Programming :: Using Realloc Multiple Times / 4th Iteration In The Loop Realloc Fails In Strarray_add?
Feb 27, 2010
I have a string problem with a function I am writing and I cant figure it out. I am trying to write unit test which will verify it works as expected. As I need to make use of it elsewhere and obviously robust and correct enough that I can rely on it. Okay first of all I define the following structure
I'm trying to write a C program that extends an array to any user inputed size.
Code: if (arraysize == 0) { arraysize = (int) pos + 1; a = (int *) calloc (arraysize,sizeof(int)); for (i = 0 ; i < arraysize ; i++ ) a[i] = -1; code....
The program dumps with that sequence of inputs everytime, but might dump an input before or after if different positions are requested. Interestingly, when I tested pos = 2000..2008, I got no dumps. So is realloc somehow trying to extend the array into bad space?
I wrote a test program for learning usage of realloc() and I thin I did everything right but I get this error exactly with my 4th time that while tries to reallocate memory in MakeDSt function for DSt->SArray:
One of my servers needs to issue an "apt-get update" command on each of the clients in a lab. However, after the first update, it exits. In trying to replicate the problem with a simpler script, I created the following which fetches the listings of multiple directories from a client:
NUM=0 cat paths | while read DIR; do ssh server-name ls $DIR > /tmp/$NUM.txt NUM=`expr $NUM + 1` done
Again, after the first iteration, the script exists. I tried the following line too, but it made no difference:
This is an slice from an other wise successful script. What i need it to do is print one <tr> then print <td>$stat_array</td> fours times, quit print a </tr> then print another <tr> , prints the next four $stat_arrays in @stat_array, and so on and then a </table>.What it does is print all eight $start_arrays then a </tr>
I'm porting C++ application from ARM to MIPS platform. It works now, but I see some strange timing problems. I've seen now that My app process is called multiply time. Here is "top" output:
I used wait4 to time a child process. but the results differ each other dramatically. why?my core source code lists as below.to the point: in linux 2.6 kernel, how to time a process with a high precision. and, only its user-time rather than the elapsed time???
static struct rusage ruse; static pid_t u_pid; int main(int argc, char *argv[]) { int i; code....
I'm programming some skript to get statistical information about some texts. This includes calculating the mean of word lengths.Unfortunately, Umlauts count as two characters. In the example below the output is 9, it should be 6.
sincercly, Max
Code: #!/usr/bin/perl use POSIX; use locale; my $test = length("ABC���"); print $test;
I have tried multiple times to report a bug, but can't. All I can find is this USELESS guide: [URL]Is this seriously the ONLY way to report a bug? I can't just fill out a form somewhere without running software to do it? When I try to do it the way explained in the guide, it tells me that I'm using a stable version of Xubuntu, and that only people running dev versions (like 11.10) can report bugs.Are they saying that all stable releases are perfect in every way? Surely one must be able to report a bug for them...?
I have a strange effect here, where konqueror is started multiple times. It is no problem to start it from the K-Menu. But konqueror seems to be associated with different actions in applications, e.g. many "help" entries; among others e.g. Inkscape: "Hilfe/Inkscape Handbuch" (~ Help/Inkscape handbook") If I'm unfortunate enough to hit such an item, the konqueror items start flooding my task bar, while the mouse cursor - changed to the konqueror icon - is flickering like wild, while konqueror is starting again and again. None of the windows really open and all icons disappear after some time. (due to some resource overflow, but unfortunately I can't find the relevant log entry this time) How can I prevent this ? (Or debug this, if the cause is unclear)
[Staff Note: This thread was spun off from here: HOWTO: Purge and Reinstall Grub 2 from the Live CD This solved the Grub problem but the crashes continue.]
Just as I get up and running again my 10.04 (64 bit) either freezes up totally, closes all windows that are open, fails to restart or shut down forcing a restart.
There's no pattern to it, i might be using the gimp or checking thunderbird emails, possibly just surfing or running bluefish. Nothing major and I'm not one to go delving under the bonnet so to speak and start tweaking things. I have the AWN dock installed and run a dual monitor setup.
Everytime it's crashed, the damn thing doesn't reboot, I get the init =bootarg message I've been reading a lot about and once again I have to run the liveCD and spend several minutes farting about purging and reinstalling grub.
I despise Windows, overall I am enjoying my ubuntu experience but things like this stop me getting any work done.
My PC ran fine for the last 2 days then suddenly it's playing up again. It's not an old machine, quad core processor, plenty of RAM.
I am having to back stuff up as soon as I do it due to so many crashes per day. I have reinstalled the OS and started again from scratch 4 times now in the last month.
The last thing I want to do is go back to Windoze but I am seriously running out of patience with ubuntu.

I have Ubuntu 11.04 on a disk, and installed it on an empty hard drive. When I start my desktop my screen is black with a flashing "_" in the top left corner... Nothing happens. I usually have to restart the computer multiple times before it will actually work. I tried running Ubuntu in recovery mode and fixing any broken packages, but no luck.
how can I rotate logfiles multiple times a day? I notice that the configuration for the logrotate-command is hourly, daily, weekly,.I notice that I can create a cron job where I specify the different times the log rotation need to be done:15 0,8,12,17 * * *But how do I combine these two ?
My 5.5 server has crashed on my multiple times over the past few weeks. I have 2 terabyte drives mirrored.It automatically reboots and seems to run fine after rebooting.I've attached a copy of the /var/log/message to this post.I was unable to paste file.I'm not if a bad disk is causing the problem or not.
I have experienced amarok crash after which i am not able to bring it back to working state. I tried to reinstall it multiple times from standart playground and kde KDE:UpdatedApps repositories. Every time. i start amarok it hangs on splash screen consuming 49% of CPU with no signs to load completely. I guess i need to clean reinstall with deleting all tracing info form previous install?

On Ubuntu 10.04 I would like to setup udev to execute a backup script when a specific USB drive is inserted. Udev detects the USB drive, but my script is executed 7 times instead of just once. Can't figure out what's wrong.
My udev rules file:
Code: /etc/udev/rules.d# cat 20-stick.rules ACTION=="add", ATTRS{vendor}=="Kingston", ATTRS{model}=="DataTraveler G2 ", RUN="/usr/local/bin/sync.sh" Dummy backup script: connecting USB drive results in 7 times date written to /tmp/test code....
I am running 11.04 with the Unity environment from a USB stick. With "Ubuntu Classic", I can open up my Home folder multiple times and thus copy files from one location to another with drag and drop. In Unity, it seems I can only open up one occurrence of the Home folder. Does anyone know if multiple Home folders can be opened up?
I just don't get it? I've attempted multiple times to get the knetworkmanager to connect to an unencrypted network, yet it keeps asking for a wep key. However the networkmanager in the Gnome version connects to unencrypted networks just fine. Why won't knetwork manager do the same?
It's been awhile since I've been on here. I suppose that can be considered a good thing, since I made the completely transfer to Ubuntu three months ago and everything's been running completely smoothly. Anyway, security is a pretty big thing to me. I usually change the root password, take sudo off (and default gksu, not gksudo), encrypt my hard drives, etc... One thing I also do is create a separate password for my login keyring. I don't mind having to enter one extra password at login, but it started prompting two times, and now three. It's the same password every time, so my question is..
When my laptop boots it successfully mounts the NFS NAS and I get an icon "My NAS" on my dekstop that points to the NAS. If I double click on the icon it opens my file browser and I can browse thru my NAS fodlers.
What I see on the left hand side of the file browser is that I have to entries for My NAS. One of it has a button to shows that it is mounted and the other does not.
If I go to Places I also see 2 entries for "My NAS". One of it takes me to browsing the NAS and if I click on the other it says "Unable to mount ... busy or already mounted". Which makes sense.
I am trying to update Flash-player and yast2-core as prompted by today's update icon.
I am now faced with a loop that goes like this: 1) click on icon 2) window pops up, "2 packages selected" 3) click on apply, subwindow pops up 4) click on continue, "waiting for authentication" 5) after minutes of waiting, click on cancel, nothing happens 6) click on icon killing subwindow 7) now back to 2)
Aborting the process, starting at 1) again, same mess
I'm using ubuntu 8.04, and when I load some things, like some games, it tells me I need flash player 10. I have downloaded it multiple times and installed it multiple times but nothing is working as it should. Is it because I'm still on 8.04?
