I’ve been working on a WebSocket application and encountered a peculiar issue where state variables were randomly changing. To tackle this, I encapsulated the state variable into getter and setter methods, adding some humor to prevent accidental changes. Here’s how my methods looked:
java
void setReceivedPongToFalse() {
if (enableLogging) log.debug “setReceivedPongToFalse()”
state.elephant = “FALSE STRING”
if (enableLogging) log.debug “receivedPong set to: ${state.elephant}”
}
void setReceivedPongToTrue() {
if (enableLogging) log.debug “setReceivedPongToTrue()”
state.elephant = “TRUE STRING”
if (enableLogging) log.debug “receivedPong set to: ${state.elephant}”
}
boolean getReceivedPong() {
if (enableLogging) log.debug “getReceivedPong(): ${state.elephant}”
return state.elephant == “TRUE STRING”
}
Despite these precautions, the variable occasionally flipped from true to false without any apparent cause. My initial suspicion was a race condition during event processing. To address this, I explored thread-safe methods for state modification. After some research, I implemented synchronized methods and ensured proper serialization of state changes.
Through meticulous logging, I discovered that external events were triggering unintended state modifications. This led me to implement additional safeguards, such as using atomic variables and ensuring all state changes were properly synchronized.
If anyone else is facing similar issues, I recommend checking for race conditions, ensuring thread safety, and thoroughly logging state changes. It’s a fascinating challenge, and I’m eager to hear how others have tackled this problem!
