* Fix C++17 constexpr storage deprecation warningsGravatar Derek Mauro2022-06-09
| | | | | | | | | | | | | | | | | | | This change introduces the symbol ABSL_INTERNAL_NEED_REDUNDANT_CONSTEXPR_DECL to guard redundant declarations of static constexpr data members that are needed prior to C++17. This change also introduces the symbol ABSL_INTERNAL_CPLUSPLUS_LANG, which is supposed to be set to the same value as __cplusplus, except it uses _MSVC_LANG on MSVC so that the value is correct on MSVC. Neither of these new symbols should be used outside of Abseil. Fixes #1191 PiperOrigin-RevId: 453923908 Change-Id: I1316c52c19fa0c168b93cced0c817e4cb7c9c862

| | | | | | | A few targets were missing `linkopts = ...` and so were not obeying the project-wide default settings. Omit any changes to cctz for now, because it's vendored from another project.

* Release absl::CordBufferGravatar Derek Mauro2022-06-06
| | | | | | | | | absl::CordBuffer holds data for eventual inclusion within an existing absl::Cord. CordBuffers are useful for building large Cords that may require custom allocation of its associated memory, a pattern that is common in zero-copy APIs.

PiperOrigin-RevId: 416345422 -- 6399f4f6ae05ebcd67664ebd844902f699ab8ec7 by Abseil Team <absl-team@google.com>: Correct the computation of contention cycles Currently, we record contention cycles from the first time a thread started waiting on a mutex. Consider a situation in which two threads, T1 and T2, run a loop at the top of which they acquire a common mutex and release it at the end of the loop body. Further assume that T2 is never able to acquire the mutex as T1 repeatedly acquires and then releases the mutex. In this case, we would expect that the reported contention cycles would be increase linearly over time. But currently we observe a quadratic behavior in the reported waiting time as mentioned in b/14684244#comment10. To fix the issue, this CL records the contention cycles experienced by all the threads woken up when the mutex is released. Further, contention_start_cycles is set to the current time since the contention cycles for the time already passed has been taken into account. With this CL, we get a linear increase in the waiting time, the expected behavior.

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.

Before XCode 12.5, the availability declarations incorrectly excluded one release on which the features were in fact available. This was corrected in https://github.com/llvm/llvm-project/commit/7fb40e1569dd66292b647f4501b85517e9247953 Unfortunately, we cannot simply switch abseil to the corrected versions, as that will cause build failures when using the older XCode toolchain.

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.
