* Migrate most RAW_LOGs and RAW_CHECKs in tests to regular LOG and CHECK.Gravatar Andy Getzendanner2023-05-23
| | | | | | | | | | | The non-RAW_ versions provide better output but weren't available when most of these tests were written. There are just a couple spots where RAW_ is actually needed, e.g. signal handlers and malloc hooks. Also fix a couple warnings in layout_test.cc newly surfaced because the optimizer understands CHECK_XX differently than INTERNAL_CHECK.

If we add support for non-power-of-two-minus-one capacities, this is the correct thing to assert. For example, consider: Group::kWidth = 8, capacity_ = 8, ctrl_ = {kEmpty, 1, 2, 3, 4, 5, 6, 7, kSentinel, kEmpty, 1, 2, 3, 4, 5, 6}. In this case, if we do an unsuccessful lookup with H2 mapping to slot 1, then the first Group will contain {1, 2, 3, 4, 5, 6, 7, kSentinel} so we need to continue to the second Group (at which point seq.index() == 8 == capacity_) to find a kEmpty. Note: this is a no-op change for now since we never have `capacity % Group::kWidth == 0`.

When alignof(slot_type)>1, this wouldn't cause a problem because the extra byte is padding. Also change loop bounds to not rely on the fact that capacity_+1 is a multiple of Group::kWidth. PiperOrigin-RevId: 379311830 -- 1a3ba500fb2c33205854eb9258cd6e0fb1061bca by Martijn Vels <mvels@google.com>: Change Ring, EXTERNAL and FLAT tag values to be consecutive values The purpose of this change is to have FLAT = EXTERNAL + 1. Especially in the ring and btree alternative code, there is a common check if a node is a 'plain' edge (EXTERNAL or FLAT), or 'something else'. This change can make that check a single branch, i.e., instead of 'tag == EXTERNAL || tag >= FLAT', we can simply check for 'tag >= EXTERNAL'. Likewise we have some cases where we check for RING, EXTERNAL or FLAT, so we align RING + 1 with EXTERNAL. PiperOrigin-RevId: 379291576 -- 0c78e65ca4d85244b106c3f8e24cf268e09e72a3 by Benjamin Barenblat <bbaren@google.com>: Round a double multiplication before casting it to integer The code static_cast<int>(x * y) (for double x and y) performs a double multiplication into a temporary that, by standard, may have excess precision. The subsequent cast to int discards the excess precision. However, the cast may examine the excess precision during conversion, producing surprising results like static_cast<int>(1.7 * 10) == 16 on certain systems. Correct this case by explicitly rounding 1.7 * 10 before casting it.

In Abseil random, mocking was split across two different classes, MockingBitGenBase and MockingBitGen. This split existed because Google Mock is a test-only library that we don't link into production, so MockingBitGenBase provided a low-overhead scaffold used to lookup mocks when in test code, but which is unused in production code. That has been replaced by type-erasure which looks for a method named CallImpl with the correct signature. Weaken the coupling between MockingBitGen, DistributionCaller, and MockOverloadSet. Rename CallImpl to InvokeMock() Previously, the implementation of DistributionCaller was also split across different files using explicit instantiation of the DistributionCaller struct and some details in the Mocking classes. Now Distribution caller uses the presence of the InvokeMock() method to choose whether to use the mockable call path or the default call path.

Stealing string data is faster, but it creates a long chunk, which leads to a higher more memory usage if its subcords are created and outlive the whole Cord. These functions revert to copying the data if any of the following conditions holds: - string size is at most kMaxBytesToCopy (511), to avoid the overhead of an external chunk for short strings; - less than half of string capacity is used, to avoid pinning to much unused memory.
