Murphey had an adage: “Anything that can go wrong, will go wrong.” The best we can do is attempt to anticipate any problems that might come up and keep ‘the machine’ running. From an end-user perspective that means being responsive, even with errors. If there is a network error, we want to know as soon as possible with the guarantee that state of ‘the machine’ was not effected by the error.
We now have per-call deadline and timeouts!
I recently upgraded to Ubuntu 15.10 (Wily Weerwolf) which automatically upgraded VirtualBox from 4.3 to 5.0 and broke compatibility with Vagrant 1.6 in the process. Thinking that Vagrant knows about this and they claim VBox 5.0 compatbility, I upgraded to 1.7 and came across the same error!
There is a workaround!
We’re proud to announce the release of 0.6 of TxMongo, which brings SSL support using Twisted’s SSL context factory, “find with cursor” support just like PyMongo, bug fixes and updated unit tests! TxMongo is an asynchronous MongoDB client written for Twisted in Python.
The biggest change is that TxMongo is now sponsored by Amplidata. Through them we were able to get development, bug fixes and Twisted first-party sponsorship online. We now have continuous integration (CI) with a wide matrix of support for py26/py27/pypy using Twisted 12.1 to 14.0 (and trunk). We also now have 78% code coverage with unit testing as a result!
This is also the very last release in the 0.x series before we step over to the “year.release” model used by Twisted, it will also eventually find its way into Twisted’s github organization as a first class library.
