bazil.org/fuse -- Filesystems in Go
===================================
`bazil.org/fuse` is a Go library for writing FUSE userspace
filesystems.
It is a from-scratch implementation of the kernel-userspace
communication protocol, and does not use the C library from the
project called FUSE. `bazil.org/fuse` embraces Go fully for safety and
ease of programming.
Here’s how to get going:
go get bazil.org/fuse
Website: http://bazil.org/fuse/
Github repository: https://github.com/bazil/fuse
API docs: http://godoc.org/bazil.org/fuse
Our thanks to Russ Cox for his fuse library, which this project is
based on.

/*
Package pipeline implements an HTTP request/response middleware pipeline whose
policy objects mutate an HTTP request's URL, query parameters, and/or headers before
the request is sent over the wire.
Not all policy objects mutate an HTTP request; some policy objects simply impact the
flow of requests/responses by performing operations such as logging, retry policies,
timeouts, failure injection, and deserialization of response payloads.
Implementing the Policy Interface
To implement a policy, define a struct that implements the pipeline.Policy interface's Do method. Your Do
method is called when an HTTP request wants to be sent over the network. Your Do method can perform any
operation(s) it desires. For example, it can log the outgoing request, mutate the URL, headers, and/or query
parameters, inject a failure, etc. Your Do method must then forward the HTTP request to next Policy object
in a linked-list ensuring that the remaining Policy objects perform their work. Ultimately, the last Policy
object sends the HTTP request over the network (by calling the HTTPSender's Do method).
When an HTTP response comes back, each Policy object in the linked-list gets a chance to process the response
(in reverse order). The Policy object can log the response, retry the operation if due to a transient failure
or timeout, deserialize the response body, etc. Ultimately, the last Policy object returns the HTTP response
to the code that initiated the original HTTP request.
Here is a template for how to define a pipeline.Policy object:
type myPolicy struct {
node PolicyNode
// TODO: Add configuration/setting fields here (if desired)...
}
func (p *myPolicy) Do(ctx context.Context, request pipeline.Request) (pipeline.Response, error) {
// TODO: Mutate/process the HTTP request here...
response, err := p.node.Do(ctx, request) // Forward HTTP request to next Policy & get HTTP response
// TODO: Mutate/process the HTTP response here...
return response, err // Return response/error to previous Policy
}
Implementing the Factory Interface
Each Policy struct definition requires a factory struct definition that implements the pipeline.Factory interface's New
method. The New method is called when application code wants to initiate a new HTTP request. Factory's New method is
passed a pipeline.PolicyNode object which contains a reference to the owning pipeline.Pipeline object (discussed later) and
a reference to the next Policy object in the linked list. The New method should create its corresponding Policy object
passing it the PolicyNode and any other configuration/settings fields appropriate for the specific Policy object.
Here is a template for how to define a pipeline.Policy object:
// NOTE: Once created & initialized, Factory objects should be goroutine-safe (ex: immutable);
// this allows reuse (efficient use of memory) and makes these objects usable by multiple goroutines concurrently.
type myPolicyFactory struct {
// TODO: Add any configuration/setting fields if desired...
}
func (f *myPolicyFactory) New(node pipeline.PolicyNode) Policy {
return &myPolicy{node: node} // TODO: Also initialize any configuration/setting fields here (if desired)...
}
Using your Factory and Policy objects via a Pipeline
To use the Factory and Policy objects, an application constructs a slice of Factory objects and passes
this slice to the pipeline.NewPipeline function.
func NewPipeline(factories []pipeline.Factory, sender pipeline.HTTPSender) Pipeline
This function also requires an object implementing the HTTPSender interface. For simple scenarios,
passing nil for HTTPSender causes a standard Go http.Client object to be created and used to actually
send the HTTP response over the network. For more advanced scenarios, you can pass your own HTTPSender
object in. This allows sharing of http.Client objects or the use of custom-configured http.Client objects
or other objects that can simulate the network requests for testing purposes.
Now that you have a pipeline.Pipeline object, you can create a pipeline.Request object (which is a simple
wrapper around Go's standard http.Request object) and pass it to Pipeline's Do method along with passing a
context.Context for cancelling the HTTP request (if desired).
type Pipeline interface {
Do(ctx context.Context, methodFactory pipeline.Factory, request pipeline.Request) (pipeline.Response, error)
}
Do iterates over the slice of Factory objects and tells each one to create its corresponding
Policy object. After the linked-list of Policy objects have been created, Do calls the first
Policy object passing it the Context & HTTP request parameters. These parameters now flow through
all the Policy objects giving each object a chance to look at and/or mutate the HTTP request.
The last Policy object sends the message over the network.
When the network operation completes, the HTTP response and error return values pass
back through the same Policy objects in reverse order. Most Policy objects ignore the
response/error but some log the result, retry the operation (depending on the exact
reason the operation failed), or deserialize the response's body. Your own Policy
objects can do whatever they like when processing outgoing requests or incoming responses.
Note that after an I/O request runs to completion, the Policy objects for that request
are garbage collected. However, Pipeline object (like Factory objects) are goroutine-safe allowing
them to be created once and reused over many I/O operations. This allows for efficient use of
memory and also makes them safely usable by multiple goroutines concurrently.
Inserting a Method-Specific Factory into the Linked-List of Policy Objects
While Pipeline and Factory objects can be reused over many different operations, it is
common to have special behavior for a specific operation/method. For example, a method
may need to deserialize the response's body to an instance of a specific data type.
To accommodate this, the Pipeline's Do method takes an additional method-specific
Factory object. The Do method tells this Factory to create a Policy object and
injects this method-specific Policy object into the linked-list of Policy objects.
When creating a Pipeline object, the slice of Factory objects passed must have 1
(and only 1) entry marking where the method-specific Factory should be injected.
The Factory marker is obtained by calling the pipeline.MethodFactoryMarker() function:
func MethodFactoryMarker() pipeline.Factory
Creating an HTTP Request Object
The HTTP request object passed to Pipeline's Do method is not Go's http.Request struct.
Instead, it is a pipeline.Request struct which is a simple wrapper around Go's standard
http.Request. You create a pipeline.Request object by calling the pipeline.NewRequest function:
func NewRequest(method string, url url.URL, options pipeline.RequestOptions) (request pipeline.Request, err error)
To this function, you must pass a pipeline.RequestOptions that looks like this:
type RequestOptions struct {
// The readable and seekable stream to be sent to the server as the request's body.
Body io.ReadSeeker
// The callback method (if not nil) to be invoked to report progress as the stream is uploaded in the HTTP request.
Progress ProgressReceiver
}
The method and struct ensure that the request's body stream is a read/seekable stream.
A seekable stream is required so that upon retry, the final Policy object can seek
the stream back to the beginning before retrying the network request and re-uploading the
body. In addition, you can associate a ProgressReceiver callback function which will be
invoked periodically to report progress while bytes are being read from the body stream
and sent over the network.
Processing the HTTP Response
When an HTTP response comes in from the network, a reference to Go's http.Response struct is
embedded in a struct that implements the pipeline.Response interface:
type Response interface {
Response() *http.Response
}
This interface is returned through all the Policy objects. Each Policy object can call the Response
interface's Response method to examine (or mutate) the embedded http.Response object.
A Policy object can internally define another struct (implementing the pipeline.Response interface)
that embeds an http.Response and adds additional fields and return this structure to other Policy
objects. This allows a Policy object to deserialize the body to some other struct and return the
original http.Response and the additional struct back through the Policy chain. Other Policy objects
can see the Response but cannot see the additional struct with the deserialized body. After all the
Policy objects have returned, the pipeline.Response interface is returned by Pipeline's Do method.
The caller of this method can perform a type assertion attempting to get back to the struct type
really returned by the Policy object. If the type assertion is successful, the caller now has
access to both the http.Response and the deserialized struct object.*/

/*
Package azblob allows you to manipulate Azure Storage containers and blobs objects.
URL Types
The most common types you'll work with are the XxxURL types. The methods of these types make requests
against the Azure Storage Service.
- ServiceURL's methods perform operations on a storage account.
- ContainerURL's methods perform operations on an account's container.
- BlockBlobURL's methods perform operations on a container's block blob.
- AppendBlobURL's methods perform operations on a container's append blob.
- PageBlobURL's methods perform operations on a container's page blob.
- BlobURL's methods perform operations on a container's blob regardless of the blob's type.
Internally, each XxxURL object contains a URL and a request pipeline. The URL indicates the endpoint where each HTTP
request is sent and the pipeline indicates how the outgoing HTTP request and incoming HTTP response is processed.
The pipeline specifies things like retry policies, logging, deserialization of HTTP response payloads, and more.
Pipelines are threadsafe and may be shared by multiple XxxURL objects. When you create a ServiceURL, you pass
an initial pipeline. When you call ServiceURL's NewContainerURL method, the new ContainerURL object has its own
URL but it shares the same pipeline as the parent ServiceURL object.
To work with a blob, call one of ContainerURL's 4 NewXxxBlobURL methods depending on how you want to treat the blob.
To treat the blob as a block blob, append blob, or page blob, call NewBlockBlobURL, NewAppendBlobURL, or NewPageBlobURL
respectively. These three types are all identical except for the methods they expose; each type exposes the methods
relevant to the type of blob represented. If you're not sure how you want to treat a blob, you can call NewBlobURL;
this returns an object whose methods are relevant to any kind of blob. When you call ContainerURL's NewXxxBlobURL,
the new XxxBlobURL object has its own URL but it shares the same pipeline as the parent ContainerURL object. You
can easily switch between blob types (method sets) by calling a ToXxxBlobURL method.
If you'd like to use a different pipeline with a ServiceURL, ContainerURL, or XxxBlobURL object, then call the XxxURL
object's WithPipeline method passing in the desired pipeline. The WithPipeline methods create a new XxxURL object
with the same URL as the original but with the specified pipeline.
Note that XxxURL objects use little memory, are goroutine-safe, and many objects share the same pipeline. This means that
XxxURL objects share a lot of system resources making them very efficient.
All of XxxURL's methods that make HTTP requests return rich error handling information so you can discern network failures,
transient failures, timeout failures, service failures, etc. See the StorageError interface for more information and an
example of how to do deal with errors.
URL and Shared Access Signature Manipulation
The library includes a BlobURLParts type for deconstructing and reconstructing URLs. And you can use the following types
for generating and parsing Shared Access Signature (SAS)
- Use the AccountSASSignatureValues type to create a SAS for a storage account.
- Use the BlobSASSignatureValues type to create a SAS for a container or blob.
- Use the SASQueryParameters type to turn signature values in to query parameres or to parse query parameters.
To generate a SAS, you must use the SharedKeyCredential type.
Credentials
When creating a request pipeline, you must specify one of this package's credential types.
- Call the NewAnonymousCredential function for requests that contain a Shared Access Signature (SAS).
- Call the NewSharedKeyCredential function (with an account name & key) to access any account resources. You must also use this
to generate Shared Access Signatures.
HTTP Request Policy Factories
This package defines several request policy factories for use with the pipeline package.
Most applications will not use these factories directly; instead, the NewPipeline
function creates these factories, initializes them (via the PipelineOptions type)
and returns a pipeline object for use by the XxxURL objects.
However, for advanced scenarios, developers can access these policy factories directly
and even create their own and then construct their own pipeline in order to affect HTTP
requests and responses performed by the XxxURL objects. For example, developers can
introduce their own logging, random failures, request recording & playback for fast
testing, HTTP request pacing, alternate retry mechanisms, metering, metrics, etc. The
possibilities are endless!
Below are the request pipeline policy factory functions that are provided with this
package:
- NewRetryPolicyFactory Enables rich retry semantics for failed HTTP requests.
- NewRequestLogPolicyFactory Enables rich logging support for HTTP requests/responses & failures.
- NewTelemetryPolicyFactory Enables simple modification of the HTTP request's User-Agent header so each request reports the SDK version & language/runtime making the requests.
- NewUniqueRequestIDPolicyFactory Adds a x-ms-client-request-id header with a unique UUID value to an HTTP request to help with diagnosing failures.
Also, note that all the NewXxxCredential functions return request policy factory objects which get injected into the pipeline.

goconfig [![Go Walker](http://gowalker.org/api/v1/badge)](http://gowalker.org/github.com/Unknwon/goconfig)
========
[中文文档](README_ZH.md)
**IMPORTANT**
- This library is under bug fix only mode, which means no more features will be added.
- I'm continuing working on better Go code with a different library: [ini](https://github.com/go-ini/ini).
## About
Package goconfig is a easy-use, comments-support configuration file parser for the Go Programming Language, which provides a structure similar to what you would find on Microsoft Windows INI files.
The configuration file consists of sections, led by a `[section]` header and followed by `name:value` or `name=value` entries. Note that leading whitespace is removed from values. The optional values can contain format strings which refer to other values in the same section, or values in a special DEFAULT section. Comments are indicated by ";" or "#"; comments may begin anywhere on a single line.
## Features
- It simplified operation processes, easy to use and undersatnd; therefore, there are less chances to have errors.
- It uses exactly the same way to access a configuration file as you use Windows APIs, so you don't need to change your code style.
- It supports read recursion sections.
- It supports auto increment of key.
- It supports **READ** and **WRITE** configuration file with comments each section or key which all the other parsers don't support!!!!!!!
- It supports get value through type bool, float64, int, int64 and string, methods that start with "Must" means ignore errors and get zero-value if error occurs, or you can specify a default value.
- It's able to load multiple files to overwrite key values.
## Installation
go get github.com/unknwon/goconfig
## API Documentation
[Go Walker](http://gowalker.org/github.com/unknwon/goconfig).
## Example
Please see [conf.ini](testdata/conf.ini) as an example.
### Usage
- Function `LoadConfigFile` load file(s) depends on your situation, and return a variable with type `ConfigFile`.
- `GetValue` gives basic functionality of getting a value of given section and key.
- Methods like `Bool`, `Int`, `Int64` return corresponding type of values.
- Methods start with `Must` return corresponding type of values and returns zero-value of given type if something goes wrong.
- `SetValue` sets value to given section and key, and inserts somewhere if it does not exist.
- `DeleteKey` deletes by given section and key.
- Finally, `SaveConfigFile` saves your configuration to local file system.
- Use method `Reload` in case someone else modified your file(s).
- Methods contains `Comment` help you manipulate comments.
- `LoadFromReader` allows loading data without an intermediate file.
- `SaveConfigData` added, which writes configuration to an arbitrary writer.
- `ReloadData` allows to reload data from memory.
Note that you cannot mix in-memory configuration with on-disk configuration.

- All characters are CASE SENSITIVE, BE CAREFUL!
