If a reader could derive it from +the code in front of them, delete it: a redundant comment still has to be +maintained, will eventually contradict the code, and dilutes the comments that +matter. + +The operative rules are in `AGENTS.md`, kept short so they stay in an agent's +context. This document is the reasoning and the worked examples behind them, plus +how to run the linter. + +## Comment the current state + +Describe the code as it is. Not what it used to be, not what changed, not why it +changed. A comment that narrates history is stale the moment the next change +lands, and git already holds that record. + +When you know the history and it explains the shape of the code, the useful half is +the reason, not the sequence. State the reason: + +```java +// Don't: +// This used to reimplement the modal internals, which is how the procurement +// dialogs drifted from the billing ones. + +// Do: +// Thin wrapper over the shared Modal: duplicating its portal and focus trap is +// how dialogs drift apart. +``` + +Future state is the exception, and it belongs in a TODO with an issue. + +## The four jobs + +**Contract.** What a caller must know that the signature cannot say: +preconditions, invariants, units, ownership and lifetime, thread-safety, error +semantics, side effects. + +The bound is the surface, not the volume: document the contract of everything a +caller outside the file can reach, and nothing else. Inside that surface say +whatever a caller needs; outside it a comment earns its place on the same terms as +any other. + +```java +/** + * Authority on which filesystem locations a policy may read or write.

"Do not remove, +it prevents Z." + +**Map.** A short orientation at the head of a genuinely complex file: what it owns, +and what it deliberately does not. + +## The test that decides it + +A comment earns its place when it sits at a different level of detail than the line +below it: lower, stating a precise fact the code implies but does not say, or +higher, giving intent a reader would otherwise assemble from ten lines. +Same-altitude is the definition of redundant. + +- **Delete it.** Is any information lost? If not, it stays deleted. +- **Could a name carry it instead?** A better identifier, an extracted function or + a named constant beats a comment. Prefer the code change. + +## What not to write + +| Don't | Instead | +| --- | --- | +| `// Handle drag start` above `handleDragStart` | Nothing. The name already says it. | +| `// ─── Types ───`, `// Helpers`, `// ====` | If a file needs internal signposting, split the file. | +| `// Step 1:` narrating a function body | Extract functions. If the steps need labels they need names. | +| `// No longer needed`, `// Previously this used X` | State why the code is as it is now, or nothing. | +| Commented-out code | Delete it. Git remembers. | +| `@param blob - The blob to download` | Omit the tag rather than pad it. | +| Docs on a self-explanatory member | Nothing, unless there is a real constraint to state. | + +Step numbering is fine where it labels a genuinely numbered thing, such as a wizard +step or a step in a written test procedure. It is narration when it numbers the +lines of one function. + +## Comments at the end of a line + +A trailing comment usually does a different job from one above the code: it decodes +the line it sits on. Those are worth keeping, and the linter leaves them alone. + +```java +byte[] pdfBytes = {0x25, 0x50, 0x44, 0x46}; // "%PDF" +long maxAttachmentSize = 50L * 1024 * 1024; // 50 MB +double buffer = 0.10; // 10% headroom +default -> toBytes(value, 2); // MB +``` + +Each overlaps in words with the code and each adds the interpretation the code +leaves implicit, which is the lower-altitude case the test above asks for. So +`CMT001` does not judge trailing comments; on this codebase it would have been +wrong about roughly six in seven of them. + +What still applies is anything that does not depend on the code below: a trailing +`// TODO fix this` is as unowned as one on its own line, and a trailing +`// this used to run before the flush` narrates history wherever it sits. + +A comment block over about 12 lines, outside a file or type header, is usually a +sign the code needs restructuring. If it is genuinely product documentation, it +belongs in the docs repo. + +## TODOs + +A TODO needs an issue, because an issue is the only part that will close it: + +```java +// TODO(#1234): re-enable the checkout gate once account syncing lands +``` + +An owner is not a substitute: a username goes stale when someone changes team and +means nothing to an outside contributor. If the work is not worth an issue it is +not worth a TODO, and the options are to do it now or leave the code alone. A +question is not a TODO. + +## Per language + +**Java.** Google Java Style, which this repo already formats to. Its §7.3.1 +exception applies: omit Javadoc on a self-explanatory member where there is +genuinely nothing to add, but do not cite it to skip something a reader needs. +Summary fragments are noun or verb phrases, not sentences starting "This method +returns". + +**TypeScript.** JSDoc on the `@app/*` seams, exported hooks, and anything crossing +a layer boundary. No `@param`/`@returns` that restates a typed signature. JSX +comments follow the same rules as any other. + +**Python.** Docstrings on modules, public functions and Pydantic models where the +contract is not obvious from the type. + +## The linter + +```bash +task comment-lint # what the working tree adds over HEAD +task comment-lint:branch # what the branch adds over origin/main (BASE= to change) +task pre-commit:comment-lint:ci # the fixture corpus, then the diff +``` + +`comment-lint` is the pre-commit question, so it reports nothing once you have +committed; on a CI pull request it compares against the target branch via +`GITHUB_BASE_REF`. `comment-lint:branch` is the review question. The corpus checks +the rules themselves rather than the code under review, so it runs on CI and before +a rule change, not on every local commit. + +`task comment-lint` also runs inside `task pre-commit`, and as a Claude Code `Stop` +hook, so an agent is told before it finishes a turn and fixes the comment inside +that turn. Stop rather than per file write: a run costs the same for one file as for +twenty-five, and half of all writes in a turn go to a file already written in it. + +Findings are scoped to comment text that is new, not to lines git calls new, so +reindenting or moving code does not resurface comments you did not write. + +The rules are the `RULES` object in +[`scripts/lint/comment-rules.mjs`](../scripts/lint/comment-rules.mjs); the exact +condition for each is the predicate of the same name in that file, with the +readings it deliberately excludes beside it. + +**Every rule blocks.** A rule that only warns is a rule nobody acts on. So a +finding you believe is wrong is a bug in the rule, not something to live with: +narrow the rule, or mark the line and say why. + +Every comment form the repo writes is covered: `//` and `/* */`, Javadoc and JSDoc, +JSX comments, `#`, and Python docstrings. `CMT007` reads all three parameter +conventions in use here, Javadoc/JSDoc `@param`, Sphinx `:param name:` and Google +`name: description` under `Args:`. + +Two engines, one rule set. `.ts`/`.tsx`/`.mjs` go to an oxlint JS plugin, so +comments come from the parser: a `//` inside a string is not a comment, and JSX +`{/* … */}` is. `.java`/`.py` go to a line scanner. Neither reads the other's +files, so they cannot disagree about one file. `scripts/lint/fixtures/` is the +corpus that keeps them meaning the same thing. + +### When a finding is wrong + +Name the rule on the line above: + +```ts +// comment-lint-allow: CMT002 +// ─── kept deliberately, because ─── +``` + +There is no form that disables every rule, and the directive has to earn its +place. `CMT008` reports one that names something which is not a rule, and one that +silences nothing, so a typo does not read as a suppression and a stale +suppression does not sit there blinding the line. The whole comment must be the +directive; prose that mentions the syntax is just prose. + +If you reach for this more than occasionally the rule is wrong: fix it in +`comment-rules.mjs` and update the fixture corpus in the same commit, so the diff +shows what moved. + +### The existing backlog + +`task pre-commit:comment-lint:all` reports the whole tree and never fails. There is +a standing backlog being cleared by directory; diff scoping is what keeps it off +whoever touches a file first. + +To turn the editor hook off, put `{ "env": { "COMMENT_LINT_HOOK": "0" } }` in +`.claude/settings.local.json`. The commit-time gate still applies, so you lose the +early warning rather than the check. diff --git a/devGuide/README.md b/devGuide/README.md index 5e8486f013..2ddaff63c3 100644 --- a/devGuide/README.md +++ b/devGuide/README.md @@ -8,6 +8,7 @@ This directory contains all development-related documentation for Stirling PDF. - **[DeveloperGuide.md](../DeveloperGuide.md)** - Main developer setup and architecture guide (in repo root) - **[Taskfile.yml](../Taskfile.yml)** - Unified task runner for all build/dev/test/lint commands - **[EXCEPTION_HANDLING_GUIDE.md](./EXCEPTION_HANDLING_GUIDE.md)** - Exception handling patterns and i18n best practices +- **[CODE_COMMENTS.md](./CODE_COMMENTS.md)** - What a comment is for, what not to write, and the `task comment-lint` rules - **[HowToAddNewLanguage.md](./HowToAddNewLanguage.md)** - Internationalization and translation guide - **[STORAGE_ENCRYPTION_AT_REST.md](./STORAGE_ENCRYPTION_AT_REST.md)** - Encryption at rest for stored files: key setup, migration, revocation, rotation diff --git a/docker/backend/Dockerfile b/docker/backend/Dockerfile index 39bb60bdef..ec7d7a7304 100644 --- a/docker/backend/Dockerfile +++ b/docker/backend/Dockerfile @@ -45,7 +45,7 @@ RUN JPDFIUM_PLATFORM="$([ "$TARGETARCH" = arm64 ] && echo linux-arm64 || echo li --no-daemon # Stage 2: Extract Spring Boot Layers -FROM eclipse-temurin:25-jre-noble@sha256:fbcf915c585659b30eb766ada4d6d7cfc9ec1040bf521e95bf61b10a25af73db AS jar-extract +FROM eclipse-temurin:25-jre-noble@sha256:b4c93a50fc67612798db73d68ca3b0ee4ebdd51736e59cca370e689b9797037e AS jar-extract WORKDIR /tmp COPY --from=app-build /app/app/core/build/libs/*.jar app.jar RUN java -Djarmode=tools -jar app.jar extract --layers --destination /layers diff --git a/docker/base/Dockerfile b/docker/base/Dockerfile index 06e1b6e601..0c73738214 100644 --- a/docker/base/Dockerfile +++ b/docker/base/Dockerfile @@ -5,7 +5,7 @@ ARG TARGETPLATFORM # Stage 1: Build and strip Calibre -FROM ubuntu:noble@sha256:561618e2c15bf2397621dd04f96926663a3b5616c189cf7e38db7e82f5c538ea AS calibre-build +FROM ubuntu:noble@sha256:33ceb71981b602c1a7443a53469e4dba065f7503eab3078a2d7a57a2ab987517 AS calibre-build ARG TARGETPLATFORM ARG CALIBRE_VERSION=9.13.0 ARG CALIBRE_STRIP_WEBENGINE=false @@ -274,7 +274,7 @@ RUN if [ "${CALIBRE_STRIP_WEBENGINE}" = "true" ]; then \ # Stage 2: Build Ghostscript from source -FROM ubuntu:noble@sha256:561618e2c15bf2397621dd04f96926663a3b5616c189cf7e38db7e82f5c538ea AS gs-build +FROM ubuntu:noble@sha256:33ceb71981b602c1a7443a53469e4dba065f7503eab3078a2d7a57a2ab987517 AS gs-build ARG TARGETPLATFORM ARG GS_VERSION=10.07.1 @@ -298,7 +298,7 @@ RUN --mount=type=cache,target=/var/cache/apt,sharing=locked \ # Stage 3: Build PDF Tools (QPDF and ImageMagick 7) -FROM ubuntu:noble@sha256:561618e2c15bf2397621dd04f96926663a3b5616c189cf7e38db7e82f5c538ea AS pdf-tools-build +FROM ubuntu:noble@sha256:33ceb71981b602c1a7443a53469e4dba065f7503eab3078a2d7a57a2ab987517 AS pdf-tools-build ARG TARGETPLATFORM ARG QPDF_VERSION=12.4.0 ARG IM_VERSION=7.1.2-29 @@ -343,7 +343,7 @@ RUN mkdir -p /magick-export/usr/bin \ # Stage 4: Build Python venv -FROM ubuntu:noble@sha256:561618e2c15bf2397621dd04f96926663a3b5616c189cf7e38db7e82f5c538ea AS python-venv-build +FROM ubuntu:noble@sha256:33ceb71981b602c1a7443a53469e4dba065f7503eab3078a2d7a57a2ab987517 AS python-venv-build ARG TARGETPLATFORM ARG UNOSERVER_VERSION=3.7 @@ -368,7 +368,7 @@ RUN --mount=type=cache,target=/root/.cache/pip,sharing=locked \ # Final runtime image - the actual base image -FROM eclipse-temurin:25-jre-noble@sha256:fbcf915c585659b30eb766ada4d6d7cfc9ec1040bf521e95bf61b10a25af73db AS runtime +FROM eclipse-temurin:25-jre-noble@sha256:b4c93a50fc67612798db73d68ca3b0ee4ebdd51736e59cca370e689b9797037e AS runtime SHELL ["/bin/bash", "-o", "pipefail", "-c"] diff --git a/docker/embedded/Dockerfile b/docker/embedded/Dockerfile index 3c5c1279d8..9a93f54a75 100644 --- a/docker/embedded/Dockerfile +++ b/docker/embedded/Dockerfile @@ -48,9 +48,23 @@ ENV STIRLING_FLAVOR=${STIRLING_FLAVOR} # processor or AI layers change; defaults false so normal builds skip the extra app. ARG BUILD_PROCESSOR=false +# Which Stirling account the portal connects to.
