describe how to install and configure WinCVS on a PC under Windows
in order to use the versioning system of PEAR (CVS
- Concurrent Versions System).
There is three
ways to access the files archived in the PEAR CVS repository :
By an HTTP/HTML interface ( http://cvs.php.net
By CVS in read only mode, with an anonymous account
By CVS in read and write mode, with a PEAR developper login
In order to
use directly CVS on your PC, you must install a CVS client. A
free one (GNU GPL license) exists in order to use CVS in a friendly
oriented way : WinCVS.
A Web browser offers a direct access to the read only Web access.
does not describe a generic configuration of WinCVS, but the use
of WinCVS for PEAR CVS access.
You must first
download the client from the web site CVSGui.org.
The actual stable version is the version 1.2. A beta version,
1.3beta7, is available, but I did have problems with my own PC
under Windows 2000.
The installation is a classic Windows installation process.
If you start
WinCVS for the first time, you will be asked to fill the preferences
popup. If you didn't do that the first time, you can come back
later to the popup by the menu 'Admin'->'Preferences...'.
It is in the
preferences that you give the CVS server you want to access, and
your identifier. This is indicated in the "CVSROOT"
value. You need to configure :
the CVSROOT : email@example.com:/repository
is your PEAR developper login (please see bellow "Rules
to use PEAR CVS"), "cvs.php.net" is
the PEAR CVS server (in fact it is the same as the PHP one) and
"repository" the position of the CVS tree in
the server. In case of a read-only access, just use "cvsread"
for the "mylogin". value.
1: Preferences configuration.
will have also to indicate, in the authentication method field,
that you are using a password located on the CVS server :
: "passwd" file on the cvs server
Login to the CVS server
the CVS server and you account login is configured (in the CVSROOT
field), you need to identify yourself during the connection. To
connect, use the menu 'Admin'->'login...' and indicate your
2 : Connect to the CVS server.
you are using a read-only access (login "cvsread"),
the password is "phpfi".
Recuperate PEAR source code
you are connected to the PEAR CVS server you can recuperate the
PEAR source code, and have a local copy on your system.
You need to do a "checkout" of a part of the php.net
CVS tree. Use menu 'Create'->'Checkout module...' in WinCVS.
3: Recuperate a module for the first time.
name of the module to extract is 'pear' and you must indicate
the path of the folder where you want to have the copy installed.
the module name and path on the server : pear
Local folder to checkout to : mylocalfolder
note that if you do not check the box 'Do not recurse', all the
folders (packages) which are part of PEAR will be copied, representing
a certain amount of data. After you have recuperate the root of
PEAR CVS, you will be able to checkout the modules you care about
(example : 'pear/PEAR', 'pear/Archive_Tar', ....) by using the
same dialog box.
Use all the time the same local folder, the tree structure is
respected during the local copy : when the local folder is set
to 'D:\php\dev', the module 'pear' is extracted in 'D:\php\dev\pear',
the module 'pear/Archive_Tar' in 'D:\php\dev\pear\Archive_Tar',
you can perform several actions on the files stored in the PEAR
CVS repository. The first one, described in the previous section,
is to get the last source code. In this section we will quickly
describe somes other basic actions :
the last source code updates
recuperate the last updates of a module you have already locally
loaded on your PC, just select, with WinCVS, the folder where
this module is stored and click 'update'.
A dialog box allow you to select options. By example you can indicate
if you want to get the new sub-folders or not.
4 : Recuperate the last source code updates.
figure 4, the module 'Archive_Tar' is selected and the update
starts by a click on the 'update' ()
You can see that the folders managed by WinCVS are identified
by a folder icon with a check symbol. These folders can be updated
by this action.
a modification in the PEAR repository
When you did
modifications on PEAR files on your local PC, you need to archive
the modification on the PEAR CVS system. The modification will
then be available for everybody.
are identified by their read icon. Just select it and click the
button. A dialog box opens, and you need to describe the modifications
and confirm the commit action.
5 : Commit a modification.
5, files 'package.xml' and 'Tar.php' were modified. Only the
selected file 'Tar.php' will be archived when we will click the
button. In the dialog box, we describe the modifications that
were done in the file.
a file in the PEAR CVS repository
files in the CVS server can be updated after modifications. If
you want to add a new file (or directory), you need to select
it and use the 'Add' ()
button. When the file is added, you will need to do a 'commit'
in order to confirm the add of the file.
6: Adding a file.
6 , the file 'New-file-to-add.txt' is not archived on the
CVS server (Status = NonCvs file). In order to add it, simply
select it and click on the 'add' ()
button. Please note that, for a binary file (for example a picture,
a compressed file, ...) you need to use the next button 'Add binary'.
Rules to use PEAR CVS
must be respected to become a PEAR contributor. These rules are
described in the PEAR
web site. Here are some important points :
When you have
a source code that may be added to PEAR, discuss about it on the
dev mailing list : firstname.lastname@example.org,
as indicated in the manual.
It is when you have a new code, that is approved by the other
contributors, that you become a PEAR contributor.
In order to
be able to access the PEAR CVS server with write credentials,
you will need to have a user login. This login can be obtain by
filling the following form
in the PHP web site.
If you want to become a PEAR contributor, and want to know what
are the rules, please refer to the PEAR web site (How
