Ok. Here's a bit of PHP code I constructed. This comes from a
"source control home page"; this section of the page displays a list
of recent clean builds, and what was committed since each build. It
is driven off a naming convention for tags: tags named
/tags/last_clean_build/xxx represent a successful build of branch xxx
(or of the trunk, if xxx == "trunk").
The code uses shell commands to extract the source path and rev from
the copy operation that creates the tag, and then invokes "svn log" to
get the log starting with the rev after that.
I'll freely admit the code is a bit messy; by way of excuse it's my
first PHP effort.
I also looked at doing this in Python. Once I dig a bit deeper and
find documentation on the Python bindings to Subversion (if there is
any such -- does anyone have pointers) I'll give that a try too.
