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.
Fixes#526, #573, #665, #824
removed --log-level due to overlap with how --verbose works now.
for consistency, added --info as alias to --verbose (as the effect is
setting INFO log level).
also added --debug which sets DEBUG log level.
note: there are no messages emitted at DEBUG level yet.
WARNING is the default (because we want mostly silent behaviour,
except if something serious happens), so we don't need --warning
as an option.
README.rst (shown on github and also at the start of the html docs) shall
be like an elevator speech - convince readers in a very short time.
this is most important, everything else can come after we got the reader's interest.
include README into docs to avoid duplication.
also include CHANGES into docs.
add developer docs, move examples from tox.ini there
add separate support docs
remove glossary, most of what was there can be understood by an admin from context
move attic and compatibility note to the end
