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) PiperOrigin-RevId: 363566934 -- e00e971a2de3138861f5e1900201c9cc7788f714 by Laramie Leavitt <lar@google.com>: Add a non-compile test to absl::BitGenRef for temporaries. PiperOrigin-RevId: 363437284 -- 3685644ec115d99789de32aceb76c32a00756fea by Derek Mauro <dmauro@google.com>: Make OSS code consistent with internal code by using the forward declaration of absl::Status that contains ABSL_MUST_USE_RESULT. PiperOrigin-RevId: 363426906 -- b85fec142c3aa3f632fa985f9f8f73a253819723 by Evan Brown <ezb@google.com>: Move raw_hash_set::infoz_ into raw_hash_set::settings_. This reduces the size of raw_hash_sets by alignof(size_t) bytes when hashtablez is disabled. PiperOrigin-RevId: 363034264 -- c6fde3b17e5845191eb8b2bfc1760c8bfb9573ff by Mark Barolak <mbar@google.com>: Internal change PiperOrigin-RevId: 362990378 -- 81713cf964905b43d1cbe32ce5fed97539029625 by Abseil Team <absl-team@google.com>: Fix typo in comment (execeptions -> exceptions). PiperOrigin-RevId: 362946191 -- 3ee92ca470feca44da417b03ee45a915c6eb5155 by Abseil Team <absl-team@google.com>: Add absl::FindAndReportLeaks and routes it to the corresponding __lsan_do_recoverable_leak_check. PiperOrigin-RevId: 362622199 -- b95b7194b20e02c20d72289fbc79a0d35b82e256 by Abseil Team <absl-team@google.com>: Add `kWithEverything` to StatusToStringMode PiperOrigin-RevId: 362595218 -- 0a960d96a0014eab7e1c55b479269450ed8e98d7 by Abseil Team <absl-team@google.com>: 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. PiperOrigin-RevId: 362557420 -- 2ac5ea212c150afd2f58025a5cab8c45d16949c6 by Abseil Team <absl-team@google.com>: Change variable name 'slots' to 'slot_count' to avoid name-clash with Qt builds. PiperOrigin-RevId: 362556289 -- 934f0f409c9c548716a46363d6e243406fad4028 by Mark Barolak <mbar@google.com>: Clarify the comment on ABSL_CACHELINE_SIZE to indicate that the macro definition itself shouldn't change, but rather that call sites should change when possible. This addresses the request for improved documentation in https://github.com/abseil/abseil-cpp/pull/842.

Simpler fast path for push_back/emplace_back. 2. Do not inline slow path of push-back/emplace_back. 3. Simplify resize implementation. Performance: A simple benchmark that does the following per iteration: ``` push_back on an InlinedVector<int64> push_back on an InlinedVector<bool> ``` Sees iteration time go from 4.3ns to 2.8ns and code size shrink from 1129 bytes to 175 bytes.

This is suboptimal: https://screenshot.googleplex.com/5HqDuFBKUEqrVgy. Relevant Benchmarks: ``` BM_StatusCopyError_Deep/threads:1 26.9ns ±13% 21.2ns ±16% -21.46% (p=0.000 n=15+15) BM_StatusCopyError_Deep/threads:2 32.0ns ±30% 25.6ns ±37% -20.17% (p=0.004 n=15+14) BM_StatusCopyError_Deep/threads:4 37.4ns ±84% 30.6ns ±58% -18.26% (p=0.029 n=15+15) BM_StatusCopyError_Deep/threads:8 47.2ns ±33% 33.5ns ±56% -28.91% (p=0.000 n=15+14) ``` PiperOrigin-RevId: 343303312 -- 2f9d945654292e8e52cad410fa41dae794cff42c by Abseil Team <absl-team@google.com>: Set SOVERSION for the installed libraries PiperOrigin-RevId: 343287682 -- 600bbfffe91cfbdc60b43cdad5619258298d0b0d by Abseil Team <absl-team@google.com>: Fix a typo in a comment (than -> that) PiperOrigin-RevId: 343187724 -- 310c82cd97b3f1f0d1ee93a0ee2b0aee828b2a93 by Abseil Team <absl-team@google.com>: Simplify unaligned memory access functions. The #ifdef to produce calls to __sanitizer_unaligned_load16 etc were needed in past versions of this code, when we were lying to the compiler about the alignment of the loads/stores, by using a reinterpret_cast. However, a year ago, absl switched to simply use memcpy. Sanitizers support this correctly by default, nothing extra is required. PiperOrigin-RevId: 343159883 -- bdf6fcf99180c371fda6ba8af82fd44656e372fa by Gennadiy Rozental <rogeeff@google.com>: Migrate usage flags to global variables instead of modeling them as Abseil Flags. Also introduce new semantic for --help=substring command line argument.

Only initialize the string storage when needed. This makes StrSplit() 0-30% faster depending on the use case.

PiperOrigin-RevId: 333159251 -- 461640476dab1726eba8d26a0c8012b5a35ba0b1 by Evan Brown <ezb@google.com>: Avoid relying on mutable b-tree set iterators in merge(). Mutable set iterators is an API difference from std::set that we want to get rid of. Also remove a superfluous `public` member specification in btree_container. PiperOrigin-RevId: 333101335 -- 96cf8ac6946840be17da445739c950fd237159f4 by Abseil Team <absl-team@google.com>: Explicitly mention that FormatDuration deviates from Go for the zero duration PiperOrigin-RevId: 333094962 -- 83389040371436aab4e952211e98ffa98e24fd94 by Abseil Team <absl-team@google.com>: Internal change.

PiperOrigin-RevId: 329523785 -- 79e5018dba2e117ad89b76367165a604b3f24045 by Abseil Team <absl-team@google.com>: Record rehash count in hashtablez This will help identify which containers could benefit from a reserve call. PiperOrigin-RevId: 329510552 -- e327e54b805d67556f934fa7f7dc2d4e72fa066a by Abseil Team <absl-team@google.com>: Fix -Wsign-compare issues. These lines could theoretically have overflowed in cases of very large stack traces etc. Very unlikely, but this was causing warnings when built with -Wsign-compare, which we intend to enable with Chromium. In none of these three cases is it trivial to switch to a range-based for loop.

-- 0c8282d75798c77733eee6167870bcc6acc0bfc1 by Evan Brown <ezb@google.com>: Provide mutable access to the key in node handles using std::launder when compiled with C++17 or later. Also, document why we can't provide mutable access to the key without C++17. Note: we use Policy::mutable_key() because btree already uses Policy::key() internally to get const key access, and we want to avoid calling std::launder unless we need mutable access to the key. PiperOrigin-RevId: 326519000 -- 8018d0c3044400f0a731b0d2d00b606742c98818 by Xiaoyi Zhang <zhangxy@google.com>: Move `Status` internal symbols from the public header into an internal header file. PiperOrigin-RevId: 326471847 -- 87a7644864ba7c003b0611898aaba1b71c840376 by Abseil Team <absl-team@google.com>: Avoid a costly divide (the division accounts for 10% of the time spent in the function). When the division is signed, the compiler has to generate a div. When it is unsigned, it can generate a shift: https://godbolt.org/z/vGfTv4. As per the test above the div, we know that the value is unsigned.
