# Contributor Covenant Code of Conduct
|
||||
|
||||
*Note*: this Code of Conduct pertains to individuals' behavior. Please also see the [Organizational Code of Conduct][OCoC].
|
||||
|
||||
## Our Pledge
|
||||
|
||||
In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
|
||||
|
||||
## Our Standards
|
||||
|
||||
Examples of behavior that contributes to creating a positive environment include:
|
||||
|
||||
* Using welcoming and inclusive language
|
||||
* Being respectful of differing viewpoints and experiences
|
||||
* Gracefully accepting constructive criticism
|
||||
* Focusing on what is best for the community
|
||||
* Showing empathy towards other community members
|
||||
|
||||
Examples of unacceptable behavior by participants include:
|
||||
|
||||
* The use of sexualized language or imagery and unwelcome sexual attention or advances
|
||||
* Trolling, insulting/derogatory comments, and personal or political attacks
|
||||
* Public or private harassment
|
||||
* Publishing others' private information, such as a physical or electronic address, without explicit permission
|
||||
* Other conduct which could reasonably be considered inappropriate in a professional setting
|
||||
|
||||
## Our Responsibilities
|
||||
|
||||
Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
|
||||
|
||||
Project 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, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
|
||||
|
||||
## Scope
|
||||
|
||||
This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
|
||||
|
||||
## Enforcement
|
||||
|
||||
Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the Bytecode Alliance CoC team at [report@bytecodealliance.org](mailto:report@bytecodealliance.org). The CoC team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The CoC team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
|
||||
|
||||
Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the Bytecode Alliance's leadership.
|
||||
|
||||
## Attribution
|
||||
|
||||
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, available at [http://contributor-covenant.org/version/1/4][version]

|
||||
direction or management of such entity, whether by contract or
|
||||
otherwise, or (ii) ownership of fifty percent (50%) or more of the
|
||||
outstanding shares, or (iii) beneficial ownership of such entity.
|
||||
|
||||
"You" (or "Your") shall mean an individual or Legal Entity
|
||||
exercising permissions granted by this License.
|
||||

|
||||

|
||||
|
||||
"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|
||||
not limited to compiled object code, generated documentation,
|
||||
and conversions to other media types.
|
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or
|
||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|
||||
Licensor for the purpose of discussing and improving the Work, but
|
||||
excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,

the copyright owner that is granting the License.
|
||||
|

other entities that control, are controlled by, or are under common
|
||||
control with that entity. For the purposes of this definition,

direction or management of such entity, whether by contract or
|
||||
otherwise, or (ii) ownership of fifty percent (50%) or more of the

|
||||
source, and configuration files.
|
||||
|
||||
"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|
||||
not limited to compiled object code, generated documentation,
|
||||
and conversions to other media types.
|
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or
|
||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|
||||
Licensor for the purpose of discussing and improving the Work, but
|
||||
excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.

||||

||||

# Bytecode Alliance Organizational Code of Conduct (OCoC)
|
||||
|
||||
*Note*: this Code of Conduct pertains to organizations' behavior. Please also see the [Individual Code of Conduct](CODE_OF_CONDUCT.md).
|
||||
|
||||
## Preamble
|
||||
|
||||
The Bytecode Alliance (BA) welcomes involvement from organizations,
|
||||
including commercial organizations. This document is an
|
||||
*organizational* code of conduct, intended particularly to provide
|
||||
guidance to commercial organizations. It is distinct from the
|
||||
[Individual Code of Conduct (ICoC)](CODE_OF_CONDUCT.md), and does not
|
||||
replace the ICoC. This OCoC applies to any group of people acting in
|
||||
concert as a BA member or as a participant in BA activities, whether
|
||||
or not that group is formally incorporated in some jurisdiction.
|
||||
|
||||
The code of conduct described below is not a set of rigid rules, and
|
||||
we did not write it to encompass every conceivable scenario that might
|
||||
arise. For example, it is theoretically possible there would be times
|
||||
when asserting patents is in the best interest of the BA community as
|
||||
a whole. In such instances, consult with the BA, strive for
|
||||
consensus, and interpret these rules with an intent that is generous
|
||||
to the community the BA serves.
|
||||
|
||||
While we may revise these guidelines from time to time based on
|
||||
real-world experience, overall they are based on a simple principle:
|
||||
|
||||
*Bytecode Alliance members should observe the distinction between
|
||||
public community functions and private functions — especially
|
||||
commercial ones — and should ensure that the latter support, or at
|
||||
least do not harm, the former.*
|
||||
|
||||
## Guidelines
|
||||
|
||||
* **Do not cause confusion about Wasm standards or interoperability.**
|
||||
|
||||
Having an interoperable WebAssembly core is a high priority for
|
||||
the BA, and members should strive to preserve that core. It is fine
|
||||
to develop additional non-standard features or APIs, but they
|
||||
should always be clearly distinguished from the core interoperable
|
||||
Wasm.
|
||||
|
||||
Treat the WebAssembly name and any BA-associated names with
|
||||
respect, and follow BA trademark and branding guidelines. If you
|
||||
distribute a customized version of software originally produced by
|
||||
the BA, or if you build a product or service using BA-derived
|
||||
software, use names that clearly distinguish your work from the
|
||||
original. (You should still provide proper attribution to the
|
||||
original, of course, wherever such attribution would normally be
|
||||
given.)
|
||||
|
||||
Further, do not use the WebAssembly name or BA-associated names in
|
||||
other public namespaces in ways that could cause confusion, e.g.,
|
||||
in company names, names of commercial service offerings, domain
|
||||
names, publicly-visible social media accounts or online service
|
||||
accounts, etc. It may sometimes be reasonable, however, to
|
||||
register such a name in a new namespace and then immediately donate
|
||||
control of that account to the BA, because that would help the project
|
||||
maintain its identity.
|
||||
|
||||
For further guidance, see the BA Trademark and Branding Policy
|
||||
[TODO: create policy, then insert link].
|
||||
|
||||
* **Do not restrict contributors.** If your company requires
|
||||
employees or contractors to sign non-compete agreements, those
|
||||
agreements must not prevent people from participating in the BA or
|
||||
contributing to related projects.
|
||||
|
||||
This does not mean that all non-compete agreements are incompatible
|
||||
with this code of conduct. For example, a company may restrict an
|
||||
employee's ability to solicit the company's customers. However, an
|
||||
agreement must not block any form of technical or social
|
||||
participation in BA activities, including but not limited to the
|
||||
implementation of particular features.
|
||||
|
||||
The accumulation of experience and expertise in individual persons,
|
||||
who are ultimately free to direct their energy and attention as
|
||||
they decide, is one of the most important drivers of progress in
|
||||
open source projects. A company that limits this freedom may hinder
|
||||
the success of the BA's efforts.
|
||||
|
||||
* **Do not use patents as offensive weapons.** If any BA participant
|
||||
prevents the adoption or development of BA technologies by
|
||||
asserting its patents, that undermines the purpose of the
|
||||
coalition. The collaboration fostered by the BA cannot include
|
||||
members who act to undermine its work.
|
||||
|
||||
* **Practice responsible disclosure** for security vulnerabilities.
|
||||
Use designated, non-public reporting channels to disclose technical
|
||||
vulnerabilities, and give the project a reasonable period to
|
||||
respond, remediate, and patch. [TODO: optionally include the
|
||||
security vulnerability reporting URL here.]
|
||||
|
||||
Vulnerability reporters may patch their company's own offerings, as
|
||||
long as that patching does not significantly delay the reporting of
|
||||
the vulnerability. Vulnerability information should never be used
|
||||
for unilateral commercial advantage. Vendors may legitimately
|
||||
compete on the speed and reliability with which they deploy
|
||||
security fixes, but withholding vulnerability information damages
|
||||
everyone in the long run by risking harm to the BA project's
|
||||
reputation and to the security of all users.
|
||||
|
||||
* **Respect the letter and spirit of open source practice.** While
|
||||
there is not space to list here all possible aspects of standard
|
||||
open source practice, some examples will help show what we mean:
|
||||
|
||||
* Abide by all applicable open source license terms. Do not engage
|
||||
in copyright violation or misattribution of any kind.
|
||||
|
||||
* Do not claim others' ideas or designs as your own.
|
||||
|
||||
* When others engage in publicly visible work (e.g., an upcoming
|
||||
demo that is coordinated in a public issue tracker), do not
|
||||
unilaterally announce early releases or early demonstrations of
|
||||
that work ahead of their schedule in order to secure private
|
||||
advantage (such as marketplace advantage) for yourself.
|
||||
|
||||
The BA reserves the right to determine what constitutes good open
|
||||
source practices and to take action as it deems appropriate to
|
||||
encourage, and if necessary enforce, such practices.
|
||||
|
||||
## Enforcement
|
||||
|
||||
Instances of organizational behavior in violation of the OCoC may
|
||||
be reported by contacting the Bytecode Alliance CoC team at
|
||||
[report@bytecodealliance.org](mailto:report@bytecodealliance.org). The
|
||||
CoC team will review and investigate all complaints, and will respond
|
||||
in a way that it deems appropriate to the circumstances. The CoC team
|
||||
is obligated to maintain confidentiality with regard to the reporter of
|
||||
an incident. Further details of specific enforcement policies may be
|
||||
posted separately.
|
||||
|
||||
When the BA deems an organization in violation of this OCoC, the BA
|
||||
will, at its sole discretion, determine what action to take. The BA
|
||||
will decide what type, degree, and duration of corrective action is
|
||||
needed, if any, before a violating organization can be considered for
|
||||
membership (if it was not already a member) or can have its membership
|
||||
reinstated (if it was a member and the BA canceled its membership due
|
||||
to the violation).
|
||||
|
||||
In practice, the BA's first approach will be to start a conversation,
|
||||
with punitive enforcement used only as a last resort. Violations
|
||||
often turn out to be unintentional and swiftly correctable with all
|
||||
parties acting in good faith.

This library introduces `OwnedFd`, `BorrowedFd`, and supporting types and
|
||||
traits, and corresponding features for Windows, which implement safe owning
|
||||
and borrowing I/O lifetime patterns.
|
||||
|
||||
This is associated with [RFC 3128], the I/O Safety RFC, which is now merged.
|
||||
Work is now underway to move the `OwnedFd` and `BorrowedFd` types and `AsFd`
|
||||
trait developed here into `std`.
|
||||
|
||||
For a quick taste, check out the code examples:
|
||||
|
||||
- [hello], a basic demo of this API, doing low-level I/O manually, using the
|
||||
[provided example FFI bindings]
|
||||
- [easy-conversions], demonstrating the `from_into` convenience feature for
|
||||
converting from an `impl Into*` into an `impl From*`.
|
||||
- [portable-views], demonstrating the convenience feature which allows one
|
||||
to temporarily "view" a file descriptor as any owning type such as `File`
|
||||
- [flexible-apis], demonstrating how to write library APIs that accept
|
||||
untyped I/O resources.
|
||||
- [owning-wrapper], demonstrating how to implement a type which wraps an
|
||||
`Owned*` type.

||||

||||

||||

|
||||
[provided example FFI bindings]: https://github.com/sunfishcode/io-lifetimes/blob/main/src/example_ffi.rs
|
||||
|
||||
The core of the API is very simple, and consists of two main types and three
|
||||
main traits:
|
||||
|
||||
```rust
|
||||
pub struct BorrowedFd<'fd> { ... }
|
||||
pub struct OwnedFd { ... }
|
||||
|
||||
pub trait AsFd { ... }
|
||||
pub trait IntoFd { ... }
|
||||
pub trait FromFd { ... }
|
||||
|
||||
impl AsRawFd for BorrowedFd<'_> { ... }
|
||||
impl AsRawFd for OwnedFd { ... }
|
||||
impl IntoRawFd for OwnedFd { ... }
|
||||
impl FromRawFd for OwnedFd { ... }
|
||||
|
||||
impl Drop for OwnedFd { ... }
|
||||
|
||||
impl AsFd for BorrowedFd<'_> { ... }
|
||||
impl AsFd for OwnedFd { ... }
|
||||
impl IntoFd for OwnedFd { ... }
|
||||
impl FromFd for OwnedFd { ... }
|
||||
```
|
||||
|
||||
On Windows, there are `Handle` and `Socket` versions of every `Fd` thing, and
|
||||
a special `HandleOrInvalid` type to cope with inconsistent error reporting
|
||||
in the Windows API.
|
||||
|
||||
## The magic of transparency
|
||||
|
||||
Here's the fun part. `BorrowedFd` and `OwnedFd` are `repr(transparent)` and
|
||||
hold `RawFd` values, and `Option<BorrowedFd>` and `Option<OwnedFd>` are
|
||||
FFI-safe (on Rust >= 1.63), so they can all be used in FFI [directly]:
|
||||
|
||||
[directly]: https://github.com/sunfishcode/io-lifetimes/blob/main/src/example_ffi.rs
|
||||
|
||||
```rust
|
||||
extern "C" {
|
||||
pub fn open(pathname: *const c_char, flags: c_int, ...) -> Option<OwnedFd>;
|
||||
pub fn read(fd: BorrowedFd<'_>, ptr: *mut c_void, size: size_t) -> ssize_t;
|
||||
pub fn write(fd: BorrowedFd<'_>, ptr: *const c_void, size: size_t) -> ssize_t;
|
||||
pub fn close(fd: OwnedFd) -> c_int;
|
||||
}
|
||||
```
|
||||
|
||||
With bindings like this, users never have to touch `RawFd` values. Of course,
|
||||
not all code will do this, but it is a fun feature for code that can. This
|
||||
is what motivates having `BorrowedFd` instead of just using `&OwnedFd`.
|
||||
|
||||
Note the use of `Option<OwnedFd>` as the return value of `open`, representing
|
||||
the fact that it can either succeed or fail.
|
||||
|
||||
## I/O Safety in Rust
|
||||
|
||||
I/O Safety feature is stablized in Rust 1.63. With this version or later,
|
||||
io-lifetimes will use and re-export the standard-library types and traits. With
|
||||
older versions, io-lifetimes defines its own copy of these types and traits.
|
||||
|
||||
io-lifetimes also includes several features which are not (yet?) in std,
|
||||
including the portability traits `AsFilelike`/`AsSocketlike`/etc., the
|
||||
`from_into_*` functions in the `From*` traits, and [views].
|
||||
|
||||
[views]: https://docs.rs/io-lifetimes/*/io_lifetimes/views/index.html
|
||||
|
||||
## Prior Art
|
||||
|
||||
There are several similar crates: [fd](https://crates.io/crates/fd),
|
||||
[filedesc](https://crates.io/crates/filedesc),
|
||||
[filedescriptor](https://crates.io/crates/filedescriptor),
|
||||
[owned-fd](https://crates.io/crates/owned-fd), and
|
||||
[unsafe-io](https://crates.io/crates/unsafe-io).
|
||||
|
||||
Some of these provide additional features such as the ability to create pipes
|
||||
or sockets, to get and set flags, and to do read and write operations.
|
||||
io-lifetimes omits these features, leaving them to to be provided as separate
|
||||
layers on top.
|
||||
|
||||
Most of these crates provide ways to duplicate a file descriptor. io-lifetimes
|
||||
currently treats this as another feature that can be provided by a layer on
|
||||
top, though if there are use cases where this is a common operation, it could
|
||||
be added.
|
||||
|
||||
io-lifetimes's distinguishing features are its use of `repr(transparent)`
|
||||
to support direct FFI usage, niche optimizations so `Option` can support direct
|
||||
FFI usafe as well (on Rust >= 1.63), lifetime-aware `As*`/`Into*`/`From*`
|
||||
traits which leverage Rust's lifetime system and allow safe and checked
|
||||
`from_*` and `as_*`/`into_*` functions, and powerful convenience features
|
||||
enabled by its underlying safety.
|
||||
|
||||
io-lifetimes also has full Windows support, as well as Unix/Windows
|
||||
portability abstractions, covering both file-like and socket-like types.
|
||||
|
||||
io-lifetimes's [`OwnedFd`] type is similar to
|
||||
[fd](https://crates.io/crates/fd)'s
|
||||
[`FileDesc`](https://docs.rs/fd/0.2.3/fd/struct.FileDesc.html). io-lifetimes
|
||||
doesn't have a `close_on_drop` parameter, and instead uses [`OwnedFd`] and
|
||||
[`BorrowedFd`] to represent dropping and non-dropping handles, respectively, in
|
||||
a way that is checked at compile time rather than runtime.
|
||||
|
||||
io-lifetimes's [`OwnedFd`] type is also similar to
|
||||
[filedesc](https://crates.io/crates/filedesc)'s
|
||||
[`FileDesc`](https://docs.rs/filedesc/0.3.0/filedesc/struct.FileDesc.html)
|
||||
io-lifetimes's `OwnedFd` reserves the value -1, so it doesn't need to test for
|
||||
`-1` in its `Drop`, and `Option<OwnedFd>` (on Rust >= 1.63) is the same size
|
||||
as `FileDesc`.
|
||||
|
||||
io-lifetimes's [`OwnedFd`] type is also similar to
|
||||
[owned-fd](https://crates.io/crates/owned-fd)'s
|
||||
[`OwnedFd`](https://docs.rs/owned-fd/0.1.0/owned_fd/struct.OwnedFd.html).
|
||||
io-lifetimes doesn't implement `Clone`, because duplicating a file descriptor
|
||||
can fail due to OS process limits, while `Clone` is an infallible interface.
|
||||
|
||||
io-lifetimes's [`BorrowedFd`] is similar to
|
||||
[owned-fd](https://crates.io/crates/owned-fd)'s
|
||||
[`FdRef`](https://docs.rs/owned-fd/0.1.0/owned_fd/struct.FdRef.html), except it
|
||||
uses a lifetime parameter and `PhantomData` rather than transmuting a raw file
|
||||
descriptor value into a reference value.
|
||||
|
||||
io-lifetimes's convenience features are similar to those of
|
||||
[unsafe-io](https://crates.io/crates/unsafe-io), but io-lifetimes is built on
|
||||
its own `As*`/`Into*`/`From*` traits, rather than extending
|
||||
`AsRaw*`/`IntoRaw*`/`FromRaw*` with
|
||||
[`OwnsRaw`](https://docs.rs/unsafe-io/0.6.9/unsafe_io/trait.OwnsRaw.html), so
|
||||
they're simpler and safer to use. io-lifetimes doesn't include unsafe-io's
|
||||
`*ReadWrite*` or `*HandleOrSocket*` abstractions, and leaves these as features
|
||||
to be provided by separate layers on top.
|
||||
|
||||
## Minimum Supported Rust Version (MSRV)
|
||||
|
||||
This crate currently works on the version of [Rust on Debian stable], which is
|
||||
currently Rust 1.48. This policy may change in the future, in minor version
|
||||
releases, so users using a fixed version of Rust should pin to a specific
|
||||
version of this crate.

||||

||||

//! Experimental new types and traits to replace the `Raw` family of types and
|
||||
//! traits.
|
||||
//!
|
||||
//! This API has much conceptual similarity with the `Raw` API, but introduces
|
||||
//! explicit concepts of ownership and borrowing:
|
||||
//!
|
||||
//! | `Raw` API | This experimental API |
|
||||
//! | ---------- | ------------------------ |
|
||||
//! | `Raw*` | `Borrowed*` and `Owned*` |
|
||||
//! | `AsRaw*` | `As*` |
|
||||
//! | `IntoRaw*` | `Into*` |
|
||||
//! | `FromRaw*` | `From*` |
|
||||
//!
|
||||
//! This gives it several advantages:
|
||||
//!
|
||||
//! - Less `unsafe` in user code!
|
||||
//!
|
||||
//! - Easier to understand ownership.
|
||||
//!
|
||||
//! - It avoids the inconsistency where `AsRawFd` and `IntoRawFd` return
|
||||
//! `RawFd` values that users ought to be able to trust, but aren't unsafe,
|
||||
//! so it's possible to fail to uphold this trust in purely safe Rust.
|
||||
//!
|
||||
//! - It enables a number of safe and portable convenience features, such as
|
||||
//! [safe typed views] and [from+into conversions].
|
||||
//!
|
||||
//! [safe typed views]: AsFilelike::as_filelike_view
|

//! [from+into conversions]: FromFilelike::from_into_filelike
