hcicyclesavemsg script not woking properly

[Hongle Sun]

Hello, We have this script running for years… just found that one outbound thread can not be processed by this script recently.. .Basically this script will check the very connection … can anyone tell me what does highlighted the statement mean?

sub ckconnStatus {

#; check connection status

open(NETCONFIG,”grep ‘^protocol’ $netconfig |”) || return 0;

@NETCONFIG = ;

close(NETCONFIG);

foreach $proc (@procs) {

open(CONNSTATUS,”hciconnstatus |grep ‘^$proc ‘ |”)

  || die “Cannot access hciconnstatus”;

 $procpath = $rootpath . “/” . $site . “/exec/processes/” . $proc;

while () {

chop;

if (/^S+s+(S+)s+ups+S+.*$/) { ($conn) = $1;

foreach (@NETCONFIG) {

$NCline = $_;

chop($NCline);

if ($NCline =~ /^protocol ($connS*).*$/) ($conn) = $1;

  printf(“nProcessingn    Root: %s, site: %s, proc: %s, thread: %sn”,$rootpath,$site,$proc,$conn);

last;

}

}

&ckSavemsgs;

}

}

close(CONNSTATUS);

  }

return 1;

}

Thanks

It is pattern matching that is searching the results of hciconnstatus, such as:

adt    to_ecl_ip_a    up   up   Tue Feb 19 16:23:02

and returning the various columns listed above.

It is applying it as such:

(/^S+s+(S+)s+ups+S+.*$/) { ($conn) = $1;

^ is anchoring the pattern match to the beginning of the line

The first S+ is searching and will match any non-white space.  It will result in a match on “adt” in the output listed above.

The first s+ is searching for and wil match any white space.  It will match the space between the first and second column.  

The second S+ (in parantheses) will match whatever is listed in the second column which is the connection name. The parantheses around it means that it will take whatever the S+ returns (in this case, the connection name), and place it in a variable.  The variables returned by these are labeled as $1, $2, $3, and so on.  In your case, it is taking the connection name and placing it in the variable $1, which your script turns around and sets the variable $conn with it.

The other s+ is returning the whitespace between the columns.

The word “up” is looking for the literal word up in the next column.

The .* will match anything at the end.

Hope this helps a bit….

Any way to adjust this type script if the thread name is too long and isn’t fully display by hciconnstatus?

I would create another version of hciconnstatus and just change the formatting of the output string.

Here’s the snippet that I changed in my version:

set hfmt “%-20.20s %-50.50s %-10.10s %-15.15s %-20.20s” ;# Heading format

set fmt “%-20.20s %-50.50s %-10.10s %-15.15s %-20.20s” ;# Output line format

Hope this helps.

We have modified the following line in both hciconnstatus and hciprocstatus to allow longer names.

set fmt “%-32.32s %-32.32s %-10.10s %-15.15s %-20.20s” ;# Output line format

Works well

Instead of modifying hciconnstatus why not simply use msiAttach?

Or you can grep the names right out of NetConfig:

    grep protocol NetConfig | cut -f 2 -d ” “

Why do we always make it so hard  😀

Well Charlie, my car is running rough, so I should replace the engine, right?

I like the way you think!
