||||
otherwise, or (ii) ownership of fifty percent (50%) or more of the

|
||||
|
||||
"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.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||

|
||||

Caddy is a **production-ready** open-source web server that is fast, easy to use, and makes you more productive.
|
||||
|
||||
Available for Windows, Mac, Linux, BSD, Solaris, and [Android](https://github.com/caddyserver/caddy/wiki/Running-Caddy-on-Android).

## Features
|
||||
|
||||
- **Easy configuration** with the Caddyfile
|
||||
- **Automatic HTTPS** on by default (via [Let's Encrypt](https://letsencrypt.org))
|
||||
- **HTTP/2** by default
|
||||
- **Virtual hosting** so multiple sites just work
|
||||
- Experimental **QUIC support** for cutting-edge transmissions
|
||||
- TLS session ticket **key rotation** for more secure connections
|
||||
- **Extensible with plugins** because a convenient web server is a helpful one
|
||||
- **Runs anywhere** with **no external dependencies** (not even libc)
|
||||
|
||||
[See a more complete list of features built into Caddy.](https://caddyserver.com/features) On top of all those, Caddy does even more with plugins: choose which plugins you want at [download](https://caddyserver.com/download).
|
||||
|
||||
Altogether, Caddy can do things other web servers simply cannot do. Its features and plugins save you time and mistakes, and will cheer you up. Your Caddy instance takes care of the details for you!

## Install
|
||||
|
||||
Caddy binaries have no dependencies and are available for every platform. Get Caddy any of these ways:
|
||||
|
||||
- **[Download page](https://caddyserver.com/download)** (RECOMMENDED) allows you to customize your build in the browser
|
||||
- **[Latest release](https://github.com/caddyserver/caddy/releases/latest)** for pre-built, vanilla binaries
|
||||
- **[AWS Marketplace](https://aws.amazon.com/marketplace/pp/B07J1WNK75?qid=1539015041932&sr=0-1&ref_=srh_res_product_title&cl_spe=C)** makes it easy to deploy directly to your cloud environment. <a href="https://aws.amazon.com/marketplace/pp/B07J1WNK75?qid=1539015041932&sr=0-1&ref_=srh_res_product_title&cl_spe=C" target="_blank">
|
||||
<img src="https://s3.amazonaws.com/cloudformation-examples/cloudformation-launch-stack.png" alt="Get Caddy on the AWS Marketplace" height="25"/></a>
|
||||
|
||||
|
||||
## Build
|
||||
|
||||
To build from source you need **[Git](https://git-scm.com/downloads)** and **[Go](https://golang.org/doc/install)** (1.13 or newer).
|
||||
|
||||
**To build Caddy without plugins:**
|
||||
|
||||
- Run `go get github.com/caddyserver/caddy/caddy`
|
||||
|
||||
Caddy will be installed to your `$GOPATH/bin` folder.
|
||||
|
||||
With these instructions, the binary will not have embedded version information (see [golang/go#29228](https://github.com/golang/go/issues/29228)), but it is fine for a quick start.
|
||||
|
||||
**To build Caddy with plugins (and with version information):**
|
||||
|
||||
There is no need to modify the Caddy code to build it with plugins. We will create a simple Go module with our own `main()` that you can use to make custom Caddy builds.
|
||||
- Create a new folder anywhere and within create a Go file (with an extension of `.go`, such as `main.go`) with the contents below, adjusting to import the plugins you want to include:
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"github.com/caddyserver/caddy/caddy/caddymain"
|
||||
|
||||
// plug in plugins here, for example:
|
||||
// _ "import/path/here"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// optional: disable telemetry
|
||||
// caddymain.EnableTelemetry = false
|
||||
caddymain.Run()
|
||||
}
|
||||
```
|
||||
3. `go mod init caddy`
|
||||
4. Run `go get github.com/caddyserver/caddy`
|
||||
5. `go install` will then create your binary at `$GOPATH/bin`, or `go build` will put it in the current directory.
|
||||
|
||||
**To install Caddy's source code for development:**
|
||||
|
||||
- Run `git clone https://github.com/caddyserver/caddy.git` in any folder (doesn't have to be in GOPATH).
|
||||
|
||||
You can make changes to the source code from that clone and checkout any commit or tag you wish to develop on.
|
||||
|
||||
When building from source, telemetry is enabled by default. You can disable it by changing `caddymain.EnableTelemetry = false` in run.go, or use the `-disabled-metrics` flag at runtime to disable only certain metrics.
|
||||
|
||||
|
||||
## Quick Start
|
||||
|
||||
To serve static files from the current working directory, run:
|
||||
|
||||
```
|
||||
caddy
|
||||
```
|
||||
|
||||
Caddy's default port is 2015, so open your browser to [http://localhost:2015](http://localhost:2015).
|
||||
|
||||
### Go from 0 to HTTPS in 5 seconds
|
||||
|
||||
If the `caddy` binary has permission to bind to low ports and your domain name's DNS records point to the machine you're on:
|
||||
|
||||
```
|
||||
caddy -host example.com
|
||||
```
|
||||
|
||||
This command serves static files from the current directory over HTTPS. Certificates are automatically obtained and renewed for you! Caddy is also automatically configuring ports 80 and 443 for you, and redirecting HTTP to HTTPS. Cool, huh?
|
||||
|
||||
### Customizing your site
|
||||
|
||||
To customize how your site is served, create a file named Caddyfile by your site and paste this into it:
|
||||
|
||||
```plain
|
||||
localhost
|
||||
|
||||
push
|
||||
browse
|
||||
websocket /echo cat
|
||||
ext .html
|
||||
log /var/log/access.log
|
||||
proxy /api 127.0.0.1:7005
|
||||
header /api Access-Control-Allow-Origin *
|
||||
```
|
||||
|
||||
When you run `caddy` in that directory, it will automatically find and use that Caddyfile.
|
||||
|
||||
This simple file enables server push (via Link headers), allows directory browsing (for folders without an index file), hosts a WebSocket echo server at /echo, serves clean URLs, logs requests to an access log, proxies all API requests to a backend on port 7005, and adds the coveted `Access-Control-Allow-Origin: *` header for all responses from the API.
|
||||
|
||||
Wow! Caddy can do a lot with just a few lines.
|
||||
|
||||
### Doing more with Caddy
|
||||
|
||||
To host multiple sites and do more with the Caddyfile, please see the [Caddyfile tutorial](https://caddyserver.com/tutorial/caddyfile).
|
||||
|
||||
Sites with qualifying hostnames are served over [HTTPS by default](https://caddyserver.com/docs/automatic-https).
|
||||
|
||||
Caddy has a nice little command line interface. Run `caddy -h` to view basic help or see the [CLI documentation](https://caddyserver.com/docs/cli) for details.
|
||||
|
||||
|
||||
## Running in Production
|
||||
|
||||
Caddy is production-ready if you find it to be a good fit for your site and workflow.
|
||||
|
||||
**Running as root:** We advise against this. You can still listen on ports < 1024 on Linux using setcap like so: `sudo setcap cap_net_bind_service=+ep ./caddy`
|
||||
|
||||
The Caddy project does not officially maintain any system-specific integrations nor suggest how to administer your own system. But your download file includes [unofficial resources](https://github.com/caddyserver/caddy/tree/master/dist/init) contributed by the community that you may find helpful for running Caddy in production.
|
||||
|
||||
How you choose to run Caddy is up to you. Many users are satisfied with `nohup caddy &`. Others use `screen`. Users who need Caddy to come back up after reboots either do so in the script that caused the reboot, add a command to an init script, or configure a service with their OS.
|
||||
|
||||
If you have questions or concerns about Caddy' underlying crypto implementations, consult Go's [crypto packages](https://golang.org/pkg/crypto), starting with their documentation, then issues, then the code itself; as Caddy uses mainly those libraries.

## About the Project
|
||||
|
||||
Caddy was born out of the need for a "batteries-included" web server that runs anywhere and doesn't have to take its configuration with it. Caddy took inspiration from [spark](https://github.com/rif/spark), [nginx](https://github.com/nginx/nginx), lighttpd,
|
||||
[Websocketd](https://github.com/joewalnes/websocketd) and [Vagrant](https://www.vagrantup.com/), which provides a pleasant mixture of features from each of them.
|
||||
|
||||
**The name "Caddy" is trademarked:** The name of the software is "Caddy", not "Caddy Server" or "CaddyServer". Please call it "Caddy" or, if you wish to clarify, "the Caddy web server". See [brand guidelines](https://caddyserver.com/brand). Caddy is a registered trademark of Light Code Labs, LLC.

# xxhash
|
||||
|

[](https://godoc.org/github.com/cespare/xxhash)
|

|
||||
|
||||
xxhash is a Go implementation of the 64-bit
|
||||
[xxHash](http://cyan4973.github.io/xxHash/) algorithm, XXH64. This is a
|
||||
high-quality hashing algorithm that is much faster than anything in the Go
|
||||
standard library.
|
||||
|
||||
This package provides a straightforward API:
|
||||
|
||||
```
|
||||
func Sum64(b []byte) uint64
|
||||
func Sum64String(s string) uint64
|
||||
type Digest struct{ ... }
|
||||
func New() *Digest
|
||||
```
|
||||
|
||||
The `Digest` type implements hash.Hash64. Its key methods are:
|
||||
|
||||
```
|
||||
func (*Digest) Write([]byte) (int, error)
|
||||
func (*Digest) WriteString(string) (int, error)
|
||||
func (*Digest) Sum64() uint64
|
||||
```
|
||||
|
||||
This implementation provides a fast pure-Go implementation and an even faster
|
||||
assembly implementation for amd64.
|
||||
|
||||
## Compatibility
|
||||
|
||||
This package is in a module and the latest code is in version 2 of the module.
|
||||
You need a version of Go with at least "minimal module compatibility" to use
|
||||
github.com/cespare/xxhash/v2:
|
||||
|
||||
* 1.9.7+ for Go 1.9
|
||||
* 1.10.3+ for Go 1.10
|
||||
* Go 1.11 or later
|
||||
|
||||
I recommend using the latest release of Go.
|
||||
|
||||
## Benchmarks
|
||||
|
||||
Here are some quick benchmarks comparing the pure-Go and assembly
|
||||
implementations of Sum64.

These numbers were generated on Ubuntu 18.04 with an Intel i7-8700K CPU using
|
||||
the following commands under Go 1.11.2:

```
|

$ go test -tags purego -benchtime 10s -bench '/xxhash,direct,bytes'
|

"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|

|
||||
"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
|

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,
|

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.

||||

||||

||||
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.

||||
