## Two residual Windows fixes that were hanging from earlier commits.
### 1. `hermes gateway status` reported 2 PIDs per gateway — TWO bugs compounded
Diagnosed with psutil parent/child walk against live gateway PIDs:
**Bug A (the real one): `_get_parent_pid` silently failed on Windows.**
The helper shelled out to `ps -o ppid= -p <pid>`, which doesn't exist
on Windows — `FileNotFoundError` → returns `None` → the ancestor walk
terminated at `os.getpid()` alone. Consequence: the PID table scan in
`_scan_gateway_pids` couldn't filter out `hermes gateway status`'s own
launcher stub (a venv `pythonw.exe`/`python.exe` that matches the same
`-m hermes_cli.main gateway` pattern as the gateway). Every status
call saw "itself" as a second gateway.
Fix: `_get_parent_pid` now calls `psutil.Process(pid).ppid()` first
(psutil is a core dependency since 3dfb35700) and falls back to `ps`
only when `shutil.which("ps")` succeeds — matching the Windows-footgun
checker's "always guard `ps` / `wmic` / etc. with `shutil.which`" rule.
Before: `Gateway process running (PID: 21952, 46880)` — 46880 changing
on every call (the status invocation's own launcher, which died by the
time the next status call looked).
After (5 consecutive calls):
```
✓ Gateway process running (PID: 21952)
✓ Gateway process running (PID: 21952)
✓ Gateway process running (PID: 21952)
✓ Gateway process running (PID: 21952)
✓ Gateway process running (PID: 21952)
```
Ancestor walk on the fix: 14 PIDs (full chain through bash/explorer)
instead of the broken 1-PID set.
**Bug B (the cosmetic one): venv-launcher dedup.** Standard Windows
CPython venv behaviour is that `<venv>/Scripts/pythonw.exe` is a ~5 MB
launcher stub that spawns the base Python (`C:\\Program Files\\Python311
\\pythonw.exe`) with the same command line and waits. Our process
scanner sees two PIDs for every gateway: launcher + interpreter, same
cmdline. Bug A masked this by accidentally counting the status call
AS one of them; with Bug A fixed, we see both the real launcher and
real interpreter for the gateway process itself.
Fix: `_filter_venv_launcher_stubs` at the tail of `_scan_gateway_pids`
walks each matched PID's ppid via psutil. Any PID that's the PARENT
of another matched PID is a launcher stub — drop it, keep the child.
Scoped to Windows (`is_windows() and len(pids) > 1`) and no-ops when
psutil isn't importable.
Net effect: `gateway status` now reports one PID per gateway — the
interpreter — matching POSIX behaviour and user expectations.
### 2. `install.ps1`: bootstrap pip + auto-install platform SDKs
New `Install-PlatformSdks` function wired between `Invoke-SetupWizard`
and `Start-GatewayIfConfigured`. Fixes two related issues on fresh
Windows installs:
1. The tiered `uv pip install` cascade (introduced in 87fca8342)
correctly falls through when tier 1 `.[all]` fails on the RL git
deps, but the fallback tiers can silently skip SDKs from `[messaging]`
when there's a partial-resolve. Result: user sets `DISCORD_BOT_TOKEN`
in `.env`, fires up gateway, hits "discord module not installed".
2. `uv` creates venvs WITHOUT pip by default, so the user's escape
hatch (`pip install discord.py` in the venv) doesn't exist either.
The new function:
- Skips if `-NoVenv` (nothing to bootstrap into).
- Scans `~/.hermes/.env` for messaging tokens (TELEGRAM_BOT_TOKEN,
DISCORD_BOT_TOKEN, SLACK_BOT_TOKEN, SLACK_APP_TOKEN, WHATSAPP_ENABLED),
filtering placeholder values.
- For each token that's set, runs `python -c "import <sdk>"` to verify.
- If any import fails: runs `python -m ensurepip --upgrade` to bootstrap
pip into the venv (idempotent — no-ops if pip is already present),
then `pip install <spec>` for each missing SDK with specs mirroring
pyproject.toml's `[messaging]` extra to avoid version drift.
The `$ErrorActionPreference = "SilentlyContinue"` spans are not
cosmetic — PowerShell wraps native-stderr from a non-zero-exit
subprocess as a `NativeCommandError` that prints even through
`*> $null` / `2>$null`. Save + restore EAP over the import-probe
and pip-install blocks keeps the output clean.
Verified on this Windows 10 box:
- Initial state: telegram+fastapi+psutil present, discord+slack_sdk
missing (tier 1 `.[all]` had failed — `.tirith-install-failed`
marker in `%LOCALAPPDATA%\\hermes`).
- First run with discord+slack tokens in .env: detects both missing,
ensurepip (skipped — pip was already bootstrapped earlier this
session for telegram), installs `discord.py[voice]==2.7.1` +
`PyNaCl` + `davey`, installs `slack-sdk==3.41.0`. All imports
succeed on verify.
- Second run: all three SDKs report OK, function no-ops.
Pip spec strings mirror pyproject.toml's `[messaging]` extra verbatim
so a bump to the extra picks up here automatically — no drift.
### Files
- `hermes_cli/gateway.py`: `_get_parent_pid` rewritten (psutil-first);
`_filter_venv_launcher_stubs` added; `_scan_gateway_pids` dedups
launchers on Windows when it finds >1 match.
- `scripts/install.ps1`: new `Install-PlatformSdks` function (~85
lines); wired into the main flow at line 1438.
### Verification
- `venv/Scripts/python.exe scripts/check-windows-footguns.py --all`
→ `✓ No Windows footguns found (380 file(s) scanned).`
- `ast.parse` passes on gateway.py.
- `[System.Management.Automation.Language.Parser]::ParseFile` passes
on install.ps1.
- Live gateway (PID 21952, running since 12:33 today) survived 5x
stress loop of `hermes gateway status` without dying.
