it seems it is possible that the chunks files are copied but *not*
converted. this may have happened here because the conversion was
interrupted, although the specific scenario is still unclear (but it
did happen during manual tests here). therefore reproducing this
problem seems to be difficult, hence the lack of tests for this
specific issue.
since we consider the header replacement code to be safe, that we
always convert shouldn't pose any additional threat to the existing
borg chunk cache.
this resolves bug #something where the index file could not be
converted, completely breaking conversion.
it seems that, during some refactoring, the index conversion code was
completely dropped. this was missed by the unit tests because the repo
can still be opened by the constructor even though the index is
invalid, so tests need improvements there.
Moved the list of dependencies to the corresponding subsection.
Collected all preparation steps under one heading.
Added link to the Arch Linux AUR package.
Install docs for OS X.
This is what attic used by default, but borgbackup defaults to "no compression".
I just adjusted the command invocation, so we can keep the example output
(which shows that stuff was compressed).
Also: add FAQ item about compression.
In one case removed the |project_name| and |git_url| variables to fix
the display of the code block. Shouldn't be problematic, as they are not
used consistently in this document anyway.
Put two notes in their own nice '.. note::' blocks.
it seems to keep .tox envs even if one removes stuff from requirements file.
if that stuff causes troubles, as here with pytest-benchmark, the troubles stay...
pytest-benchmark (and its dependency "statistics") needs py 3.3+.
we do not want to run benchmarks on travis anyway, but even its presence
makes trouble due to this, so we just remove it from there again.
as --benchmark-skip is also removed from tox configuration, this means benchmarks
are run by default when pytest-benchmark is installed.
Instead of "realistic data", I chose the test data to be either all-zero (all-ascii-zero to be precise)
or all-random and benchmark them separately.
So we can better determine the cause (deduplication or storage) in case we see some performance regression.
"help" is benchmarked to see the minimum runtime when it basically does nothing.
also:
- refactor archiver execution core functionality into exec_cmd() so it can be used more flexibly
- tox: usually we want to skip benchmarks, only run them if requested manually
- install pytest-benchmark - run tox with "-r" to have it installed into your .tox envs
this still doesn't quite work: our sidebar is gone, so no more useful
links and related projects. we also loose the link to github and the
RTD popup, although the latter still needs to be confirmed on RTD
infra
this was a remnant of when i was writing the converter/upgrader code,
and was destined to be a general progress message in the migration
process. i removed a more technical, internal debugging message in
exchange
