This version (0+20140207+git18be5c2-2) of JediHTTP
(/usr/lib/vim-youcompleteme/ycm/server/) does not include the HMAC
mechanism. Each vim instance starts a HTTP proxy to Jedi to which
anybody on localhost can connect via TCP. Tested with Python files with
youcompleteme enabled.
For example one can run the following command as another user (httpie
for ease):
$ http -v POST 127.0.0.1:${port}/user_options @/tmp/default_settings.json
/tmp/default_settings.json based on
/usr/lib/vim-youcompleteme/ycm/server/default_settings.json.
You can change min_num_of_chars_for_completion to quickly prove that
settings have been updated.
One can also run arbitrary commands on behalf of the user. Just set
global_ycm_extra_conf to a path to a Python file and wait for the user
to exit vim.
