Release v0.23.0

Bumps version from 0.22.0 to 0.23.0. Promotes dev → main.

Changelog

Added

• Sending a method by hash: MthdsAPIClient.missing_blobs and upload_blob call the protocol's optional blob routes, typed by BlobRef, MissingBlobsRequest, MissingBlobsResult, MissingBlob and UploadTarget, and prepare_files and prepare_files_from_contents build a request's files from a listed tree or from bytes at hand: inline when the map, written as compact JSON in UTF-8 so that Base64 counts as its encoded text, is at most DEFAULT_INLINE_TREE_MAX_BYTES (256 KiB), or when the runner keeps no blob store, and otherwise uploading only the blobs the runner lacks and sending every file by hash. Files are read and hashed off the event loop, an upload carries exactly its target's headers and never the API key, and a refused one raises BlobUploadError, whose URL keeps no userinfo, query or fragment.
• VersionInfo.blob_store: the version() handshake reads whether the runner keeps a blob store, false when the runner does not say.
• EmptyMethodTreeError: list_method_tree and list_method_tree_at_root refuse a directory whose own tree is empty with this MethodTreeRefusedError, which also carries the listing's root, excluded_files, excluded_directories and raw_paths, so a caller that lists a directory to find the packages and repositories nested in it learns them even when the directory holds nothing but nested packages. The refusal's code stays empty_tree and its record stays the conformance corpus's, so a caller catching MethodTreeRefusedError is unaffected; its message now says when the root is itself a virtual environment.
• Resolving a file reference over a set of tree paths: resolve_reference_in_paths runs the standard's resolution steps, the same implementation resolve_reference runs, in a set of tree paths rather than a MethodTree, for a runtime that holds only a tree's listing; with holder=None it resolves from the root a reference written in no file of the tree, is_one_file_tree gives the one-file tree's refusal, and a refusal as not in the tree names no membership rule, which a set of paths does not record. Steps 1 and 3 in URL context are public as url_path_of and percent_decode_url_path, which refuses as reference_invalid, naming the path, what step 3 refuses, and lexical_join takes holder=None to join from the root.

Changed

• A method travels as files (Breaking): MthdsAPIClient.execute, start and validate, the MTHDSProtocol interface and PipelexRunner take the method as files, a map from tree path to file entry typed MethodFiles, in place of mthds_contents, and the protected _post_validate seam takes files too; an empty map is refused before any request. A runner that still accepts inline mthds_contents receives it through extra, and PipelexRunner writes the map out as a directory for pipelex run bundle and pipelex validate bundle, refusing a hash entry.
• Typed file entries (Breaking): encode_file_entry and encode_file_map return FileEntry values, a str, a Base64FileEntry or a HashFileEntry, instead of plain dictionaries, and pydantic_core.to_json writes them in their wire form.

Summary by cubic

Promotes mthds to v0.23.0, the breaking release in which a method travels as a files map of typed file entries instead of inline mthds_contents, and the API client can send a tree by hash through the protocol's optional blob routes.

Breaking changes

• execute, start, validate, MTHDSProtocol, and PipelexRunner now take the method as files; inline mthds_contents is only passed through extra.
• encode_file_entry and encode_file_map return typed FileEntry values instead of plain dictionaries.

Added

• prepare_files sends a tree inline when its compact JSON is at most 256 KiB or the runner keeps no blob store, otherwise uploading only the blobs the runner lacks and referencing each file by hash.
• VersionInfo.blob_store reports runner blob-store support; uploads never send the API key, and a refused upload raises BlobUploadError.
• EmptyMethodTreeError carries the root and what the listing kept out.
• resolve_reference_in_paths resolves a reference over a set of tree paths, with url_path_of and percent_decode_url_path public.
