Signing: refactor interfaces
This is a big API-breaking change cleaning up the signing interfaces. Initially, these interfaces were GPG/OpenPGP-specific. When EGit added new signers and signature verifiers that called an external GPG executable, they were found inadequate and were extended to be able to pass in the GpgConfig to get access to the "gpg.program" setting. With the introduction of X.509 S/MIME signing, it was discovered that the interfaces were still not quite adequate, and the "Gpg" prefix on the class names were confusing. Since 7.0 is a major version bump, I'm taking this chance to overhaul these interfaces from ground up. For signing, there is a new Signer interface. With it goes a SignerFactory SPI interface, and a final Signers class managing the currently set signers. By default, signers for the different signature types are created from the signer factories, which are discovered via the ServiceLoader. External code can install its own signers, overriding the default factories. For signature verification, exactly the same mechanism is used. This simplifies the setup of signers and signature verifiers, and makes it all more regular. Signer instances just get a byte[] to sign and don't have to worry about ObjectBuilders at all. SignatureVerifier instances also just get the data and signature as byte[] and don't have to worry about extracting the signature from a commit or tag, or about what kind of signature it is. Both Signers and SignatureVerifiers always get passed the Repository and the GpgConfig. The repository will be needed in an implementation for SSH signatures because gpg.ssh.* configs may need to be loaded explicitly, and some of those values need the current workspace location. For signature verification, there is exactly one place in core JGit in SignatureVerifiers that extracts signatures, determines the signature type, and then calls the right signature verifier. Change RevTag to recognize all signature types known in git (GPG, X509, and SSH). Change-Id: I26d2731e7baebb38976c87b7f328b63a239760d5 Signed-off-by: Thomas Wolf <twolf@apache.org>
