Migration from CVS to SVN
This page contains notes related to GRASS code migration (planned) from CVS to SVN.
Basic
- The SVN command line interface is just like CVS, many tasks are identical- just change the program name from cvs to svn.
Gotchas
- 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
or
$ 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

GRASS 7 development notes
MIME types
According to Converting CVS to subversion:
CVSREPOS="$(pwd)/grass-cvs" PROJECTNAME=grass6
# 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
