Hook script questions
Please don't beat me with the RTFM stick. I've searched for a few days now
and I'm not able to find an answer to my question.
I'm setting up a new subversion instance. It will contain a single
repository with several projects. One of those projects is going to be the
source for a tomcat based website. I want the website to get updated
automatically only when the "website" project is updated. Since I'm not a
coder I'm not entirely sure how to go about doing that.
Is it possible to write a post-commit script that will execute only if that
portion of the tree has been changed?
If someone could point me to an example of how this could be done I would be
eternally grateful.
-Linda

Unfortunately it's not my decision to use a single repository. I do see the
benefits of using multiple repositories. And for future projects it will be
my recommendation to use separate repositories, but at this point what's
done is done.

Why use only one repository? If you have one repo per project,
requirements such as yours become much easier to handle. It is also
easier to maintain projects: Filtering a repo dump to remove bad
commit data, archiving and taking a project offline, mirroring a
specific project to another location, not taking all projects down if
there is repo corruption or other repo down time, etc....

Ryan,
This is exactly the help I was looking for. Thank you so much.
I didn't figure it would be difficult. But as I said I'm not a coder so
thinking in terms of scripts is difficult for me.

Hi Linda! This can definitely be done. The basic strategy for the
post-commit hook would be:
* call "svnlook dirs-changed -r $REV $REPOS" (where $REV and $REPOS
are the parameters passed into the script, as in the example post-
commit hook) to get the list of directories that were changed by the
commit.
* examine each line of the output with for example grep to determine
if the path to your web site was affected
* if so, update a server-side working copy with "svn update"

Nico,
I'm not sure what you mean by client in this context. The tomcat instance is actually running on the same server and I don't have control of what clients people will be using to update the repository. And I'm not actually going to be making changes to the site myself.
The Subversion working copy, whatever machine it resides on, uses an SVN client to do the update.
I'd rather not use a cron job to check for changes since that will require a delay from commit to website update, and my spec sheet requires an "instant" update mechanism. So a post commit script seemed like the right answer.
Ahh. That explains your need: in this case, where the working copy resides on the same machine, a post-commit hook seems very reasonable. I've seen people here looking for ways to push updates to every copy on every other machine, which gets a lot more awkward to do.

Now, now, no sticks on newbies (unless they're into it: I have some SCA
friends). Post-commit is really a server side command: if the clients are
known, you could use an SSH or other remote access tool to push an update to
it.
But instead, if I may suggest, why not have the client simply run a query on
a cron-job basis to see if there have been any changes in that project? Use
"svn info -r HEAD /workingcopy" and parse out it's URI and revision number.
If there is a difference between them, pull the update instead of pushing.
That's how I've done it for a website under subversion.
