Summary

av adopt now exits cleanly on SIGINT (CTRL+C). Threads context.Context through the adopt path, switches git subprocess invocations to exec.CommandContext, and adds a shared signal.NotifyContext install at the Cobra entry.

Why this matters

From #692:

Only way to stop it appears to be to get the process ID and run kill -9 on it.

Other av commands (av sync) honor SIGINT correctly, so the fix mirrors that pattern.

Changes

• cmd/av/main.go: install signal.NotifyContext(ctx, os.Interrupt, syscall.SIGTERM) once at the Cobra root
• cmd/av/adopt.go: propagate the context into the adopt action
• internal/actions/adopt_branches.go, find_adoptable_local_branches.go, get_remote_stacked_pr.go, git_fetch.go: honor ctx.Done() in branch-walk loops
• internal/treedetector/detector.go, internal/utils/uiutils/tea.go: thread context through
• e2e_tests/adopt_test.go: new test spawning av adopt, sending SIGINT, asserting bounded exit time

Partial-state cleanup is correct: no half-adopted branches left in inconsistent state on cancellation.

Fixes #692

Summary by CodeRabbit

• Bug Fixes
  • Local and remote adoption, branch discovery, and related operations now respond to cancellation instead of continuing in the background.
  • The CLI exits promptly when interrupted with Ctrl+C or a termination signal, and skips the version check if cancellation occurs.
  • Remote adoption now uses the active command context when switching to the adopted branch.

Code Review

This pull request implements context propagation and signal handling across the av command suite, enabling graceful termination on SIGINT and SIGTERM. Key changes include the introduction of RunBubbleTeaWithContext, context-aware Git operations, and a new E2E test verifying interrupt behavior. Review feedback identifies a potential data race in GetRemoteStackedPRModel and suggests refactoring the context storage in view models from provider functions to direct struct fields for better idiomatic Go compliance.

[mvanhorn]

Rebased onto master (master picked up the testscript e2e migration in #695) and pushed eaee61d to address the HIGH-priority data race.

State mutations on GetRemoteStackedPRModel (m.failed, m.prs, m.done) are now routed through Update() via two new message types (remoteStackedPRFailedMsg, remoteStackedPRDoneMsg). The Init() goroutine collects PRs into a local slice and only emits messages; all field writes happen on the Bubble Tea main thread, matching the framework contract. Build, go test ./internal/actions/..., and golangci-lint all clean.

The e2e_tests/adopt_test.go TestAdopt_ExitsOnSIGINT addition was dropped during rebase because master migrated to the testscript framework. I'll re-author it as a .txtar in a follow-up if you want explicit e2e SIGINT coverage; happy to fold that in here too if you'd prefer.

Not tackling the two medium suggestions (storing context.Context directly in adopt_branches.go) in this push so the data race fix lands clean. Will follow up.

[mvanhorn]

Follow-up on the two medium gemini items.

SIGINT e2e coverage: pushed ba7620b adding TestAdoptExitsOnSIGINT in e2e_tests/sigint_test.go. It re-uses the merge-base sleep trick the original test had: spawn av adopt --dry-run with PATH-injected fake git that sleeps on merge-base, wait for the marker confirming the sleep started, send os.Interrupt, and assert av returns within 5s. Locks in the SIGINT path through signal.NotifyContext -> RunBubbleTeaWithContext -> the per-model ctx checks. Test passes in ~0.7s. The file deliberately sits outside the testscript harness - testscript v1.10.0 in go.mod has no public API for sending an arbitrary signal to a specific named background process (it only sends os.Interrupt to every backgrounded command at end-of-test via waitBackground). A header comment in the file documents the conditions under which this can migrate into testdata/script as a .txtar.

context.Context direct storage on AdoptBranchesModel / GetRemoteStackedPRModel: tried the suggested refactor, both models then trip the containedctx golangci-lint rule that the repo already enforces. Reverted - keeping the func() context.Context closure indirection consistent with the rest of the codebase. Happy to revisit if the lint rule changes.

[mvanhorn]

Merged master (0e4190b). In cmd/av/main.go I kept master's cachedRepo.Close() defer and the return-based exit, with the signal.NotifyContext passed to ExecuteContext. In get_remote_stacked_pr.go I took master's charm.land v2 imports and kept this PR's done/failed messages, so master's uiutils.SimpleCommandMsg isn't needed there. go test ./... passes, including TestAdoptExitsOnSIGINT.

Walkthrough

The CLI now passes a signal-cancelable context through the adoption flow. Adoption actions use that context for branch detection, Git operations, and remote PR retrieval. An end-to-end test checks that av adopt --dry-run exits after receiving SIGINT.

Full details: Linked Issues check

Explanation

Issue #692 requires that CTRL+C stop av adopt. At the reviewed head, cmd/av/main.go run() creates ctx, stop := signal.NotifyContext(context.Background(), os.Interrupt, syscall.SIGTERM) and calls rootCmd.ExecuteContext(ctx), so the adopt command receives a context that is canceled on SIGINT. checkCliVersion() runs only when ctx.Err() == nil. e2e_tests/sigint_test.go (TestAdoptExitsOnSIGINT) runs av adopt --dry-run with a fake git that blocks at merge-base (exec sleep 30). After the marker file appears, the test sends os.Interrupt to the av process only and fails if the process does not exit within 5 seconds. The previous review traced context propagation through the adopt action models, Git subprocesses, and branch-walk loops at an earlier head. Those adopt-action files were not re-read in this review because the incremental and whole-PR diffs were unavailable. The PR description names e2e_tests/adopt_test.go, but the test at head is in e2e_tests/sigint_test.go. This is a documentation mismatch, not a missing requirement. Test execution was not performed in this review; the pass result relies on the code and test content read at head.

Full details: Out of Scope Changes check

Explanation

The changes read at head stay within issue #692. cmd/av/main.go installs the signal context, passes it to ExecuteContext, and skips the CLI version check after cancellation. This supports clean interrupt handling. The deferred cachedRepo.Close() and return-based exit support clean shutdown on the same path. e2e_tests/sigint_test.go verifies the requested behavior. The previous review found that the context changes in the adopt action models, git_fetch.go, treedetector/detector.go, and uiutils/tea.go are cancellation-related. The get_remote_stacked_pr.go restructuring moves state writes into Bubble Tea Update() and removes goroutine mutations. The PR comments state this fixes a data race in the same cancellable flow. The charm.land v2 import change came from merging master. Its diff could not be read, so it is not independently verified as in scope. It does not affect the issue #692 requirement. No unrelated functional change is demonstrated.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 12 functions across 9 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

- Line 144: Update the `remoteStackedPRDoneMsg` creation to carry only
`collected`, and invoke `m.onDone(msg.prs)` in the done-message branch of
`Update` so the callback runs within Bubble Tea’s update loop.

Review comments at @internal/utils/uiutils/tea.go:
- Around line 65-73: Update the Bubble Tea runner around `tea.NewProgram` and
`p.Run()` to detect when stdout is not a terminal, disable the interactive
renderer, and print `finalModel.View()` so redirected output remains complete
without terminal control output. Preserve the existing exit-error handling.
- Around line 59-62: Update the terminal check in the code that configures
`tea.ProgramOption` so `tea.WithInput(nil)` is selected based on stdin being
non-interactive, independently of stdout. Preserve keyboard input when stdin is
a TTY and stdout is redirected.
