• MVC Portable Areas &ndash; Deploying Static Files

  - by Steve Michelotti

  This is the second post in a series related to build and deployment considerations as I’ve been exploring MVC Portable Areas: #1 – Using Web Application Project to build portable areas #2 – Conventions for deploying portable area static files #3 – Portable area static files as embedded resources As I’ve been digging more into portable areas, one of the things I’ve liked best is the deployment story which enables my *.aspx, *.ascx pages to be compiled into the assembly as embedded resources rather than having to maintain all those files separately. In traditional web forms, that was always the thing to prevented developers from utilizing *.ascx user controls across projects (see this post for using portable areas in web forms).  However, though the aspx pages are embedded, the supporting static files (e.g., images, css, javascript) are *not*. Most of the demos available online today tend to brush over this issue and focus solely on the aspx side of things. But to create truly robust portable areas, it’s important to have a good story for these supporting files as well.  I’ve been working with two different approaches so far (of course I’d really like to hear if other people are using alternatives). Scenario For the approaches below, the scenario really isn’t that important. It could be something as trivial as this partial view: 1: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> 2: <img src="<%: Url.Content("~/images/arrow.gif") %>" /> Hello World! The point is that there needs to be careful consideration for *any* scenario that links to an external file such as an image, *.css, *.js, etc. In the example shown above, it uses the Url.Content() method to convert to a relative path. But this method won’t necessary work depending on how you deploy your portable area. One approach to address this issue is to build your portable area project with MSDeploy/WebDeploy so that it is packaged properly before incorporating into the host application. All of the *.cs files are removed and the project is ready for xcopy deployment – however, I do *not* need the “Views” folder since all of the mark up has been compiled into the assembly as embedded resources. Now in the host application we create a folder called “Modules” and deploy any portable areas as sub-folders under that: At this point we can add a simple assembly reference to the Widget1.dll sitting in the Modules\Widget1\bin folder. I can now render the portable image in my view like any other portable area. However, the problem with that is that the view results in this:   It couldn’t find arrow.gif because it looked for /images/arrow.gif and it was *actually* located at /images/Modules/Widget1/images/arrow.gif. One solution is to make the physical location of the portable configurable from the perspective of the host like this: 1: <appSettings> 2: <add key="Widget1" value="Modules\Widget1"/> 3: </appSettings> Using the <appSettings> section is a little cheesy but it could be better formalized into its own section. In fact, if were you willing to rely on conventions (e.g., “Modules\{areaName}”) then then config could be eliminated completely. With this config in place, we could create our own Html helper method called Url.AreaContent() that “wraps” the OOTB Url.Content() method while simply pre-pending the area location path: 1: public static string AreaContent(this UrlHelper urlHelper, string contentPath) 2: { 3: var areaName = (string)urlHelper.RequestContext.RouteData.DataTokens["area"]; 4: var areaPath = (string)ConfigurationManager.AppSettings[areaName]; 5:   6: return urlHelper.Content("~/" + areaPath + "/" + contentPath); With these two items in place, we just change our Url.Content() call to Url.AreaContent() like this: 1: <img src="<%: Url.AreaContent("/images/arrow.gif") %>" /> Hello World! and the arrow.gif now renders correctly:     Since we’re just using our own Url.AreaContent() rather than the built-in Url.Content(), this solution works for images, *.css, *.js, or any externally referenced files.  Additionally, any images referenced inside a css file will work provided it’s a relative reference and not an absolute reference. An alternative to this approach is to build the static file into the assembly as embedded resources themselves. I’ll explore this in another post (linked at the top).

• MySQL Memory usage

  - by Rob Stevenson-Leggett

  Our MySQL server seems to be using a lot of memory. I've tried looking for slow queries and queries with no index and have halved the peak CPU usage and Apache memory usage but the MySQL memory stays constantly at 2.2GB (~51% of available memory on the server). Here's the graph from Plesk. Running top in the SSH window shows the same figures. Does anyone have any ideas on why the memory usage is constant like this and not peaks and troughs with usage of the app? Here's the output of the MySQL Tuning Primer script: -- MYSQL PERFORMANCE TUNING PRIMER -- - By: Matthew Montgomery - MySQL Version 5.0.77-log x86_64 Uptime = 1 days 14 hrs 4 min 21 sec Avg. qps = 22 Total Questions = 3059456 Threads Connected = 13 Warning: Server has not been running for at least 48hrs.

• The WaitForAll Roadshow

  - by adweigert

  OK, so I took for granted some imaginative uses of WaitForAll but lacking that, here is how I am using. First, I have a nice little class called Parallel that allows me to spin together a list of tasks (actions) and then use WaitForAll, so here it is, WaitForAll's 15 minutes of fame ... First Parallel that allows me to spin together several Action delegates to execute, well in parallel.   public static class Parallel { public static ParallelQuery Task(Action action) { return new Action[] { action }.AsParallel(); } public static ParallelQuery> Task(Action action) { return new Action[] { action }.AsParallel(); } public static ParallelQuery Task(this ParallelQuery actions, Action action) { var list = new List(actions); list.Add(action); return list.AsParallel(); } public static ParallelQuery> Task(this ParallelQuery> actions, Action action) { var list = new List>(actions); list.Add(action); return list.AsParallel(); } }   Next, this is an example usage from an app I'm working on that just is rendering some basic computer information via WMI and performance counters. The WMI calls can be expensive given the distance and link speed of some of the computers it will be trying to communicate with. This is the actual MVC action from my controller to return the data for an individual computer.  public PartialViewResult Detail(string computerName) { var computer = this.Computers.Get(computerName); var perf = Factory.GetInstance(); var detail = new ComputerDetailViewModel() { Computer = computer }; try { var work = Parallel .Task(delegate { // Win32_ComputerSystem var key = computer.Name + "_Win32_ComputerSystem"; var system = this.Cache.Get(key); if (system == null) { using (var impersonation = computer.ImpersonateElevatedIdentity()) { system = computer.GetWmiContext().GetInstances().Single(); } this.Cache.Set(key, system); } detail.TotalMemory = system.TotalPhysicalMemory; detail.Manufacturer = system.Manufacturer; detail.Model = system.Model; detail.NumberOfProcessors = system.NumberOfProcessors; }) .Task(delegate { // Win32_OperatingSystem var key = computer.Name + "_Win32_OperatingSystem"; var os = this.Cache.Get(key); if (os == null) { using (var impersonation = computer.ImpersonateElevatedIdentity()) { os = computer.GetWmiContext().GetInstances().Single(); } this.Cache.Set(key, os); } detail.OperatingSystem = os.Caption; detail.OSVersion = os.Version; }) // Performance Counters .Task(delegate { using (var impersonation = computer.ImpersonateElevatedIdentity()) { detail.AvailableBytes = perf.GetSample(computer, "Memory", "Available Bytes"); } }) .Task(delegate { using (var impersonation = computer.ImpersonateElevatedIdentity()) { detail.TotalProcessorUtilization = perf.GetValue(computer, "Processor", "% Processor Time", "_Total"); } }).WithExecutionMode(ParallelExecutionMode.ForceParallelism); if (!work.WaitForAll(TimeSpan.FromSeconds(15), task => task())) { return PartialView("Timeout"); } } catch (Exception ex) { this.LogException(ex); return PartialView("Error.ascx"); } return PartialView(detail); }

• Free RAM disappears - Memory leak?

  - by Izzy

  On a fresh started system, free reports about 1.5G used RAM (8G RAM alltogether, Ubuntu 12.04 with lightdm and plasma desktop, one konsole window started). Having the apps running I use, it still consumes not more than 2G. However, having the system running for a couple of days, more and more of my free RAM disappears -- without showing up in the list of used apps: while smem --pie=name reports less than 20% used (and 80% being available), everything else says differently. free -m for example reports on about day 7: total used free shared buffers cached Mem: 7459 7013 446 0 178 997 -/+ buffers/cache: 5836 1623 Swap: 9536 296 9240 (so you can see, it's not the buffers or the cache). Today this finally ended with the system crashing completely: the windows manager being gone, apps "hanging in the air" (frameless) -- and a popup notifying me about "too many open files". Syslog reports: kernel: [856738.020829] VFS: file-max limit 752838 reached So I closed those applications I was able to close, and killed X using Ctrl-Alt-backspace. X tried to come up again after that with failsafeX, but was unable to do so as it could no longer detect its configuration. So I switched to a console using Ctrl-Alt-F2, captured all information I could think of (vmstat, free, smem, proc/meminfo, lsof, ps aux), and finally rebooted. X again came up with failsafeX; this time I told it to "recover from my backed-up configuration", then switched to a console and successfully used startx to bring up the graphical environment. I have no real clue to what is causing this issue -- though it must have to do either with X itself, or with some user processes running on X -- as after killing X, free -m output looked like this: total used free shared buffers cached Mem: 7459 2677 4781 0 62 419 -/+ buffers/cache: 2195 5263 Swap: 9536 59 9477 (~3.5GB being freed) -- to compare with the output after a fresh start: total used free shared buffers cached Mem: 7459 1483 5975 0 63 730 -/+ buffers/cache: 689 6769 Swap: 9536 0 9536 Two more helpful outputs are provided by memstat -u. Shortly before the crash: User Count Swap USS PSS RSS mail 1 0 200 207 616 whoopsie 1 764 740 817 2300 colord 1 3200 836 894 2156 root 62 70404 352996 382260 569920 izzy 80 177508 1465416 1519266 1851840 After having X killed: User Count Swap USS PSS RSS mail 1 0 184 188 356 izzy 1 1400 708 739 1080 whoopsie 1 848 668 826 1772 colord 1 3204 804 888 1728 root 62 54876 131708 149950 267860 And after a restart, back in X: User Count Swap USS PSS RSS mail 1 0 212 217 628 whoopsie 1 0 1536 1880 5096 colord 1 0 3740 4217 7936 root 54 0 148668 180911 345132 izzy 47 0 370928 437562 915056 Edit: Just added two graphs from my monitoring system. Interesting to see: everytime when there's a "jump" in memory consumption, CPU peaks as well. Just found this right now -- and it reminds me of another indicator pointing to X itself: Often when returning to my machine and unlocking the screen, I found something doing heavvy work on my CPU. Checking with top, it always turned out to be /usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch -background none. So after this long explanation, finally my questions: What could be the possible causes? How can I better identify involved processes/applications? What steps could be taken to avoid this behaviour -- short from rebooting the machine all X days? I was running 8.04 (Hardy) for about 5 years on my old machine, never having experienced the like (always more than 100 days uptime, before rebooting for e.g. kernel updates). This now is a complete new machine with a fresh install of 8.04. In case it matters, some specs: AMD A4-3400 APU with Radeon(tm) HD Graphics, using the open-source ati/radeon driver (so no fglrx installed), 8GB RAM, WDC WD1002FAEX-0 hdd (1TB), Asus F1A75-V Evo mainboard. Ubuntu 12.04 64-bit with KDE4/Plasma. Apps usually open more or less permanently include Evolution, Firefox, konsole (with Midnight Commander running inside, about 4 tabs), and LibreOffice -- plus occasionally Calibre, Gimp and Moneyplex (banking software I'm already using for almost 20 years now, in a version which did fine on Hardy).

• Drinking Our Own Champagne: Fusion Accounting Hub at Oracle

  - by Di Seghposs

  A guest post by Corey West, Senior Vice President, Oracle's Corporate Controller and Chief Accounting Officer There's no better story to tell than one about Oracle using its own products with blowout success. Here's how this one goes. As you know, Oracle has increased its share of the software market through a number of high-profile acquisitions. Legally combining companies is a very complicated process -- it can take months to complete, especially for the acquisitions with offices in several countries, each with its own unique laws and regulations. It's a mission critical and time sensitive process to roll an acquired company's legacy systems (running vital operations, such as accounts receivable and general ledger (GL)) into the existing systems at Oracle. To date, we've run our primary financial ledgers in E-Business Suite R12 -- and we've successfully met the requirements of the business and closed the books on time every single quarter. But there's always room for improvement and that comes in the form of Fusion Applications. We are now live on Fusion Accounting Hub (FAH), which is the first critical step in moving to a full Fusion Financials instance. We started with FAH so that we could design a global chart of accounts. Eventually, every transaction in every country will originate from this global chart of accounts -- it becomes the structure for managing our business more uniformly. In conjunction, we're using Oracle Hyperion Data Relationship Management (DRM) to centralize and automate governance of our global chart of accounts and related hierarchies, which will help us lower our costs and greatly reduce risk. Each month, we have to consolidate data from our primary general ledgers. We have been able to simplify this process considerably using FAH. We can now submit our primary ledgers running in E-Business Suite (EBS) R12 directly to FAH, eliminating the need for more than 90 redundant consolidation ledgers. Also we can submit incrementally, so if we need to book an adjustment in a primary ledger after close, we can do so without re-opening it and re-submitting. As a result, we have earlier visibility to period-end actuals during the close. A goal of this implementation, and one that we successfully achieved, is that we are able to use FAH globally with no customization. This means we have the ability to fully deploy ledger sets at the consolidation level, plus we can use standard functionality for currency translation and mass allocations. We're able to use account monitoring and drill down functionality from the consolidation level all the way through to EBS primary ledgers and sub-ledgers, which allows someone to click through a transaction appearing at the consolidation level clear through to its original source, a significant productivity enhancement when doing research. We also see a significant improvement in reporting using Essbase cube and Hyperion Smart View. Specifically, "the addition of an Essbase cube on top of the GL gives us tremendous versatility to automate and speed our elimination process," says Claire Sebti, Senior Director of Corporate Accounting at Oracle. A highlight of this story is that FAH is running in a co-existence environment. Our plan is to move to Fusion Financials in steps, starting with FAH. Next, our Oracle Financial Services Software subsidiary will move to a full Fusion Financials instance. Then we'll replace our EBS instance with Fusion Financials. This approach allows us to plan in steps, learn as we go, and not overwhelm our teams. It also reduces the risk that comes with moving the entire instance at once. Maria Smith, Vice President of Global Controller Operations, is confident about how they've positioned themselves to uptake more Fusion functionality and is eager to "continue to drive additional efficiency and cost savings." In this story, the happy customers are Oracle controllers, financial analysts, accounting specialists, and our management team that get earlier access to more flexible reporting. "Fusion Accounting Hub simplifies our processes and gives us more transparency into account activity," raves Alex SanJuan, Senior Director, Record to Report Strategic Process Owner. Overall, the team has been very impressed with the usability and functionality of FAH and are pleased with the quantifiable improvements. Claire Sebti states, "Our WD5 close activities have been reduced by at least four hours of system processing time, just for the consolidation group." Fusion Accounting Hub is an inspiring beginning to our Fusion Financials implementation story. There's no doubt it's going to be an international bestseller!

• MVC Portable Areas &ndash; Static Files as Embedded Resources

  - by Steve Michelotti

  This is the third post in a series related to build and deployment considerations as I’ve been exploring MVC Portable Areas: #1 – Using Web Application Project to build portable areas #2 – Conventions for deploying portable area static files #3 – Portable area static files as embedded resources In the last post, I walked through a convention for managing static files.  In this post I’ll discuss another approach to manage static files (e.g., images, css, js, etc.).  With this approach, you *also* compile the static files as embedded resources into the assembly similar to the *.aspx pages. Once again, you can set this to happen automatically by simply modifying your *.csproj file to include the desired extensions so you don’t have to remember every time you add a file: 1: <Target Name="BeforeBuild"> 2: <ItemGroup> 3: <EmbeddedResource Include="**\*.aspx;**\*.ascx;**\*.gif;**\*.css;**\*.js" /> 4: </ItemGroup> 5: </Target> We now need a reliable way to serve up these static files that are embedded in the assembly. There are a couple of ways to do this but one way is to simply create a Resource controller whose job is dedicated to doing this. 1: public class ResourceController : Controller 2: { 3: public ActionResult Index(string resourceName) 4: { 5: var contentType = GetContentType(resourceName); 6: var resourceStream = Assembly.GetExecutingAssembly().GetManifestResourceStream(resourceName); 7:   8: return this.File(resourceStream, contentType); 9: return View(); 10: } 11:   12: private static string GetContentType(string resourceName) 13: { 14: var extention = resourceName.Substring(resourceName.LastIndexOf('.')).ToLower(); 15: switch (extention) 16: { 17: case ".gif": 18: return "image/gif"; 19: case ".js": 20: return "text/javascript"; 21: case ".css": 22: return "text/css"; 23: default: 24: return "text/html"; 25: } 26: } 27: } In order to use this controller, we need to make sure we’ve registered the route in our portable area registration (shown in lines 5-6): 1: public class WidgetAreaRegistration : PortableAreaRegistration 2: { 3: public override void RegisterArea(System.Web.Mvc.AreaRegistrationContext context, IApplicationBus bus) 4: { 5: context.MapRoute("ResourceRoute", "widget1/resource/{resourceName}", 6: new { controller = "Resource", action = "Index" }); 7:   8: context.MapRoute("Widget1", "widget1/{controller}/{action}", new 9: { 10: controller = "Home", 11: action = "Index" 12: }); 13:   14: RegisterTheViewsInTheEmbeddedViewEngine(GetType()); 15: } 16:   17: public override string AreaName 18: { 19: get { return "Widget1"; } 20: } 21: } In my previous post, we relied on a custom Url helper method to find the actual physical path to the static file like this: 1: <img src="<%: Url.AreaContent("/images/arrow.gif") %>" /> Hello World! However, since we are now embedding the files inside the assembly, we no longer have to worry about the physical path. We can change this line of code to this: 1: <img src="<%: Url.Resource("Widget1.images.arrow.gif") %>" /> Hello World! Note that I had to fully quality the resource name (with namespace and physical location) since that is how .NET assemblies store embedded resources. I also created my own Url helper method called Resource which looks like this: 1: public static string Resource(this UrlHelper urlHelper, string resourceName) 2: { 3: var areaName = (string)urlHelper.RequestContext.RouteData.DataTokens["area"]; 4: return urlHelper.Action("Index", "Resource", new { resourceName = resourceName, area = areaName }); 5: } This method gives us the convenience of not having to know how to construct the URL – but just allowing us to refer to the resource name. The resulting html for the image tag is: 1: <img src="/widget1/resource/Widget1.images.arrow.gif" /> so we can always request any image from the browser directly. This is almost analogous to the WebResource.axd file but for MVC. What is interesting though is that we can encapsulate each one of these so that each area can have it’s own set of resources and they are easily distinguished because the area name is the first segment of the route. This makes me wonder if something like this ResourceController should be baked into portable areas itself. I’m definitely interested in anyone has any opinions on it or have taken alternative approaches.

• Eclipse Indigo very slow on Kubuntu 12.04

  hello fellow ubuntu users! I have a really big problem with my Eclipse Indigo running on Kubuntu 12.04 32bit, Dell Vostro 3500, Intel(R) Core(TM) i5 CPU M480 @ 2.67 (as cat /proc/cpuinfo said).

• How to setup stunnel so that gmail can use my own smtp server to send messages.

  - by igorhvr

  I am trying to setup gmail to send messages using my own smtp server. I am doing this by using stunnel over a non-ssl enabled server. I am able to use my own smtp client with ssl enabled just fine to my server. Unfortunately, however, gmail seems to be unable to connect to my stunnel port. Gmail seems to be simply closing the connection right after it is established - I get a "SSL socket closed on SSL_read" on my server logs. On gmail, I get a "We are having trouble authenticating with your other mail service. Please try changing your SSL settings. If you continue to experience difficulties, please contact your other email provider for further instructions." message. Any help / tips on figuring this out will be appreciated. My certificate is self-signed - could this perhaps be related to the problem I am experiencing?

• Security Access Control With Solaris Virtualization

  - by Thierry Manfe-Oracle

  Numerous Solaris customers consolidate multiple applications or servers on a single platform. The resulting configuration consists of many environments hosted on a single infrastructure and security constraints sometimes exist between these environments. Recently, a customer consolidated many virtual machines belonging to both their Intranet and Extranet on a pair of SPARC Solaris servers interconnected through Infiniband. Virtual Machines were mapped to Solaris Zones and one security constraint was to prevent SSH connections between the Intranet and the Extranet. This case study gives us the opportunity to understand how the Oracle Solaris Network Virtualization Technology —a.k.a. Project Crossbow— can be used to control outbound traffic from Solaris Zones. Solaris Zones from both the Intranet and Extranet use an Infiniband network to access a ZFS Storage Appliance that exports NFS shares. Solaris global zones on both SPARC servers mount iSCSI LU exported by the Storage Appliance.  Non-global zones are installed on these iSCSI LU. With no security hardening, if an Extranet zone gets compromised, the attacker could try to use the Storage Appliance as a gateway to the Intranet zones, or even worse, to the global zones as all the zones are reachable from this node. One solution consists in using Solaris Network Virtualization Technology to stop outbound SSH traffic from the Solaris Zones. The virtualized network stack provides per-network link flows. A flow classifies network traffic on a specific link. As an example, on the network link used by a Solaris Zone to connect to the Infiniband, a flow can be created for TCP traffic on port 22, thereby a flow for the ssh traffic. A bandwidth can be specified for that flow and, if set to zero, the traffic is blocked. Last but not least, flows are created from the global zone, which means that even with root privileges in a Solaris zone an attacker cannot disable or delete a flow. With the flow approach, the outbound traffic of a Solaris zone is controlled from outside the zone. Schema 1 describes the new network setting once the security has been put in place. Here are the instructions to create a Crossbow flow as used in Schema 1 : (GZ)# zoneadm -z zonename halt ...halts the Solaris Zone. (GZ)# flowadm add-flow -l iblink -a transport=TCP,remote_port=22 -p maxbw=0 sshFilter  ...creates a flow on the IB partition "iblink" used by the zone to connect to the Infiniband.  This IB partition can be identified by intersecting the output of the commands 'zonecfg -z zonename info net' and 'dladm show-part'.  The flow is created on port 22, for the TCP traffic with a zero maximum bandwidth.  The name given to the flow is "sshFilter". (GZ)# zoneadm -z zonename boot  ...restarts the Solaris zone now that the flow is in place.Solaris Zones and Solaris Network Virtualization enable SSH access control on Infiniband (and on Ethernet) without the extra cost of a firewall. With this approach, no change is required on the Infiniband switch. All the security enforcements are put in place at the Solaris level, minimizing the impact on the overall infrastructure. The Crossbow flows come in addition to many other security controls available with Oracle Solaris such as IPFilter and Role Based Access Control, and that can be used to tackle security challenges.

• Would this be a good web application architecture?

  - by Gustav Bertram

  My problem Our MVC based framework does not allow us to cache only part of our output. Ideally we want to cahce static and semi-static bits, and run dynamic bits. In addition, we need to consider data caching that reacts to database changes. My idea The concept I came up with was to represent a page as a tree of XML fragment objects. (I say XML, but I mean XHTML). Some of the fragments are dynamic, and can pull their data directly from models or other sources, but most of the fragments are static scaffolding. If a subtree of fragments is completely static, then I imagine that they could unfold into pure XML that would then be cached as the text representation of their parent element. This process would ideally continue until we are left with a root element that contains all of the static XML, and has a couple of dynamic XML fragments that are resolved and attached to the relevant nodes of the XML tree just before the page is displayed. In addition to separating content into dynamic and static fragments, some fragments could be dynamic and cached. A simple expiry time which propagates up through the XML fragment tree would indicate that a specific fragment should periodically be refreshed. A newspaper section or front page does not need to be updated each second. Minutes or sometimes even longer is sufficient. Other fragments would be dynamic and uncached. Typically too many articles are viewed for them to be cached - the cache would overflow. Some individual articles may be cached if they are extremely popular. Functional notes The folding mechanism could be to be smart enough to judge when it would be more profitable to fold a dynamic cached fragment and propagate the expiry date to the parent fragment, or to keep it separate and simple attach to the XML tree when resolving the page. If some dynamic cached fragments are associated to database objects through mechanisms like a globally unique content id, then changes to the database could trigger changes to the output cache. If fragments store the identifiers of parent fragments, then they could trigger a refolding process that would then include the updated data. A set of pure XML with an ordered array of fragment objects (that each store the identifying information of the node to which they should be attached), can be resolved in a fairly simple way by walking the XML tree, and merging the data from the fragments. Because it is not necessary to parse and construct the entire tree in memory before attaching nodes, processing should be fairly fast. The identifiers of each fragment would be a combination of relevant identity data and the type of fragment object. Cached parent fragments would contain references to these identifiers, in order to then either pull them from the fragment cache, or to run their code. The controller's responsibility is reduced to making changes to the database, and telling the root XML fragment object to render itself. The Question My question has two parts: Is this a good design? Are there any obvious flaws I'm missing? Has somebody else thought of this before? References? Is there an existing alternative that I should consider? A cool templating engine maybe?

• IPv6 host route is deleted after PMTU expires

  - by SAPikachu

  I am experimenting my new IPv6 tunnel setup between my local Ubuntu box and a scratch Linode. I set up some docker containers, configured 6in4 tunnel server and IPv6 forwarding on the Linode: # uname -a Linux argo 3.15.4-x86_64-linode45 #1 SMP Mon Jul 7 08:42:36 EDT 2014 x86_64 x86_64 x86_64 GNU/Linux # ip addr .. snipped .. 48: sit-sapikachu: <POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1472 qdisc noqueue state UNKNOWN group default link/sit 106.185.41.115 peer 1.2.3.4 inet6 fd00::1/64 scope global valid_lft forever preferred_lft forever inet6 fe80::6ab9:2973/64 scope link valid_lft forever preferred_lft forever 13: docker0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default link/ether 56:84:7a:fe:97:99 brd ff:ff:ff:ff:ff:ff inet 172.17.42.1/16 scope global docker0 valid_lft forever preferred_lft forever inet6 fc00::1/64 scope global valid_lft forever preferred_lft forever inet6 fe80::5484:7aff:fefe:9799/64 scope link valid_lft forever preferred_lft forever // Docker containers are bridged to docker0 On my local box, I configured a 6in4 tunnel interface to connect to the Linode box, and added a host route to one of the docker container: # uname -a Linux sapikachu-netbox 3.13.0-24-generic #47-Ubuntu SMP Fri May 2 23:30:00 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux # ip addr .. snipped .. 16: sit-argo: <POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1480 qdisc noqueue state UNKNOWN group default link/sit 0.0.0.0 peer 106.185.41.115 inet6 fd00::2/64 scope global valid_lft forever preferred_lft forever inet6 fe80::a97:302/64 scope link valid_lft forever preferred_lft forever inet6 fe80::ac19:1/64 scope link valid_lft forever preferred_lft forever inet6 fe80::c0a8:1f0/64 scope link valid_lft forever preferred_lft forever inet6 fe80::c0a8:1fa/64 scope link valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether *** brd ff:ff:ff:ff:ff:ff .. snipped .. inet6 fd00:0:1::1/64 scope global valid_lft forever preferred_lft forever inet6 fe80::2e0:6fff:fe0e:365e/64 scope link valid_lft forever preferred_lft forever # ip route replace fc00::1875:8606:d8c1:8a9d via fd00::1 # Add route to docker container # ip -6 route .. snipped unrelated routes fc00::1875:8606:d8c1:8a9d via fd00::1 dev sit-argo metric 1024 expires 590sec mtu 1472 fd00::/64 dev sit-argo proto kernel metric 256 fd00:0:1::/64 dev eth0 proto kernel metric 256 fe80::/64 dev sit-argo proto kernel metric 256 (Note that tunnel MTU on my local box is different from the server, this is intentional for testing) After adding the host route to the docker container (fc00::1875:8606:d8c1:8a9d), I can ping the container without problem until the route expires. After that I couldn't get reply any more. If I run ip -6 route in a few seconds after expiration, expiration time of the host route will be a negative number: fc00::1875:8606:d8c1:8a9d via fd00::1 dev sit-argo metric 1024 expires -1sec And output of ip route get fc00::1875:8606:d8c1:8a9d shows that it is routed to my default IPv6 gateway (which fails to route it correctly of course, since the address is not globally routable). After some time, the host route disappears without a trace. This problem won't happen if I do either one of the following things: Set MTU of tunnel on my local box to be the same as the server (1472). The route won't have expiration time in both ip -6 route and ip route get in this case. Instead of adding a host route, add a route with network mask (even /127 works). In this case ip -6 route shows the route without expiration time, ip route get shows expiration time but it will be correctly refreshed after expiration. Although this problem can be easily resolved, I am curious to know why this happens. Is there error in my configuration, or is this a kernel bug?

• Using WKA in Large Coherence Clusters (Disabling Multicast)

  - by jpurdy

  Disabling hardware multicast (by configuring well-known addresses aka WKA) will place significant stress on the network. For messages that must be sent to multiple servers, rather than having a server send a single packet to the switch and having the switch broadcast that packet to the rest of the cluster, the server must send a packet to each of the other servers. While hardware varies significantly, consider that a server with a single gigabit connection can send at most ~70,000 packets per second. To continue with some concrete numbers, in a cluster with 500 members, that means that each server can send at most 140 cluster-wide messages per second. And if there are 10 cluster members on each physical machine, that number shrinks to 14 cluster-wide messages per second (or with only mild hyperbole, roughly zero). It is also important to keep in mind that network I/O is not only expensive in terms of the network itself, but also the consumption of CPU required to send (or receive) a message (due to things like copying the packet bytes, processing a interrupt, etc). Fortunately, Coherence is designed to rely primarily on point-to-point messages, but there are some features that are inherently one-to-many: Announcing the arrival or departure of a member Updating partition assignment maps across the cluster Creating or destroying a NamedCache Invalidating a cache entry from a large number of client-side near caches Distributing a filter-based request across the full set of cache servers (e.g. queries, aggregators and entry processors) Invoking clear() on a NamedCache The first few of these are operations that are primarily routed through a single senior member, and also occur infrequently, so they usually are not a primary consideration. There are cases, however, where the load from introducing new members can be substantial (to the point of destabilizing the cluster). Consider the case where cluster in the first paragraph grows from 500 members to 1000 members (holding the number of physical machines constant). During this period, there will be 500 new member introductions, each of which may consist of several cluster-wide operations (for the cluster membership itself as well as the partitioned cache services, replicated cache services, invocation services, management services, etc). Note that all of these introductions will route through that one senior member, which is sharing its network bandwidth with several other members (which will be communicating to a lesser degree with other members throughout this process). While each service may have a distinct senior member, there's a good chance during initial startup that a single member will be the senior for all services (if those services start on the senior before the second member joins the cluster). It's obvious that this could cause CPU and/or network starvation. In the current release of Coherence (3.7.1.3 as of this writing), the pure unicast code path also has less sophisticated flow-control for cluster-wide messages (compared to the multicast-enabled code path), which may also result in significant heap consumption on the senior member's JVM (from the message backlog). This is almost never a problem in practice, but with sufficient CPU or network starvation, it could become critical. For the non-operational concerns (near caches, queries, etc), the application itself will determine how much load is placed on the cluster. Applications intended for deployment in a pure unicast environment should be careful to avoid excessive dependence on these features. Even in an environment with multicast support, these operations may scale poorly since even with a constant request rate, the underlying workload will increase at roughly the same rate as the underlying resources are added. Unless there is an infrastructural requirement to the contrary, multicast should be enabled. If it can't be enabled, care should be taken to ensure the added overhead doesn't lead to performance or stability issues. This is particularly crucial in large clusters.

• mySQL Optimization Suggestions

  - by Brian Schroeter

  I'm trying to optimize our mySQL configuration for our large Magento website. The reason I believe that mySQL needs to be configured further is because New Relic has shown that our SELECT queries are taking a long time (20,000+ ms) in some categories. I ran MySQLTuner 1.3.0 and got the following results... (Disclaimer: I restarted mySQL earlier after tweaking some settings, and so the results here may not be 100% accurate): >> MySQLTuner 1.3.0 - Major Hayden <[email protected]> >> Bug reports, feature requests, and downloads at http://mysqltuner.com/ >> Run with '--help' for additional options and output filtering [OK] Currently running supported MySQL version 5.5.37-35.0 [OK] Operating on 64-bit architecture -------- Storage Engine Statistics ------------------------------------------- [--] Status: +ARCHIVE +BLACKHOLE +CSV -FEDERATED +InnoDB +MRG_MYISAM [--] Data in MyISAM tables: 7G (Tables: 332) [--] Data in InnoDB tables: 213G (Tables: 8714) [--] Data in PERFORMANCE_SCHEMA tables: 0B (Tables: 17) [--] Data in MEMORY tables: 0B (Tables: 353) [!!] Total fragmented tables: 5492 -------- Security Recommendations ------------------------------------------- [!!] User '@host5.server1.autopartsnetwork.com' has no password set.

• Can this PHP version of SPICE be improved?

  - by Noctis Skytower

  I do not know much about PHP's standard library of functions and was wondering if the following code can be improved in any way.

• Can't join OS X Mavericks to AD Domain

  - by watkipet

  I'm attempting to join an OS X Mavericks (10.9) client to a Windows Server 2008 Active Directory domain, however the bind fails with this error in the OS X client's system.log: Oct 24 15:03:15 host.domain.com com.apple.preferences.users.remoteservice[5547]: -[ODCAddServerSheetController handleOtherActionError: gotError: Error Domain=com.apple.OpenDirectory Code=5202 "Authentication server encountered an error while attempting the requested operation." UserInfo=0x7f9e6cb3e180 {NSLocalizedDescription=Authentication server encountered an error while attempting the requested operation., NSLocalizedFailureReason=Authentication server encountered an error while attempting the requested operation.}, Authentication server encountered an error while attempting the requested operation. I've joined (bound) Ubuntu Linux clients to the same domain with net ads join in the past with no problems (using the same administrative user). I don't have access to any server logs. Here's the GUI error (from Directory Utility) on the OS X client: Here's the GUI error (from User's and Groups) in System Preferences on the OS X client: Update After some Wiresharking I've got some more info: OS X Client - KDC (over UDP): AS_REQ (no padata) OS X Client <- KDC (over UDP): KRB5KDC_ERR_PREAUTH_REQUIRED OS X Client - KDC (over UDP): AS_REQ (this time with PA-ENC-TIMESTAMP in padata) OS X Client <- KDC (over UDP): KRB5KDC_ERR_RESPONSE_TOO_BIG OS X Client - KDC (over TCP): AS_REQ (also with PA-ENC-TIMESTAMP in padata) OS X Client <- KDC (over TCP): KDC_ERR_ETYPE_NOSUPP ...and that's it. This is what I think is going on: The OS X client sends a kerberos request. The KDC says, "You need to pre-authenticate. Try again" The OS X client tries to pre-authenticate (all this so far is over UDP) Something gets lost on our network and the KDC says, "Oops something went wrong" The OS X client switches to TCP and tries again. Over TCP, the KDC says, "You're using an encryption type I don't support" Note that in its padata records, the OS X client is always using "aes256-cts-hmac-sha1-96" as its encryption type. However, in its KDC_REQ_BODY record it lists the aes256-cts-hmac-sha1-96, aes128-cts-hmac-sha1-96, des3-cbc-sha1, and rc4-hmac encryption types. When the KDC comes back with KDC_ERR_ETYPE_NOSUPP, it uses rc4-hmac as its encryption type in its padata record. I know next to nothing about Kerberos, but it seems to me that the OS X client should go ahead and try the rc4-hmac encryption type. However, it does nothing after this.

• Upgrading Redmine, activerecord-mysql2-adapter not recognized

  - by David Kaczynski

  For upgrading Redmine from 1.0.1 to 2.1.2, I need to execute the command: rake db:migrate RAILS_ENV=production However, doing so produces the following error: rake aborted! Please install the mysql2 adapter: gem install activerecord-mysql2-adapter (mysql2 is not part of the bundle. Add it to Gemfile.) I have ran gem install activerecord-mysql2-adapter, but I still get the same error when I try to run the rake ... command.

• Building a VS2010 solution from TFS2008

  - by slugster

  I have a TFS 2008 Build Agent that has been used to build .Net 3.5 applications. I now have a .Net 4.0 app which i want to compile on the same build agent. I have ensured that MSBuild 4.0 is installed on there and all the required componentry is also installed, but i am getting the following MSB4062 error when building: [Any CPU/Release] C:\Program Files\MSBuild\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets(244,5): error MSB4062: The "Microsoft.WebApplication.Build.Tasks.GetSilverlightItemsFromProperty" task could not be loaded from the assembly C:\Program Files\MSBuild\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.Build.Tasks.dll. Could not load file or assembly 'file:///C:\Program Files\MSBuild\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.Build.Tasks.dll' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded. Confirm that the declaration is correct, and that the assembly and all its dependencies are available. I am presuming that i get this because the TFSBuild.proj gets executed by MSBuild 3.5 which in turn means my solution is compiled with MSBuild 3.5. Am i correct with my diagnosis? Is there any way to ensure that TFS2008 uses MSBuild 4.0 for my solution? Can it be done on a single team project so that it doesn't affect any other team projects being built on the same build agent? Note that i have checked the question Build failing - VS2010 solution on TFS2008 and this is not a duplicate. Thanks :)

• What is the difference (if any) between Html.Partial(view, model) and Html.RenderPartial(view,model)

  - by Stephane

  Other than the type it returns and the fact that you call it differently of course <% Html.RenderPartial(...); %> <%= Html.Partial(...) %> If they are different, why would you call one rather than the other one?

• SGEN doesn't work after upgrading from VS2008 to VS2010

  - by emddudley

  I just recently upgraded a VS2008/.NET 3.5 SP1 project to VS2010 and .NET 4. I have a post-build event which calls SGEN to generate the XmlSerializers assembly. Whenever I try to run it I get the following error. "C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\sgen.exe" /debug /force /verbose /c:"platform:x86" "C:\path\to\SomeAssembly.dll" Microsoft (R) Xml Serialization support utility [Microsoft (R) .NET Framework, Version 2.0.50727.3038] Copyright (C) Microsoft Corporation.

Error: An attempt was made to load an assembly with an incorrect format: c:\path\to\someassembly.dll. - Could not load file or assembly 'file:///c:\path\to\someassembly.dll' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded. If you would like more help, please type "sgen /?". I get the same error running SGEN from the command line, but I can't figure out what the problem is. Any ideas?

• NHibernate.Bytecode.UnableToLoadProxyFactoryFactoryException

  - by Shane

  I have the following code set up in my Startup IDictionary properties = new Dictionary(); properties.Add("connection.driver_class", "NHibernate.Driver.SqlClientDriver"); properties.Add("dialect", "NHibernate.Dialect.MsSql2005Dialect"); properties.Add("proxyfactory.factory_class", "NNHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle"); properties.Add("connection.provider", "NHibernate.Connection.DriverConnectionProvider"); properties.Add("connection.connection_string", "Data Source=ZEUS;Initial Catalog=mydb;Persist Security Info=True;User ID=sa;Password=xxxxxxxx"); InPlaceConfigurationSource source = new InPlaceConfigurationSource(); source.Add(typeof(ActiveRecordBase), (IDictionary<string, string>) properties); Assembly asm = Assembly.Load("Repository"); Castle.ActiveRecord.ActiveRecordStarter.Initialize(asm, source); I am getting the following error: failed: NHibernate.Bytecode.UnableToLoadProxyFactoryFactoryException : Unable to load type 'NNHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle' during configuration of proxy factory class. Possible causes are: - The NHibernate.Bytecode provider assembly was not deployed. - The typeName used to initialize the 'proxyfactory.factory_class' property of the session-factory section is not well formed. I have read and read I am referecning the All the assemblies listed and I am at a total loss as what to try next. Castle.ActiveRecord.dll Castle.DynamicProxy2.dll Iesi.Collections.dll log4net.dll NHibernate.dll NHibernate.ByteCode.Castle.dll I am 100% sure the assembly is in the bin. Anyone have any ideas?
