Developer Test Environment¶
This assumes you have already succeeded in getting your development environment up and running, and that you’ve successfully got your basic server running and you’ve made some changes and you want to test them to work out what’s going right... or wrong.
Cassandane is a Perl-based integration test suite for Cyrus.
Why “Cassandane”? Wikipedia indicates that Cassandane was the name of the consort of King Cyrus the Great of Persia, founder of the Achaemenid Persian Empire. So that’s kinda cool.
Install and configure Cassandane¶
Clone the Cassandane repository (you can get the URL from the Diffusion app within Phabricator)
- If you are a member of IMAP Committers, use:
git clone ssh://email@example.com/diffusion/C/cassandane.git
- If you aren’t (yet), use
git clone https://git.cyrus.foundation/diffusion/C/cassandane.git
- If you are a member of IMAP Committers, use:
- Install dependencies
sudo apt-get install libtest-unit-perl libconfig-inifiles-perl \ libdatetime-perl libbsd-resource-perl libxml-generator-perl \ libencode-imaputf7-perl libio-stringy-perl libnews-nntpclient-perl \ libfile-chdir-perl libnet-server-perl libunix-syslog-perl \ libdata-uuid-perl libjson-xs-perl libdata-ical-perl libjson-perl \ libdatetime-format-ical-perl libtext-levenshteinxs-perl \ libmime-types-perl libdatetime-format-iso8601-perl libcal-dav-perl \ libclone-perl
There are a number of Perl modules required that aren’t already packages in the standard repository. A few aren’t in CPAN yet and should be installed from github.
git clone https://github.com/brong/Net-DAVTalk/ cd Net-DAVTalk perl Makefile.PL make sudo make install cd .. git clone https://github.com/brong/Net-CardDAVTalk/ cd Net-CardDAVTalk perl Makefile.PL make sudo make install cd .. git clone https://github.com/brong/Net-CalDAVTalk/ cd Net-CalDAVTalk perl Makefile.PL make sudo make install cd .. git clone https://github.com/brong/Mail-JMAPTalk/ cd Mail-JMAPTalk perl Makefile.PL make sudo make install cd ..
The quickest option for the rest is installing via CPAN, but you could build packages using dh-make-perl if that is preferred.
sudo cpan -i Tie::DataUUID sudo cpan -i XML::Spice sudo cpan -i XML::Fast sudo cpan -i Data::ICal::TimeZone sudo cpan -i Text::VCardFast sudo cpan -i Mail::IMAPTalk sudo cpan -i List::Pairwise sudo cpan -i Convert::Base64
- Install Cassandane
cd /path/to/cassandane make
cassandane.inito set up your cassandane environment.
Assuming you configure cyrus with
--prefix=/usr/cyrus(as above), then the defaults are mostly fine
[valgrind]if you’re using it.
- Add an
- For the moment, it may be necessary to suppress the binary tests as they are buggy upstream still.
- Add an
[imaptest] basedir=/path/to/imaptest/imaptest suppress=append-binary urlauth-binary fetch-binary-mime fetch-binary-mime-qp
- Create a
cyrususer and matching group and also add
sudo adduser --system --group cyrus sudo adduser cyrus mail
Give your user account access to sudo as
- add a line like:
username ALL = (cyrus) NOPASSWD: ALL, where “username” is your own username
destdirdirectory, as the
sudo -u cyrus mkdir /var/tmp/cass
IMAPTest is a testing suite which uses libraries from the Dovecot installation.
Fetch and compile Dovecot.
- Get the latest nightly snapshot from http://dovecot.org/nightly/dovecot-latest.tar.gz
./configure && make(No need for make install)
Fetch and compile IMAPTest
- Download http://dovecot.org/nightly/imaptest/imaptest-latest.tar.gz
./configure --with-dovecot=../dovecot-2.2 && make(No need for make install)
--with-dovecot=<path>parameter is used to specify path to Dovecot v2.2 sources’ root directory.
Rebuild Cyrus for Testing¶
Prepare to rebuild by making the source tree shiny and clean as if you’ve done a brand new checkout. Leave no old artifacts lying around!
cd /path/to/cyrus-imapd make clean git clean -f -x -d autoreconf -v -i
Apply caution! The
git clean removes anything that’s a build product, but also anything it doesn’t know about: which may include your new source files you haven’t added yet.
Set the compile flags for testing and debugging. It may be of use to also add
--std=gnu99 here. That does TONS of warnings, and
-g enables debug mode.
CFLAGS="-g -fPIC -W -Wall -Wextra -Werror"
Configure the environment.
./configure --prefix=/usr/cyrus --with-cyrus-prefix=/usr/cyrus \ --enable-autocreate --enable-http --enable-unit-tests \ --enable-replication --enable-nntp --enable-murder \ --enable-idled --enable-xapian --enable-calalarmd \ --enable-apple-push-service make lex-fix # you need this if compile fails with errors from sieve/sieve.c
And finally, make it.
If you’re testing across versions, the binsymlinks is necessary as older Cyrus doesn’t have the binaries in the new locations. This uses the default install path of
/usr/cyrus/. It can be useful to also have
/usr/cyrus24, etc, if you’re testing with older versions as well.
make -j16 && make -j16 check sudo make install sudo make install-binsymlinks sudo cp tools/mkimap /usr/cyrus/bin/mkimap'
Running the tests¶
cyrus, run the tests.
cd /path/to/cassandane sudo -u cyrus ./testrunner.pl -f pretty -j 8
Tips and Tricks¶
Read the script to see other options. If you’re having problems, add more
-v options to the testrunner to get more info out.
Looking for memory leaks? Run with –valgrind to use valgrind (if it’s installed). It is slower, which is why it doesn’t need to be always used.
Running with -v -v is very noisy, but gives a lot more data. For example: all IMAP telemetry.
Also helpful to run
sudo tail -f /var/log/syslog, and examine /var/tmp/cass as root to examine log files and disk structures for failed tests.
