-- 0db7f4046f9b59c0f8c3df2f0eb7fd88fc328439 by Abseil Team <absl-team@google.com>: Revise documentation of bit_cast: * Removes inappropriate examples (round-tripping pointers, serialization), for which reinterpret_cast is more appropriate. * Removes mention of "bit representation", which is not an explicit notion in C++. The best we get is "byte representation". * Removes a circular defition of "bitcast" as itself, and instead explains what it does. * Removes the mathism "for some values of", which is probably not totally accessible to a general audience, and in any case needless verbiage. * Fixes comments in the example. * Replaces some colloquialisms with simpler, more direct language.

Prevent compiler from optimizing Group_Match* benchmarks away.
Currently we benchmark single store of precomputed value.
Not all affected benchmarks show performance changes:
BM_Group_Match 0.53ns ± 1% 0.53ns ± 0% -0.42% (p=0.038 n=10+10)
BM_Group_MatchEmpty 0.26ns ± 1% 0.26ns ± 1% ~ (p=1.000 n=10+10)
BM_Group_MatchEmptyOrDeleted 0.26ns ± 1% 0.26ns ± 1% ~ (p=0.121 n=10+10)
BM_Group_CountLeadingEmptyOrDeleted 0.26ns ± 1% 0.45ns ± 0% +70.05% (p=0.000 n=10+8)
BM_Group_MatchFirstEmptyOrDeleted 0.26ns ± 0% 0.44ns ± 1% +65.91% (p=0.000 n=8+9)
But inspecting the generated code shows the difference,
e. g. BM_Group_MatchFirstEmptyOrDeleted
Before:
add $0xffffffffffffffff,%rbx
jne 30
After:
pcmpeqd %xmm0,%xmm0
pcmpgtb -0x30(%rbp),%xmm0
pmovmskb %xmm0,%eax
add: 0x23$0xffffffffffffffff,%rbx
jne 40

Make Cord::InlineRep::set_data unconditionally zero out memory.
Currently there is a single case where we don't zero out memory
as an optimization. Unconditional zeroing doesn't show any changes
in benchmarks, except for the unrelated improvement:
BM_CordPartialCopyToCord/1M/1 12.6ns ± 4% 12.6ns ± 4% ~ (p=0.857 n=16+19)
BM_CordPartialCopyToCord/1M/128 44.9ns ± 7% 45.0ns ± 3% ~ (p=0.468 n=18+17)
BM_CordPartialCopyToCord/1M/1k 64.5ns ± 4% 61.4ns ± 4% -4.82% (p=0.000 n=19+17)
BM_CordPartialCopyToCord/1M/8k 139ns ± 3% 128ns ±15% -7.76% (p=0.009 n=17+20)
BM_CordPartialCopyToCord/1M/16k 193ns ± 6% 168ns ± 6% -13.17% (p=0.000 n=17+17)
BM_CordPartialCopyToCord/4M/16k 199ns ± 4% 177ns ± 4% -11.36% (p=0.000 n=17+18)
BM_CordPartialCopyToCord/4M/32k 275ns ± 3% 250ns ± 4% -9.00% (p=0.000 n=18+18)
BM_CordPartialCopyToCord/4M/64k 291ns ± 4% 266ns ± 5% -8.53% (p=0.000 n=18+16)
BM_CordPartialCopyToCord/4M/128k 322ns ± 5% 291ns ± 4% -9.43% (p=0.000 n=20+18)
BM_CordPartialCopyToCord/8M/32k 281ns ± 5% 251ns ± 4% -10.38% (p=0.000 n=20+16)
BM_CordPartialCopyToCord/8M/64k 293ns ± 6% 267ns ± 4% -8.87% (p=0.000 n=16+19)
BM_CordPartialCopyToCord/8M/128k 334ns ± 3% 305ns ± 2% -8.56% (p=0.000 n=17+16)
This is clearly an alignmnet effect since number of the executed instructions is the same:
M_CordPartialCopyToCord/1M/1 155 ± 0% 155 ± 0% ~ (all samples are equal)
BM_CordPartialCopyToCord/1M/128 446 ± 0% 446 ± 0% ~ (p=0.332 n=36+39)
BM_CordPartialCopyToCord/1M/1k 473 ± 0% 473 ± 0% ~ (p=0.969 n=40+40)
BM_CordPartialCopyToCord/1M/8k 808 ± 0% 808 ± 0% ~ (p=0.127 n=40+39)
BM_CordPartialCopyToCord/1M/16k 957 ± 0% 957 ± 0% ~ (p=0.532 n=40+40)
BM_CordPartialCopyToCord/4M/16k 952 ± 0% 952 ± 0% ~ (p=0.686 n=39+39)
BM_CordPartialCopyToCord/4M/32k 1.12k ± 0% 1.12k ± 0% ~ (p=0.690 n=40+40)
BM_CordPartialCopyToCord/4M/64k 1.23k ± 0% 1.23k ± 0% ~ (p=0.182 n=40+39)
BM_CordPartialCopyToCord/4M/128k 1.44k ± 0% 1.44k ± 0% ~ (p=0.711 n=40+40)
BM_CordPartialCopyToCord/8M/32k 1.12k ± 0% 1.12k ± 0% ~ (p=0.697 n=40+40)
BM_CordPartialCopyToCord/8M/64k 1.23k ± 0% 1.23k ± 0% +0.00% (p=0.049 n=40+40)
BM_CordPartialCopyToCord/8M/128k 1.44k ± 0% 1.44k ± 0% ~ (p=0.507 n=40+40)
This makes code simpler and doesn't regress performance.

-- e7f53dfbf809812e84770217777f81b6308a3084 by Abseil Team <absl-team@google.com>: Add a parameter pack to absl profile to allow profiles to separate dynamic data from static data that is available at constructor-time. Background: `inline_element_size` is effectively constant, but there is a data race between its initialization and its access. We had fixed that race by making inline_element_size atomic. This CL changes `inline_element_size` back to a non-atomic integer, and provides a way for all profiles to provide Register()-time values.

4732289bf4b56123fed113e36be4710b55c6a6c7 by Greg Falcon <gfalcon@google.com>:
Improve the quality of absl::Hash<std::vector<bool>>.
This previously dispatched to std::hash<vector<bool>>, which suffers from trivial collisions on many platforms. (They often hash the internal words but no size info, so that, e.g., {1, 1} and {1, 1, 0} collide.)
Also extended the unit test to exercise this.

-- 83e4cdf03a4d702b30e69204060de09e462e23c6 by Greg Falcon <gfalcon@google.com>: Revert the crc addition to RefcountAndFlags, and restore related comments to their original state. In development, the implementation of SetExpectedCrc() changed, and there is no longer a need to track the CRC status in the refcount. Since the distinction between IsOne() and IsMutable() is subtle *and unused*, removing it now can help avoid subtle bugs in the future. This distinction can always be added back later, if it proves necessary. Keep the reserved bit for now; all it costs is one extra mask instruction in the refcount checks, and space for extra state in Cord is always hard to find. PiperOrigin-RevId: 408647038 -- ee67585cf66954176615271f50f8b278119dd138 by Greg Falcon <gfalcon@google.com>: Implement Cord::SetExpectedChecksum() and Cord::ExpectedChecksum(). SetExpectedChecksum() will store a uint32_t out-of-band alongside a Cord's data. This value persists through copies and assignments. Mutating operations on a Cord cause the value to be forgotten. ExpectedChecksum() retrieves the stored value, if present. This API is intended for storing a CRC32C checksum alongside data, allowing checksums to be passed through dataflows and validated at the final step. However, this API is agnostic to the meaning of the stored value. No CRC32C validation is performed by these new APIs. This implementation adds a new CordRep node, CordRepCrc. A CordRepCrc may (currently) only live at the top of a tree. This allows traversal logic to be agnostic to these nodes, instead putting the needed branches at the mutation level. This also implements the property requested from API review, that any mutation is guaranteed to permanently forget the stored CRC.

-- 04cb3b22497190170aa5b774e98080c5de2ba60b by Abseil Team <absl-team@google.com>: Alternative bit mixer for LowLevelHash on ARM LowLevelHash's bit-mixer is inefficient on ARM because it calculates a 128-bit product of two 64-bit numbers. On ARM, this requires a sequence of two instructions with a high combined latency and poor throughput. This change provides alternative bit-mixing code for ARM that uses only 64-bit arithmetic (multiplication, xor, and left-shifts) and speeds things up considerably. The bit-mixing code for ARM was inspired by by Woothash[1] and xxh3[1]. Once I landed on a sequence of operations that provided good mixing, I used a test harness to search for the combination of shift / rotate factors that provided the best mixing, as indicated by SMHasher hash quality tests. The new mixing code passes 13 out of 15 of the hash quality test suites in SMHasher, with the two failures being in the noise range: e.g. 1 collision vs. zero expected in a keyset of ~8m keys.

Change the "full table!" asserts in raw_hash_set to use `<= capacity` instead of `< capacity`.
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`.

Change Ring, EXTERNAL and FLAT tag values to be consecutive values
The purpose of this change is to have FLAT = EXTERNAL + 1. 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.

Round a double multiplication before casting it to integer
The code
static_cast<int>(x * y)
(for double x and y) performs a double multiplication into a temporary
that, by standard, may have excess precision. 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.

Big update to LTS release process
* Add create_lts.py script to to the LTS modification
This is simpler than copybara since very few changes are needed
* Use the default installation paths instead of a versioned path.
If a versioned path is needed, this is easy to change on the commandline.
* Make the integration test use the LTS transformed version
* Test both static and dynamic linking (fixes pkg-config dynamic linking)

Accept e.g. ".__uniq" as a valid clone name. 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.

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.

Also add testing for this behavior. PiperOrigin-RevId: 356579041 GitOrigin-RevId: f9476c95cf7625d7b0fc4661f253b0aac4341044 Change-Id: Iadd094d109b4869998f2427319ef66d1cf1e8eff |

-- 0acc8470116819a62fd5ebbc2c64fdd703c93331 by Abseil Team <absl-team@google.com>: Add an attribute to HashtablezInfo which performs a bitwise XOR on all hashes. The purposes of this attribute is to identify if identical hash tables are being created. If we see a large number of identical tables, it's likely the code can be improved by using a common table as opposed to keep rebuilding the same one.
