This would, as described above, create the packages diffimg-8.0.28+3E, coreUtils-0.5.2+5E, psycopg2-2.4.6+5E, cxOracle-5.1.2+9E.
Typically, The package diffimg-8.0.28+3E would then be the package to test and play around with.
Create Operational Package Version associated with the Experimental Package Version
To be written.
Possibly, once all the tests have successfully been concluded, you would like to create an operational version from that. Currently, the suggested way to do that is to again run the package propagator by using exactly the same parameters as above - but by setting an additional --operational flag:
| No Format |
|---|
$ pkg_propagator --replace python-2.7.6+1 --by python-2.7.7+0 --reference diffimg-8.0.28+2 --operational |
This would propose to create new packages diffimg-8.0.28+4, coreUtils-0.5.2+6, psycopg2-2.4.6+6, cxOracle-5.1.2+10 - as long as no other package versions have been added for the given product versions (diffimg-8.0.28, coreUtils-0.5.2, psycopg2-2.4.6, cxOracle-5.1.2) in the meantime.
In the future, we may simplify that - e.g. by a command of the form
pkg_propagator diffimg-8.0.28+3E --operationalwhich would actually create new package versions diffimg-8.0.28+3, coreUtils-0.5.2+5, psycopg2-2.4.6+5, cxOracle-5.1.2+9 (obtained from the experimental versions by removing the 'E'). in any case, the experimental version will remain in the system.
Known Issues
- Currently, only one single dependency can be replaced at the time. Work in progress to replace multiple packages at the same time.
- No transaction handling: The propagator interacts with both, the continuous integration build system (for fetching the information which packages to create) and SVN for the checkout and the commit. The continuous build system needs some time to update its state for SVN changes (at the order of 30-60 secs) so that SVN and continuous integration build system are not guaranteed to always by concurrent. As a result, users may experience problems when submitting proposed changes - e.g. when two users want to do the same thing at the same time.
