Build analysis library and tools to handle and process build logs.

Project description

Thoth: Build Analysers

This is a set of analysers that will retrieve information from build logs.


Lead by Example:

Consider a log produced by the pip package installer:

We can also use pipenv, see the How it works section

Cannot uninstall 'certifi'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
You are using pip version 18.1, however version 19.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
  

In the log file, there is a line 76 which contains the information about the package which broke the installation: certifi. We want to extract this information. In the most common case, we want to get a report containing the observations about this particular build log.

from thoth.build_analysers.analysis import build_breaker_report

log: str = ...
report: dict = build_breaker_report(log)

The result is a dictionary which can further be formatted by the convenient build_breaker_format_report function.

from thoth.build_analysers.analysis import build_breaker_format_report

print(build_breaker_format_report(report))

And you should see something like this:

Build breaker:

    {
        "already_satisfied": null,
        "source": "thoth-lab",
        "target": "certifi",
        "version_installed": null,
        "version_specified": ">=2017.4.17"
    }

Probable reason:

    76: Cannot uninstall 'certifi'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

Candidates:

    [
        "76: Cannot uninstall 'certifi'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall."
    ]


How it works

The logic is quite simple (and also a bit naive). Really, no rocket science, just a lot of string matching.

The intuition

The approach currently handles logs produced by pip and pipenv package installers. For both of them, there is a set of patterns which, if found in a log, potentially indicate an error. These patterns are strings formatted according to the PEP3101 string formatting syntax and are stored in the resources folder as pandas DataFrames.

We evaluate the 'goodness' of a match for each line of the log file with respect to the relevant set of patterns and label them based on the given thresholds. Currently, the ERROR threshold is set to the score of >=0.6 on the scale from 0 through 1.0. Finally, we try to search for package names in the log file to construct a dependency table. We filter the ERRORs containing a package name and we've got ourselves a list of build breakers.


Installation

The package is available on PyPI:

pip install thoth-build-analysers

And you're good to go :thumbsup:
