Jinjing 637c7e94c9 Add SSH config host picker to add-host dialog (#12334)
* feat(ssh): add SSH config host picker for add-host form

Users can now click 'Fill from ~/.ssh/config…' to browse available SSH
config hosts in a picker, select one, and have the form automatically
prefill with resolved connection details (hostname, port, username, auth).

Previously, an 'import' button provided bulk sync on this form—confusing
and unhelpful when everything was already synced. That action is now
available as a secondary 'Add all' option in the picker.

* fix(ssh): import filter preservation and label fallback

- Reuse search loader on import completion to preserve active filter inside generation guard
- Fall back to hostname when manual host has no label, not empty string
- Make alias duplicate detection case-insensitive to match config picker behavior
- Validate host availability when restoring project group selection
- Add aria-selected attribute to picker options for accessibility

* fix(ssh): harden config picker import, alias folding, and host targeting

Review findings on the ~/.ssh/config picker + bulk add:

- Guard config-host resolution with a generation counter so a late resolve
  cannot overwrite a later pick or a form the user backed out of; freeze the
  other rows while a pick resolves.
- Stop "Add all N" from re-adopting deleted hosts — it now imports without
  reAdopt, matching the new-host count it advertises. Settings → Import keeps
  the explicit re-adopt path.
- Fold SSH aliases through a shared normalizeSshConfigAlias for import
  ownership, delete tombstones, reclaim, picker search, and the save-time
  duplicate check, which now occupies configHost *and* label like the picker.
- Persist GSSAPIAuthentication only when a parsed Host entry asks for it, not
  when `ssh -G` merely echoes the /etc/ssh system default.
- Fail closed with unavailable/setup-not-found when an explicit
  projectHostSetupId names a non-actionable host instead of silently creating
  the workspace on a sibling host.
- Cache the parsed config for the picker session (refresh on open/retry) so
  filter keystrokes no longer reparse and Include-expand the file, keep the
  filter usable during loads, add a Retry on load errors, explain an empty
  Identity file after a config fill, and drop the always-false aria-selected.

* refactor(ssh): centralize host result limit and extract folder group val

Move SSH_CONFIG_HOST_RESULT_LIMIT to shared types so the renderer's limit message
cannot drift from the host's query limit. Extract findActionableFolderProjectGroup
to avoid repeating the folder-host-availability check across the composer hook.

* fix(ssh): pass -F to ssh -G when HOME differs from passwd home

In E2E tests and sandboxes, isolated HOME can differ from the system
passwd home. OpenSSH resolves the default config via getpwuid (passwd),
while Node's loadUserSshConfig uses os.homedir() (HOME-aware). Pass -F
to explicitly specify the config path when they diverge, so ssh -G and
the picker resolve the same file.

* fix(ssh): verify config host exists before resolving with ssh -G

When a user edits ~/.ssh/config and removes a host, the import picker
should not fall back to ssh -G's echoed response (which treats any alias
as valid). Check the reloaded config file before resolving.

- Force reload config on each resolve to catch user edits post-open
- Reject aliases not in the current config before calling ssh -G
- Add test for deleted alias edge case
- Fix workspace-target fallback to honor explicit host selection

* fix(ssh): let tombstoned aliases be re-picked in the config picker

Allow users to reclaim a deleted SSH host by re-picking it from ~/.ssh/config. Tombstoned aliases now appear in the picker with a "Removed from Orca" badge and remain pickable, but don't count toward "Add all" operations — ensuring passive import never resurrects a deleted alias while still giving the user a recovery path.

# E2E Test Plan: SSH config host picker (`import-ssh-config-does-nothing`)
## Branch summary
Users can open **Fill from ~/.ssh/config…** on the add-SSH-host dialog, pick a
Host alias, and get the form prefilled from `ssh -G` resolution. Bulk sync is a
secondary **Add all N to Orca** action (no re-adopt). Settings → SSH → **Import**
remains the deliberate re-adopt path.
Commits under test (vs main):
- `bd0b594dee` feat(ssh): add SSH config host picker for add-host form
- `dc8339369a` fix(ssh): import filter preservation and label fallback
- `5982c8108f` fix(ssh): harden config picker import, alias folding, host targeting
- `5cfb6369e7` refactor(ssh): centralize host result limit / folder group helper
## Already covered (do **not** re-test in E2E)
| Area | Where |
|------|--------|
| `listConfigHosts` / `resolveConfigHost` IPC registration | `src/main/ipc/ssh.test.ts` |
| Search, result limit, suppressed aliases, alreadyInOrca | `ssh-config-host-picker.test.ts` |
| Generation guard, freeze-while-resolving, late resolve | `AddRemoteHostDialog.config-picker.test.tsx` |
| Bulk `importConfig()` without `reAdopt` | `add-remote-host-ssh-actions.test.ts` |
| Alias folding / duplicate save check | `ssh-target-duplicate.test.ts` |
| `configured-only` host registry / setup fail-closed | unit tests in shared + project-host-workspace-target |
| Settings modal viewport stability | `ssh-host-form-modal.spec.ts` |
E2E is reserved for real Electron HOME isolation, real `~/.ssh/config` parse,
real `ssh -G` resolve, and user-visible DOM outcomes.
## Harness requirements
1. **Isolated HOME** — E2E already sets `HOME` to `{userDataDir}/home`. Seed config with:
```ts
const home = await electronApp.evaluate(({ app }) => app.getPath('home'))
mkdirSync(path.join(home, '.ssh'), { recursive: true, mode: 0o700 })
writeFileSync(path.join(home, '.ssh/config'), configBody, { mode: 0o600 })
```
2. **Unique aliases** — prefix Host entries and Orca labels with
`e2e-ssh-cfg-${Date.now().toString(36)}-…` so workers never collide; clean up
via `window.api.ssh.removeTarget` in `afterEach` by label/configHost prefix.
3. **Open the picker dialog** (not Settings `SshTargetForm` — that form has no
config picker). Path:
- Open **Add Project** (sidebar / landing control)
- Host combobox → **Add remote host** → **Add SSH host**
- Dialog title **Add SSH host** with link **Fill from ~/.ssh/config…**
4. **Assertions** — DOM only (`getByRole`, `toHaveValue`, visible badges/toasts).
Store/API only for setup/cleanup/seeding existing targets.
5. **Prereq** — OpenSSH client on PATH (`ssh -G`). macOS/Linux CI has it; skip
or soft-fail only if `ssh -G` is unavailable (document in test comment).
## Spec file
`tests/e2e/ssh-config-host-picker.spec.ts`
Reuse patterns from `ssh-host-form-modal.spec.ts` (session ready, target cleanup,
announcement dismiss). Prefer small local helpers over new shared modules unless
helpers would be reused elsewhere.
Optional second file if the Settings Import case grows:
`tests/e2e/ssh-config-import-settings.spec.ts` — otherwise keep Import in the same file.

## Cases (must ship)
### P1 — Empty config empty state
| | |
|--|--|
| **Setup** | Do not create `~/.ssh/config` (or write empty file). |
| **Steps** | Open Add SSH host → Fill from ~/.ssh/config… |
| **Expect** | Dialog title **Choose from ~/.ssh/config**; body **No hosts in ~/.ssh/config**; **Add all to Orca** disabled; **Back** returns to form. |
### P2 — Seeded hosts listed with summary lines
| | |
|--|--|
| **Setup** | Write config with ≥2 concrete Hosts, e.g. `e2e-alpha` / `e2e-bravo` with HostName, User, Port. |
| **Steps** | Open picker. |
| **Expect** | Host list `SSH config hosts` shows both aliases; subtitle `user@hostname:port`; button **Add all 2 to Orca** enabled. |
### P3 — Select host prefills form (and Save persists)
| | |
|--|--|
| **Setup** | Config Host `e2e-prod` → HostName `prod.example.test`, User `deploy`, Port `2222`. |
| **Steps** | Pick `e2e-prod` → wait for form → click **Save**. |
| **Expect** | After pick: Host/alias field = `prod.example.test`, Username `deploy`, Port `2222`, Label `e2e-prod` (or alias); optional toast *Filled from e2e-prod*; Identity file may stay empty with config hint. After Save: dialog closes; target appears in Settings → SSH (or listTargets shows matching host). |
### P4 — Filter narrows list
| | |
|--|--|
| **Setup** | Hosts `e2e-alpha`, `e2e-bravo`. |
| **Steps** | Open picker; filter `bravo`. |
| **Expect** | Only bravo row; alpha gone; **No matching hosts** if filter is nonsense. |
### P5 — Already-in-Orca badge + disabled row
| | |
|--|--|
| **Setup** | Config hosts alpha + bravo. Seed Orca target with `configHost`/`label` matching alpha (via `ssh.addTarget`). |
| **Steps** | Open picker. |
| **Expect** | Alpha shows **In Orca** badge and is not clickable; bravo still selectable; **Add all 1 to Orca** (not 2). |
### P6 — Add all N to Orca imports new hosts only
| | |
|--|--|
| **Setup** | Config with 2 new hosts; no Orca targets for them. |
| **Steps** | **Add all 2 to Orca** → wait for success toast / return to form or list refresh. |
| **Expect** | Both targets exist (DOM in Settings SSH and/or listTargets); re-open picker shows **All hosts already in Orca** / both **In Orca**. |
### P7 — Add all does **not** re-adopt deleted hosts
| | |
|--|--|
| **Setup** | Config with alpha + bravo; Add all → remove alpha via API (creates suppress tombstone). |
| **Steps** | Re-open picker; note count; optionally click Add all again. |
| **Expect** | Alpha absent from picker (suppressed) or not re-created; only new hosts counted; `listTargets` still lacks deleted alpha after second Add all. |
### P8 — Back discards pending pick path
| | |
|--|--|
| **Setup** | Seeded config. |
| **Steps** | Open picker → **Back** without selecting. |
| **Expect** | Form fields still empty (Host blank); no filled toast. |
### P9 — Settings Import re-adopts (contrast with P7)
| | |
|--|--|
| **Setup** | Same as P7 after delete. |
| **Steps** | Settings → SSH → **Import** (explicit reAdopt path). |
| **Expect** | Deleted config host reappears as an Orca target; toast sync count ≥ 1. |
---
## Nice-to-have (only if cheap after P1P9)
- **N1** ProxyCommand / JumpHost: pick host with ProxyJump → Advanced opens and jump field filled (proves advanced prefill + `preferAdvancedOpen`).
- **N2** Case-insensitive alias: config `Prod`, existing label `prod` → **In Orca**.
- **N3** Empty Identity file hint visible after config fill.
Skip: 100-host truncation, resolve races, GSSAPI system-default, composer host-availability fail-closed (unit-covered).
## Out of scope
- Real SSH connect / relay / PTY
- Docker SSH fixtures
- Web client stub paths (`listConfigHosts` returns empty)
- i18n non-English
## Implementation status (done)
| Case | Spec |
|------|------|
| P1 empty state | `ssh-config-host-picker.spec.ts` |
| P2 list + Add all enabled | `ssh-config-host-picker.spec.ts` |
| P3 select + Save (+ N3 identity hint) | `ssh-config-host-picker.spec.ts` |
| P4 filter | `ssh-config-host-picker.spec.ts` |
| P5 In Orca badge / count | `ssh-config-host-import.spec.ts` |
| P6 Add all imports | `ssh-config-host-import.spec.ts` |
| P7 no re-adopt after delete | `ssh-config-host-import.spec.ts` |
| P8 Back without select | `ssh-config-host-picker.spec.ts` |
| P9 Settings Import re-adopts | `ssh-config-host-import.spec.ts` |
Shared helpers: `tests/e2e/helpers/ssh-config-host-picker.ts`
### Product fix required for E2E (and real HOME isolation)
OpenSSH resolves the default user config via **getpwuid**, not `$HOME`. E2E
sets an isolated `HOME`, so `loadUserSshConfig` (Node `os.homedir()`) and
`ssh -G` could disagree. `src/main/ssh/ssh-g-config-resolution.ts` now passes
`-F <homedir>/.ssh/config` when the HOME config path exists and differs from the
passwd home. Normal installs (HOME = passwd home) are unchanged.
