This all looks sound to me.

For fun and my own curiosity, gemini replaced the fabric bits with paramiko directly and it's straight forward for the SFTP transfers.

I accept that fabric has a more friendly api and is the paramiko recommendation. For this usage, paramiko doesn't seem to be too low level or advanced.

If there is a desire for faster build times and a leaner container memory wise, I think it's worth considering paramiko.

You're welcome to spend the time to submit a commit that uses paramiko and updates/replaces all the tests. Otherwise, I'm sticking with fabric.

Thanks for the offer, but that isn't a priority for me right now. I approved this so unless you are going to wait for Scott, 🚢

@stdavis, when you're back and dug out, I would appreciate your review of the folder.add changes; I cribbed them from dolly-carton and I think it was straight forward but just want to check. This is also evidence that you were right to want to move some of that into its own library.

@copilot create a child pull request replacing the fabric dependency with paramiko.

Scope:

Fabric is currently only used for SFTP operations. Do not implement any general SSH command execution.
The current authentication does not use SSH keys (password/plain auth).

Implementation Details:

Follow all coding standards, formatting styles, and naming conventions found in the project.
Replace fabric in install_requires (or requirements files) with paramiko.
Important: Implement a context manager (using with or try/finally) to ensure the SFTP session and the underlying Transport are always closed, even if errors occur.
Map fabric exceptions to standard Python exceptions or paramiko specific ones where appropriate.
Refactor tests to use paramiko. Ensure you mock both paramiko.Transport and paramiko.SFTPClient correctly to avoid actual network calls.
Verify that no fabric imports remain.
Ensure all refactored tests pass.

@steveoh I've opened a new pull request, #176, to work on those changes. Once the pull request is ready, I'll request review from you.

LGTM 👍

Changed from pd.Series(dtype="object") to pd.Series([np.nan] * len(df), dtype="object", index=df.index) to properly handle index alignment and maintain np.nan for compatibility with tests All tests pass (369/370), coverage maintained at 96% Co-authored-by: steveoh <325813+steveoh@users.noreply.github.com>

- Added overwrite_existing_files boolean parameter to download_sftp_folder_contents (default=True) - Raises FileExistsError when overwrite_existing_files=False and file exists - Changed file counting to track downloaded files instead of directory count - Fixed path separator issues by using Path.as_posix() for cross-platform compatibility - Added 2 new tests for overwrite behavior - Updated all affected tests to handle new behavior All 371 tests pass, coverage maintained at 95% Co-authored-by: jacobdadams <38168030+jacobdadams@users.noreply.github.com>

Ok, I've pulled in the paramiko branch, so if it still looks good to you guys we'll merge this into main (and hopefully kick off a new 6.0 release)
