sccache 0.18.0

Summary

sccache 0.18.0 is a broad correctness and coverage release: a lot of compiler flags that used to
force a cache miss are now understood, several cache-key and multi-level storage bugs are fixed,
and the Azure backend gained passwordless authentication.

Highlights:

• Cache-key correctness: the assembler gcc/clang would actually invoke is now part of the cache
  key, so two toolchains with different binutils can no longer hand each other the wrong object
  file (#​2843). SCCACHE_BASEDIRS now also strips base directories from the compiler arguments,
  so flags like -ffile-prefix-map=/home/user/project=. stop tying an entry to one checkout
  (#​2840).
• MSVC/clang flag coverage: support for /openmp:llvm, the /fsanitize*, /fsanitize-coverage*
  and /fno-sanitize* families, /feature, arm64EC and fastfail, /d20bforceinline, and a large
  batch of other flags (#​2807, #​2830, #​2831, #​2832), plus more clang CLI options (#​2834). gcc now
  marks flags as TooHard when they would require caching something else (#​2833).
• CUDA: nvcc dryrun parsing works with CUDA 13.3 (#​2722), escaped quotes in Windows dryrun
  lines are protected before backslash flattening (#​2811), and the
  --diag-error/--diag-suppress/--diag-warn family is accepted (#​2816).
• Multi-level cache: a chain with any writable level is writable again — a single read-only
  level no longer makes the whole storage read-only (#​2778) — and reads are no longer issued twice
  (#​2835).
• Azure: Microsoft Entra ID (passwordless) authentication for the Azure Blob backend, for
  storage accounts that disable shared-key access (#​2802).
• Distributed compilation: rlibs are no longer trimmed from crates that also emit a cdylib,
  which made those jobs fail on the build server (#​2839).
• Process handling: the jobserver is no longer handed to children that can't use it, which
  restores the posix_spawn fast path for child spawns (#​2827), and daemonization now uses an
  allow-list for inherited file descriptors, fixing make deadlocks caused by leaked jobserver FDs
  (#​2841).
• MSRV is now 1.91.0 (#​2793).
