Updates uvicorn from 0.39.0 to 0.52.4

Release notes

Sourced from uvicorn's releases.

Version 0.52.4

Fixed

• Remove duplicate Date headers from accepted WebSocket handshakes with websockets-sansio (#3078)

Full Changelog: Kludex/uvicorn@0.52.3...0.52.4

Version 0.52.3

Changed

• Update zttp to 0.0.24 and use its combined receive path, improving HTTP/1.1 request parsing performance (#3067)

Full Changelog: Kludex/uvicorn@0.52.2...0.52.3

Version 0.52.2

Fixed

• Update zttp to 0.0.22, fixing bodyless request receives and improving HTTP/1 request parsing performance (#3063)

Full Changelog: Kludex/uvicorn@0.52.1...0.52.2

Version 0.52.1

Fixed

• Complete the closing handshake on server-initiated WebSocket closes in the websockets-sansio and wsproto implementations, waiting for the client's close reply with a 10 second timeout instead of resetting the connection (#3053)
• Add missing write flow control to the websockets-sansio implementation, preventing data truncation on server-initiated closes with large in-flight payloads (#3048)
• Handle connection loss while a WebSocket write is waiting on backpressure (#3050)
• Remove duplicate Content-Type and Content-Length headers from WebSocket denial responses on the websockets-sansio implementation, and deliver non-UTF-8 denial bodies intact (#3041)

Full Changelog: Kludex/uvicorn@0.52.0...0.52.1

Version 0.52.0

This release adds an experimental HTTP/1.1 implementation backed by zttp, a sans-IO HTTP parser I've been developing on the side: a core written in Zig, with bindings to Python. It has been running under a fuzzer for some weeks now, and has been through multiple rounds of security auditing.

It is still experimental, so don't put it in front of production traffic yet. Try it with --http zttp, and please send any feedback to the issue tracker.

Added

• Add an experimental zttp HTTP/1.1 implementation, selectable with --http zttp (#2979)

Fixed

• Keep non-ASCII WebSocket request headers intact with websockets 17.0, which encodes them with ISO-8859-1 (#3036)

Full Changelog: Kludex/uvicorn@0.51.0...0.52.0

Version 0.51.0

What's Changed

• Restart workers with overlap on SIGHUP for near-zero-downtime reloads by @​Kludex in Kludex/uvicorn#3025

Updates pydantic-settings from 2.14.2 to 2.15.0

Release notes

Sourced from pydantic-settings's releases.

v2.15.0

Highlights

Behavior changes

• case_sensitive now applies to init kwargs and config-file sources (#900). InitSettingsSource and the JSON/TOML/YAML config sources previously ignored case_sensitive. Since it defaults to False, case-insensitive matching is now the default for these sources — e.g. Settings(TeSt=...) now populates a test field where it previously did not. Nested keys are still matched case-sensitively.
• Fields with unresolved forward references now emit a warning (#901). Settings sources can silently fail to resolve such fields; they now raise IncompleteFieldDefinitionWarning telling you to call model_rebuild(). If you have filterwarnings = error configured, this may surface as a new failure.
• Non-JSON env values for strict fields now raise ValidationError (#926) instead of a less specific error.

New features

• Show environment variable names in CLI help via cli_show_env_vars=True (#860), so generated --help output doubles as configuration documentation.
• PYDANTIC_SETTINGS_DEBUG for debugging settings resolution (#906, #913). Set it to a truthy value with DEBUG logging enabled to see each source's contribution in priority order, which source won for each value, and which env_file/secret files were probed, loaded, or skipped — the long-standing "why isn't my .env being picked up?" question.
• toml_table_header for regular TOML files (#882, #886, #887), letting you root settings at a nested table in any TOML file, not just pyproject.toml.
• Traversable support for JSON/TOML/YAML file sources (#902), so you can load config packaged inside a distribution — including files inside a zip or wheel — via importlib.resources.files(...) without casting to Path.
• GCP: project_id can come from an earlier settings source (#878), rather than only from the constructor or GOOGLE_CLOUD_PROJECT.

Bug fixes

• Fix env vars not loading on Windows with case_sensitive=True (#894). Windows upper-cases os.environ keys, so fields raised Field required instead of picking up their values.
• Read secret files as UTF-8 instead of the platform locale encoding (#917). On Windows code pages such as cp1252 this silently corrupted non-ASCII secrets.
• Fix AliasPath on nested model fields not JSON-decoding env values (#898).
• Fix case-insensitive matching for optional nested models (#905).
• Fix dotenv extras being wrongly claimed by a complex field sharing a name prefix (#912) — e.g. dbx_token being swallowed by a db: dict field.
• Fix nested_model_default_partial_update=True corrupting discriminated unions (#876).
• Fix Secret subclasses crashing when loaded from the environment (#920).
• Fix enum names not parsing through nested annotations such as Optional[Annotated[MyEnum, ...]] with env_parse_enums=True (#910).
• An empty yaml_config_section now falls back to defaults instead of raising AttributeError: 'NoneType' object has no attribute 'keys' (#914).
• NestedSecretsSettingsSource no longer follows symlinks pointing outside secrets_dir (#889).
• GCP: skip the list_secrets call when case_sensitive=True (#862), lowering the required IAM permissions to just roles/secretmanager.secretAccessor.
• AWS: types-boto3[secretsmanager] is no longer required at runtime (#880).

Documentation

• Document JSON parsing of complex env values, plus a comma-separated-values recipe (#919).
• Recommend an async settings loading pattern (#908).
• Clarify behavior when an unprefixed value is present in a dotenv file (#895).
• Clarify environment variable helper descriptions (#867) and fix assorted typos (#904).

Updates python-dotenv from 1.2.2 to 1.2.3

Release notes

Sourced from python-dotenv's releases.

v1.2.3

Fixed

• Strip a leading UTF-8 BOM from .env file contents so the first variable is no longer silently lost when the file is saved with BOM (e.g. by some JetBrains IDEs on Windows) by [@​h1whelan] in #640
• set_key now escapes backslashes, so values containing them (Windows paths, regular expressions) survive a write/read round-trip. Quoted values ending in an escaped backslash are no longer mis-parsed as an escaped quote, which used to swallow the following lines by [@​dchaudhari7177] in #680
• dotenv run now prints a friendly error instead of a traceback when no command is given by [@​bbc2] in #606
• Cache the parsed result for empty .env files so repeated dotenv_values/load_dotenv calls no longer re-read the file by [@​ReinerBRO] in #638
