  • Is Ubuntu a bad distro for a standalone mysql database server?

    - by DhruvPathak
    I read an article here : http://www.mysqlperformanceblog.com/2011/12/08/which-linux-distribution-for-mysql-server/ On the other end there are Debian and Ubuntu. Both use tool called dpkg for package management. There isn’t a month that I log in to a system based on either distribution where there are no issues with packages consistency. Unfinished installations, unresolved conflicts are so common that it’s just beyond simple negligence. The packaging system is just not robust enough. Another problem is that one broken package may block you from installing or uninstalling anything else. Imagine that someone left system in such shape, you prepared for downtime, stopped MySQL and… error – text editor has not been properly installed, so you cannot upgrade MySQL either until the problem is fixed. In a stressful situation when downtime clock ticks – annoying at best We prefer Ubuntu server because of familiarity and Ubuntu also being development environment. Questions: Is Ubuntu used commonly in production for a mysql database server ? Is it worth the trouble ever to have one distro eg Ubuntu in web server, and another say Red Hat in database server ? Or Is a homogenous server pool a better choice ?

  • PHP potential issues with compiling 5.3.8 extensions against RHEL 6 / CentOS 6 PHP 5.3.3 package

    - by user101203
    I'm working on getting a Red Hat 6 LAMP server going and while the PHP that comes with it has many extensions we use, it doesn't have all of them. To solve this, I was thinking about either compiling the PHP extensions which come in the ext folder of the downloadable source code of PHP 5.3.3 from php.net same as #1, but using the extensions from the latest PHP version (currently 5.3.8). Do #1 but manually decide which updates to backport from the latest version of the PHP extensions into the older version and then compile the backported result A drawback to #1 is that security and bug fixes come out which we wouldn't be able to take advantage of. A drawback to #3 is that it might be a lot of work Does anyone know what the drawbacks to #2 are? I don't want to go down that route if it might result in some unexpected negative outcomes. Also, are there any other drawbacks to the other options or a better way to go altogether? I want to use the PHP 5.3.3 which comes with the Linux distro because I don't want us to get to a place again where we are forced to upgrade to a new version of PHP to stay on top of security updates like from PHP 5.2.x to 5.3.x and there be backwards incompatible changes (this is the situation we're in now with PHP 5.2.x no longer being supported).

  • How to make Windows command prompt treat single quote as though it is a double quote?

    - by mark
    My scenario is simple - I am copying script samples from the Mercurial online book (at http://hGBook.red-bean.com) and pasting them in a Windows command prompt. The problem is that the samples in the book use single quoted strings. When a single quoted string is passed on the Windows command prompt, the latter does not recognize that everything between the single quotes belongs to one string. For example, the following command: hg commit -m 'Initial commit' cannot be pasted as is in a command prompt, because the latter treats 'Initial commit' as two strings - 'Initial and commit'. I have to edit the command after paste and it is annoying. Is it possible to instruct the Windows command prompt to treat single quotes similarly to the double one? EDIT Following the reply by JdeBP I have done a little research. Here is the summary: Mercurial entry point looks like so (it is a python program): def run(): "run the command in sys.argv" sys.exit(dispatch(request(sys.argv[1:]))) So, I have created a tiny python program to mimic the command line processing used by mercurial: import sys print sys.argv[1:] Here is the Unix console log: [hg@Quake ~]$ python 1.py "1 2 3" ['1 2 3'] [hg@Quake ~]$ python 1.py '1 2 3' ['1 2 3'] [hg@Quake ~]$ python 1.py 1 2 3 ['1', '2', '3'] [hg@Quake ~]$ And here is the respective Windows console log: C:\Workpython 1.py "1 2 3" ['1 2 3'] C:\Workpython 1.py '1 2 3' ["'1", '2', "3'"] C:\Workpython 1.py 1 2 3 ['1', '2', '3'] C:\Work One can clearly see that Windows does not treat single quotes as double quotes. And this is the essence of my question.

  • Our clients site is redirecting to a pill scammy site [closed]

    - by Alex Demchak
    Possible Duplicate: My server's been hacked EMERGENCY We've usually host our clients site, but we aren't hosting this one. The website itself (weddle-funeral.com) works just fine. if you load google and search for weddle funeral stayton oregon - and click that link, the site links to a scammy pill site. I went through the site and there were some php files in the wordpress plugins that got quarantined by my antivirus. I removed ALL non essential files, and uploaded fresh versions of all the plugins, but it's STILL redirecting from google. I tried logging in to the cpanel (on a virtual private server), and the cpanel flashed a red warning screen The site's security certificate is not trusted! You attempted to reach XXXXX.com, but the server presented a certificate issued by an entity that is not trusted by your computer's operating system. This may mean that the server has generated its own security credentials, which Google Chrome cannot rely on for identity information, or an attacker may be trying to intercept your communications. You should not proceed, especially if you have never seen this warning before for this site. (Keep in mind, that's for the HOSTING accounts CPanel) Is there something in the SERVER probably that's causing the redirect?

  • Problem with Amiga 1200 accelerator board

    - by cc0
    I just recently walked past a dump, where in the corner of my eye I spotted something that looked like a huge keyboard. I went to take a closer look, and found out that it was an Amiga 1200 with a 030 accellerator board and scala dongle. Jackpot! So anyway; I dried it, cleaned it, it works, but the floppy was not powering on and same with the harddrive. I am using an old Amiga 1200 PSU that was making some strange high pitch noise when I tried to boot the amiga with the harddrive installed in it. I removed the harddrive and it booted fine with the PSU not emitting any detectable noise. However, when I have the 030 installed it sometimes reboots and shows a red "Software Error" screen. I tried removing the memory on the board, same effect. Sometimes it does not boot at all, just gives a black screen. Someone suggested the card had problems with 3.1 roms, but this amiga has only 3.0 roms installed. Does anyone have any apparent theories as to why it seems unstable? I don't have any other Amiga parts to cross-swap with to test a lot of things, so I'd really appreciate some sound input here so I'd know what to look for in order to try fix it. And merry Christmas everyone :]

  • Is it possible to theme Windows 7 like XP?

    - by LonelyPixel
    Everybody seems to mean the window frame colour and a set of desktop background pictures when they're talking about Windows 7 themes. Does anybody remember what themes used to be in Windows XP? You could actually alter the appearance of the window frame, how close buttons and menu popups looked, put a texture on the taskbar, all those funny things. Microsoft themselves have published a number of XP themes over time (Luna on XP, Royal on MCE2005, Zune later on). I don't say that most of those and the numerous third party XP themes were beautiful or even practical. But it was possible to create something nice. In Windows 7 (I suppress the existence of Windows Vista...) such a theme could well be used to increase readability to a level before Aero Glass again. I mean, you cannot really tell whether a Glass window is active or not. I've been tweaking the colours and transparency levels a lot recently but the only safe indicator is the close button: it's red when the window is active, it's colourless otherwise. Then there's the window title. It is always painted black, on however dark a background. Again, regardless of whether the window is active or not. Turning off Aero is not an option in Windows 7 anymore. Classic design looks just ugly there. It already wasn't exactly looking good on XP with the wide start menu. So, can we increase the readability of the Windows 7 UI with themes like in XP or didn't Microsoft learn a thing since the Windows 7 Preview "Vista"?

  • Cannot Add Particular Word to Dictionary

    - by WCWedin
    I am trying to add a particular word to my custom dictionary using Word 2007. (The word happens to be "deserialized".) When I right-click on the word and click Add to Dictionary, the red underline does not go away. When I use the Spelling & Grammar tool from the Review tab on the ribbon, it will stop on that word; clicking the Add to Dictionary button has no effect. Oddly, I am able to add other words to the custom dictionary without a problem. I recently added "deserializes", for instance. I have only encountered this problem with that one particular word. Does anyone know what might be wrong and how I might fix it? Clarifications My document and all its content is set to English (United States). My custom dictionary is set to apply to All Languages, which is the default value. "Serialize" is in the US English default dictionary, but "deserialize" and its various forms is not.

  • Paranormal activity in My Pictures folder: Thumbnail doesn't match actual picture.

    - by Sam152
    After finding an amusing picture on a popular imageboard, I decided to save it. A few days past and I was browsing my images folder when I realised that the thumbnail generated by Windows XP in the thumbnails view did not match the actual image. Here is a comparison image: What's even stranger in this situation is that the parts of the photograph that are different have actually been replaced with what might be the correct background. Furthermore, it is a jpeg (no PNG transparency tricks) that is 343 kilobytes but only 847x847 pixels wide. What could be going on here? Could there be anything malicious in the works, or hidden data? Before anyone asks, I have checked and preformed the following: Deleted Thumbs.db to reload thumbnails. Opened image in different editors. (they appear with the text) Moved image to a different directory. Changed the extension to .rar. All these steps produce the same results. Pre actual posting update: It seems that opening the image in paint, changing the image entirely (deleting entire contents and making a red fill) will still generate the original thumbnail, even after deleting Thumbs.db etc. I'm also hesitant to post the original data, in case there is something malicious or hidden that could be potentially illegal. (Although it would be very beneficial to see if it works on other computers and not just my own).

  • Nagios: turn off service checks/display on down hosts

    - by Alien Life Form
    I want to to tweak nagios in such a way that all checking stops (with services not displayed, or displayed as unknown) for any down node. Said differently I only want to see one alert for a down host instead of 1 (down) + n (1 for every service). Note that I am interested in service display/status, not only in turning off notifications. Rationale: we use the nagios firefox/chrome plugin to monitor status and nagios' behavior is too noisy giving readings like these (because every node has 20 services): 3 down, 1 unreachable, 4 warnings, 87 critical This means that the 7 critical services on up node (the problem is on the service) are swamped in a slab of red services which are critical only because they sit on a node that's down/unreachable. What I'd rather like to see is: 3 down, 1 unreachable, 80 unknown, 4 warnings, 7 critical Or even 3 down, 1 unreachable, 4 warnings, 7 critical I have looked in service dependencies but I did not fine a way to describe: "make all services on a alive-host dependen on the status of the host check". I found the problem discussed here, where one of the participants thought it was a nagios bug, and here where one of the participants thought it was "as designed". As things are, I am just interested in the effect, much less in the design philosophy. Note that this nagios is checking hundreds of nodes, so the maintainablilty of the solution is also important. TIA and cheers.

  • I really need help resolving a Window Vista BSOD (Blue Screen Crash) on my desktop

    - by anonymous
    Hi, thanks for taking the time to read this. I'll get straight to the details. My desktop is on the fritz; it keeps going to blue screen with the stop message of 0x0000007E immediately after the loading bar of vista, right before transitioning to the account selection screen. My desktop runs on a dual-core 32-bit processor with windows Vista Home(?) installed. I have 3 GB of ram as two separate modules, a 1GB acer module and a 2GB geil module. I have an ati video card, unfortunately I cannot recall the exact name but the chipset is ATI and the manufacturer is Sapphire and the card is on the lower end. My hard drive is 320GB (i think) partitioned into two. The C:\ partition is red lined, while the D:\ partition is still pretty empty. As per the advice of my friend, i tried restarting the system with the graphics card removed. Upon failure, i repeated the process removing one RAM module one at a time, but the system still failed to load. Vista would attempt to repair the system and it would initially report that the system was fixed, but vista really failed to fix the problem. After removing the memory modules, vista started to report it's inability to fix the problem. I tried running on safe mode and the driver listing would always stop at crcdisk.sys. I ran memory diagnostics using the windows memory diagnostic tool found in the screen after vista's failed attempt to fix the problem with no luck. the problem details are as such: Problem Event Name : StartupRepairV2 Problem Signature 01: AutoFailover 02: (vista's version number?) 03: 6 04: 720907 05: 0x7e 06: 0x7e 07: 0 08: 2 09: WrpRepair 10: 0 OS Version: 6.0.6000.2.0.0.256.1 Locale ID 1033 any correct advice would be appreciated as i really need my pc to work so i can work on my projects. kinda sad, but i'm college of computer science and i have no idea what to do :P

  • "Windows failed to start" loop with 0xc0000225. No install discs, EasyRE/USB iso hasn't worked

    - by mvidaure
    I've been suffering from this "Windows failed to start" loop with 0xc0000225 for 3 days now and I still can't fix it. The major problem is that I don't have any sort of installation disc. However, I have tried EasyRE via both CD and USB but both result in the same problem.  I try to perform an 'Automated Repair' on my computer and I get in red text "The selected partition is corrupted and could not be accessed or repaired. Please select a different drive to continue." It is also labeled as NO under Active. Since I do not have a the installation discs, I made a USB with a Windows_7_Recovery_Disc  iso (as shown here http://www.sevenforums.com/tutorials/31541-windows-7-usb-dvd-download-tool.html) but it also doesn't work. I get a blue screen that says "RECOVERY You pc needs to be repaired. The application or operating system could not be uploaded because a required file is missing or contains errors... File:\WINDOWS\system32\winload.efi Error code: 0xc0000225 You'll need to use the recovery tools on your installation media. If you don't have any installation media, contact your system administrator or PC manufacturer." Thanks in advance! Miguel

  • NGINX + PHP-FPM - Strange issue when trying to display images via php-gd / readfile - Connection wont terminate

    - by anonymous-one
    Ok, to get the details out of the way: The php script can be anything as simple as: <? header('Content-Type: image/jpeg'); readfile('/local/image.jpg'); ?> When I try to execute this via nginx + php-fpm what happens is the image shows up in the browser, here is what happens: IE - The page stays blank for a long period of time, and eventually the image is shown. Chrome - The image shows, but the loading spinner spins and spins for a long period of time. Eventually the debugger will show the image in red as in error, but the image shows up fine. Everything else on the server works great. Its pushing out about 100mbit steady serving static content. So this is definatly a php-fpm related issue. I THINK this may have something to do with the chunked encoding being sent back wrong? Also, I threw in a pause before the image was read, and got the pid of the fpm process, and it looks as tho its terminatly correctly (from strace): shutdown(3, 1 /* send */) = 0 recvfrom(3, "\1\5\0\1\0\0\0\0", 8, 0, NULL, NULL) = 8 recvfrom(3, "", 8, 0, NULL, NULL) = 0 close(3) = 0 The above was dumped long before ie/chrome decided to give up (even tho the image was shown) loading the image. Displaying HTML / text content is fine. Big bodies etc all load nice and fast and terminate right away (as they should). Doing something like: THIS IS THE IMAGE ---BINARY DUMP OF IMAGE--- Works fine too. Any ideas?

  • Allocating More Than 4 GB Of Memory

    - by TPatti
    I am facing an issue with memory allocation. I have: Host OS: Microsoft Windows XP - Professional x64 Edition - Version 2003 - Service Pack 2. Host Physical Memory: 8 GB Guest OS: Red Hat Enterprise Linux WS release 4 (Nahant Update 5). I am not sure if it is 32 or 64 bits. The lsb_release -a command says that argument LSB Version: core-3.0-ia32, so I guess that would be 32 bits... VMware Player Version: 2.5.2 build-156735 I would like that VMware Player could allocate more that 4 GB, but when I go to the setting, it only lists 4 GB. If I choose the "About" option, it actually says that I have 8 GB installed in the host machine. This VMware image created by someone else and provided to me, apparently done with VMware Workstation 5. Why can't I allocate 8 GB? Where is the problem? In the WMware Player Version, Guest OS or Host OS? How can I solve this? I understand that for this version of player there isn't one version for 32 and another for 64 bits.

  • What is a good replacement for StumbleUpon's Share feature?

    - by Mofoo
    I've been using Firefox + StumbleUpon's Share feature with my friends for years now. It is a perfect way of sharing links directly with your friends. You first need to be Following each other and then on the SU toolbar, you can "Share" with your list of friends. You can even include a personal message. The friend will receive a notification with # of pending shares in their toolbar (bold & red). They click the stumble button and it will navigate to the site plus show a yellow bar with your message. I literally use it daily. But then Chrome came along and beat the tar out of Firefox (and other browsers) in terms of usability and performance. But it doesn't (and never will according to Google) allow toolbars. StumbleUpon's solution in Chrome is a fake toolbar (html) that gets injected into the page you're viewing. It's buggy and performance is low. Overall it's not an acceptable solution. I'm looking for a replacement with something that is just as easy to send/receive links. I was thinking of Twitter DM's and using a bookmarklet, but I wanted to survey the collective for other options Thanks in advance for your input!

  • Is it possible to ack nagios alerts from the terminal on a remote workstation?

    - by cat pants
    I have nagios alerts set up to come through jabber with an http link to ack. Is is possible there is a script I can run from a terminal on a remote workstation that takes the hostname as a parameter and acks the alert? ./ack hostname The benefit, while seemingly mundane, is threefold. First, take http load off nagios. Secondly, nagios http pages can take up to 10-20 seconds to load, so I want to save time there. Thirdly, avoiding slower use of mouse + web interface + firefox/other annoyingly slow browser. Ideally, I would like a script bound to a keyboard shortcut that simply acks the most recent alert. Finally, I want to take the inputs from a joystick, buttons and whatnot, and connect one to a big red button bound to the script so I can just ack the most recent nagios alert by hitting the button lol. (It would be rad too if the button had a screen on the enclosure that showed the text of the alert getting acked lol) Make fun of me all you want, but this is actually something that would be useful to me. If I can save five seconds per alert, and I get 200 alerts per day I need to ack, that's saving me 15 minutes a day. And isn't the whole point of the sysadmin to automate what can be automated? Thanks!

  • Changing the name of a binary packaged application and its evoking command

    - by jerkstore
    I have taken the source code of a large project, App A, and made many modifications to it to produce my version, App B. Both App A and App B compile cleanly on Debian and Red Hat and now I would like to build binary packages for both platforms. The last modification I need to make is ensuring App B can be installed alongside App A without any interference. I should be able to evoke both application-a and application-b in the terminal and have both be listed as separate software in whatever desktop environment is present. The projects have a debian/ folder (containing rules, control, etc.) and an rpm/ folder containing a SPEC file. Currently, building and installing the .rpm and .deb packages works except that App B is recognized as App A and therefore does not meet the aforementioned requirements. ldd shows the programs have the same exact dependencies and I am not able to pursue static linking of libraries. What modifications do I need to make to my project to achieve the desired outcome? Please be specific as I do not have much experience with the packaging process.

  • What are the ways to build a failover cluster?

    - by light
    I have a task where I need to build a failover cluster in two cases: first with servers on Red Hat Enterprise 5.1 and second with SUSE Linux Enterprise 11 SP1. Both cases have SAN. I know there are many ways to build failover cluster, but I can’t find out more, so I need next: The ways to build it? I know only virtualization. Any good book or resource to broad my mind? I’ll be glad to hear any suggestion. Thanks! EDIT #1: failover of servers with bussiness application on it. EDIT #2: will be great to hear summary about solutions with SLES servers? EDIT #3: So if I understand correctly, in my cases the main ways are to use internal solutions or virtualization. So now I have additional questions: Does manufacturer of blades provide some solution? For example HP or IBM. (Without virtualization) Do I need additional server to control "heartbeat" between main and redundant servers? (Virtualization) For example I have several physical servers with VMs. Do I need additional server to control availability of VMs and to move VMs to another physical server in the case their physical server failure? Sorry for my poor English. EDIT #4: Failover of VM or OS on physical server. In both cases will be used SAN , it's not specified, but I think with file system image on it. I started to think that my question is stupid and I need to remake it.

  • Help with Backup Scheme for B.E 12.5

    - by Jemartin
    I'm in process of implementing a new backup scheme. I would say that I'm kind of new to it. So here my question. I'm currently using Backup Exec 12.5 on Windows Server 2008 w/Hyper-V, and IBM Adic Scalar 24. I currently backup our mail server, SQL DB, Board Server Linux Red Hat, Ftp, etc. To a Near-line which is local on our SAN I have the daily's go there as well as full. I would like to start weekly full to tape on a Saturday it takes about 2-3 days to complete the entire full to tape due to backing up from our Co-Lo as well. I have read up on the Father/son rotation but here's my issue with that I dont use tapes everyday only on the weekly full to tape will I be using them. So if there is 4 weeks in a month would I rotate in this order ( Month June WK1 =7tapes , June WK2=7 tapes, June WK3=7tapes June Wk4=7tapes with WK4 being the last tape for the month of June I would use that as a Month tape. For the month of July Wk1= June's WK1 tapes, July WK2= June's WK2 tapes July WK4 = Junes Wk4 tape for a month or would I use a set of new tapes for the last week in July. All tapes are being taking off site as well.

  • Windows XP to remote server 2008 R2 shares - awful response times

    - by nick3216
    I have a network infrastructure of Windows XP clients (a mix of XP and 64-bit XP), that are accessing a network share on a Windows 2008 R2 server. Whenever users type the address of a folder into the address bar of Windows Explorer it's as snappy at determining the contents of the current folder and presenting them to you in the address bar as if you're working on a local drive. But if you open one of the subfolders users get the animated red torch and 'Searching for items...' dialog, typically for 45 seconds. Similarly when using the open folder dialog to try and select a subfolder on this share it takes, on average, 45 seconds for the dialog to expand each node and show the subfolders of each node. Also, while the Explorer instance accsesing the network share is running slowly users notice that the performance of all other Explorer windows suffers. So while Explorer is searching for files on the network share they can't switch to another task and navigate around their local drive using Explorer because it's now as slow as a dead dog at accessing anything. Are there any settings we can change which will improve the performance accessing network shares?

  • jQuery $.ajax response empty, but only in Chrome

    - by roguepixel
    I've exhausted every avenue of research to solve this one so hopefully someone else will think of something I just didn't. Relatively straight forward setup, I have a html page with some javascript that makes an ajax request to a URL (in the same domain) the java web app in the background does its stuff and returns a partial html page (no html, head or body tags, just the content) which should be inserted at a particular point in the page. All sounds pretty easy and the code I have works in IE, Firefox and Safari, but not in Chrome. In Chrome the target element just ends up empty and if I look at the resource request in Chromes developer tools the response content is also empty. All very confusing, I've tried a myriad of things to solve it and I'm just out of ideas. Any help would be greatly appreciated. var container = $('#container'); $.ajax({ type: 'GET', url: '/path/to/local/url', data: data('parameters=value&another=value2'), dataType: 'html', cache: false, beforeSend: requestBefore, complete: requestComplete, success: requestSuccess, error: requestError }); function data(parameters) { var dictionary = {}; var pairs = parameters.split('&'); for (var i = 0; i < pairs.length; i++) { var keyValuePair = pairs[i].split('='); dictionary[keyValuePair[0]] = keyValuePair[1]; } return dictionary; } function requestBefore() { container.find('.message.error').hide(); container.prepend('<div class="modal"><div class="indicator">Loading...</div></div>'); } function requestComplete() { container.find('.modal').remove(); } function requestSuccess(response) { container.empty(); container.html(response); } function requestError(response) { if (response.status == 200 && response.responseText == 'OK') { requestSuccess(response); } else { container.find('.message.error').fadeIn('slow'); } } All of this is executed in a $(document).ready(function() {}); Cheers, Jim @Oleg - Additional information requested, an example of the response that the ajax call might receive. <p class="message error hidden">An unknown error occured while trying to retrieve data, please try again shortly.</p> <div class="timeline"> <a class="icon shuttle-previous" rel="max_id=16470650733&page=1&q=something">Newer Data</a> <a class="icon shuttle-next" rel="max_id=16470650733&page=3&q=something">Older Data</a> </div> <ol class="social"> <li class="even"> <div class="avatar"> <img src="sphere_normal.gif"/> </div> <p> Some Content<br/> <span class="published">Jun 18, 2010 11:29:05 AM</span> - <a target="_blank" href="">Direct Link</a> </p> </li> <li class="odd"> <div class="avatar"> <img src="sphere_normal.gif"/> </div> <p> Some Content<br/> <span class="published">Jun 18, 2010 11:29:05 AM</span> - <a target="_blank" href="">Direct Link</a> </p> </li> </ol> <div class="timeline"> <a class="icon shuttle-previous" rel="max_id=16470650733&page=1&q=something">Newer Data</a> <a class="icon shuttle-next" rel="max_id=16470650733&page=3&q=something">Older Data</a> </div>

  • Version Assemblies with TFS 2010 Continuous Integration

    - by Steve Michelotti
    When I first heard that TFS 2010 had moved to Workflow Foundation for Team Build, I was *extremely* skeptical. I’ve loved MSBuild and didn’t quite understand the reasons for this change. In fact, given that I’ve been exclusively using Cruise Control for Continuous Integration (CI) for the last 5+ years of my career, I was skeptical of TFS for CI in general. However, after going through the learning process for TFS 2010 recently, I’m starting to become a believer. I’m also starting to see some of the benefits with Workflow Foundation for the overall processing because it gives you constructs not available in MSBuild such as parallel tasks, better control flow constructs, and a slightly better customization story. The first customization I had to make to the build process was to version the assemblies of my solution. This is not new. In fact, I’d recommend reading Mike Fourie’s well known post on Versioning Code in TFS before you get started. This post describes several foundational aspects of versioning assemblies regardless of your version of TFS. The main points are: 1) don’t use source control operations for your version file, 2) use a schema like <Major>.<Minor>.<IncrementalNumber>.0, and 3) do not keep AssemblyVersion and AssemblyFileVersion in sync. To do this in TFS 2010, the best post I’ve found has been Jim Lamb’s post of building a custom TFS 2010 workflow activity. Overall, this post is excellent but the primary issue I have with it is that the assembly version numbers produced are based in a date and look like this: “2010.5.15.1”. This is definitely not what I want. I want to be able to communicate to the developers and stakeholders that we are producing the “1.1 release” or “1.2 release” – which would have an assembly version number of “1.1.317.0” for example. In this post, I’ll walk through the process of customizing the assembly version number based on this method – customizing the concepts in Lamb’s post to suit my needs. I’ll also be combining this with the concepts of Fourie’s post – particularly with regards to the standards around how to version the assemblies. The first thing I’ll do is add a file called SolutionAssemblyVersionInfo.cs to the root of my solution that looks like this: 1: using System; 2: using System.Reflection; 3: [assembly: AssemblyVersion("1.1.0.0")] 4: [assembly: AssemblyFileVersion("1.1.0.0")] I’ll then add that file as a Visual Studio link file to each project in my solution by right-clicking the project, “Add – Existing Item…” then when I click the SolutionAssemblyVersionInfo.cs file, making sure I “Add As Link”: Now the Solution Explorer will show our file. We can see that it’s a “link” file because of the black arrow in the icon within all our projects. Of course you’ll need to remove the AssemblyVersion and AssemblyFileVersion attributes from the AssemblyInfo.cs files to avoid the duplicate attributes since they now leave in the SolutionAssemblyVersionInfo.cs file. This is an extremely common technique so that all the projects in our solution can be versioned as a unit. At this point, we’re ready to write our custom activity. The primary consideration is that I want the developer and/or tech lead to be able to easily be in control of the Major.Minor and then I want the CI process to add the third number with a unique incremental number. We’ll leave the fourth position always “0” for now – it’s held in reserve in case the day ever comes where we need to do an emergency patch to Production based on a branched version.   Writing the Custom Workflow Activity Similar to Lamb’s post, I’m going to write two custom workflow activities. The “outer” activity (a xaml activity) will be pretty straight forward. It will check if the solution version file exists in the solution root and, if so, delegate the replacement of version to the AssemblyVersionInfo activity which is a CodeActivity highlighted in red below:   Notice that the arguments of this activity are the “solutionVersionFile” and “tfsBuildNumber” which will be passed in. The tfsBuildNumber passed in will look something like this: “CI_MyApplication.4” and we’ll need to grab the “4” (i.e., the incremental revision number) and put that in the third position. Then we’ll need to honor whatever was specified for Major.Minor in the SolutionAssemblyVersionInfo.cs file. For example, if the SolutionAssemblyVersionInfo.cs file had “1.1.0.0” for the AssemblyVersion (as shown in the first code block near the beginning of this post), then we want to resulting file to have “1.1.4.0”. Before we do anything, let’s put together a unit test for all this so we can know if we get it right: 1: [TestMethod] 2: public void Assembly_version_should_be_parsed_correctly_from_build_name() 3: { 4: // arrange 5: const string versionFile = "SolutionAssemblyVersionInfo.cs"; 6: WriteTestVersionFile(versionFile); 7: var activity = new VersionAssemblies(); 8: var arguments = new Dictionary<string, object> { 9: { "tfsBuildNumber", "CI_MyApplication.4"}, 10: { "solutionVersionFile", versionFile} 11: }; 12:   13: // act 14: var result = WorkflowInvoker.Invoke(activity, arguments); 15:   16: // assert 17: Assert.AreEqual("1.2.4.0", (string)result["newAssemblyFileVersion"]); 18: var lines = File.ReadAllLines(versionFile); 19: Assert.IsTrue(lines.Contains("[assembly: AssemblyVersion(\"1.2.0.0\")]")); 20: Assert.IsTrue(lines.Contains("[assembly: AssemblyFileVersion(\"1.2.4.0\")]")); 21: } 22: 23: private void WriteTestVersionFile(string versionFile) 24: { 25: var fileContents = "using System.Reflection;\n" + 26: "[assembly: AssemblyVersion(\"1.2.0.0\")]\n" + 27: "[assembly: AssemblyFileVersion(\"1.2.0.0\")]"; 28: File.WriteAllText(versionFile, fileContents); 29: }   At this point, the code for our AssemblyVersion activity is pretty straight forward: 1: [BuildActivity(HostEnvironmentOption.Agent)] 2: public class AssemblyVersionInfo : CodeActivity 3: { 4: [RequiredArgument] 5: public InArgument<string> FileName { get; set; } 6:   7: [RequiredArgument] 8: public InArgument<string> TfsBuildNumber { get; set; } 9:   10: public OutArgument<string> NewAssemblyFileVersion { get; set; } 11:   12: protected override void Execute(CodeActivityContext context) 13: { 14: var solutionVersionFile = this.FileName.Get(context); 15: 16: // Ensure that the file is writeable 17: var fileAttributes = File.GetAttributes(solutionVersionFile); 18: File.SetAttributes(solutionVersionFile, fileAttributes & ~FileAttributes.ReadOnly); 19:   20: // Prepare assembly versions 21: var majorMinor = GetAssemblyMajorMinorVersionBasedOnExisting(solutionVersionFile); 22: var newBuildNumber = GetNewBuildNumber(this.TfsBuildNumber.Get(context)); 23: var newAssemblyVersion = string.Format("{0}.{1}.0.0", majorMinor.Item1, majorMinor.Item2); 24: var newAssemblyFileVersion = string.Format("{0}.{1}.{2}.0", majorMinor.Item1, majorMinor.Item2, newBuildNumber); 25: this.NewAssemblyFileVersion.Set(context, newAssemblyFileVersion); 26:   27: // Perform the actual replacement 28: var contents = this.GetFileContents(newAssemblyVersion, newAssemblyFileVersion); 29: File.WriteAllText(solutionVersionFile, contents); 30:   31: // Restore the file's original attributes 32: File.SetAttributes(solutionVersionFile, fileAttributes); 33: } 34:   35: #region Private Methods 36:   37: private string GetFileContents(string newAssemblyVersion, string newAssemblyFileVersion) 38: { 39: var cs = new StringBuilder(); 40: cs.AppendLine("using System.Reflection;"); 41: cs.AppendFormat("[assembly: AssemblyVersion(\"{0}\")]", newAssemblyVersion); 42: cs.AppendLine(); 43: cs.AppendFormat("[assembly: AssemblyFileVersion(\"{0}\")]", newAssemblyFileVersion); 44: return cs.ToString(); 45: } 46:   47: private Tuple<string, string> GetAssemblyMajorMinorVersionBasedOnExisting(string filePath) 48: { 49: var lines = File.ReadAllLines(filePath); 50: var versionLine = lines.Where(x => x.Contains("AssemblyVersion")).FirstOrDefault(); 51:   52: if (versionLine == null) 53: { 54: throw new InvalidOperationException("File does not contain [assembly: AssemblyVersion] attribute"); 55: } 56:   57: return ExtractMajorMinor(versionLine); 58: } 59:   60: private static Tuple<string, string> ExtractMajorMinor(string versionLine) 61: { 62: var firstQuote = versionLine.IndexOf('"') + 1; 63: var secondQuote = versionLine.IndexOf('"', firstQuote); 64: var version = versionLine.Substring(firstQuote, secondQuote - firstQuote); 65: var versionParts = version.Split('.'); 66: return new Tuple<string, string>(versionParts[0], versionParts[1]); 67: } 68:   69: private string GetNewBuildNumber(string buildName) 70: { 71: return buildName.Substring(buildName.LastIndexOf(".") + 1); 72: } 73:   74: #endregion 75: }   At this point the final step is to incorporate this activity into the overall build template. Make a copy of the DefaultTempate.xaml – we’ll call it DefaultTemplateWithVersioning.xaml. Before the build and labeling happens, drag the VersionAssemblies activity in. Then set the LabelName variable to “BuildDetail.BuildDefinition.Name + "-" + newAssemblyFileVersion since the newAssemblyFileVersion was produced by our activity.   Configuring CI Once you add your solution to source control, you can configure CI with the build definition window as shown here. The main difference is that we’ll change the Process tab to reflect a different build number format and choose our custom build process file:   When the build completes, we’ll see the name of our project with the unique revision number:   If we look at the detailed build log for the latest build, we’ll see the label being created with our custom task:     We can now look at the history labels in TFS and see the project name with the labels (the Assignment activity I added to the workflow):   Finally, if we look at the physical assemblies that are produced, we can right-click on any assembly in Windows Explorer and see the assembly version in its properties:   Full Traceability We now have full traceability for our code. There will never be a question of what code was deployed to Production. You can always see the assembly version in the properties of the physical assembly. That can be traced back to a label in TFS where the unique revision number matches. The label in TFS gives you the complete snapshot of the code in your source control repository at the time the code was built. This type of process for full traceability has been used for many years for CI – in fact, I’ve done similar things with CCNet and SVN for quite some time. This is simply the TFS implementation of that pattern. The new features that TFS 2010 give you to make these types of customizations in your build process are quite easy once you get over the initial curve.

  • Oracle Fusion Applications: Changing the Game

    - by kellsey.ruppel(at)oracle.com
    Originally posted in the Oracle Profit Magazine, November 2010 Edition. When the order processing system red-flags a customer's credit status, the IT department doesn't get the customer's call. When a supplier misses a delivery date for a key automotive assembly, it's not the CIO who has to answer for the error. Knowledge workers (known in IT circles as "users") are on the front lines when an exception occurs in an established business process. They're also the ones who study sales trends to decide when to open a new store in an up-and-coming neighborhood, which products are most profitable, how employee skill sets are evolving, and which suppliers are most efficient. In short, knowledge workers are masters of business as unusual. Traditional enterprise resource planning (ERP) systems and other familiar enterprise applications excel at automating, managing, and executing standard business processes. These programs shine when everything goes as planned. Life gets even trickier when a traditional application needs to be extended with a new service or an extra step is added to a business process when new products are brought to market, divisions are merged, or companies are acquired. Monolithic applications often need the IT department to step in and make the necessary adjustments--incurring additional costs and delays. Until now. When Oracle unveiled the much-anticipated family of Oracle Fusion Applications at Oracle OpenWorld in September 2010, knowledge workers in particular had a lot to cheer about. Business users will soon have ready access to analytical information and collaboration tools in the context of what they are working on, so they can make better decisions when problems or opportunities arise. Additionally, the Oracle Fusion Applications platform will make it easy for business users to tweak processes, create new capabilities, and find information, often without the need for IT department assistance and while still following company guidelines. And IT leaders will be happy to hear about new deployment options, guided implementation and setup tools, and cost-saving management capabilities. Just as important, the underlying technologies in Oracle Fusion Applications will allow organizations to choose among their existing investments and next-generation enterprise applications so they can introduce innovations at a pace that makes the most business and financial sense. "Oracle Fusion Applications are architected so you don't have to do rip and replace," says Jim Hayes, managing director of the consulting firm Accenture. "That's very important for creating a business case that will get through the steering committee and be approved by the board. It shows you can drive value and make a difference in the near term." For these and other reasons, analysts and early adopters are calling Oracle Fusion Applications a game changer for enterprise customers. The differences become apparent in three key areas: the way we innovate, work, and adopt technology. Game Changer #1: New Standard for InnovationChange is a constant challenge for most businesses, whether the catalysts are market dynamics, new competition, or the ever-expanding regulatory environment. And, in an ongoing effort to differentiate, business leaders are constantly looking for new ways to do business, serve constituents, and bring new products and services to market. In addition, companies face significant costs to keep their applications up-to-date. For example, when a company adds new suppliers to a procurement system, the IT shop typically has to invest time, effort, and even consulting fees for custom integrations that allow various ERP systems to communicate with each other. Oracle Fusion Applications were built on Web services and a modular SOA foundation to ease customizations and integration activities among all applications--whether from Oracle or another vendor. Interfaces and updates written in ubiquitous Java, rather than a proprietary coding language, allow organizations to tap into existing in-house technical skills rather than seek expensive outside specialists. And with SOA, organizations can extend a feature set or integrate with other SOA environments by combining Web services such as "look up customer" into a new business process managed by the BPEL orchestration engine. Flexibility like this has long-term implications. "Because users capture these changes at a higher metadata layer, not in the application's code, changes and additions are protected even as new versions of Oracle Fusion Applications are released," says Steve Miranda, senior vice president of applications development at Oracle. "This is a much more sustainable approach because you don't incur costly customizations that prevent upgrades and other innovations." And changes are easier to make: if one change is made in the metadata, that change is automatically reflected throughout the application interface, business intelligence, business process, and business logic. Game Changer #2: New Standard for WorkBoosting productivity comes down to doing the basics right: running business processes more efficiently and managing exceptions more effectively, so users can accomplish more in the course of a day or spend more quality time with the most profitable customers. The fastest way to improve process efficiency is to reduce the number of steps it takes to execute common tasks, such as ordering office equipment from an internal procurement system. Oracle Fusion Applications will deliver a complete role-based user experience with business intelligence and collaboration capabilities provided in the context of the work at hand. "We created every Oracle Fusion Applications screen by asking 'What does the user need to know?' 'What does he or she need to do?' and 'Who do they need to work with to get the job done?'" Miranda explains. So when the sales department heads need new laptops, the self-service procurement screen will not only display a list of approved vendors and configurations, but also a running list of reviews by coworkers who recently purchased the various models. Embedded intelligence may also display prevailing delivery lead times based on actual order histories, not the generic shipping dates vendors may quote. The pervasive business intelligence serves many other business activities across all areas of the enterprise. For example, a manager considering whether to promote a direct report can see the person's employee profile, with a salary history, appraisal summaries, and a rundown of skills and training. This approach to business intelligence also has implications for supply chain management. "One of the challenges at Ingersoll Rand is lack of visibility in our supply chain," says Mike Macrie, global director of enterprise applications for global industrial firm Ingersoll Rand. "Oracle Fusion Applications are going to provide the embedded intelligence to give us that visibility and give us the ability to analyze those orders at any point in our supply chain." Oracle Fusion Applications will also create a "role-based user experience" that displays a work list of events that need attention, based on user job function. Role awareness guides users with daily lists of action items and exceptions. So a credit manager may see seven invoices with discounts that are about to expire or 12 suppliers that have been put on hold because credit memos are awaiting approval. Individualization extends to the search capabilities of Oracle Fusion Applications. The platform uses Web-style search screens powered by an Oracle enterprise search engine, with a security framework that filters search results so individuals will only see the internal information they're authorized to access. A further aid to productivity is Oracle Fusion Applications' integration with Web 2.0 collaboration and social networking resources for business environments. Hover-over text will reveal relevant contact information whenever the name of a person appears in an Oracle Fusion Application. Users can connect via an online chat, phone call, or instant message without leaving the main application, reducing the time required for an accounts payable staffer to resolve a mismatch between an invoiced charge and the service record, for example. Addresses of suppliers, customers, or partners will also initiate hover-over text to show contact details and Web-based maps. Finally, Oracle Fusion Applications will promote a new way of working with purpose-driven communities that can bring new efficiencies to everything from cultivating sales leads to managing new projects. As soon as a lead or project materializes, the applications will automatically gather relevant participants into an online community that shares member contact information, schedules, discussion forums, and Wiki pages. "Oracle Fusion Applications will allow us to take it to the next level with embedded Web 2.0 tools and the embedded analytics," says Steve Printz, CIO and vice president, supply chain management, at window-and-door manufacturer Pella. "[This] allows those employees today who are processing transactions to really contribute to the success of the company and become decision-makers." Game Changer #3: New Standard for Technology AdoptionAs IT becomes a dominant component of how businesses run and compete, organizations need to lower the cost of implementing applications and introducing new application features. In the past, rolling out new code often required creating a test bed system, moving beta code to a separate system for user feedback, and--once all the revisions were made--moving version one of the software onto production systems, where business users could finally get the needed new features. Oracle Fusion Applications will use a dedicated setup manager application to streamline this process. First, the setup manager will help scope out the project, querying users about their requirements. "From those questions and answers we determine the steps and the order of those steps that will enable that task," Miranda says. Next, system utilities will assign tasks to owners, track completion status, and monitor the overall status of a programming effort. Oracle Fusion Applications can then recommend Web services that allow users to migrate setup choices and steps across all the various deployments of the application. Those setup capabilities automate the migration from test systems to production systems, as well as between different business units that may be using the same application. "The self-service ability of the setup manager helps business users change setups with very little intervention from the IT team," says Ravi Kumar, vice president at IT services company Infosys. "That to me is a big difference from how we've viewed enterprise applications before." For additional flexibility, organizations will be able to adopt Oracle Fusion Applications modules in either of two modes: a single-instance alternative uses one database for all Oracle Fusion Applications, while a "pillar mode" creates separate databases to underpin each application. This means IT departments running any one of Oracle's applications or even third-party applications can plug Oracle Fusion Applications modules into their environment and see additional business value created on top of their existing systems. And Oracle Fusion Applications offer a hybrid approach to deployment. The applications are all software-as-a-service-ready, so customers can choose on-premises, public or private cloud, or a combination of these to suit their business needs. It's that combination of flexibility and a roadmap for the future that may be the biggest game changer of all. "The Oracle Fusion Applications architecture allows us to migrate our company at a pace that's consistent with our business strategy, whereas before we might have had to do it with a massive upgrade," says Macrie of Ingersoll Rand. "We're looking forward to that architecture to really give us more flexibility in how we migrate over time."

  • Microsoft Channel 9 Interviews Mei Liang to Introduce Sample Browser Extension for Visual Studio 2012 and 2010

    - by Jialiang
    This morning, Microsoft Channel 9 interviewed Mei Liang - Group Manager of Microsoft All-In-One Code Framework - to introduce the newest Sample Browser extension for Visual Studio 2012 &2010.   This extension provides a way for developers to search and download more than 4500 code samples from within Visual Studio, including over 700 Windows 8 samples and more than 1000 All-In-One Code Framework customer-driven code samples. Mei shows us not only the extension, but also the standalone version of the Sample Browser.   http://channel9.msdn.com/Shows/Visual-Studio-Toolbox/Sample-Browser-Visual-Studio-Extension   Microsoft All-In-One Code Framework, working in close partnership with the Visual Studio product team and MSDN Samples Gallery, developed the Sample Browser extension for both Visual Studio 2012 and Visual Studio 2010.  As an effort to evolve the code sample use experience and improve developers' productivity, the Sample Browser allows programmers to search, download and open over 4500 code samples from within Visual Studio with just a few simple clicks.  If no existing code sample can meet the needs, developers can even request a code sample easily from Microsoft thanks to the free “Sample Request Service” offered by Microsoft All-In-One Code Framework.  Through innovations, the teams hope to put the power of tens of thousands of code samples at developers’ fingertips. In short 3 months, the Sample Browser Visual Studio Extension has been installed by 100K global users.  It is also selected as one of the six most highly regarded and commonly used tools for Visual Studio that will make your programming experience feel like never before.   Got to love the All-In-One Code Framework team! You guys know this is THE go to source for code samples. Get this extension and you'll never need to leave VS2012 (well except for bathroom trips, but that's TMI anyway... ;) Read More... From: Greg Duncan (Author of CoolThingOfTheDay) 9/6/2011 12:00 AM The one software design pattern that I have used in just about every application I’ve written is “cut-and-paste,” so the new “Sample Browser” – read sample as a noun not an adjective – is a great boon to my productivity. Read More... From: Jim O'Neil (Microsoft Developer Evangelist) 9/28/2011 12:00 AM Install: http://aka.ms/samplebrowservsx Microsoft All-In-One Code Framework also offers the standalone version of Sample Browser.   The standalone version is particularly useful to Visual Studio Express edition or Visual Studio 2008 users, who cannot install the Sample Browser Visual Studio extension.   From Grassroots’ Passion for Developers to the Innovation of Sample Browser This Sample Browser has come a very long way improving the code sample use experience.  The history can be traced back to a grass-root innovation three years ago.   In early 2009, a few MSDN forum support engineers observed that lots of developers were struggling to work in Visual Studio without adequate code samples. Programming tasks seem harder than they should be when you only read through the documentation.  Just a couple of lines of sample code could answer a lot of questions.   They had a brilliant idea: What if we produce code samples based on developers’ frequently asked programming tasks in forums, social networks and support incidents, and then aggregate all our sample code in a one-stop library to benefit developers?  And what if developers can request code samples directly from Microsoft, free of charge?  This small group of grassroots at Microsoft devoted their nights and weekends to prototyping such a customer-driven code sample library.  This simple idea eventually turned into “Microsoft All-In-One Code Framework”, aka. OneCode.  With the support from more and more passionate developers at Microsoft and the leaders in the Community and Online Support team and Microsoft Commercial Technical Services (CTS), the idea has become a continually growing library with over 1000 customer-driven code samples covering almost all Microsoft development technologies.  These code samples originated from developers’ common pains and needs should be able to help many developers.  However, if developers cannot easily discover the code samples, the effort would still be in vain.  So in early 2010, the team started the idea of Sample Browser to ease the discovery and access of these samples.  In just two months, the first version of Sample Browser was finished and released by a passionate developer.  It was a very simple application, only supporting the basic sample offline search.  Users had to download the whole 100MB sample package containing all samples first, and run the Sample Browser to search locally.   Though developers could not search and download samples on-demand, this simple application laid a solid foundation for the team’s continuous innovations of Sample Browsing experience. In 2011, MSDN Samples Gallery had a big refresh.  The online sample experience was brought to a new level thanks to its PM Steven Wilssens and the gallery team’s effort.  Microsoft All-In-One Code Framework Team saw the opportunity to realize the “on-demand” sample search and download feature with the new gallery.  The two teams formed a strong partnership to upload all the customer-driven code samples to MSDN Samples Gallery, and released the new version of Sample Browser to support “on-demand” sample downloading in April, 2011.  Mei Liang, the Group Manager of Microsoft All-In-One Code Framework, was interviewed by Channel 9 to demo the Sample Browser.  Customers love the effort and the innovation!!  This can be clearly seen from the user comments in the publishing page.   It was very encouraging to the team of All-In-One Code Framework. The team continues innovating and evolving the Sample Browser.  They found the Visual Studio product team this time, and integrated the Sample Browsing experience into the latest Visual Studio 2012.  The newly released Sample Browser Visual Studio extension makes good use of Visual Studio 2012 IDE such as the new Quick Launch bar, the code editor, the toolbar and menus to offer easy access to thousands of code samples from within the development environment.   The Visual Studio Senior Program Manager Lead - Anthony Cangialosi, the Program Manager - Murali Krishna Hosabettu Kamalesha, the MSDN Samples Gallery PM – Steven Wilssens, and the Visual Studio Senior Escalation Engineer - Ed Dore shared lots of insightful suggestions with the team.  Thanks to the brilliant cross-group collaboration inside Microsoft, tens of new features including “Local Language Support” and “Favorite Samples”, as well as a face-lifted user interface, were added to further enhance the user experience. Since the new Sample Browser Visual Studio extension was released, it has received over 100 thousand downloads and five-star ratings.  A customer told the team that he officially falls in LOVE with Microsoft All-In-One Code Framework.   The Sample Browser Innovation for Developers Never Stops! The teams would never stop improving the Sample Browser for developers’ easier lives.   The Microsoft All-In-One Code Framework, Visual Studio and MSDN Samples Gallery teams are working closely to develop the next version of Sample Browser.  Here are the key functions in development or in discussion.  We hope to learn your feedback of the effort.  You can submit your suggestions to the official Visual Studio UserVoice site.  We look forward to hearing from you! 1) Offline Sample Search This is one of the top feature requests that we have received for Sample Browser.   The Sample Browser will support the offline search mode so that developers can search downloaded code samples when they do not have internet access.  This is particularly useful to developers in Enterprises with strict proxy settings. 2) Code Snippet Support and Visual Studio Editor Integration Today, the Sample Browser supports downloading and opening sample project.   However, when developers are searching for code samples, a better user experience would be to see the code snippets in the search result first.  Developers can quickly decide if the code snippet is relevant.   They can also drag and drop the code snippet into the Visual Studio Editor to solve some simple programming tasks.  If developers want to learn more about the sample, they can then choose to download the sample project and open it in Visual Studio. 3) Enterprise Sample Sharing and Searching Large enterprises have many code samples for their own internal tools and APIs that are not appropriate to be shared publicly in MSDN Samples Gallery.   In that case, today’s Sample Browser and MSDN Samples Gallery cannot help these Enterprise developers.  The idea is to create a Code Sample Repository in TFS, and provide an additional Visual Studio extension for Enterprise developers to quickly share code samples to TFS.  The Sample Browser can be configured to connect to the TFS Code Sample Repository to search for and download code samples.  This would potentially enable the Enterprise developers to be more productive. 4) Windows Store Sample Browser With the upcoming release of Windows RT and Microsoft Surface, developers are facing a completely new world of application platform.   Not like laptop, people would often use Microsoft Surface in commute and in travel.  Internet may not be available.  Today’s Visual Studio cannot be installed and run on Windows RT, however, our enthusiastic developers would hope to spend every minute on code.  They love code!   The idea is to create a Windows Store version of Sample Browser. Search and download samples from the online Samples Gallery when the user has internet access. Browse the sample code files and learn the sample documentation of downloaded samples with or without internet access.   In addition to the "browse” function, the Sample Browser could further support “bookmark”, “learning notes”, “code review”, and “quick social sharing". Make full use of the new touch and Windows Store App UI to give developers a new “relaxing” code browsing and learning experience, anytime, anywhere. With Windows Store Sample Browser, developers can enjoy A new relaxing and enjoyable experience for developers to learn code samples You do not have to sit in front of desk and formally open Visual Studio to read code samples.  Many developers get sub-health due to staying in front of desk for a very long time.  With Windows RT, Microsoft Surface and this Windows Store Sample Browser combining with the online MSDN Samples Gallery, developers can sit in a sofa, relaxingly hold the tablet and enjoy to learn their beloved sample code with detailed documentation. Anytime, anywhere Whether you have internet access or not, whether you are at home, in office, or in commute/airplane, developers can always easily access and browse the sample code. Lightweight and fast Particularly for learning a small sample project, the Windows Store Sample Browser would be more lightweight and faster to open and browse the sample code. Please submit your feedback and suggestion to Visual Studio UserVoice.  We look forward to hearing from you and deliver a better and better sample use experience.  Happy Coding!   Special Thanks to People working behind the latest release of Sample Browser Visual Studio Extension and the great partnerships!

  • Reusing XSL template to be invoked with different relative XPaths

    - by meomaxy
    Here is my contrived example that illustrates what I am attempting to accomplish. I have an input XML file that I wish to flatten for further processing. Input file: <BICYCLES> <BICYCLE> <COLOR>BLUE</COLOR> <WHEELS> <WHEEL> <WHEEL_TYPE>FRONT</WHEEL_TYPE> <FLAT>NO</FLAT> <REFLECTORS> <REFLECTOR> <REFLECTOR_NUM>1</REFLECTOR_NUM> <COLOR>RED</COLOR> <SHAPE>SQUARE</SHAPE> </REFLECTOR> <REFLECTOR> <REFLECTOR_NUM>2</REFLECTOR_NUM> <COLOR>WHITE</COLOR> <SHAPE>ROUND</SHAPE> </REFLECTOR> </REFLECTORS> </WHEEL> <WHEEL> <WHEEL_TYPE>REAR</WHEEL_TYPE> <FLAT>NO</FLAT> </WHEEL> </WHEELS> </BICYCLE> </BICYCLES> The input is a list of <BICYCLE> nodes. Each <BICYCLE> has a <COLOR> and optionally has <WHEELS>. <WHEELS> is a list of <WHEEL> nodes, each of which has a few attributes, and optionally has <REFLECTORS>. <REFLECTORS> is a list of <REFLECTOR> nodes, each of which has a few attributes. The goal is to flatten this XML. This is the XSL I'm using: <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fn="http://www.w3.org/2005/xpath-functions"> <xsl:output method="xml" encoding="UTF-8" indent="yes" omit-xml-declaration="yes" xml:space="preserve"/> <xsl:template match="/"> <BICYCLES> <xsl:apply-templates/> </BICYCLES> </xsl:template> <xsl:template match="BICYCLE"> <xsl:choose> <xsl:when test="WHEELS"> <xsl:apply-templates select="WHEELS"/> </xsl:when> <xsl:otherwise> <BICYCLE> <COLOR><xsl:value-of select="COLOR"/></COLOR> <WHEEL_TYPE/> <FLAT/> <REFLECTOR_NUM/> <COLOR/> <SHAPE/> </BICYCLE> </xsl:otherwise> </xsl:choose> </xsl:template> <xsl:template match="WHEELS"> <xsl:apply-templates select="WHEEL"/> </xsl:template> <xsl:template match="WHEEL"> <xsl:choose> <xsl:when test="REFLECTORS"> <xsl:apply-templates select="REFLECTORS"/> </xsl:when> <xsl:otherwise> <BICYCLE> <COLOR><xsl:value-of select="../../COLOR"/></COLOR> <WHEEL_TYPE><xsl:value-of select="WHEEL_TYPE"/></WHEEL_TYPE> <FLAT><xsl:value-of select="FLAT"/></FLAT> <REFLECTOR_NUM/> <COLOR/> <SHAPE/> </BICYCLE> </xsl:otherwise> </xsl:choose> </xsl:template> <xsl:template match="REFLECTORS"> <xsl:apply-templates select="REFLECTOR"/> </xsl:template> <xsl:template match="REFLECTOR"> <BICYCLE> <COLOR><xsl:value-of select="../../../../COLOR"/></COLOR> <WHEEL_TYPE><xsl:value-of select="../../WHEEL_TYPE"/></WHEEL_TYPE> <FLAT><xsl:value-of select="../../FLAT"/></FLAT> <REFLECTOR_NUM><xsl:value-of select="REFLECTOR_NUM"/></REFLECTOR_NUM> <COLOR><xsl:value-of select="COLOR"/></COLOR> <SHAPE><xsl:value-of select="SHAPE"/></SHAPE> </BICYCLE> </xsl:template> </xsl:stylesheet> The output is: <BICYCLES xmlns:fn="http://www.w3.org/2005/xpath-functions" xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <BICYCLE> <COLOR>BLUE</COLOR> <WHEEL_TYPE>FRONT</WHEEL_TYPE> <FLAT>NO</FLAT> <REFLECTOR_NUM>1</REFLECTOR_NUM> <COLOR>RED</COLOR> <SHAPE>SQUARE</SHAPE> </BICYCLE> <BICYCLE> <COLOR>BLUE</COLOR> <WHEEL_TYPE>FRONT</WHEEL_TYPE> <FLAT>NO</FLAT> <REFLECTOR_NUM>2</REFLECTOR_NUM> <COLOR>WHITE</COLOR> <SHAPE>ROUND</SHAPE> </BICYCLE> <BICYCLE> <COLOR>BLUE</COLOR> <WHEEL_TYPE>REAR</WHEEL_TYPE> <FLAT>NO</FLAT> <REFLECTOR_NUM/> <COLOR/> <SHAPE/> </BICYCLE> </BICYCLES> What I don't like about this is that I'm outputting the color attribute in several forms: <COLOR><xsl:value-of select="../../../../COLOR"/></COLOR> <COLOR><xsl:value-of select="../../COLOR"/></COLOR> <COLOR><xsl:value-of select="COLOR"/></COLOR> <COLOR/> It seems like there ought to be a way to make a named template and invoke it from the various places where it is needed and pass some parameter that represents the path back to the <BICYCLE> node to which it refers. Is there a way to clean this up, say with a named template for bicycle fields, for wheel fields and for reflector fields? In the real world example this is based on, there are many more attributes to a "bicycle" than just color, and I want to make this XSL easy to change to include or exclude fields without having to change the XSL in multiple places.
