• Trac FastCGI + Python on dreamhost leaves zombie python running

  - by Katsuke

  Hello there, Recently I installed trac in one of my dreamhost domains. I followed the instructions of http://trac.mlalonde.net/wiki/CreamyTrac and everything worked perfectly. At least i thought that was the case. After a few days, i started to notice that i was getting random 500 pages. I quickly checked the error log, and found a bunch of: [Fri Apr 16 14:35:34 2010] [error] [client *.*.*.*] Premature end of script headers: dispatch.fcgi [Fri Apr 16 14:35:54 2010] [error] [client *.*.*.*] Premature end of script headers: dispatch.fcgi, referer: http://www.trac.****.com/login [Fri Apr 16 16:05:58 2010] [error] [client *.*.*.*] Premature end of script headers: dispatch.fcgi, referer: http://www.trac.****.com/timeline The trac instance has very low traffic so it is possible that this might have been triggered faster if there was more use of it. So next step i went to look at top and am amazed by what i see: (this is NOT exactly what i saw, i just reproduced this from memory) 23730 rl_inst 20 0 44516 15m 4012 S 0.0 0.4 0:00.17 python2.4 23731 rl_inst 20 0 44616 15m 4012 S 0.0 0.4 0:03.17 python2.4 23732 rl_inst 20 0 44116 15m 4012 S 0.0 0.4 0:01.17 python2.4 23733 rl_inst 20 0 44826 15m 4012 S 0.0 0.4 0:04.17 python2.4 23734 rl_inst 20 0 44216 15m 4012 S 0.0 0.4 0:02.17 python2.4 23735 rl_inst 20 0 44416 15m 4012 S 0.0 0.4 0:01.17 python2.4 I opened the trac site again and that changed to this: 23730 rl_inst 20 0 44516 15m 4012 S 0.0 0.4 0:00.17 python2.4 23731 rl_inst 20 0 44616 15m 4012 S 0.0 0.4 0:03.17 python2.4 23732 rl_inst 20 0 44116 15m 4012 S 0.0 0.4 0:01.17 python2.4 23733 rl_inst 20 0 44826 15m 4012 S 0.0 0.4 0:04.17 python2.4 23734 rl_inst 20 0 44216 15m 4012 S 0.0 0.4 0:02.17 python2.4 23735 rl_inst 20 0 44416 15m 4012 S 0.0 0.4 0:01.17 python2.4 28378 rl_inst 20 0 2608 1208 1008 S 0.0 0.0 0:00.00 dispatch.fcgi 28382 rl_inst 20 0 44248 15m 4012 S 0.0 0.4 0:02.19 python2.4 So the dispatch.fcgi was being called correctly and was spawning correctly other python2.4 process. After the IDLE time passed this is the results: 23730 rl_inst 20 0 44516 15m 4012 S 0.0 0.4 0:00.17 python2.4 23731 rl_inst 20 0 44616 15m 4012 S 0.0 0.4 0:03.17 python2.4 23732 rl_inst 20 0 44116 15m 4012 S 0.0 0.4 0:01.17 python2.4 23733 rl_inst 20 0 44826 15m 4012 S 0.0 0.4 0:04.17 python2.4 23734 rl_inst 20 0 44216 15m 4012 S 0.0 0.4 0:02.17 python2.4 23735 rl_inst 20 0 44416 15m 4012 S 0.0 0.4 0:01.17 python2.4 28382 rl_inst 20 0 44248 15m 4012 S 0.0 0.4 0:02.19 python2.4 dispatch.fcgi was gone but the corresponding python2.4 was still there o_O. I had started with 5 sleeping processes of python and after idle time i ended up with 6. I repeated this and found that it kept spawning more and more python2.4, this was indeed what was causing my 500s indirectly. Let me explain my findings. Am on a shared hosting so my processes get killed if they are way too many. So everytime i opened trac 2 new processes spawned and one remained, to the point that dreamhost was killing a random process when i reached my limit. Sometimes killing the python2.4 that actually was rendering the current page. Hence header premature ending, python is gone the .fcgi doesnt know what to do and throws an 500. I found a dirty solution to this. I changed my dispatch.fcgi to contain a line that killed any currently running python2.4 process and then spawn a new one. Since then i dont get any rogues what so ever. But i dont think this is the best solution, calling killall in every fcgi just seems wrong. Anyone has run into this issue and found a cleaner solution? Is there anything that i have overlooked?

• How can I include additional markup within a 'Content' inner property of an ASP.Net WebControl?

  - by GenericTypeTea

  I've searched the site and I cannot find a solution for my problem, so apologies if it's already been answered (I'm sure someone must have asked this before). I have written a jQuery Popup window that I've packaged up as a WebControl and IScriptControl. The last step is to be able to write the markup within the tags of my control. I've used the InnerProperty attribute a few times, but only for including lists of strongly typed classes. Here's my property on the WebControl: [PersistenceMode(PersistenceMode.InnerProperty)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] public something??? Content { get { if (_content == null) { _content = new something???(); } return _content; } } private something??? _content; Here's the HTML Markup of what I'm after: <ctr:WebPopup runat="server" ID="win_Test" Hidden="false" Width="100px" Height="100px" Modal="true" WindowCaption="Test Window" CssClass="window"> <Content> <div style="display:none;"> <asp:Button runat="server" ID="Button1" OnClick="Button1_Click" /> </div> <%--Etc--%> <%--Etc--%> </Content> </ctr:WebPopup> Unfortunately I don't know what type my Content property should be. I basically need to replicate the UpdatePanel's ContentTemplate. EDIT: So the following allows a Template container to be automatically created, but no controls show up, what's wrong with what I'm doing? [PersistenceMode(PersistenceMode.InnerProperty)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] public ITemplate Content { get { return _content; } set { _content = value; } } private ITemplate _content; EDIT2: Overriding the CreateChildControls allows the controls within the ITemplate to be rendered: protected override void CreateChildControls() { if (this.Content != null) { this.Controls.Clear(); this.Content.InstantiateIn(this); } base.CreateChildControls(); } Unfortunately I cannot now access the controls within the ITemplate from the codebehind file on the file. I.e. if I put a button within my mark as so: <ctr:WebPopup runat="server" ID="win_StatusFilter"> <Content> <asp:Button runat="server" ID="btn_Test" Text="Cannot access this from code behind?" /> </Content> </ctr:WebPopup> I then cannot access btn_Test from the code behind: protected void Page_Load(object sender, EventArgs e) { btn_Test.Text = "btn_Test is not present in Intellisense and is not accessible to the page. It does, however, render correctly."; }

• Ubuntu 9.10 x86_32 with PAE causes graphics issues, mainly slowness

  - by widgisoft

  I've tried the 64bit version and found I was constantly hitting a brick wall trying to get 32bit stuff to run; I'd previously used PAE on 9.04 without any issues so figured I'd give it a shot. However, on 9.10 it seems PAE or the process of enabling PAE breaks the nvidia drivers/module somewhat as performance is terrible; I can't even enable desktop effects and there's lots of artifacting on random controls. Disabling the pae image and rebooting fixes the issue however I'm then stuck with "only" 2.7Gb of ram and unable to use the full 8gb that's installed. Is there somthing special I need to do when using pae and nVidia drivers or should I be using 64bit and just figure out how to force run 32bit packages? :-p

• Custom realm/starting Tomcat 6.0 from Netbeans 6.8/first HTTP request

  - by Drew

  I'm using NetBeans 6.8 and Tomcat 6.0.xx. I've created a custom realm and updated the NetBeans project build.xml to deploy the realm to Tomcat. When I debug the project, NetBeans starts the Tomcat server and makes an initial HTTP GET request for 'manager/list'. Tomcat graciously hands this request off to my custom realm for authentication. The request gets denied and NetBeans displays the following error in the output window: (note: error is displayed after NetBeans gets access denied) Access to Tomcat server has not been authorized. Set the correct username and password with the "manager" role in the Tomcat customizer in the Server Manager. Do I have something incorrectly configured? How do I prevent NetBeans from issuing this initial request? Thanks, Drew

• SQL server 2005 - user rights

  - by Paresh

  I have created one user named "tuser" with create database rights in SQL server 2005. and given the 'db_owner' database role of master and msdb database to "tuser". From this user login when I run the script for create database then it will create new database. But "tuser" don't have access that newly created database generated from script. Any one have any idea?, I want to write the script so "tuser" have access that new created database after creation and can have add user permission of newly created database. I want to give 'db_owner' database roles to "tuser" on that newly created database in the same script which create new database. The script run under 'tuser'.

• How can i control how much Authority RRs a DNS answer returns ?

  - by Benoît

  Hello, i quite don't understand Authority RRs. Using dig to resolve some random A records, my caching DNS server sometimes also return Authority RRs and sometimes not. The number and the type of the returned Authority RRs also vary a lot. What does control whether Authority RRs are returned or not on a standard client query ? Is it a client or server setting ? What does control how many Authoriy RRs are returned ? What does control of the type of the Authority RRs records returned ? Sometimes it's multiple NS, sometimes it's a SOA. It's also often comes with Additional RRs of type A about the Authority RRs NS returned. I'm really looking for a RFC or kind of describing this. Thanks.

• DHCPD Offering ip address on wrong subnet

  - by Logan

  I just recently added a new subnet for our wireless network to our DHCP configuration for the 192.168.254.0 subnet. Most of the time when wireless clients connect it works just fine. However, sometimes on seemingly random occasions the DHCP server will send out a DHCPOFFER with an IP address on the wrong subnet. Example: dhcpd: DHCPDISCOVER from MACADDRESS (ThinkBook2) via 192.168.254.1 dhcpd: DHCPOFFER on 192.168.22.236 to MACADDRESS (ThinkBook2) via 192.168.254.1 Here is the subnet configuration in dhcpd.conf: subnet 192.168.254.0 netmask 255.255.255.0 { option routers 192.168.254.1; range 192.168.254.34 192.168.254.254; default-lease-time 14400; authoritative; } How can I make sure the server always sends out an IP address on the right subnet?

• Is it feasible to write a Firefox plugin to make use of ActiveX control on Windows?

  - by Gary B2312321321

  I use an ActiveX control called TAPIEx enabling TAPI phone system integration using MS Access 2000 (+Visual Basic). I want to turn this Access database into a web app with the clients running Firefox (all on internal network). Since Firefox doesnt support ActiveX is it feasible for me to write a Firefox plugin that in turn utilizes the ActiveX control? With regard to how plugins work - Would I be able to call 'functions' of the plugin from page script (eg dial call specifying phone number, check if calls in process)? Would adding these functions to the Firefox right click menu 'globally' inside Firefox be easier? Hope you guys can help. Note I'm not a fulltime programmer; I just need to know how steep the learning curve will be or even if my idea is possible! Ive now found a project to allow using activex controls in firefox that seems to be quite up to date at: http://code.google.com/p/ff-activex-host/

• Switching to open folders on a Mac

  - by Charles

  How do I easily switch to an open folder on a Mac? In Windows, which I'm used to using, I can see all my opened folders in my vertical taskbar, all I need to do to switch to another window is click on the folder in the task bar. There's no taskbar on a Mac, and when I have a lot of folders opened, ie. lots of Finder windows, how can I switch between them? The way I'm doing it is, I put expose on an active corner and switch that way. However that's still damn hard, because first I have to bring up expose, and then find my window. The folders are placed in a random position between opened apps, the folders are not in a list, and on a big screen I have to scan the whole screen in order to find the one I want... etc. Is it really this hard just to switch to a different folder on a Mac? Is there a taskbar solution on a Mac?

• Windows Azure: need to know the data processing time

  - by veda

  I have stored some files in the form of blobs on azure and I have written an application that would access these blobs. When I host this application as a web role on azure, it works perfectly and I am happy with that. But now, I wanted to know “what is the query time taken to access each blob file?” I was searching for this through the Microsoft Azure Storage SLA and I found that for GetBlob request type, the maximum processing time should be within the product of 2 seconds multiplied by the number of MBs transferred in processing the request. I am still unclear. What is the actual processing time of my data query? How can I measure it? Can I be able to speed up the processing time? I can understand that the processing time depends on internet speed, location of the data center where my data is being stored, and location of data center where my application is being hosted. But still, will I be able to speed up my query?

• Tomcat 403 error after LDAP authentication.

  - by user352636

  I'm currently trying to use an LDAP server to authenticate users who are trying to access our Tomcat setup. I believe I have managed to get the LDAP authentication working in the form of a JNDI realm call from Tomcat, but immediately after the user enters their password Tomcat starts throwing 403 (permission denied) errors for everything except from the root page (ttp://localhost:1337/). I have no idea why this is happening. I am following the example at http://blog.mc-thias.org/?title=tomcat_ldap_authentication&more=1&c=1&tb=1&pb=1 . server.xml (the interesting/changed bits) <Realm className="org.apache.catalina.realm.JNDIRealm" debug="99" connectionURL="ldap://localhost:389" userPattern="uid={0},ou=People,o=test,dc=company,dc=uk" userSubTree="true" roleBase="ou=Roles,o=test,dc=company,dc=uk" roleName="cn" roleSearch="memberUid={1}" /> <Valve className="org.apache.catalina.authenticator.SingleSignOn" /> web.xml (the interesting/changed bits) <security-constraint> <display-name>Security Constraint</display-name> <web-resource-collection> <web-resource-name>Protected Area</web-resource-name> <!-- Define the context-relative URL(s) to be protected --> <url-pattern>/*</url-pattern> <!-- If you list http methods, only those methods are protected --> </web-resource-collection> <auth-constraint> <!-- Anyone with one of the listed roles may access this area --> <role-name>admin</role-name> <role-name>regular</role-name> </auth-constraint> </security-constraint> <!-- Default login configuration uses form-based authentication --> <login-config> <auth-method>BASIC</auth-method> </login-config> <!-- Security roles referenced by this web application --> <security-role> <role-name>admin</role-name> <role-name>regular</role-name> </security-role> I cannot access my LDAP setup at the moment, but I believe it is alright as the login is accepted by the BASIC auth method, it's just tomcat that is rejecting it. The roles should be as defined in web.xml - admin and regular. If there is any other information you require me to provide, please just ask! My thanks in advance to anyone who can help, and my apologies for any major mistakes I have made - yesterday was pretty much the first time I'd ever heard of LDAP =D. EDIT: Fixed the second xml segment. Apologies for the formating-fail.

• Impersonation and Delegation

  - by Samuel Kim

  I am using impersonation is used to access file on UNC share as below. var ctx = ((WindowsIdentity)HttpContext.Current.User.Identity).Impersonate(); string level = WindowsIdentity.GetCurrent().ImpersonationLevel); On two Windows 2003 servers using IIS6, I am getting different impersonation levels: Delegation on one server and Impersonation on the other server. This causes issues where I am unable to access the UNC share on the server with 'Impersonation' level. What could be causing this difference? I searched through machine.config and IIS settings for the app pool, site and virtual directories - but aren't able to find the cause of this problem.

• Strange IIS/Asp.net Exception Message

  - by Element

  I have a standard asp.net 2.0 application running on IIS 6. I have noticed some strange exception messages in the logs. They seem to be caused by random spam bots trying to submit forms. They are strange because the request string is huge and all the exception details in the event manager are messed up, they have been replaced with %21,%22, etc.. as seen in the screen shot. Is this some kind of exploit or just a bug in the asp.net exception handler/logger ? UPDATE: I traced the requests that are causing this strange log event to a bug in IE8 that causes it to request scriptresource.axd?d={html from page} as described in these links: MS Connect SO - Invalid Webresource.axd SO - IE8 Dropping Memory Pages I am still not sure why these requests would break the IIS log event like seen above, they are just long strings of jiberish being sent to the server, maybe someone reading this can shed some light on it.

• Freezing with black screen after booting OS with AMD Catalyst driver

  - by Oleg

  I have ATI Mobility Radeon HD 5470 on my HP laptop. A few weeks ago I was confused with a weird trouble in proprietary drivers for my graphics card. When I start X server (or just boot Windows) system sometimes totally hangs up with black screen. The most annoying thing is that issue appearing is absolutely random (2 success, 3 fails, 1 success, 7 fails, etc.). It appears both on Linux (Arch, Debian 7) and Windows XP. I've tried reinstalling OS, drivers, etc. I've also tried updating BIOS. Then boot was successful for the next few times and issue appeared again (probably it was just a coincidence, because another BIOS updates gave no results). I really don't know what to do. Any ideas?

• Broadcast-style Bluetooth using Sockets on the iPhone?

  - by Kyle

  Is there any way to open a broadcast bluetooth socket, take a listen and send replies? I want a proper peer to peer system where I broadcast and listen for broadcasts in an area. That way, variable clients can mingle. Is this possible? My theory is this: If GameKit can sit around wasting 25 seconds of the users time whilst having access to a broadcast socket, can't I? Or, must I be in kernel mode for such access? I'm not really sure where the proper bluetooth headers are as well. Thanks for reading!

• Keyboard lights sometimes stay on after PC is powered off. Why?

  - by Vilx-

  Sometimes when I power off my PC some lights on the keyboard stay on. It's pretty random which ones, though I suspect it has something to do with what lights were on just before the shutdown (if I vigorously follow that they are all off while the PC is shutting down then they stay off). Not that this would change anything, but it is annoying. Why does this happen and how can I avoid it? Added: I know that I can turn off the power completely to my computer and it will go off. That's not the point. Actually, I even want my keyboard to have power, because I use it to turn on my computer (the power button on the case is difficult to reach). I just want the lights to go off. Or at least understand why this happens. Oh, and it's a PS2 keyboard.

• Accessing the feed/entry/id field of an ATOM 1.0 feed with the ROME library

  - by PartlyCloudy

  Hi, I feel a bit stupid asking this question, but I don't know how I can access the ID field of an entry when using ROME to parse an Atom feed. ROME provides it's own meta level of feeds/items, i.e. SyndFeed and SyndEntry. Being an abstraction over RSS and ATOM they only contain elements both formats support. Thus, there is no method to get an ID of an entry. There also exist low level packages for the distinct formats, and the Atom package contains com.sun.syndication.feed.atom.Entry, which provides getId(). However, I don't know how can I convert my SyndEntry into an Entry. I have not found a way to convert it. The (outdated) tutorials show a conversion, but that's only for output though. So how can I easily access the ID field? Thanks in advance.

• Starting x11vnc remotely when X server is already running

  - by Madiyaan Damha

  I have a ubuntu linux machine that I have already logged into and X server is running (it is pass the login manager like gdm). I can access this machine through ssh. My goal is to start x11vnc on this machine and attach it to the X server that is already running. When I ssh into the machine and start x11vnc, it says: X11 was unable to open the X DISPLAY ":0", it cannot continue. How can I start x11vnc on the remote machine if I don't have physical access to it and Xserver has already started. The reason I want to do this is because the remote machine has several windows open that I want to work on. Thanks,

• How does Amarok rip Audio CDs (in Ubuntu Lucid)?

  - by Hanno Fietz

  I'm in the process of moving my CD collection into my Amarok library. Mostly, it works great. Sometimes however, the process just hangs forever. The problem seems to occur at random (i. e. often, but not always at the same disk/track) and the consequences range from none (successful after cancel/retry) to Amarok's internal db becoming completely messed up. I would like to investigate and file a proper bug report or find a fix / workaround, but I don't understand how Amarok does the ripping. When all is working, there's a lame process encoding to a temporary file, which appears in my collection once it's finished. When the process hangs, that lame command is still there, but waiting forever for data on stdin, which seems to come from a third process. That seems to be kio_audiocd, but I don't know whether that's correct and what it's supposed to do. What's going on?

• How can I disable multiple links with jQuery?

  - by Samantha J

  I have the following HTML: <a title="Login" data-href="/MyAccount/Access/Login" data-title="Admin" data-entity="n/a" id="loginLink" class="nav-button dialogLink"><b>Login</b></a> <a title="Register" data-href="/MyAccount/Access/Register" data-title="Admin" data-entity="n/a" id="registerLink" class="nav-button dialogLink"><b>Register</b></a> When a user clicks on the #loginLink or #registerLink I would like to disable the link and call a dialog script. I created the following function: $("#loginLink, #registerLink") .click(function () { $('#loginLink').prop('disabled', true); $('#registerLink').prop('disabled', true); dialog(this); }); It calls the dialog correctly but doesn't disable the links and if I click the buttons more than once it calls up more than one dialog box. Is there something I am doing wrong? I can't see why it would not work.

• Progressing Alfresco workflows through web script

  - by Domchi

  I have an Alfresco document reference; what I'm looking for is a way to access workflow attached to that document and finish it (or progress it to the next transition) through Javascript. Almost every example on the web shows how to start workflow, and from the dashlet I could call task command processor (/alfresco/command/task/end/[/transition]) if I knew the task ID, but how do I do the same thing from server-side web script starting only from the document reference? There must be a way to access workflows from document and manage them programatically.

• Cork Board Solution to tack things up on top or to the side of a monitor

  - by Bela

  I'm trying to find some sort of physical product that would either go on the top or the side of an lcd monitor and give me space to tape/push-pin/post it note things for myself. In my head I am picturing an extra space above your monitor 6 inches tall that lets you tape/push pin things up in front of you. For random notes and things I want to keep track of, having them on the top/side of my monitor would keep the space on my desk itself clear, and they would be closer to my field of vision. Does something like this exist? Do I need to rig up something myself? EDIT This is the closest thing I can find so far http://www.unplggd.com/unplggd/diy-project/reverse-engineer-how-to-feel-up-your-monitor-048251

• How can I use a value from a session variable as part of the group name in signalR

  - by user1844734

  Hi I am trying to set up signalR to distribute messages to web users the problem is that the one site holds different 'areas' and also 'user types'. The Area is decided when the user visits the site by passing a url parameter, this is then stored in a session variable, The 'user type' is by default not logged in then changed when the user logs in to there user type (returned from a webservice) and stored in a User object. My aim was to connect to the hub using signalR when the user visits the site and add the users connectionId to a groupname, using the 'area id' from the session and the 'user type id' from the User object in the context. The problem I am having is that I can obtain the user id but when it comes to the area id signalR cannot access the session. I understand the reasoning behind not allowing the session available in signalR but does any one know if there is a way to enable this or an alternative way that I can gain access to the users area so that I can create these unique groups.
