  • Allowed memory size of 33554432 bytes exhausted (tried to allocate 93 bytes) error in php

    - by Chris
    I inserted the following code: $counter = 1; while($_POST['additional_contact1'] != '' || $_POST['additional_contact2'] != '' || $_POST['additional_contact3'] != '') { if($_POST['additional_contact' . $counter] != '') { $_SESSION['contact'][$counter]['additional_contact'] = $_POST['additional_contact' . $counter]; $_SESSION['contact'][$counter]['additional_int_prefix'] = $_POST['additional_int_prefix' . $counter]; $_SESSION['contact'][$counter]['additional_prefix'] = $_POST['additional_prefix' . $counter]; $_SESSION['contact'][$counter]['additional_first'] = $_POST['additional_first' . $counter]; $_SESSION['contact'][$counter]['additional_last'] = $_POST['additional_last' . $counter]; } else { $_SESSION['contact'][$counter]['additional_contact'] = null; $_SESSION['contact'][$counter]['additional_int_prefix'] = null; $_SESSION['contact'][$counter]['additional_prefix'] = null; $_SESSION['contact'][$counter]['additional_first'] = null; $_SESSION['contact'][$counter]['additional_last'] = null; } $counter++; } and I received this error: Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 93 bytes) I tried to increase the memory limit with ini_set(), but it still won't work at 96M. What am I doing wrong with my code to make it need so much memory? How can I solve this problem?

  • Pylons error "No object (name: request) has been registered for this thread" with debug = false

    - by Evgeny
    I'm unable to access the request object in my Pylons 0.9.7 controller when I set debug = false in the .ini file. I have the following code: def run_something(self): print('!!! request = %r' % request) print('!!! request.params = %r' % request.params) yield 'Stuff' With debugging enabled this works fine and prints out: !!! request = <Request at 0x9571190 POST http://my_url> !!! request.params = UnicodeMultiDict([... lots of stuff ...]) If I set debug = false I get the following: !!! request = <paste.registry.StackedObjectProxy object at 0x4093790> Error - <type 'exceptions.TypeError'>: No object (name: request) has been registered for this thread The stack trace confirms that the error is on the print('!!! request.params = %r' % request.params) line. I'm running it using the Paste server and these two lines are the very first lines in my controller method. This only occurs if I have yield statements in the method (even though the statements aren't reached). I'm guessing Pylons sees that it's a generator method and runs it on some other thread. My questions are: How do I make it work with debug = false ? Why does it work with debug = true ? Obviously this is quite a dangerous bug, since I normally develop with debug = true, so it can go unnoticed during development.

  • vHost RewriteRule is creating a 500 Error

    - by Andrew Ellis
    Hello, Below you will find my current vHost entry that I am using for a site that I currently have under development.

  • Encoding / Error Correction Challenge

    - by emi1faber
    Is it mathematically feasible to encode and initial 4 byte message into 8 bytes and if one of the 8 bytes is completely dropped and another is wrong to reconstruct the initial 4 byte message? There would be no way to retransmit nor would the location of the dropped byte be known. If one uses Reed Solomon error correction with 4 "parity" bytes tacked on to the end of the 4 "data" bytes, such as DDDDPPPP, and you end up with DDDEPPP (where E is an error) and a parity byte has been dropped, I don't believe there's a way to reconstruct the initial message (although correct me if I am wrong)... What about multiplying (or performing another mathematical operation) the initial 4 byte message by a constant, then utilizing properties of an inverse mathematical operation to determine what byte was dropped. Or, impose some constraints on the structure of the message so every other byte needs to be odd and the others need to be even. Alternatively, instead of bytes, it could also be 4 decimal digits encoded in some fashion into 8 decimal digits where errors could be detected & corrected under the same circumstances mentioned above - no retransmission and the location of the dropped byte is not known. I'm looking for any crazy ideas anyone might have... Any ideas out there?

  • Microsoft OLE DB Provider for SQL Server error '80040e14' Could not find stored procedure

    - by BBlake
    I am migrating a classic ASP web app to new servers. The database back end is migrating from SQL Server 2000 to SQL Server 2008, and the app is moving from Win2000 x86 to Win2003R2 x64. I am getting the above error on every single stored procedure call within the application. I have verified: Yes, the SQL user is set up, using correct username and password Yes, the SQL user has execute permissions on the stored procedures in the database Yes, I have updated the TypeLib references to the new UUID Yes, I have logged into the database via SSMS with the SQL user id and it can see and execute the stored procedures just fine in SSMS, but not from the web app. Yes, the SQL user has the database set as its default database. The most frustrating thing is it works fine on the DEV server, but not on the production server. I have gone through every IIS setting 5 or 6 times and the web app is set up precisely the same in both environments. The only difference is the database server name in the connection string (DEV vs prod) EDIT: I have also tried pointing the prod web box at the dev database server and get the same error so I'm fairly sure the issue isn't on the database side.

  • Getting Error When Opening Files

    - by Nathan Campos
    I'm developing a simple Text Editor to understand better PocketC language, then I've done this: #include "\\Storage Card\\My Documents\\PocketC\\Parrot\\defines.pc" int filehandle; int file_len; string file_mode; initComponents() { createctrl("EDIT", "test", 2, 1, 0, 24, 70, 25, TEXTBOX); wndshow(TEXTBOX, SW_SHOW); guigetfocus(); } main() { filehandle = fileopen(OpenFileDlg("Plain Text Files (*.txt)|*.txt; All Files (*.*)|*.*"), 0, FILE_READWRITE); file_len = filegetlen(filehandle); if(filehandle = -1) { MessageBox("File Could Not Be Found!", "Error", 3, 1); } initComponents(); editset(TEXTBOX, fileread(filehandle, file_len)); } Then I tried to run the application, it opens the Open File Dialog, I select a file(that is at \test.txt) that I've created with notepad, then I got my MessageBox saying that the file wans't found. Then I want to know why I'm getting this if the file is all correct? *PS: When I click to exit the MessageBox, I saw that the TextBox is displaying where the file is(I've tested with many other files, and with all I got the error and this).

  • error: expected constructor, destructor, or type conversion before '(' token

    - by jonathanasdf
    include/TestBullet.h:12: error: expected constructor, destructor, or type conver sion before '(' token I hate C++ error messages... lol ^^ Basically, I'm following what was written in this post to try to create a factory class for bullets so they can be instantiated from a string, which will be parsed from an xml file, because I don't want to have a function with a switch for all of the classes because that looks ugly. Here is my TestBullet.h: #pragma once #include "Bullet.h" #include "BulletFactory.h" class TestBullet : public Bullet { public: void init(BulletData& bulletData); void update(); }; REGISTER_BULLET(TestBullet); <-- line 12 And my BulletFactory.h: #pragma once #include <string> #include <map> #include "Bullet.h" #define REGISTER_BULLET(NAME) BulletFactory::reg<NAME>(#NAME) #define REGISTER_BULLET_ALT(NAME, CLASS) BulletFactory::reg<CLASS>(NAME) template<typename T> Bullet * create() { return new T; } struct BulletFactory { typedef std::map<std::string, Bullet*(*)()> bulletMapType; static bulletMapType map; static Bullet * createInstance(char* s) { std::string str(s); bulletMapType::iterator it = map.find(str); if(it == map.end()) return 0; return it->second(); } template<typename T> static void reg(std::string& s) { map.insert(std::make_pair(s, &create<T>)); } }; Thanks in advance.

  • C programming: Dereferencing pointer to incomplete type error

    - by confusedKid
    Hi, I am pretty rusty at C, and I'm getting a dereferencing error. Hopefully someone can help me with this? ^_^ I have a struct defined as: struct { char name[32]; int size; int start; int popularity; } stasher_file; and an array of pointers to those structs: struct stasher_file *files[TOTAL_STORAGE_SIZE]; In my code, I'm making a pointer to the struct and setting its members, and adding it to the array: ... struct stasher_file *newFile; strncpy(newFile-name, name, 32); newFile-size = size; newFile-start = first_free; newFile-popularity = 0; files[num_files] = newFile; ... I'm getting a "error: dereferencing pointer to incomplete type" whenever I try to access the members inside newFile. What am I doing wrong? Thanks very much for any help :)

  • postgres - ERROR: operator does not exist

    - by cino21122
    Again, I have a function that works fine locally, but moving it online yields a big fat error... Taking a cue from a response in which someone had pointed out the number of arguments I was passing wasn't accurate, I double-checked in this situation to be certain that I am passing 5 arguments to the function itself... Query failed: ERROR: operator does not exist: point <@> point HINT: No operator matches the given name and argument type(s). You may need to add explicit type casts.

  • Linker error: wants C++ virtual base class destructor

    - by jdmuys
    Hi, I have a link error where the linker complains that my concrete class's destructor is calling its abstract superclass destructor, the code of which is missing. This is using GCC 4.2 on Mac OS X from XCode. I saw http://stackoverflow.com/questions/307352/g-undefined-reference-to-typeinfo but it's not quite the same thing. Here is the linker error message: Undefined symbols: "ConnectionPool::~ConnectionPool()", referenced from: AlwaysConnectedConnectionZPool::~AlwaysConnectedConnectionZPool()in RKConnector.o ld: symbol(s) not found collect2: ld returned 1 exit status Here is the abstract base class declaration: class ConnectionPool { public: static ConnectionPool* newPool(std::string h, short p, std::string u, std::string pw, std::string b); virtual ~ConnectionPool() =0; virtual int keepAlive() =0; virtual int disconnect() =0; virtual sql::Connection * getConnection(char *compression_scheme = NULL) =0; virtual void releaseConnection(sql::Connection * theConnection) =0; }; Here is the concrete class declaration: class AlwaysConnectedConnectionZPool: public ConnectionPool { protected: <snip data members> public: AlwaysConnectedConnectionZPool(std::string h, short p, std::string u, std::string pw, std::string b); virtual ~AlwaysConnectedConnectionZPool(); virtual int keepAlive(); // will make sure the connection doesn't time out. Call regularly virtual int disconnect(); // disconnects/destroys all connections. virtual sql::Connection * getConnection(char *compression_scheme = NULL); virtual void releaseConnection(sql::Connection * theConnection); }; Needless to say, all those members are implemented. Here is the destructor: AlwaysConnectedConnectionZPool::~AlwaysConnectedConnectionZPool() { printf("AlwaysConnectedConnectionZPool destructor call"); // nothing to destruct in fact } and also maybe the factory routine: ConnectionPool* ConnectionPool::newPool(std::string h, short p, std::string u, std::string pw, std::string b) { return new AlwaysConnectedConnectionZPool(h, p, u, pw, b); } I can fix this by artificially making my abstract base class concrete. But I'd rather do something better. Any idea? Thanks

  • Is this WPF error handling a good idea ?

    - by Adiel
    I have a multi threaded wpf application with various HW interfaces. I want to react to several HW failures that can happen. For example : one of the interfaces is a temperature sensor and i want that from a certain temp. a meesage would appear and notify the user that it happened. i came up with the follwing design : /// <summary> /// This logic reacts to errors that occur during the system run. /// The reaction is set by the component that raised the error. /// </summary> public class ErrorHandlingLogic : Logic { } the above class would consume ErrorEventData that holds all the information about the error that occurred. public class ErrorEventData : IEventData { #region public enum public enum ErrorReaction { } #endregion public enum #region Private Data Memebers and props private ErrorReaction m_ErrorReaction; public ErrorReaction ErrorReactionValue { get { return m_ErrorReaction; } set { m_ErrorReaction = value; } } private string m_Msg; public string Msg { get { return m_Msg; } set { m_Msg = value; } } private string m_ComponentName; public string ComponentName { get { return m_ComponentName; } set { m_ComponentName = value; } } #endregion Private Data Memebers and props public ErrorEventData(ErrorReaction reaction, string msg, string componenetName) { m_ErrorReaction = reaction; m_Msg = msg; m_ComponentName = componenetName; } } the above ErrorHandlingLogic would decide what to do with the ErrorEventData sent to him from various components of the application. if needed it would be forwarded to the GUI to display a message to the user. so what do you think is it a good design ? thanks, Adiel.

  • Fatal error with Custom Magento Module on one server but not the other

    - by Jack
    Hi, I am creating my own custom module in Magento and during testing on a Litespeed server (PHP v5.2.14) I am getting a Fatal Error: Call to a member function batch() on a non-object in ../../../BatchController.php on line 25 that was not appearing during testing on another linux server and a wamp server (PHP v5.2.11). This one has stumped me. I am guessing it has something to do with the server configuration rather than the code itself. But i am just guessing. I was hoping someone here could tell me. The only real major difference I could see, aside from the php versions and environment, is that the server that the error is on is using the Suhosin Patch. But would that be something that could cause this? The line in question is Mage::getModel('mymodule/mymodel')->batch(); which is enclosed in an IF statement. batch() is a public function located in my model file. If you need more code let me know. Thanks!

  • Entity Framework 4 Code First and the new() Operator

    - by Eric J.
    I have a rather deep hierarchy of objects that I'm trying to persist with Entity Framework 4, POCO, PI (Persistence Ignorance) and Code First. Suddenly things started working pretty well when it dawned on me to not use the new() operator. As originally written, the objects frequently use new() to create child objects. Instead I'm using my take on the Repository Pattern to create all child objects as needed. For example, given: class Adam { List<Child> children; void AddChildGivenInput(string input) { children.Add(new Child(...)); } } class Child { List<GrandChild> grandchildren; void AddGrandChildGivenInput(string input) { grandchildren.Add(new GrandChild(...)); } } class GrandChild { } ("GivenInput" implies some processing not shown here) I define an AdamRepository like: class AdamRepository { Adam Add() { return objectContext.Create<Adam>(); } Child AddChildGivenInput(Adam adam, string input) { return adam.children.Add(new Child(...)); } GrandChild AddGrandchildGivenInput(Child child, string input) { return child.grandchildren.Add(new GrandChild(...)); } } Now, this works well enough. However, I'm no longer "ignorant" of my persistence mechanism as I have abandoned the new() operator. Additionally, I'm at risk of an anemic domain model since so much logic ends up in the repository rather than in the domain objects. After much adieu, a question: Or rather several questions... Is this pattern required to work with EF 4 Code First? Is there a way to retain use of new() and still work with EF 4 / POCO / Code First? Is there another pattern that would leave logic in the domain object and still work with EF 4 / POCO / Code First? Will this restriction be lifted in later versions of Code First support? Sometimes trying to go the POCO / Persistence Ignorance route feels like swimming upstream, other times it feels like swimming up Niagra Falls.

  • Axis 1.4 Java: Modify HTTP response code

    - by Achim Bitzer
    Hello, Is there a way to modify the HTTP response code when using apache axis 1.4 for java? This would be useful for testing purposes, for example simulating server side errors. I've already tried the following: Set the HTTP code directly in the http servlet Request: MessageContext context = MessageContext.getCurrentContext(); HttpServletResponse response = (HttpServletResponse) context.getProperty( HTTPConstants.MC_HTTP_SERVLETRESPONSE); response.setStatus(e.getErrorCode()); // no effect Set the HTTP code as axis message context property: MessageContext context = MessageContext.getCurrentContext(); context.setProperty(HTTPConstants.MC_HTTP_STATUS_CODE, e.getErrorCode()); But this didn't seem to work, the actual HTTP code always was 200. Any ideas would be greatly appreciated :-) Greetings, Achim Bitzer

  • Why use short-circuit code?

    - by Tim Lytle
    Related Questions: Benefits of using short-circuit evaluation, Why would a language NOT use Short-circuit evaluation?, Can someone explain this line of code please? (Logic & Assignment operators) There are questions about the benefits of a language using short-circuit code, but I'm wondering what are the benefits for a programmer? Is it just that it can make code a little more concise? Or are there performance reasons? I'm not asking about situations where two entities need to be evaluated anyway, for example: if($user->auth() AND $model->valid()){ $model->save(); } To me the reasoning there is clear - since both need to be true, you can skip the more costly model validation if the user can't save the data. This also has a (to me) obvious purpose: if(is_string($userid) AND strlen($userid) > 10){ //do something }; Because it wouldn't be wise to call strlen() with a non-string value. What I'm wondering about is the use of short-circuit code when it doesn't effect any other statements. For example, from the Zend Application default index page: defined('APPLICATION_PATH') || define('APPLICATION_PATH', realpath(dirname(__FILE__) . '/../application')); This could have been: if(!defined('APPLICATION_PATH')){ define('APPLICATION_PATH', realpath(dirname(__FILE__) . '/../application')); } Or even as a single statement: if(!defined('APPLICATION_PATH')) define('APPLICATION_PATH', realpath(dirname(__FILE__) . '/../application')); So why use the short-circuit code? Just for the 'coolness' factor of using logic operators in place of control structures? To consolidate nested if statements? Because it's faster?

  • HTML table to “graphical text” for code comments

    - by Atif Aziz
    Is there a tool (ideally command-line-based) that can help in converting the source to HTML tables into “graphical text” (think perhaps ASCII art for HTML tables) for use in code comments (like /*…*/), as show below? /* +--------------------------------------------------------------------+ | Network | +--------------------------------------------------------------------+ | 11.05.2010 | ABC | DEF | +------------+-------------+-------------+-------------+-------------+ | | INPUT | OUTPUT | INPUT | OUTPUT | +------------+-------------+-------------+-------------+-------------+ | Value | 366,899,791 | 0 | 213,001 | 2,132,827 | +------------+-------------+-------------+-------------+-------------+ */ Background: A piece of code that reads values from HTML tables can be annotated with comments depicting text-based graphical representations of complex HTML table layouts. Someone maintaining the code later can then find it easier to understand, for example, how a piece of code is slicing and dicing an HTML table or plucking values at certain cell positions.

  • HTTP 404 Error manifests itself as EndPointNotFoundException on a WCF client

    - by dudia
    How can I make my client treat 404 Error correctly? Right now it catches a general exception... My WCF Server uses WebOperationContext.Current.OutgoingResponse.SetStatusAsNotFound(); To return a 404 Error code however my WCF client interperts it as an EndPointNotFoundException There was no endpoint listening at http://myUrl that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. The inner exception is WebException "The remote server returned an error: (404) Not Found.
