• Understanding this error: apr_socket_recv: Connection reset by peer (104)

  - by matthewsteiner

  So, if I do some benchmarking with apache benchmark (ab), and I use large numbers of requests. Then sometimes in the middle of a test I get this error. I don't even know what it means. So how can I fix it? Or is it just something that will happen if the server gets too many hits anyway? The problem is, if I run 10,000 hits, it'll all run perfectly. If I run it again, it'll get to 4000 and get the error: apr_socket_recv: Connection reset by peer (104) A little about my setup: I have nginx taking static requests and processing dynamic ones to apache. The file in question is served from cache by nginx, so I guess it's probably got to do with how nginx is handling the requests? Ideas?

• Best Practices for Setup and Management of an Open Source Project

  - by VirtuosiMedia

  Later this year I want to release a PHP framework that I've been working on as open source. I do use source control (SVN), but it's on an extremely limited basis. I'm self-taught, I develop by myself and don't have the experience of working with large teams. I have some ideas about what can help make a project successful, but I'm fuzzy on some of the details. Since it's not yet released, I want to do everything I can to set up the right infrastructure from the beginning. What do I need to know in order to setup and manage a successful project? Some ideas that I have to make it successful (beyond marketing it): Good documentation and tutorials Automated unit tests and builds to push update to the website A clear roadmap Bug Tracking integrated with the source control A style guide to keep the code consistent along with clear A forum for the community to get support, share ideas, etc. A good example application built with the framework A blog to keep the community informed Maintaining backwards compatibility wherever possible Some of my questions: How do I setup and automate a one step submit-test-commit-generate API docs-push update to website process? How do I handle (technically) submissions from other users? How can I ensure that those submissions must be approved before being integrated? What are some of the pitfalls that can be avoided in terms of the project community? I'd prefer to have it be as friendly and helpful as possible without a lot of drama. I'd love to learn from your experience on any of these points. If you think I'm missing anything big, please share that as well. Any resources (preferably geared toward a beginner) that you could point me towards would also be greatly appreciated.

• Oracle Enterprise Manager Logs

  - by idea_

  Hi, I'm attempting to investigate the root cause of the following error which occurs each time a users call an Oracle 10g Forms applet: FRM-92102: A network error has occurred. The Forms Client has attempted to reestablish its connection to the Server 1 time(s) without success. Please check the network connection and try again later. Details... Java Exception: java.io.IOException: Connection failure with 503 This error remained after restarting all my system components: HTTP_Server, OC4J_BI_Forms, Web Cache, Reports Server, etc. The only way to clear this issue was to restart the server entirely. During the downtime, web pages were rendered with the PL/SQL cartridge and being served, so it appears as though this was isolated to forms. Does anybody know which log files may provide clues here? Any help would be much appreciated :) Update: If somebody can provide me with a way or reference to increase the capacity of my web server to minimize these errors, I will accept this as the solution.

• How to tell if PAE is hurting me?

  - by James

  I have a couple of servers with 20-30 GB RAM that are running (a variant of) RHEL4. They are currently running the SMP i386 kernel, not x64, not even the hugemem kernel. This means LowMem is confined to < 1G, and thus dentry_cache and ext3_inode_cache to 100M or so each. How can I tell if this is a problem? Here's a typical vmstat report while it's compiling some Java: $ vmstat 10 procs -----------memory---------- ---swap-- -----io---- --system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 1 1 0 19493816 394740 922420 0 0 1058 2292 1491 1020 6 3 80 12 2 1 0 19519480 395244 850156 0 0 1179 1412 1329 1195 9 4 75 12 1 1 0 19557368 392616 828344 0 0 1783 1680 1498 1756 14 5 72 9 I don't like the way bi is nonzero when there is so much memory free. I imagine slabtop could point more directly to the problem but I don't really understand how to interpret its output.

• C# winforms: graphics.DrawImage problem

  - by Tony

  Hi, I have a really strange problem with Graphics.DrawImage method. I have the PictureBox control in the Panel control with AllowScroll property = true. The program cuts the image on small parts basing on the area selected by the user. I load the image 300x547 and select the area (the red rectangle): program properly cuts the image: then, I load another image 427x640: and then, as the result I see that the image is not cut properly. Each img.jpg file has properly width & height but the drawn image is too small: here's the code snippet - it saves the bitmap area selected by the user: Bitmap bmp = new Bitmap(selectedAreaRECT.Width, selectedAreaRECT.Height); Graphics g = Graphics.FromImage(bmp); g.DrawImage(OriginalIMG, 0,0, selectedAreaRECT, GraphicsUnit.Pixel); g.Save(); g.Dispose(); bmp.Save(AppDomain.CurrentDomain.BaseDirectory + @"\Temp\" + "img1.jpg", System.Drawing.Imaging.ImageFormat.Jpeg); As You see, the code is the same for the img1.jpg from image A and from Image B. I'm trying to resolve that stupid problem for too long, I don't know what's the reason of that problem. I tried diffrent constructors of the DrawImage method, with no success

• WPF Grid Row / Column Sizing in Proportion to DesiredSize?

  - by sinibar

  I have two user controls arranged vertically in a grid, both of which can expand to be taller than the grid can accommodate. I've put them in each in a scrollviewer which functionally works. What I want though is to give them them space in proportion to the amount that they want at run time. So if there's 500 height available, the upper control wants 400 and the lower 600, the upper control would get 200 and the bottom 300. I have no idea at design time how much space each will want in proportion to the other, so using 1*, 2* etc. for row height won't work for me. I can hand-code run-time proportional sizing, but am I missing a simple trick in XAML that would get me what I want? Context is as follows (trimmed for brevity)... <Grid> <TabControl> <TabItem> <Grid> <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="*"/> <RowDefinition Height="*"/> </Grid.RowDefinitions> <GroupBox Grid.Row="0" Header="Title Area" /> <ScrollViewer Grid.Row="1" VerticalScrollBarVisibility="Auto"> <UserControl /> </ScrollViewer> <ScrollViewer Grid.Row="2" VerticalScrollBarVisibility="Auto"> <UserControl /> </ScrollViewer> </Grid> </Grid> </TabItem> </TabControl> </Grid>

• Reset Network Load Balancer Connection Pool

  - by bill_the_loser

  I am currently working on load testing a web application on a virtual machine cluster. I am looking for a way to flush the connection pool / NLB cache so that it is like each machine connecting to the NLB is connecting for the first time and doesn't get directed back to the node that it was on last time. This a Windows 2003 Server cluster, behind a Microsoft software based Network Load Balancer. Additional Information: To do the load testing I'm using virtual machines, one for each node on the cluster. Somehow I got two virtual machines connecting to the same node and I'm looking for an easier way to reset those connections without going in to the NLB Manager and stopping and starting each node on the NLB. Update: We went ahead and changed the affinity on all of the nodes of the cluster to none. Now it's a non-issue.

• Optimizing PHP<>MySQL performance

  - by BarsMonster

  I am trying to optimize my PHP<MySQL on this test script: <? for($i=0;$i<100;$i++)//Itterations count $res.= var_dump(loadRow("select body_ru from articles where id>$i*50 limit 100")); print_r($res); ?> I have APC, and article table have an index on id. Also, all these queries are hitting query cache, so sole MySQL performance if great. But when I am using ab -c 10 -t 10 to bench this scipt, I am getting: 100 itterations: ~100req/sec (~10'000 MySQL queries per second) 5 itteration: ~200req/sec 1 itteration: ~380req/sec 0 itteration: ~580req/sec I've tried to disable persistent connections in PHP - it made it slower a bit. So, how can I make it work faster, provided that MySQL is not limiting performance here?

• nginx + varnish + apache differente IPs in VirtualHost Apache

  - by zeusgod

  Hi, My idea is put NGINX as proxy to redirect to Varnish (cache static content) and then proxy to apache with a lot of VirtualHost in different IPs. My problems is that I would know how can configure Varnish to send access to correct IP, I am going explain: NGINX: Listen in: 10.10.10.10, 20.20.20.20 and 30.30.30.30 on ports: 80 and 443 Proxy redirect to Varnish 10.10.10.10:8080, 20.20.20.20:8080 and 30.30.30.30:8080 Varnish: Port: 8080 - THIS IS THE PROBLEM Proxy content not static to Apache on port 8000 - THIS IS THE OTHER PROBLEM Apache2: Listen in: 10.10.10.10:8000, 20.20.20.20:8000 and 30.30.30.30:8000 Response correct VirtualHost This is the idea. When I try with one IP only, all work correctly, because Varnish is only listen in one IP and port and send to backend in one IP and port too. Could you help me to configure Varnish or there is a best way to configure similar scenario please?

• How is my ISP DNS hijacking AFTER all these precautions?

  - by user973917

  In IE9 when I search for anything my ISP hijacks google search and I get this result. To add complication to this I've already changed the default DNS servers (OpenDNS) months ago. This only happens in IE9; even after machine reboots and cache flushing. I even have my router (dd-wrt) intercepting all requests for DNS and I am still getting this result. I have all extensions disabled and there are no toolbars. This is IE9 from M$. This is not malware; it happens all machines with IE installed (even IE7/8).

• how can I stop my sonicwall TZ-210 (SonicOS Enhanced 5.5.1.0-5o) from responding to arp queries on the wan subnet?

  - by IsaacB

  My sonicwall TZ-210 is answering arp queries on the wan subnet (which my isp doesn't like), basically mapping all the wan ips to its own mac address, causing network havoc since it is not set to route those back to the main isp gateway. How the heck can I turn this behavior off? I have already entered in all wan subnet ips in the static arp cache and left them 'unpublished' which I presumed would mean that it did not bother answering arp queries for them. Apparently it did not do the trick. Arp queries are still being answered unfortunately. What can I do? Any suggestions?

• Raid0 performance degradation?

  - by davy8

  Not sure if this belongs here or on SuperUser, feel free to move as appropriate. I've noticed the performance on my RAID0 setup seems to have degraded over the past months. The throughput is fine, but I think the random access time has increased or something. In use I generally see about 1-5mb/sec when loading stuff in Visual Studio and other apps and it doesn't seem like the CPU is bottlenecking as the CPU utilization is pretty low. I don't recall what Access Time used to be, but HD Tune is reporting 12.6ms Read throughput is showing as averaging about 125MB/sec so it should be great for sequential reads. Defrag daily and it shows fragmentation levels low, so that shouldn't be an issue. Additional info, Windows 7 x64, Intel raid controller on mobo, WD Black 500GB (I think 32mb cache) x2.

• Jeditable with jQuery UI Datepicker

  - by BrynJ

  I need to have a click to edit element on a page, that will in turn invoke an instance of the jQuery UI Datepicker. Currently, I'm using JEditable to provide the in place editing, which is working fine. However, I have a date control input that I would like to have appear as a calendar, which is where the fun starts. I've found a Comment in the this blog by Calle Kabo (the page is a little mashed unfortunately) that details a way to do this: $.editable.addInputType("datepicker", { element: function(settings, original) { var input = $("<input type=\"text\" name=\"value\" />"); $(this).append(input); return(input); }, plugin: function(settings, original) { var form = this; $("input", this).filter(":text").datepicker({ onSelect: function(dateText) { $(this).hide(); $(form).trigger("submit"); } }); } }); However, I can't get the above to work - no errors, but no effect either. I've tried placing it within the jQuery document ready function and also outside of it - no joy. My UI Datepicker class is date-picker and my Jeditable class is ajaxedit, I'm sure the above inaction is due to the need to reference them somehow in the code, but I don't know how. Also, the Jeditable control is one of many element ids, if that has a bearing. Any ideas from those more in the know?

• localhost still responses after uninstalling IIS Windows 7

  - by ryanzec

  I was experimenting with IIS and ASP.NET however I want to go back to WAMP as far as my development server stack on my local windows 7 computer. So I disabled the IIS windows program (using Control Panel - Program and Features - Turn Windows Features on or off) and installed WAMP. I then when to localhost in my browser and just got a blank page. I then uninstalled WAMP and tried again and still got the blank page. I cleared my browser all of saved data like cache and still the same effect. I have uninstalled IIS and WAMP however I can't get localhost to return server not found like it usually does. I know the skype can sometimes effect things running on port 80 so I quit that but still it does not work. Is there a way I can figure out what is running on the port and returning me an empty page?

• Versioning SharePoint binary Workflow ASPX task forms

  - by Janis Veinbergs

  Hello. As noted by some developers, workflow versioning is somekind of headache in SharePoint. I`m wondering is there a way I can version my aspx forms? For sure, i can version code behind assemblies, but if markup changes for any of my files in LAYOUTS folder? Is there versioning available for files or do i have to choose new filename for my form? Sorry, i should have been more specific. Yes, i have files under version control (i can restore previous versions etc), but i`m not talking about this kind of version control. But by deploying new Workflow Version, i must not delete old one, because it is still running on many items in SharePoint, but rather , as noted in previous links, deploy new one so i don't break execution of workflows. But workflows will still break if i don't preserve old aspx forms used by users to interact with workflows. So i must ensure that Assemblies with old version numbers used by old workflow exists (this one is ok, i just changed assembly version number and deployed to GAC) I must ensure that old workflow still uses old aspx form used users to interact with workflow, but new workflow version should use new aspx form with more options (how to do this?).

• Using Linode as a proxy server wrapped in DNS to bypass paid internet services

  - by snihalani

  I have a linode server that I use for development. I was thinking of using that as a proxy server. I have noticed that most paid connections allow DNS queries but don't allow http until I pay them. I verified this by flushing my dns cache and nslookup some random websites. How do I create a proxy server that allows me to may be wrap my packets from my computer in DNS packets, relay to my linode server with ssh key authentication and act as a broker? Thanks.

• Non RBAC User Roles and Permissions System: checking the user's City

  - by micha12

  We are currently designing a User Roles and Permissions System in our web application (ASP.NET), and it seems that we have several cases that do no fit within the classical Role-Based Access Control (RBAC). I will post several questions, each devoted to a particular case, this being the first post. We have the following case: not to allow a user view a certain page if the user lives in a particular city. This is a simple case that is coded in the following way: if (User.City == “Moscow”) // Allow the user to view the page. else // Do not allow the user to view this page. Though this case is very simple and straightforward, it has nothing to do with the RBAC. On StackOverflow, someone called this an Attribute-based Access Control. Under the classical RBAC, it seems that this case should be designed like this: introduce a permission “City where the person lives”, this permission will have a property City. Then create a role, add a permission of type “City = Moscow” to it and the assign the role to the user. Looks extremely cumbersome. The question is whether it is acceptable to introduce such non-RBAC approaches to our permissions system – does that break the design or not? This might seem a primitive question, but we found that most applications use pure RBAC, and we started to think that we might be doing something wrong. Thank you.

• What are the limitations of the .NET Assembly format?

  - by McKAMEY

  We just ran into an interesting issue that I've not experienced before. We have a large scale production ASP.NET 3.5 SP1 Web App Project in Visual Studio 2008 SP1 which gets compiled and deployed using a Website Deployment Project. Everything has worked fine for the last year, until after a check-in yesterday the app started critically failing with BadImageFormatException. The check-in in question doesn't change anything particularly special and the errors are coming from areas of the app not even changed. Using Reflector we inspected the offending methods to find that there were garbage strings in the code (which Reflector humorously interpreted as Chinese characters). We have consistently reproduced this on several machines so it does not appear to be hardware related. Further inspection showed that those garbage strings did not exist in the Assemblies used as inputs to aspnet_merge.exe during deployment. Web Deployment Project Output Assemblies Properties: Merge all outputs to a single assembly Merge each individual folder output to its own assembly Merge all pages and control outputs to a single assembly Create a separate assembly for each page and control output In the web deployment project properties if we set the merge options to the first option ("Merge all outputs to a single assembly") we experience the issue, yet all of the other options work perfectly! So my question: does anyone know why this is happening? Is there a size-limit to aspnet_merge.exe's capabilities (the resulting merged DLL is around 19.3 MB)? Are there any other known issues with merging the output of WAPs? I would love it if any Assembly format / aspnet_merge gurus know about any such limitations like this. Seems to me like a 25MB Assembly, while big, isn't outrageous. Less disk to hit if it is all pregen'd stuff.

• WPF DataValidation on a DataTemplate object in an ItemsControl

  - by Matt H.

  I have two datatemplates, both very similar... here is one of them: <DataTemplate x:Key="HeadingTemplate"> <Grid x:Name="mainHeadingGrid" Margin="5,5,30,0" HorizontalAlignment="Stretch"> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto" /> <ColumnDefinition /> </Grid.ColumnDefinitions> <TextBlock Grid.Column="1" Margin="30,3,10,0" Foreground="Black" FontWeight="Bold" HorizontalAlignment="Left" TextWrapping="Wrap"> <TextBlock.Text> <MultiBinding Converter="{StaticResource myHeadingConverter}" ConverterParameter="getRNHeadingTitle" Mode="TwoWay"> <Binding Path="num"/> <Binding Path="name"/> </MultiBinding> </TextBlock.Text> </TextBlock> <TextBox Grid.Column="1" Text="{Binding Path=moreInfo}"/> </Grid> </DataTemplate> I use an selector in my ItemsControl to choose between the two, based on the object it is bound to. I want to use validation to check through all of the properties and put a big exclamation point in front of the whole datatemplate as it is displayed in the itemscontrol. how do I do this? All of the examples I've found explain how to set a ValidationRule on a specific control in the datatemplate, in that control's binding. I want to apply my validation rule to the entire template... Help! :)

• Trigger element's onclick method with JQuery [ASP.NET]

  - by blu

  I have an ASP.NET server control that inherits from CheckBoxList that renders the controls with a UL and LIs. The control is set to AutoPostBack. Markup: <div id="foo"> <ul> <li> <input type="checkbox" onclick="javascript:setTimeout('__doPostBack(..." ... /> <label ... /> </li> </ul> </div> I would like to trigger the JavaScript that is rendered on the CheckBox when the parent LI is clicked. Here is what I have so far: $("#foo li").click(function() { $(this).find("input:eq(0)").trigger("click"); }); This fires a postback in FF 3.x but the event handler in the codebehind is not fired. In IE 7 a script error comes up and the browser just kind of hangs there for a bit then reloads the page. How should I be doing this?

• Mercurial 1.5 pager on Windows

  - by alexandrul

  I'm trying to set the pager used for Mercurial but the output is empty, even if I specify the command in the [pager] section or as the PAGER environment variable. I noticed that the command provided is launched with cmd.exe. Is this the cause of empty output, and if yes, what is the right syntax? Environment: Mercurial 1.5, Mecurial 1.4.3 hgrc: [extensions] pager = [pager] pager = d:\tools\less\less.exe Sample command lines (from Process Explorer): hg diff c:\windows\system32\cmd.exe /c "d:\tools\less\less.exe 2> NUL:" d:\tools\less\less.exe UPDATE In pager.py, by replacing: sys.stderr = sys.stdout = util.popen(p, "wb") with sys.stderr = sys.stdout = subprocess.Popen(p, stdin = subprocess.PIPE, shell=False).stdin I managed to obtain the desired output for the hg status and diff. BUT, I'm sure it's wrong (or at least incomplete), and I have no control over the pager app (less.exe): the output is shown in the cmd.exe window, I can see the less prompt (:) but any further input is fed into cmd.exe. It seems that the pager app is still active in the background: after typing exit in the cmd.exe window, I have control over the pager app, and I can terminate it normally. Also, it makes no difference what I'm choosing as a pager app (more is behaving the same). UPDATE 2 Issue1677 - [PATCH] pager for "hg help" output on windows
