This is a mechanically generated patch to add a unit test job running under Python 3.6 as part of the python3-first goal. See the python3-first goal document for details: https://governance.openstack.org/tc/goals/stein/python3-first.html Change-Id: I6b493911d950182a9da1e13f01ef22e7bb0516b8 |

Global Requirements for OpenStack Projects
Why Global Requirements?
Refer to the Dependency Management section of the Project Team Guide for information about the history of the project and the files involved.
Tools
All the tools require openstack_requirements to be installed (e.g. in a Python virtualenv). They all have help, which is the authoritative documentation.
update-requirements
This will update the requirements in a project from the global
requirements file found in .. Alternatively, pass
--source to use a different global requirements file:
update-requirements --source /opt/stack/requirements /opt/stack/novaEntries in all requirements files will have their versions updated to match the entries listed in the global requirements. Excess entries will cause errors in hard mode (the default) or be ignored in soft mode.
generate-constraints
Compile a constraints file showing the versions resulting from
installing all of global-requirements.txt:
generate-constraints -p /usr/bin/python2.7 -p /usr/bin/python3 \
-b blacklist.txt -r global-requirements.txt > new-constraints.txtedit-constraints
Replace all references to a package in a constraints file with a new specification. Used by DevStack to enable git installations of libraries that are normally constrained:
edit-constraints oslo.db "-e file://opt/stack/oslo.db#egg=oslo.db"build-lower-constraints
Combine multiple lower-constraints.txt files to produce a list of the highest version of each package mentioned in the files. This can be used to produce the "highest minimum" for a global lower constraints list (a.k.a., the "TJ Maxx").
To use the script, run:
$ tox -e venv -- build-lower-constraints input1.txt input2.txtWhere the input files are lower-constraints.txt or requirements.txt files from one or more projects.
If the inputs are requirements files, a lower constraints list for the requirements is produced. If the inputs are lower-constraints.txt, the output includes the highest version of each package referenced in the files.
check-requirements
Run the validation checks from the requirements-check
job locally using the requirements-check tox
environment.
Run:
$ tox -e requirements-check -- /path/to/repo/to/testProposing changes
Look at the Review Guidelines and make sure your change meets them.
All changes to global-requirements.txt may dramatically
alter the contents of upper-constraints.txt due to adding
or removing transitive dependencies. As such you should always generate
a diff against the current merged constraints, otherwise your change may
fail if it is incompatible with the current tested constraints.
Regenerating involves five steps.
Install the dependencies needed to compile various Python packages:
sudo apt-get install $(bindep -b)Create a reference file (do this without your patch applied):
generate-constraints -p /usr/bin/python2.7 -p /usr/bin/python3 \ -b blacklist.txt -r global-requirements.txt > baselineApply your patch and generate a new reference file:
generate-constraints -p /usr/bin/python2.7 -p /usr/bin/python3 \ -b blacklist.txt -r global-requirements.txt > updatedDiff them:
diff -p baseline updatedApply the patch to
upper-constraints.txt. This may require some fiddling.edit-constraintcan do this for you when the change does not involve multiple lines for one package.
