bug: application desync and data lost when running more than 1 instance of CareerSync #5

Open wxiaoyun opened 3 months ago

wxiaoyun commented 3 months ago

Description

When running more than 1 instance of CareerSync (running the app from 2 terminal sessions), can cause the app data to de-synchronized and lost.
As an experience command line user, it is normal to have multiple terminal windows open or tmux windows. It is possible that a user can accidentally open 2 instances of the app.

Steps to reproduce

Open 2 terminal session and each run java -jar <jar_file>
On each instance of the app, run any valid add command
One of the internships added will potentially not be saved

Expected

Both internship entry should be saved

Actual

Some internship entry data is lost

Potential Suggestions

Add warning message when more than 1 instance of the app is launched

Screenshots

nil, lost of data

Team's Response

Based on this constraint, this bug only occurs when this TP constraint is violated, since realistically this likely simulates a situation where multiple users are using the app to edit the same data file. Thus, this is rejected
