feat(auth): migrate user identities from integer to UUIDv4#43aniebiet-afia merged 3 commits intomainfrom
Conversation
- Altered `User.id` and `VerificationToken.user_id` from auto-incrementing integers to `uuid.UUID` to prevent user enumeration and improve security. - Generated and applied an Alembic migration to safely truncate development tables and apply `USING uuid_generate_v4()` to cast existing column schema types. - Updated Pydantic schemas (`UserResponse`, `LoginResponse`, `UserRegisteredEvent`, `MediaUploadPayload`) to enforce strict `uuid.UUID` typing. - Fixed `TypeError: Object of type UUID is not JSON serializable` in the `POST /login` FastAPI `JSONResponse` endpoint by enabling `mode="json"` on `model_dump()`. - Updated CRUD services and email verification signatures to accept `uuid.UUID` globally. - Resolved `MissingGreenlet` SQLAlchemy DBAPI crash by establishing `psycopg2-binary` as the sync fallback for `asyncpg` within `session.py`.

In general, to fix an unused global variable you either remove the assignment if it serves no purpose, or, if it is intentionally unused, rename it to follow an “unused” naming convention (e.g. prefix with unused_ or use _-style names). Here, branch_labels is set to None and is not used anywhere; Alembic does not require it to be present for a simple linear migration. The safest and cleanest fix without changing existing behavior is to delete the branch_labels line entirely and leave revision, down_revision, and depends_on untouched. This keeps the migration semantics the same while eliminating the unused variable.
Concretely, in alembic/versions/7f066a8213a8_change_user_id_to_uuid.py, remove line 17:
branch_labels: Union[str, Sequence[str], None] = NoneNo new imports, functions, or other definitions are needed.

To fix an unused global variable, either remove its assignment if it has no side effects and is not needed, or rename it to a clearly “unused” style if it must remain. Here, depends_on is assigned None with no side effects, and Alembic does not require depends_on to be present when it is None. Removing the line will not change behavior.
Concretely, in alembic/versions/7f066a8213a8_change_user_id_to_uuid.py, delete the line that assigns depends_on (line 18). No new imports, functions, or variables are required; we only remove this redundant declaration and leave the rest of the Alembic revision identifiers unchanged.

Inline comments:
In @.env.example:
- Line 17: The DATABASE_URL entry in .env.example currently has surrounding
quotes which trips dotenv-linter; update the DATABASE_URL variable
(DATABASE_URL) by removing the surrounding double quotes so it appears as an
unquoted assignment (e.g., DATABASE_URL=postgresql+psycopg2://...) to satisfy
the linter and preserve the same connection string.
In `@alembic_output.txt`:
- Around line 1-3: Remove the committed Alembic run log file alembic_output.txt
from the repository (delete the file and stage the removal) and update
.gitignore to prevent future commits by adding an entry for alembic_output.txt
or a suitable pattern (e.g., alembic_*.txt or *.txt logs) so Alembic execution
logs are ignored going forward; ensure the removal is included in the same
commit that updates .gitignore.
In `@alembic/versions/7f066a8213a8_change_user_id_to_uuid.py`:
- Around line 44-55: The downgrade() implementation is incomplete and will fail
converting UUIDs back to INTEGER; either implement a proper reversal that
mirrors upgrade() (remove/recreate foreign key constraints around changing
users.id and verification_tokens.user_id, perform safe data conversion/casting
or a migration script that maps UUIDs back to integer ids, and recreate the FK)
or explicitly disable downgrade by replacing downgrade() with a single raise
NotImplementedError("Downgrade from UUID to INTEGER is not supported");
reference the downgrade() function and the alter_column calls on 'users' id and
'verification_tokens' user_id when making this change.
- Around line 27-28: The migration currently executes op.execute('TRUNCATE TABLE
users CASCADE') which is data-destructive; either replace this with a safe
conversion (add a new UUID column on users, backfill UUIDs from existing ids,
update foreign keys, then drop/rename columns) or if truncation is intentional
for fresh deployments add a prominent WARNING comment above the op.execute line
and a runtime guard that prevents running unless an explicit DEV_ONLY flag is
set; reference the truncate call and the migration file's upgrade function to
locate where to add the safe backfill logic or the warning/guard.
- Around line 14-18: The Alembic revision module (look for the module defining
the symbols revision and down_revision in the new migration) fails CI due to
formatting; run the project's formatter (black) on that migration file so the
top-level declarations (revision, down_revision, branch_labels, depends_on) and
surrounding imports/whitespace conform to Black’s style, then re-run tests/CI.
In `@alembic/versions/e1a664780dc6_add_meeting_model.py`:
- Around line 14-18: The file fails the project's Black formatting check; run
the formatter or apply Black-style changes to this Alembic revision file (the
block containing the module-level variables revision and down_revision) so it
matches the project's formatting rules—e.g., run `black
alembic/versions/e1a664780dc6_add_meeting_model.py` or reformat the lines around
the revision: str = 'e1a664780dc6' and down_revision: Union[str, Sequence[str],
None] = '19dc9714d9ea' to satisfy `black --check .`.
- Around line 21-31: The migration titled "Add Meeting model" is empty: update
the upgrade() and downgrade() functions or clarify intent—either implement the
missing Meeting model DDL in upgrade()/downgrade() (referencing the Alembic
revision functions upgrade and downgrade) or leave them empty but (1) change the
migration message/revision title to accurately describe its purpose (e.g.,
"checkpoint before UUID migration") and (2) remove the unused import sqlalchemy
as sa and add a short comment inside upgrade()/downgrade() explaining that the
migration is intentionally empty for now. Ensure the revision title and
docstring reflect the chosen action.
In `@app/core/config.py`:
- Around line 24-30: Add explicit bounds validation for the security-critical
constants in config.py: validate ACCESS_TOKEN_EXPIRE_MINUTES,
REFRESH_TOKEN_EXPIRE_DAYS, VERIFICATION_TOKEN_EXPIRE_HOURS,
MAX_FAILED_LOGIN_ATTEMPTS, and ACCOUNT_LOCKOUT_DAYS after they are loaded from
env (or set to defaults) and either clamp them to sane minimums or raise a clear
exception when values are ≤ 0; for example enforce ACCESS_TOKEN_EXPIRE_MINUTES
>= 1, REFRESH_TOKEN_EXPIRE_DAYS >= 1, VERIFICATION_TOKEN_EXPIRE_HOURS >= 1,
MAX_FAILED_LOGIN_ATTEMPTS >= 1, and ACCOUNT_LOCKOUT_DAYS >= 1 using a simple
check that raises ValueError with a descriptive message mentioning the offending
symbol (e.g., ACCESS_TOKEN_EXPIRE_MINUTES) so misconfiguration fails fast
instead of allowing invalid token/lockout behavior.
In `@app/core/security.py`:
- Around line 21-23: SecurityService currently signs JWTs without validating
runtime config; add a fail-fast check in SecurityService.__init__ to validate
the SECRET_KEY (not equal to the known placeholder, non-empty, and meets minimum
entropy/length) and validate JWT_ALGORITHM is a secure algorithm (e.g., starts
with "HS" only if SECRET_KEY strong or prefer "RS"/"ES"); if checks fail, raise
a RuntimeError with a clear message. Also add the same guard at entrypoints that
sign tokens (e.g., create_access_token, create_refresh_token or any methods
around lines referenced 81-85 and 108-112) to avoid issuing tokens if config is
insecure, and ensure any logging includes the offending config key name but
never prints secret values.
In `@app/db/session.py`:
- Around line 16-32: There is a mismatch between the app's _coerce_sync_url
(which forces psycopg2) and Alembic's async config; either make migrations
synchronous or commit to async migrations—pick one: (A) To align migrations with
the app, change alembic.ini to use postgresql+psycopg2 URI and swap
async_engine_from_config/any async-specific code in alembic/env.py to the
synchronous engine_from_config and standard run_migrations_online/offline flow
so Alembic uses psycopg2, or (B) to keep async migrations, document this and
ensure asyncpg is listed in dependencies and keep alembic.ini and env.py using
async_engine_from_config; update tests/README accordingly. Reference:
_coerce_sync_url, alembic.ini, and alembic/env.py (async_engine_from_config).
In `@app/services/account_lockout.py`:
- Around line 84-88: The logger.warning call is logging user-controlled email
directly; wrap the email with the existing sanitize_log_args helper (as used in
app/api/v1/endpoints/auth.py) before passing it to logger.warning to prevent log
injection, and add an import for sanitize_log_args if missing; specifically
update the arguments passed to logger.warning (the call to logger.warning in
account_lockout.py) to use sanitize_log_args(email) so sanitized output is
logged.
In `@fail_log.txt`:
- Around line 1-42: Remove the committed test output file fail_log.txt from the
repository and add an entry for test output logs (e.g., fail_log.txt and
test_output.txt) to .gitignore so these transient artifacts are not tracked;
then update the failing assertion in the test method
test_returns_access_token_and_user_id (TestLoginSuccess) to account for JSON
serialization by comparing body["user_id"] to str(user.id) or by parsing
body["user_id"] into a UUID before comparing to user.id (i.e., change the
comparison involving body["user_id"] and user.id to use matching types).
In `@test_output_full.txt`:
- Around line 1-30: The committed test output file test_output_full.txt is a
local CI/test artifact and should be removed from version control: remove
test_output_full.txt from the repository (use git rm --cached or equivalent to
stop tracking but keep local copy if desired), add "test_output_full.txt" (or a
pattern like "*.log" or "test_output*.txt") to your .gitignore so it won’t be
re-added, commit the removal and .gitignore change, and instead include test
summaries or attach CI artifacts to the PR/CI system rather than committing the
raw log file.
- Around line 25-27: Pytest is warning because the helper class TestConsumer
(subclassing BaseConsumer) is being collected as a test class; to fix, either
rename the class to a non-test name (e.g., MockConsumer) or add the attribute
__test__ = False to the TestConsumer class definition so pytest skips it; update
the class declaration for TestConsumer (the subclass of BaseConsumer)
accordingly and run the test collection to confirm the warning is gone.

Incomplete downgrade() will fail.
The downgrade() function attempts to convert UUID columns back to INTEGER but:
- Doesn't drop/recreate the foreign key constraint (upgrade does)
- Doesn't handle data conversion (UUIDs can't cast to integers)
- Will fail with a constraint violation or type conversion error

Alembic configuration mismatch: migrations use asyncpg while application uses psycopg2.
The _coerce_sync_url function converts DATABASE_URL from asyncpg to psycopg2, allowing the application to run with synchronous SQLAlchemy. However, alembic.ini (line 89) still hardcodes postgresql+asyncpg://... and alembic/env.py uses async_engine_from_config(), creating a divergence:
- App runtime: psycopg2 (sync)
- Migrations: asyncpg (async)
Either update alembic.ini and env.py to use synchronous migrations with psycopg2, or clarify that async migrations are intentional and ensure asyncpg is installed alongside psycopg2.

Remove this development artifact from the repository.
Test output logs should not be committed to the codebase. These are transient development artifacts that add noise to the repository history. Consider adding fail_log.txt and test_output.txt to .gitignore.
Additionally, this log indicates the test at test_auth_login.py:188 compares a JSON string (body["user_id"]) against a UUID object (user.id). The test assertion should account for the JSON serialization:
# Instead of:
assert body["user_id"] == user.id
# Use:
assert body["user_id"] == str(user.id)
# Or:
assert UUID(body["user_id"]) == user.id🤖 Prompt for AI Agents

Clean up the pytest collection warning for TestConsumer.
PytestCollectionWarning indicates pytest is trying to collect TestConsumer as a test class. In tests/test_kafka/test_consumer.py:13-19, this class is a fixture helper, not a test case. Rename it (e.g., MockConsumer) or set __test__ = False on the class to suppress this warning and keep test output clean.

helper class TestConsumer (subclassing BaseConsumer) is being collected as a
test class; to fix, either rename the class to a non-test name (e.g.,
MockConsumer) or add the attribute __test__ = False to the TestConsumer class
definition so pytest skips it; update the class declaration for TestConsumer
(the subclass of BaseConsumer) accordingly and run the test collection to
confirm the warning is gone.

To fix the problem, remove the unused import so that every imported name is actually referenced in the file. This keeps the code cleaner and avoids unnecessary dependencies.
Concretely, in alembic/versions/e1a664780dc6_add_meeting_model.py, delete the line import sqlalchemy as sa (line 12 in the snippet). No additional methods, imports, or definitions are required, because nothing in the file currently uses sa. The rest of the file, including the typing and alembic.op imports and the upgrade/downgrade stubs, can remain unchanged.
