Chapter 2 Coding Guidelines

This section shows the guidelines that MySQL's developers follow when writing new code. Consistent style is important for us, because everyone must know what to expect. For example, after we become accustomed to seeing that everything inside an if is indented two spaces, we can glance at a listing and understand what's nested within what. Writing non-conforming code can be bad. For example, if we want to find where assignments are made to variable mutex_count, we might search for mutex_count with an editor and miss assignments that look like mutex_count = with a space before the equal sign (which is non-conforming). Knowing our rules, you'll find it easier to read our code, and when you decide to contribute (which we hope you'll consider!) we'll find it easier to read and review your code.
