Project Report: "Gotta Catch 'Em All" - Leveraging Coverity for RGW Code Cleanup in Ceph

The "Gotta Catch 'Em All" project focused on leveraging the Coverity static analysis tool to enhance the code quality of the Ceph RGW (Rados Gateway) module. We addressed a range of issues and categorized them based on severity and relevance. We aim to use this data to evaluate the potential of Coverity for the Ceph organization.

Data

A total of 87 issues were fixed as part of the GSoC, and they were categorized into four main categories based on severity:

• Critical: 36 issues
• Not Worth Effort: 6 issues
• Nice to Have: 10 issues
• False Positive: 35 issues

Goal

This is list TODOs for the bucket notification PR in Rook. Based on these comments:

• rook/rook#8426 (comment)
• rook/rook#8426 (review)

Priority 1

Refactoring and Unit Tests

• code reuse with reused function (and unit test for above reused function)
• use the regular S3 agent for notification provisioning (topic will still need the special SNS client)

yuvalif

Running Tests Locally

• you run the tests locally from your "build" directory in your test environment
• then you need to add a "test_multi.conf" file:

[DEFAULT]
num_zonegroups=1
num_zones=1
num_ps_zones=0
gateways_per_zone=1

Run the following in the terminal:

Install the gcc-7 packages:

sudo apt-get install -y software-properties-common
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
