#
# * include management of a persistent nodemap in the main docket
# * enforce a "no-truncate" policy for mmap safety
#      - for censoring operation
#      - for stripping operation
#      - for rollback operation
# * proper streaming (race free) of the docket file
# * track garbage data to evemtually allow rewriting -existing- sidedata.
# * Exchange-wise, we will also need to do something more efficient than
#   keeping references to the affected revlogs, especially memory-wise when
#   rewriting sidedata.
# * introduce a proper solution to reduce the number of filelog related files.
# * use caching for reading sidedata (similar to what we do for data).
# * no longer set offset=0 if sidedata_size=0 (simplify cutoff computation).
# * Improvement to consider
#   - avoid compression header in chunk using the default compression?
#   - forbid "inline" compression mode entirely?
#   - split the data offset and flag field (the 2 bytes save are mostly trouble)
#   - keep track of uncompressed -chunk- size (to preallocate memory better)
#   - keep track of chain base or size (probably not that useful anymore)

# This setting controls creation of a rebase_source extra field

# useful eg for incrementally converting changesets and then
# rebasing them onto an existing repo.
# WARNING: this is an advanced setting reserved for people who know
# exactly what they are doing. Misuse of this setting can easily
# result in obsmarker cycles and a vivid headache.
