A crate for using libcurl as a backend for HTTP git requests with git2-rs. //! //! This crate provides one public function, `register`, which will register //! a custom HTTP transport with libcurl for any HTTP requests made by libgit2. //! At this time the `register` function is unsafe for the same reasons that //! `git2::transport::register` is also unsafe. //! //! It is not recommended to use this crate wherever possible. The current //! libcurl backend used, `curl-rust`, only supports executing a request in one //! method call implying no streaming support. This consequently means that //! when a repository is cloned the entire contents of the repo are downloaded //! into memory, and *then* written off to disk by libgit2 afterwards. It //! should be possible to alleviate this problem in the future. //! //! > **NOTE**: At this time this crate likely does not support a `git push` //! > operation, only clones. #![doc(html_root_url = "https://docs.rs/git2-curl/0.19")] #![deny(missing_docs)] #![warn(rust_2018_idioms)] #![cfg_attr(test, deny(warnings))] use std::error; use std::io::prelude::*; use std::io::{self, Cursor}; use std::str; use std::sync::{Arc, Mutex, Once}; use curl::easy::{Easy, List}; use git2::transport::SmartSubtransportStream; use git2::transport::{Service, SmartSubtransport, Transport}; use git2::Error; use log::{debug, info}; use url::Url; struct CurlTransport { handle: Arc>, /// The URL of the remote server, e.g. "https://github.com/user/repo" /// /// This is an empty string until the first action is performed. /// If there is an HTTP redirect, this will be updated with the new URL. base_url: Arc>, } struct CurlSubtransport { handle: Arc>, service: &'static str, url_path: &'static str, base_url: Arc>, method: &'static str, reader: Option>>, sent_request: bool, } /// Register the libcurl backend for HTTP requests made by libgit2. /// /// This function takes one parameter, a `handle`, which is used to perform all /// future HTTP requests.
