| # DO NOT add landmines as part of a regular CL. Landmines are a last-effort |
| # bandaid fix if a CL that got landed has a build dependency bug and all bots |
| # need to be cleaned up. If you're writing a new CL that causes build |
| # dependency problems, fix the dependency problems instead of adding a |
| # landmine. |
| # |
| # Before adding or changing a landmine consider the consequences of doing so. |
| # Doing so will wipe out every output directory on every Chrome developer's |
| # machine. This can be particularly problematic on Windows where the directory |
| # deletion may well fail (locked files, command prompt in the directory, |
| # etc.), and generated .sln and .vcxproj files will be deleted. |
| # |
| # This output directory deletion will be repeated when going back and forth |
| # across the change that added the landmine, adding to the cost. There are |
| # usually less troublesome alternatives. |
