Importing RCS files to a repository

STILL WORKING ON THIS PAGE

Initial Import

Just importing the miriad tree as it stands is unsatisfactory, because we lose the revision history. So we use cvs2svn.

Note: there is a ​bug in the version of cvs2svn available in the Debian sarge release that causes the import to die partway through. The version available in Debian etch works correctly.

 % mkdir miriad
 % rsync -av /nfs/atapplic/miriad/ miriad/

 # method 1
 # we'll create a new repository in a directory named 'svnmiriad'
 % cvs2svn -s svnmiriad  miriad

 # method 2
 # we can create an empty repository named 'svnmiriad' and load via a dumpfile
 % cvs2svn --dumpfile=20071123.svndump miriad
 % svnadmin load svnmiriad < 20071123.svndump

 # method 3
 # add to an existing repository
 % svnadmin create svnmiriad
 % cvs2svn --existing-repos -s svnmiriad miriad

To do later imports, we would have to do something like this:

  % mkdir miriad2
  % rsync -a /nfs/atapplic/miriad/ miriad2/
  # create a new repos
  % cvs2svn -s svnmiriad2 miriad2
  # assuming a repository named 'svnmiriad'
  % svn merge -rM:N svnmiriad2 svnmiriad  #???
  # M and N are revision numbers in the svnmiriad2 repository.

Not everything in the miriad directory gets imported (e.g. the binaries), because they have no RCS file.

next phase

need to remove the compiled binaries

No - the binaries never get checked into RCS so they aren't imported to svn.

need to check out the code (and svn add all the files?)

No - just do the cvs2svn dump. that does the checkout but it leaves the source in the '.rcs' directory. Must move it from there. The dump leaves darwin_ppc, darwin_x86 there as well. These contain just a short GNUmakedefs file.

check for things that should have been in RCS and weren't.

This reveals some files with ,x as their RCS suffix instead of the default ,v. etc/archive is not (all) in RCS. linpack linux, linux64, sun4sol, unicos platform-specific directories aren't there but the darwin_ ones are.

check the programs are the same at the current revision.

need to change the chkout, chklog targets need to add handlers of .svn directories

The GNUmakedefs defines a 'MIRFTP' variable; the comment about solaris-only is wrong.
