this has never worked as intended as the function was not using the computed "fields[1]" value at all.
plus there were type issues after that was fixed.
if the borg.exe binary is not available in PATH, binary tests are skipped.
source tests are run without forking (for better speed, esp. on travis).
binary tests need forking the binary, of course.
for source tests, some tests check for an exception to happen.
for a forked binary, we of course can only check the exit code, which is non-zero in that case.
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.
this function was over-coupling the cache system and the statistics
module. they are now almost decoupled insofar as the cache system has
its own rendering system now that is called separately.
furthermore, we have a much more flexible formatting system that is
used coherently between --progress and --stats
the degenerate case here is if we want to change the label in the
statistics summary: in this case we need to override the default
__str__() representation to insert our own label.
i saw the errors in my ways: __format__ is only to customize the
"format mini-language", what comes after ":" in a new string
format. unfortunately, we cannot easily refer to individual fields in
there, short of re-implementing a new formatting language, which seems
silly.
instead, we use properties to extract human-readable versions of the
statistics. more intuitive and certainly a more common pattern than
the exotic __format__().
also add unit tests to prove this all works
we stop enforcing a minimum width for fields, it changes only on
logarithmic boundaries, so not a big problem. string conversion is
implicit
this gives us a little more width for the path
we use the new get_terminal_size() function, with a fallback for
Python 3.2. we default to 80 columns.
then we generate the stats bit and fill the rest with the path, as
previously, but with a possibly larger field.
note that this works with resizes in my test (uxterm)
the --stats output would be slightly garbled by --progress, because of
the \r that is output at the last line...
example:
initializing cache
reading files cache
processing files
------------------------------------------------------------------------------ s/twotone
Archive name: 2015-10-15-test
a single -v flag shouldn't flood the console with all the files in the
path specified, it makes -v basically useless
this way, -v can also be used with --progress to have nicer output:
initializing cache
reading files cache
processing files
5.20 GB O 2.66 GB C 25.13 MB D 27576 N baz/...
as it was, surrogates were not always removed, for example
we may also want to output at different levels or control if we want
to print unchanged files and so on
without this, there would be a solid 20 seconds here without any sort
of output on the console, regardless of the verbosity level. this
makes nice incremental messages telling the user that borg is not
stalled (or waiting for a lock, for that matter)
the "processing files" message is a little clunky, as we somewhat
abuse the cache to figure out if we are just starting... but it helps
if there are problems reading the actual files: it tells us the
initialization is basically complete and we're going ahead with the
reading of all the files.
the old name still works, but emits a deprecation warning suggesting the new name.
this is a followup to 4fd06e2634, which added "-x" (as seen in "du").
Moved the list of dependencies to the corresponding subsection.
Collected all preparation steps under one heading.
