I have a build of net-snmp refreshed from CVS on 10/20. I also have a
build of net-snmp-5.2.1.2. I have configured with the same exact
options and built in the same way. The problem is the CVS exe is
gigantic, while the 5.2.1.2 exe is very small. I was wondering what
gives? It looks like both the .rodata and the .text segments are
gigantic for the CVS refreshed version.
here is a 'file' on both:
CVS Version:
snmpd: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux
2.2.5, dynamically linked (uses shared libs), not stripped
ls -l snmpd
-rwxr-xr-x 1 badger users 2722208 2005-10-25 11:48 snmpd
5.2.1.2 Version:
snmpd: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux
2.2.5, dynamically linked (uses shared libs), not stripped
ls -l snmpd
-rwxr-xr-x 1 badger users 45212 2005-10-25 11:55 snmpd
Here is the objdump -h of the CVS version - followed by the objdump -h
of the 5.2.1.2 version. Look in particular at the .rodata and .text
segments. Is there some gigantic array that is being created and
never used somewhere? The good news is that the memory used by the
running processes looks almost exactly the same. But snmpd going from
taking up 45K to 2.5Meg is not cool.
I know, I know - I should update to the latest CVS and/or only used
blessed versions - but I partly wanted to bring this up here in case
it wasn't seen yet so that it could be looked into before release. I
will, of course, help to track this down in any way I can. If it has
been fixed recently, then apologies for the noise.
