if a gerrit server has ssh and https access enabled, but user access
(for some users) is limited to https, 'repo upload' command will fail
for them.
Gerrit returns a ssh configuration (gerrit/ssh_info), that does not work
for users limited to https.
With this patch repo will test, if the returned ssh configuration from
gerrit/ssh_info is working. if not, it will fall back to https for upload.

As an alias for the local repository, remote '.' is lacking a fetch =

local tracking branch.

An HTTP (or HTTPS) based remote server may now offer a 'clone.bundle'
file in each repository's Git directory. Over an http:// or https://
remote repo will first ask for '$URL/clone.bundle', and if present
download this to bootstrap the local client, rather than relying
on the native Git transport to initialize the new repository.
Bundles may be hosted elsewhere. The client automatically follows a
HTTP 302 redirect to acquire the bundle file. This allows servers
to direct clients to cached copies residing on content delivery
networks, where the bundle may be closer to the end-user.
Bundle downloads are resumeable from where they last left off,
allowing clients to initialize large repositories even when the
connection gets interrupted.
If a bundle does not exist for a repository (a HTTP 404 response
code is returned for '$URL/clone.bundle'), the native Git transport
is used instead. If the client is performing a shallow sync, the
bundle transport is not used, as there is no way to embed shallow
data into the bundle.

If the SSH control master process is killed while an active git
fetch is using its network socket, the underlying SSH client may
not realize the connection was broken. This can lead to both the
client and the server waiting indefinitely for network messages
which will never be sent.
Work around the problem by keeping track of any processes that use
the tunnels we establish. If we are about to kill any of the SSH
control masters that we started, ensure the clients using them are
successfully killed first.

than we can fork+exec the git config process.
If the corresponding git config file has a newer modification
timestamp than the pickle file, we delete the pickle file and
regenerate it. This ensures that any edits made by the user

The mirror option downloads a complete forrest (as described by the

than a client working directory. This permits other clients to

A mirror can be positioned in a "DMZ", where the mirror executes
"repo sync" to obtain changes from the external upstream and
clients inside the protected zone operate off the mirror only,
and therefore do not require direct git:// access to the external
