If a versioned path is needed, this is easy to change on the commandline. * Make the integration test use the LTS transformed version * Test both static and dynamic linking (fixes pkg-config dynamic linking) PiperOrigin-RevId: 363566934 -- e00e971a2de3138861f5e1900201c9cc7788f714 by Laramie Leavitt <lar@google.com>: Add a non-compile test to absl::BitGenRef for temporaries.

Further, bring the implementation on par with libiberty's demangler grammar. Clang introduced option -funique-internal-linkage-names that adds the suffix ".__uniq.[0-9]+" to internal linkage functions to give them a globally unique identifier. The suffix was designed to work with existing demanglers which do recognize a "_" along with the alphanumeric string. This change enhances the demangler to allow "_" with the alphanumeric string. Please refer to libiberty's cp-demangle.c where function d_clone_suffix implements the demangling of clone suffixes : 1. '_' is accepted as a valid character with the alphanumeric sequence. 2. The alphanumberic sequence is optional. 3. The digit sequence is optional.

Allowing NiceMocks reduces the log spam for un-mocked calls, and it enables nicer setup with ON_CALL, so it is desirable to support it in absl::MockingBitGen. Internally, gmock tracks object "strictness" levels using an internal API; in order to achieve the same results we detect when the MockingBitGen is wrapped in a Nice/Naggy/Strict and wrap the internal implementation MockFunction in the same type. This is achieved by providing overloads to the Call() function, and passing the mock object type down into it's own RegisterMock call, where a compile-time check verifies the state and creates the appropriate mock function. PiperOrigin-RevId: 361233484 -- 96186023fabd13d01d32d60d9c7ac4ead1aeb989 by Abseil Team <absl-team@google.com>: Ensure that trivial types are passed by value rather than reference PiperOrigin-RevId: 361217450 -- e1135944835d27f77e8119b8166d8fb6aa25f906 by Evan Brown <ezb@google.com>: Internal change. PiperOrigin-RevId: 361215882 -- 583fe6c94c1c2ef757ef6e78292a15fbe4030e35 by Evan Brown <ezb@google.com>: Increase the minimum number of slots per node from 3 to 4. We also rename kNodeValues (and related names) to kNodeSlots to make it clear that they are about the number of slots per node rather than the number of values per node - kMinNodeValues keeps the same name because it's actually about the number of values rather than the number of slots. Motivation: I think the expected number of values per node, assuming random insertion order, is the average of the maximum and minimum numbers of values per node (kNodeSlots and kMinNodeValues). For large and/or even kNodeSlots, this is ~75% of kNodeSlots, but for kNodeSlots=3, this is ~67% of kNodeSlots. kMinNodeValues (which corresponds to worst-case occupancy) is ~33% of kNodeSlots, when kNodeSlots=3, compared to 50% for even kNodeSlots. This results in higher memory overhead per value, and since this case (kNodeSlots=3) is used when values are large, it seems worth fixing.

I found myself implementing a similar option in our tensorstore project to fuzz test a storage layer and figured that it would be more useful as a common tool with defaults that take the non-random path. This is similar to the FuzzedDataProvider mechanism which generates random values from a fuzz string, and is used to generate fuzz test inputs, and internally it uses FuzzedDataProvider. The basic technique used here is to construct mocking lambdas for all of the absl mock distribution configurations, and forwarding the parameters to fuzzing-specific implementations that call into FuzzedDataProvider. The default paths for the distributions are either the bounds or a median value.
