Subversion Users,
We are working on a large stormwater modeling program where we will be
keeping track of a lot of PCSWMM file type models. We are exploring
version management options and have come across the SVN community. I
understand this is great for text-style files, however, I would like
to know if you have seen users utilize this for engineering plans such
as PCSWMM?
Many version control systems, Subversion included, work best when the
new version of a file looks much the same as the previous version.
Otherwise you could be storing multiple full versions of the files.
Some features of Subversion (like "show lines that changed") aren't
available for binary files, but if the changes in a binary file are
limited to specific sections, you still get space-saving benefits in the
repository; see
http://help.collab.net/index.jsp?topic=/faq/svnbinary.html and
https://svnbook.red-bean.com/en/1.7/svn.forcvs.binary-and-trans.html
(both links are old, but binary file handling shouldn't be worse now
than then).
A quick search didn't tell me anything about the PCSWMM format; how much
of a file changes between model runs? Is it text or binary? Are the
files very large (gigabytes or more)? Are they inputs to software, or
outputs? Generally it is assumed that output files can be recreated
given the full input configuration, so program outputs are often left
out of the repository.
