Several changes are coming to IntegrityChecker (part of diglloydTools), but only the Java version, which is cross-platform (any OS that can run Java).

All users are encouraged to migrate to the Java version of IntegrityChecker. The native version will not be carried forward into macOS Catalina.

Get diglloydTools.

For IntegrityChecker java (icj) only...

Better file modification date verification

MacOS has a bug that truncate the file modification date/time. The issue becomes a noisy hassle when verifying files (warnings about changed file dates ). In IntegrityChecker java (icj), the following behavior will occur:

• At present (before I publish the updated version), icj does not warn about the file dates because it only records the file modification date to the second.
• Going forward, icj will record the file modification date to the millisecond, but how it is used will vary.
• The file modification date will be compared to the millisecond if and only if both the actual file modification date has non-zero milliseconds, and the recorded file modification date in the hash file also has non-zero milliseconds. Otherwise, milliseconds are ignored. In this way, files that have non-zero millis will be strictly compared, which will be the case for the same type of file system, e.g., the original volume or a backup using the same file system.

Tracking of folders with no files, subfolders gone missing

IntegrityChecker has always been file-based—no files meant no hashing. This left open one ugly possibility which I rant into myself once: some kind of copying or backup error that prunes off folders.

The change will that now icj will record all subfolder names within a folder, whether or not there are also files in that folder. Warnings will be issued when subfolders go missing.

Summary of subfolder changes:
/Volumes/Scratch/test/junk/a/aa subfolders missing:
{2019-0704-TripPictures, 2019-0714-Birthday}
End summary of subfolder changes.

Better status and logging and summary results

The goal is an HTML summary report with appropriate linking and formatting to make the results more approachable and understandable. Possibly it will be updated in real-time as the operation progresses. This feature may start simple and then improve steadily.

GUI

A Java GUI may become available.
