all archives, all items are read to build a unified view.
files are represented by a same-name directory with the versions of the file.
A filename suffix computed by adler32(chunkids) is used to disambiguate the versions.
also: refactor code a little, create methods for leaves, inner nodes.
we will not get() objects that have a segment entry larger than MAX_OBJECT_SIZE.
thus we should never produce such entries.
also: introduce repository.MAX_DATA_SIZE that gives the max payload size.
There are persistent questions why output from options like --list
and --stats doesn't show up. Also, borg currently isn't able to
show *just* the output for a given option (--list, --stats,
--show-rc, --show-version, or --progress), without other INFO level
messages.
The solution is to use more granular loggers, so that messages
specific to a given option goes to a logger designated for that
option. That option-specific logger can then be configured
separately from the regular loggers.
Those option-specific loggers can also be used as a hook in a
BORG_LOGGING_CONF config file to log the --list output to a separate
file, or send --stats output to a network socket where some daemon
could analyze it.
Steps:
- create an option-specific logger for each of the implied output options
- modify the messages specific to each option to go to the correct logger
- if an implied output option is passed, change the option-specific
logger (only) to log at INFO level
- test that root logger messages don't come through option-specific loggers
They shouldn't, per https://docs.python.org/3/howto/logging.html#logging-flow
but test just the same. Particularly test a message that can come from
remote repositories.
