I am using an SVN repository for my web development work. I have a development site set up which holds a checkout of the repository.

I have set up an SVN post-commit hook so that whenever a commit is made to the repository the development site is updated: 

cd /home/www/dev_ssl
/usr/bin/svn up

This works fine but due to the size of the repository the updates take a long time (approx. 3 minutes) which is rather frustrating when making regular commits. What I'd like is to change the post-commit hook to only update those files/directories that have been committed but I don't know how to go about doing this. Updating the "lowest common directory" would probably be the best solution, e.g.

If committing the follow files:

  • /branches/feature_x/images/logo.jpg
  • /branches/feature_x/css/screen.css

It would update the directory: /branches/feature_x/

Can anyone help me create a solution that achieves this?

Update:

  • The repository and development site are located on the same server so network issues shouldn't be involved.
  • CPU usage is very low, and I/O should be ok (it's running on hi-spec dedicated server)
  • The development site is approx. 7.5GB in size and contains approx. 600,000 items, this is mainly due to having multiple branches/tags

You might use svnlook dirs-changed and svn up -N to update only the contents of each folder changed:

cd /home/www/dev_ssl
svnlook dirs-changed [REPOS] -r [REV] | xargs /usr/bin/svn up -N

Or, if per-file might be better for you (using sed to strip action characters):

svnlook changed [REPOS] -r [REV] | sed "s/^....//" | xargs /usr/bin/svn up

#!/bin/bash

REPOS="$1"
REV="$2"

# A - Item added to repository
# D - Item deleted from repository
# U - File contents changed
# _U - Properties of item changed; note the leading underscore
# UU - File contents and properties changed

# Files and directories can be distinguished, as directory paths are displayed with a trailing "/" character.

For Windows:

for /F "eol=¬ delims=¬" %%A in ('svnlook dirs-changed %1 -r %2') do svn export "file:///c:/path/to/repo/%%A" "c:/svn_exports/%%A"  --force

Just copy the above into your post-commit hook batch file (or window for VisualSVN) and you're done - you'll get the updated directory exported to c:\

You could try using %1 instead of c:/path/to/repo above, but I found that it didn't work because VisualSVN give the %1 path with back-slash path separators, and svnlook gives them with forward-slashes. This doesn't seem to work right so I hard-code the repo path (I got "The filename, directory name, or volume label syntax is incorrect" errors)
