  • Webrick transparent proxy

    - by zzeroo
    Hi there, I've a absolute simple proxy running. require 'webrick' require 'webrick/httpproxy' s = WEBrick::HTTPProxyServer.new(:Port => 8080, :RequestCallback => Proc.new{|req,res| puts req.request_line, req.raw_header}) # Shutdown functionality trap("INT"){s.shutdown} # run the beast s.start This should in my mind not influence the communication in any way. But some sites doesn't work any more. Specially http://lastfm.de 's embedded flash players doesn't work. The header looks link: - -> http://ext.last.fm/2.0/?api%5Fsig=aa3e9ac9edf46ceb9a673cb76e61fef4&flashresponse=true&y=1269686332&streaming=true&playlistURL=lastfm%3A%2F%2Fplaylist%2Ftrack%2F42620245&fod=true&sk=ee93ae4f438767bf0183d26478610732&lang=de&api%5Fkey=da6ae1e99462ee22e81ac91ed39b43a4&method=playlist%2Efetch GET http://play.last.fm/preview/118270350.mp3 HTTP/1.1 Host: play.last.fm User-Agent: Mozilla/5.0 (X11; U; Linux i686; de; rv:1.9.2) Gecko/20100308 Ubuntu/10.04 (lucid) Firefox/3.6 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: de,en-us;q=0.7,en;q=0.3 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Proxy-Connection: keep-alive Cookie: AnonWSSession=ee93ae4f438767bf0183d26478610732; AnonSession=cb8096e3b0d8ec9f4ffd6497a6d052d9-12bb36d49132e492bb309324d8a4100fc422b3be9c3add15ee90eae3190db5fc localhost - - [27/Mar/2010:11:38:52 CET] "GET http://www.lastfm.de/log/flashclient/minor/Track_Loading_Fail/Buffering_Timeout HTTP/1.1" 404 7593 - -> http://www.lastfm.de/log/flashclient/minor/Track_Loading_Fail/Buffering_Timeout localhost - - [27/Mar/2010:11:38:52 CET] "GET http://play.last.fm/preview/118270350.mp3 HTTP/1.1" 302 0 I nead some hints why or what the communication disturb.

  • WCF Certificates without Certificate Store

    - by Kane
    My team is developing a number of WPF plug-ins for a 3rd party thick client application. The WPF plug-ins use WCF to consume web services published by a number of TIBCO services. The thick client application maintains a separate central data store and uses a proprietary API to access the data store. The thick client and WPF plug-ins are due to be deployed onto 10,000 workstations. Our customer wants to keep the certificate used by the thick client in the central data store so that they don't need to worry about re-issuing the certificate (current re-issue cycle takes about 3 months) and also have the opportunity to authorise the use of the certificate. The proposed architecture offers a form of shared secret / authentication between the central data store and the TIBCO services. Whilst I don’t necessarily agree with the proposed architecture our team is not able to change it and must work with what’s been provided. Basically our client wants us to build into our WPF plug-ins a mechanism which retrieves the certificate from the central data store (which will be allowed or denied based on roles in that data store) into memory then use the certificate for creating the SSL connection to the TIBCO services. No use of the local machine's certificate store is allowed and the in memory version is to be discarded at the end of each session. So the question is does anyone know if it is possible to pass an in-memory certificate to a WCF (.NET 3.5) service for SSL transport level encryption? Note: I had asked a similar question (here) but have since deleted it and re-asked it with more information.

  • I'm using spring, hibernate and mysql. How can I let my app create the table automatically.

    - by Yousui
    Hi guys, I'm using spring, all my annotated entity class information are put in the ApplicationContext.xml.

  • VMWare steals IP addresses [closed]

    - by Ishan Amin
    I'm having a peculiar problem, that I think I have narrowed down to VMware. For the past one year, every once in a while we lose internet connection and not all users (about 10 users) go down at the same time, its usually one-by-one. First someone will call me and say "Internet is down" and then we would go reset the router and modem and switch and it would be working again for a while, then go down again without any pattern or replicatable sequence. We'd go repeat the steps again to get everyone in the office running again. We called our Internet Service Provider and they constantly say, We see your modem and we see your router and from thier end everything is OK. we replaced our router and switch and modem, twice! Last friday, it dawned upon me, that everytime we turn on a VMware machine, this sequence of taking everyone down starts, which also explains the message that my users get for "IP Conflict Found" So we do alot of VMware testing and lo and behold, it takes my Internet down. My Yahoo and Gtalk would continue working but www is down when the VMware machines are started. I do use bridged networking to all the VMware machines, but I dont know what else to set it at. now, sorry for this long rambling but anyone have any clue on how to stop this? thanks IA

  • Dividing sections inside an omp parallel for : OpenMP

    - by Sayan Ghosh
    Hi, I have a situation like: #pragma omp parallel for private(i, j, k, val, p, l) for (i = 0; i < num1; i++) { for (j = 0; j < num2; j++) { for (k = 0; k < num3; k++) { val = m[i + j*somenum + k*2] if (val != 0) for (l = start; l <= end; l++) { someFunctionThatWritesIntoGlobalArray((i + l), j, k, (someFunctionThatGetsValueFromAnotherArray((i + l), j, k) * val)); } } } for (p = 0; p < num4; p++) { m[p] = 0; } } Thanks for reading, phew! Well I am noticing a very minor difference in the results (0.999967[omp] against 1[serial]), when I use the above (which is 3 times faster) against the serial implementation. Now I know I am doing a mistake here...especially the connection between loops is evident. Is it possible to parallelize this using omp sections? I tried some options like making shared(p) {doing this, I got correct values, as in the serial form}, but there was no speedup then. Any general advice on handling openmp pragmas over a slew of for loops would also be great for me!

  • Using singleton instead of a global static instance

    - by Farstucker
    I ran into a problem today and a friend recommended I use a global static instance or more elegantly a singleton pattern. I spent a few hours reading about singletons but a few things still escape me. Background: What Im trying to accomplish is creating an instance of an API and use this one instance in all my classes (as opposed to making a new connection, etc). There seems to be about 100 ways of creating a singleton but with some help from yoda I found some thread safe examples. ..so given the following code: public sealed class Singleton { public static Singleton Instance { get; private set; } private Singleton() { APIClass api = new APIClass(); //Can this be done? } static Singleton() { Instance = new Singleton(); } } How/Where would you instantiate the this new class and how should it be called from a separate class? EDIT: I realize the Singleton class can be called with something like Singleton obj1 = Singleton.Instance(); but would I be able to access the methods within the APIs Class (ie. obj1.Start)? (not that I need to, just asking) EDIT #2: I might have been a bit premature in checking the answer but I do have one small thing that is still causing me problems. The API is launching just fine, unfortunately Im able to launch two instances? New Code public sealed class SingletonAPI { public static SingletonAPI Instance { get; private set; } private SingletonAPI() {} static SingletonAPI() { Instance = new SingletonAPI(); } // API method: public void Start() { API myAPI = new API();} } but if I try to do something like this... SingletonAPI api = SingletonAPI.Instance; api.Start(); SingletonAPI api2 = SingletonAPI.Instance; // This was just for testing. api2.Start(); I get an error saying that I cannot start more than one instance.

  • Duplicate entries on mysql on insert using doctrine

    - by Nikos Galis
    Hi all! I am facing a very weird problem with mysql and doctrine [with help of codeIgniter]. I am trying to make a simple migration script taking all records from one table and after a little process, saving them to another. However, on my laptop [running windows and wamp] I get double numbers of the original table records to have been copied to the destination table. In my colleagues' laptops, everything works fine! We are all using mysql 5.0.86 [plus windows plus wamp]. Here is the code : function buggy_function(){ $this->db(); //get db connection $q = Doctrine_Query::create()->from('Oldtable r'); $oldrecords = $q->fetchArray(); $count = 0; foreach ($oldrecords as $oldrecord){ $newrecord = new NewTableClass(); $newrecord->password = md5($oldrecord['password']); $newrecord->save(); echo $newrecord->id. ' Id -> saved.' } } Simple as that! I have 39 records on the Old table and I am getting 78 records in the new table, which are exactly the same records, except from the unique primary key. It seems as if the script runs twice. But the output of the script is the following : 1 Id -> saved. 2 Id -> saved. ... ... 39 Id -> saved. Do you have any idea why this is happening? Any known bug for mysql? Thank you in advanced!'

  • Save email as draft in php

    - by Yorian
    Hello, The past few days I've been trying to find out how I can save emails as drafts using php. I've created an emailaddress that uses imap (and resides on the same server). What I would like to do is to use php to create an email and store it in the drafts folder. These emails would then be recognized by the email client (ms office outlook in this case) so they can be editted and send from the email client. I've found some interesting information about the imap functions from php, they let you send mail, but I can't really figure out how to store them in the drafts folder (to which I have write access). I can actually find and read the emails, I save as drafts in my email client, using my ftp connection. However they make use of UID and message-ID's and such which I don't understand where they come from. My questions: - how could I create email drafts - How does a new UID or message-ID get created, and how would I use them for my email-draft file? Help is much appreciated, thanks. Yorian

  • Error Log states that I have MySQL connect error, yet script runs fine

    - by rob - not a robber
    Hello All, First, thanks for all the help I've received so far from StackOverflow. I've learned much. Once again, I'm posing a rudimentary question that I've searched on, but cannot find the exact answer to. Here or on PHP.net. It's sort of like what this guy asked, but not exactly: http://stackoverflow.com/questions/288603/mysql-throwing-query-error-yet-finishing-query-just-fine-why So, I saw my errorlog ballooning up when I checked my site directory and opened to notice that a bunch of errors have been recorded since I wrote this new Admin area. I know something is obviously awry with my scripting for the error to be thrown, but the weird thing is, the script actually runs through and pulls all the data I need without breaking. The log contains: PHP Warning: mysql_query() [function.mysql-query]: Access denied for user 'someuser'@'localhost' (using password: NO) in /home/mysite/adminconsole.php on line 15 I don't get that because that very line is where I setup my connection... the exact same way I do it everywhere else on the site with no problem. After that error, I have these thrown at the same time [09-Apr-2010 08:44:18] PHP Warning: mysql_query() [function.mysql-query]: A link to the server could not be established in /home/mysite/adminconsole.php on line 15 [09-Apr-2010 08:44:18] PHP Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/mysite/adminconsole.php on line 16 From what I read in the other guys thread, the problem is the contents of the query maybe? Maybe my query is malformed? Thanks so much for any guidance you can provide. -Rob

  • How to display a subview loaded from a separate NIB file

    - by Marcus Netter
    I'm developing a Cocoa desktop application that uses a source list in the style of iTunes: different elements in the source list cause the main content area to display different views. The content area is entirely filled with a (vertical) NSSplitView; on the left is an NSOutlineView source list. When the user selects an item on the left, the relevant view appears on the right side of the splitter. I can make it work well enough by putting everything in one NIB file and putting a borderless NSTabView to the right of the splitter; to switch views, I just have to change the selected tab. But putting all the views in one NIB is bad practice, so I'm trying to move each of the subviews into their own NIB files. I have a pretty good idea of most of this process — I've created an NSViewController subclass for each of these views (EntityDetailViewController, GroupDetailViewController, and so on), set the File's Owner of each new NIB to the relevant controller class, set the view connection in each NIB, and reworked the bindings. What I don't know is how to actually change which subview is being shown on screen. I've tried using the default generic NSView on the right side and sending it addSubview: messages; I've tried connecting to it as the first subview and calling NSView *newSubview = /* get subview from the new subview controller */ [[subview superview] replaceSubview:subview with:newSubview]; [self setSubview:newSubview]; But everything just leaves the space blank. How do I display a subview loaded from a separate NIB?

  • Can SOTI's MobiControl software interfere with an ASP.Net web service?

    - by MusiGenesis
    We have a set of WinMo (5.0) devices running a .NET CF application that talks to an ASP.Net web service running on a server. The devices connect to the network either via ActiveSync through a networked PC or directly to the network via an Ethernet dongle. In our development environment, the communication between devices and web service is 100% reliable. In our production environment, the communications are failing erratically and unpredictably. Sometimes calls to the web service (even to a simple test call that just returns a boolean) begin failing every time on a particular device, with the error message "Could not establish connection to network." This is usually fixed by flip-flopping the selected combo box values on the SETTINGS | NETWORKS screen. Sometimes calls on a particular device begin failing with a generic "WebException" message. The fix for this problem (so far) is either to reset the device (i.e. reinstall the OS) or else it just can't be fixed on some devices. To the best of our knowledge, everything about the DEV and PROD systems are the same (same server and device specs). The most obvious difference to us is that the PROD devices are all controlled by SOTI's MobiControl (which is server-side software that communicates with a SOTI client application installed on each device), whereas our DEV environment does not have SOTI installed anywhere (obviously we should have it there as well - long story). Does anybody have any experience with SOTI MobiControl and/or know of any documented problems where SOTI interferes with other communication mechanisms on a device?

  • fsockopen soap request

    - by gosom
    I am trying to send a SOAP message to a service using php. I want to do it with fsockopen, here's is the code : <?php $fp = @fsockopen("ssl://xmlpropp.worldspan.com", 443, $errno, $errstr); if (!is_resource($fp)) { die('fsockopen call failed with error number ' . $errno . '.' . $errstr); } $soap_out = "POST /xmlts HTTP/1.1\r\n"; $soap_out .= "Host: 212.127.18.11:8800\r\n"; //$soap_out .= "User-Agent: MySOAPisOKGuys \r\n"; $soap_out .= "Content-Type: text/xml; charset='utf-8'\r\n"; $soap_out .= "Content-Length: 999\r\n\r\n"; $soap_put .= "Connection: close\r\n"; $soap_out .= "SOAPAction:\r\n"; $soap_out .= ' Worldspan This is a test '; if(!fputs($fp, $soap_out, strlen($soap_out))) echo "could not write"; echo "<xmp>".$soap_out."</xmp>"; echo "--------------------<br>"; while (!feof($fp)) { $soap_in .= fgets($fp, 100); } echo "<xmp>$soap_in</xmp>"; fclose($fp); echo "ok"; the above code just hangs . if i remove the while it types ok, so i suppose the problem is at $soap_in .= fgets($fp, 100) Any ideas of what is happening

  • Codeigniter: Base_url doesn't seem to be working

    - by Dwayne
    I have developed a simple site that fetches tweets from the Twitter public timeline, caches them for 60 seconds and so on. I have recently moved hosts from Hostgator to Mediatemple and my site was previously working fine on Hostgator. My application doesn't use a database connection, nor does it use any form of flat-file database either. Tweets are cached in an XML file stored in the root directory, not that most of that is important. The url helper is being included as can be seen below (this is my helpers line from autoload.php): $autoload['helper'] = array('url'); I have also removed my index.php file from the URL using .htaccess directives and once again this was previously working on Hostgator (see my .htaccess code below): RewriteEngine On RewriteRule ^(application) - [F,L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule .* index.php/$0 [PT,L] In my home.php view file which is in the views folder inside of application, I am using the function base_url() which was previously working on Hostgator inside of my view files and appending it a base href value in my header: <base href="<?php echo base_url(); ?>" /> Here is what my base_url value looks like in the config.php file: $config['base_url'] = "http://threetune.com/"; Although what appears to be happening is that the base_url is not to be seen at all. It doesn't appear to be echoing out the value of base_url as it appears to be empty for some reason. What makes things weirder is that I have a link in another view file called 'fetch.php' and for some reason it appears to be stripping out the value (XSS filtering is off): <a href="threetune/show"><img src="assets/images/cookie.jpg" /></a> The threetune/show part is not to be seen and I only see an empty href value like this <a href=""><img src="assets/images/cookie.jpg" /></a> Can anyone possibly see anything wrong that I may have done, some kind of Mediatemple server limitation or PHP.ini flag that needs to be set? Thank you and I hope I was descriptive enough.

  • SQL Server 2008 alternative for SQL-DMO

    - by alexdelpiero
    Hi! I previously was using SQL-DMO to automatically generate scripts from the database. Now I upgraded to SQL Server 2008 and I don’t want to use this feature anymore since Microsoft will be dropping this feature off. Is there any other alternative I can use to connect to a server and generate scripts automatically from a database? Any answer is welcome. Thanks in advance. This is the procedure i was previously using: CREATE PROC GenerateSP ( @server varchar(30) = null, @uname varchar(30) = null, @pwd varchar(30) = null, @dbname varchar(30) = null, @filename varchar(200) = 'c:\script.sql' ) AS DECLARE @object int DECLARE @hr int DECLARE @return varchar(200) DECLARE @exec_str varchar(2000) DECLARE @spname sysname SET NOCOUNT ON -- Sets the server to the local server IF @server is NULL SELECT @server = @@servername -- Sets the database to the current database IF @dbname is NULL SELECT @dbname = db_name() -- Sets the username to the current user name IF @uname is NULL SELECT @uname = SYSTEM_USER -- Create an object that points to the SQL Server EXEC @hr = sp_OACreate 'SQLDMO.SQLServer', @object OUT IF @hr <> 0 BEGIN PRINT 'error create SQLOLE.SQLServer' RETURN END -- Connect to the SQL Server IF @pwd is NULL BEGIN EXEC @hr = sp_OAMethod @object, 'Connect', NULL, @server, @uname IF @hr <> 0 BEGIN PRINT 'error Connect' RETURN END END ELSE BEGIN EXEC @hr = sp_OAMethod @object, 'Connect', NULL, @server, @uname, @pwd IF @hr <> 0 BEGIN PRINT 'error Connect' RETURN END END --Verify the connection EXEC @hr = sp_OAMethod @object, 'VerifyConnection', @return OUT IF @hr <> 0 BEGIN PRINT 'error VerifyConnection' RETURN END SET @exec_str = 'DECLARE script_cursor CURSOR FOR SELECT name FROM ' + @dbname + '..sysobjects WHERE type = ''P'' ORDER BY Name' EXEC (@exec_str) OPEN script_cursor FETCH NEXT FROM script_cursor INTO @spname WHILE (@@fetch_status <> -1) BEGIN SET @exec_str = 'Databases("'+ @dbname +'").StoredProcedures("'+RTRIM(UPPER(@spname))+'").Script(74077,"'+ @filename +'")' EXEC @hr = sp_OAMethod @object, @exec_str, @return OUT IF @hr <> 0 BEGIN PRINT 'error Script' RETURN END FETCH NEXT FROM script_cursor INTO @spname END CLOSE script_cursor DEALLOCATE script_cursor -- Destroy the object EXEC @hr = sp_OADestroy @object IF @hr <> 0 BEGIN PRINT 'error destroy object' RETURN END GO

  • Hibernate fails with NullPointerException in EntityTuplizerFactory.constructTuplizer? Why?

    - by Subtwo
    I have a problem when I try to instantiate Hibernate and connect with a MySQL database (see error message below). Curiously enough the connection works fine using the exact same hibernate.cfg.xml file when running Junit tests but it refuses to work when run from Tomcat... I am starting to run out of ideas.

  • What is the suggested approach to Syncing/Backing up/Restoring from SQL Server 2008 to SQL Server 20

    - by Eoin Campbell
    I only have SQL Server 2008 (Dev Edition) on my development machine I only have SQL Server 2005 available with my hosting company (and I don't have direct connection access to this database) I'm just wondering what the best approach is for: Getting the initlal DB Structure & Data into production. And keeping any structural changes/data changes in sync in future. As far as I can see... Replication - not an option cos I can't connect to the production DB. Restoring a backup - not an option because as far as I can see, you cannot export a DB from 2008 that is restorable in 2005 (even with the 2008 DB set in 2005 compatibility mode) and it wouldn't make sense to be restoring production over the top of my dev version anyway. Dump all the scripts from my 2008 Database, Revert my Dev to machine from 2008 - 2005, and recreate the database from the scripts, then just use backup & restore to get the initial DB into production, then run scripts through the web panel from that point onwards Dump all the scripts from my 2008 Database and generate the entire 2005 db from scripts in production. then run scripts through the web panel from that point onwards With the last 2 options, I'd probably need to script all the data inserts as well using some tool (which I presume exists on the web) Are there any other possibile solutions that I'm not considering.

  • change custom mapping - sharp architecture/ fluent nhibernate

    I am using the sharp architecture which also deploys FNH. The db schema sql code is generated during the testing like this: [TestFixture] [Category("DB Tests")] public class MappingIntegrationTests { [SetUp] public virtual void SetUp() { string[] mappingAssemblies = RepositoryTestsHelper.GetMappingAssemblies(); configuration = NHibernateSession.Init( new SimpleSessionStorage(), mappingAssemblies, new AutoPersistenceModelGenerator().Generate(), "../../../../app/XXX.Web/NHibernate.config"); } [TearDown] public virtual void TearDown() { NHibernateSession.CloseAllSessions(); NHibernateSession.Reset(); } [Test] public void CanConfirmDatabaseMatchesMappings() { var allClassMetadata = NHibernateSession.GetDefaultSessionFactory().GetAllClassMetadata(); foreach (var entry in allClassMetadata) { NHibernateSession.Current.CreateCriteria(entry.Value.GetMappedClass(EntityMode.Poco)) .SetMaxResults(0).List(); } } /// <summary> /// Generates and outputs the database schema SQL to the console /// </summary> [Test] public void CanGenerateDatabaseSchema() { System.IO.TextWriter writeFile = new StreamWriter(@"d:/XXXSqlCreate.sql"); var session = NHibernateSession.GetDefaultSessionFactory().OpenSession(); new SchemaExport(configuration).Execute(true, false, false, session.Connection, writeFile); } private Configuration configuration; } I am trying to use: using FluentNHibernate.Automapping; using xxx.Core; using SharpArch.Data.NHibernate.FluentNHibernate; using FluentNHibernate.Automapping.Alterations; namespace xxx.Data.NHibernateMaps { public class x : IAutoMappingOverride<x> { public void Override(AutoMapping<Tx> mapping) { mapping.Map(x => x.text, "text").CustomSqlType("varchar(max)"); mapping.Map(x => x.url, "url").CustomSqlType("varchar(max)"); } } } To change the standard mapping of strings from NVARCHAR(255) to varchar(max). This is not picked up during the sql schema generation. I also tried: mapping.Map(x = x.text, "text").Length(100000); Any ideas? Thanks. Christian

  • How to check for mutual existence of Fields in same table in Two columns

    - by ranabra
    I tried using "Exist" and "IN". Not only did I not succeed, it didn't seem as an efficient solution. Here is a simplified example: TblMyTable WorkerUserName  -  WorkerDegree  -  ManagerUserName  -  ManagerDegree I need a query where there is a mutual connection / existence. What I mean is only where the worker, ex. "John" has a manager named "Mary", and where Mary the manager has a worker named "John". John the worker can have several managers and Mary the manager can have several workers. So the result will be (the order doesn't matter) ideally in one line: John - BSc  --  Mary - M.A. or Mary - M.A.  --  John - BSc The punchline is it's only one table. it is not really managers and workers, this is just a simplification of the situation. In the real situation both are equal, in a Table of names of users working with other users. Database is SQL 2005. Many thanx in advance

  • Mysterious socket / HttpWebRequest timeouts

    - by Daniel Mošmondor
    I have a great app for capturing shoutcast streams :-) . So far, it worked with a charm on dozens of machines, and never exhibited behaviour I found now, which is ultimately very strange. I use HttpWebRequest to connect to the shoutcast server and when I connect two streams, everything's OK. When I go for third one, response = (HttpWebResponse)request.GetResponse(); throws with Connection Timeout exception. WTF? I must point out that I had to create .config for the application in order to allow my headers to be sent out from the application, otherwise it wouldn't work at all. Here it is: <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.net> <settings> <httpWebRequest useUnsafeHeaderParsing = "true" /> </settings> </system.net> </configuration> Does any of this ring a bell?

  • Shopify JSONP issue in ajaxAPI

    - by Aaron U
    I'm getting some odd response back from shopify ajaxapi for jsonp. If you cURL a Shopify ajax api location http://storename.domain.com/cart.json?callback=handler you will get a jsonp response. But something is breaking the same request in browsers. It appears to be related to compression? Here are some responses from each browser when attempting to call the jsonp as documented.

Internet Explorer: Internet Explorer cannot display the webpage Chrome/Safari/Webkit: Cannot decode raw data, or failed (chrome) Attempted use via jquery: $.getJSON('http://storename.domain.com/cart.json?callback=?', function(data) { ... }); // Results in a failed request, viewable network request panels of dev tools Here is some output from cURL including response headers: $ curl -i http://storename.domain.com/cart.json?callback=CALLBACK_FUNC HTTP/1.1 200 OK Server: nginx Date: Tue, 18 Dec 2012 13:48:29 GMT Content-Type: application/javascript; charset=utf-8 Transfer-Encoding: chunked Connection: keep-alive Status: 200 OK ETag: cachable:864076445587123764313132415008994143575 Cache-Control: max-age=0, private, must-revalidate X-Alternate-Cache-Key: cachable:11795444887523410552615529412743919200 X-Cache: hit, server X-Request-Id: a0c33a55230fe42bce79b462f6fe450d X-UA-Compatible: IE=Edge,chrome=1 Set-Cookie: _session_id=b6ace1d7b0dbedd37f7787d10e173131; path=/; HttpOnly X-Runtime: 0.033811 P3P: CP="NOI DSP COR NID ADMa OPTa OUR NOR" CALLBACK_FUNC({"token":null,"note":null,"attributes":{},"total_price":0,...}) Also related unanswered here: Shopify Ajax API JSONP supported?

  • How to use SQLAlchemy to dump an SQL file from query expressions to bulk-insert into a DBMS?

    - by Mahmoud Abdelkader
    Please bear with me as I explain the problem, how I tried to solve it, and my question on how to improve it is at the end. I have a 100,000 line csv file from an offline batch job and I needed to insert it into the database as its proper models. Ordinarily, if this is a fairly straight-forward load, this can be trivially loaded by just munging the CSV file to fit a schema, but I had to do some external processing that requires querying and it's just much more convenient to use SQLAlchemy to generate the data I want. The data I want here is 3 models that represent 3 pre-exiting tables in the database and each subsequent model depends on the previous model. For example: Model C --> Foreign Key --> Model B --> Foreign Key --> Model A So, the models must be inserted in the order A, B, and C. I came up with a producer/consumer approach: - instantiate a multiprocessing.Process which contains a threadpool of 50 persister threads that have a threadlocal connection to a database - read a line from the file using the csv DictReader - enqueue the dictionary to the process, where each thread creates the appropriate models by querying the right values and each thread persists the models in the appropriate order This was faster than a non-threaded read/persist but it is way slower than bulk-loading a file into the database. The job finished persisting after about 45 minutes. For fun, I decided to write it in SQL statements, it took 5 minutes. Writing the SQL statements took me a couple of hours, though. So my question is, could I have used a faster method to insert rows using SQLAlchemy? As I understand it, SQLAlchemy is not designed for bulk insert operations, so this is less than ideal. This follows to my question, is there a way to generate the SQL statements using SQLAlchemy, throw them in a file, and then just use a bulk-load into the database? I know about str(model_object) but it does not show the interpolated values. I would appreciate any guidance for how to do this faster. Thanks!

  • WCF events in server-side

    - by Eisenrich
    Hi all, I'm working on an application in WCF and want to receive events in the server side. I have a web that upon request needs to register a fingerprint. The web page request the connection of the device and then every second for 15 seconds requests the answer. The server-side code is apparently "simple" but doesn't work. Here is it: [ServiceContract] interface IEEtest { [OperationContract] void EEDirectConnect(); } class EETest : IEEtest { public void EEDirectConnect() { CZ ee = new CZ(); // initiates the device dll ee.Connect_Net("192.168.1.200", 4011); ee.OnFinger += new _IEEEvents_OnFingerEventHandler(ee_OnFinger); } public void ee_OnFinger() { //here i have a breakpoint; } } every time I put my finger, it should fire the event. in fact if I static void Main() { EETest pp = new EETest(); pp.EEDirectConnect(); } It works fine. but from my proxy it doesn't fire the event. do you have any tips, recommendations, or can you see the error? Thanks everyone.

  • storing and retrieving socket

    - by Trevor Newhook
    From what I can understand, once I create a socket, I can then create an array to store it with userArray[socket.nickname]=socket; I can then send a message to it with: io.sockets.socket(userArray[data.to]).emit('private message', tstamp(), socket.nickname, message); The basic logic is to store a copy of each socket in an object, identified by nickname. When I want to send a message to that socket, I use the copy of the socket, and send the message via io.sockets.socket(id).emit(). The entire server code is below: io.sockets.on('connection', function (socket) { socket.on('user message', function (msg) { socket.broadcast.emit('user message', tstamp(), socket.nickname, msg); updateLog('user message', socket.nickname, msg); }); socket.on('private message', function(data) { socket.get(data.nickname, function (err, name) { console.log('Chat message by ', name); }); updateLog('private message', socket.nickname, data.message); message=data.message; io.sockets.socket(userArray[data.to]).emit('private message', tstamp(), socket.nickname, message); }); socket.on('get log', function () { updateLog(); // Ensure old entries are cleared out before sending it. io.sockets.emit('chat log', log); }); socket.on('nickname', function (nick, fn) { var i = 1; var orignick = nick; while (nicknames[nick]) { nick = orignick+i; i++; } fn(nick); nicknames[nick] = socket.nickname = nick; userArray[socket.nickname]=socket; socket.set('nickname', nick, function () { socket.emit('ready'); }); socket.broadcast.emit('announcement', nick + ' connected'); // io.sockets.socket(userArray[nick]).emit('newID', 'Your name is: ' + nick, '. Your ID is: '+ userArray[nick]); io.sockets.emit('nicknames', nicknames); });
