feat(documents): Add v2 upload endpoints - #1179
Merged
Merged
Conversation
Two-step JSON flow replacing multipart upload through the backend: POST /api/v2/documents/upload-url issues a presigned PUT URL, the client uploads directly to S3, then POST /api/v2/documents registers the document. Register verifies the object exists, enforces the 25 MB limit (deleting oversized objects), and rejects duplicate document ids. Transformation stays v1-only.

📝 WalkthroughWalkthroughThe v2 document API now uses JSON requests, presigned staging uploads, and document-specific registration. Storage provides staging and promotion operations. Registration validates size and filename, creates the document record, and removes the staged object. ChangesV2 document upload flow
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The new upload flow can consume unbounded temporary storage, promote bytes that were not size-validated, or leave an orphaned final object that cannot be retried after persistence failure.

In `@backend/app/api/routes/documents_v2.py`:
- Line 85: Update the registration flow around crud.exists and crud.update to
create the record atomically without relying on a separate pre-check. Catch the
database unique-key integrity error, roll back the session, and return HTTP 409
for duplicate registrations while preserving normal success handling.
In `@backend/app/core/cloud/storage.py`:
- Around line 316-319: Update the direct-upload flow around
generate_presigned_url in the storage client to enforce a maximum upload size
before accepting objects. Prefer a presigned POST policy with a
content-length-range condition; otherwise implement an equivalent bucket-side
limit together with cleanup of rejected/unregistered objects and project quota
enforcement.
- Around line 316-319: The upload flow around create_upload_url and
register_document must prevent reuse of the presigned PUT URL after
registration. Store or promote the uploaded object to an immutable final key
during registration, and ensure get_signed_url serves that final key rather than
the still-writable document key; preserve the existing size validation while
blocking subsequent overwrites.
In `@backend/app/tests/api/routes/documents/conftest.py`:
- Around line 19-23: Update the fixture that assigns AWS environment variables
to snapshot each variable’s prior value, restore the original values in a
finally block surrounding yield, and remove variables that were previously unset
instead of leaving test credentials or region behind.
In `@features/documents-v2-presigned-upload/PLAN.md`:
- Line 90: Document an upload-size limit or object-storage lifecycle cleanup
control at features/documents-v2-presigned-upload/PLAN.md:90, addressing
unrestricted put_object uploads and abandoned oversized objects. Update
backend/app/api/docs/documents/upload_url_v2.md:9 to state that
registration-only size enforcement is acceptable only when the selected control
bounds or cleans up abandoned uploads.
- Line 91: Update features/documents-v2-presigned-upload/PLAN.md:91 and
docs/wiki/modules/knowledge-base.md:38 to document a control preventing active
content from being served through v2 signed URLs. Specify either enforcing an
inert response type with attachment disposition on signed GETs and constraining
PUT Content-Type, or restoring validate_document_content validation; apply the
chosen control consistently in both documents.

Review follow-up on the v2 presigned upload.
Endpoints are now verb-free and document_id moves out of the request body:
POST /api/v2/documents/uploads -> 200 {document_id, upload_url, expires_in}
PUT /api/v2/documents/{document_id} -> 201 DocumentPublic
Uploads stage at pending/{storage_path}/{document_id}{ext} and are copied to
the final {storage_path}/{document_id} on registration. The final key is
unchanged from v1, and the key served by get_signed_url was never presigned
for PUT, so a stale upload URL can no longer overwrite a registered document.
The staging prefix leads the key because S3 lifecycle filters are literal
prefixes: with the per-project segment in front, no single rule could reap
abandoned uploads. A rule expiring pending/ after one day is live on the
staging and production buckets.
Baking the extension into the staging key binds the two calls - registering
under a different extension misses the key and returns the ordinary 400 - so
no filename comparison is needed.
Also:
- ObjectNotFoundError lets callers stop unwrapping botocore error codes across
the service boundary
- url_for / staging_url_for are the only places an object key is built
- SignedUpload reports the effective expiry rather than the requested one
- IntegrityError on registration returns 409 instead of 500 when two
registrations race past the exists() check
- register responds with DocumentPublic; DocumentUploadResponse carries a
transformation_job that is always null on v2
- the v2 upload policy moves out of the route into services/documents/registration.py

In `@backend/app/api/docs/documents/initiate_v2.md`:
- Line 9: Correct the filename contract for the initiation and registration
flow: either state that only the filename extension must match between
initiation and step 3, or persist and enforce the complete original filename.
Align the documentation with the implemented staged-key behavior and ensure
registration rejects mismatched extensions if that is the intended contract.
- Line 11: Update the upload-session and pending-object flow documented around
upload_url to enforce a per-project pending storage quota (bytes and/or object
count) or an upload-specific rate limit before accepting new uploads; ensure the
limit applies independently of registration and existing lifecycle expiration.
In `@backend/app/services/documents/registration.py`:
- Line 75: Update the registration flow around verify_staged_object and
storage.copy so promotion is conditional on the staged object retaining the ETag
or version captured during validation. Pass the validated identity as a copy
precondition, and abort without promoting when the staged object has been
replaced.
- Around line 75-76: Update the promotion flow around storage.copy,
storage.delete, and DocumentCrud.update so persistence succeeds before removing
the staged object. Preserve the staged object through a failed database commit,
or implement compensating cleanup and reconciliation that prevents an orphaned
final object and allows retries to recover.

Naming and scope cleanups from review. - STAGING_PREFIX -> PENDING_PREFIX and url_for's flag -> is_pending. "Staging" already means the deploy environment here, and the two appeared side by side in the same sentence; this prefix only ever meant "uploaded, not registered". The prefix value is unchanged, so keys and the lifecycle rule are unaffected. - Document is_pending in url_for's docstring, including the one-day TTL that governs anything written under the prefix. - Fold staging_url_for back into url_for rather than keeping a second function. - upload_url -> upload_signed_url, and finish its truncated field description. - Move validate_filename_format into registration.py so helpers.py and pre_transform_validation return to their state on main. The transformation path is out of scope for this PR and now carries no diff. - Drop the logger lines that sat immediately before a raise: the exception already carries the same facts, and Sentry sees it either way. - Rename crud to document_crud.
storage.delete ran between the copy and the DocumentCrud.update commit, so a failed insert left the final object with no row and nothing to retry from - the client's bytes were already gone. Delete after the row is committed instead: a failed insert leaves the upload retryable, and a pending object nobody comes back for expires on its own. Also correct the initiation contract in the docs. Only the extension is carried across the two calls, not the whole filename, so report.pdf then invoice.pdf is accepted and the step 3 name is what gets stored.

enhancement
Switch the v2 upload from a pre-signed PUT to a pre-signed POST so the 25 MB limit is enforced by S3 as the file uploads (content-length-range) rather than only at registration. An oversized file is rejected outright and never stored. The filename is signed into object metadata (x-amz-meta-filename), so it can no longer be swapped between issuing the ticket and registering, and the client no longer sends it twice — registration reads it back from the object and takes no request body. The pending key drops its extension as a result. Registration copies before it measures: the pending object stays writable through its ticket, so the size is read from the frozen final key, closing the check-then-copy race on the recorded size. Storage gains create_upload_ticket (replacing get_signed_upload_url) and head (size + filename); the v1 get_file_size_kb path is untouched.
The upload response now carries a next_step note — upload to the pre-signed URL, then register the document — and the register response notes that the upload URL is spent, so a client can follow the flow from the responses alone.

Issue
Closes #1169
Summary
v1 streams every upload through the backend (~8s per file). This adds a v2 flow where the file goes straight from the client to S3, in three steps: ask for an upload slot, upload the file, then register the document.
POST/api/v2/documents/uploads{filename}{document_id, upload_url, upload_fields, expires_in}PUT/api/v2/documents/{document_id}DocumentPublicThe upload is a
multipart/form-dataPOST toupload_urlwith every entry inupload_fields, file part last. No API key on that call. Registered files land where a v1 upload would, so existing readers work unchanged.Key points
