Hi,
I would like to export our whole git repository to patches, and then
reconstruct it again from scratch. Following the man page of "git
fast-export":
$ git clone git://git.sympy.org/sympy-full-history-20081023.git
$ cd sympy-full-history-20081023
$ git fast-export --all --export-marks=marks > patches
$ cd ..
$ mkdir sympy-new
$ cd sympy-new
$ git init
$ git fast-import --export-marks=marks < ../sympy-full-history-20081023/patches
git-fast-import statistics:

---------------------------------------------------------------------
However, the repository is very different to the original one. It
contains only 191 patches:
$ git log --pretty=oneline | wc -l
191
and it only contains couple files. Compare this with the original repository:
$ git log --pretty=oneline | wc -l
2719
What am I doing wrong? Is there some other way to do it? I also tried
"git format-patch" and "git am" and that almost works, only it changes
hashes. Is there some way to tell "git am" to preserve the hash?
Thanks,
Ondrej
