Contribute

Our aim is to build a lively community, hence, we welcome any exchange and collaboration with individuals and organizations interested in the use, support and extension of Eclipse Steady.

To contribute, read on to learn about your options:

Help Others

You can help by helping others who use Eclipse Steady and need support. Find them on Stack Overflow.

Report Bugs

If you find a bug - a behavior of the code contradicting its specification - you are welcome to report it. We can only handle well-reported, actual bugs, so please follow the guidelines below and use forums like Stack Overflow for support questions or when in doubt whether the issue is an actual bug.

Once you have familiarized with the guidelines, you can go to the GitHub issue tracker to report the issue.

Quick Checklist for Bug Reports

Issue report checklist:

  • Real, current bug
  • No duplicate
  • Reproducible
  • Good summary
  • Well-documented
  • Minimal example
  • Use the template

Requirements for a bug report

These eight requirements are the mandatory base of a good bug report:

  1. Only real bugs: please do your best to make sure to only report real bugs! Do not report:
    • issues caused by application code or any code outside Eclipse Steady.
    • something that behaves just different from what you expected. A bug is when something behaves different than specified. When in doubt, ask in a forum.
    • something you do not get to work properly. Use a support forum like Stack Overflow to request help.
    • feature requests. Well, this is arguable: critical or easy-to-do enhancement suggestions are welcome, but we do not want to use the issue tracker as wishlist.
  2. No duplicate: you have searched the issue tracker to make sure the bug has not yet been reported
  3. Good summary: the summary should be specific to the issue
  4. Current bug: the bug can be reproduced in the most current version (state the tested version!)
  5. Reproducible bug: there are clear steps to reproduce given. This includes, where possible:
    • a URL to access the example
    • any required user/password information (do not reveal any credentials that could be mis-used!)
    • detailed and complete step-by-step instructions to reproduce the bug
  6. Precise description:
    • precisely state the expected and the actual behavior
    • give information about the used browser/device and its version, if possible also the behavior in other browsers/devices
    • if the bug is about wrong UI appearance, attach a screenshot and mark what is wrong
    • generally give as much additional information as possible. (But find the right balance: do not invest hours for a very obvious and easy to solve issue. When in doubt, give more information.)
  7. Minimal example: it is highly encouraged to provide a minimal example to reproduce in e.g. jsbin: isolate the application code which triggers the issue and strip it down as much as possible as long as the issue still occurs. If several files are required, you can create a gist. This may not always be possible and sometimes be overkill, but it always helps analyzing a bug.
  8. Only one bug per report: open different tickets for different issues

You are encouraged to use this template.

Please report bugs in English, so all users can understand them.

If the bug appears to be a regression introduced in a new version of Eclipse Steady, try to find the closest versions between which it was introduced.

Issue handling process

When an issue is reported, a committer will look at it and either confirm it as a real issue (by giving the "approved" label), close it if it is not an issue, or ask for more details. Approved issues are then either assigned to a committer in GitHub, reported in our internal issue handling system, or left open as "contribution welcome" for easy or not urgent fixes.

An issue that is about a real bug is closed as soon as the fix is committed. The closing comment explains which patch version(s) will contain the fix.

Usage of Labels

Github offers labels to categorize issues. We defined the following labels so far:

Labels for issue categories:

  • bug: this issue is a bug in the code
  • documentation: this issue is about wrong documentation
  • enhancement: this is not a bug report, but an enhancement request

Status of open issues:

  • unconfirmed: this report needs confirmation whether it is really a bug (no label; this is the default status)
  • approved: this issue is confirmed to be a bug
  • author action: the author is required to provide information
  • contribution welcome: this fix/enhancement is approved and you are invited to contribute it

Status/resolution of closed issues:

  • fixed: a fix for the issue was provided
  • duplicate: the issue is also reported in a different ticket and is handled there
  • invalid: for some reason or another this issue report will not be handled further (maybe lack of information or issue does not apply anymore)
  • works: not reproducible or working as expected
  • wontfix: while acknowledged to be an issue, a fix cannot or will not be provided

The labels can only be set and modified by committers.

Issue Reporting Disclaimer

We want to improve the quality of Eclipse Steady and good bug reports are welcome! But our capacity is limited, so we cannot handle questions or consultation requests and we cannot afford to ask for required details. So we reserve the right to close or to not process insufficient bug reports in favor of those which are very cleanly documented and easy to reproduce. Even though we would like to solve each well-documented issue, there is always the chance that it won't happen - remember: Eclipse Steady is Open Source and comes without warranty.

Analyze Bugs

Analyzing issue reports can be a lot of effort. Any help is welcome! Go to the Github issue tracker and find an open issue which needs additional work or a bugfix.

Additional work may be further information, or a minimized jsbin example or gist, or it might be a hint that helps understanding the issue. Maybe you can even find and contribute a bugfix?

Contribute Code

You are welcome to contribute code in order to fix bugs or to implement new features.

There are three important things to know:

  1. You must be aware of the Apache License (which describes contributions) and agree to the Eclipse Contributor Agreement (see below).
  2. There are several requirements regarding code style, quality, and product standards which need to be met (we also have to follow them). The respective section below gives more details on the coding guidelines.
  3. Not all proposed contributions can be accepted. Some features may e.g. just fit a third-party add-on better. The code must fit the overall direction of the open-source vulnerability assessment tool and really improve it, so there should be some "bang for the byte". For most bug fixes this is a given, but major feature implementation first need to be discussed with one of the Eclipse Steady committers , possibly one who touched the related code recently. The more effort you invest, the better you should clarify in advance whether the contribution fits: the best way would be to just open an enhancement ticket in the issue tracker to discuss the feature you plan to implement (make it clear you intend to contribute). We will then forward the proposal to the respective code owner, this avoids disappointment.

Eclipse Contributor Agreement (ECA)

Due to legal reasons, contributors will be asked to accept the ECA before they submit the first pull request to this projects, this happens in an automated fashion during the submission process. Please see the Eclipse Contributor Agreement for more information.

Contribution Content Guidelines

Contributed content can be accepted if it:

  1. is useful to improve Eclipse Steady (explained above)
  2. follows the applicable guidelines and standards

The second requirement could be described in entire books and would still lack a 100%-clear definition, so you will get a committer's feedback if something is not right.

These are some of the most important rules to give you an initial impression:

  • Check your Java code with Spotbugs by running mvn -Dspotbugs.excludeFilterFile=findbugs-exclude.xml -Dspotbugs.includeFilterFile=findbugs-include.xml -Dspotbugs.failOnError=true clean compile com.github.spotbugs:spotbugs-maven-plugin:4.0.4:check. Code with MEDIUM or HIGH priority findings in one of the following categories will be rejected (see findbugs-include.xml): PERFORMANCE, SECURITY, CORRECTNESS, MALICIOUS_CODE, MT_CORRECTNESS
  • Strictly follow Google's Java Style Guide, e.g., by installing the respective plugin for your IDE or by using the script .travis/check_code_style.sh. Contributions will be automatically checked using google-java-format, and rejected if they do not comply.
  • Use variable naming conventions like in the other files you are seeing (e.g. hungarian notation)
  • No System.out.println
  • Only access public APIs of other entities (there are exceptions, but this is the rule)
  • Comment your code where it gets non-trivial
  • Keep an eye on performance and memory consumption
  • Write a unit test
  • Do not do any incompatible changes, especially do not modify the name or behavior of public API methods or properties
  • Always consider the developer who USES your control/code!
    • Think about what code and how much code he/she will need to write to use your feature
    • Think about what she/he expects your control/feature to do

If this list sounds lengthy and hard to achieve - well, that's what WE have to comply with as well, and it's by far not complete…

How to contribute - the Process

  1. Make sure the change would be welcome (e.g. a bugfix or a useful feature); best do so by proposing it in a GitHub issue
  2. Create a branch forking Eclipse Steady repository and do your change
  3. Commit and push your changes on that branch

    • When you have several commits, squash them into one (see this explanation) - this also needs to be done when additional changes are required after the code review
  4. Provide a meaningful commit message incl. links to the respective issue

  5. If your change fixes an issue reported at GitHub, add the following line to the commit message:
    • Fixes https://github.com/eclipse/steady/issues/(issueNumber)
    • Do NOT add a colon after "Fixes" - this prevents automatic closing.
    • When your pull request number is known (e.g. because you enhance a pull request after a code review), you can also add the line Closes https://github.com/eclipse/steady/pull/(pullRequestNumber)
  6. Create a Pull Request to https://github.com/eclipse/steady
  7. If necessary, sign the Eclipse Contributor Agreement
  8. Wait for our code review and approval, possibly enhancing your change on request

    • Note that Eclipse Steady developers also have their regular duties, so depending on the required effort for reviewing, testing and clarification this may take a while
  9. Once the change has been approved we will inform you in a comment

  10. Your pull request cannot be merged directly into the branch (internal SAP processes), but will be merged internally and immediately appear in the public repository as well. Pull requests for non-code branches (like "gh-pages" for the website) can be directly merged.
  11. We will close the pull request, feel free to delete the now obsolete branch

Contribute to the Vulnerability Knowledge Base

Every installation of Eclipse Steady relies on a database with detailed information about vulnerable code (methods, functions, etc.) in open-source software components. This database is populated by analyzing the source code changes (commits) done by open source developers to fix a given vulnerability.

This analysis is done using the patch-analyzer, which takes several arguments as input, e.g., the source code repository of the respective component, the commit identifier(s), and a vulnerability identifier. Analysis results such as the names and abstract syntax trees of modified methods are eventually stored in the local PostgreSQL database of Eclipse Steady.

In order to prevent that each and every user of Eclipse Steady has to collect the repository URL and the fix commit(s) for a given vulnerability by himself, we created the shared vulnerability assessment knowledge base The maintenance of this knowledge base will become - in the ideal case - a community effort involving both open source projects as well as users of Eclipse Steady.

Please create an issue if you want to provide new information about publicly disclosed vulnerabilities in open source components, or correct an existing entry.
