parallel bug in pidtable

[Harvey, Douglas (RIS-MDW)]

Hi there. I recently ran into a bug in this program.

 

This command “parallel echo ::: A B C ::: D E F” produced this output:

 

---

parallel: This should not happen. You have found a bug.

Please contact <parallel@gnu.org> and include:

* The version number: 20151122

* The bugid: pidtable format: 14271 14269

 

* The command line being run

* The files being read (put the files on a webserver if they are big)

 

If you get the error on smaller/fewer files, please include those instead.

This utility had worked (great) in the past so was surprised by it. I’ve written perl previously so debugged it and found the process that was causing the problem:

 

ps -U yuryan01 -Hfww

UID        PID  PPID  C STIME TTY          TIME CMD

yuryan01 14269     1  0 Dec11 ?        00:00:00 SCREEN -t MRC

yuryan01 14271 14269  0 Dec11 pts/252  00:00:00

yuryan01 14274 14269  0 Dec11 pts/255  00:00:00   /bin/bash

yuryan01 20507 14269  0 Dec11 pts/31   00:00:00   /bin/bash

 

Once I deleted that process, parallel works again. PID 14271 was a bash session, I don’t know why the command name no longer showed up, but it wasn’t hung or in some other crazy state.

 

Anyway, thought I would let you know and also congratulate you on a fine program. Works very well.
