From 4455e5d4b6f30d4ce042c68c8285b2062d146197 Mon Sep 17 00:00:00 2001 From: Felix Krause Date: Thu, 7 Jul 2016 18:13:12 +0200 Subject: `==` in tables should not raise KeyError * With previous code, the compiler deduced that equalsImpl may raise a KeyError. While this could only actually happen in a nasty multi-threaded environment, I fixed the code so that it will never happen. --- lib/pure/collections/tables.nim | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'lib/pure/collections') diff --git a/lib/pure/collections/tables.nim b/lib/pure/collections/tables.nim index e454a43cb..8d5fbdfc3 100644 --- a/lib/pure/collections/tables.nim +++ b/lib/pure/collections/tables.nim @@ -304,8 +304,9 @@ template equalsImpl() = # to use the slow route here: for key, val in s: # prefix notation leads to automatic dereference in case of PTable - if not t.hasKey(key): return false - if t[key] != val: return false + try: + if t[key] != val: return false + except KeyError: return false return true proc `==`*[A, B](s, t: Table[A, B]): bool = -- cgit 1.4.1-2-gfad0
