  • Log4j show package name

    - by Stephane Grenier
    Right now for my ConversionPattern I have: log4j.appender.A1.layout.ConversionPattern=%d{yyyy MMM dd HH:mm:ss,SSS} %5p [%t] (%F:%L) - %m%n What I'd like to do is also include the full package name with the class (%F:%L) but I can't find any config to do so in the docs. I do understand that this will be slower, but it's only for debugging and not when the system will be in production.

  • SQL Server 2000: Why is this query w/ variables so slow vs w/o variables?

    - by William DiStefano
    I can't figure out why this query would be so slow with variables versus without them. I read some where that I need to enable "Dynamic Parameters" but I cannot find where to do this. DECLARE @BeginDate AS DATETIME ,@EndDate AS DATETIME SELECT @BeginDate = '2010-05-20' ,@EndDate = '2010-05-25' -- Fix date range to include time values SET @BeginDate = CONVERT(VARCHAR(10), ISNULL(@BeginDate, '01/01/1990'), 101) + ' 00:00' SET @EndDate = CONVERT(VARCHAR(10), ISNULL(@EndDate, '12/31/2099'), 101) + ' 23:59' SELECT * FROM claim c WHERE (c.Received_Date BETWEEN @BeginDate AND @EndDate) --this is much slower --(c.Received_Date BETWEEN '2010-05-20' AND '2010-05-25') --this is much faster

  • How to test 500.html in (django) development env?

    - by lud0h
    I am using Django for a project and is already in production. In the production environment 500.html is rendered whenever a server error occurs. How do I test the rendering of 500.html in dev environment? Or how do I render 500.html in dev, if I turn-off debug I still get the errors and not 500.html background: I include some page elements based on a page and some are missing when 500.html is called and want to debug it in dev environment.

  • Reading and writing C++ vector to a file

    - by JB
    For some graphics work I need to read in a large amount of data as quickly as possible and would ideally like to directly read and write the data structures to disk. Basically I have a load of 3d models in various file formats which take too long to load so I want to write them out in their "prepared" format as a cache that will load much faster on subsequent runs of the program. Is it safe to do it like this? My worries are around directly reading into the data of the vector? I've removed error checking, hard coded 4 as the size of the int and so on so that i can give a short working example, I know it's bad code, my question really is if it is safe in c++ to read a whole array of structures directly into a vector like this? I believe it to be so, but c++ has so many traps and undefined behavour when you start going low level and dealing directly with raw memory like this. I realise that number formats and sizes may change across platforms and compilers but this will only even be read and written by the same compiler program to cache data that may be needed on a later run of the same program. #include <fstream> #include <vector> using namespace std; struct Vertex { float x, y, z; }; typedef vector<Vertex> VertexList; int main() { // Create a list for testing VertexList list; Vertex v1 = {1.0f, 2.0f, 3.0f}; list.push_back(v1); Vertex v2 = {2.0f, 100.0f, 3.0f}; list.push_back(v2); Vertex v3 = {3.0f, 200.0f, 3.0f}; list.push_back(v3); Vertex v4 = {4.0f, 300.0f, 3.0f}; list.push_back(v4); // Write out a list to a disk file ofstream os ("data.dat", ios::binary); int size1 = list.size(); os.write((const char*)&size1, 4); os.write((const char*)&list[0], size1 * sizeof(Vertex)); os.close(); // Read it back in VertexList list2; ifstream is("data.dat", ios::binary); int size2; is.read((char*)&size2, 4); list2.resize(size2); // Is it safe to read a whole array of structures directly into the vector? is.read((char*)&list2[0], size2 * sizeof(Vertex)); }

  • getline() sets failbit and skips last line

    - by Thanatos
    I'm using std::getline() to enumerate through the lines in a file, and it's mostly working. It's left me curious however - std::getline() is skipping the very last line in my file, but only if it's blank. Using this minimal example: #include <iostream> #include <string> int main() { std::string line; while(std::getline(std::cin, line)) std::cout << "Line: “" << line << "”\n"; return 0; } If I feed it this: Line A Line B Line C I get those lines back at me. But this: Line A Line B Line C [* line is present but blank, ie, the file end is: "...B\nLine C\n" *] (I unfortunately can't have a blank line in SO's little code box thing...) So, first file has three lines ( ["Line A", "Line B", "Line C"] ), second file has four ( ["Line A", "Line B", "Line C", ""] ) This to me seems wrong - I have a four line file, and enumerating it with getline() leaves me with 3. What's really got me scratching my head is that this is exactly what the standard says it should do. (21.3.7.9) Even Python has similar behaviour (but it gives me the newlines too - C++ chops them off.) Is this some weird thing where C++ is expected lines to be terminated, and not separated by '\n', and I'm feeding it differently? Edit Clearly, I need to expand a bit here. I've met up with two philosophies of determining what a "line" in a file is: Lines are terminated by newlines - Dominant in systems such as Linux, and editors like vim. Possible to have a slightly "odd" file by not having a final '\n' (a "noeol" in vim). Impossible to have a blank line at the end of a file. Lines are separated by newlines - Dominant in just about every Windows editor I've ever come across. Every file is valid, and it's possible to have the last line be blank. Of course, YMMV as to what a newline is. I've always treated these as two completely different schools of thought. One earlier point I tried to make was to ask if the C++ standard was explicitly or merely implicitly following the first. (Curiously, where is Mac? terminated or separated?)

Below is a the publisher.php <?php require_once('../php-amqplib/amqp.inc'); include('../config.php'); $conn = new AMQPConnection(HOST, PORT, USER, PASS, VHOST); $channel = $conn->channel(); $channel->exchange_declare('upload-pictures','direct', false, true, false); $metadata = json_encode(array( 'image_id' => $argv[1], 'user_id' => $argv[2], 'image_path' => $argv[3] )); $msg = new AMQPMessage($metadata, array('content_type' => 'text/plain','delivery_mode' => 2)); $channel->basic_publish($msg, 'upload-pictures'); $channel->close(); $conn->close(); ?> consumer.php <?php require_once('../php-amqplib/amqp.inc'); include('../config.php'); $conn = new AMQPConnection(HOST, PORT, USER, PASS,VHOST); $channel = $conn->channel(); $queue = 'add-points'; $consumer_tag = 'consumer'; $channel->exchange_declare('upload-pictures','direct', false, true, false); $channel->queue_declare('add-points',false, true, false, false); $channel->queue_bind('add-points', 'upload-pictures'); $consumer = function($msg){}; $channel->basic_consume($queue,$consumer_tag,false,false,false,false,$consumer); ?> according to the example provided in the rabbitmq manual, i need to run consumer(php consumer.php) first in one terminal and the publisher (php publisher.php 1 2 file/path.png) in another terminal, i will get a "Adding points to user: 2" message in the consumer terminal. iam not getting this message at all. can you suggest where iam going wrong

  • Regular Expression Question

    - by zyq524
    I'm trying to use regular expression to extract the comments in the heading of a file. For example, the source code may look like: //This is an example file. //Please help me. #include "test.h" int main() //main function { ... } What I want to extract from the code are the first two lines, i.e. //This is an example file. //Please help me. Any idea?

  • How to get SQL Profiler to monitor trigger execution

    - by firedfly
    I have a trace setup for SQL Server Profiler to monitor SQL that is executed on a database. I recently discovered that trigger execution is not included in the trace. After looking through available events for a trace, I do not see any that look like they would include trigger execution. Does anyone know how to setup a trace to monitor the execution of triggers?

  • Best PHP timezone list

    - by jimbo
    I have looked over the PHP list of supported timezones, but the whole list is a little long to include in a drop-down menu, for the user to select his or her timezone. Is there a list with the main city/area on that can be used? My geography is terrible and add that to not knowing all the area and which timezone they fall into it could be a long day to construct the list my self! Thanks in advance

  • Parse lines of integers in C

    - by Jérôme
    This is a classical problem, but I can not find a simple solution. I have an input file like: 1 3 9 13 23 25 34 36 38 40 52 54 59 2 3 9 14 23 26 34 36 39 40 52 55 59 63 67 76 85 86 90 93 99 108 114 2 4 9 15 23 27 34 36 63 67 76 85 86 90 93 99 108 115 1 25 34 36 38 41 52 54 59 63 67 76 85 86 90 93 98 107 113 2 3 9 16 24 28 2 3 10 14 23 26 34 36 39 41 52 55 59 63 67 76 Lines of different number of integers separated by a space. I would like to parse them in an array, and separate each line with a marker, let say -1. The difficulty is that I must handle integers and line returns. Here my existing code, it loops upon the scanf loop (because scanf can not begin at a given position). #include <stdio.h> #include <stdlib.h> int main(int argc, char **argv) { if (argc != 4) { fprintf(stderr, "Usage: %s <data file> <nb transactions> <nb items>\n", argv[0]); return 1; } FILE * file; file = fopen (argv[1],"r"); if (file==NULL) { fprintf(stderr, "Error: can not open %s\n", argv[1]); fclose(file); return 1; } int nb_trans = atoi(argv[2]); int nb_items = atoi(argv[3]); int *bdd = malloc(sizeof(int) * (nb_trans + nb_items)); char line[1024]; int i = 0; while ( fgets(line, 1024, file) ) { int item; while ( sscanf (line, "%d ", &item )){ printf("%s %d %d\n", line, i, item); bdd[i++] = item; } bdd[i++] = -1; } for ( i = 0; i < nb_trans + nb_items; i++ ) { printf("%d ", bdd[i]); } printf("\n"); }

  • Internationalization of static pages with Rails

    - by Gavin
    I feel like I'm missing something really simple and I keep spinning my wheels on this problem. I currently have internationalization working throughout my app. The translations work and the routes work perfectly. At least, most of the site works with the exception of the routes to my two static pages, my "About" and "FAQ" pages. Every other link throughout the app points to the proper localized route. For example if I select "french" as my language, links point to the appropriate "(/:locale)/controller(.:format)." However, despite the changes I make throughout the app my links for the "About" and "FAQ" refuse to point to "../fr/static/about" and always point to "/static/about." To make matters stranger, when I run rake routes I see: "GET (/:locale)/static/:permalink(.:format) pages#show {:locale=/en|fr/}" and when I manually type in "../fr/static/about" the page translates perfectly. My Routes file: devise_for :users scope "(:locale)", :locale => /en|fr/ do get 'static/:permalink', :controller => 'pages', :action => 'show' resources :places, only: [:index, :show, :destroy] resources :homes, only: [:index, :show] match '/:locale' => 'places#index' get '/'=>'places#index',:as=>"root" end My ApplicationController: before_filter :set_locale def set_locale I18n.locale=params[:locale]||I18n.default_locale end def default_url_options(options={}) logger.debug "default_url_options is passed options: #{options.inspect}\n" { :locale => I18n.locale } end and My Pages Controller: class PagesController < ApplicationController before_filter :validate_page PAGES = ['about_us', 'faq'] def show render params[:permalink] end def validate_page redirect_to :status => 404 unless PAGES.include?(params[:permalink]) end end I'd be very grateful for any help ... it's just been one of those days. Edit: Thanks to Terry for jogging me to include views. <div class="container-fluid nav-collapse"> <ul class="nav"> <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown"><%= t(:'navbar.about') %><b class="caret"></b></a> <ul class="dropdown-menu"> <li><%=link_to t(:'navbar.about_us'), "/static/about_us"%></li> <li><%=link_to t(:'navbar.faq'), "/static/faq"%></li> <li><%=link_to t(:'navbar.blog'), '#' %></li> </ul> </li>

  • HTML tags in mysql text field

    - by paracaudex
    I'm creating a database with what I anticipate will be a long (perhaps several paragraphs for some tuples) attribute. I'm assigning it text instead of varchar. I have two questions: Should I give a maximum value for the text field? Is this necessary? Is it useful? Since the contents of this field will be displayed on a website in HTML, do I need to include paragraph tags for paragraph formatting when I enter records into mysql?

  • Some clarification on rvalue references

    - by Dennis Zickefoose
    First: where are std::move and std::forward defined? I know what they do, but I can't find proof that any standard header is required to include them. In gcc44 sometimes std::move is available, and sometimes its not, so a definitive include directive would be useful. When implementing move semantics, the source is presumably left in an undefined state. Should this state necessarily be a valid state for the object? Obviously, you need to be able to call the object's destructor, and be able to assign to it by whatever means the class exposes. But should other operations be valid? I suppose what I'm asking is, if your class guarantees certain invariants, should you strive to enforce those invariants when the user has said they don't care about them anymore? Next: when you don't care about move semantics, are there any limitations that would cause a non-const reference to be preferred over an rvalue reference when dealing with function parameters? void function(T&); over void function(T&&); From a caller's perspective, being able to pass functions temporary values is occasionally useful, so it seems as though one should grant that option whenever it is feasible to do so. And rvalue references are themselves lvalues, so you can't inadvertently call a move-constructor instead of a copy-constructor, or something like that. I don't see a downside, but I'm sure there is one. Which brings me to my final question. You still can not bind temporaries to non-const references. But you can bind them to non-const rvalue references. And you can then pass along that reference as a non-const reference in another function. void function1(int& r) { r++; } void function2(int&& r) { function1(r); } int main() { function1(5); //bad function2(5); //good } Besides the fact that it doesn't do anything, is there anything wrong with that code? My gut says of course not, since changing rvalue references is kind of the whole point to their existence. And if the passed value is legitimately const, the compiler will catch it and yell at you. But by all appearances, this is a runaround of a mechanism that was presumably put in place for a reason, so I'd just like confirmation that I'm not doing anything foolish.
