| [cdt-debug-dev] Collect more thread information - About "info thread" output ? |
Hi,
We have a problem to
retrieve the thread information based on current CDT3.1. For our system, we
want to know the underlying thread ID and other thread information when user
selects an IThread in the Debug view (or LaunchView). However, there is no way
through the API to retrieve such information (let me know if there is one :-)).
The current
org.eclipse.cdt.debug.mi.core.output.CLIInfoThreadsInfo only keeps the thread
id assigned by GDB. For example:
The info thread command for
a standard GDB will return the following output for pthread:
3 Thread -1217840208 (LWP 23518) 0xb7f6c17c in clone () from
/lib/tls/libc.so.6
* 2 Thread -1209451600 (LWP
23517) do_nothing (null=0x0) at
pthread_Test.c:12
1 Thread -1208182528 (LWP 23514) 0xb7f6c17c in clone () from
/lib/tls/libc.so.6
For our system, our GDB will
return the following output for a thread:
6 Thread 121 (state=STOP, ID=0x0000100,
name="THREAD No.1", priority=211)
CLIInfoThreadInfo only keeps the id (the first digit of above output lines). All the information besides the thread id will be also useful to us. However, we could not find a way to access the output by using current API.
Here is our solution:
- Add a String[] to the CLIInfoThreadsInfo
class:
class CLIInfiThreadsInfo{
protected String[] infos;
public String[] getThreadInfos(){
return infos;
}
}
The infos[] will be sorted together with
threadIds[].
- Change the
org.eclispe.cdt.debug.mi.core.cdi.model.Thread constructor:
class Thread{
protected String info;
public String getThreadInfo(){
return info;
}
public Thread(Target target, int
threadId, String info) implements ICDIThread{
this(target, threadId, null, info);
}
public Thread(Target target, int
threadId, String threadName, String threadInfo){
super(target);
id=threadId;
name=threadName;
info = threadInfo;
}
}
And refactor the caller of Thread (only few places in mi.core package need change).
- Add an adapter factory to the CThread.class,
so that it can return an ICDIThread when user select IThread in Debug view. This is done in the org.eclipse.cdt.debug.internal.core.model package.
I think the above change does not break the other modules. I am not sure if this is a good solution or not. If is there any other solution available without changing the CDT
code, please let me know. If above changes make sense, I can send you a
patch.
Thanks
