For example, this change allows tests to use `EXPECT_THAT(cord.Chunks(), ElementsAre(...))` PiperOrigin-RevId: 406941278 -- 0c195f073632e21d9a4bce158047b2ba8551c2d1 by Evan Brown <ezb@google.com>: Use explicit exponential growth in SubstituteAndAppendArray.

PiperOrigin-RevId: 406891665 -- c9cff43d4c0568ed01f2fca0f6ef038ae03112b5 by Martijn Vels <mvels@google.com>: Add 'Rebuild' logic to CordRepBtree There are btree hostile scenarios where an application could perform repeated split/insert/merge operations on a cord leading to a tree exceeding the maximum height. While this should be rare in practice, this change adds a Rebuild() method that will rebuild a tree with a 100% fill factor, and we will invoke this rebuild when a tree exceeds the maximum height. This basically follows the similar 'balance' logic in Concat trees (although the latter is common in Concat uses) PiperOrigin-RevId: 406875739 -- 5b2b8fb88f1ebfdc1c670088152da2cb2ea4c376 by Martijn Vels <mvels@google.com>: Add 'in place' enabled RemoveSuffix An in-place RemoveSuffix is more efficient than SubTree() as it can directly modify privately owned nodes and flats allowing easy re-use of free capacity in right-most flats that may turn into Substring edges when using SubTree. PiperOrigin-RevId: 406431230 -- f09903c0a3d7344f59aaf1380a16ea10829217d4 by Derek Mauro <dmauro@google.com>: Internal change PiperOrigin-RevId: 406430373 -- 9957af575c33bb18dc170572a4ee8cc5901df6b2 by Greg Falcon <gfalcon@google.com>: Initial groundwork to allow storing checksum data inside CordRep instances. This uses a RefcountAndFlags bit that was reserved for this purpose, and will be leveraged in a follow-up change to allow attaching checksums to a Cord's value. This change splits RefcountAndFlags::IsOne() into two distinct operations: * IsOne(): This returns true when the associated CordRep is not shared with other threads. This is useful for functions that consume CordRep instances; for example, code that consumes an unshared CordRep can assume ownership of its children without modifying those refcounts. * IsMutable(): This returns true when the associated CordRep reference is not shared with other threads, *and* does not store an associated checksum value. This is useful for functions that modify a CordRep's contents: code may modify the bytes of a mutable-unshared CordRep without fear of races with other threads, or of invalidating a stored checksum. The tricky part of this CL is ensuring that the correct choice between IsMutable() and IsOne() was made at each point. An incorrect application of IsOne() could lead to correctness bugs in the future. Code conditioned on IsOne() may delete the CordRep in question, or assume ownership of its children, but must not modify the CordRep's data without explicitly adjusting the CRC.

The Cord Btree implementation has been extensively tested by google. This changes makes the Cord Btree implementation the default implementation. This change should have no impact on current use cases and does not effect any public API or behavior.

Also rename the increasingly-inaccurately named "Refcount" class to "RefcountAndFlags". In optimized builds, this adds an extra mask instruction to decrement and test operations, but no new branches. Future flags can be added at no extra cost. Each additional flag will of course reduce the range of our refcount, but even with the bit added, we still support refcounts of 500 million.

Instead, simply index different bytes in the AES round function. This requires byte swapping the te{0..3} lookup tables, but it produces an 8% speedup on my Xeon W-2135.

Also, add some consts, avoid an auto, and use lambda capture by value instead of reference. I realized that the compiler can already optimize this - https://godbolt.org/z/Wxd9c4TfK, but I think this way makes the code a bit clearer.

PiperOrigin-RevId: 382858259 -- 20db116f28469149d10e0f7f8b976cb903dd4879 by Gennadiy Rozental <rogeeff@google.com>: Add benchmark running on multiple flags.

PiperOrigin-RevId: 382820341 -- 2e097ad3811c4e329f75b98877a5e74c1d3d84fd by Abseil Team <absl-team@google.com>: Avoid 64x64->128 multiplication in absl::Hash's mix on AArch64 On AArch64, calculating a 128-bit product is inefficient, because it requires a sequence of two instructions to calculate the upper and lower halves of the result. So calculate a 64-bit product instead. Making MultType 64-bits means the upper 32 bits of the result do not participate in shift/xor, but the add/multiply gives us sufficient mixing.

If we add support for non-power-of-two-minus-one capacities, this is the correct thing to assert. For example, consider: Group::kWidth = 8, capacity_ = 8, ctrl_ = {kEmpty, 1, 2, 3, 4, 5, 6, 7, kSentinel, kEmpty, 1, 2, 3, 4, 5, 6}. In this case, if we do an unsuccessful lookup with H2 mapping to slot 1, then the first Group will contain {1, 2, 3, 4, 5, 6, 7, kSentinel} so we need to continue to the second Group (at which point seq.index() == 8 == capacity_) to find a kEmpty. Note: this is a no-op change for now since we never have `capacity % Group::kWidth == 0`.

Especially in the ring and btree alternative code, there is a common check if a node is a 'plain' edge (EXTERNAL or FLAT), or 'something else'. This change can make that check a single branch, i.e., instead of 'tag == EXTERNAL || tag >= FLAT', we can simply check for 'tag >= EXTERNAL'. Likewise we have some cases where we check for RING, EXTERNAL or FLAT, so we align RING + 1 with EXTERNAL.

The subsequent cast to int discards the excess precision. However, the cast may examine the excess precision during conversion, producing surprising results like static_cast<int>(1.7 * 10) == 16 on certain systems. Correct this case by explicitly rounding 1.7 * 10 before casting it.

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.

Single characters are more efficient to search for. Extending this API allows the abseil-string-find-str-contains Clang Tidy to include this pattern. The C++ committee has adopted http://wg21.link/P1679 for inclusion in C++23.

Due to the per-process randomization of the seed used by absl::Hash, users should not notice this change, other than possibly getting better performance. This change only affects platforms where absl::uint128 is implemented with an intrinsic (and where sizeof(size_t)==8) since Wyhash relies on fast 128-bit multiplication for speed.

This change separates static flag value type identification from the type specific "vtable" with all the operations specific to value type. This change allows us to do the following: * We can move most of "vtable" implementation from handle header, which will become public soon, into implementation details of Abseil Flag. * We can combine back marshalling ops and general ops into a single vtable routine. They were split previously to facilitate type identification without requiring marshalling routines to be exposed in header. * We do not need to store two vtable pointers. We can now store only one. The static type id can be deduced on request. Overall we are saving 24 bytes per flag according to size_tester run.
