PiperOrigin-RevId: 428076422 -- 6a90d18477cc3a6de84282b6e38d6f294aa72748 by Evan Brown <ezb@google.com>: In sanitizer mode, add generation integers to b-tree nodes and iterators and validate that iterators have not been invalidated already when they're used. Even though generation integers are stored in all nodes, we only use the one stored in the root node for validation. The reason we keep one in all the nodes is that nodes can become a root node after they are allocated. Also change the order of args in init_leaf to not violate the style guide. PiperOrigin-RevId: 428054226 -- ede4a0f676f43e7003fd2599c263d55222e760ba by Martijn Vels <mvels@google.com>: Physically remove CordRepConcat This CL removes all uses of CordRepConcat. This change is executed by removing all the dead 'btree_enabled()' and 'IsConcat' branches, and all subsequent dead code. This change explicitly does not optimize any of the remaining code other than the most trivial ones such as removing 'stack' loop vars and loops. PiperOrigin-RevId: 428002308 -- 7cc83d96118149cf1aa1258a066b8fd4517df5f6 by Evan Brown <ezb@google.com>: Change btree_iterator from a struct to a class. Motivation: btree_iterator has private members and invariants so it should be a class. Also merge two private sections.

This change removes CordRepConcat creation, issuing a FATAL errors on the (practically impossible) call path on broken invariants. This change is deliberately limited in impact, subsequent changes will be more voluminous ripping out the (now dead) CordRepConcat code. PiperOrigin-RevId: 427741022 -- e21eb354c1bb358ea8b64d0e3fbb378e87b8b8c4 by Derek Mauro <dmauro@google.com>: Update the implementation of ABSL_DEPRECATED to work with GCC, and recommend using the standard attribute [[deprecated]] for C++14 and newer GCC users that are experiencing new warnings can silence them with -Wno-deprecated-declatations.

Abseil Team	9336be04a2	Export of internal Abseil changes -- e7f53dfbf809812e84770217777f81b6308a3084 by Abseil Team <absl-team@google.com>: Add a parameter pack to absl profile to allow profiles to separate dynamic data from static data that is available at constructor-time. Background: `inline_element_size` is effectively constant, but there is a data race between its initialization and its access. We had fixed that race by making inline_element_size atomic. This CL changes `inline_element_size` back to a non-atomic integer, and provides a way for all profiles to provide Register()-time values. PiperOrigin-RevId: 413960559 -- 70234c5943f8e37e17c1d9c54d8ed61d39880abf by Chris Kennelly <ckennelly@google.com>: Document that absl::FunctionRef does not allocate.

PiperOrigin-RevId: 410557900 -- 4732289bf4b56123fed113e36be4710b55c6a6c7 by Greg Falcon <gfalcon@google.com>: Improve the quality of absl::Hash<std::vector<bool>>. This previously dispatched to std::hash<vector<bool>>, which suffers from trivial collisions on many platforms. (They often hash the internal words but no size info, so that, e.g., {1, 1} and {1, 1, 0} collide.) Also extended the unit test to exercise this.

We no longer need the API requirement that alignof(Releaser) <= (default `::operator new` alignment). Also remove another static_assert from a TODO in cord_internal.h and fix some warnings about calling std::move on a forwarding reference.

Abseil Team	768eb2ca28	Export of internal Abseil changes -- f012012ef78234a6a4585321b67d7b7c92ebc266 by Laramie Leavitt <lar@google.com>: Slight restructuring of absl/random/internal randen implementation. Convert round-keys.inc into randen_round_keys.cc file. Consistently use a 128-bit pointer type for internal method parameters. This allows simpler pointer arithmetic in C++ & permits removal of some constants and casts. Remove some redundancy in comments & constexpr variables. Specifically, all references to Randen algorithm parameters use RandenTraits; duplication in RandenSlow removed.

PiperOrigin-RevId: 311844448 -- bdbe6b5b29791dbc3816ada1828458b3010ff1e9 by Laramie Leavitt <lar@google.com>: Change many distribution tests to use pcg_engine as a deterministic source of entropy. 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	5 years ago
