I'm developing a php website that I have under subversion version
control. I'm working on an image upload functionality, and in the
middle of it I realized that any files that a user uploads will not be
under version control, and if I checkout or export the site from
version control, and deploy it, it won't bring any of the uploaded
files with it.
I'm looking at php subversion functions, but the manual says that
they're experimental, and my webhost hasn't deployed them.
What's a workaround for this? I'm thinking that I'll have to have a
parallel site for image hosting. For example, I'll have
images.website. com, hosted under a separate filesystem directory, and
then in the actual website that a user would peruse, any img src would
reference images.website. com . When I accept my uploads, I'll do my
filesystem copy to the images filesystem link.
Thoughts?

Why would you want it to? This is user data, not data that is
actually part of the application. In any case, why would users be
interacting with a copy of the application that is a Subversion
working copy?
I think that I must have misunderstood, because it sounds like you
want to use Subversion as a packaging and distribution mechanism, and
that's not what it's for.

Exactly. Subversion is there to facilitate rolling new versions out and
develop them. What you probably want is a good backup facility. The fact
that subversion never forgets anything makes it a less-than-optimal
backup system. Off course it was never *meant* as a backup system.

I think that I must have misunderstood, because it sounds like you

Well, here's the problem, as I perceive it:
Say my website is served from a directory called /home/user/website .
Users of the website need to be able to upload images, which in the
current incarnation of the website I specified to be served /home/user/
website/images. This directory currently holds all images served with
the site, not just user uploaded images.
My 'packaging and distribution' practice currently consists of 'svn
export http://svn-host/website/trunk', and then linking that to the
website directory, e.g. 'ln -s website-trunk-revision-189 /home/user/
website'.
So the problem is, unless user uploaded images were put under version
control, which I would have to do by migrating the image from the live
to the development site, and then putting it under version control,
the user uploaded images wouldn't be in an exported revision of the
website.
So my thought would be rather than try to include them in version
control, move the functionality of accepting and serving user uploaded
images from a subdirectory of the website to its own domain, and just
not keep it under version control.
So when I export the website, it won't include any uploaded files,
unless they were put under version control.

Well, I guess I don't know how others roll out websites from
subversion, but I'm just using 'export', and then creating a symlink
of the svn export to the webhost directory. So the problem is, if I'm
serving user-uploaded images out of a subdirectory in the website
( e.g. /user/home/website/user-uploaded-images ), unless new uploads
are put under version control, they would not exist in an export when
I roll out a new release of the website. So I guess if you want to
call that 'backup' functionality, I see that side of it, but to me, it
isn't any different than just making sure all the pieces of your
project exist when you do an export, which I think might be an
implicit functionality of version control.
When I use svn export to roll out a new version of the site, I could
copy the user uploaded images into the image directory, but that adds
an extra step to releasing a new site, and I like to keep things
simple. I have enough to worry about when I roll out a new version. So
my thought now for user uploaded images is simply not to serve them
from within the web directory, but put up a whole other host that's
not under version control, and serve them from there. la*****@gmail.c om wrote:

As others have indicated - the problem is you're using subversion for
something other than what it's intended for. What you need is a good
backup strategy, not a version control system.
But in any case, this has absolutely nothing to do with PHP, so this is
the wrong newsgroup, anyway.

I would just get the desired revision from svn and copy the source
files to the production directory. You might need to clean out the
production directory first if you've removed any files.

You're making this too complex. Subversion is for controling
revisions of your source code and related files (e.g. design docs),
nothing else. Once you put the application into production and have
begun accumulating user data, just copy the source files from a
working directory to the production directory using cp -r or a shell
script.

I'm using subversion for version control. If my website has an image
that's part of the website, it goes under version control, like any
other file that's part of the website. When I say it belongs under
version control, I mean that "Version 3.x has X version of this logo,
Version 4.x has another version".
If versioning images and other binary files are not the purview of
version control, then why does subversion have functionality for
versioning binary images, such as locking, etc.?
I'm not using it for 'backup' in the sense of "Oops! I deleted this
file accidentally. I need it to get it back, so let me go into the
backup and retrieve a copy of it. What is the definition of "backup"
that you're using here?
I don't see how this is a backup issue rather than a version control
issue. I think you might argure the point that this might be a
packaging and distribution issue as Charles Calvert did earlier, but
in this case, it isn't a c++ solution that requires a build
environment -- here, "svn export" *is* the packaging and distribution.
If you're using php and svn, what extra packaging and distribution
would you need for a site that's not released to anybody else, or
installed on any other systems?

Well, I can do all that in one fell swoop by creating a symbolic link.
I don't have to worry about whether or not I've deleted anything in
version control that I then need to remove in the production; it's
already done for me. If I had to delete files what were already
deleted in version control, then in my mind, I'm doing manual labor
that the computer should be doing anyway.
Also, by using symbolic links, I can deploy, test, and fallback to the
old directory by re-linking very easily if I need to.
Finally, by using an adequately named directory to symlink to, I know
what version I have deployed as production. If /home/user/website/
production is a symlink to /home/user/website/trunk-R255, then there's
a pretty good chance that it's revision 255 that is currently in
production. If I were just copying files into the website directory, I
would have to have another way to know or guess what revision was
actually deployed. I could reconcile my svn history against my bash
history, and try to extraploate what version is currently deployed,
but that takes some leg works and concluding. Of course, both ways are
subject to failure if you don't practice your procedures properly, but
I think symlinking is harder to screw up.
So, three good reasons to use svn exports in and symbolic linking to
deploy a website.
You're making this too complex. Subversion is for controling
revisions of your source code and related files (e.g. design docs),
nothing else. Once you put the application into production and have
begun accumulating user data, just copy the source files from a
working directory to the production directory using cp -r or a shell
script.
Well, I didn't *intentionally* make it to complex; my assumptions
about website design and structure sort of led me to the place that
I'm in now. :)
I'm making a dymanimc website where users can input data. The source
code of the website is under version control, and the user-generated
data is stored in MySQL. So far, so good. If I needed to re-generate
the website for any reason ( backup, new webhost, errant rm -rf ), all
I needed was a recent export from subversion and the latest MySQL
dump.
So now I think I'm beginning to understand the philosophy. In the
past, I could get away with keeping all the website images under /
images, or some similar structure. But now that I'm accepting user
data that I can't or shouldn't put into MySQL, I need to find a third
place to store things. I liked the simplicity of having the whole
website existing as svn export + mysqldump, so I was hoping there was
a way I could keep this new kind of data within that system. But I
can't. Now, the website must be mysqldump + svn + some other thing.

That's what synchronizing is for. The computer can easily check which
files have been modified or deleted from the working copy and upload all
required changes to the production server. There are various tools
available for this task.
>Also, by using symbolic links, I can deploy, test, and fallback to the

This should happen on a testing server. You hardly need multiple
versions on the production server.
>Finally, by using an adequately named directory to symlink to, I know
what version I have deployed as production. If /home/user/website/
production is a symlink to /home/user/website/trunk-R255, then there's

You could use tags on your repository and then simply assume that it's
always the latest tagged version which goes production. When you reach
the next stable release, tag it and deploy it. Quite easy.
