- timezone aware timestamps
- str representation with +HHMM or +HH:MM
- get rid of to_locatime
- fix with_timestamp
- have archive start/end time always in local time with tz or as given
- idea: do not lose tz information
then we know when a backup was made and even from
which timezone it was made. if we want to compute
utc, we can do that using these infos.
this makes a quite nice archives list, with timestamps
as expected (in local time with timezone info).
at some places we just enforce utc, like for the
repo manifest timestamp or for the transaction log,
these are usually not looked at by the user.
since python 3.7, .isoformat() is usable IF timespec != "auto"
is given ("auto" [default] would be as evil as before, sometimes
formatting with, sometimes without microseconds).
also since python 3.7, there is now .fromisoformat().
There are some other places with subprocesses:
- borg create --content-from-command
- borg create --paths-from-command
- (de)compression filter process of import-tar / export-tar
implemented by introducing one level of indirection, the limit is now
very high, so it is not practically relevant any more.
we always use the indirection (storing the metadata stream chunk ids list not
directly into the archive item, but into some repo objects referenced by the new
ArchiveItem.item_ptrs list).
thus, the code behaves the same for all archive sizes.
work around setuptools puking about:
############################
# Package would be ignored #
############################
Python recognizes 'borg.cache_sync' as an importable package,
but it is not listed in the `packages` configuration of setuptools.
'borg.cache_sync' has been automatically added to the distribution only
because it may contain data files, but this behavior is likely to change
in future versions of setuptools (and therefore is considered deprecated).
Please make sure that 'borg.cache_sync' is included as a package by using
the `packages` configuration field or the proper discovery methods
(for example by using `find_namespace_packages(...)`/`find_namespace:`
instead of `find_packages(...)`/`find:`).
You can read more about "package discovery" and "data files" on setuptools
documentation page.
hopefully this is the final fix.
after first fixing of #6400 (by using os.umask after mkstemp), there
was a new problem that chmod was not supported on some fs.
even after fixing that, there were other issues, see the ACLs issue
documented in #6933.
the root cause of all this is tempfile.mkstemp internally using a
very secure, but hardcoded and for our use case problematic mode
of 0o600.
mkstemp_mode (mosty copy&paste from python stdlib tempfile module +
"black" formatting applied) supports giving the mode via the api,
that is the only change needed.
slightly dirty due to the _xxx imports from tempfile, but hopefully
this will be supported in some future python version.
