> I did some code analysis, and as a byproduct was able to identify some dead
> code in the form of files that can be safely removed. After filtering out
> some false positives, this is what remained:
> gms/IFailureNotification.java
> - was there since FB open-sourced Cassandra; has never been used for
> anything. No classes implement the interface, and it's not mentioned
> anywhere in the codebase.
> service/PendingRangeCalculatorServiceMBean.java
> - empty MBean used as a base class for PendingRangeCalculatorService, but has
> not been touched since being introduced several months ago. NOTE: removing
> this will require editing PendingRangeCalculatorService to not derive from
> this anymore.
> db/ColumnFamilyNotDefinedException.java
> - used to be thrown in original FB Cassandra; no longer used anywhere.
> db/context/IContext.java
> - introduced in 2c4ac98c9ffa8ea52da801830c7cdb745ddc28f0 (CASSANDRA-1072);
> was used extensively then, but no longer used anywhere.
> db/columniterator/SimpleAbstractColumnIterator.java
> - introduced in 48093358fb9022947592813a6aae43db148847ca (CASSANDRA-287); was
> used then; no longer used anywhere.
> thrift/RequestType.java
> - enum introduced in 72199e23ec9d604449bef87733a32e1da9924437
> (CASSANDRA-3272); was used then; no longer used anywhere.
> utils/AtomicLongArrayUpdater.java
> - introduced in 22e18f5a348a911f89deed9f9984950de451d28a (CASSANDRA-3578),
> but has never been used for anything. Not sure what the original intent
> might have been.
> utils/DefaultDouble.java
> - introduced in 96588d4f322dfbb1f5ff9328afe4377babfb1d2c (CASSANDRA-1715);
> was used then; no longer used anywhere.
> utils/LatencyTracker.java
> - introduced in 979a022f896aaa5a799b27a973cd476e5727820e (CASSANDRA-702); was
> used then; no longer used anywhere.
> utils/SkipNullRepresenter.java
> - introduced in a6777492280ae481392cd4cb4ba613923f84989d(CASSANDRA-1133) was
> used then; no longer used anywhere.
