Module command 

The command list: <old-oid> <new-oid> <refname>, written by the client and read by the server.

Reference names are bytes

refs/heads/\xff is a name git will create, advertise and serve, so PushCommand::name is a BString and parse_line splits on bytes.

Routing the line through String::from_utf8_lossy first — which is what a String field forces — replaces every invalid byte with U+FFFD before the name is validated. A non-UTF-8 name is then accepted and stored under a name the client never asked for, and any two names differing only in their invalid bytes collapse onto the same reference, so a push to one silently overwrites the other. That was a real bug in gunnar’s server. The lossy rendering survives only in the error messages here, where it is read by a human and not by a store.

Structs

PushCommand

One line of the command list: move name from old to new.

Constants

SHALLOW_PREFIX

A shallow <oid> line, which a shallow client sends before its commands and which is not a command.

Functions

lines

Render the command list as payload lines, without pkt-line framing, without the terminating flush-pkt and without the trailing newline: the caller owns the framer.

parse_line

Parse one command line, having already had its capability suffix removed by capabilities::split.

push_option_lines

Render the push-options section as payload lines.
