Only what cvsps misses, or rather, does not know what to do with (google
CVSPS_NO_BRANCH for details). Those files or changes are basically
orphaned. However, I will send a list of the files along with their
revisions to the maintainers and you can decide what to do with them.
Frankly I wouldn't worry about it to that level - if that level of digging
is required to find out past history, the best thing to do is to look
directly at the old CVS repository.
Those orphaned changes are probably the result of "cvs admin" hacks and so
on. In which case they were probably orphaned for a reason.
So, a suggestion that e.g. eCos should switch over to git because it
is already in use on other projects is unlikely to get much attention
from the maintainers. A serious offer to do the hard work will get
much more attention, especially if it is backed up with experimental
data and explanations of why some of the problems with cvs are just
too hard to work around.
My offer in my previous email is serious. Little skin off my nose and
most CPU cycles are free. I have already developed my script in-house
for an internal conversion and so we can evaluate the different DRCS
systems. What the maintainers or community choose to do with the repo
is up to them, but moving an hg repo to sourceware will be has hard as
"hg clone http://hg.ecoscentric.com/ecos";, while converting it to git or
bzr a matter of exporting the patchsets (this time without error) from
hg after cloning it and importing them.
I for one would like to take you up on that! Even if the choice isn't hg
that effort would be useful and not wasted.
