As I announced last month[1], we are switching to the git source control
management system for emc2. The date for the transition has now been
set for 6/20/2009, sometime after 12:00 GMT.
Here's how it will work:
* The CVS repository will be made read-only
* A fresh import of the CVS history will be made, then transferred
to the system doing the git hosting
* After a few checks have been made, we'll announce it on IRC and the
mailing lists
* The CVS repository will remain online in read-only mode for at least
a month, so that developers with existing cvs checkouts with local
changes can move those changes into git using 'cvs diff' and 'patch'
If you have existing work in a CVS checkout, consider checking it in
before 6/20; after the transition it will be just a little bit more
difficult to check in as you'll have to transfer it from CVS to git by
hand.
Eventually, the clone URLs will be:
git://git.linuxcnc.org/git/emc2.git
for read-only access
ssh://<developername>@git.linuxcnc.org/git/emc2.git
for push access
Note that these URLs *don't exist yet*; emc2.git will only exist after
the final import from CVS is made.
The "emc2-experimental.git" repository has been moved to the new system
and renamed "emc2-sandbox.git". If you've been wanting to test "git
push", you may now do so--but a WARNING: all the changes made in
emc2-sandbox will be DISCARDED when we make a fresh import for the
switch. The sandbox repository URLs are:
git://git.linuxcnc.org/git/emc2-sandbox.git
for read-only access
ssh://<developername>@git.linuxcnc.org/git/emc2-sandbox.git
for push access
The web interface to the git history is http://git.linuxcnc.org/ (click
"tree" for a slightly more cvsweb-like view)
All developers with ssh keys on the cvs server have had their keys
already set up on the new system, so you can try this out right away.
I will try to be on IRC for as much of the weekend of 6/20 and 6/21 as
I can, to help with questions about using git. There are also a large
number of online resources to help with git:
