mcilwain	30bfcf9c55	Remove more unused Truth8.assertThat() static imports in tests ... ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=173562809	2017-11-07 17:22:56 -05:00
mcilwain	c0f8da0c6e	Switch from Guava Optionals to Java 8 Optionals ... This was a surprisingly involved change. Some of the difficulties included java.util.Optional purposely not being Serializable (so I had to move a few Optionals in mapreduce classes to @Nullable) and having to add the Truth Java8 extension library for assertion support. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=171863777	2017-10-24 16:53:47 -04:00
nickfelt	499f1e7dbc	Rewrite ServerSecret caching and accessor logic ... I'm working on some changes to XsrfTokenManager (b/35388772) and ServerSecret was crufty enough that I ended up rewriting it. Now it uses a LoadingCache with a transaction instead of needlessly race-condition-y static init logic. It also now supports retrieving its value as either a UUID (the old format used by XsrfTokenManager) or a byte[]. The latter is more flexible and can be directly used with HMAC which the new XsrfTokenManager format will employ. And lastly, I added tests. In addition, I tested this code on alpha and verified appropriate operation (XSRF tokens still work from the console and from regtool; if you remove ServerSecret from datastore and memcache, it persists a new one). ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=148931620	2017-03-07 13:30:18 -05:00
