Naming conventions for threads?

Question

It\'s helpful to name threads so one can sort out which threads are doing what for diagnostic and debugging purposes.

Is there a particular naming convention for thr

Answer 1

There's to my knowledge no standard. Over the time I've found these guidelines to be helpful:

• Use short names because they don't make the lines in a log file too long.

• Create names where the important part is at the beginning. Log viewers in a graphical user interface tend to have tables with columns, and the thread column is usually small or will be made small by you to read everything else.

• Do not use the word "thread" in the thread name because it is obvious.

• make the thread names easily grep-able. Avoid similar sounding thread names

• if you have several threads of the same nature, enumerate them with IDs that are unique to one execution of the application or one log file, whichever fits your logging habits.

• avoid generalizations like "WorkerThread" (how do you name the next 5 worker threads?), "GUIThread" (which GUI? is it for one window? for everything?) or "Calculation" (what does it calculate?).

• if you have a test group that uses thread names to grep your application's log files, do not rename your threads after some time. Your testers will hate you for doing so. Thread names in well-tested applications should be there to stay.

• when you have threads that service a network connection, try to include the target network address in the thread name (e.g. channel_123.212.123.3). Don't forget about enumeration though if there are multiple connections to the same host.

If you have many threads and forgot to name one, your log mechanism should output a unique thread ID instead (API-specific, e.g. by calling pthread_self() )
