Gate collect_log on a minimum agent version and bridge the agent version
store to the applications table so a staged build can actually be pushed.
update_app resolves an install source from the applications table alone; it
cannot see agentstore. A build could therefore be staged and current while no
application row existed at all, which is what the fleet was in: the agent was
unpushable. Staging is now the single source of truth - it packages the
current build and upserts the row in the same request, so the row cannot
describe a build that is no longer staged.
PARTIAL BUILD ADVISORY
This is steps 1-4 of a longer rollout and is deliberately incomplete:
- There is no push trigger yet. The registered package is resolvable and
verifiable, but nothing enqueues an upgrade; the "behind current build"
indicator is still display-only.
- The upgrade template script, its script row, and the enqueue route
(endpoints.agentupdate) are not written.
- Blocking constraint for the next slice: run_script executes
powershell.exe -File <script> with NO argument channel, so a delivered
upgrade script cannot be passed BaseUrl/CollectorKey and must either
source them itself or run_script must be extended first.
Nothing here touches a live endpoint. Staging only changes what a future
push would contain.
Details:
- Package members carry a fixed timestamp. zipfile stamps the current mtime
by default, so identical input produced a different archive digest on
every call. update_app pins a download by SHA-256, so a drifting hash
would rewrite installersha256 out from under an endpoint mid-download and
fail its verification.
- All three routes that can change 'current' re-register (upload,
adopt-legacy, rollback). Covering only upload would leave the row pinned
to the build an operator just rolled away from, and the push would ship
it anyway - silent drift.
- Registration cannot fail an upload. The binary is staged and audited by
the time it runs, so a packaging problem is reported in the response
payload rather than raised; returning an error would tell the operator a
successful upload was rejected.
- The package is written to a temp name and os.replace'd, so an interrupted
write cannot leave a truncated archive at the path the row advertises.
- The row is isinstallable but hidden: machine-managed, and it must not
appear in the software catalogue beside real licensed applications.
- Added application_package_location() to the shopdb.api contract surface
(lazy, matching collector_authorized) returning the package directory and
URL prefix together. agentregistry reached into shopdb.core internals,
violating the plugin import contract; sourcing both from one place also
stops the write location and installpath from drifting apart.
collect_log is refused at enqueue below its minimum agent version, with
numeric comparison - string ordering misplaces 1.9.0.0 against 1.16.0. The
refusal is mirrored in the UI so a command slot is not spent on a call that
is guaranteed to fail.
Test isolation: create_app('testing') resolves instance_path to the real repo
instance/ directory, so agent upload tests write into the developer's actual
store. The new tests redirect both the store and package output into tmp_path
and include a guard test that fails if that isolation regresses. NOTE: the
pre-existing test_endpoints_agentupload.py still has this leak and deposits
1.5.0.0 and 1.6.3 into instance/siteagent/ on a full run - not fixed here.
Suite: 2834 passed, 11 skipped. The two failures (test_docs_publishable, and
a symlink scan needing Windows privileges) were confirmed pre-existing by
stashing this work and reproducing them.
Mapped drives stopped reporting because the user-context path failed silently
in three separate places, and none of them left a trace to read back.
- Probe: launch via -EncodedCommand instead of staging a temp .ps1 and running
powershell.exe -File. A missing or quarantined script file fails BEFORE any
statement runs, so the script's own try/catch never sees it and the only
symptom is exit -196608.
- Spool: pin to the ShopFloor profile. Resolving it through WTSQueryUserToken
is privileged, endpoint protection blocks it, and on failure the tray
(writer) and service (reader) silently disagree about the path.
- Spool: consume after a successful parse, so a stopped tray cannot keep
re-reporting stale mapped drives as current. Unparseable files are left in
place for the next cycle.
- Logging: user-session components cannot write to Program Files or to the
SYSTEM-owned ProgramData log directory, and the file sink degrades to a
silent no-op when it cannot create its directory. Tray and probe now log to
C:\Users\ShopFloor\ShopDB\Logs, installs transcript to ProgramData, and the
sink records a SinkProblem instead of swallowing UnauthorizedAccessException.
- Installer: provision the operator spool/log directories with ShopFloor:Modify
before the tray first runs, and stop the transcript via trap so a throw
cannot orphan exactly the failed install worth reading.
- Upload cap 64 -> 128 MB: the self-contained tray publishes at ~69 MB and was
rejected on SIZE, but the size check returns before the PE is parsed, so the
operator only ever saw a version-detection failure.
AGENT-CONTRACT.md gains a normative section defining the three security
contexts, their log destinations, the fixed spool path and consume-on-read.
Agent 1.8.0 -> 1.8.1, tray 1.1.0 -> 1.1.1 so the deployed build is
identifiable from a log line.
Uploading an agent build whose product version carried semver build metadata
(1.5.0+abcdef) was rejected, because the typed version string was validated as
a dotted-numeric value before the file was ever read. That string is only a
hint from the operator, and the build metadata it carries is not a legal
directory name for the version store.
The authority is the dotted-numeric FILE version stamped in the binary PE
resource, so validation now happens after the upload is parsed: when the typed
value is missing or not dotted-numeric, fall back to the detected version, and
reject only when neither yields a usable one.
