Satish Duggana updated ATLAS-1014:
----------------------------------
Description:
{code:java}
public static RequestContext get() {
if (CURRENT_CONTEXT.get() == null) {
synchronized (RequestContext.class) {
if (CURRENT_CONTEXT.get() == null) {
createContext();
}
}
}
return CURRENT_CONTEXT.get();
}
{code}
There is no need to have double checked locking and synchronization for setting
a threadlocal state. That logic can be removed by adding the below code while
instantiating CURRENT_CONTEXT.
{code:java}
private static final ThreadLocal<RequestContext> CURRENT_CONTEXT = new
ThreadLocal<RequestContext>() {
@Override
protected RequestContext initialValue() {
RequestContext context = new RequestContext();
context.requestTime = System.currentTimeMillis();
return context;
}
};
{code}
RequestContext#createContext usages can be changed to RequestContext#get
was:
public static RequestContext get() {
if (CURRENT_CONTEXT.get() == null) {
synchronized (RequestContext.class) {
if (CURRENT_CONTEXT.get() == null) {
createContext();
}
}
}
return CURRENT_CONTEXT.get();
}
There is no need to have double checked locking and synchronization for setting
current thread's state. That logic can be removed by adding the below code
while instantiating CURRENT_CONTEXT.
``` java
private static final ThreadLocal<RequestContext> CURRENT_CONTEXT = new
ThreadLocal<RequestContext>() {
@Override
protected RequestContext initialValue() {
RequestContext context = new RequestContext();
context.requestTime = System.currentTimeMillis();
return context;
}
};
```
RequestContext#createContext usages can be changed to RequestContext#get
> Unnecessary locking and double checked locking for a threadlocal in
> RequestContext.
