[ANNOUNCE] autofs 4.1.4 beta2 release

[ANNOUNCE] autofs 4.1.4 beta2 release

[raven]

Hi all,

Here is autofs 4.1.4 beta2.

There haven't been many changes since beta1.

For more information look at the CHANGELOG in the distribution.

There are still a few problems that I'm aware of such as:

- the init script for Debian and Gentoo works better but still
    ins't handling the reload option completely.

- the bug with the selection of the default map type when using
    submounts still hasn't been resolved.

So let me know when you find more and I'll fix`em as quick as I can!

The distribution can be found at the usual place at:

http://www.kernel.org/pub/linux/daemons/autofs/v4

in the tars

autofs-4.1.4_beta2.tar.[gz|bz2]

also there is a tarball called:

autofs-4.1.4-beta2-deb.tar.[gz|bz2]

that can be used to build binary debs (see below).

It is possible to build packages for testing from the distribution. 
I'm not the maintainer of any of these distribution packages so please be 
aware that this is for convenience and testing.

To build an rpm package use:

rpmbuild -tb autofs-4.1.4_beta2.tar.gz

and the binary rpms will end up in the usual location.

To merge the package into Gentoo use:

tar zxf autofs-4.1.4_beta2.tar.gz
cd autofs-4.1.4_beta2/gentoo
export PORTDIR_OVERLAY=`pwd`
ebuild net-fs/autofs/autofs-4.1.4_beta2.ebuild digest
ebuild net-fs/autofs/autofs-4.1.4_beta2.ebuild clean install
ebuild net-fs/autofs/autofs-4.1.4_beta2.ebuild qmerge
unset PORTDIR_OVERLAY

To build binary debs for Debian download the tar refered to above and:

tar zxvf autofs-4.1.4-beta2-deb.tar.gz
dpkg-source -x autofs_4.1.4-beta2-1.dsc
cd autofs-4.1.4-beta2
dpkg-buildpackage -b

and the binary debs will be placed in the directory the tar was unpacked.

Hopefuly this will help with the testing

Ian

Thanks! :-)

I've gone through all the Debian patches again, and this needs looking into:

- 000_autofs_4.1.3_sock-leak-fix is missing.
- 035_program_mount_repeated_last_character_of_map_output is in there, but
  there looks like there's an identical situation further down. Could you
  investigate? (I'm not really sure if it is an error or not, to be honest, I
  just want it checked. :-) )
- 051_maps_without_trailing_newline.diff is not in, it seems; did you forget
  it or just find a cleaner way?
- The check for /proc/modules does not seem to have went in (see
  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=292762).

Apart from that, looks like everything went in; I'm building a new version
now and will upload after I get your feedback on the points above.

I just found another bug; on upgrades, autofs attempts to restart itself,
which invokes "debian stop"; this invokes something like

  start-stop-daemon --stop --quiet --retry USR2/$DAEMON_EXIT_WAIT --pidfile $file --exec /usr/sbin/automount

The problem here is that the pid does not really run /usr/sbin/automount
anymore; or more correctly, /proc/<pid>/exe does not point to the current
/usr/sbin/automount, it points to the _old_ /usr/sbin/automount, and that
version was just removed as part of the upgrade.  Thus, the stop fails, and the
entire upgrade fails.

Any good ideas? Stripping the --exec would be the easiest solution, but
perhaps also the ugliest...

OK, I found the bug; autofs was not stopped on prerm (this was disabled to
"fix" another bug). I've reverted the changes and made some workarounds; they
are not relevant for autofs upstream, but will be part of the next Debian
package.

I'll have to change this again, unfortunately; during testing I found a
machine which had been upgraded from 4.1.3-8 to 4.1.3-9 without reboot, and
thus "/etc/init.d/autofs stop" (which I tried to do in my preinst) was
broken.

I'll have to add a debconf notice telling the admin this and then just let
it break if it breaks; it's the only reasonably sane solution I can see.

I've just implemented this and uploaded autofs_4.1.3+4.1.4beta2-1 to Debian
unstable.

We solved this problem a different way.  If we pass RPC_ANYSOCK to the
portmapper, it will use a reserved port by default for communications.  To
keep it from doing that, we create the socket ourselves.  We then do this:

                clnt_control(client, CLSET_FD_CLOSE, NULL);

Which tells the rpc layer to close the socket for us when we destroy the
client.  As such, there is no socket leak.

Thanks,

Jeff

Yep. The patch was a bit out of date.

Thanks Jeff.

Actually, I fired too quickly on this one.  stderr is used for the error
reporting, so we shouldn't mark the state as done until we've read
everything from stdout.

http://home.samfundet.no/~sesse/052_292762_dont_lsmod_on_monolithic_kernels
-- as you can see, it checks that /proc/modules exists (which it only does on
kernels with module support) before calling lsmod. Of course, if /proc isn't
mounted, this breaks, but if /proc isn't mounted something is quite broken
anyhow...
