I'm trying to increase usabilty for my scripted project-, for that i wanted to apply an error message poping up upon every and any error (other than proper exit) indicating the enduser a uniform, and hopefully readable error messsage.
To achieve this, i wrote a msg_error function, and prepared some trap handling...
Code:
msg_error() { # CALLER SCRIPT FUNCNAME LINENO [CONTENT]
# Prints an error message and exits
#
caller="\$1" script="\$2" fname="\$3" lineno="\$4"
shift 4
content=($(echo "\${@}"))
printf '\r\t%s:\t%s\n' \\
"$(gettext 'Caller of script')" "\$caller" \\
"$(gettext 'Scriptname')" "\$script" \\
"$(gettext 'Functionname')" "\$fname" \\
"$(gettext 'Linenumber')" "\$lineno"
for cont in "\${content[@]}";do
printf '\t%s\n' "\$cont"
done
trap − INT QUIT TERM EXIT
exit 1
}
Code:
#
# Traps & Error messages
#
traps_save(){ saved_traps=\$(trap) ; export saved_traps ; }
traps_restore() { eval \$saved_trap;}
export -f msg_error traps_save traps_restore
# Set and save basic error message traping,
trap "msg_error \${CALLER:-$0} \$0 \${FUNCNAME:-NON-FUNCTION} \$LINENO 'Args: \$@' " HUP INT QUIT ABRT KILL ALRM TERM ## 1 2 3 6 9 14 15
traps_save # Save initial traps
My issue isnt this... well at least not really..
My issue is the follow up, when callling a script with the same name (but which is intended to be executed, while this generated script is ment to be sourced).
Code:
0 ~/prjs/tui $ export LC_ALL=C
0 ~/prjs/tui $ ./make ; sudo ./make-install ; sh ./tuirc ##(this is /etc/tuirc)
0 ~/prjs/tui $ bash -x $(which tuirc) ## (this is /bin/tuirc)
+ tui-print -H 'TUI (0.9.4-inprogress), Copyright (c) 2015 by sea' 'Simon Arjuna Erat (sea), 08:02:02 2015-12-26'
/etc/tuirc: line 129: trap: TUI (0.9.4-inprogress), Copyright (c) 2015 by sea: invalid signal specification
/etc/tuirc: line 129: trap: Simon Arjuna Erat (sea), 08:02:02 2015-12-26' : invalid signal specification
<..>
1 ~/prjs/tui $ which tuirc
/usr/bin/tuirc
So the search for one of the errrors ($'\212.... not found) became more complicated than expected...
Code:
cat -n /etc/tuirc | grep 129
129 trap "msg_error ${CALLER:-$0} $0 ${FUNCNAME:-NON-FUNCTION} $LINENO '$@'" INT QUIT TERM
## HUP INT QUIT ABRT KILL ALRM TERM ## 1 2 3 6 9 14 15
I dont understand where the invalid signal spec comes from?
Specialy since calling the /etc/tuirc script by itself, it closes without error, but sourcing from other files, it raises one, in way i cant follow the reason.
Any ideas or advices please?
Thank you in advance.
I'm confused. The title of this thread is "[BASH] Errormessages and Traps with a 'here-doc'", but I don't see any here-documents anywhere in the code you've shown us?
the standards say that setting a trap for SIGKILL produces undefined results. So you might want to try this without the KILL parameter. (There is no way for any process to catch a SIGKILL signal.)
In fact you quoted parts of the 'here-doc', but you're right it isnt obvious.
Thought it was, due to the escapes.
Also, seems i was editing my post while you wrote the answer, i've already removed the 'kill' signall, with no change.
Sorry about that.
The traps_{save,restore} arent (really) used yet (outside of that script).
As of now (past, until now), the generated ./tuirc did only contain TUI_DIR_{variables}, and the injection_protection.
Which was sourced by the already existing and hardcoded ./bin/tuirc. (which is either sourced or executed - to config, etc).
End goal is to replace the current hardcoded ./bin/tuirc with the generated ./tuirc which - as soon it works - will become the ./bin/tuirc.
But i guess this is only relevant to me.
Anyway, here's the full script: ./scripts/gen-tuirc.sh
NOTE: the commented out cat tuirc.tpl results in an endless loop, as the *tpl was not adjusted to the recent changes (it still sources 'itself' as its origin is/was bin/tuirc).
Also, all the functions/variables of the *tpl file are already present in the executed (not visible here) bin/tuirc.

Simple said, the only NEW parts are msg_error and everything below until EOS.
Changing back there helps, to get rid of the 'invalid signal' messages.
However, these remains:
Code:
/usr/bin/tui-print: line 1: $'\342\210\222': command not found
I do know i've used 'somewhere' 'something like' (pseudo code): $'var'
But me cant find that anymore...
Code:
0 ~/prjs/tui $ grep "\$\'" */*
bin/tui-ftp: NUM=$$
bin/tui-log: NUM=$$
bin/tui-tar: $showBar && tui-progress -rbm $size_tarball -i $$
bin/tui-tar: $showBar && tui-progress -rbm $org_size -i $$
grep: docs/samples: Is a directory

By now i still have no idea why the invalid signals occour, or why i cant find the $' in any scripts...
Any ideas or advice from here?
Thank you in advance.
/usr/bin/tui-print: line 1: $'\342\210\222': command not found
doesn't mean that bash was trying to execute something specified using $'...', it just means that it was asked to execute a command whose name was specified as those three octal valued bytes (which do not form valid characters in the current locale), and there was no command found in $PATH matching that name. Try:
Code:
grep $'\342' ...
instead of:
Code:
grep "\$\'" ...
and if that doesn't work either, try looking for a lowercase letter b followed by a backspace. (If the last one works and you don't see why I made that wild guess, ask me after it works.)
Note that if you have something like:
Code:
$var
in your code somewhere such that it is being treated as a command name, it might be even harder to find. (Like maybe the double backslashes in the printf statement in msg_error() are causing the output from the getconf command substitutions to be executed???)
As always, bash -xv script [arg...] is your friend when trying to find out where something is going wrong.
For the record, you still have:
Code:
trap − HUP INT QUIT ABRT KILL ALRM TERM EXIT
in your script. And in the two lines in your code:
Code:
for tc in /usr/var/tmp /var/tmp /tmp $HOME/.cache;do [ -w "$tc" ] && break;done
for tl in /usr/var/log /var/log $HOME/.config/tui/logs;do [ -w "$tc" ] && break;done
I would have guessed that the tc marked in red above should be tl.
This User Gave Thanks to Don Cragun For This Post:
Was great, figured during copy paste of a trap example, i copied − and didnt change to - .
So we're back to the wrong signal.
I tried to provide the 2 most essential parts, around the loading of the generated rc file (see above), and the (still the same) errors where the actual output happens.

As the userinput was 'n', which was taken as a trap signal, i'm more confused on this subject than ever.
I removed 'INT' now, since i belive ctrl+c should not raise an error message.
Just to verify if 'everyting else' is working properly, i've redirected stderr to null "temporary".

As in this example: <cmd> || msg_error [args...]
