Cuirass is a continuous integration tool using GNU Guix.
|
|
|
|
* Requirements
|
|
|
|
Cuirass currently depends on the following packages:
|
|
|
|
- GNU Guile 3.0.x or 2.2.x
|
|
- GNU Guix (and all its development dependencies)
|
|
- GNU Make
|
|
- Guile-JSON 3.x
|
|
- Guile-Avahi
|
|
- Guile-Squee
|
|
- Guile-Git
|
|
- Guile-zlib
|
|
- Guile-Mastodon
|
|
- Guile-Simple-ZMQ
|
|
- Ephemeral PostgreSQL (for the tests)
|
|
- Mailutils
|
|
- Fibers
|
|
|
|
A convenient way to install those dependencies is to install Guix and execute
|
|
the following command:
|
|
|
|
#+BEGIN_EXAMPLE
|
|
guix environment cuirass
|
|
#+END_EXAMPLE
|
|
|
|
This will build and enter an environment which provides all the necessary
|
|
dependencies.
|
|
|
|
* Build Instructions
|
|
|
|
When all the dependencies are available on you system, in order to build
|
|
Cuirass, you can proceed with the usual:
|
|
|
|
#+BEGIN_EXAMPLE
|
|
./bootstrap && ./configure && make
|
|
#+END_EXAMPLE
|
|
|
|
* Database connection
|
|
|
|
Cuirass uses PostgreSQL to store information about jobs, past build results
|
|
and to coordinate the execution of jobs. The database connection string must
|
|
be passed to Cuirass using the =database= argument, under the keyword/value
|
|
format described [[https://www.postgresql.org/docs/10/libpq-connect.html#LIBPQ-CONNSTRING][here]]. The PostgreSQL database must be created beforehand.
|
|
|
|
By default, this command:
|
|
|
|
#+BEGIN_EXAMPLE
|
|
./pre-inst-env cuirass register
|
|
#+END_EXAMPLE
|
|
|
|
will connect using the Unix socket at =/var/run/postgresql= to the =cuirass=
|
|
database and is equivalent to:
|
|
|
|
#+BEGIN_EXAMPLE
|
|
./pre-inst-env cuirass register --database="dbname=cuirass host=/var/run/postgresql"
|
|
#+END_EXAMPLE
|
|
|
|
To use a TCP connection, one can use:
|
|
|
|
#+BEGIN_EXAMPLE
|
|
./pre-inst-env cuirass register --database="host=127.0.0.1"
|
|
#+END_EXAMPLE
|
|
|
|
* Run tests
|
|
|
|
Cuirass tests also require an access to a PostgreSQL database, provided by the
|
|
Ephemeral PostgreSQL package. The =pg_tmp= script needs to be part of the
|
|
path before running the usual:
|
|
|
|
#+BEGIN_EXAMPLE
|
|
make check
|
|
#+END_EXAMPLE
|
|
|
|
* Example
|
|
|
|
A quick way to manually test Cuirass is to execute:
|
|
|
|
#+BEGIN_EXAMPLE
|
|
./pre-inst-env cuirass register --specifications=examples/hello.scm
|
|
#+END_EXAMPLE
|
|
|
|
This will read the file "examples/hello.scm" which contains a list of
|
|
specifications and add them to the =cuirass= database. It will then build the
|
|
=hello= package on top of the default Guix channel.
|
|
|
|
Cuirass then loops evaluating/building the specs. The database keeps track
|
|
of the specifications in order to allow users to accumulate specifications.
|
|
To resume the evaluation/build process you can execute the same command
|
|
without the '--specifications' option:
|
|
|
|
#+BEGIN_EXAMPLE
|
|
./pre-inst-env cuirass register
|
|
#+END_EXAMPLE
|
|
|
|
To start the web interface run:
|
|
|
|
#+BEGIN_EXAMPLE
|
|
./pre-inst-env cuirass web
|
|
#+END_EXAMPLE
|
|
|
|
* Contributing
|
|
|
|
See the manual for useful hacking informations, by running
|
|
|
|
#+BEGIN_EXAMPLE
|
|
info -f doc/cuirass.info "Contributing"
|
|
#+END_EXAMPLE
|
|
|
|
You can authenticate the code in this repository by running:
|
|
|
|
#+begin_example
|
|
guix git authenticate \
|
|
c75620777c33273fcd14261660288ec1b2dc8123 \
|
|
3CE464558A84FDC69DB40CFB090B11993D9AEBB5
|
|
#+end_example
|
|
|
|
The command silently exits with zero on success, and errors out
|
|
otherwise. We recommend invoking it from =.git/hooks/pre-push=.
