This may fix #910. PiperOrigin-RevId: 361551300 -- aed9ae1dffa7b228dcb6ffbeb2fe06a13970c72b by Laramie Leavitt <lar@google.com>: Propagate nice/strict/naggy state on absl::MockingBitGen. 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. PiperOrigin-RevId: 361233484 -- 96186023fabd13d01d32d60d9c7ac4ead1aeb989 by Abseil Team <absl-team@google.com>: Ensure that trivial types are passed by value rather than reference PiperOrigin-RevId: 361217450 -- e1135944835d27f77e8119b8166d8fb6aa25f906 by Evan Brown <ezb@google.com>: Internal change. PiperOrigin-RevId: 361215882 -- 583fe6c94c1c2ef757ef6e78292a15fbe4030e35 by Evan Brown <ezb@google.com>: Increase the minimum number of slots per node from 3 to 4. 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.

This benchmark has significantly different possible behaviors that can result in misleading metrics. 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. PiperOrigin-RevId: 360930639 -- 51f6bb97b9cbdb809c31b77e93ce080ca3cba9ea by Benjamin Barenblat <bbaren@google.com>: Stop testing with double-double random variables On POWER, long double is often represented as a pair of doubles added together (double-double arithmetic). We’ve already special-cased double-double arithmetic in a number of tests, but compiler bugs [1, 2, 3] have now triggered both false positives and false negatives, which suggests testing with double doubles is unlikely to yield useful signal. Remove the special casing and detect if we’re on a double-double system; if so, just don’t test long doubles.

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.

Use a virtual base class with template-specialized derived classes to implement match method rather than taking the address of a function specialization and using casts everywhere. This combines several of the previously type-erased pointers into a single object, eliminates the separate cleanup container previously used, and eliminates some gratuitous static_cast<>s.

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.

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.

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.

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

PiperOrigin-RevId: 291982551 -- 47ff4820e595f96c082a90d733725f6882d83e3b by Abseil Team <absl-team@google.com>: Improve ABSL_ATTRIBUTE_PACKED documentation Recommend to apply ABSL_ATTRIBUTE_PACKED to structure members instead of to an entire structure because applying this attribute to an entire structure may cause the compiler to generate suboptimal code. It reduces the alignment of the data structure from a value larger than one to one. When applied to a structure, ABSL_ATTRIBUTE_PACKED reduces the alignment of a structure (alignof()) to 1. As a result, the compiler can no longer assume that e.g. uint32 members are aligned on a four byte boundary and hence is forced to use single-byte load and store instructions on CPU architectures that do not support non-aligned loads or stores.

In some configurations, initializing NominalCPUFrequency() requires spending at least 3ms measuring the CPU frequency. By separating the initialization from NumCPUs(), which is called in most configurations, we can save at least 3ms of program startup time.

This is currently experimental and unsupported. This CL does a few things: 1. Adds the ABSL_DLL macro to any class holding a static data member, or to global constants in headers. 2. Adds a whitelist of all files in the DLL and all the build targets that are conglomerated into the DLL. 3.

Because MockingBitGen can return random values, it is inherently flaky. For log-unifrom, 2040 is a common enough value that tests failed unreasonably frequently. Replacing it with a significantly larger value so as to be much less common. 50000 is a good choice because it is (tied for) the least likely to occur randomly from this distribution, but is still in the distribution.

In GCC9, `CompressedTuple<std::any>` and `std::tuple<std::any>` both fail for the same reasons, and a proper "fix" requires updating `std::any`, which is out of our control.

Instead callback guard and callback function are combined into a single CallbackData struct, while primary data lock is stored separately. * CallbackData member of class FlagImpl is initially set to be nullptr and is only allocated and initialized when a flag's callback is being set. For most flags we do not pay for the extra space and extra absl::Mutex now. * Primary data guard is stored in data_guard_ data member. This is a properly aligned character buffer of necessary size. During initialization of the flag we construct absl::Mutex in this space using placement new call. * We now avoid extra value copy after successful attempt to parse value out of string. Instead we swap flag's current value with tentative value we just produced.

PiperOrigin-RevId: 279966541 -- 4336f8b10cff906e2defdd7d1d449cde4907da5d by Abseil Team <absl-team@google.com>: Add comments and relax memory orders in base_internal::CallOnceImpl. Add a comment to document the memory order guarantee if base_internal::SpinLockWait() is called and returns kOnceDone. Add a comment for the load/store sequence in base_internal::CallOnceImpl based on Mike Burrows' explanation. The atomic load of 'control' in the #ifndef NDEBUG block does not need std::memory_order_acquire. It can use std::memory_order_relaxed. The atomic compare_exchange_strong of 'control' does not need std::memory_order_acquire in the success case. It can use std::memory_order_relaxed.

PiperOrigin-RevId: 277376952 -- 874eeaa3b3af808fc88b6355245f643674f5e36e by Abseil Team <absl-team@google.com>: Don't use atomic ops on waiter and wakeup counts in CONDVAR waiter mode. Just guard the waiter and wakeup counts with the mutex. This eliminates the race. Also fix a typo in the error message for pthread_cond_timedwait. PiperOrigin-RevId: 277366017 -- ce8c9a63109214519b5a7eaecef2c663c4d566df by Greg Falcon <gfalcon@google.com>: Implement the config options for our four main C++ forward compatibility types. These options control whether the names `any`, `optional`, `string_view`, and `variant` in namespace `absl` are aliases to the corresponding C++17 types in namespace `std`. By default, we continue to auto-detect the configuration of the compiler being run. These options are not intended to be modified on the command line (as -D flags, say). Instead, the options.h file can be modified by distributors of Abseil (e.g., binary packagers, maintainers of local copies of Abseil, etc.) Changing options will change Abseil in an ODR sense. Any program must only link in a single version of Abseil. Linking libraries that use Abseil configured with different options is an error: there is no ABI compatibility guarantee when linking different configurations, even if the Abseil versions used are otherwise exactly identical.

By default CMake's `add_library` creates the target as a static library. However, users can override the default using the builtin CMake option -DBUILD_SHARED_LIBS=ON. This changes Abseil's CMake to respect this configuration option by removing the explicit `STATIC` in our usages of `add_library`.

ABSL_TEST_COPTS should be preferred for all tests so that they are configured consistently (moreover, CMake should agree with Bazel).

In absl::FromTM, the tm.tm_year is added by 1900 regarding that tm.tm_year represents the years since 1900. This change checks integer overflow before doing the arithmetic operation.

Fixes #386 PiperOrigin-RevId: 272979749 -- c53103e71b2a6063af3c6d4ff68aa2d8f9ae9e06 by Abseil Team <absl-team@google.com>: Try to become idle only when there is no wakeup. Immediately after waking up (when futex wait returns), the current thread tries to become idle doing bunch of memory loads and a branch. Problem is that there is a good chance that we woke up due to a wakeup, especially for actively used threads. For such wakeups, calling MaybeBecomeIdle() would be a waste of cycles. Instead, call MaybeBecomeIdle() only when we are sure there is no wakeup. For idle threads the net effect should be the same. For active, threads this will be more efficient. Moreover, since MaybeBecomeIdle() is called before waiting on the futex, the current thread will try to become idle before sleeping. This should result in more accurate idleness and more efficient release of thread resources.

On this platform, constexpr static init sometimes happens after dynamic init =/. When it does, we should not zero hook_ (overwriting the value written there by dynamic init); instead we should leave it alone. This works even when constexpr static init goes first since all uses of AtomicHook should have static storage duration and be zero-initialized. https://developercommunity.visualstudio.com/content/problem/336946/class-with-constexpr-constructor-not-using-static.html PiperOrigin-RevId: 272525226 -- d01b14fc06bc75b41c51976ed32e7c304ea1aab7 by Abseil Team <absl-team@google.com>: exclude emscripten from running tests involving long doubles PiperOrigin-RevId: 272497628 GitOrigin-RevId: 3e60f355db5afd7a864591d81a6c383b6c0a0780 Change-Id: I3c8a8f5acaf7652a06ef40cf028ef5d2e142f81b
