Package: mairix
Version: 0.14-1
Severity: normal

Hello,

I'm having difficulties setting up mairix. This is my .mairixrc file:

base=/home/enrico/Maildir
maildir=...
mfolder=mairix
mformat=maildir
database=/home/enrico/.mairix_database

I now run mairix:

$ mairix -v -o ~/Maildir/.mairix-debtags debtags

open: No such file or directory

Strace says that it can't open /home/enrico/.mairix_database . I do it
and:

$ touch /home/enrico/.mairix_database
$ mairix -v -o ~/Maildir/.mairix-debtags debtags

The stack trace is not that helpful:

From the segv below, I imagine that it is an error for mairix to have

a zero-length database file. I don't think the stack trace is
important. What is important is that you should not create the
database yourself.

By the way, I uploaded a major new release of mairix yesterday. You
may want to try that version after you delete the ~/.mairix_database
file you created.

As for your configuration file, I don't know if it is correct or
not. I did find it unusual that you set your maildir to '...'. What is
that supposed to mean?

If you have questions about correctly setting you your configuration
file, you may want to directly email the upstream author.

Oh, I see. I was lead in doing that by the "open failed" message.
Now that I understand the situation, I really suggest that if mairix
doesn't find the database, instead of saying "open failed" it should
say "Please run mairix with no arguments to create the index." and, why
not, if isatty(1), also a "Do you want to generate the index now (it may
take a long while)? [Y/n]".

I've run "mairix" with no arguments and it generated the index for me.
Then I noticed that the manpage doesn't tell how to run mairix in index
mode, it just tells you that you can.

Also, the manpage doesn't document the -o switch.

It means "index all the mailboxes". It works, and it's a quite obvious
thing to do, although it's never mentioned in any of the examples and
it's not obvious to come up with that.

If you have questions about correctly setting you your configuration
file, you may want to directly email the upstream author.

Sure, thanks. This getting started with mairix has been quite a source
of suggestions for small improvements. I'll Cc upstream with this
message, then.

Another thing that I can't find out how to do is how to index all
folders BUT some. For example, I'd like to index all folders except
sent-mail and mairix-*, possibly without having to alter my folder
naming scheme or moving sent-mail and mairix search folders in another directory, or I get crazy finding them with mutt.


Ciao,

Enrico

Hi Enrico,

It's fair to say that there isn't really much checking of the database
file at all. It would be hard (and slow) to guard against all possible
forms of corruption. I took the view that if somebody messes with the
file and expects mairix to handle it, they get what comes to them.

In the case of a missing db file, it would certainly be better to have a
more helpful message, as you suggest.

Then I noticed that the manpage doesn't tell how to run mairix in index
mode, it just tells you that you can.

Also, the manpage doesn't document the -o switch.

The manpage is not kept up to date like the texi file. I used to rely
on other people sending in patches for the manpage. (I don't like
manpage format so I tend to avoid dealing with it.)

I guess the easiest thing to do is to add a statement to the top of the
manpage that it may be out of date compared to the texi file.

I'll see if I can add this to the manual as it's certainly a useful
trick.

folders BUT some. For example, I'd like to index all folders except sent-mail and mairix-*, possibly without having to alter my folder
naming scheme or moving sent-mail and mairix search folders in another directory, or I get crazy finding them with mutt.

Yes, I hoped to get around to adding this sometime. When I added the
globbing support to the folder specification stuff, I intended this kind
of thing to be possible sometime. I've never got round to working out
the details of what's really needed though.

Cheers
Richard
