Freddie,

 

For setting permissions we do it through a bunch of bash scripts (long
live bash) that have in the base one the setting of roles. Here is the
code cut and pasted (note that we have /var/trac as our root):

<code>

### Set up roles

 

#Remove anonymous permissions

trac-admin /var/trac/$1 permission add developer authenticated

 

#Grant privileges to editor

trac-admin /var/trac/$1 permission add editor MILESTONE_MODIFY

trac-admin /var/trac/$1 permission add editor ROADMAP_ADMIN

trac-admin /var/trac/$1 permission add editor TICKET_ADMIN

trac-admin /var/trac/$1 permission add editor developer

 

########## COMPONENTS ##########

 

#Remove all existing components

trac-admin /var/trac/$1 component remove component1

trac-admin /var/trac/$1 component remove component2

 

########## MILESTONES ##########

 

#Remove all existing milestones

trac-admin /var/trac/$1 milestone remove milestone1

trac-admin /var/trac/$1 milestone remove milestone2

trac-admin /var/trac/$1 milestone remove milestone3

trac-admin /var/trac/$1 milestone remove milestone4

 

########## PRIORITIES ##########

 

#Change some

trac-admin /var/trac/$1 priority change major high

trac-admin /var/trac/$1 priority change minor medium

trac-admin /var/trac/$1 priority change trivial low

 

#Remove the others

trac-admin /var/trac/$1 priority remove blocker

trac-admin /var/trac/$1 priority remove critical

 

########## VERSIONS ##########

 

#Remove all existing versions

trac-admin /var/trac/$1 version remove 1.0

trac-admin /var/trac/$1 version remove 2.0

</code>

 

I then have a bunch of "one off" scripts for dealing with single users
which are just added to the various roles. You can guess how those look
as well. 

 

I've contacted our sysadmin about your password/authentication
questions. I can say that we have a system where people need a password
just to see our trac site. Then they get upgraded through a separate
channel up the list of priveledges. I don't think that this will work
for NeXus since we want to have more open access for people looking at
the projects. 

 

About the wiki portion of trac: we use it partially as a developer
whiteboard, partially as a document repository, and partially to chart
things that span across multiple milestones. To get a real idea of what
it can be used for I suggest looking at the trac project page more. Some
of my favorite pages are http://trac.edgewall.org/wiki/NewWorkflow and
http://trac.edgewall.org/wiki/InterTrac. The second is more along the
lines of documentation for the public. I suggest we keep that sort of
information on the media-wiki.

 

I'll let you know when I have more information.

Peter,

 

Re: passwords: CVS stored your password in a ".cvspass" file in your
home directory when you first did a "cvs login" and may well send it
every time (or maybe once and use a token; not sure). Subversion uses
whatever method you set on the web server ... If you use https with
subversion you are using a public key to encrypt the data, but in our
case you would still be sending a password (stored somewhere on your
computer) as we are using http basic auth. We could issue certificates
and use them instead of "basic auth", but I'm not sure we need to.  

 

What do you do about accounts and password for your TRAC - are they
loaded from some central area? I'm sort of conscious of the possibility
of being spammed and so ideally would require an account for submitting
issues as well, hence the idea of linking to mediawiki as that has an
account creation, verification and "send me a new password" system
already in place. Your roles sound reasonable ... if you have a script
that creates the roles and adds permissions it will save me a load of
trac-admin commands. I guess we need to decide how we will use it Re:
definitions and also what is the status of the TRAK WIKI (like do we
disable it totally or use it as a developer whiteboard?)

Freddie,

 

It is useful to have a trac site for the definitions as well. We've set
up "roles" to promote "appropriate use of trac. The roles are named
(from least to most able): [everybody, authenticated, developer, editor,
admin]. What happens is that "everybody" can create tickets and view
most of the site, "authenticated" can annotate tickets, "developer" can
change ticket state, "editor" can work with milestones. I don't think it
is necessary to say what "admin" can do. I can send you a list of
information for setting this up.

 

The other statement is that I am curious about passwords since I thought
that I was using a public key to authenticate. Is this true?

 

P^2

I've set up two repositories:  http://svn.nexusformat.org/code
<http://svn.nexusformat.org/code>  and
http://svn.nexusformat.org/definitions/
<http://svn.nexusformat.org/definitions/>  usernames and passwords are
currently the same as your old CVS ones. You should add "/trunk" to the
URL when you check it out e.g. http://svn.nexusformat.org/code/trunk
<http://svn.nexusformat.org/code/trunk>  Post commit hooks, such as
emailing you on changes, are not currently set up but you should be able
to check out and commit files.

http://trac.nexusformat.org/ <http://trac.nexusformat.org/>  points at
just the code repository ... do we see any need to use trac for
definitions? If so, I will create separate
http://trac.nexusformat.org/code/ <http://trac.nexusformat.org/code/>
and http://trac.nexusformat.org/definitions/
<http://trac.nexusformat.org/definitions/>  areas. To login to trac you
can use your subversion username and password, though login is not
currently required to submit issues.

With regard to usernames and passwords, I believe I can make the
trac/subversion ones the same as those in MediaWiki (either by using
mod_auth_mysql or making both use ldap for username/password); either
way will require a one-off reset of everybody's passwords. Do you want
me to go ahead and investigate this further?

With regard to moving the nexus mailing lists, I am awaiting some
changes on our site central mail gateway so that it will accept incoming
mail to user at nexusformat.org <mailto:user at nexusformat.org>  and not
think it is an illegal attempt to relay spam through us

Cheers,

Freddie
