of Code (<a href="http://g.co/gsoc">g.co/gsoc</a>) is Google's mentorship program for bringing new contributors into open source communities.Google Summer of Code is a unique program where new contributors to open source, ages 18 and over, are paired with a mentor to introduce them to the open source community and provide guidance while they work on a real world open source project over the summer. Projects cover a wide range of fields including: Cloud, Operating Systems, Graphics, Medicine, Programming Languages, Robotics, Science, Security and many more. GSoC Contributors do earn a stipend to work on their small, (~90 hour), medium (~175 hour) or large (~350 hour) projects.GSoC is a highly competitive program, so don't wait to the last minute to prepare! GSoC Contributors should reach out to the mentors of projects that interest them once orgs are announced on February 27, 2025. Potential GSoC Contributors can apply for Ceph's projects at <a href="http://g.co/gsoc">g.co/gsoc</a> from March 24th - April 8, 2025.See the list of projects we have available for GSoC contributors and <a href="https://ceph.io/en/developers/contribute/">learn how get started with contributions</a>.For any questions, contact Vallari Agrawal (<a href="mailto:vallari.agrawal@ibm.com">vallari.agrawal@ibm.com</a>).<hr class="hr"><h2 id="teuthology-on-podman">Teuthology on Podman <a class="link-anchor" href="#teuthology-on-podman">¶</a></h2>Mentor name(s): Zack Cerza, Kamoltat (Junior) Sirivadhna Aishwarya Mathuria, Vallari AgrawalMentor email(s): <a href="mailto:zack1@ibm.com">zack1@ibm.com</a>, <a href="mailto:ksirivad@ibm.com">ksirivad@ibm.com</a>, <a href="mailto:aishwarya.mathuria@ibm.com">aishwarya.mathuria@ibm.com</a>, <a href="mailto:vallari.agrawal@ibm.com">vallari.agrawal@ibm.com</a>Difficulty: HardProject Hours: 175Skills needed: python, containerisation, linuxSubcomponent of Ceph: <a href="https://github.com/ceph/teuthology">Ceph Integration Test Framework</a>Description of project:<a href="https://github.com/zmc/ceph-devstack">ceph-devstack</a> is an in-development tool that uses rootless podman containers to deploy a scaled-down teuthology lab. It has proven useful for testing changes to teuthology and its related services, allowing us to more easily and flexibly make changes to components without worrying about causing outages.It has some basic ability to run Ceph tests, but could benefit significantly from more investment in that area.Improve and extend ceph-devstack's ability to perform teuthology tests against Ceph builds.

It leverages a runtime file named drivedb.h that directs what attributes are to be found with what numeric IDs, and how to interpret them. drivedb.h is a mess, and upstream smartmontools would likely resist wholesale refactoring. For example, SSD wear might be labeled as "lifetime remaining" or "wear level" or multiple other strings. Some devices also report wear used, others wear remaining.One task would be to add an interpretation primitive to the c++ code so that a drivedb.h entry can specify that the result should be subtracted from 100. The larger task would be to write a postprocessor for drivedb.h that more or less is a sequence of regex invocations that converges the existing freeform attribute label names into a normalized, defined set. Many tools just pass through the text labels, so doing meaningful analysis or queries is difficult; often only a fraction of the data is actually captured as a result. The output also includes numeric attribute IDs, which are less varied, but relying on them instead of the text labels is fraught because these numeric IDs are not strictly standardized either. I have seen drives that report a metric on a different numeric ID than most others, and/or that report a different metric on a specific numeric than most others report on that ID.For extra credit, interface with the central telemetry DB as described in project "Public telemetry slice/dice of SMART data".Standup/weekly call mentee could attend?: TBDSteps to evaluate an applicant for the project: Ability to leverage code libraries and write the glue code.1-2 short paragraphs about what first 2 weeks of work would look like during the internship: TBD<hr class="hr"><h2 id="the-more-the-merrier">The More The Merrier <a class="link-anchor" href="#the-more-the-merrier">¶</a></h2>Mentor name(s): Yuval LifshitzMentor email(s): <a href="mailto:ylifshit@ibm.com">ylifshit@ibm.com</a>Difficulty: HardProject Hours: 350Skills needed: C++, PythonSubcomponent of Ceph: RGWDescription of project:Detailed description of the project and evalution steps can be found <a href="https://gist.github.com/yuvalif/9c5a1ed326ca14cf4851d7a0b8ba0db8">here</a>.Persistent bucket notifications are a very useful and powerful featuretech talk: <a href="https://www.youtube.com/watch?v=57Ejl6R-L20">https://www.youtube.com/watch?v=57Ejl6R-L20</a>usecase example: <a href="https://www.youtube.com/watch?v=57Ejl6R-L20">https://www.youtube.com/watch?v=57Ejl6R-L20</a>However, they can pose a performance issue, since the notifications regarding a specific bucket are written to a single RADOS queue (unlike the writes to the bucket which are distributed across multiple bucket shards. So, in case that small objects are written to the bucket, the overhead of the notifications is considerable.
