On Windows, subprocess text=True without an explicit encoding decodes
child output with the ANSI code page (e.g. 'gbk'); non-ASCII bytes then
raise UnicodeDecodeError inside subprocess._readerthread, killing the
Hermes backend before it becomes ready and surfacing as the desktop boot
timeout.
Sweep every hermes_cli text=True subprocess call to encoding='utf-8',
errors='replace', and add an AST-based regression test that fails when a
future text-mode call omits the encoding.
Fixes#55658
The saved update_url is what the gateway urlopen()s unattended every
check interval, and the feed decides which origin commit an update
selects. Install copied it into the row inside a try/except-pass with
no scheme check, so http:// (MITM to an old vulnerable commit),
file:// and ftp:// feeds were accepted.
One predicate (plugins_updates.https_update_url) is applied at install
(a refusal before any state exists — the manifest was already read, so
the re-read/except-pass is gone), in trust-update-url, and at
default_fetch itself so rows saved before this rule are refused too.
- 15 `MERGE-CHECK:` conflict-resolution comments removed from prod code (two were
TODOs already done: the utf-8-sig sessions.json read lives in session_persistence,
the pm-aware cron script helpers in scheduler_script).
- 49 imports the branch left unused (ruff F401, none present at the merge base,
none inside PLUGIN-COMPAT blocks). update_cmd's frozen-surface re-exports are
trimmed to the names tests/compat/old_updater_surface.json actually lists under
hermes_cli.update_cmd; the rest resolve through hermes_cli.main.__getattr__.
- tools/environments/local_gitbash_probe.py: nothing imported it once _find_bash
delegated to pm.shell().
- Three try/except wrappers around calls that cannot raise (install_truststore,
get_hermes_home, and a duplicated except clause in supermemory).
Activation reaches plugin discovery before the application dependencies
exist. Give PM its own locked Python project and runtime so it can install
or repair the application without importing that dependency tree.
Keep PM outside the application workspace. A shared uv workspace resolves
the application graph and cannot provide this isolation. Route mutations
through an isolated worker and preserve transaction callbacks, cancellation,
custom package registrations, and correlated receipts.
Use the same runtime builder for source installs and packaged payloads.
Keep offline wheelhouse support in that builder. Nix builds the independent
PM lock as a separate derivation. Refuse lazy-disabled bootstrap before
installing tools or dependencies.
Move first-party YAML readers and writers to ruamel. Keep the application
lock's transitive PyYAML requirements for third-party packages.
Verification:
- Focused canonical Python suite: 177 passed, 1 host-gated skip.
- Electron backend probes: 12 passed. Electron typecheck passed.
- Both uv locks, scoped lint, Bash syntax, and whitespace checks passed.
- Cold activation, corrupt-app repair, offline staging, and relocation ran.
- Built and exercised the Nix PM runtime and standalone YAML merge script.
Six broader caller test files retain the same 24 failing test IDs as an
archive of HEAD. The existing real-home guard blocks those tests before
they can exercise the affected paths. No full-suite pass is claimed.
Native Windows signing and full Bionic package execution remain unverified.
Different text is not necessarily a newer version. Use the same
parsed comparison for approved feeds and PyPI. Parse each pair once.
Keep invalid versions unknown and explain them in the result.
The cadence test shows that an invalid feed cannot request an
automatic update. Git SHA and catalog-pin comparisons are unchanged.
Verification: 55 tests passed across checks, cadence, catalog and
transaction paths. Network replies were injected at existing seams.
No remote plugin was changed. Lint passed.
Keep upstream's reviewed catalog as the only plugin name index.
Catalog pins and custom update sources share staged PM validation.
Publish code and dependencies with recovery after process death.
Reject a concurrent enablement change before publishing disabled code.
Use the manifest loader's supported version in the installer. Keep
probe cooldowns for timeouts, not TLS failures that a CA change fixes.
Preserve the backup, uninstall, browser and memory-provider repairs.
Verified with the canonical runner on native Windows ARM64, real Git
repositories, local TLS endpoints and UV dependency generations.
Desktop catalog tests and both TypeScript checks pass. The full suite
and native release builds were not run. No remote push.
Dependency publication now recovers interrupted config/facts changes before
activation and leases live generations during collection. Receipts retain
update correlation and failed steps across nested command boundaries.
Doctor and desktop surfaces report those failures through shared owners.
Move checkout updates out of the desktop facade. Stage a detached Windows
relaunch waiter before shutdown, with bounded handshake and process-birth
checks. Keep packaged lifecycle tests isolated from the installed app.
Native verification exposed two production races: cron maintenance imported
the interactive CLI and rewrote TERMINAL_CWD, and install-ID reads collided
with first publication. Use the existing owners and locks. Plugin checks
now run at startup and each due-gated housekeeping tick, not after 60 ticks.
Share updater-test mutation boundaries and remove collection-root fixtures.
Separate cold MCP startup from command latency and give the real HTTP drip
test enough time to reach body handling.
Root npm check passed, including packaging. The fixed-tree Windows Python
run reported 44557 passed, one failed, and 1404 skipped, plus one retry-only
HTTP test. Those final failures now pass in a 35-test bounded batch. A real
isolated gateway wrote startup and periodic plugin-check receipts.
Full final-tree CI, bundled Sandbox deployment, and actual App Installer
relaunch remain unverified. docs/pm-audit-status.md records these limits.
Prepare dependency generations before selecting them. Keep shipped tool
bytes separate from writable additions, and store facts beside their entries.
Validate proposed plugin sets before config publication. Restore the previous
config if the facts write fails.
Consolidate duplicate updater, backup, setup, and voice helpers. Repair
launcher selection, dependency consumers, download ownership, update feeds,
and native Windows process and file handling.
Verification: 206 changed/prior-failing Python files reported 4630 passed,
one failed, and 330 skipped. Fix the remaining Hindsight fixture boundary.
The final targeted rerun reported 234 passed and two skipped. The store
review regression batch reported 83 passed and one skipped. Desktop
TypeScript checks, 56 selected Electron tests, 24 release tests, and the
removed-import/compatibility guards passed.
This is an integration checkpoint, not full audit acceptance. The complete
Python suite has not run on this fixed tree. Crash-atomic plugin publication,
generation cleanup, receipt correlation, and packaged lifecycle acceptance
remain open in docs/pm-audit-status.md.
