Add appimage packaging #225
Conversation
WalkthroughThe project has evolved to enhance its Linux distribution capabilities. It now includes an AppImage packaging option, alongside the existing Debian package format. The workflow has been updated to handle the new packaging process, and necessary files for AppImage support, such as the application runner and desktop entry, have been added. The script to package the AppImage has also been introduced, streamlining the build process for this portable format. Changes

- 1-26: The script
package-appimage.shfollows the standard practices for creating an AppImage, including setting up necessary files, usingjpackage, and copying resources. The steps are clear and maintainable..github/workflows/main.yml (1)
- 228-268: > Note: This review was outside the patches, so it was mapped to the patch with the greatest overlap. Original lines [205-267]
The changes to the CI workflow are well-structured and clear. The separation of jobs for Debian (
package-linux-deb) and AppImage (package-linux-appimage) packaging is a good practice. The steps for building the AppImage, including setting up dependencies and renaming the output file to include the version, are correctly implemented.

1-1: Ensure the shebang line is using a portable path to
sh.2-2: Verify that
readlink -fis the best choice for portability across different Linux distributions as some may not support it.4-4: Appending to the
PATHvariable without prior sanitization may pose a security risk. Ensure that the directories being added are secure.Verification successful
Based on the output from the executed scripts, we have the following information regarding the directories added to the
PATHvariable in theAppRunscript:
- The directory
build/OwlPlug.AppDir/usr/bin/exists and has the permissionsdrwxr-xr-x. This indicates that it is a directory (d), readable (r), writable (w), and executable (x) by the owner (presumably the creator of the AppImage), readable and executable by the group, and readable and executable by others.- The directories
build/OwlPlug.AppDir/usr/sbin/,build/OwlPlug.AppDir/usr/games/,build/OwlPlug.AppDir/bin/, andbuild/OwlPlug.AppDir/sbin/do not exist in the repository.Given this information, the following points can be made:
- The existing directory
usr/bin/within the AppImage build directory has standard permissions that do not pose an immediate security risk based on the output provided. It is not writable by group or others, which is a good security practice.- The other directories do not exist in the repository, so they do not pose a security risk in the context of this repository. However, if these directories were to be created during the AppImage build process or at runtime, their permissions would need to be verified to ensure they are secure.
In conclusion, the only directory we can verify (
usr/bin/) is set with permissions that are typical and do not indicate a security risk. For the other directories, since they do not exist in the repository, we cannot assess their security. If these directories are meant to be created during the AppImage build or execution, it would be necessary to ensure that their permissions are set securely at that time.* 6-6: Confirm that the executable referenced by `EXEC` is intended to be run with any passed arguments (`"$@"`).Scripts Executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Verify that the directories added to PATH are secure and intended fd --exec ls -ld {} +Length of output: 71371
Script:
#!/bin/bash # List the permissions of the directories within build/OwlPlug.AppDir that correspond to the ones added to the PATH variable in the AppRun script. ls -ld build/OwlPlug.AppDir/usr/bin/ ls -ld build/OwlPlug.AppDir/usr/sbin/ ls -ld build/OwlPlug.AppDir/usr/games/ ls -ld build/OwlPlug.AppDir/bin/ ls -ld build/OwlPlug.AppDir/sbin/Length of output: 561
Verification successful
The content of the
AppRunfile has been successfully retrieved, and it includes the line:exec "${EXEC}" "$@"This confirms that the script is designed to execute the command referenced by the
EXECvariable with any arguments passed to the script ("$@"). Therefore, the review comment asking to confirm that the executable referenced byEXECis intended to be run with any passed arguments has been verified.
- The
EXECvariable is set by searching for an 'Exec=' entry in a.desktopfile within the same directory.- The
execcommand then uses this variable to run the specified executable, passing all arguments received by the script.Scripts Executed
The following scripts were executed for the analysis:

build/package-appimage.sh (3)
- 7-7: Verify that the relative path used in
cpis correct and that theLICENSEfile exists at the expected location.Verification successful
The output from the shell script indicates that a
LICENSEfile does exist at the root of the repository. Given that thecpcommand in thebuild/package-appimage.shscript uses a relative path from the script's location, we need to verify that the script's directory is one level deep from the root (i.e.,build/) to ensure that the../LICENSEpath is correct.To confirm the script's location, we can use the
fdcommand to find thepackage-appimage.shscript and then infer its directory structure from the output.
The output confirms that the
package-appimage.shscript is located in thebuild/directory. Since theLICENSEfile is at the root of the repository, the relative path../LICENSEused in thecpcommand within thepackage-appimage.shscript is indeed correct. The script is in thebuild/directory, so../would navigate one directory up to the root where theLICENSEfile is located.Based on this information, the relative path used in the
cpcommand is correct, and theLICENSEfile exists at the expected location.* 11-11: Check for the existence of the source jar file before attempting to copy it to prevent runtime errors.Scripts Executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Check if the LICENSE file exists in the expected directory fd LICENSELength of output: 20

#!/bin/bash # Find the location of the package-appimage.sh script fd package-appimage.shLength of output: 50
- 15-17: Ensure that
jpackageis used correctly and that all the options provided are valid and necessary..github/workflows/main.yml (4)
181-181: The artifact name change for the Windows installer is consistent with the other changes and follows a clear naming convention.
206-206: The artifact name change for the macOS installer is consistent with the other changes and follows a clear naming convention.
231-231: The artifact name change for the Linux installer is consistent with the other changes and follows a clear naming convention.
233-267: The addition of the
package-linux-appimagejob is consistent with the PR objectives. Ensure that all steps are necessary and that the use ofsudois justified and secure.Verification successful
Based on the provided output, the
package-linux-appimagejob in the.github/workflows/main.ymlfile includes the following steps:
- Checkout the repository.
- Set up JDK 17.
- Get the version of the project.
- Install the Jar artifact.
- Package the installer using the
package-appimage.shscript.- Download the FUSE dependency.
- Download the AppImage Tool.
- Allow execution of the AppImage Tool.
- Run the AppImage Tool to create the AppImage.
- Rename the OwlPlug AppImage.
- Upload the Installer Artifact.
Each step in the job appears to be necessary for the AppImage packaging process:
- Steps 1-4 are standard setup steps for a build job.
- Step 5 packages the installer, which is the main objective of the job.
- Steps 6-9 are specific to the creation of an AppImage, which requires the FUSE library and the AppImage Tool.
- Step 10 renames the AppImage for clarity and versioning.
- Step 11 uploads the artifact, which is the final output of the job.
The use of
sudoin step 6 is justified as it is required to install system packages on Ubuntu, and it is a common practice in CI/CD environments to use elevated privileges for such tasks. However, it is always recommended to ensure that the commands executed withsudoare from trusted sources and do not pose security risks.Scripts Executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Verify the necessity of each step in the package-linux-appimage job rg --type yaml 'package-linux-appimage'Length of output: 188
