From 3c92ea399d717dc45b3fa91424c0dadc0239ebf2 Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Sat, 2 Aug 2008 12:54:35 +0000 Subject: * Make nix-env --dry-run print the paths to be substituted correctly again. (After the previous substituter mechanism refactoring I didn't update the code that obtains the references of substitutable paths.) This required some refactoring: the substituter programs are now kept running and receive/respond to info requests via stdin/stdout. --- src/libutil/util.hh | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'src/libutil/util.hh') diff --git a/src/libutil/util.hh b/src/libutil/util.hh index 5d28a8308c..6c67e450b5 100644 --- a/src/libutil/util.hh +++ b/src/libutil/util.hh @@ -245,6 +245,10 @@ void killUser(uid_t uid); string runProgram(Path program, bool searchPath = false, const Strings & args = Strings()); +/* Close all file descriptors except stdin, stdout, stderr, and those + listed in the given set.
