WHMCS Fatal error: Out of memory while View Invoice PDF

- by prakash

I can log into WHMCS & can access everything I should be able to access, but if i try to click View PDF Invoice, the following error will occur, Fatal error: Out of memory (allocated 67633152) (tried to allocate 76 bytes) in /home/xxxx/public_html/whmcs/includes/classes/class.tcpdf.php on line 8419 I have already set the allocated Memory limit to 256MB, but the error still occurs. At that time of the error, the process memory is exceeding the allocation I set. I checked log file, and found the following errors: #2 /home/xxxxx/public_html/client/includes/classes/class.tcpdf.php(8453): TCPDF->Image('/home/xxxxx/...', 20, 25, 75, 17.5816023739, 'PNG', '', '', false, 300, '', false, 8) #3 /home/xxxxx/public_html/client/includes/classes/class.tcpdf.php(7881): TCPDF->ImagePngAlpha('/home/xxxxx/...', 20, 25, 337, 79, 75, 17.5816023739, 'PNG', '', '', false, 300, '', NULL) While I was investigating the issue above I also noticed the error condition pictured below:

Kernel Panic Fatal Machine Check

- by 0x4a6f4672

I have got a new Samsung Series 7 laptop with dual boot setup for Windows 8 and Ubuntu 12.10. The Ubuntu installation was quite a hassle, but with the help of Boot Repair finally it seemed to work. Or so I thought. Windows 8 starts fine, but if I want to start Ubuntu regularly the following error occurs, quite similar to this one [Hardware Error] CPU 1: Machine Check Exception: 5 Bank 6 [Hardware Error] RIP !inexact! 33 <00007fab2074598a> [Hardware Error] TSC 95b623464c ADDR fe400 MISC 3880000086 .. [similar messages for CPU 2,3 and 0] .. [Hardware Error] Machine Check: Processor context corrupt Kernel panic - not syncing: Fatal Machine Check Rebooting in 30 seconds Kernel panic does not sound good. Then it starts to reboot, and the second boot trial often works. Is it a Kernel or driver problem? The laptop has an Intel Core i7 processor. I already deactivated Hyperthreading in the BIOS, but it does not seem to help :-(

Error handling in PHP

- by Industrial

Hi guys, We're building a PHP app based on Good old MVC (codeigniter framework) and have run into trouble with a massive chained action that consists of multiple model calls, that together is a part of a big transaction to the database. We want to be able to do a list of actions and get a status report of each one back from the function, whatever the outcome is. Our first initial idea was to utilize the exceptions of PHP5, but since we want to also need status messages that doesnt break the execution of the script, this was our solution that we came up with. It goes a little something like this: $sku = $this->addSku( $name ); if ($sku === false) { $status[] = 'Something gone terrible wrong'; $this->db->trans_rollback(); return $status; } $image= $this->addImage( $filename); if ($image=== false) { $error[] = 'Image could not be uploaded, check filesize'; $this->db->trans_rollback(); return $status; } Our controller looks like this: $var = $this->products->addProductGroup($array); if (is_array($var)) { foreach ($var as $error) { echo $error . '<br />'; } } It appears to be a very fragile solution to do what we need, but it's neither scalable, neither effective when compared to pure PHP exceptions for instance. Is this really the way that this kind of stuff generally is handled in MVC based apps? Thanks!

PHP MVC error handling, view display and user permissions

- by cen

I am building a moderation panel from scratch in a MVC approach and a lot of questions cropped up during development. I would like to hear from others how they handle these situations. Error handling Should you handle an error inside the class method or should the method return something anyway and you handle the error in controller? What about PDO exceptions, how to handle them? For example, let's say we have a method that returns true if the user exists in a table and false if he does not exist. What do you return in the catch statement? You can't just return false because then the controller assumes that everything is alright while the truth is that something must be seriously broken. Displaying the error from the method completely breaks the whole design. Maybe a page redirect inside the method? The proper way to show a view The controller right now looks something like this: include('view/header.php'); if ($_GET['m']=='something') include('view/something.php'); elseif ($_GET['m']=='somethingelse') include('view/somethingelse.php'); include('view/foter.php'); Each view also checks if it was included from the index page to prevent it being accessed directly. There is a view file for each different document body. Is this way of including different views ok or is there a more proper way? Managing user rights Each user has his own rights, what he can see and what he can do. Which part of the system should verify that user has the permission to see the view, controller or view itself? Right now I do permission checks directly in the view because each view can contain several forms that require different permissions and I would need to make a seperate file for each of them if it was put in the controller. I also have to re-check for the permissions everytime a form is submitted because form data can be easily forged. The truth is, all this permission checking and validating the inputs just turns the controller into a huge if/then/else cluster. I feel like 90% of the time I am doing error checks/permissions/validations and very little of the actual logic. Is this normal even for popular frameworks?

Good SQL error handling in Strored Procedure

- by developerit

When writing SQL procedures, it is really important to handle errors cautiously. Having that in mind will probably save your efforts, time and money. I have been working with MS-SQL 2000 and MS-SQL 2005 (I have not got the opportunity to work with MS-SQL 2008 yet) for many years now and I want to share with you how I handle errors in T-SQL Stored Procedure. This code has been working for many years now without a hitch. N.B.: As antoher "best pratice", I suggest using only ONE level of TRY … CATCH and only ONE level of TRANSACTION encapsulation, as doing otherwise may not be 100% sure. BEGIN TRANSACTION; BEGIN TRY -- Code in transaction go here COMMIT TRANSACTION; END TRY BEGIN CATCH -- Rollback on error ROLLBACK TRANSACTION; -- Raise the error with the appropriate message and error severity DECLARE @ErrMsg nvarchar(4000), @ErrSeverity int; SELECT @ErrMsg = ERROR_MESSAGE(), @ErrSeverity = ERROR_SEVERITY(); RAISERROR(@ErrMsg, @ErrSeverity, 1); END CATCH; In conclusion, I will just mention that I have been using this code with .NET 2.0 and .NET 3.5 and it works like a charm. The .NET TDS parser throws back a SQLException which is ideal to work with.

WPF Application doesn't work on some machines: Stopped working error

My WPF application works fine on a number of machines, but now I get a report about this error on a user machine: Description: Stopped working Problem signature: Problem Event Name: CLR20r3 Problem Signature 01: mysoftware.exe Problem Signature 02: 1.0.0.1 Problem Signature 03: 4bbcd9d9 Problem Signature 04: PresentationFramework Problem Signature 05: 3.0.0.0 Problem Signature 06: 4a174fbc Problem Signature 07: 624f Problem Signature 08: e1 Problem Signature 09: System.Windows.Markup.XamlParse OS Version: 6.1.7600.2.0.0.256.48 Locale ID: 1033 I was trying to catch Exception using Application DispatcherUnhandledException but this didn't help. And warping Window1 constructor in try/catch block too. .NET Framework 3.5 is installed on that machine. How can I figure out the reason of crashing: log this error, debug, ...?

mySQL: Select WHERE causes error - why?

- by Industrial

Hi everybody, I have this query: SELECT `manufacturers`.*, `languages`.*, COUNT(`products`.`id`) AS productcount FROM (`manufacturers`) WHERE manufacturers.flushed = 0 JOIN `languages` ON `manufacturers`.`lang` = `languages`.`id` LEFT OUTER JOIN `products` ON `products`.`manuf` = `manufacturers`.`mid` GROUP BY manufacturers.id ORDER BY `languages`.`id` asc, `manufacturers`.`mid` asc; Without the WHERE row, everything works great, but with it, I get a Error 1064 (Syntax error) thrown in my face. I guess that it has something to do with the actual placement of the WHERE row in the query, so I tried to move it around, but without any luck. What can I do?

Displaying Datamatrix in application error screen

- by DaveNay

Quite often we will get a report from a user in the field saying there was an error in our application. Frequently this leads to the typical round of "What was the error?" "I don't know, it was just an error." We of course log these faults to the log files, and we can even enable detailed debug logs, but this involves the end user changing a setting in the configuration file and then finding the correct files and then emailing them to us. As I'm sure you can all imagine, there are plenty of pitfalls and alligators in this methodology. Recently a couple of people have used their cell phone to email me a "screen capture" of the fault, and while this helps, we still have to scrutinize the image to find the exact fault, and if enabled, the stack trace. So this evening, I had the brilliant idea (IMHO) to encode the fault into a Datamatrix barcode image and then encourage users to send me a picture from their cell phone. I can then decode the datamatrix and get a parse-able error message! Our core technology is machine vision, so the decoding of the datamatrix image would be trivial, I just need to find a method of generating the actual image to display in the fault handler. Thoughts?

SQL SERVER – FIX : ERROR : 4214 BACKUP LOG cannot be performed because there is no current database

- by pinaldave

I recently got following email from one of the reader. Hi Pinal, Even thought my database is in full recovery mode when I try to take log backup I am getting following error. BACKUP LOG cannot be performed because there is no current database backup. (Microsoft.SqlServer.Smo) How to fix it? Thanks, [name and email removed as requested] Solution / Fix: This error can happen when you have never taken full backup of your database and you try to attempt to take backup of the log only. Take full backup once and attempt to take log back up. If the name of your database is MyTestDB follow procedure as following. BACKUP DATABASE [MyTestDB] TO DISK = N'C:\MyTestDB.bak' GO BACKUP LOG [MyTestDB] TO DISK = N'C:\MyTestDB.bak' GO Reference: Pinal Dave (http://blog.SQLAuthority.com) Filed under: Pinal Dave, SQL, SQL Authority, SQL Backup and Restore, SQL Error Messages, SQL Query, SQL Scripts, SQL Server, SQL Tips and Tricks, T SQL, Technology Tagged: SQL Log

Different callbacks for error or error as first argument?

- by Florian Margaine

We (and the JS SO chat room) had a talk with @rlemon some days ago about his Little-XHR library about error handling. Basically, we wanted to decide which error handling pattern should be used: xhr.get({ // Some parameters, and then success: function(data) {}, failure: function(data) {} }) Or: xhr.get({ // Some parameters, and then callback: function(err, data) {} }) One is more jQuery-like, while the other is more Node-like. Some say that the first pattern makes you think more about handling error. I think the opposite, since you may forget the other callback function, while the argument is always there on the second pattern. Any opinion/advantage/drawback about both these patterns?

Translating error messages from an external API?

- by Jan Fabry

If I am localizing a piece of software that uses an external API, how should I handle error messages that originate in this API? I do not control the API, I only consume it. The error responses are not very structured: some contain error codes, some contain verbose details in the text, others almost nothing. Some errors can be fixed by the user (incorrect configuration), some are caused by the external service (server overload), some could be caused by a bug in my software (of course, this would be very unlikely...). I would like to provide a smooth experience to my end-users, so they know what went wrong and what they can do to fix it. What is the best strategy to use here? (This is a generalization of a question from the WordPress Stack Exchange. I thought it would be worth re-asking here, because it is not limited to WordPress plugins.)

System Error Report /usr/bin/Xorg

- by jimirings

I have recently begun getting a System Error Report message when I start up my computer. I haven't installed anything recently other than the usual updates or done anything else out of the ordinary. The details for the report just say "/usr/bin/Xorg". It doesn't seem to be causing me any problems beyond the annoying error message. I saw these questions regarding this problem: System Error Report - Xorg How do I enable or disable Apport? That's all dandy for getting the message to go away, but I'd rather fix the problem. Any ideas how I can make that happen? I'm running Ubuntu 12.04 on a Toshiba NB505. I am, of course, happy to provide any other relevant information that may be needed. Thanks in advance.

error: you need to load kernel first

- by Angelos318

I made a clean install on my Sony Vaio laptop, of Ubuntu 11.10 and when the installation was ready, it prompted to remove the usb I was installing the distro from, and press enter to reboot. After this reboot the first thing I got was the following error: error: couldn't read file error: you need to load the kernel first Press any key to continue.. After that it throws me back to the Grub select screen: Ubuntu, with linux 3.0.0-14-generic-pae recovery mode previous linux versions (none since I made a clean install) memory test If i choose the first option it shows only a black screen and never loads anything. If i reboot the same thing happens. Could I repair this using boot-repair? Is there any other way? Note: I know nothing about linux code so i am a total noob on this one Update: boot-repair did not help Grub.cfg here: http://pastebin.com/GKLuDuhM Boot Info Script: http://pastebin.com/indARkKJ

dpkg reports error on package icaclient

- by Photonics1

I installed the icaclient (it's a client for Citrix) a while back. I don't exactly remember what I did to get it working but it was enervating. I had to install some old packages not even avaiable for ubuntu (12.04) and in the end I used some stuff from old rpms. Anyway the client is more or less working now but I always get a dpkg error when installing or updating something. The (translated) error message is something like: dpkg: Error while processing icaclient:i386 (--configure): subprocess installed post-installation-script return errorcode 2 I just want to tell dpkg to ignore this or remove this post-install-script but I don't know how. Thanks!

Hard disk error

I got this error during installation. "The installer encountered an error copying files to the hard disk: [Errno 5] Input/output error This is often due to a faulty CD/DVD disk or drive, or a faulty hard disk. It may help to clean the CD/DVD, to burn the CD/DVD at a lower speed, to clean the CD/DVD drive lens (cleaning kits are often available from electronics suppliers), to check whether the hard disk is old and in need of replacement, or to move the system to a cooler environment." how can i fix this and what does it mean specifically? i'm installing via usb so it can't be the CD. the laptop is recent so it cant be an old HD.

Get more error information from unhandled error

- by Andrew Simpson

I am using C# in a desktop application. I am calling a DLL written in C that I do not have the source code for. Whenever I call this DLL I get an untrapped error which I trap in an UnhandledException event/delegate. The error is : object reference not set to an instance of an object But the stack trace is empty. When I Googled this the info back was that the error was being hanlded eleswhere and then rethrown. But this can only be in the DLL I do not have the source code for. So, is there anyway I can get more info about this error? This is my code... in program.cs... AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException); static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e) { try { Exception _ex = (Exception)e.ExceptionObject; //the stact trace property is empty here.. } finally { Application.Exit(); } } My DLL... [DllImport("AutoSearchDevice.dll", EntryPoint = "Start", ExactSpelling = false, CallingConvention = CallingConvention.StdCall)] public static extern int Start(int ASD_HANDLE); An I call it like so: public static void AutoSearchStart() { try { Start(m_pASD); } catch (Exception ex) { } }

How to pass non-fatal warnings from a library

- by wRAR

A library function parses a file and returns an object. If a parser encounters unknown data, missing values etc., it shouldn't throw an exception and stop parsing (because this is not fatal), but there should be a way to pass information about these things to a caller (so that warnings can be displayed in the UI, for example). How can these warning be returned? I'm thinking of passing a callback function/object into the library, are there any other possible solutions?

Access Error when running windows program

I have a windows form application that uses microsoft access for the database on the backend. When I run that application I get an error that says access is not installed on the computer. I thought that if I included the reference that it will be included with what I release so the user would not have to have access installed. How do I include the Access Runtime to be distributed/installed when my application is installed?
