-- 93c607726d663800b4bfa472cba043fd3f5d0e97 by Derek Mauro <[email protected]>: Internal change PiperOrigin-RevId: 389158822 -- 55b3bb50bbc168567c6ba25d07df2c2c39e864af by Martijn Vels <[email protected]>: Change CordRepRing alternative implementation to CordRepBtree alternative. This changes makes CordRepBtree (BTREE) the alternative to CordRepConcat (CONCAT) trees, enabled through the internal / experimental 'cord_btree_enabled' latch. PiperOrigin-RevId: 389030571 -- d6fc346143606c096bca8eb5029e4c429ac6e305 by Todd Lipcon <[email protected]>: Fix a small typo in SequenceLock doc comment PiperOrigin-RevId: 388972936 -- e46f9245dce8b4150e3ca2664e0cf42b75f90a83 by Martijn Vels <[email protected]>: Add 'shallow' validation mode to CordRepBtree which will be the default for internal assertions. PiperOrigin-RevId: 388753606 -- b5e74f163b490beb006f848ace67bb650433fe13 by Martijn Vels <[email protected]>: Add btree statistics to CordzInfo, and reduce rounding errors PiperOrigin-RevId: 388715878 -- 105bcbf80de649937e693b29b18220f9e6841a51 by Evan Brown <[email protected]>: Skip length checking when constructing absl::string_view from `const char*`. The length check causes unnecessary code bloat.
