* renaming from gitTally to Werkator * Rename GitTally to Werkator `gitTally` is the name of another product in the git space, so the rename is a precaution; nothing about what the build system does changes. The name follows one rule: `Werkator` where it is prose, capitalized where it is a Kotlin type and its file, lowercase everywhere a machine reads it — the command, packages, paths, configuration keys and values, the Gitea check context. Environment variables keep their convention and are uppercase throughout. Every configuration file is still found under its pre-rename name (`ConfigFiles`): `.gittally.yml` at the repository root, in a build worktree and as committed on a branch, `.git/gittally/.gittally.yml` for the machine layer. The current name wins where both exist, and the old file is then ignored rather than merged — two files side by side are a half-done rename, not a layering. Without the fallback an installation that updated without renaming would not fail: a configuration that is not found leaves every setting at its default, so it would come up looking healthy while having forgotten its credentials and its builds. `docs/werkator-migrationsplan.md` lists what the fallback does not cover and has to be moved by hand — above all the state directory `.git/werkator/`, which holds the build history, the control token and the worktrees, and has no fallback of its own. `docs/migration-from-legacy.md` is deleted with this: it mapped the legacy script's environment variables, and every host it addressed has long since moved to the YAML configuration. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * Move the pre-rename state directory at the first start The configuration is found under either name, the state is not: build history, control token, auto-build slots and worktrees live at one fixed path. An installation that updates without moving `.git/gittally` would not fail — it would come up with an empty history and a fresh control token, quietly. So the first start moves it instead of the release notes asking for it. Only when the old directory exists and the new one does not. Where both exist nothing is touched and a warning names the leftover: which of the two is the live state is not something to guess. A failed move is an error in the log, never an abort — a CI must not hang on it. The worktrees are dropped rather than moved, since they point at their old path in both directions; `GitWorktreeWorkspaces` prunes the stale admin entry and recreates each on its branch's next build. A generated systemd unit moves with the directory and leaves its symlink dangling, which is warned about — the running service is unaffected, the next start is not. Runs from `CliRunner`, before any command resolves a path under the directory, and so before the second context of `server` exists.

The blanket rename rewrote those literals, so the converter was looking for `WERKATOR_*` — a spelling no host has ever written. Fed a real legacy file it would have found nothing and written an almost empty configuration, without an error, which is the same silent failure this rename is otherwise careful to avoid. The conversion has served its purpose with the vm2176 to vm4006 migration, so it goes instead of being repaired. What remains is the setup of a new instance: the preconditions, the credential prompt, and the machine configuration written mode 600 — now carrying the host's public URL as well, since that is host-specific too. Everything the repository builds comes from `init` and its templates. It also stops emitting a legacy `branches:` section, which step 18 is about to reject outright. `docs/plan/00-legacy-analysis.md` and `13-nginx-tls.md` get the real `GITTALLY_*` spelling back: they record what the old script read. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * Describe this repository's build with a build definition Its own `.werkator.yml` still used the deprecated `branches` section with an `autoBuild` schedule that was switched off. That section is read only while nothing defines a build at all, and step 18 rejects it by name — so this repository would have blocked the precondition of that step, which asks that no configuration still in play carries it. Nothing about the build changes: `builds.default` with `trigger.onPush` is a build of every new commit on every branch, which is what the branch section said. `config:print --full` resolves the definition completely and logs no deprecation warning any more. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * Stop documenting the pre-rename fallback for users Exactly one repository is configured with the old names, and it is migrated by hand in the same move as this release. The fallback is therefore a transition of days, not a feature anyone reading the release notes or the configuration reference has to plan around. Removed from `releases.html` and `docs/configuration.md`. The mechanism itself is unchanged and stays described where it is worked on: in `ConfigFiles`, in `StateDirMigration`, and in the migration plan. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * Bring the PR-doc to its final state The `statusContext` question is answered and marked as decided rather than left standing: it is the one value a human reads as a label, and it stays lowercase because Gitea matches it and the client reads it back, which makes it a value. Also records that the pre-rename fallback is deliberately absent from the release notes and the configuration reference. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * Release v1.0.0: Werkator The release after 0.9.21 is 1.0.0, because a product that changes its name is better off counting from one under it. The release note says as much, so the jump is not read as a claim about maturity — plan steps 14, 17 and 18 are still open. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * Correct the PR-doc about the version It claimed the PR carries no version bump, which the release commit made untrue, and records why the number is 1.0.0 instead of 0.9.22. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * Point the legacy references at the history `legacy/gitTally` was removed from the tree with the rename, but the README still described it as a reference kept in the repository, and the plan told an executing session to read parts of it — including step 14, which is open. The README section is gone; `docs/plan/README.md`, step 14 and the legacy analysis now say where the script actually is (`git show 7f55068^:legacy/gitTally`). Executed steps and ADR 0004 keep their wording: they record what was true when they ran. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * Retarget the links in the historic PR-docs The package rename moved every file the older PR-docs link to, leaving 60 dead links. Only the link targets are rewritten, never the visible text and never a statement: those documents record what was true when they were written, GitTally in the prose included. A snapshot may be outdated; it should still be navigable. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * Add the v1.0.0 deployment procedure for vm4006 Measured, not estimated: the state directory is 878 MB, of which 878 MB are the nine build worktrees. What cannot be recreated is 84 KB, so the snapshot before an in-place switch is instant and the rollback is one sequence of moves. Records the three expected non-failures — a cold Gradle volume, one image rebuild, containers left under the old label — and that `gitea.statusContext` needs no attention because it comes from the watched repository's committed configuration. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * Rename the machine configuration along with its directory Found by the deployment to vm4006: the move renames the directory and leaves the file inside it alone, so the machine configuration ended up at `.git/werkator/.gittally.yml` — a pair of names the lookup did not expect, because it pairs directory and file name. The instance resolved empty credentials, no public URL and none of the host's build definitions, and said nothing about it. That is the exact failure this change exists to prevent, produced by the change itself. `StateDirMigration` now renames the configuration with the directory, unless one under the current name is already there. `ConfigFiles` carries `.git/werkator/.gittally.yml` as a third candidate as well, for a directory somebody moved by hand, where the migration never runs and so can rename nothing. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * Let init see a configuration under its previous name `init --systemd` runs `init`, and its "already exists" check knew only the current name. On the one repository still carrying `.gittally.yml` it therefore wrote a fresh template `.werkator.yml` beside it — and since the current name wins, that repository would have built the template's `./gradlew test` instead of what its own configuration says. Found on vm4006, where the file was created in the watched working tree and removed again by hand. Both checks now ask `ConfigFiles`, so init decides existence by the same rule the loader uses to read. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * Record the v1.0.0 deployment to vm4006 Deployed from the branch as the final test of PR#1, and it did what a final test is for: it found two silent-failure defects before the service was started, both fixed and redeployed in the same window. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * Drop the control token left under the old localStorage key The key is named after the product, so the rename left every browser with a token under `gittally.controlToken`, which nothing reads any more and which "forget token" can no longer reach. It is a write-scope token in a browser store, not a password, but a secret nobody owns is worth one line to remove. Removed on load. The token on the server is unchanged, so re-entering it once per browser is all the rename costs.

Self-Contained Runtime Bundle Distribution
Status:
- proposed: 2026-08-10
- accepted: 2026-08-10
- rejected: -
- superseded: -
Decision [accepted]: Werkator is distributed for hosts without a Java runtime as a self-contained runtime bundle — a jlink-trimmed JRE plus werkator.jar plus a launcher script in one tarball, built by ./gradlew runtimeBundle.
The JAR stays the primary artifact; a GraalVM native image and a containerized Werkator runtime were rejected.
Context and Problem Statement
Werkator must run on Hostsharing container servers (the primary target, see ADR 0005).
These hosts provide git, Docker, make, and systemd user sessions, but no Java runtime, and nothing may be installed system-wide.
docs/bootstrapping.md sketched a containerized Werkator runtime as the future answer; that sketch was never validated against the operational details.
Considered Options
- jlink runtime bundle (trimmed JRE + jar + launcher, one tarball)
- GraalVM native image (single executable)
- Containerized Werkator runtime (the original
docs/bootstrapping.mdsketch)
jlink Runtime Bundle
A jlink-generated JRE with the pinned module list, the boot jar, and a bin/werkator launcher script, packed as werkator-runtime-linux-x64.tar.gz (~66 MB) and unpacked to ~/opt/werkator/ on the target host.
Good:
- No production-code changes and plain JVM semantics — no new failure modes.
- git and docker CLIs are used from the host; build worktree paths stay host paths.
init --systemdworks unchanged:java.homeand the running-jar path resolve into the bundle, so the generated unit points at<bundle>/jre/bin/javaand<bundle>/lib/werkator.jar(verified).- Every JDK 21 ships jlink — no new build-toolchain requirement.
Bad:
- A directory tree, not a single file (still one tarball to copy).
- JVM startup (~1-2 s) instead of native-image startup — irrelevant for a long-running server.
- The jlink image links glibc dynamically, so it is bound to an architecture and a minimum glibc.
Corrected on 2026-08-11: that minimum is not the build machine's glibc, as originally assumed here.
jlinkcompiles nothing — it copies the JDK vendor's prebuilt binaries out of the jmods, so the floor is the vendor's build environment. Measured over all 33 ELF files of the bundle produced by the Temurin 21 toolchain, the highest required symbol version isGLIBC_2.15, which every supported distribution exceeds. The build machine's glibc only matters if the toolchain resolves to a distribution-packaged JDK instead of Temurin.
GraalVM Native Image
Rejected because Spring AOT evaluates bean conditions at build time, and Werkator's dual-mode wiring cannot be represented in a single AOT arrangement:
the CLI context runs without web and with @Profile("!server") CliRunner, while the server subcommand starts a second SpringApplication with WebApplicationType.SERVLET and the server profile gating the watcher/metrics/nginx lifecycles.
Whichever profile and web type the AOT processing fixes, the other mode's beans are missing from the binary.
Supporting both would require replacing the profile wiring with runtime guards and collapsing the two context shapes — an invasive rewrite with regression risk for the JVM path, on top of the usual native-image reflection work (Jackson-bound config and persistence classes, picocli).
Containerized Werkator Runtime
Rejected for operational complexity: the image must bundle git and docker CLIs; the container needs a same-path $HOME mount plus a docker-socket mount and uid/gid mapping so that DockerBuildRunner's --volume $workspace:$workspace sibling mounts keep working; and the systemd unit must be hand-edited to a docker run invocation.
This remains the documented fallback if the runtime bundle ever becomes unworkable.
Consequences
docs/deployment.mddocuments the bundle path; the "Future: Docker-based Deployment" section indocs/bootstrapping.mdis replaced.- The pinned JDK module list in
build.gradle.ktsmust be re-checked (via the documented jdeps command) when dependencies change. - Deployment and migration for vm4006 follow plan step 15.
