Describe the bug

I ran into an issue, where swiftlint will run forever on linux and docker.
The command I'm using is
swiftlint lint --reporter markdown --output linter_result.md --config ./.swiftlint.yml

If I add a list of files that have to be check, it will end correctly and write the report into linter_result.md
For this I use:
swiftlint lint --reporter markdown --output linter_result.md --config ./.swiftlint.yml $(git --no-pager diff --name-only --diff-filter=ACMUd --relative main -- '*.swift')

this works perfectly, but every time we have changes in the rules or in the swiftlint version, I want to make sure that all files are scanned.

This does not happen either locally on M1 running macos 13.2.1 or on Github with macOS-12.

I tried using the docker image for 0.50.3 and the same thing happens, it will run indefinitely.

There are a few issues open/closed that could not help me:

  • issue: #4215
  • issue: #4117 -> PR: #4123

I have removed all custom rules to make sure it is not connected to them, without any success.

Complete output when running SwiftLint, including the stack trace and command used
$ `swiftlint lint --reporter markdown --output linter_result.md --config ./.swiftlint.yml
...
Linting 'SomeSwiftFile.swift' (5897/5897)
Environment
  • SwiftLint version (run swiftlint version to be sure)? swiftlint_linux: 0.50.3 / swiftlint_docker: 0.50.3 / macos: 0.50.3

  • Installation method used (Homebrew, CocoaPods, building from source, etc)? via github download / docker

  • Paste your configuration file: irrelevant since it is running fine on macOS and I have exluded it from the command, but still the issue persists

  • Are you using nested configurations? NO
    If so, paste their relative paths and respective contents.

  • Which Xcode version are you using (check xcodebuild -version)? 14.2 swift 5.7

  • Do you have a sample that shows the issue? Run echo "[string here]" | swiftlint lint --no-cache --use-stdin --enable-all-rules
    to quickly test if your example is really demonstrating the issue. If your example is more
    complex, you can use swiftlint lint --path [file here] --no-cache --enable-all-rules.

Research direction

Start by reproducing swiftlint lint --reporter markdown --output linter_result.md --config ./.swiftlint.yml with SwiftLint 0.50.3 on Linux or Docker, then compare it with the command restricted to changed files. Done means a full scan terminates on Linux and Docker and writes linter_result.md without requiring custom rules.
