Joris Vink 0bf36b763a add new python-pgsql example 2017-02-06 11:51:49 +01:00
Joris Vink ace8c4e80c Add asynchronous pgsql query support to python. 
This commit adds the ability to use python "await" to suspend
execution of your page handler until the query sent to postgresql
has returned a result.

This is built upon the existing asynchrous query framework Kore had.

With this you can now write stuff like:

async def page(req):
	result = await req.pgsql("db", "SELECT name FROM table");
	req.response(200, json.dumps(result).encode("utf-8"))

The above code will fire off a query and suspend itself so Kore can
take care of business as usual until the query is successful at which
point Kore will jump back into the handler and resume.

This does not use threading, it's purely based on Python's excellent
coroutines and generators and Kore its built-in pgsql support.

Joris Vink 80698ee40a add kore_mem_cleanup() to cleanup pools at exit. 2017-02-06 11:42:23 +01:00
Joris Vink de7a6d4855 pgsql improvements. 
- adds new cleanup function that workers will call.
- adds kore_pgsql_nfields() to return number of fields in result.
- add kore_pgsql_fieldname() to return name of a given field.

This commit also changes the behaviour of pgsql_conn_release() in
that it will now cancel the active query before releasing the connection.

This makes sure that if long running queries are active they are hopefully
cancelled if an http request is removed while such queries are still running.

Renamed both of them:

These functions will now always be called if they are defined in any module
regardless of your application being built as a single binary or not.
