Replace where.exe with a mise-managed linker path. Supported Nano Server hosts do not provide where.exe, so line 312 can leave Cargo without the MSVC linker override. Use the staged MSVC path or another mise-managed, pinned lookup instead of a host utility.

ls-lint 1.x configuration ignore list glob syntax quoted paths spaces

💡 Result:

In ls-lint 1.x, the ignore configuration accepts a list of patterns to exclude files and directories from linting [1]. While directory patterns (such as globbing) are explicitly supported for the ls (naming rules) configuration, the official documentation notes that these advanced glob patterns are not yet supported for ignore configurations [1]. Regarding the specific syntax for the ignore list: 1. Glob Support: While the documentation states directory patterns are not yet supported for ignore, practical usage and community examples indicate that standard glob patterns, such as /*.png or bazel-*, are often used and accepted in the ignore list [2]. 2. Spaces and Quoted Paths: As the .ls-lint.yml file is a standard YAML file, paths containing spaces should be enclosed in quotes (e.g., 'path with spaces') to ensure they are parsed correctly as strings by the YAML parser [2]. If you have a directory or file name with a space, wrapping the entry in single or double quotes is the standard approach to prevent syntax errors [2]. To configure the ignore list effectively: - Use a YAML list format [1][2]. - Quote any path containing spaces to ensure the YAML parser handles the string correctly [2]. - For simple directory or file names, standard entries are sufficient (e.g., - node_modules) [1][3][2]. Example configuration: ignore: -.git - node_modules - 'my folder with spaces' - '/*.png' Because the tool treats entries as strings, standard YAML escaping rules apply for special characters or spaces [2].

Citations:


Make the glob detector line-scoped.

-\s+\S*[*?\[{] misses quoted ignore entries that contain spaces, such as - "build artifacts/*". Use a line-scoped pattern so every YAML list entry is checked.

pnpm allowBuilds introduced v10.26.0 ignoredBuiltDependencies removed pnpm v11 official documentation

💡 Result:

The allowBuilds configuration field was introduced in pnpm v10.26.0 [1][2]. It functions as a centralized map that allows users to explicitly permit (true) or deny (false) the execution of build scripts for specific packages [3][2]. In pnpm v11.0.0, legacy build-dependency settings—specifically onlyBuiltDependencies, onlyBuiltDependenciesFile, neverBuiltDependencies, ignoredBuiltDependencies, and ignoreDepScripts—were officially removed [4][5][6]. Users are now required to use allowBuilds as the exclusive method for managing package build permissions [3][4]. When migrating to v11, these deprecated settings are replaced by allowBuilds in the following manner [7]: - onlyBuiltDependencies maps to allowBuilds: { <package>: true } [7]. - neverBuiltDependencies and ignoredBuiltDependencies map to allowBuilds: { <package>: false } [7]. - onlyBuiltDependenciesFile entries are merged into the allowBuilds map as true [7]. - ignoreDepScripts has no direct equivalent and is removed by the migration process [7].

Citations:


Pin pnpm for every install path. The mise locks use v11.5.1 and v11.21.0, which support allowBuilds, but the mise configurations request latest, package.json has no packageManager, and the Dockerfile installs pnpm without a version. Pin each path to pnpm v10.26.0 or newer.

Reset all per-run input state before reconnecting or starting a new run.

Resetting only agentId leaves stale inputPointer state, and some modules also retain parsed input. Clear these values before creating the new socket or beginning the next run so rejected or delayed input cannot be reused.

Apply this consistently to:

  • services/ws-modules/dotnet-math1/pkg/et_ws_dotnet_math1.js
  • services/ws-modules/java-math1/pkg/et_ws_java_math1.js
  • services/ws-modules/kotlin-math1/pkg/et_ws_kotlin_math1.js
  • services/ws-modules/dart-math1/lib/dart_math1.dart

Confirm the repeat-run contract and add regression coverage.

services/ws-modules/dotnet-math1/pkg/et_ws_dotnet_math1.js lines 26-27, update
the reconnect initialization near agentId to also set inputPointer to null
before creating the new socket; in
services/ws-modules/java-math1/pkg/et_ws_java_math1.js lines 25-26 and
services/ws-modules/kotlin-math1/pkg/et_ws_kotlin_math1.js lines 24-25, reset
both inputPointer and input to null alongside agentId.

Apply the same fix in `@services/ws-modules/dart-math1/lib/dart_math1.dart` around
lines 79 - 94: The Dart run path must clear inputPointer before waiting for new
input.
