Acceptance criteria for external software

As a general recommendation, the number of external software dependencies should be limited as much as possible. Introducing any external software should be carefully evaluated BEFORE starting any development. The final agreement should be given by the EMT by submitting a request describing

  • use case
  • description
  • download location
  • commenting the individual acceptance criteria

Enough time (in general two weeks) should be given to the integration team as well as by the other software clusters to evaluate the addition.

Uniqueness of functionality

A new 3rd party software should be only introduced if a similar functionality is not already provided by an already existing 3rd party software used within the gLite software stack or by the gLite software stack itself.

Usage of standard solution

As much as possible standard/widely accepted 3rd party software should be used in order to be in line with other software projects and developments.

Non-introduction of incompatibilities

The introduction of a new 3rd party software should not introduce any incompatibilities for other parts of the gLite software stack.

Minimize impact

The impact of the introduction of a new 3rd party software should be evaluated in terms of size and functionality. This concerns e.g. cases where only a small functionality of the new software is used while a huge (set of) libraries needs to be included.

Multi-platform support

The 3rd party software must be available and supported on all gLite targeted platforms. For the moment the main gLite target platforms are SL(C)3 and SL(C)4.

Stable version

The 3rd party software used for the gLite software must be a stable, released version and must not be a beta or development version.


The license of the external software must not contradict the gLite software. Software needed to run gLite must be freely downloadable for all users. Preference should be given to freely distributable software and any exception to this should be carefully decided.


All 3rd party software the gLite software stack is using must be secure i.e there have been no published security vulnerabilities in any of them that have not been fixed in the versions gLite is using.
