Re: Need help for migration from CVS to git in one go (ie, FORGETTING CVS history)

Since my first email where I said that we wanted to migrate from CVS to a 
distributed SCM, we have had a lot of discussions with developers and my 
chief (which happens to be a developer too). We have come to the following 
conclusions:

* git has credentials (heck, it "runs" the Linux kernel, Wine,
  Samba, and other);

The main contenders among top OSS version control systems seems to be
Git, Mercurial and Bazaar-NG for distributed SCM, and Subversion for
centralized SCM.

* the "distributed" part of it is indeed an advantage (planned
  developments with huge technical/functional impacts);

* 52 CVS modules, fine; but then this can become one and 52
  subdirectories in them and still act as separate modules from
  the build system point of view (which I have implemented, so
  I can change it);

I think that those CVS modules should become separate repositories,
perhaps joined together using submodules. This is one of more
difficult things during conversion.

Note that in Git commits are always whole tree (whole project)
commits.

* second: even though this may be a "non problem", we use Bonsai,
which has the ability to see what was commited by whom, given a time
interval (from d1 to d2): the base gitweb allows to search by
commiter, which is good, but it has no date boundaries: do tools
exist for git that can do this? If not, that wouldn't be a big deal,
however...

First, there are more web interfaces than gitweb, see
http://git.or.cz/gitweb/InterfacesFrontendsAndTools

Second, you can do this from command line, using combination of commit
limiting a..b and a...b, or --since=<date> or --after=<date> and
--before=<date>, commit message searching --author, --committer, and
--grep, and path limiting "git log -- <pathspec>".

Third, it would be not that hard to add more advanced search support
to gitweb; this is even one of planned features.

* third: also Bonsai-related; Bonsai can link to Bugzilla by
matching (wild guess) /\b(?:#?)(\d+)\b/ and transforming this into
http://your.bugzilla.fqdn.here/show_bug.cgi?id=$1. Does gitweb have
this built-in? (haven't looked yet) Is this planned, or has it been
discussed and been considered not worth the hassle?

This is (under name of 'committags') in gitweb TODO; gitweb-xmms2
support this IIRC or supported this (for Mantis and not Bugzilla
though...)
