//! # libgit2 bindings for Rust //! //! This library contains bindings to the [libgit2][1] C library which is used //! to manage git repositories. The library itself is a work in progress and is //! likely lacking some bindings here and there, so be warned. //! //! [1]: https://libgit2.github.com/ //! //! The git2-rs library strives to be as close to libgit2 as possible, but also //! strives to make using libgit2 as safe as possible. All resource management //! is automatic as well as adding strong types to all interfaces (including //! `Result`) //! //! ## Creating a `Repository` //! //! The `Repository` is the source from which almost all other objects in git-rs //! are spawned. A repository can be created through opening, initializing, or //! cloning. //! //! ### Initializing a new repository //! //! The `init` method will create a new repository, assuming one does not //! already exist. //! //! ```no_run //! # #![allow(unstable)] //! use git2::Repository; //! //! let repo = match Repository::init("/path/to/a/repo") { //! Ok(repo) => repo, //! Err(e) => panic!("failed to init: {}", e), //! }; //! ``` //! //! ### Opening an existing repository //! //! ```no_run //! # #![allow(unstable)] //! use git2::Repository; //! //! let repo = match Repository::open("/path/to/a/repo") { //! Ok(repo) => repo, //! Err(e) => panic!("failed to open: {}", e), //! }; //! ``` //! //! ### Cloning an existing repository //! //! ```no_run //! # #![allow(unstable)] //! use git2::Repository; //! //! let url = "https://github.com/alexcrichton/git2-rs"; //! let repo = match Repository::clone(url, "/path/to/a/repo") { //! Ok(repo) => repo, //! Err(e) => panic!("failed to clone: {}", e), //! }; //! ``` //! //! To clone using SSH, refer to [RepoBuilder](./build/struct.RepoBuilder.html). //! //! ## Working with a `Repository` //! //! All derivative objects, references, etc are attached to the lifetime of the //! source `Repository`, to ensure that they do not outlive the repository //! itself. #![doc(html_root_url = "https://docs.rs/git2/0.18")] #![allow(trivial_numeric_casts, trivial_casts)] #![deny(missing_docs)] #![warn(rust_2018_idioms)] #![cfg_attr(test, deny(warnings))] use bitflags::bitflags; use libgit2_sys as raw; use std::ffi::{CStr, CString}; use std::fmt; use std::str; use std::sync::Once; pub use crate::apply::{ApplyLocation, ApplyOptions}; pub use crate::attr::AttrValue; pub use crate::blame::{Blame, BlameHunk, BlameIter, BlameOptions}; pub use crate::blob::{Blob, BlobWriter}; pub use crate::branch::{Branch, Branches}; pub use crate::buf::Buf; pub use crate::cherrypick::CherrypickOptions; pub use crate::commit::{Commit, Parents}; pub use crate::config::{Config, ConfigEntries, ConfigEntry}; pub use crate::cred::{Cred, CredentialHelper}; pub use crate::describe::{Describe, DescribeFormatOptions, DescribeOptions}; pub use crate::diff::{Deltas, Diff, DiffDelta, DiffFile, DiffOptions}; pub use crate::diff::{DiffBinary, DiffBinaryFile, DiffBinaryKind, DiffPatchidOptions}; pub use crate::diff::{DiffFindOptions, DiffHunk, DiffLine, DiffLineType, DiffStats}; pub use crate::email::{Email, EmailCreateOptions}; pub use crate::error::Error; pub use crate::index::{ Index, IndexConflict, IndexConflicts, IndexEntries, IndexEntry, IndexMatchedPath, }; pub use crate::indexer::{Indexer, IndexerProgress, Progress}; pub use crate::mailmap::Mailmap; pub use crate::mempack::Mempack; pub use crate::merge::{AnnotatedCommit, MergeOptions}; pub use crate::message::{ message_prettify, message_trailers_bytes, message_trailers_strs, MessageTrailersBytes, MessageTrailersBytesIterator, MessageTrailersStrs, MessageTrailersStrsIterator, DEFAULT_COMMENT_CHAR, }; pub use crate::note::{Note, Notes}; pub use crate::object::Object; pub use crate::odb::{Odb, OdbObject, OdbPackwriter, OdbReader, OdbWriter}; pub use crate::oid::Oid; pub use crate::packbuilder::{PackBuilder, PackBuilderStage}; pub use crate::patch::Patch; pub use crate::pathspec::{Pathspec, PathspecFailedEntries, PathspecMatchList}; pub use crate::pathspec::{PathspecDiffEntries, PathspecEntries}; pub use crate::proxy_options::ProxyOptions; pub use crate::push_update::PushUpdate; pub use crate::rebase::{Rebase, RebaseOperation, RebaseOperationType, RebaseOptions}; pub use crate::reference::{Reference, ReferenceNames, References}; pub use crate::reflog::{Reflog, ReflogEntry, ReflogIter}; pub use crate::refspec::Refspec; pub use crate::remote::{ FetchOptions, PushOptions, Refspecs, Remote, RemoteConnection, RemoteHead, RemoteRedirect, }; pub use crate::remote_callbacks::{CertificateCheckStatus, Credentials, RemoteCallbacks}; pub use crate::remote_callbacks::{TransportMessage, UpdateTips}; pub use crate::repo::{Repository, RepositoryInitOptions}; pub use crate::revert::RevertOptions; pub use crate::revspec::Revspec; pub use crate::revwalk::Revwalk; pub use crate::signature::Signature; pub use crate::stash::{StashApplyOptions, StashApplyProgressCb, StashCb, StashSaveOptions}; pub use crate::status::{StatusEntry, StatusIter, StatusOptions, StatusShow, Statuses}; pub use crate::submodule::{Submodule, SubmoduleUpdateOptions}; pub use crate::tag::Tag; pub use crate::time::{IndexTime, Time}; pub use crate::tracing::{trace_set, TraceLevel}; pub use crate::transaction::Transaction; pub use crate::tree::{Tree, TreeEntry, TreeIter, TreeWalkMode, TreeWalkResult}; pub use crate::treebuilder::TreeBuilder; pub use crate::util::IntoCString; pub use crate::version::Version; pub use crate::worktree::{Worktree, WorktreeAddOptions, WorktreeLockStatus, WorktreePruneOptions}; // Create a convinience method on bitflag struct which checks the given flag macro_rules! is_bit_set { ($name:ident, $flag:expr) => { #[allow(missing_docs)] pub fn $name(&self) -> bool { self.intersects($flag) } }; } /// An enumeration of possible errors that can happen when working with a git /// repository. // Note: We omit a few native error codes, as they are unlikely to be propagated // to the library user.

This means that we're picking up an OpenSSL // dependency on non-Windows platforms (where it has its own HTTPS // subsystem). As a result, we need to link to OpenSSL. // // Now actually *linking* to OpenSSL isn't so hard. We just need to make // sure to use pkg-config to discover any relevant system dependencies for // differences between distributions like CentOS and Ubuntu. The actual // trickiness comes about when we start *distributing* the resulting // binaries. Currently Cargo is distributed in binary form as nightlies, // which means we're distributing a binary with OpenSSL linked in. // // For historical reasons, the Linux nightly builder is running a CentOS // distribution in order to have as much ABI compatibility with other // distributions as possible. Sadly, however, this compatibility does not // extend to OpenSSL. Currently OpenSSL has two major versions, 0.9 and 1.0, // which are incompatible (many ABI differences). The CentOS builder we // build on has version 1.0, as do most distributions today. Some still have // 0.9, however. This means that if we are to distribute the binaries built // by the CentOS machine, we would only be compatible with OpenSSL 1.0 and // we would fail to run (a dynamic linker error at runtime) on systems with // only 9.8 installed (hopefully). // // But wait, the plot thickens! Apparently CentOS has dubbed their OpenSSL // library as `libssl.so.10`, notably the `10` is included at the end. On // the other hand Ubuntu, for example, only distributes `libssl.so`. This // means that the binaries created at CentOS are hard-wired to probe for a // file called `libssl.so.10` at runtime (using the LD_LIBRARY_PATH), which // will not be found on ubuntu. The conclusion of this is that binaries // built on CentOS cannot be distributed to Ubuntu and run successfully. // // There are a number of sneaky things we could do, including, but not // limited to: // // 1. Create a shim program which runs "just before" cargo runs. The // responsibility of this shim program would be to locate `libssl.so`, // whatever it's called, on the current system, make sure there's a // symlink *somewhere* called `libssl.so.10`, and then set up // LD_LIBRARY_PATH and run the actual cargo. // // This approach definitely seems unconventional, and is borderline // overkill for this problem. It's also dubious if we can find a // libssl.so reliably on the target system. // // 2. Somehow re-work the CentOS installation so that the linked-against // library is called libssl.so instead of libssl.so.10 // // The problem with this approach is that systems with 0.9 installed will // start to silently fail, due to also having libraries called libssl.so // (probably symlinked under a more appropriate version). // // 3. Compile Cargo against both OpenSSL 1.0 *and* OpenSSL 0.9, and // distribute both. Also make sure that the linked-against name of the // library is `libssl.so`. At runtime we determine which version is // installed, and we then the appropriate binary. // // This approach clearly has drawbacks in terms of infrastructure and // feasibility. // // 4. Build a nightly of Cargo for each distribution we'd like to support. // You would then pick the appropriate Cargo nightly to install locally. // // So, with all this in mind, the decision was made to *statically* link // OpenSSL. This solves any problem of relying on a downstream OpenSSL // version being available. This does, however, open a can of worms related // to security issues. It's generally a good idea to dynamically link // OpenSSL as you'll get security updates over time without having to do // anything (the system administrator will update the local openssl // package). By statically linking, we're forfeiting this feature. // // The conclusion was made it is likely appropriate for the Cargo nightlies // to statically link OpenSSL, but highly encourage distributions and // packagers of Cargo to dynamically link OpenSSL. Packagers are targeting // one system and are distributing to only that system, so none of the // problems mentioned above would arise. // // In order to support this, a new package was made: openssl-static-sys. // This package currently performs a fairly simple task: // // 1. Run pkg-config to discover where openssl is installed. // 2. If openssl is installed in a nonstandard location, *and* static copies // of the libraries are available, copy them to $OUT_DIR. // // This library will bring in libssl.a and libcrypto.a into the local build, // allowing them to be picked up by this crate. This allows us to configure // our own buildbots to have pkg-config point to these local pre-built // copies of a static OpenSSL (with very few dependencies) while allowing // most other builds of Cargo to naturally dynamically link OpenSSL. // // So in summary, if you're with me so far, we've statically linked OpenSSL // to the Cargo binary (or any binary, for that matter) and we're ready to // distribute it to *all* linux distributions. Remember that our original // intent for openssl was for HTTPS support, which implies that we need some // for of CA certificate store to validate certificates.
