2024-01-11Add support for Bzlmod for the next releaseDerek Mauro
https://bazel.build/external/overview#bzlmod Bzlmod will be the default in a future Bazel release. By default it requires projects to be registered with the Bazel Central Registry (https://registry.bazel.build/) and thus uses regular releases by default. Users that want to "live-at-head" can still do this through with overrides (https://bazel.build/external/module#overrides). This change updates Abseil dependencies to use released versions. CI uses Bzlmod except in the case of linux_gcc-floor, which will keep testing the old WORKSPACE-based dependency system.

2024-01-05Extend BM_StrAppendInt to use log-uniform random numbers instead of constantsAbseil Team
This follows Benford's law, which is likely also a much more accurate representation of real data than a constant. We also add benchmarks for different integer types. PiperOrigin-RevId: 596039508 Change-Id: I4862c7cfdbf5face18ae31cf0bd2fd54e47684b7
2024-01-04Optimize integer-to-string conversionsAbseil Team
The updated code is designed to: - Be branch-predictor-friendly - Be cache-friendly - Minimize the lengths of critical paths - Minimize slow operations (particularly multiplications) - Minimize binary/codegen bloat The most notable performance trick here is perhaps the precomputation & caching of the number of digits, so that we can reuse/exploit it when writing the output. This precomputation of the exact length enables 2 further performance benefits: - It makes `StrCat` and `StrAppend` zero-copy when only integers are passed, by avoiding intermediate `AlphaNum` entirely in those cases. If needed in the future, we can probably also make many other mixtures of non-integer types zero-copy as well. - It avoids over-reservation of the string buffer, allowing for more strings to fit inside SSO, which will likely have further performance benefits. There is also a side benefit of preventing `FastIntToBuffer` from writing beyond the end of the buffer, which has caused buffer overflows in the past. The new code continues to use & extend some of the existing core tricks (such as the division-by-100 trick), as those are already efficient.

2024-01-03Avoid a empty library build failure on Apple platformsDerek Mauro
https://github.com/abseil/abseil-cpp/issues/1465 reports that some CMake builds on Apply platforms issue ``` warning: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: archive library: libabsl_bad_any_cast_impl.a the table of contents is empty (no object file members in the library define global symbols) ``` Our CMake build handles this problem for header-only libraries by not building a library at all. For some libraries, for example our polyfills, the library is only conditionally empty. In these libraries, I added a single char variable on Apple platforms as a workaround. I have been able to reproduce the warnings reported in https://github.com/abseil/abseil-cpp/issues/1465, but they don't fail the build for me. I don't see them any more after this change.

2023-12-20AddressIsReadable: improve commentsFangrui Song
Linux kernel's rt_sigprocmask correctly handles an unaligned user address[1]. The original issue was for qemu-user, which seems long irrelevant. Tested locally on an AArch64 CPU and qemu-aarch64-static. The alignment operation actually serves another purpose: when addr resides in the last 7 bytes of a page (unaligned), check only the current page and not the next. Update the comment.
