Features

1. Checks buildouts ``[versions]`` sections while stepping through the cascaded extends

   • command line script collects the inherited version pins, remembers where a version pin comes from.

   • It displays the result in order to enable a human to check pins and overrides are ok.

   • Output is colored, this helps to identify packages which have newer versions available.

   • Machine readable output as JSON on demand.

2. Checks Python Package Index (PyPI) for newer versions.

   • Detects if a newer major, minor or bugfix (or a prerelease) is available.

3. Buildout extension records the current versions state and requirements

   • versions state and requirements are written to a file,

   • versions from the file will be consumed by the command line tool

     • orphaned version pin are detected,

     • it shows by whom as dependency a package was demanded.

It works best with semantically and only with syntactically correct version numbers!

Usage

Install with your buildout

Add a section to install it as a script and add it as an extension to your builodut:

[buildout]
...
extensions =
    plone.versioncheck

parts =
    ...
    ploneversioncheck
    ...

...

[ploneversioncheck]
recipe = zc.recipe.egg
eggs = plone.versioncheck

...

Run buildout as usal.

Now a file .plone.versioncheck.tracked.json was generated in the buildout-directory.

This file will be used by bin/versioncheck to figure out which packages were finally used.

Run buildout again to regenerate this file.

commandline

usage: versioncheck [-h] [-p] [-n] [-r] [-i] [-m] [--no-cache] [--no-colors]
                    [--debug-limit DEBUG_LIMIT]
                    [buildout]

Fetch information about pinned versions and its overrides insimple and complex/cascaded buildouts.

positional arguments:
  buildout              path to buildout.cfg or other *.cfg file

optional arguments:
  -h, --help            show this help message and exit
  -p, --pypi            check pypi for newer versions
  -n, --newer           display only packages with newer version than active
  -r, --required-by     show information about requirements (only if tracking
                        file is available)
  -i, --ignore-tracking
                        ignore tracking file (if present)
  -m, --machine         show as machine readable output (json)
  --no-cache            do not use a cache for pypi/ external buildout configuration files
  --no-colors           do not show colors
  --debug-limit DEBUG_LIMIT
                        Limit the number of pypi versions fetched for
                        debugging

[...]

Files created

If the script was used with --pypi option a directory .plone.versioncheck.cache will be created. It contains the cache of the requests to PyPI or external buildout configuration files. To clear the cache remove the directory. The caching library uses the expiration headers of the response from PyPI, so even with cache it starts fetching new records.

If extension was used a file .plone.versioncheck.tracked.json will be created. It contains the information from last buildout run.

Output explained

Legend of states and colors

[D]evelopmen Egg

A development egg is usally active. Description show location. Color: Green

[A]ctive Pin

Pinned version. Package is used and recent, all seems fine. Color: White

[I]nherited Pin

unused pin. If older than active pin color is gray, if newer yellow.

[O]rphaned

If tracked, it shows if the package in the given configuration was used at all. Be careful with this information! I.e. in a development buildout file other packages are used than in a live or continious integration buildout! Color: Magenta

[X] Unpinnend

Tracked, but no pin in versions sections were found. Color: Red

[U]pdate final release

At PyPI there is a newer final version available (major, minor or bugfix). Descriptions shows on which level. Color: Cyan

[P]rerelease update

At PyPI there is a newer prerelease version available (major, minor or bugfix). Descriptions shows on which level. Only if there is no final release updatye available. Color: Blue

[R] Required by

If tracked and option --required-by was given, show packages this package is required by. Valid for current active/ used version. Keep in mind this is based on the declared requirements, missing or implicit requirements are not covered.

Order of versions

Order of versions is the buildout resolution order (how they are resolved by buildout in the extends chain/tree). After that the PyPI releases are shown (major, minor, pre, then the prereleases)

Example, given in each a version of my.pkg was declared

1. buildout.cfg with my.pkg=3.0.3

   1. buildout.cfg extends foo.cfg with my.pkg=3.0.1

   2. buildout.cfg extends bar.cfg with my.pkg=2.0

      2. foo cfg extends baz.cfg with my.pkg=3.1

2. found a newer versions at pypi

   1. major my.pkg=4.0

   2. minor my.pkg=3.2

   3. major prerelease my.pkg=5.1b2

Output looks like so:

my.pkg
    3.0.3............... A buildout.cfg
    2.0 ................ I bar.cfg
    3.0.1 .............. I foo.cfg
    3.1 ................ I baz.cfg
    4.0 ................ U Major
    3.2 ................ U Minor
    5.1b2............... P Majorpre
