow to run them, which is this repo's first check of its own.
The Tests workflow failed on its first run: `node --test tests/` resolved `tests` as a module to load rather than a directory to search, on the Node 24.21 the runner ships. Node 26 expands it, which is why it passed locally. Bare `node --test` finds every *.test.js under the repository on both, and involves no path or glob semantics that change between versions.

A repo that commits build output at release time does not know the commit its tags should point at until the build has run. The two actions already support that, and it is a better reason for the split than either half being usable alone: resolve-floating-tags reads only tag names and the release, so it can run before the build, and move-git-tags takes the commit as an input. Which tags are resolved does not depend on where the build lands. A build commit changes what a tag points at, not what it is called. The release tag can be moved in the same move-git-tags call as the floating tags, since it is just another name to it, and moving it through the API rather than by force-pushing keeps the Release attached. Notes the constraint that catches this out: a ref can only name an object the remote already has, so the build commit has to be pushed before any tag can point at it.
"A floating tag is repointed on every release" overstated it. A tag moves only when the resolver claims it, which the rest of the README is about.
The actions run at the released commit rather than the version on the default branch, and that was not written down. A release event reads this workflow from the released commit too, so the workflow and the actions it calls are always the same revision.

A run printed 29 sibling lines, so the output did not say which action or which function each case belonged to. They are now nested by action, then by function or behaviour, and several compound cases are split so each name states one fact. Coverage is unchanged; the split brings the count to 52.
"An Octokit stand-in" did not say where the object comes from or why it exists. Both fakes replace an argument actions/github-script passes to the script, so the docs now name that argument, say which methods are implemented, and say what the real one does instead: write to GITHUB_OUTPUT, and send requests.
The fakes recorded a formatted string per call, which dropped the owner and repo. Pointing every write at a wrong owner left all 52 tests passing, so the thing the actions mostly do, send requests, was not being checked. The tests now build the real clients that actions/github-script passes to a script, and replace only the network. `github` is an Octokit from @actions/github given a fetch that answers from a list of rules and records every request, so an assertion is the request the action would have sent. `core` is the real @actions/core writing to a GITHUB_OUTPUT file in a temporary directory, so outputs are read back the way a later step would see them. Nothing is faked above the network. That catches what the fakes could not. The wrong owner now fails six tests, and dropping `force` from an update fails one. It also pins behaviour the manifests only describe: the existence check goes to git/ref, the single-ref endpoint, and not to the prefix-matching one; `force` travels in the body; `createRef` takes a full refs/tags/ name where `getRef` and `updateRef` take tags/. resolve.js's run() had no tests at all, since only its pure function was reachable without an API. It is now covered, including following pagination to a later page, reading the prerelease flag for the tag it was given, a tag with no release behind it, and a failed tag read. Writing the rules found the same bug in the harness that move-git-tags guards against in production: a substring match let the rule for tags%2Fv1 answer the request for tags%2Fv1.2, so a missing tag looked like it existed. Rule paths are exact strings or explicit regular expressions now. Both packages are ESM only, so the support module loads them with dynamic import and its factories are async. bun installs them, and no lockfile is committed: nothing built is versioned here, so each run resolves the newest versions the ranges allow, which is what a consuming repo would get. The actions themselves still install nothing, because github-script supplies both at runtime.
Driving the real @actions/core meant its log reached the runner. info wrote lines between the test suites, and notice and warning wrote the ::notice:: and ::warning:: commands the runner turns into annotations, so a passing run put a warning and two notices on its own job: warning: Could not read stellarwp/plugin-toolbox's tags (Forbidden). ... notice: Resolved no floating tags: 1.3.0 is a prerelease. ... notice: v1 stays where it is: 1.9.0 is newer than 1.2.0. The support module now collects what core writes to stdout and restores stdout when the test ends, through the test context, which the runner runs before it reports the result. Capturing rather than silencing means the messages can be read, and the two the actions are relied on to emit are asserted now: the notice that names a prerelease as the reason nothing resolved, and the warning that the tags could not be read. Both arguments now come from one actionsFor(t, rules) call, since every test that needs one needs the other.
Several blocks named what a function did and stopped there, so the arguments and the return value were undocumented: jsonResponse and readOutputs in the test support module, toVersion, compareVersions, isInLine, readTagNames and readPrereleaseFlag in resolve.js, and the test helpers rulesFor, sequence, tagPage, repoWith and resolve. toParts and both run functions had no block at all. Every function now documents its parameters, its return value and what it throws. A few also say why they are shaped as they are, where that was only in my head: readOutputs parses the heredoc format core writes so the assertion is what a later step would read, and readPrereleaseFlag reads a 404 as not a prerelease so a repository that pushes tags without publishing Releases still resolves.
A block ran the description, the parameters and the outcome together, so the parameter list and what comes back read as one paragraph. Each group now has a blank line before it. @throws moves above @returns. JSDoc fixes no order, and what a call can fail with is worth reading before what it hands back when it does not. Also describes the one @returns that carried a type and nothing else, resolveFloatingTags, whose shape is the least obvious of them.
The order put configuration in the middle of the data: tag, levels, allowPrereleases, tagNames, flaggedPrerelease. The call site read as a list with no shape, and said nothing about which of them are facts and which are settings. They are now the release being resolved and what GitHub says about it, then the tags it is compared against, then the two a caller tunes. tag and tagNames also sit next to each other, which is where the similar names are easiest to tell apart. Destructuring ignores key order, so nothing behaved differently, but five test call sites listed their keys in the old order and now follow the signature.
It ran to 110 lines doing five things: reading the three forms of the release tag, validating the levels input, deciding whether the release is a prerelease, building the set of released versions to compare against, and deciding each tag. The rule for any one of them was only findable by reading all of it. Each is its own function now, and resolveFloatingTags is the 20 lines that put them in order. readReleaseTag returns either the forms or a reason the tag owns nothing, so the two ways a tag can be rejected live with the parsing rather than with the orchestration. decideTag answers for one tag, which is what makes the loop three lines. staysPut carries the shape of a decision not to move, which the two cases were each spelling out in seven lines. No behaviour changes: the same 61 tests pass, including the order the inputs are checked in, which a reordering here would have broken.
compareVersions, isInLine and toVersion already had their own cases, so the five functions the split produced have them too: readReleaseTag, readLevels, releasedVersions, decideTag and staysPut, plus toParts, which was never exported. Mutating each rule showed one the suite could not see: comparing the newest release with `>=` instead of `>` broke nothing. It is reachable, because compareVersions reads 1.2.3 and 1.2.3.0 as one version, so a repository that writes a fourth part on its base releases would have had the tag held back by a release that is not newer. decideTag now has that case, and it fails under the mutation. Reversing the level order, loosening isInLine and dropping the self-exclusion from releasedVersions each failed tests already.
Seven blocks were named after a behaviour rather than a function, so they sat beside the per-function blocks as though they tested something else. They all exercise resolveFloatingTags, and are nested under it now. Every block in the file is a function again, with the categories one level in: each tag is decided on its own line, hotfix versions, the versions it accepts, levels, prereleases, unreadable tags, and the version output.
readLevels checks which names are levels, the order they come back in, a repeat and both failures, so the five cases under resolveFloatingTags that went over the same ground are down to two: that the levels are acted on, and that a bad one fails the call rather than quietly resolving fewer tags. readReleaseTag checks which versions are rejected and with what reason, so what is left there is one case for a rejection becoming an empty result with the reason logged. One of the dropped cases was passing for the wrong reason. It asserted that `1.2.3-` resolves nothing, reading that as "not a numeric version". It is not: the dash is what marks a prerelease, so the core is 1.2.3 and the tag is read as a prerelease, which also resolves nothing by default. Asserting only the flattened output hid the difference. readReleaseTag now pins what it actually does. Mutating readLevels' order, decideTag's comparison, the depths it loops over and the rejection branch still fails tests, so the trims cost no coverage.
The resolve() helper took the same argument the function takes and returned a subset of what it returns, so all it did was hide the version and the notices. Each case now calls resolveFloatingTags and destructures the lists it is about, which also lets the rejection case read the version and the notice it logs. Two cases were asserting twice because the helper made an assertion a single line. They are separate cases now: a v-prefixed tag reading the same as a bare one, and each level resolving only its own tag. The pipe format the helper invented is gone with it. `'v1.2 | v1'` did not say which side was which, and flattening the result is what let an earlier case pass for the wrong reason.
readReleaseTag's docs said what each form drops but not why there are three, so
there was no way to tell releaseVersion and core apart beyond the suffix, or to
know which to reach for. Each is now described by its job, worked through
v1.4.0-rc.1+build.7:
version 1.4.0-rc.1+build.7 what the release is called, so what the
notices name and the action reports
releaseVersion 1.4.0-rc.1 how the tag reads once the tag list is
normalised, so what excludes the release
from its own comparison
core 1.4.0 what versions are compared by, and what
the tag names are built from
Which also says why comparing the two shorter forms is the prerelease test: they
differ by the suffix and nothing else.
A tag carrying both metadata and a suffix was not tested, though it is the only
shape where all three forms differ. It is the worked example, so it is now the
test too.

The actions are meant to be called from other repos, and neither README said whose token the default is. `github.token` is the token of the workflow that runs the action, scoped to that repository, so a calling repo reads and writes its own tags with its own token and needs no secret. move-git-tags now also records the one consequence of that default: GitHub creates no workflow run for an event made with GITHUB_TOKEN, apart from workflow_dispatch and repository_dispatch, so a repo with a workflow on `push:` for `tags:` will not see a tag this action moved. That needs a PAT or app token. resolve-floating-tags had no permissions section at all. It needs contents: read, which a workflow has unless it sets permissions to none.
A 0.x release resolves v0 and v0.1 like any other, which the README did not say. Semver puts breaking changes in the minor below 1.0.0, so v0 can break where v1 cannot. This repo offers it regardless: v0 tracks the newest 0.x, and pinning it accepts that. A repo that would rather not offer it sets levels: minor, which resolves v0.1 and no v0.
"offers it anyway", "would rather not" and "can break you" were attitude and second person rather than statement. The section now says what a 0.x release resolves, what semver puts in the minor below 1.0.0, that this repo writes v0 regardless, and what levels: minor does instead.
"This repo writes v0 regardless" was ambiguous in an action README: the repo reading it is the one calling the action, not this one. It now names the repo publishing the release and the workflow pinning its tag, with the uses: line that moves. The order is the semver rule, then levels: minor as the way out, then what keeping the default means for anyone pinning v0.
release-tags.yml is a file to copy. House rule 1 asks for a uses: instead, which needs a workflow_call wrapper, and the reusable workflow layer is Phase 3 work. Records the constraint that makes it more than a copy: the actions have to be referenced by full path, because a relative path in a called workflow resolves against the caller's checkout, not the repo holding the workflow.

- Around line 106-107: Update the 0.x release examples in the README to describe
the minor tag corresponding to the release, not always v0.1. Clarify that a
0.1.2 release uses v0.1, while a 0.0.x release uses v0.0, including in the
explanation of levels: minor.
- Line 109: Revise the SemVer statement about v0 and v1 to describe the
project’s tag behavior as a convention, not a SemVer requirement; clarify that
SemVer permits any change in 0.y.z.

"A 0.x release resolves v0 and v0.1" read as though the minor tag were always v0.1. It is the release's own minor, so 0.0.5 resolves v0 and v0.0. Reported by CodeRabbit on PR 3.
"Semver puts breaking changes in the minor below 1.0.0" is not what the spec says. Item 4 says of 0.y.z only that anything may change at any time, so a 0.x minor is free to break rather than required to carry the breaks. The conclusion is unchanged: v0 crosses breaking changes and v1 does not. Reported by CodeRabbit on PR 3.

I think what this does currently for potentially rc releases is buggy.
Think the following example:
I publish 1.4.0-rc1 - v1 is tracking that now.
After i publish 1.3.1 the v1 won't be moved to track that. It will remain pointing to the 1.4.0-rc1.
Similar with publishing multiple RCs. maybe it's simple to not move on RCs and only default into using the 3-part like readReleaseTag ?
Probably if you agree with what the expected functionality should be, we should also add test coverage.

That's not how it works. 🤔 The only time a RC would claim a v1 floating tag is if both of the following are true:
- No released version exists in that tag's line. A release is a three-part tag with no - suffix, so for v1 that means no plain 1.x.y tag at all. The floating tags are tags in the repo too, but v1 and v1.0 have fewer than three parts and are skipped, so the tags an earlier RC moved never count as a release of the line. (Note: The "fewer than three parts" bit is something I just fixed: d7eba10)
allow-prereleasesis enabled
Examples, with tags created in this order and allow-prereleases enabled:
| Published | Released 1.x at the time |
Tags it moves | v1 points at |
v1.0 points at |
|---|---|---|---|---|
1.0.0-rc.1 |
none yet | v1, v1.0 |
1.0.0-rc.1 | 1.0.0-rc.1 |
1.0.0-rc.2 |
still none; the v1 and v1.0 rc.1 just moved are floating tags, not releases |
v1, v1.0 |
1.0.0-rc.2 | 1.0.0-rc.2 |
1.0.0 |
still none; it is the first | v1, v1.0 |
1.0.0 | 1.0.0 |
1.1.0-rc.1 |
1.0.0 |
v1.1 only |
1.0.0 | 1.0.0 |
If you have a v1 and v1.0 tags from previous, stable, releases and you tag v1.1.0-RC1, it would create a floating tag for v1.1 but leave both v1 and v1.0 alone.
There's tests that cover this in tests/actions/resolve-floating-tags/resolve.test.js under prereleases -> with allow-prereleases on.
For your specific example, with tags created in this order and allow-prereleases enabled:
| Published | Tags it moves | v1 points at |
v1.3 points at |
v1.4 points at |
|---|---|---|---|---|
1.3.0 |
v1, v1.3 |
1.3.0 | 1.3.0 | — |
1.4.0-rc.1 |
v1.4 |
1.3.0 | 1.3.0 | 1.4.0-rc.1 |
1.3.1 |
v1, v1.3 |
1.3.1 | 1.3.1 | 1.4.0-rc.1 |
1.4.0 |
v1, v1.4 |
1.4.0 | 1.3.1 | 1.4.0 |
Without allow-prereleases, which is the default and what the workflow in this PR uses, row 2 moves nothing and v1.4 does not exist until 1.4.0 ships. The other three rows are the same.
This RC functionality was a bit of an experiment on my end to try to find a way to provide ways for devs to test RCs of these Actions (or Actions in other repos that decide to use these Floating Tag Actions) without having to rely on a branch and then once it was fully tagged, it would not require them to update their workflows (They could use the v1.4.0-RC1 tag as @v1.4 and then once v1.4.0 is out of pre-release, @v1.4 still works).
We could remove it entirely, but we'd want to still have that check in place to ensure that Pre-Releases don't move tags. It is already disabled by default (and it is disabled on this Repo currently), we'd just be removing all the extra cases for when it is enabled where the special Pre-Releases logic takes place.
Two releases published close together ran in parallel, each reading the tag list and writing to it, so the later write won regardless of which release was newer. One concurrency group for the workflow serialises them. queue: max because the default, single, keeps one run pending and cancels the one already waiting. Three releases at once would have moved the tags for the first and the last and dropped the middle. Reported by dpanta94 on PR 3.
The job has no run: steps, and neither action shells out to git or reads the working tree. They write through the API with the token they are handed, so the credentials checkout stores in .git/config are never used and only sit there for whatever gets added to the job later. Reported by dpanta94 on PR 3.
run() read every tag in the repository before looking at the tag it was given, so a release that owns nothing paid for the paginated call anyway. The steps now run cheapest first. A tag that is not a version, and a level that is not a level, are settled without a request. A prerelease costs the single release lookup, and not even that when a `-` suffix has already answered: the regex is conclusive in that direction, where its silence is not, because a plain 1.3.0 can still be marked a prerelease on GitHub and no tag name shows it. latest 0 requests, was the whole tag list 1.4.0-rc.1, prereleases off 0 requests 1.3.0 flagged, prereleases off 1 request, never the tag list a level that is not a level 0 requests resolveFloatingTags keeps the same steps in the same order for a caller that already holds the tags, so the shared parts are functions now: resolvedNothing, isPrereleaseRelease, prereleaseSkipped, decideTags and report. Each has its own cases, as the rest of the file does. resolveFloatingTags is left orchestrating, and the order it asks in is observable: a bad tag beside a bad level reports the tag rather than throwing over the level. Nothing covered that, and moving readLevels above the tag check passed every test while changing it. Three cases pin it now. Reported by dpanta94 on PR 3.
The job set up bun to install and node to run, for one package.json and tests written against node:test. Only node is needed. `npm install` rather than `npm ci`: ci installs from a committed lockfile and fails without one, and no lockfile is committed here on purpose. Each run resolves the newest versions the ranges allow, so the @actions/github and @actions/core the tests drive cannot quietly drift from the ones a release runs against. Every lockfile is ignored now, not just bun's, since npm install writes one locally. Reported by dpanta94 on PR 3.
listTags returns every tag in the repository, which includes the floating tags the action itself wrote. Read as versions, v1.0 became 1.0, and isInLine counted that as a release of the 1.x line, so the action took its own previous output as proof the line had shipped. With allow-prereleases on, that stopped a second candidate claiming the major tag: publishing 1.0.0-rc.2 after 1.0.0-rc.1 moved only v1.0 and left v1 on rc.1, because the v1.0 written by rc.1 read as a released 1.0. A release always has three parts and a floating tag never does, so releasedVersions now drops any candidate with fewer.

Demo
Loom walkthrough of all of this working, against real releases in plugin-toolbox-playground. Note: This was done with a Workflow that references the Composite Actions here. Creating a Reusable Workflow for this is deferred in a new README checklist item as it would require us locking down to a specific version as part of the workflow.
What this does
Tagging a release
v1.2.3also creates or moves two shorter tags,v1andv1.2, pointing at thesame commit. That is all a floating tag is: a name that keeps moving to the newest release of its
line.
They exist so another repo can use this one's actions and workflows by a reference that does not
change:
@v1then follows every 1.x release without the consuming repo editing anything, which is whatreplaces
@main. Composer resolves a range like^1.0on its own; GitHub Actions has no equivalent,so the tags have to be written. This writes them on every published release.
House rule 2 is where the pinning convention comes from.
What is here
resolve-floating-tagsmove-git-tagsrelease-tags.ymltest.ymlSplit in two so either half works alone, and so a repo can build and commit between them: the
resolver never touches commits, and
move-git-tagstakes the commit as an input. Each README coversits own inputs, outputs and rules.
Started from the tag half of changelogger's
publish.yml. Its build and publish half does not apply: these actions are YAML and JS in the repo, so the release tag already names the commit consumers should get.The decisions worth reviewing
Most of the work is in the cases where "move the tag to the newest release" needs a definition.
Each tag is decided on its own line. If 1.3.0 is already out and you tag 1.2.5,
v1.2moves andv1stays on 1.3.0. Otherwise every@v1consumer silently drops to older code. A newer major neverholds a lower line back, so a backport still gets its own tags.
A fourth version part is a hotfix in the same minor line, not a line of its own, so a repo that
writes
1.2.3.1only when it needs to needs no configuration. Nothing floats at the patch level, sothe hotfix moves
v1.2; thev1.2.3release tag keeps pointing at 1.2.3.Prereleases are skipped by default, detected from a
-suffix or GitHub's flag without thecaller passing anything.
allow-prereleaseslets one own a tag whose line has had no release yet, so@v1.4can be tested before 1.4.0 ships while@v1keeps handing everyone a released version. Buildmetadata is not a prerelease.
A read that fails stops the job. An empty tag list cannot stand in for an unread one, because a
repo with no tags returns the same thing and the comparison would read it as nothing being newer,
moving every tag onto whatever was published last. Same for an unreadable prerelease flag. Nothing
moves, so re-running is enough.
Versions come from git tags, not a release listing. A release listing is ordered by publication
date and capped, so a high version published long ago sits past the end and the comparison would move
v1backwards onto the release being published. Tags have no cap.Refs are written through the API, not a force push, so the tag name never disappears and a Release
stays attached. Each ref is read with
git.getReffirst: a 403 from a protected tag must fail the jobrather than be retried as a creation.
How it runs
The logic is in
resolve.jsandmove.js, run byactions/github-script, which supplies the Noderuntime and an authenticated Octokit. Nothing to install and no bundle to build, so a change is
reviewable as a diff. Inputs arrive through
process.env, never interpolated into the script.The default token is the calling workflow's
github.token, scoped to the calling repo, so a repousing these needs no secret.
Testing
97 tests over the real clients, with only the network replaced:
githubis an Octokit from@actions/githubgiven afetchthat answers from rules and records every request, so an assertionis the request the action would have sent.
coreis the real@actions/corewriting to a temporaryGITHUB_OUTPUT.bun installonce, thennode --test. No lockfile: nothing built is versioned here, so each runresolves the newest versions the ranges allow, which is what a consuming repo gets.
Not in this PR
The release itself is still cut by hand. The changelog and release process from
Phase 7 is untouched, and so is actionlint over the manifests.
release-tags.ymlis a file to copy, not a workflow to call. Aworkflow_callwrapper would leta repo write a
uses:instead, which is what house rule 1 asks for, andis listed under Phase 3. It needs the actions referenced
by full path rather than
./, since a relative path in a called workflow resolves against thecaller's checkout.
