2608# Tie::File seems to be prone to offset errors if revisions get sparse,
2609# it's not that fast, either. Tie::File is also not in Perl 5.6. So
2610# one of my favorite modules is out :< Next up would be one of the DBM
2611# modules, but I'm not sure which is most portable...
2612#
2613# This is the replacement for the rev_db format, which was too big
2614# and inefficient for large repositories with a lot of sparse history
2615# (mainly tags)
2616#
2617# The format is this:
2618# - 24 bytes for every record,
2619# * 4 bytes for the integer representing an SVN revision number
2620# * 20 bytes representing the sha1 of a git commit
2621# - No empty padding records like the old format
2622# (except the last record, which can be overwritten)
2623# - new records are written append-only since SVN revision numbers
2624# increase monotonically
2625# - lookups on SVN revision number are done via a binary search
2626# - Piping the file to xxd -c24 is a good way of dumping it for
2627# viewing or editing (piped back through xxd -r), should the need
2628# ever arise.
2629# - The last record can be padding revision with an all-zero sha1
2630# This is used to optimize fetch performance when using multiple
2631# "fetch" directives in .git/config
2632#
2633# These files are disposable unless noMetadata or useSvmProps is set
