What did I do this week?

After completing tests and features for mscolab's project window and getting the PR merged, I started working on a more tricky part of the project. Introducing version control to mscolab server's storage. As explained on the previous blog, this is done to introduce some features to project. Mainly the following

  1. undo/redo a particular change(commit) - TO BE IMPLEMENTED
  2. checkout to a particular commit - IMPLEMENTED

I used 'gitpython' library to handle git related functionalities. For now, the commit hash is stored in 'Change' model. It might seem like it's redundant, which is true, but we'll work on this later to find a way to store every detail in the commit, to scrap the 'Change' model.

What's coming up next?

The aforementioned features are already implemented, I have to write tests before I make a PR. Once the PR is created, I will parallelly start working on GUI to create projects, users, and displaying user and project details in project window. After this, my mentor has planned a testing of added features in development server.

Did I get stuck anywhere?

There were two major places where I got stuck.

  1. While introducing version control to file storage,  git commit would not work if this file is opened in 'w'(write mode) in any part of program. I had to close the opened reference, so the most recent changes are committed.
  2. I couldn't find a reason to why this happened, but while opening a 'question' with PyQt's MessageBox in an event handler of QListWidgetItem's activate event, it opens multiple times if the 'QListWidget' is reloaded. Maybe because if an item is activated, and another item is added to the list in the event handler, the new item in that index is activated again, in a loop. I avoided it by setting an 'active_change_id' to keep track of the activated item's id and then manually asking an user to press a button to checkout to that change.
