Renaming a category?

Renaming a category?

[Hans-Albert Schneider]

What is the preferred way to rename a category?

For GNATS 3.113, I am currently aware of the following procedure
(assume renaming from "A" to "B"):

1) Create a new category "B".
2) Edit each report in "A", changing the category to "B".
3) Remove category "A".
4) Run gen-index.

(I once tried to just rename the directory from "A" to "B" (and
the entry in gnats-adm/categories, of course), and found that
gen-index produced A/17 instead of B/17, because the Category
field had not been changed.  This was probably with an earlier
version than 3.113; is gen-index now more clever about this?)


Is there an easier way?  Maybe with version 4?

In step 2), do I need to invoke edit-pr and manually edit all
reports, or can I just run something like

    for each report $n in category A,
	sed -e "/^>Category:/ s/A/B/"  < A/$n  > B/$n
	rm A/$n


Thanks for your hints,

I don't think there is a better way. I have had to do the same thing myself 
on a few occasions. Automating step 2 should be OK, though. Gnats4 has no 
improvements with regards to this. This might be an idea for a new admin 
tool in a future version.

It's time for a summary:

Summary:
	There is currently no other way, neither in version 3.x
	nor in version 4.

    [simple minded for-loop with sed removed]

Summary:
	To take care of locking, edit-pr or pr-edit --lock should
	be used.  Otherwise, automating is OK.

I already had the idea to use edit-pr with the EDITOR variable
set to something like the sed command.  I meanwhile have written
a shell script to do this.  (This also was an exercise for me to
write a script that tries to be a bit security conscious, so its
purpose was not just to re-invent the wheel.)

Tools:
	There is a PERL script by Sherry Wasserman.
	There is also my script now. :-)

Of course we are interested, could you send me it, please?

I agree. Presumably, it's specifically created for Gnats 3, but no major 
changes should be necessary for v4.

I assume Milan will grab hold of this when he has time.

This should be added to the contrib directory (if there still is one) or
become part of gnats itself!

...RickM...

RE: Renaming a category?

[Wasserman, Sherry]

Hello,

If others have access to the gnats database while you are changing the
category, you should probably be concerned about locking the PRs.

If you change the category field manually (by using gnatsweb or edit-pr), 
the normal PR locking mechanism will prevent changes (yours or theirs) from 
being overwritten.  The PR will also be moved to the new category location 
and the index entry will be created by the software.  You won't have to do
gen-index.

If you use sed,  you should either lock the PRs that are going 
to be changed (pr-edit --lock), or lock gnats by creating the gnats.lock
file 
in the gnats-admin directory.  (Don't forget  to remove the locks it when
you're done.)

I recently created a tool to move all PRs from one category to another 
with the following command:
	perl catmove  [-d gnats_root]  <old category> <new category> ...

I'll be happy to send this, if you are interested.
