debugging nnmail-split-fancy

Platform: Gnus 5.4.56/GNU Emacs 19.34/SPARC Solaris 2.5

I tried switching to nnmail-split-fancy, yesterday, but I find the
debugging facilities, somewhat er... lacking...

Here are the last messages from the *Messages* buffer:
	Getting mail from the post office...
	Getting mail from po:sb...done
	Error in `nnmail-split-methods'; using `bogus' mail group
	Wrote /opt/home/sb/Mail/bogus/62
	Error in `nnmail-split-methods'; using `bogus' mail group
	Wrote /opt/home/sb/Mail/bogus/63
	Error in `nnmail-split-methods'; using `bogus' mail group
	Wrote /opt/home/sb/Mail/bogus/64
	Error in `nnmail-split-methods'; using `bogus' mail group
	Wrote /opt/home/sb/Mail/bogus/65
	nnml: Reading incoming mail...done

I'll keep on investigating, but as always, I appreciate pointers in
the right direction.

Thanx!

I've simplified it: removed the (& thing, and some bogus paranteses,
and now it works.

But a little more debugging info, would have been nice here.
Something for the TODO-list, perhaps...?

Just something that would point you to the approximate spot in the
splitting code, wherw Gnus got confused...

The fancy split routine doesn't really check the syntax used, so Gnus
doesn't really know what goes wrong.

Well, testing the splits with live mail is unwarrantedly risky -- "B q"
(gnus-summary-respool-query) on a message you've already got is a much
safer test since it doesn't actually *do* anything...

I'm not sure how "Debugging" the splits would actually work,
though... it might be possible to put some optional message calls in
the split handling routines, but they'd have to spew basically
everything ("rule %s didn't match %s" for each rule for each
message...)  In case it wasn't clear, the refile to "bogus" is what
happens if it *falls off the end*.

(: gnus-registry-split-fancy-with-parent)
(to "mac-users@.*acmecorp\\.com" "acmecorp.mac-users")
"acmecorp.mac-users"
(: nwalsh-incoming-group)
"archive.2019-02"

But the message wound up in acmecorp.sales. :-(

Run B t (gnus-summary-respool-trace) on the message.

Just a hunch, perhaps you want to check nnmail-mail-splitting-decodes

I have

(setq nnmail-mail-splitting-decodes t)

Debugging nnmail-split-fancy

Hello world,

I use nnmail-split-fancy to route incoming mail to any of a few dozen
(or more) folders. Very occasionally, and with no discernable pattern,
I find a message in the wrong folder. (I have no idea how often this
actually happens, but I only notice very occasionally.)

So, for example, I find a message in “acmecorp.sales” that’s clearly
part of a thread that I’ve been reading in “acmecorp.mac-users” (in
this case). I type “B q” and Gnus (v5.13 btw) says:

  This message would go to archive.2019-02, acmecorp.mac-users

Yeah. Except, it didn’t. It want to “acmecorp.sales”.

Any clue how to debug this?
