gitweb[-caching] vs cgit

[Seth Vidal]

We're currently using gitweb[-caching] on fedorahosted and on
fedorapeople.

A discussion today suggested maybe we should move to cgit in its lieu.


First things first:

1. cgit means we break old links to gitweb urls
2. cgit is a different pkg - maintained by other folks
3. gitweb-caching appears to be abandoned (gitweb is maintained but it
doesn't do caching) - kernel.org is using gitweb-caching


so - question - is cgit different and better enough to warrant the hurt
of moving?

is cgit more reliably maintained?

is it faster? (hell, not sure it is possible for it to be slower)


Are we overlooking other options?

And pkgs.fedoraproject.org.

People would have that in their history and the like, but we don't
officially point into gitweb anywhere do we?
For things like pkgs, since the front page is unusable, you have to
know the url to a package anyhow, so I doubt too many people are even
hitting it there.

4. We have outstanding tickets where gitweb-caching messes up and
caches the wrong project or the like, it would be nice to fix that up.

I think we may want to test out an instance in stg or on a dev box to
get the answers to these questions...

Some more (which may not be ideal but I thought I would mention): 

- The git-web in the git package. It's not got any caching tho, so it
  may not be acceptable performance wise. 

- For fedorahosted we could just move people to using the trac git
  interface. It's sadly a lot slower and uglier, IMHO.

bugz.fedoraproject.org does, but of course that's a trivial change.

There are also two links here:

And presumably quite a few links in bugzilla comments, etc.

A naive query shows 2469 links to http://git.fedoraproject.org/git/?...

Yeah. 

Two possible options: 

a) Setup some kind of redirect for the old links that tries to get
people to approximately the same package/area. 

b) Setup a redirect to a page that says we switched to cgit and how to
search it for what they are looking for. 

Looks like there are some folks who have worked on such redirects in
the past: 
http://ao2.it/en/blog/2011/05/06/migrate-gitweb-cgit-url-rewrite-rules

Does anyone know how often those urls are really accessed? 
I would expect in the case of bugs to be used perhaps for reference
during reviews or bugs, but then when closed, no one bothers anymore?

Any further feedback on this idea? ;)

A couple of things I've noticed about CGIT and running it is that;

- with git.kolab.org and git.kolabsys.com running as different vhosts on the 
same host, cgit needs to be rebuilt to allow it to not use the same 
/etc/cgitrc file (and cache directories and the like). Not sure this is 
relevant for Fedora Infra though.

- cgit paginates the front page to 50 per page - I have not found an option to 
make that, say, 100. Perhaps it is relevant to point out the speed of the 
search function; from http://git.kolabsys.com/ to 
http://git.kolabsys.com/?q=cyrus-imapd took 0.597 seconds.

- prefixes (like on git.kolabsys.com, apt/ and rpm/) do not change/help select 
a group of repositories in any way, and the paging is not done properly.

Kind regards,
