These are fsck warnings. Presumably you've enabled transfer.fsckObjects
(or fetch.fsckObjects) in your config file.

These lines are expected for git.git. It's an old project, and there are
objects in the early part of the history that have some (mostly
harmless) quirks. In this case, the v0.99 tag doesn't have a "tagger"
field, and a number of old tree entries have mode "100664" rather than
"100644" (we later standardized on a few modes, since recording the
exact group mode on people's systems was prone to noise).

Since a git clone transmits the full history, those funny objects will
live on forever.

You can safely ignore them, but if you want to quiet the noise you can
put:

  [fetch "fsck"]
  badFileMode = ignore
  missingTaggerEntry = ignore

in your ~/.gitconfig file.

-Peff

PS There's one other small oddity, which is that running "git fsck" in
   the resulting clone will show only the tag warning. That's because
   fsck doesn't check badFileMode unless you also pass "--strict". But
   fetch/push checks are always done in strict mode. TBH I am not sure
   that is wise, but the behavior here is mostly historical. I suspect
   it would be good for somebody to take a careful look and clean up the
   severity of the various warnings (some of which are security
   relevant, and some of which are just mild misconfigurations or old
   bugs).

Very true for people who do not have much control in what objects
are added to the project, but for narrow audiences who hack on Git,
it is not advisable to use for in a repository where you are adding
new objects, using versions of Git you are experimenting with.  With
these configuration, problems in these two classes in your new
objects will also be ignored.

Listing names of these objects in a file and pointing it with the
fsck.skiplist configuration variable is more involved but exempts
the listed old-and-known-to-have-known-kind-of-funnies while
noticing if you add more bad objects.  If I am counting correctly,
we have only one bad tag, with 98 bad trees.

Curiously, "git ls-tree 10344b81045" (just picked a random tree
object from the list) does not show any bad modes, as the code
normalizes the mode bits while reading.  "git cat-file -t tree"
can of course show the badness on the same object.
