# Contributor Covenant Code of Conduct

## Our Pledge

We as members, contributors, and leaders pledge to make participation in our

community a harassment-free experience for everyone, regardless of age, body

size, visible or invisible disability, ethnicity, sex characteristics, gender

identity and expression, level of experience, education, socio-economic status,

nationality, personal appearance, race, caste, color, religion, or sexual

identity and orientation.

We pledge to act and interact in ways that contribute to an open, welcoming,

diverse, inclusive, and healthy community.

## Our Standards

Examples of behavior that contributes to a positive environment for our

community include:

* Demonstrating empathy and kindness toward other people

* Being respectful of differing opinions, viewpoints, and experiences

* Giving and gracefully accepting constructive feedback

* Accepting responsibility and apologizing to those affected by our mistakes,

  and learning from the experience

* Focusing on what is best not just for us as individuals, but for the overall

  community

Examples of unacceptable behavior include:

* The use of sexualized language or imagery, and sexual attention or advances of

  any kind

* Trolling, insulting or derogatory comments, and personal or political attacks

* Public or private harassment

* Publishing others' private information, such as a physical or email address,

  without their explicit permission

* Other conduct which could reasonably be considered inappropriate in a

  professional setting

## Enforcement Responsibilities

SPDK core [maintainers](https://spdk.io/development/) are responsible for clarifying and enforcing our standards of

acceptable behavior and will take appropriate and fair corrective action in

response to any behavior that they deem inappropriate, threatening, offensive,

or harmful.

SPDK core maintainers have the right and responsibility to remove, edit, or reject

comments, commits, code, wiki edits, issues, and other contributions that are

not aligned to this Code of Conduct, and will communicate reasons for moderation

decisions when appropriate.

## Scope

This Code of Conduct applies within all community spaces, and also applies when

an individual is officially representing the community in public spaces.

Examples of representing our community include using an official e-mail address,

posting via an official social media account, or acting as an appointed

representative at an online or offline event.

## Enforcement

Instances of abusive, harassing, or otherwise unacceptable behavior may be

reported privately to any of the SPDK core maintainers. All complaints will be

reviewed and investigated promptly and fairly.

All SPDK core maintainers are obligated to respect the privacy and security of the

reporter of any incident.

## Enforcement Guidelines

SPDK core maintainers will follow these Community Impact Guidelines in determining

the consequences for any action they deem in violation of this Code of Conduct:

### 1. Correction

**Community Impact**: Use of inappropriate language or other behavior deemed

unprofessional or unwelcome in the community.

**Consequence**: A private, written warning from SPDK core maintainers, providing

clarity around the nature of the violation and an explanation of why the

behavior was inappropriate. A public apology may be requested.

### 2. Warning

**Community Impact**: A violation through a single incident or series of

actions.

**Consequence**: A warning with consequences for continued behavior. No

interaction with the people involved, including unsolicited interaction with

those enforcing the Code of Conduct, for a specified period of time. This

includes avoiding interactions in community spaces as well as external channels

like social media. Violating these terms may lead to a temporary or permanent

ban.

### 3. Temporary Ban

**Community Impact**: A serious violation of community standards, including

sustained inappropriate behavior.

**Consequence**: A temporary ban from any sort of interaction or public

communication with the community for a specified period of time. No public or

private interaction with the people involved, including unsolicited interaction

with those enforcing the Code of Conduct, is allowed during this period.

Violating these terms may lead to a permanent ban.

### 4. Permanent Ban

**Community Impact**: Demonstrating a pattern of violation of community

standards, including sustained inappropriate behavior, harassment of an

individual, or aggression toward or disparagement of classes of individuals.

**Consequence**: A permanent ban from any sort of public interaction within the

community.
