Message-ID: <159546998738.232977.10166967333633103899.reportbug@afu.lan>

Package: notmuch-mutt
Version: 0.30-1
Severity: important
Tags: upstream

Dear Maintainer,

After recently updating from stable to testing, notmuch-mutt search
and thread commands stopped including results from my "Sent Items"
maildir folder.  There are broken links in the results folder, and
symlink error messages in the terminal window after exiting mutt.

I tracked this down to upstream commit
<https://git.notmuchmail.org/git?p=notmuch;a=commitdiff;h=1fcf068e331b9b79e14f79c8b126711fc3d72cbb>
but unfortunately my shell-fu is not good enough to understand exactly
why the new version isn't working.

If I manually swap revert the diff then my Sent Items results start
working again.  So somehow the backslash-escaping works for xargs but
not for the shell while/read loop.

Here's the part of the commit above causing the breakage.

Heya, thanks for the heads up. I don't think I was involved in that
specific commit though, so I'm shamelessly punting to the author (added
to Cc:) :-)

(FWIW, I don't see either at first sight why it would break anything...)

Cheers

This could work, cannot test (compiles OK w/ perl -c when I outcommented
packages I don't have.

I'm not subscribed to the mailing list, so my reply there will probably 
bounce.

A quick test of your patch seemed to work for me.

Thank you!

I have the impression that Tomi's patch is a more thorough solution to
the same problem (although I didn't test it).

  https://nmbug.notmuchmail.org/nmweb/search/id%3A20200727193833.4654-1-tomi.ollila%40iki.fi

I would appreciate it if one of you could confirm or deny

I completely agree. I think rewriting the process in Perl instead of 
shelling out is the better way to go.
