uwsgi.send_message does not exist, though API documents it; myadmin script is broken

[gthb]

Based on http://uwsgi-docs.readthedocs.org/en/latest/ManagementFlag.html I just tried to do this:

uwsgi --no-server -w myadmin --pyargv "127.0.0.1:3157 15"

inside the tests directory of the git repo, checked out to the tip of the uwsgi-1.9.18 branch.

But it fails because there is no send_message function in the uwsgi module:

But there should be, according to http://uwsgi-docs.readthedocs.org/en/latest/PythonModule.html

In uwsgi.h there is this declaration:

ssize_t uwsgi_send_message(int, uint8_t, uint8_t, char *, uint16_t, int, ssize_t, int);

... which is then not implemented anywhere.

I added a print statement to dump out sorted(dir(uwsgi)) module:

this has been removed in 1.9 while waiting for a better subsystem (no more based on number-as-key)

Hi,

There used to be set_option in the python module which, albeit complicated, could have had a light idea of setting some options outside of the config file. Now this function is gone. Is it for the same reason as above ?

I'm asking because I want to increase the number of locks on uWSGI. However, I think it would be a good idea to keep it to a minimum (please correct me if I'm wrong). So, in my python app I define which "kind" of locks I want, I assign an id to each, and then I use them. But the number of locks has to be correctly configured with uWSGI, and it could fall out of sync with the defined locks.

I was thinking of doing something like: uwsgi.set_option(locks=len(LockTypes)). Any advice?
