Eve

I was lucky enough be the first guest for the shiny new Talk Python To Me Podcast hosted by Michael Kennedy. In this episode we talk about Eve an my other open source releases, which gives us an excuse to touch on a variety of topics such as Polyglot Programming, New Microsoft and the .NET evolution, MongoDB and the Open Source eco-system as seen from the point of view of an old fart who has been spending most of his career in closed systems. ...

Yesterday Cerberus 0.8.1 was released with a few little fixes, one of them being more a new feature than a fix really: sub-document fields can now be set as field dependencies by using a ‘dotted’ notation. So, suppose we set the following validation schema: schema = { 'test_field': { 'dependencies': [ 'a_dict.foo', 'a_dict.bar' ] }, 'a_dict': { 'type': 'dict', 'schema': { 'foo': {'type': 'string'}, 'bar': {'type': 'string'} } } } Then, we can validate a document like this: ...

Eve 0.5.2 has just been released with a bunch of interesting fixes and documentation updates. See the changelog for details.

Flask-Sentinel is a OAuth2 Server implementation of the Resource Owner Password Credentials Grant pattern described in Section 1.3.3 of RFC 6749. It is powered by Flask-Oauthlib, Redis and MongoDB and is bundled as a Flask extension so it can be used to add OAuth2 capabilities to an existing application. So what is the Resource Owner Password Credentials Grant pattern? According to the official RFC: The resource owner password credentials (i.e., username and password) can be used directly as an authorization grant to obtain an access token. The credentials should only be used when there is a high degree of trust between the resource owner and the client (e.g., the client is part of the device operating system or a highly privileged application). ...

Eve 0.5.1 was just released with a couple fixes to 0.5 (which was released earlier this week.) Don’t be surprised. Going forward I’m striving for a much faster release cycle, especially so when it comes to fixes.

Powered by SQLAlchemy and good intentions, Eve-SQLAlchemy is an official Eve extension which allows to effortlessly build and deploy highly customizable, fully featured RESTful Web Services with SQL backends. As with all Eve extensions, once installed with $ pip install eve-sqlalchemy using Eve-SQLAlchemy is very simple: from eve import Eve from eve_sqlalchemy import SQL app = Eve(data=SQL) app.run() On a fresh virtualenv (of course you are using virtualenvs, right?) the install will also setup Eve and all its dependencies for you. For a complete tutorial you can visit the Eve-SQLAlchemy Support Website. ...

Eve v0.5 was released today. Cerberus v0.8 only a few days ago. A whole lot of new features, changes and fixes are coming with these releases so make sure to check the official release post to gather all the news.

A lot of servers have been including a JeSuisCharlie header with their responses. If you haven’t already, try with Charlie Hebdo site itself: $ curl -I charliehebdo.fr Date: Mon, 12 Jan 2015 15:56:13 GMT Content-Type: text/html; charset=iso-8859-1 Content-Length: 221 Connection: keep-alive Location: http://www.charliehebdo.fr/index.html Vary: Accept-Encoding X-Charlie-fr: Je suis toujours Charlie. X-Charlie-en: I am still Charlie. X-Charlie-es: Todavia soy Charlie. X-Charlie-de: Ich bin immer Charlie. X-Charlie-ro: Inca sunt Charlie. X-Charlie-cz: Jsem stale Charlie. I find this to be a great way for us techies to somehow contribute and show support for the ongoing anti-terrorism campaign. So if you feel like doing it here is a quick rundown on how to serve custom headers with your Eve-powered REST API. It is actually a very easy task to accomplish. ...

Eve.NET is a simple HTTP and REST client for Web Services powered by the Eve Framework. It leverages both System.Net.HttpClient and Json.NET to provide the best possible Eve experience on the .NET platform. Written and maintained by the same author of the Eve Framework itself, Eve.NET is delivered as a portable library (PCL) and runs seamlessly on .NET4, Mono, Xamarin.iOS, Xamarin.Android, Windows Phone 8 and Windows 8. We use Eve.NET internally to power our iOS, Web and Windows applications. ...

Last week I was speaking at an Open Source panel at Better Software 2014, and one of the topics that we touched was code responsibility. This is an important topic for anyone who is maintaining an open source project, especially when it comes to the process of reviewing and accepting code contributions. At some point during the debate, I argued that when a maintainer merges a pull request, he (or she) implicitly agrees on being responsible for that code. That seemed to strike some surprise into most attendees. Yes, in theory any contributor is just a ping away so in case trouble arises one can always reach him, or her. Unfortunately this is not always the case. While some contributors will fully embrace your project and keep helping after their initial contribution, truth is that a good number of them will just move on, never to be seen again. There’s nothing wrong with that. Not everyone has spare time to devote to your project, which is perfectly fine. It is natural for most people to contribute what they need to a project and then go on their way. Actually, one could argue that most projects grow and prosper precisely thanks to this kind of contributions. However this attitude can become an incumbent when big chunks of code get merged, usually as new (big) features. Good practices advice against merging huge pull requests. In fact they are rare and when they do come, it is a good idea to ask for them to be split into smaller ones. But no matter the format, a huge contribution is likely to hit a project one day or another. It might even come from more than one person: a disconnected and distributed team of contributors who have been patiently tinkering on a side branch or a fork for example. When this happens, and provided that the contribution is worth merging, the maintainer should then ask him/herself the obvious question: am I willing to deal with the consequences of this merge? ...
