Hi,
I have the same result as yours. After adding listing command as
runscript console command, Bacula throws segmentation violation.
I researched this problem. It seems that in:
/usr/src/bacula-5.2.12-new/src/cats/sql.c lines 636-642:
Dmsg0(800, "list_result finished first loop\n");
if (type == VERT_LIST) {
goto vertical_list;
}
Dmsg1(800, "list_result starts second loop looking at %d fields\n",
num_fields);
list_dashes(mdb, send, ctx);
^^^
variable ctx is broken, so it is not able to run list_dashes() without error.
It looks like runscript directives were designed for run shell
scripts/programs or bconsole commands which do not show results in
tabular output. It makes sense.
Summing, you found bug in Bacula.
I prepared patch for this. It blocks running bconsole output for
runscript. It works for me but I am not C++ programmer. Finally it
does not cause segmentation violation and Director crash. I am
attaching it to this message.
For your solution I think that better will be to put your bconsole
requests in a shell script.
