================================== Corduroy · asynchronous upholstery ================================== :project: http://samizdat.cc/corduroy :code: http://github.com/samizdatco/corduroy About ===== Corduroy provides a python-friendly wrapper around CouchDB’s HTTP-based API. Behind the scenes it hooks into the asynchronous i/o routines from your choice of `Tornado <http://www.tornadoweb.org/>`_ or the `Requests <http://docs.python-requests.org/>`_ & `Gevent <http://gevent.org/>`_ modules. Using corduroy you can query the database without blocking your server’s event loop, making it ideal for `CouchApp <http://couchapp.org/page/index>`_ micro-middleware or scripted batch operations. Usage ===== As a real world(ish) example of working with Corduroy, consider this pair of Tornado event handlers which update a url-specifed document then query a view. The first uses explicit callbacks to resume execution after each response from the database is received:: db = Database('players') class RankingsUpdater(tornado.web.RequestHandler): @tornado.web.asynchronous def post(self, player_id): self.new_score = int(self.request.body) db.get(player_id, callback=self.got_player) def got_player(doc, status): doc.score = self.new_score db.save(doc, callback=self.saved_player) def saved_player(conflicts, status): db.view('leaderboard/highscores', callback=self.got_highscores) def got_highscores(rows, status): self.write(json.dumps(rows)) self.finish() An alternative syntax is available (when using Tornado) through the use of the @relax decorator. Instead of defining callbacks for each database operation, the library can be called as part of a yield expression. Tornado’s `generator <http://www.tornadoweb.org/documentation/gen.html>`_ module will intercept these yields and provide a callback automatically. The result is code that looks quite sequential but will still execute asyncronously:: class RankingsUpdater(tornado.web.RequestHandler): @relax def post(self, player_id): # update this player's score doc = yield db.get(player_id) doc.score = int(self.request.body) yield db.save(doc) # return the new rankings highscores = yield db.view('leaderboard/highscores') self.write(json.dumps(highscores)) self.finish() For a gentle introduction to Corduroy (and CouchDB in general), take a look at the `Guide <http://samizdat.cc/corduroy/guide/>`_. Documentation for all of Corduroy’s module-level classes can be found in the `Reference <http://samizdat.cc/corduroy/ref>`_ section. Installation ============ Automatic Installation ---------------------- Corduroy can be found on PyPi and can be installed with your choice of pip or easy_install. Manual Installation ------------------- Download `corduroy-0.9.0.tar.gz <http://samizdat.cc/corduroy/dist/corduroy-0.9.0.tar.gz>`_:: tar xvzf corduroy-0.9.0.tar.gz cd corduroy-0.9.0 python setup.py install Dependencies ------------ If you’re writing a Tornado app, Corduroy can use its pure-python HTTP client by installing with:: pip install corduroy tornado Or if you’d prefer the libcurl-based client (which supports pooling and other niceties), use:: pip install corduroy tornado pycurl If pycurl complains (I’m looking at you, OS X), try:: env ARCHFLAGS="-arch x86_64" pip install pycurl Gevent users can install with:: pip install corduroy requests gevent The library can also be used with plain-old blocking i/o:: pip install corduroy requests License ======= Corduroy is released under the BSD license. Use it freely and in good health. Acknowledgments =============== Corduroy is derived from Christopher Lenz’s excellent `couchdb-python <http://code.google.com/p/couchdb-python>`_ module and inherits much of its API (and most of its test cases) from that codebase. It is also indebted to Eric Naeseth’s mind-expanding `Swirl <http://code.naeseth.com/swirl/>`_ library which first acquainted me with the idea of using generators to simulate sequential code.
