  • paypal ipn working but stopping at 'thank you' page.

    - by Tarique Imam
    I am using the code for controller(CODEIGNITER): function paypal_tran(){ if (empty($_GET['action'])){ $_GET['action'] = 'process';} if($this-uri-segment ( 3 )){ $action=$this-uri-segment ( 3 ); } else{ $action='process'; } $ammount=39.99; $this-lenders_model-paypal_process($action,$this_script,$ammount); $this-load-view('view_paypal_tran'); } function ipn(){ if ($this->paypal_class->validate_ipn()) { $data = array( 'fname'=> 'fname', /* insert the user id */ 'lname'=>'lname' ); //$this->db->insert('ajax_test',$data); // For this example, we'll just email ourselves ALL the data. $subject = 'Instant Payment Notification - Recieved Payment'; $to = '[email protected]'; // your email $body = "An instant payment notification was successfully recieved\n"; $body .= "from ".$p->ipn_data['payer_email']." on ".date('m/d/Y'); $body .= " at ".date('g:i A')."\n\nDetails:\n"; foreach ($this->paypal_class->ipn_data as $key => $value) { $body .= "\n$key: $value"; } mail($to, $subject, $body); } } function success() { $this->load->view('paypal_succ_view'); } AND this is my model: function paypal_process($action,$this_script,$ammount){ switch ($action) { case 'process': // Process and order... // There should be no output at this point. To process the POST data, // the submit_paypal_post() function will output all the HTML tags which // contains a FORM which is submited instantaneously using the BODY onload // attribute. In other words, don't echo or printf anything when you're // going to be calling the submit_paypal_post() function. // This is where you would have your form validation and all that jazz. // You would take your POST vars and load them into the class like below, // only using the POST values instead of constant string expressions. // For example, after ensureing all the POST variables from your custom // order form are valid, you might have: // // $p->add_field('first_name', $_POST['first_name']); // $p->add_field('last_name', $_POST['last_name']); $this->paypal_class->add_field('business', '[email protected]'); $this->paypal_class->add_field('return', $this_script.'/success'); $this->paypal_class->add_field('cancel_return', $this_script.'/cancel'); $this->paypal_class->add_field('notify_url', $this_script.'/ipn'); $this->paypal_class->add_field('item_name', 'Lenders Account for one month'); $this->paypal_class->add_field('amount', $ammount); $this->paypal_class->submit_paypal_post(); // submit the fields to paypal $this->paypal_class->dump_fields(); // for debugging, output a table of all the fields break; PROBLEM IS IPN IS NOT WORKING. THE HIDDEN FIELD HAS VALUE FOR REDIRECT TO IPN, BUT NOT WORKING!!PLS HELP

  • Java RegExp ViewState

    - by CDSO1
    I am porting some functionality from a C++ application to java. This involves reading non-modifiable data files that contain regular expressions. A lot of the data files contain regular expressions that look similar to the following: (?<=id="VIEWSTATE".*?value=").*?(?=") These regular expressions produce the following error: "Look-behind group does not have an obvious maximum length near index XX" In C++ the engine being used supported these expressions. Is there another form of regexp that can produce the same result that can be generated using expressions like my example as input?

  • What are the benefits of using ORM over XML Serialization/Deserialization?

    - by Tequila Jinx
    I've been reading about NHibernate and Microsoft's Entity Framework to perform Object Relational Mapping against my data access layer. I'm interested in the benefits of having an established framework to perform ORM, but I'm curious as to the performance costs of using it against standard XML Serialization and Deserialization. Right now, I develop stored procedures in Oracle and SQL Server that use XML Types for either input or output parameters and return or shred XML depending on need. I use a custom database command object that uses generics to deserialize the XML results into a specified serializable class. By using a combination of generics, xml (de)serialization and Microsoft's DAAB, I've got a process that's fairly simple to develop against regardless of the data source. Moreover, since I exclusively use Stored Procedures to perform database operations, I'm mostly protected from changes in the data structure. Here's an over-simplified example of what I've been doing. static void main() { testXmlClass test = new test(1); test.Name = "Foo"; test.Save(); } // Example Serializable Class ------------------------------------------------ [XmlRootAttribute("test")] class testXmlClass() { [XmlElement(Name="id")] public int ID {set; get;} [XmlElement(Name="name")] public string Name {set; get;} //create an instance of the class loaded with data. public testXmlClass(int id) { GenericDBProvider db = new GenericDBProvider(); this = db.ExecuteSerializable("myGetByIDProcedure"); } //save the class to the database... public Save() { GenericDBProvider db = new GenericDBProvider(); db.AddInParameter("myInputParameter", DbType.XML, this); db.ExecuteSerializableNonQuery("mySaveProcedure"); } } // Database Handler ---------------------------------------------------------- class GenericDBProvider { public T ExecuteSerializable<T>(string commandText) where T : class { XmlSerializer xml = new XmlSerializer(typeof(T)); // connection and command code is assumed for the purposes of this example. // the final results basically just come down to... return xml.Deserialize(commandResults) as T; } public void ExecuteSerializableNonQuery(string commandText) { // once again, connection and command code is assumed... // basically, just execute the command along with the specified // parameters which have been serialized. } public void AddInParameter(string name, DbType type, object value) { StringWriter w = new StringWriter(); XmlSerializer x = new XmlSerializer(value.GetType()); //handle serialization for serializable classes. if (type == DbType.Xml && (value.GetType() != typeof(System.String))) { x.Serialize(w, value); w.Close(); // store serialized object in a DbParameterCollection accessible // to my other methods. } else { //handle all other parameter types } } } I'm starting a new project which will rely heavily on database operations. I'm very curious to know whether my current practices will be sustainable in a high-traffic situation and whether or not I should consider switching to NHibernate or Microsoft's Entity Framework to perform what essentially seems to boil down to the same thing I'm currently doing. I appreciate any advice you may have.

  • Accidental Complexity in OpenSSL HMAC functions

    - by Hassan Syed
    SSL Documentation Analaysis This question is pertaining the usage of the HMAC routines in OpenSSL. Since Openssl documentation is a tad on the weak side in certain areas, profiling has revealed that using the: unsigned char *HMAC(const EVP_MD *evp_md, const void *key, int key_len, const unsigned char *d, int n, unsigned char *md, unsigned int *md_len); From here, shows 40% of my library runtime is devoted to creating and taking down **HMAC_CTX's behind the scenes. There are also two additional function to create and destroy a HMAC_CTX explicetly: HMAC_CTX_init() initialises a HMAC_CTX before first use. It must be called. HMAC_CTX_cleanup() erases the key and other data from the HMAC_CTX and releases any associated resources. It must be called when an HMAC_CTX is no longer required. These two function calls are prefixed with: The following functions may be used if the message is not completely stored in memory My data fits entirely in memory, so I choose the HMAC function -- the one whose signature is shown above. The context, as described by the man page, is made use of by using the following two functions: HMAC_Update() can be called repeatedly with chunks of the message to be authenticated (len bytes at data). HMAC_Final() places the message authentication code in md, which must have space for the hash function output. The Scope of the Application My application generates a authentic (HMAC, which is also used a nonce), CBC-BF encrypted protocol buffer string. The code will be interfaced with various web-servers and frameworks Windows / Linux as OS, nginx, Apache and IIS as webservers and Python / .NET and C++ web-server filters. The description above should clarify that the library needs to be thread safe, and potentially have resumeable processing state -- i.e., lightweight threads sharing a OS thread (which might leave thread local memory out of the picture). The Question How do I get rid of the 40% overhead on each invocation in a (1) thread-safe / (2) resume-able state way ? (2) is optional since I have all of the source-data present in one go, and can make sure a digest is created in place without relinquishing control of the thread mid-digest-creation. So, (1) can probably be done using thread local memory -- but how do I resuse the CTX's ? does the HMAC_final() call make the CTX reusable ?. (2) optional: in this case I would have to create a pool of CTX's. (3) how does the HMAC function do this ? does it create a CTX in the scope of the function call and destroy it ? Psuedocode and commentary will be useful.

  • HTTP Error: 413 Request Entity Too Large

    - by Torben Gundtofte-Bruun
    What I have: I have an iPhone app that sends HTTP POST requests (XML format) to a web service written in PHP. This is on a hosted virtual private server so I can edit httpd.conf and other files on the server, and restart Apache. The problem: The web service works perfectly as long as the request is not too large, but around 1MB is the limit. After that, the server responds with: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>413 Request Entity Too Large</title> </head><body> <h1>Request Entity Too Large</h1> The requested resource<br />/<br /> does not allow request data with POST requests, or the amount of data provided in the request exceeds the capacity limit. </body></html> The web service writes its own log file, and I can see that small messages are processed fine. Larger messages are not logged at all so I guess that something in Apache rejects them before they even reach the web service? Things I've tried without success: (I've restarted Apache after every change. These steps are incremental.) hosting provider's web-based configuration panel: disable mod_security httpd.conf: LimitXMLRequestBody 0 and LimitRequestBody 0 httpd.conf: LimitXMLRequestBody 100000000 and LimitRequestBody 100000000 httpd.conf: SecRequestBodyLimit 100000000 At this stage, Apache's error.log contains a message: ModSecurity: Request body no files data length is larger than the configured limit (1048576) It looks like my step #4 didn't really take, which is consistent with step #1 but does not explain why mod_security appears to be active after all. What more can I try, to get the web service to receive large messages?

  • Optimizing Disk I/O & RAID on Windows SQL Server 2005

    - by David
    I've been monitoring our SQL server for a while, and have noticed that I/O hits 100% every so often using Task Manager and Perfmon. I have normally been able to correlate this spike with SUSPENDED processes in SQL Server Management when I execute "exec sp_who2". The RAID controller is controlled by LSI MegaRAID Storage Manager. We have the following setup: System Drive (Windows) on RAID 1 with two 280GB drives SQL is on a RAID 10 (2 mirroed drives of 280GB in two different spans) This is a database that is hammered during the day, but is pretty inactive at night. The DB size is currently about 13GB, and is used by approximately 200 (and growing) users a day. I have a couple of ideas I'm toying around with: Checking for Indexes & reindexing some tables Adding an additional RAID 1 (with 2 new, smaller, HDs) and moving the SQL's Log Data File (LDF) onto the new RAID. For #2, my question is this: Would we really be increasing disk performance (IO) by moving data off of the RAID 10 onto a RAID 1? RAID 10 obviously has better performance than RAID 1. Furthermore, SQL must write to the transaction logs before writing to the database. But on the flip side, we'll be reducing both the size of the disks as well as the amount of data written to the RAID 10, which is where all of the "meat" is - thereby increasing that RAID's performance for read requests. Is there any way to find out what our current limiting factor is? (The drives vs. the RAID Controller)? If the limiting factor is the drives, then maybe adding the additional RAID 1 makes sense. But if the limiting factor is the Controller itself, then I think we're approaching this thing wrong. Finally, are we just wasting our time? Should we instead be focusing our efforts towards #1 (reindexing tables, reducing network latency where possible, etc...)?

  • Why do I get rows of zeros in my 2D fft?

    - by Nicholas Pringle
    I am trying to replicate the results from a paper. "Two-dimensional Fourier Transform (2D-FT) in space and time along sections of constant latitude (east-west) and longitude (north-south) were used to characterize the spectrum of the simulated flux variability south of 40degS." - Lenton et al(2006) The figures published show "the log of the variance of the 2D-FT". I have tried to create an array consisting of the seasonal cycle of similar data as well as the noise. I have defined the noise as the original array minus the signal array. Here is the code that I used to plot the 2D-FT of the signal array averaged in latitude: import numpy as np from numpy import ma from matplotlib import pyplot as plt from Scientific.IO.NetCDF import NetCDFFile ### input directory indir = '/home/nicholas/data/' ### get the flux data which is in ### [time(5day ave for 10 years),latitude,longitude] nc = NetCDFFile(indir + 'CFLX_2000_2009.nc','r') cflux_southern_ocean = nc.variables['Cflx'][:,10:50,:] cflux_southern_ocean = ma.masked_values(cflux_southern_ocean,1e+20) # mask land nc.close() cflux = cflux_southern_ocean*1e08 # change units of data from mmol/m^2/s ### create an array that consists of the seasonal signal fro each pixel year_stack = np.split(cflux, 10, axis=0) year_stack = np.array(year_stack) signal_array = np.tile(np.mean(year_stack, axis=0), (10, 1, 1)) signal_array = ma.masked_where(signal_array > 1e20, signal_array) # need to mask ### average the array over latitude(or longitude) signal_time_lon = ma.mean(signal_array, axis=1) ### do a 2D Fourier Transform of the time/space image ft = np.fft.fft2(signal_time_lon) mgft = np.abs(ft) ps = mgft**2 log_ps = np.log(mgft) log_mgft= np.log(mgft) Every second row of the ft consists completely of zeros. Why is this? Would it be acceptable to add a randomly small number to the signal to avoid this. signal_time_lon = signal_time_lon + np.random.randint(0,9,size=(730, 182))*1e-05 EDIT: Adding images and clarify meaning The output of rfft2 still appears to be a complex array. Using fftshift shifts the edges of the image to the centre; I still have a power spectrum regardless. I expect that the reason that I get rows of zeros is that I have re-created the timeseries for each pixel. The ft[0, 0] pixel contains the mean of the signal. So the ft[1, 0] corresponds to a sinusoid with one cycle over the entire signal in the rows of the starting image. Here are is the starting image using following code: plt.pcolormesh(signal_time_lon); plt.colorbar(); plt.axis('tight') Here is result using following code: ft = np.fft.rfft2(signal_time_lon) mgft = np.abs(ft) ps = mgft**2 log_ps = np.log1p(mgft) plt.pcolormesh(log_ps); plt.colorbar(); plt.axis('tight') It may not be clear in the image but it is only every second row that contains completely zeros. Every tenth pixel (log_ps[10, 0]) is a high value. The other pixels (log_ps[2, 0], log_ps[4, 0] etc) have very low values.

  • What is the quickest reliable way to backup a NAS drive to a USB drive?

    - by Tim Murphy
    How would you backup 600+ GB of data on a NAS (Network-Attached Storage) drive to a USB external drive? The NAS drive does not contain mission critical data nonetheless I wish to make weekly copies of it just in case. The NAS drive is almost exclusively used as an archive dump and is rarely updated. However the backup strategy used must have a simple restore procedure so I can confidently say the data now on the NAS drive is exactly how it was at the time of backup. I did try xcopy but seemed like it would take many-many hours and eventually crashed with insufficient memory. http://www.ctunion.com/node/114 suggests I would need to use xxcopy instead due to folder/file name lengths. My concern with xcopy/xxcopy is the length of time it takes. Hoping something else is faster. NAS drive is DLink DNS-313. 1TB drive installed. Connected to router via Ethernet cable. USB drive is Seagate 1TB. Can be connected to Windows Vista (preferred) or Windows 7 PCs. Both PCs are usually connected Wirelessly however ethernet cable can be used during backup to speed up the process.

  • Help with iphone dev - beyond bounds error

    - by dusk
    I'm just learning iphone development, so please forgive me for what is probably a beginner error. I've searched around and haven't found anything specific to my problem, so hopefully it is an easy fix. The book has examples of building a table from data hard coded via an array. Unfortunately it never really tells you how to get data from a URL, so I've had to look that up and that is where my problems show up. When I debug in xcode, it seems like the count is correct, so I don't understand why it is going out of bounds? This is the error message: 2010-05-03 12:50:42.705 Simple Table[3310:20b] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray objectAtIndex:]: index (1) beyond bounds (0)' My URL returns the following string: first,second,third,fourth And here is the iphone code with the book's working example commented out #import "Simple_TableViewController.h" @implementation Simple_TableViewController @synthesize listData; - (void)viewDidLoad { /* //working code from book NSArray *array = [[NSArray alloc] initWithObjects:@"Sleepy", @"Sneezy", @"Bashful", @"Bashful", @"Happy", @"Doc", @"Grumpy", @"Thorin", @"Dorin", @"Norin", @"Ori", @"Balin", @"Dwalin", @"Fili", @"Kili", @"Oin", @"Gloin", @"Bifur", @"Bofur", @"Bombur", nil]; self.listData = array; [array release]; */ //code from interwebz that crashes NSString *urlstr = [[NSString alloc] initWithFormat:@"http://www.mysite.com/folder/iphone-test.php"]; NSURL *url = [[NSURL alloc] initWithString:urlstr]; NSString *ans = [NSString stringWithContentsOfURL:url]; NSArray *listItems = [ans componentsSeparatedByString:@","]; self.listData = listItems; [urlstr release]; [url release]; [ans release]; [listItems release]; [super viewDidLoad]; } - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview.

  • Java api to get windows Special folders

    - by SvrGuy
    I once found a nifty little library that used JNI to allow java applications on Windows to get the locations of various "special" directories on windows. I can't for the life of me find it again... In particular, I need to get the location of the "All Users" (shared) "Application Data" directory. So, anyone have a bullet proof way in Java to locate the "All Users" "Application Data" folder? It needs to be bullet proof.

  • primitives of a programming language

    - by Tim
    Hi, Which do the concepts control flow, data type, statement, expression and operation belong to? Syntax or semantics? What is the relation between control flow, data type, statement, expression, operation, function, ...? How a program is built from these primitives level by level? I would like to understand these primitive concepts and their relations in order to figure out what aspects of a new language should one learn. Thanks and regards!

  • Running Debian as guest operating system on a Hyper-V VM

    - by kce
    Hello. Layer-9 considerations are prompting a migration from Citrix XenServer to Hyper-V as our shop's virtualization platform of choice. This will require me to migrate our existing virtual machines from XenServer to Hyper-V. A hand full of these VMs are running Debian. Unfortunately, Debian does not seem to be on the list of approved/supported guest operating systems. In fact it seems that running Debian as a guest operating system of is rather difficult, although apparently not impossible. I have two interrelated questions: Does anyone have any experience running a Debian guest on Hyper-V? Is it one of those things where it just will not work at all or is more along the lines of "it will probably work fine, but we won't support it". Any experience here, positive or negative, would be helpful. How much of a bad idea is it to deviate from Hyper-V's list of supported guest operating systems? Again, is it either basically asking for Bad Things (TM) to happen or is just another instance of "it will probably work fine, but we won't support it"? Or is it somewhere in the middle? Thank you.

  • When using delegates, need better way to do sequential processing

    - by Padawan
    I have a class WebServiceCaller that uses NSURLConnection to make asynchronous calls to a web service. The class provides a delegate property and when the web service call is done, it calls a method webServiceDoneWithXXX on the delegate. There are several web service methods that can be called, two of which are say GetSummary and GetList. The classes that use WebServiceCaller initially need both the summary and list so they are written like this: -(void)getAllData { [webServiceCaller getSummary]; } -(void)webServiceDoneWithGetSummary { [webServiceCaller getList]; } -(void)webServiceDoneWithGetList { ... } This works but there are at least two problems: The calls are split across delegate methods so it's hard to see the sequence at a glance but more important it's hard to control or modify the sequence. Sometimes I want to call just GetSummary and not also GetList so I would then have to use an ugly class-level state variable that tells webServiceDoneWithGetSummary whether to call GetList or not. Assume that GetList cannot be done until GetSummary completes and returns some data which is used as input to GetList. Is there a better way to handle this and still get asynchronous calls? Update based on Matt Long's answer: Using notifications instead of a delegate, it looks like I can solve problem #2 by setting a different selector depending on whether I want the full sequence (GetSummary+GetList) or just GetSummary. Both observers would still use the same notification name when calling GetSummary. I would have to write two separate methods to handle GetSummaryDone instead of using a single delegate method (where I would have needed some class-level variable to tell whether to then call GetList). -(void)getAllData { [[NSNotificationCenter defaultCenter] addObserver:self              selector:@selector(getSummaryDoneAndCallGetList:)                  name:kGetSummaryDidFinish object:nil];     [webServiceCaller getSummary]; } -(void)getSummaryDoneAndCallGetList { [NSNotificationCenter removeObserver] //process summary data [[NSNotificationCenter defaultCenter] addObserver:self              selector:@selector(getListDone:)                  name:kGetListDidFinish object:nil];     [webServiceCaller getList]; } -(void)getListDone { [NSNotificationCenter removeObserver] //process list data } -(void)getJustSummaryData { [[NSNotificationCenter defaultCenter] addObserver:self              selector:@selector(getJustSummaryDone:) //different selector but                  name:kGetSummaryDidFinish object:nil]; //same notification name     [webServiceCaller getSummary]; } -(void)getJustSummaryDone { [NSNotificationCenter removeObserver] //process summary data } I haven't actually tried this yet. It seems better than having state variables and if-then statements but you have to write more methods. I still don't see a solution for problem 1.

  • Update BIOS on Sun Fire X4150 server

    - by Massimo
    I have some Sun Fire X4150 servers with a very old BIOS release (1ADQW015), which seems to have some compatibility problems with WMware ESX Server 3.5 and Windows 2008 R2 virtual machines; so I want to update the BIOS on them. The problem: according to this page, if your servers run ELOM (mine do), you first need to update to the latest ELOM release, then to the interim transition release, then finally you can update to the latest one. Ok, I'm willing to do that... but it looks like Sun (now Oracle) will happily let you download the latest firmware DVD (3.3.0), but it will not let you download the transition release (2.0) if you don't have a support contract. Well, I actuall don't care at all about the servers' management controllers (we don't even use them), so upgrading from ELOM to ILOM is totally irrelevant to me; but I need to update the servers' BIOS. So my question is: can I update the servers' BIOS to the latest version without doing the full ELOM-to-ILOM migration, or will this not work (or even make the servers unusable)? Do BIOS versions and SP ones need to be matched, or can one be updated without bothering with the other? Bonus question: if this whole ELOM-to-ILOM thing actually is needed in order to update the BIOS, can that 2.0 CD-ROM be obtained without having a support contract with Sun/Oracle (which we are definitely not going to sign, being that quite old hardware)? Update: I tried upgrading only the BIOS on one of the servers, and it didn't boot anymore. So it really looks like a full firmware upgrade is needed, and the management controller and BIOS versions should be kept in sync. So... where can I find that *&!£%$% 2.0 CD-ROM? Or at least the transition firmware that can be found on it?

  • Mac updated just now, postgres now broken

    - by Dave
    I run postgres 9.1 / ruby 1.9.2 / rails 3.1.0 on a maxbook air for local dev. It's all been running smoothly for months, (though this is the first time I've done development on a mac.) It's a macbook air from last year, and today I got the mac osx software update message as I have a few times before, and my system downloaded approx 450mb of updates and restarted. It now says it's on OSX 10.7.3. Point is, postgres has stopped working, when I start my thin server (mirror heroku cedar) as normal, and then browse to my rails app I get: PG::Error could not connect to server: Permission denied Is the server running locally and accepting connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"? What happened? After browsing around a few questions I'm still confused, but here's some extra info: Running psql from command line gives same error I can run pgadmin 3 and connect via it and run SQL no problems Running which psql shows the version as /usr/bin/psql I created a PostgreSQL user back when I got the mac (it's always been on lion) I've no idea why, almost certainly I was following a tutorial which I neglected to store in my notes. Point is I am aware there is a _postgres user as well. I know it's rubbish, but apart from a note on passwords, I don't have any extra info on how I configured postgres - though the obvious implication is that I did not use the _postgres user. Anyone have suggestions or information on what might have changed / what I can try to debug and fix? Thanks. Edit: Playing around based on this question and answer: http://stackoverflow.com/questions/7975414/check-status-of-postgresql-server-mac-os-x, see this string of commands: $ sudo su postgreSQL bash-3.2$ /Library/PostgreSQL/9.1/bin/pg_ctl start -D /Library/PostgreSQL/9.1/data pg_ctl: another server might be running; trying to start server anyway server starting bash-3.2$ 2012-04-08 19:03:39 GMT FATAL: lock file "postmaster.pid" already exists 2012-04-08 19:03:39 GMT HINT: Is another postmaster (PID 68) running in data directory "/Library/PostgreSQL/9.1/data"? bash-3.2$ exit

  • Modifying Export to Excel in ReportViewer

    - by firedrawndagger
    I have a formatted table in ReportViewer. When I want to export to Excel though - I do not want to export the formatted table - instead I want to output the original/raw/unmassaged data table in an excel file. What's the best way to intercept the Export to Excel function and output data in a different format?
