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 CVS repository structure

|
+---/grass_doc
|
+---/libgrass

+---/web

Testing SVN repository

• grass/grass should be renamed to grass/grass5

Question:

• Migrate all directories or only actively used (grass, grass6, newsletter, web)?
• Create separate repositories (grass5, grass6, grassweb, grassnewsletter, grass7) or one repository (grass-svn)?

Proposed structure

Question: exclude selected branches/tags (which one?)

According to undocumented these branches/tags are suggested to be excluded:

--exclude="Mike" \
--exclude="grass" \
--exclude="unlabeled-.*" \
--exclude=devices_cleanup_20000420 \
--exclude=post_compare_glynn_head_2002_11_27 \
--exclude=post_compare_glynn_release_2002_11_27 \

--exclude=release_grass5beta11pre2_28_january_2001 \
--exclude=start \
--exclude=testbranch_5_0_0stable \
--exclude=grassreleasebranch_5_0_0 \

A lot of dependency problems:

Question: Exclude more tags (which)?

• I guess tags "freetypecap", "lastworking", "pre_fileinfo_change" and maybe also "pre_vdigit_changes_.*" could be also excluded... --ML

Add other switches (e.g. --encoding) ??

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/' | \

# 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.

   egrep -i '^'"$EXT1"'$' | sort -u > step3

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

SVN hosting

There are two main options to host the new SVN repository.
