# rev_map:

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

I don't trust the each() function on unless I created %hash myself

because the internal iterator may not have started at base.
