Use json as the output format and only use stderr for when the multipip program really fails. Instead of outputting to the screen all incompatible errors just output the incompatible versions to the output json data structure and use this in the main anvil program. Use defaultdict + list in multipip where appropriate. Ensure that as documented we select the first matching requirement that comes out of multipip instead of the last (when incompat. matches happen). Adjust documentation for new json output format.

|
multipip
|
|
--------
|
|
|
|
`pip` utility refuses to handle multiple requirements for one package::
|
|
|
|
$ pip install 'nose>=1.2' 'nose>=2' 'nose<4'
|
|
Double requirement given: nose>=2 (already in nose>=1.2, name='nose')
|
|
|
|
Use `multipip` to join these requirements::
|
|
|
|
$ multipip 'nose>=1.2' 'nose>=2' 'nose<4'
|
|
{"compatibles": ["nose>=2,<4"], "incompatibles": {}}
|
|
|
|
Files of requirements can be used as well::
|
|
|
|
$ cat pip-requires
|
|
nose<4
|
|
$ multipip 'nose>=1.2' 'nose>=2' -r pip-requires
|
|
{"compatibles": ["nose>=2,<4"], "incompatibles": {}}
|
|
|
|
`multipip` prints error messages for badly formated requirements and exits early
|
|
and for incompatible requirements provides you which package was incompatible
|
|
and which versions were found to be problematic::
|
|
|
|
$ cat pip-requires
|
|
pip==1.3
|
|
$ multipip 'pip==1.2' -r pip-requires
|
|
{"compatibles": [], "incompatibles": {"pip": ["pip==1.2", "pip==1.3"]}}
|
|
|
|
It is possible to filter some packages from printed output. This can
|
|
be useful for a huge `pip-requires` file::
|
|
|
|
$ cat pip-requires
|
|
nose<4
|
|
pip==1.2
|
|
nose>=1.2
|
|
$ multipip -r pip-requires --ignore-packages nose
|
|
{"compatibles": ["pip==1.2"], "incompatibles": {}}
|
|
|
|
Installed packages can be filtered, too (they are taken from `pip
|
|
freeze`)::
|
|
|
|
$ cat pip-requires
|
|
nose<4
|
|
pip==1.2
|
|
nose>=1.2
|
|
$ pip freeze | grep nose
|
|
nose==1.1.2
|
|
$ multipip -r pip-requires --ignore-installed
|
|
{"compatibles": ["pip==1.2"], "incompatibles": {}}
|
|
|
|
py2rpm
|
|
------
|
|
|
|
Distutils provides an interface for building RPMs::
|
|
|
|
$ python ./setup.py bdist_rpm
|
|
|
|
This tool has several problems:
|
|
|
|
* Red Hat based distros use different package names, e.g.,
|
|
`python-setuptools` instead of `distribute`, `python-nose` instead
|
|
of `nose` and so on...
|
|
* `Requires` and `Conflicts` sections for generated RPM are incorrect.
|
|
* Sometimes not all required files are packaged.
|
|
* Miscellaneous problems with man files;
|
|
* Package directory in `/usr/lib*/python*/site-packages/<pkg>` is not
|
|
owned by any RPM;
|
|
* Some packages (like selenium) are architecture dependent but
|
|
`bdist_rpm` generates `BuildArch: noarch` for them.
|
|
|
|
`py2rpm` is aimed to solve all these problems.
|
|
|
|
`py2rpm` accepts a list of archive names or package directories and
|
|
builds RPMs (current directory is used by default)::
|
|
|
|
$ py2rpm
|
|
...

|
