2004 # Tie::File seems to be prone to offset errors if revisions get sparse,
2005 # it's not that fast, either. Tie::File is also not in Perl 5.6. So
2006 # one of my favorite modules is out :< Next up would be one of the DBM
2007 # modules, but I'm not sure which is most portable...
2009 # This is the replacement for the rev_db format, which was too big
2010 # and inefficient for large repositories with a lot of sparse history
2013 # The format is this:
2014 # - 24 bytes for every record,
2015 # * 4 bytes for the integer representing an SVN revision number
2016 # * 20 bytes representing the sha1 of a git commit
2017 # - No empty padding records like the old format
2018 # (except the last record, which can be overwritten)
2019 # - new records are written append-only since SVN revision numbers
2020 # increase monotonically
2021 # - lookups on SVN revision number are done via a binary search
2022 # - Piping the file to xxd -c24 is a good way of dumping it for
2023 # viewing or editing (piped back through xxd -r), should the need
2025 # - The last record can be padding revision with an all-zero sha1
2026 # This is used to optimize fetch performance when using multiple
2027 # "fetch" directives in .git/config
2029 # These files are disposable unless noMetadata or useSvmProps is set
