Responsibilities\n\nCommunity leaders are responsible for clarifying and enforcing our standards of\nacceptable behavior and will take appropriate and fair corrective action in\nresponse to any behavior that they deem inappropriate, threatening, offensive,\nor harmful.\n\nCommunity leaders have the right and responsibility to remove, edit, or reject\ncomments, commits, code, wiki edits, issues, and other contributions that are\nnot aligned to this Code of Conduct, and will communicate reasons for moderation\ndecisions when appropriate.\n\n## Scope\n\nThis Code of Conduct applies within all community spaces, and also applies when\nan individual is officially representing the community in public spaces.\nExamples of representing our community include using an official e-mail address,\nposting via an official social media account, or acting as an appointed\nrepresentative at an online or offline event.\n\n## Enforcement\n\nInstances of abusive, harassing, or otherwise unacceptable behavior may be\nreported to the community leaders responsible for enforcement at\npooya{dot}eimandar{at}gmail{dot}com.\nAll complaints will be reviewed and investigated promptly and fairly.\n\nAll community leaders are obligated to respect the privacy and security of the\nreporter of any incident.\n\n## Enforcement Guidelines\n\nCommunity leaders will follow these Community Impact Guidelines in determining\nthe consequences for any action they deem in violation of this Code of Conduct:\n\n### 1. Correction\n\n**Community Impact**: Use of inappropriate language or other behavior deemed\nunprofessional or unwelcome in the community.\n\n**Consequence**: A private, written warning from community leaders, providing\nclarity around the nature of the violation and an explanation of why the\nbehavior was inappropriate. A public apology may be requested.\n\n### 2. Warning\n\n**Community Impact**: A violation through a single incident or series\nof actions.\n\n**Consequence**: A warning with consequences for continued behavior. No\ninteraction with the people involved, including unsolicited interaction with\nthose enforcing the Code of Conduct, for a specified period of time. This\nincludes avoiding interactions in community spaces as well as external channels\nlike social media. Violating these terms may lead to a temporary or\npermanent ban.\n\n### 3. Temporary Ban\n\n**Community Impact**: A serious violation of community standards, including\nsustained inappropriate behavior.\n\n**Consequence**: A temporary ban from any sort of interaction or public\ncommunication with the community for a specified period of time. No public or\nprivate interaction with the people involved, including unsolicited interaction\nwith those enforcing the Code of Conduct, is allowed during this period.\nViolating these terms may lead to a permanent ban.\n\n### 4. Permanent Ban\n\n**Community Impact**: Demonstrating a pattern of violation of community\nstandards, including sustained inappropriate behavior, harassment of an\nindividual, or aggression toward or disparagement of classes of individuals.\n\n**Consequence**: A permanent ban from any sort of public interaction within\nthe community.\n\n## Attribution\n\nThis Code of Conduct is adapted from the [Contributor Covenant][homepage],\nversion 2.1, available at\n[https://www.contributor-covenant.org/version/2/1/code_of_conduct.html][v2.1].\n\nCommunity Impact Guidelines were inspired by\n[Mozilla's code of conduct enforcement ladder][Mozilla CoC].\n\nFor answers to common questions about this code of conduct, see the FAQ at\n[https://www.contributor-covenant.org/faq][FAQ].

Current implementation is mostly a C++ wrapper over msquic which is written in C, along with a few helpers to simplify and help with common usages such as client/server.\n\nThere are one to one C++ wrapper types for msquic types. including enums and flags, core data types to hold information, and handle types. public methods and member variables are also kind of one to one with similar name, sometimes with a little modification to ease the use.\n\nHandle instances which are async and have callbacks (connection and stream) have internal refcounting, and when running an instance of them will be managed internally and won't be destroyed/closed until stopped or are shut down. this allows, for example, one to start running an instance of connection in a listener callback and not to worry of managing its lifetime. and if an instance wasn't started, once its out of scope, it will automatically be closed.\n\nDue to the way msquic was designed, the parentship of instances like stream by connection and connection/listener by registration must be handled by user of this library. for example: when a connection is closed, the stream will automatically shut down and user must ensure that stream instances held by them will no longer be accessed or avilable.\n\nSo make sure dependent handles **DO NOT** outlive their dependencies. hopefully in the future this will be managed internally.\n\nTo understand these dependencies please refer to `API` overview documenetation of msquic: https://github.com/microsoft/msquic/blob/main/docs/API.md\n\n## Base Data Types\n\nMsquic enums/flags have an equivalent enum classes to be used. for bit flags, `w_flags` is used to handle bitwise operations.\n\nThe header `stream/quic/datatypes/common_flags.hpp` defines common enum flags used throughout the project.\n\nFor alpn name, since it is not forced to be a string, there is `w_alpn_view` in `stream/quic/datatypes/w_alpn.hpp` which represents an alpn name and is simply an alias to `std::span`. it comes with `as_alpn_view` helper method to create view from string views and c strings.\n\nHere is a list of C++ wrapper types and their corresponding msquic types:\n - `w_address` represents `QUIC_ADDRESS`.\n\n - `w_status` and `w_status_code` represent `QUIC_STATUS`. the first is for holding a status code and checking whether it succeeded or failed, and the latter is an enum representing different status codes defined by msquic.\n\n - `w_settings` represents `QUIC_SETTINGS`, having each field as an `std::optional` so it can be easily aggregate initialized with specific field. e.g. `w_settings { .idle_timeout_ms = 2000 }`.\n\n - `w_credential_config` represents `QUIC_CREDENTIAL_CONFIG`, and for convenience there are `w_certificate_` alongside it to represent `QUIC_CERTIFICATE_` and be used with ease to construct a credential config with any certificate without worrying about value semantics.\n\n - `w_registration_config` represents `QUIC_REGISTRATION_CONFIG`, and its fields are accessible through set/get methods.\n\n - `w_new_connection_info` represents `QUIC_NEW_CONNECTION_INFO`, and its fields are readonly, accessible through const methods with same name.\n\n## Events\n\nJust as msquic uses callbacks with event as a parameter, those event types are wrapped and represented by classes.\n\nEvent types are similar to `std::variant`, and to access the underlying event value, it must be visited with an overload set. wolf library provides `system/w_overloaded` to overload lambdas to ease this.\n\nAll event types also have a `name` method to get the underlying type's name string.\n\nThere are no fields, but wrapper classes for each specific event, named as `w__event_`, e.g. `w_listener_event_new_connection`. these event classes hold the underlying data, and provide getter and helper methods to interact with them.\n\nEvents can not be created, copied, or moved. their lifetime is solely in hands of wolf library that passes them to callback/visitor.\n\n - `w_listener_event` represents `QUIC_LISTENER_EVENT`. in `w_listener_event_new_connection` there are accept/reject methods which shouldn't be called more than once or over each other, and if neither is called then the connection will be rejected.\n\n - `w_conection_event` represents `QUIC_CONNEcTION_EVENT`, and just like `w_listener_event_new_connection` there is `w_connection_event_peer_stream_started` that has accept/reject methods and by default rejects if neither is called.\n\n - `w_stream_event` represents `QUIC_STREAM_EVENT`.\n\n## Handles\n\nThe handles in msquic all have the type of `HQUIC`. but here are the common concepts and kinds of handles provided by msquic which have their own api, and wolf has wrapper for them:\n\n - Registration: `w_registration` which on destruction waits on its children to be closed.\n\n - Configuration: `w_configuration`.\n\n - Listener: `w_listener` which starts and works async with callback, but it will shutdown when its last instance goes out of scope.\n\n - Connection: `w_connection` which starts and works async with callback, and will be kept alive/running even if there are no instances of it kept by user. thus user can easily accept/open a new connection and not have to worry about its lifetime.\n\n - Stream: `w_stream` which starts and works async with callbacks, and will be kept alive/running even if there are no instances of it kept by user. thus user can easily accept/open a new stream and not have to worry about its lifetime.\n\nHandles can not be constructed and are created by (commonly named `open`) factory static methods, using boost::leaf for error report and handling.\n\nCallbacks passed to create/set_callback of handle can be any callable and its storage will be internally managed.\n\nWolf doesn't provide the `context` pointer concept of msquic to user of this library, so instead use lambda captures or other C++-based alternatives.\n\n## For Developer/Contributor (Internals)\n\nMsquic's api table is created only once and is provided by singleton-style factory method `internal::w_msquic_api::api`.\n\nAs a C wrapper library there are many scenarios which one C function/type requires another C instance, and for this reason `internal::w_raw_access` pattern is used. classes which wrap a raw/C type declare that as `freind` class and provide desired private api so in any other part in the library if raw access is required, it can be gained via `internal::w_raw_access` can be used and these two types/methods need not to know of each other (necessary for generics). saving us tons of forward declarations and maintenance bookkeepings.\n\nHandles are kept lightweight, only have the `HQUIC` pointer as data member, and all of their required shared data is allocated on heap (the type `context_bundle`) and saved in the handle's context. so the context pointer must never change/written and should be always read for concurrency safety.\n" }, { "path": "manifest.manifest", "content": "\n\n \n \n \n \n \n \n \n \n \n\t \n \n \n \n \n \n \n \n \n \n \n \n" }, { "path": "wolf/.clang-format", "content": "# http://clang.llvm.org/docs/ClangFormatStyleOptions.html\nBasedOnStyle: Google\n# This defaults to 'Auto'.
