import os, warnings, logging
from autotest_lib.client.common_lib import error, revision_control
from autotest_lib.client.bin import os_dep
from autotest_lib.server import utils, installable_object
class InstallableGitRepo(installable_object.InstallableObject):
This class helps to pick a git repo and install it in a host.
def __init__(self, repodir, giturl, weburl=None):
self.repodir = repodir
self.giturl = giturl
self.weburl = weburl
self.git_repo = revision_control.GitRepo(self.repodir, self.giturl,
# default to same remote path as local
self._build = os.path.dirname(self.repodir)
# base install method
def install(self, host, builddir=None):
Install a git repo in a host. It works by pushing the downloaded source
code to the host.
@param host: Host object.
@param builddir: Directory on the host filesystem that will host the
source code.
# allow override of target remote dir
if builddir:
self._build = builddir
# push source to host for install'Pushing code dir %s to host %s', self.source_material,
host.send_file(self.source_material, self._build)
def gitcmd(self, cmd, ignore_status=False):
Wrapper for a git command.
@param cmd: Git subcommand (ex 'clone').
@param ignore_status: Whether we should supress error.CmdError
exceptions if the command did return exit code !=0 (True), or
not supress them (False).
return self.git_repo.gitcmd(cmd, ignore_status)
def get(self, **kwargs):
This method overrides baseclass get so we can do proper git
clone/pulls, and check for updated versions. The result of
this method will leave an up-to-date version of git repo at
'giturl' in 'repodir' directory to be used by build/install
@param **kwargs: Dictionary of parameters to the method get.
self.source_material = self.repodir
return self.git_repo.get(**kwargs)
def get_local_head(self):
Get the top commit hash of the current local git branch.
@return: Top commit hash of local git branch
return self.git_repo.get_local_head()
def get_remote_head(self):
Get the top commit hash of the current remote git branch.
@return: Top commit hash of remote git branch
return self.git_repo.get_remote_head()
def is_out_of_date(self):
Return whether this branch is out of date with regards to remote branch.
@return: False, if the branch is outdated, True if it is current.
return self.git_repo.is_out_of_date()
def is_repo_initialized(self):
Return whether the git repo was already initialized (has a top commit).
@return: False, if the repo was initialized, True if it was not.
return self.git_repo.is_repo_initialized()
def get_revision(self):
Return current HEAD commit id
return self.git_repo.get_revision()
def checkout(self, remote, local=None):
Check out the git commit id, branch, or tag given by remote.
Optional give the local branch name as local.
@param remote: Remote commit hash
@param local: Local commit hash
@note: For git checkout tag git version >= 1.5.0 is required
return self.git_repo.checkout(remote, local)
def get_branch(self, all=False, remote_tracking=False):
Show the branches.
@param all: List both remote-tracking branches and local branches (True)
or only the local ones (False).
@param remote_tracking: Lists the remote-tracking branches.
return self.git_repo.get_branch(all, remote_tracking)
