who calls database

From: firstname.lastname@example.org (Donald H. Mitchell)
A Symbolics tech support person asked me if I had enabled the who calls
database the other day. I said I hadn't done anything explicit and that
seemed to imply that I hadn't given their response. Wanting to find out
more I looked in my 7.2 documentation and saw that the database is
automatically enabled by Set Site. Is the documentation correct (and
thus I inferred the wrong thing from the Symbolics rep's comment)? Is
it different for 7.4?
I don't know about 7.4, but in 7.2 the who-calls database is enabled when
setting the site. However, it enables it in the :ALL mode, which means
that it only records callers in functions defined after enabling; it
doesn't go through the world building the who-calls database. If you want
all callers in the database, you must use (SI:ENABLE-WHO-CALLS
If I do :optimize world, will it automatically compress the who calls
database or do I need to do that as a separate step?
No, Optimize World doesn't do this. You have to call SI:COMPRESS-WHO-CALLS
explicitly. By the way, we've run into some problems with this recently;
it would FEP out in some worlds due to mismanagement of some GC variables.
