I am moving from asterisk 1.x to 13.6.In current implementation to dynamically register/unregister asterisk as different sip clients I use following trick: In sip.conf file I include my custom conf file which I update(add/remove) with "register =>..." and then "sip reload".
Do we have better way to do this in new asterisk version?
As variant I would like to include in sip.conf not single file but several from specific folder. Is it possible in asterisk config files?
Thank you in advance!
Asides from using realtime (https://wiki.asterisk.org/wiki/display/AST/Realtime+Database+Configuration) and sorcery (https://wiki.asterisk.org/wiki/display/AST/Sorcery+Caching), you can use "exec".
I'm not sure this is the desired way to do this, but you can take advantage of the "exec" include, see: https://wiki.asterisk.org/wiki/display/AST/Using+The+include,+tryinclude+and+exec+Constructs
So Asterisk would execute a script of yours (shell, php, ruby, etc) that will output everything you need, and there's no need to add multiple "include" statements.
For this to work you should have in your asterisk.conf:
execincludes = yes
Not performant, not pretty, might have some security issues if you are not careful, but could do the job if you don't want to use any realtime or sorcery configuration.

I have two Jenkins instances running. An old (legacy) one at version 1.614 and a new one with 1.633.
In the old one it is possible to use HTML in the job description (it even does syntax highlighting editing it). The new one doesn't. HTML content is escaped and shown as plain text. I could not find a change in the release notes explaining this behavior. Is there a configuration that I'm missing?
In the Global security menu:
Select this value to display HTML:
For enabling it via config: you have to install the configuration as code (CASC) plugin (https://plugins.jenkins.io/configuration-as-code/) , and add the following entries to your config file(s - I guess, it is better to have multiple files for a better overview):
markupFormatter:
rawHtml:
disableSyntaxHighLighting: false
If you don't need highlighting, change it to true
For example I want to automate the adding of a SAMBA share by adding a share "block" /etc/samba/smb.conf (if it is not already present), as in: https://stackoverflow.com/a/16624958/227926
...rather than have to manually edit this file.
I'd want it to detect if the block was already present too.
thoughts?
Using Shell provisioner in the Vagrantfile may be the easiest way.
See: http://docs.vagrantup.com/v2/provisioning/shell.html
Use either inline (here document) or an external shell script in Vagrantfile, to check if the block exists (e.g. use grep/ack/ag etc and check the return value $?), if NOT, add it to the /etc/samba/smb.conf.
Hope it helps.
I would like to put some of my app config data in php.ini
I tried just to add new values there and then get them with ini_get
I get nothing displayed.
Do I need to define new entries in an extension?
I know I can create a config file/ini file and easily parse it with PHP, But I want to avoid that.
I do that as I assume it is being loaded once per process.
I do not give here the big big picture, as I want to keep it as much as possible only a technical question, sadly, this platform does not allow debates.
I do need it inside the php.ini
Have you looked at get_cfg_var( config_var )?
http://www.php.net/manual/en/function.get-cfg-var.php
I believe this is for retrieving custom variables from e.g. the servers php.ini file
Don't use php.ini to configure your application, it's not the right place (as the name says, it's intended to configure php, not any application using it).
If you want to use ini files for your application's configuration, have a look at parse_ini_file()
I'm dynamically adding ssi includes based on variables and I would like to be able to have a default include in case a file doesn't exist. ie:
if /file/testthisfile.ssi exists
add /file/testthisfile.ssi
else
add /file/default.ssi
Is this possible?
Thanks!
No - I was afraid of that answer. But for anyone who might come across this question in the future I did find a work around for simple cases. You can edit the error message and in my case, output an image:
<!--#config errmsg="<img src='/file/testthisfile.jpg' alt='' />" -->
So if the file doesn't exist you can set a default.
Must underline that this will only work for simple cases, but it's a nice little work around!
Actually contrary to the answers here, SSI does in fact support file existence tests. this is the syntax
<!--#if expr="-A /private" -->
Click here to access private information.
<!--#endif -->
Support for the -A flag may need to be enabled in your apache configuration.
The expressions used in this spot of SSI have been factored out into an apache expressions module documented here
http://httpd.apache.org/docs/current/expr.html
but the -A flag is also available in "legacy" SSI expression parsers.
SSI does not support file detection.
I thought about this for a while, and indeed, ahgood was correct, SSI does not have a built-in file detection function, so flow control is limited.
As an aside, I did find a reference to an extended version of SSI (a VMS based system)
http://wasd.vsm.com.au/doc/env/env_0400.html
and there were some extensions that would allow you to check for file existence in some sort of a fashion.
However, more often then not, if one were using SSI, one would probably be running in a LAMP environment, so one could take advantage of SSI's ability to run a CGI/PHP script in the include statement.
Without too much trouble, one could resort to:
<body>
<!--#include virtual="insert_intro.html" -->
<h2>Insert An Existing File</h2>
<!--#include
virtual='checkFileExists.php?fn=insert_help.html&df=insert_default.html' -->
<h2>Insert a Non-Existing File</h2>
<!--#include
virtual='checkFileExists.php?fn=insert_no_help.html&df=insert_default.html' -->
</body>
which uses a PHP script to do all the file checking:
<?php
$theFileName = $_GET['fn'];
$theDefault = $_GET['df'];
if ( file_exists($theFileName) === TRUE ) {
include($theFileName);
} else {
include($theDefault);
}
?>
I pass two file names, the intended file and the backup/default file, the script checks for the first and if it is not found, uses the second.
This approach begs the question, why use SSI when PHP is available? In some cases, especially in a legacy system, there may be a big website based on SSI and a work-around, though less elegant, would solve a problem.
PHP is not mandatory, a PERL script would also work.
Finally, I did experiment with trying to use PHP's apache_setenv but I could not figure out how to pass environment variables between PHP, Apache and SSI (I also tried setting $_SERVER and $_ENV variables but without success).
Assuming you are running Apache 2.4 you can use the -F option (note the quoting).
<!--#if expr='-F "/private"' -->
Click here to access private information.
<!--#endif -->
From the docs (http://httpd.apache.org/docs/current/expr.html):
True if string is a valid file, accessible via all the server's
currently-configured access controls for that path. This uses an
internal subrequest to do the check, so use it with care - it can
impact your server's performance!
For the example to work the Apache user will need access to the direcotory/flag that you are testing. You may also need the following in a .htaccess or httpd.conf file:
<Directory /private>
Require all granted
</Directory>
You can do it, like this:
<!--#include virtual="/file/testthisfile.ssi" onerror="/file/default.ssi" -->
Please note that "-F" unary operator, as well as "-A" unary operator, only refer to path accessibility and not to actual existence of the resource.
Have a look here: http://httpd.apache.org/docs/2.4/expr.html (Unary operators).
Operators performing such task (-e, -s, -f) are not available under mod_include.
I was simply wondering how file watching algorithms are implemented. For instance, let's say I want to apply a filter (i.e., search/replace a string) to a file every time it is modified, what technique should I use? Obviously, I could run an infinite loop that would check every file in a directory for modifications, but it might not be very efficient. Is there any way to get notified directly by the OS instead? For the sake of demonstration, let's assume a *nix OS and whatever language (C/Ruby/Python/Java/etc.).
Linux has inotify, and judging from the wikipedia links, Windows has something similar called 'Directory Management'. Without something like inotify, you can only poll..
In Linux there is the Inotify subsystem which will alert you to file modification.
JavaSE 7 will have File Change Notification as part of NIO.2 updates.
There are wrappers to inotify that make it easy to use from high-level languages. For example, in ruby you can do the following with rb-inotify:
notifier = INotify::Notifier.new
# tell it what to watch
notifier.watch("path/to/foo.txt", :modify) {puts "foo.txt was modified!"}
notifier.watch("path/to/bar", :moved_to, :create) do |event|
puts "#{event.name} is now in path/to/bar!"
end
There's also pyinotify but I was unable to come up with an example as concise as the above.
