Doug,
I'm confused as to how you managed to *not* leak when I'm still
leaking. I've tried these tests on both a Solaris 2.7 system and
a Linux 7.1.
Here is a summary of what I do:
I build Perl
./Configure -des -Uusemymalloc -Dprefix=$(echo ~/test/prefix) -Dcc=gcc
make && make test && make install
I build Apache
~/test/prefix/bin/perl Makefile.PL USE_DSO=1 EVERYTHING=1 \
USE_APACI=1 APACHE_PREFIX=$(echo ~/test/prefix/apache) \
APACHE_SRC=../apache_1.3.19 \
APACI_ARGS='--enable-module=all --enable-shared=max' \
DO_HTTPD=1
make
make test
I now run the test:
make start_httpd_fork
ps -o 'pid,vsz,comm' -p $(cat t/logs/httpd.pid )
kill -USR1 $(cat t/logs/httpd.pid )
ps -o 'pid,vsz,comm' -p $(cat t/logs/httpd.pid )
kill -USR1 $(cat t/logs/httpd.pid )
etc. The virtual size grows each time, although by different amounts
in Linux and Solaris. Both are around 4Mb. So what are you doing
differently? Let me know so I can do the same thing. The Perl I'm using
is 5.6.1 and the modperl is
modperl_20010614113010.tar.gz.
-P
