version_added: "0.0.1"
short_description: Deploy software (or files) from git checkouts
description:
    - Manage I(git) checkouts of repositories to deploy files or software.
extends_documentation_fragment: action_common_attributes
options:
    repo:

        type: str

        aliases: [ name ]
    dest:
        description:
            - The path of where the repository should be checked out. This
              is equivalent to C(git clone [repo_url] [directory]). The repository
              named in I(repo) is not appended to this path and the destination directory must be empty. This
              parameter is required, unless I(clone) is set to C(false).
        type: path
        required: true
    version:
        description:
            - What version of the repository to check out. This can be
              the literal string C(HEAD), a branch name, a tag name.
              It can also be a I(SHA-1) hash, in which case I(refspec) needs
              to be specified if the given revision is not already available.
        type: str
        default: "HEAD"
    accept_hostkey:
        description:
            - Will ensure or not that "-o StrictHostKeyChecking=no" is present as an ssh option.
            - Be aware that this disables a protection against MITM attacks.
            - Those using OpenSSH >= 7.5 might want to set I(ssh_opts) to 'StrictHostKeyChecking=accept-new'
              instead, it does not remove the MITM issue but it does restrict it to the first attempt.
        type: bool
        default: 'no'
        version_added: "1.5"
    accept_newhostkey:
        description:
            - As of OpenSSH 7.5, "-o StrictHostKeyChecking=accept-new" can be
              used which is safer and will only accepts host keys which are
              not present or are the same. if C(true), ensure that
              "-o StrictHostKeyChecking=accept-new" is present as an ssh option.
        type: bool
        default: 'no'
        version_added: "2.12"
    ssh_opts:
        description:
            - Options git will pass to ssh when used as protocol, it works via C(git)'s
              GIT_SSH/GIT_SSH_COMMAND environment variables.
            - For older versions it appends GIT_SSH_OPTS (specific to this module) to the
              variables above or via a wrapper script.
            - Other options can add to this list, like I(key_file) and I(accept_hostkey).
            - An example value could be "-o StrictHostKeyChecking=no" (although this particular
              option is better set by I(accept_hostkey)).
            - The module ensures that 'BatchMode=yes' is always present to avoid prompts.
        type: str
        version_added: "1.5"

    key_file:
        description:
            - Specify an optional private key file path, on the target host, to use for the checkout.

    refspec:
        description:
            - Add an additional refspec to be fetched.
              If version is set to a I(SHA-1) not reachable from any branch
              or tag, this option may be necessary to specify the ref containing
              the I(SHA-1).
              Uses the same syntax as the C(git fetch) command.
              An example value could be "refs/meta/config".

              number or revisions. The minimum possible value is C(1), otherwise
              ignored. Needs I(git>=1.9.1) to work correctly.

    update:
        description:
            - If C(false), do not retrieve new revisions from the origin repository.
            - Operations like archive will work on the existing (old) repository and might
              not respond to changes to the options version or remote.
        type: bool
        default: 'yes'
        version_added: "1.2"
    executable:
        description:
            - Path to git executable to use. If not supplied,
              the normal mechanism for resolving binary paths will be used.
        type: path
        version_added: "1.4"
    bare:
        description:
            - If C(true), repository will be created as a bare repo, otherwise
              it will be a standard repo with a workspace.
        type: bool
        default: 'no'
        version_added: "1.4"
    umask:
        description:

              option, skipping sub-modules.
        type: bool
        default: 'yes'
        version_added: "1.6"

        type: bool

    track_submodules:
        description:
            - If C(true), submodules will track the latest commit on their
              master branch (or other branch specified in .gitmodules).  If
              C(false), submodules will be kept at the revision specified by the
              main project. This is equivalent to specifying the --remote flag
              to git submodule update.
        type: bool
        default: 'no'
        version_added: "1.8"

    verify_commit:
        description:
            - If C(true), when cloning or checking out a I(version) verify the
              signature of a GPG signed commit. This requires git version>=2.1.0
              to be installed. The commit MUST be signed and the public key MUST
              be present in the GPG keyring.
        type: bool
        default: 'no'
        version_added: "2.0"

    archive:
        description:
            - Specify archive file path with extension. If specified, creates an
              archive file of the specified format containing the tree structure
              for the source tree.
              Allowed archive formats ["zip", "tar.gz", "tar", "tgz"].
            - This will clone and perform git archive from local directory as not
              all git servers support git archive.

        version_added: "2.4"

    archive_prefix:
        description:

        version_added: "2.10"
        type: str

    separate_git_dir:
        description:
            - The path to place the cloned repository. If specified, Git repository

    gpg_whitelist:
        description:
           - A list of trusted GPG fingerprints to compare to the fingerprint of the
             GPG-signed commit.
           - Only used when I(verify_commit=yes).
           - Use of this feature requires Git 2.6+ due to its reliance on git's C(--raw) flag to C(verify-commit) and C(verify-tag).

notes:
    - "If the task seems to be hanging, first verify remote host is in C(known_hosts).
      SSH will prompt user to authorize the first contact with a remote host.  To avoid this prompt,
      one solution is to use the option accept_hostkey. Another solution is to
      add the remote host public key in C(/etc/ssh/ssh_known_hosts) before calling
      the git module, with the following command: ssh-keyscan -H remote_host.com >> /etc/ssh/ssh_known_hosts."
