  • osCommerce custom PHP page

    - by Afrosimon
    Hello! One of my client has an old osCommerce website and while working on it I have to implement what I would call "custom php page", i.e. a page which query a MySQL table, not related to osCommerce, and list the result. I'm not sure of the version, this trick I have seen a lot didn't gave me any result : http://www.clubosc.com/how-to-know-what-version-of-oscommerce-you-are-using.html . And I'm having a hard time doing this seemingly simple task, since osCommerce doesn't allow any php code in the page creation, and I didn't find any module giving me this possibility (not that it is easy to search in this mess : http://addons.oscommerce.com/). At this point I figured it would be easier to just hack'n slash through the code and come up with a custom page : I copied the index.php (the entry point in the application) : <?php require('includes/application_top.php'); if(!$smarty->is_cached($sContentPage, $sCachingGroup)) { //we switch on the content recognition require('includes/pages/' . $sContentClass . '.php'); } $smarty->display($sContentPage, $sCachingGroup); require(DIR_WS_INCLUDES . 'application_bottom.php'); ?> Here I gave a specific value to $sContentClass (with or without the if makes no difference) and customize the corresponding PHP file so it show my custom content but also initialize the same variable than those other PHP file in the pages/ folder. But alas, all of this curious and dubious code simply return me the home page. So here I am, is there an osCommerce Guru around here, or would anyone has a better idea (oh and I also posted on the osCommerce forum, but I'm still waiting for a response...)? Thanks a lot in advance.

  • What is the equivalent of .NET events in Ruby?

    - by Gishu
    The problem is very simple. An object needs to notify some events that might be of interest to observers. When I sat to validate a design that I cooked up now in Ruby just to validate it.. I find myself stumped as to how to implement the object events. In .Net this would be a one-liner.. .Net also does handler method signature verification,etc. e.g. // Object with events public delegate void HandlerSignature(int a); public event HandlerSignature MyEvent; public event HandlerSignature AnotherCriticalEvent; // Client MyObject.MyEvent += new HandlerSignature(MyHandlerMethod); // MyHandlerMethod has same signature as delegate Is there an EventDispatcher module or something that I am missing that I can strap on to a Ruby class ? Hoping for an answer that plays along with Ruby's principle of least surprise. An event would be the name of the event plus a queue of [observer, methodName] objects that need to be invoked when the event takes place.

  • Bubble sort algorithm implementations (Haskell vs. C)

    - by kingping
    Hello. I have written 2 implementation of bubble sort algorithm in C and Haskell. Haskell implementation: module Main where main = do contents <- readFile "./data" print "Data loaded. Sorting.." let newcontents = bubblesort contents writeFile "./data_new_ghc" newcontents print "Sorting done" bubblesort list = sort list [] False rev = reverse -- separated. To see rev2 = reverse -- who calls the routine sort (x1:x2:xs) acc _ | x1 > x2 = sort (x1:xs) (x2:acc) True sort (x1:xs) acc flag = sort xs (x1:acc) flag sort [] acc True = sort (rev acc) [] False sort _ acc _ = rev2 acc I've compared these two implementations having run both on file with size of 20 KiB. C implementation took about a second, Haskell — about 1 min 10 sec. I have also profiled the Haskell application: Compile for profiling: C:\Temp ghc -prof -auto-all -O --make Main Profile: C:\Temp Main.exe +RTS -p and got these results. This is a pseudocode of the algorithm: procedure bubbleSort( A : list of sortable items ) defined as: do swapped := false for each i in 0 to length(A) - 2 inclusive do: if A[i] > A[i+1] then swap( A[i], A[i+1] ) swapped := true end if end for while swapped end procedure I wonder if it's possible to make Haskell implementation work faster without changing the algorithm (there's are actually a few tricks to make it work faster, but neither implementations have these optimizations)

  • Open source file upload with no timeout on IIS6 with ASP, ASP.NET 2.0 or PHP5

    - by Christopher Done
    I'm after a cross-platform cross-browser way of uploading files such that there is no timeout. Uploads aren't necessarily huge -- some just take a long time to upload because of the uploader's slow connection -- but the server times out anyway. I hear that there are methods to upload files in chunks so that somehow the server decides not to timeout the upload. After searching around all I can see is proprietary upload helpers and Java and Flash (SWFUpload) widgets that aren't cross-platform, don't upload in chunks, or aren't free. I'd like a way to do it in any of these platforms (ASP, ASP.NET 2.0 or PHP5), though I am not very clued up on all this .NET class/controller/project/module/visual studio/compile/etc stuff, so some kind of runnable complete project that runs on .NET 2.0 would be helpful. PHP and ASP I can assume will be more straight-forward. Unless I am completely missing something, which I suspect/hope I am, reasonable web uploads are bloody hard work in any language or platform. So my question is: how can I perform web browser uploads, cross-platform, so that they don't timeout, using free software? Is it possible at all?

  • Using perl to split a line that may contain whitespace

    - by Tommy Fisk
    Okay, so I'm using perl to read in a file that contains some general configuration data. This data is organized into headers based on what they mean. An example follows: [vars] # This is how we define a variable! $var = 10; $str = "Hello thar!"; # This section contains flags which can be used to modify module behavior # All modules read this file and if they understand any of the flags, use them [flags] Verbose = true; # Notice the errant whitespace! [path] WinPath = default; # Keyword which loads the standard PATH as defined by the operating system. Append with additonal values. LinuxPath = default; Goal: Using the first line as an example "$var = 10;", I'd like to use the split function in perl to create an array that contains the characters "$var" and "10" as elements. Using another line as an example: Verbose = true; # Should become [Verbose, true] aka no whitespace is present This is needed because I will be outputting these values to a new file (which a different piece of C++ code will read) to instantiate dictionary objects. Just to give you a little taste of what it might look like (just making it up as I go along): define new dictionary name: [flags] # Start defining keys => values new key name: Verbose new value val: 10 # End dictionary Oh, and here is the code I currently have along with what it is doing (incorrectly): sub makeref($) { my @line = (split (/=/)); # Produces ["Verbose", " true"]; }

  • How to determine subprocess.Popen() failed when shell=True

  • How to implement a python REPL that nicely handles asynchronous output?

    - by andy
    I have a Python-based app that can accept a few commands in a simple read-eval-print-loop. I'm using raw_input('> ') to get the input. On Unix-based systems, I also import readline to make things behave a little better. All this is working fine. The problem is that there are asynchronous events coming in, and I'd like to print output as soon as they happen. Unfortunately, this makes things look ugly. The " " string doesn't show up again after the output, and if the user is halfway through typing something, it chops their text in half. It should probably redraw the user's text-in-progress after printing something. This seems like it must be a solved problem. What's the proper way to do this? Also note that some of my users are Windows-based. TIA Edit: The accepted answer works under Unixy platforms (when the readline module is available), but if anyone knows how to make this work under Windows, it would be much appreciated!

  • manage.py runserver throws an ImportError with my appname, MacPorts issue on OSX?

    - by christmasgorilla
    I've been developing a Django app for weeks locally on OSX 10.6.3. Recently, I rebooted my machine and went to start my development environment up. Here's the error: cm:myApp cm$ python manage.py runserver Traceback (most recent call last): File "manage.py", line 11, in execute_manager(settings) File "/Library/Python/2.6/site-packages/django/core/management/init.py", line 360, in execute_manager setup_environ(settings_mod) File "/Library/Python/2.6/site-packages/django/core/management/init.py", line 343, in setup_environ project_module = import_module(project_name) File "/Library/Python/2.6/site-packages/django/utils/importlib.py", line 35, in import_module import(name) ImportError: No module named myapp I'm pretty new to Django / Python. Digging around, it's possible that this might be due to MacPorts. Initially, I had a rough time getting Django up and running and I no longer remember if I'm using the Django from a MacPorts install or from easy_install. How do I tell? (I'd prefer not to reinstall everything). Also, why is the camel casing in my app name gone in the ImportError message? When I search for "myapp" in my django project, I don't find it without camelcase anywhere. And what causes MacPorts to work for a while but then break? As a few other details, from settings.py: INSTALLED_APPS = ( 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'django.contrib.admin', 'south', 'registration', 'pypaypal', 'notifier', 'myApp.batches', )

  • WPF and Prism View Overlay

    - by Zaheer
    Hi, I need some help with overlaying views using the prism framework.Its a little more complexed than that so let me explain.I could be over-thinking this as well :D i have shell (wpf window) and i have 2 views(A & B - both usercontrols) in a module. when the shell loads it loads view A. On view A i have a button to "popup" view B for some user input. so naturally i would think to some sort of modal window/control, maybe even a popup. however the problem i face with the popup is that when i move the shell the popup remains fixed and it doesnt block events in view A. I've tried disabling view A to stop events being fired and i've also tried to use a to get the view B move with the shell. Only the canvas works but i now need a way to block it tho'. Is there anyway i can overlay a view on top of another view with prism? or how does everyone else create modal popups with prism & wpf? any advise or pointers would be greatly appreciated.

  • Troubles with PyDev and external libraries in OS X

    - by Davide Gualano
    I've successfully installed the latest version of PyDev in my Eclipse (3.5.1) under OS X 10.6.3, with python 2.6.1 I have troubles in making the libraries I have installed work.

  • Tailing 'Jobs' with Perl under mod_perl

    - by Matthew
    Hi everyone, I've got this project running under mod_perl shows some information on a host. On this page is a text box with a dropdown that allows users to ping/nslookup/traceroute the host. The output is shown in the text box like a tail -f. It works great under CGI. When the user requests a ping it would make an AJAX call to the server, where it essentially starts the ping with the output going to a temp file. Then subsequent ajax calls would 'tail' the file so that the output was updated until the ping finished. Once the job finished, the temp file would be removed. However, under mod_perl no matter what I do I can's stop it from creating zombie processes. I've tried everything, double forking, using IPC::Run etc. In the end, system calls are not encouraged under mod_perl. So my question is, maybe there's a better way to do this? Is there a CPAN module available for creating command line jobs and tailing output that will work under mod_perl? I'm just looking for some suggestions. I know I could probably create some sort of 'job' daemon that I signal with details and get updates from. It would run the commands and keep track of their status etc. But is there a simpler way? Thanks in advance.

  • shared memory STL maps

    - by user306963
    Hello, I am writing an Apache module in C++. I need to store the common data that all childs need to read as a portion of shared memory. Structure is kind of map of vectors, so I want to use STL map and vectors for it. I have written a shared allocator and a shared manager for the purpose, they work fine for vectors but not for maps, below is the example: typedef vector<CustomersData, SharedAllocator<CustomersData> > CustomerVector; CustomerVector spData; //this one works fine typedef SharedAllocator< pair< const int, CustomerVector > > PairAllocator; typedef map< int, CustomerVector, less<int>, PairAllocator > SharedMap; SharedMap spIndex; //this one doesn't work I get compile time errors when I try to use the second object (spIndex), which are someting like: ../SpatialIndex.h:97: error: '((SpatialIndex*)this)-SpatialIndex::spIndex' does not have class type It looks like the compiler cannot determine a type for SharedMap template type, which is strange in my opinion, it seems to me that all the template parameters have been specified. Can you help? Thanks Benvenuto

  • Perl, share package variable without Export

    - by Mike
    I'm creating a group of Perl scripts, and I would like to have one package store a group of constants. I don't want to export them using Exporter because there will be quite a few and I don't want to pollute the namespace. Since there will be so many, I don't want to require the user to be forced to manually specify which they will be using. I think the best way to just use the packagename::var syntax, however it doesn't seem to be working as I expect it to. I illustrate this problem in the below code This is settings.pm, the module that will hold the global settings #!/usr/bin/perl #settings.pm use strict; use warnings; package settings; our $foo="hello world"; 1; Below is the main script #!/usr/bin/perl #script.pl use strict; use warnings; use settings; print settings::$foo; It gives this error message instead or printing hello world Bad name after settings:: at ./script.pl line 8.

  • What's the best way to develop a debugging window for an ajax ASP.Net MVC application

    - by KallDrexx
    While developing my ASP.NET MVC, I have started to see the need for a debugging console window to assist in figuring out what is going right and wrong in my code. I read the last few chapters of the Pro Asp.net MVC book, and the author details how to use http modules to show page load/creation times and linq to sql query logs, both of which I definitely want to be able to see. However, since I am loading a lot of small sections of my page individually with ajax I don't want the debug information right there in the middle of my screen. So the idea I came up with was to have a separate browser window (open-able by a link or some javascript) with a console log, that can contain logged entries both from javascript and from the asp.net mvc run. The former should be relatively easy, but I'm having trouble coming up with a way to log the asp.net information in ajax requests. The direction I have been thinking of going is to create an httpmodule (like the Pro MVC book does), and have that module contain some that append the javascript's log to console calls with the messages. The issue I see with this is finding a way to get the log messages from the controller's action methods to the httpmodule's methods. The only way I see to do this is with a singleton, but I'm not sure if singletons are bad practice for a stateless web application. Furthermore, it seems like if I return json with my ajax calls (instead of pure html) then that won't work at all anyways and unless there is a way to add data to an existing json structure inside the httpmodule. How does everyone else handle this type of debugging in heavily ajax applications? For reference, the javascript library I am using is jquery.

    I have a string buffer of a huge text file. I have to search a given words/phrases in the string buffer. Whats the efficient way to do it ? I tried using re module matches. But As i have a huge text corpus that i have to search through. This is taking large amount of time. Given a Dictionary of words and Phrases. I iterate through the each file, read that into string , search all the words and phrases in the dictionary and increment the count in the dictionary if the keys are found. One small optimization that we thought was to sort the dictionary of phrases/words with the max number of words to lowest. And then compare each word start position from the string buffer and compare the list of words. If one phrase is found, we don search for the other phrases (as it matched the longest phrase ,which is what we want) Can some one suggest how to go about word by word in the string buffer. (Iterate string buffer word by word) ? Also, Is there any other optimization that can be done on this ?

  • Is there a Standard or Best Practice for Perl Progams, as opposed to Perl Modules?

    - by swestrup
    I've written any number of perl modules in the past, and more than a few stand-alone perl programs, but I've never released a multi-file perl program into the wild before. I have a perl program that is almost at the beta stage and is going to be released open source. It requires a number of data files, as well as some external perl modules -- some I've written myself, and some from CPAN -- that I'll have to bundle with it so as to ensure that someone can just download my program and install it without worrying about hunting for obscure modules. So, it sounds to me like I need to write an installer to copy all the files to standard locations so that a user can easily install everything. The trouble is, I have no idea what the standard practice would be for this. I have found lots of tutorials on perl module standards, but none on perl program standards. Does anyone have any pointers to standard paths, installation proceedures, etc, for perl programs? This is going to be complicated by the fact that the program is multi-platform. I've been testing it in Linux, but its designed to work equally well in Windows.

  • Python and MySQLdb

    - by rohanbk
    I have the following query that I'm executing using a Python script (by using the MySQLdb module). conn=MySQLdb.connect (host = "localhost", user = "root",passwd = "<password>",db = "test") cursor = conn.cursor () preamble='set @radius=%s; set @o_lat=%s; set @o_lon=%s; '%(radius,latitude,longitude) query='SELECT *, 6371*1000 * acos(cos(radians(@o_lat)) * cos(radians(lat)) * cos(radians(lon) - radians(@o_lon)) + sin(radians(@o_lat)) * sin(radians(lat))) as distance FROM poi_table HAVING distance < @radius ORDER BY distance ASC LIMIT 0, 50' complete_query=preamble+query results=cursor.execute (complete_query) print results The values of radius, latitude, and longitude are not important, but they are being defined when the script executes. What bothers me is that the snippet of code above returns no results; essentially meaning that the way that the query is being executed is wonky. I executed the SQL query (including the set variables with actual values, and it returned the correct number of results). If I modify the query to just be a simple SELECT FROM query (SELECT * FROM poi_table) it returns results. What is going on here?

  • Python: Networked IDLE/Redo IDLE front-end while using the same back-end?

    - by Rosarch
    Is there any existing web app that lets multiple users work with an interactive IDLE type session at once? Something like: IDLE 2.6.4 Morgan: >>> letters = list("abcdefg") Morgan: >>> # now, how would you iterate over letters? Jack: >>> for char in letters: print "char %s" % char char a char b char c char d char e char f char g Morgan: >>> # nice nice If not, I would like to create one. Is there some module I can use that simulates an interactive session? I'd want an interface like this: def class InteractiveSession(): ''' An interactive Python session ''' def putLine(line): ''' Evaluates line ''' pass def outputLines(): ''' A list of all lines that have been output by the session ''' pass def currentVars(): ''' A dictionary of currently defined variables and their values ''' pass (Although that last function would be more of an extra feature.) To formulate my problem another way: I'd like to create a new front end for IDLE. How can I do this? UPDATE: Or maybe I can simulate IDLE through eval()? UPDATE 2: What if I did something like this: I already have a simple GAE Python chat app set up, that allows users to sign in, make chat rooms, and chat with each other. Instead of just saving incoming messages to the datastore, I could do something like this: def putLine(line, user, chat_room): ''' Evaluates line for the session used by chat_room ''' # get the interactive session for this chat room curr_vars = InteractiveSession.objects.where("chatRoom = %s" % chat_room).get() result = eval(prepared_line, curr_vars.state, {}) curr_vars.state = curr_globals curr_vars.lines.append((user, line)) if result: curr_vars.lines.append(('SELF', result.__str__())) curr_vars.put() The InteractiveSession model: def class InteractiveSession(db.Model): # a dictionary mapping variables to values # it looks like GAE doesn't actually have a dictionary field, so what would be best to use here? state = db.DictionaryProperty() # a transcript of the session # # a list of tuples of the form (user, line_entered) # # looks something like: # # [('Morgan', '# hello'), # ('Jack', 'x = []'), # ('Morgan', 'x.append(1)'), # ('Jack', 'x'), # ('SELF', '[1]')] lines = db.ListProperty() Could this work, or am I way off/this approach is infeasible/I'm duplicating work when I should use something already built?

  • Binary search in a sorted (memory-mapped ?) file in Java

    - by sds
    I am struggling to port a Perl program to Java, and learning Java as I go. A central component of the original program is a Perl module that does string prefix lookups in a +500 GB sorted text file using binary search (essentially, "seek" to a byte offset in the middle of the file, backtrack to nearest newline, compare line prefix with the search string, "seek" to half/double that byte offset, repeat until found...) I have experimented with several database solutions but found that nothing beats this in sheer lookup speed with data sets of this size. Do you know of any existing Java library that implements such functionality? Failing that, could you point me to some idiomatic example code that does random access reads in text files? Alternatively, I am not familiar with the new (?) Java I/O libraries but would it be an option to memory-map the 500 GB text file (I'm on a 64-bit machine with memory to spare) and do binary search on the memory-mapped byte array? I would be very interested to hear any experiences you have to share about this and similar problems.

  • How can I inject multiple repositories in a NServicebus message handler?

    - by Paco
    I use the following: public interface IRepository<T> { void Add(T entity); } public class Repository<T> { private readonly ISession session; public Repository(ISession session) { this.session = session; } public void Add(T entity) { session.Save(entity); } } public class SomeHandler : IHandleMessages<SomeMessage> { private readonly IRepository<EntityA> aRepository; private readonly IRepository<EntityB> bRepository; public SomeHandler(IRepository<EntityA> aRepository, IRepository<EntityB> bRepository) { this.aRepository = aRepository; this.bRepository = bRepository; } public void Handle(SomeMessage message) { aRepository.Add(new A(message.Property); bRepository.Add(new B(message.Property); } } public class MessageEndPoint : IConfigureThisEndpoint, AsA_Server, IWantCustomInitialization { public void Init() { ObjectFactory.Configure(config => { config.For<ISession>() .CacheBy(InstanceScope.ThreadLocal) .TheDefault.Is.ConstructedBy(ctx => ctx.GetInstance<ISessionFactory>().OpenSession()); config.ForRequestedType(typeof(IRepository<>)) .TheDefaultIsConcreteType(typeof(Repository<>)); } } My problem with the threadlocal storage is, is that the same session is used during the whole application thread. I discovered this when I saw the first level cache wasn't cleared. What I want is using a new session instance, before each call to IHandleMessages<.Handle. How can I do this with structuremap? Do I have to create a message module?
