ResourceCopyTask appears to fail when authentication requried [message #1746199]

Hi,

I was trying out a custom setup a couple of months back with 1.4.0 and had everything working nicely. Now I'm tasked with presenting what I worked on and have subsequently downloaded the current version to check everything is OK and found that the ResourceCopyTask no longer appears to work when needing authentication.

The eclipse-inst.ini contains:

-Doomph.redirection.mysite=http://git.eclipse.org/c/oomph/org.eclipse.oomph.git/plain/setups/->http://my.svn.repo/svn/path/to/my/setups/

Note: I've tried https:// too.

Then the project.setup file contians:

  <setupTask
      xsi:type="setup:ResourceCopyTask"
      sourceURL="index:/the_file.ext"
      targetURL="configuration:/the_file.ext"/>

Now when I start the Oomph installer I'm prompted for a username/password. This works successfully and I can proceed through the wizard and the setup starts to install as expected.

Then when it gets to the ResourceCopyTask I am prompted for a username/password again, which I thought odd. Indeed, after unsuccessfully retrying 3 times using the correct credentials, the log shows:

Performing Resource Copy index:/the_file.ext --> configuration:/the_file.ext
Cannot copy non-existing http://my.svn.repo/svn/path/to/my/setups/the_file.ext to file:/C:/develop/eclipse/configuration/the_file.ext

If I copy that URL in to a web browser I can successfully view the file.

So:

What am I doing wrong?
Is there a place to download the older version of the setup EXE so I can do more tests?
If not, can the current install be downgraded in some way so I can do more tests?

Thanks
Chris

It should all be going through the ECFURIHandlerImpl so setting the -Doomph.setup.ecf.trace=true will trace to System.out detailed information about how each URI is processed. Perhaps that will help pinpoint the error.

Certainly I expect a given host to need authentication at most once and I've done a lot of work in the last weeks on authentication issues for a customer with very complex authentication issues. Are you using the latest 1.6 build?

I notice though that the copy task specifically uses uriConverter.exists(sourceURI, null) and that no longer just checks if an input stream can be created but rather calls getAttributes which does a HEAD request instead of a GET request so perhaps the new issue is related to poor handling of the HEAD request logic or perhaps poor handling by the server (i.e., perhaps not returning unauthorized but rather not found).

I can try to reproduce this with the customer site that I've been using, but it's EclipseCon Europe this week, so response time is down. Please feel free to open a Bugzilla if you reach the conclusion that something is not quite right in org.eclipse.oomph.setup.internal.core.util.ECFURIHandlerImpl.getRemoteAttributes(URI, Map<?, ?>) and hopefully I'll be able to reproduce that with a site that behaves similarly...

public boolean exists(URI uri, Map<?, ?> options)
{
return !getAttributes(uri, options).isEmpty();
}

Hi Ed,

Thanks for the response. I have found the old install (1.4.0.2444), and worked out how to get that build running in Eclipse (just to note, the new version I'm running is 1.5.0.2683).

However, the problem I now face is that that build does not work either! So perhaps something has changed at our end, but it is odd how one authorization works but then the next does not.

Anyway, whilst I investigate, here are the traces. For 1.4.0.2444 (d2a2856) which did work:

Digging some more, looking at ECFURIHandlerImpl as suggested I noticed the following:

  private Map<String, ?> getRemoteAttributes(URI uri, Map<?, ?> options) {
...
    String username;
    String password;

    String uriString = uri.toString();
    Proxy proxy = ProxySetupHelper.getProxy(uriString);
    if (proxy != null)
    {
      username = proxy.getUsername();
      password = proxy.getPassword();
    }
    else
    {
      username = null;
      password = null;
    }
...
      if (username != null)
      {
        fileBrowser.setConnectContextForAuthentication(ConnectContextFactory.createUsernamePasswordConnectContext(username, password));
      }
      else if (password != null)
      {
        fileBrowser.setConnectContextForAuthentication(ConnectContextFactory.createPasswordConnectContext(password));
      }

It seemed to me that the un/pwd were never set for authorization. Indeed, if I added some test code (I don't really know how the proxy/authorization un/pwd combination is supposed to work, but I'm not behind a proxy):

      else if (authorization != null && authorization.isAuthorized())
      {
        fileBrowser.setConnectContextForAuthentication(
            ConnectContextFactory.createUsernamePasswordConnectContext(authorization.getUser(), authorization.getPassword()));
      }

Then everything started to work, as the trace shows:

I hope all this information is useful. I can open a BugZilla ticket if you like, and I presume you'd want most of this information in it.

Chris,

Looking at the code this morning and seeing this:

// ECF doesn't support such options.
// I'm not sure how it can browser a file that's authorization protected and it also behind an authorization protected firewall.
// Map<Object, Object> requestOptions = new HashMap<Object, Object>();
// requestOptions.put(IRetrieveFileTransferOptions.CONNECT_TIMEOUT, CONNECT_TIMEOUT);
// requestOptions.put(IRetrieveFileTransferOptions.READ_TIMEOUT, READ_TIMEOUT);
// if (authorization != null && authorization.isAuthorized())
// {
// requestOptions.put(IRetrieveFileTransferOptions.REQUEST_HEADERS, Collections.singletonMap("Authorization", authorization.getAuthorization()));
// }

It's clear this cannot work as written for a host that requires authentication. But as the comment suggests, I'm not sure who the combination of a proxy that requires authentication communicating with a host that also requires authentication works. Looking deeper into ECF, I suspect I'm just not doing it quite right. I think probably I should never set the proxy because ECF appears to do this under the covers if I don't set it, and the proxy instance already contains the credentials for communicating with the proxy, so I believe now that the connect context should also be the credentials for the actual host, not the proxy...

Please open a Bugzilla for this problem. I really need to set up some kind of proxy simulator so I can properly test these proxy scenarios; there is already an outstanding bugzilla relating to proxies not working...

Note that as a workaround (maybe) you can ensure that the file is in your cache so that this part of the logic kicks in:

if (!CacheHandling.CACHE_IGNORE.equals(cacheHandling) && uriConverter.exists(cacheURI, options)
&& (!(fileSystemListener.exception instanceof RemoteFileSystemException)
|| ((BrowseFileTransferException)fileSystemListener.exception).getErrorCode() != HttpURLConnection.HTTP_NOT_FOUND))
{
return handleAttributes(requestedAttributes, uriConverter.getAttributes(cacheURI, options));
}
