  • Sphinx PHP search

    - by James
    I'm doing a Sphinx search but turning up some really weird results. Any help is appreciated. So for example if I type "50", I get: 50 Cent 50 Lions 50 Foot Wave, etc. This is great, but when I search "50 Ce", I get: Ryczace Dwudziestki Spisek Bernhard Gal Cowabunga Go-Go And other crazy results. Also when I search for "50 Cent", the correct result is at the top, but then random results below. Any ideas why? PHP code: $query = $_GET['query']; if (!empty($query)) { $sphinx->SetMatchMode(SPH_MATCH_ALL); $sphinx->AddQuery($query, 'artists'); $sphinx->AddQuery($query, 'variations'); $sphinx->SetFilter('name', array(3)); $sphinx->SetLimits(0, 10); $result = $sphinx->RunQueries(); echo '<pre>'; switch ($result) { case false: echo 'Query failed: ' . $sphinx->GetLastError() . "\n"; break; default: if ($sphinx->GetLastWarning()) { echo 'WARNING: ' . $sphinx->GetLastWarning() . "\n"; } if (is_array($result[0]['matches']) && count($result[0]['matches'])) { foreach ($result[0]['matches'] as $value => $info) { $artist = artistDetails($value); echo $artist['name'] . "\n"; } } } } Sphinx Index and Source: source artists { type = mysql sql_host = localhost sql_user = user sql_pass = pass sql_db = db sql_port = 3300 sql_query = \ SELECT \ id, name \ FROM artists; #UNIX_TIMESTAMP(time) #sql_attr_uint = group_id #sql_attr_timestamp = time sql_query_info = SELECT id,name FROM artists WHERE id=$id } index artists { source = artists path = /var/sphinx/artists docinfo = extern charset_type = utf-8 }

  • MVVM Binding Selected RadOutlookBarItem

    - by Christian
    Imagine: [RadOutlookBarItem1] [RadOutlookBarItem2] [RadOutlookBar] [CONTENCONTROL] What i want to achieve is: User selects one of the RadOutlookBarItem's. Item's tag is bound like: Tag="{Binding SelectedControl, Mode=TwoWay}" MVVM Property public string SelectedControl { get { return _showControl; } set { _showControl = value; OnNotifyPropertyChanged("ShowControl"); } } ContentControl has multiple CustomControls and Visibility of those is bound like: <UserControl.Resources> <Converters:BoolVisibilityConverter x:Key="BoolViz"/> </UserControl.Resources> <Grid x:Name="LayoutRoot" Background="White"> <Views:ViewDocumentSearchControl Visibility="{Binding SelectedControl, Converter={StaticResource BoolViz}, ConverterParameter='viewDocumentSearchControl'}"/> <Views:ViewStartControl Visibility="{Binding SelectedControl, Converter={StaticResource BoolViz}, ConverterParameter='viewStartControl'}"/> </Grid> Converter: public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { // here comes the logic part... should return Visibility.Collapsed : Visibility.Visible based on 'object value' value System.Diagnostics.Debugger.Break(); return Visibility.Collapsed; } now, logically the object value is always set to null. So here's it comes to my question: How can i put a value into the SelectedControl Variable for the RadOutlookBarItem's Tag. I mean something like Tag="{Binding SelectedControl, Mode=TwoWay, VALUE='i.e.ControlName'"} So that i can decide, using the Convert Method, whether a specific Control's visibility is either set to collapsed or visible? help's appreciated Christian

  • Lisp Style question label local functions or not?

    - by Andrew Myers
    I was wondering if there is a standard practice regarding the use of labels in Lisp. I've been messing around with a Lisp implementation of the algorithm described in the first answer here http://stackoverflow.com/questions/352203/generating-permutations-lazily My current version uses labels to break out portions of functionality. (defun next-permutation (pmute) (declare (vector pmute)) (let ((len (length pmute))) (if (> len 2) (labels ((get-pivot () (do ((pivot (1- len) (1- pivot))) ((or (= pivot 0) (< (aref pmute (1- pivot)) (aref pmute pivot))) pivot))) (get-swap (pivot) (let ((swp (1- len))) (loop for i from (1- len) downto pivot do (if (or (and (> (aref pmute i) (aref pmute (1- pivot))) (< (aref pmute i) (aref pmute swp))) (< (aref pmute swp) (aref pmute (1- pivot)))) (setf swp i))) swp)) (next (swp pivot) (rotatef (aref pmute (1- pivot)) (aref pmute swp)) (reverse-vector pmute pivot (1- len)))) (let ((piv (get-pivot))) (if (> piv 0) (next (get-swap piv) piv) nil)))))) Since each label is only called once I was wondering if this is considered bad practice since the only reason to do it in this case is for aesthetic reasons. I would argue that the current version with labels is clearer but that may go against common wisdom that I'm not aware of, being new to Lisp.

  • Building Cross Platform app - recommendation

    - by Ben
    Hi, I need to build a fairly simple app but it needs to work on both PC and Mac. It also needs to be redistributable on a disc or usb drive as a standalone desktop app. Initially I thought AIR would be perfect for this (it ticks all the API requirements), but the difficulty is making it distributable, as the app would require the AIR runtime to be installed to run. I came across Shu Player as an option as it seems to be able to package the AIR runtime with the app and do a (silent?) install. However this seems to break the T&C from Adobe (as outlined here) so I'm not sure about the legality. Another option could be Zinc but I haven't tested it so I'm not sure how well it'll fit the bill. What would you recommend or suggest I check out? Any suggestion much appreciated EDIT: There's a few more discussions on mono usage (though no real conclusion): Here and Here EDIT2: Titanium could also fit the bill maybe, will check it out. Any more comments from anyone? Ben

  • New to MVVM - Best practices for seperating Data processing thread and UI Thread?

    - by OffApps Cory
    Good day. I have started messing around with the MVVP pattern, and I am having some problems with UI responsiveness versus data processing. I have a program that tracks packages. Shipment and package entities are persisted in SQL database, and are displayed in a WPF view. Upon initial retrieval of the records, there is a noticeable pause before displaying the new shipments view, and I have not even implemented the code that counts shipments that are overdue/active yet (which will necessitate a tracking check via web service, and a lot of time). I have built this with the Ocean framework, and all appears to be doing well, except when I first started my foray into multi-threading. It broke, and it appeared to break something in Ocean... Here is what I did: Private QueryThread As New System.Threading.Thread(AddressOf GetShipments) Public Sub New() ' Insert code required on object creation below this point. Me.New(ViewManagerService.CreateInstance, ViewModelUIService.CreateInstance) 'Perform initial query of shipments 'QueryThread.Start() GetShipments() Console.WriteLine(Me.Shipments.Count) End Sub Public Sub New(ByVal objIViewManagerService As IViewManagerService, ByVal objIViewModelUIService As IViewModelUIService) MyBase.New(objIViewModelUIService) End Sub Public Sub GetShipments() Dim InitialResults = From shipment In db.Shipment.Include("Packages") _ Select shipment Me.Shipments = New ShipmentsCollection(InitialResults, db) End Sub So I declared a new Thread, assigned it the GetShipments method and instanced it in the default constructor. Ocean freaks out at this, so there must be a better way of doing it. I have not had the chance to figure out the usage of the SQL ORM thing in Ocean so I am using Entity Framework (perhaps one of these days i will look at NHibernate or something too). Any information would be greatly appreciated. I have looked at a number of articles and they all have examples of simple uses. Some have mentioned the Dispatcher, but none really go very far into how it is used. Anyone know any good tutorials? Cory

  • OpenCV Python HoughCircles error

    - by Dan
    Hi, I'm working on a program that detects circular shapes in images. I decided a Hough Transform would be the best, and I found one in the OpenCV library. The problem is that when I try to use it I get an error that I have no idea how to fix. Is OpenCV for Python not fully implemented? Is there a fix to the library I need for the program to work? Here's the code: import cv #cv.NamedWindow("camera", 1) capture = cv.CaptureFromCAM(0) while True: img = cv.QueryFrame(capture) gray = cv.CreateImage(cv.GetSize(img), 8, 1) edges = cv.CreateImage(cv.GetSize(img), 8, 1) cv.CvtColor(img, gray, cv.CV_BGR2GRAY) cv.Canny(gray, edges, 50, 200, 3) cv.Smooth(gray, gray, cv.CV_GAUSSIAN, 9, 9) storage = cv.CreateMat(1, 2, cv.CV_32FC3) #This is the line that throws the error cv.HoughCircles(edges, storage, cv.CV_HOUGH_GRADIENT, 2, gray.height/4, 200, 100) #cv.ShowImage("camera", img) if cv.WaitKey(10) == 27: break And here is the error I'm getting: OpenCV Error: Null pinter () in unknown function, file ..\..\..\..\ocv\openc\src\cxcore\cxdatastructs.cpp, line 408 Traceback (most recent call last): File "ellipse-detect-webcam.py", line 20, in cv.HoughCircles(edges, storage, cv.CV_HOUGH_GRADIENT, 2, gray.height/4, 200, 100) cv.error Thanks in advance for the help.

  • Finding if a Binary Tree is a Binary Search Tree

    - by dharam
    Today I had an interview where I was asked to write a program which takes a Binary Tree and returns true if it is also a Binary Search Tree otherwise false. My Approach1: Perform an inroder traversal and store the elements in O(n) time. Now scan through the array/list of elements and check if element at ith index is greater than element at (i+1)th index. If such a condition is encountered, return false and break out of the loop. (This takes O(n) time). At the end return true. But this gentleman wanted me to provide an efficient solution. I tried but I was unsuccessfult, because to find if it is a BST I have to check each node. Moreover he was pointing me to think over recusrion. My Approach 2: A BT is a BST if for any node N N-left is < N and N-right N , and the INorder successor of left node of N is less than N and the inorder successor of right node of N is greater than N and the left and right subtrees are BSTs. But this is going to be complicated and running time doesn't seem to be good. Please help if you know any optimal solution. Thanks.

  • function to get the file name of an URL

    - by user262325
    Hello everyone I have some source code to get the file name of an url for example: http://www.google.com/a.pdf I hope to get a.pdf because the way to join 2 NSStrings I can get is 'appendString' which only for adding a string at right side, so I planned to check each char one by one from the right side of string 'http://www.google.com/a.pdf', when it reach at the char '/', stop the checking, return string fdp.a , after that I change fdp.a to a.pdf source codes are below -(NSMutableString *) getSubStringAfterH : originalString:(NSString *)s0 { NSInteger i,l; l=[s0 length]; NSMutableString *h=[[NSMutableString alloc] init]; NSMutableString *ttt=[[NSMutableString alloc] init ]; for(i=l-1;i>=0;i--) //check each char one by one from the right side of string 'http://www.google.com/a.pdf', when it reach at the char '/', stop { ttt=[s0 substringWithRange:NSMakeRange(i, 1)]; if([ttt isEqualToString:@"/"]) { break; } else { [h appendString:ttt]; } } [ttt release]; //below are to change the sequence of char in h // txt.edcba -> abcde.txt NSMutableString *h1=[[[NSMutableString alloc] initWithFormat:@""] autorelease]; for (i=[h length]-1;i>=0;i--) { NSMutableString *t1=[[NSMutableString alloc] init ]; t1=[h substringWithRange:NSMakeRange(i, 1)]; [h1 appendString:t1]; [t1 release]; } [h release]; return h1; } h1 can reuturn the coorect string a.pdf, but if it returns to the codes where it was called, after a while system reports 'double free * set a breakpoint in malloc_error_break to debug' I checked a long time and foudn that if I removed the code ttt=[s0 substringWithRange:NSMakeRange(i, 1)]; everything will be Ok (of course getSubStringAfterH can not returns the corrent result I expected.), no error reported. I try to fix the bug a few hours, but still no clue. Welcome any comment Thanks interdev

  • Disco/MapReduce: Using results of previous iteration as input to new iteration

    - by muckabout
    Currently am implementing PageRank on Disco. As an iterative algorithm, the results of one iteration are used as input to the next iteration. I have a large file which represents all the links, with each row representing a page and the values in the row representing the pages to which it links. For Disco, I break this file into N chunks, then run MapReduce for one round. As a result, I get a set of (page, rank) tuples. I'd like to feed this rank to the next iteration. However, now my mapper needs two inputs: the graph file, and the pageranks. I would like to "zip" together the graph file and the page ranks, such that each line represents a page, it's rank, and it's out links. Since this graph file is separated into N chunks, I need to split the pagerank vector into N parallel chunks, and zip the regions of the pagerank vectors to the graph chunks This all seems more complicated than necessary, and as a pretty straightforward operation (with the quintessential mapreduce algorithm), it seems I'm missing something about Disco that could really simplify the approach. Any thoughts?

  • JEE6 Global JNDI Name and Maven Deployment

    - by wobblycogs
    I'm having some problems with the global JNDI names of my EJB resources which is (or at least will) cause my JNDI look ups to fail. The project is being developed on Netbeans and is a standard Maven Web Application. When my application is deployed to GF3.0 the application name is set to something like: com.example_myapp_war_1.0-SNAPSHOT which is all well and good from Netbeans point of view because it ensures the name is unique but it also means all the EJBs get global names such as this: java:global/com.example_myapp_war_1.0-SNAPSHOT/CustomerService This, of course, is going to cause problems because every time the version changes all the global names change (I've tested this by changing the version and the names indeed changed). The name is being generated from the POM file and it's a concatenation of: <groupId>com.example</groupId> <artifactId>myapp</artifactId> <packaging>war</packaging> <version>1.0-SNAPSHOT</version> Up until now I've got away with just injecting all the resources using @EJB but now I need to access the CustomerService EJB from a JSF Converter so I'm doing a JNDI look up like this: try { Context ctx = new InitialContext(); CustomerService customerService = (CustomerService)ctx.lookup( "java:global/com.example_myapp_war_1.0-SNAPSHOT/CustomerService" ); return customerService.get(submittedValue); } catch( Exception e ) { logger.error( "Failed to convert customer.", e ); return null; } which will clearly break when the application is properly released and the module name changes. So, the million dollar question: how can I set the modle name in maven or how do I recover the module name so that I can programatically build the JNDI name at runtile. I've tried setting it in the web.xml file as suggested by that link but it was ignored. I think I'd rather build the name at runtime as that means there is less scope for screw ups when the application is deployed. Many thanks for any help, I've been tearing my hair out all day on this.

  • Django queryset not returning the same values as the generated sql

    - by HRCerqueira
    Hello guys, I have the following queryset: subscribers = User.objects.values('email', 'username').filter( Q(subscription_settings__new_question='i') | Q(subscription_settings__new_question_watched_tags='i', marked_tags__id__in=question.tags.values('id'), tag_selections__reason='good') ).exclude(id=question.author.id) The problem is that when I evaluate the query I get only the values that are filtered by the first Q object (even if I reverse the order of the objects). So lets say that I was expecting the user A, B, C and D, where A and B are filtered by the first Q object and C and D by the second. But the queryset only returns A and B. I used the django debug toolbar to see the query that was actually being executed (and then I used a direct print statement like "print subscriber.query.as_sql()" just to be sure) and then evaluated the query directly using psql (I'm using postgres by the way), and I get the results I expect. Here's the query btw: SELECT "auth_user"."email", "auth_user"."username" FROM "auth_user" LEFT OUTER JOIN "forum_markedtag" ON ("auth_user"."id" = "forum_markedtag"."user_id") INNER JOIN "forum_defaultsubscriptionsetting" ON ("auth_user"."id" = "forum_defaultsubscriptionsetting"."user_id") WHERE ((("forum_markedtag"."reason" = E'good' AND "forum_defaultsubscriptionsetting"."new_question_watched_tags" = E'i' AND "forum_markedtag"."tag_id" IN (SELECT U0."id" FROM "tag" U0 INNER JOIN "question_tags" U1 ON (U0."id" = U1."tag_id") WHERE U1."question_id" = 64 )) OR "forum_defaultsubscriptionsetting"."new_question" = E'i' ) AND NOT ("auth_user"."id" = 10 )) Thanks in advance EDIT: I tried to break the queryset into two, one that uses the first Q object as the filter and another one with the second Q object, and although the second queryset produces the correct sql that returns the correct values when evaluated directly, it still doesn't return nothing when evaluated as a django queryset. heres the alternative code: subscribers = User.objects.values('email', 'username').filter( subscription_settings__new_question='i').exclude(id=question.author.id) subscribers2 = User.objects.values('email', 'username').filter( subscription_settings__new_question_watched_tags='i', marked_tags__id__in=question.tags.values('id'), tag_selections__reason='good').exclude(id=question.author.id)

  • Problem with creation of scheduled task from IIS6 on SR2003

    - by Morten Louw Nielsen
    Hi, I am writing a webapplication using .NET. The webapp creates scheduled tasks using the System.Diagnostics.Process class, calling SCHTASKS.EXE with parameters. I have changed the identity on the app pool, to a specific domain user. The domain-user is local administrator on all the four webservers. From webserver01 I am creating tasks on webserver01 to webserver04. It works perfect for 3-5 days, but then it breaks. It gives me the following errormessage in a messagebox: "The application failed to initialize properly (0xc0000142). Click on OK to terminate the application." If I have the system in the broken state, and I change the identity of the app pool to Domain administrator, it works. As I change it back to my domain-user, it breaks again. If I reboot the server, it works again for the same amount of days, but will break again. It seems like a permission-related problem. I just don't understand why it works sometimes, and sometimes doesn't. I hope someone outthere has seen this problem! Looking forward to hear from you! Kind regards, Morten, Denmark

  • nth ugly number

    - by Anil Katti
    Numbers whose only prime factors are 2, 3 or 5 are called ugly numbers. Example: 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, ... 1 can be considered as 2^0. I am working on finding nth ugly number. Note that these numbers are extremely sparsely distributed as n gets large. I wrote a trivial program that computes if a given number is ugly or not. For n 500 - it became super slow. I tried using memoization - observation: ugly_number * 2, ugly_number * 3, ugly_number * 5 are all ugly. Even with that it is slow. I tried using some properties of log - since that will reduce this problem from multiplication to addition - but, not much luck yet. Thought of sharing this with you all. Any interesting ideas? Using a concept similar to "Sieve of Eratosthenes" (thanks Anon) for (int i(2), uglyCount(0); ; i++) { if (i % 2 == 0) continue; if (i % 3 == 0) continue; if (i % 5 == 0) continue; uglyCount++; if (uglyCount == n - 1) break; } i is the nth ugly number. Even this is pretty slow. I am trying to find 1500th ugly number.

  • Best way to sanitize content with PHP?

    - by Jens Törnell
    Which is the best way to "sanitize" content? An example... Example - Before sanitize: Morbi mollis ante vitae massa suscipit a tempus est pellentesque. Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Nulla mattis iaculis consectetur. Morbi mollis ante vitae est pellentesque. Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Nulla mattis iaculis consectetur. Example - After sanitize: <p>Morbi mollis ante vitae massa suscipit a tempus est pellentesque. Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Nulla mattis iaculis consectetur.</p> <p>Morbi mollis ante vitae est pellentesque. Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Nulla mattis iaculis consectetur.</p> What it should do It should add p-tags instead of line break like. It should remove empty space like tripple spaces It should remove double line breaks. It should remove tabs. It should remove line breaks and spaces before the content if any. It should remove line breaks and spaces after the content if any. Right know I use the str_replace function and it should be a better solution for this? I want the function to look like this: function sanitize($content) { // Do the magic! return $content; }

  • dll's loaded through reflection - Phantom Bug

    - by Seattle Leonard
    Ok, I got a strange one here and I want to know if any of you have ever run accross anything like it. So I've got this web app that loads up a bunch of dll's through reflection. Basically it looks for Types that are derived from certain abstract types and adds them to the list of things it can make. Here's the weird part. While developing there is never a problem. When installing it, there is never a problem to start with. Then, at a seemingly random time, the application breaks while trying to find all the types. I've had 2 sites sitting side by side and one worked while the other did not, and they were configured exactly(and I mean exactly) the same. IISRESET's never helped, but this did: I simply moved all the dll's out of the bin directory then moved them back. That's right I just moved them out of the bin directory then put them right back where they came from and everything worked fine. Any ideas? Got some more info When the site is working I notice this behavior: After IISRESET it still works, but recycling the app pool will cause it to break. When the site is broken: Neiter IISRESET nor recycling the app pool fixes it, but moving a single dll out then back in fixes it.

  • How to refactor this Javascript anonymous function?

    - by HeavyWave
    We have this anonymous function in our code, which is part of the jQuery's Ajax object parameters and which uses some variables from the function it is called from. this.invoke = function(method, data, callback, error, bare) { $.ajax({ success: function(res) { if (!callback) return; var result = ""; if (res != null && res.length != 0) var result = JSON2.parse(res); if (bare) { callback(result); return; } for (var property in result) { callback(result[property]); break; } } }); } I have omitted the extra code, but you get the idea. The code works perfectly fine, but it leaks 4 Kbs on each call in IE, so I want to refactor it to turn the anonymous function into a named one, like this.onSuccess = function(res) { .. }. The problem is that this function uses variables from this.invoke(..), so I cannot just take it outside of its body. How do I correctly refactor this code, so that it does not use anonymous functions and parent function variables?

  • AS3 "Loader" progress immediately goes to 100%

    - by Bart van Heukelom
    If you go to http://moederdagontbijtplacemat.nl/ you will see a progress bar. The application is loading a fairly large SWF from the server using the Loader class. Strangely enough, the progress bar immediately goes to 100% (but the loading still takes a while after that). The code is below, but you'll see it's basically too simple to break. It has worked when the application was on a different server, so I though maybe the new server wasn't sending the size of the large SWF in the http headers. Firebug does show a progress bar though, so that is not the case, the information should be available. It also works when I run the loader swf locally and change the URL (new URLRequest("Placemat.swf")) to the absolute URL of Placemat.swf on the server. var l:Loader = new Loader(); addChild(l); l.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, function(e:ProgressEvent) { s.setProgress(e.bytesLoaded/e.bytesTotal); trace(Math.round(100 * e.bytesLoaded/e.bytesTotal), "%"); }); l.contentLoaderInfo.addEventListener(Event.COMPLETE, function() { removeChild(s); }); l.load(new URLRequest("Placemat.swf"));

  • Spikes in Socket Performance

    - by Harun Prasad
    We are facing random spikes in high throughput transaction processing system using sockets for IPC. Below is the setup used for the run: The client opens and closes new connection for every transaction, and there are 4 exchanges between the server and the client. We have disabled the TIME_WAIT, by setting the socket linger (SO_LINGER) option via getsockopt as we thought that the spikes were caused due to the sockets waiting in TIME_WAIT. There is no processing done for the transaction. Only messages are passed. OS used Centos 5.4 The average round trip time is around 3 milli seconds, but some times the round trip time ranges from 100 milli seconds to couple of seconds. Steps used for Execution and Measurement and output Starting the server $ python sockServerLinger.py /dev/null & Starting the client to post 1 million transactions to the server. And logs the time for a transaction in the client.log file. $ python sockClient.py 1000000 client.log Once the execution finishes the following command will show the execution time greater than 100 milliseconds in the format <line_number>:<execution_time>. $ grep -n "0.[1-9]" client.log | less Below is the example code for Server and Client.

Height="300" Width="300"> <Grid> <Label> `_Twas brillig, and the slithy toves did gyre and gimble in the wabe: all mimsy were the borogoves, and the mome raths outgrabe.</Label> </Grid> </Window> Am I doing something wrong? Taking other controls is unfortunately not a good option, since I need support of access keys. Replacing the Label with a TextBlock (having TextWrapping="Wrap"), and adjusting its control template to recognize access keys would be perhaps a solution, but isn't it an overkill? Edit: having a non-standard style for label will break skinning, so I would like to avoid it if possible.

  • why does Integrated Windows Authentication fail when clients access off the network

    - by Bryan
    My background is not with web applications so this problem is hard for me to explain easily. First I'll try to describe the setup. Client setup:-Only browser that is effected is IE 6-8 (Firefox, chrome, opera, and safari all work fine) -A user will try to access our web application from a company laptop that is not connected to our network. -This machine will be a member of our workgroup and have the company DNS listed as a trusted intranet site. (to which the application in question would be a member) -The security logon mode is set to Automatic Logon only in intranet zone only, and IWA authentication is enabled on the clients browser.Server setup:-Windows server 2003 fp2-The application will first redirect to an Authorization asp page which has anonymous access disabled and IWA enabled in IIS.what should happen is that, since the client is not currently on the network, when this page is called it should prompt the user for network credentials. But with IE, instead of prompting, the user gets a page cannot be displayed error because the IIS manager is denying access to the asp page. If the company DNS is removed from the trusted intranet site list then it prompts correctly but disables single sign on the next time that computer is connected to the network or vpn. My assumption is that since IE uses IWA and the site is listed as an internal site, when no network is found IE just sends nulls to the server attempting to authenticate which is swiftly punted back. Other browsers do not have security zones so when network credentials are not present the server prompts for them. Is there a way to get around this so that our clients can keep the company DNS in the intranet zone but still have the server prompt for credentials when not on the network? Any attempt to allow for anonymous access on the asp page, as far as I know, will cause AUTH_USER to return null and again break SSO. I realize this is slightly rambling so I will do my best to clarify and questions you guys might have. Thanks in advance.

  • Default class for SQLAlchemy single table inheritance

    - by eclaird
    I've set up a single table inheritance, but I need a "default" class to use when an unknown polymorphic identity is encountered. The database is not in my control and so the data can be pretty much anything. A working example setup: import sqlalchemy as sa from sqlalchemy import orm engine = sa.create_engine('sqlite://') metadata = sa.MetaData(bind=engine) table = sa.Table('example_types', metadata, sa.Column('id', sa.Integer, primary_key=True), sa.Column('type', sa.Integer), ) metadata.create_all() class BaseType(object): pass class TypeA(BaseType): pass class TypeB(BaseType): pass base_mapper = orm.mapper(BaseType, table, polymorphic_on=table.c.type, polymorphic_identity=None, ) orm.mapper(TypeA, inherits=base_mapper, polymorphic_identity='A', ) orm.mapper(TypeB, inherits=base_mapper, polymorphic_identity='B', ) Session = orm.sessionmaker(autocommit=False, autoflush=False) session = Session() Now, if I insert a new unmapped identity... engine.execute('INSERT INTO EXAMPLE_TYPES (TYPE) VALUES (\'C\')') session.query(BaseType).first() ...things break. Traceback (most recent call last): File "<stdin>", line 1, in <module> File ".../SQLAlchemy-0.6.5-py2.6.egg/sqlalchemy/orm/query.py", line 1619, in first ret = list(self[0:1]) File ".../SQLAlchemy-0.6.5-py2.6.egg/sqlalchemy/orm/query.py", line 1528, in __getitem__ return list(res) File ".../SQLAlchemy-0.6.5-py2.6.egg/sqlalchemy/orm/query.py", line 1797, in instances rows = [process[0](row, None) for row in fetch] File ".../SQLAlchemy-0.6.5-py2.6.egg/sqlalchemy/orm/mapper.py", line 2179, in _instance _instance = polymorphic_instances[discriminator] File ".../SQLAlchemy-0.6.5-py2.6.egg/sqlalchemy/util.py", line 83, in __missing__ self[key] = val = self.creator(key) File ".../SQLAlchemy-0.6.5-py2.6.egg/sqlalchemy/orm/mapper.py", line 2341, in configure_subclass_mapper discriminator) AssertionError: No such polymorphic_identity u'C' is defined What I expected: >>> result = session.query(BaseType).first() >>> result <BaseType object at 0x1c8db70> >>> result.type u'C' I think this used to work with some older version of SQLAlchemy, but I haven't been keeping up with the development lately. Any pointers on how to accomplish this?

  • When does a PHP <5.3.0 daemon script receive signals?

    - by MidnightLightning
    I've got a PHP script in the works that is a job worker; its main task is to check a database table for new jobs, and if there are any, to act on them. But jobs will be coming in in bursts, with long gaps in between, so I devised a sleep cycle like: while(true) { if ($jobs = get_new_jobs()) { // Act upon the jobs } else { // No new jobs now sleep(30); } } Good, but in some cases that means there might be a 30 second lag before a new job is acted upon. Since this is a daemon script, I figured I'd try the pcntl_signal hook to catch a SIGUSR1 signal to nudge the script to wake up, like: $_isAwake = true; function user_sig($signo) { global $_isAwake; daemon_log("Caught SIGUSR1"); $_isAwake = true; } pcntl_signal(SIGUSR1, 'user_sig'); while(true) { if ($jobs = get_new_jobs()) { // Act upon the jobs } else { // No new jobs now daemon_log("No new jobs, sleeping..."); $_isAwake = false; $ts = time(); while(time() < $ts+30) { sleep(1); if ($_isAwake) break; // Did a signal happen while we were sleeping? If so, stop sleeping } $_isAwake = true; } } I broke the sleep(30) up into smaller sleep bits, in case a signal doesn't interrupt a sleep() command, thinking that this would cause at most a one-second delay, but in the log file, I'm seeing that the SIGUSR1 isn't being caught until after the full 30 seconds has passed (and maybe the outer while loop resets). I found the pcntl_signal_dispatch command, but that's only for PHP 5.3 and higher. If I were using that version, I could stick a call to that command before the if ($_isAwake) call, but as it currently stands I'm on 5.2.13. On what sort of situations is the signals queue interpreted in PHP versions without the means to explicitly call the queue parsing? Could I put in some other useless command in that sleep loop that would trigger a signal queue parse within there?

  • Load testing multipart form

    - by JacobM
    I'm trying to load-test a Rails application using JMeter. A critical part of the application involves a form that includes both text inputs and file uploads. It works fine in a browser, but when I try to post that page in JMeter, Rails is saving all of the parts of the multipart form as temp files, which causes things to break when it's looking for a string and gets a tempfile instead. It appears that the difference is that, from a browser, the piece of the multipart request that contains a text input looks like this: -----------------------------7d93b4186074c Content-Disposition: form-data; name="field_name" test -----------------------------7d93b4186074c while from JMeter it looks like this: -----------------------------7d159c1302d0y0 Content-Disposition: form-data; name="field_name" Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 8bit test -----------------------------7d159c1302d0y0 So apparently Rails sees the former and interprets it as a plain text value and treats it as a string, but sees the latter and saves it to a temp file. I have not been able to find a setting to convince JMeter not to send the additional headers in the multipart form for non-file fields. Is there a way to convince Rails to ignore those headers and treat the text/plain text as strings instead of text files? Or a quick way to put a filter in front of my controller that will strip the extra headers? Alternately, is there a better tool to load-test a Rails application that includes file upload?
