Code Issues Proposed changes

add isolcpus device plugin for kubernetes

Browse Source 
In order to minimize latency as much as possible, we want to allow
kubernetes containers to make use of CPUs which have been specified
as "isolated" via the kernel boot args.

This commit creates an isolcpus device plugin, which detects the isolated
CPUs and exports them to kubelet via the device plugin API.

See kubernetes/plugins/isolcpus-device-plugin/files/README.md for
more information on the behaviour and design choices for this commit.

When we move to a newer version of the Intel device plugin manager we
may be able to simplify some of this.  See the above README.md file
for details.

# Isolated CPUs Device Plugin for Kubernetes
## About
This code implements a Kubernetes device plugin. The plugin detects all CPUs
specified via "isolcpus=X" in the kernel boot args, and exports them to
Kubernetes as custom devices using the deviceplugin API.
It makes heavy use of the Intel device plugin manager from github.com/intel/intel-device-plugins-for-kubernetes
and credit is due to them for making a useful helper. A good example of how
to use that framework can be found at
https://github.com/intel/intel-device-plugins-for-kubernetes/blob/master/cmd/gpu_plugin/gpu_plugin.go
## Implementation Notes
There are currently problems with using go modules for the deviceplugin API...it
leads to an "go: error loading module requirements" error when running "go build".
Accordingly, it was necessary to copy a number of files from external packages.
As part of this work I also updated the deviceplugin API files to the latest
versions to pick up in-development upstream changes.
The "intel/intel-device-plugins-for-kubernetes" subdirectory corresponds to
"github.com/intel/intel-device-plugins-for-kubernetes".
The "kubernetes" subdirectory corresponds to "k8s.io/kubernetes"
In an ideal world, these two subdirectories would not be needed, and instead we
would simply include the following imports in isolcpu.go:
"github.com/intel/intel-device-plugins-for-kubernetes/pkg/debug"
dpapi "github.com/intel/intel-device-plugins-for-kubernetes/pkg/deviceplugin"
pluginapi "k8s.io/kubernetes/pkg/kubelet/apis/deviceplugin/v1beta1"
"k8s.io/kubernetes/pkg/kubelet/cm/cpuset"
This would also require updating the Intel package to pick up the latest
deviceplugin API so that the topology field is properly represented.
## Build Notes
In order to avoid the need for a network connection to download dependencies
at build time, I've chosen to include all the dependencies in the "vendor"
directory. This is auto-generated by running "go mod vendor". The binary
is then built with "go build -mod=vendor".

* 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
[![GoDoc](https://godoc.org/github.com/fsnotify/fsnotify?status.svg)](https://godoc.org/github.com/fsnotify/fsnotify) [![Go Report Card](https://goreportcard.com/badge/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`.

## Example

## 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.

Package gogoproto provides extensions for protocol buffers to achieve:
- fast marshalling and unmarshalling.
- peace of mind by optionally generating test and benchmark code.
- more canonical Go structures.
- less typing by optionally generating extra helper code.
- goprotobuf compatibility
More Canonical Go Structures
A lot of time working with a goprotobuf struct will lead you to a place where you create another struct that is easier to work with and then have a function to copy the values between the two structs.
You might also find that basic structs that started their life as part of an API need to be sent over the wire. With gob, you could just send it. With goprotobuf, you need to make a parallel struct.
Gogoprotobuf tries to fix these problems with the nullable, embed, customtype and customname field extensions.
- nullable, if false, a field is generated without a pointer (see warning below).
- embed, if true, the field is generated as an embedded field.
- customtype, It works with the Marshal and Unmarshal methods, to allow you to have your own types in your struct, but marshal to bytes. For example, custom.Uuid or custom.Fixed128
- customname (beta), Changes the generated fieldname. This is especially useful when generated methods conflict with fieldnames.
- casttype (beta), Changes the generated fieldtype. All generated code assumes that this type is castable to the protocol buffer field type. It does not work for structs or enums.
- castkey (beta), Changes the generated fieldtype for a map key. All generated code assumes that this type is castable to the protocol buffer field type. Only supported on maps.
- castvalue (beta), Changes the generated fieldtype for a map value. All generated code assumes that this type is castable to the protocol buffer field type. Only supported on maps.
Warning about nullable: According to the Protocol Buffer specification, you should be able to tell whether a field is set or unset. With the option nullable=false this feature is lost, since your non-nullable fields will always be set. It can be seen as a layer on top of Protocol Buffers, where before and after marshalling all non-nullable fields are set and they cannot be unset.
Let us look at:
github.com/gogo/protobuf/test/example/example.proto
for a quicker overview.
The following message:
package test;
import "github.com/gogo/protobuf/gogoproto/gogo.proto";
message A {
optional string Description = 1 [(gogoproto.nullable) = false];
optional int64 Number = 2 [(gogoproto.nullable) = false];
optional bytes Id = 3 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uuid", (gogoproto.nullable) = false];
}
Will generate a go struct which looks a lot like this:
type A struct {
Description string
Number int64
Id github_com_gogo_protobuf_test_custom.Uuid
}
You will see there are no pointers, since all fields are non-nullable.
You will also see a custom type which marshals to a string.
Be warned it is your responsibility to test your custom types thoroughly.
You should think of every possible empty and nil case for your marshaling, unmarshaling and size methods.
Next we will embed the message A in message B.
message B {
optional A A = 1 [(gogoproto.nullable) = false, (gogoproto.embed) = true];
repeated bytes G = 2 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uint128", (gogoproto.nullable) = false];
}
See below that A is embedded in B.
type B struct {
A
G []github_com_gogo_protobuf_test_custom.Uint128
}
Also see the repeated custom type.
type Uint128 [2]uint64
Next we will create a custom name for one of our fields.
message C {
optional int64 size = 1 [(gogoproto.customname) = "MySize"];
}
See below that the field's name is MySize and not Size.
type C struct {
MySize *int64
}
The is useful when having a protocol buffer message with a field name which conflicts with a generated method.
As an example, having a field name size and using the sizer plugin to generate a Size method will cause a go compiler error.
Using customname you can fix this error without changing the field name.
This is typically useful when working with a protocol buffer that was designed before these methods and/or the go language were avialable.
Gogoprotobuf also has some more subtle changes, these could be changed back:
- the generated package name for imports do not have the extra /filename.pb,
but are actually the imports specified in the .proto file.
Gogoprotobuf also has lost some features which should be brought back with time:
- Marshalling and unmarshalling with reflect and without the unsafe package,
this requires work in pointer_reflect.go
Why does nullable break protocol buffer specifications:
The protocol buffer specification states, somewhere, that you should be able to tell whether a
field is set or unset. With the option nullable=false this feature is lost,
since your non-nullable fields will always be set. It can be seen as a layer on top of
protocol buffers, where before and after marshalling all non-nullable fields are set
and they cannot be unset.
Goprotobuf Compatibility:
Gogoprotobuf is compatible with Goprotobuf, because it is compatible with protocol buffers.
Gogoprotobuf generates the same code as goprotobuf if no extensions are used.
The enumprefix, getters and stringer extensions can be used to remove some of the unnecessary code generated by goprotobuf:
- gogoproto_import, if false, the generated code imports github.com/golang/protobuf/proto instead of github.com/gogo/protobuf/proto.
- goproto_enum_prefix, if false, generates the enum constant names without the messagetype prefix
- goproto_enum_stringer (experimental), if false, the enum is generated without the default string method, this is useful for rather using enum_stringer, or allowing you to write your own string method.
- goproto_getters, if false, the message is generated without get methods, this is useful when you would rather want to use face
- goproto_stringer, if false, the message is generated without the default string method, this is useful for rather using stringer, or allowing you to write your own string method.
- goproto_extensions_map (beta), if false, the extensions field is generated as type []byte instead of type map[int32]proto.Extension
- goproto_unrecognized (beta), if false, XXX_unrecognized field is not generated. This is useful in conjunction with gogoproto.nullable=false, to generate structures completely devoid of pointers and reduce GC pressure at the cost of losing information about unrecognized fields.
- goproto_registration (beta), if true, the generated files will register all messages and types against both gogo/protobuf and golang/protobuf. This is necessary when using third-party packages which read registrations from golang/protobuf (such as the grpc-gateway).
Less Typing and Peace of Mind is explained in their specific plugin folders godoc:
- github.com/gogo/protobuf/plugin/<extension_name>
If you do not use any of these extension the code that is generated
will be the same as if goprotobuf has generated it.
The most complete way to see examples is to look at
github.com/gogo/protobuf/test/thetest.proto
Gogoprototest is a seperate project,
because we want to keep gogoprotobuf independent of goprotobuf,
but we still want to test it thoroughly.

Equal returns true iff protocol buffers a and b are equal.
The arguments must both be pointers to protocol buffer structs.
Equality is defined in this way:
- Two messages are equal iff they are the same type,
corresponding fields are equal, unknown field sets
are equal, and extensions sets are equal.
- Two set scalar fields are equal iff their values are equal.
If the fields are of a floating-point type, remember that
NaN != x for all x, including NaN. If the message is defined
in a proto3 .proto file, fields are not "set"; specifically,
zero length proto3 "bytes" fields are equal (nil == {}).
- Two repeated fields are equal iff their lengths are the same,
and their corresponding elements are equal. Note a "bytes" field,
although represented by []byte, is not a repeated field and the
rule for the scalar fields described above applies.
- Two unset fields are equal.
- Two unknown field sets are equal if their current
encoded state is equal.
- Two extension sets are equal iff they have corresponding
elements that are pairwise equal.
- Two map fields are equal iff their lengths are the same,
and they contain the same set of elements. Zero-length map
fields are equal.
- Every other combination of things are not equal.
The return value is undefined if a and b are not protocol buffers.

Package proto converts data structures to and from the wire format of
protocol buffers. It works in concert with the Go source code generated
for .proto files by the protocol compiler.
A summary of the properties of the protocol buffer interface
for a protocol buffer variable v:
- Names are turned from camel_case to CamelCase for export.
- There are no methods on v to set fields; just treat
them as structure fields.
- There are getters that return a field's value if set,
and return the field's default value if unset.
The getters work even if the receiver is a nil message.
- The zero value for a struct is its correct initialization state.
All desired fields must be set before marshaling.
- A Reset() method will restore a protobuf struct to its zero state.
- Non-repeated fields are pointers to the values; nil means unset.
That is, optional or required field int32 f becomes F *int32.
- Repeated fields are slices.
- Helper functions are available to aid the setting of fields.
msg.Foo = proto.String("hello") // set field
- Constants are defined to hold the default values of all fields that
have them. They have the form Default_StructName_FieldName.
Because the getter methods handle defaulted values,
direct use of these constants should be rare.
- Enums are given type names and maps from names to values.
Enum values are prefixed by the enclosing message's name, or by the
enum's type name if it is a top-level enum. Enum types have a String
method, and a Enum method to assist in message construction.
- Nested messages, groups and enums have type names prefixed with the name of
the surrounding message type.
- Extensions are given descriptor names that start with E_,
followed by an underscore-delimited list of the nested messages
that contain it (if any) followed by the CamelCased name of the
extension field itself. HasExtension, ClearExtension, GetExtension
and SetExtension are functions for manipulating extensions.
- Oneof field sets are given a single field in their message,
with distinguished wrapper types for each possible field value.
- Marshal and Unmarshal are functions to encode and decode the wire format.
When the .proto file specifies `syntax="proto3"`, there are some differences:
- Non-repeated fields of non-message type are values instead of pointers.
- Enum types do not get an Enum method.
The simplest way to describe this is to see an example.
Given file test.proto, containing
package example;
enum FOO { X = 17; }
message Test {
required string label = 1;
optional int32 type = 2 [default=77];
repeated int64 reps = 3;
optional group OptionalGroup = 4 {

oneof union {

If the fields are of a floating-point type, remember that
NaN != x for all x, including NaN. If the message is defined
in a proto3 .proto file, fields are not "set"; specifically,
zero length proto3 "bytes" fields are equal (nil == {}).
- Two repeated fields are equal iff their lengths are the same,
and their corresponding elements are equal. Note a "bytes" field,
although represented by []byte, is not a repeated field and the
rule for the scalar fields described above applies.
- Two unset fields are equal.
- Two unknown field sets are equal if their current
encoded state is equal.
- Two extension sets are equal iff they have corresponding
elements that are pairwise equal.
- Two map fields are equal iff their lengths are the same,
and they contain the same set of elements. Zero-length map
fields are equal.
- Every other combination of things are not equal.
The return value is undefined if a and b are not protocol buffers.

/*
Package proto converts data structures to and from the wire format of
protocol buffers. It works in concert with the Go source code generated
for .proto files by the protocol compiler.
A summary of the properties of the protocol buffer interface
for a protocol buffer variable v:
- Names are turned from camel_case to CamelCase for export.
- There are no methods on v to set fields; just treat
them as structure fields.
- There are getters that return a field's value if set,
and return the field's default value if unset.
The getters work even if the receiver is a nil message.
- The zero value for a struct is its correct initialization state.
All desired fields must be set before marshaling.
- A Reset() method will restore a protobuf struct to its zero state.
- Non-repeated fields are pointers to the values; nil means unset.
That is, optional or required field int32 f becomes F *int32.
- Repeated fields are slices.
- Helper functions are available to aid the setting of fields.
msg.Foo = proto.String("hello") // set field
- Constants are defined to hold the default values of all fields that
have them. They have the form Default_StructName_FieldName.
Because the getter methods handle defaulted values,
direct use of these constants should be rare.
- Enums are given type names and maps from names to values.
Enum values are prefixed by the enclosing message's name, or by the
enum's type name if it is a top-level enum. Enum types have a String
method, and a Enum method to assist in message construction.
- Nested messages, groups and enums have type names prefixed with the name of
the surrounding message type.
- Extensions are given descriptor names that start with E_,
followed by an underscore-delimited list of the nested messages
that contain it (if any) followed by the CamelCased name of the
extension field itself. HasExtension, ClearExtension, GetExtension
and SetExtension are functions for manipulating extensions.
- Oneof field sets are given a single field in their message,
with distinguished wrapper types for each possible field value.
- Marshal and Unmarshal are functions to encode and decode the wire format.
When the .proto file specifies `syntax="proto3"`, there are some differences:
- Non-repeated fields of non-message type are values instead of pointers.
- Enum types do not get an Enum method.
The simplest way to describe this is to see an example.
Given file test.proto, containing
package example;
enum FOO { X = 17; }
message Test {
required string label = 1;
optional int32 type = 2 [default=77];
