From b43e1e186e50bedc30d05d063dffbd751c1ff161 Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Wed, 15 May 2019 15:38:24 +0200 Subject: [PATCH] CachedDownloadResult: Include store path Also, make fetchGit and fetchMercurial update allowedPaths properly. (Maybe the evaluator, rather than the caller of the evaluator, should apply toRealPath(), but that's a bigger change.)
