- can create 0-byte files now
- frees space early (avoids running out of disk space at repo init time)
- creates multiple reserve files, so we do not only reserve some space,
but also some inodes
- only print output if there is an error RC
- if make_files makes us run out of space, that is not interesting, just start
a new iteration from scratch
added try/finally (the code in between was just indented, no
other code changes) to make sure it sets self.index back to None,
even if the code crashes e.g. due to an IntegrityError caused
by an incomplete segment caused by a disk full condition.
also, in prepare_txn, create an empty in-memory index if transaction_id
is None, which is required by the Repository.check code to work correctly.
If the index is not empty there, it will miscalculate segment usage
(self.segments).
this is so that e.g. cron jobs do not hang indefinitely if yes() is called,
but it will just default to "no" if not tty is connected.
if you need to enforce a "yes" answer (which is not recommended for
the security critical questions), you can use the environment:
BORG_CHECK_I_KNOW_WHAT_I_AM_DOING=Y
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.
