Re: Server - Linux Compat
When I was young, many many moons ago, and I installed FreeBSD 4.4 for the first time, I enabled linux compatability ... Each build since, I have enabled it ...

All I run is webservers and namesrvers, you know, Bind, Apache, Mysql, vmpop3d, PHP, Exim and shh...not to mention a few utils, ipa, ipfw etc. Does anyone have any compelling reason I should continue to enable linux compatability?

Re: Uplading file via Lighttpd - system hangs
It looks like the freebsd-sendfile is broken. I had the same problems the last days and now I know the source of the problem. Have a look on this PR: http://www.freebsd.org/cgi/query-pr.cgi?pr=125592 Yeah, I looked into this, but I do not see why this has anything to do with sendfile in FreeBSD. When you upload a file, you (the server) don't *send* anything, you *read*, so sendfile(2) shouldn't even come into play. Why this magically starts working when changing the write backend, is a mystery, but most likely the answer lies in PHP. If you can, use a different upload script for testing, one that is not done via PHP, but plain CGI. There should be some available on the net. -- Mel im in a serious doubt that a write() family function could have possibly stop something from responding when login is still accepting read() buffer please dont tell me that a userland process can possibly halt everything unless there is a serious harware malfunction. i think this particular case needs solid debugging and investigation. nash ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: Segmentation fault when free
can someone please explain to me what happens to the
allocated memory
called within a function assigned to its local pointer
after this function
ends
Ok - let's see if I get this right:
- the allocated memory
- called within a function
- assigned to a local pointer
Any malloc'ed memory is application global accessible.
Assigning a pointer to
a variable doesn't allocate memory (the compiler and
runtime libraries
already setup storage for the variable, at declaration
time). So, I have no
idea what you mean with the called within a
function part.
--
Mel
thanks for making it even more clear to me.
actually what i meant was this:
void function(void){
char *p;
p = malloc(1);
}
int main(void){
while (1){
function();
/* in the end of this function function()
* the memory is still allocated
* even when the only pointer who knows its address
* does not longer exist
* which is why we have to free() the memory
* during the application runtime
* to avoid it from growing to ridiculous size
*/
}
}
but even if you kill -SEGV `pgrep this` (Segmentation fault (core dumped) the
memory is getting freed anyway (presumably by the glorious kernel). which you
can see dynamicly by typing top in the console.
in other words segmentation fault when free() is not a scary thing here. it is
a matter of style and the way to find own errors. or maybe reading warnings if
you compile with the flags -ansi -pedantic
oh and by the way:
char *
function(void)
{
char buffer[100];
return buffer;
}
that is an easier approach because you get warned on passing an address to a
local variable

Re: Audio Production
i have experienced a delay when i was recording voice and sort of laying it on a track. but removing a few miliseconds off the beginning didnt make a big trouble for me and thats when i have discovered this phenomenom but thought it was rather because my sound card is old. is this any close to something that you mean? it is related, but what you mentiioned is a slightly different area in computer audio than what i mean with respect to kernels. An old card is likely to produce greater delays under any setup, but that is more a factor of its capabilities and quality of its parts than just purely because it is old. If you were using JACK (linux) or ASIO (windows) the delay could be minimized to some extent, but no miracles there, and that is about the most you can do. i'm only at entry level on audio engineering, but in a nutshell here is an overview to explain your delay, (latency) and my kernel related question. first of all, computers are always prone to latencies, or delays, because of the time it takes the cpu to process the audio data, read/write from disks, convert between audio signals and digital data, etc, etc. All take up cycles and valuable milliseconds. when playing normal music like mp3s in itunes and such, you wouldn't notice any delay because the data is simply read from disk and output thru speackers as they come, though technically there would be a short period between the time the data was read off disk and then heard out the speakers. in audio production that slight delay, or latency, is everything, especially when you have multi-track recording and syncing with external gear. (latencies range from under 10ms to over 100ms) Latency would be more noticeable, say when recording, and would sound like an echo if you were talking into a mic and listening thru headphones or speakers, on an average setup at least. roughly becase of the time needed to process the signal. Also, If you were to use a midi controller/keyboard connected via midi to play a software instrument, you would notice a delay between the time you hit a key on the keyboard and when you actually heard the sound. The key press transmittes midi data to the software instrument, the software triggers the desired sound immediately, but there is that slight delay to create the sound and push it out the speakers. Audio interfaces can have a latency around 5ms, which is very good, yet may still be faintly noticable, and that also depends on the power of the pc and the actual load ( number of tracks, effects, instruments playing), and latency is still a *phenomenon* and something you *have to live with* in computer audio production; as opposed to hardware gear like samplers, drum machines, synths, etc. and short of buying a $10K protools soundcard. a _hobbyist_ audio interface can be decent with latencies under 20ms. In application, multi-track recording programa like Cubase, Logic, Ardour, Ableton, Cakewalk etc, do fairly well (with a good setup) when all material is confined within the computer and not communicating with the outside world. When you are recording say a vocalist, chances are you're playing back all the other tracks (drums, bass, etc) at the same time for the vocalist to listen and sing to, plus possible playing back the vocalist with added effects likde reverb; a mixture of delays going in, and the same amount going out. Simillarly, if you had one or more audio tracks, (playing back audio recordings or samples off hard disk), and had any midi track there being sent to external hardware like a drum machine ,to play drum parts from there, or a hardware synth playing a bass or pad track, then the practice is to compensate for latency by having the midi track play or transmit with a 5ms delay, to give the computer that little time to process the audio, and so the whole mix would sound in sync (since midi to external gear to sound heard would be instant). 5ms for a sytem with 5ms latency, 20ms would require 20, 100 would require 100, etc. There is a lot more to computer audio production, but basically the efforts are always, or mainly, to reduce that latency as much as possible. Better audio interfaces not only have better components and AD/DA converters, they are also intented to take as much load off the cpu as possible, and handle what they can themselves. Also, the more power a computer has never eliminates latency or delay completely, it just generally means you can play more tracks at once and use low latencies more comfortable without dropouts, glitches, clicks and pops. ( Latency is more or less adjustable by configuring the audio buffer size and the number of said buffers to find the best setting on your system. That is, you stop at the lowest setting that works without glitches and gaps in the
Re: looking for a disk partition (slice) editor
Ah, but I do. My current problem is a case in point. I have a drive that I'm not currently using, but that has stuff on it I don't want to lose (e.g., the images of another system). I want to set it up for use. I do not want to shut everything down just so that I can set it up for use. Right now the nine or ten partitions on it include three or four (I don't remember right now) FreeBSD slices. (The FreeBSD slices are further subdivided into FreeBSD partitions, but that is irrelevant because I intend to wipe out their contents anyway.) With the exception of the partitions holding backup images of another system, nothing is arranged on that drive the way I want it arranged now, so I need to be able to rearrange it without disturbing everything else currently running on the system. There are other situations, too, that arise from time to time that I would like to be able to deal with and not have to shut down FreeBSD to do that. Anyway, back to my original question for anyone who can help: does anyone know of a disk partition editor that will allow me to manipulate the logical partitions, as well as the primary partitions, and that runs under FreeBSD? Perhaps, if there's some *good* reason why we *shouldn't* want to mess with slices while the system is running, someone can explain why. For instance -- even if I only have one HDD in the system -- we could assume a setup like this: slice / partition /etc/ partition /usr/ partition /var/ partition /usr/home/ slice C:/ slice for MS Windows primary partition Why, for the love of Gob and all that's Wholly, shouldn't I be able to wipe out my MS Windows primary partition, create a BSD slice, and use the extra space for /usr/local/share/ if I suddenly find I need the space? I, too, would like to know if a partition/slice tool such as what Scott seeks exists. In fact, it would be nice to discover such a tool that not only handles partitions/slices, but also logical/BSD partitions. -- im not sure but i think i have managed to shrink something with this http://www.gnu.org/software/parted/download.shtml please do read the documentation and disclaimer beforehand ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: xorg gfx card: amd64+xvideo+decent 2d performance
I've been trying to find anything that fits the bill. My only requirements are: * That it works with amd64 (on FreeBSD, obviously). * That it supports Xvideo. * That it has decent 2D performance. * That it works with wide screen resolutions (so I guess basically modern hardware + modern driver). Unfortunately, the 'nv' driver has significant performance issues so nVidia cards are out. I love what ATI is doing with the radeonhd driver, but no Xvideo yet. what i really want to tell u is that a modern x server runs quiet smooth with x1650 series. I'm experiencing a little slow down when opening windows but when it draws it draws fast. Videos?

compiled with gcc 4.2.1 20070719.
Logically my program is:
char *a;
char *b;
char *c;

{
a = f1(); /* malloc() and send a string */
b = f2(); /* malloc() and send a string */
c = (char *) malloc(strlen(a) + strlen(b) + 1);
c[0] = '\0';
strcat(c, a);
strcat(c, b);
free(a);
free(b);
}
When it executes free(b), my program exits with
Segmentation fault: 11. The free(a) executes well.
The problem is with free(b). Even swap free(b) first and
free(a) next, it still crashes at free(b).
If I comment out free() lines, further down the program,
first few characters of one string get dropped when executes
a completely unrelated line.
How could I bit more narrow down the problem?
Many thanks in advance.

Re: Resolution too high with 7-RC1, nVidia, xorg
Dear Xn Nooby, Im not sure if there is such a tool to edit xorg.conf file and limit the maximum resolution. In gnome desktop there is a graphical tool to switch resolution (System - Preferences - Screen Resolution) To make things obvious you will have to take a look at your xorg.conf file Please do change dir to its parent folder (cd /etx/X11/) and run cat xorg.conf | tr -s \n | grep -v # that should make your xorg.conf look simple and clear. There is a sample output below. It is a working xorg.conf Take a look at the section Screen It has Identifier, Device, Monitor, DefaultDepth options and 3 Subsections named Display for each depth where the screen resolution modes are listed: 1024 x 7 6 8 - 800 x 600 640x480 Hint: One of the following key sequence switches modes on a running server. CTRL+ALT+KP_- or CTRL+ALT+KP_+ KP_-, KP_+ (those are keypad minus or keypad plus, or gray -/+) Sincerely, Nash Section Module SubSection extmod EndSubSection Loadtype1 Loadfreetype EndSection Section Files RgbPath /usr/X11R6/lib/X11/rgb FontPath /usr/X11R6/lib/X11/fonts/misc/ FontPath /usr/X11R6/lib/X11/fonts/TTF/ FontPath /usr/X11R6/lib/X11/fonts/Type1/ FontPath /usr/X11R6/lib/X11/fonts/75dpi/ FontPath /usr/X11R6/lib/X11/fonts/100dpi/ FontPath /usr/X11R6/lib/X11/fonts/local/ EndSection Section ServerFlags Option AllowMouseOpenFail False EndSection Section InputDevice Identifier Keyboard1 Driver kbd Option AutoRepeat 500 30 Option XkbRules xorg Option XkbModel pc105 Option XkbLayout us EndSection Section InputDevice Identifier Mouse1 Driver mouse Option Device /dev/ums1 Option ZAxisMapping 4 5 6 7 EndSection Section Monitor Identifier Philips105B HorizSync 31.5 - 57.0 VertRefresh 50-100 EndSection Section Device Identifier Standard VGA VendorName Unknown BoardName Unknown Driver vga EndSection Section Device Identifier S3G IGP PRO Driver vesa EndSection Section Screen Identifier Screen 1 Device S3G IGP PRO Monitor Philips105B DefaultDepth 24 Subsection Display Depth 8 Modes 1024x768 800x600 640x480 ViewPort0 0 EndSubsection Subsection Display Depth 16 Modes 1024x768 800x600 640x480 ViewPort0 0 EndSubsection Subsection Display Depth 24 Modes 1024x768 800x600 640x480 ViewPort0 0 EndSubsection EndSection Section ServerLayout Identifier Simple Layout Screen Screen 1 InputDevice Mouse1 CorePointer InputDevice Keyboard1 CoreKeyboard EndSection - Original Message From: Xn Nooby [EMAIL PROTECTED] To: freebsd-questions@freebsd.org Sent: Tuesday, January 1, 2008 2:01:47 PM Subject: Resolution too high with 7-RC1, nVidia, xorg I am having trouble getting X to use a screen resolution that is less than the maximum. When I edit my xorg.conf to add a DefaultDepth and a Mode of 1024x768, it still comes up at 1280x1024. I did not create any modeline entries yet, since I'm not sure how to do that. My GUI (icewm) works, but browsing the web creates enormous eye-strain from the high-resolution letters. My hardware is a Dell Inspiron 530 Desktop with an nVidia Card. It comes with SATA CD's, so I have to install with FreeBSD 7-RC1. I started by running xorg -configure, and used the xorg.conf that it generated. I looked at /var/log/Xorg.0.log, and it had many entries from probing my hardware. It appears there is some kind of dynamic configuration going on, but I know its using the xorg.conf, because it got an error when I changed the adapter entry from nv to vga. I actually had a similar problem on Ubuntu, and they had some xorg-reconfigure program that would let you use less than maximum values. I was wondering if FreeBSD had something similar. The DefaultDepth 24 and Modes 1024x786 entries are from the online FreeBSD Handbook, I believe I followed the Handbook instructions properly. Am I missing something obvious? From using Linux, I was expecting the Modes values to work. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED] Never miss a thing.
