Another stable release of the mgo Go driver for MongoDB hits the shelves, and this one brings some important improvements and fixes. As usual, it also remains fully compatible with prior releases in the v2 series.

Please read along for the complete list of changes.


New read preference modes

In addition to the traditional Strong, Monotonic, and Eventual modes, the driver now supports all read preference modes defined by the MongoDB specification:

  • PrimaryMode – Talk only to the replica set primary. That’s the same as mgo.Strong.
  • PrimaryPreferredMode – Talk to one of the closest secondaries if the primary is not available.
  • Secondary – Talk to one of the closest replica set secondaries.
  • SecondaryPreferredMode – Talk to the primary if a secondary is not available.
  • NearestMode – Talk to one of the closest servers, whether primary or secondary.

See Session.SetMode for details on how to switch modes.

bson.NewObjectId random initial counter

The bson.NewObjectId method will now uses a random initial counter value, as defined by the specification.

Documentation improvements

Various documentation improvements have been made, as suggested or submitted by contributors.

Bulk API improvements

Several improvements have been made to the Bulk API, including support for update and upsert operations, error reporting improvements, and a more efficient implementation based on write commands where that’s supported (MongoDB 2.6+).

Custom index name support

Indexes created by Collection.EnsureIndex may now declare a custom name during creation, if convenient. The Collection.DropIndexName method was also added to support the dropping of indexes by name.

Collection.Indexes method fixes

The Collection.Indexes method was returning results that lacked some of the information that was input into the Collection.EnsureIndexe method during creation. This has been fixed.

Problem reported by Louisa Berger.

Introduced Index.Minf/Maxf

The Min and Max fields currently offered by the Index type for tuning of geographical indexes were incorrectly assumed to be integers. Unfortunately these types cannot be changed without a backwards incompatible modification, so two new Minf and Maxf fields were introduced with the float64 type. Despite still working, the old fields are now obsolete.

Problem reported by Louisa Berger.

Name resolution fixed for Go 1.5

Go 1.5 modified the behavior of address resolution in a way that breaks the procedure implemented by mgo to resolve names within a given time span. This was addressed and now both IPv4 and IPv6 servers should be working correctly. This change was also applied as a hot fix to the previous release of the driver, to ensure developers could make use of the newly released compiler with mgo.

Issue reported and collaborated around by several contributors.

My first steps into snappifying, I have publish a RestApi for PiGlow (glowapi 0.1.2). I though it might be a good first step and mildly useful for people wanting to set up build notifications, twitter mentions, whatever you fancy!

You can find it in the webdm store…
Code is here: https://code.launchpad.net/~vtuson/+junk/glowapi

And here is how it works:
PiGlow Api exposes PiGlow in your board port 8000, so you can easy accessing by POST in port 8000.

remeber to do the hardware assign, something like: sudo snappy hw-assign glowapi.vtuson /dev/i2c-1

API calls , method POST:

v1/flare
turns all the leds on to max brightness
v1/on
turns all the leds on to med brigthness
v1/clear
turns off all leds
v1/legs/:id
turns all the leds in a leg (:id) to a given brightness
(if not specify it uses a default setting)
parms: intensity , range 0 to 1
eg: http://localhost:8000/v1/legs/1?intensity=0.3
v1/legs/:id/colors/:colid
turns on one led (colid) in a leg (:id) to a given brightness
(if not specify it uses a default setting)
parms: intensity , range 0 to 1
eg: http://localhost:8000/v1/legs/1/colors/green?intensity=0.3
v1/colors/:colid
turn on all leds for a color across all legs
if not specify it uses a default setting)
parms: intensity , range 0 to 1
eg: http://localhost:8000/v1/colors/green?intensity=0.3

ID ranges
legs range : 0 – 2
colors:

I was recently in the situation of wanting to transition traffic gradually from an old deployment to a new deployment. It’s a large production system, so rather than just switching the DNS entries to point at the new deployment, I wanted to be able to shift the traffic over in a couple of controlled steps.

It turns out, Apache’s mod_proxy makes this relatively straight forward. You can choose which resource for which you want to move traffic, and easily update the proportion of traffic for that resource which should go through to the new env. Might be old news to some, but not having needed this before, I was quite impressed by Apache2’s configurability:

# Pass any requests for specific-url through to the balancer (defined below)
# to transition traffic from the old to new system.
ProxyPass /myapp/specific-url/ balancer://transition-traffic/myapp/specific-url/
ProxyPassReverse /myapp/specific-url/ balancer://transition-traffic/myapp/specific-url/

# Send all other requests straight to the backend for the old system.
ProxyPass /myapp/ http://old.backend.ip:1234/myapp/
ProxyPassReverse /myapp/ http://backend.ip:1234/myapp/

# Send 50% of the traffic to the old backend, and divide the rest between the
# two new frontends.
<Proxy balancer://transition-traffic>
    BalancerMember http://old.backend.ip:1234 timeout=60 loadfactor=2
    BalancerMember http://new.frontend1.ip:80 timeout=60 loadfactor=1
    BalancerMember http://new.frontend2.ip:80 timeout=60 loadfactor=1
    ProxySet lbmethod=byrequests
</Proxy>
