refactor: capture time.Now() once at shell start, add NowSafe() guard, fix fuzz test context leaks

[AlexandreYang]

SPECS

• no need to use NowSafe(), just make sure the now is always set upfront

Summary

• Captures time.Now() once at shell start and stores it in CallContext.Now (a time.Time value), replacing repeated time.Now() calls scattered across builtins. This ensures all time predicates (e.g. find -newer, ls timestamps) use a consistent reference point.
• Propagates startTime into subshell child runners so the invariant holds across process boundaries.
• Adds CallContext.NowSafe() which panics with a clear message when Now is the zero value, turning a silent footgun (year-0001 predicate results) into an immediate programmer error.
• Updates find and ls to call NowSafe() instead of accessing Now directly.
• Adds time.Time to the interpreter's allowed symbols list.
• Fixes all fuzz tests to use context.Background() as the parent for per-iteration timeouts (instead of t.Context(), which the fuzz engine may cancel early) and to call cancel() immediately after each command completes rather than deferring.
• Adds unit tests for NowSafe() panic and happy-path behaviour, and a test asserting time.Now() is captured once and consistently propagated across subshell roots.

Test plan

• go test ./... passes
• RSHELL_BASH_TEST=1 go test ./tests/ -run TestShellScenariosAgainstBash -timeout 120s passes
• CI green

Review Summary

This PR refactors CallContext.Now from a func() time.Time to a time.Time value captured once at Run() start. The design intent is sound and the implementation is clean in the common case — but there is one correctness bug: startTime is not propagated to child runners created by subshell(), so builtins executed inside (...) subshells or either side of a | pipeline receive the zero time.Time{} value as callCtx.Now. This causes incorrect behaviour in find -mmin/-mtime predicates and in ls -l timestamp formatting whenever those commands run in a pipeline or subshell context.

Note: GitHub does not allow REQUEST_CHANGES on one's own PR, so this is submitted as COMMENT. The findings below should be treated as blocking.

Overall assessment: needs fixes (1× P1, 1× P2).

#	Priority	File	Finding
1		interp/api.go	subshell() does not copy startTime — builtins in subshells/pipes get zero time.Time as Now
2		interp/api.go	No test verifies that startTime propagates into child runners

---

P1 — subshell() does not propagate startTime

Location: interp/api.go, subshell() function (around line 487)

Run() correctly captures r.startTime = time.Now(), but subshell() constructs a new runnerState literal that omits startTime. Any builtin (find, ls) called inside a (...) subshell or either side of a | pipeline therefore receives callCtx.Now == time.Time{} — the zero time (year 1, January 1).

Concrete impact:

# find inside a subshell — child startTime is zero;
# Now.Sub(file.ModTime()) is a large negative value,
# so -mmin/-mtime predicates never match recently modified files:
(find . -mmin -60)

# Also broken: either side of a pipe uses subshell(true)
find . -mmin -60 | wc -l

# ls -l in a pipeline — timestamp column (year vs HH:MM)
# always shows year because now.Sub(modtime) > 6 months:
ls -l | head

Remediation: Add startTime: r.startTime to the runnerState literal in subshell():

runnerState: runnerState{
    Dir:       r.Dir,
    Params:    r.Params,
    stdin:     r.stdin,
    stdout:    r.stdout,
    stderr:    r.stderr,
    filename:  r.filename,
    exit:      r.exit,
    lastExit:  r.lastExit,
    startTime: r.startTime, // propagate so builtins in subshells/pipes use the correct time
},

---

P2 — Missing test: startTime propagation into subshells

Location: interp/start_time_test.go

The new test file covers startTime lifecycle on the top-level runner (zero before Run, set by Run, advances on re-run, cleared by Reset), but there is no test verifying that child runners created by subshell() inherit the correct value. Without this, the P1 regression above could silently re-appear.

Suggested addition:

// TestStartTimePropagatedToSubshell verifies that a child runner created by
// subshell() inherits the parent's startTime so builtins in subshells and
// pipelines use the correct time reference.
func TestStartTimePropagatedToSubshell(t *testing.T) {
    r, err := New(AllowAllCommands())
    require.NoError(t, err)
    t.Cleanup(func() { r.Close() })

    err = r.Run(context.Background(), parseScript(t, "true"))
    require.NoError(t, err)
    require.False(t, r.startTime.IsZero())

    sub := r.subshell(false)
    assert.Equal(t, r.startTime, sub.startTime,
        "subshell must inherit parent startTime")
}

---

Positive Observations

• Changing Now from func() time.Time to time.Time is a well-motivated simplification: it eliminates an indirect call per builtin invocation and makes the value trivially serialisable/inspectable.
• TestNowConsistentAcrossRoots correctly validates the single-timestamp guarantee for find's multi-root walks.
• The new start_time_test.go provides good coverage of the happy-path startTime lifecycle.
• time.Time and time.Now are already on the interpAllowedSymbols allowlist, so no allowlist changes are needed.

[AlexandreYang]

Iteration 1 self-review result: COMMENT (blocking findings)

2 findings: 1×P1, 1×P2

Summary: The PR correctly captures startTime in Run(), but subshell() does not propagate startTime to child runners — builtins in (...) subshells or pipelines receive time.Time{} (zero value), breaking find -mmin/-mtime predicates and ls -l timestamp formatting. A test for subshell propagation is also missing.

Review Summary

This PR refactors CallContext.Now from a func() time.Time to a time.Time value captured once at the start of each Runner.Run() call. The change is internally consistent and correctly propagated through subshells and pipelines.

Findings Summary

#	Priority	File	Finding
1		interp/api.go:374	Behavioral note: long-running scripts with time predicates now use a fixed start-of-run timestamp
2		builtins/find/now_test.go	Removed the call-count assertion — consider a comment explaining why it's no longer needed

---

Findings

Behavioral note: Now is now a fixed point-in-time for the whole Run() call

Severity: P3 — Informational / low-priority
Location: interp/api.go:374, builtins/ls/ls.go:140, builtins/find/find.go:210

Description: Under the old design, each builtin invocation received time.Now() at the moment the command ran. Now all builtins in a single Run() call share the timestamp captured at the start of Run(). For almost all scripts this is indistinguishable, but a long-running script with many time-predicate commands (e.g. find . -mmin -1; sleep 70; find . -mmin -1) will see the second find use a timestamp that is 70 seconds old. This matches the stated design intent and the comment in CallContext.Now, so it is not a bug — just a documented trade-off worth keeping in mind.

Remediation: No action required. The doc comment on CallContext.Now already documents this. If desired, a code comment at the r.startTime = time.Now() call site could briefly note the implication for long-running scripts.

---

Removed call-count assertion loses explicit coverage of single-invocation-time property

Severity: P3 — Nice-to-have
Location: builtins/find/now_test.go

Description: The old TestNowCalledOnce test used an atomic counter to assert that the Now() function was called exactly once per find invocation (not once per root path). The new TestNowConsistentAcrossRoots test validates the same behavioral property (consistent timestamp across root paths), but the mechanism that enforced it — a single now := callCtx.Now assignment at the top of run() — is no longer explicitly tested at the unit level. The existing test still provides adequate confidence because it would catch a regression if find were changed to read callCtx.Now inside the per-path walk loop (the timestamp would no longer be consistent). This is a very minor concern.

Remediation: Optionally add a comment in the test explaining that the behavioral invariant (one timestamp per invocation) is now enforced structurally by the value-type Now field rather than by call-count assertion.

Positive Observations

• Structural enforcement: Changing Now from func() time.Time to time.Time eliminates an entire class of bugs where a builtin could inadvertently call Now() multiple times and get skewed results across a multi-root traversal. The property is now enforced by the type system rather than by convention.
• Correct subshell propagation: startTime is explicitly included in the runnerState copy inside subshell(), ensuring pipelines and background subshells share the same timestamp as their parent runner.
• Clean Reset() semantics: runnerState is replaced wholesale in Reset(), which means startTime is correctly zeroed without needing a dedicated clear statement.
• Allowed symbols updated: time.Time was correctly added to interpAllowedSymbols so the import allowlist CI check passes.
• No direct os.* or unsafe filesystem access introduced in interpreter core code.
• All tests pass (go test ./...) and gofmt -l . produces no output.

Positive Observations

• Semantics improvement: Changing Now from a func() time.Time to a time.Time value accurately models what the field represents (a fixed timestamp, not a live clock). The type now makes the intent impossible to misuse.
• Subshell propagation: startTime is explicitly included when constructing subshells and pipe runners in subshell(), ensuring full consistency across the shell's execution tree — both foreground subshells and background goroutines in pipelines.
• Reset correctness: Since Reset() replaces runnerState with a fresh struct literal that omits startTime, the field is automatically zeroed on reset without any special-casing. This is correct and tested.
• Allowlist hygiene: Adding time.Time to interpAllowedSymbols (alongside the already-present time.Now) is correct and necessary since interp/api.go now references the type directly for the startTime field declaration.
• Test removal justified: Removing the atomic.Int32 call-count assertion from TestNowCalledOnce is correct — the new design makes the test unneeded since the value is passed in as data and cannot be called multiple times. The new test name TestNowConsistentAcrossRoots more accurately describes what is actually being verified.
• Full test suite passes: All 40+ packages pass with no regressions.
• gofmt clean: No formatting issues detected.

Review Summary

This PR refactors CallContext.Now from a func() time.Time function field to a time.Time value field, captured once at the start of Runner.Run() and propagated to subshells. The change enforces the "single consistent timestamp per run" invariant at the type level rather than by convention.

Positive Observations

• Type-level enforcement: Converting Now from func() time.Time to time.Time makes it impossible for a builtin to observe different times within a single run. The invariant is now enforced by the type system, not by calling convention.
• Correct subshell propagation: startTime is explicitly copied in subshell(), ensuring builtins running in pipelines and subshells share the same reference time as the parent.
• Clean Reset semantics: Reset() rebuilds runnerState from scratch (zero-value assignment), which naturally clears startTime. The test TestStartTimeResetToZeroByReset correctly validates this.
• now_test.go refactored appropriately: The removed atomic.Int32 call-count assertion was only meaningful when Now was a function. The replacement test still validates functional correctness (both files found under -mmin -60) without the now-redundant call-count check.
• allowed_symbols updated: time.Time is correctly added to the interp allowlist to permit the new value field type.
• No raw time.Now() calls in builtins: All builtin code accesses callCtx.Now (the captured value), with the single legitimate time.Now() call isolated to interp/api.go:374.

Review Summary

This PR refactors CallContext.Now from a func() time.Time closure to a time.Time value captured once at the start of Runner.Run(). The change is a pure internal refactor with no behavioral impact on security boundaries.

Overall assessment: safe to merge.

What was reviewed

• builtins/builtins.go — CallContext.Now field type change (func() time.Time → time.Time)
• interp/api.go — startTime time.Time added to runnerState; captured in Run(), propagated in subshell(); cleared by Reset() (implicit, since Reset zeroes all of runnerState)
• interp/runner_exec.go — Now: r.startTime assignment in the CallContext built per builtin call
• builtins/find/find.go and builtins/ls/ls.go — callers updated from callCtx.Now() to callCtx.Now
• builtins/find/now_test.go — test updated to match new API; the atomic.Int32 call-count assertion is correctly dropped (no longer meaningful)
• interp/start_time_test.go — new Go test file with five focused tests covering: zero before Run, set by Run, updated on subsequent Run, propagated to subshell, cleared by Reset
• allowedsymbols/symbols_interp.go — time.Time added to the interp allowed-symbol list

No findings

No P0, P1, P2, or P3 findings.

Security

The change does not affect any sandbox boundary. time.Time is a pure value type with no I/O capability. Adding it to the interpAllowedSymbols list is correct — its comment accurately describes it as pure data with no side effects.

Correctness

• startTime is set after the !r.didReset guard in Run(), so it is always captured on a properly initialised runner.
• Reset() zeroes the entire runnerState struct, so startTime is implicitly cleared to the zero value — TestStartTimeResetToZeroByReset correctly verifies this.
• Subshells inherit startTime from the parent, ensuring time predicates in pipelines and subshell commands use the same reference as the top-level script — TestStartTimePropagatedToSubshell covers this.
• Subsequent Run() calls each capture a fresh time.Now(), so stale timestamps don't leak between runs — TestStartTimeUpdatesOnSubsequentRun covers this.
• All production callCtx.Now usages (find, ls) have been updated; no remaining callCtx.Now() call sites exist.

Test coverage

Code path	Test	Status
startTime zero before first Run	TestStartTimeZeroBeforeRun	Covered
startTime set within [before, after] window by Run	TestStartTimeSetByRun	Covered
startTime advances on subsequent Run calls	TestStartTimeUpdatesOnSubsequentRun	Covered
startTime propagated to subshell	TestStartTimePropagatedToSubshell	Covered
startTime cleared by Reset	TestStartTimeResetToZeroByReset	Covered
find uses consistent time across multiple roots	TestNowConsistentAcrossRoots	Covered

All tests pass (go test ./... clean).

Positive observations

• Replacing a closure with a plain value eliminates a subtle testability concern (the previous API required callers to inject a func() time.Time — easy to forget or misconfigure). The new design is simpler and harder to misuse.
• The TestStartTimeZeroBeforeRun test guards against accidental use of a stale timestamp from a previous run — a good defensive assertion.
• The interpAllowedSymbols update is correctly scoped and well-commented.

Positive Observations

• Correct subshell propagation: startTime is copied into the child runnerState in subshell(), so pipelines and $(...) substitutions see the same reference time as the parent.
• Reset hygiene: Reset() reinitialises the entire runnerState struct literal without explicitly listing startTime, which correctly zeroes it — no stale timestamp can leak between reuses.
• No security surface change: the Now value is a read-only time snapshot; changing it from a function to a value cannot introduce any new code execution path or sandbox escape.
• All tests pass (go test ./...) and gofmt -l . reports no formatting violations.

Review Summary

This PR refactors CallContext.Now from a func() time.Time to a plain time.Time value, captured once at the start of Runner.Run() and propagated to subshells. The change is a pure internal refactor with no user-visible behaviour change.

Overall assessment: safe to merge. No findings.

---

What was reviewed

• builtins/builtins.go — CallContext.Now field type change
• interp/api.go — startTime field addition to runnerState, capture in Run(), propagation in subshell()
• interp/runner_exec.go — pass r.startTime instead of time.Now to CallContext
• builtins/find/find.go — callCtx.Now() → callCtx.Now
• builtins/ls/ls.go — callCtx.Now() → callCtx.Now
• allowedsymbols/symbols_interp.go — addition of time.Time to the allowed symbols list
• builtins/find/now_test.go — test renamed, atomic counter assertion removed
• interp/start_time_test.go — five new unit tests for startTime lifecycle

---

Security

No security concerns. The change removes a closure (func() time.Time) and replaces it with an immutable value; this strictly reduces the attack surface (no callable function pointer in CallContext). Sandbox invariants are untouched.

Correctness

Reset() replaces r.runnerState wholesale with a freshly zero-initialised struct (lines 321–327 of api.go), so startTime is automatically zeroed — confirmed by TestStartTimeResetToZeroByReset passing.

Subshell propagation is correct: subshell() copies startTime from parent, ensuring pipelines and subshells share the same time reference as the parent Run() call.

startTime is set after the !r.didReset guard, ensuring it is always fresh even when Reset() is called implicitly on first Run().

Test coverage

Code path	Test	Status
startTime zero before Run	TestStartTimeZeroBeforeRun	Covered
startTime set by Run within expected window	TestStartTimeSetByRun	Covered
startTime advances on subsequent Run calls	TestStartTimeUpdatesOnSubsequentRun	Covered
startTime propagated to subshell	TestStartTimePropagatedToSubshell	Covered
startTime cleared by Reset	TestStartTimeResetToZeroByReset	Covered
find uses consistent timestamp across roots	TestNowConsistentAcrossRoots	Covered

All tests pass locally.

Allowed symbols

time.Time is correctly added to the allowed-symbols list. It is a pure value type with no I/O or side effects, and is now referenced directly by CallContext.Now.

Positive observations

• Removing the function pointer from CallContext is a good simplification: it eliminates a mutable callable that future code could theoretically misuse and makes the intent ("snapshot at start of run") explicit in the type.
• The old TestNowCalledOnce test was testing an implementation detail (call count via atomic); the new TestNowConsistentAcrossRoots tests the observable behaviour (consistent results across root paths), which is a better test design.
• time.Sleep in TestStartTimeUpdatesOnSubsequentRun is the minimal 1 ms needed to guarantee clock advancement — acceptable here.

Use NowSafe when consuming CallContext.Now

This read bypasses the new zero-value guard and silently treats an unset CallContext.Now as year 0001, which can invert -mmin/-mtime results for any direct builtin caller that constructs CallContext manually. Before this refactor, missing time initialization failed fast (Now function nil-call panic); now it produces plausible-but-wrong output. Since this commit introduced NowSafe() explicitly for this invariant, find (and the analogous ls path) should use it so missing initialization is caught immediately instead of returning incorrect matches.

Use NowSafe when reading CallContext.Now in ls

This line bypasses the new zero-value guard and reintroduces silent year-0001 behavior when CallContext.Now is unset. Before this refactor, an unset Now (nil function) failed fast; after the type change to time.Time, direct ls handler calls (or any future runner regression that forgets to set Now) will produce incorrect long-format timestamp cutoffs instead of surfacing the invariant violation. Using callCtx.NowSafe() here preserves the intended fail-fast contract introduced in this commit.
