buildout.sendpickedversions 0.3

Sends picked packages and versions to a whiskers server.

buildout.sendpickedversions

This package is based on buildout.dumppickedversions and its purpose is to gather the package name and version information from buildout. The main difference with buildout.dumppickedversions is that instead of displaying picked versions, or dumping everything to a file, we’ll send package information to a predefined URL.

Original use case is that there is Whiskers server on the other end which stores the data. There’s nothing special about the data, so other end can just as well be anything that can handle json.

Configuration

To use buildout.sendpickedversions with buildout your buildout.cfg should have buildout.sendpickedversions in you extensions-line and following fields configured:

buildoutname

This is the name of the buildout. Whiskers uses this information to create new buildout object with the package data. If name is not set we use default ‘dummy_buildout’ as a name.

whiskers-url

This is the url to whiskers server. As stated above, you can use here anything that can just eat the json-data we’re sending. If you leave this empty or don’t set at all buildout.sendpickedversions just displays the data dict.

Example

Here’s small example configuration.

[buildout]
extensions = buildout.sendpickedversions
buildoutname = test
whiskers-url = http://localhost:6543/buildouts/add

parts = nose

[nose]
recipe = zc.recipe.egg
eggs = nose

Above example configuration assumes you have Whiskers server running locally on port 6543. If you run buildout it will install nose normally to your buildout environment and after everything is ready it will try to send following data in json-format to localhost:6543/buildouts/add URL:

{"buildoutname": "test",
 "packages": [
    {"version": "0.6.24", "name": "distribute"},
    {"version": "1.18", "name": "mr.developer"},
    {"version": "1.1.2", "name": "nose"},
    {"required_by": ["mr.developer 1.18"], "version": "1.5.2", "name": "zc.buildout"},
    {"version": "1.3.2", "name": "zc.recipe.egg"}
  ]
}

Thanks

Code is mainly based to Mustapha Benali’s buildout.dumppickedversions. This buildout extension has probably saved thousands of buildouts from nasty version conflicts or total havoc. Huge thanks!
