|
||||
|
||||

|
||||
|
||||

||||
and distribution as defined by Sections 1 through 9 of this document.
|

||||
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,

"control" means (i) the power, direct or indirect, to cause the
|
||||
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.
|
||||
|
||||
"Source" form shall mean the preferred form for making modifications,
|
||||
including but not limited to software source code, documentation
|
||||
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.
|
||||
|
||||

||||

||||

# Library charts provide useful utilities or functions for the chart developer. They're included as

Chart documentation is generated with [helm-docs](https://github.com/norwoodj/helm-docs) from `values.yaml` file.
|
||||
After file modification, regenerate README.md with command:
|
||||
|
||||
```bash
|
||||
docker run --rm -it -v $(pwd):/helm --workdir /helm norwoodj/helm-docs helm-docs
|
||||
```
|
||||
|
||||
### Run linter
|
||||
|
||||
```bash
|
||||
docker run --rm -it -w /charts -v $(pwd)/../{{ .Name }}:/charts quay.io/helmpack/chart-testing:v2.4.0 ct lint --charts . --config /charts/ct.yaml
|
||||
```
|
||||
|
||||
### Prometheus Rules
|
||||
|
||||
Check rules:
|
||||
|
||||
```bash
|
||||
docker run --rm --entrypoint /bin/sh -v $(pwd):/workdir -w /workdir prom/prometheus -c -- "promtool check rules resources/prometheus-rules/*"
|

# xxhash
|
||||
|
||||
[](https://pkg.go.dev/github.com/cespare/xxhash/v2)
|
||||
[](https://github.com/cespare/xxhash/actions/workflows/test.yml)
|
||||
|
||||
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'
|
||||
$ go test -benchtime 10s -bench '/xxhash,direct,bytes'
|

## Issues
|
||||
|
||||
* Request features and report bugs using the [GitHub Issue Tracker](https://github.com/fsnotify/fsnotify/issues).
|
||||
* Please indicate the platform you are using fsnotify on.
|
||||
* A code example to reproduce the problem is appreciated.
|
||||
|
||||
## Pull Requests
|
||||
|
||||
### Contributor License Agreement
|
||||
|
||||
fsnotify is derived from code in the [golang.org/x/exp](https://godoc.org/golang.org/x/exp) package and it may be included [in the standard library](https://github.com/fsnotify/fsnotify/issues/1) in the future. Therefore fsnotify carries the same [LICENSE](https://github.com/fsnotify/fsnotify/blob/master/LICENSE) as Go. Contributors retain their copyright, so you need to fill out a short form before we can accept your contribution: [Google Individual Contributor License Agreement](https://developers.google.com/open-source/cla/individual).
|
||||
|
||||
Please indicate that you have signed the CLA in your pull request.
|
||||
|
||||
### How fsnotify is Developed
|
||||
|
||||
* Development is done on feature branches.
|
||||
* Tests are run on BSD, Linux, macOS and Windows.
|
||||
* Pull requests are reviewed and [applied to master][am] using [hub][].
|
||||
* Maintainers may modify or squash commits rather than asking contributors to.
|
||||
* To issue a new release, the maintainers will:
|
||||
* Update the CHANGELOG
|
||||
* Tag a version, which will become available through gopkg.in.
|
||||
|
||||
### How to Fork
|
||||
|
||||
For smooth sailing, always use the original import path. Installing with `go get` makes this easy.
|
||||
|
||||
1. Install from GitHub (`go get -u github.com/fsnotify/fsnotify`)
|
||||
2. Create your feature branch (`git checkout -b my-new-feature`)
|
||||
3. Ensure everything works and the tests pass (see below)
|
||||
4. Commit your changes (`git commit -am 'Add some feature'`)
|
||||
|
||||
Contribute upstream:
|
||||
|
||||
1. Fork fsnotify on GitHub
|
||||
2. Add your remote (`git remote add fork git@github.com:mycompany/repo.git`)
|
||||
3. Push to the branch (`git push fork my-new-feature`)
|
||||
4. Create a new Pull Request on GitHub
|
||||
|
||||
This workflow is [thoroughly explained by Katrina Owen](https://splice.com/blog/contributing-open-source-git-repositories-go/).
|
||||
|
||||
### Testing
|
||||
|
||||
fsnotify uses build tags to compile different code on Linux, BSD, macOS, and Windows.
|
||||
|
||||
Before doing a pull request, please do your best to test your changes on multiple platforms, and list which platforms you were able/unable to test on.
|
||||
|
||||
To aid in cross-platform testing there is a Vagrantfile for Linux and BSD.
|
||||
|
||||
* Install [Vagrant](http://www.vagrantup.com/) and [VirtualBox](https://www.virtualbox.org/)
|
||||
* Setup [Vagrant Gopher](https://github.com/nathany/vagrant-gopher) in your `src` folder.
|
||||
* Run `vagrant up` from the project folder. You can also setup just one box with `vagrant up linux` or `vagrant up bsd` (note: the BSD box doesn't support Windows hosts at this time, and NFS may prompt for your host OS password)
|
||||
* Once setup, you can run the test suite on a given OS with a single command `vagrant ssh linux -c 'cd fsnotify/fsnotify; go test'`.
|
||||
* When you're done, you will want to halt or destroy the Vagrant boxes.
|
||||
|
||||
Notice: fsnotify file system events won't trigger in shared folders. The tests get around this limitation by using the /tmp directory.
|
||||
|
||||
Right now there is no equivalent solution for Windows and macOS, but there are Windows VMs [freely available from Microsoft](http://www.modern.ie/en-us/virtualization-tools#downloads).
|
||||
|
||||
### Maintainers
|
||||
|
||||
Help maintaining fsnotify is welcome. To be a maintainer:
|
||||
|
||||
* Submit a pull request and sign the CLA as above.
|
||||
* You must be able to run the test suite on Mac, Windows, Linux and BSD.
|
||||
|
||||
To keep master clean, the fsnotify project uses the "apply mail" workflow outlined in Nathaniel Talbott's post ["Merge pull request" Considered Harmful][am]. This requires installing [hub][].
|
||||
|
||||
All code changes should be internal pull requests.
|
||||
|
||||
Releases are tagged using [Semantic Versioning](http://semver.org/).

# File system notifications for Go
|
||||
|
||||
[](https://godoc.org/github.com/fsnotify/fsnotify) [](https://goreportcard.com/report/github.com/fsnotify/fsnotify)
|
||||
|
||||
fsnotify utilizes [golang.org/x/sys](https://godoc.org/golang.org/x/sys) rather than `syscall` from the standard library. Ensure you have the latest version installed by running:
|
||||
|
||||
```console
|
||||
go get -u golang.org/x/sys/...
|
||||
```
|
||||
|
||||
Cross platform: Windows, Linux, BSD and macOS.
|
||||
|
||||

|
||||
|
||||
Please see [the documentation](https://godoc.org/github.com/fsnotify/fsnotify) and consult the [FAQ](#faq) for usage information.
|
||||
|
||||
## API stability
|
||||
|
||||
fsnotify is a fork of [howeyc/fsnotify](https://godoc.org/github.com/howeyc/fsnotify) with a new API as of v1.0. The API is based on [this design document](http://goo.gl/MrYxyA).
|
||||
|
||||
All [releases](https://github.com/fsnotify/fsnotify/releases) are tagged based on [Semantic Versioning](http://semver.org/). Further API changes are [planned](https://github.com/fsnotify/fsnotify/milestones), and will be tagged with a new major revision number.
|
||||
|
||||
Go 1.6 supports dependencies located in the `vendor/` folder. Unless you are creating a library, it is recommended that you copy fsnotify into `vendor/github.com/fsnotify/fsnotify` within your project, and likewise for `golang.org/x/sys`.
|
||||
|
||||
## Usage
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"log"
|
||||
|
||||
"github.com/fsnotify/fsnotify"
|
||||
)
|
||||
|
||||
func main() {
|
||||
watcher, err := fsnotify.NewWatcher()
|
||||
if err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
defer watcher.Close()
|
||||
|
||||
done := make(chan bool)
|
||||
go func() {
|
||||
for {
|
||||
select {
|
||||
case event, ok := <-watcher.Events:
|
||||
if !ok {
|
||||
return
|
||||
}
|
||||
log.Println("event:", event)
|
||||
if event.Op&fsnotify.Write == fsnotify.Write {
|
||||
log.Println("modified file:", event.Name)
|
||||
}
|
||||
case err, ok := <-watcher.Errors:
|
||||
if !ok {
|
||||
return
|
||||
}
|
||||
log.Println("error:", err)
|
||||
}
|
||||
}
|
||||
}()
|
||||
|
||||
err = watcher.Add("/tmp/foo")
|
||||
if err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
<-done
|
||||
}
|
||||
```

## FAQ
|
||||
|
||||
**When a file is moved to another directory is it still being watched?**
|
||||
|
||||
No (it shouldn't be, unless you are watching where it was moved to).
|
||||
|
||||
**When I watch a directory, are all subdirectories watched as well?**
|
||||
|
||||
No, you must add watches for any directory you want to watch (a recursive watcher is on the roadmap [#18][]).
|
||||
|
||||
**Do I have to watch the Error and Event channels in a separate goroutine?**
|
||||
|
||||
As of now, yes. Looking into making this single-thread friendly (see [howeyc #7][#7])
|
||||
|
||||
**Why am I receiving multiple events for the same file on OS X?**
|
||||
|
||||
Spotlight indexing on OS X can result in multiple events (see [howeyc #62][#62]). A temporary workaround is to add your folder(s) to the *Spotlight Privacy settings* until we have a native FSEvents implementation (see [#11][]).
|
||||
|
||||
**How many files can be watched at once?**
|
||||
|
||||
There are OS-specific limits as to how many watches can be created:
|
||||
* Linux: /proc/sys/fs/inotify/max_user_watches contains the limit, reaching this limit results in a "no space left on device" error.
|
||||
* BSD / OSX: sysctl variables "kern.maxfiles" and "kern.maxfilesperproc", reaching these limits results in a "too many open files" error.
|
||||
|
||||
**Why don't notifications work with NFS filesystems or filesystem in userspace (FUSE)?**
|
||||
|
||||
fsnotify requires support from underlying OS to work. The current NFS protocol does not provide network level support for file notifications.

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,
|
||||
"control" means (i) the power, direct or indirect, to cause the
|
||||
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.
|
||||
|
||||
"Source" form shall mean the preferred form for making modifications,
|
||||
including but not limited to software source code, documentation
|
||||
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.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
APPENDIX: How to apply the Apache License to your work.
|
||||
|
||||
To apply the Apache License to your work, attach the following
|
||||
boilerplate notice, with the fields enclosed by brackets "{}"
|

|
||||
comment syntax for the file format. We also recommend that a
|
||||
file or class name and description of purpose be included on the
|
||||

# tail functionality in Go
|
||||
|
||||
nxadm/tail provides a Go library that emulates the features of the BSD `tail`
|
||||
program. The library comes with full support for truncation/move detection as
|
||||
it is designed to work with log rotation tools. The library works on all
|
||||
operating systems supported by Go, including POSIX systems like Linux and
|
||||
*BSD, and MS Windows. Go 1.9 is the oldest compiler release supported.
|
||||
|
||||
A simple example:
|
||||
|
||||
```Go
|
||||
// Create a tail
|
||||
t, err := tail.TailFile(
|
||||
"/var/log/nginx.log", tail.Config{Follow: true, ReOpen: true})
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}
|
||||
|
||||
// Print the text of each received line
|
||||
for line := range t.Lines {
|
||||
fmt.Println(line.Text)
|
||||
}
|
||||
```
|
||||
|
||||
See [API documentation](https://pkg.go.dev/github.com/nxadm/tail).
|
||||
|
||||
## Installing
|
||||
|
||||
go get github.com/nxadm/tail/...
|
||||
|
||||
## History
|
||||
|
||||
This project is an active, drop-in replacement for the
|
||||
[abandoned](https://en.wikipedia.org/wiki/HPE_Helion) Go tail library at
|
||||
[hpcloud](https://github.com/hpcloud/tail). Next to
|
||||
[addressing open issues/PRs of the original project](https://github.com/nxadm/tail/issues/6),
|
||||
nxadm/tail continues the development by keeping up to date with the Go toolchain
|
||||
(e.g. go modules) and dependencies, completing the documentation, adding features
|
||||
and fixing bugs.
|
||||
|
||||
## Examples
|
||||
Examples, e.g. used to debug an issue, are kept in the [examples directory](/examples).

"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,

|
||||
"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"
|

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

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
|
||||
|
||||
APPENDIX: How to apply the Apache License to your work.
|
||||
|
||||
To apply the Apache License to your work, attach the following
|
||||
boilerplate notice, with the fields enclosed by brackets "[]"
|
||||
replaced with your own identifying information. (Don't include
|
||||
the brackets!) The text should be enclosed in the appropriate
|
||||
comment syntax for the file format. We also recommend that a
|
||||
file or class name and description of purpose be included on the
|
||||

// Collector is the interface implemented by anything that can be used by
|
||||
// Prometheus to collect metrics. A Collector has to be registered for
|
||||
// collection. See Registerer.Register.
|
||||
//
|
||||
// The stock metrics provided by this package (Gauge, Counter, Summary,
|
||||
// Histogram, Untyped) are also Collectors (which only ever collect one metric,
|
||||
// namely itself). An implementer of Collector may, however, collect multiple
|
||||
// metrics in a coordinated fashion and/or create metrics on the fly. Examples
|
||||
// for collectors already implemented in this library are the metric vectors
|
||||
// (i.e. collection of multiple instances of the same Metric but with different
|
||||
// label values) like GaugeVec or SummaryVec, and the ExpvarCollector.
|
||||
type Collector interface {
|
||||
// Describe sends the super-set of all possible descriptors of metrics
|
||||
// collected by this Collector to the provided channel and returns once
|
||||
// the last descriptor has been sent. The sent descriptors fulfill the
|
||||
// consistency and uniqueness requirements described in the Desc
|
||||
// documentation.
|
||||
//
|
||||
// It is valid if one and the same Collector sends duplicate
|
||||
// descriptors. Those duplicates are simply ignored. However, two
|
||||
// different Collectors must not send duplicate descriptors.
|
||||
//
|
||||
// Sending no descriptor at all marks the Collector as “unchecked”,
|
||||
// i.e. no checks will be performed at registration time, and the
|
||||
// Collector may yield any Metric it sees fit in its Collect method.
|
||||
//
|
||||
// This method idempotently sends the same descriptors throughout the
|
||||
// lifetime of the Collector. It may be called concurrently and
|
||||
// therefore must be implemented in a concurrency safe way.
|
||||
//
|
||||
// If a Collector encounters an error while executing this method, it
|
||||
// must send an invalid descriptor (created with NewInvalidDesc) to
|
||||
// signal the error to the registry.
|
||||
Describe(chan<- *Desc)
|
||||
// Collect is called by the Prometheus registry when collecting
|
||||
// metrics. The implementation sends each collected metric via the
|
||||
// provided channel and returns once the last metric has been sent. The
|
||||
// descriptor of each sent metric is one of those returned by Describe
|
||||
// (unless the Collector is unchecked, see above). Returned metrics that
|
||||
// share the same descriptor must differ in their variable label
|
||||
// values.
|
||||
//
|
||||
// This method may be called concurrently and must therefore be
|
||||
// implemented in a concurrency safe way. Blocking occurs at the expense
|
||||
// of total performance of rendering all registered metrics. Ideally,
|
||||
// Collector implementations support concurrent readers.
|
||||
Collect(chan<- Metric)

|
||||
// DescribeByCollect is a helper to implement the Describe method of a custom
|
||||
// Collector. It collects the metrics from the provided Collector and sends
|
||||
// their descriptors to the provided channel.
|
||||
//
|
||||
// If a Collector collects the same metrics throughout its lifetime, its
|
||||
// Describe method can simply be implemented as:
|
||||
//
|
||||
// func (c customCollector) Describe(ch chan<- *Desc) {
|
||||
// DescribeByCollect(c, ch)
|
||||
// }
|
||||
//
|
||||
// However, this will not work if the metrics collected change dynamically over
|
||||
// the lifetime of the Collector in a way that their combined set of descriptors
|
||||
