One of the biggest causes of buildfarm run failures is "out of disk space". That's not just because people are running buildfarm critters on small slow machines; it's because "make check-world" is an enormous space hog. Some numbers from current HEAD:clean source tree: 120MB built source tree: 400MB tree after make check-world: 3GB (This is excluding ~250MB for one's git repo.) The reason for all the bloat is the temporary install trees that we create, which tend to eat up about 100MB apiece, and there are dozens of them (eg, one per testable contrib module). Those don't get removed until the end of the test run, so the usage is cumulative. The attached proposed patch removes each temp install tree as soon as we're done with it, in the normal case where no error was detected. This brings the peak space usage down from ~3GB to ~750MB. To make things better in the buildfarm, we'd have to back-patch this into all active branches, but I don't see any big problem with doing so. Any objections?
I don't have an issue, but you should be aware that the buildfarm doesn't in fact run "make check-world", and it doesn't to a test install for each contrib module, since it runs "installcheck", not "check" for those. It also cleans up some data directories as it goes.
