Regarding testing: the best thing to do IMHO is to explain in the commit message what effect the patch will have. Then reviewers (including you) can read it and try it out to make sure what you say is true. The test suite is not very good for checking that a patch does what it’s meant to do, but that’s okay, since it has a different purpose [1]. As an example of what I mean, here is your patch 1/4 again (untested, though). I didn’t add any tests since it would be kind of hard to provoke address space exhaustion at just the right moment. [1] See http://thread.gmane.org/gmane.comp.version-control.git/142480/focus=142745 -- %< -- From: Benjamin C Meyer <bmeyer@xxxxxxx> Subject: scripts: use rev-parse --verify -q rather than using 2>/dev/null b1b3596 (2008-04-26) taught rev-parse --verify a --quiet option to suppress the “fatal: Needed a single revision” message when its argument is not a valid object. Use it; this simplifies scripts somewhat, and it allows other errors (such as address space exhaustion) to be reported properly. Since --quiet does not suppress warnings about ambiguous ref names and inadequate reflogs, the redirection has been kept for call sites that might involve either of these phenomena. Signed-off-by: Benjamin C Meyer <bmeyer@xxxxxxx> Signed-off-by: Jonathan Nieder <jrnieder@xxxxxxxxx> --- t3903-stash.sh fails for me with your original patch. Maybe you forgot to run 'make' before running tests?
