-- e1a0989213908927f05002ab7697955ad7dc5632 by Martijn Vels <mvels@google.com>: Introduce CordRepBtreeReader CordRepBtreeReader provides forward navigation on cord btrees with absolute positional (offset) context, iterating over btree data in absl::string_view chunks. PiperOrigin-RevId: 387585161 -- 206d298e2bccb998731995cb05717b31fa9d90ec by Abseil Team <absl-team@google.com>: Internal change PiperOrigin-RevId: 387577465 -- f07fafe8a400a4f5dfef186d1a3b61fb7f709fe5 by Abseil Team <absl-team@google.com>: This change adds debug-build enforcement that the inputs to absl::c_set_intersection are sorted, which is a prerequisite of std::set_intersection and required for correct operation of the algorithm. PiperOrigin-RevId: 387446657 -- 2ca15c6361bb758be7fb88cae82bf8489b4d3364 by Abseil Team <absl-team@google.com>: Change BadStatusOrAccess::what() to contain status_.ToString() This ensures that on uncaught exception propagation that would cause program termination, the message contains information on the error which caused the failure. Lazy initialization of what_ is a value judgement: if most callers are expected to call status() not what(), lazy initialization is correct. If most callers are expected to call what(), it should be initialized on construction to avoid atomic operation overhead. PiperOrigin-RevId: 387402243 -- 3e855084e104dc972a0c4385395e6d8e8465127f by Gennadiy Rozental <rogeeff@google.com>: LSC: Standardize access to GoogleTest flags on GTEST_FLAG_GET/GTEST_FLAG_SET This change is necessary to move Googletest flags out of the testing:: namespace without breaking code. These new macros will continue to be required for code that needs to work both inside Google's monorepo and outside in OSS, but can be used anywhere inside the monorepo.

-- 69b5d0b2a5adb49a53e51f9da6848eaa484242fe by Derek Mauro <dmauro@google.com>: Changes the absl::Duration factory functions to disallow types that are convertible to int or double, instead requiring that the argument itself is indeed an integer or a floating-point number. This will prevent callers from passing arguments, such as std::atomic<T>. This change is an API break. Information and a tool to fix issues can be found at https://abseil.io/docs/cpp/tools/upgrades/duration-conversions PiperOrigin-RevId: 387153494 -- 786063e438ab6a55ac4baa88ad4d20a8293be52a by Evan Brown <ezb@google.com>: Make ctrl_t be an enum class. This adds type safety, and also when strict aliasing is enabled, the compiler will know that control bytes can't alias non-control bytes. Also make H2() return h2_t. PiperOrigin-RevId: 387120717 -- 7e537aabec1c255d6e7c9d21232c597c1c2077bf by Evan Brown <ezb@google.com>: Add some missing `const` keywords to ctrl_t* function parameters. PiperOrigin-RevId: 386976062 -- da53ac6d91cabd951e81dd0a145e1e52b918955f by Martijn Vels <mvels@google.com>: Change Seek and InitOffset to return nullptr instead of assert / fail. This makes it consistent with the rest of the API (Next, Previous, Skip) and hardens it against invariants that are harder (or less likey) to be upheld correctly by the caller. PiperOrigin-RevId: 386963283 -- a4d1faac020d5025edf53ce81808e5db68da7d89 by Abseil Team <absl-team@google.com>: PC / Backtrace / Symbolization for Emscripten.

PiperOrigin-RevId: 382858259 -- 20db116f28469149d10e0f7f8b976cb903dd4879 by Gennadiy Rozental <rogeeff@google.com>: Add benchmark running on multiple flags. Update size_tester to include cost of absl::GetFlag call. Add size_tester invocation for bool flag. New benchmark better represent GetFlag usage. 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. PiperOrigin-RevId: 382625931 -- f3ae3f32cb53168c8dc91b766f2932dc87cec503 by Abseil Team <absl-team@google.com>: Remove homegrown Round implementation absl/time/duration.cc defined a Round implementation to accommodate old versions of MSVC that lacked std::round(long double). Abseil no longer supports those MSVCs, so we don’t need the homegrown implementation anymore. Remove it, and replace calls to it with std::rint. PiperOrigin-RevId: 382605191 -- a13631c91bf5478289e1a512ce215c85501a26f7 by Martijn Vels <mvels@google.com>: Move the Consume() conversion functions out of cord_rep_ring into cord_rep_consume. This makes these functions generic, so we can repurpose these for the new Btree conversion functions. PiperOrigin-RevId: 382594902 -- 7394c737500c2d8371fcf913b21ad1b321ba499d by Benjamin Barenblat <bbaren@google.com>: Remove homegrown Round implementation absl/time/duration.cc defined a Round implementation to accommodate old versions of MSVC that lacked std::round(long double).

It needs a different header, so I've separated it out from the GLIBC check above. PiperOrigin-RevId: 382332475 -- 74e261dbb467741b2ddd8b490e04c531fdd2f559 by Martijn Vels <mvels@google.com>: Add BTREE tag for CordRepNode implementing a Btree cord. This change only forward declared the CordRepBtree class (not implemented yet) and defines the enum value BTREE. While RING and BTREE should never co-exist, we define a new value for BTREE so as not to make transitioning between RING and BTREE harder than it needs to be. This changes shifts the FLAT value / computation from FLAT = 4 to FLAT =5 PiperOrigin-RevId: 382326710 GitOrigin-RevId: 1620e8ffaa93ef24510ca60c7fff2a07248ac9f6 Change-Id: Ia8f99dde3874808f56062bd37ab3e63764099734 |

PiperOrigin-RevId: 381276748 -- da32624792d2948fe83d0ce58794d505799ab5d0 by Benjamin Barenblat <bbaren@google.com>: s/round/rint/ in exponential_biased `rint` differs from `round` in that it uses the current FPU rounding mode. It’s thus potentially faster, since it doesn’t have to save and restore FPU state. It also is more reflective of developer intent – most developers expect all FPU operations to use the current rounding mode, and having exponential_biased follow that rule seems ideal.

Identify tests that are sensitive to the x87, and skip them when we’re on 32-bit Intel.

Change Cord constructor(string_view) to explicit make_tree and Cordz tracking
This CL changes the ctor to use an easier to maintain model where Cord code explicitly invokes Cordz update or new / tree logic, which avoids the ambiguity of the 'branched' InlineRep::set_tree code. This removes the need to equip InlineRep with 'MethodIdentifier' or other necessary call info, and also is a cleaner model: InlineRep is carrying too much code now that should plainly sit in Cord, especially with all internal abstractions having moved to InlineData.

771d81ed357496c117179e1daec76eba5155932d by Martijn Vels <mvels@google.com>:
Replace mutex() with Lock() / Unlock() function
Mini design future tracking of CordzInfo sampled cords: CordzInfo holds a CordRep* reference without a reference count. Cord is responsible for synchronizing updates for sampled cords such that the CordRep* contained in CordzInfo is at all times valid. This is done by scoping Lock() and Unlock() calls around the code modifying the code of a sampled cord. For example (using the future CL CordzUpdateScope()):
CordzInfo* cordz_info = get_cordz_info();
CordzUpdateScope scope(cordz_info, CordzUpdateTracker::kRemovePrefix);
CordRep* rep = RemovePrefixImpl(root);
set_tree(rep);
if (cordz_info) {
cordz_info->SetCordRep(rep);
}
On CordzInfo::Unlock(), if the internal rep is null, the cord is no longer sampled, and CordzInfo will be deleted. Thus any update resulting in the Cord being inlined will automatically no longer be sampled.

Correct Thumb function bound computation in the symbolizer
On 32-bit ARM, all functions are aligned to multiples of two bytes, and
the lowest-order bit in a function’s address is ignored by the CPU when
computing branch targets. That bit is still present in instructions and
ELF symbol tables, though; it’s repurposed to indicate whether the
function contains ARM or Thumb code. If the symbolizer doesn’t ignore
that bit, it will believe Thumb functions have boundaries that are off
by one byte, so instruct the symbolizer to null out the lowest-order bit
after retrieving it from the symbol table.

This change adds a `rep` property to CordzInfo, which is intended to be used by collection logic. Mini design: Cord invokes TrackCord() providing the active 'root' cordrep of the newly sampled Cord, returning a CordzInfo with a weak (uncounted) reference to this root. Cord invokes `SetCordRep()` each time the root cordrep of the sampled Cord is updated while holding `mutex()`. Cord must also obtain `mutex()` _before_ removing a reference on the old root. i.e.: Cord must guarantee that the (weak) reference held in CordzInfo is at all times valid. CordzInfo collection code can then safely obtain a (reference counted) rep pointer by adding a reference to `rep_` while holding `mutex()`. This requires only a very brief critical section inside CordzInfo logic, minimizing contention with concurrent Cord updates. Cord code should typically obtain and hold `mutex()` for the entirety of each mutating Cord operation on a sampled cord. As Cord is thread compatible, it never competes on the lock with any other thread. The only possible concurrent access is from Cordz collection code, which should be a relatively rare event.

This benchmark has significantly different possible behaviors that can result in misleading metrics. Specifically, we can have a case where we are deallocating the last node in the b-tree in the erase and then allocating a new node in the insert call repeatedly, whereas normally, we end up just inserting/erasing a value from the last node. Also, the name of the benchmark is misleading because it involves an erase and an insert, but the name only mentions the insert.

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.

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 |
