Enhancement: Resume Support, Retry Logic, and Timestamped Logging for fetch_databus_assest.sh

[spyke7]

Hey team! 👋

I’ve been working on an enhanced version of our fetch_databus_assest.sh script and wanted to propose some neat new features that make downloads more robust and logging more informative. Here’s what’s new in fetch_databus_assest.sh compared to the previous version:

New Features

1. Resume support for interrupted downloads

• --resume flag allows downloads to resume from where they left off.

• Works for both Vault and non-Vault downloads.

• Helpful for large artifacts or flaky network conditions.

2. Retry logic for non-Vault downloads

• --retry-count N lets users specify how many times a file should be retried if a download fails (default: 3).

• Retry attempts include brief delays and helpful logs.

3. Improved logging with timestamps

• Added log_timestamp and log_info helpers.

• All info logs now include timestamps for easier debugging and tracking progress.

These are minor CLI updates

Updated usage message to include the new flags.

Debug and dry-run behavior remain unchanged.

These changes should make the script more resilient in real-world scenarios, especially when fetching large or multiple files. The new flags are fully optional, so existing workflows aren’t broken.

Would love to get a PR review and check this in so everyone can benefit from smoother downloads!
