Isn't it better to play your favorite game than to catch bugs? File System Monitor saves hours of debugging

When gaming plans meet urgent bugs: How AppSpector's file system monitor saved the day

It was 5 PM, and with only one hour left before the end of the workday, Lisa, a mobile app developer and avid gamer, eagerly anticipated an intense Counter-Strike session with his friends. She had just purchased a new skin for his in-game knife and couldn't wait to showcase it.

As she was about to shut down her computer, her project manager alerted her to an urgent issue: the app was crashing on the client's side, and they needed a fix immediately.

The unexpected file system dilemma

Lisa quickly dove into the problem. The app, a document management tool, was experiencing crashes whenever users attempted to upload files. Initial logs were unhelpful, and traditional software bug tracking software didn't reveal any obvious issues. She suspected that the problem lay within the app's file management system.

Upon closer examination, she theorized that the app was not correctly handling temporary files during the upload process. Specifically, the app created temporary files in the device's file system but failed to delete them after the upload was complete. Over time, these orphaned files consumed storage space, leading to crashes when the app tried to allocate more space than was available.

Moreover, the app was supposed to move uploaded files from a temporary directory to a permanent storage location. Lisa noticed that under certain network conditions, the file transfer was interrupted, leaving behind incomplete files that were neither retried nor cleaned up. This inconsistency was difficult to reproduce and required real-time monitoring of the file system.

Leveraging AppSpector's file system monitor

Facing a tight deadline and not wanting to miss her gaming session, Lisa turned to AppSpector's file system monitor. This powerful file monitoring system allowed her to remotely navigate the app's file structure, including the app bundle itself. With read/write access, she could examine existing files and observe in real-time how the app interacted with the file system.

Using this advanced system management tool, Lisa discovered that the temporary files were indeed not being deleted. She was able to download the problematic files directly from the device and analyze them. The filenames and metadata indicated that the cleanup function was not being called due to an exception in the file handling logic when certain file types were uploaded.

She pinpointed that when users uploaded files with special characters in the filename, the app's path normalization function failed, causing the file move operation to throw an exception. Since the exception wasn't properly handled, the cleanup code that followed was never executed, leaving temporary files behind.

By modifying the code to properly sanitize filenames and adding exception handling to ensure the cleanup function was always executed, Lisa implemented a fix. She tested the solution remotely using AppSpector, verifying that temporary files were now being deleted as expected and that the app no longer crashed during file uploads.
