Our users complain about these. This does not catch issues in header-only libraries (like btree.h) but we may work on those in the future PiperOrigin-RevId: 338967089 -- 0c062c542a4c61ea0f65d25811827c0858e3adde by Abseil Team <absl-team@google.com>: Improve cache-locality for ThreadIdentity and PerThreadSynch. This is a change based on an observation in RPC benchmarks that shows significant cycles being spent in waking up a thread, 99.8% of which was on cache misses. Investigating this a bit more, it turns out to be due to sharing the cache line with the waiter state. To fix this issue, the following changes are introduced: - Reorder fields in PerThreadSync so that it fits in a single cache line The size of this structure was 80 bytes before this change. Note: Manually inspected all booleans to make sure they are not modified by multiple threads concurrently.

PiperOrigin-RevId: 338568224 -- da5e09a7fedb3217329465d9206b7cbc6677176b by Abseil Team <absl-team@google.com>: Add `absl_btree_prefer_linear_node_search` Allow keys of `btree_set`, `btree_map`, `btree_multiset`, and `btree_multimap` to opt-in to linear search (instead of binary search). Linear search was used previously for arithmetic types with `key_compare` of `std::greater` or `std::less`. For example, this would be useful for key types that wrap an integer and define their own cheap `operator<()`. ``` class K { public: using absl_btree_prefer_linear_node_search = std::true_type; ... private: friend bool operator<(K a, K b) { return a.k_ < b.k_; } int k_; }; absl::btree_map<K, V> m; // Uses linear search assert((absl::btree_map<K, V>::testonly_uses_linear_node_search())); ``` PiperOrigin-RevId: 338476553 -- c56ead7ce6b0a5ad32e3a42904c686448a69451e by Gennadiy Rozental <rogeeff@google.com>: Import of CCTZ from GitHub.

Also, document why we can't provide mutable access to the key without C++17. Note: we use Policy::mutable_key() because btree already uses Policy::key() internally to get const key access, and we want to avoid calling std::launder unless we need mutable access to the key.

PiperOrigin-RevId: 324431690 -- e5b579f3f1aa598c1f62e71dba7103b98811de59 by Laramie Leavitt <lar@google.com>: Bugfix: Fix bounds in absl::Uniform where one of the bounds is min/max. When absl::Uniform(rng, tag, a, b) is called, the tag is used in conjunction with the type to determine whether or not to manipulate the bounds to make them inclusive or exclusive through the uniform_*_bound functions. Unfortunately, at limits of the interval the function was not well behaved. The previous implementation used wrapping arithmetic. This causes incorrect bounds computation at the extremes (numeric_limits::min / numeric_limits::max) the bound would wrap. Improve this situation by: 1/ Changing the uniform_*_bound functions to use saturating arithmetic instead of wrapping, thus in the unsigned case, the upper_bound of IntervalOpenOpen for 0 is now 0, rather than numeric_limits::max, likewise for the lower bound. 2/ Adjusting the hi/lo checks in the distributions. When the interval is empty, such as for absl::Uniform(absl::IntervalOpenOpen, gen, 1, 0), the return value is somewhat nonsensical. Now absl::Uniform more consistently returns the low input rather than any adjusted input. In the above case, that means that 1 is returned rather than 2. NOTE: Calls to absl::Uniform where the resolved upper bound is < the lower bound are still ill-formed and should be avoided. 3/ Adding better tests. The underlying uniform_*_distribution classes are not affected.
