unbounded repetition the match was quadratic in the subject length: on a run
of scheme-legal characters the engine restarted at every offset and consumed
to the end before failing to find "://". ffmpeg echoes the configured camera
URL into its stderr and the whole blob reaches the pattern before any
truncation, so the subject length is attacker-influenced.
The parametrize list feeds "0.0.0.0" to TasmotaService._validate_ip and
asserts it is refused. B104 matches the literal wherever it occurs and
cannot distinguish a rejection fixture from a bind address.
Split the list across lines so the token carries its own nosec with the
reason; the single-line form was 117 chars against a 120 limit.
on_printer_status_change builds reconcile_stale_active_prints(...) as a
call argument, so the coroutine is constructed even when the spawn helper
is mocked out. A bare MagicMock retained it in call_args and it finalised
unawaited during a later test's GC, surfacing as a
PytestUnraisableExceptionWarning attributed to test_printer_sensor_history.
Patch spawn_background_task with a side_effect that closes the coroutine,
and correct the _state() docstring, which claimed state="IDLE" kept the
reconcile-edge branch quiescent when it does the opposite.
The scheduler only writes waiting_reason on the model-based assignment
path, so a job pinned to a specific printer sits behind a running print
with no marker at all. Every such job rendered an identical "starts now"
ETA that was wrong by the length of everything ahead of it.
Decide eligibility on the page instead: an item gets an ETA only when its
printer is idle and it is the item the scheduler would dispatch next,
following the same ordering the scheduler uses. Staged and future-
scheduled items do not block the item behind them, matching the
scheduler, and items conditional on a previous print are excluded.
The value also froze at first render, since react-query's structural
sharing keeps the queue reference stable and nothing re-rendered the row.
formatETA now accepts a base instant and the page drives it from a 30s
clock shared by every visible row.
Retire the borrowed printers.estimatedCompletion tooltip for a queue key
that says what the number means, translated into all 13 locales.
A Kubernetes Secret written as a block scalar carries a trailing newline, and
the schema bounds the four required variables by max_length only, so an
unstripped issuer_url was stored and enabled and then raised httpx.InvalidURL
on the first click of the SSO button -- the authorize-time failure the
all-or-nothing rule exists to prevent. Whitespace-only values got through the
same way, contradicting the reader's own "an empty required var counts as
unset". The optional variables have always treated blank as unset; the
required ones now do too.
Also registers BAMBUDDY_LOCAL_LOGIN (#1589) in the typo guard, which logged
"possible typo" for it on every boot while listing every BAMBUDDY_OIDC_*
variable as legitimate.
Promoting env_bool to strict rejection made BAMBUDDY_LOCAL_LOGIN=on raise
EnvOIDCConfigError uncaught on the login/forgot-password path -- a 500 on
the exact recovery endpoint the bypass exists to keep open. env_bool gains
a strict flag (default True for the startup OIDC reader); the local-login
caller opts out so an unrecognized value falls back to "off" instead.

_env_bool returned the default for anything outside {true,1,yes}, so
BAMBUDDY_OIDC_REQUIRE_EMAIL_VERIFIED=on silently read as OFF and
BAMBUDDY_OIDC_ENABLED=on silently disabled the provider -- the exact
opposite of what .env.example claimed. Unrecognized values now raise
EnvOIDCConfigError, caught in _apply_env_oidc_provider the same way a
bad DEFAULT_GROUP or a ValidationError already is: logged and left
running, never released on a typo.
Also promotes _env_bool to env_bool now that it has a call site in
auth.py, and corrects the boolean-parsing sentence in .env.example.
BAMBUDDY_OIDC_SCOPES, _EMAIL_CLAIM and _ICON_URL fell back to their
default only when the key was absent, so `BAMBUDDY_OIDC_ICON_URL=` in
a compose file (as .env.example ships it, commented) reached the
schema validator as an empty string and got the whole provider
refused. default_group already treated blank as unset; these three
now follow the same rule.
While the Settings page was mounted it held its own copy of every
setting and synced it from the server exactly once, on first load
(:887-900). A debounced effect then diffed the live ['settings']
cache against that copy and PUT all 77 keys it manages on any
difference, with no way to tell a user edit from a value that had
changed on the server. Anything written server-side while the page
sat open was silently reverted ~500ms later (#2716, reporter
@jmoore-skild).
No interaction was needed to trigger it. The query inherits a 60s
staleTime and react-query's default refetchOnWindowFocus, and ~30
other observers share the key, so a window refocus or a refetch from
any of them moved the cache and the page wrote its page-load snapshot
back over all 77 keys -- showing "Settings saved" while doing it.
The page now tracks the last server snapshot it reconciled with. A
field still equal to that baseline has not been touched since, so a
newer server value is adopted; a field the user has edited keeps
their value and is saved over the top, so the newer of the two writes
wins either way. Typing into a text field while a refetch lands stays
safe, which is what the previous behaviour was protecting -- an
in-progress edit is by definition different from the baseline.
The baseline is seeded from the raw server row rather than from the
copy the page patches a browser-detected external_url into, so that
detection still reads as a local change and is still persisted.
The payload builder and the comparison key lists are unchanged. The
diff simply measures against the baseline instead of the live cache,
so no field can silently stop saving.
Removing the adoption step was verified to reintroduce the revert,
and removing the post-save baseline advance to reintroduce a resend
loop; both are covered by frontend tests asserting on the request
bodies rather than on rendered values.
Saving a K-profile was fire-and-forget. set_kprofiles_batch published
and returned True, and the printer's extrusion_cali_set answer was
logged at DEBUG and dropped, so a write the printer refused was
reported to the user as saved (#2718, reporter @jmoore-skild).
The reason it could not simply be gated on: the answer itself was
wrong. Single-nozzle firmware returned result:"fail" with
reason:"invalid tray_id" on writes that demonstrably applied.
Measured against an X1C and an H2D over MQTT, the cause is the
tray_id:-1 Bambuddy itself put in the payload. Sending three
otherwise identical writes isolated it: tray_id:-1 fails, tray_id:0
succeeds, and cali_idx:-1 is accepted either way, so only that one
field is at fault. The H2D ignores the value entirely; the X1C
validates it, complains, and applies the write anyway. BambuStudio
always sends a real tray_id and defaults it to 0 for a manually
entered profile.
With tray_id:0 the acknowledgement is honest, and the printer echoes
back the sequence_id we sent -- confirmed for extrusion_cali_get,
_set and _del on both printer classes -- so it can be matched to the
write that caused it. Writes now return their sequence_id and the
routes await the verdict, turning a real failure into an error that
carries the printer's own reason. A printer that stays silent is
still treated as success: no answer is not evidence of refusal, and
firmware that never answers must not turn every save into an error.
Raises the ack to INFO. It sat at DEBUG, so the one line that
explains a failed save was absent from every support bundle -- the
same reasoning that put ams_filament_drying at INFO for #1447.
Also fixes extrusion_cali_set building its payload from
str(self._sequence_id) without incrementing first, reusing the
previous command's id. Harmless while nothing correlated on it,
fatal now that the write path does.
Adds supports_nozzle_flow_type() for the Standard / High Flow choice,
which the K-Profiles UI previously showed as "Not reported by
printer" -- not a value anyone can save. Most printers omit the
nozzle identity from their calibration table entirely, and the slicer
treats that as Standard rather than unknown; Bambuddy now does the
same and keeps the choice editable. The field is hidden only where
the model ships a single nozzle variant, using the slicer's own rule
(len(nozzle_volume) // len(nozzle_diameter) > 1 over the machine
preset) evaluated across every bundled Bambu profile. That puts only
A1, A1 Mini and A2L on the hidden side -- it is not the single-
versus-dual-nozzle split, since P1P, P1S, P2S, X1, X1C, X1E and H2S
are all single-nozzle and all carry two variants. Editing a profile
also no longer writes back an empty nozzle_id.
Wiki records that on printers which omit the field the chosen flow
type is discarded by the firmware and reads back as Standard, in
Bambu Studio as well, so it does not get filed as a bug again.
Add K-Profile built its Filament dropdown from the profiles already on
the printer, so on a printer with none the field was empty, required
and unsatisfiable (#2719, reporter @jmoore-skild). The modal's own
hint described the dead end: create the profile in Bambu Studio first.
The dropdown now uses the app-wide lookup order -- local imported,
Orca Cloud, Bambu Cloud, hardcoded built-in table -- same as the AMS
slot picker and the SliceModal tier groups. The built-in table is
compiled into the backend, so the list can never be empty: a new
printer with no cloud account and nothing imported still gets a first
profile.
Not fixed the way the report suggested. Seeding from
/printers/available-filaments would have offered only what happens to
be in an AMS right now, which on the reported printer is nothing; its
tray_info_idx is empty or a cloud user preset rather than a filament
id; it aggregates across every printer of the same model; and it is
gated on QUEUE_CREATE, which the K-Profiles page does not hold.
The printer indexes its calibration table by filament_id, so the
picked preset is reduced to one before anything is sent. Built-in
entries and Bambu official cloud presets carry one; a cloud user
preset needs its detail fetched (never base_id -- that collapses a
custom preset onto its inherited generic, #1053); imported and Orca
presets have no Bambu id at all and take the closest generic for
their material, via the same table the AMS slot configure flow uses
so the two agree. A filament that resolves to nothing is refused with
a named error rather than written under a wrong id.
Collapses duplicates from two separate causes. A cloud account
carries one copy of each filament per printer model, and with the
"@BBL <model>" suffix stripped for display those rows are
indistinguishable -- deduped within each tier by resolved filament id,
by display name for user presets that have none. Cloud setting_ids
also carry a "_NN" variant suffix, so the built-in tier's
already-covered check never matched and listed the same filament
again; the bare id is now recorded alongside.
Groups the options by source with an optgroup per tier, styled in
index.css: browsers render optgroup labels small, grey and italic,
which buries the one thing distinguishing a "Bambu PLA Basic" you
imported from the one the built-in table ships.
Drops the second getKProfiles(printer, "0.4") query that existed only
to seed the old dropdown. It ran concurrently with the main fetch
whenever a non-0.4mm nozzle was selected -- the two-requests-in-flight
case that made K-profile fetches time out.
---
fix(ui): cancel a dialog's deferred close when it unmounts
The AMS slot configure and K-Profile dialogs hold a success state
briefly and then close themselves -- 1.5s to 4s after the command
goes out, so the printer has time to process it before the list
refetches. Each did that with a bare setTimeout closing over setState
and the parent's onClose, and nothing cancelled it.
The timer therefore ran whether or not the dialog was still there.
Dismissing it inside that window, or the printer card re-rendering
underneath it, left a pending close that fired later and dismissed
whatever dialog was open by then. It also threw outright when the
surrounding environment was gone first: a test tearing down its DOM
before the 1.5s elapsed produced "ReferenceError: window is not
defined" out of react-dom's resolveUpdatePriority, reported as an
unhandled error against a suite that otherwise passed.
Routes all five through a useCancellableTimeout hook -- two in
ConfigureAmsSlotModal, three in KProfileModal, the latter with the
longest windows and so the widest exposure. Scheduling replaces any
pending timer and unmounting clears it.
Every K-profile came back as 0.4mm on printers running any other
nozzle (#1748, reporters @Liquidmasl and @jmoore-skild). The printer
puts nozzle_diameter on the extrusion_cali_get envelope only; the
per-filament entries carry setting_id, filament_id, name, k_value,
n_coef and cali_idx, and nothing else. The parser read the field per
entry with a hardcoded "0.4" fallback, so the fallback fired on every
profile of every response. The envelope value was already in scope,
read into response_nozzle and used only to match the request.
This never reproduced on H2D because that firmware does include the
field per entry. Both construction sites are in the same handler, so
the code path is shared; what differs is the payload, and every
single-nozzle model omits it.
The display was the least of it. Editing is delete-and-re-add on
single-nozzle printers, and the dialog rebuilt nozzle_id and
nozzle_diameter from its own greyed-out selects, so saving an
untouched 0.6mm profile rewrote it on the printer as HH00-0.4.
Deleting aimed extrusion_cali_del at the wrong nozzle the same way.
Both now pass through what the printer reported. The cali_idx cascade
in inventory.py, spoolman_inventory.py and spoolman.py matches on
nozzle_diameter, so on a 0.6 or 0.8 nozzle it never found the
printer-side entry and the assignment silently failed to stick --
that is the "cannot auto-map a K-profile" half of the report, fixed
at the source without touching those three call sites.
nozzle_id has no source in the payload at all, and state.nozzles
carries material (hardened_steel), not flow, so it cannot honestly
produce HH/HS. Rather than keep inventing one, the UI now says the
printer did not report it: the card shows the diameter alone, the
dialog shows "Not reported by printer", and the High Flow / Standard
filter is hidden instead of being offered as a control that can only
ever empty the list. Import stops stamping HH00 on profiles whose
source reported none.
Also correlates K-profile requests by sequence_id. Responses were
matched by nozzle diameter through a single shared expectation slot,
so a second request overwrote the first's and the first's valid
answer was discarded as a mismatch -- the "Failed to get K-profiles
after 3 attempts" in the same logs, with the printer having answered
correctly both times. Pending state is now one entry per request,
keyed by the id we already send, with the nozzle match kept as a
fallback for firmware that does not echo it back.
Fixes the flow-type select naming a new profile with the opposite
label, which contradicted the identical expression 44 lines above it.
Enabling Cloud Profiles for a Git backup produced nothing, and said it had
worked. Two independent faults, either one sufficient.
The collector looked for a "setting" list. The Bambu Cloud listing endpoint
is keyed by preset type instead, each key holding private and public arrays,
so the loop body never executed once — and the entries carry no type of
their own either, which routes/cloud.py already knew: it takes the type from
the outer key and maps Bambu's "print" to process. Two bugs on one line.
It also asked build_authenticated_cloud for the credential store used when
authentication is disabled. With auth on, tokens live on User rows, so the
collector returned at "Cloud not authenticated" before ever reaching the bad
key. Every multi-user install was collecting from zero accounts.
Neither failure surfaced. backup_metadata.json recorded the configured flag
rather than the outcome, so it claimed cloud_profiles: true on runs that
wrote nothing, and the log read "Collected cloud profiles: 0 filament, 0
printer, 0 process" at INFO — which is exactly what a successful backup of
an empty account looks like.
Cloud profiles now come from every connected account across both clouds. The
toggle predates Orca Cloud entirely, and Orca has the same three preset
types, so both are collected and grouped the same way:
cloud_profiles/bambu/user-3/{filament,printer,process}.json
cloud_profiles/orca/user-3/{filament,printer,process}.json
Accounts are keyed by Bambuddy user id, "global" when auth is off. Never by
email: a backup repository can be public, and the Bambu listing's user_id is
dropped for the same reason. Both credential stores are read on every run,
because a Settings row survives someone enabling auth later and dropping it
would silently stop backing that account up.
Bambu costs one get_setting_detail per private preset. The listing is
metadata only, and without base_id and setting the backup is a list of names
that create_setting cannot rebuild from. Public presets are skipped — Bambu's
bundled catalogue is the same hundreds of entries for everyone, always
re-downloadable, not recreatable under your account, and would rewrite the
repository on every run. Orca needs no second call; its sync-pull carries
each profile's content inline. Where the Orca route drops a profile whose
content.type it cannot map, the backup writes it to other.json instead:
silently omitting a profile because Orca added a type is the same class of
bug as this one.
Failures are contained per account and per preset, and counted rather than
swallowed. A partial backup that looks complete is how this stayed invisible.
The metadata now reports what was collected, per cloud and per account, and a
run that collects nothing while the category is enabled warns with the reason
instead of an INFO line that reads like success.
The checkbox gated on the viewer's own Bambu sign-in, which is not the same
question as whether there is anything to back up — with auth enabled the
accounts belong to individual users, and an administrator who never signed
in personally saw the category disabled with plenty in scope. It now gates
on the total across both clouds and shows the counts. That comes from its
own endpoint rather than a field on /config, since /config answers null
until the first save and would disable the toggle during the very setup it
belongs to. Counts only, never identities.
One deliberate restraint. _build_authenticated_service clears stored
credentials when a refresh is rejected, which is right for a route — the
user is on the page and can pair again — and wrong for a scheduled job.
Orca reports every rejection with one composite reason ("unknown, expired,
revoked, or already used"), so a genuine revocation cannot be told apart
from a lost token-rotation race, and acting destructively on a signal that
cannot be disambiguated is the #2562 mistake in a different cloud. It also
gains nothing: the Profiles route hits the same failure and clears it then,
with the user present. Background callers now pass clear_on_auth_failure=
False and skip the account. A successful refresh is still persisted either
way — by that point the old token is consumed, so dropping the new pair
would break a working pairing for real.
Restore is not part of this. Nothing reads cloud_profiles/* yet; the format
carries base_id/setting for Bambu and content for Orca so that it can.
Round-3 review of the "Save AMS mapping" PR.
The queue item's ams_mapping was set unconditionally, on the reasoning that
honouring the slicer's own pick is a correctness fix rather than a feature.
It is both. Storing a resolved mapping makes _ensure_ams_mapping return
early, so _compute_ams_mapping_for_printer never runs — and that function is
where prefer_lowest_filament lives, along with the AMS-filament-backup gate
that qualifies it (#1766), the inventory-remain overrides, and the per-slot
force-colour overrides. Every existing queue-mode VP pointed at a printer
would have quietly lost all of it on upgrade, without a setting to turn it
back on.
So save_ams_mapping now gates the queue item too, not just the archive
persistence. Off is exactly the old behaviour. The correctness case the PR
was written for — two spools of the same red PLA, and the slot the user
picked in the slicer thrown away — is still fixed, for anyone who asks for
it.
Force color match wins over it when both are on. Its only effect on a
fixed-printer item is the filament_overrides written onto the queue item,
and those are read inside the function a stored mapping skips, so the two
toggles sitting next to each other on the same card silently cancelled. The
dispatch now matches strictly, as asked, while the slicer's pick is still
saved onto the archive — that is what the toggle's name promises, and a
later reprint is a separate decision from this print. The queue-add fallback
applies the same rule to a request that carries force-colour overrides.
A mapping shorter than a plate's highest slot id cannot address that plate's
own slots, and _ensure_ams_mapping would have kept it anyway, since it only
rejects an all-unresolved one. Each plate now checks the length it needs and
falls back to a computed mapping if the array does not reach. Bambu Studio
sends a file-global array, so this normally never fires; it also means a
multi-plate Send All degrades safely if that ever stops being true.
The badges claimed more than they delivered. Both rendered whenever a saved
mapping existed, ignoring which printer it belonged to, while the tooltips
promised the reprint would reuse those exact spools — true only on the
printer the trays were resolved against. The queue row's flag is now
computed against that row's own printer, which is precisely when dispatch
reuses the mapping, and the archive card names the printer instead of
implying any of them will do. It hides itself when that printer no longer
exists. Retranslated in all 13 locales.
Frontend tests, which the PR had none of. The printer-scoping rule is now a
pure function rather than an inline expression, covered for the mismatched
printer, the no-printer-selected case that would otherwise compare undefined
against undefined, and malformed extra_data. The toggle's undo bookkeeping
is covered for unresolved slots, short mappings, and hand-made picks —
preserved when the toggle never wrote that slot, replaced when it did, which
is behaviour worth pinning either way.
Also reverts all three queue-mode switches when a save fails, not just the
new one; without it the card shows a setting the server rejected.
A bundle described everything except the process it runs in. So a report of
memory climbing over days until the OOM killer fires arrives with no way to
act on it: the numbers that name the mechanism only exist while it is
happening, and by the time anyone asks, the container has been restarted.
The new `process` section carries what actually separates the candidates.
Resident against virtual memory: 650MB RSS with 12.9GB VMS is address
space — thread stacks or allocator arenas — not a heap full of live data,
and that reading is the opposite of the one the reporter drew from the same
figures. Thread count and child-process count then split those two apart,
and a census of live objects by type names what a growing heap is filling
up with. Open files, sockets and uptime round it out.
Three constraints worth keeping:
The heap census is skipped above 2GB. gc.get_objects() materialises every
tracked object, so it costs most on exactly the process that can least
afford it — a bundle generated to diagnose runaway memory must not be the
allocation that tips the host over. Everything else is still collected, and
the skip is recorded with its reason rather than silently omitted.
Children are recorded by executable name only. An ffmpeg command line
carries the camera URL, and with it the camera's password.
Collection runs off the event loop and every metric is independently
best-effort. psutil raises on hardened kernels and in restricted
containers, and the bundle is how someone reports a problem in the first
place — it has to be produced even when half the numbers are unavailable.
This does not fix#2734, and nothing here should be read as having found
its cause. The bundle's own evidence contradicts both proposed causes: the
orphan janitor ran 7 times in 26 days over 725 stream-ends and killed no
orphaned ffmpeg, which is not the #776 signature; and the 5 "database is
locked" errors all fall between two OOM kills, making them a symptom of the
memory pressure rather than a source of it.
The recovery rollback after a failed commit was itself unguarded, so a
rollback that raises on a wedged connection would still take the boot
down -- the exact failure the never-raise contract exists to prevent.
Suppressed; the caller's `async with` discards the session regardless.

A heavy MakerWorld model — one Bambu Studio also takes a long time over —
failed after five minutes with "Slicer sidecar unreachable". The sidecar
was reachable the whole time and still slicing when we hung up on it.
SlicerApiService carried a hardcoded 300s timeout, passed to httpx as a
bare float so it covered connect, read, write and pool alike. On a single
long request that is not a health check, it is a cap on how long a model is
allowed to take. And because httpx.ReadTimeout subclasses RequestError,
expiry landed in the same handler as a refused connection and was reported
as an unreachable sidecar — so the reporter went and updated their sidecar
container, which was never the problem.
The information to do better was already being collected. _poll_progress
polls /slice/progress/{id} once a second alongside the blocking POST to
drive the live progress toast, so at minute five Bambuddy had fresh
evidence the slicer was working. It killed the request anyway.
So the read timeout comes off the HTTP call and the poller supervises
instead: the deadline moves forward on every progress update, and only
genuine silence ends the wait. A model that keeps reporting runs to
completion however long it takes. Connect and pool keep short timeouts —
a sidecar that will not accept a connection is unreachable and should
still say so quickly.
Only a *changed* progress payload counts as alive. The sidecar re-serves
its last snapshot on every poll, so counting repeats would leave the
watchdog unable to detect a stall at all.
The window is floored at three poll intervals: liveness can only be
observed as fast as the poller ticks, so anything shorter would expire in
the gap between two polls and fail every slice instantly.
New setting slicer_stall_timeout_minutes (Settings > Workflow > Slicer),
default 15, range 1-240, alongside the sidecar URL and gated on
use_slicer_api like its neighbours. Sidecars too old to report progress
have no liveness signal, so for those the same number bounds total elapsed
time — the old behaviour, configurable and no longer 300s flat. The
message says which case applies and where to change it.
SlicerTimeoutError is its own type and maps to 504, not 502: the sidecar
answered throughout, we stopped waiting. Connection failures keep
SlicerApiUnavailableError. The preview slice path gets the same treatment.
_local_login_env_bypass() re-inlined the same {"true", "1", "yes"} set
oidc_env._env_bool already enforces, so the typo-guard existed in two
places. oidc_env has no module-scope import of models (its model
imports are lazy inside apply_env_oidc_provider), so importing
_env_bool at module scope here is not a cycle -- confirmed by
importing backend.app.main and this module directly.
.env.example described what the required vars do but not two sharp
edges: the issuer must be a public HTTPS URL (an in-cluster
http://keycloak:8080 is silently refused), and BAMBUDDY_OIDC_NAME
matches an existing UI-created provider by name and takes it over.
A name collision with a provider that was NOT already env-managed
overwrites its issuer, client id and secret in place and locks it
behind the env-managed 409 -- but it logged the same routine "applied"
line as an ordinary re-apply, giving no signal a UI provider was just
taken over. Adoption is now a WARNING with its own wording; a routine
re-apply of an already env-managed provider keeps the INFO line.
The db.execute/db.commit calls in the upsert and release paths sat
outside the try/except that only wrapped OIDCProviderCreate, so a
commit failure at startup (connection blip, WAL lock) propagated out
of the lifespan and took the instance down -- the exact outcome this
module exists to avoid. The body now runs inside a private
_apply_env_oidc_provider(), with the public entry point catching,
logging and rolling back on any exception.
Deleting a print that belonged to a project left it on the project page as
a card with a missing thumbnail, and there was no way to remove it.
Deleting a print is a soft delete by default (#1343): the files go from
disk, the row stays so global Quick Stats keeps counting its filament,
time and cost. Every other consumer filters those rows out. The projects
module filtered none of them — the only deleted_at check in the whole file
was for LibraryFile — so a deleted print kept its project_id and kept
being listed, pointing at a thumbnail that no longer existed. The same
broken previews appeared on the overview cards, and in the timeline, where
the entry links to an archive that no longer opens. Unassigning was
impossible because the only UI that can change a print's project lives on
the Archives page, which correctly hides deleted prints: visible on the
project, unreachable from anywhere.
All eight project-scoped archive queries now filter, counts included. That
last part is a deliberate divergence from #1343, where the whole point of
the soft delete is that the contribution survives: a project is a piece of
work with a definite membership, not a lifetime total, so a project that
lists eleven prints must not claim twelve. The reasoning is recorded at
the constant so nobody later "fixes" it back.
remove_archives_from_project keeps working on hidden rows on purpose — it
is the repair path for links written before this. The BOM print_name
lookups are left alone; naming a since-deleted print is still correct.
Two more consumers had the same gap. The CSV/Excel export handed back rows
the interface says are gone — filtered at the base query, since the export
is the list you are looking at saved to a file. Per-project failure
analysis measured a failure rate against prints deleted from the project,
and disagreed with the project's own numbers; only the project-scoped
branch filters, global analysis still counts every run including orphans
as #1390 established.
Finally, the project page needed a manual reload to catch up. staleTime is
60s and the delete mutations invalidated only ['archives'], so a project
visited within the minute served its cached copy, print still there. The
project-assign mutations had the mirror-image bug: ['projects'] refreshed
the overview cards but never ['project', id]. Both now go through one
shared helper covering every project-derived key, as bare prefixes so all
cached project ids are matched.
The reporter's printer lost its session to a keep-alive timeout at 02:19
and did not come back until 11:24 — nine hours offline, with the web UI
open throughout.
check_staleness() was never going to catch it. Its first line is
`if self.state.connected and self.is_stale()`, so it only ever handles the
half-broken session that is still connected but has gone quiet. This
client had connected=False from 02:19:42 (the offline notification fired a
minute later), so every call returned immediately, and paho's own retry was
the only thing left watching. When that stopped making progress nothing
noticed.
Adds a sweep every 60s that rebuilds a client when all four hold: it is
disconnected, it had a working session before, it has been silent for five
minutes, and its MQTT port still answers. The port check is what keeps this
from becoming a nuisance — a switched-off printer is left to paho, so a
farm powering down overnight causes no client churn and no log spam. The
five-minute grace sits well past the 60s stale timeout and the 30s max
reconnect backoff, so a session recovering on its own is never interrupted.
The rebuild goes through force_reconnect_stale_session from async context,
which takes the hard-reset path: fresh client_id and paho's QoS 1 queue
dropped, so a project_file left unacked on the dead session cannot replay
into the new one and trip 0500_4003 (#1136). Rate-limited per printer,
cooldown cleared when the printer returns, and the sweep continues past a
client that throws rather than abandoning the rest of the farm. The log
line names how long the printer was gone and the last connect error, so a
session that dies repeatedly leaves a trail.
check_port gains a public alias in printer_diagnostic rather than having
the watchdog reach for the private name.
Also corrects the Developer Mode path added in the previous commit: the
wiki documents it under Settings > Network, not Settings > General. The
menu path is dropped from the translated string entirely, since it varies
by model and firmware and the wiki carries the detail.
A P1S on firmware 01.10.00.00 rejected every control command and said so:
HMS 0500-0500-0001-0007, "MQTT command verification failed". Bambuddy
received that, dropped it, and reported a healthy printer instead.
The frontend filtered it out. This code's meaning lives in attr's low half
(0500) and code's high half (0001), both of which the MMMM_EEEE short form
discards, so it collapsed to "0500_0007" — no catalog entry, no firmware
actions, and filterKnownHMSErrors drops uncatalogued action-less errors.
Catalog lookups now try full_code first, in both the description and the
filter, and errors matched that way display the four-group code the
printer's own screen shows. The remedy line is ours, not Bambu's: their
wiki says to update Studio or Handy, which does not apply to a print sent
from Bambuddy.
The developer-mode probe made it worse. It read anything that was not an
explicit refusal as confirmation, and this firmware answers the probe with
an empty result while refusing everything else — so an inference drawn
from a non-answer became "developer_mode: pass" in the support bundle of a
printer that had not accepted a command all day. The probe now has three
outcomes: explicit success enables, explicit verify-failure disables,
anything else stays unknown and the diagnostic reports skip.
The HMS is authoritative over that inference in both directions. It forces
developer_mode False when present, and clears back to unknown when the
printer stops reporting it, so enabling Developer Mode and restarting the
printer is picked up without restarting Bambuddy.
Dispatch no longer treats a refusal as a wedge. The watchdog latches the
HMS across both phases and fails the item on the first attempt naming the
code and the fix, rather than spending three uploads and 270s a lap to
arrive at a message about SD cards. The check runs after the active-state
exit in both phases, so a lingering HMS can never abort a print that is
visibly running.
Also: the "wrong or mis-cased serial number" hint no longer fires in the
moment after a reconnect. _report_messages_since_connect is reset by
_on_connect, so a reconnect landing microseconds before the staleness
check leaves it at 0 for reasons that have nothing to do with the serial —
this reporter's healthy printer was told to go check its serial 1 ms after
reconnecting.
Obico's ml_api container takes an optional ML_API_TOKEN environment variable.
With it set, ml_api/auth.py answers a bare 401 to any request whose
Authorization header isn't "Bearer <token>"; with it unset it ignores the
header entirely. Bambuddy never sent one, so pointing it at a protected server
meant deleting the token there — which the reporter had set for their Home
Assistant integration and did not want to undo.
Settings -> Failure Detection gains an ML API Token field. When it is empty no
header is sent, so an unconfigured install's request stays byte-identical to
what shipped before the setting existed.
This failed in the worst possible way, and that is the more important half of
the change. Obico decorates /p/ with token_required but leaves /hc/ open. Test
Connection pinged /hc/, so it reported success against a server that was
rejecting every real detection call, the settings looked right, and detection
silently never ran. The only symptom was a generic "ML API call failed" buried
in the status card.
So the test now proves what it claims. After health passes it probes GET /p/
with no img parameter: the auth decorator runs before the handler, so 401 means
the token was rejected and 422 ("Invalid request params") means it was
accepted. No inference work is done either way. A probe that itself errors
reports the token as unknown rather than as working — the UI says it could not
be checked instead of claiming success.
The detection loop checks for 401 before raise_for_status, so a rejected token
is reported as a rejected token, naming the setting and the environment
variable, instead of surfacing "401 Unauthorized" with no hint of what to do.
The message never contains the token; a test pins that.
The setting name carries "token", so the support bundle's keyword redactor
masks it with no new rule. Resolving "field omitted" to the saved token is the
route's job, keeping test_connection a pure outbound call with no database
access.
Second fix, same issue: support bundles misreported which printers Obico
watches. The bundle split obico_enabled_printers on commas and read an empty
value as "no printers". The settings UI writes a JSON array, and empty means
*all* printers — the default — so a working Obico setup showed obico_enabled
false against every printer in its own bundle. That is the reporter's bundle
exactly, and it points anyone reading it at the wrong subsystem. The bundle now
parses the setting the way ObicoDetectionService does, keeps a comma fallback
for any install that stored the legacy shape, and factors in the global switch.
The reporter's A1 mini has nine Flow Dynamics calibrations, all of them saved
under Generic PLA and named after the spool's colour — "Dark Brown", "Glow",
"Marble". Bambu Studio lists all nine for that slot. Configure AMS Slot offered
one: the profile already bound to the slot. After a slot reset it offered none,
leaving the slicer as the only way to assign a K value.
Two independent faults, both tripped by picking a built-in generic preset.
The filament-id match discarded Bambu's generic GFx99 ids as too broad. But the
comparison already requires both sides to carry the same id, so that exclusion
could only ever fire when the selected preset was itself the generic one —
precisely the case where the match is right. The printer keeps one calibration
table per filament id, so a slot on Generic PLA should offer everything
calibrated under Generic PLA. Equal ids now match, generic or not.
The name fallback was dead for the same presets: parsePresetName reads the
leading "Generic" in "Generic PLA" as a manufacturer, which put the matcher into
brand-gated mode and demanded the word GENERIC appear in the profile name. No
real profile has it. "Generic" is no longer treated as a brand, so profiles still
match on material when a printer reports no filament_id with its calibrations.
The one profile that did appear came from the #1689 safety net that always
surfaces the slot's active cali_idx — which is also why a reset slot, having no
active profile, showed an empty list.
Neither fix can be complete on its own, because profile names are free text and
nothing ties "Marble" to a material. The picker now also lists every remaining
profile on the printer under "Other K profiles on this printer", so a profile
that exists can always be selected. Applying one from that group needs no new
backend work: configure_ams_slot already realigns the slot's filament context to
the chosen profile's, which is what makes the cali_idx stick.
Options are keyed by name+k_value rather than the bare name, so two profiles
sharing a name are no longer indistinguishable in the select. Both render blocks
carry the change — the modal duplicates the picker for its full-screen variant.
isMatchingCalibration gets the same generic-id rule for the spool form's PA
suggester, with two guards. A new generic-id-to-material table means a PETG spool
can never claim GFL99 profiles just because both sides stored a generic id
(Nylon and PA compare as one material). And a spool that names its own brand
keeps the stricter name path, so its suggestions stay brand-specific rather than
becoming the printer's whole generic table.
The photo fired the moment layer_num reached total_layer_num. That edge is
where the printer *starts* its final layer, not where it finishes it: the
reporter's H2C capture shows it arriving at 92% with mc_remaining_time=2,
three minutes and seventeen seconds and one filament change before the print
actually ended, so the frame caught the toolhead mid-print over the model.
The trigger also latched _finish_photo_captured, which locked out both the
stage-22 and FINISH triggers for the rest of the print — so on firmware that
never reports an end-of-print filament unload (H2C and A1 Mini confirmed)
nothing could replace the bad frame.
Remove the last-layer trigger. The photo is now taken at the FINISH-state
trigger, which every model sends and which lands after the toolhead parks.
Since Bambu's end G-code drops the plate ~100mm just before that, restore the
framing before capturing: absolute G90/G1 Z to max_z_height + 10mm clearance,
settle, capture, then drop it back so the print is as reachable as the printer
left it. Absolute is the safety argument — that Z is a height the toolhead
occupied seconds earlier, so it is inside the travel limits by construction and
leaves the nozzle above the part, and it is unambiguous across model families
because Z is the nozzle-to-bed gap whether the bed moves or the toolhead does.
M211 is never touched (#2579). This is what #1145, #1397 and #1565 asked for.
The height is only trusted when two independent sources agree: the archive is
matched by the finished print's subtask_name by equality (not LIKE, so "Cube"
cannot resolve to "Cube v2"), and its layer count from the 3MF must match the
layer count the printer reported over MQTT. Matching on "most recent archive
for this printer" was not safe — on_print_complete pops the _active_prints
binding concurrently, and a print Bambuddy failed to archive would have
resolved to its predecessor. A wrong height is the one failure that could drive
the nozzle into the model.
The move is additionally skipped when the print height is unknown, when a queue
item is pending for the printer, when the printer has left FINISH, and when the
new finish_photo_restore_plate setting is off.
for every FINISH-state capture — which is what shipped the mid-print photo —
the bank is used only when the dispatcher recorded that it injected End G-code
into this print, since a SwapMod snippet may have ejected the plate. The flag is
handed over in two steps (mark_pending at dispatch, adopt at print start) so it
can never outlive its print: a job started from the slicer or SD card adopts
False rather than inheriting its predecessor's answer. Those prints also skip
the plate move outright, bank or no bank.
The bank now refreshes on mc_percent advances as well as layer changes, via a
new on_print_progress callback. Layer changes stop the instant the final layer
begins, which left the #1867 fallback frame stale by the whole length of that
layer; progress keeps ticking there and freezes before the End G-code runs, so
a swapped plate still cannot reach the bank. The last-layer throttle exemption
is dropped, since it would now fire a grab on every percent tick.
On the timelapse path the moment producer returns early, so the consumer does
the restore itself before its live-grab fallback — the documented usual outcome
on P1-series, where the video has not transferred by the time the notification
goes out and the shipped photo was of an already-dropped plate. The two waits
are now derived from the settle window and the video poll timeout rather than
hardcoded; at the old flat 75s that fallback was guaranteed to be cut off
mid-settle.
extract_max_z_height_from_3mf reads only a bounded prefix of the plate G-code,
since a sliced plate is routinely tens of megabytes and the header is ~40 lines.
It returns None for missing, unparseable, zero and negative values so callers
must treat "don't know" as such rather than defaulting.
Round-2 review fixes for #2700.
Blocking: the toggle didn't actually gate the archive write. archive.py's
promotion fired for any print_data carrying ams_mapping, but bambu_mqtt's
request-topic interception captures ams_mapping unconditionally for every
print source (slicer-direct LAN prints included). Since main.py's
real-printer auto-archive path forwards the full MQTT payload as
print_data, every archive on any install — VP or not — grew
extra_data.slicer_ams_mapping. Fixed by replacing the print_data-sniffing
with an explicit `slicer_ams_mapping` param on archive_print() that only
the VP-queue path (already gated on save_ams_mapping) ever passes.
Blocking: a saved mapping could get reused on a printer it was never
resolved against — tray IDs only mean something relative to one printer's
AMS layout. extra_data.slicer_ams_mapping is now stored as
{mapping, printer_id} instead of a bare array:
- add_to_queue's fallback only fires when the reprint's target printer_id
matches the mapping's origin printer.
- The frontend's archiveAmsMapping only surfaces (and the Mapping button
only appears) when the print modal's selected printer matches too.
- A model-based VP (target_printer_id=None, no MQTT bridge to any real
printer) never stamps a mapping in the first place — there's no live AMS
layout for the slicer to have resolved tray IDs against.
Also from review:
- Multi-plate archives now get the Mapping button too (the per-plate
FilamentMapping loop was missing archiveAmsMapping entirely).
- Added coverage for the previously-untested late-MQTT archive patch path
(_restamp_recent_queue_item), including the model-based-VP skip case.
- usingArchiveMapping now also resets on printer change, not just
plate/archive (it already worked via the printer-scoping above, but is
now an explicit dependency too).
- The Mapping button's revert (OFF) now undoes only the slots it itself
set, not every manual pick in scope — matches the comment above it.
- Added a comment on why negative-value slots (external spool) are
skipped rather than cleared when applying a saved mapping.
