fix(ci): restore megalinter gate on main (hadolint, editorconfig, trufflehog) - #286
Conversation
…fflehog) Megalinter has been red on main since the v10 image / trufflehog 3.96 toolchain drift. Three independent findings, fixed at the source: 1. hadolint DL3066 (Dockerfile:32): use numeric UID (USER 1000) — the user is created with --uid 1000 a few lines above. 2. editorconfig-checker: docs/TROUBLESHOOTING.md contained mixed CRLF/LF line endings (introduced via PR #285); normalized to LF per .editorconfig (end_of_line = lf). 3. trufflehog >=3.96 Lob detector flags every `test_*` function name as a verified Lob key (Lob test keys share the `test_` prefix). Excluded only the Lob detector via REPOSITORY_TRUFFLEHOG_ARGS so all other secret detectors stay active. Verified locally: 0 findings with trufflehog 3.96.0 after exclusion. Validation: - trufflehog 3.96.0 --only-verified --exclude-detectors=Lob: clean - pytest tests/test_catalog_resolve.py tests/test_cli.py: 35 passed

💡 Result:
In MegaLinter 10.0.0, the configuration variable REPOSITORY_TRUFFLEHOG_ARGUMENTS is used to pass custom command-line arguments to the TruffleHog linter [1]. Configuration details: - Variable: REPOSITORY_TRUFFLEHOG_ARGUMENTS - Purpose: Defines user-custom arguments to be added to the linter CLI call [1]. - Example usage: -s --foo "bar" [1]. - Common use case: Many users utilize this variable to pass flags like --only-verified to reduce false positives, as recommended by TruffleHog developers [2]. Note that there is no variable named REPOSITORY_TRUFFLEHOG_ARGS; the correct and documented variable name used by MegaLinter to pass custom arguments is REPOSITORY_TRUFFLEHOG_ARGUMENTS [1]. You can define this in your.mega-linter.yml file or via environment variables [3].

Rename the TruffleHog argument key.
The v10 MegaLinter workflow recognizes REPOSITORY_TRUFFLEHOG_ARGUMENTS, not REPOSITORY_TRUFFLEHOG_ARGS. Rename this key so MegaLinter passes --exclude-detectors=Lob to TruffleHog; otherwise the false-positive failures can remain.

Source: MCP tools
REPOSITORY_TRUFFLEHOG_ARGS is not honored by the MegaLinter trufflehog descriptor; the supported mechanism is a workspace .trufflehogignore file, which MegaLinter merges into the generated --exclude-paths file. Excludes packages/create-awesome-python-app/tests/ only — production code remains fully scanned.
