b.t.r.RemoteHTTPTransport(RemoteTransport) : class documentation

Part of bzrlib.transport.remote View In Hierarchy

Just a way to connect between a bzr+http:// url and http://.

This connection operates slightly differently than the RemoteSSHTransport. It uses a plain http:// transport underneath, which defines what remote .bzr/smart URL we are connected to. From there, all paths that are sent are sent as relative paths, this way, the remote side can properly de-reference them, since it is likely doing rewrite rules to translate an HTTP path into a local path.

Method __init__ Constructor.
Method clone Make a new RemoteHTTPTransport related to me.
Method _build_medium Create the medium if _from_transport does not provide one.
Method _remote_path After connecting, HTTP Transport only deals in relative URLs.

Method get_multi Get a list of file-like objects, one for each entry in relpaths.
Method mkdir_multi Create a group of directories
Method append_multi Append the text in each file-like or string object to
Method copy Copy the item at rel_from to the location at rel_to.

Method move_multi Move a bunch of entries.
Method move_multi_to Move a bunch of entries to a single location.
Method delete_multi Queue up a bunch of deletes to be done.

Method __repr__ Undocumented
Method stat_multi Stat multiple files and return the information.
Method readlink Return a string representing the path to which the symbolic link points.
Method hardlink Create a hardlink pointing to source named link_name.
Method symlink Create a symlink pointing to source named link_name.
Method lock_read Lock the given file for shared (read) access.
Method lock_write Lock the given file for exclusive (write) access.

Method _update_pb Update the progress bar based on the current count
Method _iterate_over Iterate over all entries in multi, passing them to func,
Method _seek_and_read An implementation of readv that uses fp.seek and fp.read.
Method _sort_expand_and_combine Helper for readv.
Static Method _coalesce_offsets Yield coalesced offsets.
Method _can_roundtrip_unix_modebits Return true if this transport can store and retrieve unix modebits.
def __init__(self, base, _from_transport=None, http_transport=None):
Constructor.
Parameters_from_transportAnother RemoteTransport instance that this one is being cloned from. Attributes such as the medium will be reused.
mediumThe medium to use for this RemoteTransport. If None, the medium from the _from_transport is shared. If both this and _from_transport are None, a new medium will be built. _from_transport and medium cannot both be specified.
_clientOverride the _SmartClient used by this transport. This should only be used for testing purposes; normally this is determined from the medium.
def _build_medium(self):
Create the medium if _from_transport does not provide one.

The medium is analogous to the connection for ConnectedTransport: it allows connection sharing.

def _remote_path(self, relpath):
After connecting, HTTP Transport only deals in relative URLs.
def clone(self, relative_url):
Make a new RemoteHTTPTransport related to me.

This is re-implemented rather than using the default RemoteTransport.clone() because we must be careful about the underlying http transport.

Also, the cloned smart transport will POST to the same .bzr/smart location as this transport (although obviously the relative paths in the smart requests may be different). This is so that the server doesn't have to handle .bzr/smart requests at arbitrary places inside .bzr directories, just at the initial URL the user uses.
