Hmm.. I finally tried to import the bkcvs kernel tree into git, and while
I'm cursing the slowness of CVS (I'm _hoping_ that part of the problem is
just that CVS is especially slow with old versions of files, and that the
import will eventually start speeding up), there's definitely something
wrong going on with new files in an archive...
In particular, they always end up being imported as zero-sized empty
files, and will be filled in only later if that file is ever touched
again. In other words, the resulting git tree ends up being bogus.
The command line I used was
git cvsimport -d /home/torvalds/bkcvs -p --bkcvs linux-2.5
and I wonder if it's the "--bkcvs" thing that confuses cvsimport, but I
also wonder if anybody has actually tried this before. With or without
the --bkcvs line, I get
Argument "28213 has collisions" isn't numeric in addition (+) at
/home/torvalds/bin/git-cvsimport-script line 600, <CVS> line 1.
* UNKNOWN LINE * PatchSet 28209 has collisions

Sadly, since I don't know perl, I can't tell whether this is a problem
with cvsps on the kernel, or the cvsimport perl script. I'm going to try
my old hacky C + shell alternative next just to see, but I thought I'd ask
whether people have tried this before and already know what's wrong.
Btw, looking at what the perl script _seems_ to do, it does seem to do
insane things for the local CVS archive case. As far as I can tell from
the spaghetti that is perl, it uses a CVS server to handle even the local
file case, which just _can't_ be right. I realize you'd want to do that to
avoid connecting millions of times, but maybe it's better to use something
like cvsnup to download the whole thing, and then always use a local CVS
archive?
