Ubuntu :: Eclipse Deadlock Ubuntu 10.04 While Debuging
May 28, 2010
I am using Ubuntu 10.04 64 bit on my vaio VGN-NS325j. Using Eclipse as my IDE. But i have a big problem ; while i am debugging my app. It is locking my interface. No more responses for my mouse clicks or keyboard.. Machine is still working.. If there is an application running on background it is continuing what it is job is.But i could interact with anything. It is just happening during debugging.. Otherwise it is fine.In addition my app is running on Jboss 4.2.2 if it helps.

I have been using Eclipse to program in Java for a long time, and have been using Jigloo for most of my GUI design. Recently I decided to try out the C/C++ plugin. I tried installing it, but it did not work. After many attempts, I finally gave up. However, after uninstalling it I found that Jigloo had stopped working. Any other plugins I try to install now also don't work. I have tried uninstalling and reinstalling plugins, and reinstalling eclipse, but nothing I have done fixes it. Although eclipse says that the software has been installed, nothing shows up in the features list or the plugins list.
Another problem: When I install eclipse from the repositories, it doesn't install a bunch of libraries and eclipse cannot recognize standard java files.

The following two pieces of codes share printing to stdout with a POSIX semaphore /dev/shm/sem.abcd
sema1.c:
Code:
int j;
sem_t *sem = sem_open( "/abcd", O_CREAT, S_IRUSR|S_IWUSR, 1 );
j = 0;
while (j < 100) {
[Code].....
If started at the same time, the first will finish in about 10 seconds; the second 20 secs.
What I want to ask is, if the first program crashes at Checkpoint A, then B will never gets to continue, then normally how do programmers avoid this kind of deadlock due to crashes inside the critical section?

Thanks to a recommendation and extensive help at phpbuilder.com, I have a multithreaded PHP script running in the cloud which fetches images and stores them the cloud. It's fast and seems quite stable.However, I believe I'm faced with a situation where I need to introduce an additional lock to my code so I'm faced with the task of managing multiple locks while avoiding deadlock.I was wondering if anyone had experience managing multiple locks in a MT environment and could recommend specific functions and data structures. I've been reading up on resource management in MT code and understand a few things:
1) Any shared resource (global and static vars, memory, file descriptors, etc.) generally needs to be protected by some kind of mutex, lock, or other sync var.
2) There are certain necessary conditions for deadlock to occur.
3) You generally need a sequence or hierarchy of your resources so that all threads request them in the same order. This sequence must be the same and immutable for all participating threads, whether local or remote.
4) Recursion is a very common cause of deadlock, so a process should know what locks it has acquired previously in order to avoid blocking in the attempt to re-acquire those same locks again.
5) There are a variety of algorithms described such as the Banker's Algorithm, the Chandy/Misra solution, etc. to help avoid deadlock.
I'm hoping to come up with a technique for properly handling multiple locks/mutexes/sync vars that I can re-use in the future, but I'm still coming to grips with the algorithm descriptions and am unsure precisely what sorts of data structures or functions I'll need.

I know Zend stands behind PHP and that Eclipse is a popular open source IDE. What is the difference tho?Is the PDT Project only a functionality that could be added to Eclipse IDE? Is Zend for Eclipse a stand alone IDE for PHP? if so, Why the Eclipse in the name? I have downloaded Zend Studio for Eclipse, so far it seems very complete (no that have learned how to use all its features).

I would like to know if it supports Eclipse CDT, so I can use it with my C++ project. Any thought? If it doesn't support CDT, is there any good static code analysis tools available for Eclipse CDT?

I am new to Fedora (I have always used ubuntu in the past), and I am trying to download eclipse. Unfortunately, "sudo yum install eclipse" is returning "no package eclipse available". I think this means that I am missing the correct repo, but I'm not sure which is the right one and don't know how to add it to my repo list for this version. My version of fedora is centos5 based, and my current repo list is the following:

I am connecting servers using NFS4 the shared directories are on servers running Debian 4 while the one who read from them is Debian 5.0.3. The problem is one of these shared servers suddenly stop responding and you cannot list it from Debian 5 server, also df hang, and the web application that is using it does not respond to requests that use this shared directory since it is blocked. Then the load on the server start to increase until the server cannot respond (over 90). I have found many entries in the syslog that refer to this like:
ma25555 kernel: [1200285.732919] nfs: server 10.xxx.xxx.xxx not responding, still trying
Dec 31 08:16:33 ma25555 kernel: [1200289.815378] INFO: task java:9702 blocked for more than 120 seconds.
Dec 31 08:16:33 ma25555 kernel: [1200289.835249] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
code....
I have tried the connection between the 2 servers using ping for one day and all are OK (zero lost)
There are 3 other servers that are running Debian 4 and are working fine.

I have my desktop with following hardware:
1. MB: ASUS P5QL SE/EPU
2. RAM: 2 x 2GB Corsair PC2-8500 (1066 MGhz)
3. CPU: Intel Dual-Core E6500
4. GPU: nVidia GeForce 9400 GT with binary driver
5. Net: D-Link DWA-520 with madwifi driver
This machine is running for more than two years without any problem, but during the last 2 or 3 months I get deadlock hangs once or twice a week. This machine runs Slackware-current 32 bit with custom compiled vanilla kernel with two additional patches - BFS and TuxOnIce. Deadlocks usually occur when there is no user activity - only rtorrent is running and two KDE4 sessions is open (with firefox, okular, claws-mail, goldendict, virtualbox and other memory consuming apps).
Here is an excerpt from my syslog:
Quote:
I just would like to get a clue - what should I replace first - a memory or a CPU? The price is almost the same - around hundred of bucks. I tried to run memtest86 3.5a and got 1983 memory errors, but I had several problems with false positive errors with earlier versions of memtest86 and I don't trust it on 100%. My idea is to update BIOS firmware, update to the new kernel (I'm waiting for 2.6.37) and only then replace a RAM.

I install eclipse via the synaptic package manager and it did work before but I was messing around with some svn packages and corrupted it. So naturally I did a complete removal of anything related to eclipse and reinstalled all the packages after, but to no avail problem still persists. here is the log file it tells me to look at, can really make head or tales of this stack error info, not really a big Java man.I have a 64bit install of ubuntu 9.10Quote:

I use eclipse 3.5.2 for developing web applications (servlets,JSP) and Java programs. The problem is that I don't know how to update it, I mean it's not updated automatically through the update manager, so I guess I need to add something in the repositories. Anyway inside eclipse, in the help menu, there's the button "check for updates", but after it searches for new versions, it says "there's nothing to update". Is there a way to update it through the update manager? And how can I do it?

Today, eclipse will not start for me. The initial splash screen comes up, then the attached window pops-up with not text in it...the only way to get rid of the window is to kill the eclipse process from the terminal/command-line.
I have completely purged and reinstalled java and eclipse, but am still having the same issue. Starting from the terminal also does not give any message besides the "(eclipse:15273): GLib-WARNING **: g_set_prgname() called multiple times" warning. Any ideas or suggestions?
Btw, running Ubuntu 9.10 x86 and the most up-to-date eclipse that is in the repos.

My Eclipse just stopped working all of sudden. This happened after I deleted some directories in my workspace, but I doubt that had anything to do with it.
I just get a small empty window when I try to run it. See attached png file.

installing eclipse for Java and C++ IDE. I'm a partial newb coming from Windows and in windows I used JCreator but I now JCreator doesn't have a linux install. So I was going to use Eclipse but I don't know to actually install it. I've already downloaded the tar.bz for the java IDE. I will also need to know the installation for the C++ Ide because I want to start programming with c++.

Eclipse no longer works in 10.10 desktop 64bit, latest update.
The error:
The program 'Eclipse' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.

I wish to use the new Eclipse Galileo, and so far it works fine... out of my home directory.I would like to install this system-wide, so that all my users can use it just the same.I assume the destination would be /usr/local/bin, but when I put the directory there and link the executable as /usr/local/bin/eclipse (linking to /usr/local/bin/eclipse_bin/eclipse), I get shared library errors.This was a failed attempt at a hack, so I would like to know: where can I put the files so as to properly do this installation?
