negative durations mean “in the future”), matching the intent used elsewhere in tests (e.g. `since: '1m', until: '-1s'`). + +### 2) Inspect parsing likely breaks for multi-target inspect calls + +Files: +- `packages/vscode-container-client/src/clients/FinchClient/FinchClient.ts` (inspect containers/images/networks/volumes) + +Context: +- `DockerClientBase` adds `--format "{{json .}}"` to `* inspect` commands, which typically yields **one JSON object per line** when inspecting multiple targets. +- Finch parse functions currently do `JSON.parse(output)` and handle `Array` vs single `object`, but **do not handle newline-separated multiple JSON objects**. + +Impact: +- `inspectImages({ imageRefs: [...] })`, `inspectContainers({ containers: [...] })`, etc. may fail when passed multiple refs (depending on Finch/nerdctl’s `--format` behavior). + +Recommendation (pick one): +- **Option A:** Override the `getInspect*CommandArgs` methods for Finch to omit `--format` and rely on the default JSON array output (if Finch/nerdctl returns arrays by default). +- **Option B:** Make parsing tolerant: + - Try `JSON.parse(output)` first. + - If that fails, fall back to `output.split('\n')` and parse per-line JSON (same as `DockerClientBase`). + +### 3) Shell injection / portability risks in `readFile` and `writeFile` + +File: `packages/vscode-container-client/src/clients/FinchClient/FinchClient.ts` + +- Both overrides use `bash -c ""` with interpolated values (`this.commandName`, `options.container`, `options.path`). +- Even though these are quoted with `"..."`, a container name/path containing `"` or shell metacharacters can still cause incorrect behavior. +- This also assumes `bash`, `mktemp`, and `tar` exist on the host environment. + +Recommendation: +- Avoid `bash -c` where possible: + - Prefer invoking `finch cp` with argv arrays and do tar/mktemp in Node, or + - Use `/bin/sh -c` with robust escaping via `ShellQuotedString` (matching patterns already used in `DockerClientBase` for exec/stat/list). +- At minimum: explicitly document platform assumptions (Finch is typically macOS) and harden quoting. + +## Medium-Priority Improvements (Should Follow Soon) + +### 1) Fix incorrect override parameter types + +File: `packages/vscode-container-client/src/clients/FinchClient/FinchClient.ts` + +- `parseInspectNetworksCommandOutput` and `parseInspectVolumesCommandOutput` declare `options` as `List*CommandOptions` types, but they override `Inspect*` parsing methods. +- It compiles today (because `options` is unused), but it weakens type safety and is confusing for future maintenance. + +Recommendation: +- Align parameter types with the base class (`InspectNetworksCommandOptions`, `InspectVolumesCommandOptions`). + +### 2) “Epoch” fallbacks (`new Date(0)`) may produce misleading UX + +Files: +- `packages/vscode-container-client/src/clients/FinchClient/FinchListContainerRecord.ts` +- `packages/vscode-container-client/src/clients/FinchClient/FinchListImageRecord.ts` +- `packages/vscode-container-client/src/clients/FinchClient/FinchInspectVolumeRecord.ts` + +Observation: +- Several normalizers use `new Date(0)` when the CLI omits or malforms timestamps. + +Recommendation: +- If the CLI output should always include a timestamp in strict mode: fail in strict mode instead of silently returning epoch. +- If missing timestamps are expected: consider using `new Date()` (less misleading than 1970) or a documented sentinel strategy. For inspect volume, also validate `new Date(CreatedAt)` isn’t `Invalid Date`. + +### 3) Volume label parsing drops label strings + +Files: +- `packages/vscode-container-client/src/clients/FinchClient/FinchClient.ts` (listVolumes parsing) +- `packages/vscode-container-client/src/clients/FinchClient/FinchInspectVolumeRecord.ts` + +Observation: +- `Labels` can be a string in Finch output (including potentially `key=value` pairs), but the implementation treats *any* string as “no labels” (`{}`). + +Recommendation: +- If labels are emitted as `key=value,...`, parse via `parseDockerLikeLabels`. +- If Finch emits `""` specifically for no labels, treat only `""` as empty. + +### 4) Deduplicate size parsing logic + +File: `packages/vscode-container-client/src/clients/FinchClient/FinchListImageRecord.ts` + +- There’s an existing `tryParseSize` utility in `DockerClientBase`. + +Recommendation: +- Reuse `tryParseSize` to reduce divergence and ensure consistent unit handling across clients. + +### 5) Event filters: labels are silently ignored + +Files: +- `packages/vscode-container-client/src/clients/FinchClient/FinchClient.ts` + +Observation: +- `getEventStream` options include `labels`, but Finch doesn’t implement label filtering. + +Recommendation: +- Either document that labels are unsupported for Finch, or implement best-effort filtering if the event payload provides label data. +- Consider rejecting with a clear `CommandNotSupportedError` when `labels` are provided (to avoid surprising “filters do nothing” behavior). + +## Testing Notes + +- Ran locally: + - `npm run --workspace=@microsoft/vscode-container-client build` + - `npm run --workspace=@microsoft/vscode-container-client lint` + - `npm test --workspace=@microsoft/vscode-container-client` (unit tests;
