Command line warnings-plugin

Command-line alternative for https://github.com/jenkinsci/warnings-plugin. Useable with plugin-less CI systems. It can be used with GitLab-CI to enable warning threshold setting for failing the job and for parsing warnings from various tools and report them as errors.

Installation

Every release is uploaded to pip so it can be installed simply by using pip.

# Python2
pip2 install mlx.warnings

# Python3
pip3 install mlx.warnings

You can find more details in Installation guide

Usage

Warnings plugin parses log messages as well as direct command stream. In case you want to create log file, you will need to redirect your stderr to some text file. You can do that with shell pipes or with command line arguments to command (if it supports outputting errors to file instead of stderr). Be aware that some commands print warnings on stdout.

Also warnings plugin log files need to be the last argument as otherwise the arguments after that are discarded, because they are considered as command arguments (with or without command flag).

Pipe example

Below is one of the ways to redirect your stderr to stdout and save it inside file.

yourcommand 2>&1 | tee doc_log.txt

Command example

Below is the command example for the plugin (keep in mind that parse commands are required).

mlx-warnings --command <yourcommand>

Running command

There are few ways to run warnings plugin. If you are playing with Python on your computer you want to use virtualenv. This will separate your packages per project and there is less chance of some dependency hell. You can initialize virtual environment in current directory by virtualenv . .

Melexis Warnings plugin can be called directly from shell/console using:

mlx-warnings -h

It has also possibility to be called as module from Python2 or Python3. In that case command will look like:

python -m mlx.warnings -h
python3 -m mlx.warnings -h

Help prints all currently supported commands and their usages.

The command returns (shell $? variable):

  • value 0 when the number of counted warnings is within the supplied minimum and maximum limits: ok,
  • number of counted warnings (positive) when the counter number is not within those limit.

Simple Command line options

Plugin has two forms of passing the arguments to checkers. The command line option which enables checkers and sets minimum and maximum to each checker individually, or the configuration file option which provides more flexibility and also traceability as it resides inside repository and provides option to adjust minimum and maximum per individual checker.

Parse for Sphinx warnings

After you saved your Sphinx warnings to the file, you can parse it with command:

# command line log file
mlx-warnings doc_log.txt --sphinx
# command line command execution
mlx-warnings --sphinx --command <commandforsphinx>

# explicitly as python module for log file
python3 -m mlx.warnings --sphinx doc_log.txt
python -m mlx.warnings --sphinx doc_log.txt
# explicitly as python module
python3 -m mlx.warnings --sphinx --command <commandforsphinx>
python -m mlx.warnings --sphinx --command <commandforsphinx>

Parse for Doxygen warnings

After you saved your Doxygen warnings to the file, you can parse it with command:

# command line log file
mlx-warnings doc_log.txt --doxygen
# command line command execution
mlx-warnings --doxygen --command <commandfordoxygen>

# explicitly as python module for log file
python3 -m mlx.warnings --doxygen doc_log.txt
python -m mlx.warnings --doxygen doc_log.txt
# explicitly as python module
python3 -m mlx.warnings --doxygen --command <commandfordoxygen>
python -m mlx.warnings --doxygen --command <commandfordoxygen>

Parse for JUnit failures

After you saved your JUnit XML output to the file, you can parse it with command:

# command line log file
mlx-warnings junit_output.xml --junit
# command line command execution
mlx-warnings --junit --command <commandforjunit>

# explicitly as python module for log file
python3 -m mlx.warnings --junit junit_output.xml
python -m mlx.warnings --junit junit_output.xml
# explicitly as python module
python3 -m mlx.warnings --junit --command <commandforjunit>
python -m mlx.warnings --junit --command <commandforjunit>

Parse for XMLRunner errors

When you run [XMLRunner](https://github.com/xmlrunner/unittest-xml-reporting) the errors are reported on the output, but they are not marked as failures in the test reports xml files. Since command exits as 1, we could not detect tests that just did not run (not failed). warnings-plugin now parses for the output with command:

# command line log file
mlx-warnings xmlrunner_log.txt --xmlrunner
# command line command execution
mlx-warnings --xmlrunner --command <commandforxmlrunner>

# explicitly as python module for log file
python3 -m mlx.warnings --xmlrunner xmlrunner_log.txt
python -m mlx.warnings --xmlrunner xmlrunner_log.txt
# explicitly as python module
python3 -m mlx.warnings --xmlrunner --command <commandforxmlrunner>
python -m mlx.warnings --xmlrunner --command <commandforxmlrunner>

Configuration file to pass options

Beside command line, you can pass options through the configuration file. Configuration file is in JSON format with a simple structure.

{
    "sphinx":{
        "enabled": true,
        "min": 0,
        "max": 0
    },
    "doxygen":{
        "enabled": false,
        "min": 0,
        "max": 0
    },
    "junit":{
        "enabled": false,
        "min": 0,
        "max": 0
    },
    "xmlrunner":{
        "enabled": false,
        "min": 0,
        "max": 0
    }
}

First key is checkername, then it contains a boolean value for key enabled, value for minimum number of warnings with key min and value for maximum number of warnings with key max. This structure allows simple expansion.

To run the plugin with configuration file you simply pass –config flag with path to configuration file

# command line log file
mlx-warnings --config pathtoconfig.json junit_output.xml
# command line command execution
mlx-warnings --config patchtoconfig.json --command <commandforjunit>

Other options

Since plugin is under active development there are new Features added fast. Important options currently include setting maximum number of warnings or minimum number of warnings, that are still acceptable to return 0 (success) return code. Look at scripts help, for more details about the options.

Issues and new Features

In case you have any problems with usage of the plugin, please open an issue on GitHub. Provide as many valid information as possible, as this will help us to resolve Issues faster. We would also like to hear your suggestions about new features which would help your Continuous Integration run better.

Contribute

There is a Contribution guide available if you would like to get involved in development of the plugin. We encourage anyone to contribute to our repository.
