# Customizing your PyPI or Anaconda repository mirror - v 2.2.0 or earlier (AER 2.24)

Although some aspects of mirroring PyPI and the Anaconda repository differ, the methodology for the specification of which packages to mirror is identical. You can specify:

- platforms (valid options are: ‘linux-64’, ‘linux-32’, ‘osx-64’, ‘win-32’, and ‘win-64’)
- whitelist
- blacklist
- license_blacklist (the only valid option at this time is ‘GPL’)

All specification information should be included in the same file, and can be passed to the binstar-sync-pypi or binstar-sync-conda command via the –mirror-config argument:

    binstar-sync-conda --mirror-config /etc/binstar/mirrors/conda.yaml
    binstar-sync-pypi --mirror-config /etc/binstar/mirrors/pypi.yaml

## Platform-specific mirroring

By default, the binstar-sync-pypi and binstar-sync-conda tools will mirror all platforms. If you know that you will not need every platform, you will find it useful to save time and space by editing the sync-configuration.txt file to specify the platform(s) you want mirrored:

    platforms:
      - linux-64
      - win-32

## “Whitelist” Mirroring

If your .yaml file contains a ‘whitelist’ argument, only the packages enumerated under whitelist will be synced to your repository.

The file must contain a newline separated list of packages:

    whitelist:
      - dnspython
      - shapely
      - gdal

## “Blacklist” Mirroring

Although the whitelist is an inclusive delineation, the blacklist functions as an exclusive delineation. For example:

    blacklist:
      - bzip2
      - tk
      - openssl

...will have the effect of mirroring the entire Anaconda repository except the bzip2, tk, and openssl packages.

## “License Blacklist” Mirroring

Currently, only blacklisting GPL packages is supported:

    license_blacklist:
      - GPL

In this example, the mirror will copy all the packages in the repository except those which are GPL-licensed, because the entire GPL license has been license_blacklisted.

## Combining Multiple Mirror Configurations

In some situations, you may find that combining two or more of the arguments above is the simplest way to get exactly the packages you want.

The platform argument is evaluated before whitelist, blacklist or license_blacklist arguments. For example:

    platforms:
      - linux-64
    whitelist:
      - dnspython
      - shapely
      - gdal

...would have the effect of mirroring ONLY linux-64 distributions of the dnspython, shapely and gdal packages.

The combination of both whitelist and blacklist functionality is an unlikely scenario, because their impact is complementary. It is recommended that you employ the argument that requires the enumeration of the least number of packages. Use whitelist if you want to install fewer than half the packages in the repository, and blacklist if you want to install more than half the total packages.

If the whitelist and license_blacklist arguments are both employed, the license_blacklist will be evaluated first, with the whitelist functioning as a modifier. In this way packages which have been initially blacklisted can be added back in.:

    license_blacklist:
      - GPL
    whitelist:
      - pyqt

This mirror configuration will copy ALL packages in the repository, except those that are GPL-licensed, and will subsequently copy PyQt, despite its GPL license, because it has been whitelisted.
