I am following this guide to run my C++ code in micropython environment, the normal/simple C++ code works on my ESP32 board but when i try running big loops it gives an error.
The error:

Bye bye. Have a nice day!!!

My aim is to obtain lines containing ActivationStatus and VoipServiceStatus.
So I wrote this script
#!/usr/bin/expect -f
set timeout 2
set ip_addr [lindex $argv 0]
set OUTFILE "voip_status.log"
spawn telnet 172.16.11.$ip_addr
expect {
timeout { send_user "\nFailed to get login prompt for $ip_addr\n"; exit 1 }
eof { send_user "\ntelnet failure for server $ip_addr\n"; exit 2 }
"*Login:"
}
#expect "*Login:"
send -- "user\r"
expect "*Password:"
send -- "user\r"
expect ">"
send -- "voice show\r"
expect ">"
set voice_full_output $expect_out(buffer)
set voice_stat_lines [ split $voice_full_output "\n" ]
foreach line $voice_stat_lines {
if {[string match "*VoipServiceStatus*" $line]} {
set timestamp [timestamp -format %Y-%m-%d_%H:%M:%S]
set chan [open $OUTFILE a+]
#puts "ok - MATCH $line"
puts $chan "$line $timestamp"
close $chan
}
if {[string match "*ActivationStatus*" $line]} {
set chan [open $OUTFILE a+]
#puts "ok - MATCH $line"
puts $chan "$line"
close $chan
}
}
send -- "exit\r"
expect eof
Here is my output
$ cat voip_status.log
ActivationStatus : Enabled
2021-03-17_11:32:35tus : Up
ActivationStatus : Enabled
2021-03-17_11:32:35tus : Up
As you can see that time stamp has overwritten the line I had filtered out.
I wanted timestamp to appear at the end of line .
Why is this happening ?
Here I made an experimental setup which anybody can run to see this behaviour.

Here is the output file you will get

ActivationStatus : Enabled
2021-03-17_12:27:11tus : Up
Thanks.
If you look at the output file using cat -vet it shows the non-printing control characters, tabs, and end-of-line, and you get:
ActivationStatus : Enabled^M$
VoipServiceStatus : Up^M 2021-03-17_09:02:53$
You can see ^M in the middle of a line, which is carriage-return. On a terminal this makes the cursor go back to the start of the line, and start overprinting.
This is the typical result of spawn, which runs a command through a pty, which alters each output newlines into carriage-return and newline. This is normal and desired for a pty. You can either turn it off (see stty -onlcr), or knowing that it is likely to be there, you can remove it in your script: after the foreach ... line, trim the variable $line to remove \r:
set line [string trimright $line "\r"]
I am trying to load 2k records on azure service bus queue through informatica, but getting timeout exception. The connection is working file for 700 records, successfully loading on queue.
I have created JMS and JNDI connection and is working fine if number of records are less.

Appreciate the help.
The queue size for azure was 1GB but it seems that Azure service bus queue can only accept 100 messages in one transaction. I was able to solve the issue by changing the properties at informatica session level.
Commit type to "Target"
commit interval to "100"
And in target properties kept the JMS priority to 9.
I wanted to get do_sys_open filename argument as string. For this i added kprobe following kprobetrace.txt. A simple probe which gives filename as hex works for both x86/arm64.
x86: echo 'p:myprobe do_sys_open filename_string=%si' > kprobe_events
arm64: echo 'p:myprobe do_sys_open filename_string=%x1' > kprobe_events
However changing probe to get string for file name works on x86 but not arm64(ie cannot get string representation filename_string=(fault))
x86:
echo 'p:myprobe do_sys_open filename_string=+0(%si):string' > kprobe_events
output:
adb-30551 [001] d... 4570187.407426: myprobe: (do_sys_open+0x0/0x270) filename_string="/dev/bus/usb/001/001"
arm64:
echo 'p:myprobe do_sys_open filename_string=+0(%x1):string' > kprobe_events
output:
netd-4621 [001] d... 8491.094187: myprobe: (do_sys_open+0x0/0x24c) filename_string=(fault)
To check if i was using arm ABI correctly i tried setting probe using perf.
The probe created by perf as seen from /sys/kernel/debug/tracing/kprobe_events was similar
./perf4.14 probe 'do_sys_open filename:string'
/d/tracing # cat kprobe_events
p:kprobes/myprobe do_sys_open filename_string=+0(%x1):string
But perf probe was also failing (ie filename_string="") in this case.
./perf4.14 record -e probe:do_sys_open -aR sleep 3
/data/local/tmp # ./perf4.14 script
perf4.14 4587 [007] 7490.809036: probe:do_sys_open: (ffffff8337060148) filename_string=""
sleep 4588 [003] 7490.817937: probe:do_sys_open: (ffffff8337060148) filename_string=""
What would be the correct way to set kprobe_events for arm to fetch args as string?
Am i using the ABI incorrectly?
On kernel version >= 4.20, you can use $argN to fetch the Nth function argument. From kernel 4.20 kprobetrace.rst:
FETCHARGS : Arguments. Each probe can have up to 128 args.
.....
.....
$argN : Fetch the Nth function argument. (N >= 1) (\*1)
Since the filename is second argument of do_sys_open(), you should give $arg2 in the kprobe event, like this:
echo 'p:myprobe do_sys_open filename_string=+0($arg2):string' > kprobe_events
This should work on both x86 and arm64.
