index worker 2.3.7 undefined symbol errors

Suddenly I am getting undefined symbol errors having updated to 2.3.7.

Jul 18 01:02:49 localhost dovecot: indexer-worker: Error: User <someone> 
lookup failed: Couldn't load required plugin 
/usr/lib/dovecot/modules/lib95_imap_sieve_plugin.so: dlopen() failed: 
/usr/lib/dovecot/modules/lib95_imap_sieve_plugin.so: undefined symbol: 
command_hook_register

(I think I fixed this one by a config change)

But I am left with this:

index worker 2.3.7 undefined symbol errors (more info)

Some supplemental information:

This is happening on every email delivered into Dovecot via LMTP. The 
curious things are that the message is a) successfully delivered and b) 
sieved into the correct directory.

Another observation is that:

mail_deliver_ctx_get_log_var_expand_table

is defined globally in core/src/lib-lda/mail-deliver.c (and used there) 
but the ONLY external call in the entire dovecot tree is from 
pigeonhole/src/plugins/lda-sieve/lda-sieve-log.c.

I am not using lda but it seems to be part of core. So, as I am only 
using lmtp, why is pigeonhole using lda-sieve at all?

Can I work around the error message by some config magic (as I did by 
calling the correct plugin for imap_sieve) or is this an actual bug? 
Could this be fixed simply by including mail-deliver.h in lda-sieve-log.c?

It's part of lib-lda, which is also used by lmtp.

I think you're not linking lmtp binary correctly somehow. That symbol should
be part of it:

% nm /usr/libexec/dovecot/lmtp | grep mail_deliver_ctx_get_log_var_expand_table
0000000000061960 T mail_deliver_ctx_get_log_var_expand_table

Oh.. it's logged by indexer-worker.

You can't load sieve globally. It needs to be inside protocol lmtp {}

That has fixed it, thank you.

It's not obvious from the documentation which are global plugins and 
which are protocol based ones. Would it be possible to put some words on 
plugin pages to indicate which is what?

Thanks for the help
