PiperOrigin-RevId: 362040582 -- ac704b53a49becc42f77e4529d3952f8e7d18ce4 by Abseil Team <absl-team@google.com>: Fix a typo in a comment. PiperOrigin-RevId: 361576641 -- d20ccb27b7e9b53481e9192c1aae5202c06bfcb1 by Derek Mauro <dmauro@google.com>: Remove the inline keyword from functions that aren't defined in the header. 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.

PiperOrigin-RevId: 348836291 -- 9a438cdcf2bd8d2b7ab27f4955432abf0d087672 by Evan Brown <ezb@google.com>: Fix a bug affecting b-tree extract() when there are multiple keys in the container that are equivalent to the lookup key. In that case, we are supposed to extract the first such key in the container - [reference](https://en.cppreference.com/w/cpp/container/multiset/extract), but we were extracting the first one we found (which was not necessarily the first in the container). Also, optimize internal_lower_bound to not keep searching all the way to the leaf if it finds an equivalent key on an internal node and we can't have multiple equivalent keys for the lookup key.

PiperOrigin-RevId: 346685656 -- 4ccd41c48f1a83cfa20b3ea534f743dd7d788376 by Abseil Team <absl-team@google.com>: Move CordRep Ref() and Unref() logic into cord_internal.h This change moves Ref() and Unref() logic out of cord.cc into cord_internal. 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.

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.

Linear search was used previously for arithmetic types with `key_compare` of `std::greater` or `std::less`.

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.

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.

This field isn't read after the first iteration in rebalance_after_delete, and I think it's not a correctness issue, but it is read in try_merge_or_rebalance and potentially affects rebalancing decisions so it can affect performance. There's also an extremely unlikely potential for undefined behavior due to signed integer overflow since this field is only ever incremented in try_merge_or_rebalance (and position is an int). Basically though, I just don't think it makes sense to have this invalid iterator floating around here.
