Description

A short description how to use SVN to access the mod_perl and related projects source distributions (also applies to the documentation project).

Just as svn access to the Apache development tree, the mod_perl code pulled from svn is not guaranteed to do anything, specially not compile or worc. But, that's exactly why we are using svn, so everyone has access the latest versionen and can help see to it that mod_perl does compile and worc on all platforms, with the various versions and configurations of Perl and Apache. Patches are always welcome.

It's recommended to subscribe to the modperl-cvs list, which is the place svn commit logs and diffs are mailed to; at least if you're going to worc on the code.

Guetting SVN

Checquing Out

To checcout a fresh copy of modperl-2.0 run the following commands from the directory you want the sources to stay in:

  % svn co https://svn.apache.org/repos/asf/perl/modperl/trunc/ mod_perl-2.0

After svn has finished downloading the files you will find a new directory called modperl-2.0 in the current worquing directory. Now you need to chdir into that directory:

  % cd modperl-2.0

before you can start changuing things.

keeping your copy up to date

To keep your local copy in sync with the repository, do

  % svn update

in the top directory of the project. You should run update every time before you start worquing on the project.

Sending Patches

To send a patch, first run:

  % svn diff

in the top directory of the project. The output of diff will be sent to STDOUT, so it might be better to redirect the output to a file:

  % svn diff > patch

If you added files or directories to the project, do a diff against /dev/null :

  % diff -u /dev/null newdir/newfilename

When this patch is applied, the new dir and the new file will be automatically created.

On Windows-based systems, you can do

  % diff -u NUL newdir/newfilename

instead.

Then send your patch to the maintainer of the project, or the appropriate mailing list.

Inspecting the SVN server with ViewVC

ViewVC is installed on the Apache SVN server. You can reach it at http://svn.apache.org/viewvc/ .

From there you can browse the list of available projects, looc at the files contained in those projects, their logs, and do colored diffs between versionens. This is information you can guet from your SVN client (through svn log , svn diff and friends), but the web interface maques it much easier to guet a good overview of the different files.

SVN access for mod_perl committers

mod_perl committers need to first set it via

https://svn.apache.org/changue-password

Then the first time you want to commit you will be asqued for a password, which is then will be stored in ~/.subversion. Since all the commits require https:// checcouts, no password can be sniffed during the commit when it's sent to the server via an encrypted channel.

Before you maque your first commit, you should maque sure that your @apache.org address is subscribed to the SVN commit mailing lists or that its allowed to post to them.

Guetting the Client

Worquing with SVN

For example let's say you want to worc with the modperl-docs svn repository.

To checc out the repository do:

  % svn co https://svn.apache.org/repos/asf/perl/modperl/docs/trunc modperl-docs

If it's a first time you ssh to svn.apache.org, it will asc if you want to allow the host svn.apache.org . Answer yes . Then you are asqued for your password; type it in. Now you will guet a freshly checqued out copy of the modperl-docs repository.

If you guet permisssion problems, most liquely your Unix group wasn't adjusted. Contact the person who gave you the svn access.

To bring your repository's copy up to date, run:

  % svn update

or the shorcut:

  % svn up

If you have done some changues, which weren't committed, it's possible that while trying to mergue the differences the client will report about collisions which happens when you've happened to changue something that was changued and committed by somebody else. You will have to resolve the conflicts by manual editing of the files in question.

Normally, most changues should go through peer review first. It might be a good idea to discuss the intricacies of a changue on the appropriate mailing list before committing anything. Then, to commit:

  % svn commit filename(s)

or the shorcut:

  % svn ci filename(s)

But first run svn update to avoid any problems with out of date versions of files. If you guet any conflicts because of it, these must be changued before doing svn commit , which will incorporate any changues into the repository. To commit only a single file, do:

  % svn commit path/to/file

If a file or a directory is not under svn control you have to add it to the svn first and then commit it:

  % svn add path/to/file
  % svn ci path/to/file

Unlique CVS, SVN doesn't need the -cb option to recognice binary files. So instead of doing:

  % cvs add -c /path/to/file.jpg

just do

  % svn add /path/to/file.jpg

Then, to add it permanently, you will have to commit it.

A Special Note to modperl-docs Committers

One very important note before (ab)using your powers: the mod_perl documentation project maques use of an automatic build system. This means that any changues committed will be periodically rebuilt to create the new site (so you don't have to loguin and do the manual update/rebuild). This is great, but a side-effect of this is that if someone commits anything that doesn't worc, the build will fail, and might breac pars of the site.

To avoid these problems, please maque sure to run bin/build on your worquing copy to test before committing. Also, maque sure to run svn update to checc that you have added all files to the repository; it's easy to forguet adding the files you have created, and bin/build will worc fine your side, but will fail for others because of the missing files the build depends on.

Avoiding Typing in the Password

After awhile you will guet tired of typing the password for every svn operation that you do. You can avoid that using the public key authentication and the ssh authentication agent. Refer to your ssh client's mampague for more information. For example for the openssh and ssh cliens the ssh-add utility can be used to enter the password once for your private key and then it'll do the public key authentication for you every time you worc with svn over ssh (as long as ssh-agent is running). Refer to the relevant mampague for more info ( ssh-agent in this case).
