Introduction

SME Server code is stored in the CVS on http://www.sourceforge.net in two repositories:

Set up

Local environment

  • We now use cvs without needing mezzanine, check you have it installed
yum install cvs
  • Setup CVS to use ssh by creating /etc/profile.d/smebuild.sh with the following content
# Developer environment
# This gets symlinked into /etc/profile.d 

export CVS_RSH=ssh # tell CVS to use ssh

# DO NOT set CVSROOT

alias rm='rm -i'
alias cp='cp -i --preserve=timestamps'
alias mv='mv -i'

You have to logout an login again to the console for changes to take effects.

Access to build system

Check updates/status on the build server: http://buildsys.contribs.org


  Warning:
For contrib builders using the plague-client-0.5.0 you will need to downgrade to correct version, to fix this please do:
rpm -e plague-client plague-common
yum --enablerepo=smecontribs install plague-client


Ask admin@contribs.org for certificates, give the email address to use for notifications.

yum --enablerepo=smecontribs install plague-client

From now, do not use account "root" anymore. Use a dedicated dev account. Copy certificates and config file to ~/

.plague-client.cfg
.username.pem
.contribs-upload-ca.pem
.contribs-server-ca.pem

Don't forget to set the proper privileges on the file

chmod 600 .username.pem

Check it's working

Sourceforge access

  • SME Server code is stored in the CVS on http://SourceForge.net. To be able to work on your code in the SME Server CVS repository you need an account on SourceForge. With this account the development team can give you access to the CVS repository. More information can be found here:
B04: Registering a User Account
E04: CVS (Version Control for Source Code)
F02: SSH Key Generation and Usage
  • After you have created your SourceForge account you can ask the development team to give you developer access to smecontribs. Create a bug in the Bug Tracker as usual.
  • If local username is different to sf.net username edit ~/.ssh/config:
Host  smeserver.cvs.sourceforge.net
User  sfusername (without @shell.sf.net)
Host  smecontribs.cvs.sourceforge.net
User  sfusername (without @shell.sf.net)
  • Don't forget to set the proper privileges on the file
chmod 600 ~/.ssh/config

Usage

Import source

Email admin@contribs.org with the location of your rpm, it will be imported into the build system for you. Follow the same procedure when an upstrean release occurs, eg a new .tar.gz, Update your local cvs with:

cvs update -dPA

Import cvs

This is just cvs information and patches, not source tarball.

You can use ~/home/smeserver or whatever suits.

mkdir ~/smeserver
cd ~/smeserver
cvs -z3 -d:ext:smeserver.cvs.sourceforge.net:/cvsroot/smeserver co -P rpms 


mkdir ~/smecontribs
cd ~/smecontribs 
cvs -z3 -d:ext:smecontribs.cvs.sourceforge.net:/cvsroot/smecontribs co -P rpms 

To refresh run the following from the rpms directory, or any lower directory with a CVS dir

cvs update -dPA

Modify a package

Builders have rights to patch packages, tag, and build. If you need to upload new source tarballs or versions shad has to do that for now. Email Shad with the location of the source.

Create a bug at http://bugs.contribs.org against your contrib

Change to work directory

cd smecontribs/rpms/smeserver-foo/contribs7

To prepare a tree

cvs update -dPA 
make clean 
make prep
Make a patch

Then switch to the tree and make modification.

Method A

In the prepared dir copy a file you want to modify like so:

cp 28UserManagerProxyPass 28UserManagerProxyPass.{patchname}

Then modify the original file 28UserManagerProxyPass. To add new files touch the file.{patchname} so it is empty.

Once you have all the files you want patched copied and changed then you can build the patch (from the contribs7 dir) with:

make patch SUFFIX={patchname}

It will build and add the patch for you. It should be named "name-version-{patchname}.patch" (man gendiff. That is what the makefile uses to generate the diff file.)

Method B

Make a copy of the prepared directory, edit directly, then make a patch

cp smeserver-foo-1.0 smeserver-foo-1.0.old
diff -urN smeserver-foo-1.0.old smeserver-foo-1.0 > smeserver-foo-1.0-removeConfig.patch
Apply a patch

For example, check if a translation patch is available:

If patch size is 0 bytes there is nothing to do

Else go to the package folder in your tree and do :

wget http://translate.contribs.org/patches/contribs/{name}-locale-{date}.patch
cvs add {name}-locale-{date}.patch

Then you need to follow instructions in next part....

You may add yourself some translations , and wait for patch to be created (at about 2 AM GMT-6, or 6 PM Sydney)

Edit the spec
nano -w smeserver-foo.spec
#increase the release
%define release 15

#add the patch
Patch2: smeserver-foo-1.2-widget.patch

#update the changelog, include the bug number
* Fri Jan 11 2008 John Smith <smith@foo.net> 1.2-15
- fixed foo to create bar [SME 3470]

#apply the patch in %setup
%patch2 -p1
Commit

Build the rpm locally to test, (note, this deletes the working tree!)

make local       

Once you are satisfied and want to submit the package to the build server commit your changes. (Please use descriptive comments so that other developers are aware of what is happening. Comments will appear on the subject line of the commit email that get send to the other developers.)

cvs commit -m 'your descriptive commit message here'

You can automate the addition of the comments in the spec file with the command 'clog'.

  Note:
You will need to be in the sme7, sme8, or contribs7 directory for this to work


rm -f clog
cvs commit -m "$(make clog)"

CVS cheat sheet Package_Modification/More cvs commands

Build

Tag all files as belonging to a particular build version

make tag

Submit the request to the build server which will checkout the recently tagged version and build it

make build

Always do "make tag" before "make build"

Always ensure you are working with the latest version (cvs update -dPA)

You and updatesteam will get an email on successful build. Only you will get an email on failed build.

You can check the build system is working:

plague-client list uid  {task number}

Releasing a package

After the make build command the build system will try and build your package. After a successful build it will be put in the smetest repository. You should be notified of the result of the build by e-mail.

Once a package is build successfully you should verify your changes, ideally you would have a bug to verify for each modification. After verification of all relevant changes and bugs you can release the package like this:

  1. Login to shell.contribs.org like this: ssh username@shell.contribs.org
  2. Navigate to the teams directory: cd /teams
  3. The teams directory contains a few directories of which two are relevant, the first is called updates which will hold the SME Server packages, the other is called contribs and will hold build contribs. Suppose we would like to release our contrib we would proceed like this: cd contribs/7
  4. Now copy the relevant package from smetest to smecontribs, old versions are removed automatically cp smetest/package-name-version.rpm smecontribs/


  Note:
Within a period of two hours the package should be moved to the smecontribs repository and be available as soon as the mirrors synchronize.


Workflow

Once the server successfully builds it will automatically be pulled on the next repo update run (40 past the even hours MDT). The package will either be put into the smedev (new package) or smetest (exist in higher repo) After verification the package is manually moved from smedev/smetest to smecontribs (for contribs) or smeupdates-testing (for packages in base)

Mailing Lists

Subscribe yourself to the devinfo mailinglist. This is the place to discuss the development of the server and contribs. If you have other questions, not regarding development please use the forums.

Other lists exist to monitor bugs and the build system, UpdatesTeam + ...
