Bug in beta21

Bug in beta21

[Bruce Stephens]

This was also in beta20.  (It's these darned bug checks that were added,
I never get these messages in beta19!)

In the zsh Src directory, expanding things starting with zl:

11.36am, Thursday 20 June bommel% echo zlBUG: useheap in doexpandhist()ta21/Src
e

(I pressed TAB after the zl.)

The options:
alwaystoend autocd autopushd autoresume bgnice braceccl completeinword
correct correctall extendedglob hashcmds hashdirs hashlistall
histignoredups interactive listambiguous listtypes longlistjobs
magicequalsubst noclobber notify numericglobsort rcquotes shinstdin

This is using gcc on a Solaris (SunOS 5.4) machine.

But these bugs were there anyway.  Each time you see this a potential
memory leak may occur.

I cannot reproduce it.  You may have some compctl's which may cause that.
Please try to reproduce it starting with zsh -f, with a minimal set of
options.

I know.  It's my British dry humour.

Of course, I should have done that in the first place.  It appears
that it's not the options, but something I have in my .zshrc file to
set the titlebar of xterms.  It's something I don't like all that much
anyway (it's annoying when I'm using the scrollbar and every five
seconds zsh thwarts me because I have whatever xterm option it is
(scrollttyoutput?) set).

Here's the offending fragment:

if [[ "$TERM" = xterm || "$TERM" = aixterm ]]
then
        typeset -l titlebartime
	set-titlebar() {
		titlebartime=$(print -Pn "%D{%r}")
		print -Pn "\E]0;%~@%m   $titlebartime, %D{%A %d %B %Y}\C-g"
        }
	trap set-titlebar ALRM
	TMOUT=5
fi

I get the bug with zsh -f, and after typing in the above.  It's a bit
intermittent, but not difficult to reproduce.

You can abbreviate this to:

print -Pn "\E]0;%m:%~   %D{%A %d %B %Y}\C-g"

And it gives some other errors when expanding a dir:

~percy/BUG: permanent allocation in parsestr
BUG: permanent allocation in prefork
terb/

I was expanding on ~pe

Do you really need the title updated every 5 seconds?  I use:

        precmd() { TMOUT=600 ; title }
	TRAPALRM() { TMOUT=60 ; title }

where "title" is a function pretty much like your "set-titlebar".  This
updates the title bar between commands if I'm using the shell regularly,
otherwise it waits for 10 minutes of inactivity and then begins updating
the title bar once per minute.  The 10 minutes is enough for me to scroll
back or spend a while editing a command line without having things start
jumping around on me, and since TMOUT doesn't have any effect during the
execution of commands (only while waiting at the prompt), using precmd
actually gets the title updated more regularly than using a short TMOUT.

That's probably better.  Since I have a clock on my screen anyway,
having the time in every xterm is probably unnecessary.  Probably
using periodic and PERIOD would be better!  I used to use chpwd, but
there was some problem with that, probably the way it messed up things
like "(cd /foo; tar cf - bbb) | tar xf -".
