From f32fef1b075f63ecf8c7351c5e67d4dd95c0fb80 Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Wed, 17 Sep 2008 14:52:35 +0000 Subject: * GC option `--max-atime' that specifies an upper limit to the last accessed time of paths that may be deleted. Anything more recently used won't be deleted. The time is specified in time_t, e.g. seconds since 1970-01-01 00:00:00 UTC; use `date +%s' to convert to time_t from the command line. Example: to delete everything that hasn't been used in the last two months: $ nix-store --gc -v --max-atime $(date +%s -d "2 months ago") --- src/nix-store/nix-store.cc | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'src/nix-store') diff --git a/src/nix-store/nix-store.cc b/src/nix-store/nix-store.cc index dde04a4a8651..481e26cdbb17 100644 --- a/src/nix-store/nix-store.cc +++ b/src/nix-store/nix-store.cc @@ -531,8 +531,14 @@ static void opGC(Strings opFlags, Strings opArgs) else if (*i == "--max-freed") options.maxFreed = getIntArg(*i, i, opFlags.end()); else if (*i == "--max-links") options.maxLinks = getIntArg(*i, i, opFlags.end()); else if (*i == "--use-atime") options.useAtime = true; + else if (*i == "--max-atime") { + options.useAtime = true; + options.maxAtime = getIntArg(*i, i, opFlags.end()); + } else throw UsageError(format("bad sub-operation `%1%' in GC") % *i); + if (!opArgs.empty()) throw UsageError("no arguments expected"); + PrintFreed freed(options.action == GCOptions::gcDeleteDead, results); store->collectGarbage(options, results); @@ -745,7 +751,7 @@ void run(Strings args) indirectRoot = true; else if (arg[0] == '-') { opFlags.push_back(arg); - if (arg == "--max-freed" || arg == "--max-links") { /* !!! hack */ + if (arg == "--max-freed" || arg == "--max-links" || arg == "--max-atime") { /* !!! hack */ if (i != args.end()) opFlags.push_back(*i++); } } -- cgit 1.4.1
