Add older documents to stream - based on filter

I created a MongoDB watcher to create actions based on the created document.
Of course, the watcher does not detect documents that are created while the service itself is not running.
The current code is only detecting newly created documents.
How can I fetch and add older documents to the pipeline based on a field state e.g.: actionDone : true/false.
var pipeline =
new EmptyPipelineDefinition<ChangeStreamDocument<BsonDocument>>()
.Match(x => x.OperationType == ChangeStreamOperationType.Insert);
using (var cursor = collection.Watch(pipeline))
{
foreach (var change in cursor.ToEnumerable())
{
string mongoID = change.FullDocument.GetValue("_id").ToString();
}
}
Is StartAtOperationTime a option? Didnt find any good documentation here.
Update:
StartAtOperationTime was the solution I was looking for. If anybody is having the same problem, here my solution.
Start to lookup the last 10 days.
var options = new ChangeStreamOptions
{
StartAtOperationTime = new BsonTimestamp(DateTime.Now.AddDays(-10).Ticks)
};
var cursor = collection.Watch(pipeline,options)

TFS API Returns only first level folders C#

Im trying to implement a TFS API to fetch all work items. Its establishing the connection without any trouble. But the issue Im facing is its only fetching the fist levels of folders. Actually the fodler I am looking for is inside those folders. Somewhere deep inside 4th level. Here is the code Im trying
string collectionUri = ConfigurationManager.AppSettings["tfsPath"].ToString();//http://myserver:8080/tfs/defaultcollection
string teamProjectName = ConfigurationManager.AppSettings["tfsProject"];//mycompany
VssConnection connection = new VssConnection(new Uri(collectionUri), new VssCredentials());
// Create instance of WorkItemTrackingHttpClient using VssConnection
WorkItemTrackingHttpClient witClient = connection.GetClient<WorkItemTrackingHttpClient>();
List<QueryHierarchyItem> queryHierarchyItems = witClient.GetQueriesAsync(teamProjectName, depth:2).Result;
foreach(QueryHierarchyItem qh in queryHierarchyItems )
{
string s = qh.Name;
}
// Search for 'Special Queries' folder
QueryHierarchyItem myQueriesFolder = queryHierarchyItems.FirstOrDefault(qhi => qhi.Name.Equals("Special Queries"));
Here queryHierarchyItems is always null. I tried using that for loop above and I found its not getting into second levels of folders. So how can I accomplish my requirement or what I did wrong

If you know the path to the query folder use:
var folder = witClient.GetQueryAsync(teamProject, path, depth: 1).Result;
Then you can access the queries in that folder using something like:
var queries = folder.Children.Where(x => !x.IsFolder.GetValueOrDefault());

WSDL generated service reference returning null

Im have some issues with a service reference to an external source (added it using the supplied wsdl in Visual Studio 2015).
The situation is that the request i run seems to reach the server fine. I also seems to get a response of the expected xml format (added TextWriterTraceListener). But the OutType class i get back in the code (in this case the GetBankCertificateOutType) is always null.
The console application ive built to illustrate is very simple, utilizing the public test account. It looks as follows:
static void Main(string[] args)
{
//instantiates client from the service reference
var client = new PkiServicePortTypeClient();
var time = DateTime.UtcNow;
Random r = new Random();
string reqId = r.Next(100, 999).ToString();
var outType = client.GetBankCertificate(*full params on github*);
//This line will throw nullexception since outType is always null
//BUT a valid response is actually received (although returning aa application statusCode that represents error at this stage)
var response = outType.GetBankCertificateResponse;
}
Ive tried to locate the problem but have been unsuccessful sofar. So wanted to see if someone has some good tip on how to debug this or perhaps has a solution.
I built a complete, minimal, console sample project (including the source wsdl) to illustrtate the issue which is located here.

I've downloaded and inspected your solution, and I found this in trace.log
GetBankCertificateRequest at tribute {http://www.w3.org/XML/1998/namespace}id had invalid value '360817' of type '{http://www .w3.org/2001/XML Schema}ID'
After I played with id value of GetBankCertificateRequest I got back the right value (instead of null).
var outType = client.GetBankCertificate(new GetBankCertificateInType {
RequestHeader = new RequestHeaderType {
SenderId = "360817",
CustomerId = "360817",
RequestId = reqId,
Environment = EnvironmentType.test,
EnvironmentSpecified = true,
InterfaceVersion = "1",
Timestamp = time
},
GetBankCertificateRequest = new GetBankCertificateRequest {
BankRootCertificateSerialNo = "1111110002",
//id = "",
RequestId = reqId,
Timestamp = time
}
});
There is no description for this property according to documentation (PKI service description v2.3.pdf) except some xml type annotation (xml:id). The concrete schema description is missing.

TFS: Programmatically check if local Workspace and Repository are in sync

In my deployment tool I want to check programmatically whether there are updates available for the project which should be deployed somewhere.
The tool should not update the workspace on itself, it's just supposed to warn the user that there is a new version available in the TFS repository.
I tried the following prototypic function to no avail:
public static bool AreWorkspaceAndRepositoryInSync()
{
const string tfsUrl = "http://mytfs:8080/tfs/MyCollection";
const string tfsPath = #"$/Main/MyProject";
const string wsPath = #"C:\DEV\MyProject";
var projectCollection = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri(tfsUrl));
var vcs = projectCollection.GetService<VersionControlServer>();
var workspaceItems = vcs.GetItems(wsPath, RecursionType.Full);
var repositoryItems = vcs.GetItems(tfsPath, VersionSpec.Latest, RecursionType.Full);
var wsNewest = workspaceItems.Items.Max(i => i.CheckinDate);
var repoNewest = repositoryItems.Items.Max(i => i.CheckinDate);
if (wsNewest != repoNewest)
return false;
return true;
}
This function always returns true. I suspect that VersionControlServer.GetItems(...) always retrieves the Items from the server, hence my comparision actually compares two identical list.
Is there a way to get the local workspace Items? Or is there any other way to achieve something similar?

I wouldn't recommend trying to compute it yourself. The best way to do this is to run tf get /preview. That will tell you if there is anything to do but not actually update the workspace. Using the client OM, call Get with VersionSpec.Latest and GetOptions.Preview.

How do I get a previous version of a file with libgit2sharp

I'm trying to use libgit2sharp to get a previous version of a file. I would prefer the working directory to remain as is, at the very least restored to previous condition.
My initial approach was to try to stash, checkout path on the file I want, save that to a string variable, then stash pop. Is there a way to stash pop? I can't find it easily. Here's the code I have so far:
using (var repo = new Repository(DirectoryPath, null))
{
var currentCommit = repo.Head.Tip.Sha;
var commit = repo.Commits.Where(c => c.Sha == commitHash).FirstOrDefault();
if (commit == null)
return null;
var sn = "Stash Name";
var now = new DateTimeOffset(DateTime.Now);
var diffCount = repo.Diff.Compare().Count();
if(diffCount > 0)
repo.Stashes.Add(new Signature(sn, "x#y.com", now), options: StashModifiers.Default);
repo.CheckoutPaths(commit.Sha, new List<string>{ path }, CheckoutModifiers.None, null, null);
var fileText = File.ReadAllText(path);
repo.CheckoutPaths(currentCommit, new List<string>{path}, CheckoutModifiers.None, null, null);
if(diffCount > 0)
; // stash Pop?
}
If there's an easier approach than using Stash, that would work great also.

Unfortunately, Stash pop requires merging which isn't available yet in libgit2.

You may achieve such result by opening two instances of the same repository, each of them pointing to different working directories. The Repository constructor accepts a RepositoryOptions parameter which should allow you to do just that.
The following piece of code demonstrates this feature. This creates an additional instance (otherRepo) that you can use to retrieve a different version of the file currently checked out in your main working directory.
string repoPath = "path/to/your/repo";
// Create a temp folder for a second working directory
string tempWorkDir = Path.Combine(Path.GetTempPath(), "tmp_wd");
Directory.CreateDirectory(newWorkdir);
// Also create a new index to not alter the main repository
string tempIndex = Path.Combine(Path.GetTempPath(), "tmp_idx");
var opts = new RepositoryOptions
{
WorkingDirectoryPath = tempWorkDir,
IndexPath = tempIndex
};
using (var mainRepo = new Repository(repoPath))
using (var otherRepo = new Repository(mainRepo.Info.Path, opts))
{
string path = "file.txt";
// Do your stuff with mainrepo
mainRepo.CheckoutPaths("HEAD", new[] { path });
var currentVersion = File.ReadAllText(Path.Combine(mainRepo.Info.WorkingDirectory, path));
// Use otherRepo to temporarily checkout previous versions of files
// Thank to the passed in RepositoryOptions, this checkout will not
// alter the workdir nor the index of the main repository.
otherRepo.CheckoutPaths("HEAD~2", new [] { path });
var olderVersion = File.ReadAllText(Path.Combine(otherRepo.Info.WorkingDirectory, path));
}
You can get a better grasp of this RepositoryOptions type by taking a look at the tests in RepositoryOptionFixture that exercise it.
