Bumps the python-runtime group with 3 updates in the / directory: fastapi, starlette and pydantic.

Updates fastapi from 0.142.2 to 0.152.0

Release notes

Sourced from fastapi's releases.

0.152.0

Validation errors for header parameter models now report the HTTP header name, such as int-val, instead of the Python field name, int_val. Explicit aliases, Header(convert_underscores=False), and Pydantic models with loc_by_alias=False keep their existing behavior.

Fixes

• 🐛 Fix header model validation errors to report HTTP header names. PR #16538 by @​tiangolo.

0.151.0

JSON request bodies now distinguish an explicit null from an omitted value. For individual Body parameters, null is validated as None: nullable types accept it, and non-nullable types reject it even when a default is defined. Defaults and default factories apply only when the value is omitted. This applies both to parameters inside JSON objects and to parameters representing the entire body. Clients that used null to request a default should omit the value instead.

When a JSON object is expected because of Body(embed=True) or multiple body parameters, sending null as the entire body now returns a validation error.

Breaking Changes

• 🐛 Distinguish JSON null from omitted body values. PR #16536 by @​tiangolo.

0.150.0

When no file is selected, browsers submit a file part with an empty filename and empty content. FastAPI now treats this as missing: required file fields return a validation error, and fields with defaults or default factories use them. Unselected inputs are ignored in lists of files. Named zero-byte files are still accepted.

Breaking Changes

• 🐛 Treat unselected browser file inputs as missing. PR #16534 by @​tiangolo.

0.149.0

Browsers submit empty text inputs as empty strings (""). FastAPI now treats empty scalar form values as missing in form models, matching individual Form parameters. Required fields return a validation error. Fields with defaults or default factories use them and remain unset in model_dump(exclude_unset=True).

Empty strings inside lists are preserved. Omitted boolean form fields still become False. JSON requests and direct Pydantic validation are unchanged.

Breaking Changes

• 🐛 Treat empty scalar values as missing in form models. PR #16529 by @​tiangolo.

0.148.0

Defaults for omitted Query, Header, Cookie, and Form parameters and model fields are no longer treated as user input. Defaults are not validated unless validate_default=True is enabled. If you rely on validators running for omitted values, enable default validation with Field(validate_default=True) for model fields or, for example, Query(validate_default=True) for individual parameters. Body(validate_default=True) is now honored too.

For parameter models, applying a default no longer marks a field as explicitly set, so model_dump(exclude_unset=True) excludes it. Default factories run once, and validation errors no longer include injected defaults in input.

Omitted boolean form fields still become False and count as explicitly set.

Breaking Changes

• 🐛 Fix default handling for request parameters and models. PR #16527 by @​tiangolo.

0.147.0

Omitted bool and bool | None form fields are now interpreted as False, matching unchecked HTML checkboxes. This applies to individual Form parameters and form models, including required fields and fields with defaults of True or None. The inferred value is considered explicitly set, including in model_dump(exclude_unset=True).

JSON requests and direct Pydantic validation are unchanged. See Boolean Form Fields.

Updates starlette from 1.7.0 to 1.9.0

Release notes

Sourced from starlette's releases.

Version 1.9.0

This release streams TestClient response bodies, so client.stream() returns before the application finishes. It also escapes path delimiters when building URLs, matches host names case-insensitively, and keeps every existing Vary header.

Changed

• Stream TestClient response bodies, so client.stream() returns before the application finishes. Closing an unfinished streamed response now cancels the application #3491.

Fixed

• Percent-encode ?, #, \ and a leading // in the request path when building request.url, and \ and a leading // in url_path_for #3671.
• Use the byte length for Content-Length when the response body is a typed or multidimensional memoryview #3622.
• Include HEAD in the Allow header of HTTPEndpoint 405 responses when GET is defined #3585.
• Match host names case-insensitively in Host routing and TrustedHostMiddleware #3542.
• Preserve every existing Vary header in MutableHeaders.add_vary_header(), used by GZipMiddleware and SessionMiddleware #3675.

Full changelog: 1.8.0...1.9.0

Version 1.8.0

This release adds HTTP 103 Early Hints, preserves response trailers through GZipMiddleware, and stops FileResponse transfers when clients disconnect. Starlette now requires Python 3.11.

Added

• Add Request.send_early_hints() for HTTP 103 Early Hints through the ASGI http.response.early_hint extension #3435.

Changed

• Require Python 3.11 or later, dropping support for Python 3.10 #3592.
• Exclude native gRPC media types (application/grpc and application/grpc+...) from GZipMiddleware compression by default #3565.
• Send http.response.start immediately in GZipMiddleware for responses with an existing Content-Encoding, status 206, or an excluded content type, instead of waiting for the first body chunk #3631.
• Resolve the multipart charset once per request instead of once per field #3618.

Fixed

• Preserve response trailers through GZipMiddleware #3565.
• Stop FileResponse transfers when the client disconnects #3523.
• Stop multipart range responses when the file ends before a range is complete, instead of looping forever #3583.
• Ignore Range when If-Range contains a weak ETag #3567.
• Include Allow: GET, HEAD in StaticFiles 405 responses #3640.
• Close Request.stream() generators deterministically, avoiding "Exception ignored" errors with stacked BaseHTTPMiddleware #3628.
• Add Vary: Cookie when Session.pop() removes an existing key #3186.
• Emit Max-Age=0 on the session cookie when SessionMiddleware uses max_age=0 #3651.
• Bracket IPv6 hostnames in URL.replace() #3617.
