Summary by CodeRabbit

  • New Features
    • Added a --runtime-file option to select the AppImage runtime to embed.
    • Runtime lookup now checks additional lib64 and usr/lib64 locations.
  • Bug Fixes
    • Runtime selection now follows a consistent order, making the chosen runtime predictable.
    • When a runtime cannot be found, error messages identify the missing file or list the locations checked.

📝 Walkthrough

Walkthrough

The release workflow now runs on pushes to release. Runtime selection now sorts loader paths, supports an explicit runtime file, and searches ordered candidate paths when no runtime is specified.

Changes

Runtime Selection

Layer / File(s) Summary
Deterministic loader selection
data/apprun.sh
The script sorts matching loader paths before selecting one.
Builder runtime selection and override
src/appimagebuilder_main.cpp, src/appimagebuilder.cpp, src/appimagebuilder.h
The command accepts --runtime-file. When no path is supplied, the builder searches ordered runtime candidates and reports searched paths if none exists. The lookup documentation includes lib64 and usr/lib64.

Release Workflow Trigger

A symlinked builder can embed the wrong runtime in an AppImage. Correct runtime selection before merging; also make loader selection reproducible across locales.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Fix the sort locale so loader selection stays reproducible.

When the AppImage contains multiple matches, different LC_COLLATE settings can change which path head -n 1 selects. GNU sort uses the active locale’s collation sequence. (gnu.org) Set a fixed locale for this pipeline.

Suggested fix
-LD_LINUX=$(find "${ROOT}" -name 'ld-*.so.*' | sort | head -n 1)
+LD_LINUX=$(find "${ROOT}" -name 'ld-*.so.*' | LC_ALL=C sort | head -n 1)

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Resolve the executable symlink before searching for the bundled runtime.

If /usr/local/bin/appimagebuilder links to /opt/app/usr/bin/appimagebuilder, this code searches /usr/local/share/AppImageKit/runtime first. If that directory contains a runtime for arch, Build embeds it before checking the actual installation. Derive executable_dir from the canonical executable path so a symlink cannot select an unrelated runtime. absolutePath() does not resolve symbolic links, and cleanPath() does not fix that distinction.
