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.

* cmake: add ABSL_BUILD_TESTING option (#1057)Gravatar Matt Armstrong2021-12-10
| | | | | | | | | | | | | | | | | | | | | Abseil's own tests now are disabled if either BUILD_TESTING or a new option called ABSL_BUILD_TESTING is false. Additionally, Abseil's CMakeLists.txt no longer re-declares the BUILD_TESTING option with a value of false. Abseil had been using just the BUILD_TESTING option, since the fix for #901. Because setting BUILD_TESTING false still works to disable Abseil's tests, this change preserves the behavior asked for in that issue. Previous to that, Abseil had a project specific flag for this, as is the typical idiom used in other projects. The issue with BUILD_TESTING is that it is an all-or-nothing policy. When Abseil is incorporated as a subproject, the encompasing project has no convenient way to enable its own tests while disabling Abseil's. Fixes #1056

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.

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.
