Wardoff

Wardoff (pronounced ward off) aim to help you to maintain your code base clean and up-to-date by reducing the pain of collect informations about all your underlaying libraries in your stack in a proactively manner.

Wardoff looking for deprecated stuffs in project requirements and underlying libraries to help you to keep your code up-to-date.

The main goal of wardoff is to analyze all requirements of a given project to extract deprecated things from their codes.

For each analyze a dedicated python virtual environment is built and project's requirements are installed within. Then installed source code files of project's requirement are analyzed one by one.

Code analyze of the requirements is based on AST and python tokens. Each source code file of each underlaying library is analyzed in this way.

You can pass a list of constraints to apply to your analyze to be sure to match the right versions of your underlaying libraries.

Traditionally projects maintainers are informed that functions will become deprecated or removed by reading documentation or by observing deprecation warning at the runtime in logs. When your stack grow and the number of requirements in your stack increase it could be painful to stay up-to-date, wardoff aim to collect for you all these infos by using only 1 command without needing any runtime environment setup.

Install

Still in development and really unstable, however you can install unstable development versions by using:

$ python3 -m pip install --user wardoff

Requirements

• python3.8+
• git

Usages

From a named package

Found deprecated things from a named package (directly from pypi):

$ wardoff niet # will list all deprecations founds in niet is requirements
$ wardoff oslo.messaging # will list all deprecations founds in oslo.messaging is requirements
$ wardoff oslo.messaging==12.2.2 # will list all deprecations founds in oslo.messaging 12.2.2 is requirements
$ wardoff oslo.messaging==1.3.0 # will list all deprecations founds in oslo.messaging 1.3.0 is requirements

From the current directory

(Coming soon - not yet implemented) Retrieve deprecated things from the current working directory. Retrieve requirements from:

• requirements.txt
• test-requirements.txt
• *-requirements.txt

Example:

$ wardoff # will list all deprecations founds in requirements founds in current directory

From a distant repository

(Coming soon - not yet implemented) Retrieve deprecated things from a distgit repo.

Example:

$ wardoff https://opendev.org/openstack/nova/ # from opendev.org
$ wardoff https://github.com/openstack/nova # from github.com
$ wardoff git@github.com:openstack/nova # by using git format

From a local repository

(Coming soon - not yet implemented) Retrieve deprecated things from a distgit repo.

Example:

$ wardoff ~/dev/nova # from a local clone of openstack/nova

Side features

tokenizer

Wardoff provide a CLI tokenizer which can be used against code passed through the CLI or by passing a file path and a specific line to read.

Example with raw code passed through the CLI:

$ wardoff-tokenizer "def person(name, age):"
TokenInfo(type=62 (ENCODING), string='utf-8', start=(0, 0), end=(0, 0), line='')
TokenInfo(type=1 (NAME), string='def', start=(1, 0), end=(1, 3), line='def person(name, age):')
TokenInfo(type=1 (NAME), string='person', start=(1, 4), end=(1, 10), line='def person(name, age):')
TokenInfo(type=54 (OP), string='(', start=(1, 10), end=(1, 11), line='def person(name, age):')
TokenInfo(type=1 (NAME), string='name', start=(1, 11), end=(1, 15), line='def person(name, age):')
TokenInfo(type=54 (OP), string=',', start=(1, 15), end=(1, 16), line='def person(name, age):')
TokenInfo(type=1 (NAME), string='age', start=(1, 17), end=(1, 20), line='def person(name, age):')
TokenInfo(type=54 (OP), string=')', start=(1, 20), end=(1, 21), line='def person(name, age):')
TokenInfo(type=54 (OP), string=':', start=(1, 21), end=(1, 22), line='def person(name, age):')
TokenInfo(type=4 (NEWLINE), string='', start=(1, 22), end=(1, 23), line='')
TokenInfo(type=0 (ENDMARKER), string='', start=(2, 0), end=(2, 0), line='')

Another example by passing a file line to tokenize:

wardoff-tokenizer ~/dev/wardoff/wardoff/tokenizer.py+12

It will tokenize the line number 12 of the file ~/dev/wardoff/wardoff/tokenizer.py

For further options with this command:

$ wardoff-tokenizer -h

freeze

Wardoff allow you to freeze installed requirements. It will provide a similar output than pip freeze but it will only print requirements related the given package.

Example:

$ wardoff-freeze oslo.messaging==1.3.0
amqp==2.6.0
Babel==2.8.0
certifi==2020.6.20
chardet==3.0.4
debtcollector==2.2.0
dnspython==2.0.0
eventlet==0.25.2
greenlet==0.4.16
idna==2.10
iso8601==0.1.12
kombu==4.6.11
monotonic==1.5
netaddr==0.8.0
oslo.config==8.3.1
oslo.i18n==5.0.0
pbr==5.4.5
pytz==2020.1
PyYAML==5.3.1
requests==2.24.0
rfc3986==1.4.0
six==1.15.0
stevedore==3.2.0
urllib3==1.25.10
vine==1.3.0
wrapt==1.12.1

The future of wardoff

We plan to introduce more features like issues and pull requests or patches harvesting.
