Bug or WAD? Midnight Commander F10 different in xterm than native or rxvt

Bug or WAD? Midnight Commander F10 different in xterm than native or rxvt

[Peter Farley]

I don't know if this is the right place to ask this question, but if it is not please advise me where to send it.

Midnight Commander exits with F10, and in a native bash window or rxvt F10 exits to the last directory viewed.  In an xterm though, it exits to the original directory from which MC was started.

Do you think this a bug in MC or is it WAD?  If you think it's a bug in MC I will gladly debug it myself, I just want to know if it's WAD for xterm's first.

I am using a fresh cygwin + cygwin/X install on WinXP SP3, and I will supply the usual problem report documentation if needed to answer my question.

Regards,

Peter

Sorry, I don't know anything about MC really but isn't there some doc on
it that describes what F10 is supposed to do?

on my Win-XP SP2 under cygwin/X 
MC with F10 exits in the current directory

Peter,
as mc is an alias
alias mc='. /usr/share/mc/bin/mc-wrapper.sh'

I guess that under X this wrapper is working 
differently than under console

---------------mc-wrapper.sh------------------
MC_USER=`id | sed 's/[^(]*(//;s/).*//'`
MC_PWD_FILE="${TMPDIR-/tmp}/mc-$MC_USER/mc.pwd.$$"
/usr/bin/mc -P "$MC_PWD_FILE" "$@"

if test -r "$MC_PWD_FILE"; then
        MC_PWD="`cat $MC_PWD_FILE`"
        if test -n "$MC_PWD" && test -d "$MC_PWD"; then
                cd "$MC_PWD"
        fi
        unset MC_PWD
fi

rm -f "$MC_PWD_FILE"
unset MC_PWD_FILE
------------------------------------------------

Regards
Marco

Marco,

Thanks, but in my xterm "which mc" returns "/usr/bin/mc", which is an "exe" and not an alias to the wrapper shell script.

Executing "/usr/bin/mc" from an xterm prompt produces the same result, it exits to the MC invocation directory instead of the current one.

Thanks for pointing out that wrapper script though.  Most interesting.

Peter

Yes, there is, from the "info mc" pages:

"       Quit (F10, Shift-F10)

       Terminate the Midnight Commander.  Shift-F10 is used when you want to quit and you are using the shell wrapper.  Shift-F10 will not take you to the last directory you visited with the Midnight Commander,  instead it will stay at the directory where you started the Midnight Commander."

I am not using the "wrapper" shell script, as far as I can tell (but I'm still looking hard to see if I am wrong about that).  Simple F10 in an xterm though *always* exits to the original directory.  "Shift-F10" has no effect at all inside of MC from an xterm in the testing I have done (nor do Ctrl-F10 or Alt-F10).  I guess it's *possible* that there is a bug that makes MC *think* it sees "shift-F10" when only simple "F10" was pressed, but that remains to be proven.

I will have to run a debugging version of MC with gdb to see the difference between xterm and non-xterm behavior.  I will report back when I have done that experiment.

It might be a while, but I will report back.

Thanks for your help and advice.

Peter

Perhaps more likely, the alias isn't setup by the shell init scripts under 
xterm because of the way the xterm was started (which the OP hasn't said) (but 
is being setup for cmd.exe or rxvt)

Note that it's impossible for mc to change the current directory of the parent 
shell without this alias.

For the record, the xterm I used for this test was the one started from the cygwin-X start menu item.

I still have not found the round tuits to compile a debugging version of MC to check this out in more detail, but I hope to do so sometime in the next 30 days (lots of RL intruding).

I will reply again when I have more information.

Thank you all for your advice and help.

Peter
