Fwd: [tor-relays] tcmalloc in FreeBSD
Hi, I posted this message in tor-relays, but it seems to me (and another people) that dev mail-list is better channel to use. Thanks! -------- Original Message -------- Hi all, From time to time my tor node (minibofh) stopped to work properly; since it's a tiny FreeBSD VPS, the root origin was some CPU over-consumption. I'm taking some actions to fix it (more swap, freeing CPU from another services... etc). The FreeBSD tor port offers to you the tcmalloc compilation option, so I had some fun reading this interesting paper: http://goog-perftools.sourceforge.net/doc/tcmalloc.html I recompiled the tor port but just using the tcmalloc option. Actually, now I got the google-perftool package and, obviously, the tcmalloc library: mb# pkg_info | grep google google-perftools-1.8.3 Fast, multi-threaded malloc() and nifty performance analysi mb# pkg_info -L google-perftools-1.8.3 | grep malloc.so /usr/local/lib/libtcmalloc.so /usr/local/lib/libtcmalloc.so.2 But, when I'm checking which libraries the tor binary is using, I get: mb# ldd /usr/local/bin/tor /usr/local/bin/tor: libz.so.5 => /lib/libz.so.5 (0x281aa000) libm.so.5 => /lib/libm.so.5 (0x281bc000) libevent-2.0.so.6 => /usr/local/lib/event2/libevent-2.0.so.6 (0x2844e000) libssl.so.7 => /usr/local/lib/libssl.so.7 (0x28489000) libcrypto.so.7 => /usr/local/lib/libcrypto.so.7 (0x284d7000) libthr.so.3 => /lib/libthr.so.3 (0x281df000) libc.so.7 => /lib/libc.so.7 (0x28090000) So... I understand that the tor binary is actually NOT using the new tcmalloc library. Am I wrong? PS. I adding a CC to tor FreeBSD port mantainer.
Hm. Tor itself doesn't have a tcmalloc compilation option, so whatever it's doing is something freebsd added. To debug this kind of thing, what I usually suggest is to rebuild and look carefully at which compiler and linker options are used in building Tor, and see if they include the appropriate options for tcmalloc. Good luck, -- Nick

Thanks for your answer Nick, but I don't get you: https://lists.torproject.org/pipermail/tor-commits/2008-February/008381.html It seems tor has a configure option to support tcmalloc since 2008; I guess I could be wrong (again) but I understand that if the configure script supports the tcmalloc option is because, is some sense, the compilation will use as well the mentioned libraries. So?

Oops; I'd forgotten about that. That's what I get for answering email on vacation without checking the code. I think my debugging advice still stands though:

What line does the build process use when linking Tor? yrs, -- Nick
What line does the build process use when linking Tor?
Hi again Nick, I have no idea, but I guess I could do the next: 1. Stop the tor service 2. deinstall the present port 3. Check the tcmalloc option is enabled 4. install the port and redirect all the output to a log file $ /usr/local/etc/rc.d/tor stop $ cd /usr/ports/security/tor $ make deinstall $ make showconfig $ make install >& /tmp/tor_freebsd_port.log and send to you the log. What do you think?

Sounds pretty involved! Is there really no way to recompile software from a freebsd port without uninstalling it? -- Nick

Remove (or move) the port's ‘work’ directory and run ‘make’. (You can't easily *install* an upgraded or recompiled FreeBSD port or package without removing the old one, though.) Robert Ransom

Nice. Maybe we're skipping something obvious, because I remember perfectly that google-perftools package was installed when I configure the port to use tcmalloc. Still, it seems not using it at all.

Have a look near the top of "config.log" (please don't send the whole file; it will be enormous) -- there should be a part that says what command line configure got.
I guess is /usr/ports/security/tor/work/tor-0.2.2.37/config.log Well, in here I see: This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake. It was created by configure, which was generated by GNU Autoconf 2.69. Invocation command line was $ ./configure --with-openssl-dir=/usr/local --disable-asciidoc --enable-linker-hardening --enable-gcc-hardening --enable-buf-freelists --disable-instrument-downloads --enable-threads --enable-transparent --prefix=/usr/local --mandir=/usr/local/man --infodir=/usr/local/info/ --build=i386-portbld-freebsd8.1 ## --------- ## ## Platform. ## ## --------- ## hostname = mb uname -m = i386 uname -r = 8.1-RELEASE uname -s = FreeBSD uname -v = FreeBSD 8.1-RELEASE #0: Mon Jul 19 02:55:53 UTC 2010 root@almeida.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC /usr/bin/uname -p = i386 /bin/uname -X = unknown /bin/arch = unknown /usr/bin/arch -k = unknown /usr/convex/getsysinfo = unknown /usr/bin/hostinfo = unknown /bin/machine = unknown /usr/bin/oslevel = unknown /bin/universe = unknown PATH: /sbin PATH: /bin PATH: /usr/sbin PATH: /usr/bin PATH: /usr/games PATH: /usr/local/sbin PATH: /usr/local/bin PATH: /root/bin So, actually I cannot see the tcmalloc is used by configure.

Yup. No --with-tcmalloc there. For whatever reason, the freebsd build process didn't pass --with-tcmalloc to configure. If the ports maintainer isn't being responsive, maybe some other freebsd people could have a look? If the build process is telling Tor the wrong stuff, then that is almost certainly something going wrong with the build process. -- Nick

I will try again to contact them.

FYI: http://lists.freebsd.org/pipermail/freebsd-ports/2012-August/077433.html Let see if someone is taking care of this one.
Well, finally it seems a Tor configure.in bug/problem: http://lists.freebsd.org/pipermail/freebsd-ports/2012-August/077440.html So.. I guess it has to be fixed by some tor dev then.

Very interesting. That first stanza is indeed wrongly placed. But when you move it, does it start working? And why does it seem that ./configure is not getting the --with-tcmalloc option at all? -- Nick

I tried a couple of things without success. So, what code should be placed in where?
And why does it seem that ./configure is not getting the --with-tcmalloc option at all?
No idea.
That's really strange. With a non-modified configure.in (which means that is containing this misplaced stanza), I did: # cd /usr/ports/security/tor/ # make deinstall # make clean # make install and... voilá: mb# ldd /usr/local/bin/tor /usr/local/bin/tor: libtcmalloc.so.2 => /usr/local/lib/libtcmalloc.so.2 (0x2844e000) libz.so.5 => /lib/libz.so.5 (0x281aa000) libm.so.5 => /lib/libm.so.5 (0x281bc000) libevent-2.0.so.6 => /usr/local/lib/event2/libevent-2.0.so.6 (0x284b6000) libssl.so.7 => /usr/local/lib/libssl.so.7 (0x284f1000) libcrypto.so.7 => /usr/local/lib/libcrypto.so.7 (0x2853f000) libthr.so.3 => /lib/libthr.so.3 (0x281df000) libc.so.7 => /lib/libc.so.7 (0x28090000) libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x286a1000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x281f4000) So it seems the 'make clean' did some magic. According to man ports(7): clean Remove the expanded source code. This recurses to dependencies unless NOCLEANDEPENDS is defined. Should I understand it was some 'expanded source code' which was breaking my local ports tree?
