But unless I am missing something, 063 does not use common.qemu... (I'll send a v3 with 156) -Jeff

Good point. 063 does litter, even on success, however: $ rm -rf scratch/ $ ./check -raw 063 ... $ ls scratch/ t.raw.raw1 One idea presented in an earlier thread was that common.rc should create a subdirectory per test (rather than all tests sharing scratch/), and then common.rc itself install the cleanup hook that wipes out the entire subdirectory (or maybe even add a command-line option to ./check to suppress wiping when it is desirable to debug a test failure by seeing the droppings left behind).

I'll leave that for another series though; there are a few other changes based on some suggestions from Daniel that I'd like to implement as well, and I can fold your suggestions above into a new series (unless someone else does it first). -Jeff

Sounds good, I was thinking about making ./check run tests in parallel. If each test has its own tmpdir, it will be much easier. Fam

(I have a script that basically does TEST_DIR=/tmp/test-$1 ./check -$1) Max

This would make the scripts simpler to read and implement, and less prone to do Bad Things. (I keep waiting for some iotest script to misquote a var during cleanup and do an rm -f ~/* or something... it'd be nice to not have to worry about that). -Jeff

I just wanted to throw in that it isn't completely impossible to run iotests in parallel, at least for different formats. (Baking it in would also mean that we could automatically distribute test invocations for a single format to multiple instances, yes (as in your ./check -j5 proposal). But that's work to do. :-)) Max
