support platforms with no os.link, fixes#4901
if we don't have os.link, we just extract another copy instead of making a hardlink.
for that to work, we need to have (and keep) the chunks list in hardlink_masters.
Looks like the minimum requirement for correct operations
on ARMv6 in non-fixup mode is xxhash 0.7.2.
note: this does not compile due to the experimental stuff in xxh3.h.
the problem was that after a resize that was triggered by too few
empty buckets, the rebuilt new hash table had entries at different
positions than before, but the idx where to SET the entry was not
recomputed afterwards.
universally mark all osx builds as allowed failures
since a while, travis-ci is way too slow on their OS X machines, so they kill our tests after 50 minutes...
- Added "Will move with BORG_CONFIG_DIR variable unless specified." to BORG_SECURITY_DIR info.
- put BORG_SECURITY_DIR immediately below BORG_CONFIG_DIR (and moved BORG_CACHE_DIR up before them).
create: tell that "Calculating size" time and space needs are caused by --progress
It took me several days to figure out that `--progress` was the culprit to Borg being SIGKILL'd by the kernel, because of OOM, and because of I enabled progress option. This elaborates on what's the calculation for.
from https://borgbackup.readthedocs.io/en/stable/usage/general.html#date-and-time
Unless otherwise noted, we display local date and time.
Internally, we store and process date and time as UTC.
OK, that does not directly say something about --timestamp, but as the cli is also part of the user interface (as output is), this might mean that maybe not the test needs fixing, but our processing of that option.
But, the docs also say:
--timestamp TIMESTAMP
manually specify the archive creation date/time (UTC, yyyy-mm-ddThh:mm:ss format).
Alternatively, give a reference file/directory.
So, using UTC there is a documented feature, although it is different from output using localtime.
So, the test fix in this PR is correct according to the docs. \o/
macOS: to cover some rather old and some rather new python
(not 3.8 though, but 3.8.0 is tested on linux).
linux: to test on 3.7 releases also. stop testing 3.6-dev.
The RepositoryCache used `os.statvfs` which is not available on Windows.
`shutil.disk_usage` provides the same information but in a cross platform way.
