[kepler-dev] Bugs vs. Features

Below is just my opinion, but I thought it would be useful to
discuss this so that we are all on the same page.
When adding something to bugzilla, it is useful to differentiate
between bugs and enhancements.
In my mind, a bug is problem with the current set of features.
- Crash or stack trace
- Incorrect results
- Documentation does not match reality
- Can't do something obvious
An enhancement is missing functionality.
- Demo idea
- Need a new actor that does xxx
- "It would be nice if . . ."
The reason to differentiate between the two is that bugs
should usually be handled before enhancements
The issue is that it can be hard to differentiate between
bugs and enhancements. I usually use the litmus test of
is the issue "wrong"? If it is wrong, then it is a bug.
If the issue is "missing", then it is an enhancement.
One person's bug is another person's enhancement.
I'll sometimes use the term RFE for Request For Enhancement.
Bugzilla has these fields under severity:
Blocker Blocks development and/or testing work
Critical crashes, loss of data, severe memory leak
Major major loss of function
Minor minor loss of function, or other problem where easy
workaround is present
Trivial cosmetic problem like misspelled words or misaligned text
Enhancement Request for enhancement
There are also priorities, where P1 is the most important.
There is a social issue where when someone adds an issue to bugzilla,
and someone else changes the classification, there can be hurt
feelings because of the "one person's bug is another person's
