so-called pipe files (sh-np-*) do not get deleted when processes close.

[Michael Felt]

Hi,




```


```

back to ksh:
```
$ cat ~/build.log


```



I have forced some debug info:

a) unset USE_MKTEMP
b) added the PID of the process creating the special file
c) additional debug info using fprintf(FILE, ...)




That gives me the following information from the command above:


27918500:../src/bash-5.0.18/subst.c:5506:reap_procsubs-calls:23

26869806:../src/bash-5.0.18/subst.c:5506:reap_procsubs-calls:23


And this is remaining:
$ ls -l /tmp/sh-np* | grep 21233868





Thanks for any assistance.

Regards,

Michael

Issue: AdoptOpenJDK build process makes bash calls in a particular way. An abbreviated (shorter pathnames) example is: bash-5.0$ /usr/bin/printf "Building targets 'product-images legacy-jre-image test-image' in configuration 'aix-ppc64-normal-server-release'\n" > >(/usr/bin/tee -a /home/aixtools/build.log) 2> >(/usr/bin/tee -a /home/aixtools/build.log >&2) Building targets 'product-images legacy-jre-image test-image' in configuration 'aix-ppc64-normal-server-release' Building targets 'product-images legacy-jre-image test-image' in configuration 'aix-ppc64-normal-server-release' I added some debug statements to try and catch what is not happening. It seems that the fifo_list[i].proc value is never being set to (pid_t)-1 so any call to `unlink_fifo()` or `unlink_fifo_list()` does not unlink the special file created.     fprintf(unlink_lst,"%d:%s:%d:%16s:%2d:%12d:%s\n", getpid(), __FILE__, __LINE__, "unlink_fifo_list", i, fifo_list[i].proc, fifo_list[i].file); 25231596:../src/bash-5.0.18/execute_cmd.c:752:execute_command_internal:/usr/bin/printf "Building targets 'product-images legacy-jre-image test-image' in configuration 'aix-ppc64-normal-server-release'\n" > >(/usr/bin/tee -a /home/aixtools/build.log) 2> >(/usr/bin/tee -a /home/aixtools/build.log >&2) 21233868:../src/bash-5.0.18/subst.c:5372:   add_fifo_list: 0:           0:/tmp//sh-np-21233868-1115804781 27918500:../src/bash-5.0.18/execute_cmd.c:752:execute_command_internal:/usr/bin/tee -a /home/aixtools/build.log 21233868:../src/bash-5.0.18/subst.c:5372:   add_fifo_list: 1:           0:/tmp//sh-np-21233868-3761770506 27918500:../src/bash-5.0.18/subst.c:5510:   unlink_if==-1: 0:           0:/tmp//sh-np-21233868-1115804781 26869806:../src/bash-5.0.18/execute_cmd.c:752:execute_command_internal:/usr/bin/tee -a /home/aixtools/build.log 1>&2 26869806:../src/bash-5.0.18/subst.c:5510:   unlink_if==-1: 0: 27918500:/tmp//sh-np-21233868-1115804781 26869806:../src/bash-5.0.18/subst.c:5510:   unlink_if==-1: 1:           0:/tmp//sh-np-21233868-3761770506 prw-------    1 aixtools staff             0 Mar 11 08:07 /tmp/sh-np-21233868-1115804781 prw-------    1 aixtools staff             0 Mar 11 08:07 /tmp/sh-np-21233868-3761770506 Getting back to AdoptOpenJDK - a build process has roughly 3750 of these commands - leaving 7500 files behind in /tmp. On a busy day this can lead to over 100k empty files in /tmp.
