83The '%prog' command synchronizes local project directories
84with the remote repositories specified in the manifest. If a local
85project does not yet exist, it will clone a new local directory from
86the remote repository and set up tracking branches as specified in
87the manifest. If the local project already exists, '%prog'
88will update the remote branches and rebase any new local changes
89on top of the new remote changes.
90
91'%prog' will synchronize all projects listed at the command
92line. Projects can be specified either by name, or by a relative
93or absolute path to the project's local directory. If no projects
94are specified, '%prog' will synchronize all projects listed in
95the manifest.
Shawn O. Pearce3e768c92009-04-10 16:59:36 -070096
97The -d/--detach option can be used to switch specified projects
98back to the manifest revision. This option is especially helpful
99if the project is currently on a topic branch, but the manifest
100revision is temporarily needed.
Shawn O. Pearceeb7af872009-04-21 08:02:04 -0700101
Nico Sallembiena1bfd2c2010-04-06 10:40:01 -0700102The -s/--smart-sync option can be used to sync to a known good
103build as specified by the manifest-server element in the current
Victor Boivie08c880d2011-04-19 10:32:52 +0200104manifest. The -t/--smart-tag option is similar and allows you to
105specify a custom tag/label.
Nico Sallembiena1bfd2c2010-04-06 10:40:01 -0700106
David Pursehousecf76b1b2012-09-14 10:31:42 +0900107The -u/--manifest-server-username and -p/--manifest-server-password
108options can be used to specify a username and password to authenticate
109with the manifest server when using the -s or -t option.
110
111If -u and -p are not specified when using the -s or -t option, '%prog'
112will attempt to read authentication credentials for the manifest server
113from the user's .netrc file.
114
115'%prog' will not use authentication credentials from -u/-p or .netrc
116if the manifest server specified in the manifest file already includes
117credentials.
118
Andrei Warkentin5df6de02010-07-02 17:58:31 -0500119The -f/--force-broken option can be used to proceed with syncing
120other projects if a project sync fails.
121
Shawn O. Pearcee02ac0a2012-03-14 15:36:59 -0700122The --no-clone-bundle option disables any attempt to use
123$URL/clone.bundle to bootstrap a new Git repository from a
124resumeable bundle file on a content delivery network. This
125may be necessary if there are problems with the local Python
126HTTP client or proxy configuration, but the Git binary works.
127
Che-Liang Chioub2bd91c2012-01-11 11:28:42 +0800128The --fetch-submodules option enables fetching Git submodules
129of a project from server.
130
Shawn O. Pearceeb7af872009-04-21 08:02:04 -0700131SSH Connections
132---------------
133
134If at least one project remote URL uses an SSH connection (ssh://,
135git+ssh://, or user@host:path syntax) repo will automatically
136enable the SSH ControlMaster option when connecting to that host.
137This feature permits other projects in the same '%prog' session to
138reuse the same SSH tunnel, saving connection setup overheads.
139
140To disable this behavior on UNIX platforms, set the GIT_SSH
141environment variable to 'ssh'. For example:
142
143 export GIT_SSH=ssh
144 %prog
145
146Compatibility
147~~~~~~~~~~~~~
148
149This feature is automatically disabled on Windows, due to the lack
150of UNIX domain socket support.
151
152This feature is not compatible with url.insteadof rewrites in the
153user's ~/.gitconfig. '%prog' is currently not able to perform the
154rewrite early enough to establish the ControlMaster tunnel.
155
156If the remote SSH daemon is Gerrit Code Review, version 2.0.10 or
157later is required to fix a server side protocol bug.
