Re: [FTS Xapian] Beta release

Can you send the log part that includes the "init" of the plugins (something similar as below) ?

WHich version of Xapian are you on ?

I tried to delete the message, but this does not help (crashes e.g. after message 2029 or 2044). Other folders with fewer messages were successfully indexed before.

Sorry, could not convince dovecot to create core dumps (read the docs, changed /proc/sys/kernel/core_pattern, added LimitCORE=unlimited/infinity, even created /etc/systemd/system/dovecot.service.d/coredump.conf to no avail). Custom Dovecot 2.3.4 on Debian Stretch.

Thanks, Paul

Now, when I type "make install", the lib is not pushed into dovecot folder, but somewhere in /usr/local/...

How to adjust this to have it arriving in the proper folder ?

Depends on your system. It mostly a matter of setting a proper --prefix directory for configure, but other paths are configurable as well. I usually check what the official distribution package for Dovecot is doing and use that as a basis.

For Debian I use the following configure command:

./configure --with-ldap=plugin --with-ssl=openssl --with-sql=plugin --with-lua=plugin --with-pgsql --with-mysql --with-sqlite
--with-gssapi=plugin --with-solr --with-ioloop=best --enable-maintainer-mode
--prefix=/usr --sysconfdir=/etc --libexecdir=/usr/lib --localstatedir=/var --mandir=/usr/share/man
--infodir=/usr/share/info --with-moduledir=/usr/lib/dovecot/modules --disable-rpath --disable-static

Stephan

Oh, right, a distribution tarball doesn't include some of the necessary files for your repository like autogen.sh and .gitignore. The attached tarball includes all those and is ready for git init. The previous tarball was made with make distcheck from this one.

Hi Joan,

Op 13/01/2019 om 19:03 schreef Aki Tuomi:

Yes, from compiling point of view it is done.

Unfortunately what is not done is all the other work involved, such as fixing all the inevitable bugs it has and maintaining it. We do not want, at this moment, take up maintaining and developing yet another FTS plugin as we have plenty of things to do already.

I invite you to setup your own repository and provide this plugin from there, being the maintainer of this plugin. We can add a link to your plugin on our FTS page so people can also find it.

There are other plugins like this, e.g. https://github.com/st3fan/dovecot-xaps-plugin

I turned the code you provided into a separate plugin package. The distribution tarball is attached.

Notable changes:

• Added example copyright headers and COPYING and AUTHORS files. You should modify those to your preference.
• Added README and INSTALL files (in markdown using Pandoc). Those need to be amended with details.
• Amended the plugin code to display a debug message with the plugin name and version upon plugin load.

I advise you to turn this into a git repository and continue from there.

I do not recommend releasing this plugin with the -fpermissive flag and the resulting warning as it is now. But I'm assuming this is still a work in progress, so that is OK.

Regards,

Stephan.

The only point here of this fts-xapian is to get rid of solr (because it is just a nightmare to setup) and squat (because it is considere obsolete).

I already sent the changed in configure.ac, makefile.am, etc.. in order to include it in the dovecot, and it compiles properly

The only remaining point is to push it in hte git (yes, everything is already done)

Hi

Please find attached the beta release of FTS Xapian, with the objective to replace fts_squat that is being deprecated.

Configuration is exactly the same as for fts_squat:

plugin {

plugin = fts fts_xapian (...) fts = xapian fts_autoindex = yes fts_enforced = yes fts_xapian = partial=2 full=20

This is installed on my production server (>120Gb of mailboxes), and I will observe it during the coming days.

I will definitely appreciate that this is added in the core git of docevot, in order to have a versionning of it, to remove squat and let basic users able to avoid Solr alternative as much as possible.

Thanks

Hi!

I still recommend you setup a, say, github repository for your plugin. We are not able to currently include your work in dovecot core as it is more work than just pushing the code into the repo. Maybe it can be included in the future.

If you want, I can help you in setting up the required configuration scripts and such to make it possible to compile it as plugin.

Then anyone can download it and install it for their dovecot, even if dovecot itself has been installed from packages, and also makes it possible for package maintainers to consider including it in distributions.
