From 9de6bc5d05027363f968c20e53e8c3d5aa34f8b4 Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Tue, 20 Nov 2012 00:27:25 +0100 Subject: nix-store -r: Add ‘--ignore-unknown’ flag MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This flag causes paths that do not have a known substitute to be quietly ignored. This is mostly useful for Charon, allowing it to speed up deployment by letting a machine use substitutes for all substitutable paths, instead of uploading them. The latter is frequently faster, e.g. if the target machine has a fast Internet connection while the source machine is on a slow ADSL line. --- src/libmain/shared.cc | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'src/libmain/shared.cc') diff --git a/src/libmain/shared.cc b/src/libmain/shared.cc index 9e5964acf8bb..2cf5b08df32d 100644 --- a/src/libmain/shared.cc +++ b/src/libmain/shared.cc @@ -47,7 +47,14 @@ void printMissing(StoreAPI & store, const PathSet & paths) unsigned long long downloadSize, narSize; PathSet willBuild, willSubstitute, unknown; queryMissing(store, paths, willBuild, willSubstitute, unknown, downloadSize, narSize); + printMissing(willBuild, willSubstitute, unknown, downloadSize, narSize); +} + +void printMissing(const PathSet & willBuild, + const PathSet & willSubstitute, const PathSet & unknown, + unsigned long long downloadSize, unsigned long long narSize) +{ if (!willBuild.empty()) { printMsg(lvlInfo, format("these derivations will be built:")); foreach (PathSet::iterator, i, willBuild) -- cgit 1.4.1
