About Me

Hello! I'm Partha Protim Paul, a Software Engineer currently pursuing my Master's in Computer Science under the supervision of Prof. Reid Holmes at UBC in Vancouver. I have hands-on experience of 4 years in designing and developing robust backend systems, with a focus on Domain Driven Development and microservices architecture. I'm also keen on staying up-to-date with the latest technologies and applying them to build innovative and impactful products.

I have contributed to open-source projects like Apache Commons Collections and Automerge. I am always eager to learn and contribute to the software development community.

Open Source Contributions

apache/commons-collections

Fix flaky test occurred in 'CollectionBagTest.testCollectionToArray2'

  • Purpose of this PR: This PR fixes the flaky test org.apache.commons.collections4.bag.CollectionBagTest.testCollectionToArray2
  • Why the test fails: As the CollectionBagTest uses HashBag as its collection which uses HashMap internally and as per Java 8 documentation, the ordering of HashMap is not constant, so assigning the same hashmap as an array to different objects can change the ordering. So when comparing these two arrays with assertEquals the test may fail as their ordering can be different.
  • Fix: Override the getIterationBehaviour()' method from AbstractCollectionTestand returnUNORDEREDinCollectionBagTest.

Automerge

add toString() method to RawString object

  • Description: This PR adds a toString() method to the RawString class. This makes it easier to uniformly handle string and RawString in code, as you can simply call toString() on any value of either type and get a string representation of it.

  • Fix: Create a HashSet from both arrays named a and array and check if they both are equal in testCollectionToArray2
