As noted recently by Alex, we're carrying around significant
quantities of unwanted cruft in the git repository. If you
have a current clone, you can see it by:
git whatchanged -- zy1000
That's around 100 MBytes of useless stuff that gets pulled,
and then carried around in repositories. We want to get rid
of that before 0.3.x releases go out. (Also a few other noise
commits.)
This is a one-time fix, addressing some SVN conversion issues;
such changes should not happen again. Since we only recently
switched over to use git, we don't expect many folk to have
significant branches yet; such branches would be disturbed by
this switchover.
So here's my rough plan on how to fix:
- At time T, I rename the "openocd" repository to "openocd-old".
You'll be able to tell "T" since "git pull" (or clone) using
the previous git:// URL won't work. The "openocd-old" repo
will be a temporary backup, which we expect will vanish by
the end of November. It may help if you need to rebase some
branch.
- At time T+1, I provide a new "openocd" repository which is
equivalent to "openocd-old" ... but is rebased to purge those
useless commits, and their data. Commit IDs before about a
year ago will be unchanged. All newer ones will be different,
because they won't have have those useless commits in their
ancestry. (I'll use the "grafts" file I previously posted.)
- From time T+2 and later, everyone will want to get new clones
of that repository. I'll send out an email announcing this,
presumably as a followup on this thread.
And I'm proposing that "time T" be about 11pm PST (a bit over
twelve hours from when I write this). Committers, please plan
to be idle for a few hours on either side of that, just to make
this conversion easier on me. :)
Comments?
I've not done one of these transitions before, so I'm not quite
clear on what could trip anyone up if they don't re-clone. But
I know that re-cloning is safe, and will be a lot cheaper than
the original bloated clones were. :)
