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 + # my very first test commit + commit refs/heads/master + committer Shawn O.
