Package Modification

Introduction

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

• CVS SME Server which holds the core packages of the SME Server
• CVS SME Contribs which holds the contribs packages

This page is to help you make changes to the contribs packages stored on sourceforge.

	Note:
	For now changes to the base are still made using mezzanine.

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

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

yum install --enablerepo=smedev 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.

• Copy your local public SSH key to SourceForge https://sourceforge.net/account/editsshkeys.php

• 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 src.rpm

Email admin@contribs.org with the location of your rpm, it will be imported into the build system for you.

Import cvs

This is just cvs information, not source code.

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 

(for now changes to smeserver are still made with the mezzanine method, and updated manually by devs)

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 them. Binary files are stored in a look-aside cache on shads box. CVS isn't great on binary files.

Mezzanine, (mzsfget, mzclean, mzprep, mzpatch, mzbuild, mzput) have all be replaced with a new method.

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 [optional]
make clean [optional]
make prep

Then switch to the tree and make modification.

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. (really empty = 0kb, some file manager don't!)

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.)

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

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 'msg'

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)"

Then tag all files as belonging to a particular build version

make tag

Then submit the request to the build server which will checkout the recently tagged version and build it in a chroot (mock) env.

make build

Key things are to 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 successfull build. Only you will get an email on failed build.

CVS cheat sheet Package_Modification/More cvs commands

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 succesfully 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 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 + ...
