It is never interputed (EINTR) and uses the same source as /dev/urandom. https://man7.org/linux/man-pages/man3/getentropy.3.html getrandom has been in the Linux since kernel 3.17 When unavailable (ENOSYS), fallback to /dev/urandom.

We don't use the extra byte - we only need the first `capacity` ones that are valid, the one sentinel byte and then `Group::kWidth - 1` cloned control bytes. For example, in `EmptyGroup()`, where capacity is 0, we use `Group::kWidth` control bytes. We need to update set_ctrl() to only mirror `Group::kWidth - 1` bytes instead of `Group::kWidth` bytes. Note: this doesn't actually save memory unless `alignof(value_type)` is one. Also add/update related comments.

Before this change, we had two classes named HashState: absl::HashState, the public API used for type erasure, and absl::hash_internal::HashState, the internal concrete implementation ordinarily used. The internal class used to be named `CityHashState`, but we renamed it to `HashState` it when we changed underlying hash implementation to wyhash. This inadvertent naming conflict made the code much harder to read, and this change intends to undo that. PiperOrigin-RevId: 373481959 -- 4aec55ffddebd085c239352a2e20721091f719a1 by Greg Falcon <gfalcon@google.com>: Introduce absl::HashOf(), a convenience wrapper around absl::Hash that calculates hashes from the values of its arguments. PiperOrigin-RevId: 373461406 -- 86b5fd8db50bbc8bd0aa9258523527381fe0445d by Abseil Team <absl-team@google.com>: Improve speed of BlockingCounter by making its most common path lock free. With the new implementation, the fast path of BlockingCounter::DecrementCount() is only a fetch_sub operation. This is most times much more efficient than the previous implementation (full mutex lock/unlock). As a matter of fact, in most actual usecases in practice, the waiter thread is already waiting on the Wait() call when DecrementCount() is called, which makes Mutex::Unlock() take the slow path as there's a waiter thread that it might need to wake up. PiperOrigin-RevId: 373394164 -- 65c876be5eac0cd32583ff8535ede4109d39cf3f by Martijn Vels <mvels@google.com>: Move the 'sample copied cord' logic into MaybeTrackCord(), This changes move the logic for selecting if a cord should remain being sampled from Cord to CordzInfo::MaybeTrackCord, and updates the documentation for the latter method.

This creates uniformly distributed buckets, each with a probability of sending traffic to a different bucket. Abseil represents a bucket as a pair (probability of retaining traffic × alternate bucket if traffic is passed) and a distribution as a vector of such pairs. For example, {(0.3, 1), (1.0, 1)} represents a distribution with two buckets, the zeroth of which passes 70% of its traffic to bucket 1 and the first of which holds on to all its traffic. This representation is not unique: When a bucket retains traffic with probability 1, the alternate bucket is irrelevant. Continuing the example above, {(0.3, 1), (1.0, 0)} _also_ represents a two-bucket distribution where the zeroth bucket passes 70% of its traffic to the first and the first hangs on to all traffic. Exactly what representation Abseil generates for a given input is related to how much precision is used in intermediate floating-point operations, which is an architectural implementation detail. Remove sensitivity to that detail by not examining the alternate bucket when the retention probability is 1.0.

Cord is responsible for synchronizing updates for sampled cords such that the CordRep* contained in CordzInfo is at all times valid. This is done by scoping Lock() and Unlock() calls around the code modifying the code of a sampled cord. For example (using the future CL CordzUpdateScope()): CordzInfo* cordz_info = get_cordz_info(); CordzUpdateScope scope(cordz_info, CordzUpdateTracker::kRemovePrefix); CordRep* rep = RemovePrefixImpl(root); set_tree(rep); if (cordz_info) { cordz_info->SetCordRep(rep); } On CordzInfo::Unlock(), if the internal rep is null, the cord is no longer sampled, and CordzInfo will be deleted. Thus any update resulting in the Cord being inlined will automatically no longer be sampled.

This change adds a `rep` property to CordzInfo, which is intended to be used by collection logic. Mini design: Cord invokes TrackCord() providing the active 'root' cordrep of the newly sampled Cord, returning a CordzInfo with a weak (uncounted) reference to this root. Cord invokes `SetCordRep()` each time the root cordrep of the sampled Cord is updated while holding `mutex()`. Cord must also obtain `mutex()` _before_ removing a reference on the old root. i.e.: Cord must guarantee that the (weak) reference held in CordzInfo is at all times valid. CordzInfo collection code can then safely obtain a (reference counted) rep pointer by adding a reference to `rep_` while holding `mutex()`. This requires only a very brief critical section inside CordzInfo logic, minimizing contention with concurrent Cord updates. Cord code should typically obtain and hold `mutex()` for the entirety of each mutating Cord operation on a sampled cord. As Cord is thread compatible, it never competes on the lock with any other thread. The only possible concurrent access is from Cordz collection code, which should be a relatively rare event.

Further, bring the implementation on par with libiberty's demangler grammar. Clang introduced option -funique-internal-linkage-names that adds the suffix ".__uniq.[0-9]+" to internal linkage functions to give them a globally unique identifier. The suffix was designed to work with existing demanglers which do recognize a "_" along with the alphanumeric string. This change enhances the demangler to allow "_" with the alphanumeric string. Please refer to libiberty's cp-demangle.c where function d_clone_suffix implements the demangling of clone suffixes : 1. '_' is accepted as a valid character with the alphanumeric sequence. 2. The alphanumberic sequence is optional. 3. The digit sequence is optional.

Allowing NiceMocks reduces the log spam for un-mocked calls, and it enables nicer setup with ON_CALL, so it is desirable to support it in absl::MockingBitGen. Internally, gmock tracks object "strictness" levels using an internal API; in order to achieve the same results we detect when the MockingBitGen is wrapped in a Nice/Naggy/Strict and wrap the internal implementation MockFunction in the same type. This is achieved by providing overloads to the Call() function, and passing the mock object type down into it's own RegisterMock call, where a compile-time check verifies the state and creates the appropriate mock function.

We also rename kNodeValues (and related names) to kNodeSlots to make it clear that they are about the number of slots per node rather than the number of values per node - kMinNodeValues keeps the same name because it's actually about the number of values rather than the number of slots. Motivation: I think the expected number of values per node, assuming random insertion order, is the average of the maximum and minimum numbers of values per node (kNodeSlots and kMinNodeValues). For large and/or even kNodeSlots, this is ~75% of kNodeSlots, but for kNodeSlots=3, this is ~67% of kNodeSlots. kMinNodeValues (which corresponds to worst-case occupancy) is ~33% of kNodeSlots, when kNodeSlots=3, compared to 50% for even kNodeSlots. This results in higher memory overhead per value, and since this case (kNodeSlots=3) is used when values are large, it seems worth fixing.

Specifically, we can have a case where we are deallocating the last node in the b-tree in the erase and then allocating a new node in the insert call repeatedly, whereas normally, we end up just inserting/erasing a value from the last node. Also, the name of the benchmark is misleading because it involves an erase and an insert, but the name only mentions the insert.

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.
