| %prog [<project>...] |
| """ |
| helpDescription = """ |
| The '%prog' command synchronizes local project directories |
| with the remote repositories specified in the manifest. If a local |
| project does not yet exist, it will clone a new local directory from |
| the remote repository and set up tracking branches as specified in |
| the manifest. If the local project already exists, '%prog' |
| will update the remote branches and rebase any new local changes |
| on top of the new remote changes. |
| |
| '%prog' will synchronize all projects listed at the command |
| line. Projects can be specified either by name, or by a relative |
| or absolute path to the project's local directory. If no projects |
| are specified, '%prog' will synchronize all projects listed in |
| the manifest. |
| |
| The -d/--detach option can be used to switch specified projects |
| back to the manifest revision. This option is especially helpful |
| if the project is currently on a topic branch, but the manifest |
| revision is temporarily needed. |
| |
| The -s/--smart-sync option can be used to sync to a known good |
| build as specified by the manifest-server element in the current |
| manifest. The -t/--smart-tag option is similar and allows you to |
| specify a custom tag/label. |
| |
| The -u/--manifest-server-username and -p/--manifest-server-password |
| options can be used to specify a username and password to authenticate |
| with the manifest server when using the -s or -t option. |
| |
| If -u and -p are not specified when using the -s or -t option, '%prog' |
| will attempt to read authentication credentials for the manifest server |
| from the user's .netrc file. |
| |
| '%prog' will not use authentication credentials from -u/-p or .netrc |
| if the manifest server specified in the manifest file already includes |
| credentials. |
| |
| The -f/--force-broken option can be used to proceed with syncing |
| other projects if a project sync fails. |
| |
| The --force-sync option can be used to overwrite existing git |
| directories if they have previously been linked to a different |
| object direcotry. WARNING: This may cause data to be lost since |
| refs may be removed when overwriting. |
| |
| The --no-clone-bundle option disables any attempt to use |
| $URL/clone.bundle to bootstrap a new Git repository from a |
| resumeable bundle file on a content delivery network. This |
| may be necessary if there are problems with the local Python |
| HTTP client or proxy configuration, but the Git binary works. |
| |
| The --fetch-submodules option enables fetching Git submodules |
| of a project from server. |
| |
| The -c/--current-branch option can be used to only fetch objects that |
| are on the branch specified by a project's revision. |
| |
| The --optimized-fetch option can be used to only fetch projects that |
| are fixed to a sha1 revision if the sha1 revision does not already |
| exist locally. |
| |
| SSH Connections |
| --------------- |
| |
| If at least one project remote URL uses an SSH connection (ssh://, |
| git+ssh://, or user@host:path syntax) repo will automatically |
| enable the SSH ControlMaster option when connecting to that host. |
| This feature permits other projects in the same '%prog' session to |
| reuse the same SSH tunnel, saving connection setup overheads. |
| |
| To disable this behavior on UNIX platforms, set the GIT_SSH |
| environment variable to 'ssh'. For example: |
| |
| export GIT_SSH=ssh |
| %prog |
| |
| Compatibility |
| ~~~~~~~~~~~~~ |
| |
| This feature is automatically disabled on Windows, due to the lack |
| of UNIX domain socket support. |
| |
| This feature is not compatible with url.insteadof rewrites in the |
| user's ~/.gitconfig. '%prog' is currently not able to perform the |
| rewrite early enough to establish the ControlMaster tunnel. |
| |
| If the remote SSH daemon is Gerrit Code Review, version 2.0.10 or |
| later is required to fix a server side protocol bug. |
