- Ship tiktoken's cl100k_base inside the package and build the encoding
from it, so token counting never downloads anything.
- Default EMBEDDINGS_CACHE_DIR to <data home>/models instead of FastEmbed's
temp dir, and read tokenizer.json and repo metadata from that cache, so
a model downloads once and survives reboots.
- TTS_PROVIDER=none and STT_PROVIDER=none switch the speech features off:
the endpoints return 404, audio files fail to ingest with a clear
message, /api/config reports tts_available/stt_available, and the UI
hides the Speak and microphone buttons.
- Drop the Google Fonts Roboto import from the web UI.
- prefetch-models fills the cache the app reads; verify-offline checks the
packaged encoding.
- Docs: new Air-Gapped Deployment guide, settings and cache notes.
The connector OAuth popup posted the session token to window.opener with
a '*' target origin, so any page that opened the popup received it. An
attacker with an account on a multi-user deployment could start a flow for
their own pending session, get a victim to finish the provider consent, and
receive a token backed by the victim's Drive/SharePoint/Confluence tokens.
- Post popup results only to allowed frontend origins: the callback origin,
OIDC_FRONTEND_URL, the new CONNECTOR_ALLOWED_ORIGINS, and localhost:5173
when the callback runs on a loopback host.
- Render the success page from the callback itself so the token never
appears in a URL; callback-status ignores session_token/user_email params.
- ConnectorAuth accepts messages only from the popup it opened, on the
callback origin reported by /api/connectors/auth.
- /api/connectors/disconnect requires auth and only deletes the caller's
session.
- /api/connectors/sync and /api/remote reject session tokens the caller
does not own.
Fixes#2766
A deflate-compressed TIFF under 1 MB can declare 144 million pixels and
take 1.2 GB to convert to PNG, and Pillow only warns below 179 million.
Read the dimensions from the header and refuse images over 40 million
pixels before any pixel data is decoded. Pillow's DecompressionBombError
is now raised as DocumentParseError, so the upload fails once instead of
being retried.
- Per-user SSE cap uses per-connection leases in a sorted set instead of
a shared INCR/DECR counter with a TTL. A stream that outlived the TTL
could let the counter expire, then decrement another stream's slot or
drive the count negative. Leases refresh while a stream sends frames
and age out when a stream dies without cleanup.
- Shielded cleanup is bounded per step: stream close and on_close in
ClosingStreamingResponse, unsubscribe and close in AsyncTopic, lease
release, and the replay-budget check, so a dead Redis connection can't
hold a request or a graceful shutdown.
- Artifact downloads send an ASCII filename plus an RFC 5987 filename*
for non-ASCII names, build headers before opening the file, and close
disk handles off the event loop.
- Type hints and docstrings on the new helpers.
Move GET /api/events, the remote-device command stream and artifact
downloads from Flask to Starlette routes mounted ahead of the Flask
catch-all. On Flask each held an a2wsgi threadpool slot for as long as
its response stayed open, and because uvicorn drops writes after a
client disconnects, a closed tab never released it.
- asgi_auth: one JWT/OIDC gate for Starlette routes; the chat reconnect
reader uses it too
- ClosingStreamingResponse closes the body iterator and releases the
SSE slot or file handle even when the client leaves before the first
frame
- AsyncTopic liveness probe replaces the sync client's socket_timeout
guard against half-open pub/sub sockets
- ASYNC_REDIS_MAX_CONNECTIONS sizes the async Redis pool; every open
stream holds a connection and redis-py defaults to 100
The changelog page has been an empty stub carrying only a title, and was
hidden from the sidebar. Fill it in from the 38 pull requests merged since the
0.19.0 tag, grouped by what a reader would look for, and link the GitHub
release notes for the full per-PR list and the upgrade guide for the steps an
existing deployment has to take. Earlier releases are not backfilled.
Now that the page has content, show it in the sidebar.
Next 16.3.5 and React 19.3 in docs/, plus the transitive refresh that came
with them (mermaid 11.17, katex 0.16.47, shiki 3.23, styled-components 6.5).
Two overrides were needed:
- zod ~4.3.6. nextra 4.6.1 declares `zod: ^4.1.12` but its MDX prop
validation breaks on zod >= 4.4.0, failing prerender for every page with
"Invalid input: expected nonoptional, received undefined -> at children".
Bisected: 4.3.6 builds, 4.4.0 through 4.6.2 all fail. nextra 4.6.1 is the
latest release, so there is no upstream fix to take yet. Drop this pin
once nextra ships one.
- @xmldom/xmldom ^0.9.12. speech-rule-engine 4.1.4 (via mathjax-full ->
better-react-mathjax -> nextra) pins xmldom at exactly 0.9.10, so
`npm audit fix` cannot reach it. 0.9.12 clears 13 advisories including
GHSA-6gmq-8vp8-gcm6 (high).
Docs build passes, 48 pages indexed, 0 advisories.
The published 0.7.0 bundle carries the stranded 'use client' directive
that breaks the webpack build, so the docs deploy has been failing since
the widget landed on main. 0.7.1 ships the fix.
The lockfile pinned 0.7.0 exactly and Vercel installs from the lockfile,
so publishing the fix was not enough on its own. Raising the range to
^0.7.1 keeps a fresh install off the broken build.
The widget now ships with the docs agent's embed token, so the site works
without any environment configuration. NEXT_PUBLIC_DOCSGPT_API_KEY still
overrides it for staging.
The key is public either way. NEXT_PUBLIC_* is inlined at build time, so
it lands in the client bundle whichever way it is supplied, and every
documented DocsGPT embed carries its key in the page. Abuse is bounded by
the agent's daily request and token limits, enforced by check_usage on
the answer and stream routes.
Adds a floating "Ask the docs" bubble to every docs page. docsgpt-react
was already a dependency but nothing imported it, so no widget rendered.
The widget reads window and navigator on mount, so it is lazy-loaded
with ssr: false from a client wrapper. Its light/dark theme follows the
site toggle via next-themes, promoted here from a transitive dependency
to a declared one.
The key comes from NEXT_PUBLIC_DOCSGPT_API_KEY and the host from
NEXT_PUBLIC_DOCSGPT_API_HOST. With no key set the wrapper renders
nothing rather than falling through to the demo key the package defaults
to.
Bumping docsgpt-react to ^0.7.0 also drops a duplicate React. The old
^0.6.3 pin depended on React 18 and npm installed a nested 18.3.1 beside
the app's 19.2.8, which would have thrown an invalid hook call on first
render.
pip install docsgpt now brings the web UI with it: `docsgpt api` serves the
API and the UI on one port.
- scripts/build_frontend.sh builds the frontend into docsgpt/static
(gitignored) the way the frontend image does: .env.development as the
production baseline, and index.html loading /config.js ahead of the
bundle. hatch admits the directory into the wheel and the sdist through
`artifacts`; the package workflows run the script before `uv build` and
fail if the wheel lacks the UI. The backend image keeps ignoring it.
- docsgpt/ui.py serves the build in front of Flask: files as they are,
hashed assets immutable, Flask's own path prefixes (taken from its URL map,
so new blueprints need no registration) passed through, every other GET
rendered as index.html for the client-side router. /config.js is generated
per request with VITE_API_HOST and VITE_BASE_URL set to the page's origin,
VITE_* environment variables winning. SERVE_UI=false leaves the API alone.
- docsgpt api configures gunicorn in code (gunicorn.app.base.Application)
instead of rewriting sys.argv, so the SIGUSR2 re-exec that gunicorn uses
for zero-downtime upgrades runs the docsgpt console script again and
works; verified with a live handover.
- Docs: the pip page says the UI is included, that DOCSGPT_HOME and
DOCSGPT_ENV_FILE are process environment variables rather than .env
entries, and the settings page describes SERVE_UI.
- The image pins DOCSGPT_HOME=/app: it ships no checkout, so the data home
no longer depends on the working directory.
- api, worker, beat and migrate print the data home and env file they
resolved, so an API and a worker started from different directories show
it.
- The worker passes -Q only when asked; a bare worker consumes every
configured queue, which honours EMBEDDINGS_QUEUE and DOCUMENT_PARSE_QUEUE.
- The worker runs through celery.start and returns its exit code; click
usage errors print usage and exit 2 instead of a traceback.
- Windows: solo pool and no embedded scheduler (celery rejects -B there),
with a pointer to the new `docsgpt beat` command, which runs the
scheduler on its own.
- prefetch_models and verify_offline parse their arguments, so --help is
help rather than a model name.
- A DOCSGPT_ENV_FILE that is not a file raises instead of booting with
defaults.
- pipx: replacing the CUDA torch inside the pipx environment needs
pip's --force-reinstall (pipx inject, with or without --force, leaves a
satisfied requirement alone), and --no-deps so torch's dependencies are not
reinstalled from the PyTorch index, which carries older copies of them.
- Upgrading: the embedded Milvus and LanceDB default paths now resolve under
the checkout (or DOCSGPT_HOME) instead of the start directory; the note
names the old location and the settings to pin.
- docsgpt api binds 127.0.0.1 by default, like gunicorn and uvicorn do;
--host 0.0.0.0 exposes it. The docs say so.
- The embedded Milvus and LanceDB defaults derive from the data home, so
they follow DOCSGPT_HOME like the faiss indexes and uploads do. A checkout
run from its root and the Docker image resolve to the same paths as before.
- The docs and the pyproject comment describe the CPU torch install as two
steps (torch and torchvision from the PyTorch CPU index first, then the
docling extra): pip picks the highest version across indexes, so
--extra-index-url only yields the CPU build while that index keeps pace
with PyPI.
- AGENTS.md separates DOCSGPT_HOME (moves the data home) from
DOCSGPT_ENV_FILE (selects the .env file); the docs example uses a password
placeholder.
pip install docsgpt (extras: docling, milvus) installs the backend with a
docsgpt command: api, worker, migrate, prefetch-models, verify-offline,
reembed. Second step of the PyPI work after the package rename.
- hatchling build; the version comes from docsgpt/version.py. The wheel is
the docsgpt package with the data it reads at runtime (prompts, model
catalogs, seed config, alembic.ini and migrations) and without the
Dockerfile, the exported requirements, the sample index and local runtime
data. The application import alias stays checkout-only. uv sync installs
the package editable now that [tool.uv] package = false is gone.
- docsgpt/cli.py: api (gunicorn + BoundedDrainUvicornWorker with the image's
flags, --reload for uvicorn), worker (Celery worker with beat embedded,
--no-beat/-Q/--concurrency/--pool, solo pool on macOS), migrate, and
argument pass-through to the maintenance scripts. --help imports no app.
- docsgpt/core/paths.py: runtime data lives in a data home (DOCSGPT_HOME,
else the checkout, else cwd); DOCSGPT_ENV_FILE overrides the env file.
Settings, the dotenv load, LocalStorage and the internal upload route use
it instead of "three directories above this file", which is site-packages
for an installed package. A checkout and the Docker image behave as before.
- [project] dependencies are compatible ranges so the package installs next
to other packages; uv.lock resolves to the same versions and the exported
requirements files are unchanged.
- package-build.yml builds and checks the wheel on PRs and installs it into
a clean venv; pypi-publish.yml publishes on a published release through
trusted publishing (environment pypi), or to TestPyPI on a manual run.
- Docs: Deploying -> Install with pip. AGENTS.md notes the package.
- The post-task reclaim skip recognises the legacy application.* embed name,
so query embeds queued by the previous release do not pay a full collect.
- The Azure compose file mounts host data on /app/{indexes,inputs,vectors},
where the process actually reads and writes; it mounted /app/application/...
before the rename and /app/docsgpt/... after it, and nothing wrote to either.
- The offline image check triggers on docsgpt/requirements*.txt again;
dependabot's pip entry points at docsgpt/.
- install_hint() and its docstring name docsgpt/requirements-<extra>.txt;
the test asserts the full path.
- application/vectors/ stays ignored: the compose files still mount it.
- The durability QA script quiets the docsgpt logger tree.
- Upgrade note: the three renamed source-sync entries start their timers
from the upgrade.
- CI installs the backend requirements from docsgpt/; the old cd into
application/ silently installed nothing.
- The root .dockerignore re-admits only application/__init__.py. An upgraded
checkout may still hold gitignored application/{inputs,indexes,vectors,.env}
from the old layout, and the directory rule shipped them into the image.
- The compose files keep the host bind mounts on application/{indexes,inputs,
vectors}, so an upgrade does not start with empty data. The move comes with
the packaging work, together with an upgrade note.
- The alias loader puts the real docsgpt spec back on the shared module object
after import (the import machinery stamped the alias spec on it, which made
importlib.reload rename the module and skip re-execution) and delegates
get_code/get_source/get_filename to the target loader, so
python -m application.<name> runs.
- Each legacy application.* task name is registered as its own task object,
a subclass carrying the old name. Registering the same object under two
keys made Celery's tracer log every run under whichever name it built last.
- The redbeat key prefix stays redbeat:docsgpt:; the three schedule_syncs
entries get stable names instead. redbeat tracks its static entries and
deletes the ones that vanish from beat_schedule at start-up, and rewrites the
task path of named entries in place, so neither a prefix bump nor a cleanup
pass is needed (checked against redbeat 2.4.2 with a seeded Redis).
The backend import package is now docsgpt, the name it will carry on PyPI;
application was far too generic to install into anyone's site-packages.
git mv plus a mechanical rewrite of every import, dotted string and path
reference: 734 Python files, the compose files, Dockerfile, workflows, docs,
setup scripts, devcontainer, k8s manifests, vscode config, pytest and coverage
config, .gitignore. Behaviour is unchanged.
Kept for one release:
- A top-level application package whose meta-path finder resolves
application.x.y to the already-imported docsgpt.x.y object, so old imports
and entry points (celery -A application.app.celery,
uvicorn application.asgi:asgi_app) keep working with a FutureWarning.
- Celery registers every application.* task name as an alias of its
docsgpt.* task on start-up, so messages queued by the previous release still
run. The redbeat key prefix moves to redbeat:docsgpt:v2: so schedule entries
the previous release wrote are left unread instead of firing twice.
The backend image builds from the repository root (docker build -f
docsgpt/Dockerfile .) so it can ship the alias package; a root .dockerignore
allow-lists docsgpt/ and application/ and keeps caches, local data, .env
files, the sample index files and the Dockerfile out. Compose and the image
workflows point at the new context.
- The frontend image ran the Vite dev server in development mode, so
.env.development supplied its defaults (notification banner, Google client
id, local API host). The static build only loads .env.production, so the
build stage now copies .env.development in as the baseline and the compose
files pass every VITE_* the app reads through from .env; the runtime script
skips empty values so a blank passthrough keeps the build-time default.
.dockerignore kept only the .local variants out.
- VITE_DISABLE_SOURCE_FE disables sources only when it is the string true.
- DoclingParser: find_spec raises when docling itself is absent; the install
hint now covers that path, with a regression test.
- verify_offline: direct tests for verify(); the PR image check builds and
verifies the -docling variant as well as slim.
- Workflows this branch adds or rewrites pin actions by commit, pass the
release tag through env instead of template expansion, and do not persist
checkout credentials.
- OCR guide no longer claims pre-built images never include docling.
settings.EMBEDDINGS_NAME still defaults to mpnet so an upgraded deployment
keeps its index; new installs only get granite because setup.sh writes it to
.env. The standalone compose always starts on fresh volumes, so it defaults
EMBEDDINGS_NAME to granite (overridable from .env or the shell), and the
Docker guide's hand-written .env examples name the model too.
OMP_NUM_THREADS=4 capped torch in the old image, but FastEmbed runs on
onnxruntime, which ignores it and sizes its pool to the host's core count.
A CPU-limited container still reports every host core, so embedding ran with
64 threads on a 4-CPU sandbox and took up to 12x longer per file. The image
now sets EMBEDDINGS_THREADS=4 next to the existing caps; the settings guide
documents the knob.
The worker hands finished indexes to the API through an internal endpoint
that rejects every request while INTERNAL_KEY is unset, so a .env written by
hand from the docs' minimal example made every upload end in a 401. setup.sh
generates the key; the standalone compose header and the Docker guide now
generate one too.
A named volume mounted on /app/inputs, /app/indexes or /app/vectors inherits
the ownership of the image directory, so the image creates them as appuser;
before this the volume came up root-owned and every upload failed with a
permission error unless the container ran as root. docker-compose-standalone.yaml
still runs backend and worker as root, like docker-compose-hub.yaml, so it
also works with image tags that predate these directories.
requirements-docling.txt adds the PyTorch CPU index, which uv resolves only
with UV_INDEX_STRATEGY=unsafe-best-match (pip is unaffected); the file header
and the docs say so and point uv users at uv sync --extra docling.
Backend (arc53/docsgpt): 4.5 GB compressed -> 0.9 GB with both embedding
models and tiktoken baked in.
- torch/transformers gone from the default install (docling extra only).
- Ubuntu 24.04 ships python3.12: no deadsnakes PPA, no software-properties-
common; every pin is a wheel, so no gcc/g++/rust in the builder.
- COPY --chown and a prefetch that runs as the process user replace the
trailing chown -R, which duplicated the 600 MB model layer.
- .dockerignore keeps __pycache__, .coverage, local indexes and .env out.
- EXTRAS build arg (INSTALL_DOCLING kept as an alias); the docling variant
also bakes docling's layout/table/RapidOCR models (DOCLING_ARTIFACTS_PATH)
and tesseract, and drops only the discovery documents of Google APIs the
app never builds.
- FLASK_DEBUG env removed (unused); OCI labels added.
Frontend (arc53/docsgpt-fe): 302 MB Vite dev server -> 25 MB static build
behind nginx. VITE_* variables are injected at container start into
/config.js and read through src/env.ts, so the image no longer needs a
rebuild per deployment; docker-compose.yaml keeps hot reload via the dev
target.
Publishing: every release and develop build now pushes a slim tag and a
-docling tag (docling engine + models + tesseract). docker-compose-hub.yaml
takes DOCSGPT_IMAGE_TAG / DOCSGPT_IMAGE_VARIANT; docker-compose-standalone.yaml
runs the stack from pre-built images without a checkout and is attached to
each release. setup.sh selects the -docling variant for OCR instead of
requiring a local build. A new workflow builds the image on PRs that touch
it and runs verify_offline under --network none; lint checks the exported
requirements match uv.lock.
requirements.txt pinned torch and transformers in core although only docling
needs them, and on Linux torch pulls the CUDA 13 stack: 2.7 GB of the 3.0 GB
wheel download. Direct dependencies now live in pyproject.toml, uv.lock pins
everything, and application/requirements*.txt are exported from the lock by
scripts/export_requirements.sh (each file is the core set plus one extra).
The docling extra pins torch/torchvision/transformers itself and, on Linux,
resolves torch from the CPU-only PyTorch index (no nvidia packages). milvus
(pymilvus + milvus-lite, which pulls pyarrow) is the second extra.
application/core/optional_deps.py is the one place install hints come from;
the milvus store and the docling call sites use it so a missing extra fails
with the exact command to run.
- append_compression_point only skips a point when both query_index and
compressed_summary are present and match the last one; points without
those fields (as in the repository tests) were all being treated as
duplicates.
- The incremental compression tail and the orchestrator's "anything new
since the last point" check exclude the visible summary row, which the
prompt already receives through existing_compressions.
- Summary rows carry a persisted metadata marker; replay filters on the
marker, and falls back to the label only for rows written before it that
have no tool calls and no per-turn metadata, so a user who types the
label text keeps their turn.
- The prompt_cache_key is a hash of the user id, never the id itself.
- Describe truncation="auto" as dropping the oldest items.
In store mode every user turn chained onto the previous response, so the
provider's stored transcript grew without bound (measured: 889k prompt
tokens for a 37k-token saved history) while every local guard, the
compression pipeline included, measured the saved history. Each chained
tool round also re-sent the system message, which the server appends rather
than dedupes, and a saved compression point was applied exactly once, in the
turn that made it.
Chaining is now bounded. A turn starts from the saved history when the
previous turn's reported prompt reached the chain budget (default: the
model's context window), when the conversation was compressed after that
turn was produced, or when OPENAI_RESPONSES_CHAIN_ACROSS_TURNS is off.
Chained rounds omit an unchanged system head (hash carried in the persisted
Responses state). truncation="auto" is available behind a setting as a
backstop against a chain that outgrows the model's window.
Compression: a saved point is applied at every turn start; the threshold
counts the summary plus the queries after the point instead of the raw
history; re-compression summarises only the tail on top of the last point;
the mid-execution path marks itself persisted and resets the provider chain
so the rebuilt messages are the context; an empty summary is rejected; the
visible "[Context Compression Summary]" rows are no longer replayed as
history; appending the same point twice is a no-op.
Cache hints: a per-user prompt_cache_key and an optional
prompt_cache_retention on Responses API calls.
Measured on Azure with the same client shape as production (stateless
OpenAI client, server-side tools, PDF part): tokens billed on the sixth turn
fell from 58k to 35k, tool rounds add tens of tokens instead of ~2.8k, the
turn after a compression reused the saved summary in under two seconds
instead of re-summarising, and the round after a mid-execution compression
started from the compressed context instead of the full stored transcript.
Conflicts, and how each was taken:
- application/core/settings.py — ours. The renamed OCR_ENABLED /
OCR_ATTACHMENTS_ENABLED / OCR_MIN_CHARS_PER_PAGE accept main's
DOCLING_OCR_* spellings as AliasChoices, so nothing is dropped.
- application/Dockerfile — both. Main's install layers plus the
INSTALL_DOCLING build arg.
- application/parser/file/constants.py — both imports.
- deployment/docker-compose.yaml — both. The INSTALL_DOCLING /
INSTALL_TESSERACT build args on backend and worker, and main's
-Q docsgpt,parsing,embeddings, which query embedding needs.
- tests/conftest.py — theirs. Both sides fixed the same pytest-postgresql
9.0.0 autocommit= breakage; main's spelling is the one already on main.
- application/requirements.txt — the comments claimed different reasons
torch is in core. Main's is the true one now: it removed
sentence-transformers, so docling is torch's only remaining consumer.
Two things the merge broke without conflicting:
- onnxruntime. This branch moved it out of core into the docling extra;
main meanwhile made it the runtime local embeddings execute on
(fastembed). Git took the deletion, leaving fastembed with no pinned
runtime in a repo that pins everything. Restored to core, and no longer
pinned twice from the extra.
- The frontend copy of ATTACHMENT_PARSER_EXTENSIONS. The backend list is
derived and picked up the anydoc suffixes; the hand-kept frontend mirror
did not, so the composer would refuse files the API accepts.
tests/parser/file/test_constants.py is what caught it.
ruff, pytest (9897 passed), frontend build and docs build all pass. The
image build is unverified: no Docker daemon on this machine.
setup.ps1 wrote OCR_ENABLED=true but never INSTALL_TESSERACT=true, so a
Windows user answering yes to the OCR question ended up with OCR on and no
engine in the image; it also claimed tesseract was "shipped in the Docker
image", which this change makes false, and offered OCR for the pre-built
Docker Hub images that cannot include it. Mirror setup.sh: skip the question
for hub images (naming all three settings the DeepSeek path needs), and bake
tesseract in for locally built ones.
The upgrade callout said earlier images always included tesseract. They never
did -- they included docling, and OCR ran on the RapidOCR engine bundled with
it, needing no system package. It also covered only OCR_ENABLED, missing
OCR_ATTACHMENTS_ENABLED, which is a separate switch onto the same native OCR
path.
Five defects from a review of the embeddings work, four of them silent.
- Write local files atomically. `LocalStorage.save_file` streamed straight onto
the destination, so an interrupted write left a truncated file. `reembed`
rewrites every index it touches, and a half-written `index.faiss` loads at
neither the old width nor the new one -- the source was unrecoverable, with
no backup and no temp file left behind. Bytes now land beside the destination
and move into place with `os.replace`. S3 was already safe (single PUT).
- Read pgvector chunks a page at a time. `reembed_pgvector` materialised every
`(id, text)` row for a source before embedding -- ~1.6 GB at 200k chunks and
several times that for non-Latin scripts, with the `PGresult` held alongside
until the cursor closed. Inside the shipped 4Gi limit, while also holding the
model, that is an OOMKill -- which is exactly the SIGKILL the point above
turned into a destroyed index. It now walks the source by keyset.
- Bound the first wave of delegated embeds. The failure cooldown is only latched
once the first `get()` returns, so every request already in flight paid the
full EMBEDDINGS_DELEGATE_TIMEOUT: measured 64 threads all timing out together,
and at the shipped 60s across a 96-thread WSGI pool that is an API serving
nothing at all, health checks included. One caller now probes while the rest
fail fast; after a single success the gate leaves the path entirely.
- Ship EMBEDDINGS_NAME commented in .env-template. The comment directly above it
says to leave it commented when upgrading, and the line shipped set. Any value
reaching `.env` lands in `model_fields_set`, which makes `resolve_embeddings_pin`
bail -- so a template-derived `.env` disabled the legacy pin outright and
repointed a populated index at a different 768-dim model, where no width check
fires. The pin already picks granite for a fresh install and mpnet for an
existing one, so nothing needs to be set by hand.
- Stamp `sources.model` on wiki sources. They were created with the column NULL
and then embedded like any other source, and the boot check reads NULL as
"pre-dates the column, therefore the legacy model" -- reporting a correctly
embedded source as stale on every startup of every process. Stamped at
creation, and again on each page re-embed so existing rows heal.
The two docs that promised the FAISS index survives a failed run said so of the
embed only; both now describe the write, and upgrading.mdx says to stop ingest
for the duration.
Query embedding moved to the Celery worker, but nothing that ships was
updated to consume the queue it dispatches to.
- Add `embeddings` to every worker `-Q` list (compose x3, k8s, devcontainer,
sandbox README). Without it a search blocked for EMBEDDINGS_DELEGATE_TIMEOUT
and then answered with no retrieved context, because classic_rag swallows the
dispatch error and skips the source -- bad answers, not an error.
- Skip the task_postrun heap reclaim for the embed task. The full gc.collect()
was written for docling/torch parses; on a worker holding the ONNX model it
measured ~86ms against ~8ms for the embed itself, a 9x slowdown of the round
trip for a task that allocates a few kilobytes.
- Resolve the installation pin in the re-embed script. It never imports
application.app, so an install pinned in app_metadata with no EMBEDDINGS_NAME
set -- every stock k8s deployment, whose manifests carry no embedding config
-- would rewrite its whole index with the legacy default and stamp
sources.model to match, then be told by the boot warning to run it again.
- Fail fast for 30s after a failed dispatch. fanout.embed_questions falls back
to letting each store embed its own query, so one dead-worker retrieval paid
the timeout once in the fan-out and again per source.
- Forget the task result. Nothing reads it back: the key is per-dispatch UUID,
not content-addressed, so a repeated query mints another. Left alone every
search leaked ~17KB for result_expires (7 days) into the Redis the broker
shares -- on the bundled k8s manifest (1Gi, no maxmemory policy) that is an
OOMKill that takes the broker with it.
- Release the model ensure_vector_schema loads to read the width of an
unregistered model, in a process that delegates and would never call it.
The width still comes from the model, not the table, so the mismatch check
the hook exists for keeps working.
- Correct the docs that said otherwise: embeddings.md claimed the standard
deployment worked unchanged, upgrading.mdx said no action was needed, and
the settings table listed none of the three delegation settings.
The API embeds every query it serves, so it held its own copy of the model:
~890 MB it never needed. EMBEDDINGS_DELEGATE_TO_WORKER (on by default) sends
the text to the Celery worker instead and gets the vector back, taking an API
process from 1176 MB to 285 MB with no ONNX Runtime imported at all. The client
embeds locally when it finds itself inside a worker task, so the worker never
dispatches to itself -- the same self-deadlock DOCUMENT_PARSE_QUEUE avoids on
the parsing side. EMBEDDINGS_BASE_URL still wins over it, and remains the right
answer for production.
ensure_vector_schema was constructing the embeddings instance purely to read
.dimension off it, loading several hundred MB of ONNX into every API and worker
process at import. For a model the registry describes that is a lookup; only an
unregistered name now falls back to loading.
EMBEDDINGS_BATCH_SIZE was sizing two unrelated things: chunks per store
transaction (and per remote embed request) and documents per ONNX forward pass.
Each pass pads every input up to its longest, and that waste grows with the
square of chunk length, so at the 1250-token default a batch of 32 peaked at
6.6 GB and took 326s where a batch of 1 peaked at 2.9 GB and took 90s. The
forward pass is now sized by EMBEDDINGS_MODEL_BATCH_SIZE, defaulting to 1;
storage and remote batching are unchanged at 32.
reembed embeds in-process: a batch job that walks the whole index should not
round-trip every chunk through a broker, and loading the model there reports a
real failure instead of timing out against an empty queue.
Also drops the mpnet zip download from the docs and the devcontainer, which
pointed at a SentenceTransformers export with no ONNX graph and had been inert
since the FastEmbed swap; corrects the claim that any sentence-transformers
model works; and settles the Configuring/Settings pages on what the registry
and the repository metadata actually decide.
Follow-up review pass over the embeddings branch.
- Fold an oversized header back into the body, and drop header duplication
when it would leave under a quarter of the chunk budget. A header at or
over max_tokens collapsed the body budget to one token, so a document
became one chunk per body token, each still over the cap: a 95 KB file
produced 20k chunks of 2563 tokens against a 1250 cap. Also clamp
max_tokens to at least 1, as the strategy chunkers already do.
- Emit a header-only document as its own chunk. With no body piece to
attach it to, splitting returned nothing and the document was dropped
from the index with no error and no log line.
- Skip add_custom_model for a repository FastEmbed already ships. It
rejects a name it knows, so configuring any of its ~30 built-ins
(MiniLM, bge, e5, gte, ...) failed every embed call and every query.
- Decide "the user chose this model" by comparing against the field
default rather than model_fields_set, which is true for anything read
from .env. Every setup script has always written EMBEDDINGS_NAME, so an
upgraded remote-embeddings install inherited mpnet's 384-token window
and silently clipped ~80% off every chunk.
- Cut tiktoken splits at character offsets instead of decoding each token
window. A multi-byte character straddling a boundary decoded to U+FFFD
on both sides, destroying one character at roughly one boundary in five
on CJK text -- including at the default max_tokens of 2000.
- Let the re-embed script open a FAISS index whose width does not match
the configured model. That mismatch is the main reason to run it, and
the error recommending the script was raised by the script itself, so
the advice failed on every source.
- Re-embed graph_nodes.name_embedding when GraphRAG is enabled. Those
vectors seed every traversal and share the chunk vectors' width, so a
same-width model swap left the graph retrieving from the old space with
nothing to report it.
- Prefetch the models before copying the application source, so editing
any file no longer re-downloads ~780 MB of artifacts on every build.
- Mirror the setup.sh embedding menu into setup.ps1: granite default,
legacy mpnet as an explicit option, and both engine flows updated.
Windows users were otherwise stranded on mpnet with no granite path.
- Drop the unused EmbeddingsWrapper.tokenizer property.
Follow-up to the embeddings work, from a review pass over the branch.
- Route the OpenAI/Azure key handling through the model registry instead of
matching the canonical name literally, so the `text-embedding-ada-002`
alias the registry now accepts also reaches the Azure deployment name
rather than failing every embed with DeploymentNotFound.
- Fall back to a default width where the embeddings model reports no
dimension. A model outside the registry returns None rather than no
attribute, so `getattr` with a default did not catch it and the width
reached the DDL as `vector(None)` / `list_size=None`.
- Point HF_HUB_CACHE at the prefetch directory. Chunking loads the tokenizer
through `tokenizers`, which reads the hub cache, so a fresh container
fetched over the network on first ingest and an offline one silently fell
back to cl100k.
- Charge a token that collapses a long unbroken run by its character span.
WordPiece emits one [UNK] for any word over its character limit, which made
base64 and minified content count as near-zero tokens, so nothing split it
and oversized chunks reached the embedding server.
- Preserve chunk ids and honour --batch-size when rebuilding a FAISS index.
Fresh uuids orphaned GraphRAG's graph_node_chunks rows, and the whole index
went out in a single embed call on remote servers.
- Document that granite runs an int8-quantised graph, and scope the
SentenceTransformer parity claim to mpnet's fp32 graph, which is where it
was measured.
- Correct the embeddings docs: a matching dimension is not a matching model,
so a same-width swap raises nothing and silently degrades retrieval.
