Is it possible to delete last revision?
Hi,
I'm new to subversion and would like to know if it is possible to delete
the last revision from the repository? I've mistakenly commited some
code with known problems (my stupidity) in the repository, and would
like to delete it now just to keep the repository clean with last stable
version. If its not possible then I guess I will have to make another
revision.
Also, is it possible to write comments to revisions after commit?
Thanks,
Zia

You can't remove revisions. But you can commit a new revision that
'undoes' the change. Read about it in chapter 4, 'undoing changes'.

You can edit any commit log-message by running
svn propedit --revprop -r REVNUM svn:log

Hi,
Thanks for your replies. I've copied the .tmpl file to
pre-revprop-change in hooks directory. Restarted the svnserve and use
the following command in the checked out (working) copye of the code. I
get the following error...
[root@zs irman]# svn propedit --revprop -r 42 svn:log --username xx
--password xxxx
No changes to property 'svn:log' on revision 42
I've set SVN_EDITOR to gvim but i get the No change message before gvim
loads up. Any ideas?
Thanks,
Zia

You can't delete a revision, but what you can do (if nobody has committed
since) is to perform a dump of the repository (look at the documentation
for 'svnadmin dump'), specifying only the revisions that you want (ie if
you've just mistakenly committed r6, you'd dump r1-5, "-r 1:5"), and then
delete/restore the repository from that dump - that will effectively
remove the last revision. (But be careful, and preferably back up your
repository before doing this!)

Yes, use "svn propedit --revprop -r <REVNUM> svn:log". But by default this
is not permitted - you'll need to set up a pre-revprop-change hook. That's
much easier to do than it sounds: go into the directory <repos>/hooks, and
rename the file "pre-revprop-change.tmpl" to "pre-revprop-change", and
ensure it's executable. [ I'm assuming you're running Linux/other Unix
here, if you're running Windows the procedure will be different... ]
