[kepler-dev] Conversion of Ptolemy II Tree to SVN this week

[Derik Barseghian]

Hey Christopher,

I'm not sure how to verify that cvs2svn treated all your files as  
binary, but I think it did because the default to the --default-eol  
switch is "binary" (and you didn't use the switch and so I assume it  
used the default).

I just found this section of the svn book:
http://subversion.tigris.org/faq.html#auto-props

I think (correct me if I'm wrong svn experts) that section illustrates  
one limitation of your svn repo as it is now: keywords like $Id$ will  
not be automatically changed in your ascii files because the  
svn:keywords property is not set on these files.

You don't *have* to use --default-eol=native switch when you convert,  
but it has the benefit of setting the svn:keywords property for ascii  
files. Also beware: the manual warns to *not* use this switch if you  
haven't ensured all binary files in your cvs are indeed marked as such  
(-kb), your svn repo may be corrupt otherwise.

Using other switches, cvs2svn can also try to deduce which files are  
binary for you during conversion. I didn't try that, I manually looked  
at every kepler file (in eclipse) and changed the cvs ascii/binary  
property on those that were set incorrectly so that I could use -- 
default-eol=native ie "Full conversion" method described on the  
cvs2svn page.
