Full Changelog: v0.4.0...v0.5.0

v0.4.0

Added

• POST /resolve now dispatches on Content-Type: application/json (or missing) keeps the existing ResolveRequest envelope behavior; application/yaml / application/x-yaml / text/yaml / application/toml / text/plain treat the body as a raw environment file, parsed through conda's env-spec plugin registry. Specs, channels, platforms, and format come from query params on the raw-body dispatch; ?filename= picks the parser when Content-Type alone is ambiguous. Unsupported Content-Types return HTTP 400 with the list of accepted types. This makes curl --data-binary @environment.yml -H 'Content-Type: application/yaml' '.../resolve?format=pixi-lock-v6&platform=linux-64' a one-liner — no jq or JSON wrapping required.
• HTTP API ?format=<name> query parameter on GET/POST /resolve routes the response through conda's exporter plugin registry. The CLI (--format) and HTTP API share the same render_envs helper so both surfaces expose the same set of formats. Unknown formats return HTTP 400 with the available-format list; solver failures on this path return HTTP 500 (exporters can't represent per-platform errors).
• conda-lockfiles >=0.1.1 is now a base dependency, so conda-lock-v1 and rattler-lock-v6/pixi-lock-v6 are available out of the box from both CLI and HTTP API.
• Windows virtual package override via CONDA_PRESTO_WIN_VERSION (default 0) so cross-platform win-* solves get the same treatment as Linux/macOS.
• Per-request abuse/DoS caps: CONDA_PRESTO_MAX_SPECS (default 200, returns 400), CONDA_PRESTO_MAX_PLATFORMS (default 8, returns 400), and CONDA_PRESTO_SOLVE_TIMEOUT_S (default 60s, returns 504).
• Process pool is shut down cleanly via Litestar's on_shutdown hook.

Changed

• HTTP API now returns SolveResult / ResolvedPackage msgspec.Struct instances directly; Litestar encodes them natively to JSON without an intermediate to_dict() conversion.
• CLI default output is now produced by msgspec.json.encode on the same list[SolveResult] the HTTP API returns, pretty-printed via msgspec.json.format(..., indent=2). CLI and HTTP emit identical JSON (modulo whitespace), including a per-platform "error" field (was previously absent from the CLI default). This is an additive change to the schema — correct JSON parsers continue to work.
• POST body fields override query params based on presence, not truthiness. An explicit empty array in the body (e.g. {"platforms": []}) now overrides the corresponding query param, matching the documented behavior.
• Solver error responses surface detail only for an allow-list of known exception types (UnsatisfiableError, PackagesNotFoundError); all other exceptions return a generic "Internal solver error" message. Full detail is still logged server-side.
• Environment-variable parsing is centralized through env_int and env_list helpers: list values now strip whitespace and drop empty parts, and numeric values fail with a clear startup error instead of a raw ValueError from int().

Removed

• resolve-json conda exporter plugin and the conda_environment_exporters hook entry. It duplicated the SolveResult/ResolvedPackage msgspec shape for no good reason; the CLI now produces that shape natively. Minor user-visible consequences:
  • conda presto --format resolve-json ... now errors with "Unknown format". Fix: drop --format; the default output is the same JSON shape (plus a "error" field per platform).
  • HTTP GET/POST /resolve?format=resolve-json returns HTTP 400 for the same reason. Drop the query parameter.
  • conda env export --format resolve-json (invoked from plain conda on an installed prefix, with conda-presto installed) no longer works. This was never conda-presto's intended use case.
• ResolvedPackage.to_dict and SolveResult.to_dict methods: no longer called anywhere; msgspec serializes the structs directly.

Fixed

• HTTP Content-Type on ?format= responses is now derived from the exporter's default_filenames rather than a hand-coded format-name table. YAML-ish formats (environment-yaml, conda-lock-v1, rattler-lock-v6/pixi-lock-v6) are now served as application/yaml instead of text/plain.
• Tempfile lifetime bug in parse_file_content: specs and channels are now extracted while the temp file is still open, preventing races with env-spec plugins that read the file lazily on attribute access.
• README documentation of the index-cache TTL was inaccurate. The on-disk repodata TTL (CONDA_LOCAL_REPODATA_TTL) and the in-memory RattlerIndexHelper cache (no TTL, process-lifetime) are now described separately.

v0.3.0

Added

• Interactive API documentation (Scalar UI) at / with auto-generated OpenAPI 3.1 schema at /openapi.json, replacing the hand-written ~190-line schema dictionary.
• Production middleware: brotli compression with gzip fallback, CORS (configurable via CONDA_PRESTO_CORS_ORIGINS, default *), structured request logging, and rate limiting (configurable via CONDA_PRESTO_RATE_LIMIT, default 300 req/min, 0 to disable).
• New environment variables: CONDA_PRESTO_RATE_LIMIT, CONDA_PRESTO_CORS_ORIGINS, CONDA_PRESTO_LOG_LEVEL.
• Native request body size enforcement via Litestar's request_max_body_size (configurable via CONDA_PRESTO_MAX_BODY_BYTES, default 1 MB).

Changed

• Migrated HTTP API framework from Starlette to Litestar. Typed request validation via ResolveRequest dataclass replaces manual JSON parsing.
• Migrated ResolvedPackage and SolveResult from dataclasses to msgspec.Struct for faster serialization and lower memory. Litestar encodes these natively to JSON without intermediate dicts.
• Startup initialization uses Litestar's on_startup hook with app.state instead of module-level globals.
• Application log level configurable via CONDA_PRESTO_LOG_LEVEL (default INFO).
• Renamed project from conda-resolve to conda-presto (package, CLI subcommand, environment variables, Docker images).

v0.2.1

Added

• Separate Docker image flavors: server (latest) and CLI (cli), built from docker/server.Dockerfile and docker/cli.Dockerfile. The CLI image excludes server dependencies (uvicorn) for a smaller footprint.

v0.2.0

Added

• Configuration module (config.py) with environment variable overrides for all operational settings: CONDA_PRESTO_CHANNELS, CONDA_PRESTO_PLATFORMS, CONDA_PRESTO_CONCURRENCY, CONDA_PRESTO_WORKERS, CONDA_PRESTO_MAX_BODY_BYTES, CONDA_PRESTO_HOST, CONDA_PRESTO_PORT, CONDA_PRESTO_GLIBC_VERSION, CONDA_PRESTO_LINUX_VERSION, CONDA_PRESTO_OSX_VERSION.
• Support for .toml and .json file extensions in the HTTP API file upload endpoint.
• Dynamic OpenAPI schema version derived from package metadata via importlib.metadata.

Changed

• Default fallback channel changed from defaults to conda-forge in both CLI and HTTP API, configurable via CONDA_PRESTO_CHANNELS.
• Unified HTTP API to single /resolve endpoint supporting both GET (query params) and POST (JSON body). Removed old /solve, /solve/environment-yml, and /cache/clear endpoints.
• Request body uses specs field instead of dependencies, and file/filename fields for environment file content instead of raw YAML body.
• POST body fields override query params when both are present.
• Virtual package versions for cross-platform solving are now configurable via environment variables instead of hardcoded.
• Process pool size and server host/port defaults are now configurable via environment variables.
• Updated test suite to match the new /resolve API.

v0.1.1

Added

• Minimal, hardened Docker image using multi-stage build with debian:bookworm-slim and non-root user.
• Docker release workflow publishing multi-arch images (linux/amd64, linux/arm64) to GitHub Container Registry on release and manual dispatch.
• Dependabot configuration for Docker base image updates.
• Automated pixi lockfile update workflow (monthly, via pixi-diff-to-markdown).
• linux-aarch64 platform support.

Fixed

• Default platform detection after server warmup. The warmup loop left a stale platform in context._cache_, causing the server to default to the wrong platform. Now captured once at import time as NATIVE_SUBDIR.
