ZM on FreeBSD

[abi]

I solved the mystery of 1 camera show! fcgiwrap spawns 1 children on default settings (the rc file mentions 4 workers - so I was confused until I looked into rc script deeply).

[abi]

One blocker left - Signal 4 on replay. I doubt this one as easy as fcgiwrap settings. As ZM was compiled, it simply can't contain illegal instructions ? So, this is a stack corruption ?

[Darius121]

Yes I get signal 4 on replay too

I have told it to dump cores but I can't find where it puts them.

I tried to dig in but I can't see which process is actually crashing, I only have an nph-zms process running and if I trace it I don't see it crash :-/

Any hints?

This likely means you are missing at least one Perl module. As always, execute the script from the command line (as root) to get more information.
It will tell you exactly which modules are missing.

Replay is a mode in ZoneMinder which can be one of: Single Event, Gapless Events, or All Events. However, from the context of your message this does not appear to be what you mean. Do you mean you are simply trying to play back a recorded event?

In any case, please provide the full log of the crash. More is better. It would be helpful to turn on debug and include what happens just before the crash.

Probably, I didn't looked into it yet.

Still image works. The crash is when I try to playback the recorded event. (Monitor's events -> click on event name).
I included gist with some debugging on GitHub https://github.com/ZoneMinder/ZoneMinder/issues/1357
https://gist.github.com/abishai/85541fb7e61ac61b0a8c
If this is not enough, please tell what I should provide.

Also, I'm interested in the minor issue with monitor names - http://i.imgur.com/pUUOYkE.png Looks like N is for macro used to substitute real monitor name?

And, even if my problem with 1 stream solved, I have stalled sock files with suspisious names generated every time I look the live streams. I think it will be hundreds of them in real work. Are you sure, that they really should be "soc" - without "k" ?

I inserted some debug code and looks like I found the function that crashes zms

Code: Select all

if(zm_sendfile(fileno(stdout), fileno(fdj), 0, (int)filestat.st_size) != (int)filestat.st_size) {

No return from here.

I inserted debug code there and got Signal 11 after the first Foo1 (was Signal 4 with original sources).

Code: Select all

#ifdef HAVE_SENDFILE4_SUPPORT
#include <sys/sendfile.h>

        err = sendfile(out_fd, in_fd, offset, size);
        if (err < 0)
                return -errno;

        return err;
}
#elif HAVE_SENDFILE7_SUPPORT
#include <sys/types.h>

        err = sendfile(in_fd, out_fd, *offset, size, NULL, &size, 0);
        Debug(2, "Foo2");
        if (err && errno != EAGAIN)
                return -errno;

        if (size) {
                *offset += size;
                return size;

As signal changed, I suspect. that that one is for second debug call. Something is breaking after sendfile call. More debug code is needed, but atm I have power shortage at home, so now I'm on UPS power. Cya later

OK, I built ZM with ZENDFILE disabled - now it plays.

However, I wonder what's wrong with sendfile call ? Any ideas?

I read it. That patches was accepted by upsteam mostly. The issues ZM has now are not covered by that thread.

[achix]

A ok, glad to hear that! This thread talks about 1.25, that's why I asked. Anyway, summer is approaching and normally this means ZM-time for me. Unless things get really heavy with my regular job, I might start hacking this again.

BTW, is there any official FreeBSD port made out of those patches?

I'm making one here - https://github.com/abishai/Zoneminder-port
It's almost ready, however, I'd like to solve at least one of minor issue - V4L support.

Not sure someone can help...

Found the port in FreeBSD and the github for it at
https://raw.githubusercontent.com/freeb ... ME.FreeBSD

The instructions are not too detailed, but for what I understood you'd need a FEMP, so went ahead and installed nginx, mysql-server, and php. All installed with pkg, not make from ports and all worked after installation/configuration.

Started going through the steps and saw that also needed fast cgi wraper, so installed. Noticed that instructions never starts it, so run service start on my own - not a FreBSD SME

Item # 2 starts the ZM installation with setting up sql, but doesn't mention to install ZM, so used pkg to install it from ports, but the installation broke sql and I couldn't continue:

Code: Select all

root@freebsd-1:~ # mysql -u root -p
Enter password: 
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

As mentioned above FEMP was working, including sql.

Also in the instructions:

Code: Select all

mysql -u root -p zm < /usr/local/share/zoneminder/db/zm_create.sql

Is wrong, as the path for zm_create.sql is incorrect or the installation failed and didn't move/create the file in the right directory:

Code: Select all

root@freebsd-1:~ # find / -name zm_create.sql
/usr/local/share/doc/zoneminder/zm_create.sql

Any help will be appreciated,
Al

[achix]

so used pkg to install it from ports

This is wrong. pkg != ports.

zm on FreeBSD was never easy. Try to move step by step.

I've documented the steps to install ZM on FreeBSD and FreeNAS with Abi but can't attach a pdf to this forum (invalid file extension). I've posted on the FreeNAS forum but would like to have it available here as well. Any ideas how can I make this happen?
