• KeepAlive packets over a Soap request

  - by Nycto

  I've been debugging some Soap requests we are making between two servers on the same VLAN. The app on one server is written in PHP, the app on the other is written in Java. I can control and make changes to the PHP code, but I can't affect the Java server. The PHP app forms the XML using the DOMDocument objects, then sends the request using the cURL extension. When the soap request took longer than 5 minutes to complete, it would always wait until the max timeout limit and exit with a message like this: Operation timed out after 900000 milliseconds with 0 bytes received After sniffing the packets that were being sent, it turns out that the problem was caused by a 5 minute timeout in the network that was closing what it thought was a stale connection. There were two ways to fix it: bump up the timeout in iptables, or start sending KeepAlive packets over the request. To be thorough, I would like to implement both solutions. Bumping up the timeout was easy for ops to do, but sending KeepAlive packets is turning out to be difficult. The cURL library itself supports this (see the --keepalive-time flag for the CLI app), but it doesn't appear that this has been implemented in the PHP cURL library. I even checked the source to make sure it wasn't an undocumented feature. So my question is this: How the heck can I get these packets sent? I see a few clear options, but I don't like any of them: Write a wrapper that will kick off the request by shell_execing the CLI app. This is a hack that I just don't like Update the cURL extension to support this. This is a non-option according to Ops. Open the socket myself. I know just enough to be dangerous. I also haven't seen a way to do this with fsockopen, but I could be missing something. Switch to another library. What exists that supports this? Thanks for any help you can offer.

• Python equivalent of IDL's stop and .reset

  - by Jamie

  Hi there, I'm relatively new to python but have a bit of experience using IDL. I was wondering if anyone knows if there are equivalent commands in python for IDL's stop and .reset commands. If I'm running some IDL script I wrote that I put a stop command in, essentially what it does is stop the script there and give me access to the command line in the middle of the script. So I have access to all the functions and variables that I defined before the stop command, which I find really useful for debugging. The .reset command I find extremely useful too. What it does is reset the the IDL environment (clears all variables, functions, etc.). It's as if I closed that session and opened a new one, but without having to exit and restart IDL. I find that if I'm trying to debug a script I wrote it's useful sometimes to start from scratch and not have to reset IDL (or python now). It would be useful also in python to be able to un-import any modules I had previously imported. Any help with these issues would be greatly appreciated. Cheers Related Python Drop into REPL Is it possible to go into ipython from code?

• Executable war file that starts jetty without maven

  - by twilbrand

  I'm trying to make an "executable" war file (java -jar myWarFile.war) that will start up a jetty webserver that hosts the webapp contained in the war file I executed. I found a page that described how to make what I'm looking for: http://eclipsesource.com/blogs/2009/10/02/executable-wars-with-jetty/ however, following that advice along with how I think I'm supposed to make an executable jar (war) isn't working. I have an ant task creating a war with a manifest that looks like: Manifest-Version: 1.0 Ant-Version: Apache Ant 1.7.1 Created-By: 1.5.0_18-b02 (Sun Microsystems Inc.) Main-Class: Start The contents of the war look like: > Start.class > jsp > build.jsp > META-INF > MANIFEST.MF > WEB-INF > lib > jetty-6.1.22.jar > jetty-util.6.1.22.jar When I try to execute the .war file, the error is: Exception in thread "main" java.lang.NoClassDefFoundError: org/mortbay/jetty/Handler Caused by: java.lang.ClassNotFoundException: org.mortbay.jetty.Handler at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:248) Could not find the main class: Start. Program will exit. There appears to be two errors here, one where it seems the jar files can't be found and one where the Start.class can't be found. To fix the first one, I put the jetty .jar files in the base of the war and tried again, same error. I also tried adding the WEB-INF/lib/ to the Class-path attribute of the manifest. That did not work either. Does anyone have any insight as to what I'm doing right/wrong and how I can get this executable war up and running?

• Problem compiling gnustep-gui-0.16.0 undefined reference to png_sizeof

  - by stefanB

  I'm trying to compile GNUstep on a linux box but gnustep-gui-0.16.0 package is failing. I downloaded GNUstep Startup stable 0.20.1 (http://wwwmain.gnustep.org/resources/downloads.php)and follow instructions about how to compile (./configure && make). I'm getting this error: libgnustep-gui.so: undefined reference to 'png_sizeof' I have compiled latest libpng (1.2.34) and I can see that png_sizeof is defined as macro. However, I'm not quite sure how to fix the gnustep-gui-0.16.0 build. I tried to pass the include/lib directory where libpng is installed to configure build but nothing seems to help. I have quite up to date linux box but using gcc 3.3 (upgrade is not an option - but this should not be a problem). Full error: Making all for tool set_show_service... Compiling file set_show_service.m ...

• PHP forking and mysql database connection problem

  - by user298819

  I am now trying to do forking in php. I would like to do some query and update in child process.. the problem is that whenever a child process finish, it close the connection which makes the other queries fail. The following is my sample code!! #!/usr/local/bin/php <?php set_time_limit(0); # forever program! $db = mysql_connect("server","user","pwd"); mysql_select_db("schema",$db); $sql = "query"; $res = mysql_query($sql,$db); while($rows = mysql_fetch_array($res)) { $rv = pcntl_fork(); if($rv == -1){ echo "forking failed"; }elseif($rv){ echo "parent process $rv\n"; $db = mysql_connect("192.168.8.112","zwmuser","zwmuser",true); mysql_select_db("schema",$db); }else{ echo "child process $rv\n"; $sql1 = "another query"; $res1 = mysql_query($sql1,$db); while($messages = mysql_fetch_array($res1)) { $sql2 = "update query"; mysql_query($sql2,$db); } exit(0); //it terminates both child process and mysql connection! } } ?>

• SDL_image/C++ OpenGL Program: IMG_Load() produces fuzzy images

  - by Kami

  I'm trying to load an image file and use it as a texture for a cube. I'm using SDL_image to do that. I used this image because I've found it in various file formats (tga, tif, jpg, png, bmp) The code : SDL_Surface * texture; //load an image to an SDL surface (i.e. a buffer) texture = IMG_Load("/Users/Foo/Code/xcode/test/lena.bmp"); if(texture == NULL){ printf("bad image\n"); exit(1); } //create an OpenGL texture object glGenTextures(1, &textureObjOpenGLlogo); //select the texture object you need glBindTexture(GL_TEXTURE_2D, textureObjOpenGLlogo); //define the parameters of that texture object //how the texture should wrap in s direction glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); //how the texture should wrap in t direction glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); //how the texture lookup should be interpolated when the face is smaller than the texture glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); //how the texture lookup should be interpolated when the face is bigger than the texture glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); //send the texture image to the graphic card glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, texture->w, texture->h, 0, GL_RGB, GL_UNSIGNED_BYTE, texture-> pixels); //clean the SDL surface SDL_FreeSurface(texture); The code compiles without errors or warnings ! I've tired all the files formats but this always produces that ugly result : I'm using : SDL_image 1.2.9 & SDL 1.2.14 with XCode 3.2 under 10.6.2 Does anyone knows how to fix this ?

• compiling iphone program in snow leopard wtih libsqlite3 library

  - by user360297

  Hi, I develop an iphone application which uses sqlite3 as a database. That time my OS X version was leopard. So add added libsqlite3.0.dylib to frameworks and compile without any problems it complied and with any problems I could run it on the device as well. This week I installed Snow Leopard on my Mac. Removing old Leopard version and install a fresh Snow leopard system. But my problem is now I cannot compile that program because it will give errors with sqlite3 library. I added sqlite3.0.dylib using selecting targets and then selecting file. Also tried adding selecting it from directly /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.3.sdk/usr/lib I get two different errors when I compiled to device and to simulator when compiled to device, ld: warning: in /opt/local/lib/libsqlite3.0.dylib, file is not of required architecture* When compiled to simulator, ld: warning: in /opt/local/lib/libsqlite3.0.dylib, file was built for unsupported file format which is not the architecture being linked (i386) ld: warning: in /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.3.sdk/usr/lib/libSystem.dylib, missing required architecture i386 in file ld: in /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.3.sdk/usr/lib/libobjc.A.dylib, missing required architecture i386 in file Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.2 failed with exit code 1 i also tried with adding sqlite3.dylib (, I think sqlite3.0.dylib is linked to sqlite3.dylib.) but no luck. Could any one out there give me any help. I'm really trying to get this working. Please let me if you want more details. Thank you, Waruna

• Visual Studio Macros on 64 bit fail with COM error

  - by bruce.kinchin

  I'm doing some javascript development and found a cool macro to region my code ("Using #region Directive With JavaScript Files in Visual Studio"). I used this on my 32 bit box, and it worked first time. (Visual Studio 2008 SP1, Win7) For easy of reference the macro is: Option Strict Off Option Explicit Off Imports System Imports EnvDTE Imports EnvDTE80 Imports System.Diagnostics Imports System.Collections Public Module JsMacros Sub OutlineRegions() Dim selection As EnvDTE.TextSelection = DTE.ActiveDocument.Selection Const REGION_START As String = "//#region" Const REGION_END As String = "//#endregion" DTE.ExecuteCommand("Edit.StopOutlining") selection.SelectAll() Dim text As String = selection.Text selection.StartOfDocument(True) Dim startIndex As Integer Dim endIndex As Integer Dim lastIndex As Integer = 0 Dim startRegions As Stack = New Stack() Do startIndex = text.IndexOf(REGION_START, lastIndex) endIndex = text.IndexOf(REGION_END, lastIndex) If startIndex = -1 AndAlso endIndex = -1 Then Exit Do End If If startIndex <> -1 AndAlso startIndex < endIndex Then startRegions.Push(startIndex) lastIndex = startIndex + 1 Else ' Outline region ... selection.MoveToLineAndOffset(CalcLineNumber(text, CInt(startRegions.Pop())), text.Length) selection.MoveToLineAndOffset(CalcLineNumber(text, endIndex) + 1, 1, True) selection.OutlineSection() lastIndex = endIndex + 1 End If Loop selection.StartOfDocument() End Sub Private Function CalcLineNumber(ByVal text As String, ByVal index As Integer) Dim lineNumber As Integer = 1 Dim i As Integer = 0 While i < index If text.Chars(i) = vbCr Then lineNumber += 1 i += 1 End If i += 1 End While Return lineNumber End Function End Module I then tried to use the same macro on two separate 64 bit machines (Win7 x64), identical other than the 64 bit OS version and it fails to work. Stepping through it with the Visual Studio Macros IDE, it fails the first time on the DTE.ExecuteCommand("Edit.StopOutlining") line with a COM error (Error HRESULT E_FAIL has been returned from a call to a COM component). If I attempt to run it a second time, I can run it from the Macro Editor with no issue, but not from within Visual Studio with the macro explorer 'run macro' command. I have reviewed the following articles without finding anything helpful: Stackoverflow: Visual Studio 2008 macro only works from the Macro IDE, not the Macro Explorer Recorded macro does not run; Failing on DTE.ExecuteCommand Am I missing something dumb?

• GH-Unit for unit testing Objective-C code, why am I getting linking errors?

  - by djhworld

  Hi there, I'm trying to dive into the quite frankly terrible world of unit testing using Xcode (such a convoluted process it seems.) Basically I have this test class, attempting to test my Show.h class #import <GHUnit/GHUnit.h> #import "Show.h" @interface ShowTest : GHTestCase { } @end @implementation ShowTest - (void)testShowCreate { Show *s = [[Show alloc] init]; GHAssertNotNil(s,@"Was nil."); } @end However when I try to build and run my tests it moans with this error: - Undefined symbols: "_OBJC_CLASS_$_Show", referenced from: __objc_classrefs__DATA@0 in ShowTest.o ld: symbol(s) not found collect2: ld returned 1 exit status Now I'm presuming this is a linking error. I tried following every step in the instructions located here: - http://github.com/gabriel/gh-unit/blob/master/README.md And step 2 of these instructions confused me: - In the Target 'Tests' Info window, General tab: Add a linked library, under Mac OS X 10.5 SDK section, select GHUnit.framework Add a linked library, select your project. Add a direct dependency, and select your project. (This will cause your application or framework to build before the test target.) How am I supposed to add my project to the linked library list when all it accepts it .dylib, .framework and .o files. I'm confused! Thanks for any help that is received.

• Call private methods and private properties from outside a class in PHP

  - by Pablo López Torres

  I want to access private methods and variables from outside the classes in very rare specific cases. I've seen that this is not be possible although introspection is used. The specific case is the next one: I would like to have something like this: class Console { final public static function run() { while (TRUE != FALSE) { echo "\n> "; $command = trim(fgets(STDIN)); switch ($command) { case 'exit': case 'q': case 'quit': echo "OK+\n"; return; default: ob_start(); eval($command); $out = ob_get_contents(); ob_end_clean(); print("Command: $command"); print("Output:\n$out"); break; } } } } This method should be able to be injected in the code like this: Class Demo { private $a; final public function myMethod() { // some code Console::run(); // some other code } final public function myPublicMethod() { return "I can run through eval()"; } private function myPrivateMethod() { return "I cannot run through eval()"; } } (this is just one simplification. the real one goes through a socket, and implement a bunch of more things...) So... If you instantiate the class Demo and you call $demo-myMethod(), you'll get a console: that console can access the first method writing a command like: > $this->myPublicMethod(); But you cannot run successfully the second one: > $this->myPrivateMethod(); Do any of you have any idea, or if there is any library for PHP that allows you to do this? Thanks a lot!

• GHC 6.12 and MacPorts

  - by absz

  I recently installed GHC 6.12 and the Haskell Platform 2010.1.0.1 on my Intel MacBook running OS X 10.5.8, and initially, everything worked fine. However, I discovered that if I use cabal install to install a package which depends on a MacPorts library (e.g., cabal install --extra-lib-dirs=/opt/local/lib --extra-include-dirs=/opt/local/include gd), things work fine in GHCi, but if I try to compile, I get the error Linking test ... Undefined symbols: "_iconv_close", referenced from: _hs_iconv_close in libHSbase-4.2.0.0.a(iconv.o) "_iconv", referenced from: _hs_iconv in libHSbase-4.2.0.0.a(iconv.o) "_iconv_open", referenced from: _hs_iconv_open in libHSbase-4.2.0.0.a(iconv.o) ld: symbol(s) not found collect2: ld returned 1 exit status After some Googling, I found a long Haskell-cafe thread discussing this problem. The upshot seems to be that MacPorts installs an updated version of libiconv, and the binary interface is slightly different from the version included with the system. Consequently, if you try to link with any MacPorts library, the MacPorts libiconv gets linked in too; and since the base library was built to link against a different version of libiconv, things break. I've tried setting LD_LIBRARY_PATH and DYLD_LIBRARY_PATH and adding more flags to try to get it to look at /usr/lib again (e.g. cabal install --extra-lib-dirs=/opt/local/lib --extra-include-dirs=/opt/local/include --extra-lib-dirs=/usr/lib --extra-include-dirs=/usr/include gd), but neither worked. Uninstalling the MacPorts libiconv isn't really an option, since I have a bunch of ports installed which depend on it---including some ports I want Haskell to link to, like gd2. From what I've seen online, the upshot really seems to be "you're boned": you cannot link against any MacPorts library while compiling with GHC, and there doesn't seem to be a solution. However, that thread was from the end of 2009, so I figure there's a chance that someone has a solution, workaround, ridiculous hack… anything, really. So: does anybody know how to get GHC 6.12 to link against the system libiconv at the same time as it links to libraries from MacPorts? Or, failing that, a way to make linking not break in some other clever way?

• Problem with non blocking fifo in bash

  - by timdel

  Hi! I'm running a few Team Fortress 2 servers and I want to write a little management script. Basically the TF2 servers are a fg process which provides a server console, so I can start the server, type status and get an answer from it: ***@purple:~/tf2$ ./start_server_testing Auto detecting CPU Using AMD Optimised binary. Server will auto-restart if there is a crash. Console initialized. [bla bla bla] Connection to Steam servers successful. VAC secure mode is activated. status hostname: Team Fortress version : 1.0.6.1/15 3883 secure udp/ip : ***.***.133.31:27600 map : ctf_2fort at: 0 x, 0 y, 0 z players : 0 (2 max) # userid name uniqueid connected ping loss state adr Great, now I want to create a script which sends the command sm_reloadadmins to all my servers. The best way I found to do this is using a fifo named pipe. Now what I want to do is having this pipe readonly and non blocking to the server process, so I can write into the pipe and the server executes it, but still I want to write via console one the server, so if I switch back to the fg process of the server and I type status I want an answer printed. I tried this (assuming serverfifo is mkfifo serverfifo): ./start_server_testing < serverfifo Not working, the server won't start until something is written to the pipe. ./start_server_testing <> serverfifo Thats actually working pretty good, I can see the console output of the server and I can write to the fifo and the server executes the commands, but I can't write via console to the server anymore. Also, if I write 'exit' to the pipe (which should end the server) and I'm running it in a screen the screen window is getting killed for some reason (wtf why?). I only need the server to read the fifo without blocking AND all my keyboard input on the server itself should be send to the server AND all server ouput should be written to the console. Is that possible? If yes, how?

• What is the right way to scale a Flex application up to fullscreen?

  - by Impirator

  Fullscreen mode and I have been battling for a while in this Flex application, and I'm coming up short on Google results to end my woes. I have no problem going into fullscreen mode by doing a Application.application.stage.displayState = StageDisplayState.FULL_SCREEN;, but the rest of the content just sits there in the top, left corner at it's original size. All right, says I, I'll just do a stage.scaleMode = StageScaleMode.SHOW_ALL and make it figure out how to pull this off. And it looks like it does. Except that when you mouse over the individual checkboxes and buttons and various components, they all fidget slightly. Just a slight jump up or down as they resize...on mouse over. Well, this is frustrating, but bearable. I can always just invoke invalidateSize() explicitly for all of them. But for the comboboxes. The ones at the bottom have their menus go off the bottom of the screen, and when I pop out of fullscreen mode, their drop downs cut off half way. I have no idea how to fix that. Can someone step in here, and put me out of my misery? What is the right way to scale a Flex application up to fullscreen? var button:Button = button_fullscreen; try { if(stage.displayState == StageDisplayState.FULL_SCREEN) { Application.application.stage.displayState = StageDisplayState.NORMAL; button.label = "View Fullscreen Mode"; stage.scaleMode = StageScaleMode.NO_SCALE; } else { Application.application.stage.displayState = StageDisplayState.FULL_SCREEN; button.label = "Exit Fullscreen Mode"; stage.scaleMode = StageScaleMode.SHOW_ALL; } invalidateSizes(); // Calls invalidateSize() explicitly on several components. } catch(error:SecurityError) { Alert.show("The security settings of your computer prevent this from being displayed in fullscreen.","Error: "+error.name+" #"+error.errorID); } catch(error:Error) { Alert.show(error.message,error.name+" #"+error.errorID); }

• Simple way to decrease values without making a new attribute?

  - by Jam

  I'm making a program where you're firing a 'blaster', and I have 5 ammo. I'm blasting an alien who has 5 health. At the end I instantiate the player and make him blast 6 times to check that the program works correctly. But the way I've done it makes it so that the amount won't decrease. Is there an easy fix to this, or do I just have to make a new attribute for ammo and health? Here's what I have: class Player(object): """ A player in a shooter game. """ def blast(self, enemy, ammo=5): if ammo>=1: ammo-=1 print "You have blasted the alien." print "You have", ammo, "ammunition left." enemy.die(5) else: print "You are out of ammunition!" class Alien(object): """ An alien in a shooter game.

• Java: does the EDT restart or not when an exception is thrown?

  - by NoozNooz42

  (the example code below is self-contained and runnable, you can try it, it won't crash your system :) Tom Hawtin commented on the question here: http://stackoverflow.com/questions/3018165 that: It's unlikely that the EDT would crash. Unchecked exceptions thrown in EDT dispatch are caught, dumped and the thread goes on. Can someone explain me what is going on here (every time you click on the "throw an unchecked exception" button, a divide by zero is performed, on purpose): import javax.swing.*; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.WindowAdapter; import java.awt.event.WindowEvent; public class CrashEDT extends JFrame { public static void main(String[] args) { final CrashEDT frame = new CrashEDT(); frame.addWindowListener(new WindowAdapter() { public void windowClosing( WindowEvent e) { System.exit(0); } }); final JButton jb = new JButton( "throw an unchecked exception" ); jb.addActionListener( new ActionListener() { public void actionPerformed( ActionEvent e ) { System.out.println( "Thread ID:" + Thread.currentThread().getId() ); System.out.println( 0 / Math.abs(0) ); } } ); frame.add( jb ); frame.setSize(300, 150); frame.setVisible(true); } } I get the following message (which is what I'd expect): Exception in thread "AWT-EventQueue-0" java.lang.ArithmeticException: / by zero and to me this is an unchecked exception right? You can see that the thread ID is getting incremented every time you trigger the crash. So is the EDT automatically restarted every time an unchecked exception is thrown or are unchecked exceptions "caught, dumped and the thread goes on" like Tom Hawtin commented? What is going on here?

• accelerating Wheel - psychtoolbox in matlab

  - by ariel

  Hi I am trying to write a code that will show an acceleration wheel. as long as the user press 'a' the wheel should accelerate counterclock wize. the thing is that it turn in the right direction but it doesn't accelerate. This is the code I am using . PTB-3 windows XP. img=imread('c:\images.jpg'); [yimg,ximg,z]=size(img); rot_spd = 1; larrow = KbName('a'); % modify this for Windows rarrow = KbName('b'); [w,rect]=Screen('OpenWindow',0,[0 0 0]); sx = 400; % desired x-size of image (pixels) sy = yimg*sx/ximg; % desired y-size--keep proportional t = Screen('MakeTexture',w,img); bdown=0; th = 0; % initial rotation angle (degrees) HideCursor while(~any(bdown)) % exit loop if mouse button is pressed [x,y,bdown]=GetMouse; [keyisdown,secs,keycode] = KbCheck; if(keycode(larrow)) th = th - rot_spd-1; % accelerate counterclockwise th end if(keycode(rarrow)) th = th + rot_spd+1; % accelerate clockwise th end destrect=[x-sx/2,y-sy/2,x+sx/2,y+sy/2]; Screen('DrawTexture',w,t,[],destrect,th); Screen('Flip',w); end Screen('Close',w) ShowCursor If anyone has an odea why it doesn't accelerate I'd appriciate it very much.

• Blackberry how to display message in app if device got no internet connection?

  - by Johannes

  Hello I've just started with programming for the Blackberry device. I'm using version 5 of the API. I'm building a very simple application which is just a browserfield. So far it's all working great. I can display my browserfield with the content I need. The problem I'm having now is if the device doesn't have an active internet connection I get the ugly "Error requesting content for" message. I would need to someone display my own message if the device doesn't have an active connection. Something like "You need to have an active internet connection to use this application" with an Exit button which closes the app. I've tried to find this for hours but no luck. Hopefully it's something relatively easy so I can get help here. Here's my code so far: package com.mycompany.webview; import net.rim.device.api.browser.field2.*; import net.rim.device.api.ui.*; import net.rim.device.api.ui.container.*; public class webview extends UiApplication { public static void main(String[] args) { webview app = new webview(); app.enterEventDispatcher(); } public webview() { pushScreen(new webviewScreen()); } } class webviewScreen extends MainScreen { public webviewScreen() { BrowserField myBrowserField = new BrowserField(); add(myBrowserField); myBrowserField.requestContent("http://www.google.com"); } } Would really appreciate some help please. Thanks

• Parsing some particular statements with antlr3 in C target

  - by JCD

  Hello all! I have some questions about antlr3 with tree grammar in C target. I have almost done my interpretor (functions, variables, boolean and math expressions ok) and i have kept the most difficult statements for the end (like if, switch, etc.) 1) I would like interpreting a simple loop statement: repeat: ^(REPEAT DIGIT stmt); I've seen many examples but nothing about the tree walker (only a topic here with the macros MARK() / REWIND(m) + @init / @after but not working (i've antlr errors: "unexpected node at offset 0")). How can i interpret this statement in C? 2) Same question with a simple if statement: if: ^(IF condition stmt elseifstmt* elsestmt?); The problem is to skip the statement if the condition is false and test the other elseif/else statements. 3) I have some statements which can stop the script (like "break" or "exit"). How can i interrupt the tree walker and skip the following tokens? 4) When a lexer or parser error is detected, antlr returns an error. But i would like to make my homemade error messages. How can i have the line number where parser crashed? Ask me if you want more details. Thanks you very much (and i apologize for my poor english)

• How to eliminate Unhandled Exception dialog produced by 3rd party application

  - by Tappen

  I'm working with a 3rd party executable that I can't recompile (vendor is no longer available). It was originally written under .Net 1.1 but seems to work fine under later versions as well. I launch it using Process.Start from my own application (I've tried p/invoke CreateProcess as well with the same results so that's not relevant) Unfortunately this 3rd party app now throws an unhandled exception as it exits. The Microsoft dialog box has a title like "Exception thrown from v2.0 ... Broadcast Window" with the version number relating to the version of .Net it's running under (I can use a .exe.config file to target different .Net versions, doesn't help). The unhandled exception dialog box on exit doesn't cause any real problems, but is troubling to my users who have to click OK to dismiss it every time. Is there any way (a config file option perhaps) to disable this dialog from showing for an app I don't have the source code to? I've considered loading it in a new AppDomain which would give me access to the UnhandledException event but there's no indication I could change the appearence of the dialog. Maybe someone knows what causes the exception and I can fix this some other way?

• Newtonsoft JSON Interface Serialization error

  - by Ben

  I am using C# .NET 4.0, Newtonsoft JSON 4.5.0. public class Recipe { [JsonProperty(TypeNameHandling = TypeNameHandling.All)] public List<IFood> Foods{ get; set; } ... } I want to serialize and deserialize this Recipe object. If I serialize and deserialize the object during application lifetime this succeeds, but if I serialize the object, exit application and then deserialize it then it throws an exception, that it cannot instantiate IFood (since it is an interface). The problem is that it does not serialize the implementation of interface. "$type": "System.Collections.Generic.List`1[[NSM.Shared.Models.IFood, NSMShared]], mscorlib" I tried using TypeNameHandling.Object and Array and Auto, but it didn't help. Is there any way to serialize it properly? Or at least to define the class mapping before deserializing? EDIT: I am using JSON coupled with Hammock ( http://code.google.com/p/relax-net/ ), C# driver for CouchDB, which internally serializes and deserializes objects. As mentioned the problem is that it does not serialize the interface implementation.

• configure.in: AM_DISABLE_SHARED doesn't change my Makefile

  - by t2k32316

  I'm extremely new to using Makefiles and autoconf. I'm using the Camellia image library and trying to statically link my code against their libraries. When I run "make" on the Camellia image library, I get libCamellia.a, .so, .la, and .so.0.0.0 files inside my /usr/local/lib directory. This is the command I use to compile my code with their libraries: gcc -L/usr/local/lib -lCamellia -o myprogram myprogram.c This works fine, but when I try to statically link, this is what I get: gcc -static -L/usr/local/lib -lCamellia -o myprogram myprogram.c /tmp/cck0pw70.o: In function `main': myprogram.c:(.text+0x23): undefined reference to `camLoadPGM' myprogram.c:(.text+0x55): undefined reference to `camAllocateImage' myprogram.c:(.text+0x97): undefined reference to `camZoom2x' myprogram.c:(.text+0x104): undefined reference to `camSavePGM' collect2: ld returned 1 exit status I want to statically link because I'm trying to modify the Camellia source code and I want to compare my version against theirs. So after some googling, I tried adding AM_DISABLE_SHARED into the configure.in file. But after running ./configure, I still get the exact same Makefile. After I "make install", I still get the same results above. What is an easy way to get two versions of my code, one with the original Camellia source code compiled and one with my modified version? I think static libraries should work. There is an easy way to get static libraries working or are there other simple solutions to my problem? I just don't want to re-"make" and re-"make install" everytime I want to compare my version against the original.
