gutza / octave-daemon Goto Github PK

It looks like the max_instances configuration value is ignored and octave-daemon always launches 3 children.

Can you please create a new release, for example 1.1.0 or something?

I'm new to github, so tell me if this isn't the right spot for this post. I am using the octave-daemon in a web thing right now. I've been trying to grind through the different classes in http://projects.moongate.ro/octave-daemon/ to figure out if there is a way to use a simple function like ->run('plot(1:10)') or ->query('plot(1:10)') to output a plot for some diagnostics im running, and possibly just output the files onto a window. Wondering if this is accounted for.

i have a .m file which contains the octave code.i want to run this .m file through php.
how shld i call this file?? exec() function doesnt help>

I'm trying to use octave daemon (https://github.com/Gutza/octave-daemon) with php on my CentOS. I downloaded and run the install. The daemon was installed to usr/bin. When I want to start the daemon service, it complain error posix missing. I solved the error by doing yum install php-process. I restarted my apache and tried again. Now, I get error

PHP Fatal error: Uncaught exception 'RuntimeException' with message 'Failed starting controllers! Check the system logs for more information.' in /usr/bin/octave-daemon:32 Stack trace:

0 {main}
Please advice what I can do. It's urgent. Thanks!

the following returns zero array size

$i = self::$octave->getMatrix("eye(3)");
$octave_sum = sizeof($i);

I am having an experiment, I need to run the same command like 30 times at the same time (coming in via multiple requests). How this daemon will be able to handle this? Should I configure 30 child instances in the config file for this? What if I send in more requests like 40 requests while the max child is 30?

My php script runs an octave script through the daemon. works well.
I added a urlread webservice call inside the octave script (just returns hello world).
s=urlread("localhost:8000/hello");

the browser hangs until I kill the daemon.

any clues why?

Thanks Gutza

Has anyone tested this library with Octave 4?

I'm receiving a strange error at https://github.com/Gutza/octave-daemon/blob/master/include/classes/Octave_controller.php#L315

with message

[ErrorException]
  Undefined offset: 0

Installing on Centos 6.2 gives me the following error:

-bash: ./install: /usr/lib/php: bad interpreter: Permission denied

Changing the first line in the install script to #!/usr/local/bin/php let me install the daemon.

However, running the service has the same error.:
service octave-daemon start
Starting GNU Octave daemon (octave-daemon): /bin/bash: /usr/bin/octave-daemon: /usr/bin/php: bad interpreter: No such file or directory

There should really be an option to select WHERE your PHP installation is located.

Can you add a composer.json file to this project and than add it to packagist.org so library can be installed via composer?

If composer is black box for you I can prepare a sample file if you need.

starting the daemon throws an uncaught exception:

Can you please create a web hook for Packagist, so the github will automatically tell when the new release?

The manual for doing this is here https://packagist.org/about#how-to-update-packages
Check section "GitHub Service Hook".

Hi,

I am running a vagrant box.

the following works fine:
nohup octave-daemon -d -c /etc/octave-daemon.conf&

from the quick start examples, the following works great in /var/www/html/test.php without even starting the daemon:
require "Octave_lib.php";
$octave=new Octave(false);
echo "Result=".$octave->query("1+2");

however, the following fails:
$octave=new Octave("127.0.0.1);

the same code fails when placed in a php class (symfony Controller). says Command did not run successfully on line "new Octave"

what are the fixes?

Notice: Undefined offset: 0 in /opt/lampp/htdocs/vendor/gutza/octave-daemon/include/classes/Octave_controller.php on line 317

Fatal error: Maximum execution time of 100 seconds exceeded in /opt/lampp/htdocs/vendor/gutza/octave-daemon/include/classes/Octave_controller.php on line 369

this error is obtained when we try to run a php file through localhost (xampp)
help!!!!reply asap. :)

When I am starting the service from the terminal with:

service octave-daemon start

the errors I am facing are

/etc/init.d/octave-daemon: line 14: /etc/rc.d/init.d/functions: No such file or directory
Starting GNU Octave daemon (octave-daemon): /etc/init.d/octave-daemon: line 29: daemon: command not found

The first error occurring at line 14 is related to the call " source /etc/rc.d/init.d/functions ". Such directory has not been created during the installation.

is this the right way to access a matrix element? i get an error:

$result = $octave->getMatrix("eye(3)");
$octave_sum = $result[0][0];

Hi Gutza,

Is there an example around handling structures returned from Octave?

for example,

function x = fn()
x.a = 1;
x.b = [1, 2; 3, 4];
x.c = "string";
endfunction

thanks
