Migration 2.3 -> 2.4 + wormhole without patched version #2

catap commented 2025年10月25日 12:49:51 +02:00

Hi,

I think that it is wise idea to explain the way to migrate from dovecot-2.3 to dovecot-2.4 + wormhole when use hasn't got will or means to use patched version of dovecot.

As far as I understand it is achivable via downtime by shutdown all nodes, upgrade it with changes and config... and just start them up.

Am I wrong?

At anycase, I think that this approach should be documented as an alternative from patched hack.

I think so. But as I have not yet tested this, I did not mention it in the documentation already. I will check that soon and update the documentation accordingly. My primary focus was to document a migration path without downtime.

Thanks.

I'm thinking here from view of someone who wouldlike to move from dovecot-2.3 to dovecot-2.4 + wormhole as part of upgrade via distributive packages.

So, here no way to use patched dovecot, and upgrade with downtime seems the only way.

Or?

Well, that depends. On Debian you can rather easy recompile a package with some patch included and install the resulting packages. The source package of current Dovecot CE for Debian 12 Bookworm can be found here: https://repo.dovecot.org/ce-2.4-latest/debian/bookworm/pool/main/dovecot_2.4.1-4+debian12.dsc

dget https://repo.dovecot.org/ce-2.4-latest/debian/bookworm/pool/main/dovecot_2.4.1-4+debian12.dsc
cd dovecot-2.4.1
# patch it
patch -p1 < /path/to/wormhole/patches/dovecot-doveadm-dsync+exit_code-hooks_2025年10月12日.diff
# commit the patch to the debian patch list
dpkg-source --commit # will ask for the name of your patch
# create a new entry in debian/changelog
dch -l+local "Recompiled version with dsync_hooks patch for wormhole"
# build it
dpkg-buildpackage -us -uc
# .deb files will be created in ../

I have no idea how you can do something like that on other platforms as I am only using Debian. Ubuntu should work very similar.
(I'm happy to here how other do this on other platforms!)
At the end of the migration, I will recompile wormhole against the CE version of Dovecot and install and use those packages.

I see this way but it is much more complicated that apt install XXX :)

And I almsot sure that it isn't easy to sell dovecot-with-wormhole as dedicated package for migration without asking user to build packages.
