named complains about lack of lmdb_mapsize


Beginning with bind-9.11.2-i586-1 I've gotten this message on boot:

Quote:
named[1094]: ./config.c: option 'lmdb-mapsize' was not enabled at compile time (ignored)
Is this a mistake I've made or a problem with the package? I built the package with the source, but I lack LMDB so I can't configure LMDB into it.

Hi,

Since you've built named from sources, you can recompile it adding the "--without-lmdb" option in ./configure, so it stops complaining.

No, I can't. I can't build it with lmdb in the first place. You misunderstood: I've been using the bind package until I noticed this message in /var/log/syslog. In an attempt to figure out what's happening I built my own, and it still results in the same message, so the problem isn't Slackware's package. I reported it in case Slackware's builders wanted to do anything about it. I don't think it impairs named's performance.

Apparently it does. Well, at least when you remove/modify zones.
From bind 9.11 release notes:
Quote:
When BIND is built with the lmdb library (Lightning Memory-Mapped Database), named will store the configuration information for zones that are added via rndc addzone in a database, rather than in a flat NZF file. This dramatically improves performance for rndc delzone and rndc modzone: deleting or changing the contents of a database is much faster than rewriting a text file.

I meant that named works for my purposes, which are undemanding. I think that everyone who knows what lmdb is installs it if s/he so desires. I reported my experience because innocently running named results in a warning in the log files, that, perhaps, somebody may want this not to happen: decreasing noise in log files is a benefit. By building it myself I can see that bind's authors started the behavior.

What's a Hungarian doing in Greece?
