Mod_xml_curl – freeswitch – confluence

There is also some leaking into http://wiki.freeswitch.org/wiki/Channel_Variables , at some point that URL should also be updated. Database resume (original wiki note) This module is called when FreeSWITCH needs to fetch configuration that would normally be read from the static XML configuration files. Data recovery external hard drive mac Here are some typical use cases; If it receives a valid response from your web application, then it will load the configuration just like it would if you had put it into the FreeSWITCH Configuration File. Database management systems If it receives an invalid or 404 not found response, then it will attempt to look for the file on disk instead. Let me tell you now, the module is not perfect, and in some cases you will have to figure it out with trial and error because not everything is documented yet. You should also have a reasonable grasp on writing low latency web applications, as the performance of your web application will directly impact the performance of FreeSWITCH. 7 data recovery review Installation Edit modules.conf in your FreeSWITCH source directory, ensure the following line is uncommented, then recompile and install. Mode s database xml_int/mod_xml_curl Then edit your Modules XML Configuration File inside your FreeSWITCH configuration directory, and place the following at the top of the file; You can use the following freeswitch command to help with debugging your configuration. Windows 8 data recovery It will return a filename with the resulting XML for each xml_curl query. Java 8 database xml_curl debug_on If you get an error like the following, then that means you’re really serving up some big-time configs. Database tools No worries, just edit mod_xml_curl.c and adjust XML_CURL_MAX_BYTES as needed. Drupal 7 database api mod_xml_curl.c:121 Oversized file detected [1056100 bytes] If you want to include a local file from disk, you would use the following approach (TODO: needs confirmation); A point to note here, is to use timeout param in xml_curl config to prevent sofia profile from becoming unresponsive to REGISTER requests. Raid 6 data recovery Full explanation of this issue can be found here Pre-processor directives and variables Note: Right now, this section is based more on my evaluation of the FreeSWITCH source code than on actually using the mechanism. Database architecture I’m putting it here now while it is fresh in my mind because I believe it to be accurate. When mod_xml_curl retrieves an XML document, it saves that document to a temporary file, and then tells FreeSWITCH™ to process that file like it would process any other XML configuration file.


Iphone 4 data recovery software This means that any X-PRE-PROCESS tags you place in your dynamic configuration will be processed before handing the resulting XML to the main configuration parser, just like your conf/* files. Some care must be taken when setting variables using X-PRE-PROCESS tags. Database java Setting a variable using set in a X-PRE-PROCESS tag sets a “core global” variable. Data recovery android In all XML configuration these variables are referenced by the form $${varname}, and are actually treated as preprocessor variables. C database tutorial That is, the same parser pass that processes X-PRE-PROCESS tags also substitutes these variables for their value at that very instant in time, and the resulting xml document is passed to the main configuration parser, and that is the configuration that is used. Data recovery services cost Simply put, if you do something like this somewhat forced example: … Just pretend that is happening across two different SIP profiles so that it seems somewhat plausible. Data recovery professional The first reference to $${global_codec_prefs} will expand to mu-law, and the second one (and all subsequent references in time) to $${global_codec_prefs} will expand to a-law. Data recovery images The first setting is unchanged. This point deserves some discussion because it’s important to know that, as truly global variables, values of variables set in conf/vars.xml or in any X-PRE-PROCESS tag are accessible to the XML you generate dynamically, which makes it OK to reference $${local_ip_v4} from your generated XML and the Right thing will happen. Database management system It’s also possible to overwrite variables that were previously set in vars.xml or any X-PRE-PROCESS tag using your generated XML. Sony xperia z data recovery Doing this, however will have absolutely no effect on any previously parsed XML that used that variable. Note 3 data recovery Also, executing a reloadxml will cause the original vars.xml to be re-parsed, thus overwriting your overwrite. Database image If this sounds confusing that is because you can probably create some confusing and difficult to track bugs in your configuration by doing this. Having said all of this, we can distill the information down to the simple caveat that, while it is safe and good to reference static variables in your dynamic configuration, it is probably not safe to try to overwrite them. S note data recovery Treat them with the respect you’d treat any global variable and you should be fine. Once you start implementing things with XML cURL, you will find that several requests are fired on several different places on the code, specially with directory. Database 4d The purpose field will tell you which one it is requesting so that you know what to reply. List of data recovery software Given that the modules are the ones responsible for giving context to the information on the directory, the list of options will depend on the module. Types of data recovery On the next section, you will find examples and explanations for each one of the modules and their requests. Data recovery android app mod_sofia All sofia profiles that have parse=true on their domain definitions will query the directory for their gateway definitions. Z a r data recovery Every time we issue a rescan on a profile or the profile is loading, we will receive one of these requests. Database hacking Sometimes this request even gets sent on FreeSWITCH boot and to avoid this behavior when you only want it to send such a request purely when client sends a register then comment out the lines in the profile which goes under domains section if your not going to use under multi tenant mode. Data recovery las vegas hostname : FS-CUBO Even though we classify this as being for mod_sofia, it really is a request made by the core. Data recovery micro sd Every time the core is loading ACLs, you will get a request like the following: hostname : FS-CUBO Sample of what mod_xml_curl posts to the web server on a request for dialplan. A database is a collection of integrated and related Caller is 800 and callee is 9999, keys and values seperated by :::: • key_value (This is the filename of the configuration being requested, for example sofia.conf – note it does not have the trailing .xml extension) The response should look identical to what the file would have looked like on disk, with the exception that you need to wrap it in a , as shown in the following example; You must ensure that the “accept-blind-reg” parameter is set to “false” in sofia.conf.xml, otherwise your web application will not get called. This particular section will also be called from different contexts, and as such you may not need to return the full configuration each time. Database backend In fact, responding with as little as necessary is advisable, in order to avoid CPU spikes related to processing large XML documents, which then could lead to adverse voice quality. Gpu z database You can determine what information needs to be returned by analysing the ‘purpose’ field. Data recovery for android Example: default You will also receive requests where purpose is blank, and these are where you would send back user information, say during an authorization. If you don’t want to communicate passwords in plain text over your network, you can use the `a1
-hash` param instead. Database types Its value should be an md5sum containing ` user:domain:password`. For example, if you have a user 1002 on domain 127.0.0.1 with password 1234, you can generate the proper hash by: echo -n 1002:127.0.0.1:1234 | md5sum If your web application receives a request and you don’t wish to serve a config, then you should return the following “not found” result. Data recovery center If you return an empty response instead of the not found, you may see the following error; [ERR] switch_xml.c:1534 switch_xml_locate() Error[[error near line 1]: root tag missing] Due to the way FreeSWITCH loads modules and configuration, there are occasions where it will request a configuration in the format of ‘post_load’ One of these is post_load_switch.conf, FreeSWITCH will still attempt to request the normal file name (switch.conf) but will silently ignore the content, therefore you need to ensure that you serve the same content from both (ensuring that name attribute in reflects the requested file name). The other example of this is post_load_modules.conf, because modules.conf has to be initially loaded from disk for the module to be available in the first place. Database entry Caching If you want to reduce the amount of HTTP requests FreeSWITCH needs to make to your web server you can supply the cacheable=”true” attribute which will allow FreeSWITCH to manage a memory table with the information. Database options You will still see HTTP requests being made but should definitely notice a decrease with this attribute set. If you then make a change to the directory you should run the xml_flush_cache command to clear, some examples: # This clears items for user 1001 You may also wish to enable an expiry on the cache entries by setting the cacheable attribute to a numeirc value which would be the number of milliseconds, see http://jira.freeswitch.org/browse/FS-4871 If the the desired intent merely is to centrally store and/or share a common static dialplan with multiple FreeSWITCH installations an alternative to mod_xml_curl would be to create and use a git repository, or automatically retrieving an XML document stored on the webserver by using the exec command within an X-PRE-PROCESS. Database jokes Within your dialplan add: This method will include the dialplan stored on the server at the location where the X-PRE-PROCESS exists, the dialplan will only be fetched from the webserver on start-up and upon reloadxml.
