[resending, since the original was misclassified as spam by a bunch
 of spamassassin "chickenpox" rules.  I suspect it objected
 to the list of email addresses, so rather than including them
 inline, I'm using an attachment, now. ]

Hi,

I'm preparing a read-only git mirror of gdb's CVS repository.
It will be automatically sync'd every ~30 minutes, just as the other
http://sourceware.org/git/gitweb.cgi mirrors are: glibc, lvm2, dm,
automake[*].  This gdb.git mirror covers all branches and includes
all history.  For the record, I used a patched version of parsecvs to
do the initial conversion.  Automated incremental updates are handled
by a wrapper around "git cvsimport".

[*] Note that the automake.git mirror is obsolete, and will
be removed in a couple months.  It switched to git for good,
and is now hosted at savannah.org.

Part of the conversion job involves compiling the mapping from login name
(used in the cvs repository) to the "First Last <email>" that git uses.

Below, I've included a first cut at that mapping, produced mostly
automatically, partly using RealName+email from ChangeLog entries
committed by "login name".  The automatic process uses heuristics,
and is far from perfect.  I'm posting the result here, so people have
a chance to make corrections now.  It's important to get it right early,
because redoing the mapping requires changing nearly every SHA1 in the
resulting git repository, and that is very disruptive.

Note that this records the cvs committer name as the git "Author".
That is inaccurate when the cvs committer merely checked in a change
written by someone else.  If there is sufficient demand, we can look
into correcting those so that git shows the real "Author:" of the
proxy-committed changes.  That is possible only when the ChangeLog entry
includes the real author's name and email in an easily extracted form.

So if you can take a minute or two to sanity-check this
list, it may avoid some hassle latter:

Finally, note that with this list the only nameless
username is "gdbadmin".  However, any time a new
username cvs-commits a change, that username
will appear in the git repository with no associated
'First Last <email>' information.  If/when that happens,
let me know and I can update the map so that future
cvs commits include the usual information.
-----------------

Since I wrote the above, I've made the repository available:

Here's the gitweb interface:
  http://sourceware.org/git/gitweb.cgi?p=gdb.git

As it suggests at the top, you can get a copy via any
of these URLs:

  git://sources.redhat.com/git/gdb.git
  ssh://sources.redhat.com/git/gdb.git
  http://sources.redhat.com/git/gdb.git

E.g., run this

  git clone git://sources.redhat.com/git/gdb.git

That downloads ~73MB to create a copy of the repository in gdb/.git,
and puts all of the checked out files in gdb consuming a total of ~200MB.

If there are enough changes to the Authors list, I may regenerate
everything within the next couple weeks.

If any of you would like to rely on this, please ensure that all
of the files you care about are in the git repository.  For example,
I heard that three tcl-related directories need not be included, so I
excluded those along with the likes of ld, gold, gas, etc.

Also, please ensure that any branches you're interested in are
accurately reproduced in git.

Jim

Thanks!
Some of those are indeed newer, so I've applied most of the changes.

However, I'm sticking with the tuliptree.org address,
since that's the one listed in gdb/MAINTAINERS.

Also, a few of your entries didn't appear in the selection
of directories that I'm currently mirroring, so I omitted them.

I'll wait a few days, and then regenerate the repository.

This is awesome. I look forward to use this mirror.
I also like the fact that git log show history for the binutils side
which affects GDB as well.

Do you know if there will be disruption if GDB moves to Subversion?

I just compiled from this repo in ppc-linux and ppc64-linux and I saw no
smoke, so it seems sane there.

Thanks for doing this.

There would be some disruption, because the current
synchronization method is tied to GIT and CVS.
But it wouldn't be too bad, since git-svn provides
trivial bi-directional access.
Any branches relative to the cvs-derived git repo
could be migrated to a git repo converted from svn.

Of course, any SHA1 references into the cvs-derived repo
would be worthless (but they could theoretically be translated
to point to the same objects in an svn-derived repo).

Good to know it works.  Thanks.

It's sync'd once per hour, now.

It's more like 100MB for .git and 250MB for the whole thing.

I've regenerated the repository using an updated mapping, so if you
have a cloned directory, don't bother trying to pull from it.
Instead, just remove it and clone again.

BTW, for read-only access, use the git:// URL,

    git clone git://sources.redhat.com/git/gdb.git

unless a firewall forces you to clone via the inferior http:// protocol.

A number of those addresses are out of date, and no doubt some of the 
others will be out of date shortly.

Perhaps it's less trouble to simply use <username>@sourceware.org in all 
cases?

The primary goal in this initial conversion process is to make the
[cvs commit login-name] to [real "First Last" name] map accurate.
Think of the email portion as more of a historical record/artifact
(as in the ChangeLog) than something to be kept up to date
like an address list.
