The fast import stream protocol is pretty simple. All the filter really
needs to do is pass through everything that isn't a 'commit' command. And
for the 'commit' command, it only needs to do something with the 'author'
and 'committer' lines; passing through everything else.
And how do you propose to find the commit commands without parsing all
the other commands? If you randomly look for lines that begin with
'commit /refs' you might end up in the middle of a commit message or
the contents of a file.
I didn't say you didn't have to parse the protocol. I said that the
protocol is pretty simple.
I agree that an additional filter _may_ decrease performance somewhat if you
are already CPU constrained. But I suspect that the effect would be
negligible compared to the all of the SHA-1 calculations.
Well. If it's so easy surely you can write one quickly, and I can measure it.
Not my itch; You care, you do it.
