Cache server

Cant seem to find much information about GVFS cache servers. What exactly are they and how do you set one up?

I have also observed servers behaving differently when it comes to the Cache Server: Default (no --cache-server-url on command line).

VSTS

Everything works just fine (and you get Using cache server: None in the output).

Bitbucket (on-prem)

Cloning this way gives me the following error:

Cannot clone @ <path>: System.ArgumentNullException: Value cannot be null.
Parameter name: source
   at System.Linq.Enumerable.FirstOrDefault[TSource](IEnumerable`1 source, Func`2 predicate)
   at GVFS.Common.Http.CacheServerResolver.TryResolveUrlFromRemote(String cacheServerName, GVFSConfig gvfsConfig, CacheServerInfo& cacheServer, String& error) in C:\Repos\GitHubUpdate\Internal\GVFS\GVFS.Common\Http\CacheServerResolver.cs:line 59
   at GVFS.CommandLine.GVFSVerb.ResolveCacheServerUrlIfNeeded(ITracer tracer, CacheServerInfo cacheServer, CacheServerResolver cacheServerResolver, GVFSConfig gvfsConfig) in C:\Repos\GitHubUpdate\Internal\GVFS\GVFS\CommandLine\GVFSVerb.cs:line 308
   at GVFS.CommandLine.CloneVerb.Execute() in C:\Repos\GitHubUpdate\Internal\GVFS\GVFS\CommandLine\CloneVerb.cs:line 137

Clone works just fine if adding --cache-server-url None to the gvfs clone command.

Re: the second half of the issue, it appears that Bitbutcket is returning a slightly different response to /gvfs/config than VSTS does, and that’s tripping up the cache resolving code. Regardless, GVFS should be more resilient to these differences, and if the service doesn’t advertise any cache servers, Default and None should resolve to the same thing. We’ll get this fixed in a future release.

FYI: @sanoursa Issue fixed on the Bitbucket side of things in version 0.1.1.
