this is needed for tools like borgweb (or in general: when the rc value / exit status should
be logged for later review or directly seen on screen).
this is off by default, so the output is less verbose (and also does not fail tests which
counts lines).
parse_args concentrates on only processing arguments, including pre and post processing.
this needs to be called before run(), which is now receiving the return value of parse_args.
this was done so we can have the parsed args outside of the run function, e.g. in main().
subclasses of "Error": do not show traceback
(this is used when a failure is expected and has rather trivial reasons and usually
does not need debugging)
subclasses of "ErrorWithTraceback": show a traceback
(this is for severe and rather unexpected stuff, like consistency / corruption issues
or stuff that might need debugging)
I reviewed all the Error subclasses whether they fit into the one or other class.
Also: fixed docstring typo, docstring formatting
the reason for a slow msgpack can be:
- pip install: missing compiler (gcc)
- pip install: missing compiler parts (e.g. gcc-c++)
- pip install: cached wheel package that was built while the compiler wasn't present
- distribution package: badly built msgpack package
there were 2 issues:
lock used another pid and tid than release because daemonize() made it different processes/threads.
solved by just determining PID only once and not using TID any more.
the other issue was that the repo needed and explicit closing.
just to avoid rounding / precision issues with floating point computations on py < 3.3
I used 2 hardcoded "full second" values on the input file and check if they get restored
correctly.
All normal informational output is now logged at INFO level.
To actually see normal output, the logger is configured to level INFO also.
Log levels:
WARNING is for warnings, ERROR is for (fatal) errors, DEBUG is for debugging.
logging levels must only be used according to this semantics and must not be
(ab)used to let something show up (although the logger would usually hide it)
or hide something (although the logger would usually show it).
Controlling the amount of output shown on INFO level:
--verbose, --progress, --stats are currently used for this.
more such flags might be added later as needed.
if they are set, more output is logged (at INFO level).
also: change strange setup_logging return value
this way the version can be discovered by scripts without having to
part the output of 'help'.
it is removed from the 'help' output itself because it is prettier
without the complete version number, and then the description can be
reused elsewhere as well without needing the version number
