This page contains notes related to GRASS code migration (planned) from CVS to SVN.


  • The SVN command line interface is just like CVS, many tasks are identical- just change the program name from cvs to svn.


  • cvs2svn is known to break binary files (images) which were not imported into the CVS with the -kb flag. Luckily Glynn fixed most of these some months ago.
  • Files using keyword substitution, such as $Date$ in the description.html files, will have to have support for that enabled manually, once per file (or write a find routine with | xargs svn ...).
$ svn propset svn:keywords "Date" filename.txt
$ svn commit


$ find . -name '*.c' | xargs svn propset svn:keywords "Date" 
$ find . -name '*.html' | xargs svn propset svn:keywords "Date" 
$ svn commit
  • how to maintain timestamps of files? We want to keep the last modification date, not the date of local download

MIME types

According to Converting CVS to subversion:

# Find all extensions. Also include filenames without extension.
# The E (extension) and S (slash) trick is to get GNU sort to separate
# them, although this is not really necessary. But note that at the
# same time it removes the leading slash from filenames without extension.
find $CVSREPOS/$PROJECTNAME -type f -name '*,v' ! -name '.cvsignore,v' | \
   sed -e 's%.*\([./][^.]*\),v$%\1%' -e 's/\./E/' -e 's/\//S/' | \
   sort -u | sed -e 's/^S//' -e 's/^E/./' > step1

# Compose an extended regular expression that matches any "extension"
# as found by the previous step.
EXT1="($(grep '^\.' step1 | xargs echo | sed -e 's/^\.//' -e 's/\+/\\+/g' -e 's/ \./|/g'))"

# Find all mime-types and related extensions that really exist.
egrep -i '^alnum:[^[:space:]]*space:+([^[:space:]]+ )*'"$EXT1"'($| )' /etc/mime.types > step2

# Extract the list of extensions from the previous step,
# filtering out the extensions that we don't have.
for ext in $(sed -re 's/^[^[:space:]]*space:+//' step2); do echo $ext; done | \
   egrep -i '^'"$EXT1"'$' | sort -u > step3

# Compose an extended regular expression from the previous step.
EXT2="($(cat step3 | xargs echo | sed -e 's/ /|/g'))"
# Find all "extensions" that weren't really extensions
# (or for which we don't know a MIME type).
grep '^\.' step1 | egrep -iv '^\.'"$EXT2"'$' > step4

# And turn it into an extended regular expression.
EXT3="($(sed -e 's/\./\\\\./' step4 | xargs echo | sed -e 's/ /|/g'))"

# Create a list of files for which no MIME type is known.
find $CVSREPOS/$PROJECTNAME -type f -name '*,v' ! -name '.cvsignore,v' | \
   sed -e 's%.*/\([^/]*\),v$%\1%' | egrep -i "$EXT3"'$' | sort -u > step5
