build(deps-dev): bump ruff from 0.15.22 to 0.16.4 - #1386
Merged
Conversation
Ruff 0.16 expanded its default rule set from 59 to 413 rules, which would silently enforce dozens of new lint categories across the codebase. Pin the previous default explicitly (E4, E7, E9, F) so the version bump doesn't also change what's enforced; adopting the wider rule set is left as a deliberate follow-up.

Ruff 0.16 expanded its default rule set from 59 to 413 rules, surfacing 33
findings in dfetch/. Rather than freezing the previous rule selection, fix
each one at the root:
- Prefer TypeError over RuntimeError for isinstance-based type checks (TRY004)
- Drop unnecessary reversed(sorted(...)) in favor of sorted(..., reverse=True) (C413)
- Mark DLogger._printed_projects as ClassVar since it's genuinely shared
class-level state (RUF012)
- Build the schema-validation error message with an f-string (FLY002)
- Iterate TypedDict.__annotations__ directly instead of via .keys() (SIM118)
- Replace @lru_cache on GitSubProject.get_default_branch (which pins `self`
for the class's lifetime) with a simple per-instance cache (B019)
- Make last-fetch timestamps timezone-aware (UTC) (DTZ001, DTZ005)
- Use Path.cwd() instead of Path(".").resolve() (FURB177)
- Combine a nested if into a single condition (SIM102)
- Use contextlib.AbstractContextManager instead of deprecated
typing.ContextManager (UP035)
- Build BrowserConfig lazily instead of as a mutable-looking argument
default (B008)
- Re-raise the original exception explicitly in the shutil.rmtree onerror
callback instead of relying on a bare `raise` outside its own except
block (PLE0704)
- Narrow the tree-browse fetch's exception handling to the VCS command
errors it can actually raise instead of a blanket Exception (BLE001)
Also add known-third-party = ["_hashlib"] to ruff's isort settings so its
import sort agrees with the isort tool (which doesn't classify that private
stdlib extension module as standard library) instead of the two fighting
over import grouping in dfetch/util/util.py.

- Line 313: Reformat the schema validation error construction in the relevant
manifest validation code so the message remains identical while the expression
complies with Black and PEP8 line-length rules. Preserve the existing
err.context_mark.get_snippet() and err.problem details.
In `@dfetch/resources/__init__.py`:
- Line 7: Update the self-import in the resources package initializer to remove
the inline Pylint suppression, replacing it with a package or module-name lookup
that preserves the compiled-resource branch behavior.
In `@dfetch/vcs/git.py`:
- Line 257: Update browse_tree so the entire temporary-directory context-manager
body, including fetch_for_tree_browse, get_default_branch, and yield logic,
executes inside the outer try/finally; ensure tmpdir cleanup runs for all
exception types, not only SubprocessCommandError and RuntimeError.

- Wrap the schema validation error message onto multiple string literals to keep the line under the conventional length - Drop the dfetch.resources self-import and its inline pylint suppression; pass __name__ to importlib.resources.files() instead, which resolves to the same package - Move browse_tree's fetch/yield logic inside the outer try/finally so the temporary clone directory is always cleaned up, even if an exception other than SubprocessCommandError/RuntimeError is raised
