Feature #51 kissdx remote administration - view config feature

This feature is requested : http://www.vidartysse.net/BUGS/view_bug.php?bug_id=51 New command-line options for managing a running kissdx server from the same computer, or even from a remote host. Management functions include 

  * STOP = Stop kissdx at the enf of current file playback
  * FORCESTOP = Stop kissdx whatever any streaming occurs
  * RELOAD_CONFIG = re-read the configuration file to pick up changes.
  * GET_TXT_CONFIG =  Get current configuration loaded in memory

[edit] Context

The context is a running system on which, you just connect. What config file has been used ? what directory is currently streamed ?

Using a 'ps -aux|grep kiss' does not give an 100% sure information, because a local modification of kissdx.conf may have occured since last usage.

kissdx looks at startup a set of config file. How to know if kissd.conf or kissdx.conf has been used ? [edit] Expectation

Using another instance of kissdx to send a "GET_TXT_CONFIG" message. kissdx server receiving this command should answer with a set of "Text" oriented information. Future feature may be "GET_KML_CONFIG" to return a KML orientied information. [edit] Code analysis

config.c already contains a function to display config at startup time in console mode.

void show_current_config_Verbose(const config_settings_t *config_p)

The objective is to display content of *config pointer.

First step is to duplicate the section of 30 lines of log() to be send_config()

cons: double maintenance effort ex: log("kissdx %s is now using the following config:", KISSD_VERSION);

Second step may be a function returning an XML flow and a function to render it according text, html,kml ... kissdx release incorporating libxml2 may help managing this orientation [edit] LIST_VIDEO for kissdx in client mode

During development, it become mandatory to create a simulator to avoid the usage of KiSS player (already in use by my kids) A new administration command : LIST_VIDEO send a PCLINK-TCP:8000 command LIST VIDEO and display the result

olivier@ubuntudev:~/eclipse/workspace2/kissdx$ ./kissdx -s LIST_VIDEO -m 10.39.10.1 Admin command requested  : LIST_VIDEO kissdx Administration Client with command [LIST_VIDEO][10] LIST_VIDEO= [Déja joué|Déja joué|1|] LIST_VIDEO= [{kissdx-DIR}_local_dvdrom|{kissdx-DIR}_local_dvdrom|1|] LIST_VIDEO= [DVD_Image|DVD_Image|1|] LIST_VIDEO= [home_linux|home_linux|1|] LIST_VIDEO= [Qmultimedia|Qmultimedia|1|] LIST_VIDEO= [test|test|1|] LIST_VIDEO= [win_dvdrip|win_dvdrip|1|] LIST_VIDEO= [Indestructible.mac.xvid.divx.avi|/home/olivier/Shared_Kiss/Video/Indestructible.mac.xvid.divx.avi|0|] LIST_VIDEO= [Madonna_HungUp.mpg|/home/olivier/Shared_Kiss/Video/Madonna_HungUp.mpg|0|] LIST_VIDEO= [EOL]

[edit] GET_TXT_CONFIG : kissdx admin command

kissdx client mode ===> PCLINK://IP:8008 "GET_TXT_CONFIG ||\n" kissdx.c: main() parse command line, detect Send options with GET_TXT_CONFIG => cmdclient.c: get_txt_config() * Specific behaviour is : send string and print response 

==> cmdclient.c: deliver_tcp_cmd()            -Generic function sending 'only' a string and return the socket created
while !eof(?) print result of read(socket)    -print response

kissdx.h: which constant definition ?

kissdx server mode ===> PCLINK://IP "Text structured content of 'config' object" kissdx.c: dodaemon() * Accept ADMCMD request GET_TXT_CONFIG => cmdserver.c: handle_admin_command_gettxtconfig() 

==> cmdserver.c: send_txt_config()            -Create a text view of C structure 'config' 
 ===> connection.c: send_converted_line()     -Insert a ending "\n" (0x0A ?) and translate if needed

TODO : Each config line should be structured as PCLINK LIST_VIDEO response are


[edit] Synopsis of PCLINK protocol

Kiss Player => PcLink Server (request ) : "Param1|Param2|Param3|\n" PcLink Server => Kiss Player (response) : "Param1|Param2|Param3|\n"

Sample PcLink request  : "LIST VIDEO ||\n\r\n\r" PcLink response : "Movie.avi| /VIDEO/Movie.avi|0|\nEOL\n"

LIST VIDEO - Request Root listing request = "LIST VIDEO ||\n" Subdirectory listing request = "LIST VIDEO |home_linux/eclipse/workspace2|\n"

LIST VIDEO - Response same for "LIST PICTURE" or "LIST AUDIO" An end user movie (last entry in a tree) = Movie.avi|/home/media/video/Movie.avi|0|\n A directory browsable = kids_video|kids_video|1|\n

Others ACTION 2 /home/media/image/Hidden feature.jpg|\n => 200 SIZE /home/media/image/Hidden feature.jpg|\n => 000000000033898 GET /home/media/image/picture.jpg| 0 4096 |oqmzybpxxxxx|\n GET /home/media/image/picture.jpg| 12288 4096 |oqmzybpxxxxx|\n GET fullpath| start_position size_to_send|playerId|\n => Read 71 bytes

Admin command GET_TXT_CONFIG protocol Global config request = "GET_TXT_CONFIG ||\n" Specific config request = "GET_TXT_CONFIG |configuration_parameter_name|\n" - Global config response = (multiple line) of specific response Specific config response = Parameter_name|parameter_value_inTxtFormat|comment|\n"
