buildout-helpers 1.0.1

Features

• normalize_buildout:

  The tool sorts sections and the keys in each section alphabetically, also some special multi line values, like eggs. sources sections for mister developer get aligned by attributes, so muliple source checkouts with similar branches get identified more easily, because the branch value for each source checkout gets printed in the same column. Some special sections are alwyays at the end or the beginning.

• freeze:

  This tool downloads all buildout configurations and stores them locally. The buildout files get modified to link to the downloaded resources. Every downloaded resource has a header with information that allow freeze to update the resources!

• version_info:

  This tool is similar to the annotate command of buildout. But this tool only gives information about versions. For each package it shows the version buildout will use and what version other buildout files pin. If your buildout file masks newer versions from buildout files it extends, the versions are printed in red. So if you have some version pins and update to a newer Patch version of Plone, you can look for red printouts, these can give you hints to outdated version pins in your own config files.

Detailed features of normalize_buildout

normalize_buildout by default will replace the given config files in place. It buildout files cannot be parsed no file will be modified. It has a command line option for not changing the file and only reporting via exit code if the file is not normalized. This can easily be integrated in check tools or ci tools.

The script understands the special meaning of some sections and keys:

• buildout section is always the first

• versions, and sources section are always the last

• recipe key is always first

• eggs, and zcml values get sorted.

• keys of sources entries get sorted, values get indented so that branch settings are all on the same column.

• mr.developer options are grouped and separated from the other buildout options

Every sorting happens case insensitive. Comments above sections and above keys get shuffled together with key or section. You can document why you need to pin a specific version of a package and after normalization, the comment is still above the right version specifier.

Detailed features of freeze

Freeze downloads all external files to a directory external_buildouts. All buildout files that reference these get their extends values updated to point to the local resources.

Every downloaded resource gets a special header. It warns you to modify the file and it contains the URL from which the resource was downloaded and the ETAG value. Upon repeated invocation, we check, if the resource has actually been changed. So if servers responds with a 304, the resource will not be downloaded again. This is important for heavy CI users, like the quaive project. They sometimes got throttled from github.

Detailed features of version_info

Everything has been said in the general feature section already.

Installation

You can install the package with pip or zc.buildout.

PIP:

$ pip install buildout_helpers

Buildout:

[buildout]

 ...
 [extras]
 recipe = zc.recipe.egg
 eggs =
     buildout_helpers

and then running “bin/buildout”

For use with CI we suggest to use a requirements.txt file with pip to install both buildout_helpers, a defined version of setuptools and zc.buildout.

• Slightly better error handling for normalize_buildout. [do3cc]

• Fixed an error in version info, not handling remote urls properly. [do3cc]

• Fixed an error in version info, extends order was backwards. [do3cc]

• Normalize now sorts case insensitive. [do3cc]

1.0.0b4 (2015-12-14)

• Last release broke, I don’t trust what is as 1.0.0b3 on pypi. [do3cc]

• Sources sections are at the end now [do3cc]
