Simple Package Modification (view source)
Revision as of 06:17, 18 November 2017
, 06:17, 18 November 2017Update CVS server details
{{Level|Developer}}
The simplest package modification is for someone to access the code via anonymous CVS and produce a patch to put into Bugzilla.
The simplest package modification is for someone to access the code via anonymous CVS and produce a patch to put into Bugzilla.
This can be done on SME 8 by installing only cvs as follows.
This can be done on SME 8 by installing only cvs as follows.
== Setting up your build server ==
This How-to is based on SME8, and that you have your development SME8 server fully updated and up and running. This can be a dedicated machine or a virtual machine.
==== Install CVS ====
SME Server uses CVS for maintaining code and packages. By default, CVS is not installed on SME8 (not required for normal SME Server operation). To install CVS on SME8 issue the following command as root user.
yum install cvs
Create a new user, eg builder
==== Create a new 'builder' user ====
We will create a new user account that we use for our building purposes. The new user account can be created, as usual, through the server-manager, In this How-To we will have named our new user account 'builder'
useradd builder
passwd builder
==== Grant shell access ====
The 'builder' account needs to be able to login and have shell access. For this you will need to grant permissions. Type the following commands from the root account:
chsh -s /bin/bash builder
db accounts setprop builder Shell /bin/bash
After issuing the above commands, the user 'builder' should be able to login on the console. Please login as user 'builder', for the the rest of the instructions assume you are loged in as user 'builder'
==== Create a development directory ====
The user 'builder needs a dedicated development directory. In this How-To we will use ~/home/smeserver. To create the directory ~/home/smeserver please issue the following command as user 'builder':
mkdir ~/smeserver
cd ~/smeserver
To add the smecontribs cvs:
mkdir ~/smecontribs
cd ~/smecontribs
This is all what is required to setup your server to be able to start working on patches and packages.
== Retrieve code ==
==== Getting the source code ====
In this How-To we want to work on the package 'e-smith-base'. We first need to download (with CVS this is called retrieving) the code for 'e-smith-base' from the SME Server CVS repository at koozali.org, we can also retrieve the CVS for the smecontribs tree. For this issue the following commands:
cd ~/smeserver
cvs -z3 -d:pserver:anonymous@shell.koozali.org:/cvs/smeserver checkout -P e-smith-base
For the 'smeserver-base' base from the contribs tree.
cd ~/smecontribs
cvs -z3 -d:pserver:anonymous@shell.koozali.org:/cvs/smecontribs checkout -P smeserver-base
Next to a selective retrieve as per above, you can also retrieve the whole CVS tree.
cd ~/smeserver
cvs -z3 -d:pserver:anonymous@shell.koozali.org:/cvs/smeserver co -P rpms
cd ~/home/smeserver
For the SME contribs tree.
cd ~/smecontribs
cvs -z3 -d:pserver:anonymous@shell.koozali.org:/cvs/smecontribs co -P rpms
If you want to update/refresh the whole CVS tree smeserver or smecontribs, run the following from the rpms directory, or any lower directory with a CVS dir , issue
cvs update -dPA
To work on the e-smith-base smeserver tree, change to the e-smith-base SME8 directory:
cd ~/smeserver/rpms/e-smith-base/sme8
* Alternatively retrieve the whole CVS tree
Then we have to prepare a tree. Issue the following commands:
cvs update -dPA
make clean
make prep
Please ignore if 'make clean' returns an error about a missing *.tgz package
Our patch will be a done with the 'diff' tool which compares the edited files against the original files. So we need to to save a copy of the original files:
cp -R e-smith-base-5.2.0 e-smith-base-5.2.0.old
== Make changes ==
==== Edit the source code ====
Now we can make the changes or edit the source code in e-smith-base-5.2.0.
For a simple test you can edit the SME8 'e-smith-base-5.2.0/root/sbin/e-smith/console' file and add something to the header.
cd ~/smeserver/rpms/e-smith-base/sme8
nano -w e-smith-base-5.2.0/root/sbin/e-smith/console

#----------------------------------------------------------------------
</pre>
Save the file
== Create a patch ==
When we have finished our editing of the source code (see above example), we can create a patch. (a file that contains the differences between the original file and the file we have been working on). To create the patch issue the following command:
cd ~/smeserver/rpms/e-smith-base/sme8
diff -urN e-smith-base-5.2.0.old e-smith-base-5.2.0 > e-smith-base-5.2.0-test.patch
make clean
==== Test the patch ====
To see if our changes work correctly as intended, we will make a local RPM build to test, and before building the RPM it is necessary to update the spec file to increase the release number and to ensure your patch is included in the build.
===== Update the spec file =====
First we will update the spec file. Spec files are text files that contain RPM directives and macro definitions, which are used to build an RPM package.
For our examle we will continue to use the e-smith-base-5.2.0
cd ~/smeserver/rpms/e-smith-base/sme8
Edit the file e-smith-base.spec
nano e-smith-base.spec
and change:
<pre>
#increase the release version at the beginning of the spec file
%define release 68
#add the patch to the existing patchlist section:
Patch2: e-smith-base-5.2.0-test.patch
#add the patch
Patch2: smeserver-foo-1.2-widget.patch
#update the changelog, include the bug number
#update the changelog section, including the release version and bug number
* Fri Jan 11 2008 John Smith <smith@foo.net> 1.2-15
* Wed Jan 23 2013 John Doe <jdoe@foo.net> 5.2.0-68.sme
- fixed foo to create bar [SME 3470]
- just a test to see if I can do this [SME: 7129]
#apply the patch in %setup
#add patch version to the %setup section
%patch2 -p1
%patch2 -p1
</pre>
</pre>
Save the file
To check the changes issue the following command which compares your updated spec file with the original one in CVS. This is an optional step, but helps catch errors in the spec file.
cvs diff e-smith-base.spec
cvs diff -u e-smith-base.spec
* Ensure that the changelog version really matches the RPM version.
* Check if the spec file correct, look at the changes
* There must be a bugzilla number in this format [SME: 7129]
* Is the date really correct? Both day and date.
* The version should follow after the email address
==== Build the test RPM ====
Build the rpm locally to test, (note, this deletes the working tree!<-- Please explain)
make local
A new RPM e-smith-base-5.2.0-68.el5.sme.x86_64.rpm will be created which you can test or explore to see if your changes are applied
Once the patch works, attach the patch to the bugzilla entry. That is all what it takes to create a patch.
You can also, optionally, attach the updated spec file.
This simple package modification ends here. The next section is intended for developers who have CVS commit and build access. The developers will also check your patches and apply them to the CVS tree for you.
== Committing the patch ==
==== If you have CVS commit access ====
CVS needs to be updated. To check what will be committed to CVS, issue the following command:
cvs update
* M modified, will be committed
* U file has been updated since you last checked it out
* A added, will be added on commit
* D deleted, will be deleted on commit
* ? egregious file not part of CVS record for this dir
* Ensure that the patch file has been added
cvs add e-smith-base-5.2.0-test.patch
* Ensure that your patch/files etc. are UNIX style and do not have DOS endings.
--- this simple package modification ends here ---
Once you are satisfied and want to submit the package to CVS 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'
for example
cvs commit -m '* Wed Jan 23 2013 John Doe <jdoe@foo.net> 5.2.0-68.sme
- just a test to see if I can do this [SME: 7129]'
cvs commit -m 'your descriptive commit message here'
==== If you have build access ====
Build it (from either the sme7 or sme8 dir):
