• Tomcat startup fails with not a valid identifier

  - by Nigel

  I have tomcat 6.0.18 running on one server without a problem. With the exact same settings it fails to launch on my colleague's machine. He's even running from the same folder as me (I've stopped my copy while he tries to make it work) All we get when we fire off tomcat using bin/startup.sh is this: CATALINA_OPTS=-server -Xms768m -XX:+UseParallelGC -Xmx768m -XX:MaxPermSize=256m -XX:PermSize=128m -Djava.awt.headless=true: is not an identifier I had that definition in setenv.sh and moved it into startup.sh - same problem. Any suggestions? My brief look on google seem to indicate multiple IP address issues, but my server has two ethernet cards, and two IP addresses. Thanks.

• How to print lines from a file that have repeated more than six times

  - by Mike

  I have a file containing the data shown below. The first comma-delimited field may be repeated any number of times, and I want to print only the lines after the sixth repetition of any value of this field For example, there are eight fields with 1111111 as the first field, and I want to print only the seventh and eighth of these records Input file: 1111111,aaaaaaaa,14 1111111,bbbbbbbb,14 1111111,cccccccc,14 1111111,dddddddd,14 1111111,eeeeeeee,14 1111111,ffffffff,14 1111111,gggggggg,14 1111111,hhhhhhhh,14 2222222,aaaaaaaa,14 2222222,bbbbbbbb,14 2222222,cccccccc,14 2222222,dddddddd,14 2222222,eeeeeeee,14 2222222,ffffffff,14 2222222,gggggggg,14 3333333,aaaaaaaa,14 3333333,bbbbbbbb,14 3333333,cccccccc,14 3333333,dddddddd,14 3333333,eeeeeeee,14 3333333,ffffffff,14 3333333,gggggggg,14 3333333,hhhhhhhh,14 Output: 1111111,gggggggg,14 1111111,hhhhhhhh,14 2222222,gggggggg,14 3333333,gggggggg,14 3333333,hhhhhhhh,14 What I have tried is to transponse the 2nd and 3rd fields with respect to 1st, so that I can use nawk on the field of $7 or $8 #!/usr/bin/ksh awk -F"," '{ a[$1]; b[$1]=b[$1]","$2 c[$1]=c[$1]","$3} END{ for(i in a){ print i","b[i]","c[i]} } ' file > output.txt

• Integrating Hudson with MS Test?

  - by hangy

  Is it possible to integrate Hudson with MS Test? I am setting up a smaller CI server on my development machine with Hudson right now, just so that I can have some statistics (ie. FxCop and compiler warnings). Of course, it would also be nice if it could just run my unit tests and present their output. Up to now, I have added the following batch task to Hudson, which makes it run the tests properly. "%PROGRAMFILES%\Microsoft Visual Studio 9.0\Common7\IDE\MSTest.exe" /runconfig:LocalTestRun.testrunconfig /testcontainer:Tests\bin\Debug\Tests.dll However, as far as I know, Hudson does not support analysis of MS Test results, yet. Does anyone know whether the TRX files generated by MSTest.exe can be transformed to the JUnit or NUnit result format (because those are supported by Hudson), or whether there is any other way to integrate MS Test unit tests with Hudson?

• how do I filter RoutingErrors and their long stack trace out of my log? rails

  - by codeman73

  I am seeing several strange requests like this, with urls like /sitemap/, /google_sitemap.xml.gz, /sitemap.xml.gz, /google_sitemap.xml, /cgi-bin/awstat/awstats.pl, etc. The default rails behavior dumps these long stack traces into my log, like the following: ActionController::RoutingError (No route matches "/rails/info/properties" with {:method=>:get}): /dh/passenger/lib/phusion_passenger/rack/request_handler.rb:92:in `process_request' /dh/passenger/lib/phusion_passenger/abstract_request_handler.rb:207:in `main_loop' /dh/passenger/lib/phusion_passenger/railz/application_spawner.rb:400:in `start_request_handler' /dh/passenger/lib/phusion_passenger/railz/application_spawner.rb:351:in `handle_spawn_application' /dh/passenger/lib/phusion_passenger/utils.rb:184:in `safe_fork' etc. Is there any way to stop these long stack traces? I wouldn't mind the first line, the ActionController::RoutingError with the message and the url, but I'd like to get rid of the long stack of passenger stuff.

• very weird problem concerning date and time in silverlight + ria services

  - by Patrick LHM

  Hello Friends i'm facing a very weird problem in sliverlight 4 + RIA Services, or maybe it's not weird and i'm just a newbie anyway i hope someone here can help, the problem is the following i've created a function on the server side inside the domain service this function is very simple and has a line in it that adds the server current date and time to the database (it's an HR application and employees should sign in and out thrue it each from it's own pc ) Emp.TimeOut = system.DateTime.now (C# syntax) the weird part is that for some users it always adds 3 hours to the current time(exp if he signes out at 5 it shows 8) and for others it works perfectly. the server and all the stations in the company have exactly the same time settings and the same time zone, and anyway my fucntion is on the server side so it should no be realted to the users time. any ideas why this is happening ? i've bin trying to find out why for days now but with no luck

• Using memory mapping in C for reading binary

  - by user1320912

  I am trying to read data from a binary file and process it.It is a very large file so I thought I would use memory mapping. I am trying to use memory mapping so I can read the file byte by byte. I am getting a few compiler errors while doing this. I am doing this on a linux platform #include <unistd.h> #include <sys/types.h> #include <sys/mman.h> int fd; char *data; fd = open("data.bin", O_RDONLY); pagesize = 4000; data = mmap((caddr_t)0, pagesize, PROT_READ, MAP_SHARED, fd, pagesize); The errors i get are : caddr not initialized, R_RDONLY not initialized, mmap has too few arguments. Could someone help me out ?

• How do I change the JAVA_HOME for ant?

  - by Eugene M

  I'm doing java work on a class server where I don't have root. Whenever I try to compile using ant, it points to the wrong directory (/usr/tomcat instead of /usr/tomcat/jre ). One of the things we were told to do when setting up our user accounts was to add export JAVA_HOME=/usr/tomcat/jre to the .bashrc file. I don't know if that was supposed to take care of the problem but it doesn't seem to. So, how can I change the JAVA_HOME property for ant but only for when I run ant? EDIT: echo $JAVA_HOME points to /usr/tomcat/jre echo $JAVA_HOME\bin points to /usr/tomcat/jrebin The problem is when I normally run ant I get this error: Unable to locate tools.jar. Expected to find it in /usr/tomcat/lib/tools.jar Buildfile: build.xml compile: [javac] Compiling 1 source file to /home/ejm244/build/classes BUILD FAILED /home/ejm244/build.xml:9: Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath. Perhaps JAVA_HOME does not point to the JDK Total time: 0 seconds

• Qt on Mac: where to find "configure"

  - by Gil

  hi, I am very new to Mac. I downloaded QT SDK Mac Open source (http://get.qt.nokia.com/qtsdk/qt-sdk-mac-opensource-2010.02.dmg) and installed the Package. I can run qmake, build samples and run demos, but I cannot run configure (in order to build the Qt libraries statically). It says: -bash: No such file or directory. Documentation says I should run this in the "Qt root folder", but what is this folder in Mac? I looked for it in /usr/bin, /usr/local/Qt4.6, /Developer/Tools/Qt. Anyway, what is "configure" on Mac. is it an executable or a script? Thanks a lot

• PHP exec not working with gcc

  - by teehoo

  I just spent a few hours pulling my hair out over this. I'm trying to get gcc to compile a file from within PHP. $command = "/usr/bin/gcc /var/www/progpad/temp/tNu7rq.c -o /var/www/progpad/temp/tNu7rq.out"; exec($command, $output, $returnVal); echo $returnVal."<br />"; //returns 1 echo json_encode($output); //returns [] I'm running this on my own ubuntu server and both /var/www/progpad/ /var/www/progpad/temp/ have chmod 777 set. If I copy and paste the command string, and paste it into the terminal it works perfectly. Also if I replace the command string with something like $command = "echo test > test.txt"; Then this has no problem creating the text file. What could I possibly be doing wrong here???

• How to install the program depending on libstdc++ library

  - by Alex Farber

  My program is written in C++, using GCC on Ubuntu 9.10 64 bit. If depends on /usr/lib64/libstdc++.so.6 which actually points to /usr/lib64/libstdc++.so.6.0.13. Now I copy this program to virgin Ubuntu 7.04 system and try to run it. It doesn't run, as expected. Then I add to the program directory the following files: libstdc++.so.6.0.13 libstdc++.so.6 (links to libstdc++.so.6.0.13) and execute command: LD_LIBRARY_PATH=. ./myprogram Now everything is OK. The question: how can I write installation script for such program? myprogram file itself should be placed to /usr/local/bin. What can I do with dependencies? For example, on destination computer, /usr/lib64/libstdc++.so.6 link points to /usr/lib64/libstdc++.so.6.0.8. What can I do with this? Note: the program is closed-source, I cannot provide source code and makefile.

• Python subprocess.Popen hangs in 'for l in p.stdout' until p terminates, why?

  - by Albert

  I have that code: #!/usr/bin/python -u localport = 9876 import sys, re, os from subprocess import * tun = Popen(["./newtunnel", "22", str(localport)], stdout=PIPE, stderr=STDOUT) print "** Started tunnel, waiting to be ready ..." for l in tun.stdout: sys.stdout.write(l) if re.search("Waiting for connection", l): print "** Ready for SSH !" break The "./newtunnel" will not exit, it will constantly output more and more data to stdout. However, that code will not give any output and just keeps waiting in the tun.stdout. When I kill the newtunnel process externally, it flushes all the data to tun.stdout. So it seems that I can't get any data from the tun.stdout while it is still running. Why is that? How can I get the information? Note that the default bufsize for Popen is 0 (unbuffered). I can also specify bufsize=0 but that doesn't change anything.

• Best Tools for Software Maintenance Engineering

  - by Pev

  Yes, the dreaded 'M' word. You've got a workstation, source control and half a million lines of source code that you didn't write. The documentation was out of date the moment that it was approved and published. The original developers are LTAO, at the next project/startup/loony bin and not answering email. What are you going to do? {favourite editor} and Grep will get you started on your spelunking through the gnarling guts of the code base but what other tools should be in the maintenance engineers toolbox? To start the ball-rolling; I don't think I could live without source-insight for C/C++ spelunking. (DISCLAIMER: I don't work for 'em).

• PHP imap_search not detecting all messages in gmail inbox

  - by Steve

  When I run a very simple imap_search on my GMail inbox, the search returns less messages than it should. Here is the script that anyone with a GMail account can run. $host = '{imap.gmail.com:993/imap/ssl}'; $user = 'foo'; $pass = 'bar'; $imapStream = imap_open($host,$user,$pass) or die(imap_last_error()); $messages = imap_search($imapStream,"ALL"); echo count($messages); imap_close($imapStream); This returns 39 messages. But, I've got 100 messages in my inbox, some in conversations, some forwarded from another account (SquirrelMail, FWIW). Can anyone duplicate these results, and/or tell me what's going on? Other server strings I've tried, all returning the same results: {imap.gmail.com:993/imap/ssl/novalidate-cert} {imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX {imap.gmail.com:993/imap/ssl}INBOX GMail's IMAP feature support: http://mail.google.com/support/bin/answer.py?hl=en&answer=78761

I have been working through copying required dlls from C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5 into my app bin directory. This succesfully got me past the "assembly not found" errors. However, I am now getting the error: "Compiler executable file csc.exe cannot be found". Does anyone know how I can fix this? It is primarily LINQ functionality I am looking to utilise. Many thanks!!

• How can I create a custom cleanup mode for git?

  - by Danny

  Git's default cleanup of strip removes all lines starting with a # character. Unfortunately, the Trac engine's wiki formatter uses hashes in the beginning of a code block to denote the syntax type. Additionally any code added verbatim might include hashes as they are a common comment prefix; Perl comes to mind. In the following example the comments all get destroyed by git's cleanup mode. Example: {{{ #!/usr/bin/perl use strict; # say hi to the user. print "hello world\n"; }}} I'd like to use a custom filter that removes all lines beginning with a hash from the bottom of the file upwards. Leaving those lines that being with a hash that are embedded in the commit message I wrote alone. Where or how can I specify this in git? Note, creating a sed or perl script to perform the operation is not a problem, just knowing where to hook it into git is the question.

• Removing final bash script argument

  - by ctuffli

  I'm trying to write a script that searches a directory for files and greps for a pattern. Something similar to the below except the find expression is much more complicated (excludes particular directories and files). #!/bin/bash if [ -d "${!#}" ] then path=${!#} else path="." fi find $path -print0 | xargs -0 grep "$@" Obviously, the above doesn't work because "$@" still contains the path. I've tried variants of building up an argument list by iterating over all the arguments to exclude path such as args=${@%$path} find $path -print0 | xargs -0 grep "$path" or whitespace="[[:space:]]" args="" for i in "${@%$path}" do # handle the NULL case if [ ! "$i" ] then continue # quote any arguments containing white-space elif [[ $i =~ $whitespace ]] then args="$args \"$i\"" else args="$args $i" fi done find $path -print0 | xargs -0 grep --color "$args" but these fail with quoted input. For example, # ./find.sh -i "some quoted string" grep: quoted: No such file or directory grep: string: No such file or directory Note that if $@ doesn't contain the path, the first script does do what I want.

• Making Swedish characters show properly in Windows Command Prompt using Python in Notepad++

  - by Alex

  The title explains it well. I have set up Notepad++ to open the Python script in the command prompt when I press F8 but all Swedish characters looks messed up when opening in CMD but perfectly fine in e.g IDLE. This simple example code: #!/usr/bin/env python #-*- coding: UTF-8 -*- print "åäö" Looks like this. As you can see the output of the batch file I use to open Python in cmd below shows the characters correctly but not the Python script above it. How do I fix this? I open the file in cmd using this method
