From 77d272623fb4fd57cf27d4b92a7dc1713a2d4098 Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Sun, 22 Mar 2009 17:36:43 +0000 Subject: * NAR archives: handle files larger than 2^32 bytes. Previously it would just silently store only (fileSize % 2^32) bytes. * Use posix_fallocate if available when unpacking archives. * Provide a better error message when trying to unpack something that isn't a NAR archive. --- src/nix-store/nix-store.cc | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) (limited to 'src/nix-store/nix-store.cc') diff --git a/src/nix-store/nix-store.cc b/src/nix-store/nix-store.cc index f6271d56a..4a70d870a 100644 --- a/src/nix-store/nix-store.cc +++ b/src/nix-store/nix-store.cc @@ -617,16 +617,19 @@ static void opExport(Strings opFlags, Strings opArgs) static void opImport(Strings opFlags, Strings opArgs) { bool requireSignature = false; - for (Strings::iterator i = opFlags.begin(); - i != opFlags.end(); ++i) + foreach (Strings::iterator, i, opFlags) if (*i == "--require-signature") requireSignature = true; else throw UsageError(format("unknown flag `%1%'") % *i); if (!opArgs.empty()) throw UsageError("no arguments expected"); FdSource source(STDIN_FILENO); - while (readInt(source) == 1) + while (true) { + int n = readInt(source); + if (n == 0) break; + if (n != 1) throw Error("input doesn't look like something created by `nix-store --export'"); cout << format("%1%\n") % store->importPath(requireSignature, source) << std::flush; + } } -- cgit v1.2.3
