From 2cf14db857fa4be3b60b6497bc4458d5b589154f Mon Sep 17 00:00:00 2001 From: Niels Egberts Date: Sun, 11 Jul 2021 11:15:06 +0100 Subject: Throw on unexpected input for --delete-older-than '--delete-older-than 10' deletes the generations older than a single day, and '--delete-older-than 12m' deletes all generations older than 12 days. This changes makes it throw on those invalid inputs, and gives an example of a valid input. --- src/libstore/profiles.cc | 3 +++ 1 file changed, 3 insertions(+) (limited to 'src/libstore/profiles.cc') diff --git a/src/libstore/profiles.cc b/src/libstore/profiles.cc index 5d1723886..75db8f9df 100644 --- a/src/libstore/profiles.cc +++ b/src/libstore/profiles.cc @@ -211,6 +211,9 @@ void deleteGenerationsOlderThan(const Path & profile, time_t t, bool dryRun) void deleteGenerationsOlderThan(const Path & profile, const string & timeSpec, bool dryRun) { + if (timeSpec.empty() || timeSpec[timeSpec.size() - 1] != 'd') + throw Error("invalid number of days specifier '%1%', expected something like '14d'", timeSpec); + time_t curTime = time(0); string strDays = string(timeSpec, 0, timeSpec.size() - 1); auto days = string2Int(strDays); -- cgit v1.2.3
