бэкэнд для быстрых импортеров данных Git (Backend for fast Git data importers)
CRASH REPORTS
If fast-import is supplied invalid input it will terminate with a
non-zero exit status and create a crash report in the top level
of the Git repository it was importing into. Crash reports
contain a snapshot of the internal fast-import state as well as
the most recent commands that lead up to the crash.
All recent commands (including stream comments, file changes and
progress commands) are shown in the command history within the
crash report, but raw file data and commit messages are excluded
from the crash report. This exclusion saves space within the
report file and reduces the amount of buffering that fast-import
must perform during execution.
After writing a crash report fast-import will close the current
packfile and export the marks table. This allows the frontend
developer to inspect the repository state and resume the import
from the point where it crashed. The modified branches and tags
are not updated during a crash, as the import did not complete
successfully. Branch and tag information can be found in the
crash report and must be applied manually if the update is
needed.
An example crash:
$ cat >in <<END_OF_INPUT

# who is that guy anyway?
data <<EOF
this is my commit

$ git fast-import <in
