gix-commitgraph v0.40.0

Bug Fixes

• Keep rust workspace tests inside disposable repositories and isolated environments

  Direct Git launches inherited repository selectors and user configuration even
  when tests supplied a fixture working directory. Tests of default-environment
  APIs and local Git transports also shared the runner's environment. A few
  journey tests wrote beneath source directories or used the source checkout as
  the repository under test.

  Use the shared gix-testtools Git command builder for subprocess setup, isolated
  repository options for fixtures, and isolated child processes where the real
  environment-reading API must be exercised. Scope CWD changes, copy the fixture
  used by an object-write test, and run shell journeys through jtt run. Keep
  journey worktrees and example output within their disposable sandboxes and
  replace the attributes checkout test with a representative fixture repository.
  Prompt examples also run in isolated children and must build successfully; the
  old tests could ignore build failures and execute stale cached binaries.

  The affected Rust crate suites, internal test-tool build, and max-pure journey
  suite pass from a source copy without Git metadata. Signing and Git-daemon
  checks use only disposable keys, repositories, and local sockets.

• preserve I/O errors for missing graph paths

  An absent .git/objects/info directory made Graph::at() return an
  error without its filesystem cause. The optional-cache fallback in
  Repository::commit_graph_if_enabled() could not recognize NotFound,
  so operations such as merge_base(HEAD, HEAD) failed despite having all
  required commit objects.

  Inspect the path with one fallible metadata read and preserve its I/O
  error in the chain. Missing paths now reach the existing fallback, while
  other metadata failures remain distinguishable. Cover the error source
  and merge-base behavior with an empty and then absent objects/info.
  Both regression tests failed before the fix.

  Git reference: commit-graph.c at 1630431f326e15fcde608827b5ff38422528eb59
  uses open_commit_graph(), load_commit_graph_one(), and
  prepare_commit_graph() to fall back when no graph can be opened.
  With Git 2.50.1 (Apple Git-155), git -c core.commitGraph=true merge-base
  returns the expected commits for HEAD HEAD and HEAD HEAD^ with either
  an empty or an absent objects/info directory.

Changed (BREAKING)

• raise MSRV to Rust 1.88

  The newly published dua-core 3.3 release used by linked-worktree removal
  requires Rust 1.88, so raise every workspace crate and the advertised badge
  together.

  Keep the MSRV checks buildable by selecting the latest sysinfo and rusqlite
  release lines that support Rust 1.88.
