  • rabbitmq-erlang-client, using rebar friendly pkg, works on dev env fails on rebar release

    - by lfurrea
    I am successfully using the rebar-friendly package of rabbitmq-erlang-client for a simple Hello World rebarized and OTP "compliant" app and things work fine on the dev environment. I am able to fire up an erl console and do my application:start(helloworld). and connect to the broker, open up a channel and communicate to queues. However, then I proceed to do rebar generate and it builds up the release just fine, but when I try to fire up from the self contained release package then things suddenly explode. I know rebar releases are known to be an obscure art, but I would like to know what are my options as far as deployment for an app using the rabbitmq-erlang-client. Below you will find the output of the console on the crash: =INFO REPORT==== 18-Dec-2012::16:41:35 === application: session_record exited: {{{badmatch, {error, {'EXIT', {undef, [{amqp_connection_sup,start_link, [{amqp_params_network,<<"guest">>,<<"guest">>,<<"/">>, "127.0.0.1",5672,0,0,0,infinity,none, [#Fun<amqp_auth_mechanisms.plain.3>, #Fun<amqp_auth_mechanisms.amqplain.3>], [],[]}], []}, {supervisor2,do_start_child_i,3, [{file,"src/supervisor2.erl"},{line,391}]}, {supervisor2,handle_call,3, [{file,"src/supervisor2.erl"},{line,413}]}, {gen_server,handle_msg,5, [{file,"gen_server.erl"},{line,588}]}, {proc_lib,init_p_do_apply,3, [{file,"proc_lib.erl"},{line,227}]}]}}}}, [{amqp_connection,start,1, [{file,"src/amqp_connection.erl"},{line,164}]}, {hello_qp,start_link,0,[{file,"src/hello_qp.erl"},{line,10}]}, {session_record_sup,init,1, [{file,"src/session_record_sup.erl"},{line,55}]}, {supervisor_bridge,init,1, [{file,"supervisor_bridge.erl"},{line,79}]}, {gen_server,init_it,6,[{file,"gen_server.erl"},{line,304}]}, {proc_lib,init_p_do_apply,3, [{file,"proc_lib.erl"},{line,227}]}]}, {session_record_app,start,[normal,[]]}} type: permanent

  • How to concatenate all commit messages from subversion into one text file with no metadata?

    - by user144182
    I would like to take all the commit messages in my subversion log and just concatenate them into one text file. Each commit message has this format: - r1 message - r1 message - r1 message What I would like is something like: - r1 message - r1 message - r2 message - r2 message - r3 message [...] - r1000 message Update I thought the above was clear, but what I don't want in the log is this type of info: r2130 | user| 2010-03-19 10:36:13 -0400 (Fri, 19 Mar 2010) | 1 line No meta data, I simply want the commit messages.

  • Elegant way for a recursive C++ template to do something different with the leaf class?

    - by Costas
    I have a C++ class template that makes an Array of pointers. This also gets typedefed to make Arrays of Arrays and so on: typedef Array<Elem> ElemArray; typedef Array<ElemArray> ElemArrayArray; typedef Array<ElemArrayArray> ElemArrayArrayArray; I would like to be able to set one leaf node from another by copying the pointer so they both refer to the same Elem. But I also want to be able to set one Array (or Array of Arrays etc) from another. In this case I don't want to copy the pointers, I want to keep the arrays seperate and descend into each one until I get to the leaf node, at where I finally copy the pointers. I have code that does this (below). When you set something in an Array it calls a CopyIn method to do the copying. But because this is templated it also has to call the CopyIn method on the leaf class, which means I have to add a dummy method to every leaf class that just returns false. I have also tried adding a flag to the template to tell it whether it contains Arrays or not, and so whether to call the CopyIn method. This works fine - the CopyIn method of the leaf nodes never gets called, but it still has to be there for the compile to work! Is there a better way to do this? #include <stdio.h> class Elem { public: Elem(int v) : mI(v) {} void Print() { printf("%d\n",mI); } bool CopyIn(Elem *v) { return false; } int mI; }; template < typename T > class Array { public: Array(int size) : mB(0), mN(size) { mB = new T* [size]; for (int i=0; i<mN; i++) mB[i] = new T(mN); } ~Array() { for (int i=0; i<mN; i++) delete mB[i]; delete [] mB; } T* Get(int i) { return mB[i]; } void Set(int i, T* v) { if (! mB[i]->CopyIn(v) ) { // its not an array, so copy the pointer mB[i] = v; } } bool CopyIn(Array<T>* v) { for (int i=0; i<mN; i++) { if (v && i < v->mN ) { if ( ! mB[i]->CopyIn( v->mB[i] )) { // its not an array, so copy the pointer mB[i] = v->mB[i]; } } else { mB[i] = 0; } } return true; // we did the copy, no need to copy pointer } void Print() { for (int i=0; i<mN; i++) { printf("[%d] ",i); mB[i]->Print(); } } private: T **mB; int mN; }; typedef Array<Elem> ElemArray; typedef Array<ElemArray> ElemArrayArray; typedef Array<ElemArrayArray> ElemArrayArrayArray; int main () { ElemArrayArrayArray* a = new ElemArrayArrayArray(2); ElemArrayArrayArray* b = new ElemArrayArrayArray(3); // In this case I need to copy the pointer to the Elem into the ElemArrayArray a->Get(0)->Get(0)->Set(0, b->Get(0)->Get(0)->Get(0)); // in this case I need go down through a and b until I get the to Elems // so I can copy the pointers a->Set(1,b->Get(2)); b->Get(0)->Get(0)->Get(0)->mI = 42; // this will also set a[0,0,0] b->Get(2)->Get(1)->Get(1)->mI = 96; // this will also set a[1,1,1] // should be 42,2, 2,2, 3,3, 3,96 a->Print(); }

  • How to load image data from resource bitmap file for directshow filter ?

    - by Forrest
    I need put one bitmap image to my directshow filter. Then user can use this bitmap image and do not care where is it. First, I import this bitmap file into resource bundle, and get one IDB_BITMAP1. Then, I need to read this IDB_BITMAP1 using opencv cvLoadImage or some windows image API to load this image into buffer. So question is how to do this ? Or is that possible ? Thanks

  • Make Excel Defined Names within a worksheet to be global

    - by idazuwaika
    Hi, I wrote Powershell script to copy a worksheet from a workbook A to another workbook B. The worksheet contains define names for ranges within that sheet. Originally, the defined names are global in workbook A, ie. can be referenced from any worksheets within workbook A. But now, after copy to worksheet B, the defined names are limited to that worksheet only. How to I programmatically (via Powershell script preferably) make all those named range global i.e. can be referenced from all worksheets within workbook B. Some codes for clarity. #Script to update SOP from 5.1 to 5.2 $missing = [System.Type]::missing #Open files $excel = New-Object -Com Excel.Application $excel.Visible = $False $excel.DisplayAlerts = $False $newTemplate = "C:\WorkbookA.xls" $wbTemplate = $excel.Workbooks.Open($newTemplate) $oldSop = "C:\WorkbookB.xls" $wbOldSop = $excel.Workbooks.Open($oldSop) #Delete 'DATA' worksheet from old file $wsOldData = $wbOldSop.Worksheets.Item("DATA") $wsOldData.Delete() #Copy new 'DATA' worksheet to old file $wbTemplate.Worksheets.Item("DATA").Copy($missing,$wbOldSop.Worksheets.Item("STATUS")) #Save $wbOldSop.Save() $wbOldSop.Close() #Quit Excel $excel.Quit()

  • OpenGL Shader Compile Error

    - by Tomas Cokis
    I'm having a bit of a problem with my code for compiling shaders, namely they both register as failed compiles and no log is received. This is the shader compiling code: /* Make the shader */ Uint size; GLchar* file; loadFileRaw(filePath, file, &size); const char * pFile = file; const GLint pSize = size; newCashe.shader = glCreateShader(shaderType); glShaderSource(newCashe.shader, 1, &pFile, &pSize); glCompileShader(newCashe.shader); GLint shaderCompiled; glGetShaderiv(newCashe.shader, GL_COMPILE_STATUS, &shaderCompiled); if(shaderCompiled == GL_FALSE) { ReportFiler->makeReport("ShaderCasher.cpp", "loadShader()", "Shader did not compile", "The shader " + filePath + " failed to compile, reporting the error - " + OpenGLServices::getShaderLog(newCashe.shader)); } And these are the support functions: bool loadFileRaw(string fileName, char* data, Uint* size) { if (fileName != "") { FILE *file = fopen(fileName.c_str(), "rt"); if (file != NULL) { fseek(file, 0, SEEK_END); *size = ftell(file); rewind(file); if (*size > 0) { data = (char*)malloc(sizeof(char) * (*size + 1)); *size = fread(data, sizeof(char), *size, file); data[*size] = '\0'; } fclose(file); } } return data; } string OpenGLServices::getShaderLog(GLuint obj) { int infologLength = 0; int charsWritten = 0; char *infoLog; glGetShaderiv(obj, GL_INFO_LOG_LENGTH,&infologLength); if (infologLength > 0) { infoLog = (char *)malloc(infologLength); glGetShaderInfoLog(obj, infologLength, &charsWritten, infoLog); string log = infoLog; free(infoLog); return log; } return "<Blank Log>"; } and the shaders I'm loading: void main(void) { gl_FragColor = vec4(1.0, 0.0, 0.0, 1.0); } void main(void) { gl_Position = ftransform(); } In short I get From: ShaderCasher.cpp, In: loadShader(), Subject: Shader did not compile Message: The shader Data/Shaders/Standard/standard.vs failed to compile, reporting the error - <Blank Log> for every shader I compile I've tried replacing the file reading with just a hard coded string but I get the same error so there must be something wrong with how I'm compiling them. I have run and compiled example programs with shaders, so I doubt my drivers are the issue, but in any case I'm on a Nvidia 8600m GT. Can anyone help?

  • How do I force the download of a file which link is inside a GridView?

    - by murderdoll
    I have a Gridview that shows a list of files previously uploaded to the server with a HyperLink control to be able to download it, I need to force a download every time the user clicks on one of the provided links, so that the file does not open directly on the browser (they are usually images). Currently I have a side-server function that forces a download, but I do not know how to assign this function to each one of the links when the user clicks on it.

  • Has Windows 7 Fixed the 255 Character File Path Limit?

    - by The Matt
    As I understand it, the limitation of 255 characters in a file path is a Windows limitation. What is the reasoning for this? If so, has this been resolved in Windows 7? In our continuous integration practices, we often have deeply nested project structures and it would be extremely useful to be able to go beyond 255 characters. Right now we are somewhat forced to structure our projects in such a way as to not hit this artificial ceiling.

  • How to use a properties file with Hudson in compilation time?

    - by Neuquino
    Hi, I have a pom.xml that uses cxf-codegen-plugin to generate a couple of WS clients. Inside the configuration of cxf-codegen-plugin, there are the WSDL locations. I would like to externalize those strings to a env.properties file. I used org.codehaus.mojo's properties-maven-plugin to look inside src/main/resources/conf/app/env.properties. How can I make Hudson to replace those properties with the apropiate host? Thanks in advance

  • Why does file have to be saved prior to running ?

    - by ldigas
    In MATLAB, why does the file have to be saved prior to running ? I often try quick snippets of code, which I could also easily run also on the Command Window line by line. So, why when I run them through the editor, I have to save them first ? Can this behaviour be changed, maybe ?

  • Any Suggestions for Opening a .asc (ASCII) file when Notepad doesn't do the trick?

    - by ajdams

Does anyone recognize this formatting or know why it may not be opening properly?

  • Is There a Better Way to Feed Different Parameters into Functions with If-Statements?

    - by FlowofSoul
    I've been teaching myself Python for a little while now, and I've never programmed before. I just wrote a basic backup program that writes out the progress of each individual file while it is copying. I wrote a function that determines buffer size so that smaller files are copied with a smaller buffer, and bigger files are copied with a bigger buffer. The way I have the code set up now doesn't seem very efficient, as there is an if loop that then leads to another if loops, creating four options, and they all just call the same function with different parameters. import os import sys def smartcopy(filestocopy, dest_path, show_progress = False): """Determines what buffer size to use with copy() Setting show_progress to True calls back display_progress()""" #filestocopy is a list of dictionaries for the files needed to be copied #dictionaries are used as the fullpath, st_mtime, and size are needed if len(filestocopy.keys()) == 0: return None #Determines average file size for which buffer to use average_size = 0 for key in filestocopy.keys(): average_size += int(filestocopy[key]['size']) average_size = average_size/len(filestocopy.keys()) #Smaller buffer for smaller files if average_size < 1024*10000: #Buffer sizes determined by informal tests on my laptop if show_progress: for key in filestocopy.keys(): #dest_path+key is the destination path, as the key is the relative path #and the dest_path is the top level folder copy(filestocopy[key]['fullpath'], dest_path+key, callback = lambda pos, total: display_progress(pos, total, key)) else: for key in filestocopy.keys(): copy(filestocopy[key]['fullpath'], dest_path+key, callback = None) #Bigger buffer for bigger files else: if show_progress: for key in filestocopy.keys(): copy(filestocopy[key]['fullpath'], dest_path+key, 1024*2600, callback = lambda pos, total: display_progress(pos, total, key)) else: for key in filestocopy.keys(): copy(filestocopy[key]['fullpath'], dest_path+key, 1024*2600) def display_progress(pos, total, filename): percent = round(float(pos)/float(total)*100,2) if percent <= 100: sys.stdout.write(filename + ' - ' + str(percent)+'% \r') else: percent = 100 sys.stdout.write(filename + ' - Completed \n') Is there a better way to accomplish what I'm doing? Sorry if the code is commented poorly or hard to follow. I didn't want to ask someone to read through all 120 lines of my poorly written code, so I just isolated the two functions. Thanks for any help.
