To minimize impact on migration and existing tests using empirical assumptions on growth, this change makes the btree use the same rate as Concat logic.

PiperOrigin-RevId: 387585161 -- 206d298e2bccb998731995cb05717b31fa9d90ec by Abseil Team <absl-team@google.com>: Internal change PiperOrigin-RevId: 387577465 -- f07fafe8a400a4f5dfef186d1a3b61fb7f709fe5 by Abseil Team <absl-team@google.com>: This change adds debug-build enforcement that the inputs to absl::c_set_intersection are sorted, which is a prerequisite of std::set_intersection and required for correct operation of the algorithm. PiperOrigin-RevId: 387446657 -- 2ca15c6361bb758be7fb88cae82bf8489b4d3364 by Abseil Team <absl-team@google.com>: Change BadStatusOrAccess::what() to contain status_.ToString() This ensures that on uncaught exception propagation that would cause program termination, the message contains information on the error which caused the failure. Lazy initialization of what_ is a value judgement: if most callers are expected to call status() not what(), lazy initialization is correct. If most callers are expected to call what(), it should be initialized on construction to avoid atomic operation overhead.

This makes it consistent with the rest of the API (Next, Previous, Skip) and hardens it against invariants that are harder (or less likey) to be upheld correctly by the caller.

PiperOrigin-RevId: 381276748 -- da32624792d2948fe83d0ce58794d505799ab5d0 by Benjamin Barenblat <bbaren@google.com>: s/round/rint/ in exponential_biased `rint` differs from `round` in that it uses the current FPU rounding mode. It’s thus potentially faster, since it doesn’t have to save and restore FPU state. It also is more reflective of developer intent – most developers expect all FPU operations to use the current rounding mode, and having exponential_biased follow that rule seems ideal.

I found myself implementing a similar option in our tensorstore project to fuzz test a storage layer and figured that it would be more useful as a common tool with defaults that take the non-random path. This is similar to the FuzzedDataProvider mechanism which generates random values from a fuzz string, and is used to generate fuzz test inputs, and internally it uses FuzzedDataProvider. The basic technique used here is to construct mocking lambdas for all of the absl mock distribution configurations, and forwarding the parameters to fuzzing-specific implementations that call into FuzzedDataProvider.

In particular, we optimize for empty vectors in both cases. Added a couple of benchmarks that copy either an InlVec<int64> or an InlVec<InlVec<int64>>. Speed difference: ``` BM_CopyTrivial/0 0.92ns +- 0% 0.47ns +- 0% -48.91% (p=0.000 n=11+12) BM_CopyTrivial/1 0.92ns +- 0% 1.15ns +- 0% +25.00% (p=0.000 n=10+9) BM_CopyTrivial/8 8.57ns +- 0% 10.72ns +- 1% +25.16% (p=0.000 n=10+12) BM_CopyNonTrivial/0 3.21ns +- 0% 0.70ns +- 0% -78.23% (p=0.000 n=12+10) BM_CopyNonTrivial/1 5.88ns +- 1% 5.51ns +- 0% -6.28% (p=0.000 n=10+8) BM_CopyNonTrivial/8 21.5ns +- 1% 15.2ns +- 2% -29.23% (p=0.000 n=12+12) ``` Note: the slowdowns are a few cycles which is expected given the procedure call added in that case. We decided this is a good tradeoff given the code size reductions and the more significant speedups for empty vectors. Size difference (as measured by nm): ``` BM_CopyTrivial from 1048 bytes to 326 bytes. BM_CopyNonTrivial from 749 bytes to 470 bytes. ``` Code size for a large binary drops by ~500KB (from 349415719 to 348906015 348906191).

The old pattern of access breaks the `CordRep` type abstraction; since `CordRep::data` is not in general guaranteed to contain the chunk's data, we shouldn't access it that way. This incidentally adds an assertion check (via the flat() accessor) that the CordRep is indeed flat on each such access, but a manual inspection of the code, as well as the fact that this code currently works, suggest that this is always true.)

Keeping the global state as separate global variables results in two issues: 1) False sharing with adjacent global data (e.g., cycle clock source), since the global fields are updated every O(10usec). 2) The hot global fields (e.g., seq and samples) can reside on different cache lines. To fix this, simply wrap the global data in a ABSL_CACHE_ALIGNED structure. This is similar to what we do for MutexGlobals.

The main purpose is to make upcoming ring buffer changes easier to isolate from existing cord.cc code. Notice that this removes the nullptr check from Unref() and now requires it to be non null (which held true most times). We may need to rethink if the 'unref unlikely one' is the common case: are cordreps most likely shared? This may be something between 'root' and non root nodes, i.e., is it more likely for leaf / flat nodes in large cords to be shared than top level cordreps being shared? Vice versa? Benchmarks say that we mostly shouldn't care, the caveat being that atomic ops seem more expensive on upcoming archs (arcadia) so we should error on the side of an extra IsOne() branch saving us single owned atomic ops.

PiperOrigin-RevId: 320384329 -- c7b1dacda2739c10dc1ccbfb56b07ed7fe2464a4 by Laramie Leavitt <lar@google.com>: Improve FastUniformBits performance for std::minstd_rand. The rejection algorithm was too pessimistic before, and not in line with the [rand.adapt.ibits]. Specifically, when sampling from an URBG with a non power of 2 range, FastUniformBits constructed a rejection threshold with a power-of-2 range that was too restrictive. For example, minstd_rand has a range of [1, 2147483646], which has a range of 2145386495, or about 30.999 bits. Before FastUniformBits rejected values between 1<<30 and 2145386495, which includes approximately 50% of the generated values. However, since a minimum of 3 calls are required to generate a full 64-bit value from an entropy pool of 30.9 bits, the correct value for rejection sampling is the range value which masks 21 (0x7fe00000) or 22 bits and rejects values greater than that. This reduces the probability of rejecting a sample to about 0.1% NOTE: Abseil random does not guarantee sequence stability over time, and this is expected to change sequences in some cases.

Starting in C++17, when invoke'ing a pointer-to-member, if the object representing the class is a reference_wrapper, that wrapper is unpacked. Because we implement a number of functional APIs that closely match C++ standard proposals, it is better if we follow the standard's notion of what "invoking" means. This also makes `absl::base_internal::Invoke()` match `std::invoke()` in C++17. I intend to make this an alias in a follow-up CL.

In Abseil random, mocking was split across two different classes, MockingBitGenBase and MockingBitGen. This split existed because Google Mock is a test-only library that we don't link into production, so MockingBitGenBase provided a low-overhead scaffold used to lookup mocks when in test code, but which is unused in production code. That has been replaced by type-erasure which looks for a method named CallImpl with the correct signature. Weaken the coupling between MockingBitGen, DistributionCaller, and MockOverloadSet. Rename CallImpl to InvokeMock() Previously, the implementation of DistributionCaller was also split across different files using explicit instantiation of the DistributionCaller struct and some details in the Mocking classes. Now Distribution caller uses the presence of the InvokeMock() method to choose whether to use the mockable call path or the default call path.

PiperOrigin-RevId: 312707974 -- 34484d18dfb63a0a7ad6e2aaeb570e33592968be by Abseil Team <absl-team@google.com>: Let Cord::Cord(string&&), Cord::operator=(string&&), Cord::Append(string&&), and Cord::Prepend(string&&) steal string data and embed it into the Cord as a single external chunk, instead of copying it into flat chunks (at most 4083-byte each). Stealing string data is faster, but it creates a long chunk, which leads to a higher more memory usage if its subcords are created and outlive the whole Cord. These functions revert to copying the data if any of the following conditions holds: - string size is at most kMaxBytesToCopy (511), to avoid the overhead of an external chunk for short strings; - less than half of string capacity is used, to avoid pinning to much unused memory.

This change allows us to do the following: * We can move most of "vtable" implementation from handle header, which will become public soon, into implementation details of Abseil Flag. * We can combine back marshalling ops and general ops into a single vtable routine. They were split previously to facilitate type identification without requiring marshalling routines to be exposed in header. * We do not need to store two vtable pointers. We can now store only one. The static type id can be deduced on request. Overall we are saving 24 bytes per flag according to size_tester run.
