-- 1a5831c2b4b85e0151b7952e47f4b80827937620 by Laramie Leavitt <lar@google.com>: Implement FuzzingBitGen, an adapter which allows existing randomized tests which use absl::BitGenRef to easily integrate with fuzz testing. 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. The default paths for the distributions are either the bounds or a median value.

-- b927776da818c674a674e46a7bbbdd54170a0ad3 by Todd Lipcon <tlipcon@google.com>: Include priority in the calculation of mutex waiter equivalence This changes the behavior of the absl::Mutex wait list to take into account waiter priority when creating "skip chains". A skip chain on the wait list is a set of adjacent waiters that share some property and enable skipping during traversal. Prior to this CL, the skip chains were formed of waiters with the same wait type (e.g. exclusive vs read) and Condition. With this CL, the priority is also taken into account. This avoids O(n) behavior when enqueueing a waiter onto a wait list where the oldest waiter is at a lower priority than the waiter to be enqueued. With the prior notion of equivalence class, a skip chain could contain waiters of different priority, so we had to walk the linked list one-by-one until finding the appropriate insertion point. With the new equivalence class computation, we can skip past all of the equivalent waiters to find the right insertion point. This gives a substantial improvement to the enqueue performance in the case where there's already a waiter at lower priority. Note that even though this code path isn't a hot one, it's performed while holding the Mutex's spinlock, which prevents other threads from unlocking the Mutex, so minimizing the time under the critical section can have "knock-on" throughput benefits.

-- f0456157cdc6cef6dbb5d2f99f9dc3ca0e213fab by Abseil Team <absl-team@google.com>: Improve flag_benchmark reproducibility, test multiple threads This adds multiple threads to the flags benchmark, and also uses some linker magic to ensure that the defined flags are mapped to a consistent alignment regardless of other code changes in the benchmark binary. The benchmark performance in multiple threads is somewhat sensitive to the alignment of the FlagImpl class, depending on whether the flag value and the absl::Mutex are on the same cacheline or different ones. Making all flags be cacheline-aligned would probably waste too much memory, so this CL instead just makes the memory alignment consistent within the tests.

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: 342889378 -- bb77e07abff4dbd0a9c97eb85ee85cb39b84d04a by Abseil Team <absl-team@google.com>: Extract `find_first_not_full` outside of the raw_hash_set. This function is used in the following scenarios: 0. [relatively hot] insert, when actual new element is added. 1. [relatively cold] resize (explicit or on capacity grow) 2. [relatively cold] copy constructor 3. [cold] rehash on insert/erase (aka cache) use cases Resize typically mitigated by `reserve` in performance critical cases. Rehashing happen relatively rare, when hash table become polluted with deleted slots. We keep `find_first_not_full` in header, so that compiler still can inline it, when necessary (most notably in insert use case). This reduce binary size since only one copy of this function will be present in the binary for all tables where the function is not inlined (at least in one case).

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: 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.

PiperOrigin-RevId: 314600027 -- 6c452aa1ee7e46ab941ba7d1fa636da8ea3d7370 by Laramie Leavitt <lar@google.com>: Remove the MockingBitGenBase base class in favor of type-erasure in BitGenRef. 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.

It's reasonable to test that the BitGen itself has good entropy, however when testing the cross product of all random distributions x all the architecture variations x all submitted changes results in a large number of tests. In order to account for these failures while still using good entropy requires that our allowed sigma need to account for all of these independent tests. Our current sigma values are too restrictive, and we see a lot of failures, so we have to either relax the sigma values or convert some of the statistical tests to use deterministic values. This changelist does the latter. PiperOrigin-RevId: 311840096 GitOrigin-RevId: f012012ef78234a6a4585321b67d7b7c92ebc266 Change-Id: Ic84886f38ff30d7d72c126e9b63c9a61eb729a1a |
