A site adopting this app arrives holding procedures already written: styled
HTML pages that get mailed around, opened off a share, and edited by whoever
still has the file. Those pages are exactly what a guide is for, and retyping
one into the editor is how a good procedure stays on a share forever.
flask guides import-html reads the page and produces blocks. It recognises the
vocabulary those pages actually use - a step box with its own number, an alert
in one of three colours, a code block with a copy button, a checkbox list, a
table with a header row - and maps each to the block that already renders it,
lifting embedded images into guideimages so a document stops carrying its
screenshots as base64. Page furniture goes: the header, the footer, and the
table of contents a guide builds for itself from its own headings.
The conversion is lossy on purpose. Colour, fonts, width and nested layout are
dropped, because storing blocks rather than markup is what makes dark mode,
printing and tickable steps work at all. So an import is always a DRAFT and the
default is a dry run that reports what it would produce and writes nothing.
Blocks go through the same validator the API uses: an import must not be able
to store something the editor could not have produced.
The parser is tolerant, because real articles are not well-formed. An unclosed
<p> is normal HTML and the browser closes it at the next block element; without
the same rule one unclosed tag swallows the rest of the article into a single
paragraph, which is what it did before the test caught it.
Proven end to end against four real articles, including one carrying two PNG
screenshots, read back in a browser.
POST /api/reports/email has always taken any {columns, rows} from any caller,
but the Email report button existed on the toner and warranty pages only - not
because those reports are special, but because they happen to be their own
routed pages and the reports page had no button at all. It is now beside Export
CSV for every report the page can build a table from, which is all of them:
plugin reports through their declared columns, core reports through the flat
list they return, and the asset inventory summary by flattening its three
tables into one with the grouping named in a column. Presentation-only fields -
a status colour, a link id - are left out; a column of hex codes is worse than
no column. The shapes live in a module with tests rather than in the view.
The button is now hidden without reports.export on all three pages. Offering
somebody a button that can only answer 403 is worse than not offering it.
Separately, on the USB kiosk a long drive name pushed Take or Return out
through the side of its card, leaving a drive nobody could press. The name is a
flex item and so defaulted to min-width:auto, keeping its full intrinsic width;
it now yields, wraps mid-word for the serial-style names that carry no spaces,
and clamps its description to two lines so one long name cannot make every card
in the row tall. The locker line is never clipped - it is how somebody finds
the drive.
A cabinet of thirty drives was one long column to read through. The free list
now filters from a search box and lays out in as many columns as the panel is
wide - four on a wall display, two on a tablet, one on a phone - while the
steps that hold a single control stay narrow, because stretching one input
across a 24 inch screen reads as a broken page.
A drive is found by its id, by what is written on it, or by where it lives. The
words can arrive in any order, and "locker" is part of what is searched, so
"locker engineer" finds the engineering locker - that is how people say it out
loud. Filtering is client-side: every free drive is already on the screen, and a
round trip per keystroke on a wall panel would be worse than no filter at all.
The matcher lives in its own module with tests rather than inside the view.
The box takes focus as the picker opens so somebody can simply start typing,
and it is cleared when the kiosk resets - the next person at the cabinet must
not inherit a filter and conclude there are no drives left.
Also: both this view and the guides blocks coloured muted text with a
`--textmuted` variable this app has never defined. The browser dropped the
declaration, so every hint, subtitle and locker line was rendering at full
strength. The variable is `--text-light`.
The reports page ran a hardcoded switch over five core report ids and fell
through to `default: console.error('Unknown report')`, and its results panel was
a matching chain of per-id templates ending in a `JSON.stringify`. So a plugin
could register a report, watch it appear in the catalogue, and get a wall of
JSON when it was opened - which is where the three printedparts reports have
been since they were added.
Any report that declares an endpoint is now fetched from it, and any report
returning {columns, rows} renders as a table. That shape is already the
convention on the server side, so a plugin needs no core code at all to have a
working report. The per-id templates stay for the core reports whose payloads
are not tabular.
Export CSV goes through the api client rather than window.open. A new window
carries no Authorization header, so every report behind a real jwt_required -
which is every plugin one - answered the export button with a 401. The core
reports are jwt-optional, which is the only reason the old way ever appeared to
work. It also followed /api/reports/<id>, which does not exist for a plugin
report, instead of the endpoint the report itself came from.
A report that fails now says so instead of leaving an empty panel, and the page
offers the time window the endpoints already accepted - printedparts-consumption
was permanently stuck on its 30-day default because nothing could send one.
Verified in a browser against both plugin report families and the core reports.
CMMC removable-media tracking is an audit obligation, and answering "who had
this drive, and when" meant paging through the check-in/out list by hand.
GET /api/usb/reports/audit returns the events - a take and a return are separate
rows, because a count cannot answer the question an audit actually asks - with
summary figures riding along for the people who only want the shape of it, and
a CSV for the people who want it in a spreadsheet.
The window is named rather than a day count: today, last month, six months, a
year, all time. Nobody should have to work out that a year is 365.
Both directory modes answer in one voice. The external path reads the
cmmc_usb checkinoutlog; self-hosted expands one usbcheckouts row into its two
ends, so a returned drive is distinguishable from one still out, and the window
filter runs in SQL against either end of the loan - a drive taken before the
window and returned inside it is a check-in the window has to show. Rows come
back from the mode-specific half; the CSV, the summary and the response shape
are built once in the route.
Ordering is total in both modes. Timestamp alone ties for two events in the same
second, and the same query then returns them in a different order each run,
which reads as the log being unstable.
Guides was shipped without an entry in PLUGINS.md or START-HERE, so a site
adopting the product had no way to find out it exists.
BACKUP-KINDS.md described a host's badge as coming from the most recently
confirmed kind. It has not worked that way since the fleet report was reworked:
the freshest revision per (host, kind) is taken, and then the STALEST of those
kinds decides, because reporting the freshest would let a healthy NTLARS backup
mask a part-marker capture that stopped a month ago. Stalest among kinds that
can be JUDGED - a kind never confirmed is unmeasurable, not stale, and treating
it as the worst value made a host with a working backup show no badge at all.
The backups row also still advertised UDC and CMM kinds that do not exist.
api-inventory, openapi.json and PROJECT-MAP regenerated.
The printer feature rests on one rule: a collector report is OBSERVED state and
never ASSIGNED state. If a drifted bay's own state can become what it is told to
install, enforcement stops meaning anything, because a bay that installed the
wrong printer makes itself right simply by reporting it.
_sync_printer_links broke that rule. It ran on every collector PC push and, when
the payload carried defaultprinter or printers, wrote defaultprinter and
connectedto rows from the report - defaultprinter being one of the two types
_reconcile_edges is meant to own alone, from authenticated routes a human calls.
It was recorded as dormant. It was not. The collector schema ADVERTISED both
keys and the example client in COLLECTOR-INTEGRATION.md set
$payload['defaultprinter'], so the documentation was recruiting callers for it -
while the same document, under "Observed is not assigned", promised that nothing
on this path writes a usesprinter or defaultprinter row. The document
contradicted itself and the code followed the wrong half. Nothing in the fleet
armed it, because the first-party reporter never sent those fields, but any
third-party client written from the docs would have.
Retired the function, its _sync_one helper and the now-unused
PRINTER_LINK_ORIGIN label, and removed both keys from the schema.
IGNORED, NOT REJECTED. Unknown payload keys are not validated, so a client
written against the old docs keeps pushing successfully and only its printer
keys stop doing anything. The response warns, naming the keys and pointing at
POST /api/collector/printers for reporting queues and seed-from-observed for
adopting them. Dropping them in silence would leave an integrator believing
assignments were still being written, which is a worse failure than the one
being fixed.
The docs were the larger half of this. The schema table rows are gone, the
"PC -> printer relationship sync" section is replaced by a note saying what
happens now to anyone still sending the keys, and the example client no longer
enumerates Win32_Printer at all - it points at Report-PrintersToShopDB.ps1,
which posts to the observed endpoint and posts NOTHING on a failed enumeration,
since an empty list would erase the host's rows.
test_collector_printers.py pinned the old behaviour, so it now pins the
opposite: the keys create no relationships, the push still succeeds and says
why, a payload without them stays quiet, a human-made default survives a report
naming a different printer, and the schema no longer offers the keys.
Reported: the warranty page cannot be searched by machine number.
It was there to be found. _related_machine puts the machine's number in the
payload, and it does so for a stated reason - a shopfloor PC is bought,
warranted and replaced as a PC, but it is FOUND by the machine it drives, and
nobody walks the floor looking for an asset number. The table renders it as a
chip. The filter looked at vendor, service level, service tag and asset number,
and never at the machine. So the one identifier the feature was designed around
was the one thing the search box could not match.
This is how a field list goes wrong: a column was added to the table and not to
the filter, and nothing connects the two. Moved the field list into
warrantySearch.js so a test can see it, following controllingPc.js and
labelPages.js. Machine name is searched as well - somebody who knows the bay by
"the Makino" should not have to look up its number to find its warranty.
The specs also pin the case that made the old inline version fragile: a covered
asset whose machine is null, which is every printer and any PC nobody has linked
yet, must not throw. And a missing field must not match: String(undefined) is
'undefined', so a naive coercion makes a search for "und" hit every row with an
empty vendor.
Not changed, worth knowing: the covered asset's NAME is still not searched, only
its number. That looks like the same omission, but it is a wider change than the
report - the placeholder has always said "asset" without saying which half - so
it is left for a deliberate decision rather than folded in here.
Reported: `flask plugin upgrade-all` failed the tools plugin with "table
securesendsecrets already exists".
Every post-cutover baseline emitted a plain op.create_table. That is correct
only while a table's existence and its plugin's Alembic stamp can never
disagree, and they can. Anything that builds tables from the models -
db.create_all(), which `flask db-utils create-all` calls - creates them and
stamps nothing. A run that creates a table and then fails before its stamp
commits leaves the same split, and re-running is the obvious thing to try. In
both cases upgrade-all meets existing tables with an unstamped chain and the
create is fatal.
Nothing caught it because the migration test DROPS the post-cutover tables
db.create_all() built before running upgrade-all. That arranges the one state
where an unguarded create works, and never the state the report came from. The
new test is the same sequence with the drop removed for the plugin under test.
create_table_if_missing and create_index_if_missing are in alembic_template.py
next to create_plugin_tables, which had the idempotency rule right and turns out
to be called by nobody - its docstring claimed every 0001 used it. Fixed the
docstring rather than rewiring the baselines onto it, because the reason they
hand-write their DDL still stands: the helper's per-plugin MetaData cannot
resolve a foreign key to a core table at CreateTable-compile time.
INDEXES ARE MATCHED ON COLUMNS, NOT NAME, and that distinction matters. The two
creators disagree about names - db.create_all() takes SQLAlchemy's default
convention (ix_securesendsecrets_token) and a baseline spells it the way this
repo's naming rules require (ixsecuresendsecretstoken). A name-keyed guard would
have called the index missing and added a second one over the same column, which
MySQL permits with a warning, so every affected site would have quietly grown
duplicates. The test asserts no table ends up with two indexes over the same
columns.
Applied to all nine table-creating plugin migrations, not just the tools
baseline that was reported: the four later migrations that create tables have
the same exposure, and geenforce, measuringtools, printedparts and backups are
the same defect waiting for a different site.
WHAT THIS DOES NOT FIX. It makes a baseline idempotent, not a whole chain. A
longer chain can still meet an ALTER whose column is already present -
printedparts adding gagelabtag to a table create_all built at head is the case
that showed up while testing. Guarding every op one at a time is the wrong
answer to that; a database built from the models is already AT head and its
chains want stamping rather than replaying, and there is no `flask plugin stamp`
today. Left alone deliberately rather than half-built, and the new test is
scoped to single-baseline plugins so it does not pretend otherwise.
Reported: moving machine 3016 on the map and saving answered "this
relationship already exists" and refused the save.
The map had nothing to do with it. Every save of the machine form re-POSTed the
controlling-PC link, and the server was right to refuse it - the row was already
active, and assetrelationships is unique on (source, target, type). Any edit to
a machine that has a controlling PC hit this; a position change is just the one
somebody happened to be making.
The form asked the wrong question. It used "do I know the existing link's id" as
a stand-in for "is there an existing link", and read that id from
rel.assetrelationshipid - a key the API has never emitted. to_dict serialises
column names and the column is relationshipid, so the read was undefined on
every load while controllingPcId was populated from the same relationship. The
two answers disagreed, and the disagreement was invisible: undefined is not an
error, it is just a falsy id.
That single conflation caused both failures. Saving anything re-created the
link, and CLEARING the controlling PC did nothing at all, because "no selection
and no known id" reads as "nothing to do" - so removing a machine's controlling
PC silently kept it. Only the first of those was reported, and the second is the
one somebody would have trusted.
Fixed by making the LOADED PC the authority on whether a link exists, with the
relationship id used only to delete a row. If that id ever goes missing again
the worst case is a link that cannot be removed, never a duplicate create.
The decision moved to controllingPc.js as a pure function so it could be pinned
by tests, following labelPages.js. Unchanged is now explicitly no-op rather than
delete-then-create: re-linking a machine to the same PC opens a window where it
has no controlling PC at all, and resolve_asset_position walks that edge, so a
failure between the two calls would drop the machine's inherited position along
with its link. The specs also cover a select handing back '42' against an API
that gave 42, which would make an untouched link look like a swap and reach the
same duplicate POST by another route.
Not the printer assignment, which was the first guess: PrinterAssignmentPicker
makes no relationship calls, and its save is wrapped in a catch that only logs,
so it cannot surface an error from this form at all.
Secure Send shipped on 21 August and nothing outside the code caught up. The
roadmap still listed it under Deferred as "tabled", and gave as the reason that
the tools plugin is browser-only by design with get_blueprint and get_models
both empty - which stopped being true in the same day's commits that gave it a
blueprint, a table, a migration chain, a permission and a setting. A reader
following the roadmap would have concluded the feature does not exist.
The generated API docs were fine: api-inventory.json and openapi.json both
carry /api/tools/secrets, so the contract gates did their job. What was missing
was every word written for a person, and that is the half where the security
properties live.
docs/SECURE-SEND.md is the new page. The parts worth having in prose rather
than inferring from the code: that a lost secret is lost to everybody including
an administrator, which is the same property as "a compromised database yields
nothing" seen from the other side; that the 4096-character limit is the entire
server-side enforcement, because a server that cannot read what it holds cannot
have an opinion about content, so raising it turns a password tool into an
unaudited file transfer; that redeeming is a POST because preview prefetch in
chat and mail clients would otherwise spend a one-view secret before the
recipient ever sees it; and that somebody should send a link to themselves
through their own mail or chat client and confirm the key survives after the #
before a real credential goes through it, because a product that rewrites links
can strip the fragment and nothing on this side can help.
securesend_allow_guests was in the database, on a settings page, and in no
document. It is now in CONFIG.md with what it actually does - an unauthenticated
write endpoint, rate limited per address, failing closed - rather than only its
one-line description.
Also corrected along the way: site_base_url was documented as scheme + host
while the code deliberately tolerates a subpath in it, and the bundled plugin
table in PLUGINS.md had no row for tools at all.
Still missing after this: PLUGINS.md has no row for backups either.
Reported as a barcode rendering 176 by 0. A bar height of zero is what does it:
the number went straight into a CSS length, height: 0in is perfectly valid, and
an image sized height: 100% of a zero-height box is zero pixels tall. The label
comes out full width with nothing on it, which reads as a rendering failure
rather than as a field doing exactly what it was told.
A cleared field was the same bug wearing a different hat. An emptied number
input holds '', not 0, so the page emitted `NaNin`; the browser dropped the
declaration and the box fell back to auto height. That one merely looked wrong
instead of vanishing, which is arguably worse for finding it.
Measurements now go through labelVars(), which will not emit NaN, an empty
length, or a zero for anything whose zero means the box stops existing. Padding,
the quiet zone and the gap still take zero, because there zero is a real answer,
and offsets stay signed. It is a separate module because this is exactly the
kind of arithmetic that needs tests rather than a preview: every case in
labelVars.spec.js is a value a number input can actually hold.
The stylesheet now carries fallbacks on its var() reads as well, but they are a
net, not the fix: a custom property set to garbage is substituted and then
dropped at computed value time, and the fallback does not apply - it only covers
a property that is absent entirely.
Reported as the CODE128 not appearing in the preview. It was appearing, in 44
of the 45 preset and layout combinations swept - as a 36 pixel stub. The code
box and the caption were both allowed to grow, so a caption of any length took
half the label and then kept taking, and on 1.00 x 0.50in stock a few words of
caption left a barcode too narrow to scan. Present, useless, and indisinguishable
from a failed render. The caption now takes the room it needs and no more, and a
CODE128 holds at least 40% of the label, or all of it when stacked: past that
there are too few narrow bars left to read, and a caption that wraps or clips is
the better trade.
So that a real failure can never again look like this one, an empty code box now
says so in red in the preview. It is screen-only - the marker must never reach a
printed label.
The settings were a narrow column with the preview trailing below them, which
put the labels being adjusted off the bottom of the screen. Settings on the
left, labels on the right in a column that stays in view and scrolls on its own,
folding back to one column on a narrow window.
That scrolling column is a print hazard worth naming: an ancestor with its own
overflow clips a multi-page print to whatever happened to be on screen. Print
resets it, and the check is a six-page two-sided run coming out as six pages
with the label as the only clipping box in the chain.
The back side landed last commit carrying text by default, and a back laid out
as text-only renders no code box at all. So a two-sided run came out with a
blank reverse, which reads as the code having failed rather than as a setting
doing exactly what it said. The back now defaults to carrying a code, takes its
own content per row, and chooses its own symbology - a QR on the front that
opens the record, a CODE128 on the back that the bench scanner already reads.
Text-only is refused while the back carries a code, and the contradiction is
reconciled on load, so a saved setting from the broken combination repairs
itself rather than printing another blank box of cards.
A picture can go on a label: above the code, beside it, or behind everything as
a watermark, on either side or both. The file is read in the browser and never
sent anywhere, which is what makes it usable at an air-gapped site, and it is
deliberately not saved between visits - a data URL runs to megabytes and would
take every sizing value with it when the quota gave out. The watermark says
plainly that it costs the scanner contrast.
The generator was a full-screen route with no navigation and a narrow column of
controls against the left edge. That shape exists so a print cannot put the
sidebar on label stock, which is a real hazard and the reason core's label pages
are built that way - but it is a hazard the print stylesheet can answer, and
style.css now hides the shell at print time. A tool someone spends ten minutes
in gets the navigation and the full width; the stock still gets nothing but
labels, confirmed against a print PDF rather than a preview.
Two smaller things found while checking the above. A test print paired each page
with a rendered code by loop position, while the codes are keyed to position in
the whole run, so a two-sided test card could carry the wrong code; the index
now travels with the page. And the back's dotted preview outline outspecified
the print reset, drawing a dashed rule down the edge of every second card.
Three things the code generator could not do, each of which had someone
working around it with a control that meant something else.
The gap between a code and its caption was the quiet zone. That is the
clear space a scanner needs around the code, so closing up a caption meant
shaving the thing that makes the code readable, and the only way to get a
tight label to scan was to push the caption further away than it looked
like it should be. Quiet zone now means the code's own margin and nothing
else; gap means the distance to the caption, and adds to the quiet zone
rather than eating into it. Each stock preset carries the gap that suits it.
Position had one pair of controls and they moved the label box on the
stock. That is the fix for a printer whose origin is off, and it is not the
fix for a code sitting in the wrong place on a label - but it was the only
lever there, so it got used for both. The label div is now the media and
holds still; everything printed sits in a content wrapper that Align,
Vertical and Content X/Y move within it. The old pair kept its behaviour
and is labelled Media X/Y.
A badge card has two sides and the generator only ever emitted one page per
card. The back can now carry the same code again, a fixed block of text,
its own per-row content, or nothing. Page order is a choice because the two
kinds of printer want opposite things: interleaved for a duplex card
printer, which takes pages two at a time, and grouped for a single-sided
one whose stack gets flipped and reloaded. A row that leaves its back
column empty still gets a blank back page - a page count that varies per
row shifts every later back onto the wrong front, which prints a box of
perfectly readable cards that are all wrong.
CSV parsing and page building moved to plugins/tools/frontend/labelPages.js
(committed in 875fde9), where the column contract and both page orders are
covered by tests rather than by looking at the preview.
Printers become a property of the bay, and the container stops throwing away the
site's own files every time it is updated.
Printer assignment is now end to end. The assignment belongs to the MACHINE and
reaches whichever PC controls it, so a reimaged or swapped bay comes back with
its printers and nothing had to be saved off the old box. One picker serves both
forms rather than two implementations of the same override. A relationship type
can declare itself singular, so setting a second default REPLACES the first
instead of silently losing to the older row. Alongside the assigned half there is
now an observed half: a bay reports what it actually has, kept strictly apart
from what it is told to have, because a drifted bay's own state becoming its
desired state would make every configuration error permanent. The client script
corrects a drifted queue in place rather than only installing a missing one, and
a driver rollout can be spread across waves so 300 bays do not pull 30 GB through
one five-minute window.
DOCKER SITES SHOULD READ THIS PARAGRAPH. The compose stack never persisted the
instance directory, so `docker compose build api && up -d api` - the update path
the docs themselves gave - discarded plugins.json and every upload with it. It is
a volume now, and DEPLOY.md carries the one-time rescue for a stack that predates
it. The image also could not be built at all: the frontend stage never copied the
plugin staging script its own prebuild hook runs, so every build since that
script landed failed. Air-gapped sites need a fresh offline bundle, because the
stack moves to MySQL 8.4 LTS and an existing tarball carries only the 8.0 image.
The Windows installer already bundled MySQL 8.4, so this closes a gap between the
two halves rather than moving anyone.
Adds a topology migration guide: IIS to Docker, Docker to a new host, and back.
The data moves cleanly; what costs time is that the server address is baked into
GE-Enforce manifests, the generated collector script, the printer client scripts
and printed QR codes.
1736 tests green. Contract stays at 0.20.0 - nothing under shopdb/api changed.
INSTALL-WINDOWS-IIS.md has said MySQL 8.4 LTS is standard for new installs since
8.0 reached end of life in April 2026, while both compose files and the offline
bundler still pinned 8.0. A site reading the Windows runbook and a site reading
the Docker one were being told to run different servers, and the migration page
written this week sent people onto the dead one.
Verified against a real server rather than by editing a tag: 8.4.11, core chain
plus five plugin chains applied clean, 66 tables at a single utf8mb4_unicode_ci
collation, six alembic version tables. The image's PyMySQL authenticates against
8.4's caching_sha2_password, which is what requirements.in already pins
cryptography for.
Existing servers need one thing done FIRST: 8.4 removes mysql_native_password,
so an account created on 5.6 or 5.7 must be moved to caching_sha2_password
before the upgrade or it cannot authenticate afterwards. In-place also has no
downgrade path, and 5.7 cannot reach 8.4 in one hop. For databases this size a
dump into a fresh 8.4 server is the better trade: same outage, and the old
server stays as the rollback.
Air-gapped sites need a fresh offline bundle, because the tarball carries the
MySQL image alongside the app image.
Also here, found by having it bite during that verification: the db healthcheck
pinged over the unix socket, and the entrypoint's init pass answers on the
socket while running the server with --skip-networking. The probe therefore
reported healthy DURING init, which is what `depends_on: service_healthy` gates
api and migrate on. A ping passed at 8 seconds and the next query failed because
the server was mid-restart. Probing 127.0.0.1 keeps it red until the real server
is listening.
`db_data` was a volume and the instance directory was not, so the documented
update path - `docker compose build api && up -d api` - recreated the container
and discarded everything the site had written. `plugins.json` is only the loud
part: maps, branding, model and application images, employee photos, warranty
proofs, slides, printed-part files and the Dell OAuth token all live under
instance_path too. MySQL rows survive and point at files that are gone, so the
second symptom is images 404ing rather than an error anybody sees.
Reported by an adopting site, which read it as having updated too fast. It had
not; nothing it could have done differently would have kept those files.
DEPLOY.md had been telling sites to back up `instance/` since it was written.
The template never gave them anything to back up.
The air-gap `migrate` service mounts the volume too, because
`flask plugin upgrade-all` rewrites plugins.json and that service exits
immediately after.
The image now creates instance/ ITSELF, owned by the app user. Docker seeds an
empty named volume from image content at the mountpoint, ownership included;
with no such directory in the image the mountpoint is created root-owned 0755
and the container, which runs as shopdb, cannot write into its own instance
directory. Caught by running the built image rather than by reading it: the
volume mounted clean and `touch` came back Permission denied. Verified fixed the
same way.
A stack that predates the volume needs its files moved across ONCE, while the
old container still exists - the volume is seeded from image content, and the
image ships instance/ empty, so it comes up empty rather than inheriting the old
container's writable layer. DEPLOY.md carries the procedure, including the chown
after `docker compose cp`, which writes files under the copying user's numeric
uid rather than the app user's.
Also here, found while checking what an upgrade actually runs: the connected
update steps ran `flask db upgrade` and stopped. Per-plugin Alembic chains
(ADR-008) are not part of that, so a connected site taking an image with a
bumped plugin migration ran the core chain and silently skipped every plugin
chain. The air-gap stack had it right all along. Both commands are in Step 9
now, plus a `db current` check against `db heads`.
The last of the buildings-and-levels bugs, and the shop-floor clients brought
into the product.
Anyone on 0.11.0 through 0.11.2 should take this. Every hover mini-map in the
product reported "this asset has a position but no level" - the levelid prop
added in 0.11.0 was passed by none of its seven call sites - and the map PDF
printed markers from every floor onto one sheet, which nobody can correct once it
is carried onto the floor. The legacy import loader, still to run against
production, created markers with no level at all.
The gate that should have caught all three asked whether a FILE mentions levelid
rather than whether each position does. It now checks per occurrence.
Also: printers can be assigned to a MACHINE and reach whichever PC controls it,
so a reimaged bay reinstalls its own printers with nothing saved off the old PC;
printerdrivers can name a vendor, so two rows cover 41 of 44 printers instead of
twenty-one near-duplicates; and the collector reporter and EventSaver now live in
the repository with no site baked into either, the reporter generated per site on
request.
The client scripts were validated on Windows 11 against a live ShopDB, not only
by the suite: a bay with no rows of its own created both queues from its
machine's assignment, bound them to the right universal drivers, and set the
per-user default.
The version and the changelog are the release; the detail is in the entry.
Bug fixes for the buildings-and-levels work in 0.11.0, every one of them found by
using the feature rather than by the suite.
Anyone running 0.11.0 or 0.11.1 with more than one level should take this
release: the map drew markers from every level on whichever floor plan happened
to be showing, which is the failure ADR-017 exists to prevent, and it was in the
one component that draws the map. The viewer also had no way to choose a level,
and the editor never accepted a click at all - its handler was bound only if the
map was already a picker at mount, and the editor opens with nothing selected.
Also: a level's native size could not be set (the settings page had no height
field), the same search could return different rows because fourteen searchers
truncated without an ORDER BY, and both map pages carried a scrollbar from
subtracting the wrong page chrome from the viewport height.
No schema change, and the plugin contract stays at 0.20.0.
The version and the changelog are the release; the detail is in the entry.
A patch release. The pagination-cap fixes, and the documentation that missed the
0.11.0 installer by a few minutes.
docs/UPGRADE.md is one of the documents the Windows installer puts on the server,
and its buildings-and-levels section was committed after 0.11.0 was tagged. So
0.11.0 shipped the page an operator reads WHILE upgrading without the guidance
about that upgrade - which matters most on an air-gapped box, where there is no
other way to reach it. The installer now also ships FLOOR-MAP.md for the same
reason the Windows runbooks ship.
No application code changed on the server side and the plugin contract stays at
0.20.0.
The version and the changelog are the release; the detail is in the entry.
The floor map became a set of drawings instead of one picture, and search now
reaches what the forms have been collecting all along.
A site can hold more than one building and a building more than one level, and
every map position records which drawing its coordinates belong to. An existing
single-map site upgrades into one building and one default level carrying the
blueprint it already had, and nothing moves on screen. Landmark recalibration
moves a level's markers onto a redrawn plan, solved per axis from the landmarks
and never from the image dimensions, dry run by default, snapshotted before it
applies.
Two identifiers the UI collects were findable in almost no way and two plugins'
records in no way at all: gaugelabreference matched only measuring tools,
maintenancereference matched nothing anywhere, and USB devices and printed items
were absent from search entirely because neither is an asset. All four are
searchable now, from the global bar and from every list's own search box.
Contract 0.20.0 is additive: a plugin that writes a map position must write its
level with it.
The version and the changelog are the release; the detail is in the entry.
The map was one picture of one floor. A second floor was added, the blueprint
changed size, and machines moved, so a position now records WHICH DRAWING its
coordinates belong to.
Buildings and levels (ADR-017). Each level owns its blueprint per theme and its
own native pixel size; assets.mapx/mapy are pixels of assets.levelid, not of the
site. A position whose level is unknown renders "level unknown" and is never
drawn on the default level, because a marker on the wrong floor plan looks
entirely correct while pointing at the wrong place.
Repositioning in bulk: filter by unplaced, needs-review or level, search, place,
confirm. Landmark recalibration solves the transform PER AXIS from landmark
pairs and never from image dimensions - the canvas grew taller without
rescaling, so a dimension-derived scale would stretch Y by 1.57 and be wrong
everywhere. It defaults to a dry run, reports what would land off the drawing,
snapshots before applying, and clears mapverifiedat because a transform is a
guess awaiting review. Snapshots restore, including the level and the review
state, and a restore snapshots first so an undo is undoable.
Search: gaugelabreference was matched only for measuring tools and
maintenancereference was matched nowhere at all, for any asset type, while
Settings happily offers both identifiers on machines and PCs. A tag an operator
is told to record has to be findable or it is a write-only field. USB devices
and printed items were unreachable from search entirely - neither is an asset,
so the generic asset search could not see them and no searcher existed; they
now match on serial, asset tag, label, bin code and gage-lab tag, honouring
isactive, with Settings toggles and result labels to match.
The retired-application rule was half a rule: GET /api/knowledgebase hid
articles whose topic application is retired while global search still returned
them and printed the retired application as the subject. A filter is only real
if every path that reaches the row applies it.
Contract to 0.20.0 (additive): Asset gained levelid and mapverifiedat, Location
gained levelid, and resolve_asset_position returns the levelid belonging to
whichever source supplied the coordinates. The five plugins that write a map
position are re-pinned. The install-list text format gained levelid as a NINTH
field, appended, because the shipped Pascal installer reads fields 0-7 by index.
That installer still compiles in one drawing's dimensions and bundles one
blueprint, so its map is accurate for the default level only; /api/maplevels is
deliberately unauthenticated so it can read both at runtime once rebuilt.
Recorded in PRINTER-INSTALLER.md section 6 along with the other known gaps.
Migration 7d33 converts an existing single-map site into one building and one
default level carrying the old map_* settings, then assigns every placed asset
and location to it. Nothing moves on screen. Old settings rows are kept so a
rollback still finds them. Verified end to end on MySQL 5.6 from a
production-shaped database.
A privilege-escalation fix in the Windows installer, the multi-site portability
work, and a documentation and API surface that a second site can rely on.
The installer created C:\shopdb-flask, C:\Python314 and C:\MySQL84 without
breaking inheritance from the drive root, whose default DACL grants
Authenticated Users an inherit-only Modify. Two files inside those roots are
executed by someone else - shopdb-admin.ps1 self-elevates, and instance
config.py is loaded unconditionally by the app - so any logged-on user could
replace either and wait. Verified fixed as SYSTEM in the Windows 11 VM against
the shipped functions.
Contract 0.19.0 is breaking: get_dashboard_widgets returns data and shape, not a
component name. The change itself shipped earlier without a bump, with the
contract docs still teaching the dead shape; both are corrected.
The version and the changelog are the release; the detail is in the entry.
The export gate now carries the site patterns, and three kinds of file tripped
it - two legitimately, one by construction.
Two test files held real internal subnets as fixtures. They are documentation
ranges now, which test the same logic and disclose nothing.
The project-map generator and a changelog entry named a file that is excluded
from publication, so a public reader was pointed at something they cannot see.
Both now describe what happened without naming it.
And the naming script has to CONTAIN the site patterns in order to grep for
them, so written literally the rule's own definition fails the gate that
enforces it. The patterns are assembled from fragments, the same trick the docs
publishability test already uses for the same reason. Verified the hard way: a
planted literal is still caught, so the fragmentation did not quietly turn the
rule into one that matches nothing - which is the obvious way for this fix to
have gone wrong.
The asset reporter and EventSaver are both already built to be repointed - the
server URL, the API key and the targeting are parameters, an ini file and
manifest targeting, not code. Nothing said so, so the question "can another shop
use this" had no answer that did not involve reading PowerShell.
Worked examples for all three deployment paths, because sites have different
management planes and the choice is not ours to make: Intune (a remediation for
the reporter, a Win32 app for the screensaver, plus a Machine Configuration/DSC
form for estates already governed that way), a GE-Enforce manifest entry, and
manual installation for a pilot or a single bay.
The two traps are written down rather than left to be discovered. EventSaver
falls back to a path compiled into the binary when its ini is missing, and that
path belongs to the reference site - a missing ini is not a neutral default. And
a config enforced by hash reverts a hand edit on the next cycle, which is the
feature working correctly and reads exactly like a bug.
Also notes the reporter's -ApiUrl default still points at the reference site, so
every example passes it explicitly until that is fixed.
CLAUDE.md is read at the start of every session and claimed contract 0.16.0 and
1159 tests while the code was at 0.18.0 and 1567, along with a plugin count and
a chain head that were both wrong. Hand-written facts about a moving codebase
are wrong within a fortnight, and a reader who cannot tell which lines are stale
has to re-derive all of them.
So they are derived. scripts/gen_project_map.py reads the versions, the plugin
inventory, every Alembic chain head, the ADR index with status and the size of
the codebase out of the code, and --check fails a build where the committed map
no longer matches. CLAUDE.md now points at it, leads with the multi-site rule,
and lists the gates to run instead of restating the conventions they enforce.
The changelog's Unreleased section covered 8 of the 46 commits since 0.9.0 and
had no Changed, Fixed or Security sections at all. It now carries the whole
fortnight, including both contract bumps - which had never been recorded even
though ADR-002 makes contract versions their own series.
The report answers a purchasing question, and it was answering it in seven
columns, two tables and a rowspan. What someone actually needs from it is a
short list of what to buy.
So it opens with that list, grouped by part number with a quantity. Two
cartridges of the same part in different printers is a quantity of two, which
is the number an order needs and the one a per-printer table made the reader
count by hand. It covers what is empty plus what goes within a fortnight -
ordering only what is already empty means running empty. There is a copy
button, because it ends up pasted into a mail.
Below it the cartridges sit in urgency bands rather than in one long list
sorted by a number. The question is which pile a thing is in, and a pile that
is empty is worth seeing as empty. Everything past "empty" starts collapsed;
the order list above already covers the same ground in a tenth of the height.
The row is a cartridge now, not a printer, so it can carry its own part number,
its own level bar and its own countdown. Nesting supplies under a printer meant
opening a printer to find out whether anything on it needed doing.
Cartridges with no part mapped are counted on a single line rather than given
one each. They cannot be dropped, since that would quietly shorten the order,
and they cannot be ordered from here either - the job they represent is
mapping them, which is one job however many there are.
Bands and the order horizon are decided server-side, next to the arithmetic
that produces them, so a heading cannot disagree with what got added to the
list.
Checked against a fleet of 43 dev printers with real part mappings, driven by
a stub Zabbix - live Zabbix is not reachable from the dev box.
Four defects stacked into one nonsense report: cartridges at 20% claiming four
days, cartridges at 1% claiming weeks.
The root cause is a Zabbix API detail. `limit` caps the whole result set rather
than each item, and the query sorted ascending, so the cap kept the OLDEST rows
in the window. A four-cartridge printer polled every five minutes writes over
100k readings in 90 days; the forecast was fitted to the first few days of that
and nothing since. Every rate was real and every rate described a cartridge
thrown away three months ago. Nothing in the output looks wrong, which is why
it needed pinning in a test rather than a comment.
A 90-day burn rate does not need every individual poll, so a long window now
reads hourly trends - the table meant for this, a tenth of the rows, and kept
longer. Raw history serves short windows and any item a site keeps no trends
for. Both are fetched newest-first with the budget scaled per item.
Second, the countdown was computed from the last stored reading while the level
displayed was the live one, so the two could disagree by a whole cartridge. The
live level is now what the countdown divides. A live level far above the stored
run means it was swapped since the last reading, and that is reported as a
replacement rather than as a collapse in the burn rate.
Third, at or below 5% a cartridge reads as empty rather than as a slow drain.
At 1% losing a tenth of a point a day the arithmetic says ten days. The printer
is out of toner, and it is the first thing to order.
Fourth, the days-left column spanned the printer's rows, so the printer's
soonest figure was printed beside every supply it had. That alone accounts for
the shape of both complaints: a healthy cartridge wearing its neighbour's
deadline, and an empty one wearing a number that belonged to nothing on its row.
Also fixes float-typed supplies vanishing from any printer that also had an
integer-typed one - they live in different history tables and the fetch stopped
at whichever answered first.
Not verified against live data: Zabbix is not reachable from the dev box.
Ten routes shipped over the last few commits without reaching the inventory,
which is the file everything else is generated from - openapi.json, the /api/docs
browser, and the per-site build. An endpoint absent from it is invisible to
anyone integrating against the API even though it answers requests.
The auth notes matter more than the paths. API-REFERENCE tells a deployment
reviewer that essentially every GET is optional-auth; two of these are not, and
an exception buried in a table of 372 operations is one nobody reads. The
installer download and the warranty proof are called out with why: one is
licensed vendor software, the other carries pricing and a service tag. The
application image is listed with the fully public endpoints, since tiles render
before login.
lastseenat already recorded it and the API already returned it; nothing
displayed it, so from the UI a healthy machine still looked abandoned - one
revision from last spring and no sign anything had looked at it since.
The history page gains a Last verified column beside Captured, and the asset
panel a Verified field. Only the CURRENT revision carries one: an older
revision was superseded, so saying it was verified today would be false - what
was verified is the configuration the PC holds now.
A current revision with no check yet says "not yet checked" rather than showing
a blank or borrowing the captured date. That state is real and temporary: the
column is new, so every chain reports it until its PC next posts.
Three plugins still declared widgets naming Vue components nobody wrote.
Converting them honestly meant three different answers, not one.
notifications gets a real card: the active notifications themselves, not a
count. "4 active" tells an admin nothing; knowing WHICH message the shop is
looking at is the point, and it is how a stale one gets noticed and taken down.
machines gets machines out of service - anything not In Use, excluding
Inventory, because a spare on a shelf is stock rather than a problem. Someone is
supposed to be chasing each of those and today they are visible only to whoever
thinks to filter the list by status.
network gets NOTHING, and its declaration is deleted rather than converted.
Network devices carry no live status - no polling, no reachability check,
nothing that can be wrong - so the only possible card is a count of how many
exist, which is precisely the always-true number this dashboard exists to get
away from. A comment records that, so the next person does not re-add it. If
reachability is ever collected, that is the card.
Also adds a contract test over every declared card: no component names, a valid
renderer and severity, and - the one that matters - the endpoint must be a REAL
route. A declaration pointing at a route nobody wrote is exactly how the old
widgets rotted unnoticed for months, and now it fails the build instead.
Wave one complete. Three cards, no new data and no migrations.
Printer supplies reuses the existing low-supplies query and its five-minute
cache; a Zabbix round-trip per printer on every dashboard load would make this
the slowest page in the app. One row per printer listing every depleted
cartridge, criticals first - a row per cartridge would report one printer three
times and read as three problems, and showing only the worst class would hide a
low cartridge behind a critical one on the same machine when whoever walks out
there wants to carry both.
While there: the low-supplies REPORT itself was including healthy cartridges. A
printer with one empty black and three full colour ones listed all four, so the
reader had to find the problem inside the row. It now lists only what needs
replacing, and the test that asserted the old behaviour now asserts the new.
Expiring warranties keeps already-expired entries on the list rather than
dropping them the day they lapse, which is how they get missed. Horizon is
warranty_expiringdays, default 90, because that suits a site budgeting
quarterly and nobody else.
Mis-numbered bays promotes check-shared-machines out of a CLI command nobody
will remember to run - it found seven bays that had been wrong for weeks. It
reports only numbers with NO child assets, so part markers legitimately sharing
an operation stay silent: that distinction is the whole card, and without it it
would list correct data beside faults and be ignored.
Printers also loses its dead component-named widget; notifications, network and
machines still have theirs.
The stale-backup card could not be built as designed, and the reason is more
important than the card. Dedup means an unchanged configuration writes no
revision, so collectedat moves only on a CHANGE. A machine stable for six
months has a six-month-old newest revision and is perfectly healthy. Keying a
staleness card on revision age would have flagged most of the fleet - exactly
the noise that makes a board worth ignoring.
Underneath that: ShopDB could not distinguish those cases at all. On a no-op
the server returned "unchanged" and wrote nothing, so "we checked yesterday and
it matched" was discarded. That fact is the one thing a backup system must be
able to prove, and the only record of it was a line in a log file on the PC.
lastseenat records the check rather than the change. Touched on every matching
post including the no-op; set on creation, since a new revision has by
definition just been seen; backfilled from collectedat or createdat so existing
rows start from the last moment the config can be PROVEN current, rather than
from now - claiming a check that never happened would be worse than silence.
The card keys on it, one row per CHAIN rather than per asset: a machine with
two part markers can have one still reporting while the other stopped, and a
per-asset view would report the machine as fine. It stays deliberately silent
about assets never backed up, because whether one SHOULD be is a question only
the manifest can answer, and guessing would list a hundred healthy machines.
The rule lives in services/staleness.py rather than the route, so it is
testable without an auth layer in the way - the same split retention.py uses.
Threshold is backups_staledays, default 3, and 0 disables the card.
Product version to 0.9.0, frontend in lock-step, Unreleased notes moved into a
dated section per ADR-007. The plugin contract stays at 0.16.0: it moved after
v0.8.1 and is already recorded in this release's notes, and nothing since
touched the contract surface.
A minor rather than a patch: collector behaviour changed in ways an integrator
must know about. A reported machine number no longer becomes the PC's asset
number, it builds a controls link instead; a second PC claiming a machine is
treated as a claim rather than a handover; and a backup revision chain is now
per source PC rather than per asset.
A PC that drives a device which is its own asset had been implemented twice.
METROLOGY_TOOL_MAP covered CMM, Keyence, Genspect and wax-trace, minting a
measuring_tool. A separate path keyed on one hardcoded pc-type minted a Part
Marker machine and filed it under its operation. Both create a device, link the
PC with controls, and archive that link when the PC is re-imaged: one mechanism
with different nouns, written out twice because the second case arrived later.
That is the same trap as the site literals in ADR-015 - a pattern implemented
per instance rather than declared - and it has a known next occurrence. Part
markers already share operation numbers, and any site with two marking lasers
or two wax-trace units on one number needs identical treatment.
One SUBORDINATE_DEVICE_MAP now declares asset type, type name, naming suffix,
whether the device files partof the operation, and the relationship label. The
labels are unchanged per case on purpose: those values are in the production
database and only rows carrying them are archived by a collector push. A site
overrides or adds an entry through subordinatedevice_<pctype> settings, per
ADR-015, so the next case needs no code. A malformed override falls back to the
default rather than failing the push, because a bad setting must not stop a bay
reporting its inventory.
metrology_tool_for stays as a shim over the same map: filters.py and the older
tests read it, and unifying must not change what it returns. A test pins that.
Also adds flask relationships check-shared-machines, which finds the next 0615
rather than waiting for someone to notice duplicate backups. Several devices
legitimately sharing a number and two PCs mis-numbered at imaging look the same
from outside; the difference is whether child assets exist, so that is what it
reports. Read-only.
Backup-NtlarsSettings reads backups_intervalhours from /api/settings/public,
because it runs before it holds any credential, and its Get-IntervalHours falls
back to 24 on any failure. The plugin never declared the key public, so the
endpoint did not return it, the fallback fired on every PC, and the setting
looked configurable in the UI while changing nothing. The fleet log shows the
symptom plainly: "Throttled: last attempt under 24h ago", every cycle,
regardless of what the setting said.
Declared public. A collection cadence is not a secret. backups_shareroot stays
private - it is internal topology - and the test asserts both directions so a
later edit cannot quietly widen it.
Same defect as the 3D parts kiosk label prefix already in this changelog: a
logged-out reader against an allowlist its key was not on. Worth noticing that
the pattern has now bitten twice.
Several Telesis markers serve one operation number - 0613, 0615 and WJPRT each
have more than one - so treating the operation as the marker collapsed separate
devices into a single record. Their configurations differ by COM port, so in
the backup history they overwrote each other, and no question about an
individual marker could be asked at all: how many there are, which port one is
on, which one failed.
There is one marker per PC, which makes the PC the marker's identity, so the
collector can mint the marker the same way it already mints a CMM or a Keyence
unit for a metrology PC. A marker PC now gets a Part Marker machine asset, the
PC controls it, and the marker is partof the operation whose number the PC
reports. An operation holds any number of markers.
A marker PC therefore does not claim the operation directly. controls
propagates through partof, which reference-data already seeds, so control of
the operation still follows from controlling its marker - without two markers
contesting a link only one of them can hold.
Backups from a marker PC resolve to the marker rather than the operation, and
fall back to the machine number whenever the marker cannot be resolved: no
hostname on the payload, a lean build without the computers or machines plugin,
or a marker PC that has not reported to the computers collector yet. Filing
under the operation is the old behaviour and beats rejecting a backup.
Moving a marker to another operation archives the old membership rather than
deleting it, so where a marker used to live stays answerable.
Dedup compared a posted config against the latest revision for the ASSET,
which is only correct when a machine number means one PC. Several PCs share one
here: the part markers on 0613, 0615 and WJPRT are separate devices, differing
by COM port, filed under one machine number. Each marker's post therefore
differed from whichever marker had posted last, nothing ever deduped, and the
table grew by one row per PC per collection cycle.
A chain is now (asset, kind, source hostname). An unchanged config is a no-op
again, and each PC keeps its own history against the machine. NULL sources -
rows written before the column was populated, and hand-loaded ones - form their
own chain via IS NULL; `column == None` never matches in SQL, so without that
those rows would have re-posted forever.
Two consumers assumed the old key and are fixed with it. Retention pruned per
asset, so a busy marker's revisions could evict a quiet marker's only backup;
it now prunes each chain separately, protecting the newest and oldest of each.
The revision diff compared against the previous revision on the machine, which
across two markers reported one device's COM port as a change on the other; it
now compares within the source's own chain.
scripts/collapse_duplicate_backup_revisions.py cleans up what the old rule
wrote. It removes only a revision whose hash repeats the one before it in the
same chain - rows the fixed code would never have written - and keeps every
genuine change, every chain's newest and oldest, and every source. Dry run by
default. Its --report mode explains what grew each chain, which separates a
legitimately shared machine number from two PCs wrongly carrying the same one,
and from a value inside the config that changes on its own.
Treating "another PC is linked to this machine" as proof of replacement was
wrong. A PC imaged for machine 3010 carries that number from the bench, before
it has replaced anything, and several PCs sharing one machine number is a
normal state at this site: the part markers do it. Both PCs then reported on
their own schedules, each report moved the link and raised an alert, and the
pair traded the machine back and forth for as long as both were alive.
The PC holding a machine now keeps it while it is still alive. Alive means it
has reported within MACHINE_CLAIM_QUIET_HOURS and its asset is still In Use. A
challenger is recorded as a dormant link instead, which doubles as the marker
saying the claim has already been announced, so a PC sitting on a bench does
not alert on every collector cycle.
The handover still happens on its own once the old PC has been quiet for a day,
which is what a PC pulled off a machine does. Moving the old PC off In Use -
Retired, Inventory, In Repair - hands the machine over on the next report,
which gives IT a one-step way to force a swap the moment it happens rather than
waiting out the window. A day is long enough that a PC switched off overnight,
or one behind a network outage, never loses its bay to a spare.
Alerts for both cases are gated on a new computers_machinelink_alerts setting
and ship OFF. Several part markers legitimately share a machine number here, so
the alerts would fire on correct data. Links, warnings in the collector
response, and archived history are unaffected; only the sending is gated.
Also: the alert goes through send_alert rather than resolving recipients by
hand, which had missed the SMTP_ALERT_RECIPIENTS environment fallback, so a
site configuring SMTP by environment would have got the webhook and no email.
