Packaged exe is not executing in a specific scenario #1241
Description
I have built an executable using pkg command ---> lets call it process B.
Scenario:
We have 2 processes
- Process A (in C#)
- Process B (Generated using pkg command to run js code)
Runtime:
"Process A" starts "Process B".
Process B stops Process A, executes some business logic, and then restarts Process A.
The above 2 steps are repeated every hour.
Problem:
First time when Process A starts Process B, it works as expected.
But next time when the Process A tries to start Process B, it only open the node console. It does not execute the JS file.
Observation:
- When I manually run .load "pathtojs/abc.js" on the opened node console, it works fine.
- While starting Process B from Process A, if I pass the path of the js file, it works fine, however
in first iteration, js path is coming as a process argument to my JS process
but in subsequent iteration, js path is not coming as argument, which essentially means, in subsequent iterations the started
process is just node console

Sanitize the environment variables before you launch pkg executable from a pkg-launched program.
Specifically
PKG_INVOKE_*.pkg adds it when it launches another program, to allow executing sub programs and avoid infinite loop.
The executed program inherited the variables, will pass it to programs launched by it, and pkg will hit the kill switch.

Thanks Jesec !! I printed and compared the environment variables in the first cycle and the subsequent cycles. I found one additional environment variable in subsequent cycles, I.e. PKG_EXECPATH.
when I reset it to null in subsequent cycles it works absolutely fine.
Now my doubt is whether any additional environment variable I need to check (although I don’t find any additional variable starting from PKG_ except the one I mention d above).
PS: it’s a windows environment
