segfaults with cyrus-imapd 3.0.9 on latest arch linux

[Patrick Goetz]

Hi Andreas -

Jakob has already updated the AUR package, which appears to have 
resolved this issue.  The related upstream bug is #2629.

Regarding the dependencies in the cyrus-imapd PKGBUILD.  I recommend 
starting with Jakob's PKGBUILD and just stripping out the stuff you 
don't need.  I've spent so much time looking at it at this point, if you 
tell me what you don't want, I can probably post a PKGBUILD that works 
for your requirements.

In any case, please try cyrus-imapd 3.0.9-2 and let me know if this 
resolves the issue for you, too.

Here is an explanation (provided by the AUR package maintainer) of the 
purpose of the various dependencies he's included (also the ones listed 
as requirements which he did not include).  We had pre-agreed that there 
is no harm in compiling in all the authentication hooks and 
CalDAV/CalCard dependencies.  Without the authentication hooks, the 
package isn't really general purpose.

- gperf seems to be useful for development only (maintainer mode)
- libbsd is only required for krb5afspts which is disabled (because IIRC 
it looks for static libraries which Arch doesn’t package)
- ICU: This seems to be genuinely missing, though as you noticed it is 
already required indirectly. It is probably still a good idea to make 
that dependency explicit. But since it’s a relatively minor problem I’ll 
wait to see if anything else comes up in our conversation so I can 
“bundle” the changes.
- clamav is in fact already in optdepends, however in order to build 
against it it needs to be in makedepends as well
- xapian-core provides efficient indexed search, which I’d argue is 
quite a useful feature to have in a mail server. It is linked into 
libcyrus_imap.so though, which is in turn linked into imapd (unlike 
clamav), therefore it is a hard dependency.
- libcap allows Cyrus’s services to restrict their own capabilities(7) 
for enhanced security
- libnghttp2 and brotli add support for HTTP/2 and Brotli compression of 
HTTP responses, respectively; which is relevant to CalDAV, CardDAV and 
other HTTP services (including JMAP in future versions)
- shapelib allows Cyrus’s Time Zone Distribution Service[2] to associate 
time zones with geographical locations
- python-sphinx, perl-pod-pom-view-restructured: required for generation 
of some manpages (which are included in the regular package, not the 
-docs one. I’d argue that manpages are actually useful to have around). 
These are only needed at buildtime and need not be present on the actual 
server system.
