They are not lost (the app is designed so that things are not easily
lost), and can be found by writing the old full URL:


The easiest way to make the transition is to copy the docstrings via SQL
on the server.

I just copied the numpy.core.defmatrix.* docstring revisions and
comments to numpy.matrx.defmatrix.*. For reference, it can be done with
two SQL statements on the database:

        insert or ignore into docweb_docstringrevision
        (docstring_id, text, author, comment, timestamp, review, ok_to_apply)
          'numpy.matrx.defmatrix' || substr(docstring_id, 21, length(docstring_id)),
          text, author, comment, timestamp, review, ok_to_apply
        from docweb_docstringrevision
        where docstring_id like 'numpy.core.defmatrix%';

        insert or ignore into docweb_reviewcomment
        (docstring_id, text, author, timestamp, resolved) 
          'numpy.matrx.defmatrix' || substr(docstring_id, 21, length(docstring_id)),
          text, author, timestamp, resolved
        from docweb_reviewcomment
        where docstring_id like 'numpy.core.defmatrix%';

Moving would have been two one-liners, but copying maybe better conforms
to the append-only policy. Also, the sqlite version on the server
doesn't support a replace() function, yuck.

I think everything should be OK now -- please let me know if something
is broken.

I'll put the following to my crontab, let's see if it helps...

        15 14 * * sun	test `wget -q -O- 'http://docs.scipy.org/numpy/patch/' | grep -c '<tr>'` -lt 100 || echo "Hey man, lots of stuff is waiting at http://docs.scipy.org/numpy/patch/" | mail -s "Lots o' Stuff waiting in Pydocweb" pauli@localhost

Anyone else with SVN commit access is welcome to do similarly :)

You have reviewer rights, so you can go and click the "OK to apply"
buttons, to flag those changes that are better than SVN.

Also, check that no unwanted or dangerous code (eg. careless handling of
temporary files, etc) is added to the examples -- they may eventually be
executed after committed to SVN.
