In the context of a 10.6 server running as a web app, I’m trying to implement a function that uses the process module to run commands to get information
about the running BaseX servers, in particular, the PID and port each server is on. I start a number of “worker” BaseXHTTP instances to handle long-running processes.
On Linux this code works:
let $cmdResult := proc:execute(‘ps’, ('-o', 'pid,%cpu,command'))
From which I can parse out the PID and port for BaseX processes:
let $lines as xs:string* := ($cmdResult/output/text() => tokenize('
'))
return
map{
'data' :
let $servers as map(*) := map:merge(
for $line at $p in $lines[contains(., 'BaseXHTTP')]
let $pid as xs:string := tokenize($line, '\s+')[1]
let $port as xs:string := tokenize(substring-after($line, ' -p'),'\s+')[1]
return map{ $port :
map{
'port' : $port,
'pid' : $pid
}
}
)
return $servers
}
However, on macOS there’s not an exact equivalent of the linux version of ps, but there is the “pgrep” command, which, from the command line, lets
me get the data I need:
pgrep -lf basex
However, when I try to run this from within BaseX, I get “sysmon request failed with error: sysmond service not found pgrep: Cannot get process list”
I assume this is a function of how the HTTP servers are running on macOS. I’m starting them like so:
"${basexBinDir}/basexhttp" ${debugFlag} -S -p${clientPort} -h${httpPort} -s${stopPort} &
So as a service
Any ideas how I might make this work on mapOS?
Thanks,
Eliot
