PiperOrigin-RevId: 371362181 -- 5d736accdff04db0e722f377c0d79f2d3ed53263 by Martijn Vels <mvels@google.com>: Fix the estimated memory size for CordRepExternal PiperOrigin-RevId: 371350380 -- eaaa1d8a167aeca67a2aa3a098a2b61a9d72172f by Martijn Vels <mvels@google.com>: Remove flakes by not enforcing re-allocated pointers do never match original Tests that do multiple updates could end up with the original allocated pointer on a 2nd resize, so the 'EqIfPrivate' should not assume that if we do 'not' have the capacity that all following relocations will never match the original. We only care about 'pointer unchanged if private and there is capacity', trying to establish 'pointer changed at some point due to re-allocation; is pointless. PiperOrigin-RevId: 371338965 -- d1837bee6bade1902b095c1cbf64231668bb84c5 by Martijn Vels <mvels@google.com>: Undo inline of small data copy in cord This leads to a performance regression as the code is not inlined (absent hard FDO inputs), and there are no suitable tail call options. PiperOrigin-RevId: 371332332 -- 06dc64b833069efc7d18b11df607c8c22be690da by Martijn Vels <mvels@google.com>: Add final instrumentation for Cordz and remove 'old' cordz logic. This change instruments the last cord function for cordz. It removes the 'old' functions: set_tree, replace_tree, UpdateCordzStatistics and RecordMetrics. PiperOrigin-RevId: 371219909 -- a5e0be538579c603052feec03e6d9910c43ea787 by Martijn Vels <mvels@google.com>: Extend the life of CordRep* if inside a snapshot If a snapshot (potentially) includes the current CordzInfo, we need to extent the lifetime of the CordRep*, as the snapshot 'point in time' observation of the cord should ideally be preserved. PiperOrigin-RevId: 371146151 -- 74d77a89774cd6c8ecdeebee0193b294a39383d6 by Martijn Vels <mvels@google.com>: Instrument std::string consuming methods: ctor, operator=, Append and Prepend This change moves the 'steal into CordRep' logic into a separate function so we can use it directly in the ctor, operator assign and append and prepend, allowing Cordz instrumentation with the proper method attributes. The assign operator is implemented in AssignLargeString leaving the dispatch inlined in cord.h (which as a side effects also allows clean tail calls in the AssignLargeString method) PiperOrigin-RevId: 371094756 -- b39effc45266b7ce2e7f96caa3b16cb6e3acc2dd by Martijn Vels <mvels@google.com>: Add Cordz instrumentation to CordReader PiperOrigin-RevId: 370990181 GitOrigin-RevId: 60b8e77be4bab1bbd3b4c3b70054879229634511 Change-Id: I96af62e6f1a643e8b1228ae01e6c84e33706bb05

This hardens the implementation against ODR violations where info pointers are crossing dynamic library boundaries which are privately loaded. PiperOrigin-RevId: 370673045 -- 712dba768e66ee2ba85d6010829c617cd2af6ba7 by Martijn Vels <mvels@google.com>: Intrument Cord::operator= for Cordz PiperOrigin-RevId: 370659149 -- c0b347a2289e151b72680269332e264b8fa989c0 by Matt Kulukundis <kfm@google.com>: Fix test guards for ABSL_ATTRIBUTE_RETURNS_NONNULL PiperOrigin-RevId: 370594807 -- c2bedaa3472ef223f907de2604f9b9b58852ec5f by Martijn Vels <mvels@google.com>: Add new Cordz instrumentation on GetAppendRegion.

PiperOrigin-RevId: 369968167 -- 21092b889fad34ec605894e311b436d5f417456f by Benjamin Barenblat <bbaren@google.com>: Round floats using round(x), not static_cast<int>(x + 0.5) Adding 0.5 to an IEEE float may cause one bit of precision loss, which is enough to change the result in certain cases. For example, static_cast<int>(std::round(0.49999999999999994)) == 0 static_cast<int>(0.49999999999999994 + 0.5) == 1 PiperOrigin-RevId: 369926519 GitOrigin-RevId: f825cf3feb6db06522b2b4ee785de7dfa325780d Change-Id: Ib78ce1faec79f06578933db5dc6fc05de043ead1

PiperOrigin-RevId: 295161959 -- 6018c57f43c45c31dc1a61c0cd75fa2aa9be8dab by Gennadiy Rozental <rogeeff@google.com>: Introduce independent notion of FlagStaticTypeID. 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.
