Not Linked - on Pi-Star Dashboard

/var/www/dashboard/mmdvmhost/functions.php
function getYSFGatewayLog() {
This is used twice in this function
| sed '/*Link/d' | tail -1`);
The /* makes everything that follows into a comment, so P25 which I want always shows "Not Linked" on the dashboard
I removed the / to make it | sed '*Link/d' | tail -1`);
and now the commented functions come to life and the dashboard now shows TG 10210 on P25
I don't use YSF so have no idea if I have broken anything in the YSF Area
A proper fix or this sure would be appreciated.

Wishful Thinking
The fix was temporary
It did however unlock a few functions that were not operable

A thought here: the NANO editor seems to have problems (gets confused) displaying (colorizing) code involving back-ticks (`). What may appear to be non-functioning code because it's colored blue may in fact be functional. So be skeptical/careful with groupings/pairings suggested by the colors.

.... and FWIW, this section of code looks "suspicious":
Code: Select all
$logLines1 = array_filter($logLines1);
if (sizeof($logLines1) == 0) {
if (file_exists(YSFGATEWAYLOGPATH."/".YSFGATEWAYLOGPREFIX."-".gmdate("Y-m-d", time() - 86340).".log")) {
$logPath2 = YSFGATEWAYLOGPATH."/".YSFGATEWAYLOGPREFIX."-".gmdate("Y-m-d", time() - 86340).".log";
//$logLines2 = explode("\n", `egrep -h "repeater|Starting|Opening YSF|Disconnect|Connect|Automatic|Disconnecting|Reverting|Linked" $logPath2 | tail -250`);
$logLines1 = preg_split('/\r\n|\r|\n/', `grep -E "onnection to|onnect to|ink|isconnect|Opening YSF network" $logPath2 | sed '/Linked to MMDVM/d' | sed '/Link successful to MMDVM/d' | sed '/*Link/d' | tail -1`);
}
$logLines2 = array_filter($logLines2);
}
if (sizeof($logLines1) == 0) { $logLines = $logLines2; } else { $logLines = $logLines1; }
return array_filter($logLines);
Like maybe it should be (line 267: $logLines2 instead of $logLines1)?
Code: Select all
$logLines1 = array_filter($logLines1);
if (sizeof($logLines1) == 0) {
if (file_exists(YSFGATEWAYLOGPATH."/".YSFGATEWAYLOGPREFIX."-".gmdate("Y-m-d", time() - 86340).".log")) {
$logPath2 = YSFGATEWAYLOGPATH."/".YSFGATEWAYLOGPREFIX."-".gmdate("Y-m-d", time() - 86340).".log";
//$logLines2 = explode("\n", `egrep -h "repeater|Starting|Opening YSF|Disconnect|Connect|Automatic|Disconnecting|Reverting|Linked" $logPath2 | tail -250`);
$logLines2 = preg_split('/\r\n|\r|\n/', `grep -E "onnection to|onnect to|ink|isconnect|Opening YSF network" $logPath2 | sed '/Linked to MMDVM/d' | sed '/Link successful to MMDVM/d' | sed '/*Link/d' | tail -1`);
}
$logLines2 = array_filter($logLines2);
}
if (sizeof($logLines1) == 0) { $logLines = $logLines2; } else { $logLines = $logLines1; }
return array_filter($logLines);

(Sorry, I misspoke: indeed it's the "/*" construct that's throwing off the editor. Thanks for pointing that out. I need to stop speed-reading posts!)

After almost a full day of playing I found the following
1) Functions.php grabs a new TG from /var/log/pi-star/P25Gateway log file
2) Changing to a new Talk Group resets the Not Linked to show the current TG
3) Keying up on the current TG does NOT reset the Not Linked
4) After approximately an hour the TG will change to Not Linked
I tryed to have functions.php write the tg to a file without success. In a stand alone script it works fine.
if (strpos($logLine,"Linked to")) {
$to = preg_replace('/[^0-9]/', '', substr($logLine, 44, 5));
$to = preg_replace('/[^0-9]/', '', $to);
$num = 0;
$myfile = fopen("/home/pi-star/p25tg.txt", "w");
$num = fwrite($myfile,$to);
fclose($myfile);
The default at time out reads the file and displays it on the dashboard instead of Not Linked
My next step is to write a bash script that will continuously monitor the P25gateway file and write Not Linked to my file when it sees Un Linked
and write the TG when it sees Linked To
It would be beneficial if the TG was written to the log file whenever the radio was keyed on the same tg.

Have you tried writing the data to a file in /tmp storage?
This snippet of code in functions.php works for me:
Code: Select all
$DMRq = "/tmp/DMRIdx.dat";
exec("grep -w -m 1 ".$callsign." ".$DMRq,$output);
if (!$output) {
exec("grep -w -m 1 ".$callsign." ".DMRIDDATPATH."/DMRIds.xtd.dat", $output);
if (!$output) {
exec("grep -w -m 1 ".$callsign." ".DMRIDDATPATH."/DMRIds.dat", $output);
if (!$output) {return "?".$callsign."?";}
$output[0] = $output[0]."\t\t\t";
}
$output[0] = strtr($output[0],",","\t");
$fp = fopen($DMRq,"a+");
if ($fp) {
fwrite($fp,$output[0]."\n");
fclose($fp);
}
}
Using /tmp takes care of the permissions and the data gets "reset" with a reboot or a delete in a nightly/daily script!

Thankyou
Writing it to /tmp solved the issue

BTW/FWIW:
This is used twice in this function
| sed '/*Link/d' | tail -1`);

I removed the / to make it | sed '*Link/d' | tail -1`);

The "/" is vital for SED to work properly; the "fix" for this is to change the "*" into its hex equivalent so the code looks "nice" in the editors and the intended functionality is maintained:
Code: Select all
| sed '/Link successful to MMDVM/d' | sed '/*Link/d' | tail -1`);
changed to:
Code: Select all
| sed '/Link successful to MMDVM/d' | sed '/\x2aLink/d' | tail -1`);
You can run this to fix it without digging through the code:
Code: Select all
rpi-rw
sudo sed -i 's/\x2aLink/\\x2aLink/g' /var/www/dashboard/mmdvmhost/functions.php
rpi-ro
Of course/as usual/in matters such as this: YMMV
Thanks for working on this gateway problem!
