You probably want `$TRAVIS_BUILD_DIR`, which is the directory we clone the repository to and `cd` into afterwards, before running your tests.

I would like to create a confidence band for a model fitted with gls like this:

    require(ggplot2)
    require(nlme)

    mp &lt;-data.frame(year=c(1990:2010))

    mp$wav &lt;- rnorm(nrow(mp))*cos(2*pi*mp$year)+2*sin(rnorm(nrow(mp)*pi*mp$wav))+5
    mp$wow &lt;- rnorm(nrow(mp))*mp$wav+rnorm(nrow(mp))*mp$wav^3

    m01 &lt;- gls(wow~poly(wav,3), data=mp, correlation = corARMA(p=1))

    mp$fit &lt;- as.numeric(fitted(m01))

    p &lt;- ggplot(mp, aes(year, wow))+ geom_point()+ geom_line(aes(year,fit))
    p

This only plots the fitted values and the data, and I would like something in the style of


    p &lt;- ggplot(mp, aes(year, wow))+ geom_point()+ geom_smooth()
    p

but with the bands generated by the gls model.

Thanks!

I am building an [`OAuth 1.0(a)`][1] authorization server using [`DotNetOpenAuth`][2] (NuGet package `DotNetOpenAuth.OAuth.ServiceProvider, version = 4.1.4.12333`). The server is hosted in an ASP.NET application but that&#39;s irrelevant to the question.

My [`ServiceProvider`][3] is configured like this:

    private ServiceProvider GetServiceProvider()
    {
        var baseUri = &quot;http://myauth.com&quot;;
        return new ServiceProvider(
            new ServiceProviderDescription
            {
                UserAuthorizationEndpoint = new MessageReceivingEndpoint(
                    new Uri(baseUri + &quot;/get_request_token&quot;), 
                    HttpDeliveryMethods.GetRequest
                ),
                RequestTokenEndpoint = new MessageReceivingEndpoint(
                    new Uri(baseUri + &quot;/authorize&quot;), 
                    HttpDeliveryMethods.PostRequest
                ),
                AccessTokenEndpoint = new MessageReceivingEndpoint(
                    new Uri(baseUri + &quot;/get_token&quot;), 
                    HttpDeliveryMethods.PostRequest
                ),
                ProtocolVersion = ProtocolVersion.V10a,
                TamperProtectionElements = new ITamperProtectionChannelBindingElement[] 
                {
                    new PlaintextSigningBindingElement(),
                    new HmacSha1SigningBindingElement(),
                },
            },
            tokenManager,
            new OAuthServiceProviderMessageFactory(tokenManager)
        );
    }

The relevant part of my `get_request_token` endpoint looks like this:

    var serviceProvider = GetServiceProvider();
    var tokenRequest = serviceProvider.ReadTokenRequest();

Now when a consumer sends the following request to this endpoint:

    GET /get_request_token?oauth_nonce=C5657420BCE5F3224914304376B5334696B09B7FFC17C105A7F9629A008869DC&amp;oauth_timestamp=1356006599&amp;oauth_consumer_key=sampleconsumer&amp;oauth_signature_method=plaintext&amp;oauth_signature=samplesecret%26&amp;oauth_version=1.0&amp;oauth_callback=http%3a%2f%2flocalhost%3a30103%2fCustomOAuth1 HTTP/1.1
    
    Host: localhost:8180
    Connection: close

(broken for clarity):

    oauth_nonce=C5657420BCE5F3224914304376B5334696B09B7FFC17C105A7F9629A008869DC
    oauth_timestamp=1356006599
    oauth_consumer_key=sampleconsumer
    oauth_signature_method=plaintext
    oauth_signature=samplesecret%26
    oauth_version=1.0
    oauth_callback=http%3a%2f%2flocalhost%3a30103%2fCustomOAuth1

The `serviceProvider.ReadTokenRequest()` method throws an exception:

    The UnauthorizedTokenRequest message required protections {All} but the channel could only apply {Expiration, ReplayProtection}.
       at DotNetOpenAuth.Messaging.Channel.ProcessIncomingMessage(IProtocolMessage message)
       at DotNetOpenAuth.Messaging.Channel.ReadFromRequest(HttpRequestBase httpRequest)
       at DotNetOpenAuth.Messaging.Channel.TryReadFromRequest[TRequest](HttpRequestBase httpRequest, TRequest&amp; request)
       at DotNetOpenAuth.OAuth.ServiceProvider.ReadTokenRequest(HttpRequestBase request)
       at DotNetOpenAuth.OAuth.ServiceProvider.ReadTokenRequest()
       at OAuthServers.OAuth1.Services.OAuth1Service.Any(GetRequestTokenRequest request)
       at lambda_method(Closure , Object , Object )
       at ServiceStack.ServiceHost.ServiceRunner`1.Execute(IRequestContext requestContext, Object instance, TRequest request)

On the other hand if the client sends the following request:

    GET /get_request_token?oauth_callback=http%3a%2f%2flocalhost%3a65271%2foauth1%2fHandleAccessToken&amp;oauth_consumer_key=sampleconsumer&amp;oauth_nonce=rGFvxlWm&amp;oauth_signature_method=HMAC-SHA1&amp;oauth_signature=HV%2f5Vq%2b0cF3NrtiISE9k4jmgCrY%3d&amp;oauth_version=1.0&amp;oauth_timestamp=1356007830 HTTP/1.1

    Host: localhost:8180
    Connection: close

(broken for clarity):

    oauth_callback=http%3a%2f%2flocalhost%3a65271%2foauth1%2fHandleAccessToken
    oauth_consumer_key=sampleconsumer
    oauth_nonce=rGFvxlWm
    oauth_signature_method=HMAC-SHA1
    oauth_signature=HV%2f5Vq%2b0cF3NrtiISE9k4jmgCrY%3d
    oauth_version=1.0
    oauth_timestamp=1356007830

it succeeds. 

As you can see the only difference between those 2 requests is the `oauth_signature_method` being used. In the first case `PLAINTEXT` is used whereas in the second `HMAC-SHA1`.

Is it possible to make DotNetOpenAuth accept a `PLAINTEXT` signature method for the request token endpoint along with the GET verb (even if the [`OAuth 1.0(a) specification`][4] recommends POST to be used for this endpoint)? Is there some config option that could *relax* this requirement on the server? 

At the moment modifying the client is not an option for me.

When working with the .travis.yml, is there an environment variable that contains the name of the current build directory in Travis-CI?  Looking through the docs [here][1] I don&#39;t see one.

I have a github repository `user/repo` but the real project is in a subfolder `user/repo/project/build.sbt`  
What should I write in the `.travis.yml` to make Travis ignore the top folder and work only in the project folder?

Inspired by [this](https://stackoverflow.com/questions/14006810/how-do-i-get-travis-build-working-directory-in-travis-yml) I tried the following which didn&#39;t work:

    env:
      global:
        - REPO=&quot;user/repo&quot;
        - CI_HOME=`pwd`/$REPO
    script: sh -c &#39;cd $CI_HOME/project&#39; &amp;&amp; sbt ++$TRAVIS_SCALA_VERSION package

Error log:

    $ sh -c &#39;cd $CI_HOME/project&#39; &amp;&amp; sbt ++$TRAVIS_SCALA_VERSION package
    Detected sbt version 0.12.2-RC1
    /home/travis/build/user/repo doesn&#39;t appear to be an sbt project.

Ideally there should be a way to specify the build folder but let Travis handle the build command.

How to specify a build folder in Travis?

I&#39;m using [Travis-CI][1] to provide continuous integration builds for a few Java open source projects I&#39;m working on.

Normally this works smoothly, but I have a problem when the POM specifies GPG signing, e.g. 

    &lt;plugin&gt;
      &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt;
      &lt;artifactId&gt;maven-gpg-plugin&lt;/artifactId&gt;
      &lt;version&gt;1.4&lt;/version&gt;
      &lt;executions&gt;
        &lt;execution&gt;
          &lt;id&gt;sign-artifacts&lt;/id&gt;
          &lt;phase&gt;verify&lt;/phase&gt;
          &lt;goals&gt;
            &lt;goal&gt;sign&lt;/goal&gt;
          &lt;/goals&gt;
        &lt;/execution&gt;
      &lt;/executions&gt;
    &lt;/plugin&gt;

This causes the Travis build to fail - apparently because it does not have a passphrase available while running `mvn install`. See [this build][2] for an example.

What is the best way to configure Maven and/or Travis to skip GPG signing for CI test builds, but still perform GPG signing when I do a proper release build?

Suppressing GPG signing for Maven-based continuous integration builds (Travis CI)

Using Travis-CI, is it possible to trigger a rebuild without pushing a new commit to GitHub?

Use case: A build fails due to an externality. The source is actually correct. It would build OK and pass if simply re-run.

For instance, an `apt-get` fails due to a package server being down, but the server is back up again. However the build status is &quot;stuck&quot; at &quot;failed&quot; until a new commit is pushed.

Is there some way to nudge Travis-CI to do another build, other than pushing a &quot;dummy&quot; commit?

Trigger a Travis-CI rebuild without pushing a commit?

In my github repo&#39;s `readme.md` file I have a Travis-CI badge. I use the following link:

    https://travis-ci.org/joegattnet/joegattnet_v3.png?branch=staging

The obvious problem is that the branch is hardcoded. Is it possible to use some sort of variable so that the branch is the one currently being viewed?
