How long is "too long"? I'm trying to find the root cause of my app's TMCache crash issues, but I'm not finding this to be a problem. I ran a test on TMCache to this effect in which I take the key passed into TMCache and make it 18x longer via
NSString *key = [NSString stringWithFormat:@"%@%@%@%@%@%@%@%@%@%@%@%@%@%@%@%@%@%@", baseKey, baseKey, baseKey, baseKey, baseKey, baseKey, baseKey, baseKey, baseKey, baseKey, baseKey, baseKey, baseKey, baseKey, baseKey, baseKey, baseKey, baseKey];
Then I logged out the byte size of each key being used. I got the following results, with no failures nor crashing:
fetching a 1800 byte long key
fetching a 1818 byte long key
fetching a 1800 byte long key
setting a 1908 byte long key
setting a 1710 byte long key
setting a 1890 byte long key
fetching a 1440 byte long key
fetching a 1440 byte long key
setting a 1818 byte long key
setting a 4986 byte long key
setting a 1440 byte long key
setting a 1674 byte long key
setting a 1818 byte long key
setting a 1800 byte long key
fetching a 1908 byte long key
fetching a 1710 byte long key
You can see these are exceptionally long keys, with one that is about 5K, let alone the file path it uses for storage. TMCache didn't flinch on any of these. Testing was done on-device (iPhone 6+, iOS 8.1.2)
