Dear maintainer,
I have noticed that most time of 'make index' on my system takes a grep for
libssl.
The following is done while 'make index' was running.
$ ps axww | grep libssl
23119 p1 IN+ 0:00,00 sh -c grep -l -r "^lib/libssl.so." "/var/db/pkg" |
while read contents; do sslprefix=`grep "[EMAIL PROTECTED] " "${contents}" |
/usr/bin/head -n 1`; if test "${sslprefix}" = "@cwd /usr/local" ; then echo
"${contents}"; break; fi; done
23124 p1 DN+ 0:00,84 grep -l -r ^lib/libssl.so. /var/db/pkg
23125 p1 IN+ 0:00,00 sh -c grep -l -r "^lib/libssl.so." "/var/db/pkg" |
while read contents; do sslprefix=`grep "[EMAIL PROTECTED] " "${contents}" |
/usr/bin/head -n 1`; if test "${sslprefix}" = "@cwd /usr/local" ; then echo
"${contents}"; break; fi; done
24555 p1 IN+ 0:00,00 sh -c grep -l -r "^lib/libssl.so." "/var/db/pkg" |
while read contents; do sslprefix=`grep "[EMAIL PROTECTED] " "${contents}" |
/usr/bin/head -n 1`; if test "${sslprefix}" = "@cwd /usr/local" ; then echo
"${contents}"; break; fi; done
24556 p1 DN+ 0:00,41 grep -l -r ^lib/libssl.so. /var/db/pkg
24557 p1 IN+ 0:00,00 sh -c grep -l -r "^lib/libssl.so." "/var/db/pkg" |
while read contents; do sslprefix=`grep "[EMAIL PROTECTED] " "${contents}" |
/usr/bin/head -n 1`; if test "${sslprefix}" = "@cwd /usr/local" ; then echo
"${contents}"; break; fi; done
So I looked through some Mk stuff, and tryed to optimize it. Since I do not
know any magic of bsd.*.mk, I did just a simple test. And with the below shown
patch the time is only 1500 s, while with the original version the time is more
than 15000 s. I guess the time depens very much on number of installed ports,
I have about 1300.
The resulting INDEX* files are identical.
I should confess I do not understand how my patch works. I expected to see a
file /usr/ports/.openssl_installed or /tmp/index_something/.openssl_installed
or similar, but could not see it... But I hope this patch will inspire you
to do something really working.
