Abseil Team	7ba826e50d	Export of internal Abseil changes -- 5f3c139695d5c497ca030e95a607537a7be7caa7 by Benjamin Barenblat <bbaren@google.com>: Don’t examine irrelevant destination buckets in DiscreteDistributionTest Abseil generates discrete distributions using Walker’s aliasing algorithm. 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.

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: 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.

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.

PiperOrigin-RevId: 321583786 -- 99c6d300b17f186c28867b08cc79f1e55077e88a by Evan Brown <ezb@google.com>: Code simplification: consolidate methods to erase values/nodes. Motivation: this will make floating storage work simpler. - Delete erase_same_node/erase_from_leaf_node/remove_value/remove_values_ignore_children. - Move node deletion methods inside btree_node. - Delete three-argument move() and use transfer_n() instead. - Note: there's still one usage of move (in btree::erase(iterator)) that could use transfer, but I think doing so would add more complexity than it's worth. PiperOrigin-RevId: 321407673 -- c3efed6c1763190c6b3bccbede9b2989ab21b258 by Evan Brown <ezb@google.com>: Support heterogeneous insert_or_assign, try_emplace, operator[] for btree_map. Also do a bit of cleanup: - Add _impl methods for insert_or_assign/try_emplace. - Rename some hint iterator params from `position` to `hint`.

PiperOrigin-RevId: 316963065 -- 4d475b5ad02d41057447d722ad35573fc4f48d1f by Evan Brown <ezb@google.com>: Small fix to previous change: the first overload of insert_iterator_unique wasn't actually being selected. Fix that issue and add tests to verify that it actually works. Note: couldn't use TestInstanceTracker here because that counts instances (and decrements in destructor) rather than counting all constructor calls.

Also, move it out of the template to avoid printing the whole template instantiation as part of the assertion. It is not relevant and can significantly bloat the error message and hide the important bits.

Convert round-keys.inc into randen_round_keys.cc file. Consistently use a 128-bit pointer type for internal method parameters. This allows simpler pointer arithmetic in C++ & permits removal of some constants and casts. Remove some redundancy in comments & constexpr variables. Specifically, all references to Randen algorithm parameters use RandenTraits; duplication in RandenSlow removed.

PiperOrigin-RevId: 311844448 -- bdbe6b5b29791dbc3816ada1828458b3010ff1e9 by Laramie Leavitt <lar@google.com>: Change many distribution tests to use pcg_engine as a deterministic source of entropy. 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	5 years ago
