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. This is normally + // installed in a standard system location. + // + // Unfortunately, as one might imagine, OpenSSL is configured for where this + // standard location is at *build time*, but it often varies widely + // per-system. Consequently, it was discovered that OpenSSL will respect the + // SSL_CERT_FILE and SSL_CERT_DIR environment variables in order to assist + // in discovering the location of this file (hurray!). + // + // So, finally getting to the point, this function solely exists to support + // our static builds of OpenSSL by probing for the "standard system + // location" of certificates and setting relevant environment variable to + // point to them. + // + // Ah, and as a final note, this is only a problem on Linux, not on OS X. On + // OS X the OpenSSL binaries are stable enough that we can just rely on + // dynamic linkage (plus they have some weird modifications to OpenSSL which + // means we wouldn't want to link statically). + openssl_probe::init_ssl_cert_env_vars(); +} + +#[cfg(any( + windows, + target_os = "macos", + target_os = "ios", + not(feature = "https") +))] +fn openssl_env_init() {} + +unsafe fn opt_bytes<'a, T>(_anchor: &'a T, c: *const libc::c_char) -> Option<&'a [u8]> { + if c.is_null() { + None + } else { + Some(CStr::from_ptr(c).to_bytes()) + } +} + +fn opt_cstr<T: IntoCString>(o: Option<T>) -> Result<Option<CString>, Error> { + match o { + Some(s) => s.into_c_string().map(Some), + None => Ok(None), + } +} + +impl ObjectType { + /// Convert an object type to its string representation. + pub fn str(&self) -> &'static str { + unsafe { + let ptr = call!(raw::git_object_type2string(*self)) as *const _; + let data = CStr::from_ptr(ptr).to_bytes(); + str::from_utf8(data).unwrap() + } + } + + /// Determine if the given git_object_t is a valid loose object type. + pub fn is_loose(&self) -> bool { + unsafe { call!(raw::git_object_typeisloose(*self)) == 1 } + } + + /// Convert a raw git_object_t to an ObjectType + pub fn from_raw(raw: raw::git_object_t) -> Option<ObjectType> { + match raw { + raw::GIT_OBJECT_ANY => Some(ObjectType::Any), + raw::GIT_OBJECT_COMMIT => Some(ObjectType::Commit), + raw::GIT_OBJECT_TREE => Some(ObjectType::Tree), + raw::GIT_OBJECT_BLOB => Some(ObjectType::Blob), + raw::GIT_OBJECT_TAG => Some(ObjectType::Tag), + _ => None, + } + } + + /// Convert this kind into its raw representation + pub fn raw(&self) -> raw::git_object_t { + call::convert(self) + } + + /// Convert a string object type representation to its object type. + pub fn from_str(s: &str) -> Option<ObjectType> { + let raw = unsafe { call!(raw::git_object_string2type(CString::new(s).unwrap())) }; + ObjectType::from_raw(raw) + } +} + +impl fmt::Display for ObjectType { + fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result { + self.str().fmt(f) + } +} + +impl ReferenceType { + /// Convert an object type to its string representation. + pub fn str(&self) -> &'static str { + match self { + ReferenceType::Direct => "direct", + ReferenceType::Symbolic => "symbolic", + } + } + + /// Convert a raw git_reference_t to a ReferenceType. + pub fn from_raw(raw: raw::git_reference_t) -> Option<ReferenceType> { + match raw { + raw::GIT_REFERENCE_DIRECT => Some(ReferenceType::Direct), + raw::GIT_REFERENCE_SYMBOLIC => Some(ReferenceType::Symbolic), + _ => None, + } + } +} + +impl fmt::Display for ReferenceType { + fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result { + self.str().fmt(f) + } +} + +impl ConfigLevel { + /// Converts a raw configuration level to a ConfigLevel + pub fn from_raw(raw: raw::git_config_level_t) -> ConfigLevel { + match raw { + raw::GIT_CONFIG_LEVEL_PROGRAMDATA => ConfigLevel::ProgramData, + raw::GIT_CONFIG_LEVEL_SYSTEM => ConfigLevel::System, + raw::GIT_CONFIG_LEVEL_XDG => ConfigLevel::XDG, + raw::GIT_CONFIG_LEVEL_GLOBAL => ConfigLevel::Global, + raw::GIT_CONFIG_LEVEL_LOCAL => ConfigLevel::Local, + raw::GIT_CONFIG_LEVEL_APP => ConfigLevel::App, + raw::GIT_CONFIG_HIGHEST_LEVEL => ConfigLevel::Highest, + n => panic!("unknown config level: {}", n), + } + } +} + +impl SubmoduleIgnore { + /// Converts a [`raw::git_submodule_ignore_t`] to a [`SubmoduleIgnore`] + pub fn from_raw(raw: raw::git_submodule_ignore_t) -> Self { + match raw { + raw::GIT_SUBMODULE_IGNORE_UNSPECIFIED => SubmoduleIgnore::Unspecified, + raw::GIT_SUBMODULE_IGNORE_NONE => SubmoduleIgnore::None, + raw::GIT_SUBMODULE_IGNORE_UNTRACKED => SubmoduleIgnore::Untracked, + raw::GIT_SUBMODULE_IGNORE_DIRTY => SubmoduleIgnore::Dirty, + raw::GIT_SUBMODULE_IGNORE_ALL => SubmoduleIgnore::All, + n => panic!("unknown submodule ignore rule: {}", n), + } + } +} + +impl SubmoduleUpdate { + /// Converts a [`raw::git_submodule_update_t`] to a [`SubmoduleUpdate`] + pub fn from_raw(raw: raw::git_submodule_update_t) -> Self { + match raw { + raw::GIT_SUBMODULE_UPDATE_CHECKOUT => SubmoduleUpdate::Checkout, + raw::GIT_SUBMODULE_UPDATE_REBASE => SubmoduleUpdate::Rebase, + raw::GIT_SUBMODULE_UPDATE_MERGE => SubmoduleUpdate::Merge, + raw::GIT_SUBMODULE_UPDATE_NONE => SubmoduleUpdate::None, + raw::GIT_SUBMODULE_UPDATE_DEFAULT => SubmoduleUpdate::Default, + n => panic!("unknown submodule update strategy: {}", n), + } + } +} + +bitflags! { + /// Status flags for a single file + /// + /// A combination of these values will be returned to indicate the status of + /// a file.
