When there are nested projects in a manifest, like on AOSP right now: <project path="build" name="platform/build" /> <project path="build/blueprint" name="platform/build/blueprint" /> <project path="build/kati" name="platform/build/kati" /> <project path="build/soong" name="platform/build/soong" /> And the top "build" project is removed (or renamed to remove the nesting), repo just wipes away everything under build/ and re-creates the projects that are still there. But it only checks to see if the build/ project is dirty, so if there are dirty files in a nested project, they'll just be blown away, and a fresh worktree checked out. Instead, behave similarly to how `git clean -dxf` behaves and preserve any subdirectories that have git repositories in them. This isn't as strict as git -- it does not check to see if the '.git' entry is a readable gitdir, just whether an entry named '.git' exists. If it encounters any errors removing files, we'll print them all out to stderr and tell the user that we were unable to clean up the obsolete project, that they should clean it up manually, then sync again.

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.
|
|
|
|
The --prune option can be used to remove any refs that no longer
|
|
exist on the remote.
|
|
|
|
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.
