  • Assembly Version, File Version and Product Version: The Butterfly Effect

    Assembly Version, File Version and Product Version are “related” if you don’t specify them explicitly… and you could be surprised by one of the side effect: loosing you application data or user settings when incrementing the Assembly File Version.

    Click to Read More

    How are those versions specified:

    By default, any new Visual Studio Project includes an AssemblyInfo file defining default values (major, minor, build and revision) for the Assembly Version and Assembly File Version:

    [csharp][assembly: AssemblyVersion("1.0.0.0")]
    [assembly: AssemblyFileVersion("1.0.0.0")][/csharp]
    • A difference in the build number represents a recompilation of the same source. This is usually appropriate because of processor, platform, or compiler changes.
    • Assemblies with the same name, major, and minor version numbers but different revision numbers are intended to be fully interchangeable. This is usually appropriate for security fix, etc …
    • “[assembly: AssemblyVersion(“65534.65534.65534.65534“)]” is maximum.

    MSBuild can auto-increment the build and revision numbers at each build if we provide a (*) in place of those figures. Ex.

    [csharp][assembly: AssemblyVersion("1.0.*")][/csharp]

    or

    [csharp][assembly: AssemblyVersion("1.0.0.*")][/csharp]

    In such cases, the build number is generated based on the current day and the revision number is generated based on the number of seconds since midnight. Replacing the revision number only with a (*) would be irrelevant. Indeed, consecutive builds would most probably have lower revisions.

    There is no default value set for the Product Version when creating a new Visual Studio Project. But a value can be set manually in the AssemblyInfo file using:

    [csharp][assembly: AssemblyInformationalVersion("1.0.0.0")][/csharp]

    Usually, the Product Version is a value like major.minor.build, but it can actually be any string, like “1.0 RC”, etc… Don’t use (*) in this string as it wouldn’t be replaced by an auto-incremented figure. Instead, it would crash your application in some cases (See further for the explanation). Notice also that before VS 2010, using anything else that major.minor.build.rev was resulting in  false warning during compilation.

    What do those versions mean:

    Assembly Version : This is the version number used by framework during build and at runtime to locate, link and load the assemblies. When you add reference to any assembly in your project, it is this version number which gets embedded. At runtime, CLR looks for assembly with this version number to load. But remember this version is used along with name, public key token and culture information only if the assemblies are strong-named signed. If assemblies are not strong-named signed, only file names are used for loading.
     
    Assembly File Version : This is the version number given to file as in file system. It is displayed by Windows Explorer. Its never used by .NET framework or runtime for referencing. But it can be used by OS tools.

    Product Version (a.k.a Assembly Informational Version): Defines an additional version information for an assembly manifest. This is the version you would use when talking to customers or for display on your website..

    What if a version is not specified:

    • If the Assembly version is not explicitly specified, it takes the value of 0.0.0.0.
    • If the Assembly File version is not explicitly specified, it takes the value of the Assembly version.
    • If the Product version is not explicitly specified, it takes the value of the Assembly File version.
    How could issues occurred due to this relation:

    By your fault 🙂

    At work, we recently decided to manage the major and minor numbers of the Assembly Versions at build time, within our TFS Build Process Template. Assembly Versions’ build and release numbers are kept equal to 0 while major and minor are enforced with values provided through Build Definitions’ parameters. At the same time,  we auto-increment the build and release numbers of the Assembly File Versions while keeping their major and minor numbers aligned with those of the Assembly Versions. We don’t touch the Product Version. This was designed as recommended in KB 556041.

    As mentioned, major and minor numbers are specified through custom parameters of our Build Definitions. The build number is computed to reflect directly the current day using a format like “YMMdd” with Y = year modulo x to be <= 6 (None of our product has a longer life). The release number is set with the auto-incremented value provided out-of-the box by Team Build.

    Previously, most of the binaries were compiled locally, on development workstations, and there was no version management at all (There was simply no need for any such versioning): Assembly Version and Assembly File Version were always kept unchanged.

    The change introduced with our Build Process Template had an unexpected consequence: As there never was any Product Version specified explicitly in the AssemblyInfo, binaries’ Product Versions were always equal to the Assembly File Version… kept therefore unchanged through all builds. However, since we started to auto-increment the Assembly File Version, the Product Version started to increment too…

    And ? And some users started to complain that their custom settings were lost after the installation of each new version…

    We quickly noticed that, as usually recommended, developers were making use the two following properties to store  respectively application’s data and users’ data:

    [csharp]Application.CommonAppDataPath[/csharp]
    [csharp]Application.LocalUserAppDataPath[/csharp]

    And after some investigations on MSDN, it appeared that the path returned by those properties depend among other on the Product Version 🙁

    Depending on the OS, CommonAppDataPath is usually like:

    • %SystemDrive%\Documents and Settings\All Users\Application Data\<CompanyName>\<ProductName>\<ProductVersion> or
    • %SystemDrive%\ProgramData\<CompanyName>\<ProductName>\<ProductVersion>

    And LocalUserAppDataPath is like:

    • “%SystemDrive%\Documents and Settings\<UserId>\Local Settings\Application Data\<CompanyName>\<ProductName>\<ProductVersion>” or
    • “%SystemDrive%\Users\<UserId>\AppData\Local\<CompanyName>\<ProductName>\<ProductVersion>“.

    So, indeed, each new release of our product having now a new Product Version, application’s data and users’ data of the previous versions are not used anymore…

    Any (*) used in the Product Version (e.g.: 1.0.*) wouldn’t be replaced by auto-incremented build/release numbers (as mentioned previously), the “AppDataPath”  above would contain an illegal character; reason why the application would crash when accessing this path.

    This also impacted applications accessing settings in the registry with methods like:

    [csharp]Application.UserAppDataRegistry.SetValue()[/csharp]
    [csharp]Application.CommonAppDataRegistry.SetValue()[/csharp]

    Those methods access respectively data under 

    • HKCU\Software\<CompanyName>\<ProductName>\<ProductVersion>\
    • HKLM\Software\<CompanyName>\<ProductName>\<ProductVersion>\

  • From WordPress 3.3 to 3.4 on Synology: Almost YAUN !!

    No! I don’t mean “Yet Another Unix Nerd”!!!

    But upgrading WordPress from 3.3 to 3.4 on my DS209+ was almost “Yet Another Upgrade Nightmare” 🙂

    Click to Read More

    Upgrading a package for Synology is usually really a piece of cake. Unfortunately, the upgrade package for WordPress caused me difficulties.

    First issue: MySQL password

    The setup failed quite immediately after downloading, complaining that there was possibly an issue with the MySQL password. After some investigation, it appeared to me that :

    • the DSM Package Center is running as Synology’s “root” user and
    • the setup of WordPress was trying to access MySql with that account but without any password.
    I found on Synology’s Forum that “Current wordpress package requires an default mysql account root with empty password to create database successfully. If you have set mysql root password before, please install phpMyAdmin to reset the password first.

    And unfortunately (although quite normal), I did set a password for the MySql “root” user in the past… So, as suggested in the message above, I did reset MySql root password to blank.

    • Go to phpMyAdmin, opened the “Users” tab and clicked “Edit Privileges” for the user “root” with Host=localhost.
    • In the “Edit Privileges” dialog box, scroll down to the “Change Password” area and select “No Password” before clicking “Go”.
    • Finally, back to the “Users” page, click “Create PHP code” to apply the change. At that moment, phpMyAdmin could prompt you to re-enter your credentials (root with a blank password).

    I did next restart the update of the WordPress which finally completed fine. But…

    Next issue: Page Not Found

    My Blog was not reachable anymore after the upgrade ? Damned… WordPress was imply disabled… I had to click “Start” next to the WordPress Package in the DSM Package Center 😆

    And finally, my home page appeared… I went immediately to the administration dashboard where I discovered that the setup was actually not yet complete. In this dashboard, I found a message asking me to click a button to upgrade the database. Fortunately, nothing wrong occurred during this upgrade 🙂

    Last issue: This is somewhat embarrassing, isn’t it?

    Although the home page appeared correctly, I was not able to open anything else: no post, no “custom” pages, no categories, … For each of them, I got the WordPress’ “Page Not Found”… All the permalinks appeared somewhat “corrupted”… No idea why.

    Fortunately (bis ter et repetita), fixing this issue was not difficult. I simply had to re-enforce the right Permalinks structure.

    • Go back to the administration dashboard and select the menu “Permalinks” under “Settings”.
    • Check that “your” structure of Permalinks is still selected and did click “Save Changes” (Even if you didn’t change the structure).

    And miracle! Everything went back to normal. I didn’t lose any customization or plugins except my custom smilies from \web\wordpress\wp-includes\images\smilies (fortunately backuped),…

    YASU!!

    No! I Don’t mean “Yet Another System Utility”!!! But “Yet Another Successful Update” 😆

  • Windows Shortcuts and Hot Keys

    A impressive reference guide of shorcuts and hot keys is available on the “Shortcut World” website here, covering various OS (Windows, MacOS, Linux) and products (Autocad, Office, … ). Use the search box to find shortcuts for your software (e.g.: “Windows 7”).

    But the most complete, up-to-date and official, lists of shortcuts for Windows should be the ones provided by Microsoft itself.

    Click to Read More

    Have a look:

    • here for Windows 7, 8.1 and 10
    • here for Windows XP

    To find shortcuts for other Microsoft products (Excel, Word, …) go to the page Accessibility in Microsoft Products, select a product in the list to open the related page and search for the “shortcut” word on that page. you will most probably find what you need 😉

    Notice that you may also create your own “keyboard shortcut” to open a program:

    1. Locate a shortcut to that program (e.g.: via the menu Start > All Programs).
    2. Right-click the shortcut, and then click Properties.
    3. In the Shortcut Properties dialog box, click the Shortcut tab.
    4. In the Shortcut key box, enter the key that you want to use in combination with Ctrl+Alt (keyboard shortcuts automatically start with Ctrl+Alt) and click OK.

    If the same key combination as the shortcut you just created is used by a program currently running, then your shortcut might not work.

  • Drop Builds’ primary output in a “Latest” folder

    As briefly mentioned in another post, we have a specific “Reference Assemblies” folder on the Build Machines containing the latest version of each assembly issued from a successful Build. Assemblies in that folder, know as the “Latest” folder, can be used for “Continuous Integration” Builds.  This post is about the pragmatic solution implemented to drop only the primary output of the Builds in that folder.

    Click to Read More

    The output of a Build contains not only the assemblies and satellite assemblies issued from the compilation of the Visual Studio Projects (I.e.: assemblies part of the “primary output” as named in the Microsoft Setup Projects). It contains also a copy of all the referenced assemblies (file references) with the property “CopyLocal”=”True”.

    It’s important for our purpose to only drop the primary output into the “Latest” folder, otherwise we could override the latest version of some referenced assemblies with a  copy of the specific version found for the Build (e.g.: when targeting the Integration Environment, we use the promoted version on, the assemblies which are possibly not the latest).

    We may not set “CopyLocal”=”False” on all the “file references” because MSTest needs a copy of those in the bin folder to be able to run the unit Tests (That would not be the case if we could find for MSTest an equivalent of the “ReferencePath” parameter of MSBuild).

    We don’t have access to methods (or well described “algorithms”) to retrieve the exact list of assemblies part of the “primary output”. Such methods are only implemented in the Microsoft Setup Projects (Projects not supported, by the way, by MSBuild).

    We don’t want all our developers to add MSBuild Scripts in their Visual Studio Projects to drop the “Targets” in the “Latest” folder.

    Ex. copy “$(TargetDir)$(TargetName).???” “C:\RefAssemblies\Latest”

    This is not only too error prone (like everything you request to a human developer), but it’s also not robust enough. It’s in our opinion impossible to maintain this with enough guarantee taking into account that developers can for example add support for new languages at any time. For each Project, in addition to the assembly $(TargetDir)$(TargetName).dll, we also have to drop the satellite assemblies (e.g.: <culture>\<assemblyname>.resources.dll”), etc…

    The most generic solution we found to identify the assemblies part of the primary output, although quick and dirty, consists in parsing the FileListAbsolute.txt file generated by MSBuild itself and available in the “obj” folder. We “rely” so on direct output of Microsoft (the content of that file) and avoid to implement (and maintain) our own generic (and most probably complex) algorithm (“complex” because I have no idea how to detect satellite assemblies in a Visual Studio Project).

    Notice: We may only drop the primary output of Builds in the “Latest” folder for “Continuous Integration” Builds or Builds targeting the Integration Environment (both using the latest version of the sources). Builds targeting Qualification, Pre-Production or Production use always a specific version of the sources instead of the latest version. Their purpose is indeed to fix a bug in the assemblies deployed in the targeted environment and build with older sources.

  • Customize TFS 201x – my sources of information

    Team Foundation or Team Build can be customized a lot with e.g. our own Build Process Templates, Build Activities or Plug’ins (like TFS Server-Side Event Handlers since TFS 2010). The biggest issue is usually to locate the required Microsoft assemblies on our PC and find the relevant documentation about the “TFS API’s”.

    Click to Read More

    On my own, I had among other to:

    1. Extend TFS with a plugin to check Policies server-side:.
      • This one enforces our branching strategy,
      • Check quota usage and maximum file size,
      • Restrict the file types that can be stored in TFS (no ISO, VHD, MKV – you can’t imagine what end-users can try to store in source control),
      • Validate project folders hierarchy according to our Design patterns, etc…

      Implementing Policies server-side is minimizing the maintenance efforts (nothing to distribute on all the development workstations), fixes are effective immediately after deployment, Policies are enforced for all clients and nobody can bypass them, …

    2. Create customize Build Process Templates to
      • Build Microsoft Setup Projects and Biztalk Projects,
      • Support automatic build deployment,
      • Support online Server maintenance and graceful TFS reboot (waiting on current build to complete before updating or rebooting the server),
      • Validate Build Definitions against our Policies (Build Timeouts, Drop folders location, etc…).

      For any task to be run on Build Servers, we use Custom Build Activities and Custom Build Process Templates, so those tasks can be easily integrated within the Build Schedule, …

    3. And finally, create Visual Studio Plugins to automate some TFS operations, e.g.:
      • Right click a Build to retrieve all its binaries and their sources in order to pass them to our in-house SCRM tool (a.o.: for backward compatibility between TFS and our Release Distribution processes),
      • Right click a Build to automatically create an Maintenance Branch from its sources in order to implement some fixes, …

    I used to be quite comfortable with the customization of Team Build 2005 and 2008, using custom complex MSBuild Scripts. But I didn’t find it easy to start the customization of Build Process Templates using the online MSDN documentation available for Team Build 2010 (i.e.: actually nothing relevant). I did also initially find difficult to implement the same features server side and client side as equivalent TFS API’s are implemented in distinct Microsoft Assemblies and have distinct signatures…

    Fortunately, there are always pioneers who are digging new stuff and publishing their findings on the web. So nowadays we can find a lot of information although the MSDN online documentation is still really poor. Here are my three main sources of information:

    And so far, it seems to me that the changes between TFS 2010 and TFS 2012 are much smaller than between TFS 2008 and TFS 2010. Knowledge only needs to be extended a bit, and not completely renewed. And again, we can count on great blogs to help.

  • Cannot remove/cancel/delete Print jobs

    I did recently had to restart the “Print Spooler” Service to clear the Print job queue where a job was stuck and refused to abort.

    Click to Read More

    I did download the free software – HP Photo Creations – from HP to print at home calendars, greetings cards, etc… It’s missing some essentials features IMO, like “align” pictures/text/etc… but it’s not that bad.

    I just add one issue while printing one of my creation on my PhotoSmart C6280, which is most probably related neither to that model nor to HP Photo Creations, but to the HP Drivers and/or Windows 7: One of the print job in the queue never started to print…

    When print jobs are currently queued/printing, you should see a printer icon :printer: in the notification area. Click on this one to open the print queue. If you don’t see this icon, you can still open the queue  by clicking the Start button :start:, clicking Control Panel, clicking Hardware and Sound, and then clicking Devices and Printers. There, double-click your Printer to open its status window and access the Print Job Queue.

    In that queue, I found my print job in first position, apparently stuck… So I decided to cancel it (right click the job and select “Cancel”). Its status became something like “Deleting – Error – Printing” but the job never disappeared from the queue. Usually, the printer is displaying an error message (e.g.: no paper or ink any more) and once this error solved, the job disappears. But if you don’t find what’s wrong, the easiest solution consists in clearing the queue (including all the other pending jobs if any):

    1. Click Start-R to run a command and type services.msc to open the Service Administration console.
    2. Find the services “Print Spooler” in the list of services (As a tip: Select the first service and type “Print”. The cursor will move directly to the first matching name in the list)
    3. Right-click this “Print Spooler” service and Select “Restart”
    Et voilà. The Print Job Queue is now empty…

  • Target multiple environments with only one TFS Build Server

    I had customize our Build Process Template to support multiple target environments on a single Build Machine. I.e.: to resolve the “file references” at Build time depending on the environment targeted for the deployment.

    Click to Read More

    At work, we have mainly four distinct environments: Integration, Qualification, Pre-Production and Production. Each application (and its referenced assemblies) are promoted from one environment to the next one via tasks (Release Distribution jobs) scheduled according to a predefined monthly Release Plan…

    TFS Build Machines not only compile the applications to be deployed via the standard Release Distribution, but also the urgent fixes to be deployed directly in Pre-Production without passing through Integration and Qualification environments. It also happens, although really quite seldom, that a Build skips the Integration and goes directly to Qualification.

    It’s also to be noticed that none of our applications (assemblies) are strong named and deployed in the GAC, neither on development workstations nor on servers. Instead, all referenced assemblies are always copied within the application’s bin folders, also on the servers.

    Therefore, basically, we would need Build Machines dedicated for each target environment with the adequate assemblies made available on them, for reference resolution purpose. That would be a pity to have such Build Machines (and the related setup, maintenance, backup costs, …) for at most one build per month (Fix in Production and Qualification are fortunately not common).

    To avoid that,  I did customize our Build Process Template to take a Reference Path as input and to pass it to MSBuild. Actually, when editing a Build Definition, the Builder can select the target Environment, and the Build will simply receive a path to the location containing the related assemblies.

    Ex.: MSBuild mySolution.sln /p:ReferencePath=”c:\RefAssemblies\Qualification\”

    How can I be sure that this Reference Path won’t interfere with any Hint Paths defined in the Visual Studio projects?

    First, note that the location provided to MSBuild via the “ReferencePath” parameter will be probed to resolve all “file references” before any other location on the standard probing path. But we also pay attention to not make the assemblies available on the Hint Path on the Build Machines:

    • On Development Workstations, all our assemblies are made available in a single “Reference Assemblies” folder. Developers add references on assemblies in there for development and local testing purpose. They can also start a task at will to update this “Reference Assemblies” folder with the latest version of the assemblies (the versions used in the Integration Environment) or with the version currently deployed in the Qualification or Production Environments (e.g.: for bug fixing purpose).
    • On the Build Machines, there is one “Reference Assemblies” folder per environment (i.e.: updated by the Release Distribution with the assemblies currently in use in that environment). None of those folders is located at the same path as the “Reference Assemblies” folder of the Development Workstations. As a result, MSBuild cannot use the Hint Paths found in the Visual Studio projects to locate the referenced assemblies. Instead, it uses the path of the “Reference Assemblies” folder passed to it via its parameter /p:ReferencePath.

    In addition to the “Reference Assemblies” folders per environment, we also have one  extra folder containing the output of each latest successful Build. This one is used for “Continuous Integration“. No need to update the references in the Visual Studio Projects, MSBuild always find in that folder the latest version of each assembly recently built on any Build Machine (if requested to do so via the Build Definition). This is by the way the default “target environment” for all “Rolling Builds” defined on “Development Branches”, so any breaking features in a new version of a referenced assembly is immediately detected. Builds “candidate” to be promoted use by default the Reference Path with the assemblies from the Integration environment.

  • .Net: Do not Split your Strings

    It could result in an “Out of Memory Exception” on really large strings as a colleague experienced last week.

    Click to Read More

    I admit I used to call Split a lot too as it’s really easy and spares me a bunch of code. Ex.: to parse lines of a CSV file. And yet, the documentation on MSDN is clear about Split performances:

    The Split methods allocate memory for the returned array object and a String object for each array element. If your application requires optimal performance or if managing memory allocation is critical in your application, consider using the IndexOf or IndexOfAny method, and optionally the Compare method, to locate a substring within a string.

    Here is a guy who deeply analyzed the memory issue which occurs when splitting a very large string : “Out of Memory Exception

    And if you need to parse the content of a large .csv, here is an efficient custom parser that can be used instead of calling Split on each line: “Fast CSV Reader

  • Line Break versus Paragraph in WordPress

    For a WordPress beginner (at least for me, who used to write html in notepad++), when editing a post, it is irritating that the ‘Enter’ key is not simply adding a line break but starting automatically a new paragraph instead, especially when typing some pieces of code.

    Fortunately, there is a trick to add a line break without starting a new paragraph.

    Click to Read More

    A new paragraph is usually started after a “Hard break” also known as a “Carriage Return”, which is indeed the default when typing “Enter” in a Word Processor. At the opposite, a simple “Line break” also known as “Soft Break” does not start a new paragraph and result in a normal line-spacing.

    Ex.: The white-space between the previous text and this line is due to a “paragraph separator”. But here after, you will see two lines A. and B. separated by a simple line break.

    A. first line of text
    B. second line of text

    Instead of typing “Enter” at the end of the line A., press “Shift-Enter” instead. That wilt result in a “soft break” (line break) instead of a “hard break” (carriage return).

  • Add categories as dropdown menu in WordPress Navigation Bar

    Edit the file header.php of your theme to add such a menu.

    Click to Read More

    On Synology, this file is accessible via the “web” shared folder (See here for details) at:

    \\<YourSynology>\web\wordpress\wp-content\themes\<YourTheme>\header.php

    Find the right location in the code generating the navigation bar and add something like this (using the adequate ‘class’ from you own theme. Here after, I am using TwentyEleven.)

    [html]

    <!– Add a drop dow menu with all the categories –>
    <div style="text-align:center;">
    <ul id="menu" style="padding:0; margin:0;">
    <li class="cat-item">
    <a href="#" title="Filter by categories.">Categories</a>
    <ul class="children">
    <?php wp_list_categories(‘sort_column=name&sort_order=asc&
    style=list&children=true&hierarchical=true&
    title_li=0&exclude=1’); ?>
    </ul>
    </li>
    </ul>
    </div>

    [/html]

    Instead of href=”#” (to stay on the current page when selecting the head of that menu), you could also use:

    [php]href="<?php echo esc_url( home_url( ‘/’ ) ); ?>"[/php]

    The parameter “exclude=1” is used to skip the category “Uncategorized”. You can add other category IDs to be skipped separated with a comma. To determine the ID of a category, go to “Administration Dashboard > Posts > Categories” and move the mouse over the “Edit” link for that category. Look at the URL displayed by the browser for that link; this one includes the category ID as a parameter: “&tag_ID=xxx”
