Summary

Closes #79

  • discover_tracked_lockfiles previously hid a non-git workspace behind a warning and a silent empty tuple. It now raises a typed NotAGitRepositoryError (subclass of LockfileDiscoveryError) for non-git workspaces; other git failures keep raising LockfileDiscoveryError.
  • The skip policy moves to the caller: publish pre-flight catches NotAGitRepositoryError, warns, and continues — preserving operator behaviour while making the condition explicit at the API.
  • I/O is confined to ports: git access through the injected runner, filesystem access through the injected manifest_exists adapter; the function performs no direct I/O of its own (documented in the docstring).

Testing

  • New tests/integration/test_lockfile_discovery.py exercises discovery against real git repositories in temporary directories through the real subprocess runner, without stubbing internals: tracked vs untracked lockfiles, target/ exclusion, manifest adjacency, and the non-git typed error.
  • The silent-skip unit test is replaced with a typed-exception assertion; a caller-policy test pins the pre-flight skip behaviour.
  • make check-fmt, make lint, make typecheck, and make test (565 passed) all green after rebasing onto current main.
  • coderabbit review --agent: 0 findings.

Summary by Sourcery

Surface non-git workspaces as typed errors during Cargo.lock discovery and delegate skip policy to the publish pre-flight caller.

New Features:

  • Introduce a NotAGitRepositoryError subclass of LockfileDiscoveryError to represent lockfile discovery in non-git workspaces.

Bug Fixes:

  • Ensure non-git workspaces no longer appear as a silent success with an empty lockfile set during discovery.

Enhancements:

  • Refine lockfile discovery error handling to raise explicit exceptions on git failures rather than returning sentinel values.
  • Confine I/O in lockfile discovery to injected git runner and manifest-existence adapters to improve testability and separation of concerns.

Tests:

  • Add integration tests for lockfile discovery against real git repositories, covering tracked vs untracked lockfiles, target directory exclusion, manifest adjacency, and non-git error handling.
  • Update unit tests to assert typed exceptions for non-git workspaces and to verify the publish pre-flight skip policy for non-git repositories.

Summary

  • Raise typed exceptions during lockfile discovery:
    • Use NotAGitRepositoryError for non-Git workspaces.
    • Use LockfileDiscoveryError for other Git failures.
  • Route Git and filesystem access through injected adapters.
  • Move Cargo lockfile freshness checks to publish_lockfile_preflight.py.
  • Skip publish validation with a warning outside Git repositories.
  • Preserve configured manifests during bump operations outside Git repositories.
  • Report stale lockfiles with repair commands.
  • Record lockfile discovery failures with reason-specific metrics.
  • Enforce a C locale for subprocess environments.
  • Add integration tests with real temporary Git repositories.
  • Update unit tests and developer and user documentation.
  • Align the implementation with docs/lading-design.md.

Walkthrough

Lockfile discovery now raises typed exceptions for non-Git workspaces and Git command failures. Publish freshness validation uses a dedicated repository port and policy module. Subprocesses now enforce the C locale.

Poem

Typed errors mark the Git trail,
Fresh locks pass the gate.
Stale locks print repair commands,
Ports keep the layers straight.
C-locale commands speak clearly.

Merge Risk: 🟡 Moderate · up to 38a03

The change exposes non-Git workspaces through a typed error while preserving publish behavior, but a test helper passes the wrong argument type to that error and can fail static type checking; merge should wait for this correction.

Reviewer's Guide

Refactors lockfile discovery to surface non-git workspaces via a typed exception instead of a silent skip, moves the skip policy to the publish preflight caller, and adds integration and unit tests that exercise discovery against real git repositories and assert the new error-handling behavior.

File-Level Changes

Change Details Files
Surface non-git workspaces as a typed discovery error instead of silently returning an empty result.
  • Introduce NotAGitRepositoryError as a LockfileDiscoveryError subclass with documentation on caller-owned skip policy.
  • Replace _handle_git_ls_files_failure with _raise_git_ls_files_failure that always raises typed errors for non-zero git ls-files exit codes.
  • Update discover_tracked_lockfiles to call the new helper on git failures, document raised exceptions in the docstring, and clarify that all I/O goes through injected runner and manifest_exists ports.
lading/commands/lockfile.py
Move the non-git workspace skip policy into publish preflight validation logic.
  • Wrap discover_tracked_lockfiles in _validate_lockfile_freshness with a try/except for NotAGitRepositoryError.
  • On NotAGitRepositoryError, log a warning that freshness validation is being skipped for a non-git workspace and return early without running cargo commands.
lading/commands/publish_preflight.py
Align unit tests with the new typed error behavior and caller-owned skip policy.
  • Change the discover_tracked_lockfiles non-git directory unit test to expect NotAGitRepositoryError instead of an empty tuple.
  • Add a preflight unit test that injects a discovery function raising NotAGitRepositoryError and asserts that validation logs a warning and performs no cargo runner calls.
tests/unit/test_lockfile.py
tests/unit/publish/test_preflight_lockfile_validation.py
Add integration tests that exercise lockfile discovery against real git repositories via the subprocess runner.
  • Create helper functions to initialize temporary git repos, add crates with/without manifests, and run git commands with deterministic identity.
  • Add tests that verify discovery returns only tracked lockfiles with adjacent manifests, ignores untracked and target/ lockfiles, and raises NotAGitRepositoryError for non-git directories when invoked with subprocess_runner.
tests/integration/test_lockfile_discovery.py

Assessment against linked issues

Issue Objective Addressed Explanation
#79 Refactor discover_tracked_lockfiles so all filesystem operations (lockfile enumeration, manifest existence checks) are routed through injected ports (runner/manifest_exists) and the function performs no direct Path I/O.
#79 Make lockfile discovery failures explicit in the public API by surfacing errors (e.g., via typed exceptions) instead of logging warnings and returning empty tuples silently.
#79 Replace the previous mock-based tests for lockfile discovery with real integration tests that exercise discovery (and related behaviour) against temporary directories and real git/subprocess interactions.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Classify non-Git workspaces without parsing localised Git diagnostics.

Do not use the English text "not a git repository" as the classifier. Git
can localise stderr. In that case, this path raises LockfileDiscoveryError
instead of NotAGitRepositoryError, so publish pre-flight aborts rather than
logging the required skip warning.

Force a deterministic locale through the injected command environment, while
preserving the bound pre-flight environment. Add a unit test with non-English
stderr that still expects NotAGitRepositoryError.

Add diagnostic messages to the assertions.

Add a failure message to each assertion. Identify the expected tracked,
untracked, and target filtering behaviour in the messages.

As per coding guidelines and path instructions, “Use assert …, "message" over
bare asserts”.

Sources: Coding guidelines, Path instructions

discover_tracked_lockfiles hid a non-git workspace behind a warning
and a silent empty tuple, so callers could not distinguish "no
tracked lockfiles" from "discovery never ran". Filesystem access was
also mixed into the function rather than confined to a port.

Raise a typed NotAGitRepositoryError (subclass of
LockfileDiscoveryError) for non-git workspaces and keep
LockfileDiscoveryError for other git failures. The skip policy moves
to the caller: publish pre-flight catches NotAGitRepositoryError,
warns, and continues, preserving existing operator behaviour while
making the condition explicit at the API.

Filesystem access is now documented as confined to the injected
manifest_exists port and git access to the injected runner; the
function performs no direct I/O of its own.

Replace the silent-skip unit test with a typed-exception assertion,
add a caller-policy test for the pre-flight skip, and add integration
tests that exercise discovery against real git repositories in
temporary directories through the real subprocess runner (tracked
versus untracked lockfiles, target/ exclusion, manifest adjacency,
and the non-git error).

Extract the lockfile freshness policy (_validate_lockfile_freshness,
_collect_stale_lockfiles, _build_stale_lockfile_message) into the
colocated module publish_lockfile_preflight. Adding the skip branch
took publish_preflight past the repository's 400-line file limit, and
the freshness policy is a coherent unit: it depends only on the
LockfileInspectionRepository port, while publish_preflight retains the
cargo and git command orchestration and stays the composition root
that binds the adapter.

Apply the same caller-owned skip policy on the bump side. Since #160,
bump discovers tracked lockfiles through
bump_lockfile_manifests.merge_discovered_manifests, whose documented
contract is that a non-git workspace returns the configured manifests
unchanged. That relied on discovery's silent empty tuple, so the typed
error would otherwise abort `lading bump` outside git control; the
merge helper now catches NotAGitRepositoryError, warns, and returns the
configured tuple.

Address review feedback. NotAGitRepositoryError now carries the failing
workspace_root as a structured attribute, matching CommandSpawnError and
WorkspaceDependencyCycleError, so callers need not parse the message. Add
a bounded lockfile.discovery.failed counter (reason=not_git|git_error) and
log the unexpected-failure branch at the failure boundary; success volume
stays on lockfile.discovered so quiet runs stay quiet.

Discovery classifies a non-git workspace by matching git's English text,
which a localized machine would translate and silently misclassify. Pin
the C locale in subprocess_runner, the single adapter that spawns
processes, via the new lading.utils.process.c_locale_env helper. Test
doubles bypass it, so no double needs widening, and cargo's output is
covered too. Classifying on the exit status instead is not possible:
git ls-files exits 128 for every fatal condition.

Move the LockfileInspectionRepository port and its adapter into
lockfile_repository, with their tests, keeping lockfile.py inside the
400-line limit and separating the hexagonal boundary from the domain
operations.

Restore the inline-code exclusion in typos.local.toml. Regenerating
typos.toml from the shared authority had dropped it, so the spelling gate
flagged identifiers such as `normalise_workspace_root` that must keep
their source spelling.

In a workspace that is not a Git repository, tracked-lockfile discovery cannot
run, so `lading publish` logs a warning and skips this freshness check rather
than failing. `lading bump` is not affected in the same way: it still
regenerates the manifests listed in the [`[bump]`](#bump) `lockfile_manifests`
setting.

Describe the regenerated artefact correctly.

Replace “regenerates the manifests” with “regenerates the lockfiles adjacent to
the configured manifests”. The current text incorrectly states that non-Git
recovery regenerates Cargo.toml files.

Construct the exception message before calling super().

Assign the formatted message to message, then pass message to the exception
constructor. This keeps exception construction consistent with the required
exception design rule.

Pass workspace_root to NotAGitRepositoryError.

Replace the formatted str message with workspace_root. The constructor
requires Path, so Line 221 fails Pyright type checking. The current double
also fails to model the structured exception context used by production code.
