test: isolate fixture commits from signing configuration - #258
When a developer enables commit.gpgsign, disposable test repositories inherit that setting and can fail or wait for a signing key or agent. Disable signing in the shared integration fixture's local configuration so the initial commit, later commits, and linked-worktree commits succeed independently of the developer's signing setup.
Apply the same local setting to the sparse fixture, and use command-local overrides for nearby single-use fixture commits. Add regressions with an isolated signing-enabled Git config and a harmless failing/recording signer, including a control that proves the signer would otherwise be invoked and checks that the global config remains unchanged. Give the test process a disposable home and XDG configuration directory so Git 2.17 also reads the controlled signer configuration.
Motivation
Reproduced on base 849e590: shared fixture setup exits 128 with gpg failed to sign the data. An override applied only to the initial commit still fails the subsequent-commit and linked-worktree regressions.
Type of Change
Bug fix (test fixtures)
Testing
Tested on macOS with Bash 3.2.57, Git 2.50.1, and BATS 1.14.0.
All three new signing regressions pass. Both fixture regressions fail before the fix; an initial-commit-only override also fails both later-commit checks.
Full suite across 42 files, run separately with four workers and independent Git/XDG state per file: 990 passed, 2 failed, 0 skipped. Signing was enabled with the harmless signer; there were zero unexpected signer invocations.
The two failures are existing Readline PTY tests in tests/completion.bats: “bash Readline accepts branch names literally in every quoting context” and “bash Readline accepts cd targets without standalone completion loaded.” Both hit the 15-second prompt deadline after gtr cd and reproduce on an untouched copy of base 849e590.
Repository CI ShellCheck command, generated-completion consistency check, and Git whitespace checks pass.
Follow-up compatibility validation: all three signing regressions pass on macOS/Bash 3.2 with Git 2.50.1 and in a network-disabled Ubuntu 18.04 container with Git 2.17.1. On Git 2.17.1, the previous test fails and invokes an ambient fake signer; the corrected test passes without invoking that signer, and both ambient home/XDG config files remain byte-for-byte unchanged.
CI on the initial PR commit passed Linux tests, macOS/Bash 3.2 tests, ShellCheck, and completion consistency.
No real signing keys or agents were accessed. Windows was not exercised locally.
Breaking Changes
None. This change affects disposable test fixtures only and introduces no dependencies.
Checklist
Read CONTRIBUTING.md and followed repository style.
Added meaningful regression coverage and validated on macOS.
Preserved intentional configuration tests and documented validation limitations.
Checked generated completions; no command or flag changes require regeneration.

Summary by CodeRabbit
Tests
Made repository fixtures more reliable when Git commit signing is configured, preventing setup commits from unexpectedly invoking a signer.
Added coverage to verify signing behavior in isolated configurations, including that integration-repository and linked-worktree commits succeed without invoking the configured signer and that global Git configuration remains unchanged.
Updated additional test fixtures to disable signing for setup commits, reducing failures caused by local signing preferences.

Walkthrough
Test fixtures now disable Git commit signing through local repository settings or command-local overrides. New Bats tests verify that fixture and linked-worktree commits avoid the configured signer while global signing configuration remains unchanged.
The shared integration and sparse fixtures set local signing configuration. Single-use fixture commits use command-local overrides. Comments describe related test coverage.
Verify signer behavior tests/fixture_signing.bats
New tests confirm that a signing-enabled control commit invokes the failing signer, while integration and linked-worktree fixture commits succeed without invoking it. The tests also check that global configuration remains unchanged.
Fixture commits are isolated from inherited signing configuration. No actionable merge-blocking risk remains.

isolate older Git versions that ignore GIT_CONFIG_GLOBAL: set HOME and
XDG_CONFIG_HOME to temporary locations and point GIT_CONFIG_GLOBAL at the
temporary home’s .gitconfig, preserving GIT_CONFIG_NOSYSTEM.
