Issue: updating Field AllowedValues that differ only by casing

Issue

Say you created a field and by mistake, there was a typo in one of the allowed values:

<FieldDefinition name="FieldToTestLowerUpperCase" refname="Custom.FieldToTestLowerUpperCase" type="String">
   <ALLOWEDVALUES expanditems="true">
     <LISTITEM value="Out of scope" />
     <LISTITEM value="Value 1" />
     <LISTITEM value="Value 2" />
   </ALLOWEDVALUES>
</FieldDefinition>

What you really wanted was “Out of Scope”, not “Out of scope”:

<FieldDefinition name="FieldToTestLowerUpperCase" refname="Custom.FieldToTestLowerUpperCase" type="String">
   <ALLOWEDVALUES expanditems="true">
     <LISTITEM value="Out of Scope" />
     <LISTITEM value="Value 1" />
     <LISTITEM value="Value 2" />
   </ALLOWEDVALUES>
</FieldDefinition>

Using Process Editor, even if you modify and republish the value, it does not change the casing.

Troubleshooting

I have been able to replicate your scenario with Process Tools Editor within VS 2013 Update 3 and TFS 12.0.30723.0 (Tfs2013.Update3).

I deleted the field using Process Editor to take it out of a custom Task, and then deleted it in the command line with witadmin:

witadmin deletefield

/collection:http://<tfsserver>:8080/tfs/<yourcollection> /n:Custom.FieldToTestLowerUpperCase

then re-added it using Process Editor with the right case (“Out of Scope”) and told it to rebuild the cache (“witadmin rebuildcache”). It still did not work, it still kept the same value.

I applied a simple change (add an extra space between “of” and “Scope”, saved it) and the new one had the uppercase plus the extra space (“Out of  Scope”). Then I modified the new field to use just a single space, rebuilt the cached, but it returned to using lowercase (“Out of scope”).

To see whether it was a bug with Process Editor, I did all operations using just witadmin in a command line prompt. It still did not work: even after an update, I would retrieve the work item definition and it would show the word “scope” in lowercase.

This value was cached somewhere, and not being able to update it is definitely a bug. By looking into the Fields table I confirmed that nothing really is deleted, only marked as deleted, and most likely it is reused when the value is reinserted. In addition, when a field AllowedValues is changed, the Import method (either using Process Editor, witadmin or the API) does not consider casing when checking whether the value needs to be updated.

Workaround

I found the “Out of scope” value in the TFS Constants table (within the collection database):

SELECT

PartitionId, ConstID, DomainPart, fInTrustedDomain, NamePart, DisplayPart, String, ChangerID, AddedDate, RemovedDate, SID, Cachestamp, ProjectID, TeamFoundationId, fReferenced

FROM Constants

WHERE (DisplayPart = 'Out of scope')

ORDER BY DisplayPart

Next I manually updated it to “Out of Scope”, and refreshed. This fixed the issue.

ATTENTION: Do this at your own risk, as modifying TFS tables directly is neither recommended nor supported, and might put your database in an unsupported state. I tested this on a sample TFS installation, which is not in production.

I only provided this workaround as a last resort and because it was a simple enough update of a string value. A better, supported path would be to open a case with Microsoft support using your MSDN incidents, and have it escalated to the Product Team as a Bug (I might also open a bug with Connect later, and will post the link here).

A few pointers on how to use Delphi applications with Coded UI

To use Delphi-based UIs with Coded UI tests you would need to implement the MSAA interface for each component you would want to use/have it visible with Coded UI.  Example implementations:

-          TEdit:

-          TreeView

The Coded UI extensibility framework works mostly with MSAA compliant applications (http://msdn.microsoft.com/en-us/library/dd380742.aspx). However, if you  can’t get the Delphi source code and enable MSAA, you will have to do with the plain Windows Win32 support (http://msdn.microsoft.com/en-us/library/dd380742.aspx ).

Is it possible to build a plug-in or add-on in .NET using Coded UI extensibility for identifying Delphi (VCL) UI controls native properties (like id, control name)? As mentioned before, it is the UI control itself that has to expose MSAA compliant properties to be visible, that is, the TEdit or TForm needs to implement it. However the documentation on how to used CodedUI with Silverlight states the following:

“To test your Silverlight applications, you must add Microsoft.VisualStudio.TestTools.UITest.Extension.SilverlightUIAutomationHelper.dll as a reference to your Silverlight 4 application so that the Silverlight controls can be identified. This helper assembly instruments your Silverlight application to enable the information about a control to be available to the Silverlight plugin API that you use in your coded UI test or is used for an action recording.

If I understand this correctly, it might be possible to do the same for Delphi CLR .NET applications at the assembly level (I have not seen any reference implementation on how to do this though). For applications compiled to native code you would have to go to the source as explained above.

Issue: Failed to push new glyph for <file-excluded-by-gitignore> Return code from SccGlyphChanged was -2147024809

Issue

Visual Studio 2013 Ultimate Update 3 RTM with Microsoft git provider returns error "Failed to push new glyph for <file-excluded-by-gitignore> Return code from SccGlyphChanged was -2147024809." in Output window.

Details

Issue occurs every time an a file is modified in an editor. The focus switches to the Output window with label "Source Control  - Git". An error message as above is returned for each file excluded by patterns in .gitignore.

Analysis

This an issue with the way that Solution Explorer is interacting with the notifications from the git source control provider.

A glyph is a source control UI element, that is all those little symbols on the left side of the file in Solution Explorer, as explained in implementing a source control provider. This post talks at length about what is going on in a general fashion, including explaining what the error message number means.

What is missing is the connection with .gitignore patterns. This might point to some logic error in the code that handles the background processing that updates the Solution Explorer UI every time a file source control status is modified by editing it in place.

User was using Update 3 RC prior to installing Update 3 RTM, therefore this might be a left over from RC.

I looked into another related issue with .gitignore that when you have a specific exclusion rule (say "/TFS"), it does not process the file (with a name that starts with "TFS"), plus the Solution Explorer glyph changes to that of a committed file. The workaround for this was to take out the .gitignore rules. Another would be to through suppressing the Output window activation and filtering out messages related to this error by using its automation interface.

All points to an issue with the way that the git provider interacts with the Visual Studio UI.

Resolution

I have confirmed with Microsoft that this is a bug and that it has been fixed in an upcoming version.

Dynamically creating or modifying controls in a TFS form

TFS forms can only be modified at design time.

The TFS forms engine is capable of specifying different layouts for different targets, which already tells us that it is a subset of the rendering engines for those targets, and as far as I know, with less capabilities. One of the restrictions is exactly that forms can only be modified at design time.

As a workaround, at the bottom of the page on how to specify work item form controls, there is a link to an article on how to implement a custom control using Winforms. It might be possible to create a custom control with multiple drop down boxes which are dynamically displayed; I have not yet tried that.

You can get better samples on how to implement a custom control in the Custom Controls for TFS Work Item Tracking project at CodePlex. The challenge though will be to also generate a web implementation for the same control, otherwise your work items will be visible only from Team Explorer.

Issue Workaround: When launching a test from MTM, Test Runner does not launch

Issue

When launching a test from MTM, either manual or automated, it would get the message, MTM does not launch Test Runner and fails to do anything. The following error message was added to the Event Log after failure:

    <Provider Name="VSTTExecution" />

    <Data>(mtm.exe, PID 16168, Thread 1) Exception: System.IO.FileNotFoundException

                Message: Could not load file or assembly 'Microsoft.VisualStudio.TestTools.UITest.WindowsStoreUtility, Version=12.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

Troubleshooting

We tried running it from another computer to isolate the Visual Studio Ultimate as the issue. It worked on another computer with Visual Studio Ultimate 2013 Update 3. The failing computer had Visual Studio Ultimate Update 2.

Resolution/Workaround

Root cause was not determined. Installing Update 3 fixed it.

SAFe: one option to scale Agile

The last year has been marked by the steady adoption of SAFe (Scaled Agile Framework) in companies that, although already development powerhouses, still had been struggling to transform themselves into Agile development shops. So SAFe has played an increasingly important role in those companies transitioning from more traditional SDLCs to Agile based ones.

So what is SAFe? It is the evolution of Dean Leffingwell's long time work in methodologies in general, starting with RUP, tempered with his practical experience in bringing Agile and Lean to many companies over the last ten years. According to its website, "The Scaled Agile Framework is an interactive knowledge base for implementing Agile practices at enterprise scale." As such is has a nicely crafted big picture with hundreds of icons you can drill down to and learn more about a specific topic, sometime going even deeper. It reminded me of the richness you get from the RUP documentation, albeit all of it related to current and relevant Agile topics.

image

The navigation is a bit bumpy because in order to protect their IP, the authors made it difficult to see more than one topic at a time (no “open link in new tab option”), and you can’t select text either, so if you are quoting them you will need to type it all. Other than that it can be seen as a rich “map” to all things Agile in an enterprise. The main references of SAFe are Leffingwell's books (both available at Safari):

How is SAFe different from Scrum? The short answer is that it encompasses Scrum. You could say that Scrum targets the team, and that SAFe targets the enterprise. Though based on Lean and Agile principles at the micro, team level, it also addresses architecture, integration, funding, governance and roles at the macro or enterprise level.

And here is what is relevant to a Business Analyst: it clearly provides a way to structure and manage requirements at the enterprise level. It starts by reasserting what has become pretty much the standard best practice in requirements management hierarchy levels, Portfolio, Program and Team:

· Portfolio: Business and Architecture epics, epics span releases

· Program: Features fit releases

· Team: Stories fit in iterations

The novelty of SAFe stems from providing practical solutions to some of the “elephant-in-the-room” problems that have prevented scaling up requirements management in many companies. Among these, three caught my attention:

· Architecture runways: this is something obvious for the technical team, but SAFe makes it explicit by adding Architecture epics as an item in the Portfolio backlog. An Architectural Runway “is the extant technical infrastructure (instantiated in code) necessary to support the implementation of upcoming features without excessive, delay-inducing, redesign.” By having Architecture topics explicit, businesses now become aware of the hidden part of the iceberg needed to implement business features: a plane can’t safely fly without a runaway.

· Agile Release Train: it is “a long-lived team of agile teams, typically consisting of 50-125 individuals, that serves as the program-level value delivery mechanism in SAFe. “ This is the equivalent of a Scrum team but at the program or release level. By having this concept clearly understood, business becomes aware about the need to support using a common team sprint cadence, and “teams are aligned to a common mission via a single Program Backlog”. You could say that this idea is similar to Scrum-of-Scrums concept, but it goes beyond in unifying the teams around the idea of releasing Potentially Shippable Increments (PSIs) as a unit, and not just synchronizing the efforts of separate Scrum teams at the backlog level but still not coordinating the delivery of working software, which is after all the measure of progress for Agile teams.

· Investment Themes: by adding this to a portfolio backlog, and mapping it directly downstream to its ramifications at program and team level, it ensures that what is being worked on has been budgeted, and that execution is tied to strategy. Business becomes aware of the need to prioritize and the repercussions downstream of short-changing initiatives that might affect its financial future.

Reception

SAFe is not without its critics. It has been bashed by both Lean and Agile/Scrum champions such as David Anderson, Ken Schwaber, and Mike Cohn. However it seems that those initial reactions "throw the baby out with the water", to use an old expression. There is definitely value in the framework, but only if considered within an understanding of how ideas are adopted and used within the enterprise.

For the Scrum practitioner, a minor annoyance is its confusing definition of Scrum: Leffingwell invented “SAFe ScrumXP” as a combination of Scrum project management techniques with XP engineering practices. This separation stems from a backwards pseudo-definition of Scrum from 15 years ago, when the perception was of Scrum as being solely a project management framework. At the time Mike Beedle coined the name “Xbreed” (later “Enterprise Agile Process”) to mean exactly Scrum + XP.

“Xbreed” didn’t catch because eventually everyone started to use the word “Scrum” to mean engineering practices as well (notice how Beedle already says that here even for XBreed), and later Scrum.org and ScrumAlliance made it official by adding the “Professional Scrum Developer” and “Certified Scrum Developer” courses focused exactly on teaching engineering practices alongside the Scrum project management framework.

Finally, among the strongest criticisms is that SAFe does not conform to a well-known process adoption best practice popularized by Alistair Cockburn: "stretch to fit". Like RUP, SAFe needs to be tailored in size, and many might be tempted to adopt everything when in doubt about what to do. SAFe can then be used at the Shu and maybe a bit at the Ha levels (as referred by Cockburn), but for experienced Agile practitioners, both in the technical and product management sides of the business, SAFe will appear overwhelming and verbose, and might get in the way as feeling over prescriptive. However, for companies coming out traditional SDLC middle ages, SAFe can feel like the map of a gold mine. It gives to the uninitiated in the Agile wisdom a sense of direction and security to finally start experimenting on how to get out of the Waterfall corner many businesses brought themselves to.

Example on how to handle IT support communications

Microsoft's VSO support blog provides a nice example on how to handle IT support communications:

Notice how redundancy is accounted for: if for any reason the Microsoft web properties are down, the Visual Studio team will continue to update users through Twitter.

Updated information for fixing issue with max number of items in task board

Issue:

=====

When using a TFS 2013 task backlog with more than 500 items, the following message is displayed:

You have exceeded the number of items allowed on your task board. The number of items to be displayed on the task board is: 578. This exceeds the allowed maximum of: 500. This maximum limit is configurable.

To resolve this issue, you can perform one of the following tasks:

·        Reduce the number of items included in the current sprint.

·        Your project administrator must increase the maximum number of allowed items.

You follow the second link, and you are taken to the following page which has outdated information:

http://msdn.microsoft.com/en-us/library/hh739066(VS.110).aspx#count

 

Resolution:

===========

Refer to the updated information  for TFS 2013:

A workaround for issue "TF201072: A user or group could not be found"

Issue:

=====

Although a user is already part of a TFS group, he can't access TFS work items (source code is fine), and TFS Web client/Visual Studio display the following message:  

TF201072: A user or group could not be found. Verify that the users and groups used in your work item type defiition have been added to Team foundation server.

 

Workaround:

=========

The cause is related to some snag in the TFS identity synch service, and it is usually related to a specific collection. There are many articles on the web which help determine the root cause, so here we are only focusing on a fast workaround.

Attaching and re-attaching the collection will force a refresh of the identity synch data, and will usually resolve the issue.
