How to make contributions to goSam

<p>
Welcome to goSam, the easy-to-use http client for i2p. We&rsquo;re glad you&rsquo;re here
and interested in contributing. Here&rsquo;s some help getting started.

<h3>
(1) Environment
</h3>
<p>
goSam is a simple go library. You are free to use an IDE if you wish, but all
that is required to build and test the library are a go compiler and the gofmt
tool. Git is the version control system. All the files in the library are in a
single root directory. Invoking go build from this directory not generate any
files.
</p>
<h3>
(2) Testing
</h3>
<p>
Tests are implemented using the standard go &ldquo;testing&rdquo; library in files named
&ldquo;file_test.go,&rdquo; so tests of the client go in client_test.go, name lookups
in naming_test.go, et cetera. Everything that can be tested, should be tested.
</p>
<p>
Testing is done by running
</p>
<pre><code> go test
</code></pre>
<p>
More information about designing tests is below in the
<strong>
Contributing Code/Style Guide
</strong>
section below.
</p>
<h3>
(3) Filing issues/Reporting bugs/Making suggestions
</h3>
<p>
If you discover the library doing something you don&rsquo;t think is right, please let
us know! Just filing an issue here is OK.
</p>
<p>
If you need to suggest a feature, we&rsquo;re happy to hear from you too. Filing an
issue will give us a place to discuss how it&rsquo;s implemented openly and publicly.
</p>
<p>
Please file an issue for your new code contributions in order to provide us with
a place to discuss them for inclusion.
</p>
<h3>
(4) Contributing Code/Style Guide
</h3>
<p>
Welcome new coders. We have good news for you, this library is really easy to
contribute to. The easiest contributions take the form of i2cp and tunnel
options.
</p>
<h4>
(a) Adding i2cp and tunnel Options
</h4>
<p>
First, add a variable to store the state of your new option. For example, the
existing variables are in the Client class
<a href="https://github.com/cryptix/goSam/blob/701d7fcf03ddb354262fe213163dcf6f202a24f1/client.go#L29">
here:
</a>
</p>
<p>
i2cp and tunnel options are added in a highly uniform process of basically three
steps. First, you create a functional argument in the options.go file, in the
form:
</p>
<pre><code class="language-Go"> // SetOPTION sets $OPTION
func SetOPTION(arg type) func(*Client) error { // arg type
return func(c *Client) error { // pass a client to the inner function and declare error return function
if arg == valid { // validate the argument
c.option = s // set the variable to the argument value
return nil // if option is set successfully return nil error
}
return fmt.Errorf(&quot;Invalid argument:&quot; arg) // return a descriptive error if arg is invalid
}
}
</code></pre>
<p>
<a href="https://github.com/cryptix/goSam/blob/701d7fcf03ddb354262fe213163dcf6f202a24f1/options.go#L187">
example
</a>
</p>
<p>
Next, you create a getter which prepares the option. Regardless of the type of
option that is set, these must return strings representing valid i2cp options.
</p>
<pre><code class="language-Go"> //return the OPTION as a string.
func (c *Client) option() string {
return fmt.Sprintf(&quot;i2cp.option=%d&quot;, c.option)
}
</code></pre>
<p>
<a href="https://github.com/cryptix/goSam/blob/701d7fcf03ddb354262fe213163dcf6f202a24f1/options.go#L299">
example
</a>
</p>
<p>
Lastly, you&rsquo;ll need to add it to the allOptions function and the
Client.NewClient() function. To add it to allOptions, it looks like this:
</p>
<pre><code class="language-Go"> //return all options as string ready for passing to sendcmd
func (c *Client) allOptions() string {
return c.inlength() + &quot; &quot; +
c.outlength() + &quot; &quot; +
... //other options removed from example for brevity
c.option()
}
</code></pre>
<pre><code class="language-Go"> //return all options as string ready for passing to sendcmd
func (c *Client) NewClient() (*Client, error) {
return NewClientFromOptions(
SetHost(c.host),
SetPort(c.port),
... //other options removed from example for brevity
SetCompression(c.compression),
setlastaddr(c.lastaddr),
setid(c.id),
)
}
</code></pre>
<p>
<a href="https://github.com/cryptix/goSam/blob/701d7fcf03ddb354262fe213163dcf6f202a24f1/options.go#L333">
example
</a>
</p>
<h4>
(b) Writing Tests
</h4>
<p>
Before the feature can be added, you&rsquo;ll need to add a test for it to
options_test.go. To do this, just add your new option to the long TestOptions
functions in options_test.go.
</p>
<pre><code class="language-Go"> func TestOptionHost(t *testing.T) {
client, err := NewClientFromOptions(
SetHost(&quot;127.0.0.1&quot;),
SetPort(&quot;7656&quot;),
... //other options removed from example for brevity
SetCloseIdleTime(300001),
)
if err != nil {
t.Fatalf(&quot;NewClientFromOptions() Error: %q\n&quot;, err)
}
if result, err := client.validCreate(); err != nil {
t.Fatalf(err.Error())
} else {
t.Log(result)
}
client.CreateStreamSession(&quot;&quot;)
if err := client.Close(); err != nil {
t.Fatalf(&quot;client.Close() Error: %q\n&quot;, err)
}
}
func TestOptionPortInt(t *testing.T) {
client, err := NewClientFromOptions(
SetHost(&quot;127.0.0.1&quot;),
SetPortInt(7656),
... //other options removed from example for brevity
SetUnpublished(true),
)
if err != nil {
t.Fatalf(&quot;NewClientFromOptions() Error: %q\n&quot;, err)
}
if result, err := client.validCreate(); err != nil {
t.Fatalf(err.Error())
} else {
t.Log(result)
}
client.CreateStreamSession(&quot;&quot;)
if err := client.Close(); err != nil {
t.Fatalf(&quot;client.Close() Error: %q\n&quot;, err)
}
}
</code></pre>
<p>
If any of these tasks fail, then the test should fail.
</p>
<h4>
&copy; Style
</h4>
<p>
It&rsquo;s pretty simple to make sure the code style is right, just run gofmt over it
to adjust the indentation, and golint over it to ensure that your comments are
of the correct form for the documentation generator.
</p>
<h4>
(d) Other kinds of modification?
</h4>
<p>
It may be useful to extend goSam in other ways. Since there&rsquo;s not a
one-size-fits-all uniform way of dealing with these kinds of changes, open an
issue for discussion and
</p>
<h3>
(5) Conduct
</h3>
<p>
This is a small-ish, straightforward library intended to enable a clear
technical task. We should be able to be civil with eachother, and give and
accept criticism contructively and respectfully.

has support for all streaming features SAM version 3.2.
STATUS: This project is maintained. I will respond to issues, pull requests, and feature requests within a few days. I am primarily maintaining functionality. This is widely used and easy to use, but thusfar, mostly by me. It sees a lot of testing and no breaking changes to the API are expected.
This is in an **early development stage**. I would love to hear about any

### Using SAM by default, as a proxy for all HTTP Clients used by a Go application
This will make the SAM transport dialer the default for all HTTP clients.

## Using it as a SOCKS proxy
`client` also implements a resolver compatible with
[`getlantern/go-socks5`](https://github.com/getlantern/go-socks5),
making it very easy to implement a SOCKS5 server.

.deb package
</h3>
<p>
A package for installing this on Debian is buildable, and a version for Ubuntu
is available as a PPA and mirrored via i2p. To build the deb package, from the
root of this repository with the build dependencies installed(git, i2p, go,
debuild) run the command
</p>
<pre><code> debuild -us -uc
</code></pre>
<p>
to produce an unsigned deb for personal use only. For packagers,
</p>
<pre><code> debuild -S
</code></pre>
<p>
will produce a viable source package for use with Launchpad PPA&rsquo;s and other
similar systems.
